Description

An elevator shaft construction platform

technical field

The utility model relates to the field of building construction safety, in particular to an elevator shaft construction platform.

Background technique

With the improvement of the degree of urbanization in our country, land resources are becoming more and more scarce. High-rise buildings can be used more effectively and rationally allocate limited land resources. A large number of high-rise and super high-rise buildings have been built all over the country, which has brought great impact to people's lives. convenience. However, the construction of high-rise buildings is difficult and has a high risk factor. Especially the elevator shaft inside the high-rise building has a high risk factor due to its vertical connection. Therefore, construction workers are carrying out wall reinforcement binding, formwork construction, concrete pouring, and formwork removal. For related construction work, a safe operation platform must be set up to facilitate construction. However, the traditional operation platform erection process is complicated and difficult to operate, the erection quality is not easy to guarantee, and the risk factor in the erection process is high. The patent document of the authorized announcement number CN 202090578 U mentions a special elevator shaft construction platform, but the patent structure is relatively complicated, the bottom width and the overall height are large, and it is difficult to lift up and down the elevator shaft and fix it. affect construction efficiency.

Utility model content

The utility model aims at the deficiencies of the prior art, and provides an elevator shaft construction platform with simple structure, reasonable design, safety and reliability, convenient hoisting, improved production efficiency and reduced cost.

In order to achieve the above object, the utility model provides an elevator shaft construction platform, which includes an operating platform and a bracket. The operating platform includes vertically and horizontally crossing beams to form a rectangular grid frame parallel to the floor. A support beam parallel to it, the two ends of the support beam are respectively facing the side of the elevator entrance of the hoistway and the opposite side of the elevator entrance;

The support includes a longitudinal beam connected to one end of the support beam located in the shaft on one side of the elevator entrance, the other end of the support beam is connected to a slanted beam, and the lower ends of the slanted beam are respectively connected to the longitudinal beam;

The side of the longitudinal beam located at the elevator entrance is provided with a card beam for supporting on the floor of the elevator entrance to prevent the support from sliding down.

Further, the beam of the frame near the side of the hoistway opposite to the elevator entrance is provided with a lead screw with a diameter of 36mm for tightening the hoistway wall.

A reinforcing beam is arranged between the longitudinal beam and the inclined beam.

The beams, supporting beams, longitudinal beams, inclined beams, reinforcing beams and card beams are all made of C14b channel steel.

When in use, after the concrete pouring of the elevator shaft on the lower floor is completed and the formwork is removed, the utility model is hoisted into the interior of the elevator shaft by a tower crane, and the card beam is supported on the floor of the lower structure. After the lower part is supported, the upper screw is tightened, so that The outer end of the operation platform is closely connected with the hoistway, which is convenient for construction personnel to perform work such as steel bar binding, formwork support, formwork removal, concrete surface repair, etc. on the operation platform. It is hoisted to the upper floor and continues to be used for turnover.

The beneficial effect of this scheme can be known from the description of the above scheme. It has simple structure, reasonable design, reasonable force, safety and reliability, improves the safety of elevator shaft construction and convenient operation, and speeds up construction and improves production. efficiency and reduce costs. The triangular shape on the side is convenient for lifting up and down in the elevator shaft, and it is convenient for fixed installation. It adopts the technical scheme of welding and forming C14b channel steel, which is convenient to use.

Detailed ways

In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

As shown in Figures 1-3, the utility model is a construction platform for an elevator shaft, including an operating platform 1 and a bracket 2. The operating platform 1 includes vertically and horizontally intersecting beams 3 to form a rectangular grid frame parallel to the floor, and the lower side of the frame is connected. There are two supporting beams 4 parallel to it, and the two ends of the supporting beams 4 are respectively facing the side of the elevator entrance 6 of the hoistway 5 and the side opposite to the elevator entrance 6; The longitudinal beam 7 connected at one end, the other end of the supporting beam 4 is connected with the inclined beam 8, the lower ends of the inclined beams 8 are respectively connected with the longitudinal beam 7, and a reinforcing beam 11 is arranged between the longitudinal beam and the inclined beam; the longitudinal beam 7 is located at the elevator entrance 6 One side is provided with the card beam 9 that is used to support on the floor 12 of the elevator entrance 6 to prevent the support 2 from sliding down. The frame is provided with a leading screw 10 that is used to tighten the shaft 5 wall diameter and is 36mm near the crossbeam 3 on the side of the shaft 5 opposite to the elevator entrance 6 . The beam 3, the supporting beam 4, the longitudinal beam 7, the inclined beam 8, the reinforcing beam 11 and the card beam 9 are all made of C14b channel steel.

During use, after the concrete pouring of the lower elevator shaft 5 is completed and the formwork is removed, the utility model is hoisted into the inside of the elevator shaft 5 by a tower crane, and the card beam 9 is supported on the lower structure floor 12. After the lower part is supported, the upper leading screw 10 is tightened with the hoistway wall 13, so that the outer end of the operation platform 1 is closely connected with the hoistway wall 13. After layer construction finishes, loosen lead screw 10, then by tower crane, it is hoisted to the upper layer to continue turnover and use.

The undescribed technical features of the utility model can be realized by or adopting the prior art, and will not be repeated here. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary skilled persons within the essential scope of the present utility model shall also belong to the protection scope of the present utility model.
