Description
Technical Field
The invention belongs to the technical field of building construction equipment and methods, and relates to a template for placing embedded steel bars and a construction method thereof.
Background
The large-scale structures often need to be poured by stages by concrete, and the first-stage concrete and the second-stage concrete are better combined or installation of equipment embedded parts is facilitated by embedding reinforcing steel bars in the first-stage concrete during implementation, for example, floating bollard grooves of ship lock engineering are usually provided with the second-stage concrete due to complex structures.
The traditional method for pre-embedding the reinforcing steel bars is to make the end parts of the reinforcing steel bars penetrate out of the arranged holes by forming the holes in the template. However, this method has the following disadvantages:
firstly, the quality effect is poor, and the holes on the template are too many, which can cause the loss of concrete grout and cause local concrete defects; secondly, the construction potential safety hazard is large, the structure of the template can be influenced by too many holes on the template, the rigidity of the template is reduced, and in addition, the embedded steel bars can clamp the template, so that the template is difficult to remove, and a great potential safety hazard is formed; thirdly, construction cost is relatively high, because the size and the position of the embedded steel bars are changed, the template is probably to be transformed, investment of template cost is increased, construction progress lag can be caused due to difficulty in template dismantling, and corresponding cost can be increased due to phase change.
