Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-rise building construction, in particular to a construction method combining aluminum formwork and wooden formwork for non-standard layer structure. BACKGROUND

[0002] At present, the commonly used formwork for concrete pouring mainly includes steel formwork, wooden formwork, bamboo formwork, plastic formwork, etc. However, these traditional formworks have low durability, high cost, or insufficient strength, which leads to problems in construction quality, construction efficiency and construction safety, which are difficult to effectively control. The aluminum alloy formwork system adopts the concept of design first, realizes the one-time forming of wall pile and over two through in-depth design of structure, and has better quality than the national standard, thereby realizing the plaster-free process of wall body, and is widely used in the current construction market.

[0003] At the same time, with the application of new technologies in the construction industry and the development of the industry, the use of aluminum alloy formwork has become a common formwork system in the construction industry. According to the construction market research, it is mainly used for standard layer concrete components of high-rise residential projects. Not only the concrete component forming quality is good, the construction efficiency is high, the material turnover rate is high, but also the project construction cost can be saved. However, for low floor type projects, especially for non-standard floor projects of public buildings, if only aluminum alloy formwork is used, the construction cost is high, and the aluminum alloy formwork turnover frequency is low due to the changeable vertical structure size. The wooden formwork system is a traditional formwork system, which has been widely used in the industry, and is suitable for various types of building concrete components, and has the advantages of strong plasticity, etc. Therefore, the combination of aluminum formwork and wooden formwork can not only reflect the advantages of aluminum formwork assembly type construction, but also reflect the advantages of low cost of wooden formwork, which can effectively solve the problem of difficulty in supporting aluminum alloy formwork at non-standard layer structure. However, in the actual operation process, the following problems are still difficult to effectively solve:

[0004] 1. Due to the different deformation capabilities of aluminum formwork and wooden formwork, and the difficulty in connecting aluminum formwork and wooden formwork between the upper standard layer and the non-standard layer under construction, it is easy to cause misalignment and deformation of wooden formwork after pouring, which leads to poor structural stability, not only causing inconvenience in subsequent repair, but also causing rework and other problems.

[0005] 2. In some high structure column, because the aluminum alloy formwork can be connected by the support and fastener in the aluminum alloy formwork system, so that it can ensure stable support when grouting the structure column to a certain height, but the wooden formwork can only provide independent support system formed by counter-bolt and other measures, which leads to poor combination performance of aluminum alloy formwork and wooden formwork during support, and cannot effectively ensure the integrity of the structure column after pouring; at the same time, the wooden formwork has poor deformation resistance when subjected to the pressure of concrete slurry, so that only relying on single counter-bolt and other measures cannot effectively support the wooden formwork, and the formwork position is easy to deviate and swell during pouring;

[0006] Therefore, in view of the above problems, it is urgent to design a new connecting structure and construction method of the combination of non-standard layer structure aluminum formwork and wooden formwork to solve the problems existing in the prior art. SUMMARY
