Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a panel frame that facilitates fitting of corner portions of the panel frame and improves work efficiency.

[Conventional technology and its problems]

When assembling frames of various panels such as floor panels, roof panels, exterior wall panels, etc. using steel materials, the edges of the frame materials are processed as shown in FIG. In other words, one end of the frame material having a U-shaped cross section that intersects and butts is drawn inward only in the portion where the end of the other side frame material overlaps, and only in that plate thickness, and this drawn portion is used to draw the other side. When the ends of the frame members are externally fitted, the surfaces of both frame members that are butted against each other are made to be flush. When drawing the end of one frame material in this way, in order to butt and overlap the other frame material, arrange the two frame materials at right angles, and draw one frame material horizontally in the direction of the arrow in Figure 3. It is necessary to move it to fit. Therefore, it takes time and effort to fit the drawn portion during frame work.

[Means for solving problems]

A frame material is made by cutting a U-shaped steel to a certain size, and at this end, the vertically opposing ends of the piece are cut at 45 degrees, and this is squeezed inward to form a triangular overlapping part. Arrange the frame members so that they are vertically symmetrical, butt each other at 45 degrees, and place the other frame over the end of one member so that the ends of the other frame overlap each other at the triangular overlapping part. Temporarily assemble by dropping the edges of the materials and fixing the overlapping parts to form a panel frame.

〔Example〕

The present invention will be explained below based on embodiments shown in the drawings.

In the figure, A and B are frame members made of U-shaped steel that have the length, size, and strength necessary to assemble the desired panel frame. They are cut to the required length in advance, and only the length differs. This frame material A is a shaped steel with a U-shaped cross section, with an upper piece 1 and a lower piece 2 arranged vertically opposite each other, and a side piece 3 connecting the upper and lower pieces 1 and 2, and is cut to a predetermined size.
The end of the upper piece 1 is connected to the other frame member B as shown in the figure.
Only the plate thickness of the upper end 14 of the upper piece 8 is narrowed inward to form an overlapping piece 4, and a step 5 is installed between this overlapping piece 4 and the upper piece 1.
form. Edge 6 of side piece 3 and lower end 7 of bottom piece 2
The shape remains the same as that of a shaped steel cut at right angles to a fixed size.

The other frame material B has the upper and lower pieces reversed from the frame material A, and the upper piece 8 and the lower piece 9 are bent and connected at the upper and lower parts of the side piece 10, and are arranged opposite to each other. The ends of are squeezed inward to form an overlapping part 11,
A step 12 is formed between this overlapping portion 11 and the lower piece 9.

Moreover, the overlapping part 4 of this frame material A is cut diagonally so as to connect the outer edge 1a of the upper piece 1 and the bent part 6a of the edge 6 of the side piece 3 connected to the upper piece 1. 45
It is cut into triangular shapes. Similarly, the overlapping part 11 of the frame material B is also
45 so as to connect the bent portion 13a of the edge 13 of the
It is cut into triangular shapes. Then, as shown in Figure 1, frame material A is installed on a framing jig (not shown), and then the other frame material B is placed from above in the direction that intersects with frame material A. By dropping the frame material A, the overlapping part 11 of the frame material B is superimposed on the lower end part 7 of the lower piece 2 of the frame material A, and the upper end part 14 of the upper piece 8 of the frame material B is placed on the overlapping part 4 of the frame material A. They are superimposed, and both frame members A and B are temporarily assembled at a required angle. Thereafter, the angle is adjusted and the overlapping portion is fixed by spot welding or the like.

During this temporary assembly, the overlapping parts 4 and 11 of both frame materials A and B have a triangular shape with the outer edges cut at 45 degrees, so even if one frame material is dropped, it will not collide with each other and it will be accurate. It can be assembled.

〔Effect of the invention〕

In the panel frame of the present invention, the ends of the frame materials that are butted against each other are vertically symmetrical, and the overlapping part is in a triangular shape with an angle of 45 degrees, and the panel frame is narrowed down by the thickness of the panel, so one frame material can be set in the frame jig. However, temporary assembly can be easily performed by simply dropping the other frame material from above, which has the advantage of shortening the frame work time and improving productivity.
