Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a structure for attaching and supporting a brace to a steel panel formed into a substantially rectangular shape.

(Prior art and problems) As a structure in which a vertical frame and upper and lower frames made of shaped steel are formed into a substantially rectangular shape, and braces are stretched between the inner corners, for example, the partially omitted perspective view of Fig. 4 is used. As shown in the figure, a gusset plate 30 is attached to the inner corner C formed by the vertical frame 10 and the lower frame 20 of the channel-shaped steel material,
As shown in the partially omitted perspective view of FIG. 5, a pair of gusset plates 30, 30, and fix the mounting plate 50 in a state perpendicular between the two gusset plates 30, 30.
There is a method of fixing the end of the brace 40 to 0.

However, in the former case, since the vertical frame 10 and the upper and lower frames 20 are made of channel-shaped shaped steel, the gusset plate 30 cannot be placed at the center in the in-plane direction of the panel. Therefore, the tension applied to the brace 40 is uneven, and the steel panel formed by the vertical frame 10, upper and lower frames 20, etc. is twisted in the plane.

On the other hand, in the latter case, both gusset plates 3
Since the mounting plate 50 is provided between the gusset plate 3
It is difficult to fix the mounting plate 50 so that the angles are substantially orthogonal to each other. Furthermore, the mounting plate 50 must be installed at a predetermined vertical angle between the gusset plates 30 and 30 in accordance with the respective lengths of the vertical frame 10 and the upper and lower frames 20, and the number of parts is not limited to a length that is difficult to install. This is causing problems such as an increase in

(Means for solving the problem) The present invention was devised to solve the above problem, and consists of a board with a support plate set up approximately in the center, and an inner corner formed by the vertical frame and the upper and lower frames. The support plate is fixed to the end of the brace, and the support plate and the mounting plate fixed to the end of the brace are fixed to each other, and the brace bears tension evenly and provides a mounting support structure that exhibits a sufficient bracing function in terms of strength. It is.

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

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

The mounting support structure of the present invention is provided at an inside corner formed with the opening 11 of the vertical frame 1 and the opening 21 of the lower frame 2 of the shaped steel material on the inside corner, and is installed between the diagonally opposite inside corners. A brace is placed in place as described below. The steel panel is normally erected by screwing the base plate 3 onto the anchor bolts on the foundation with nuts (none of which are shown). A reinforcing plate 4 is welded to this inside corner C (the figure shows the structure at one inside corner). The reinforcing plate 4 has a support plate 42 erected approximately in the vertical center of the substrate 41, and a pair of side edges 43, 43 on the opposite side from the support plate 42, forming a substantially square shape when viewed from two planes. An upper side 44 is fixed to the upper part.

The reinforcing plate 4 having such a structure has its side 4
3, 43 towards the vertical frame 1, and
It is stored in the opening 21 of the lower frame 2, and the side sides 43, 43 and the upper side 44 are welded to the vertical frame 1 and the upper and lower frames 2, respectively. Then, the support plate 42 itself is placed approximately at the center of the vertical frame 1 and the upper and lower frames 2. Next, the bolt hole h provided in the support plate 42 is aligned with the bolt hole h of the mounting plate 6 fixed to one end of the steel rod brace 5, and fixed with a high tension bolt B.

That is, by means of the reinforcing plate 4 provided at the inside corner C of the steel panel, the brace 5 is fixed at the in-plane center of the panel, and also on the side edges 43, 43 and the upper edge 44.
By integrally welding the vertical frame 1 and the upper and lower frames 2, a structure with a large stiffening effect is achieved.

FIG. 3 is a perspective view showing another embodiment of the reinforcing plate 4. FIG. In the reinforcing plate 4, the upper side 4
4 is provided on the same side as the support plate 42 and is welded to the support plate 42, thereby improving the stiffening effect of the support plate 42 itself.

(Effects) In the brace mounting support structure having the above configuration, the reinforcing plate is welded with its sides housed within the openings of the upper frame or lower frame, so it is always placed in the center of the steel panel. Therefore, the tension on the brace will not be eccentric. Therefore, no twisting or the like is imparted to the steel panel, and stress propagation becomes simple.

The brace can be fixed by fastening the mounting plate and the support plate with high tension bolts. Therefore, even if the length of the vertical frame, upper and lower frames, or the shape of the so-called steel panel changes, the position of the reinforcing plate will remain the same. ,
Workability is further improved as there is no need to change the shape.
