Method for pouring reinforced concrete structure provided with deformation joint and deformation joint steel fly die template

Abstract

The invention discloses a method for pouring a reinforced concrete structure provided with a deformation joint and a deformation joint steel fly die template. Opposite-pull holes penetrating a channel steel back edge and a steel fly die are formed on the back of the deformation joint steel fly die template and welded with nuts, and nut holes are superposed with the opposite-pull holes to form threaded through holes; and an opposite-pull screw of which one end is a threaded head and the other end is a hexagon is machined, and a threaded part is formed at the joint of the hexagon and an opposite-pull screw main body part. During construction, each opposite-pull screw is wrapped with a polyvinyl chloride (PVC) sleeve manually and then penetrates through a concrete template bin, the threaded head of each opposite-pull screw is aligned with the corresponding threaded through hole of the steel fly die, the hexagon is clamped from the hexagonal end by using a spanner, the threaded head of each opposite-pull screw is screwed into the threaded through hole and clamped, and the threaded part at each hexagonal end is tightened and reinforced by using a fastening nut. For facilitating construction and hoisting transfer of a template system, U-shaped hoisting rings and climbing through holes are arranged on the steel fly die.

Description

technical field [0001] The invention relates to a pouring method for a reinforced concrete structure and a deformation joint steel flying formwork, belonging to the technical field of construction engineering. Background technique [0002] Deformation joints are vertical joints set at appropriate parts of the building to prevent expansion and contraction deformation of building components due to changes in temperature and humidity. The width of the deformation joint is usually about 10cm, so the space for reinforced concrete pouring construction at the position of the deformation joint, especially the space for the formwork erection is very narrow, so the pouring method of the reinforced concrete structure with deformation joints has always been a problem that needs to be solved in the pouring construction A big problem. The conventional construction method is to use ordinary 18mm formwork to erect the formwork warehouse, use wooden squares as internal supports between the ...

AI Technical Summary

Problems solved by technology

This method and the formwork system need to be strengthened together from the outside of the two concrete formwork warehouses on both sides of the deformation joint, and cannot be operated from one side, so there must be a certain space outside the two warehouses of the concrete formwork warehouse on both sides of the deformation joint.

In actual construction, many building structures have more than one deformation joint, but several or even tens of hundreds of continuous arrangements, so in many cases, only one side of the concrete warehouse can be operated (the other side is also a 10cm wide deformation joint. ), at the same time, since the tension bolts must completely pass between the two concrete formwork warehouses, if the distance between the front and rear of each concrete formwork warehouse is relatively long, then longer tension bolts must be used, which is not easy for the tension bolts At the same time, the reliability of bolts is difficult to guarantee, and the installation of steel pipe supports also makes the construction process too cumbersome and inconvenient for actual operation

[0004] Therefore, the above-mentioned concrete structure pouring method and deformation joint formwork structure provided with deformation joints are not ideal.
