Description

[Detailed description of the invention] In recent years, the use of heat insulating materials has increased significantly, and although it has become common knowledge to use them on walls, ceilings, etc., it is not enough to use them under floors. The reason for this is that the space under the floor is narrow and it is difficult to work from below. Therefore, we devised a device that can be easily installed from the floor.

In the figure, 1 is a joist, and in the conventional construction method, a board is nailed down from below and insulation is placed on top of it, so workers have to go under the floor to install it, but with the present invention, they do not. That is, the receiving body 2 made of flat iron material has both ends raised to form a rising part 7,
This is further bent horizontally to form receiving pieces 3, 3, nail holes are provided in them, and receiving pieces 3 are placed on the upper surface of the joist 1 and nailed. A part of the receiver main body 2 is extracted to form a long spigot 4 with a sharp tip, and its end 5 is constructed so that it can be bent. 6 is a cutout hole formed by extraction. The installation of the present invention involves installing the support body 2 between the joists 1 and 1, fixing it on the joist with the support piece 3, and inserting the raised insert 4 into the heat insulating material 14 placed from above. The flat rear end portion 5 of the heat insulating material is bent and fixed. In the case shown in Figures 3, 4, and 5, the receiver body is divided into left and right halves so that it can be used depending on the size of the joist spacing (in the left-right direction in Figure 1).
11, for example, the insertion metal 4 is provided on the receiver main body 8, cutout holes 9 and 10 are provided, and a hooking protrusion 12 bent in a U-shape is created on the other receiver main body 11. By engaging either the cutout hole 9 or 10 as shown in Fig. 3, the receiving pieces 3, 3
The spacing between the joists 1 and 1 is adapted to one of two types. 13 is an example in which a hooking protrusion is provided on the receiver body 8 side.

Since the present invention is as described above, the receiver body 2 is installed from above the joists 1, and the heat insulating material 14 is placed and fixed on top of it, so that workers such as carpenters can do so from above the joists without having to crawl under the floor. Installation of insulation material is easy. However, since the work is simple and quick, it promotes the use of insulation materials under floors, which in turn brings about energy savings.

Further, the insert 4 can be easily and inexpensively made by press working the receiver body 2 without using any other materials.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. A long insert with a pointed tip that has a base on the receiver body by raising both ends of the receiver body made of flat iron material and then bending it horizontally again to form a receiver piece. An underfloor insulation receiving bracket that is provided by extracting the following from the receiving body. 2. In the underfloor insulation receiver described in the preceding paragraph, the receiver body is divided into two parts, left and right, and on the other hand, the long, pointed insert for fixing the insulation material is pulled out from the main body and installed in an upright position. It is made up of a plurality of cutouts into which the engaging protrusions provided on the other receiver body fit and engage.
