DETAILED DESCRIPTION

[0016] Embodiment 1:

[0017] like Figure 1-Figure 2 As shown, a large-span hollow floor steel filling component for preventing concrete from flowing in comprises a steel mesh box body 1, wherein the steel mesh box body 1 comprises a frame body 1-1, and each surface of the frame body 1-1 is fixedly provided with reinforcing ribs 1-2 in a criss-cross manner by welding, thereby effectively ensuring the structural strength of the steel mesh box.

[0018] The six external surfaces of the steel mesh box body 1 are respectively provided with dense mesh steel wire meshes 2, and the overlapping parts of each two adjacent dense mesh steel wire meshes 2 are respectively fixed with fixing components. Each of the fixing components includes two L-shaped first fixing members 3 and second fixing members 4, one end of the first fixing member 3 and the second fixing member 4 respectively penetrates the corresponding holes of the dense mesh steel wire mesh 2, and the other ends of the first fixing member 3 and the second fixing member 4 are close to each other and detachably provided with a connecting component.

[0019] In this embodiment, the connecting component is specifically configured as a connecting bolt 5, and the other ends of the first fixing member 3 and the second fixing member 4 are respectively provided with a first threaded hole 6 and a second threaded hole 7 adapted to the connecting bolt 5. After aligning the first threaded hole and the second threaded hole, the connecting bolt 5 is threadedly connected to the first fixing member and the second fixing member respectively, thereby realizing a detachable connection between the first fixing member and the second fixing member.

[0020] This new implementation of the invention provides a dense mesh steel wire mesh on the outside of the steel mesh box. When pouring concrete, the steel wire mesh can effectively prevent concrete from flowing into the hollow floor steel mesh box due to its blocking effect, thus ensuring smooth construction and improving the quality of the project. In addition, the utility model is easy to assemble and operate, does not require special equipment and tools, effectively controls the amount of concrete and reduces construction costs.

[0021] Embodiment 2:

[0022] like Figure 3As shown, without changing other structures of the first embodiment, the structure of the connecting assembly is adjusted. The connecting assembly in this embodiment includes a slide bar 8 slidably arranged on the first fixing member 3 and a socket 9 fixedly arranged on the second fixing member 4. The slide bar 8 is slidably matched with a slide hole 10 opened at the other end of the first fixing member 3. One end of the slide bar 8 is located on the outside of the first fixing member 3 and is fixedly provided with a pull rod 11 perpendicular thereto. The socket 9 is fixedly arranged on the outside of the second fixing member 4 and is provided with a socket 12 with the same inner diameter as the slide hole 10. The other end of the slide bar 8 is plugged and matched with the socket 12. A limiting ring 13 with a diameter larger than the inner diameter of the socket 12 is fixedly arranged in the middle of the slide bar 8, and a spring 14 is sleeved on the part located between the first fixing member 3 and the limiting ring 13. In this embodiment, the first fixing member and the second fixing member are plugged in and out of each other through the plug-in cooperation of the slide bar on the first fixing member 3 and the second fixing member. When disassembly is required, the first fixing member and the second fixing member can be separated by simply pulling the pull bar outward to make the slide bar slide outward and disengage from the plug-in seat. When installing, the pull bar is also pulled to align the slide bar of the first fixing member with the plug-in hole of the second fixing member. After the pull bar is released, the slide bar is inserted into the plug-in hole of the second fixing member under the action of the spring, thereby connecting the first fixing member and the second fixing member.
