Description

Technical Field

[0001] This application relates to the technical field of fixed buildings, and in particular to the construction of expansion joints between industrial warehouses and forklift access corridors. Background Technology

[0002] In the field of industrial warehousing buildings, steel-structured corridors are often erected between two independent warehouses to meet the needs of production processes. These corridors traditionally function primarily to facilitate the passage of process equipment pipelines, typically without the need for personnel or heavy vehicle traffic. Therefore, the floor expansion joints at the connection between the corridor and the main warehouse structure are relatively simple in construction, often using thin cover plates to provide basic shelter and pedestrian access. This conventional construction does not consider the impact of dynamic heavy loads and long-term crushing; its design focuses on accommodating static displacement differences between structures, such as settlement and thermal expansion and contraction, rather than structural load-bearing capacity. This makes existing technologies effective for simple connection and sealing needs, but their application scenarios are significantly limited, unable to meet more demanding passage requirements.

[0003] However, with the development of modern logistics and warehousing processes, a new demand has emerged: forklifts need to be fully loaded and pass directly through connecting corridors to transfer materials between different warehouses. This situation poses a severe challenge to the construction of expansion joints between the connecting corridors and warehouses. First, ordinary thin cover plates and their base layers cannot withstand the huge concentrated loads and repeated impacts of forklifts and their fully loaded goods, easily leading to deformation and damage of the cover plates, posing safety hazards. Second, the external enclosure structure of industrial warehouses typically uses lightweight purlins and profiled steel sheet walls, which themselves lack load-bearing capacity and cannot serve as the load-bearing foundation for forklift passage. Therefore, a new type of expansion joint structure is urgently needed. It must not only effectively adapt to structural deformation but also possess sufficient structural strength to support forklift passage and solve the problem of stress transmission at lightweight exterior walls. This is precisely the core technical problem that this patent application aims to solve. Utility Model Content

[0004] To improve practicality, this application provides an expansion joint structure between industrial storage warehouses and forklift access corridors.

[0005] The expansion joint structure between the industrial storage warehouse and the forklift passageway provided in this application adopts the following technical solution:

[0006] The expansion joint structure between the industrial storage warehouse and the forklift passageway includes the warehouse and the passageway located on the outer right side of the warehouse. A steel plate layer structure is provided between the opposite surfaces of the warehouse and the passageway. A bottom shock-absorbing pad is provided on the lower outer surface of the steel plate layer structure, and a hard rubber shock-absorbing pad structure is provided on the upper outer surface of the steel plate layer structure. An edge-protecting angle steel is fixedly connected to the upper outer surfaces of both the warehouse and the passageway.

[0007] As a preferred embodiment of this application, expansion joints are provided on the upper outer surfaces of both the warehouse and the connecting corridor.

[0008] As a preferred embodiment of this application, the bottom shock-absorbing pad includes a wear-resistant layer, a buffer layer is fixedly connected to the lower outer surface of the wear-resistant layer, and the upper outer surface of the wear-resistant layer is in contact with the lower outer surface of the steel plate layer structure.

[0009] As a preferred embodiment of this application, the steel plate layer structure includes a steel plate foundation, a strip-shaped mounting block is provided on the upper outer surface of the steel plate foundation, a circular positioning protrusion is fixedly connected to the upper outer surface of the strip-shaped mounting block, the rigid rubber damping pad structure includes a rigid rubber damping pad base layer, an antibacterial and anti-corrosion layer is fixedly connected to the lower outer surface of the rigid rubber damping pad base layer, and fixing screws are interspersed on the upper outer surface of the strip-shaped mounting block.

[0010] As a preferred embodiment of this application, the number of the bottom shock-absorbing pads is two, and the two bottom shock-absorbing pads are respectively disposed on the upper inner surface of the warehouse and the connecting corridor.

[0011] As a preferred embodiment of this application, the upper outer surface of the steel plate foundation is provided with a first mounting groove adapted to the strip mounting block, and the steel plate foundation is movably connected to the strip mounting block through the first mounting groove.

[0012] As a preferred embodiment of this application, the upper outer surface of the steel plate foundation has a first threaded hole adapted to the fixing screw, and the steel plate foundation is threadedly connected to the fixing screw through the first threaded hole.

[0013] As a preferred embodiment of this application, the lower outer surface of the rigid rubber damping pad base layer is provided with a circular positioning hole that matches the circular positioning protrusion, and the rigid rubber damping pad base layer is movably connected to the circular positioning protrusion through the circular positioning hole.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] This application provides a composite expansion joint structure specifically designed for heavy-duty forklift passage, integrating high load-bearing capacity, impact resistance, and deformation adaptability. By installing a thick steel plate layer structure at the expansion joint between the warehouse and the connecting corridor, and innovatively configuring rigid rubber shock-absorbing pads on its upper and lower surfaces and a bottom shock-absorbing pad, it successfully solves the technical bottleneck of traditional thin cover plates being unable to withstand the dynamic loads of forklifts. The steel plate layer structure, as the main load-bearing component, evenly distributes the huge concentrated load and impact force generated by forklift wheels to the bottom shock-absorbing pad below and the concrete foundation on both sides, avoiding stress concentration that could damage the main structure. The upper layer of rigid rubber shock-absorbing pads directly bears the pressure and impact of forklift tires. Its excellent elasticity and wear resistance not only effectively buffer the dynamic effect and reduce noise, but also provide a smooth and non-slip transition surface for forklift passage, ensuring operational safety and comfort. This multi-layered design that combines rigidity and flexibility allows the structure to maintain its structural integrity and functional stability while allowing necessary settlement or thermal expansion and contraction displacement between the warehouse and the corridor. It transforms the expansion joint from a "weak link" in the structure into a solid and reliable permanent passage, greatly expanding the functional uses of industrial corridors.

[0016] This application, through ingenious detailed design, comprehensively addresses multiple issues related to stress, durability, and maintainability. Firstly, the protective angle steel installed on both sides of the expansion joint not only provides robust protection for the concrete edges, preventing forklift tires from eroding and damaging them, but also works in conjunction with the joint sealant to ensure the sealing and durability of the expansion joint, effectively preventing the intrusion of debris and rainwater. Secondly, the bottom shock-absorbing pad employs a composite structure of a wear-resistant layer and a buffer layer, which reduces hard friction and vibration transmission between the steel plate and the concrete foundation, while also extending the service life of the entire shock-absorbing system.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] See Figure 1-3 The expansion joint structure between the industrial storage warehouse and the forklift passageway includes the warehouse 1 and the passageway 2 located on the outer right side of the warehouse 1. A steel plate layer structure 3 is provided between the opposite surfaces of the warehouse 1 and the passageway 2. A bottom shock-absorbing pad 4 is provided on the lower outer surface of the steel plate layer structure 3, and a hard rubber shock-absorbing pad structure 6 is provided on the upper outer surface of the steel plate layer structure 3. An edge protection angle steel 5 is fixedly connected to the upper outer surfaces of the warehouse 1 and the passageway 2.

[0023] Expansion joints are provided on the upper outer surfaces of both warehouse 1 and connecting corridor 2. The bottom shock-absorbing pad 4 includes a wear-resistant layer 401. A buffer layer 402 is fixedly connected to the lower outer surface of the wear-resistant layer 401. The upper outer surface of the wear-resistant layer 401 is in contact with the lower outer surface of the steel plate layer structure 3. The steel plate layer structure 3 includes a steel plate foundation 301. A strip-shaped mounting block 304 is provided on the upper outer surface of the steel plate foundation 301. A circular positioning protrusion 302 is fixedly connected to the upper outer surface of the strip-shaped mounting block 304. The hard rubber shock-absorbing pad structure 6 includes a hard rubber shock-absorbing pad base layer 601. An antibacterial and anti-corrosion layer 602 is fixedly connected to the lower outer surface of the hard rubber shock-absorbing pad base layer 601. Fixing screws 303 are interspersed on the upper outer surface of the strip-shaped mounting block 304.

[0024] The system effectively disperses, buffers, and absorbs the enormous dynamic load generated by forklift passage, while perfectly adapting to deformation and displacement between building structures. When a forklift fully loaded with goods passes through the joint between corridor 2 and warehouse 1, its weight first acts on the uppermost rigid rubber shock-absorbing pad structure 6. The rigid rubber shock-absorbing pad base layer 601, utilizing its high strength and elasticity, directly bears the instantaneous impact of the tires and the continuous rolling load, initially dispersing the concentrated stress. The underlying antibacterial and anti-corrosion layer 602 ensures that the structure can resist corrosion and microbial erosion in industrial environments for a long time, maintaining stable performance. The impact energy is significantly weakened after passing through the rigid rubber shock-absorbing pad structure 6, and then the load is transferred to the steel plate layer structure 3, which serves as the main load-bearing skeleton. The thick steel plate base 301, with its excellent structural rigidity and strength, transforms the pressure from above into a uniformly distributed load, acting like a sturdy "bridge" spanning the expansion joint, ensuring that it will not bend or break even under heavy loads, thus guaranteeing the continuity and stability of the passageway.

[0025] There are two bottom shock-absorbing pads 4. The two bottom shock-absorbing pads 4 are respectively set on the upper inner surface of warehouse 1 and connecting corridor 2. The upper outer surface of steel plate foundation 301 is provided with a first mounting groove that matches the strip mounting block 304. Steel plate foundation 301 is movably connected to strip mounting block 304 through the first mounting groove. The upper outer surface of steel plate foundation 301 is provided with a first threaded hole that matches the fixing screw 303. Steel plate foundation 301 is threadedly connected to fixing screw 303 through the first threaded hole.

[0026] The lower outer surface of the rigid rubber damping pad base layer 601 is provided with a circular positioning hole that matches the circular positioning protrusion 302. The rigid rubber damping pad base layer 601 is movably connected to the circular positioning protrusion 302 through the circular positioning hole.

[0027] The steel plate layer structure 3 ultimately transfers the load to the bottom shock-absorbing pad 4. The buffer layer 402 of this bottom shock-absorbing pad 4 further compresses, providing secondary shock absorption and completely eliminating any potential hard collisions and vibration transmission between the steel plate foundation 301 and the concrete foundations of warehouse 1 and connecting corridor 2; while its wear-resistant layer 401 effectively reduces frictional wear with the steel plate. Simultaneously, the entire structure is constrained by the edge protection angle steel 5 on both sides, protecting the concrete from erosion and forming a seal with the sealant. More ingeniously, its modular connection principle achieves a unity of function and maintenance: the strip mounting block 304 is initially positioned with the steel plate foundation 301 through the first mounting groove, and then tightened by the fixing screw 303 screwed into the first threaded hole, forming a stable and reliable connection. At the same time, the rigid rubber shock-absorbing pad base layer 601 achieves rapid alignment and displacement-resistant fixation through the precise engagement of its bottom circular positioning hole with the circular positioning protrusion 302 on the strip mounting block 304. This design allows the rigid rubber damping pad structure 6, which bears the main wear, to be disassembled and replaced independently and easily without damaging the main load-bearing structure below, greatly improving maintenance efficiency and reducing the cost over the entire life cycle.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
