Next, the details of the columns 2 and the beams 3 will be described. FIG. 7 is a schematic perspective view of a conventional connecting structure for a building frame, and FIG. 8 is a front sectional view of the same. As shown in FIGS. 7 to 8, the pillar 2 is
Hollow prisms 5 are erected vertically and arranged vertically. The hollow prisms 5 are connected by a connecting block 101. The side walls of the connecting block 101 are connected to the beam connecting members 10 in the front, rear, left and right respectively.
2 is installed. This connecting block 101 is composed of a hollow prismatic main body 103 having plate-like diaphragms 104 attached to the upper and lower sides thereof, and an attaching plate 108 attached to the upper and lower inner peripheries of the main body 103, respectively.
A hollow prism 5 is fitted around the outer circumference of 108. The beam connecting member 102 has a groove welded to the main body 103, and a bolt insertion hole 107 for connecting the beam connecting member 102 to the beam 3 is bored at the other end. Reference numeral 105 is a backing plate, and 106 is a welded portion. In the above-mentioned conventional example, a large number of beam connecting members 102 are welded to the connecting block 101 of the pillar 2 in advance at the factory, and the pillar 2 is loaded on a truck and transported to the site.

[0005]

SUMMARY OF THE INVENTION However, a beam connecting member
All the bolt insertion holes drilled in the 102, the beam 3 and the splice plate 110 are drilled at the factory and inserted in the field, but the work of tightening a large amount of high-strength bolts 15 in these bolt insertion holes is repeated. The bolt insertion holes are made larger than the high-strength bolts 15 in order to facilitate work in the field. For this reason,
An error occurs when tightened, and further, since the splice plate 110 sandwiches the beam 3 and the beam connecting member 102 from both sides, the error variation becomes large. In particular, since the connecting portion between the beam connecting member 102 and the beam 3 is a portion that is easily deformed by stress concentration, the hollow prism 5 and the beam 3 are twisted or tilted, causing a design error. For this reason, the beam 3 and the column 2 cannot be accurately connected to each other, and there is a problem that the assembly accuracy of the connection structure 1 is poor.

[0006] In addition, since the beam connecting member 102 acts as a protrusion on the column 2 and is extremely obstructive, it is dangerous to carry the column 2. Also, since the column is bulky, many columns 2 are placed on the truck. There is a problem that you can not.

Further, in the factory, in order to make the connecting block 101, the hollow prismatic body 103 and the diaphragm 104 are used.
Are welded to each other, and then the contact plates 108 are welded to the respective upper and lower inner circumferences of the main body 103. In this way, conventionally, there are many parts to be welded, and since welding must go through multiple steps of temporary assembly, temporary welding, and main welding, it takes a lot of time and labor for the welding work in the factory. There is. In addition, U. Since the T inspection was performed, the inspection cost is high, and if a welding defect is found, after repairing it, U. The T-test must be repeated. On the other hand, in the field, in order to firmly hold the beam connecting member 102 and the beam 3, a large number of splice plates are used.
110 is used, and the high-strength bolt 15 that tightens the bolt insertion hole 111 of the splice plate 110 and the bolt insertion hole 107 of the beam 3 or the beam connecting member 102 requires a larger number, so the number of parts is increased. There are so many, and it takes a lot of time and effort to carry out on-site connection and assembly work. As mentioned above,
There is a problem that a great number of man-hours are spent on welding work and assembly work.

In view of the above circumstances, the present invention improves the accuracy of the frame, allows parts such as columns and beams to be loaded on a truck without danger, increases the number of columns loaded on the truck, and increases the strength of the block. It is an object of the present invention to provide a prismatic connection block for a building frame, a beam, and a connection structure using the same, which reduces the number of parts and reduces the number of assembly work and welding work.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an assembly view of an embodiment using a prismatic connection block and a beam for a building frame of the present invention, and FIG. 2 is a front sectional view of the same. As shown in FIGS. 1 and 2, the connection structure for the building frame is composed of a pillar 2 standing upright and a beam 23 connected to the pillar 2. The columns 2 are hollow prisms 5 that are alternately connected by the prism connection blocks 4. In this prismatic connection block 4, a main body 8 is formed into a hollow prismatic shape, an upper end insertion portion 6 is formed in an upper portion of the main body 8, and a lower end insertion portion 7 is formed in a lower portion thereof. It is formed so that it can be densely inserted into the inner periphery of the hollow prism 5. Therefore, the columns 2 can be densely connected to the upper end insertion portion 6 and the lower end insertion portion 7 of the hollow prism 5, so that if the hollow prism 5 and the prism connection block 4 are alternately connected one after another, It can be the pillar 2 of the frame of a multi-storey high-rise building. In addition, the upper end insertion portion 6 and the lower end insertion portion 7 of the prismatic connection block 4
Since they are substantially the same, the prism connecting blocks 4 may be arranged upside down and connected to the hollow prism 5. Further, since the diaphragm 104 and the contact plate 108, which are conventionally required to connect the hollow prism 5 and the prism connecting block, are not necessary, the number of parts can be reduced, and the diaphragm 104
The labor and time for welding the touch plate 108 can be saved.

As shown in FIGS. 1 and 2, a large number of female screw holes 10 are formed as coupling holes on the four side walls of the main body 8 of the prismatic connection block 4. Further, the beam 23 is such that the plate 12 is attached to the end surface of the horizontal beam 17, and the plate 12 is formed with a bolt insertion hole 13 at a position corresponding to the female screw hole 10.
A high-strength bolt 15 can be connected to 13 and the female screw hole 10 to fasten the main body 8 of the prismatic connection block 4 and the plate 12 of the beam 23. Female screw hole 10 of the prismatic connection block 4
Since both the bolt insertion holes 13 of the plate 12 can be accurately drilled at the factory, the accuracy of the connecting portion between the pillar 2 and the beam 23 can be improved, and the inclination and distortion of the connecting structure 1 can be reduced. .

The connecting hole of the prismatic connecting block 4 is not limited to the female screw hole, but may be a through hole and may be tightened by a tightening bolt as described below. As shown in FIG. 3, the main body 8 of the prismatic connection block 4 has a large number of through holes 19 provided with no female screw on its four side surfaces, and each of the through holes 19 has a fastening bolt 40. Has been inserted. In this fastening bolt 40, a hollow flexible washer 45 is inserted into a bolt 41, and further a hollow collar 44 is inserted, 43 is a washer, and 42 is a nut. Before being used, the flexible washer 45 is in a stretched state and deforms when subjected to a force.

A plate 12 is attached to the main body 8 of the prismatic connection block 4.
When the nut 42 is turned and screwed in order to connect the two, the nut 42 moves to the position of the collar 44 and pushes the collar 44, and the collar 44 pushes the flexible washer 45. Due to this force, the flexible washer 45 projects outward and is bent and deformed, so that the prismatic coupling block 4 and the plate 12 can be firmly clamped by the wedge effect.

Next, the partition wall of the prismatic connecting block will be described. As shown in FIG. 1, a partition 11 having a cross shape in a plan view may be provided in the hollow portion of the main body 8 of the prismatic connecting block 4, and when the partitioning 11 is provided, the prismatic connecting block is provided. Since the strength of No. 4 is increased and the deformation of the prismatic connecting block 4 can be suppressed, the torsion of the hollow prism 5 and the inclination of the beam 23 can be suppressed. 4 to 5 are schematic perspective views of other embodiments of the connection block of the present invention. As shown in FIG. 4, a square-shaped partition wall 21 in plan view may be provided in the hollow portion of the prismatic connection block 20. Since the number of partition walls is larger than that in the first embodiment, it is stronger. Further, as shown in FIG. 5, partition walls 31 may be provided diagonally in the hollow portion of the prismatic connection block 30. By doing so, the strength can be increased with a small number of partition walls. That is, the number of partition walls may be any number as long as the strength is obtained, and may not be orthogonal. Therefore, depending on the required strength of the frame to be constructed, it is preferable to use a connecting block provided with a partition wall that can withstand this strength. The partition may be omitted as long as the strength of the prismatic connecting block is sufficient.

As described above, when the connecting block, beam and connecting structure for the building frame of the present invention are used, the beam connecting member 102 which has been conventionally required is not required and the protrusion is eliminated, so that it is easy to carry and bulky. Many parts can be loaded on the truck and it is safe. And, not only the many splice plates 110 that were necessary in the past are not needed at all, but the very many high-strength bolts 15 that fasten the splice plate 110 are not necessary. Markedly reduced. in this way,
Since the number of parts can be significantly reduced, the assembly work time can be reduced. Further, since the number of welding points is reduced, the time required for the welding work time is reduced. In fact, as a result of welding work using the prismatic connection block 4 and the beam 23 of the present invention, the present inventor has been able to reduce approximately 50% of the total welding time required to assemble a building frame. Furthermore, since the bolt insertion hole 13 of the plate 12 and the coupling hole of the prismatic coupling block 4 can be accurately drilled at the factory, the assembled coupling structure 1 is highly accurate. Therefore, the accuracy of the building frame can be improved and the total working time can be reduced.

According to the prism connection block of claim 1,
No matter how many floors are high-rise buildings, if you connect the hollow prisms alternately, you can stack the pillars high up to many floors, and you do not need a beam connecting member. Since it does not become bulky, it can be safely loaded on the truck, the number of parts loaded on the truck can be increased, and since the diaphragm and the touch plate are not required, the number of welding points can be reduced and the welding man-hours can be reduced. You can According to the prismatic connection block of the second aspect, since the strength of the prismatic connection block can be increased by the lattice-shaped partition wall, it is possible to suppress distortion and inclination of the hollow prismatic or beam without resisting stress concentration and deformation. . According to the beam of the third aspect, since the bolt insertion holes of the plate can be accurately drilled in the factory in correspondence with the positions of the coupling holes of the prismatic connection block, it is possible to make a very accurate building frame. According to the connection structure of claim 4, it is possible to eliminate a large number of splice plates, and it is possible to significantly reduce the number of parts such as high-strength bolts, and to reduce the number of prismatic connection blocks and beams to high strength. Since they can be easily connected by bolts, the number of assembly work steps can be reduced.
