Embodiment

[0021] Embodiment: a construction method of aluminum alloy formwork with variable cross-section structure, comprising the following steps:

[0022] (1) Aluminum formwork design: According to the structural drawings of the office building, structural analysis is carried out, and in view of the characteristics of the office building with many floor changes and variable cross-sections, it mainly analyzes and plans the structure type, structural variable cross-section, and distribution of special-shaped structures, etc. In particular, it is necessary to focus on the location and distribution of variable sections such as frame columns, shear walls, and frame beams, because the above variable sections will have a greater impact on formwork matching; for special-shaped structures of office buildings, more in-depth deepening must be carried out Design, this work will have a great impact on the amount of aluminum mold matching engineering, so overall consideration, improving the degree ...

Abstract

The invention discloses a variable-cross-section aluminum alloy formwork construction method which comprises the following steps of aluminum formwork design, aluminum formwork preparation, aluminum formwork supporting frame body construction, aluminum formwork construction including frame column ending cross section construction, shear wall ending cross section construction and frame beam ending cross section construction. According to the method, aluminum alloy formworks are adopted in super high-rise office buildings of 100 meters or above, advanced deepening and comprehensive overall planning are conducted on nonstandard layers, special-shaped structures and floors and parts having structure size change, meanwhile supporting frame bodies with the floor height of 4.1 meters or below areimproved and optimized in form, and application of aluminum alloy formworks in super high-rise office buildings is successfully achieved.

Description

technical field [0001] The invention relates to a construction method, in particular to an aluminum alloy formwork construction method suitable for most super high-rise office buildings and office buildings with a height less than 100 meters and large structural changes. Background technique [0002] In recent years, with the country's advocacy and promotion of green buildings, prefabricated buildings, and environmental protection construction requirements, combined aluminum alloy formwork has been more and more used in formwork construction in construction projects. The aluminum alloy formwork has the advantages of high strength, many turnover times, good forming effect, fast construction speed, and early demolition. At the same time, the unit weight of the aluminum alloy formwork is lighter than the traditional steel formwork, which is convenient for construction personnel to carry and disassemble. Construction Schedule. [0003] When the aluminum alloy formwork is applie...
