Description

Technical Field

[0001] The utility model belongs to the technical field of assembled floor slabs, and particularly relates to an assembled floor slab with a weight-reducing structure. Background Art

[0002] The weight reduction effect of prefabricated floors is relatively limited. Although prefabricated floors use lightweight materials or structural designs, it is difficult to achieve significant weight reduction effects because the floors need to meet certain strength and stiffness requirements. In addition, the modular characteristics of prefabricated floors also limit the possibility of weight reduction, because modular components still need to be connected, which adds a certain amount of weight. There are many reasons for these shortcomings. First, the design and material selection of the floor may not fully consider the requirements for weight reduction. Second, based on construction considerations, prefabricated floors need to meet certain standard dimensions and load requirements, which limits the designer's freedom.

[0003] Conventional coping methods include using lightweight materials, such as polystyrene boards, foam concrete, etc., to reduce the weight of the floor. In addition, hollow structure design can also be used to reduce the amount of materials used. In addition, optimizing the layout and structure of the floor and reducing the deadweight of the load structure are also common methods. However, these methods also have some disadvantages. First, lightweight materials may sacrifice the strength and rigidity of the floor, thereby affecting the performance and safety of the floor. For hollow structure design, the complexity of the structure may be increased, and the construction difficulty will also increase accordingly. In summary, the existing prefabricated floor has certain limitations in weight reduction. The lack of significant weight reduction effect, limited by modular characteristics, design, material selection and other factors, makes weight reduction difficult. Although conventional coping methods can reduce the weight of the floor to a certain extent, there are also some disadvantages, such as sacrificing the performance of the floor and the difficulty of construction. Therefore, we hope to design a prefabricated floor with a new structure to solve this problem. Utility Model Content
