Description

TECHNICAL FIELD

[0001] The present application relates to the field of sidewalk slabs, in particular to a prefabricated assembly type sidewalk integrated slab and a manufacturing system thereof. BACKGROUND

[0002] In modern urban road construction, the sidewalk system needs to consider traffic safety, barrier-free facilities and drainage function. Traditional construction adopts step-by-step paving of pavement slabs, blind brick and kerb stone, which has problems such as complex process, long construction period, inaccurate blind connection, and displacement of kerb stone.

[0003] Foreign research status: The prefabricated concrete pavement slab technology in developed countries such as Europe, America and Japan is relatively mature, and has been widely used in municipal road engineering, but its technical route focuses on basic traffic function. The blind system mostly uses post-pasting resin material or independent prefabricated brick, which is designed separately from the pavement slab. This modular fragmentation leads to easy wear and tear of the blind, uneven connection with the pavement, and poor durability of the resin material (common service life <5 years), which is difficult to meet the high load use scenario. Domestic research status: Significant progress has been made in single prefabricated technology in China, such as standardization of production of permeable bricks and prefabricated kerb stones. However, there are obvious shortcomings in the field of multi-functional integration: technical level: the blind mainly relies on on-site paving of ceramic bricks or polymer base materials, with insufficient precision control (the survey by the Ministry of Housing and Urban-Rural Development shows that the qualified rate is only 68.5%), and lacks structural synergy with pavement slabs; standard level: the current "Barrier-free Design Specification" (GB50763-2012) does not cover the technical standards of integrated prefabricated components; research level: university and enterprise research focuses on single material performance optimization (such as recycled aggregate application), and the research on systematic prefabricated design of "pavement-blind-kerb" is almost blank.

[0004] Research status analysis: There are common bottlenecks in the current global sidewalk construction field: Functional fragmentation: blind, kerb and pavement are constructed in steps, with poor system synergy; Insufficient precision: the traditional on-site construction of blind has a convexity precision error of ≥2mm (exceeding the national standard allowable value).

[0005] In view of this, we propose a prefabricated assembly type sidewalk integrated slab and a manufacturing system thereof. SUMMARY

[0006] The present application relates to the field of sidewalk slabs, in particular to a prefabricated assembly type sidewalk integrated slab and a manufacturing system thereof. The prefabricated integrated sidewalk panel includes a unit panel made of concrete. The unit panel is composed of a curb protrusion structure, a flat area, a tactile paving area and a drainage area. The drainage area is integrated with a water-retaining curb at the end. The two sides of the unit panel are fitted with a matching close-fitting structure. The tactile paving area is integrated with a tactile paving protrusion. The drainage area is provided with drainage holes.

[0007] A manufacturing system for producing prefabricated integrated pedestrian walkway panels includes a mold for forming the prefabricated integrated pedestrian walkway panels, a belt conveyor and a gantry frame mounted on a base, the belt conveyor having multiple slots, the mold being mounted on the slots, and the belt conveyor being located below the gantry frame.

[0008] Preferably, the mold includes a bottom mold and an upper mold, which are fixedly connected by a snap-fit ​​assembly. After the bottom mold and the upper mold are closed, the internal cavity structure is consistent with the prefabricated assembled pedestrian walkway integrated panel. The upper mold is provided with a pouring gate, and the bottom of the bottom mold is fixed with a locking block, which is locked in a slot.

[0009] Preferably, a cylinder is fixed on the gantry frame, and a hanger is fixed to the piston rod end of the cylinder, and a casting pipe and a vibrator are fixed on the hanger.

[0010] Preferably, a pump is fixed on the base, and the pump is connected to the concrete tank and the pouring pipe respectively through the delivery pipe, and the outlet of the pouring pipe is connected to the pouring port.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention integrates four core functions—road surface load-bearing, tactile paving guidance, curb stones, and drainage—into a single precast concrete component, fundamentally solving problems such as poor system coordination, easy misalignment of tactile paving, curb stone settlement, and poor drainage caused by traditional step-by-step construction.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1 to 2 This invention provides a technical solution: a prefabricated integrated sidewalk panel, comprising a unit panel 1 made of concrete. The unit panel 1 is integrally composed of a curb protrusion structure 2, a flat area 3, a tactile paving area 4, and a drainage area 5. A water-retaining curb is integrally provided at the end of the drainage area 5. Matching close-fitting structures 8 are provided at the splicing parts on both sides of the unit panel 1. A blind groove protrusion 6 is integrally fixed on the tactile paving area 4. Drainage holes 7 are provided in the drainage area 5. The close-fitting structure 8 can be a tenon and mortise connection structure or a tongue and groove connection structure. When two unit panels 1 are spliced ​​together, a rubber waterstop is installed between the close-fitting structures 8 to maintain the tight positioning connection and waterproof sealing between the two unit panels 1.

[0016] Advantages of this type of prefabricated integrated pedestrian walkway panel: Improve the standardization of barrier-free facilities: integrate the tactile paving pattern with the pavement panel for prefabrication to eliminate the problems of displacement and wear of traditional tactile paving bricks.

[0017] Promote green construction: reduce on-site cutting and pouring processes, and reduce dust, noise pollution and construction waste by more than 80%.

[0018] Cost reduction and efficiency improvement: shorten the construction period by 40%, reduce reliance on manual labor, and reduce overall costs by 15%.

[0019] This addresses the problem of independent curbstone installations leading to settlement and subsequent sidewalk drainage failure. Functional integration: The world's first project to integrate four core functions—road surface load-bearing, tactile paving guidance, curb stones, and drainage—into a single precast concrete component, fundamentally solving problems such as poor system coordination, easy misalignment of tactile paving, curb stone settlement, and poor drainage caused by traditional step-by-step construction.

[0020] This type of prefabricated assembled pedestrian walkway integrated panel can form a prefabricated component system covering a variety of standardized panel types such as straight panels, corner panels, and ramp connection panels, which is suitable for 90% of municipal pedestrian walkway scenarios.

[0021] Please see Figures 3 to 4 The present invention provides a technical solution: a manufacturing system for manufacturing prefabricated assembled pedestrian walkway panels, including a mold 12 for forming the prefabricated assembled pedestrian walkway panels, a belt conveyor 10 and a gantry frame 13 set on a base 9, wherein the belt conveyor 10 is provided with a plurality of slots 11, the mold 12 is set on the slots 11, and the belt conveyor 10 is located below the gantry frame 13.

[0022] In this embodiment, the mold 12 includes a bottom mold 20 and an upper mold 22. The bottom mold 20 and the upper mold 22 are fixedly connected by a snap-fit ​​assembly 23. After the bottom mold 20 and the upper mold 22 are closed, the internal cavity structure is consistent with the prefabricated assembled sidewalk panel. The upper mold 22 is provided with a pouring port 24. The bottom of the bottom mold 20 is fixed with a locking block 21, and the locking block 21 is locked in the locking groove 11. The mold 12 is produced using high-precision steel molds to ensure that the tactile paving protrusion accuracy is ±0.5mm. Steam curing (65℃ constant temperature for 8 hours) improves early strength.

[0023] In this embodiment, a cylinder 14 is fixed on the gantry frame 13, and a hanger 15 is fixed to the piston rod end of the cylinder 14. A casting pipe 18 and a vibrator 19 are fixed on the hanger 15.

[0024] In this embodiment, a pump 16 is fixed on the base 9. The pump 16 is connected to the concrete tank and the pouring pipe 18 through the delivery pipe 17. The outlet of the pouring pipe 18 is connected to the pouring port 24.

[0025] Working principle and advantages of this invention: The manufacturing system for this type of prefabricated assembled pedestrian walkway panel operates as follows: like Figure 3 and Figure 4As shown, the upper mold 22 and the bottom mold 20 are fixed by the snap-fit ​​assembly 23. Then, the snap-fit ​​block 21 on the mold 12 is snapped into the slot 11. The belt conveyor 10 is started to transport the empty mold to the bottom of the gantry 13, so that the pouring gate 24 is located directly below the pouring pipe 18. The cylinder 14 is started to work, so that the cylinder 14 drives the hanger 15 to move down, thereby causing the hanger 15 to drive the pouring pipe 18 and the vibrator 19 to move down. When the pouring pipe 18 is connected to the pouring gate 24, the cylinder 14 is stopped. At this time, the vibrator 19 presses on the upper mold 22. Then, the pump 16 and the vibrator 19 are started. The pump 16 delivers the material through the conveying pipe 17. Concrete is delivered to the pouring pipe 18 and enters the mold cavity through the pouring port 24. The vibration force generated by the vibrator 19 causes the concrete to spread and distribute evenly in the mold cavity. Then, the vibrator 19 and the pump 16 are turned off, and the cylinder 14 is started to drive the hanger 15 to move up and reset, so that the pouring pipe 18 is separated from the pouring port 24. The completed mold 12 is moved out by the belt conveyor 10, and the next empty mold 12 is moved to the bottom of the gantry 13. The completed mold 12 is removed from the slot 11. After the unit plate 1 has solidified, the buckle assembly 23 is opened, so that the upper mold 22 is removed, and the unit plate 1 can be demolded.

[0026] The entire system quickly and efficiently pours and transfers the mold 12, improving production efficiency.
