Japanese Patent Laid-Open No. 10-8574

  By the way, adjustment of the inclination of the column and the position of the beam (hereinafter, this adjustment is referred to as “rebuilding”), for example, a plurality of tendons are wound around the column or beam, and the columns or beams are laid from a plurality of directions by these tendons. This is done by pulling.

  However, it takes time to wind the tension material around the pillars and beams.

  In view of the above-described facts, an object of the present invention is to provide a method for constructing a column beam member that can reduce the labor of attaching a tendon material.

  The construction method of the column beam member according to claim 1 includes a beam installation step of installing the beam member so that the beam end portion overlaps the gusset plate protruding from the column member in a side view, and the beam end portion Tensile members attached to the tendon attachment jig by inserting rod-like temporary anchor members into the side holes and through holes formed in the gusset plates, respectively, and fixing the tendon attachment jigs on both sides of the beam ends. Reconstructing step of tensioning, removing the tension material attaching jig and the bar-like temporary retaining member from the beam end, inserting the bar-shaped main member into the through hole, and the column member and the beam end And a column beam member joining step.

  According to the construction method of the column beam member according to claim 1, in the beam installation step, the beam member is installed so that the beam end portion overlaps the gusset plate protruding from the column member in a side view.

  Next, in the rebuilding process, rod-like temporary retaining members are inserted into the through holes respectively formed on the side surface of the beam end portion and the gusset plate, and the tension material attaching jigs are fixed to both sides of the beam end portion, respectively. At this time, the beam end and the gusset plate are temporarily joined by the bar-like temporary fixing member. Then, the tension members attached to the tension material attachment jigs on both sides are tensioned, and the beam ends are pulled from both sides, thereby rebuilding the beam members and the column members temporarily joined to the beam members.

  Next, in the column beam member joining step, the tendon attachment jig and the bar-like temporary retaining member are removed from the beam end. Then, a rod-shaped main member is inserted into the side surface of the beam end and through holes formed in the gusset plate to join the column member and the beam end (main joining).

  As described above, in the present invention, in the rebuilding process, the bar-like temporary retaining members are inserted into the through holes formed in the side surface of the beam end and the gusset plate, respectively, and the tension material attaching jigs are fixed to both sides of the beam end. To do. Therefore, the labor for attaching the tension material to the beam member is reduced.

  Further, since the tension member attaching jig is fixed to the beam end by diverting the through hole for the rod-shaped main member, it is not necessary to form a new through hole at the beam end.

  Moreover, the tendon attachment jig is fixed to both sides of the beam end. Therefore, for example, when constructing a slab such as a reinforced concrete structure on a beam member, the tension material mounting jig and the tension material do not get in the way, and there is no need to remove the tension material mounting jig and the tension material. Therefore, the slab workability is improved.

  Further, the column accompanying the construction of the slab can be obtained by constructing the slab with the tension member attaching jig and the tension material attached to the beam end, that is, with the beam member and the column member restrained at a predetermined position by the tension material. Misalignment of the members and beam members is reduced. Therefore, the construction accuracy of the column member and the beam member is improved.

  The construction method of the column beam member according to claim 2 is the construction method of the column beam member according to claim 1, wherein the beam member has a wooden portion at least in an outer peripheral portion, and the tension material mounting jig is The rod-like temporary retaining member and the rod-shaped main member are fixed, and in the beam installation step, the gusset plate is inserted into a slit formed in the vertical direction at the beam end, and the reconstruction is performed In the step, the fixing plate is fixed in a state of being overlapped on the side surface of the beam end.

  According to the construction method of the column beam member according to claim 2, the beam member has a wood part at least on the outer periphery. In this case, for example, when a tension member is wound around the beam member to be tensioned, the tension member may bite into the outer peripheral portion of the beam member, and the outer peripheral portion may be damaged.

  On the other hand, in the present invention, in the rebuilding process, the fixing plates of the tension material attaching jig are fixed in a state where they are overlapped on the side surfaces on both sides of the beam end portion. Thereby, for example, when the tension material attached to one tension material attachment jig is tensioned, the tension force of the tension material is applied to the side surface of the beam end via the fixing plate of the other tension material attachment jig. Is distributed and transmitted. Therefore, the damage | wound etc. of the outer peripheral part of a beam end part can be suppressed.

  The construction method of the column beam member according to claim 3 is the construction method of the column beam member according to claim 1 or 2, wherein the beam is disposed on at least one side of the beam end portion in the rebuilding step. The above-mentioned tension material attaching jig for the oblique lower side to which the tension material pulling the end obliquely downward is attached and the above-mentioned tension material attaching jig for the lateral direction to which the tension material pulling the beam end part in the lateral direction are arranged. Fix it.

  According to the construction method of the column beam member according to claim 3, in the rebuilding process, the tension material mounting jig for obliquely downward and the tension material mounting jig for the lateral direction are provided on at least one side of the beam end portion. Fix them side by side. A tension material that pulls the beam end diagonally downward is attached to the tension material attachment jig for obliquely downward, and a tension material that pulls the beam end laterally is attached to the tension material attachment jig for the horizontal direction. It is done. By tensioning these tendons, the beam end can be pulled obliquely downward and laterally, so that the rebuilding accuracy of the column member and the beam member is improved.

  As explained above, according to the construction method of the column beam member according to the present invention, it is possible to reduce the labor of attaching the tendon material.

  Hereinafter, the construction method of the column beam member concerning one embodiment of the present invention is explained, referring to drawings. First, the connection structure of the wooden pillar and the wooden beam in the present embodiment will be described.

  As shown in FIG. 1, the wooden beam 40 is constructed between the wooden column 10 and a wooden column (not shown), and the beam end portions 40T on both sides thereof are joined to the joint portion 10A of the wooden column 10. Yes.

  On the wooden beam 40, a reinforced concrete slab 60 is constructed. A cutout portion 36 that exposes the core portion 12 to be described later is formed at a portion of the wooden pillar 10 that intersects with the slab 60. The core portion 12 is covered with the slab 60 by placing slab concrete constituting the slab 60 in the notch 36.

  As shown in FIG. 2, a fireproof structure is applied to the wooden pillar 10 as an example of a pillar member. The wooden pillar 10 is formed in a substantially rectangular cross section, and includes a core portion 12, a burning stop layer 14, and a burning allowance layer 20.

  The core 12 is formed in a rectangular cross section by a laminated material obtained by integrating a plurality of plate-like or prismatic wooden single materials with an adhesive or the like, and is configured to be able to support a load or the like borne by the wooden pillar 10. ing. A flame stop layer 14 is disposed outside the core 12.

  The burn-off layer 14 is a layer that stops the combustion of the burn-up layer 20 at the time of a fire (natural quenching) and suppresses the burning of the heart 12, and surrounds the heart 12. That is, the flame-stopping layer 14 covers the core 12 with a fireproof coating. The flame stop layer 14 has a plurality of mortar boards 16 and a plurality of wood boards 18 arranged alternately along the outer peripheral surface of the core 12. The mortar board 16 and the wooden board 18 are disposed along the material axis direction of the wooden pillar 10 and are joined to the outer peripheral surface of the core 12 by an adhesive or the like.

  The heat capacity of the mortar board 16 is larger than that of the wooden board 18, and by arranging the mortar board 16 and the wooden board 18 alternately, the heat capacity of the flame stop layer 14 as a whole of the core 12 and the burning allowance layer 20 is increased. It is larger than the heat capacity. A burning allowance layer 20 is disposed outside the burning stop layer 14.

  The burning allowance layer 20 as a woody part is a layer that suppresses the intrusion of fire heat into the core 12 by burning during a fire to form a carbonized layer (heat insulating layer), and surrounds the burning stop layer 14. . That is, the burning allowance layer 20 covers the burning stop layer 14 with a fireproof coating. The burning allowance layer 20 is formed of a laminated material, and is joined to the burning stop layer 14 with an adhesive or the like. In addition, the thickness (layer thickness) of the burning allowance layer 20 is appropriately set according to the required fire resistance performance (fire resistance time) required for the wooden pillar 10, the burning rate of the burning allowance layer 20, and the like.

  A groove portion 22 that exposes the core portion 12 is formed on the side surface of the joint portion 10A of the wooden pillar 10. The groove portion 22 is a rectangular long groove extending in the vertical direction, and the bracket 24 is fixed to the core portion 12 via the groove portion 22. Note that a mortar plate 38 is bonded to the inner side surface of the groove 22 by an adhesive or the like.

  The bracket 24 is formed in a substantially T shape in a plan view, and has a flange 24A fixed to the core 12 and a gusset plate 24B projecting from the flange 24A to the outside (wooden beam 40 side). Yes. The flange 24 </ b> A is overlapped on the side surface of the core 12, and is fixed to the core 12 by a plurality of bolts 26 and nuts 28 and 32 that penetrate the core 12. A groove portion 34 that accommodates the bearing plate 30 and the nut 32 is formed on the side surface of the core portion 12 opposite to the groove portion 22.

  Similar to the wooden pillar 10, the fire-resistant structure is applied to the wooden beam 40. As shown in FIG. 3, the wooden beam 40 is formed in a substantially rectangular cross section, and includes a core part 42, a burning stop layer 44, and a burning allowance layer 46 as a wooden part. Since the basic structure of the core part 42, the flame stop layer 44, and the burn margin layer 46 is the same as that of the core part 12, the flame stop layer 14, and the burn margin layer 20 of the wood pillar 10 described above, the explanation will be given. Omitted. In the wood beam 40, the upper surface of the core part 42 is covered with the slab 60 (see FIG. 1), and therefore the burn-out stop layer 44 and the burn-in allowance layer 46 are not provided on the upper side of the core part 42.

  A slit 48 that extends in the vertical direction and into which the gusset plate 24B can be inserted from above is formed in the beam end portion 40T of the wooden beam 40. The slit 48 extends from the upper surface of the wooden beam 40 to the lower portion of the core portion 42 and opens the upper surface and the end surface of the wooden beam 40.

  A gusset plate 24 </ b> B is inserted into the slit 48 from the upper surface side of the wooden beam 40. A plurality of through holes 50 and 52 are formed in the side surface 40S of the beam end portion 40T and the gusset plate 24B, respectively. The gusset plate 24 </ b> B and the beam end portion 40 </ b> T are joined by the drift pin 54 as a rod-like permanent member inserted into the through holes 50 and 52.

  Note that a wooden plug that hides the drift pin 54 may be inserted into the through hole 50. Further, as shown in FIG. 2, a wooden joint material 56 is inserted in the gap between the side surface of the wooden pillar 10 and the end surface of the wooden beam 40. The end surface of the core 12 is covered with a mortar plate 58.

  Next, the configuration of the tendon attachment jig will be described.

  As shown in FIG. 4, a tension material attaching jig 70 for obliquely downward is attached to the side surface 40S of the beam end portion 40T. A slanting material attaching jig 70 (hereinafter referred to as a “downward attaching jig”) 70 is a slanting material 86 such as a wire that pulls the beam end 40T obliquely downward to the beam end 40T (see FIG. 5). It is a jig to attach. The downward mounting jig 70 includes a fixing plate 70A as a fixing portion fixed to the side surface 40S of the beam end portion 40T, and a vertical mounting rib 70B as an attachment portion to which the tension member 86 is attached.

  The fixed plate 70A is formed in a substantially rectangular shape and is overlapped with the side surface 40S of the beam end portion 40T via a protective plate 72 such as a veneer plate. On both sides of the fixing plate 70A and the protection plate 72, a plurality of (two in this embodiment) fixing holes 74 and 76 corresponding to the predetermined through holes 50 of the beam end portion 40T are formed, respectively.

  As shown in FIG. 5, the fixing holes 74 and 76 of the fixing plate 70A and the protective plate 72 are rod-like temporary retaining members that pass through the beam end 40T and the through holes 50 and 52 (see FIG. 3) of the gusset plate 24B. The end of the bolt 78 can be inserted. The fixing plate 70 </ b> A is fixed to the side surface 40 </ b> S of the beam end portion 40 </ b> T via the protective plate 72 by the bolts 78 and the nuts 80. The protection plate 72 may be provided as necessary and can be omitted as appropriate.

  The vertical mounting rib 70B projects from the central portion of the fixed plate 70A, and a mounting hole 82 is formed in the central portion. A tension material 86 is attached to the attachment hole 82 via a hook 84. Further, the vertical mounting ribs 70 </ b> B are arranged along the vertical direction so as to easily resist the moment generated by the tension force of the tension material 86.

  Next, an example of the construction method of the column beam member according to the present embodiment will be described.

First, the beam installation process will be described.
As shown in FIG. 6, a wooden beam 40 is disposed below the gusset plate 24B protruding from each of the pair of wooden pillars 10, and the wooden beam 40 is lifted by a lifting machine (not shown), and beam ends on both sides are arranged. The gusset plates 24B are respectively inserted into the slits 48 formed in the portion 40T. Thereby, the beam end portion 40T is overlapped with the gusset plate 24B in a side view.

Next, the rebuilding process will be described.
As shown in FIG. 4, temporary bolts 78 are inserted into the beam ends 40T and predetermined through holes 50 and 52 of the gusset plate 24B. Next, the protection plate 72 and the downward mounting jig 70 are arranged on both sides of the beam end portion 40T, and the end portions of the bolts 78 are inserted into the fixing holes 76 and 74 of the protection plate 72 and the fixing plate 70A. Then, by tightening the nuts 80 at both ends of the bolt 78, the lower mounting jig 70 is fixed in a state where the fixing plate 70A is overlapped on the side surfaces 40S on both sides of the beam end 40T via the protective plate 72. . A drift pin 54 may be inserted into the other through holes 50 and 52 that are not used for fixing the lower mounting jig 70.

  Next, as shown in FIG. 5, a tension member 86 is attached to the vertical attachment rib 70 </ b> B of each downward attachment jig 70 via a hook 84. Then, the tension members 86 are tensioned by a lever block (registered trademark) or the like (not shown), and the beam end portion 40T is pulled from both sides, thereby adjusting the position of the wooden beam 40 and the inclination of the wooden column 10. In addition, you may fix the downward mounting jig 70 to which the tension | tensile_strength material 86 was previously attached to the side surface 40S of the beam end part 40T.

  Thereafter, in the slab construction process, a formwork for the slab 60 (see FIG. 1) is temporarily installed on the wooden beam 40, slab reinforcement is arranged, and slab concrete is placed and cured. Thereby, the slab 60 is constructed.

Next, the column beam member joining process will be described.
After the slab concrete is hardened, the downward mounting jig 70 and the bolt 78 are removed from both sides of the beam end portion 40T. Next, instead of the bolt 78, the main drift pin 54 is inserted into the side surface 40S of the beam end portion 40T and the through holes 50 and 52 of the gusset plate 24B, and the gusset plate 24B and the beam end portion 40T are joined (main joining). )

  Next, the effect of this embodiment will be described.

  As described above, in the present embodiment, in the rebuilding process, the bolts 78 are inserted into the through holes 50 and 52 formed in the side surface 40S of the beam end portion 40T and the gusset plate 24B, respectively, on both sides of the beam end portion 40T. The lower mounting jig 70 is fixed. Therefore, the labor for attaching the tendon 86 to the beam end 40T is reduced.

  Further, the beam end 40T and the gusset plate 24B are temporarily joined by the bolt 78. In this state, the tension members 86 attached to the lower mounting jigs 70 are tensioned, and the beam ends 40T are pulled obliquely downward from both sides, whereby the temporarily joined wooden beams 40 and wooden columns 10 are reconstructed. It can be performed.

  Further, since the downward mounting jig 70 is fixed to the beam end portion 40T by diverting the through holes 50 and 52 for the drift pin 54 provided in this way, it is not necessary to form a new through hole in the beam end portion 40T. .

  Moreover, the downward mounting jig 70 is fixed to the side surface 40S of the beam end portion 40T. That is, the downward mounting jig 70 is disposed below the slab 60 constructed on the wooden beam 40. Therefore, for example, when the slab 60 is constructed on the wooden beam 40, the downward attachment jig 70 and the tension material 86 attached to the downward attachment jig 70 do not interfere with the downward attachment. There is no need to remove the jig 70 and the tendon 86. Therefore, the workability of the slab 60 is improved. On the other hand, for example, when a tension material is wound around the beam end portion 40T of the wooden beam 40 or the notch portion 36 of the wooden column 10, the tension material becomes an obstacle when the slab 60 is constructed. Therefore, the tendon has to be removed, and it takes time to construct the slab 60.

  Furthermore, the slab 60 is constructed in a state where the downward mounting jig 70 and the tension member 86 are attached to the beam end portion 40T, that is, in a state where the wooden beam 40 and the wooden pillar 10 are constrained to a predetermined position by the tension member 86. Thereby, the position shift etc. of the wooden beam 40 and the wooden pillar 10 accompanying construction of the slab 60 are reduced. Therefore, the construction accuracy of the wooden beam 40 and the wooden pillar 10 is improved.

  Here, a burning allowance layer 46 as a wood part is provided on the outer peripheral part of the wood beam 40. For this reason, when the tension material 86 is wound around the wooden beam 40 and is tensioned, the tension material 86 may bite into the burning allowance layer 46 and the burning allowance layer 46 may be damaged. As a countermeasure against this, it is conceivable to wrap a buffer material or the like around the outer periphery of the wooden beam 40, and then wrap the tension material 86 on the wrapping material. In this case, it takes time to wrap the buffer material.

  On the other hand, in the present embodiment, in the rebuilding process, the fixing plate 70A of the lower mounting jig 70 is fixed to the side surfaces 40S on both sides of the beam end portion 40T via the protective plate 72, respectively. Thereby, for example, when the tensioning material 86 attached to one lower mounting jig 70 is tensioned, the tension of the tensioning material 86 is transmitted through the fixing plate 70 </ b> A of the other lower mounting jig 70. It is distributed and transmitted to the side surface 40S of the beam end 40T.

  Therefore, damage to the burning allowance layer 46 at the beam end portion 40T can be suppressed. In addition to this, in the present embodiment, since the protective plate 72 is disposed between the side surface 40S of the beam end portion 40T and the fixing plate 70A, the burnup layer 46 can be further prevented from being damaged.

  Further, the vertical mounting ribs 70 </ b> B of the downward mounting jig 70 are arranged along the vertical direction so as to easily resist the moment generated by the tension force of the tension material 86. Therefore, since the deformation | transformation etc. of the vertical attachment rib 70B are suppressed, durability of the downward mounting jig 70 improves. Furthermore, the downward mounting jig 70, the bolt 78, and the like can also be used to rebuild other wooden beams and wooden columns. Therefore, cost reduction can be achieved.

  Next, a modification of the above embodiment will be described.

  In the said embodiment, although the example which fixed the downward mounting jig 70 to the side surface 40S of the beam end part 40T was shown, it does not restrict to this. For example, a lateral tension material attaching jig for attaching a tension material that pulls the beam end 40T in the lateral direction may be fixed to the side surface 40S of the beam end 40T.

  Specifically, as shown in FIG. 7, a downward mounting jig 70 and a lateral tension material mounting jig (hereinafter referred to as “lateral mounting jig”) are provided on the side surface 40S of the beam end portion 40T. 90) are mounted side by side in the vertical direction. The horizontal mounting jig 90 has a fixing plate 90A as a fixing portion fixed to the side surface 40S of the beam end portion 40T, and a horizontal mounting rib 90B as a mounting portion to which the tension material 92 is attached. It is arranged on the upper side of the mounting jig 70.

  The fixing plate 90 </ b> A has the same configuration as the fixing plate 70 </ b> A of the lower mounting jig 70, but the horizontal mounting rib 90 </ b> B has a different orientation from the vertical mounting rib 70 </ b> B of the lower mounting jig 70. Specifically, the lateral mounting rib 90B is disposed along the material axis direction of the wooden beam 40 so as to easily resist the moment generated by the tension force in the lateral direction (diagonal lateral direction) of the tension member 92. ing. The other configuration of the horizontal mounting rib 90B is the same as that of the vertical mounting rib 70B.

  For example, as shown in FIG. 8, the lateral mounting jig 90 is fixed to the opposite side surfaces 40 </ b> S of the adjacent wooden beams 40. Then, the tension member 92 for the lateral direction attached to each lateral attachment rib 90B is tensioned by the lever block (registered trademark) 94, and the beam end portion 40T is pulled in the lateral direction, whereby the position of the wooden beam 40 and the quality of the wood The inclination of the column 10 can be adjusted. As indicated by a two-dot chain line, a tension member 92 is attached to a beam end 40T of one wooden beam 40 and a beam end (not shown) on the opposite side of the other wooden beam 40, and the beam end 40T may be pulled obliquely in the lateral direction.

  By fixing the lower mounting jig 70 and the lateral mounting jig 90 to the side surface 40S of the beam end portion 40T in this way, the beam end portion 40T can be pulled obliquely downward and laterally. 10 and the accuracy of reconstruction of the wooden beam 40 can be improved.

  In the present modification, the example in which the lower mounting jig 70 and the lateral mounting jig 90 are fixed to the side surfaces 40S on both sides of the beam end portion 40T is shown, but the present invention is not limited thereto. For example, the downward mounting jig 70 and the lateral mounting jig 90 are fixed to one side surface 40S of the beam end portion 40T, and the downward mounting jig 70 and the lateral direction mounting jig 90 are secured to the other side surface 40S of the beam end portion 40T. Any one of the mounting jigs 90 may be fixed. Further, only the lateral mounting jig 90 may be fixed to the side surface 40S of the beam end portion 40T. Furthermore, the number and arrangement of the downward mounting jig 70 and the lateral mounting jig 90 can be changed as appropriate.

  In addition, as the tension material mounting jig, for example, a plurality of vertical mounting ribs 70B may be provided for one fixed plate 70A, or vertical mounting ribs 70B and horizontal mounting ribs 90B may be provided. Further, the orientation and shape of the vertical mounting rib 70B and the horizontal mounting rib 90B as the mounting portion can be changed as appropriate. Further, for example, a U-shaped hook or the like may be used as the attachment portion.

  Further, the bar-like temporary retaining member is not limited to the bolt 78 having male threads cut at both ends, and may be a bolt having male threads cut only at one end. Moreover, as a rod-shaped fixing member, you may use not only the drift pin 54 but another rod-shaped member.

  Moreover, in the said embodiment, although the beam member was demonstrated to the example the wooden beam 40 to which the fireproof structure was applied, it is not restricted to this. As a beam member, you may use the wood beam of the fireproof structure formed with the laminated material, or the hybrid wooden beam which embedded the shape steel in the center part of the laminated material. Thus, the above embodiment is particularly effective for a wooden beam having a wooden part at least on the outer peripheral part. Further, a steel-framed steel beam may be used as the beam member. The same applies to the column member.

  For example, the entire wooden beam 100 shown in FIG. 9 is made of laminated material, and has a wooden portion at the center and outer peripheral portion, and a slit 102 extending in the vertical direction is formed at the beam end portion 100T. The slit 102 is formed from the lower surface to the upper surface of the wooden beam 100.

  On the other hand, the steel column 110 is formed of H-section steel. A pair of upper and lower reinforcing plates 112 are provided at the joint 110A of the steel column 110. Further, a gusset plate 114 inserted into the slit 102 of the beam end portion 100T projects from the flange portion 110F of the steel column 110. Through holes (not shown) are formed in the gusset plate 114 and the side surface 100S of the beam end portion 100T, and the gusset plate 114 and the beam end portion 100T are joined by the drift pins 54 inserted into these through holes. Yes. The downward mounting jig 70 and the like can be attached to the side surface 100S of the beam end portion 100T.

  Moreover, although illustration is abbreviate | omitted, the said embodiment is applicable also to the junction part of the gusset plate which protrudes from a steel column, and the beam edge part of a steel beam. For example, a high-strength bolt (mainly rod-like member) inserted in through holes formed in the gusset plate and the web portion, with the gusset plate protruding from the steel column superimposed on the web portion of the steel beam of H-shaped steel In addition, in the joining structure in which the steel column and the steel beam are joined by the nut, the tension member attaching jig may be attached to the side of the web portion or the gusset plate by a bolt as a temporary rod-like member instead of the high strength bolt.

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention will be described. Of course, various embodiments can be implemented without departing from the scope.
