[0001] This utility model relates to the field of prefabricated concrete road slab technology, and in particular to a prefabricated reinforced concrete temporary road intersection. Background Technology

[0002] In scenarios such as building construction, municipal road diversion, and temporary traffic diversion, it is often necessary to set up temporary intersection structures with features such as rapid paving, reusability, and structural stability to ensure the smooth passage of people and engineering vehicles. In recent years, prefabricated reinforced concrete pavement panels have been gradually introduced into the construction of temporary roads. With their features of factory prefabrication and rapid on-site assembly, they have obvious advantages in shortening the construction period and improving the paving quality.

[0003] The existing connection methods between most precast slabs are relatively simple, relying only on simple tenon and groove or pre-embedded steel bars for connection. When faced with frequent vehicle traffic, slight foundation settlement or external impact, misalignment, loosening or cracking can easily occur, affecting the overall stability of the road. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the existing connection methods between most precast slabs are relatively simple, relying only on simple tenon and groove joints or pre-embedded steel bars. These methods are prone to misalignment, loosening, or cracking under frequent vehicle traffic, slight foundation settlement, or external impacts, affecting the overall stability of the road. To address this, a precast assembled reinforced concrete temporary roadway is provided, comprising: a road slab with multiple lifting holes on its surface; an assembly mechanism for quickly assembling multiple road slabs, the assembly mechanism being located on the outer side of the road slab; wherein the assembly mechanism includes a structural frame fixedly installed at the bottom of the road slab, the outer side of the structural frame having mounting components for connecting adjacent road slabs, and the outer side of the road slab having drainage components.

A positioning block is fixedly installed inside the fixing block, and a positioning groove is provided at the bottom of the connecting block. The positioning groove is adapted to the shape of the connecting block.

[0006] Two connecting rods are fixedly installed on the other side of the structural frame, and sealing tubes are fixedly installed on the side of the two connecting blocks near the structural frame. The two sealing tubes are slidably connected to the two connecting rods respectively.

[0007] A spring is fixedly installed inside the sealing tube, and the other end of the spring is fixedly connected to one end of the connecting rod.

[0008] A steel mesh is fixedly installed inside the structural frame, and a plurality of reinforcing ribs are fixedly installed outside the structural frame. The tops of the plurality of reinforcing ribs are fixedly connected to the bottom of the road plate.

[0009] The structural frame is arranged in a double-square shape, and the steel mesh is located inside the structural frame.

[0010] The drainage component includes a drainage groove opened at the top edge of the road plate, and one side of the drainage groove close to the road plate is arranged in an inclined plane shape.

[0011] A plurality of drainage ports are opened at the bottom of the structural frame, and the plurality of drainage ports are arranged in a circumferential shape at the bottom of the structural frame.

[0012] Beneficial effects

[0013] 1. Through the installation component, the rapid connection between road plates can be realized, the paving efficiency can be improved, and it is applicable to various terrains and emergency passage scenarios. It has a buffering effect and can absorb vibration and shear forces under traffic, settlement or impact, reduce joint stress, prevent dislocation and damage, and extend the service life.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-6 This invention describes a prefabricated reinforced concrete temporary roadway.

[0026] In one embodiment, a prefabricated reinforced concrete temporary roadway includes: a road slab 100, the surface of which has a plurality of lifting holes 200; an assembly mechanism 300, which is disposed on the outside of the road slab 100 for rapid assembly of the plurality of road slabs 100; wherein, the assembly mechanism 300 includes a structural frame 310 fixedly installed at the bottom of the road slab 100, an installation component 320 for connecting adjacent road slabs 100 is disposed on the outside of the structural frame 310, and a drainage component 330 is disposed on the outside of the road slab 100.

[0027] In this embodiment, by setting the installation component 320, the rapid assembly and connection between multiple road slabs 100 can be realized, which significantly improves construction efficiency, meets the actual needs of construction sites for the rapid paving and opening of temporary roads, and is applicable to various complex terrains and emergency traffic organization scenarios. The installation component 320 has a certain buffering performance. Under the action of frequent vehicle traffic, slight foundation settlement or external impact, it can effectively absorb the vibration and shear force between adjacent road slabs 100, reduce stress concentration at the joints, prevent the road slabs 100 from being misaligned, warped or damaged, and improve the service life and safety of the overall structure. The drainage component 330 can quickly drain water from the road surface in rainy and snowy weather, prevent rainwater accumulation from causing the road surface to slip, water accumulation or structural subsidence, and improve traffic safety and the adaptability of temporary roads.

[0028] It should be noted that existing precast reinforced concrete pavements typically include a pavement slab 100 formed by pouring concrete, with a steel reinforcement skeleton embedded inside to enhance the overall load-bearing capacity. The surface is generally a flat structure to accommodate vehicle traffic needs, and the bottom may be equipped with reinforcing ribs 311 or a groove structure for resistance to deformation and ease of hoisting and installation.

[0029] The assembly mechanism 300 uses the structural frame 310 as the mounting base, and the mounting components 320 are installed on its side to achieve stable splicing of adjacent road slabs 100; the drainage components 330 are arranged on the edge or bottom guide groove area of ​​the road slab 100 to prevent rainwater from accumulating on the slab surface, while not interfering with the vehicle wheel pressure path, not damaging the overall stress path, and not affecting construction, traffic or subsequent disassembly and assembly operations.

[0030] like Figure 3 , Figure 4 and Figure 5 As shown, the mounting component 320 includes two fixing blocks 321 fixedly installed on one side of the structural frame 310, and two connecting blocks 322 provided on the other side of the structural frame 310. A positioning block 323 is fixedly installed inside the fixing block 321, and a positioning groove 324 is provided at the bottom of the connecting block 322. The positioning groove 324 and the connecting block 322 are adapted to each other.

[0031] In this embodiment, the connecting block 322 of the adjacent road panel 100 can be brought close to the corresponding fixing block 321. The positioning groove 324 of the connecting block 322 and the positioning block 323 of the fixing block 321 can be quickly plugged in and matched to complete the efficient assembly. It can complete the precise positioning and connection without relying on additional tools, which significantly shortens the on-site construction time.

[0032] Two connecting rods 325 are fixedly installed on the other side of the structural frame 310. Two sealing tubes 326 are fixedly installed on the side of the two connecting blocks 322 near the structural frame 310. The two sealing tubes 326 are slidably connected to the two connecting rods 325 respectively.

[0033] In this embodiment, the installation component 320, while enabling rapid splicing of adjacent road panels 100, also possesses a certain degree of flexible buffering and sealing transition capability. After the sealing tube 326 is fitted onto the connecting rod 325, it provides a small amount of sliding adjustment space when the road panel 100 is subjected to pressure or displacement, absorbing local stress at the splicing gaps and preventing local cracking or interface deformation caused by rigid connections. Simultaneously, the sealing tube 326 contains damping silicone oil, which provides damping when the connecting rod 325 slides, further mitigating the impact and micro-vibrations caused by vehicle loads, thermal expansion and contraction, or uneven foundation settlement, maintaining a stable sealing state at the interface, and extending the service life of the installation component 320.

[0034] A spring 327 is fixedly installed inside the sealing tube 326, and the other end of the spring 327 is fixedly connected to one end of the connecting rod 325.

[0035] In this embodiment, when adjacent road slabs 100 experience relative displacement due to traffic loads or slight foundation settlement, the spring 327 can be compressed or extended under the action of the sliding fit structure, thereby absorbing external impact forces, reducing local stress concentration, and effectively preventing cracking or loosening of the connection. Furthermore, the spring 327 can quickly return to its original state after the external force is released, driving the sealing tube 326 back to its original position, thus ensuring the stability and long-term sealing of the connection.

[0036] The structural frame 310 is internally fixedly installed with a steel mesh 110, and multiple reinforcing ribs 311 are externally fixedly installed on the structural frame 310. The tops of the multiple reinforcing ribs 311 are all fixedly connected to the bottom of the road slab 100.

[0037] In this embodiment, the multiple reinforcing ribs 311 provided on the outside of the structural frame 310 can significantly improve the overall rigidity and deformation resistance of the bottom structure, so that the road slab 100 can maintain good structural stability even if it encounters uneven settlement or lateral disturbance during construction or use. In addition, the top of the reinforcing ribs 311 is fixedly connected to the bottom of the road slab 100, so that the structural frame 310 and the road slab 100 form an integrated reinforcement system, which improves the load-bearing capacity and fatigue resistance of the overall assembled structure and extends the service life of the temporary road intersection.

[0038] The structural frame 310 is set in a U-shape, and the steel mesh 110 is located inside the structural frame 310.

[0039] In this embodiment, the structural frame 310 adopts a U-shaped design, which effectively improves the overall stiffness and crack resistance of the road slab 100 under vertical load. The steel mesh 110 is arranged inside the structural frame 310, making the stress path more continuous and uniform. It can work together with the concrete to bear bending and shear stress, thereby enhancing the overall stability and load-bearing capacity of the structure.

[0040] like Figure 3and Figure 6 As shown, the drainage assembly 330 includes a drainage channel 331 formed on the top edge of the road slab 100, and the side of the drainage channel 331 facing the road slab 100 is all set as a slope.

[0041] In this embodiment, a drainage trough 331 is provided on the top edge of the road slab 100, allowing rainwater or wash water to quickly collect and flow along the road edge, effectively preventing water from accumulating on the surface of the road slab 100, reducing the risk of slipping, and ensuring traffic safety. The drainage trough 331 is designed with a sloping structure, which can naturally guide the water flow by gravity, allowing the water to flow smoothly into the drainage system or temporary drainage ditch on both sides of the road, improving drainage efficiency.

[0042] The bottom of the structural frame 310 is provided with multiple drainage outlets 332, which are arranged in a ring around the bottom of the structural frame 310.

[0043] In this embodiment, the multiple drainage outlets 332 provided at the bottom of the structural frame 310 are arranged in a ring shape, which can provide a fast drainage channel when rainwater or construction flushing water seeps into the internal structure of the road slab 100, and avoid water stagnation inside the structural frame 310 causing problems such as water accumulation and corrosion. Through the ring arrangement, multiple points can be drained at the same time, effectively reducing local drainage pressure and improving drainage efficiency.

[0044] Working principle: Multiple road slabs 100 are sequentially hoisted to the paving area through the hoisting holes 200 and quickly spliced ​​using the assembly mechanism 300. When two adjacent road slabs 100 are joined, the connecting block 322 is inserted into the corresponding fixing block 321, and the positioning block 323 cooperates with the positioning groove 324 to complete the initial positioning; the connecting rod 325 is fitted into the sealing tube 326, and the sealing tube 326 remains in a stable and close fit under the elastic force of the spring 327, thus forming a flexible buffer and sealing connection. When a vehicle passes, the small displacement caused by dynamic load or micro-settlement of the foundation will be absorbed by the sealing tube 326 and the spring 327, preventing the joint from cracking or misaligning. The structural frame 310 serves as the supporting base, and the steel mesh 110 inside enhances the overall compressive and crack resistance. The reinforcing ribs 311 are firmly connected to the bottom of the road slabs 100, improving the structural stability. The drainage groove 331 set on the top edge of the road slab 100 can quickly collect surface rainwater or washing water to the edge and discharge it along the slope. The multiple drainage outlets 332 opened at the bottom of the structural frame 310 can quickly drain water that may seep into the structure, preventing water accumulation, corrosion or freezing.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
