The technical solution of this utility model is: a prefabricated floor construction support tool component, including an aluminum alloy beam, an aluminum alloy beam support, a support pole, and a support stabilizing frame. The aluminum alloy beam is mainly used to bear the load related to the prefabricated floor and is directly in contact with the prefabricated floor. The aluminum alloy beam support is not only used to fix the aluminum alloy beam but also acts as a carrier connected to the support. The support pole is mainly used to support the carrier for indirect force transmission of the aluminum beam. The support stabilizing frame is mainly used to stabilize the support pole to prevent it from tilting. Features of this utility model patent: In the construction of prefabricated prefabricated floor, the prefabricated floor construction support tool has the characteristics of light weight, less material, and convenient manual handling compared to the traditional full-frame body. It can be simply and quickly used in the installation and construction of prefabricated floor with high efficiency.
