Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting structure for boards that cover the sides and bottom of an H-shaped steel member.

[Conventional technology]

For steel frame structures such as apartments and buildings,
H-shaped steel beam members are used for the structure,
If this is exposed to the room space, it is necessary to cover the entire area with a fireproof board.

Conventionally, when covering an H-shaped steel member 2 as a beam protruding downward from a ceiling slab 1, as shown in FIG. The base plate 4 for the joint part is pasted on the outer edge of this sillboard 3, and the surface, upper and lower horizontal plates 2 of the base plate 4 for the joint part are pasted.
A fireproof horizontal board 5 was attached to the side edges of b and 2c, and a fireproof lower board 6 was further attached to the lower surface of the lower horizontal plate.

[Problem that the invention attempts to solve]

However, with the above configuration, it takes a lot of effort to cut the adhesive board to match the dimensions of the H-shaped steel, and the board often falls off during work because it is difficult to cut the adhesive board accurately.

Another drawback is that the next work cannot be carried out until the adhesive has hardened, making it impossible to carry out the work quickly. Furthermore, there was a risk that the board would peel off due to deterioration of the adhesive over time or the occurrence of cracks.

[Means for solving problems]

It consists of approximately U-shaped corner clips 10, 10 and a board mounting frame material 14, and the corner clip 1
Attach the bolts 11 that protrude upwards to 0 and 10,
The lower end of the board mounting frame 14 extending upward is attached to this, and the corner clips 10, 10 and the board mounting frame 14 are provided with locking tongues 10e, 14e protruding outward, and a field edge member 16, 17 to attach the horizontal boards 5, 5, and insert the edge members 18, 19 into the locking tongues 10f, 10f provided in each corner clip 10, 10 so as to project downward, and then attach the lower board 6. Install.

[Effect]

The tongue pieces 10e and 14 that lock the field edge members 16 to 19
After fitting by pressing in the directions e and 10f, the horizontal boards 5, 5 and the lower board 6 can be attached by screwing or the like.

9 is to be locked.

The corner clip 10 has an upper surface 10 having a screw hole 10g into which a bolt 11 is screwed, as shown in FIG.
The locking tongue piece 10 consists of U-shaped pieces 10h, 10h bent downward from both edges of d and facing each other.
Two e are provided above and below on the side edges of the vertical pieces 10 ₁ , 10 ₁ constituting the vertical frame 10a in each of the U-shaped pieces 10h, 10h, and both of the above-mentioned locking tongue pieces 10e, 10e are provided. is fitted into the wide field edge member 17. In this case, inwardly curved locking pieces 17a, 17a are provided at both ends of the edge member 17, and these locking pieces 17a, 17a lock in the recesses 10m on both edges of the locking tongue pieces 10e, 10e. In addition, the upper surface 10d
The upper horizontal pieces 10 ₂ and 10 ₂ constitute a horizontal frame 10b, and the lower horizontal pieces 10 ₃ and 10 ₃ have sawtooth portions 10j.
constitute the lower horizontal frame 10c, and the lower horizontal pieces 10 ₃ , 1
From the outside of the lower edge of 0 ₃ , the above locking tongue pieces 10f, 10f
protrudes so as to fit inside the field edge member 19.

Inwardly curved locking pieces 19a are provided at both ends of the field edge member 19.
is provided.

The mounting piece 14a is a piece that protrudes inward from the lower end of the mounting frame 14, and has a groove 14b into which the bolt 11 fits. It is tightened to 11.

The board mounting frame 14 has a U-shaped cross section, is positioned facing outward, and has rising pieces 14m, 14
The locking tongue piece 14e is provided at the tip of m. In this case, the uppermost locking tongue piece 14e is attached to the field edge member 16.
