Construction method of combined fixed integral lifting elevator shaft shaped operation platform

Abstract

The invention relates to a construction method for combined type fixed and integral lifting of an elevator shaft stereotyped operation platform. The platform consists of bearing diagonal rods, limit gear rods, horizontal joists, operation-platform vertical rods, transverse horizontal rods, longitudinal horizontal rods, square wood blocks, wood glue boards, steel pipes and high-strength bolts, wherein one end of each bearing diagonal rod is supported on a shear wall in an angle of 45 degrees, and the other end of the bearing diagonal rod is supported on a floor at the exit of an elevator compartment; the limit gear rods and the horizontal joists are arranged between the bearing diagonal rods; the operation-platform vertical rods are mounted on the bearing diagonal rods; the transverse horizontal rods and the longitudinal horizontal rods are in combined connection and fixed together with the operation-platform vertical rods; wood glue boards are laid on the corresponding transverse horizontal rods and longitudinal horizontal rods; each steel pipe penetrates through shear-wall reserved holes and is inserted in the corresponding transverse horizontal rod, and the steel pipe and the transverse horizontal rod are fixed together. The construction method mainly comprises the following steps: setting up the bottom bearing diagonal rods; mounting the limit gear rods; mounting the horizontal joists, setting up the operation-platform vertical rods; setting up a lower operation platform; setting up an upper operation platform; and overall lifting the operation platform and the like.

Description

technical field [0001] The present invention relates to a construction method for a combined and fixed integrally hoisted elevator shaft stereotyped operating platform, in particular to a construction method for a reserved hole in a shear wall, an expandable operating platform, and an integrally hoisted elevator shaft stereotyped operating platform, especially It is suitable for the construction of closed elevator shafts in super high-rise buildings. Background technique [0002] In recent years, with the rapid development of high-rise buildings in China, the elevator shafts in high-rise buildings are generally cast-in-place reinforced concrete cylinder structures. In the construction of the elevator shaft structure, the support and removal of the inner mold is a difficult point. Full-height inner scaffolding needs to be erected from bottom to top. The site in the well is narrow, and when loose steel (wooden) forms are used, it is very laborious to dismantle them. Especia...

AI Technical Summary

Problems solved by technology

The site in the well is narrow, and when loose steel (wooden) forms are used, it is very laborious to dismantle them

Especially when removing the formwork, because the inner formwork is squeezed tightly by the side pressure of the concrete, it is particularly difficult to remove, which often causes deformation and damage of the formwork

[0003] At present, the construction operation platform of the shear wall formwork in the elevator shaft of high-rise buildings generally adopts floor-mounted steel pipe fastener scaffolding. Inspection and acceptance, inconvenient cleaning of construction waste in the well, long-term backlog of a large number of rental equipment and many other disadvantages

On the other hand, during the lifting process of the operation platform, the load-bearing slanting rod and the limit device at the lower part of the operation platform need to be removed, the stability of the operation platform needs to be considered, and the support of the formwork inside the shear wall is also difficult
