Description

[Detailed description of the invention] (Technical field) The present invention is a brace provided between the inner corners of a steel panel formed into a substantially rectangular shape by vertical frame members, upper frame members, and lower frame members made of shaped steel. Regarding the mounting structure.

(Prior Art and Problems) A structure in which the vertical frame and the upper and lower frames are formed into a substantially rectangular shape and braces are stretched between the inner corners is shown, for example, in the partially omitted perspective view of Fig. 3. , an inner corner C formed by the vertical frame 10 and the lower frame 20 of the channel-shaped steel material
A method of welding a gusset plate 30 to the gusset plate 30 and fixing the end of the brace 40 directly to the gusset plate 30, or a method of welding a pair of gussets to the inside corner C as shown in the partially omitted perspective view of FIG. plate 30,3
0, and both gusset plates 30, 30
There is a method of fixing the mounting plate 50 in a state where the braces 40 are perpendicular to each other, and fixing the end of the brace 40 to the mounting plate 50. However, the former has a vertical frame of 10
Since the upper and lower frames 20 are formed from channel-shaped shaped steel, the gusset plate 30 cannot be placed at the center of the steel panel in the in-plane direction, and the tension applied to the brace 40 is biased. That is, the steel panel itself formed by the vertical frame 10 and the upper and lower frames 20 is twisted within its plane. In the latter case, since the mounting plate 50 is welded between both gusset plates 30, 30, the steel panel itself does not twist as in the former case, but the mounting plate 50 is welded approximately perpendicular to the gusset plates 30, 30. It is extremely difficult to weld 50. Furthermore, the mounting plate 50 must be mounted at a predetermined vertical angle corresponding to each length of the vertical frame 10 and the upper and lower frames 20, making the installation even more difficult. Further, problems such as an increase in the number of parts arise.

(Means for solving the problem) The present invention was devised to solve the above problem, and the side edges of the mounting plate are attached to the inner surfaces of both sides of the upper and lower frames made of channel-shaped steel. By welding and fixing the ends of the brace to this mounting plate, the brace bears the tensile force without deviation and provides a bracing mechanism with sufficient strength.

(Example) Hereinafter, the mounting structure of the brace of the present invention will be explained in detail based on the drawings.

FIG. 1 is a perspective view of parts constituting the mounting structure, and FIG. 2 is a partially omitted perspective view showing the mounting structure formed by the same parts.

The mounting structure of the present invention has an opening 1 in a vertical frame 1 of a shaped steel material.
1 and the opening 21 of the upper frame or lower frame 2 is provided at the inner corner C of the panel formed with the opening 21 on the inner corner side,
A brace is stretched between the diagonally opposite inner corners of the panel as described below. The vertical frame 1 and the upper and lower frames 2 are welded together at approximately right angles via a brace plate 3. That is, the right angle portions formed by the vertical frame 1 and the upper and lower frames 2 become inside corners C, C, . . . .

For example, the upper and lower frames 2, 2 have a bottom side 21 and both side sides 2.
It is a channel-shaped steel material having an opening 23 formed by 2 and 22. The mounting plate 5 fixed to the end of the brace 4 is accommodated and welded toward the base plate 3 from within this opening 23. That is, upper and lower frames 2,
The side edges 51, 5 of the mounting plate 5 are attached to the inner surfaces of both sides of 2.
1 are in contact with each other, and the mounting plate 5 itself is perpendicular to the side edges 22, 22, and the inner surface and the side edge 5 are in contact with each other.
1, 51 are welded. As described above, the mounting plate 5 may be fixed to the end of the brace 4 in advance, but it is stored in the opening 23 in advance with a predetermined inclination angle and welded, and then attached to the brace 4.
(The above figures show the welded state at one inside corner C).

As described above, the mounting plate 5 itself is attached to the upper and lower frames 2.
The brace 4 is welded into the opening 23 of the vertical frame 1 in a state perpendicular to the side edges 22, 22, and the end of the brace 4 is fixed approximately at the center of the mounting plate 5.
It is placed approximately at the center of the steel panel formed by the upper and lower frames 2. Furthermore, if the lateral dimension of the mounting plate 5 is set in advance in accordance with the lateral width of the opening 23, the perpendicular state of the side edges 22, 22 and the mounting plate 5 can be easily ensured, and welding can be performed extremely accurately.

(Effect) In the brace mounting structure with the above configuration, the mounting plate is always made of steel because it faces the base plate, which is the intersection of the vertical frame and the upper and lower frames, and is placed within the sides of the upper and lower frames. Since it is placed in the center of the panel surface, the tension applied to the brace does not shift, so the steel panel itself does not twist, stress propagation is simple, and welding accuracy and workability are further improved. .
