Post-closed outer wall post-cast strip reinforcement construction method

Abstract

The invention discloses a post-closed outer wall post-cast strip reinforcement construction method. The method comprises the following steps that a concrete precast block mold is designed according tothe size of a concrete precast block, and the concrete precast block mold is built and installed according to design and construction specification requirements; and transverse steel bars and longitudinal steel bars are laid in the concrete precast block mold, then a plurality of connecting nuts are pre-buried in one end of the concrete precast block mold, reinforcing steel bars are laid on the two sides of the connecting nuts, the reinforcing steel bars and the transverse steel bars are bound and connected, then the connecting nuts and the reinforcing steel bars are welded and fixed, and lifting rings are pre-buried in the two sides of the concrete precast block mold. According to the construction method, the construction cost is reduced, the consumption of turnover materials is reduced,the post-cast strip is safely and reliably closed in advance, the construction progress is accelerated, energy conservation and environmental protection are achieved, meanwhile, the construction process is simple in manufacturing, flexible in operation and high in efficiency, the cost is reduced, the efficiency is improved, and then the technical problem that time and labor are wasted during reinforcement pouring after the post-cast strip is closed in advance is solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and relates to a construction method for reinforcing a post-casting belt of a rear-closed outer wall. Background technique [0002] The post-pouring belt is a temporary construction joint set in the building. The joint is reserved for a period of time before pouring, that is, the original "extra long" plane is "divided into parts" so that it can be completed in a short period of time The shrinkage of concrete, the release of restraint stress such as deformation caused by excessive vertical load difference. After the construction of the post-cast belt is completed, the structure will be "turned into a whole", which greatly reduces the influence of the above stress on the structure and reduces the excessive setting of permanent deformation joints. This kind of "seam" not only solves the differential settlement between buildings, but also solves the shrinkage deformation of concrete a...

Problems solved by technology

Since the construction of the post-pouring belt involves secondary operations, it not only actually increases the complexity of the construction process, but also affects the construction progress and increases the construction cost.

Therefore, there is an urgent need for an efficient and economical technical solution to solve the time-consuming and labor-intensive technical problems of consolidating and pouring such post-casting belts after they are closed in advance.
