Description

Technical Field

[0001] This application relates to the field of building technology, and in particular to aluminum formwork systems for composite slab floors. Background Technology

[0002] A concrete formwork system is a comprehensive construction system used for shaping freshly poured concrete. It includes the formwork itself and the supports used to hold it in place. The main function of the formwork is to provide the required shape and geometry for the concrete structure, ensuring that the concrete forms according to design requirements during the pouring process. The supports, on the other hand, maintain the formwork in its designed position during construction, ensuring its stability and accuracy. With the continuous development of construction technology, formwork technology is also constantly evolving, and various types of formwork are widely used in engineering construction. Among them, aluminum alloy formwork, as a new generation of formwork system following wooden and steel formwork, has gradually become a commonly used formwork system in modern building construction projects due to its unique advantages.

[0003] Aluminum alloy formwork boasts advantages such as precise dimensional accuracy, standardized specifications, convenient connection, and resistance to deformation. These characteristics significantly improve construction efficiency and quality while reducing construction difficulty and costs. For example, the standardized design and high-precision processing of aluminum alloy formwork ensure a tight fit between formwork panels, reducing errors and gaps during construction. Furthermore, the lightweight nature of aluminum alloy materials makes the handling and installation of formwork more convenient, further enhancing construction efficiency. In recent years, prefabricated construction, as a new building model, has gradually gained widespread attention and promotion due to its high degree of industrialization, high resource utilization efficiency, fast construction speed, low labor intensity, significantly reduced construction labor, wide applicability, and compliance with green building requirements. The core of prefabricated construction lies in the prefabrication of building components in a factory and then assembly on-site. This method not only effectively reduces resource waste and environmental pollution on construction sites but also significantly improves building quality and construction efficiency. With increasing environmental awareness and the acceleration of construction industrialization, prefabricated construction has broad development prospects and is expected to become a mainstream trend in the future construction industry.

[0004] In related technologies, when using composite slabs in building construction with aluminum formwork systems, local formwork is eliminated on the basis of fully cast-in-place aluminum formwork, forming a grid or "well" shape. C-shaped formwork is used at some intersections of the floor, requiring "well"-shaped bracing. This creates a cantilever structure at the C-shaped formwork locations (as in patent publication CN111946050A). This results in poor overall performance and structural strength of the aluminum formwork system, frequently leading to problems such as uneven floor or wall flatness and poor quality due to C-shaped formwork tipping over.

[0036] Research has revealed that current technologies using composite slabs in aluminum formwork systems for building construction involve eliminating some formwork sections on top of fully cast-in-place aluminum floor formwork, creating a grid or "well" shaped structure for the floor formwork. C-shaped formwork is used at some floor intersections, requiring "well" shaped bracing. This results in cantilever structures at the C-shaped formwork locations (as described in patent publication CN111946050A). This leads to poor overall integrity and structural strength of the aluminum formwork system, frequently resulting in uneven floor or wall flatness and poor quality due to C-shaped formwork tipping over.

[0037] See Figures 1-7 , Figures 1-5 A schematic diagram of the aluminum template system 1 in one embodiment of this application is shown. Figures 6-7A structural schematic diagram of the adjusting template group 100 in an embodiment of the present application is shown.
