Description

Technical Field

[0001] This utility model relates to the technical field of sidewalk construction mechanisms, and in particular to a prefabricated sidewalk slab structure. Background Technology

[0002] As a crucial component of urban slow-traffic systems, pedestrian walkways not only serve as vital passageways for citizens' daily travel but also as important windows showcasing a city's appearance and service levels. Functionally, they provide the basic necessities for pedestrian traffic, ensuring smooth and safe passage through scientifically planned widths and flow lines. Tactile paving, with its unique tactile guide bricks and continuous layout, offers thoughtful guidance for visually impaired individuals. Landscape signage, utilizing distinctive paving patterns, artistic tree pits, and reliefs and carvings rich in regional cultural elements, shapes urban aesthetics and cultural memory. Vehicle collision avoidance facilities, such as curbs and bollards, form physical barriers, effectively mitigating the risk of vehicle intrusion. Pipeline corridors, through prefabricated trenches or integrated utility tunnels, centrally house municipal pipelines such as electricity, communications, and water supply and drainage, facilitating future inspection and maintenance. A search revealed Chinese patent publication number CN221608578U, which discloses a lightweight, prefabricated, multi-functional pedestrian walkway system. This system includes prefabricated guardrail bases, prefabricated pedestrian walkway slabs, prefabricated curb stones, curb stone drainage pipes, and anchoring steel bars. Suitable for various types of bridges, this UHPC multi-functional pedestrian walkway system not only possesses the characteristics of conventional pedestrian walkways but also significantly improves construction speed and allows for rapid replacement due to its primary material being UHPC ultra-high performance concrete and all components being prefabricated. Furthermore, the overall system is lightweight, which benefits the bridge structure. Additionally, the internal channels of the prefabricated curb stones can serve as roadside drainage channels, the space under the pedestrian walkway slabs can provide a corridor for various bridge-mounted pipelines, and the surface of the prefabricated pedestrian walkway slabs can be patterned to meet the needs of tactile paving and regional landscape and cultural display. The aforementioned patent specification mentions "a lightweight, prefabricated, multi-functional pedestrian walkway system, including prefabricated guardrail base, prefabricated pedestrian walkway slabs, prefabricated curb stones, curb stone drainage pipes, and anchoring steel bars." Although the aforementioned mechanism can achieve the prefabrication and splicing of pedestrian walkway slabs, it still has obvious defects: on the one hand, the prefabricated components are numerous and interconnected, resulting in an overly complex mechanism design, which not only increases the difficulty of production and manufacturing but also raises the technical threshold and construction cost during the installation process. Utility Model Content

[0003] This utility model proposes a prefabricated and assembled sidewalk slab structure, which aims to improve upon the existing technology where some prefabricated and assembled sidewalk slab structures use complex interconnected mechanisms, resulting in complex mechanism design, increased production and installation difficulties, and higher costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated and assembled sidewalk slab structure, comprising a prefabricated sidewalk slab, drainage mechanisms fixedly connected to the left and right sides of the prefabricated sidewalk slab, splicing mechanisms fixedly connected to the left and right sides of the prefabricated sidewalk slab, a pipeline corridor fixedly connected inside the prefabricated sidewalk slab, and reinforcing bars fixedly connected inside the prefabricated sidewalk slab. The splicing mechanism includes multiple slotted splicing blocks. The far sides of two slotted splicing blocks are fixedly connected to the near sides of two precast sidewalk slabs. A drainage board is fixedly connected to the top of each slotted splicing block. An I-beam splicing block is slidably connected to the near sides of the two slotted splicing blocks. A shim is fixedly connected to the top of each I-beam splicing block. A water guide block is slidably connected to the interior of each I-beam splicing block and the interior of each slotted splicing block. A splicing groove is formed inside each slotted splicing block. Multiple screw positioning shafts are fixedly connected to the front and rear sides of each precast sidewalk slab. A locking plate is slidably connected to the outside of each screw positioning shaft.

[0005] The above-described prefabricated pedestrian walkway slab structure features a drainage system for timely flood control, a splicing mechanism for rapid and precise assembly with enhanced connection stability, a utility corridor for convenient installation and maintenance of municipal pipelines, and reinforced steel reinforcement for structural strength. The synergistic effect of these components improves construction efficiency, reduces maintenance costs, and combines practicality with durability, contributing to the creation of high-quality urban pedestrian spaces.

[0006] As a further description of the above technical solution: the drainage mechanism includes two roadside water troughs, the adjacent sides of the two roadside water troughs are fixedly connected to the front and rear sides of the precast sidewalk slab, and drainage blocks are provided on the distant sides of the two roadside water troughs, the bottom of the drainage blocks corresponding to the top of the sewer opening.

[0007] The above solution involves placing two roadside water channels on the front and rear sides of the precast sidewalk slab, precisely connecting them to the sewer inlets with drainage blocks to form an efficient drainage path. This allows for the rapid collection and discharge of rainwater, preventing road surface flooding, pedestrian slips, and damage to facilities from soaking, ensuring a dry and safe sidewalk. Simultaneously, it reduces water erosion of the slab structure, extends its service life, and improves user experience and maintenance convenience.

[0008] As a further description of the above technical solution: the pipeline corridor includes a pipeline block, the outside of which is fixedly connected to the inside of the precast sidewalk slab, a cable tray top plate is fixedly connected to the top of the pipeline block, the top of the cable tray top plate is fixedly connected to the bottom of the precast sidewalk slab, and a cable tray is provided inside the pipeline block.

[0009] The above-described pipeline corridor integrates pipeline blocks into prefabricated sidewalk slabs, supported by a slab roof with a rationally designed internal cable tray. This effectively accommodates municipal pipelines such as power and communication lines, achieving a compact layout and facilitating future inspection and maintenance. Simultaneously, it prevents pipelines from being exposed and damaged, enhancing their safety and lifespan, while also saving underground space and improving the overall utilization efficiency of sidewalks.

[0010] As a further description of the above technical solution: drainage holes are provided inside the drainage plate and inside the grooved splicing block, and through holes are provided inside the I-beam splicing block. The upper and lower sides of the through holes correspond to the outside of the drainage holes, and the top of the water guide block is located at the bottom of the drainage holes.

[0011] The above solution involves drainage boards and grooved interlocking blocks with drainage holes, and I-beam interlocking blocks with corresponding through holes, forming a continuous drainage channel in conjunction with bottom water-guiding blocks. This design can quickly drain water accumulated at the joints, preventing water seepage from damaging the structure, keeping the interlocking parts of the sidewalk dry, effectively improving the stability and durability of the joints, reducing maintenance costs, and optimizing the user experience.

[0012] As a further description of the above technical solution: there are gaps between the left and right sides of the I-shaped splicing block and the left and right sides of the splicing groove; the bottom of the drainage board and the top of the grooved splicing block form a cavity; and there are gaps between the left and right sides of the grooved splicing block and the inner wall of the cavity.

[0013] The above solution involves pre-reserved gaps between the I-beam interlocking blocks and the interlocking grooves, and between the grooved interlocking blocks and the cavity. The drainage board and the grooved interlocking blocks form the cavity. This design facilitates rapid rainwater flow and drainage, preventing water accumulation at the joints. Simultaneously, the gaps and cavities provide the mechanism with a certain buffer deformation space, which can alleviate external stress and enhance the stability and durability of the assembled sidewalk slabs.

[0014] As a further description of the above technical solution: the locking plate has two adjustment grooves inside, and the screw positioning shaft is externally slidably connected to the inside of the adjustment grooves. The width of the two adjustment grooves is greater than the width of the screw positioning shaft.

[0015] The above solution involves adjusting the groove width within the locking plate to be greater than that of the screw positioning shaft, allowing the screw positioning shaft to slide within the groove. This design allows for a certain degree of positional deviation adjustment space during the splicing of prefabricated sidewalk slabs, reducing installation accuracy requirements and accelerating construction progress. At the same time, it can effectively adapt to thermal expansion and contraction or foundation settlement, preventing damage to the mechanism due to stress concentration and improving the overall connection stability and durability.

[0016] As a further description of the above technical solution: the roadside water trough has a disassembly hole inside, the inside of the disassembly hole corresponds to the front and rear sides of the I-beam splicing block, and the inside of the drainage block corresponds to the outside of the disassembly hole.

[0017] The above solution involves setting up disassembly holes in the roadside water channels to correspond to the I-beam splicing blocks. The interior of the drainage block is connected to the disassembly holes. This design facilitates operation of the I-beam splicing blocks from the outside through the disassembly holes. When inspecting or replacing sidewalk slabs, there is no need for large-scale disassembly of the mechanism, reducing construction work and time costs, improving maintenance efficiency, ensuring unobstructed drainage, and enhancing the overall maintenance convenience and durability of the sidewalk mechanism.

[0018] As a further description of the above technical solution: the top of the prefabricated sidewalk slab is designed to be high in the middle and low on both sides, and multiple water guide grooves are opened on the top of the prefabricated sidewalk slab.

[0019] The above-mentioned solution involves a prefabricated sidewalk slab with a higher center and lower sides, and multiple drainage channels. This allows rainwater to flow smoothly to the drainage mechanisms on both sides, accelerating surface runoff and effectively preventing water accumulation on the road. This design not only improves pedestrian safety and reduces the risk of slipping, but also reduces the erosion of the slab by accumulated water, extends the service life of the sidewalk, and ensures a good condition for the urban slow-traffic environment.

[0020] This utility model has the following beneficial effects: When laying prefabricated sidewalk slabs, the bottom of the slabs contacts the ground, and the grooved and I-beam splicing blocks fixed to both sides of the slabs are connected. Because the grooved and I-beam splicing blocks use a sliding connection, the efficiency of subsequent replacement of the prefabricated sidewalk slabs is improved. Drainage holes inside the drainage boards and I-beam splicing blocks facilitate drainage of the prefabricated sidewalk slabs. Overall, this mechanism, through functional integration design, organically combines convenient maintenance with efficient drainage, providing a systematic solution for the long-term use, low-cost maintenance, and improved safety performance of sidewalks, meeting the needs of refined urban infrastructure management.

[0021] In this invention, when draining precast sidewalk slabs, water flowing into the grooved splicing block through the drainage outlets inside the drainage board and the I-beam splicing block is guided by the water guide block to the drainage mechanism. With the help of the roadside water trough and the drainage block, it flows into the sewer. However, because the water guide block is made of rubber, it prevents water from entering the bottom of the precast sidewalk slab, thus preventing corrosion of the bottom of the precast sidewalk slab and affecting its use.

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.

[0025] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a prefabricated and assembled sidewalk structure, including a prefabricated sidewalk slab 1, which is the core of the structure. The prefabricated sidewalk slab 1 is designed with a higher center and lower sides to effectively guide rainwater flow to both sides. Multiple water-guiding channels are provided on its surface to quickly guide water flow, effectively reducing water accumulation and improving sidewalk safety. Drainage mechanisms 3 and splicing mechanisms 2 are fixedly connected to the left and right sides of the prefabricated sidewalk slab 1. A pipeline corridor 4 and reinforcing bars 5 are fixedly connected inside the prefabricated sidewalk slab 1. The top of the prefabricated sidewalk slab 1 has a design that is higher in the middle and lower on both sides, and multiple water-guiding channels are provided on the top of the prefabricated sidewalk slab 1. Specifically, the precast sidewalk slab 1 serves as the core, with a top that is high in the middle and low on both sides, and multiple drainage channels are provided. During rainfall, rainwater flows from the middle to both sides along the drainage channels under the action of gravity. The drainage mechanisms 3 fixed on the left and right sides receive the rainwater collected from the drainage channels and discharge it. The pipeline corridor 4 inside the precast sidewalk slab 1 can be used to lay various pipelines. The steel bars 5 fixedly connected inside enhance the structural strength of the precast sidewalk slab 1. At the same time, the precast sidewalk slab 1 can be spliced ​​with other slabs through the splicing mechanisms 2 on the left and right sides to form a complete sidewalk slab structure. The splicing mechanism 2 includes multiple grooved splicing blocks 24. The joint point where the grooved splicing block 24 is fixed to the precast sidewalk slab 1 has a drainage plate 22, forming a cavity to enhance drainage. The far sides of two grooved splicing blocks 24 are fixedly connected to the near sides of two precast sidewalk slabs 1. The top of the grooved splicing block 24 is fixedly connected to the drainage plate 22. An I-beam splicing block 21 is slidably connected to the near sides of two grooved splicing blocks 24. The I-beam splicing block 21 is slidably connected between the grooved splicing blocks 24. The reserved gap design allows for more flexible splicing and can be adjusted according to subsequent needs. Gaps exist between the left and right sides of the I-beam splicing block 21 and the near sides of the splicing groove 26. The drainage plate 22 and the grooved splicing block 24 form a cavity. There is a gap between 24 and the cavity. The top of the I-beam splicing block 21 is fixedly connected to the shim block 23. The I-beam splicing block 21 and the grooved splicing block 24 are slidably connected to the water guide block 25. The grooved splicing block 24 has a splicing groove 26 inside. The front and rear sides of the precast sidewalk slab 1 are fixedly connected to multiple screw positioning shafts 28. The screw positioning shafts 28 are slidably connected to the outside of the screw positioning shafts 28. The drainage plate 22 and the grooved splicing block 24 are both provided with drainage holes. The I-beam splicing block 21 has a through hole inside, which corresponds to the drainage hole. The water guide block 25 is located at the bottom of the drainage hole. The locking plate 27 has two adjustment grooves inside. The screw positioning shafts 28 are slidably connected to the inside of the adjustment grooves. The width of the two adjustment grooves is greater than the width of the screw positioning shafts 28. Specifically, grooved splicing blocks 24 are fixed to the adjacent sides of two precast sidewalk slabs 1, and drainage boards 22 are fixed to the top of the grooved splicing blocks 24, forming a cavity. I-beam splicing blocks 21 are slidably connected to the adjacent sides of the two grooved splicing blocks 24, with gaps on their left and right sides near the splicing grooves 26. A shim 23 is fixed to the top. The grooved splicing blocks 24 have splicing grooves 26 inside. Water guide blocks 25 are slidably connected inside the I-beam splicing blocks 21 and the grooved splicing blocks 24. The drainage boards 22, grooved splicing blocks 24, and I-beam splicing blocks 21 are respectively... Drainage holes and through holes are provided and correspond to each other. Water guide blocks 25 are located at the bottom of the drainage holes to assist in water guidance. Locking plates 27 are externally slidably connected to the screw positioning shafts 28 on the front and rear sides of the prefabricated sidewalk slab 1. The width of the two adjustment grooves inside the locking plate 27 is greater than the width of the screw positioning shafts 28. During splicing, the I-shaped splicing block 21 can be flexibly slidably adjusted in position. Rainwater flows from the drainage holes of the drainage plate 22 and the grooved splicing block 24 through the through holes and is guided out through the water guide blocks 25. At the same time, the locking plate 27 can be slidably adjusted on the screw positioning shafts 28 to assist in completing the splicing of the sidewalk slab.

[0026] Reference Figure 1 , Figure 3 , Figure 5 The drainage mechanism 3 includes two roadside water channels 31, which are fixedly connected to the front and rear sides of the precast sidewalk slab 1 and cooperate with the sewer inlet to effectively drain surface water into the sewer. The two roadside water channels 31 are fixedly connected to the front and rear sides of the precast sidewalk slab 1. A drainage block 32 is provided on the far side of the two roadside water channels 31. The design of the drainage block 32 allows water to flow smoothly into the sewer, avoids rainwater stagnation on the road, and reduces the safety hazards caused by the slippery road surface. The bottom of the drainage block 32 corresponds to the sewer inlet. The roadside water channel 31 has a disassembly hole inside, which facilitates the subsequent inspection and maintenance of the I-beam splicing block 21. The disassembly hole corresponds to the I-beam splicing block 21, and the interior of the drainage block 32 corresponds to the disassembly hole. Specifically, when the drainage mechanism 3 is working, the roadside water channels 31 on both sides of the precast sidewalk slab 1 receive rainwater discharged from the surface of the precast sidewalk slab 1 and the splicing mechanism 2. After the rainwater gathers in the roadside water channels 31, it flows through the drainage block 32 opened on the opposite side. Since the bottom of the drainage block 32 corresponds to the sewer opening, the rainwater can flow smoothly into the sewer. At the same time, the disassembly holes opened inside the roadside water channels 31 correspond to the disassembly holes inside the I-beam splicing block 21 and the drainage block 32. When it is necessary to inspect and maintain the I-beam splicing block 21, the relevant operations can be carried out through the disassembly holes. The utility corridor 4 includes utility blocks 42. The utility corridor 4 is designed to accommodate various utility lines and is designed as a hollow structure to meet the laying requirements of facilities such as electrical wires and water pipes. The utility blocks 42 are fixedly connected to the inside of the precast sidewalk slab 1. The top of the utility blocks 42 is fixedly connected to a cable tray top plate 41. The cable tray top plate 41 ensures that the corridor is covered and provides appropriate protection to prevent external factors from affecting the utility lines. The top of the cable tray top plate 41 is fixedly connected to the bottom of the precast sidewalk slab 1. The utility blocks 42 have cable trays inside. The cable trays inside the utility blocks 42 help to organize and place different types of utility lines, thereby maintaining the cleanliness and aesthetics of the sidewalk. Specifically, the pipeline block 42 is fixed inside the precast sidewalk slab 1. The cable tray inside is used to organize and install various pipelines such as electric wires and water pipes, providing space for pipeline laying. The top plate 41 of the cable tray is fixed to the top of the pipeline block 42, covering and enclosing the pipeline corridor 4. At the same time, its top is connected to the bottom of the precast sidewalk slab 1, providing protection for the pipelines. After laying, the pipelines are enclosed in the pipeline corridor 4 and arranged in an orderly manner in the internal space of the precast sidewalk slab 1.

[0027] Working principle: When splicing prefabricated sidewalk slabs 1, the bottom of the prefabricated sidewalk slab 1 is brought into contact with the ground. Then, the prefabricated sidewalk slab 1 is pushed closer to the prefabricated sidewalk slab 1 to be spliced. During this process, the grooved splicing blocks 24 and water guide blocks 25 fixed on the left and right sides of the prefabricated sidewalk slab 1 correspond to the spliced ​​prefabricated sidewalk slab 1. Then, the shim block 23 and the I-beam splicing block 21 are placed in the splicing groove 26 opened in the grooved splicing block 24. The shim block 23 restricts the I-beam splicing block 21 and the grooved splicing block 24. The shim block 23 prevents the height difference between the drainage board 22 and the I-beam splicing block 21 from affecting the use of the prefabricated sidewalk slab 1. Then, the locking plate 27 is aligned with the screw positioning shaft 28 fixed on the front and rear sides of the prefabricated sidewalk slab 1. Then, the screws and screw positioning shaft 28 are connected to restrict the I-beam splicing block 21 and prevent the I-beam splicing block 21 from sliding during subsequent use, thus affecting the use of the prefabricated sidewalk slab 1. Multiple drainage holes are provided inside the drainage board 22, the grooved splicing block 24, and the I-beam splicing block 21. These holes work in conjunction with the water guide channel on the top of the precast sidewalk slab 1 to drain water. Water flowing into the adjacent side of the two grooved splicing blocks 24 through the drainage holes is guided by the water guide block 25 and flows into the interior of the roadside water channel 31. The water then flows into the roadside water channel 31 through the drainage channel inside the roadside water channel 31 and is discharged into the sewer with the help of the roadside water channel 31. When the precast sidewalk slab 1 is used, the pipeline block 42 located inside the precast sidewalk slab 1 serves as a wiring channel. Together with the top plate 41 of the wire trough inside the precast sidewalk slab 1, it supports the internal space of the pipeline block 42, thereby ensuring the stability of the wiring channel and improving the practicality of the precast sidewalk slab 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
