Technical field
The utility model belongs to building field, relates to the waterproof thermal-insulated sheet material of a kind of concrete base building, particularly realizes a kind of ultralight matter cement-based waterproof heat preservation plate material for building of insulation, fire prevention, water-proof function.
Background technology
Cement foaming material is with it does not fire, excellent properties such as insulation, lightweight causes industry extensive interest.But it is by no means easy to reach the building materials practical standard.The foam cement sheet material dry volume density that particularly is applied to exterior-wall heat insulation is many at 300kg/m
3More than, only can reach 200kg/m through great efforts
3About, can reach reluctantly coefficient of temperature conductivity requirement, make foam cement sheet material possess the close coefficient of thermal conductivity of organic heat-insulating sheet material.But along with unit weight its intensity that descends descends significantly, the result has satisfied the requirement of national building energy conservation 65%, but can not reach carrying and measuring body basic mechanical index.This also can't practical application in construction.
For the ultralight cement foaming material is used in engineering, technology such as coating outside a lot of people adopt outside foaming body.The material that adopts is the rapid setting cement mortar.The prior art coating thickness is thicker.Foam cement sheet material is very heavy, adds that clad weight is unfavorable for on-the-spot constructing operation more.If foam cement body unit weight can be controlled at 150kg/m
3Below, coefficient of thermal conductivity can be controlled and the polyphenyl plate order of magnitude, and then Yi Shang technical scheme-cement based composite insulation boards just might be applied to the job site.In the market because of ultralight cement foaming material intensity is low, the coefficient of thermal conductivity instability, the sheet material of making based on the ultralight cement foaming material still has very big difficulty.
Now, the inventor has solved up to standard and two key issues of coefficient of heat conduction stability of unit weight of the cement of giving out a contract for a project.The problem of design light cement base waterproof thermal-insulated sheet material for building is brought into schedule again.
Summary of the invention
The utility model has designed the waterproof thermal-insulated sheet material of concrete base building for the waterproof that solves light cement base heat preservation plate material for building, the problem of insulation.Reached the effect that insulation, waterproof, fire prevention and ultralight matter are easy to construct by means of shell waterproof, reinforcement.
The utility model for realizing the technical scheme that goal of the invention adopts is: the waterproof thermal-insulated sheet material of a kind of concrete base building, comprise heat preservation core layer and waterproof shell in the structure, importantly: described waterproof shell is the hollow slab type structure, heat preservation core layer is arranged in the housing, and the reinforcing rib of panel passes on two corresponding panels that heat preservation core layer is connected in the waterproof shell in the waterproof shell.The thickness of described waterproof cover deck panels is 2-10mm.
The beneficial effects of the utility model are: place the waterproof shell of hollow slab type structure based on the heat preservation core layer of foam cement, better insulation, flameproof effect are arranged like this; The waterproof shell is made the closed shell structure, has blocked the conduction of heat between the cement panel on the one hand, makes flameproof effect better, has avoided seepage on the other hand, makes waterproof effect better; Difference waterproof cover deck panels thickness of structure according to practical application is set to 2-10mm, can reduce the weight of whole building water-proof heat preservation plate material like this, is convenient to constructing operation; Reinforcing rib passes on two corresponding panels that heat preservation core layer is connected in the waterproof shell in the waterproof cover deck panels structure, reinforcing rib the intensity and the compressive resistance that can increase whole waterproof thermal-insulated sheet material be set, make heat preservation plate material firmer.
Below in conjunction with accompanying drawing the utility model is elaborated.

The specific embodiment
Referring to Fig. 1, the waterproof thermal-insulated sheet material of a kind of concrete base building, comprise heat preservation core layer 2 and waterproof shell 1 in the structure, key is: described waterproof shell 1 is the hollow slab type structure, heat preservation core layer 2 is arranged in the housing, and the reinforcing rib 4 of upper and lower panel passes on two corresponding panels that heat preservation core layer 2 is connected in waterproof shell 1 in waterproof shell 1 structure.Enclosed like this hollow slab type structure has better insulation, flameproof effect, uses the utility model in the engineering, has avoided the conduction of heat between sheet material and the sheet material, makes flameproof effect better; Reinforcing rib 4 the intensity and the compressive resistance that can increase whole heat preservation plate material be set, make heat preservation plate material firmer.
The thickness of described waterproof shell 1 is 2-10mm.Can reduce the weight of whole building water-proof heat preservation plate material like this, be convenient to constructing operation.
In waterproof shell 1 structure, be provided with uniform strengthening rib strip 3 on the side plate, and the shape of cross section of strengthening rib strip 3 is circular-arc.The setting of strengthening rib strip 3 has reduced the suffered impact force of water-proof heat-insulating slab edge plate on the side plate.
Reinforcing rib 4 is cylindric or lamellar, or be designed to that the thin plate of horizontal, vertical intersection forms latticed.
Add netted cushion coat between waterproof shell 1 and the heat preservation core layer 2.Netted cushion coat the cushioning effect of having brought into play stressed is set, strengthened the compressive resistance of waterproof thermal-insulated sheet material again.
Embodiment of the present utility model in the specific implementation, heat preservation core layer 2 adopts ultralight foam cement core, so-called foam cement core is with cement and other inorganic material and Admixture, add the water stirring then and be slurry, subsequently blowing agent and water being added foam and the slurry that foaming machine produces stirs, add an amount of hydrogen peroxide again and stir after-pouring rapidly in mould, promptly become ultralight foam cement core after the sclerosis, can add granular polystyrene more in addition, expanded perlite, further reduce dry volume density and coefficient of thermal conductivity, can improve the tensile strength of ultralight foam cement core and the flowability of reduction foaming slurry simultaneously.Coefficient of thermal conductivity≤the 0.035w/m.k of the ultralight foam cement core that can produce like this, dry volume density is accomplished below the 60kg/m3, has satisfied the latest requirement of current building energy-saving 65%.
