Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a joining structure of members orthogonal to each other, and preferably relates to a joining structure of an upper frame and a metal frame of a metal fitting.
[0002]
[Prior art]
Conventionally, in metal fittings, there are a side pin method and a guide plate method for attaching the upper frame and the eaves frame. FIG. 12A is a schematic perspective view showing a side pin system, in which a pin b extending in the horizontal direction is provided at the end of the upper frame a, and the pin b is received in a side portion of the collar frame c. A receiving hole d is formed. The pin b is inserted into the receiving hole d, and a set screw f is screwed into the fixing tap hole e. However, the stainless steel member forming the frame body has a limit in the accuracy of the distance between the pitches of the holes in the saddle frame in which the bending is performed in the middle due to the property that the bending process is performed after drilling or the like is performed. . Therefore, it is necessary to make the diameters of the receiving hole and the tap hole formed in the upper frame larger than the diameters of the guide pin and the set screw. As a result, when assembling the eaves frame and the upper frame, the clearance between the hole and the guide pin is generated in the horizontal and vertical directions. Therefore, the upper frame and the eaves frame are adjusted to the appropriate positions and joined. There was a drawback that it took time and effort.
[0003]
FIG. 12B is a schematic perspective view showing a guide plate system. The guide plate method has an advantage that there is no adjustment work in the assembly because it is a method of joining the collar frame c to which the guide plate g matched to the inner dimension of the upper frame a and the upper frame a are joined. However, if the mounting position of the guide plate is not accurate, there is no means for adjusting and it is necessary to remanufacture. In addition, stainless steel members are designed to make the bending corner portion h sharp, so the V-groove processing i is performed on the bending corner portion h, so when an excessive force is applied to the joined members during assembly work. There is a concern that the side plate portion directly hits the bending corner portion of the upper frame, so that the bending corner portion is cracked.
[0004]
[Problems to be solved by the invention]

Another object of the present invention is to provide a joining member that can be easily dimensionally adjusted in the field even when the mounting accuracy is poor in the joining structure of members orthogonal to each other.
[0005]
[Means for Solving the Problems]
The technical means employed by the present invention in order to achieve such a problem is a joining structure of long members orthogonal to each other, wherein one long member has a first joining member and the other long member has a first joining member. Two joining members are respectively attached, and the first joining member has a front wall, left and right vertical pieces extending perpendicularly to the front wall from the front wall, and perpendicular to the front wall from the front wall. A horizontal piece extending horizontally, and the second joining member is formed in a substantially U shape in a side view from the front wall, the upper surface wall, and the lower surface wall, and the upper surface wall or the front wall or A first receiving part for receiving the horizontal piece of the first joining member is formed on the lower surface wall, and a second receiving part for receiving the left and right vertical pieces of the first joining member in the left-right direction of the front wall. Are formed, and the horizontal pieces are engaged with the first receiving portion, and the left and right vertical pieces are engaged with the first piece. The first joining member and the second joining member are polymerized so as to be engaged with the receiving portion, and the first joining member and the second joining member are fixed in this state. It is characterized by.
[0006]
Since the joining structure according to the present invention is configured as described above, the horizontal positioning is handled by the horizontal piece of the first joining member and the first receiving portion of the second joining member, and the vertical positioning is the first. The left and right vertical pieces of the one joining member and the second receiving portion of the second joining member take charge. The external force in the horizontal direction is also handled by the horizontal piece of the first joining member and the first receiving portion of the second joining member, and the external force in the vertical direction is the left and right vertical pieces of the first joining member and the second joining member. The second receiving part of will be in charge.
[0007]
According to the present invention, the horizontal positioning can be performed by the end edges of the horizontal piece extending in the left-right front-rear direction coming into contact with the end edges extending in the left-right front-rear direction of the first receiving portion. it can. The vertical positioning is performed by engaging the vertical piece with the second receiving portion independently of the horizontal positioning. Since the positioning is determined by the notch dimensional accuracy of the part, the dimensional accuracy can be easily obtained at the notch, so that assembly without backlash is possible.
[0008]
Preferably, the horizontal piece and the vertical piece are configured such that only a distal end portion in the extending direction is engaged with the first receiving portion and the second receiving portion. The tip part means, for example, a part about half of the extension dimension. By configuring so that only the tip portion engages with the receiving portion, the tip portion can be polished with a sander or the like, so that dimension adjustment can be easily performed on site.
