Description

FIELD OF THE INVENTION [0001] The present invention relates to a method for forming a refractory filling structure in a metal pipe which has been thermally insulated for a penetration portion of a building,

The present invention can finish the refractory filling operation without removing the insulating material even when the insulation is completed, thereby making it easy to work and reduce the construction cost, and it is possible to provide a thermo-expansive tape between the heat insulating material and the through- In the case of a wall or a wall, it is inserted into the left and the right so that the refractory performance can be ensured by filling the gap formed by burning of the combustible material, and the thermo-expansive tape can be inserted into the entire through- This is an efficient and economical metal pipe which has been insulated for the penetration of the building which can prevent natural ignition by heat by covering the heat insulating material with heat to prevent it because it is naturally ignited by heat. And a method for forming a refractory filling structure.

When the metal pipe penetrates through the fire protection compartment of the floor or wall of the building, the penetrating fire protection structure is maintained in the same way as the fire protection compartment in accordance with the Building Act [Article 14 (2) of the Standards on Evacuation and Fire Protection Structure of Buildings) . According to the test method of detailed operating guidelines of the Ministry of Land, Transport and Maritime Affairs and the Ministry of Land, Transport and Maritime Affairs, detailed rules of this regulation, the temperature of the penetrating material passing through the fire protection compartment is determined not to exceed 180K when measured from the back side of the fire circle.

Building regulations (for example, Article 40 of the Law, Enforcement Decree of the Building Act, and Ministry of Land, Transport and Maritime Affairs Notice (No. 2008-154) The walls and bottom of buildings require a structure that can withstand flames (1,049 ° C or more) for a certain period of time.

It is important to seal the penetration part in construction work as a measure to minimize the localization of the damage by preventing the smoke and flame from spreading rapidly to the adjacent room when a fire occurs in actual buildings. Therefore, the work to seal the penetration part according to the performance of the refractory structure is called "refractory filling work", and the state maintains the "accreditation system" that tests and certifies the refractory filling structure by the state. In order to be recognized as a fire-proof refill structure, the penetration part must pass the heat resistance test, and the fire resistance performance grade will be given to the accreditation body through a predetermined heat resistance test.

Mineral wool, ceramic wool, and silicon foam materials, which are inorganic materials used as fireproof fillers in construction work, are widely used as intermediate materials in refractory filling structures.

However, these filling materials themselves are excellent in flame retardancy, stretchability, lightness and the like depending on the products, but on the other hand, there is a fear of generation of dust due to thermal degradation, absorbency, abrasion and high density. Therefore, it has been known that there is a problem in using alone as a filler for fire protection treatment.

Plastic pipes are flammable, so when a fire occurs, a large amount of gas is released and a frayed pore is generated, which leads to diffusion of toxic gas and fire through the pore. Therefore, since the conventional rock face and the silicone foam alone do not have an expansion characteristic, there is a limit to fully cope with plastic pipe fire.

In addition, according to Utility Model Application No. 2005-0009274, there is disclosed an architectural fixture for fixing a pipe to a floor or wall penetration through a pipe, Since the granular fastener is installed in the bottom penetrating part first, the fireproof filling structure must be structured so as to be installed in parallel with the granular fastener.

In addition, metal pipes are used for various purposes such as hot water, heating and cooling, etc. In general, an inorganic insulating cover such as glass fiber is used as a heat insulating material to maintain the heat. In particular, the glass fiber insulation cover is used at a place where the risk of fire is a concern even though it is expensive compared with other organic insulation cover. However, considering 2 hours at 1050 ° C, which is the heating temperature of the fire resistance test, Which is a melting point of 400 to 600 ° C, and thus the refractory structure can not be maintained.

1 is a view for explaining a structure of a metal pipe for a penetration portion of a conventional building. In most cases where a refractory filling operation is not performed, as shown in Fig. 1, It is installed along the perforating part, and even if the surrounding of the thermal insulating material is filled with refractory mortar, mineral wool, glass wool, etc., the thermal insulating material is burned by the fire,

Therefore, if the insulating material is already installed along the penetrating portion, it is possible to complete the refractory filling work by removing the insulating material around the penetrating portion, filling the object with the incombustible material, and reinstalling the insulating material.

However, such a method has a problem that it is not an economical method because it is difficult to construct the insulation between the penetration parts and the construction cost is increased because the insulation work must be done again after completion of the work.

Therefore, the thermally expandable tape can be inserted between the heat insulating material and the penetrating sleeve in the upper part and the lower part, or in the case of the wall, to the left, right or part thereof, A metal pipe having a heat insulating portion for a penetration portion of a building which can prevent the natural ignition due to heat by inserting a gender tape into the entire penetration portion or attaching it to a part of the upper or lower portion, A method of forming a refractory filling structure on the surface of a substrate is required.

A method of forming a refractory filling structure on a metal pipe with a built-in thermal insulation for a penetrating portion of a building according to the present invention is characterized in that in order to make a hole through which the metal pipe (30) can pass through the bottom slab (10) (A) molding the sleeve (20) together with the bottom slab (10); (B) maintaining the warm water supply water in the metal pipe and surrounding the metal pipe (30) with a heat insulating material (40) in order to prevent water leakage due to condensation water in the case of cold water; A step (c) of inserting and attaching the thermally expansible tape (50) on the upper and lower portions of the heat insulating material (40) and the through sleeves (20) (D) covering the heat insulating material (40) with the heat shielding material (60) attached to the upper, lower, or part of the expansion tape; Respectively.

As shown in FIGS. 2 to 3, a flow of forming a refractory filling structure on a metal pipe that has undergone thermal insulation for a penetrating portion of a building will be described below.

First, the step (a) of forming the penetrating sleeve 20 together with the bottom slab 10 is carried out so as to form a through hole in the bottom slab 10 in which the metal pipe 30 can penetrate, The through-sleeve 20, which is a large pipe, is molded together with the bottom slab 10. Here, the through sleeve 20 is most preferably made of a plastic material, but may also be made of a metal material.

Secondly, as step (b) of surrounding the metal pipe 30 with a thermal insulating material 40, a metal pipe is used to maintain the hot water supply in the metal pipe and, in the case of cold water, (30). The insulating material 40 may be any one of an inorganic insulating material such as a glass fiber, a rock surface, a silica-based inorganic insulating material, a polyethylene foam foam, an EPDM foam, an EVA foam foam, It is one. Since the polyethylene foam (PE) foam has a low thermal conductivity and is excellent in thermal insulation effect and is a non-absorbent material, it does not deteriorate the insulation performance even after a long time, and also serves to prevent condensation and reduce vibration. EPDM: Ethylene Propylene Diene Monomer) is mainly used as an insulation material.

(C) attaching a thermally expansible tape 50 between the heat insulating material 40 and the penetrating sleeve 20 as a step (c), wherein a thermally expansible tape 50 is provided between the heat insulating material 40 and the penetrating sleeve 20, (50) in the upper and lower parts, or in the case of the wall part, the left and right parts. Here, the thermally expansible tape 50 can be more fully implemented by fitting the thermally expandable tape 50 into the entire penetrating portion, but since the thickness of the penetrating portion is mostly 100 mm or more, it is very difficult and costly to work, 50) is formed with a thickness of 0.5 to 15 mm and a width of 5 to 75 mm, so that the work is efficient and economical. Considering that the thickness of the heat insulating material of the metal pipe 30 is 5 to 60 mm, the thermally expansible tape 50 has an expansion characteristic of 2 to 100 times. Further, the thermal expansion tape (50) is inserted into the whole of the penetration portion or attached to a part of the upper, lower, left, and right sides.

Fourth, the step (d) of covering the heat insulating material 40 with the heat shielding material 60 is carried out so that the heat insulating material 40 surrounding the metal pipe 30 is naturally ignited by heat. A thermal barrier 60 covering the upper, lower, or part of the expansion tape is overlaid to prevent natural ignition by heat. Here, the refractory filling structure of the metal pipe is a structure in which even when the fireproof compartment penetration portion is sealed by the fireproof or confirmed method, the metal pipe transmits heat to the back surface where the fire occurs, And the fire spreads. The temperature of the heating furnace tested in KS F ISO-10295 reaches 1049 ° C in 2 hours and the surface temperature of the metal pipe in the 2.5 cm portion of the heating furnace reaches 250 ° C to 600 ° C according to the diameter of the metal pipe. Accordingly, since the heat insulating material 40 of the metal pipe on the back surface is spontaneously ignited by heat, it is possible to prevent the natural ignition by heat by covering the heat insulating material 60 with the performance of which is confirmed to prevent it. By this method, a thermally expansible tape 50 is attached to the inside of the heat shielding material having a thickness of 0.1 to 50 mm and a length of 50 to 500 mm to block the diffusion of fire by spontaneous ignition of the heat insulating material due to high temperature heat transfer and filling of the melted down air gap will be. The heat shielding material 60 is one of ceramic wool, ceramic paper, mineral wool, glass wool, polyester fiber, FRP, aluminum plate, and iron plate.

The method of forming the refractory filling structure on the metal pipe that has been subjected to the thermal insulation for the penetration portion of the building of the present invention as described above can be applied to a metal pipe penetrating the fire partition of a floor or wall of a general building as well as an apartment, will be.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
