[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3An embodiment of this utility model provides: a prefabricated steel truss floor deck, comprising: a floor deck body 1, a first mounting block 7 fixedly connected to the top of the floor deck body 1, a bearing rod 6 fixedly connected to the top of the first mounting block 7, the bearing rod 6 being installed horizontally on the top of the first mounting block 7, a second mounting block 8 installed on the top of the floor deck body 1, the bearing rod 6 fixedly connected to the top of the second mounting block 8 being installed vertically, a fixing rivet 9 installed at the bottom of the second mounting block 8, the fixing rivet 9 being installed on the top of the floor deck body 1, a second fixing block 4 fixedly connected to the outer wall of the floor deck body 1, a second fixing hole 5 being opened inside the second fixing block 4, and a plurality of first fixing blocks 2 fixedly connected to the side wall of the floor deck body 1, the first fixing blocks 2 being provided with first fixing holes 3.

[0021] Specifically, firstly, a floor deck slab body 1 equipped with a second fixing block 4 is precisely fixed to a predetermined position in the load-bearing area using bolts to engage with the first fixing block 2, ensuring its firmness and reliability. Then, the connecting block 10 of the next floor deck slab body 1 is carefully and precisely installed into the connecting groove 12 opened on one side of the floor deck slab body 1 from above. This tight fit ensures a secure fixation, preventing displacement during subsequent construction. This process is repeated to gradually complete the splicing and installation of multiple floor deck slab bodies 1 until the last floor deck slab body 1 is also fixed. At this point, the L-shaped first mounting block 7 and second mounting block 8 at the top can stably fix the top load-bearing rod 6, thereby greatly increasing the overall structural strength and load-bearing capacity of the floor deck slab.

[0022] Reference Figure 2 and Figure 3 A connecting block 10 is fixedly connected to one side of the floor deck body 1. The connecting block 10 is I-shaped. A connecting groove 12 is opened on the side of the floor deck body 1 away from the connecting block 10. The connecting groove 12 is correspondingly set as an I-shaped inner groove. A third fixing block 11 is fixedly connected to one side of the floor deck body 1, located outside the connecting block 10. A fixing groove 13 is opened on one side of the floor deck body 1, located outside the connecting groove 12. A fixing screw 14 is threaded through the inside of the third fixing block 11 and is threaded to the top of the floor deck body 1.

[0023] Specifically, after the first floor deck slab body 1 is installed, the connecting block 10 installed on the outside of the second floor deck slab body 1 is aligned and inserted into the connecting groove 12 opened on one side of the first floor deck slab body 1, ensuring a tight fit and stability. Then, using the third fixing block 11 installed on the second floor deck slab body 1, the internal fixing screw 14 is aligned with the fixing groove 13 opened on the top of the first floor deck slab body 1, and the two are securely connected by a threaded connection. This connection method not only enhances the connection strength between the floor deck slab bodies 1, but also effectively prevents floor deck displacement or leakage at the connection point during subsequent pouring operations, ensuring the stability and reliability of the entire structure.

[0024] Working Principle: First, during the initial installation of the main floor deck slab 1, the second fixing block 4, in conjunction with bolts, precisely connects it to the first fixing block 2, firmly fixing it in the weighing area and ensuring the stability of the initial position. This structural design provides a solid foundation for subsequent splicing. Next, the subsequent splicing of the main floor deck slab 1 is carried out. The connecting block 10 of the next main floor deck slab 1 is slowly inserted into the connecting groove 12 of the previous main floor deck slab 1. The I-shaped connecting block 10 fits tightly with the connecting groove 12, forming a stable lateral connection. In addition, the fixing screw 14 inside the third fixing block 11 is threadedly connected to the fixing groove 13 at the top of the main floor deck slab 1, further enhancing the longitudinal connection strength. This structure effectively prevents the displacement of the main floor deck slab 1 after splicing, ensuring the stability of the structure. At the top of the main floor deck slab 1, the L-shaped first mounting block 7 and the second mounting block 8 fix the load-bearing rod 6 in the lateral and longitudinal directions, respectively. Under the combined action of the first mounting block 7 and the second mounting block 8, the load-bearing rod 6 forms a stable steel truss structure, evenly distributing the load and enhancing the overall load-bearing capacity and structural rigidity of the floor deck slab. After all the floor deck slabs 1 have been spliced ​​and secured, concrete pouring is carried out. The robust connection structure between the floor deck slabs 1 effectively prevents displacement or leakage at the joints during pouring, ensuring the quality of the concrete pour. The stable steel truss structure and concrete create a good composite effect, further improving the overall performance of the floor slab and meeting the building structure's requirements for load-bearing capacity, durability, and safety.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
