Abstract
Description
Technical Field
[0001] The utility model relates to a reinforcing device for the elevator shaft structure of an aluminum alloy formwork, belonging to the technical field of formwork for elevator shaft construction. Background Art
[0002] The utility model belongs to the field of aluminum formwork for construction. Aluminum formwork is a building formwork made of aluminum alloy, and is a complete set of temporary structural systems composed of a formwork for forming concrete and its supporting system. As a new type of formwork system, aluminum alloy formwork has been widely used in high-rise and super high-rise buildings in China. It has the advantages of light weight, high strength, good stability, high load-bearing capacity, good concrete forming quality, good economic benefits, many times of circulation and use, short construction period, and low dependence on machinery, and is superior to traditional formwork.
[0003] The elevator shaft is an important part of high-rise buildings. Due to its special structure, its construction technology has become one of the main influencing factors of project quality, construction safety and overall progress. With the continuous popularization of high-rise residential buildings in the construction industry, the construction difficulty inside the elevator shaft gradually increases with the increase of building height.
[0004] Based on the formwork configuration method of the elevator shaft opening structure of the aluminum alloy formwork, the K board is used as the elevation board of the external wall formwork, playing a connecting role from top to bottom. Therefore, the reinforcement method of the upper formwork of the elevator shaft plays a crucial role in the forming quality of the external wall concrete. By optimizing the design scheme and construction technology of the reinforcement method of the upper formwork of the elevator shaft, its overall stability and durability can be improved, thereby effectively ensuring the safety and durability of the building structure.
[0005] Such as Figure 3 shown, the current generally adopted reinforcement device of adding double-tube back ribs on the external wall K board in the aluminum formwork construction system can better reinforce the upper formwork of the elevator shaft and solve the problems of formwork displacement, slurry leakage, large-area honeycombing, and shaft wall collapse at the elevator shaft opening position during the construction of aluminum alloy formwork. However, the double-tube back ribs act horizontally on the middle and lower parts of the upper formwork of the elevator shaft, and there is no effective fixing and straightening device at the top of the upper formwork of the elevator shaft, resulting in poor stability. The extrusion force during concrete pouring will still cause the formwork to displace, resulting in quality problems such as up-and-down offset and excessive verticality deviation after the external wall concrete is poured and formed, affecting the construction of subsequent processes and increasing the cost of secondary construction.
