Detailed description of the invention:
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is described further.
The present invention is as shown in accompanying drawing 1 ~ 9.
A kind of cast-in-situ heat preservation shear wall, post, beam, comprise thermal insulation thermal insulation board 1, reinforcing cage 10, inner side cast-in-situ concrete layer 13, outside cast-in-situ concrete layer or screed 12, as shown in Figure 9.Thermal insulation thermal insulation board 1 has hole 5, have heat insulation 4 in hole 5, there is transverse stiffener 2 thermal insulation thermal insulation board 1 both sides.
Transverse stiffener 2 is established, as shown in Figure 1 in thermal insulation thermal insulation board 1 both sides; Or on the basis of transverse stiffener 2, set up vertical stiffening rib 6, as shown in Figure 2,3.The object that arranges of stiffening rib is to increase the strength and stiffness of thermal insulation thermal insulation board 1.Thermal insulation thermal insulation board 1 is sandwiched in middle part by the stiffening rib of both sides, makes stiffening rib and thermal insulation thermal insulation board 1 form jointly stressed integrated member 1, thus increases thermal insulation thermal insulation board 1 and resist the intensity of side force and the rigidity of resistance to deformation.
Apertured hole 5 on thermal insulation thermal insulation board 1, during concreting, can flow in hole 5, thus concrete in hole, heat insulation 4, reinforcing rib 3 form the larger short column of rigidity.The steel concrete of the short column formed to both sides produces good drawknot effect, and thermal insulation thermal insulation board 1 both sides steel concrete can be acted synergistically, and jointly stressed, the shear wall finally obtained, post, beam have larger intensity and rigidity.
In described heat insulation 4, be interspersed with reinforcing rib 3, layout is blocked at the elongated or middle part of reinforcing rib 3, and wherein, reinforcing rib 3 is reinforcing bar, carbon fiber rod, carbon fiber rope or carbon cloth.The layout object of heat insulation 4 is, the cold bridge existed in partition heat preservation function insulating board 1, optimizes shear wall, post, beam heat insulating effect.Meanwhile, the carbon fibre material that reinforcing rib 3 adopts can bear larger pulling force, and comparatively reinforcing bar coefficient of thermal conductivity is low, uses carbon fibre material better can ensure the heat-insulating property of building.
During the elongated layout of the reinforcing rib 3 in heat insulation 4, reinforcing rib 3 can increase the rigidity of heat insulation 2 greatly, thus thermal insulation thermal insulation board 1 both sides steel concrete is better acted synergistically.Meanwhile, the section form of heat insulation 4 is polygon, circle or oval, and hole 5 shape on the section form of heat insulation 4 and thermal insulation thermal insulation board 1 adapts, and section form is according to concrete engineering application choice.It is straightway or bending segment that elongated reinforcing rib 3 stretches out heat insulation 4 part, and this arranges object and is that the reinforcing rib 3 in heat insulation 4 can reach better anchoring effect with Cast-in-place concrete.
Be interspersed with middle part in heat insulation 4 and cut off reinforcing rib 3, namely when heat insulation 4 two ends anchoring reinforcing rib 3, because the rigidity of heat insulation 4 own is very large, fractureing of reinforcing rib 3 can not affect the drawknot of the reinforcing rib 3 pairs of both sides steel bar concretes be anchored in heat insulation 4.And meanwhile, block in the middle part of reinforcing rib 3 and cause blocking of cold bridge, thus reach better heat preservation and energy conservation effects.The reinforcing rib 3 that middle part is blocked stretches out heat insulation 4 part and is also set to straightway or bending segment.
As also shown in e.g. figs. 4-7.During construction, first prop up side side template 9, place reinforcing cage 10, between the side template 9 installed and reinforcing cage 10, establish cushion block 8, arrange vertical supporting bar 7.Opposite side side template 9 is propped up after fixing thermal insulation thermal insulation board 1 and steel mesh reinforcement 11.
The object arranging cushion block 8 between side template 9 and reinforcing cage 10 is: when 1) building outside layer of concrete or screed 12, the side force pass order that concrete or mortar produce is: thermal insulation thermal insulation board 1-vertical supporting bar 7-reinforcing cage 10-cushion block 8-inner side template 9, namely the side force of outside layer of concrete or screed 12 generation shared jointly by each component, form jointly stressed pattern, reduce the side force that thermal insulation thermal insulation board 1 bears, thus ensure that thermal insulation thermal insulation board 1 is not destroyed.2) setting of cushion block 8, ensure that the distance between reinforcing cage 10 and side template 9, thus makes outermost reinforcing bar have enough protective layer thickness, finally ensure that the construction quality of cast-in-situ heat preservation shear wall, post, beam.Cushion block 8 is made by the hard material that intensity is higher.
Vertical supporting bar 7 is established between reinforcing cage 10 and thermal insulation thermal insulation board 1, vertical supporting bar 7 pairs of thermal insulation thermal insulation boards 1 play location and strengthen the effect of its longitudinal rigidity, do not destroy, to topple and generation level is moved under the side force that thermal insulation thermal insulation board 1 is produced at built layer of concrete or screed 12.Vertical supporting bar 7 section form is circle, ellipse, polygon, H-shaped, and is made by the hard material that intensity is higher.Support bar 7 section form requires to adopt according to concrete Practical Project.
As shown in Figure 8, after each Components installation is in place, build outside concrete or mortar, after outside cast-in-situ concrete layer or screed 12 reach some strength, extract vertical supporting bar 7, build inner side cast-in-situ concrete layer.After inner side cast-in-situ concrete layer 13 and outside cast-in-situ concrete layer or screed 12 reach strength of mould stripping, remove side template 9, finally form integral cast-in-situ heat-preservation shear wall, post, beam, as shown in Figure 9.
