Description
Technical field
This utility model relates to assembled architecture outer wall body technique field, especially relates to a kind of outside precast concrete
The connector of wallboard.
Background technology
Precast concrete external wall panel mixes for being processed into the reinforcement for building assembling in precast plant (field) or construction site
Concrete board type component, is called for short wallboard or wallboard.Use precast concrete wall panel to build assembled large panel building, factory can be improved
Change, mechanized construction degree, reduce situ wet operation, saves on-the-spot recruitment, overcomes seasonal effect, shortens the construction cycle.
At present, precast concrete external wall panel includes facade plate, gable board and eaves wallboard three kinds；Facade plate is certainly
Load-bearing wall panel, gable board and eaves wallboard are load-bearing wall panel.Side fascia except should have sound insulation with fireproof function in addition to, also should have every
Effects such as heat insulation, impervious, freeze thawing resistance, anti-carbonization and meet the requirement of art of architecture decoration, Side fascia can be single with light-weight aggregate
Material is made, it is possible to use composite (structure sheaf, heat insulation layer and finish coat) to make.
At present, mostly the production technology of precast concrete external wall panel is: be processed prefabricated mixed in the mould made
Solidifying cob wall plate, can be divided into cleaning template, separant coating, Mo Neibu muscle, concreting, vibration moulding, maintenance, form removal, inspection,
The operations such as finished product stacking and transport.Its method has produced by plane moulding and formwork erection to produce two kinds.It is divided into pedestal method, flat-die by production technology
Unit flowing water method, flat-die transmit flowing water method and battery mould or paired formwork erection method four kinds.
Precast concrete external wall panel structure, because it has steady quality, short construction period, spy that heat-insulating, fire-preventing performance is good
Property, more and more it is applied in actual construction.
The most common precast concrete external wall panel mostly is sandwich heat preservation Side fascia, and connector therein needs to run through insulation
Material layer, is anchored in adiabator layer on inside and outside two-layer xoncrete structure, reaches to strengthen insulation material strong with concrete bonding
The purpose of degree.
The insulation material of prefabricated vacuum heat-insulating plate thermal insulation external wall panel is vacuum heat-insulating plate, and it is by evacuation encapsulation technology
The ultrathin warming plate made, heat-insulating property is strong；But vacuum heat-insulating plate is in use forbidden to be pierced, otherwise heat-insulating property
Can seriously reduce.If be placed between vacuum heat-insulating plate by anchoring piece, gap mistake between vacuum heat-insulating plate can be caused because of anchoring piece
Greatly, because heat bridge effect is serious, the integral heat insulation performance of precast concrete external wall panel can seriously be reduced.
Therefore, how to provide a kind of strong connector for precast concrete external wall panel so that it is reducing as far as possible
In the case of heat bridge, moreover it is possible to vacuum heat-insulating plate is carried out effective anchorage support, and and inside and outside both concrete layers between more
Good connection is that those skilled in the art need badly and solve the technical problem that.
Utility model content
The purpose of this utility model is to provide a kind of connector for precast concrete external wall panel, and this connector can
In the case of as far as possible reducing heat bridge, moreover it is possible to vacuum heat-insulating plate is carried out effective anchorage support, and with inside and outside two-layer coagulation
Preferably connect between soil layer.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is:
A kind of connector for precast concrete external wall panel, described precast concrete external wall panel includes xoncrete structure
Layer, heat-insulation layer and connector, described heat-insulation layer is spliced by polylith warming plate, and described connector includes for being arranged at
