を要している。In the above-described high-strength bolt tension bonding, when a pair of upper and lower metal joints 3 is pre-attached in a factory or on-site, the pair of metal joints 3 is used.
It is necessary to insert the beam steel 2 into the space created by the above. However, in reality, since there are various tolerances caused by the manufacturing process of the beam steel frame 2, it is often difficult to insert the beam steel frame 2 smoothly, and it takes a lot of time and labor to perform fine adjustment.

レートを介して接合してあることを特徴とする。According to the present invention, there is provided a beam-column joint,
H-shaped steel, cruciform steel (a cross-shaped web having a flange formed at each end thereof, for example, a cross-H cross-section in which a half-split H-shaped steel is provided in an orthogonal direction to an H-shaped steel web, etc. ),
A beam steel structure such as an H-shaped steel is joined to a column steel structure such as a rectangular steel pipe via a joint metal, and a beam is formed between a pair of upper and lower protrusions formed by a joint metal attached to the side surface of the column steel structure. At the beam-column joint where the upper and lower flanges of the steel are joined, place the lower flange of the beam steel on the lower protrusion
While overlapping and joining, do not overlap the upper protrusion with the upper flange of the beam steel, set it at the height of the upper flange, delete the required length of the upper flange of the beam steel in the longitudinal direction of the beam steel, and The part and the upper flange of the steel beam are joined via a splice plate.

除する場合もある。[0008] The required length of the upper flange of the beam steel frame is deleted in the longitudinal direction of the beam steel frame because the lower flange of the beam steel frame is overlapped with and joined to the lower projection, and the upper projection at the same height is joined. And the upper flange of the beam steel frame do not interfere with each other, and the upper protruding portion and the tip of the upper flange of the beam steel frame may have a slight gap or may be in close contact with each other.
In addition, in consideration of workability and workability in connection work on site, a part of the web may be deleted at the same time as the upper flange portion.

不利となることはない。In a conventional beam-to-column joint using a metal joint, the upper and lower projecting portions are usually the same length, but the upper projecting portion is shorter than the lower projecting portion, so that the beam steel beam is formed. Can be reduced in size and processing can be facilitated. Also in this case, since the upper protrusion and the upper flange are joined via the splice plate, there is no particular disadvantage in the strength of the joint.

のとなる。[0010] The beam-column joint of the present invention is mainly designed to be joined only by bolt joints using high-strength bolts. A flange for joining by joining,
Such as a split tee having a web as a protrusion,
Using a pair of upper and lower T-shaped joints, the lower flange of the beam steel is placed on the web of the lower T-shaped joint, and these are joined by high-strength bolt friction joining to form the upper T-shaped joint. The web and the upper flange of the beam steel are sandwiched from above and below by a splice plate and joined by high-strength bolt friction welding.

Also, the joining between the joining hardware and the beam steel frame need not necessarily be limited to the high-strength bolt friction joining. Further, as for the form of the metal joint, various shapes other than the T-shaped metal joint are possible, and for example, a U-shaped metal joint in which upper and lower projecting portions are integrated is also possible.
