Description

Description: TECHNICAL FIELD The present invention relates to a joint member for a pillar and a beam in a housing unit formed by connecting a plurality of pillars and a beam.

[Background technology]

In recent years, industrialized houses are known in which a plurality of housing units formed in a box shape or the like are stacked to construct a house.
The frame of this housing unit is formed by connecting a plurality of columns and beams. The connection between these columns and beams is, for example,
As shown in Japanese Utility Model Publication No. 59-16402, it is carried out by welding directly, or by welding through a joint made of C channel material.

That is, in the case of direct welding, as shown in FIG. 8, the beams 102 are welded to the adjacent side surfaces at the ends of the columns 101, respectively. These beams 102 are made of C-channel material, and flanges 102B are integrally formed on the upper and lower sides of a web 102A arranged in the vertical direction. An end diaphragm 103 and an inner diaphragm 104 for reinforcing strength are respectively welded to the columns 101 of the portions to which the flanges 102B are welded.

However, the welding of the diaphragms 103 and 104, particularly the inner diaphragm 104, to the pillar 101 is performed inside the narrow pillar 101 and at a position that is inward from the end to some extent, so that the workability is extremely poor and difficult work is performed. Met.

For this reason, as shown in FIG. 9, one side surface of the pillar 106 has a width at the base end portion that is substantially equal to the width of the side surface of the pillar 106,
A structure has been proposed in which a diaphragm is omitted by welding a joint member 107 made of a C channel material having a width narrower than that of the tip portion and welding a beam 108 to the joint member 107.

[Problems to be Solved by the Invention]

In the structure shown in FIG. 9, the connecting member 107 is the pillar 106.
Since it is welded over a wide width, the diaphragm is certainly not necessary for light loads. However, when the beam 108 receives a heavy load, there is a problem that sufficient strength cannot be secured without the diaphragm.

An object of the present invention is to provide a joining member which can be easily connected to a column and a beam, which can be easily welded and can withstand a heavy load.

[Means for solving the problem]

The present invention, a housing unit is formed by a plurality of pillars and a plurality of beams spanned between the end portions of these pillars, a joint member between the pillar and the beam in this housing unit,
A member having a U-shaped vertical cross section is bent into a substantially L-shaped plane with the open side of the U-shaped inside, and a column can be connected to the horizontal outer surface of this bent portion, and the U-shaped A flat cross-section L forming a substantially prismatic shape with a joining member main body having a beam connectable to each end and an open side of the bending portion of the joining member main body and a vertical outer wall of the bending portion. It is a joint member of a pillar and a beam in a housing unit, characterized by comprising a character-shaped auxiliary member.

In the present invention, a shape in which a member having a U-shaped vertical cross-section in the joining member body is bent into a substantially L-shaped plane with the open side of the U-shaped inside is not necessarily meant to be actually bent, It suffices if the shape is almost L-shaped. Therefore, for example, the joining member body may be manufactured by welding a pair of partial members, or may be integrally formed by casting or the like.

[Action]

In the present invention, since the column is connected to the horizontal outer surface of the bent portion of the joining member body, this horizontal outer surface serves as a diaphragm and can sufficiently bear a heavy load. Further, the auxiliary member welded to the open side of the bent portion of the joining member main body has a substantially prismatic shape with the vertical outer wall of the bent portion of the joining member main body, and should be regarded as an extension of the pillar. The horizontal outer surface of the bent portion of the joining member body functions as a diaphragm.

Since the welding work is performed from the outside for both the joining member main body and the auxiliary member, and the joining member main body and the pillars and beams, they can be performed very easily.

3B has a shape in which one end, that is, the base end side is obliquely cut at an angle of 45 degrees with respect to the width direction from a wide width almost equal to the width of the flange of the C channel material that is the material, and the other end, that is, the tip end side. The width is narrower than this width and is cut at an angle of 290 degrees with respect to the width direction. At this time, the width of the material on the base end side is made substantially equal to the width of the prismatic column 31, and therefore the width along the obliquely cut surface of the flanges 12B, 13B is the length of the diagonal line of the column 31. Are almost equal.

Each of the partial members 12 and 13 has a base end side welded to each other to form a joint member body 11. Therefore, both parts
The vertical outer wall 11A of the bent portion 14 of the joining member main body 11 is constituted by the webs 12A and 13A of 12, 13 so as to form two right angles. Further, the upper and lower horizontal outer surfaces 11B of the joining member body 11 are constituted by the flanges 12B and 13B of the two partial members 12 and 13.
