As an important component of modern industrialized construction, precast components are widely used in various types of buildings, especially prefabricated buildings. Their use not only improves construction efficiency and quality but also promotes the sustainable development of the construction industry. With continuous technological advancements and innovation, precast components will play an even more important role in the future construction field.

[0003] In existing technologies, prefabricated building components are generally used to speed up construction. However, the connections of existing prefabricated building components are unstable during use, which can easily lead to concrete leakage and deformation of the prefabricated building components. At the same time, the two ends of the prefabricated building components need to be welded to form a preliminary fixation, and there is no effective support, which causes a decrease in the efficiency of the prefabricated building components. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a steel truss floor deck that is easy to assemble and install. This deck can facilitate auxiliary support for precast building components, and allows for easy overlapping of the two sides of the precast building components to avoid deformation. This solves the problems of unstable connections at the joints of existing precast building components during use, which can easily lead to concrete leakage and deformation of the precast building components. In addition, the precast building components require welding at both ends to form a preliminary fixation, and there is no effective support, which reduces the efficiency of the precast building components.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steel truss floor deck that is easy to assemble and install, comprising a profiled steel sheet, wherein a truss structure for support is fixedly connected to the top of the profiled steel sheet, and bracket structures for use with the truss structure are provided on the front and rear sides of the profiled steel sheet, and a boss connection structure for use with another profiled steel sheet is provided on the right side of the profiled steel sheet.

[0006] Furthermore, the truss structure includes web reinforcement bars, the bottom of which is fixedly connected to the top of the profiled steel sheet. The number of web reinforcement bars is several and they are evenly distributed. The web reinforcement bars are arranged in a wavy pattern. An upper chord reinforcement bar is fixedly connected to the top of the web reinforcement bar, and a lower chord reinforcement bar is fixedly connected to the bottom of the web reinforcement bar. The bottom of the lower chord reinforcement bar is welded to the profiled steel sheet. The upper and lower chord reinforcement bars are used in conjunction with the bracket structure.

[0007] Furthermore, the bottom of the lower chord steel bar is fixedly connected with a reinforcing bar, the number of the reinforcing bars is several and they are evenly distributed, a first groove is provided on the left side of the profiled steel sheet, a second groove is provided on the right side of the profiled steel sheet to cooperate with the first groove, and the boss connection structure is set in the second groove.

[0008] Furthermore, the bracket structure includes a support plate, the top of which is used in conjunction with the bottom of the profiled steel sheet, and a snap-fit ​​plate is fixedly connected to the side of the support plate. Both ends of the upper chord steel bar and the lower chord steel bar are fixedly connected with connecting protrusions that cooperate with the snap-fit ​​plate.

[0009] Furthermore, the boss connection structure includes a rotating seat, the surface of which is fixedly connected to the interior of the profiled steel sheet, a vertical rod fixedly connected to the interior of the rotating seat, a support block fixedly connected to the bottom of the vertical rod, and a U-shaped plate fixedly connected to the top of the vertical rod for rotating the vertical rod and connecting the horizontal reinforcing bars.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model improves the stability and load-bearing capacity of the structure by setting up profiled steel sheets, truss structures, bracket structures and boss connection structures. The fixed connection of the truss structure provides strong support for the profiled steel sheets and enhances the overall rigidity. The cooperation between the bracket structure and the truss structure stabilizes the installation position of the profiled steel sheets and prevents them from shifting. The boss connection structure facilitates the tight connection between multiple profiled steel sheets to form a stable structure.

[0013] 2. This utility model improves structural stability by setting up a truss structure. The wavy design of the web reinforcement enhances the overall rigidity of the truss, allowing the structure to better distribute stress when under load. The cooperation of the web reinforcement, top chord reinforcement, and bottom chord reinforcement forms a stable triangular support structure, improving overall stability. The uniform distribution of the bottom reinforcement reinforcement at the bottom of the bottom chord reinforcement enhances the connection strength between the truss and the profiled steel sheet, making the entire structure more robust and reliable. The first and second grooves on the profiled steel sheet, as well as the boss connection structure, facilitate quick connection with other trusses.

[0014] 3. By setting up a bracket structure, this utility model can improve the connection stability between the profiled steel sheet, the upper chord steel bar, the lower chord steel bar and the main building structure. The top of the bracket is used in conjunction with the bottom of the profiled steel sheet, so that the profiled steel sheet can be placed firmly on the bracket and is not easy to shift. The snap-fit ​​buckle plate fixedly connected to the side of the bracket cooperates with the connecting protrusions fixedly connected to both ends of the upper chord steel bar and the lower chord steel bar to form a reliable snap-fit ​​structure, so that the upper chord steel bar and the lower chord steel bar can be firmly fixed on the bracket, enhancing the stability of the entire structure.

[0015] 4. This utility model can effectively achieve a stable connection between the rotating seat and the profiled steel sheet by setting a boss connection structure. At the same time, the cooperation of the upright, the support block and the U-shaped plate enhances the load-bearing capacity of the structure. The connection between the two profiled steel sheets is achieved by rotating the upright and the support block. When the upright rotates, the upright will drive the U-shaped plate to rotate. The steel bar is inserted into the groove of the U-shaped plate to form a stable lateral fixation. Attached Figure Description
