Described internal lobe concrete panel and siphonal lobe concrete panel use normal concrete or lightweight aggregate concrete to pour and form, configuration reinforcement mesh sheet in internal lobe concrete panel and siphonal lobe concrete panel, described heat-insulation layer is not fire or the warming plate of difficult combustion, according to internal lobe concrete panel and the similarities and differences of siphonal lobe concrete walls plate thickness, put in being divided into and bias two types；
Described reinforcing bar core glass muscle connector is for be wrapped in continuous glass fibre silk impregnation in plain bar or Ribbed Bar, and outer surface continuous glass fibre silk is wound around and ties up, and forms surface and has arcuate relief screw-like muscle core glass muscle；Increase the mechanical snap power with concrete.
Described reinforcing bar core glass muscle connector uses " W " shape, and " W " each flex point spacing is adaptive with described reinforced mesh nodal pitch, reinforcing bar core glass muscle connector at node, is formed sandwich steel reinforcement cage through heat-insulation layer colligation outside of reinforcing bar outside described reinforced mesh.
As preferably, reinforced mesh full node colligation near described reinforcing bar core glass muscle connector.
As preferably, section glue of resinizing in described reinforcing bar core glass muscle connector termination carries out anticorrosion " bridge cut-off " and processes.
5, when Prefabrication employing is put down and crouched folded watering, internal lobe R.C. wall board is first poured, rear installation warming plate and W shape connector, then pour siphonal lobe board concrete.
The beneficial effects of the utility model:
(1) this utility model have employed the new reinforcing steel bar core glass muscle connector as prefabricated concrete sandwich thermal insulation external wall panel, it is strong that this kind of material has bond-anchorage ability, tension, resistance to compression, shearing strength is high, interior outer soft ductility is good, safety stock is high, corrosion resistance is strong, heat conductivity is little, cheap advantage, and concrete, glass fibre, reinforcing bar three's linear expansion coefficient is close, temperature deformation is coordinated, therefore heat-insulating property and the safety durable performance of prefabricated concrete sandwich thermal insulation external wall panel can be effectively improved, solve a difficult problem for universality material selection；(2) stud connector design of the present utility model is " W " shape, can be effectively improved connection anchoring effect, and shearing strength and the integral rigidity of body of wall are greatly improved, and strengthens the integral working of body of wall, solves the technical barrier of connection reliability.
