Abstract
The invention discloses a thermal-insulating fireproof structure of a floor slab deformation joint. The structure is composed of a floor layer (1), a leveling layer (2), a floor slab (3), a metal cover plate (4), a stainless-steel sliding bar (5), a fixing piece (6), expansion bolts (7), a waterproof layer (8), a fireproof layer (9) and the deformation joint (10). The structure has the advantages that the deformation joint is provided with thermal-insulating fireproof materials with the duration of fire resistance larger than 1.5 h, so that the deformation joint meets the requirement for the duration of fire resistance of first-fire-resistance-rating floor slabs; the heat transfer coefficient reaches 0.5 w/m<2>*k, so that the deformation joint meets the requirement for the limit value of the heat transfer coefficient of heating or non-heating floor slabs; the waterproof layer can prevent water from flowing to downstairs; the structure is easy to construct, economical and practical.
Description
Technical field
The present invention relates to a kind of building deformation seam structure, relate in particular to a kind of insulated fire structure of Floor Slab Deformation seam.
Background technology
The structure of Indoor environment Floor Slab Deformation seam at present, lack fire protection construction or have fire protection construction but can not meet the fire endurance that floor specifies, once building breaking out of fire like this, deformation joint just becomes weak link, cause that the intensity of a fire spreads along deformation joint, results in greater loss.Once especially in the time that deformation joint is crossed over fire compartmentation, the condition of a fire spreads along deformation joint, will cause another one fire compartmentation to catch fire, and causes unnecessary loss.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, a kind of insulated fire structure of Floor Slab Deformation seam is provided.To achieve these goals, technical scheme of the present invention is: a kind of insulated fire structure of Floor Slab Deformation seam, is made up of tier (1), leveling layer (2), floor (3), metal cover board (4), stainless steel slide bar (5), fixture (6), expansion bolt (7), waterproofing course (8), fireprotection layer (9), deformation joint (10).
The invention has the beneficial effects as follows: adopt said structure, deformation joint is provided with heat preservation fireproofing material, its fire endurance is greater than 1.5 hours, meet the floor fire endurance requirement of one-level fire resistance rating building, thermal transmittance reaches 0.5w/m2.k, has met heating and the not thermal transmittance limit value requirement of heating floor, and waterproofing course can stop water to flow into downstairs, construction is simple, economic and practical.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1-tier, 2-leveling layer, 3-floor, 4-metal cover board, 5-stainless steel slide bar, 6-fixture, 7-expansion bolt, 8-waterproofing course, 9-fireprotection layer, 10-deformation joint.
Detailed description of the invention
As shown in Figure 1, above reinforced concrete floor, establish 20 millimeters thick 1:3 cement mortar screeding layers, lay 10 millimeters thick ground vitrified tiles above, deformation joint, on tier, there is stainless steel cover plate, surface is made fluorine carbon and is sprayed paint, cover gap, there is stainless steel slide bar below, spacing is 500 millimeters, heat insulating material is 200 millimeters thick A1 level extruded polystyrene warming plates, extruded polystyrene warming plate density is 32kg/M3, coefficient of thermal conductivity is 0.3W/M.K, extruded polystyrene warming plate two ends are firm with building sealant and floor bonding, waterproofing course is 1 millimeters thick corrosion resistant plate, fix by expansion bolt and floor, fixture is fixed by expansion bolt and floor, expansion bolt is 300 millimeters of 6 millimeters of spacing of diameter.
