Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction, in particular to a combined connection and fixing device of an aluminum template and a wooden template. Background Art
[0002] Aluminum formwork has higher durability than disposable wooden formwork and can be used repeatedly in multiple projects, thus reducing material costs. In addition, aluminum formwork is lightweight and easy to carry and install, making the construction process more efficient. Its high manufacturing precision and smooth surface help improve the quality and appearance of concrete pouring, so it is widely used in the construction field.
[0003] However, since aluminum formwork is a standard part with fixed size, when non-standard building floors have different heights during construction, it is often necessary to install wooden formwork on top of the aluminum formwork used for standard floors to compensate for the insufficient height of the aluminum formwork.
[0004] This requires that the aluminum formwork and the wooden formwork be fixedly connected together during construction. At present, there is no effective and safe connection method and device for this type of construction method. Often, when pouring concrete, it will cause problems such as concrete expansion, mold explosion, and deviation at the connection part, resulting in construction quality defects and unnecessary repair costs.
