[0002] In the field of construction, especially in large-scale highway, bridge, infrastructure construction and other projects, the construction of temporary construction roads is an indispensable part. These temporary roads not only carry the transportation tasks of construction equipment and materials, but also ensure the passage safety of construction workers.

[0003] At present, the temporary construction roads at the construction sites of domestic engineering projects mostly adopt cast-in-place concrete pavement structures to achieve site hardening, meet the requirements of in-site traffic and prevent dust. However, after the cast-in-place cement concrete pavement structure is completed, it needs to be maintained with moisture, and the maintenance time is generally not less than 28 days, resulting in a delay in the use time, thus affecting the project progress. In addition, most of the hardened sites at the construction sites need to be demolished after the construction is completed, which will inevitably waste a large amount of labor and materials and generate a large amount of construction waste, causing harm to the environment. This is contrary to the requirements of green construction, energy conservation and environmental protection advocated by the country. Therefore, a precast temporary construction road panel is proposed to solve the above problems. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figure 1 - Figure 3, an embodiment provided by the utility model: an assembled temporary construction road panel, including road panel 1, a steel bar 6 is fixedly connected to the front end of road panel 1, connecting road panel 1 and road panel 2, enhancing the connection strength and stability between the two panels, preventing dislocation or separation during use. Road panel 2 is arranged at the front end of road panel 1. Road panel 1 and road panel 2 are concrete assembly panels, which are the main load-bearing components of the assembled temporary construction road, used to form the surface of the road and bear the loads of vehicles and pedestrians. A reserved hole 7 is opened at the rear side of road panel 2, used to accommodate the front end of the steel bar 6, so that road panel 1 and road panel 2 can be accurately docked and fixed through the steel bar 6. The outer wall of the front end of the steel bar 6 is inserted into the inner wall of the reserved hole 7. Installation grooves 3 are opened on the outer sides of the front end of road panel 1 and the rear end of road panel 2, providing an installation position for the protection component, ensuring that the protection component can be stably installed on the outer sides of road panel 1 and road panel 2. A protection component is arranged on the inner wall of the installation groove 3. The protection component includes a connector 41. The inner side of the connector 41 slides on the inner wall of the installation groove 3. Through the installation groove 3, the top surface of the connector 41 can be flush with the top surfaces of road panel 1 and road panel 2, ensuring the flatness of the road surface. Vehicles and pedestrians will not jolt or feel uncomfortable due to the uneven top surface of the connector 41 when passing through. In terms of appearance, the flush design makes the road more beautiful and regular as a whole. A cover plate 42 is arranged on the left side of the top end of the connector 41. The cover plate 42 is connected to the connector 41 through a hinge, covering and protecting the high-strength bolt 43, preventing the high-strength bolt 43 from being directly exposed to the external environment, reducing the erosion and pollution of the bolt by rainwater, dust, sundries, etc., thereby extending the service life of the bolt, ensuring the stability and reliability of its connection, and at the same time avoiding accidental collision or damage to the bolt, reducing the risk of bolt loosening or failure.

[0033] Refer to Figure 1 , Figure 4 and Figure 5, a buffer gasket 44 is provided on the inner wall of the bottom end of the adapter 41, which plays a buffering role between the high-strength bolt 43 and the adapter 41, reducing the impact force and vibration during the tightening of the high-strength bolt 43 on the structure. An installation hole 5 is penetrated and opened at the top end of the installation groove 3, and the high-strength bolt 43 is inserted into the inner wall of the installation hole 5, which is used to connect the two sides of the road surface slab 1 and the road surface slab 2. While improving the strength of the joint of the assembled road surface slab, it also reduces the damage to the road edges on both sides of the assembled road surface slab. The outer wall of the high-strength bolt 43 is slidably connected through the inner wall of the top end of the adapter 41, firmly fixing the adapter 41 in the installation groove 3 to ensure the reliability of the connection. The bottom end of the high-strength bolt 43 is threadedly connected to the inner wall of the top end of the buffer gasket 44. A fixing block 45 is fixedly connected to the top end of the adapter 41, which cooperates with the limiting rod 46 to fix the position of the cover plate 42 and prevent the cover plate 42 from being accidentally opened. The limiting rod 46 is slidably connected to the inner wall of the cover plate 42, and the movement of the cover plate 42 is restricted through the insertion and cooperation with the fixing block 45 to keep the cover plate 42 in a closed state. The limiting rod 46 and the cover plate 42 are elastically connected by a return spring 47, enabling the limiting rod 46 to have the ability of elastic reset, which is convenient for operating the insertion and separation of the limiting rod 46 and the fixing block 45. The right side of the limiting rod 46 is inserted into the left inner wall of the fixing block 45. The limiting rod 46 is set in a T shape. A storage groove is opened on the cover plate 42 near the T-shaped cross bar of the limiting rod 46. The T-shaped cross bar part can increase the operation convenience. At the same time, the storage groove opened on the cover plate 42 provides a accommodation space for the T-shaped cross bar, making the structure more compact and avoiding the cross bar from affecting the complete opening of the cover plate 42. The adapter 41 is set in a U shape, which can better fit the installation groove 3 and provide sufficient connection and fixing area, enhancing the connection stability between the road surface slab 1 and the road surface slab 2. There are multiple groups of steel bars 6 and reserved holes 7. The cooperation of multiple groups of steel bars 6 and reserved holes 7 can make the connection between the road surface slab 1 and the road surface slab 2 more firm and uniform, disperse the force, and improve the overall bearing capacity and durability of the road surface slab.

[0034] Refer to Figure 1 , Figure 2 and Figure 6, there are multiple groups of protective components, and the multiple groups of protective components are symmetrically arranged with the center line of the first road panel 1 and the second road panel 2 as the axis of symmetry, making the force at the connection between the first road panel 1 and the second road panel 2 more uniform, enhancing the stability and reliability of the connection. There are tooth grooves opened between the first road panel 1 and the second road panel 2, providing an installation space for the buffer component. The inner wall of the tooth groove is provided with a buffer component, and the buffer component includes a joint buffer belt 81. The outer wall of the joint buffer belt 81 slides on the inner wall of the tooth groove, which can play a buffering role between the first road panel 1 and the second road panel 2, reducing the damage to the road structure caused by the impact and vibration generated when the vehicle passes, and at the same time can also be used as a speed bump for the temporary construction road, indirectly reducing the wear of the assembled road panel, improving the turnover efficiency of the assembly plate, saving energy and protecting the environment, and also providing convenience for the engineering construction. The surface of the joint buffer belt 81 is penetrated with fixing holes 82, so that the joint buffer belt 81 can be accurately installed at the specified position. The number of fixing holes 82 opened is the same as the number of steel bars 6. The inner wall of the fixing hole 82 slides on the outer wall of the steel bar 6. The cooperation of the fixing hole 82 and the steel bar 6 further enhances the buffering effect and also ensures the stability of the buffer belt during use, and it will not be easily displaced or fall off. The joint buffer belt 81 is made of rubber material and has good elasticity and buffering performance.

[0035] Working principle: When in use, when assembling the temporary construction road panel, first put the joint buffer belt 81 made of rubber material on the outer wall of the steel bar 6 through the fixing holes 82 on its surface. At this time, insert the steel bar 6 at the front end of the first road panel 1 into the reserved hole 7 at the rear side of the second road panel 2 to achieve preliminary positioning and connection. The cooperation of multiple groups of steel bars 6 and the reserved holes 7 makes the connection between the two panels more firm and uniform, disperses the force, improves the overall bearing capacity, and at the same time installs the joint buffer belt 81 in the tooth groove between the first road panel 1 and the second road panel 2 to enhance the buffering effect and ensure the stability of the buffer belt.

[0036] Then, slide the inner side of the adapter 41 of the protective component into the installation groove 3, insert the high-strength bolt 43 into the top end of the adapter 41, and then insert it into the installation hole 5 and thread it with the buffer gasket 44 to reduce the impact force and vibration influence during bolt tightening, and at the same time fix the adapter 41 in the installation groove 3, thereby strengthening the connection on the outer sides of the first road panel 1 and the second road panel 2.

[0037] Then, cover the cover plate 42. Through the action of the return spring 47, the right side of the limit rod 46 is inserted into the left inner wall of the fixed block 45 to fix the cover plate 42 to prevent it from being accidentally opened. At the same time, the cover plate 42 plays a role in covering and protecting the high-strength bolt 43.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
