Specific embodiment
Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will Understand, the following example is merely to illustrate the present invention, and is not construed as limiting the scope of the invention.It is not specified in embodiment specific Condition person carries out according to conventional conditions or manufacturer's recommended conditions.
The present invention provides a kind of wallboard, the lightweight coagulation being set among two blocks of side plates including two blocks of side plates and fixing clamp Soil layer.
Side plate can be bonded completely with lightweight concrete layer or the junction of wallboard and other wallboards have by side plate with Lightweight concrete layer is not exclusively bonded the tenon structure of formation, realizes the connection between wallboard.Using lightweight concrete layer as middle layer, Both sides are side plate, can improve the brittleness of side plate, are improved since the stress that building settlement generates makes side plate drawing crack.Two blocks of side plates The mixed of composite demand can be made using the product of different densities according to the demand of performance with the lightweight concrete layer of middle layer Solidifying soil prefabricated component.The wallboard can be processed directly, and scene splicing, avoids construction site with transporting construction The problem of dust is excessive, pollutes environment, improves construction efficiency.
In the present invention, one is preferably carried out in mode, and a side end face of lightweight concrete layer protrudes from the end of two blocks of side plates Face forms tenon, and the other side sunken end face of lightweight concrete layer forms the tongue-and-groove with tenon cooperation in the end face of two blocks of side plates. Side plate can be bonded completely with lightweight concrete layer or the junction of wallboard and other wallboards has by side plate and lightweight coagulation Soil layer is not exclusively bonded the tenon structure of formation, realizes the connection between wallboard.The wallboard can be processed directly, transported and built The splicing of construction ground scene is built, it is excessive to avoid construction site dust, the problem of polluting environment, improves construction efficiency.
In the present invention, one is preferably carried out in mode, and lightweight concrete layer includes the following raw material according to parts by weight: water 400-500 parts of mud, 270-330 parts of the inorganic porous material particle of+8 mesh of mistake, mistake -8~+16 mesh inorganic porous material particles 420-480 parts, 360-420 parts of the inorganic porous material particle and optional auxiliary agent of -16 mesh of mistake.
It should be noted that mesh, through the unit frequently as material particle size or mesh size.Mesh number is bigger, indicates particle It is thinner, it is usually used in the quantifier of laboratory sample broke granularity.In general, the aperture mesh number * (micron number)=15000.For this For the technical staff of field, "-(negative sign) " is added before the Arabic numerals of mesh number often to indicate that particle can be by selected Sieve, "+(positive sign) " indicate particle cannot pass through selected sieve.Such as: " -80 mesh " then indicates that of 80 meshes can be passed through Grain；"+120 mesh " then indicates that the particle of 120 meshes cannot be passed through.
There is inorganic porous material particle porous structure, usual water absorption rate to be greater than 9%, and section is coarse unglazed, and product is mechanical Intensity and chemical stability are higher, and High anti bending strength, wear-resistant, acid and alkali-resistance, non-discolouring, the service life is long.+ 8 meshes were used respectively Inorganic porous material particle, mistake -8~-16 mesh of+16 mesh inorganic porous material particles and mistake inorganic porous material particle All or part of sandstone replaced in concrete as aggregate, by the inorganic porous material particle for compounding totally three kinds of different-grain diameters Instead of the coarse aggregate and fine aggregate in concrete, so that lightweight concrete has preferable specific gravity and mechanical performance.In order to avoid Coarse aggregate particle is excessive, therefore wherein the inorganic porous material particle preferable particle size of+8 mesh of mistake is less than 2cm.Above-mentioned raw materials can The overall weight of concrete is effectively reduced, lightens the load, it is many with traditional sand-stone concrete light specific gravity, and due in concrete Heat preserving heat insulating noise insulation performance containing porous inorganic porous material particle, therefore concrete is superior to traditional sand-stone concrete.
