Description

[Detailed Description of the Invention] The present invention relates to an insert for an insulated ceiling that is used for suspending predetermined appliances, pipes, etc. from an insulated ceiling whose ceiling surface is covered with a heat insulating material.

Conventionally, there is an insert for heat insulating ceilings as shown in FIG. 4, which uses an insert main body 21 having a female screw portion 21a in the axial direction, and a plurality of nails 22 to attach the heat insulating material 23 and the mold. The base hole 26 provided in the heat insulating material 23 and the insert body insertion hole 25a of the seat body 25 are made approximately concentric, and the seat body 25 is fixed to the frame 24 using a plurality of nails 22. is fixed to both the heat insulating material 23 and the formwork 24, and the insert main body 21 is inserted into the prepared hole 26 of the heat insulating material 23.

Therefore, the seat body 25 is connected to the heat insulating material 23 and the formwork 24.
Since a plurality of nails 22 are used to fix the concrete to the concrete, nailing work is troublesome, and when the formwork 24 is removed after pouring concrete, a large number of nails 22 are used.
The problem is that the nails 22 protrude from the ceiling surface, and post-treatment of the nails 22 is troublesome. In addition, insulation material 2
There are three thicknesses for each size. For this reason, the length of the nail 22 is also required for each size.

In view of the above-mentioned drawbacks, the present invention was developed with the aim of easily and quickly fixing the insert and eliminating the need for any post-processing after removing the formwork.The basic structure of the present invention is as follows: An insert main body is a cylindrical body whose upper end is closed and is provided with a female thread, and an insertion hole for inserting the insert is passed through the insert body, and a seat body fixing screw is inserted at an appropriate distance from the insertion hole. and a seat body protruding in the axial direction of the insertion hole, and the seat body is rotated around a seat body fixing screw and the screw is screwed into the heat insulating material to form a pilot hole in the heat insulating material. The seat body is fixed to the heat insulating material with the seat body and the insertion hole of the seat body substantially concentric with each other, and the insert body is inserted and supported in the lower hole of the heat insulating material by passing the seat body through the insertion hole.

Hereinafter, the present invention will be explained in more detail with reference to Examples.

1 and 2, the heat insulating ceiling insert according to the present invention consists of an insert body A and a seat body B.

The insert body A has a cylindrical shape with a closed upper end, and has a female screw portion 1 between the lower end and the approximately center part.
A collar 2 is provided at the upper end to increase fixing strength.

An insertion hole 3 for inserting the insert A is penetrated near the circumference, and this insertion hole 3
A seat body fixing screw 4 is provided to protrude in the same direction as the axial direction of the insertion hole 3 at an appropriate distance.

In order to embed the insert with the above structure in the surface layer of a heat-insulating ceiling, as shown in Figure 2A, a heat-insulating material D made of wood wool board, foamed plastic board, etc.
A prepared hole 5 having an inner diameter into which the insert main body A can be inserted is provided at a predetermined location in the figure, and as shown in FIG. By screwing into the heat insulating material D, the seat B is fixed to the heat insulating material D by making the lower hole 5 provided in the heat insulating material D and the insertion hole 3 of the seat body B substantially concentric, and then the seat body B is fixed to the heat insulating material D, as shown in FIG. When the insert main body A is inserted through the insertion hole 3 of the seat B and into the lower hole 5 of the heat insulating material D, the insert main body A is supported by the seat B fixed to the heat insulating material D and becomes unable to tilt. Become. In this state, when concrete C is poured and formwork E is removed after concrete C has hardened, the ceiling surface is covered with heat insulating material D, and the concrete poured on the ceiling is Both the insert main body A and the seat body B are buried in the surface layer part of C.

Further, as shown in FIG. 3, a guide tube 6 may be provided on the seat body B' to further stabilize the support of the insert body A. In addition, in Figure 2, 7
indicates a hanging rod with a male thread at its tip.

Since the present invention has the above-described configuration, it has the following effects.

(1) The seat body is fixed to the heat insulating material by rotating the seat body and screwing the seat fixing screws into the heat insulating material. The fixing work can be done quickly and easily, and since it is fixed by screwing, the fixing strength is high.

(2) Unlike the conventional method of fixing the seat using nails, there are no nails protruding from the ceiling surface after the formwork is removed, so post-treatment of the ceiling surface after the formwork is removed is difficult. becomes unnecessary.

(3) With the conventional method of fixing the seat body using nails, the length of the nail used must be changed depending on the thickness of the insulation material, but with this invention, the screws for fixing the seat body are insulated. Since the seat body is fixed to the insulation material by screwing it into the material, it is completely unaffected by the thickness of the insulation material.
