Description

[Detailed Description of the Invention] This invention relates to a clip for attaching a base lath to a wall formed by spraying a fireproof wall material such as rock wool mortar.

Conventionally, in the construction of fireproof walls, studs were built with a predetermined distance left and right between the floor slab and the ceiling slab, and then metal lath was layered on both sides of the studs, and the metal lath was attached to the studs using clips. Fix it.

Thus, walls were formed by spraying fireproof wall materials such as rock wool mortar onto the metal lath from outdoors and onto the metal lath from indoors to a predetermined thickness.

However, if the wall material cannot be sprayed from outside due to adjacent buildings, etc., the wall material may be sprayed from indoors onto the outdoor metal lath, then the indoor metal lath is fixed, and then the indoor metal lath is sprayed. Since the wall material was spray-painted, the space between the outdoor wall and the indoor wall became narrow, and there was a drawback that it was not possible to obtain the space specified for a fire-resistant structure.

This has resulted in the disadvantage that wide studs must be used to obtain the set space.

Therefore, there is a method in which the metal lath is protruded toward the outdoors through a protruding clip on the stud to solve the above-mentioned drawbacks.

This protruding clip fits the planar U-shaped fitting part extending from the end edge of the metal board into the side plate of the stud, and bends the locking piece extending from the end of the board to the side plate of the stud. The above-mentioned locking piece is circumscribed on the surface to prevent the fitting part from falling off the side wall of the stud.Then, a metal lath is inserted into the protrusion protruding from the front edge of the board, and the metal lath is bent by bending the protrusion. I am trying to install it.

This known protruding clip is formed from a single metal plate, so if a fire breaks out in an adjacent building, high heat will be transferred from the metal lath of the exterior wall, through the protruding clip, to the studs, and then to the metal lath of the interior wall. However, there was a drawback that the fire spread due to the transmission of high-temperature heat.

This idea aims to eliminate the above-mentioned drawbacks by preventing high-temperature heat from being transferred from the metal lath of the outer wall to the studs.

This idea includes a fitting part that fits into the side wall of the stud at the end of the insulation board, and a locking piece that circumscribes the surface of the main wall of the stud by bending, and a bendable part that sticks into the metal lath at the tip of the insulation board. To provide a lath attachment clip which is provided with a protruding piece and prevents high-temperature heat from being transmitted by a heat insulating plate.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, 1 is a heat insulating board made of asbestos or the like, and a metal plate 2 fixed to the end of the insulating board 1 is provided with a U-shaped fitting part 3 that fits into the side wall of the stud. .

In the illustrated case, the fitting part 3 includes a front plate 4 which is connected to the plate-shaped body 2 and projects laterally from a side edge portion toward the distal end surface of the heat insulating plate 1, and a bent part 5 from the front plate 4.
A rear plate 6 is folded back to be parallel to the front plate 4 at a predetermined interval.

Further, the plate-like body 2 is provided with a locking piece 7 that projects from at least one of the upper and lower edges of the end surface of the heat insulating plate 1.

In the case shown in the figure, the above-mentioned locking pieces 7 are made to protrude vertically in two pieces, and after fitting the fitting part 3 to the side wall of the stud, the locking pieces 7 are bent so as to fall backward, and then attached to the main wall surface of the stud. The side edges of the locking piece 7 are circumscribed.

Reference numeral 8 denotes a metal plate-like body fixed to the tip of the heat insulating plate 1, and protrusions 9 are provided at predetermined positions on the periphery of this plate-like body 8.

In the illustrated case, the above protruding pieces 9 are made to protrude forward so that the upper and lower pieces form a set, and are bent after being pierced by the metal lath.

The method of fixing the plate-like bodies 2 and 8 to the heat insulating plate 1 is as follows:
In the illustrated case, the plate-like body 2 is bent into a cylindrical shape and fitted into the end of the heat-insulating plate 1, and the plate-like body 8 is bent into a U-shape and fitted into the tip of the heat-insulating plate 1, and then the plate-like body 2 , 8 by pressing a V-shaped notch 10, and the inner tongue piece 11 of this notch 10 was pressed into the heat insulating plate 1. good.

The clip A according to this invention has the above-mentioned structure. Next, the method for attaching the metal lath will be explained. After fitting the fitting part 3 into the outdoor side wall 12 of the built stud B, main wall 1
The end of the clip A is locked to the stud B by bending the locking piece 7 so as to circumscribe the surface of the clip A.

After that, the metal lath C is stuck into the protruding piece 9, and then the protruding piece 9 is bent to support the metal lath C at the tip of the clip A.

Note that a wall having a predetermined thickness is formed on the metal lath C by spraying a fireproof wall material such as rock wool mortar.

As described above, according to the metal lath attachment clip according to this invention, a fitting part and a locking piece are provided at the end of the insulation board made of asbestos, etc., and a projecting piece is provided at the tip of the insulation board. The high-temperature heat transmitted from the metal lath to the studs due to a fire is blocked by the insulation board.

Therefore, the spread of fire to the inner wall can be prevented.
