Description
Technical field
Utility model is the improvement to Prefabricated Concrete self-heat conserving shear wall and assembling concrete building shear wall structure, relate in particular to and a kind ofly can effectively cut off cold-heat bridge, wall heat transfer coefficient is lower, the anchor connector cost is low, assemble simpler, and can omit a large amount of supplemental support, can realize Prefabricated Concrete self-heat conserving shear wall and the assembly structure of fast assembling.
Background technology
Shear wall can bear vertical and horizontal loading, can load-bearing go along with sb. to guard him again, and continuous from top to bottom, usually for the bulk strength building of having relatively high expectations, employing shear wall structure.Existing shear wall concrete building mostly adopts successively formwork erection pour concrete of scene, applies outer insulation.Described such as Chinese patent CN101289883, CN101089306, CN202202518, CN202214844, CN200952198, CN202081536, CN201722816 etc.Along with the technological progress of building industry, assembled architecture rises gradually.Shear wall also has employing prefabricated, site assembly.
Chinese patent CN1888343 composite heat insulation concrete shear wall is covered with the prefabricated thermal insulation concrete wall of adiabator layer and in-situ concrete wall is compound forms by one side, and Combined Mining connects with the embedding steel member in interval.It only is that part realizes factory prefabricating, and it is superimposed also need to arrive the solidifying cob wall body of cast-in-site, thereby does not realize the fully prefabricated of shear wall; Secondly, composite monolithic connects, and adopts the steel member of high heat conduction, thereby has cold-heat bridge, affects the further reduction of self heat insulation wall coefficient of thermal conductivity.
Chinese patent CN201217855 one-shot forming band heat insulation facing precast concrete short-limb shear wall provided, by shear wall, insulation layer, mortar bonding layer three stacked closing, architectural surface is prefabricated in the factory and finishes in addition, and three layers by being welded with the steel mesh reinforcement connection of tension rib.The same thickness direction adopts simple reinforcing bar drawknot to have cold-heat bridge.
Above-mentioned precast shear wall adopts three layer construction, the centre arranges isolation layer, but still adopting the heat conductor reinforcing bar to draw between outer concrete Ye Qiang and interior concrete shear wall is connected, connecting reinforcement unavoidably will produce heat bridge (thermal bridges) or cold bridge (cold bridges), and the self heat insulation wall heat transfer property, largely be decided by the cold-heat bridge phenomenon, if exist cold-heat bridge that heat transfer property is increased substantially, thereby limited the further reduction of self-heat preservation heat insulation wall thermal transmittance.
Chinese patent CN201687102 assembled integral shear wall structure system, the aforementioned three layer construction of the same employing of Prefabricated Concrete self-heat conserving shear wall, its improvement is to make three interlayer spot distribution anchor connectors, adopts FRP plate, FRP joint bar and Plastibell connector.More above-mentioned prior art owing to adopt the FRP connector of low heat conduction, thereby can effectively reduce or eliminates cold-heat bridge, makes self heat insulation wall heat-proof quality raising major step.But the FRP connector, cost taken by themselves is high far beyond reinforcing bar, and especially the tensile property of FRP material own is better, but resistance to compression is relative with shear behavior relatively poor, therefore for satisfying the required resistance to compression of building composite wall and shear behavior, the connector cross section is relatively large, has increased especially the cost of connector; Secondly, the FRP connector is made relative complex, also is the another reason that causes the connector cost up.For using in a large number in the body of wall, architectural being difficult to of high cost accepted, thereby can limit it and apply.
