Abstract
The utility model relates to a gypsum shaving board light steel joist fire-wall. The utility model is characterized in that each of the both faces of the fire-wall is provided with two layers of gypsum chipboard; the middle of the fire-wall is light steel joists and rock wool; the interval between the vertical joists of the light steel joists is 610 mm; the thickness of the gypsum chipboard on the surface layer is 12 mm; the thickness of the gypsum chipboard on the inner layer is 10 mm; the thickness of the light steel joists and the rock wool in the middle of the fire-wall is 100 mm. The utility model has the advantages that the structure is simple; the layers of the panel of the fire-wall is reduced; the number of light steel joist joists is reduced; the cost is low; the construction difficulty is lower; the requirement of the national building fire protection normative standard is achieved; the fireproof time is three hours according to tests; the effects of heat insulation and acoustic insulation are good.
Description
The utility model belongs to fire stop, particularly a kind of gypsum particle board lightgage steel joist fire stop.
Present existing lightgage steel joist Thistle board and its structure of other plasterboard partition wall are little except that intensity, the moisture resistance, sound insulation difference, poor performance aspect fire prevention.As reaching fire protection requirement, need to use multilayer panel and more complicated structure just can reach basic fireproof performance.But the big cost height of its complex structure weight of such partition wall.And along with the high-rise high-rise building of the continuous development of builing industry continues to bring out thereby the fire-fighting work of highrise building has been proposed new problem and the requirement of Geng Gao.Country was united by the Ministry of Public Security, the Ministry of Construction and has issued the building fire protection standard and be mandatory execution rules on October 1st, 95 for this reason.The spacing of the lightgage steel joist of at present all common walls all is that 400mm but this spacing do not reach the Ministry of Public Security, the Ministry of Construction and unite and issued the building fire protection standard.Sign in this kind situation, invented lightgage steel joist gypsum particle board rock wool through more than a year repetition test and research and added heart light fire-proof partition.
The purpose of this utility model provides a kind of at this gypsum sheet material of gypsum particle board can reach fire prevention 1-3 hour with individual layer or double-deck gypsum particle board structure, and cost is low, simple in structure, the gypsum particle board lightgage steel joist fire stop being convenient to install.Overcome existing lightgage steel joist Thistle board and other plasterboard partition wall intensity is little, moisture resistance, sound insulation are poor, and the shortcoming of fireproof performance difference.
The purpose of this utility model is to realize like this.
A kind of gypsum particle board lightgage steel joist fire stop, it is characterized in that: the two sides of fire stop respectively is two-layer gypsum particle board, surface layer and internal layer, the centre is lightgage steel joist and rock wool, its lightgage steel joist has along the top keel with along the ground keel, between top keel and ground, edge keel is vertical keel, is inserted with horizontal keel between the vertical keel, and the spacing between the vertical keel is 600mm～620mm.
Optimal spacing between the vertical keel is 610mm.
Surface layer gypsum particle board thickness is 10～15mm, and internal layer gypsum particle board thickness is 8～15mm, and middle lightgage steel joist and the thickness of rock wool are 50～150mm.
Surface layer gypsum particle board optimum thickness is 12mm, and internal layer gypsum particle board optimum thickness is 10, and middle lightgage steel joist and rock wool optimum thickness are 100mm.
The utility model has the advantages that:
This kind structure has not only reduced the number of plies of fire wall panel, has reduced the quantity of lightgage steel joist, has reduced construction costs, has reduced difficulty of construction, intensity and has reached national building fire protection codes and standards, and played good insulation, soundproof effect.It is the simplest and the longest light partition wall of fire prevention time of present structure.
Below in conjunction with description of drawings embodiment:
Fig. 1 is a gypsum particle board lightgage steel joist fire stop schematic diagram
Fig. 2 is a gypsum particle board lightgage steel joist fire stop vertical sectional view
Fig. 3 is a gypsum particle board lightgage steel joist fire stop horizontal cross
Fig. 4 is gypsum particle board lightgage steel joist fire stop centre keel and horizontal keel connection diagram
A kind of gypsum particle board lightgage steel joist fire stop, the light fire-proof partition two sides respectively is two-layer gypsum particle board, surface layer 1 and internal layer 8, the centre is lightgage steel joist 2 and rock wool 3, its lightgage steel joist has along top keel 4 with along ground keel 5, between top keel and ground, edge keel is vertical keel 6, is inserted with horizontal keel 7 between the vertical keel, and the spacing between the vertical keel is 600mm～620mm.Optimal spacing between the vertical keel is 610mm.Its lightgage steel joist than the 400mm of the lightgage steel joist spacing of common wall be increased to 610 so every square metre of wall just can reduce the heat transfer structure.
The gypsum particle board thickness of surface layer 1 is 10～15mm, and internal layer 8 gypsum particle board thickness are 8～15mm, and middle lightgage steel joist and the thickness of rock wool are 50～150mm.
The gypsum particle board optimum thickness of surface layer is 12mm, and internal layer gypsum particle board optimum thickness is 10mm, and middle lightgage steel joist and the optimum thickness of rock wool are 100mm.And gypsum particle board and the rock wool very little material that is thermal transmittance.Thereby the heat transfer member lightgage steel joist eases down to minimum number and is delivered to the body of wall another side with the least possible lightgage steel joist that passes through of flame heat regulating that guarantees the body of wall one side in guaranteeing the maximum stiffness scope of body of wall.Body of wall is not all destroyed by heat energy, thereby play fire prevention, fire insulation effect.
Gypsum particle board is a kind of nonflammable material, is not fire proofing material, and therefore (900 ℃-1200 ℃) can only guarantee in 20-40 minute not bad by the high temperature combustion under raging fire high temperature.Thereby 2 layers of 10-12mm sheet material is bad by row fire, high temperature combustion in 60-180 minute, and to require unexposed surface temperature not surpass 140 ℃ of degree be impossible at all.
Study the method that we have used filling rock wool in the middle of two-layer gypsum particle board panel through repeated multiple times for this reason.Since rock wool has good refractoriness and very low thermal transmittance thus after the gypsum particle board of side towards the fire is by raging fire high temperature destruction rock wool just be exposed in the raging fire high temperature; rock wool has not only effectively resisted 900 ℃-1200 ℃ high temperature, because its low heat transfer performance has also effectively been protected effective control of the gypsum particle board surface temperature of carrying on the back fiery face.(in 140 ℃)
This kind structure has not only reduced the number of plies of fire wall panel, has reduced the quantity of lightgage steel joist, has reduced construction costs, has reduced difficulty of construction, intensity and has reached national building fire protection codes and standards, and played good insulation, soundproof effect.It is the simplest and the longest light partition wall of fire prevention time of present structure.This gypsum particle board lightgage steel joist fire stop of test through the Tianjin Fire Research Station reaches three hours fire resistance property.
