Cast-in-situ wall connector of the present invention, adopts Shooting Technique one-shot forming; Its manufacturing process is, the first step, by pultrusion molding process, first produces reinforcing rib, and reinforcing rib of the present invention adopts FRP base material of the prior art to make; Second step, the mould of making cast-in-situ wall connector; The 3rd step, puts into mould single injection-molded by reinforcing rib, forms cast-in-situ wall connector.
Pultrusion molding process of the present invention is technique of the prior art, and its concrete processing step the present invention is not described in detail.
Cast-in-situ wall connector of the present invention, when use, cast-in-situ wall connector is inserted in wall insulating layer, in heat-preserving wall part in cast-in-situ wall connector, outer panel, middle plate and interior plate all insert, are fixed in insulation layer, fixing steel bar layer in cruciform reinforcement mounting groove in wall part outside, and insert plate in reinforcing bar holddown groove, fix steel bar layer; Interior wall Substrate sheet and exterior wall Substrate sheet are installed, and interior wall Substrate sheet contacts with the termination of inner wall part, and exterior wall Substrate sheet contacts with the termination of exterior wall part; Concreting between interior wall Substrate sheet and insulation layer, outside concreting between plinth course steel plate and insulation layer; The external surface of the other end of inner wall part of the present invention is arranged with two dovetail grooves, its Main Function makes in the time of concreting, concrete is poured on connector body and reinforcing rib simultaneously, so effectively prevents that rocking of body of wall from can break connector body.Be that reinforcing rib has been born main load-bearing effect (shear-stable effect), drawing effect, the effect of exterior wall in connecting.So be just called cast-in-situ wall connector.
The present invention also comprises plate, and described plate is fixed in reinforcing bar holddown groove.Plate Main Function of the present invention is fixing steel bar layer.
The preparation method who the invention also discloses a kind of cast-in-situ wall connector, comprises the steps:
1) produce reinforcing rib;
2) mould of making cast-in-situ wall connector;
3) reinforcing rib is put into the mould described in step 2;
4) adopt Shooting Technique to carry out single injection-molded to mould in step 3, form cast-in-situ wall connector.
The material of reinforcing rib of the present invention is FRP.FRP base material of the present invention is base material of the prior art, and its concrete composition the present invention is not described in detail.
Shooting Technique of the present invention is Shooting Technique of the prior art, and its concrete technology step is existing processing step, and its concrete steps the present invention do not elaborate.
The present invention's advantage compared with prior art: the feature of having utilized the FRP base material of prior art, in conjunction with existing traditional construction process pattern, to need prefabricate building unit, in the case of traditional construction process pattern is constant, do not need prefabrication, solved like this prefabricated units long-distance transports problem, the high and Around Buildings of cost of transportation need to have the problems such as corresponding prefabricated factory, has also solved building energy conservation heat insulation problem simultaneously.New material, the achievement that new technology perfect adaptation is applied in building field.It is poor that first this cast-in-situ wall connector of the present invention will conduct heat, heat insulation good, is secondly the effect that will possess reinforcing bar, there is good tensile strength, flexural strength, shear strength, secondly be again under cement weakly alkaline environment, have good durability, stability.On reinforcing rib, respectively driving two dovetail grooves at two ends is to have very important effect, is also the key of this cast-in-situ wall connector success.
