Description
Technical field
The present invention relates to the civil engineering construction technical field, relate in particular to the template system of both sides, a kind of shrinkage joint shear wall.
Background technology
The building shrinkage joint is also referred to as the shrinkage joint, refers in order to prevent building member because climate temperature changes (heat rises, shrinkage), makes fabric structure produce crack or destruction and a build joint vertically arranging along the suitable position of house length direction.
The both sides at shrinkage joint respectively have shear wall one, when constructing at the scene, because the inner space at shrinkage joint is narrow and small, wall form is not easy to reinforce, at present general employing is first completed the concreting of shrinkage joint one side and is carried out the construction of opposite side structure afterwards again, and its constructure scheme mainly contains following several:
Scheme one: according to traditional mold method, complete the construction of the concrete shear wall structure of shrinkage joint one side, then polyphenyl plate 04 is set and lays bakelite plate as disposable packing material on its surface in the shrinkage joint of the shear wall 01 of completing a construction side, perhaps adopt old wood glue plate to add rough ground 044 as disposable packing material, then carry out the casting of shrinkage joint opposite side concrete shear force wall by the single surface formwork system that is consisted of by template 02 and falsework 03, as shown in Fig. 1 and Fig. 2;
Scheme two: complete the concrete shear wall structure construction of shrinkage joint one side according to traditional mold method, the shear wall of opposite side adopts square steel 003 or other shaped steel as the vertical and horizontal keel, wood glue plate 001 is as template, adopt unidirectional fastening screw 002, form the split bolt reinforcement system but tighten from operation one side penetrates into the nut of no operatton face one side firm welding, as shown in Figure 3.
can find out in the constructure scheme of the shear wall of the both sides, shrinkage joint that provide in scheme one and scheme two, the shear wall of the both sides at shrinkage joint be all by first to the shear wall of shrinkage joint one side complete build after, by the mode of single surface formwork, the shear wall of the other side in shrinkage joint is built again, the reinforcing difficulty of single surface formwork system is larger, and what this kind mode also needed to grow builds the time, can't guarantee the duration in the situation that the construction period requirement is tighter, included disposable packing material in shrinkage joint in scheme one, the benzene plate is combustible material, can't satisfy fire protection requirement, be the rigidity packing material and old wood glue plate adds rough ground, with it during as the packing material at shrinkage joint, can affect the structure function of deformation joint.
Therefore, how can provide a kind of speed of application faster both sides, shrinkage joint shear wall formwork system be the technical problem that present those skilled in the art need solution badly.
Summary of the invention
