The "prefabricated, formwork-free truss beam floor decking" disclosed in publication number "CN215167029U" is an increasingly mature technology. It states that "this utility model proposes a prefabricated, formwork-free truss beam floor decking, which reduces formwork removal construction, has good integrity and high rigidity, and can effectively improve the firmness and safety reliability of the floor slab, while achieving a certain structural bearing capacity." However, this floor decking still has the following drawbacks in use: [The text abruptly ends here, likely due to an incomplete translation or source material.] While the use of fixed rods and embedded parts can indeed reduce formwork removal and enhance stability and reliability, the prefabricated installation of the aforementioned floor decking structure is cumbersome. Furthermore, the simple structure of the floor decking results in insufficient structural strength. Therefore, it is necessary to provide a floor decking that significantly improves assembly convenience, enhances structural strength, and improves safety. Additionally, the current floor decking structure is heavy during transport, increasing transportation costs. Therefore, it is necessary to provide a floor decking that is easy to disassemble and transport, improving transport convenience and reducing transportation costs. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1-4 This utility model provides a prefabricated, formwork-free truss beam floor deck, including a floor deck assembly 100 and a truss beam assembly 200;

[0025] The truss beam assembly 200 includes several truss beam bodies 201 installed on the upper end of the floor deck body 101, and several fixed structures 202 are installed at equal intervals on the lower end of the several truss beam bodies 201.

[0026] The truss beam body 201 includes several upper chord members 2011, and web members 2012 are connected to both sides of the several upper chord members 2011. The lower ends of the two web members 2012 are connected to lower chord members 2013.

[0027] The fixed structure 202 includes several bases 2021 installed at the lower ends of the two lower chord rods 2013. The upper ends of the bases 2021 are symmetrically provided with matching grooves 2022, and the two lower chord rods 2013 are engaged inside the matching grooves 2022.

[0028] In one specific embodiment, the combination of the floor decking body 101 and the truss beam assembly 200 not only significantly improves the ease of prefabricated installation, but also enhances the overall structural strength of the floor decking through the interplay of these structures, thereby improving its practicality. Furthermore, the modular floor decking structure facilitates improved transport efficiency and reduces cost losses, making it easier to promote and use. During use, the modular structure of the truss beam assembly 200 and the floor decking body 101 allows for easy separate transport, followed by the connection of several upper chord members 2011 with the web... The welded structure of the rod 2012 and the lower chord 2013 and the floor deck body 101 are embedded in each other, which not only initially enhances the connection strength between the truss beam assembly 200 and the floor deck body 101, but also improves the convenience of the assembly operation and the installation efficiency. Several bases 2021 in the fixed structure 202 are embedded in the floor deck body 101. At this time, the lower chord 2013 is engaged in the fitting groove 2022, which can further enhance the overall structural strength while improving the connection convenience, thereby enhancing the service life of the floor deck.

[0029] Please see Figure 2 The upper end of the floor deck 101 is equipped with several limiting mechanisms 102. Each limiting mechanism 102 includes several supports 1021 that are symmetrically and equidistantly installed on the upper end of the floor deck 101. Each support 1021 has a positioning rod 1022 inserted inside it.

[0030] In one specific embodiment, several positioning rods 1022 in the limiting mechanism 102 are inserted into the support 1021 to perform lateral limiting operations on the truss beam assembly 200, thereby further enhancing the overall strength of the floor deck and improving safety in use.

[0031] Please see Figure 3 and Figure 4 The support 1021 has a connecting hole 111 on its surface. The positioning rod 1022 is inserted into the connecting hole 111. The upper end of the floor deck body 101 has several positioning holes 112. The two ends of the upper chord 2011 and the lower chord 2013 are inserted into the positioning holes 112.

[0032] In one specific embodiment, the connecting hole 111 can improve the connection stability between the positioning rod 1022 and the support 1021, and the positioning hole 112 can further embed and position the upper chord 2011 and the lower chord 2013, thereby improving the connection strength between the truss beam assembly 200 and the floor deck body 101.

[0033] Please see Figure 3 and Figure 4 Both ends of the upper chord 2011 and the lower chord 2013 are fixedly connected to a screw tube 211, and the screw tube 211 is internally threaded with a bolt 212.

[0034] In one specific embodiment, the bolt 212 is threaded inside the screw tube 211, thus the bolt 212 can help enhance the connection strength between the upper chord 2011 and the lower chord 2013.

[0035] Please see Figure 3 and Figure 4 A connecting piece 221 is fixedly connected to the lower end of the base 2021. The connecting piece 221 is made of stainless steel.

[0036] In one specific embodiment, the connecting piece 221 can increase the contact area between the base 2021 and the floor deck body 101, thereby improving stability. The stainless steel connecting piece 221 can avoid being corroded by concrete and extend the service life of the base 2021.

[0037] Please see Figure 3 and Figure 4 The lower end of the connecting piece 221 is fixedly connected to two limiting protrusions 231 and several friction ribs 232, and the limiting protrusions 231 and friction ribs 232 are all embedded inside the floor deck body 101.

[0038] In one specific embodiment, the limiting protrusion 231 and several friction ribs 232 can enhance the connection strength between the base 2021 and the floor deck body 101, and further improve the connection stability between the truss beam body 201 and the floor deck body 101.

[0039] Please see Figure 3 and Figure 4 The upper chord 2011, web member 2012 and lower chord 2013 are all made of steel bars and are welded together.

[0040] In one specific embodiment, the upper chord 2011, web member 2012, and lower chord 2013 of the steel welded structure can significantly enhance the compressive and tensile strength of the truss beam assembly 200.

[0041] Working principle: During use, the separate structure of the truss beam assembly 200 and the floor deck body 101 facilitates separate transportation. Through the welded structure of several upper chords 2011, web members 2012, and lower chords 2013, and the floor deck body 101, the connection strength between the truss beam assembly 200 and the floor deck body 101 is initially enhanced, while also improving the convenience of assembly operations and installation efficiency. In addition, several bases 2021 in the fixing structure 202 are embedded and connected to the floor deck body 101. By engaging the lower chord 2013 in the fitting groove 2022, the overall structural strength is further enhanced while improving the connection convenience. Therefore, the safety of the floor deck and the assembly efficiency are improved.
