Description

Floor structure for building and its manufacturing method {Floor for a structure and method for making the same}

The present invention by spraying and applying the pulverized particles of the synthetic resin waste material with a flame retardant and a binder to construct them directly in the field as a floor flame-retardant sound insulation layer of the building, to improve the insulation, sound insulation and non-combustible properties and improve construction workability The present invention relates to a floor structure for a building and a method of manufacturing the same.

In general, in buildings such as buildings, apartments, and factories, efforts have been made to create a comfortable and comfortable environment free from all the inconveniences caused by ambient noise or climatic factors.

In particular, in the case of apartment-type residential facilities such as apartments, the condition for blocking external noise and heat is desperately required. For this purpose, in the case of the construction of a conventional building, sound insulation (dustproof) is essential to block shock or noise and improve insulation characteristics. Flooring is carried out using ash.

As a soundproof dustproof material, a lot of measures have been introduced to solve environmental problems and to obtain economic benefits by using waste materials.

For example, Korean Patent No. 147842 discloses a floor soundproofing material comprising a synthetic resin waste material rubber powder, a urethane-based binder or a binder in which a vinyl acetate emulsion and a vinyl acetate-ethylene emulsion copolymer are mixed.

In addition, Korean Laid-Open Patent Publication No. 2001-1109 (January 5, 2001) discloses a granular synthetic resin waste material rubber powder having a surface portion composed of a mixture of fine synthetic resin waste material rubber powder and a binder and a particle size of 1-5 mm or more. The present invention discloses a high temperature compression molded rubber pad for soundproof insulation insulation produced by high temperature compression molding of a mixture of a binder and a binder.

As another example, Korean Utility Model Publication No. 20-201314 (August 19, 2000) includes a soundproof (dustproof) layer formed by pulverizing synthetic resin waste materials and waste rubber, and mixing and curing a binder or a binder made of polymer, Disclosed is a soundproof (dustproof) insulation interior material for a floor of an apartment house comprising a sheet made of expanded polyethylene attached to an upper surface thereof, and a film formed of an uneven portion formed on the upper surface thereof.

It is true that the above-described conventional floor structures are employed in apartment houses to realize some degree of dustproofing and soundproofing effects.

However, conventionally known floor soundproofing dustproof material and rubber pads have a problem in that a gap is generated because the floor is pre-formed in the form of a plate, and as a result, insulation and sound insulation are reduced.

In addition, the conventionally known soundproof (dustproof) insulation interior material is laminated with a soundproof (dustproof) layer and sheets and films, which is complicated in structure and many manufacturing processes, and the structure of the soundproof (dustproof) layer is simple and functional. This weakness is a problem that the insulation and sound insulation effect is somewhat lower.

In addition, conventionally known soundproofing (dustproof) insulation interior material is easily burned, there is a problem vulnerable to fire.

In order to solve the problems of the prior art, an object of the present invention is to insulate by spraying the pulverized particles of synthetic resin waste material with a flame retardant and a binder by directly constructing a flame-retardant sound insulation layer of the whole bottom surface in the field, To improve the sound insulation and non-combustible properties, and to improve the workability in the field construction, and to provide a building floor structure and its manufacturing method.

In accordance with the above object, in the present invention, a foundation concrete layer is installed on the bottom surface of the building, and the upper surface of the concrete layer is obtained by spraying and applying on site, including linear particles, flame retardant, and binder of synthetic resin waste material, and curing them. The present invention proposes a building floor structure which is formed by integrally forming a flame retardant sound insulation layer without a single layer, and laminating a bubble concrete layer and a mortar finishing layer on the flame retardant sound insulation layer.

In addition, the present invention is a construction method for realizing the above-described floor structure, the step of constructing the foundation of the building with steel frame and reinforcing structure and pouring the foundation concrete layer thereon; Spraying and applying the linear particles, flame retardant, and binder of the synthetic resin waste material together using a foam spray nozzle on the upper surface of the foundation concrete layer, and curing them to construct a seamless integral flame retardant sound insulation layer; Constructing a foamed concrete layer on an upper surface of the flame retardant sound insulation layer; And it proposes a method for manufacturing a building floor structure comprising the step of laying a mortar finishing layer on the top surface of the foam concrete layer.

Preferably, ethylene vinyl acetate (E.V.A) may be used as the synthetic resin waste material.

EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described based on an accompanying drawing.
