technical field

The invention relates to the field of building construction, and relates to a chisel-free formwork support structure for concrete pouring construction and a construction method thereof.

Background technique

Chiseling is a kind of rough structure such as chiseling out dents on the completed concrete structure surface, which is a conventional measure for the firm and stable combination of new and old concrete. The existing chiseling methods are usually tool chiseling, that is, using special chiseling tools to excavate the surface of the formed concrete structure. This method is not only labor-intensive, time-consuming and labor-intensive, but also not efficient, and it is easy to damage the concrete. The main body of the structure causes damage and destruction. In order to solve this technical problem, the prior art discloses a non-chiseled wool stop belt, which usually adopts a new type of composite fiber material, has good wear resistance and tensile resistance, and has a pockmarked surface; Fix the non-chiseling grout stop belt on the surface of the formwork. After the concrete is poured, tear off the no-chisel grout stop belt to form a chisel structure on the surface of the concrete structure, which not only saves time and effort, but also has high efficiency and The structure is stable, and the combination of old and new concrete is firm. However, in the existing construction process, the formwork is usually spliced with wooden formwork, and the construction and laying of the formwork itself is time-consuming and laborious, and manual binding or nailing is required between the chisel-free wool stop belt and the formwork. The workload of the wool stop belt is still not small, the construction intensity is relatively high, the overall efficiency is not high, and because of the manual laying, the formwork is uneven, and the binding and nailing are not easy to control, which may easily lead to no chiseling. The overall laying of the belt is not smooth, and there are many folds, which affect the shaping of the rough surface. For this reason, the chisel-free construction of existing concrete structures needs to be improved.
