Abstract

The present invention relates to a fireproof partition structure as a nonbearing wall and a construction method thereof. More specifically, under a state where continuous insertion of an internal panel intobetween an upper runner and a lower runner is done by filling mineral wool in a steel sheet and comprising the internal panel having a male and female type insertion part at both sides thereof, a flame-retardant gypsum board and a fireproof sheet are attached to a front and a rear of the internal panel, and a flame-retardant finishing panel is fixed and formed onto a surface of the flame-retardant gypsum board, and thus the fireproof partition wall is constructed using the internal panel after the continuous insertion of the internal panel. Thus, the fireproof partition wall can be constructed very rapidly and simply. Because boundaries of the internal panel, the flame-retardant gypsum board, and a flame-retardant finishing panel are not overlapped with each other, the fireproof partition structure of the present invention provides excellent fireproof performance by blocking the transmission of heat or flame through gaps therebetween. The present invention can maintain mineral wool or the like filling the internal panel to be uniformly filled over the entire partition wall by fixating the flame-retardant gypsum board using a fixing bolt or the like and preventing the flame-retardant gypsum board from sagging or being compressed. The method also has the effect of allowing the construction of a simple and beautiful partition wall because the upper runner and the lower runner to construct the partition wall are not protruding and exposed to the outside.

Description

[0002] Fireproof partition structure and its construction method [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a fireproof partition structure of a non-bearing wall type installed in various buildings, more particularly, In the case where a fire is generated in the space insulated by the fireproof partition due to the fixing of the fireproof gypsum board on the front and rear sides of the inner panel and the finishing panel in which the fireproof gypsum board is embedded in the steel sheet, It is of course possible to effectively block the heat transfer and flame transmission and to greatly improve the workability of the refractory partition wall.

The 'Fire Rescue Structure' defined by the Building Law means the structure confirmed by the head of the Korea Institute of Construction Technology and confirmed by the fire resistance performance. The fire resistance performance standard is determined according to the height of the building, the number of floors, It is stipulated that it should be a refractory structure capable of withstanding.

In addition, the fireproof partition is used as an inner wall for partitioning or isolating the inner space of a general building or a prefabricated building, so that a building permit can be obtained only if it has a fireproof performance for each use.

On the other hand, a partition used as a non-bearing wall is generally called "SGP partition", that is, a steel plate is attached to the outside of the gypsum board. However, the existing SGP partition does not satisfy the fire resistance performance required by Korea Institute of Construction Technology This is because, when heat is applied from one side of the partition, the gypsum board alone can not effectively block the heat from being transferred to the other side. In particular, it is used as a frame for forming a partition or as a column for connecting a partition and a partition There is a problem in that it can not pass the fire resistance test because the heat is transferred through the C-type stud.

Accordingly, as in the case of Japanese Patent Registration No. 10-0899597, a separate fireproof partition is attached to the front and rear surfaces of the C-shaped stud which constitutes the inner skeleton, and the fireproof fiber board is attached to the outer side of the fireproof gypsum board, A flame-retardant fiber board and a flame-retardant fiber board are disposed on the outer side of the flame retardant fiber board. The flame retardant fiber board and the flame retardant gypsum board are disposed on both sides of the flame retardant gypsum board. There has been found a fireproof partition and a construction method thereof in which a gypsum board is further adhered so that the heat transfer to the other space and the transmission of the flame can be effectively blocked when a fire occurs in one space separated by the partition.

However, in the above-described refractory partition and the partition wall constructed using the same, the flame-retardant gypsum board and the flame retardant fiber board are simply attached to the existing C-type stud, and then the partition wall is constructed using the existing flame retardant gypsum board and the flame retardant fiber board So that the heat and flame of high temperature can flow into the inside of the partition wall through the gaps between the flame-retarding gypsum boards, and it can leak out to the other side, which is a fundamental solution.

That is, when the flame resistant gypsum board and the flame retardant fiber board are attached to the surface of the C-type stud as described above and the flame retardant gypsum board and the flame retardant fiber board connecting the flame retardant gypsum board and the flame retardant fiber board are fixed to each other, there will be a gap between them. Heat or flame can escape to the other space through the inside of the partition wall and it takes considerable effort and time to attach the flame retardant gypsum board and the flame retardant fiber board to the surface of the C type stud. Because it is very uneconomical.

In addition, even when the existing refractory partition wall is constructed, the lower runner and the upper runner are fixedly installed on the floor and the ceiling of the room, and the C-type stud is measured and fixed between the upper and lower runners at regular intervals Since the flameproof board and the flame retardant fiber board must be attached and fixed to the surface of the C-type stud in a state in which the C-type stud is formed, it is necessary to pay considerable care and effort in fixing the C- It is difficult to obtain a firm fixing force of the flame retardant gypsum board and the flame retardant fiber board which are fixedly installed.

Further, when the spacing between the C-type studs is not uniform and the ends of the two gypsum boards are not positioned exactly at the center of the C-type studs and are fixed to one side, the gap between the neighboring gypsum boards The flame or the heat can flow into the partition wall more rapidly through the partition wall, thereby failing to function as an efficient fire partition wall.

In the case of conventional refractory partitions, a mineral wool (or glass wool) charged between flame-retarded gypsum boards positioned before and after a partition wall, that is, a C-type stud, has a density of 24 to 140 K and a thickness of 50 to 100 mm In the case of mineral wool, since it is filled with a height of 2.5 ~ 3.0m in the narrow gap of the front and back flame-retarding gypsum boards, the deflection gradually occurs with time. As a result, the upper part of the refractory partition wall is filled with mineral wool And the lower end of the refractory partition wall is filled with the mineral wool in a high density state, so that the refractory performance is not uniformly exhibited on the entire surface of the refractory partition wall.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems described above and it is an object of the present invention to provide an internal panel in which a mineral sheet is filled in a steel sheet and both side ends are provided with female and male fittings, The flame retardant gypsum board and the flame retardant fiber sheet are fixed to the front and rear surfaces of the inner panel and the flame retardant finish panel is fixed to the surface of the flame retardant gypsum board,

It is possible to easily fix the flameproof board and the flameproof panel by using the continuously inserted inner panel, so that the construction of the flameproof panel can be performed more quickly and easily, and the boundary line between the inner panel and the flameproof board and the flame- Provided is a method for constructing a fireproof partition structure having a flame retardant structure that can be more stably fixed by staggering it so as not to overlap with each other, and the upper runner and the lower runner are not exposed to the outside. The present invention has the object of the present invention.

According to an aspect of the present invention, there is provided an electronic device comprising: a front panel having a front surface and a rear surface; And a flame-retarding gypsum board is closely fixed to the outer surface of the flame-retarding gypsum board, and a flame-retarding gypsum board is fixedly formed on the outer surface of the flame-

Fixing the lower runner and the upper runner to the floor and the ceiling inside the building; Continuously inserting the inner panel between the lower runner and the upper runner; Tightly fixing the flameproof board to the outer surface of the continuously installed inner panel; Fixing the flame-retarding finish panel to the outer surface of the flame-retarding gypsum board; And a step of fixing the gap finishing material between the flame-retarding panels by interposing the gap finishing material between the flame-retarding panels. The object of the present invention is thus achieved.

The present invention is not limited to installing C-type studs or the like at regular intervals, but is used to construct a fireproof partition wall by using the inner panel after continuous insertion, so that the construction of the fireproof partition wall can be performed very quickly and easily , Since the boundary between the inner panel and the flame-retarding gypsum board and the flameproof panel does not overlap with each other, the flame or heat can be prevented from being transmitted through the mutual clearance, and the fireproof performance is excellent. Can be maintained in a state of being filled uniformly over the entire upper and lower portions of the partition wall since it is not sagged or compressed while being restrained by fixing bolts or the like in the process of fixing the flameproof board. Since the runner is not projected or exposed at all A more concise and to the construction of elegant partition wall to be effective.
