Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention is mainly used for fixing C-type steel (lip groove type steel) installed laterally to a roof body, or for steel frame construction. Regarding fixings for C-shaped steel for building structures, which are used when fixing C-shaped steel that is erected laterally to a steel column erected on a concrete foundation, etc. to attach an external wall. l-ru.

``Prior Art'' Conventionally, a fixture for this scale has been used as shown in FIG. 7.

In other words, 1 is a steel column 2 erected on a concrete foundation.
This support piece 1 has a vertical part 1a attached to the outer wall 2a, and is bent in a direction perpendicular to the vertical part 1a and has a through hole 3 in the center. It consists of a horizontal part 1b having a horizontal part 1b.

Thus, the C type aA4 is installed on the horizontal part 1b of the support piece 1 so that its through hole 5 coincides with the through hole 3, and the bolt 6 is passed through the through hole 3.5 on both pages, and the washer 7 is inserted. Tighten the bolt 6 with a through hole h8 to fix the C-shaped steel 4 to the support piece 1. Then, an external wall material (not shown) is attached to the side wall portion 10 having the attachment hole 9 of the C-shaped steel using a suitable fixing tool.

However, the above fixture has the following drawbacks.

(2) The support piece 1 must be welded to the outer wall 2a of each steel column 2 so as to completely align with the through hole 5 of the C-shaped steel 4.

There was a problem in that if the through hole 3 of the support piece 1 and the through hole 5 of the C-shaped steel 4 did not match, the poles 1-6 could not be passed through the through hole 3.5.

■ When using the above fixture, it is necessary to form a plurality of through holes 5 for bolts in the C-shaped steel 4, and the precision of the formation position of the through holes 5 is required in relation to the meaning of (■) above. It was done.

(2) The C-shaped steel 4 must be installed on the support piece 1 so that its long groove or frontage always faces upward.

Therefore, there was a problem that dust remained on the C-shaped steel 4.

``Object of the present invention'' In view of the above-mentioned drawbacks of the conventional art, the present invention greatly simplifies the welding work of the mounting body in that there is no need to pay attention to the attachment point of the fixing device to the roof body or the outer wall of the steel column. In addition, it is easy to connect the support to the mounting body, and the C-shaped steel can be easily fixed to the support, and the C-shaped steel does not slide off the support. To obtain a fixing device for C-shaped steel for building structures, which eliminates the need to form through holes for bolts in the C-shaped steel and allows the C-shaped steel to be erected upside down to prevent dust from remaining on the C-shaped steel. be.

In the above configuration, the attachment body 16 is first welded to the outer wall 12 of the steel column 11. Next, the support rod 17 is hooked to the engaging portion 16b of the mounting body 1G. Next, the C-shaped steel 13 is attached to the support rod 1.
7 is temporarily supported by the support portion 17c. In this case, C-shaped steel 1
3 is horizontally installed on the support rod 17 so that the opening 13d faces downward. Next, the support head 19a of one support body is
It is fitted into the mold tA13, and the insertion hole 24 of the connecting leg portion 19b is aligned with the insertion hole 23 of the connecting portion of the attachment body 16. After that, tighten the bolts 1 into each insertion hole 24 and 23.
As shown in FIG. 1, the nut 18b is screwed onto the tightening bolt 18a through the bolt 8a, thereby integrally connecting the mounting body 16 and the support body 19. Therefore, when the support rod 17 is removed from the attachment body 16, the C-shape 113 is supported by the support body 19.

Next, the embodiment shown in FIGS. 4 to 6 will be explained.

In the description of this embodiment, the same parts as in the embodiment of the present invention are given the same reference numerals.

Reference numeral 15A denotes a fixture for connecting the steel column 11 and the C-shaped steel 13. The C-shaped steel support body 33 has a plurality of C-shaped steel supports 33 and a plurality of fitting parts 32 that loosely fit with the C-shaped steel 13.

In this embodiment, the mounting plate 30 is made of end-hat section steel, and as shown in FIG.
A space 34 is formed between the outer wall 12 and the support body 33, and the support body 33 has a pair of left and right plate-like support parts 36 that can be opened and closed from side to side via a hinge part 35, and each of these support parts 3G.
The opening/closing side ends of 36 are bent inward, respectively.
two T-shaped fitting portions 3 recessed upward from the upper edge of each support portion 36.36.
It consists of 2. 113.37.38 is each support part 36
．． 36 are provided on the hinge portion 35 side and the engaging end portion 31 side, respectively.]l auxiliary support portions.

In the above structure, the mounting plate 30 is first welded to the outer wall 12 of the steel column 11 as shown in FIG. Then, the left and right engaging ends 31.31 of the support 33 are attached to the central part 30 of the mounting plate.
b and the outer wall 12 of the steel frame column, respectively, and the support body 33 is engaged and connected to the plate 30. In this case, it is desirable that the support body 33 is inserted into the attachment body 30 so that it cannot be easily removed from the attachment body 30.

Thus, the fitting portion 32 of the support body 33 is appropriately fitted into the C-shaped steel 13, and the left and right horizontally opposing walls 13c, 13c of the C-shaped steel 13 are placed on the support portion 36 of the support body. If you do this, type C! 413 is horizontally installed on a plurality of fixtures 15Δ welded to the steel column 11 with the opening 13d facing downward.

"Effects of the Present Invention" As is clear from the above description, the present invention has the following effects.

(1) The fixtures (15A, 15A) can be immediately welded to desired locations on the steel columns or the roof body. There is no need to use extra nerves at the welding location as with conventional fixtures.

Therefore, the work of constructing C-shaped steel is significantly improved.

(2) There is no need to form through holes for bolts in the C-shaped steel connecting wall 16d.

(3) The C-shaped steel can be installed on a fixture so that its long groove or opening 13d faces downward.

Therefore, the problem of rainwater and dirt remaining on the C-shaped steel can be solved.

(4) Since the mounting body (16) or the mounting plate (30) and the support bodies (19, 33) are separate bodies, the mounting body (16) or the mounting plate (30) can be attached to the roof body or the outer wall (12) of the steel column. Welding work is easy.

(5) Since the support body (19) is formed with a support head (19a) that comes into contact with the inner wall of the C-shaped steel, or the support body (33) has a loose connection with the C-shaped steel? Since the fitting portion (32) is formed, it is possible to prevent the C-shaped steel from coming off the support.
