The present invention relates to a new method to solve the problem of insulation between the floor noise and the floor that is a problem in the apartment. According to the legislation on the floor, which was instructed by the Ministry of Construction and Transportation in 2006, apartment houses must be constructed with a wall slab thickness of 180 mm or more for wall structures. In this case, it is inevitable to increase the construction cost and reduce the number of households in apartments subject to some diagonal restrictions.The Ministry of Construction and Transportation prepared a draft that set the performance rating of the floor impact sound, including five standard floor structures, in order to reduce the noise between floors of apartment buildings. According to this test, five floor structures that satisfy the minimum standard of 58dB, the lightest impact sound, are selected among the floor impact sound of MDU. Accordingly, the thickness of floor slab should be increased from 135mm to 180mm for wall-type apartments to alleviate light and heavy impact sounds. In the case of ramen groups such as steel frames, 15mm is strengthened from 120mm to 135mm. In addition, a buffer material having a thickness of 20 to 40 mm and a heat insulating material having a thickness of 20 mm or more that satisfy the density, the amount of absorption, and the like must be included. Thus, according to the guidelines of the Ministry of Construction and Transportation, it can be seen that the standards on the floor become very strict against the noise and insulation, among the heavy impact sound.

However, this problem corresponds to the case of installing the floor heating by conventional wet. The Ministry of Construction and Transportation, however, says housing construction companies can use their own floor structures that have been approved by the Institute of Construction Technology, Housing Corporation, etc., as long as they meet the noise level.

Therefore, according to the guidelines of the Ministry of Construction and Transportation when building the floor in the conventional wet, construction costs are bound to increase.

The wet construction increases the weight from 150 kg per square meter to 200 kg, an increase of more than 33%. When this is calculated as a lamination load, a considerable amount of reinforcement enters, resulting in an increase in construction costs. In fact, if this notification is enforced, the construction cost per household will increase by 1.7 million won from 34 pyeong (25 pyeong). In particular, when the floor slab is thicker, the 20-story apartment is about 1 meter high.

Here you can list the problems of wet construction.

1. It is difficult to make the floor horizontal.

2. It takes a long time to install.

3. The hazardous environmental substance cement poison comes out.

4. It takes a lot of heat to heat the floor.

5. The slab thickness should be thicker, and additional costs will be incurred for insulation and noise prevention.

6. If plumbing leaks, remove the entire floor and rebuild.

7. The cost is very high when installed according to the Ministry of Construction and Transportation.

In addition, the Ministry of Construction and Transportation and the Ministry of Commerce, Industry and Energy have introduced the “Energy Efficiency Rating Labeling System” for apartments and other buildings, inducing the efficient use of energy by attaching up to five star-shaped labels for each grade. The choice of material is a very important issue.

Recently, floors with floating floor structures with relatively low noise and vibration have been spotlighted in accordance with the interlayer noise regulation of the bridge.

The present invention was developed to solve the problem of heating the floor by the wet construction as described above, the support for forming a floor structure on the slab, or the support for using the extrusion support and air spring in place of the support for the support and float The present invention relates to a construction method using flooring insulation and plate-like materials with built-in structural materials.

When described with reference to the accompanying drawings developed by the present inventors to solve the technical problems as follows.

Figure 1 is an exploded perspective view showing the state of placing a crutch on the air spring crutch pedestal which is an important element of the present invention.

Herein, the air spring crutch 20 is the inventor of the patent application 10-2006-0026366 (the crutch using the air spring), patent application 10-2006-0026558 (the crutch using the air spring formed air injection unit) Can I see you? Briefly described as follows.

 Air spring support (20) is a principle that supports the floating floor structure of a building under considerable load with levitation to prevent heavy shocks, vibrations, shocks, etc. from the top using a cylinder, air spring and compressed air. There is a purpose.

Place a waterproof crutch on the air spring crutch 20 or use a plastic extrusion that does not rot as a crutch instead. At this time, the plastic extrusion molding, but the present inventors filed in the patent application 10-2006-0025931 (extrusion molding support instead of the support), briefly described as follows.

It has a rectangular cross section and replaces the crutch with a plastic extrusion molding having a plurality of through holes inside the cross section, and has high oil resistance, chemical resistance, and structural strength.

The support spring on which the crutch is seated is fixed to the slab 40 using a tackle using an air compressor, but the waterproof film 50 is placed directly on the slab 40 so that moisture of the slab 40 does not rise. It is preferable to attach.

Figure 2 is an exploded perspective view showing a state in which the composite plate-like material is stacked on the crutch in the construction method of the present invention,

Leveling by adjusting the height adjuster of the air spring support brace 20, it is preferable to use equipment such as a laser pointer. Thus, the composite plate-like material 30 is installed on the air spring support brace 20 is formed horizontally has excellent thermal insulation and high noise blocking effect.

In this case, the composite plate material 30 may refer to Patent Application No. 10-2006-0027280 filed by the present inventors (plate material having a built-in insulation and structural material for floating floor structure), but briefly described as follows.

The outer frame is formed between the rectangular upper plywood and the lower plywood, and is a plate material filled with honeycomb, urethane, honeycomb and urethane inside the outer frame, and the outer surface of the plate material is urethane coating, PET thin film plywood, tepro coating, It is characterized in that a waterproof film is formed by attaching a thin film Teflon sheet.

In particular, the surface of the composite plate 30 is preferably a plywood coated with Teflon, refer to the patent application 10-2006-0027243 (teflon coated plywood) filed by the present inventor, but briefly described on the plywood It is characterized by waterproof, non-adhesive, oil-free, heat resistance, insulation, chemical resistance and low coefficient of friction.

3 is a side view showing that the floor structure is formed by the construction method of the present invention on the slab,

Install the waterproof film 50 on the slab 40, mount the air spring brace 20 on the waterproof film 50, and then install the support 10 on the air spring brace 20, On it, the composite plate-shaped member 30 is raised to make a floating floor structure.

The effects of the present invention configured as described above are as follows. In general, compared with the plywood forming the floating floor structure, the tensile, compressive strength is high, light, strong, and effective for insulation. In particular, it has a significant reduction in interlayer noise and vibration compared to conventional materials. In particular, the composite plate-like material is made of honeycomb and urethane, the noise reduction and heat insulation effect is superior to the conventional wet construction. In particular, it is possible to considerably reduce the energy of the heavy-weight sound generated from the entire floor by raising the floor itself to the air.

The revised Ordinance of the Regulations on Building Equipment Standards, etc., which was implemented from June 1, 2001, lowers the standard of heat transfer rate of building parts by region (Attachment 4 of the notice from the Ministry of Construction and Transportation) and consequently strengthens the insulation standard of buildings by more than 20%. As a result, the use of high thermal conductivity insulation material causes the wall thickness to become relatively thick.As a result of the new amendment and the Ministry of Construction and Transportation, the rigid foamed polyurethane foam is designated as the lowest thermal conductivity of the “A” grade in the regulations. In addition, when the thickness is determined in consideration of heat transfer resistance, since it is about half the thickness of the foamed styrene foam, it can be advantageous to secure indoor and outdoor spaces and the cross section of the building.

In addition, the air spring support 20 is much safer than conventional wall buildings against vibrations such as earthquakes.

Thus, heating or flooring may be installed on the floor formed of the floating floor structure as needed.
