Description

An elevator shaft construction and protection platform

technical field

The utility model relates to the technical field of construction engineering, in particular to an elevator shaft construction and protection platform.

Background technique

Generally, with the improvement of the degree of urbanization in our country, there are more and more high-rise buildings, and elevators are an important part of high-rise buildings. The elevator shaft inside the high-rise building has a high risk factor due to the vertical connection. When the construction personnel carry out related construction work such as wall reinforcement binding, formwork construction, concrete pouring, and formwork removal, they must set up a safe operation platform to facilitate construction. The traditional elevator shaft operating platform is built from the bottom up by the steel pipe scaffolding. It is time-consuming and laborious to build and dismantle, which makes the construction process of the traditional elevator shaft operating platform cumbersome and complicated. In recent years, a special elevator shaft construction platform has also appeared. The whole is welded by section steel, the overall size is large, the versatility between different projects is poor, and it does not have the horizontal protection function to prevent objects from falling.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art and provide an elevator shaft construction and protection platform.

The technical scheme of the utility model is realized in the following manner. The structure of the elevator well construction and protection platform includes a load-bearing beam and a load-bearing platform,

There is a load-bearing beam at the door opening of the elevator shaft, and a reserved square hole is opened on the shear wall of the elevator shaft opposite to the door opening of the elevator shaft, and one end of the load-bearing beam is plugged into the reserved square hole on the shear wall Inside, the other end of the load-bearing beam is fixed at the door opening of the elevator shaft, and the load-bearing beam is set horizontally;

A load-bearing platform is arranged horizontally above the load-bearing beam.

The edge of the load-bearing platform is set on the inner periphery of the inner wall of the elevator shaft, and the edges of the load-bearing platform are respectively provided with flaps. One edge of the flap and the frame of the adjacent load-bearing platform are hinged and flipped through the hinge seat. The width of the flap is greater than the load-bearing The horizontal distance between the frame of the platform and the shear wall, and the outstretched edge of the flap is erected on the wall surface of the shear wall above the plane of the load-bearing platform;

The load-bearing platform is equipped with a scaffolding steel pipe limit insertion rod,

The bottom ends of the elevator shaft scaffolding are respectively inserted into the scaffolding steel pipe limit insertion rods for limit fixing, and the elevator shaft scaffolding is extended and installed upward along the elevator shaft.

The upper surface of the load-bearing platform and/or the turnover plate is covered with bamboo plywood or plywood.

A detachable connection is adopted between the load-bearing platform arranged horizontally above the load-bearing beam and the load-bearing beam.

Compared with the prior art, the utility model has the following beneficial effects:

The elevator shaft construction and protection platform is simple and easy to implement in the elevator shaft, and can be reused after a successful processing. It can be applied to elevator shafts of various sizes, saving manpower and material resources. The structure of the load-bearing beam and the load-bearing platform The strength can fully guarantee the strength and rigidity of the elevator shaft construction and the protection platform, which improves the safety during construction, avoids the safety problems caused by building scaffolding from bottom to top, effectively saves labor and time, and greatly shortens the project period. It has the function of horizontal protection to prevent objects from falling, reducing the safety hazards of working at heights.

The free end of the flap can rest on the shear wall, so that the load-bearing platform has a horizontal protection function to prevent objects from falling. The flip angle of the flap is free, so that the horizontal protection size of the load-bearing platform can be adjusted to adapt to common elevator shafts. There is almost no gap between the free end of the flap and the shear wall, which can prevent objects from falling, play the role of horizontal protection, and reduce the safety hazards of high-altitude operations, and the effect is better than that of the prior art.

The elevator shaft construction and protection platform has reasonable design, simple structure, easy processing, safety and reliability, convenient use and easy maintenance, and has good popularization and use value.
