To lock. Further, in the case where the sub-engagement portions 2c, 2c are formed on the mounting main plate 2, the pressing engagement portions 4, 4 of the clip B are configured to be sandwiched from both ends in the width direction of the mounting main plate 2 (first 3 figures,
(See FIG. 12).

[Effect of device]

According to the first aspect of the invention, the mounting main plates 2 and 2 are formed so as to project outward from the lower ends on both sides of the gate-shaped portion 1 which is long in the longitudinal direction.
A base material A having a locked portion 2b formed therein, and a clip B having pressure locking portions 4 and 4 capable of locking the locked portion 2b formed at both ends of the elastic C-shaped bent portion 3. First, the structural material 7 such as a cross beam is simply and quickly provided by using the base material made of
The base material A can be attached to the structural material 7 with a constant strength regardless of the second skill level.
The third effect is that it can be firmly fixed to, and thirdly, it can respond well to roof slopes and the like.

These effects will be described in detail. First, the mounting main plate 2 of the base material A with the bracket C is placed on the mounting surface 7a of the structural member 7, and the mounting main plate 2 and the mounting surface 7a are made of different materials. By sandwiching the clip B between the pressure locking portions 4 and 4,
The base material A can be fixed to the structural material 7. Therefore, there are many work processes in conventional welding work. Specifically, a welding machine is set at the site, the actual welding work is performed, and then the slag at the welding location is dropped, and the rust-preventive paint is applied there. There is a need for work procedures such as painting, welding work below 0 degrees Celsius or in the presence of wind, etc., because the welding strength will not be sufficient, and it will not be possible to work, and electric shock etc. on rainy days However, in the present invention, regardless of such weather conditions, this mounting work places the base material A with the receiving bracket C on the mounting surface 7a and attaches the clip B. The above-mentioned drawbacks are solved by being able to easily attach it only by engaging. Further, unlike the construction by means of fixing with fixing tools such as bolts and nuts, it is only by placing the clip B and inserting and locking it, and it can be actually performed in an instant.

Next, on both sides of the mounting main plate 2 of the base material A, the locked portions 2b,
2b is formed, and when the mounting main plate 2 and the mounting surface 7a of the structural member 7 are clamped by the clip B, the pressure locking portion 4 is locked to the locked portion 2b, and the clip B is It does not fall off easily, and the pressure locking parts 4, 4
Holds a predetermined gripping force by the elastic U-shaped bent portion 3, and the mounting strength between the mounting main plate 2 and the mounting surface 7a becomes constant. This can be realized by any worker. Yes, it is possible to always secure a constant mounting strength.

Further, the base material A of the present invention is also formed with the gate-shaped portion 1, so that not only can the structural member 7 such as a beam be reinforced, but also the height of the gate-shaped portion 1 can be changed. As a result, the height position of the receiving bracket C with respect to the structure becomes appropriate, and there is an advantage that an appropriate roof slope can be obtained.

Next, in the invention of claim 2, the sub-engagement portions 2c, 2c for preventing lateral shift are formed on both the mounting main plates 2 and 2 of the base material A in the invention of claim 1, and the upper half portion of the clip B is formed. Since it can be inserted between the sub-engaged portions 2c, 2c, when the clip B is locked, it is used for fixing the mounting main plate 2 of the base material A and the mounting surface 7a of the structural material 7 to each other. It is possible to make the clip B excellent in durability without dropping off. That is, the pressure locking portion 4 of the clip B, which sandwiches and secures the mounting main plate 2 and the mounting surface 7a, engages with the locked portion 2b of the mounting main plate 2, and the upper piece of the clip B has the sub locked portion. Since it is configured to be sandwiched between 2c and 2c, the clip B does not laterally shift, and consequently the clip B can be prevented from dropping from any direction.

The other structure is the same as that of the invention of claim 1, and the same effect as this can be exhibited.

Further, in the invention of claim 3, since the stoppers 2d, 2d are formed at the outer ends of both sides of the main mounting plates 2 and 2 of the base material A in the invention of claim 1, the base material A is formed.
By mounting the on the structural material 7, the positioning of the attachment to the structural material 7 can be easily performed, and accurate construction can be performed. This is because the stoppers 2d, 2d provided at the outer ends on both sides of the mounting main plate 2 sandwich the both end edge portions of the mounting surface 7a of the structural member 7 in a plan view, so that the base material A is placed on the mounting surface 7a. The mounting position can be accurately set at the same time as the mounting, and moreover, even when the mounting main plate 2 and the mounting surface 7a are sandwiched and fixed by the clip B, the stoppers 2d, 2d are planarized on both end edges of the mounting surface 7a. Since it is sandwiched, it can be installed accurately without shifting the position.

The other structure is the same as that of the invention of claim 1, and the same effect as this can be exhibited.
