Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a steel beam or column made of H-shaped steel or the like, which is attached to the steel beam or column by using tapping screws when the fire-resistant coating is performed using the fire-resistant coated plate. The present invention relates to a mounting bracket for fixing.

[0002]

2. Description of the Related Art Conventionally, a U-shaped fitting as shown in FIG. 4 has been generally used as a fitting of this kind. The mounting bracket is fixed to the lower flange portion b of the steel beam a on the upper end plate 1'under the application of welding means, and the fireproof coating plate c is attached on the lower end plate 2'under the application of tapping screws d. It can be fixed.

[0003] The conventional mounting metal fittings require a professional job such as welding for the mounting work to the steel frame beams and columns, and it is not only difficult to secure human resources, but also welding sparks need to be cured, which is troublesome.

The present invention has been made for the purpose of eliminating such conventional problems.

[0005]

According to the present invention, a U-shaped metal fitting body having upper and lower end plates and a web portion connecting between the end plates is parallel to the upper and lower end plates in the same direction. Protruding into the,
An intermediate plate punched out from the web portion is provided, and an insertion interval is formed between the intermediate plate and the upper end plate for the flange portion of the steel beam or column, and the lower end plate has an insertion hole for a set bolt. However, the intermediate plate is provided with through-screw holes to be screwed into the set bolts right above the insertion holes, respectively. .

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the present invention, the metal fitting body A is U-shaped,
It is composed of upper and lower end plates 1 and 2 and a web portion 3 connecting the end plates 1 and 2. The web part 3 is formed with an intermediate plate 4 protruding in the same direction as and parallel to the upper and lower plates 1, 2 between the intermediate plate 4 and the upper plate 1, and the flange part b of the steel beam a. It has an insertion interval of 5 in.

An insertion hole 6 for the set bolt e is formed in the center of the lower end plate 2, and a through-type screw hole 7 screwed with the set bolt e is formed in the intermediate plate 4 just above the insertion hole 6. Is provided. In the illustrated example, in order to obtain the screw hole 7, the nut 8 is fixed on the intermediate plate 4, for example, on the lower surface side. The insertion hole 6 of the set bolt e is preferably large in consideration of workability.

FIG. 3 shows one use situation of the fitting of the present invention. First, an insertion interval 5 between the upper end plate 1 and the intermediate end plate 4 is shown.
At the lower flange portion b of the steel beam a, then the set bolt e is screwed into the screw hole 7 of the intermediate plate 4 through the insertion hole 6 of the lower end plate 2, and the mounting bracket is flanged by tightening the set bolt e. It is firmly attached and fixed to the part b. After mounting and fixing, fireproof coated plate c
Can be attached and fixed to the lower end plate 2 of the mounting bracket by using the tapping screw d.

In the present invention, when the set bolt e is tightened, a part of the bent portion 4a is prevented so that the intermediate plate 4 does not rotate downward with the base end bent portion 4a as the fulcrum of rotation. The recess 9 can be formed by punching downward using a chisel or the like. The state of formation of the recess 9 is shown enlarged in FIG. In the examples, beams have been mentioned, but the same can be used for columns.

[0011]

[Effects of the Invention] According to the mounting bracket of the present invention, since it can be mounted and fixed to the flange portion of the steel beam or column under the application of the set bolt, the welding work as seen in the conventional products is not necessary at all, and welding It has the feature that it can eliminate problems related to work.
