Description

Insulated wall connector and the prefabricated sandwich heat preserving wall using the connector
Technical field
A kind of insulated wall connector and the prefabricated sandwich heat preserving wall using the connector are the utility model is related to, belongs to building Heat-insulation wall plate applied technical field.
Background technology
At present, heat-preserving wall is the important means for realizing building energy conservation, the assembled green building widelyd popularize in China In, the application of prefabricated sandwich heat preserving wall body is more and more.This heat-preserving wall is that insulation material is positioned over into inside and outside concrete walls Between, inside and outside concrete walls and warming plate are linked into an integrated entity by connector, its combination property is compared to inside heat insulation wall body and outside Heat-preserving wall has more superiority, thus has good development prospect.
Existing prefabricated sandwich heat preserving wall includes outer concrete walls, moderate soak plate and inner concrete wall, and connector is to connect The critical component of inside and outside concrete walls and moderate soak plate is connect, while is resistant to the pass of deadweight interlaminar shear and wind load negative pressure Key member.The gravity load of exterior wall and heat-insulation layer is delivered to interior wall, exterior trim face wall by connector in the form of shearing with moment of flexure Positive and negative blast caused by suffered wind load passes to internal loadbearing wall in the form of pressure and pulling force respectively also by connector, thus It is required that connector will have reliable Anti-pull-press, shear strength and the reliable anchor in concrete in terms of mechanical property first Gu ability;Secondly, sandwich heat preserving wall requirement reaches the insulation purpose of barrier wall inside and outside heat transfer, and this requires connector in heat Work aspect of performance will have less thermal conductivity factor, in order to avoid form " cold bridge " of connection inner-outer wall;In addition, inner-outer wall is by cold and hot meeting Generation difference collapses deformation, thus connector should also have with concrete similar in thermal coefficient of expansion, and to have flexible curved Bent deformability, deformation is collapsed to comply with the difference of coordination external and internal wall;It is longer in view of the design service life of energy saving building, And prefabricated sandwich heat preservation exterior wall requirement is tried one's best and builds the same life-span, this requires connector to possess the endurance quality of brilliance, Itself to be crept in considerable time section smaller, and can be resistant to burn into temperature variation resistant, maintain intensity not to be lowered so that excessively Influence security performance.
The connector being applied at present in prefabricated sandwich heat preserving wall body mainly includes stainless steel adapting piece and fiber It is the class of FRP connectors two to strengthen composite plastic.Wherein, stainless steel adapting piece tension shearing strength is high, heat transfer coefficient is smaller, durable Property it is good, but make it is more complicated, material usage is larger, cost is higher;And the connector heat transfer coefficient of fibre-reinforced plastics it is small, Tensile strength is higher, corrosion resistance is stronger, but shearing strength is low, and long term creep strain performance is not grasped still, so for it is longer when Between the safe bearing load of section have certain risk.
