Description
Technical field
The present invention relates to the Formwork Installation Method of a kind of architectural engineering, particularly reserve the Formwork Installation Method of post-cast strip.
Background technology
In recent years, along with the fast development of China's economy, skyscraper is on the increase, and post-cast strip is high-building construction
Important component part.Arranging post-cast strip and can efficiently reduce the generation of distress in concrete, the contraction of differentiation large area concrete should
Power, thus effectively solve the problems such as flexible, the sedimentation of skyscraper.
At present, the method for obligating of basement wall of high-rising buildings post-cast strip generally uses the method for metal binding wire net, but should
There is a lot of drawback in method: one is fixing insecure, and along with the increase of concreting height, lateral pressure increases, and steel wire goes out
Existing obscission；Two is that steel plate for sealing water position easily offsets；Three is bad sealing, is mainly reflected in concrete in steel wire mesh
Flow out, steel wire and concrete bonding form rough interface after solidification, affect outward appearance, cut that workload is big, affect
Construction speed.
The most known basement wall is reserved the method to set up of post-cast strip and be there is above-mentioned all inconvenience and problem.
Summary of the invention
The technical problem to be solved in the present invention is to provide the Formwork Installation Method of a kind of reserved post-cast strip, can go by template
Substitute steel wire, it is ensured that tight-closed and fixation, and steel plate for sealing water can be fixed make it not offset.
In order to solve above-mentioned technical problem, the invention provides the Formwork Installation Method of a kind of reserved post-cast strip, it includes
Following steps:
