Description

Technical Field

[0001] The utility model relates to the technical field of building templates, in particular to an aluminum-wood combined building template structure. Background Art

[0002] In the construction of prefabricated buildings, cast-in-place concrete structures usually use tool-type aluminum formwork construction technology. For the construction of standard floors, the aluminum alloy formwork designed and produced in advance based on the architectural drawings is relatively quick to install. However, for the construction of non-standard floors, due to the particularity of the building structure, it is difficult to achieve that the prefabricated aluminum formwork fully complies with the structural drawings and architectural drawings of the construction. It is often necessary to process and cut the aluminum formwork, and it is basically impossible to modify it during on-site installation. If there are indeed design changes, it is necessary to communicate with the manufacturer in advance, re-deepen the design, processing and production, and then transport it from the manufacturer to the construction site. This process will consume a lot of materials, which will lead to an increase in the cost of the project. The wooden formwork has the advantage of being easy to process and cut on site. The flexible wooden formwork can improve the problems of aluminum formwork in processing and correction. The aluminum-wood combined building formwork can complement each other's advantages and reduce the defects of a single aluminum formwork. The combination of the two can improve the project benefits and ensure the quality of the project. However, the difficulty of the aluminum-wood combined building formwork is the installation of the combined parts. If it is not handled properly, it is difficult to adapt to the construction requirements of the roof layer formwork and achieve the required strength and stability. Utility Model Content
