The present invention relates to an interlayer flooring material and an interlayer flooring dry construction method using the same. More specifically, the flooring material can be applied to apartments and apartment houses to minimize the noise between floors, and can provide a number of effects such as workability and cost reduction. It is to provide a dry floor construction method using the interlayer flooring material.

In recent years, as floor impact noise (floor noise) has emerged as a social problem in apartments and apartment houses, the Ministry of Construction and Transportation has revised regulations on housing construction standards, etc., and has established minimum performance standards for concrete floor impact sound insulation performance. As the floor structure is provided as a notice, the performance standard of the cushioning material applied to the standard floor structure is set so that only products with a certain quality or higher can be applied to the construction site.

In order to enhance energy efficiency of buildings in response to the era of high oil prices, interlayer insulation is required to be installed on the floor heating area of multi-unit houses in accordance with the 'Rules on the Facility Standards, etc.'

Most recently, there is an urgent need to develop materials that can solve all of these problems, as the collapse of buildings is aggravated by frequent earthquakes.

However, the existing flooring materials and construction methods of the building were completely cured after the multi-stage process and the partial construction, and the next work process was possible.

In addition, there are many cases of complaints about air pollution caused by various dusts due to frequent entry and exit of ready-mixed concrete vehicles at work sites, and high risk of harmful substances and molds in humans, and floor damage and damage to buildings caused by earthquakes and vibrations. , Sound absorption, soundproofing, dustproof, insulation, heat insulation effect is insufficient, and when a defect occurs, it was not possible to partially correct and had a lot of troubles such as very troublesome work.

Accordingly, the present invention is to provide a new layered flooring material and a layered flooring dry method using the same, which can solve the problems of the existing layered flooring materials and the method of construction of the flooring materials using the same.

The present invention particularly provides an interlayer floor material that can provide a number of effects such as workability, cost reduction and at the same time minimized floor noise, such as the construction of apartments and apartments, and provides a dry floor construction method using the same. The present invention has been completed.

1 is a plan view applying the interlayer floor material provided by the present invention and a method of dry floor construction using the same, FIG. 2 is a perspective view of a state in which the interlayer floor material 1 of the present invention is disassembled, and FIG. 3 is a state in which the present invention is constructed. As one sectional drawing, this invention is demonstrated in detail with these drawings.

The interlayer flooring material (1) of the present invention constructs a noise buffer mat (3) which performs interlayer noise and cushioning functions on the slab (2) top bottom surface, and a heating pipe (4) on the top of the noise buffer mat (3). After pipes are fixed, install the pipe for heating (4) piped using stone powder (5).

And the upper part of the stone powder (5) to the construction of the upper mat (6), and finally to the construction of the floor finish material (7).

In the figure, reference numeral 8 denotes a seam finish material, and 9 represents a side finish material.

The noise buffer mat (3), which performs the interlayer noise and cushioning function, is a high temperature and compression molded product obtained by stirring a moisture-curable polyurethane-based one-component adhesive on an EVA chip at a ratio of 15: 1, and the adhesive is 95% of polyurethane resin. , 2% adhesive strengthening catalyst and 3% viscosity enhancing agent (diluent) .The noise buffer mat (3) has excellent workability (120m ² per person), sound insulation (saving 25% energy), and heating piping work. It is simple to fix the clip, very effective in blocking the impact sound of the floor, and using environmentally friendly materials.

And the upper mat 6 is prepared by mixing the powder to 4.5 parts by weight in 1 part by weight of the latex mixture liquid is dried quickly for about 4 hours at a temperature of 60 ~ 80 ℃ in a drying furnace (heat steam),

The latex mixture is an elastic polymer material composed of latex 26%, diluent 73.97%, ammonia 0.01%, chlorine 0.02% to improve impact resistance and provide elasticity.

50% of the mixed solution is mixed with 50% of water.

Powder used is a mixture of 27% Falkland cement, 14.5% high strength mixture for steam curing, 47.9% silica sand (artificial sand), 10.5% pearlite (artificial resin), and 0.1% fiber.

In the composition of the powder, the high strength mixture for curing the steam increases the cement stiffness and physical properties as a admixture, and serves to reduce the amount of water mixture, and No. 3 silica sand increases the stiffness when mixed with the cement.

And pearlite is excellent in cement and adsorptive power, and lowers the specific gravity, thereby reducing the weight will eventually play a part in the manufacture of a lightweight upper mat (6).

As described above, the upper mat 6 of the present invention prepared by mixing, drying, and curing the latex mixed solution and powder was tested as a general finishing mortar, specific gravity, and compressive strength.
