Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete road slabs, and in particular to a permanent and temporary combined precast concrete road slab. Background Technology
[0002] In the field of road construction, the efficient construction of temporary roads has always been a key focus. As the scale of project construction continues to expand and the construction period becomes increasingly tight, the frequency and importance of the use of temporary roads are increasing day by day.
[0003] Currently, cast-in-place concrete is commonly used to construct temporary roads. However, traditional cast-in-place concrete temporary roads require on-site formwork, pouring, vibration, and curing, which are cumbersome procedures and highly dependent on the construction site and weather conditions. Moreover, traditional temporary roads need to be demolished after the project is completed. This demolition process not only consumes a lot of manpower, material resources, and time, but also generates a lot of construction waste and increases construction costs. To address these issues, we propose a combined permanent and temporary precast concrete road slab. Utility Model Content
[0004] The purpose of this utility model is to provide a permanent and temporary combined precast concrete road slab to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A type of precast concrete road slab that combines permanent and temporary use includes multiple concrete road main panels. Each concrete road main panel has two sets of concrete road side panels on its exterior. The two sets of concrete road side panels have connecting protrusions at their adjacent ends. The two connecting protrusions have limiting grooves on their adjacent sides. The two limiting grooves have T-shaped splicing parts inside them. Each concrete road main panel has a connecting groove on its upper surface. The two concrete road side panels have L-shaped protrusions on their adjacent sides.
[0006] In a further embodiment, the ends of the two sets of L-shaped protrusions that are close to each other extend into the interior of the two sets of connecting grooves, and the outer surface of the L-shaped protrusions contacts the inner wall of the connecting groove.
[0007] In a further embodiment, the concrete road main board includes a concrete layer, a steel wire reinforcing mesh is fixedly embedded inside the concrete layer, and a plurality of first reinforcing bars are embedded in the interior of the concrete layer and the outer surface of the steel wire reinforcing mesh.
[0008] In a further embodiment, two sets of second reinforcing steel bars are fixedly embedded inside the concrete layer, and two sets of metal reinforcing corner plates are fixedly embedded inside the concrete layer.
[0009] In a further embodiment, the bottom surface of both concrete road main boards is provided with recessed holes, and the inner walls of both recessed holes are fixedly inlaid with lifting components.
[0010] In a further embodiment, the two sets of concrete road side panels are close to each other on one side and respectively contact the outer surface of each concrete road main board. The two concrete road side panels are far apart on one side and are provided with lifting holes. The upper surfaces of the two T-shaped splicing parts are provided with fixing holes.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention enables rapid connection between concrete road side panels through the cooperation of the limiting groove of the concrete road side panel and the T-shaped splicing component. Furthermore, the splicing of the main concrete road panel with the L-shaped protrusion at the concrete road side panel eliminates the need for complex on-site operations. Additionally, the road slab is prefabricated, allowing for easy hoisting of the concrete road side panels and main concrete road panel during construction. After completion, its stable structure allows for reuse or modification, avoiding demolition losses, reducing resource waste, and lowering construction costs. Through the steel wire reinforcement mesh, first reinforcing bars, second reinforcing bars, and metal reinforcing corner plates embedded in the concrete layer, the overall strength and stability of the road slab are enhanced compared to traditional cast-in-place roads, ensuring it can withstand various loads during temporary use and guaranteeing road performance and safety.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0017] Please see Figures 1-4In this utility model, a permanent and temporary combined precast concrete road slab includes multiple concrete road main panels 1. Each concrete road main panel 1 has two sets of concrete road side panels 2 on its exterior. A connecting protrusion 3 is provided at the end of each set of concrete road side panels 2 that is close to each other. A limiting groove 4 is provided on the side of each connecting protrusion 3 that is close to each other. A T-shaped splicing member 5 is provided inside the two limiting grooves 4. A connecting groove 7 is provided on the upper surface of each concrete road main panel 1. An L-shaped protrusion 6 is provided on the side of each set of concrete road side panels 2 that is close to each other. Main board 1 is the main body of the road slab, providing the basic load-bearing plane. Through concrete road side plate 2, connecting protrusion 3, limiting groove 4, and T-shaped splicing piece 5, a transverse connection structure of the road slab can be formed. By inserting the T-shaped splicing piece 5 into the limiting groove 4, the concrete road side plate 2 of the adjacent road slab can be accurately positioned, enhancing transverse stability. The L-shaped protrusion 6 on the concrete road side plate 2 cooperates with the connecting groove 7 of the concrete road main board 1 to achieve a longitudinal and stable splicing of the concrete road side plate 2 and the concrete road main board 1, forming a complete road paving unit, which is convenient for quick installation and disassembly. In a further embodiment, the ends of the two sets of L-shaped protrusions 6 that are close to each other extend into the interior of the two sets of connecting grooves 7, and the outer surface of the L-shaped protrusions 6 contacts the inner wall of the connecting grooves 7. The bottom surfaces of the two concrete road main plates 1 are provided with recessed holes 8, and the inner walls of the two recessed holes 8 are fixedly embedded with lifting components 11. The sides of the two sets of concrete road side plates 2 that are close to each other contact the outer surface of each concrete road main plate 1, and the sides of the two concrete road side plates 2 that are far apart from each other are provided with lifting holes 10. The upper surfaces of the two T-shaped splicing parts 5 are provided with fixing holes 9. The close contact between the L-shaped protrusions 6 and the connecting grooves 7 enhances the connection strength between the concrete road side plates 2 and the concrete road main plates 1, preventing loosening during use. The lifting components 11 on the bottom surface of the concrete road main plates 1 and the lifting holes 10 on the concrete road side plates 2 facilitate the lifting, transportation and on-site installation of the road slabs. The fixing holes 9 on the T-shaped splicing parts 5 can be used with fixing components to firmly fix the T-shaped splicing parts 5, ensuring the stability of the lateral connection of the road slabs. In a further embodiment, the concrete road main board 1 includes a concrete layer 101. A steel wire reinforcing mesh 102 is fixedly embedded inside the concrete layer 101. Multiple first reinforcing bars 103 are embedded both inside the concrete layer 101 and on the outer surface of the steel wire reinforcing mesh 102. Two sets of second reinforcing bars 104 are fixedly embedded inside the concrete layer 101. Two sets of metal reinforcing corner plates 105 are fixedly embedded inside the concrete layer 101. The concrete layer 101 is the base material of the concrete road main board 1, providing basic strength. The steel wire reinforcing mesh 102 can evenly distribute pressure and enhance the crack resistance of the concrete layer 101. The first reinforcing bars 103 and the second reinforcing bars 104 are arranged in different directions to improve the overall tensile and compressive strength of the concrete road main board 1. In addition, the metal reinforcing corner plates 105 can reinforce the corners of the concrete road main board 1 to prevent the corners from being damaged due to concentrated force during transportation and use, thus ensuring the integrity and service life of the road board.
[0018] The working principle of this utility model is as follows: First, the adjacent concrete road side panels 2 are aligned and contacted. Then, the T-shaped splicing piece 5 is taken and placed inside the two limiting grooves 4, which allows the adjacent concrete road side panels 2 to be connected. Next, the concrete road main panel 1 is hoisted and the connecting groove 7 on the surface of the concrete road main panel 1 is positioned above the L-shaped protrusion 6. Then, the concrete road main panel 1 is loosened downwards, which allows the concrete road main panel 1 and the concrete road side panel 2 to be stably spliced. Then, a temporary road is formed between the concrete road main panel 1 and the concrete road side panel 2. Compared with the cumbersome procedures of on-site formwork, pouring, vibration and curing of cast-in-place concrete roads, the construction efficiency is improved.
