The prefabricated panel

Regularly arranged and seated on the seating surface (eg floor slab layer or lightweight layer),

Interconnected through specific means,

By constructing the finishing layer by placing finishing mortar on the upper part, it is possible to conveniently construct the floor between buildings.

The interlayer floor structure of a generally known multi-story building

Floor slab layer, which is installed to basically partition the floors,

Sound insulation layer (or insulation layer for insulation) of the close-up structure to attenuate the inter-layer noise on the top of the floor slab layer,

And lightweight concrete layer (lightening layer),

Finishing mortar layer which is poured in order to bury the heating pipe and to configure the floor smoothly,

It is composed of flooring on top.

On the other hand, the heating pipe in the floor structure

It is fixed by seating and fixing the heating pipe on the top of the fixing device consisting of a plurality of support pieces on the top of the lightweight concrete layer,

Alternatively, in order to fix the heating pipe, the ondol layer of the structure in which the pipe receiving groove is formed is manufactured in a prefabricated panel,

Seating the heating solvent pipe in the receiving groove,

By placing a finishing mortar on the top, there is a structure that the finishing layer is formed at the same time as the laying of the heating pipe.

However, the above assembled panel

The receiving groove for accommodating the heating pipe is formed on the entire surface via the edge of the panel.

There is a disadvantage that the treatment of the U-shaped bent portion of the heating pipe is difficult, and as an auxiliary means for overcoming this, the main panel formed a checkerboard-shaped bone,

Each small U-shaped subpanel is formed with a U-shaped receiving groove.

When working, install the piping by interconnecting in the field,

The prefabricated panel for the edge where the U-shaped bend and the straight part are formed

A method of installing a pipe by interconnecting the main panel with only the linear groove is used.

But in all of the above cases,

A main panel in the center of which a straight groove is formed;

Edge panels for U-shaped grooves should be manufactured separately,

There is a disadvantage that the worker must be assembled one by one.

In addition, since the thickness of the ondol layer made of prefabricated panels is not too thick to accommodate the heating pipes, the receiving grooves cannot be molded deep enough to ensure that the pipes can be stably fixed.

There is a disadvantage that it is difficult to be stably fixed by the rigidity of the piping pipe and the pouring pressure of the finishing mortar.

In general, the prefabricated panel is heavy, but the configuration is not considered considering the convenience of the operator.

For example,

In one embodiment for manufacturing a prefabricated panel of lightweight concrete,

After adding a foaming agent etc. to 40-65% of water cement ratio, it raises a bubble,

After putting the mixed raw materials in the molding die or natural curing at room temperature,

Or in order to shorten the curing time and to produce a good quality of the curing, go to a curing chamber equipped with a heating, pressurization, humidification device to cure under good curing conditions to produce a finished molding (prefabricated panel).

Another example is

Mix lightweight cement with water cement 40 ~ 65%,

Natural mixture at room temperature after the mixture is put into the mold;

Or in order to shorten the curing time and to produce a good quality of the curing, go to a curing chamber equipped with a heating, pressurization, humidification device to cure under good curing conditions to produce a finished molding.

The manufactured molding may be formed with a receiving groove for the pipe, or may be manufactured in a flat plate shape.

However, in the present invention, in order to provide a prefabricated panel eliminated the disadvantages appearing in the existing prefabricated panel formed,

As shown in Fig. 1, the heating pipe receiving groove is formed in a straight or cross shape only at the center of the panel except for the edge of the prefabricated panel, so that the U-shaped bent portion of the pipe can be easily processed.

The orientation of the receiving groove formed in the actual construction

It is manufactured so that it can be installed by simply seating a single type of prefabricated panel without discrimination according to the position such as center, edge and corner.

In addition, in order to reduce the inconvenience of workers due to the high weight of the prefabricated panel,

By constructing the handles on the edges or sides of the prefabricated panel,

The convenience of moving the prefabricated panel was pursued.

Hereinafter, the prefabricated panel according to the present invention will be described in detail through the drawings.
