Description

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

[Background technology]

In recent years, a construction method has been adopted in which a plurality of housing units manufactured in advance at a factory are transported to a construction site and then assembled there to construct a housing. Typically, housing units are
The upper and lower ends of the four pillars placed at the four corners are interconnected using four beams each to form a box-shaped frame, and inside and outside wall panels, ceiling panels, floor panels, etc. are attached to this box-shaped frame. Installed and configured.

By the way, the connection between the columns and beams that make up the framework of this type of housing unit can be achieved by directly welding the beams to the columns, as shown in Japanese Utility Model Publication No. 59-16402, for example.
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 rice cake 102 is made of C-channel material, and horizontal flanges 102B are integrally formed above and below a vertical web 102A. Pillar 10
1 includes an end diaphragm 103 for strength reinforcement.
and 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 that is somewhat inward from the end, which is extremely difficult and difficult work. .

Therefore, as a method for eliminating diaphragm welding work,
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]

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, there is a problem in that when the casing 108 is subjected to a heavy load, sufficient strength cannot necessarily be ensured without the diaphragm.

SUMMARY OF THE INVENTION An object of the present invention is to provide a column-to-beam joint in a housing unit that can eliminate the need for welding inside the columns and connect columns and beams that can 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 to solve the problem]

The column-beam joint fitting for a housing unit according to the present invention is a column-beam joint fitting for a housing unit that includes a plurality of columns and a plurality of beams connected between the ends of these columns, A metal fitting body having the same planar cross-sectional shape as the pillar and shorter than the pillar, and fixed to the upper and lower end surfaces of the metal fitting body in parallel to each other, and the end of the pillar is joined to one surface. a pair of upper and lower end members, and a pair of side members that are fixed between two 90-degree side edges of these end members, and whose tips form a connecting portion of the katane together with the tip of the metal fitting main body. It is characterized by being composed of.

Here, the metal fitting body may be made by cutting the material of the pillar into short pieces, or may be made from a material different from that of the pillar.

Furthermore, the pair of end members and the pair of side members may be made by punching sheet metal using a press machine, or may be made by other methods, such as casting. Furthermore, the fitting body and the end member may be fixed together, and the end member and the side member may be fixed together by welding, or by other methods such as tightening with bolts or nuts.

A method for manufacturing a column-beam joint fitting for a housing unit according to the present invention is a method for manufacturing a column-beam joint fitting for a housing unit that includes a plurality of columns and a plurality of beams connected between the ends of these columns. A method for manufacturing a pair of upper and lower ends in which an end of the pillar is joined to one surface of the upper and lower end surfaces of a metal fitting main body that has the same planar cross-sectional shape as the pillar and is shorter than the pillar. The end members are welded in parallel to each other, and then a pair of side members whose tips form a connection portion of the wire with the tip of the metal fitting body are placed between the two side edges of these end members forming a 90 degree angle. It is characterized by being welded.

[Effect]

In the column-beam joint fitting according to the present invention, the pair of end members plays the role of a conventional diaphragm, and therefore,
Columns and beams can be connected to each other to withstand heavy loads.

In addition, since the pair of end members are also connected by the pair of side members forming an angle of 90 degrees, the column-beam joint has a box shape with sufficiently high strength.

In addition, in the method for manufacturing a column-beam joint fitting according to the present invention, the pair of end face members that serve as diaphragms are welded to the upper and lower ends, which are the outer surfaces of the fitting body, and therefore the troublesome work of welding the diaphragm to the inside of the column is required. There is no need to do this. In addition, since the end members and side members may be plate-shaped, they can be obtained with high precision by punching sheet metal with a press machine, making it easy to manufacture them, and making it possible to weld the fitting body, end members, and side members together. Since the column-beam joint metal fittings can be produced with just one step, the manufacturing work for the column-beam joint metal fittings can also be simplified.
