Description
Technical field
The present invention is the improvement to prefabricated concrete self-insulating shear wall and assembling concrete building shear wall structure; Relate in particular to and a kind ofly can effectively cut off cold and hot bridge; Wall heat transfer coefficient is lower, and the anchor connector cost is low, assembles simpler; And can omit a large amount of supplemental support, can realize the prefabricated concrete self-insulating shear wall and the assembly structure of assembling fast.
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 scene formwork erection pour concrete successively, applies outer insulation.For example Chinese patent CN101289883, CN101089306, CN202202518, CN202214844, CN200952198, CN202081536, CN201722816 etc. are said.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 with in-situ concrete wall is compound forms by one side, the at interval embedding steel member connection of compound employing.It only is that part realizes factory prefabricating, and also need arriving cast-in-site, to coagulate the cob wall body superimposed, thereby do not realize the prefabricated fully of shear wall; Secondly, composite monolithic connects, and adopts the steel member of high heat conduction, thereby has cold and hot bridge, influences 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 range upon range of closing; The tyre architectural surface, the completion that is prefabricated in the factory, three layers through being welded with the steel mesh reinforcement connection of tension rib.The same thickness direction adopts simple reinforcing bar drawknot to have cold and hot bridge.
Above-mentioned prefabricated shear wall adopts three layer construction; The centre is provided with isolation layer, is connected but still adopt the heat conductor reinforcing bar to draw between outer concrete Ye Qiang and interior concrete shear wall, and 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 cold and hot bridge phenomenon,, thereby limited the further reduction of self-heat preservation heat insulation wall thermal transmittance if exist cold and hot bridge that heat transfer property is increased substantially.
Chinese patent CN201687102 assembled integral shear wall structure system, the aforementioned three layer construction of the same employing of prefabricated concrete self-insulating shear wall, its improvement is to make three interlayer spot distribution anchor connectors, adopts FRP plate, FRP joint bar and plastic sheath ring connector.More above-mentioned prior art owing to adopt the FRP connector of low heat conduction, thereby can effectively reduce or eliminates cold and hot bridge, makes the self heat insulation wall heat-proof quality improve major step.But the FRP connector, self cost is high far beyond reinforcing bar, and especially the tensile property of FRP material own is better; But resistance to compression and shear behavior are relatively poor relatively; Therefore for satisfying building required resistance to compression of combined wall and shear behavior, the connector cross section is relatively large, has increased the cost of connector especially; 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.
Secondly, monoblock wallboard splicing structure (plate-plate assembly unit) is adopted in existing prefabricated concrete shear wall assembling (CN201687102), and assembling is stretched out body of wall transverse structure reinforcing bar anchoring overlap joint by the side about the wall body, and formwork erection cast ater-casting concrete connects into integral body; Body of wall assembly unit up and down; It is the reinforced bar sleeve of pre-buried and connection identical with body of wall longitudinal screw main reinforcement quantity in prefabricated concrete wall bottom; During assembling the prefabricated concrete shear wall in upper strata is sling, made pre-buried each reinforced bar sleeve in bottom be inserted in the main reinforcement that stretch out lower floor prefabricated concrete wall upper end, use interim support fixation body of wall again; Through to the slip casting one by one of each reinforced bar sleeve, make lower floor body of wall upper end stretch out main reinforcement fixed in the body of wall bottom sleeves of upper strata (forming embedded bar sleeve+slip casting connects).The main deficiency of this assembly structure has three: one, because shear wall is that solid concrete wall weight is bigger, full piece assembly unit requires high to the hanging device hoisting weight, need large-scale hoisting machinery; The 2nd, site assembly bothers and is difficult to accomplish quick; For example lift by crane the prefabricated concrete shear wall in upper strata, need hole, a hole and lower floor's concrete shear wall to stretch out the reinforcing bar contraposition and insert, consuming time more; And it is fixing also to need more supplemental support to help after the body of wall lifting puts in place, causes the supplemental support large usage quantity; The 3rd, lower floor's body of wall reinforcing bar is connected with upper strata body of wall sleeve slip casting; Sleeve slip casting connects, and not only length sleeve is longer, has also increased the body of wall cost; And slip casting workload one by one is big; And the slip casting quality of connection influenced by manual operation bigger, slip casting is unreal to be prone to cause jointing intensity to reduce, thereby quality of connection is difficult to reliably guaranteed.Particularly full piece assembly unit can not realize the quick assembling of assembled architecture, can lose assembled architecture part advantage, also makes assembly cost improve.
The building scale of construction is big, and is low-cost very important, and therefore above-mentioned prior art deficiency still has is worth improved place.
Summary of the invention
