[0018] like Figures 1 to 5 The diagram illustrates an assembly structure for a steel-wood floor and floor screws, comprising a floor screw body 1 and a floor module. The floor module is composed of multiple base plates 2. Only a small portion of the floor module is shown in the diagram, containing two base plates 2. Each base plate 2 has a frame 3 at its bottom. The frame 3 is made of multiple metal profiles arranged along the edges of each base plate 2. Each metal profile is fixed to the bottom of the base plate 2 by welding or riveting, providing support for the base plate 2. Because the base plate 2 is a planar structure and the metal profiles are of regular shape, each base plate 2 and frame 3 can be easily prefabricated, and then the base plate 2 and frame 3 can be transported as a whole.

[0019] The ground screw body 1 is located at the connection node of the adjacent base plate 2. A cover plate 5 is installed on the top of the ground screw body 1. A connecting plate 4 is provided on the profile corresponding to the position of the ground screw. The connecting plate 4 is pre-welded to the frame 3. A connecting hole 6 is opened at the position corresponding to the cover plate 5. A fastener 7 is installed in the connecting hole 6. The connecting plate 4 and the cover plate 5 are fixedly connected by the fastener 7. The fastener 7 can be a threaded fastener 7 such as a screw, bolt and nut assembly, or other common fasteners 7. The base plate 2 is pre-fixed to the upper part of the frame 3 by nailing, and the connecting plate 4 is pre-welded to the lower part of the connection node of the frame 3.

[0020] Furthermore, the connecting holes 6 on the connecting plate 4 and the cover plate 5 are strip-shaped holes, and the opening directions of the two sets of strip-shaped holes are perpendicular to each other. The connecting holes 6 on the connecting plate 4 are arranged laterally, allowing the floor slab module to move laterally and compensating for lateral installation deviations; the connecting holes 6 on the cover plate 5 are arranged longitudinally, allowing for longitudinal installation deviations. The perpendicular strip-shaped holes create staggered friction surfaces after the bolts are tightened, and each connection node of each floor slab module is equipped with a fastener 7. The vibration energy of each connection node is dispersed and dissipated, preventing the fasteners 7 from loosening due to resonance.

[0021] The cover plate 5 is further configured as a rectangle, the ground screw body 1 is located at the lower center of the cover plate 5, and the connecting holes 6 are opened at the four corners of the cover plate 5. Each connecting hole 6 corresponds to a set of connecting plates 4. The four sets of connecting plates 4 are connected to the ground screw body 1 through a set of cover plates 5 to form a concentrated force transmission structure. The load is concentrated from the dispersed floor modules to the middle, reducing local stress deformation.

[0022] Furthermore, the connecting hole 6 is vertically offset from the frame 3, allowing the fastener 7 to be secured from both the upper and lower sides of the connection point between the cover plate 5 and the connecting plate 4. This provides fine-tuning space for the fastener 7 and reduces the assembly difficulty of the cover plate 5 and the connecting plate 4. Simultaneously, the fastening position of the connecting hole 6 is staggered from the connection point of the frame 3 and the connecting plate 4, resulting in a more uniform load transmission path.

[0023] Furthermore, the cover plate 5 is connected to the outer circumference of the ground screw with reinforcing ribs 8, which can significantly increase the bending strength of the node.

[0024] The assembly process of this embodiment is as follows: a cover plate 5 is pre-welded to the head of the ground screw, and the ground screw is driven vertically into the foundation so that the cover plate 5 protrudes to a set height; each base plate 2 is prefabricated, and the frame 3 is fixed to the bottom of the base plate 2 by welding, riveting, screwing, etc., and a connecting plate 4 is set at the node of the frame 3; each connecting plate 4 is aligned with the cover plate 5, and threaded fasteners 7 are installed in the connecting holes 6 of the connecting plate 4 and the cover plate 5 for fastening, thus completing the assembly of the floor module and the ground screw.

[0025] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
