[0029] To better explain and facilitate understanding of this utility model, the following detailed description of the utility model, in conjunction with the accompanying drawings and specific embodiments, is provided.

[0030] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0031] Reference Figure 1 and Figure 2A connecting component between a precast concrete composite floor slab and an H-shaped steel beam includes: a lower flange 1, a web 2 fixedly installed on the top of the lower flange 1, an upper flange 3 fixedly installed on the top of the web 2, a first composite floor slab 8 installed on the top of the upper flange 3, a connecting plate 7 installed on the top of the first composite floor slab 8, the first composite floor slab 8 being located between the upper flange 3 and the connecting plate 7, a concrete layer 6 being provided on the top of the connecting plate 7, and a transverse plate 10 being installed between the web 2 and the upper flange 3; a fastening assembly 9 is provided between the connecting plate 7 and the first composite floor slab 8, the fastening assembly 9 including fixing bolts 91 connected to the connecting plate 7, the first composite floor slab 8, and the upper flange 3, and nuts 92 screwed to the bottom of the fixing bolts 91, the nuts 92 contacting the bottom of the upper flange 3.

[0032] In use, firstly, the lower flange 1 is moved to a suitable position. Then, the first composite floor slab 8 is placed on top of the upper flange 3. Next, the connecting plate 7 is placed on top of the first composite floor slab 8. Then, the worker rotates the fixing bolt 91 so that the bottom of the fixing bolt 91 passes through the connecting plate 7, the first composite floor slab 8, and the upper flange 3. At the same time, the worker takes the nut 92 again, places the nut 92 on the bottom of the fixing bolt 91, and rotates the nut 92 so that the nut 92 is screwed onto the fixing bolt 91. The nut 92 then abuts against the bottom of the upper flange 3 to achieve the connection between the first composite floor slab 8, the connecting plate 7, and the upper flange 3, so as to facilitate the subsequent processing of the first composite floor slab 8. At the same time, the horizontal plate 10 can provide appropriate support for the upper flange 3 and the web plate 2 to prevent the web plate 2 and the upper flange 3 from shaking.

[0033] Reference Figure 3 The protective component 4 includes a receiving chamber 41 installed at the bottom of the upper flange 3 and a cavity opened inside the receiving chamber 41. One end of the receiving chamber 41 abuts against the web plate 2. Multiple through holes are opened at the bottom of the receiving chamber 41. A sealing component is provided inside the receiving chamber 41. The sealing component includes an opening slot opened at the end of the receiving chamber 41 away from the web plate 2 and a push plate 42 slidably installed on the opening slot. A baffle 44 is fixedly installed at the bottom of the push plate 42 and is located inside the cavity. An auxiliary pull plate 43 is fixedly installed at the end of the push plate 42 away from the receiving chamber 41. A limiting component is provided on the push plate 42. The limiting component includes a limiting plate 45 fixedly installed on the push plate 42 and is located inside the cavity. The limiting plate 45 is aligned with the opening slot.

[0034] When it is necessary to protect the surface of the web plate 2, firstly, oil is injected into the interior of the receiving chamber 41 to fill the cavity inside the receiving chamber 41. Then, the worker pulls the auxiliary pull plate 43, causing the auxiliary pull plate 43 and the push plate 42 to move simultaneously. The baffle 44 also moves with the push plate 42, pulling the baffle 44 open from the through hole, allowing the oil inside the receiving chamber 41 to flow down through the through hole until it flows into the flow channel. This achieves oil coverage of the surface of the web plate 2, preventing rust from forming on the web plate 2 during use, and appropriately extending the service life of the web plate 2. This allows the web plate 2 to better support the first composite floor slab 8, ensuring the safe use of the H-beam and reducing structural failures of the H-beam caused by rust, thereby improving overall safety.

[0035] Referring to the figure, a disassembly assembly 5 is provided on the horizontal plate 10. The disassembly assembly 5 includes a first mounting plate 51 fixedly installed on the top of the horizontal plate 10 and a second mounting plate 52 fixedly installed on the bottom of the horizontal plate 10. The first mounting plate 51 and the upper flange 3 are connected by a fixing screw 54, and the second mounting plate 52 and the web plate 2 are connected by a fixing screw 54. Auxiliary components are provided on both the first mounting plate 51 and the second mounting plate 52. The auxiliary components include a protective plate 53 fixedly installed on the first mounting plate 51 and the second mounting plate 52, and the fixing screw 54 penetrates the protective plate 53.

[0036] When it is necessary to remove the fastening assembly 9 from the web plate 2 and the upper flange 3, the operator first rotates the fixing screw 54 to unscrew it from the web plate 2 and the upper flange 3. Simultaneously, the first mounting plate 51 and the second mounting plate 52 are also removed from the web plate 2 and the upper flange 3. This allows for the installation of different numbers of fastening assemblies 9 depending on the environment, ensuring adequate support for the web plate 2 and the upper flange 3. This significantly improves the adaptability of the H-beam and makes moving the H-beam more convenient, facilitating its placement in a suitable position to support the first composite floor slab 8. This greatly enhances the practicality of the H-beam connecting components.
