Description

Technical Field

[0001] The utility model relates to a field, in particular to a fast-assembly elevator shaft construction operation platform. Background Art

[0002] Since the 21st century, my country's rapid economic development has led to rising demands for living conditions, the expansion of cities, and a growing urban population, resulting in a continued surge in demand for urban housing. The construction industry needs to apply new construction technologies to meet this demand. Furthermore, given limited land resources, high-rise buildings can be constructed to meet housing needs and effectively utilize land resources. High-formwork construction technology is a widely used construction technique. Its development offers new opportunities for construction projects and represents a novel approach to civil engineering. While effective application of high-formwork construction technology can improve project quality and ensure the safety of construction workers, this technology still has limitations. The overall construction process is complex and subject to numerous restrictive factors. Therefore, construction companies need to effectively understand key construction techniques, thoroughly explore the application of high-formwork construction technology, and develop targeted measures to ensure construction quality.

[0003] In a type of high-rise building, the elevator shaft is a core tube concrete structure, and its height exceeds the requirements of the "Safety Technical Specifications for Coupler-Type Steel Pipe Scaffolding in Building Construction" (JGJ130-2011). It is not convenient to use full-height scaffolding for construction. Even if full-height scaffolding is used for construction, the height of each floor cannot exceed 20m. It needs to be erected in sections, which is complicated and expensive, and very uneconomical. In order to facilitate the construction of elevator shafts in such buildings, a new construction tool needs to be proposed to meet the corresponding construction needs. Utility Model Content

[0004] The purpose of the utility model is to provide a fast-assembly elevator shaft construction operation platform to solve the problem of complex process and high cost when the elevator shaft construction of a type of high-rise building adopts full-height scaffolding.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A quickly assembled elevator shaft construction operation platform includes a bottom channel steel diagonal brace, a diagonal brace connecting steel pipe, a vertical support steel pipe, a lower horizontal support steel pipe and an upper horizontal support steel pipe. The bottom end of the bottom channel steel diagonal brace is provided with a "V"-shaped slot, and the "V"-shaped slot is connected to the concrete beam support on one side of the shaft. The upper end of the bottom channel steel diagonal brace is connected to the concrete wall support on the other side of the shaft. The diagonal brace connecting steel pipes are evenly arranged on the top of the bottom channel steel diagonal brace. The vertical support steel pipe is arranged vertically, and the lower part of the vertical support steel pipe is connected to the bottom channel steel diagonal brace. The lower horizontal support steel pipe and the upper horizontal support steel pipe are respectively arranged at the lower and upper parts of the vertical support steel pipe. The top of the upper horizontal support steel pipe is also overlapped with a supporting wooden board, and the top of the vertical support steel pipe is also provided with a hook.

[0007] When installing the elevator shaft construction operation platform, use a tower crane to hook the hook, then hoist the elevator shaft construction operation platform to the elevator shaft construction area, and then slowly lower it so that the reserved "V"-shaped slot at the lower end of the bottom channel steel diagonal brace is stuck to the door head concrete beam of the elevator shaft, and the reserved inclined surface at the upper end of the bottom channel steel diagonal brace is placed on the concrete wall, thus forming a supporting structure, on which the construction of this layer of concrete components can be carried out; after the construction of this layer of concrete components is completed, wait until the formwork is removed and the garbage and other materials on the platform are cleared, and the subsequent installation of each layer is similar;

[0008] After the construction of the last floor is completed, the elevator shaft construction operation platform will be hoisted out of the elevator shaft, placed at the designated location, cleaned up the garbage and dismantled. The construction of the machine room floor uses the original 16#a channel steel as support and is placed on the concrete components of the elevator shaft. A hole is reserved here to facilitate later demolition. After the 16#a channel steel of the machine room floor is dismantled, the garbage is cleaned up and dismantled for later turnover use.

[0009] The use of this elevator shaft construction operation platform ensures safety, reduces costs, achieves green construction, and improves overall benefits.

[0010] As a further preferred embodiment of the present invention, each support member of the bottom channel steel diagonal brace is formed by two channel steels stacked up and down, and a steel bar cut is fully welded between the two channel steels.

[0011] When welding broken steel bars onto channel steel, the weld must be complete.

[0012] As a further preferred embodiment of the present invention, the broken end of the steel bar is welded to the channel steel on both sides, and the broken end of the steel bar is also welded to the lower part of the vertical supporting steel pipe.

[0013] As a further preferred embodiment of the present invention, the specification of the channel steel is 160*63*6.5mm

[0014] As a further preferred embodiment of the present invention, the supporting wooden board and the upper horizontal supporting steel pipe are bound together by iron wire, and the iron wire is No. 8 iron wire.

[0015] As a further preferred embodiment of the present invention, the specification of the steel pipe is φ48*3.2mm.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] 1. Under the combined action of 1.3 times the constant load + 1.5 times the live load, the operating platform's bending, shear, deflection, support reaction and other stress conditions all meet the requirements of the specifications.

[0018] 2. Using this elevator shaft construction operation platform ensures safety, reduces costs, achieves green construction, and improves overall benefits.

[0019] 3. Simple structure and easy to make. BRIEF DESCRIPTION OF THE DRAWINGS
