Particularly, it relates to improvement of the shear force transmission structure of the beam.

Description of the Related Art Conventionally, when joining a beam made of H-shaped steel to a concrete-filled steel tubular column, the joining structure shown in FIG. 8 (A) is generally adopted. That is, the pipe column 21 is cut at the flange height of the beam 22, and a reinforcing diaphragm 23 is welded to this cut portion so that the outer peripheral portion thereof projects outside the pipe wall, and the pipe column 21 is filled with concrete. To do. At the site, the flange end of the beam 22 is directly welded to the diaphragm 23.

いので、その手順も煩雑である。However, in the above structure, the beam 22 of the tube column 21 is used.
It is necessary to cut the joint part for joining the parts and weld the diaphragm 23 to the cut part, which complicates the structure. Further, since the filling of concrete must be performed over each space in the tube column 21 partitioned by the diaphragm 23, the procedure is also complicated.

Concrete 34 is filled in the pipe pillar 31, and the thick portion 3
We have developed a structure in which the beam 22 is joined by welding using 1a as a joint. In this case, the shearing force of the beam 22 acting on the Joint portion tubular column 31, the difference between the inner diameter d 2 of the inner diameter d 1 and the non-thick portion of the thick portion 31a of the tubular column 31 (d 2 -d 1) It is transmitted to the filling concrete 34 as a proportional bearing pressure.

る。However, in the structure in which the shearing force is transmitted by such an inner diameter difference, it is necessary to make the wall thickness of the thick portion 31a considerably large in order to allow the shearing force to be transmitted sufficiently. Originally, the plate thickness of the tube column 31 of the joint portion is determined by the magnitude of the bending moment of the beam 22, but in the above configuration,
In order to transmit such a shearing force, it is necessary to make the plate thickness of the joint portion thicker than the thickness required for the bending moment,
It becomes uneconomical. Although the plate thickness of the thick portion 31a is increased by high frequency heating, it is difficult to form the thick portion 31a that bulges only inward as shown in FIG. ), The inner diameter difference (d 2 −d 1 ) cannot be secured without sufficiently increasing the thickness of the thick portion 31a, which is further uneconomical.

かも接合品質も安定する。According to this structure, since the column is a concrete-filled tubular column, the bending force is mainly supported by the tubular column, and the axial force is mainly supported by the concrete. In this case, since the web of the beam inserted inside the tube column is embedded in the concrete, the shearing force of the beam acting on the joint portion of the column is directly transmitted to the concrete in the tube column. That is, the lower surface of the insertion portion of the web into the column is directly received by the concrete, and the shearing force is also transmitted to the concrete by the frictional force on both side surfaces of the insertion portion of the column. Therefore, the structure is mechanically clear and has a simple structure and excellent resistance to shearing force. Since the insertion portion of the beam into the pipe column extends in the vertical direction, there is no problem with the filling property of concrete. If the joint of the column is thick, a bearing pressure proportional to the difference in inner diameter between the thick and non-thick parts can be obtained, which further improves the proof stress against the shearing force acting on the beam. To do. When the beam is divided into the bracket and the beam body, the bracket can be joined to the pipe column in advance, and only the work of joining the beam body to the bracket can be performed on site. Therefore, the work of inserting the web of the beam into the slit can be performed in the factory, and the joining quality and workability can be improved. The beam is bolted to the peripheral wall of the pipe pillar through the joining metal fitting, and when one side bolt is used for the bolt joining to the pipe pillar of the joining metal fitting, in order to bolt the joining metal fitting to the pipe pillar, It is not necessary to put nuts in the tube column in advance or to screw them, and the joining work becomes easy. Also, unlike welding joining, large-scale equipment is not required, and brackets can be joined at the construction site by assembling, so that the pipe columns can be transported in the state of wire rods that do not project the brackets, and transport efficiency is good. Moreover, the joining quality is stable.

易となる。EFFECTS OF THE INVENTION The joint structure of a concrete-filled pipe column and a beam of the present invention is made of a shaped steel in which a beam insertion slit is provided along the longitudinal direction on the peripheral wall of a metal pipe column and the tip is joined to the pipe column. Since the web of the beam is inserted into the slit, the strength against the shearing force of the beam is improved, the structure is simple, and the filling property of concrete is not hindered.
In the case of the invention of claim 2, since the beam-joining joint portion of the tube column is a thick wall portion swelling on the inner surface or both inner and outer surfaces, the inner diameter of the thick wall portion and the non-thick wall portion at the lower end of the thick wall portion. The bearing pressure due to the difference is transmitted to the filled concrete, and the proof stress against the shearing force acting on the beam is further enhanced. In the case of the third aspect of the invention, since the beam is divided into the end bracket and the beam body, it is not necessary to insert the web at a high place on the site, and the workability at the site is improved. In the case of the invention of claim 4, since the beam and the pipe column are bolt-bonded to each other via the joint fitting, the bracket of the beam can be joined to the pipe column by grounding or the like, and the pipe column is transported as a wire rod. it can. Moreover, since the one side bolt is used as the bolt for joining the joining metal fitting to the pipe pillar, it is possible to join the fitting metal fitting to the pipe pillar without placing a nut in the pipe pillar in advance or cutting the screw, Joining work becomes easy.
