The mounting bracket has a structure in which the back surface of the hook-shaped notch at both ends of the gripping body is in contact with the bent end portion (tip of the rising portion) of the temporary enclosing plate. However, the temporary enclosing plate tends to have a large variation in the size of the rising portion due to its manufacture. For this reason, when mounting here, there is a problem that the precision of the width dimension of the temporary enclosing plate is required to be high.

Further, since the bent end portion (tip of the rising portion) of the temporary enclosing plate and the hook-shaped notch portion of the gripping body contact each other in a crossed state, that is, the bent end portion is formed in the vertical direction. Since the hook-shaped notch is in the horizontal direction, its contact area is small, and the hook is easily deformed when the fastening force of the mounting bracket is large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to fix a fixing bracket without being affected by a large variation in dimensions of an end portion (rising portion) of a temporary enclosing plate. Can be locked to the rising part of the temporary enclosing plate, and the entire bent end has a contact area with the temporary enclosing plate, so that it is difficult to deform even if the mounting bracket is strongly tightened. Provided are an assembled structure of a shroud plate and its mounting bracket.

That is, the present invention provides: (1) a mounting bracket having a substantially U-shape, a fixing bracket mounted at a central portion thereof, and both ends bent to form a U-shaped locking portion; And a plurality of temporary enclosing plates formed by bending both ends inward to form an abdomen with which the ends of the U-shaped engaging portions are in contact, and a support framework provided with a horizontal frame, and are provided side by side. A horizontal frame of the support frame is arranged on the temporary enclosing plate, and a mounting bracket is attached so as to straddle the horizontal frame, and the U-shaped locking portion is locked to the abdomen of the bent end portion of the temporary enclosing plate and fixed. A mounting structure for a temporary shroud made by pressing the horizontal frame against the support frame with metal fittings.

(2) Attaching the horizontal frame of the support frame assembly to a plurality of juxtaposed temporary enclosing plates having both ends bent inward to form an abdomen with which the ends of the U-shaped engaging portions are in contact. The mounting bracket has a substantially U-shape, a fixing bracket is mounted at the center thereof, and both ends are bent to form a U-shaped locking portion, and the mounting bracket is mounted so as to straddle the horizontal frame. A mounting bracket for the temporary enclosing plate, wherein a U-shaped engaging portion is attached to the abdomen of the bent end of the temporary enclosing plate, and the horizontal frame is pressed against the support frame by a fixing bracket.

[0008]

FIG. 1 shows an assembly structure of a temporary shroud. This structure is disposed at a construction site or a material storage area. A plurality of temporary enclosure plates 10 arranged in parallel are supported and fixed to a horizontal frame 20 a of a frame 20 by a mounting bracket (hook) 30.

FIG. 2 shows a cross-sectional view of the temporary enclosure. This temporary enclosing plate has both ends (rising ends) bent in the same direction, and one end 12 thereof has a bent portion shown in FIG.
12a, outward fold 12b, lateral fold 12
c, a bent portion 12d in the inward direction and a bent portion 12e in the inward direction (temporary enclosure plate direction) are sequentially formed. The other end portion 14 of the temporary enclosing plate includes a laterally bent portion 14a, an inwardly bent portion 14b, a laterally bent portion 14c, an inwardly bent portion 14d, and a further inward direction (shown in FIG. 2). ) Is sequentially formed.

FIG. 3 shows an enlarged view of a fixing portion with a mounting bracket. The temporary enclosures arranged side by side are combined with one end 12 of one temporary enclosure and the other end 14 of the other temporary enclosure in contact with each other, and a horizontal frame 20a is arranged at the bent portions 12d and 14d. The flat portion 16 is formed. The pair of mounting brackets 30 is
straddle a, and lock both ends to both ends of the temporary shroud,
The horizontal frame is attached and fixed to the temporary shroud with a fixture 40 such as a bolt.

The details of the mounting bracket will be described with reference to an enlarged view of FIG. In this mounting bracket, a belt-shaped bracket main body is bent into a U-shape, and a fixing member 40 is attached to a central portion thereof.
Twisting is applied at both sides by 90 degrees, and both ends are further bent into a U-shape to form locking portions 32,32. These locking parts 3
As shown in FIGS. 5 and 6, the front end surfaces of the second and second hooks 32 are locked to the back surface B of the inwardly bent portion 12d or 14d.

According to this configuration, the following effects are exhibited. That is, in the provisional enclosing plate, variations in the dimensions of the end portions (rising portions) 12 and 14 are likely to be large in manufacturing. However, according to this configuration, since the U-shaped bent ends 32, 32 of the mounting bracket are in contact with the rear surface abdomen B of the temporary enclosing plate, the influence of the processing dimensional accuracy of the temporary enclosing plate end (rising portion). I do not receive.

Further, U-shaped bent ends 32, 32 of the mounting bracket
Has a structure in contact with the back surface abdomen B of the temporary enclosing plate, so that the entire bent end portion has a contact area with the temporary enclosing plate. For this reason,
The contact area is large, and it is hard to be deformed even if it is strongly tightened with the fixture 40.

It should be noted that the present invention is not limited to the case in which two mounting brackets are mounted side by side as in the above-described embodiment. For example, as shown in FIG. 7, the bending direction of one U-shaped bent portion is Is changed, and the space between the one U-shaped bent portion and the other U-shaped bent portion is set to a predetermined distance, whereby the mounting can be performed using one mounting bracket. Further, as shown in FIG. 8, it is also possible to use a set of mounting brackets having this structure and use them in a crossed manner.

[0015]

According to the present invention, even if the end portion (rising portion) of the temporary enclosing plate has a large variation in dimension, both ends of the fixing bracket are connected to the rising portion of the temporary enclosing plate without being affected by the variation. Can be stopped. In addition, since the entire bent end portion has a contact area with the temporary enclosing plate, a remarkable effect such as being hardly deformed even when being strongly tightened is exhibited.
