Roof surface fire prevention measure mainly contains and adopts surface spraying fireproof paint and two kinds of modes of PLASTIC LAMINATED are set at present.Fireproof paint is painted on the outside of protected base material, has the feature of flame retardancy, low heat conductivity, but fireproof paint is constructed and roof ambient influnence is large, easily comes off, and causes operation maintenance cost higher.PLASTIC LAMINATED is as another kind of interior decoration fireproof building material; taking metal sheet (Lv Ban ﹑ Bu rust Gang Ban ﹑ Cai look Gang Ban ﹑ titanium Xin Ban ﹑ titanium plate, copper coin etc.) as panel; what halogen-free flameproof was mineral-modified fills out core material is sandwich layer; a kind of fireproof sandwich style sandwiched plate that hot pressing is composited; its thickness is larger; and and protected base material between the normal fixed gap that exists, be difficult to cooperative bearing, and the thermal and insulating performance of sheet material is poor.
In sum, although current existing roof structure can meet the requirement of current specifications, remain and can improve part at aspects such as fireproof performance, durability, thermal and insulating performance, intensity.Given this, for improving fire prevention, the thermal and insulating performance of roof structure, for the deficiency in existing structure, need at present invention one badly and there is the features such as thermal and insulating performance is good, supporting capacity is high, speed of application is fast, operation maintenance cost is low, can be used as the Novel composite water fire-proof and water-proof curved roof structure that roof fireprotection layer uses.
Summary of the invention
The purpose of this utility model is, invention one has the features such as thermal and insulating performance is good, supporting capacity is high, speed of application is fast, operation maintenance cost is low, can be used as the Novel composite water fire-proof and water-proof curved roof structure that roof fireprotection layer uses.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of compound fire-proof and water-proof curved roof structure, the upper and lower that it is characterized in that roof structure layer all arranges thermal insulation separation thermosphere, wherein, waterproofing course and finial layer are set on the thermal insulation separation thermosphere above deck, between thermal insulation separation thermosphere below deck and lining cutting bottom, fireprotection layer is set, below lining cutting bottom, plate is set at the bottom of architectural surface;
Waterproofing course can adopt geomembrane or geotechnological splash guard;
Described fireprotection layer is built and is formed by fire-proof light mortar, lays reinforced mesh reinforcement layer in it; Described reinforced mesh is layed in 1/2 thickness place of fireprotection layer, can adopt cold-rolled ribbed steel fibric, cold-drawn plain bar net or hot rolled ribbed steel bar net, and reinforced mesh is identical with roof curved surface radian;
Described thermal insulation separation thermosphere can adopt insulated foam coating, extrusion molding insulating board, clad aluminum foil thermal insulating coiled material, glass fabric; Between thermal insulation separation thermosphere and deck, adopt alite paste to paste;
Two curved roof intersections arrange special-shaped gutter, and special-shaped gutter is connected with the gutter of building both sides.
The utlity model has following feature and beneficial effect:
(1) at upper surface and the soffit of deck, thermal insulation separation thermosphere is all set, both can have played good heat insulating effect, deck and thermal source can be separated, improve the ability of roof structure opposing high temperature, fire simultaneously.
(2) the fire-proof light mortar that fireprotection layer is built employing has good insulating properties, and the reinforced mesh arranging in mortar can strengthen plasticity and the cracking resistance of fireprotection layer, can prevent that mortar from brittle fracture occurring in the time of high temperature.
(3) special-shaped gutter can utilize the natural curved surface that two surface intersections form, and can in time roof ponding be got rid of, and has improved the durability of structure.
