Description

Technical Field

[0001] The utility model relates to the technical field of steel platforms for elevator shaft operations, and specifically to a steel platform for the construction field. Background Technique

[0002] In the construction operation of building elevator shafts, a steel platform is a temporary working platform used in the construction of elevator shafts in high-rise and super-high-rise buildings. The main function of this steel platform is to provide a safe and stable working environment for workers to carry out construction operations in the elevator shaft. In traditional scaffolding construction, due to the high erection height, there are safety hazards, high costs, and inconvenient operations. Therefore, in actual operations, various forms of standardized tool-type elevator shaft operation platforms are adopted. These platforms have the advantages of high safety performance, convenient operation, and low cost, and have strong practical application and promotion value.

[0003] The elevator shaft bodies of various building construction projects have the characteristics of being continuous up and down, having thick shaft walls, and few opening positions. Therefore, the construction operations in this part have always been the key points in the risk source control of each project. Currently, the following two methods are mostly used to implement the elevator shaft operation scaffolds:

[0004] 1. Embedded I-beams are used to erect a steel pipe scaffold working platform: This method is relatively cumbersome and requires steps such as embedding, erection, and demolition. At the same time, it will increase the rental volume of turnover materials, and the quality of manual erection depends on the construction quality of the operators. Therefore, safety accidents are likely to occur; this method will have adverse effects in terms of construction period, safety, cost, etc.

[0005] 2. Adopt a prefabricated steel platform: This method only needs to be lifted by a tower crane to achieve rapid erection. However, this platform does not effectively solve the protection of elevator openings and additional protective frameworks need to be erected; at the same time, there is no horizontal protection at the position of the steel platform. Therefore, the method of increasing the platform size is usually adopted to reduce the gap between the framework and the structure. This solution greatly increases the lifting difficulty of the framework. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a steel platform for the construction field, which has the advantages of improving the safety of operations inside the elevator shaft, reducing the lifting difficulty of the framework, and having favorable effects on the construction period, safety, cost, etc.

[0007] To achieve the above object, the utility model provides the following technical solution: A steel platform for the construction field, used for elevator shaft operations, includes a platform board suspended inside the elevator shaft and a support framework fixed to the bottom of the platform board. A wire mesh is arranged on the side wall of the support framework, and a protective steel plate is welded on the side wall of the support framework.

[0008] The side wall of the platform plate is hinged with a horizontal flap through a hinge, and a plurality of lifting rings are fixed on one side of the platform plate away from the support skeleton.

[0009] Furthermore, a metal pressing strip is arranged on one side of the wire mesh away from the support skeleton, and the metal pressing strip is fixed on the support skeleton through bolts.

[0010] Furthermore, the number of the lifting rings is set to four, and the platform plate is a checkered steel plate.

[0011] Furthermore, the protective steel plate and the wire mesh are installed on the same side wall of the support skeleton.

[0012] Furthermore, the support skeleton is formed by welding a plurality of C-shaped steel channels.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] The steel platform for construction elevator shaft operation increases the horizontal protection of the edge of the elevator shaft opening and the operation platform through the settings of the wire mesh, the protective steel plate and the horizontal flap, ensures the safety of the operation inside the elevator shaft, and at the same time reduces the difficulty of lifting the frame, which can have a favorable impact on the construction period, safety, cost, etc. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , a steel platform for the construction field in this embodiment includes a platform board 3 suspended in an elevator shaft 1 and a support skeleton 5 fixed to the bottom of the platform board 3. A wire mesh 6 is provided on the side wall of the support skeleton 5, and a protective steel plate 7 is welded on the side wall of the support skeleton 5. The support skeleton 5 is formed by welding a plurality of C-shaped steel channels.

[0023] Among them, the edge position of the support skeleton 5 is fixed at the edge of the structural floor 2.

[0024] A horizontal flap 10 is hinged to the side wall of the platform board 3 through a hinge 9, and a plurality of lifting rings 4 are fixed on the side of the platform board 3 away from the support skeleton 5.

[0025] In this example, a metal pressing strip 8 is provided on the side of the wire mesh 6 away from the support skeleton 5, and the metal pressing strip 8 is fixed to the support skeleton 5 by bolts.

[0026] Among them, a plurality of metal pressing strips 8 are provided, and the metal pressing strips 8 are used to fix the wire mesh 6 to the support skeleton 5, and the wire mesh 6 and the protective steel plate 7 have the effect of temporarily protecting the elevator well opening.

[0027] It should be noted that through the settings of the wire mesh 6, the protective steel plate 7 and the horizontal flap 10, the edge protection of the elevator shaft opening and the horizontal protection of the working platform are increased, ensuring the safety of operations inside the elevator shaft body, while reducing the difficulty of lifting the frame body, which can have a beneficial impact on the construction period, safety, cost, etc. The specially designed elevator shaft steel platform can effectively improve the safety of operations and speed up the construction progress. The specially designed horizontal flap 10 can effectively provide horizontal protection, can reduce the platform size to a certain extent, and reduce the difficulty of lifting the frame body. The hole protection plate integrated with the frame body can quickly provide effective protection for the elevator hole, and can effectively reduce the probability of safety accidents.

[0028] Please refer to Figure 4 , the number of lifting rings 4 is set to four, and both the platform board 3 and the protective steel plate 7 are diamond plates.

[0029] Among them, the protective steel plate 7 and the wire mesh 6 are installed on the same side wall of the support skeleton 5.

[0030] The working principle of the above embodiments is as follows: Before the operation on the standard floor (the non-standard floor is not applicable to the standard floor due to the floor height), the platform is designed according to the actual size of the elevator shaft. The formwork of the shaft body and its support system are removed, and the materials are transported to the operation floor. Then, the steel platform is hoisted into place (below the operation floor) by a tower crane. The edge protection of the opening of the hoisting layer is erected synchronously. Then, the horizontal flap 10 is opened, and the formwork installation operation can be started. Through the settings of the wire mesh 6, the protection steel plate 7, and the horizontal flap 10, the horizontal protection of the edge of the elevator shaft opening and the operation platform is increased, ensuring the safety of the operation inside the elevator shaft and at the same time reducing the difficulty of hoisting the framework, which can have a favorable impact on the construction period, safety, cost, etc.
