Hereinafter, with reference to the accompanying drawings for the building floor buffer layer structure having a tubular buffer of the present invention will be described in detail.

The basic configuration of the buffer floor structure for the building floor having a tubular buffer of the present invention,

A heat insulating material 100 made of a synthetic resin material formed under the finishing mortar layer 30 or the lightweight foam concrete layer 20;

It is formed on the lower portion of the heat insulating material 100, and formed on the upper surface of the lightweight foam concrete layer 20 or concrete floor layer 10, the inner tube is formed in an empty tube shape, a tubular buffer material having a synthetic resin material (200) It is characterized by consisting of.

In FIG. 4, an example of the buffer layer of the present invention is formed on the lower portion of the finishing mortar layer 30 and the upper portion of the lightweight foamed concrete layer 20.

In addition, although not shown, the buffer layer of the present invention may be formed on the lower portion of the lightweight foam concrete layer 20 and the upper portion of the concrete floor layer 10.

Insulating material 100 in the present invention is a foam foamed from 1 to 8 selected from polystyrene, polyethylene, polypropylene, polyurethane, polyvinyl chloride, ethylene vinyl acetate, natural rubber, synthetic rubber as a raw material,

Consists of mixed moldings formed by mixing 1 to 8 kinds of foamed crushed products of polystyrene, polyethylene, polypropylene, polyurethane, polyvinyl chloride, ethylene vinyl acetate, natural rubber, and synthetic rubber, or composed of a web fiber layer. .

The heat insulating material 100 may be formed of a member capable of providing a cushioning performance in addition to providing heat insulating performance.

In FIG. 4, the tubular shock absorber 200 installed at the lower portion of the insulation 100 has a hollow tube shape, for example, a straw-like shape, and is made of polyethylene, polypropylene, FBC, FT, ABS, engineering resin. It is characterized by using 1 to 6 selected among the raw materials.

In this case, a suitable amount of 1 to 6 selected from magnetic ceramic powder, piezoceramic powder, carbon powder, graphite, hard coal, and inorganic powder may be mixed with the material.

In addition, the tubular buffer 200 may be coated with any one selected from the aluminum thin film or the aluminum powder mixed pate on the inside or outside to block the infrared rays flowing into the tube from the bottom slab and improve durability.

The tubular buffer 200 may be attached to the heat insulating material 100 using an adhesive or using a double-sided tape.

A configuration example of such a tubular buffer 200 is shown in Figure 4, but is not limited thereto, and may have a variety of structures as shown in Figures 8 to 14.

First, referring to FIG. 8, two or more dogs may be arranged to form a layer in a straight line.

In addition, as shown in Figure 9 to form a plurality of layers up and down may be installed so that the top, bottom cross each other.

In addition, as shown in FIG. 10, each group is formed, but one group may be installed by fixing two tubes horizontally and vertically.

In addition, the upper and lower portions may be arranged differently as shown in FIGS. 11 to 14.

The arrangement and configuration of the tubular buffer member 200 is not limited to those shown in FIGS. 8 to 14, and as will be apparent from the illustrated examples, the multilayer buffers may be stacked in a variety of ways, and may be arranged alternately and side by side.

In the above configuration, an example in which the support plate 300 is additionally installed is illustrated in FIG. 5.

The support plate 300 is installed between the heat insulating material 100 and the tubular buffer 200 in order to prevent damage to the heat insulating material 100 by the upper local load, plastic plate, plastic film, paper, plywood, inorganic powder compression board It can be composed of any one selected from wood flour and plastic composites.

In addition, in the present invention, as shown in FIG. 6, the surface protection material 400 may be additionally installed on the top of the heat insulating material 100.

The surface protection material 400 may be made of any one selected from polyethylene foam, polypropylene foam, FBC foam, nonwoven fabric, plastic sheet, film, film coated paper.

In the configuration as described above, the tubular buffer member 200 may be configured such that the through-hole 210 having a diameter of 1 to 80% of the diameter of the tubular buffer member 200 is formed as shown in FIG.

The reason for forming the through hole 210 is to reduce resonance generated in the tubular buffer 200.

At this time, the shape of the through-hole 210 may be formed in various forms, and when a plurality of tubular buffers 200 form a group, some of the tubular buffers 200 may be formed for the entire group. May be applied to

On the other hand, the tubular shock absorber 200 may be configured such that the incision hole 220 of 1 to 90% of the diameter of the tubular buffer 200 is formed from the bottom side.

The reason for forming the cut-out hole 220 is to reduce the phenomenon and the portion of the cushioning material is lifted from the bottom even when the bottom surface is uneven or there are protrusions or residues.

Such a cutting hole 220 may also be formed for the entire group when a plurality of tubular buffers 200 form a group or may be applied to some of the tubular buffers 200.

In the above configuration, all inorganic materials such as cement mortar, ceramics, and metal oxides radiate infrared rays at temperatures above 0 ° K, which is absolute temperature, and the radiated infrared energy is proportional to the fourth power of the temperature.

Therefore, at room temperature of about 20 ℃ (293 ° K) a very large amount of infrared radiation from the concrete floor layer (10).

At this time, the wavelength of the infrared radiation is generally 2 ㎛ or more, as shown in Figure 17, when the wavelength band of 2 ~ 20 ㎛ range is absorbed by the organic material (PE, PP, Urethane, EVA, etc.) will have a thermal action on the organic material It turns out that it acts to harden an organic substance.

That is, when the organic material is foamed to have elasticity, thermal curing occurs and adverse effects of increasing the elastic modulus appear.

In consideration of this point, an infrared ray blocking layer made of rubber, a resin film, or a sheet material may be formed on the bottom surface of the entire buffer layer to prevent infrared rays from flowing from the outside.

At this time, by coating a metal thin film on one side or both sides of the infrared blocking layer can further maximize the infrared blocking effect.

As described above, the infrared blocking layer prevents infrared rays from entering the foamed organic material, thereby preventing thermal curing, thereby ensuring a long life of the buffer layer.

Experimental Example: Dynamic Elastic Modulus Experiment

In order to confirm the performance of the buffer layer structure of the present invention configured as described above, two types of samples were prepared and the performance was measured.

First, prepare 200 mm thick, 10 mm thick, polyethylene insulation for comparison, and then install 200 mm thick, 200 mm thick, 10 mm thick, polypropylene foam, and flat cushioning material under the insulation. A load was applied to 90 kg / m 2 and the dynamic modulus was measured.

In addition, after preparing a heat insulating material of 200 mm in width, 10 mm in thickness, and polyethylene material as a test object, a 10 mm diameter was placed in the lower part of the heat insulating material. After installing a plurality of furnaces, a dynamic elastic modulus was measured by applying 90 kg / m 2 of applied upper load.

The elastic modulus of elasticity of the comparative object and the experimental object is shown in Table 1 as follows.

<Table 1> Measurement results of dynamic elastic modulus.

Dynamic modulus of elasticity (MN / ㎥) Remarks Measures standard comparison target 8.5 5 Flat buffer Test subject 3.7 5 Tubular Shock Absorber

Able to know.

As a result of the above experiment, the improvement of (47)% in terms of reducing the raw material cost and the conditions that the buffer layer should be provided within a limited thickness will be considerably large.
