Steel Space structure light thermal-insulating integrated board
Technical field
The utility model belongs to technical field of buildings, particularly a kind of Steel Space structure light thermal-insulating integrated board.
Background technology
The plane generally with triangular element or space structures that truss is made up of straight-bar.Under load action, truss member mainly bears axial tension or pressure, thereby can make full use of the intensity of material, in the time that span is larger, comparable solid web girder is saved material, alleviate deadweight and increase rigidity, therefore be applicable to compared with the load-carrying members of large span and tall and slender structure, as roof truss, bridge, power transmission line column, satellite launching tower, hydraulic gate, gantry etc.
In truss not all rod member all the trussed construction in same plane be called space truss.Plane frame is mainly used in the plane structures such as roof truss, need become space structures with other framework, and space truss is mainly used in the space structures such as pylon, and independence is better.At present, mostly existing light plate is the main bearing member using steel frame as plate, the packing material using foaming perlite concrete or foamed concrete as plate, and product deadweight is larger, and anticorrosion, insulation, effect of heat insulation are poor.
Summary of the invention
The utility model is in order to make up the defect of prior art, and a kind of simple in structure, Steel Space structure light thermal-insulating integrated board that overall performance is good is provided.
The utility model is achieved by the following technical solution:
A kind of Steel Space structure light thermal-insulating integrated board, comprise two stress frames that opening is relative, it is characterized in that: the steel wire net rack by space truss type between described stress frame connects, fill insulant material between steel wire net rack, the top layer up and down of steel wire net rack is coated with light weight concrete construction surface layer; Between heat insulating material and light weight concrete construction surface layer, be provided with band steel.
Consider insulation, load-bearing, the factor such as durable and fire-resistant, described heat insulating material adopts anti-flammability polyphenyl plate or polyurethane sheet.
In order to realize the tight connectivity between steel wire net rack and stress frame, the top and bottom of described steel wire net rack and stress frame composition are cross-linked.
Described band steel is positioned at downside or the upper and lower both sides of Steel Space structure light thermal-insulating integrated board.Band steel plays the effect of support and load.
The beneficial effects of the utility model are: this Steel Space structure light thermal-insulating integrated board is simple in structure, and light weight possesses load-bearing, insulation, heat insulation, sound insulation, the advantage such as fire-resistant, durable simultaneously, and public building energy 65% is become a reality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 stress frame, 2 steel wire net racks, 3 heat insulating materials, 4 light weight concrete construction surface layers, 5 band steels.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This Steel Space structure light thermal-insulating integrated board, comprise two stress frames 1 that opening is relative, it is characterized in that: the steel wire net rack 2 by space truss type between described stress frame 1 connects, fill insulant material 3 between steel wire net rack 2, described heat insulating material 3 adopts anti-flammability polyphenyl plate or polyurethane sheet; The top layer up and down of steel wire net rack 2 is coated with light weight concrete construction surface layer 4; At the downside of Steel Space structure light thermal-insulating integrated board, between heat insulating material 3 and light weight concrete construction surface layer 4, be provided with band steel 5.Described steel wire net rack 2 is cross-linked with the top and bottom of stress frame (1) composition.
This Steel Space structure light thermal-insulating integrated board is take major-minor steel frame, secondary rib as stress frame, be connected into space truss with the steel wire sheet configuring in light weight concrete construction surface layer and the steel wire welded of oblique insertion, the thistle board that anti-flammability polyphenyl plate or polyurethane sheet form is filled out in inside, this plate possesses load-bearing, insulation, heat insulation, sound insulation, the advantage such as fire-resistant, durable, simultaneously simple in structure, light weight, becomes a reality public building energy 65%.
