Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a column-beam joint fitting for a housing unit constructed by connecting a plurality of columns and casings, and a method for manufacturing the same.

BACKGROUND TECHNOLOGY In recent years, a construction method has been adopted in which multiple types of housing units are manufactured in advance at a factory and transported to a construction site, where they are combined to construct a housing.

Normally, a housing unit is constructed by interconnecting the upper and lower ends of four pillars placed at the four corners with four wires each to form a box-shaped frame, which is supplemented with interior and exterior walls, screw panels, and ceiling panels. It is constructed by attaching floor panels and the like.

By the way, the connection between the pillars and the beams that make up the framework of this type of housing unit can be achieved by, for example, welding the beams directly to the pillars, as shown in Japanese Utility Model Publication No. 16402/1982,
Alternatively, a method has been adopted in which a beam is welded to a column via a joint made of C-channel material.

In other words, in the direct welding method, as shown in FIG.
02 ends are directly welded. The scallop 102 is made of C-channel material, and horizontal flanges 102B are integrally formed on the top and bottom of a vertical web 102A. Pillar 10
1 includes an end diaphragm 103 for strength reinforcement.
and the inner diaphragm 104 are welded to each other.

However, the diaphragm 103.10 to the column 101
Welding No. 4, especially the welding of the inner diaphragm 104, must be performed inside the narrow column 101 and at a position a certain distance inward from the end, which is extremely difficult and difficult work. .

Therefore, as a method to eliminate the welding work of the diaphragm, C
A method of welding through a joint made of channel material has been proposed. As shown in FIG.
A shikichi member 107 made of C channel material having a width approximately equal to the width of the side surface of the pillar 106 and having a tip portion narrower than this is welded to one side of the pillar 106. It has a structure in which the wire 108 is welded to the top.

[Problem to be solved by the invention 2 By the way, the structure shown in FIG.
Since the diaphragm is welded with a wide width to the 06, there is no problem in terms of strength even if the diaphragm is omitted when the load is light. However, if the casing 108 is subjected to a heavy load, there is a problem in that sufficient strength cannot necessarily be ensured without a diaphragm.

SUMMARY OF THE INVENTION An object of the present invention is to provide a column-beam connecting fitting for a housing unit that can eliminate the need for welding work within the column and can connect the column and the column to sufficiently withstand heavy loads.

Another object of the present invention is to provide a manufacturing method that can manufacture the above-mentioned beam-column joint at low cost and with high precision, and can also manufacture a structure with higher rigidity.

[Means for Solving the Problems] Therefore, the column-beam joint fitting of the present invention can be used to connect a column-beam joint in a housing unit that includes a plurality of columns and a plurality of beams connected between the ends of these columns. A joining metal fitting has an L-shaped metal fitting body having two orthogonal vertical walls, and is fixed to the upper and lower end surfaces of the metal fitting body in parallel to each other,
A pair of end face members that form a pair of beam connecting parts to which a pillar can be connected to the outer surface of one side, and a pole can be connected together with the tip of each vertical wall of the metal fitting body; The present invention is characterized in that it includes an auxiliary member that is fixed to the open corners of the two vertical walls of the metal fitting main body and has an angular cross section that forms a substantially rectangular tube shape together with the two vertical walls.

Here, the metal fitting body may be, for example, one formed by bending a plate material into an L-shape to form two orthogonal vertical walls, or one formed from a mold. Similarly, for the auxiliary member having a cross-sectional shape, it is also possible to use, for example, a plate material bent at right angles to form a cross-sectional shape, or an L-shaped steel cut into a predetermined length. . Further, fixing is not necessarily limited to welding, and may be any method as long as both can be firmly fixed.

Further, the method for manufacturing a column-beam joint fitting of the present invention is a method for manufacturing a column-beam joint fitting in a housing unit that includes a plurality of columns and a plurality of beams connected between the ends of these columns. Then, a plate material is bent into an L shape to form a metal fitting body having two orthogonal vertical walls, and a pillar can be connected to the upper and lower end surfaces of this metal fitting body, and a pillar can be connected to one outer surface of the metal fitting body. A pair of end members forming a pair of threaded joints to which a beam can be connected together with the tips of each vertical wall are welded in parallel to each other, and the two vertical wall corners of the metal fitting body are opened between the pair of end members. It is characterized in that an auxiliary member having an angular cross section and forming a substantially rectangular tube shape together with the two vertical walls is welded to the side.

[For production]

In the column-beam joining metal fitting of the present invention, the two vertical walls of the metal fitting body and the auxiliary member are formed in the shape of a rectangular tube, and the end face members corresponding to the upper and lower surfaces of the metal fitting or the conventional tire flam play the role. It is possible to connect the pillars and the rice bowls to be able to withstand heavy loads. Moreover, the conventional welding work within the pillar can be eliminated.

Furthermore, in the manufacturing method of the present invention, the metal fitting body is formed by bending the plate material into an L-shape to form the metal fitting body having two orthogonal vertical walls. It can be manufactured at a lower cost and with higher precision than when molding from a mold.

In addition, a pillar can be connected to the upper and lower end surfaces of the metal fitting main body, and a pillar can be connected to the outer surface of one side of the metal fitting body, and a pair of end face members are provided that form a pair of threaded connection parts to which beams can be connected together with the tip of each vertical wall of the metal fitting main body. An auxiliary member is welded parallel to each other and has an angular cross section and forms a substantially rectangular tube shape together with the two vertical walls between the pair of end face members and on the open side of the two vertical wall corners of the metal fitting body. Since the column-beam joint fittings are manufactured by welding, in other words, all the members are welded into an integral structure, it is possible to form a structure with higher rigidity.
