Description

[Detailed description of the invention] This invention relates to a pedestal for a building embedding tool used when installing a heat insulating board on a horizontal slab or a sloped roof on the top floor of a reinforced concrete or steel-framed reinforced concrete structure.

Conventionally, when attaching an embedding tool to a heat insulating board laid on a slab formwork, use a drilling tool to make a hole at a predetermined position in the insulating board, place the embedding tool inside the hole, and then attach it to the slab using a nail. Currently, it is fixed directly onto the formwork.

However, this method is extremely unreasonable in terms of insulation construction, tends to cause condensation, and has serious drawbacks in practical use.

This idea was developed in view of the above-mentioned conventional problems, and its purpose was to precisely place embeddings on formwork on which insulation boards were laid when constructing a horizontal slab or a sloped roof on the top floor. It is an object of the present invention to provide a pedestal for a built-in fixture for a building, which can be mounted in a rational manner, improves workability, and provides practical reliability.

In order to achieve the above object, this invention is a pedestal that supports an embedding tool on the top surface of a heat insulating plate, in which the pedestal is equipped with a female screw body that can rotate in the direction of the elongated hole in a support body that has an elongated opening. A long hole is formed in the center of the bottom, and nail holes are provided on both sides of the hole along the short side thereof, and a hole is formed in the outer circumferential direction surrounding the hole. It is characterized in that a sleeve protruding toward the pedestal is provided integrally with the pedestal.

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

Fig. 1 is a plan view of a pedestal for a built-in device according to an embodiment of this invention, Fig. 2 is a front view of the center longitudinal section of the same, Fig. 3 is a side view of the center longitudinal section of the same, and Fig. 4 is a longitudinal sectional view of the same. It is a bottom view.

The pedestal 1 of the building embedded device shown in the above figure is made of synthetic resin or the like, and has a long hole-shaped through hole 3 formed in the center of a bottom surface 2 having a substantially rhombic shape in plan view. Guide tubes 4, 4 with nail holes 4a, 4a protruding downward on both sides via the short side of the
are arranged opposite to each other, and a sleeve 5 is provided that protrudes downward from the outer periphery surrounding the through hole 3 and the guide tubes 4, 4 with nail holes.

Reference numeral 6 denotes a peripheral edge portion protruding from the upper surface along the periphery of the through hole 3 of the seat surface 2, and is formed to allow the implant A to be mounted thereon.

The embedding device A has a female threaded body b that is rotatable in the direction of the long hole in the support body a whose bottom surface is opened in the shape of a long hole.
was installed by being pivotally supported by a concrete anchor piece C, and mounting nails N, N were provided on the outside.

An example of the use of the pedestal of the built-in device constructed as described above will be described below.

As shown in FIG. 5, a substantially circular mounting hole H is large enough to allow only the guide tubes 4 with nail holes of the pedestal to be inserted into a predetermined position of the heat insulating plate D laid on the slab formwork P in advance. to be drilled.

Then, insert the nails N, N of the embedding device A into the guide tubes 4, 4 with nail holes of the pedestal 1, and insert them into the mounting hole H with the pedestal 1 and the embedding device A combined. , tap the upper part of the embedding tool A with a hammer or the like to completely insert the sleeve 5 of the pedestal 1 into the heat insulating plate D to complete nailing.

After concrete is poured and cured, the slab formwork P is dismantled, and a support bolt (not shown) or the like can be vertically supported on the female threaded body b of the embedding tool A.

Further, by inserting support bolts into the heat insulating plate and rotating them along the elongated holes of the pedestal, it is possible to support the pedestal in an oblique direction as well.

In this way, according to the pedestal of the above embodiment, the center of the mounting hole H and the axis of the female threaded body b of the implant A can be set on the same axis by the guide tubes 4, 4 with nail holes. , construction accuracy can be further improved,
Moreover, it can be expected to have a reinforcing effect on nails.

In addition, since the sleeve 5 and the seat surface 2 completely close the upper surface of the mounting hole H, it is possible to prevent concrete slag from entering the interior, and the seat surface 2 can also prevent it from sinking into the heat insulating plate D. , has excellent reliability and is extremely effective in practice.

In addition, if the guide cylinder with nail holes of the above embodiment is formed to a length suitable for heat insulating plates having various thicknesses, workability and reliability can be further improved.

Next, as another embodiment of this invention, if the thickness of the heat insulating board is quite thick depending on the region, the guide tube with the nail hole is omitted, or the guide tube with the nail hole is made to be about the length of the sleeve,
It is also possible to easily provide nail holes in the seat surface, and the initial effect of preventing the embedded tool from sinking into the heat insulating board can be expected.

In addition, as another example, it is easy from this idea to design a sleeve (arc-shaped part) near the center that protrudes below the seat surface to follow the inner surface of a circular hole H drilled in the heat insulating plate. It is possible to speculate.

As explained in detail above, according to this invention, embeddings can be accurately placed in the slab formwork on which the heat insulating board is laid.
A pedestal for a built-in fixture for a building that can be mounted rationally, can be installed in close contact with the heat insulating board, and can be expected to prevent the embedded fixture and the pedestal from sinking into the heat insulating board, and is extremely effective and reliable in practice. can be obtained.
