Abstract
The utility model relates to a compound board for building, which adopts the prior art of a three-layer structure composed of two pieces of the surface plywood on the both sides of the structure and the heat preservation core material clamped in the middle of the structure. The differences of the utility model are that the two pieces of the surface plywood are changed into steel fibre concrete boards, and the two pieces of the surface plywood are connected with each other and form integration by using steel strips to surround the two pieces of the surface plywood and welding a girder on the steel strips which surround the two pieces of the surface plywood. Heat preservation material, which is clamped between the two pieces of the surface plywood, is used as core material. The two pieces of the surface plywood and the core material of the utility model are not bonded together, so shearing force which can destroy the structure of the compound board is not generated between the two pieces of the surface plywood and the core material in the process of use. Besides, the steel fibre concrete boards and the girder for connecting are used, so the mechanical property of the compound boards is improved, and the heat preservation effect and the waterproof effect of the compound boards are ensured.
Description
The utility model belongs to the building unit technical field.
At present, more widely used composite plate has the patented technology " Sa Moni plate " and the BP technology " Si Tailuokang plate " of Japan.Two kinds of plates all are to be bonded together by the surface layer of both sides and the core integral body of centre." Sa Moni plate " is to be surface layer with the asbestos cement thin plate, and it is core that light foam concrete adds the alkali resistant fiber.And " Si Tailuokang plate " is surface layer with the steel wire cement plate, and the polystyrene concrete is a core.These two kinds of plates are mainly used in body of wall and roof.This type of plate top layer is main bearing bed, and the effect of interlayer is that the surface layer plate on both sides is strutted, and improves the strength and stiffness of entire plate with this, thereby reaches weight reduction, improves heat insulation effect, improves the mechanical structure of building and the purpose of reduction cost.But core that bonds together and surface layer plate will produce bigger shear strain when stressed, bonding effect was lost efficacy, the phenomenon that core, face are separated occurs, the overall structure performance of plate is obviously reduced, cause the surface layer cracking, make it to lose waterproof and insulation effect.
The purpose of this utility model be select for use high-strength surface layer plate to form panel and core needn't coherent composite plate, make it between panel and core, not produce shearing, thereby eliminate the unfavorable factor on the composite plate internal construction.
It is to select for use steel fiber reinforced concrete slabs as the surface layer plate that technology of the present utility model constitutes, enclose with the band ladle around the surface layer plate, two chunk facing plates adopt the mode of steel truss to be consolidated relatively, clamping core between it (polystyrene foam plate, or other building thermal insulation materials commonly used).
Adopt effect of the present utility model to be: because panel adds steel fibre, thereby improve concrete cracking resistance mechanical property greatly, can make slim, the surface layer plate of high-strength compound plate.This is because steel fibre has higher modulus of elasticity and homogeneous deformation performance, also has the big and good advantage of cement-bonded performance of specific area simultaneously, is in two dimension again disorderly to distribution in concrete, therefore has the effect that very strong prevention crack produces.Owing to be not coherent between panel and the core, therefore do not form active force again, eliminated inner unfavorable factor.It is not impaired with core in use to keep the surface layer plate not ftracture, and has excellent waterproof and heat-insulating property all the time.
Accompanying drawing is a schematic diagram of the present utility model.
Implementation process of the present utility model is: at first give system steel fibrous concrete surface layer plate 1, be furnished with high-strength steel silk screen (steel wire diameter is 2-4mm, and the steel wire spacing is 200mm) in the concrete slab.In concrete, infiltrate the steel fibre of volume fraction 1%-2%, the expansion agent of the 13%-15% of adding cement weight and the super plasticizer of 0.75%-1.2%.The thickness of surface layer plate is 15mm, and the length of side is the square about 1500mm.Also can select it long, wide size according to the needs of reality building.There is the wide band stirrup 2(of 15mm when giving the system concrete slab, will be with steel to put into template simultaneously around the plate).Select for use the thick polystyrene foam plate of 50mm-100mm as core 3, be cut into and the surface layer plate is onesize is clipped between the two chunk facing plates, be welded on the band steel around the two chunk facing plates, make it to form the truss 4 that connects two chunk facing plates with short steel plate.Steel fibre light type composite panel of the present utility model is promptly manufactured and is finished.
