Abstract

The utility model discloses a kind of preformed self thermal insulation composite sandwich reinforced concrete laminated floor slab, it is made up of bottom plate 1, side floor 2, middle floor 3 and light thermal-insulation batten 4, and light thermal-insulation batten 4 is clipped among the cavity that bottom plate 1, side floor 2 and middle floor 3 are surrounded;The section of side floor 2 is inverted L shape, and the section of middle floor 3 is T-shaped, is connected as one between its top provided with lateral connection reinforcing bar 5 in order to pour overlapping layers with after.Because the utility model uses cavity box-structure, bearing capacity is strong, big using span, meanwhile, heat-insulation layer is disposed with casing realizes the integration of structure and building energy conservation, so as to have from heavy and light, structural behaviour is good, and span is big, good effect of heat insulation, the advantage of low cost.

Description

A kind of preformed self thermal insulation composite sandwich reinforced concrete laminated floor slab
Technical field:
The utility model is related to a kind of floor, more particularly to a kind of preformed self thermal insulation composite sandwich reinforced concrete laminated floor slab.
Background technology:
Being pushed further into and improving with building energy conservation, the insulation of construction floor has turned into building enclosure and has built section One of controlling indicator of energy.Therefore, as the energy-saving building technology of wall, to save being constructed into for flooring insulation This, researches and develops new self-heat conserving floor, with wide market prospects and good economic and social benefits.
Utility model content:
The purpose of this utility model is to provide that a kind of thermal and insulating performance is good and the reliable preformed self thermal insulation of intensity is compound Sandwich laminated floor slab.
The utility model provide a kind of preformed self thermal insulation composite sandwich reinforced concrete laminated floor slab, it by bottom plate, side floor, Middle floor and light thermal-insulation batten composition, light thermal-insulation batten is clipped among the cavity that bottom plate, side floor and middle floor are surrounded.
Preferably, the section of the side floor is inverted L shape, the section of middle floor is T-shaped, provided with laterally between its top Connection reinforcing bar connects as one in order to pour overlapping layers with after.
Preferably, outside of the longitudinal both sides of the bottom plate along side floor is stretched out to form longitudinal edge of a wing.
In order to reduce heat bridge influence, the bottom plate is prestressed reinforced concrete plate, and the side floor and middle floor are unit weight Less than 1500kg/m3, thermal conductivity factor is less than 0.7W/ (mk), lightweight aggregate structural thermal insulation concrete of the intensity more than 10Mpa.
In order to further improve heat insulating effect, the material that the light thermal-insulation batten is used is less than 20kg/ for unit weight m3, light heat-insulating material of the thermal conductivity factor less than 0.05W/ (mk).
Because the utility model uses cavity box-structure, bearing capacity is strong, big using span, meanwhile, it is disposed with casing Heat-insulation layer realizes the integration of structure and building energy conservation, so that with from heavy and light, structural behaviour is good, span is big, insulation Effect is good, the advantage of low cost.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Embodiment
As shown in figure 1, this preformed self thermal insulation composite sandwich laminated floor slab that the present embodiment is provided, it is by bottom plate 1, side rib Plate 2, middle floor 3 and light thermal-insulation batten 4 are constituted, and light thermal-insulation batten 4 is clipped in what bottom plate 1, side floor 2 and middle floor 3 were surrounded Among cavity, the outside of longitudinal both sides of bottom plate 1 along side floor 2 is stretched out to form longitudinal edge of a wing, and the section of side floor 2 is inverted L shape, The section of middle floor 3 is T-shaped, connects as one, has in order to pour overlapping layers with after provided with lateral connection reinforcing bar 5 between its top Have from heavy and light, structural behaviour is good, span is big, good effect of heat insulation, the advantage of low cost, to realize structure and building energy conservation one Body.Bottom plate 1 is set to prestressed reinforced concrete plate, side floor 2 and middle floor 3 are set to unit weight less than 1500kg/m3, heat conduction system Number is less than 0.7W/ (mk), and intensity is more than 10Mpa lightweight aggregate structural thermal insulation concrete, to reduce heat bridge influence, it is ensured that heat-insulated Performance.It is that unit weight is less than 20kg/m by the material selection of light thermal-insulation batten 43, thermal conductivity factor be less than 0.05W/ (mk) it is light Matter heat-insulating material, further to improve the effect of insulation.
When manufacturing, first the good bottom deformed bar of tensioning on special production platform, then sets prefabricated sandwich The mould of floor, first pours the concrete of bottom plate, then lays light thermal-insulation batten and lateral connection reinforcing bar, then pours light thermal-insulation Concrete floor, is most conserved through the demoulding afterwards.
During construction, first the prefabricated composite sandwich floor described in several piece is supported on beam (or wall), its reserved longitudinal direction The edge of a wing is formed the template of longitudinal girt strip, and prefabricated board then is poured into overlapping layers with after by rear pouring concrete girt strip and surface layer is superimposed on The self-heat conserving composite sandwich reinforced concrete laminated floor slab of assembled integral is formed together.
