Installation and construction method of high formwork of super high-rise elevator shaft

Abstract

The invention discloses an installation and construction method of a high formwork of a super high-rise elevator shaft. The installation and construction method comprises two stages including a construction preparation stage and a construction operation procedure, wherein the construction operation procedure comprises the steps of (1) processing the formwork, (2) installing and fixing a bottom die, (3) installing an inner support frame, (4) installing and fixing a side die, (5) integrally reinforcing, (6) hoisting a box body in place, (7) installing a connecting reinforcement, (8) pouring concrete, and monitoring, and (9) removing the formwork. According to the reinforcement and construction method of the high formwork of the super high-rise elevator shaft, traditional formworks, battens and steel pipes are used as raw materials, the formworks are used as face plates, the battens are used as inner ridges, the steel pipes are used as outer ridges so as to manufacture the box body, a lifting machine is installed in the elevator shaft, steel pipe supports are arranged in the box body so as to solve the problem of side pressure of concrete to the box body, the box body is locked by adopting the steel pipes so as to solve the problem of floating resistance of the box body to the concrete, and the steel pipes are connected with bottom reinforcements of a raft by utilizing round steel.

Description

technical field [0001] The present invention is designed in the field of building construction, and is specifically a construction method applicable to the installation of well pit formwork in equipment foundations such as elevator shafts, sumps, large venues, and industrial workshops in super high-rise rafts. Background technique [0002] With the development of society, especially the continuous acceleration of urbanization, the large flow of population has caused a large number of people to gather in some cities with relatively concentrated social resources, which makes it necessary to accommodate more people and other social resources on a limited land area. The land is very tense. Therefore, the development of high-rise buildings and underground buildings has become a method to solve the maximum utilization rate of limited land. [0003] With the development of super high-rise building technology, the building height has been refreshed by new records again and again. I...

Problems solved by technology

[0005] Usually, for similar well pits that are relatively deep, in order to prevent the formwork system from being unstable against the side, screw rods are embedded on the steel skeleton for connection, and internal braces are used for reinforcement; in order to prevent the formwork from floating, usually on the formwork system Take the form of stacking, such as stacking formwork, steel bars and other counterweights, the construction time is long and the construction process is complicated

[0006] Therefore, in order to solve the inconvenience and quality defects caused by the usual practice of pit formwork reinforcement systems such as elevator shafts, it is already a problem worth studying to provide a new construction method for super high-rise elevator shaft high formwork reinforcement
