The standard floor structure of the apartment house is formed by laminating the molded concrete slab in the order of sound insulation and insulation, lightweight foam concrete, finishing mortar and floor finishing.

In detail, a sound insulation and insulation material is placed on the concrete slab above the concrete slab, lightweight foamed concrete is placed on the concrete slab 4cm long, a hot water pipe is installed on the top surface, and 4cm of mortar is placed on the floor. As a finishing structure, the height of each member except for the slab is usually about 11.

In this way, most of the apartment houses adopt the standard floor structure, which has the structural problem that the shock noise generated in the upper layer is transmitted to the lower layer.

Therefore, it is necessary to develop a sound insulation material and construction method to solve this problem.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

The accompanying drawings are merely illustrative of and are not intended to limit the scope of the appended drawings in any way.

The overall structure according to a preferred embodiment of the present invention will be schematically described with reference to the accompanying drawings. The sound insulating panel 100, the work tube 200, the horizontal endpoint panel 300, and the vertical endpoint panel 400 are divided into components .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a sectional view of a construction structure according to an embodiment of the present invention.

1, according to the present invention, in place of the conventional construction method in which a concrete slab is molded and then a sound insulation and a heat insulating material are installed thereon, a sound insulating panel 100 having a vacuum formed therein is molded into a concrete slab 400 A sound insulating panel 100 is installed on the bottom surface of the concrete slab 400 by placing a reinforcing bar on the upper surface of the formwork and pouring concrete into the concrete slab 400. A vacuum layer is integrally formed on the bottom surface of the concrete slab 400 to form slab concrete and wall concrete Which intercepts the interlayer noise that is conducted to the lower part.

Such a construction method facilitates the installation of the sound-insulating panel 100 and allows the sound-insulating panel 100 to be closely attached to the wall. Since the vacuum layer is integrally formed on the bottom surface of the concrete slab, It has cost and time saving effect.

Also, since the sound insulating panel 100 is installed on the bottom of the concrete slab, the load applied to the floor is not received by the sound insulating panel 100, so that the sound insulating panel 100 can be lightened and the manufacturing cost can be reduced.

In addition, since the shrinkage, the hardening and the peeling phenomenon do not occur even when the external impact and the temperature change, the sound insulating panel 100 is not deformed even after a lapse of time.

A plurality of air blocks 120 are vertically and horizontally connected to each other to form a vacuum in the interior of the sound insulation panel 100. A lattice protrusion 140 is formed at an upper portion of the air block 120 and a fixing hole 160 is formed at each corner. And is closely installed on the bottom surface of the concrete slab 500 to form a vacuum layer integrally with the lower portion of the concrete slab.

The air block 120 forming the inner surface of the sound insulating panel 100 is a hollow space having an inner space formed by a vacuum and is formed to have a size of about 45 cm by about 30 cm by about 30 cm by about 10 cm, So that the sound insulating panel 100 is formed integrally.

Further, since the lattice protrusions 140 are formed on the upper part of the sound-insulating panel 100 to increase the load strength of the sound-insulating panel 100, the sound-insulating panel 100 is not deformed in the working load during the reinforcing work and the concrete pouring work .

In addition, when the concrete is laid, the lattice protrusion 140 is embedded in the lower portion of the concrete slab 500 to be integrally formed with the concrete slab, so that the sound-insulating panel 100 is not deformed even in the case of external shock and temperature change.

The fixing hole 160 for fixing the sound-insulating panel 100 to the formwork is formed by perforating the corner of the sound-insulating panel 100 and is fixed with a nail.

The work tube 200 installed in the sound insulation panel 100 is a circular tube having an outer diameter of about 12 cm and a height of about 13 cm and passing through the upper and lower portions and has a conduit connecting box 260 and a mounting jaw 240 formed thereon.

The work pipe 200 is installed in the formwork of the sound-insulating panel 100 and then inserted into the sound-insulating panel 100 through the conduit connection box and the drain pipe, (220).

In the structure in which the concrete is directly poured onto the formwork, the conduit connection box is installed on the formwork so that the lower portion of the conduit connection box is opened after the concrete is laid so that the electric wire works at the lower part of the slab. However, And the concrete is poured thereon. Therefore, in order to open the lower portion of the conduit connection box, a work hole 220 penetrating the sound-insulation panel 100 should be formed before concrete is poured.

Also, in order to open the lower part of the drain pipe, it is necessary to form a work hole 220 penetrating the sound-insulating panel 100 before concrete is poured.

The conduit connection box 260 is tightly fixed to the mounting jaw 240 by forming a circular frame 280 corresponding to the mounting jaw 240 formed on the upper portion of the working tube 200 at the lower portion.

The sound insulation panel 100 further includes a horizontal end panel and a vertical end panel for finishing the remaining end portion after installation.

At this time, the horizontal end panel is subdivided into 5 cm, 10 cm, 15 cm, 30 cm, 45 cm, 60 cm, 75 cm, 90 cm, To the end panel.

In addition, the lengthwise end panel is subdivided into a length of about 5 cm, about 10 cm, about 15 cm, about 30 cm, and about 45 cm, and a sound-deadening panel 100 is installed.

This is to standardize the sound insulating panel 100 so as to minimize the number of the sound insulating panels 100 installed in accordance with the installation area and shape and simplify the installation.

Also, the sound insulation panel 100 is made of synthetic resin including polyethylene and polypropylene so as not to be deformed to the working load during the reinforcement work and the concrete pouring work.

In addition, the sound insulating panel 100 can replace the vacuum formed therein with air, thereby reducing the manufacturing cost.
