Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a column-beam joint portion of a residential unit for connecting and joining a column and a beam.

[0002]

2. Description of the Related Art In recent years, when building a house or the like, a housing unit in which columns and beams are joined in a predetermined shape has been widely used. This residential unit is pre-manufactured in a factory, transferred to a construction site, assembled and used. In the housing unit, the pillar and the beam are generally joined by, for example, an inner diaphragm method or a through diaphragm method.

In the inner diaphragm system, a joint fitting is provided at a predetermined position of a column, and the end of a beam made of a channel material is joined to the joint fitting. A diaphragm for reinforcement is provided by welding in a column on the extension of the joint fitting. However, since the inside of the column is narrow, the work of welding the diaphragm is difficult and there is a problem in workability. In addition, if the diaphragm is not mounted on the exact extension of the joint fitting, the force applied to the column may not be efficiently dispersed in the beam, and the reinforcing effect may be weakened. Further, the number of parts required for joining is large and the process is complicated, resulting in high cost.

Further, in the through diaphragm system,
This is a method in which the pillar is divided at the mounting position of the beam, a joint fitting having a diaphragm portion is attached to the end of the pillar, and the end of the beam is connected to the joint fitting. In this through diaphragm method, it is not necessary to weld the diaphragm inside the column, and since the beam and the diaphragm are directly connected, the strength is high. On the other hand, it is difficult to attach the column and the diaphragm portion with high precision, and the inconvenience caused by this is inevitable.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and can not only firmly connect a column and a beam, but also has a small number of parts and a simple structure. Moreover, it is an object of the present invention to provide a column-beam joint structure of a residential unit that is easy to process and extremely economical.

[0006]

[Means for Solving the Problems] That is, the present invention is
In the structure of a column-beam joint of a residential unit in which the ends of the column are joined to the outer surface of the upper flange or the outer surface of the lower flange of the beam made of channel material, between the upper flange and the lower flange of the beam, a central surface and A reinforcing metal fitting having a substantially U-shaped cross section, which is composed of side surfaces formed at both ends thereof, is constructed such that the side surfaces are in a vertical direction and the upper and lower ends thereof contact the inner surface of the upper flange and the inner surface of the lower flange of the beam, and The structure of a beam-column joint portion of a residential unit, wherein the surface is fixed so as to be located at the opening surface of the beam facing the vertical surface of the beam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of a housing unit having the structure of the present invention, FIG. 2 is a sectional view of an essential part thereof, FIG. 3 is an exploded perspective view of the essential part, and FIG. 4 is another example of the present invention. A sectional view and FIG. 5 are exploded perspective views thereof.

As shown in FIG. 1, the present invention is to join a plurality of beams 11 and columns 21 firmly and easily and easily to form a predetermined housing unit.
The beam 11 is made of a suitable channel material in which an upper flange 13 and a lower flange 14 are formed at both ends of a vertical surface 12. The end of the column 21 is joined to the outer surface of the upper flange 13 or the outer surface of the lower flange 14 of the beam 11 by welding. 2 and 3, the joint J1 at the lower corner C of the housing unit configured by joining the ends of the beams 11 and 11a shown by the circle A in FIG. 1 is shown, and the pillar 21 is It is fixed to the upper flange 13 of the beam 11. A suitable square steel or the like is used for the pillar 21. In FIG. 1, reference numeral 25 is a positioning pin, and 26 is a fixing hole for fixing the units on the upper floor and the lower floor in the correct positions when the residential units are stacked and used.

At the joint J1 between the column 21 and the beam 11, reinforcing metal fittings 15 are arranged between the upper and lower flanges 13 and 14 of the beam 11. As shown in FIGS. 2 and 3, the reinforcing metal member 15 is for forming a diaphragm inside the beam 11 to reinforce the joint J1.
The central surface 16 and the side surfaces 17 and 18 formed at both ends of the central surface 16 are formed into a substantially U-shaped cross section. The heights of the central surface 16 and the side surfaces 17 and 18 are equal to the distance between the upper flange 13 and the lower flange 14 from the side surfaces 17 and 1.
The length of 8 is the upper flange 13 and the lower flange 1
The depths of 4 are almost equal to each other. The reinforcing metal fitting 15 is arranged and fixed such that its side surfaces 17 and 18 are in the vertical direction and the central surface 16 is located at the opening surface 19 of the beam formed by the upper flange 13 and the lower flange 14. To be done.

As a result, the ends of the side surfaces 17, 18 are in contact with the inner surfaces of the upper and lower flanges 13, 14 and the side surfaces 17, 18,
The tip of 18 abuts the inner surface of the vertical surface 12 of the beam 11. Then, the central surface 16 of the reinforcing metal fitting 15 has the upper and lower flanges 1.
The diaphragm is formed by the reinforcing metal fitting 15 and the beam 11 in contact with the end portions of the wires 3, 14. The beam 11 and the reinforcing metal member 15 are fixed to each other by welding or the like, and the joint J1 is strongly reinforced. Another beam 1 constituting the lower corner portion C
The beam 1a is fixed to the central surface 16 of the reinforcing metal member 15 with bolts 20 and the like, but the beam 11a can also be fixed by welding.

According to this structure, the diaphragm structure can be formed only by fixing the reinforcing metal fitting having a U-shaped cross section to the joint between the column and the beam. Therefore, the pillar and the beam can be firmly joined. In addition, the number of parts and man-hours of the joining portion are reduced, the weight of the housing unit can be reduced, and the joining work is extremely efficient and economical. Moreover, since the shape of the parts is simple, processing is easy.

4 and 5 show another example of the present invention indicated by a circle B in FIG. 1, in which a column 21 is joined to a portion other than the end of the beam 11 of the residential unit. . Reference numeral J2 is a joint. The reinforcing metal fitting 15 has its side surfaces 17 and 18 in the vertical direction, and the central surface 16 has the beam 11
It is attached so as to be located on the opening surface 19 of the. The side surface end portion of the reinforcing metal member 15 is fixed by contacting with the inner surface of each of the upper flange 13 and the lower flange 14 by welding.

[0013]

As shown and described above, according to the present invention, a diaphragm having high strength can be easily formed at the joint between the beam and the column. Further, since the diaphragm structure of the joint portion is a simple structure and has a small number of parts, the joint work becomes easy and efficient and economical, and the housing unit can be lightened. Further, since the shape of the parts is also simple, processing is easy.
