Description

[Detailed description of the invention] This invention is for securely supporting the metal insert 1 of a ceiling insert, which is used by fixing it to a formwork before concrete is poured, on a synthetic resin support 2 at a construction site, etc. be.

As a method of supporting the above-mentioned objects, it is possible to use adhesives, etc., but it is difficult to always obtain stable support strength due to differences in the amount of adhesive, etc. applied and the area to be applied, and it also reduces productivity. However, there is a drawback that it cannot be mass-produced at low cost.

As shown in FIG. 2, the present invention provides a recess 3 on the outer periphery of the body of a metal insert 1, and further provides a protrusion 4 inside a synthetic resin support 2, which is press-fitted into the recess of the insert. The convex portion of the support body is completely fitted, and the insert can be reliably supported in a stable state. In this way, support strength can be obtained reliably, and when the synthetic resin support 2 is nailed to the formwork at the construction site, the metal insert 1 will not fall out due to the impact force of the hammer, and the concrete will be poured. Even at times, the insert does not slip out of the support due to the pressing force of the concrete.

Figure 3 shows a diagram of the installation of the ceiling insert at the construction site.

The ceiling insert of the present invention has a metal insert 1 with a recess 3 and a synthetic resin support with a protrusion 4.
The insert is provided internally and press-fitted to reliably support the insert.
By vertically changing the positions of the concave portion of the insert and the convex portion of the support body, it is possible to adjust the depth of embedding in the concrete, which has the advantage of increasing the suspension strength of the ceiling insert.

Figure 4 shows how the ceiling insert is used after adjusting the burial depth.
