Description

Structure of fireproofing between floors in curtain wall and construct method

The present invention by cutting and pasting or coating the expansion material on one side of the filler material in contact with the curtain wall insulation, filling the space caused by the melting or burning of the insulation by the fire due to the expansion characteristics of the expansion material to move the flame and toxic gas and It can prevent the diffusion, and it is not necessary to install the steel plate on the panel and the building floor, so the construction can be shortened, and the air can be shortened, and the elastic filling material is compressed and filled in the space between the building floor and the outer wall of the building. By absorbing, it can absorb the seismic and wind pressure between the building floor and the exterior wall, and glue or paint the adhesive or coating to the building floor and the filling material and insulation material to fix the filling material so that it cannot escape. Expanding material is provided by filling the space between the outer walls of the building with elasticity and giving it an expansion property. It is a technology of the structure of the construction of the curtain wall interlayer fireproof material that can prevent the movement and diffusion of flame and toxic gas by filling the space created by melting or burning of the heat insulation material by fire due to the expansion characteristic of the material.

Building regulations (eg, Article 40 of the Act, Article 2 of the Building Act, Decree No. 2008-154, Recognition and Management Standards of Refractory Structures, etc.) specify performance standards for certain refractory structures according to the purpose of the building. For wall surfaces, floor surfaces, and the like, a structure that can withstand flame (1,016 ° C or more) for a predetermined time is required.

In order to prevent the spread of smoke and flames into adjacent rooms in case of fire in actual buildings, it is important to seal the penetration in the construction work. In this regard, construction is performed to seal the penetrating part according to the performance of the fireproof structure, which is called fireproof filling construction, and maintains the 'accreditation system' to test, prove and manage the fireproof structure. In order to be recognized as a legal fire-resistant structure, the penetrating part must pass the heat resistance test, and it is given a fire resistance performance grade through a predetermined heat resistance test by an accreditation body.

Insulation materials such as MINERAL WOOL, GLASS WOOL, CERAK WOOL and polyester SKY VIVA, which are generally used as insulation materials in construction work, are widely known products. It is widely used as an intermediate material in the refractory filling structure. However, these insulating materials themselves are excellent in flame retardancy, heat insulation, light weight, price, etc., depending on the product, on the other hand, deterioration, absorption, wear resistance is large, there is a fear of dust generation. In addition, since the high density of fire insulation material is non-stretch, it has been known that there is a problem in using it alone as a filler for fire compartment treatment. In addition, since the thermal insulation material itself is heat resistant in terms of rock wool (MINERAL WOOL) is about 700 ℃, glass wool (GLASS WOOL) begins to deteriorate at about 500 ℃, it is not suitable for a refractory charge structure that must withstand more than 1,016 ℃, conventionally Insulating materials have been used only as intermediate materials.

Figure 1 (a) is a cross-sectional view showing a general construction form of the bottom surface opening through which the penetration material 12 passes in the conventional refractory filling work. The iron plate 20 is fastened to the lower surface of the concrete slab 10 by a tableting nail 21 or the like, and the insulating material 30 such as rock wool is inserted into the penetrating portion 11 of the concrete slab 10 as an intermediate material. Has a structure for filling a separate fire protection material 40 such as a fire protection foam and a fire sealant. 1 (b) is a cross-sectional view of a partition wall connecting portion, which is another form of a conventional fireproof structure, in which a backup material 30 is inserted into the space 51, which is a connecting section of the partition wall 50, inside and It is a structure which fills another fire prevention material 40, such as a fire prevention sealant.

In the conventional construction method, since the worker directly processed the thermal insulation material in the field, the worker was exposed to rock wool dust, and thus there was a problem of excessive industrial waste such as rock wool waste. In addition, in the past, not only the fireproof material is expensive, but also the construction is difficult and the number of work processes are excessive, so the overall construction cost is excessively input, and in practice, the construction site has led to the phenomenon of refractory filling work itself. In addition, the existing field construction method of repeating the application and drying of the fire protection material on the heat-absorbing insulating material has a problem in that it is impossible to work during winter or rainy days.

Therefore, due to the expansion characteristics of the expansion material, it can fill the space caused by the melting or burning of the insulation by the fire, thereby preventing the movement and diffusion of flames and toxic gases. It can shorten the air, compress and fill the elastic material into the space between the building floor and the outer wall of the building to absorb the earthquake and wind pressure between the building floor and the outer wall, and use adhesives or coatings on the building floor. It can be fixed to prevent the filling material from detaching by adhering or painting to the filling material and insulation material. Due to the expansion characteristics of the material, it fills the space created by melting or burning of insulation by fire, The development of the curtain that is able to stop the movement and diffusion of gas May interlayer room fire structure and construction methods that situation is urgently required.
