Description

Sound insulation and vibration suppression structure of apartment floor {STRUCTURE FOR ISOLATING IMPACT SOUND AND VIBRATION OF APARTMENT FLOOR}

The present invention relates to an apartment floor structure, and more particularly, to prevent the impact sound and vibration generated by the impact applied to the floor of the apartment to the lower floor through the concrete slab as well as to the lower floor and the next generation through the retaining wall It provides a comfortable living environment of the apartment by preventing the transmission, and the sound insulation and vibration suppression structure of the floor of the apartment is also simple according to the construction of the sound insulation and vibration suppression structure.

Impact sounds and vibrations generated by impacts such as walking of people and falling of objects on the upper floors of apartments such as apartments are radiated into the lower floors through floor slabs and retaining walls. Such impact sounds and vibrations are incredibly unpleasant for residents of lower generations, so it is desirable to block them as much as possible.

In general, concrete slab is a good sound insulation material because it blocks air propagation well, but when it is directly applied to shock or vibration, concrete slab is converted into solid wave sound and is hardly attenuated. It has a radiating property.

Conventional apartment floor structure is a slab (1) formed by pouring concrete, curing, as shown in Figure 1, a stirrer foam (2) disposed on top of the slab (1), on the stirrer foam (2) Cement mortar (5), and the cement mortar (5), which is applied after the installation of a heating pipe (4) on the lightweight foam concrete (3) mixed with foam granules and mortar as a coating ) Is composed of a surface finish material (6) provided on.

The concrete slab 1 has a thickness of 135 or 150 mm, the styro foam 2 is 20 mm, the lightweight foam concrete 3 is 50 mm, and the cement mortar 5 is 32 mm, respectively.

A 0.03 mm thick P.E film is attached to the upper surface of the foam 2, and monolith or ondol floor is used as the material of the surface finish material 6.

In addition, the retaining wall 7 constituting the side wall of the apartment is formed by pouring and curing concrete together with the slab 1, the wall surface of the retaining wall 7 is provided with a foam (8) of 10 mm thick, retaining wall (7) ) Also has a base 9 attached to the bottom after the paper is papered.

When the lightweight foam concrete 3 and the cement mortar 5 are stretched in the transverse direction according to the temperature change, the stirrer foam 8 absorbs the transverse length change and at the same time the bottom impact sound and vibration retain the retaining wall 7. Through the function of blocking the transmission to the lower floor and the next generation.

The conventional apartment floor structure as described above has a problem that the sound insulation and vibration damping effect is not good enough to provide a pleasant environment for the generation of the lower layer, because only by the foam form (2) (8).

The surface finishing material 6 and the part of the cement mortar 5 are in contact with the retaining wall 7, and the stirrer foam 8 of the retaining wall 7 does not have good sound insulation and vibration damping performance. There is a problem that is delivered to the retaining wall (7) through the finishing material (6) and cement mortar (5) and lightweight foam concrete (3) is radiated to the lower floor generation and the next generation.

In addition, the base plate (9) is directly attached to the retaining wall (7), so when the impact is applied to the base plate (9) by a cleaning tool, such as the impact sound and vibration is directly transmitted to the lower floor generation and the next generation through the retaining wall (7) There is also a problem.

As such, the conventional apartment floor structure does not effectively block the transmission of the impact sound and vibration generated in one generation to the lower floor generation and the next generation, thereby causing inconvenience to residents.

The present invention was devised to solve the above problems of the prior art, by installing a composite vibration damping sheet of the synthetic resin system and the non-woven fabric of the synthetic fiber system between the surface finish material and cement mortar, the impact sound through the slab and To prevent vibrations, and to attach to the retaining wall up to a certain height above the surface finish where the baseboard is installed from the foam on the slab, the composite vibration damping sheet is applied to the lower layer generation and the next generation through the retaining wall. To effectively block the thing to provide a comfortable living environment, and also to provide a soundproofing and vibration suppression structure of the floor of the apartment to simplify the construction due to the configuration of the composite vibration damping sheet of the retaining wall.

The sound insulation and vibration suppression structure of the floor of the apartment of the present invention for achieving the above object is a slab formed by placing and curing concrete, a styro foam disposed on the top of the slab, as a coating on the styro foam In the apartment floor structure comprising a lightweight foamed concrete mixed with mortar, a cement mortar applied after installing a heating pipe on the lightweight foamed concrete, and a surface finish material installed on the cement mortar, a synthetic resin between the surface finish and cement mortar Install a composite vibration damping sheet integrating the vibration damping sheet of the system and the nonwoven fabric of the synthetic fiber system, and attach the composite vibration damping sheet to the retaining wall up to a certain height on the surface finishing material on which the baseboard is installed from the foam on the slab. The composite vibration damping sheet is inserted into the composite vibration damping sheet of the retaining wall protruding onto the surface finishing material. Characterized in that attaching the rail receiving.
