Description

Technical Field

[0001] The present invention relates to the technical field of temporary road surfaces, and in particular, to a quick-laying road panel. Background Art

[0002] Road panels are mainly used for laying on soft ground to ensure that rescue equipment and personnel can pass smoothly on the soft ground. The quick-laying road panel is characterized by simple assembly, high assembly efficiency. In special cases, 2-3 people can assemble it manually, and it has the characteristic of large load-bearing capacity. Therefore, when disasters such as tunnel collapses and water inrushes occur and emergency rescue is required, a simple and temporary rescue access road can be quickly built for equipment and personnel to enter the site.

[0003] At present, common materials for quick-laying road panels include cement concrete, steel plates, aluminum alloys and composite materials. Their load-bearing capacity is positively correlated with the size and quality of the road panel, and the current maintenance is very inconvenient, affecting rescue operations. Therefore, considering the assembly efficiency, load-bearing capacity and maintenance performance of the road panel comprehensively, it is very necessary to use aluminum alloy for the assembled road panel and design a road panel that can be quickly installed and a maintenance board that is easy to maintain. Summary of the Invention

[0004] The present invention provides a quick-laying road panel to solve the technical problem that it is difficult to perform partial repair when the existing quick-laying road panel has permanent damage.

Two first through holes are symmetrically provided at both ends. The first through holes away from the center of the first joint unit and the last joint unit among the multiple serially connected joint units are used to fix the repair joint to the ground, and the first through holes close to the center and the two first through holes of other joint units are all used to achieve detachable connection between joint units.

[0011] Further, the repair joint further includes a connecting rod. Two second through holes are symmetrically provided at both ends of the connecting rod. The connecting rod is placed at the ends of two adjacent joint units, and two countersunk bolts respectively pass through the first through holes of the joint unit and the second through holes of the connecting rod in sequence to realize the fixed connection of two adjacent joint units.

[0012] Further, the main panel and the half panel successively include an upper skin, an intermediate layer, and a lower skin from top to bottom.

[0048] Such as Figures 1 - 15As shown in the figure, an embodiment of the present invention discloses a quick-laying road panel, which includes a maintenance joint 10, a main board 20 and a maintenance board 30. The maintenance joint 10 is formed by connecting a plurality of detachable joint units 11. The main board 20 includes a main panel 211 and a half panel 212. The main panel 211 and the half panel 212 are laid at intervals on both sides of the maintenance joint 10. The length dimension of the main panel 211 is greater than the length dimension of the half panel 212, so that the connection points in the width direction of two adjacent rows of the main boards 20 after laying are not on the same straight line;

[0049] One side of the length direction of the main panel 211 and the half panel 212 is a female joint 13, and the other side is a male joint 31 that matches the female joint 13; one end of the width direction of the main panel 211 and the half panel 212 is an upper joint 25, and the other end is a lower joint 52 that matches the upper joint 25. After the upper joint 25 and the lower joint 52 are buckled, a rectangular channel is formed for the insertion of a pin 26;

[0050] The maintenance board 30 is used to replace the damaged main board 20, and includes two triangular male maintenance boards 32 and female maintenance boards 33, and an intermediate joint 34. The hypotenuse of the male maintenance board 32 is the lower joint 52, and the hypotenuse of the female maintenance board 33 is the lower half of the upper joint 25. One side of the intermediate joint 34 is the upper half of the upper joint 25; after the male maintenance board 32, the female maintenance board 33 and the intermediate joint 34 are buckled, a rectangular channel is formed for the insertion of a pin 26;

[0051] The maintenance board 30 further includes a first assembled joint 35. One side of the first assembled joint 35 is the upper half of the lower joint 52. The short side of the male maintenance board 32 is the lower half of the lower joint 52. After the short side of the male maintenance board 32, one side of the first assembled joint 35 and the upper joint 25 of the main board 20 are buckled, a rectangular channel is formed for the insertion of a pin 26;

[0052] The maintenance board 30 further includes a second assembled joint 36. One side of the second assembled joint 36 is the upper half of the upper joint 25. The short side of the female maintenance board 33 is the lower half of the upper joint 25. After the short side of the female maintenance board 33, one side of the second assembled joint 36 and the lower joint 52 of the main board 20 are buckled, a rectangular channel is formed for the insertion of a pin 26.

[0053] According to an embodiment of the present application, the quick-laying pavement slab includes a maintenance joint 10, a main slab 211, and a half slab 212. The joint structure between each component is simple. Only by means of assembly and pins, the laying can be completed, greatly improving the construction efficiency. The joints are divided into four joint forms and two assembly methods. Due to its high efficiency, a variety of different pavement slabs and combined joints can be designed, which can be flexibly applied to various scenarios. Moreover, the "bricklaying" type of assembly method is adopted to stagger the connection parts, enhancing the overall anti-fatigue performance.

[0054] When laying the quick-laying pavement slab, the maintenance joints 10 can be laid at a certain interval. When a large area of the main slab 20 is damaged, the relatively adjacent maintenance joints 10 can be removed, and then the damaged main slabs 20 can be removed in sequence. Finally, the new main slabs 20 and maintenance joints 10 are installed in sequence to complete the repair of the large-area damage. The quick-laying pavement slab provided by the present invention further includes a maintenance plate 10. When a single main slab 20 is damaged, the damaged main slab 20 can be removed by cutting, and then the maintenance plate 10 is installed to complete the repair of the single main slab 20 damage. Of course, when repairing large-area damage, the maintenance plate 10 can also be installed at the position of the last row of main slabs 20 or the last main slab 20. The installation of the maintenance plate 10 will not be restricted by the installation space, and the operation is more convenient.

[0055] In some embodiments, the pin 26 is a cuboid, and its length has various dimensions, which can match different application scenarios. For example, when the pin 26 is applied between the upper joint 25 and the lower joint 52 of the main slab 20, its length matches the length of the main slab 20 in the width direction, and the three form a firm plug-in connection;

[0056] When the pin 26 is applied to the hypotenuse of the male maintenance plate 32 and the female maintenance plate 33, and between the middle joint 34, its length is the same as the length of the middle joint 34, and at the same time, it is also equal to the length of the hypotenuse of the male maintenance plate 32 and the female maintenance plate 33, and the four form a firm plug-in connection;

[0057] In addition, when the pin 26 is applied to the short side of the male maintenance plate 32, one side of the first assembled joint 35 and the upper joint 25 of the main slab 20, its length is the same as the short side of the male maintenance plate 32, and at the same time, it is also equal to the length of the first assembled joint 35, and the four form a firm plug-in connection;

[0058] Similarly, when the pin 26 is applied to the short side of the female maintenance plate 33, one side of the second assembled joint 36 and the lower joint 52 of the main slab 20, its length is equal to the length of the short side of the female maintenance plate 33, and at the same time, it is also equal to the length of the second assembled joint 36, and the four form a firm plug-in connection.

[0059] In an embodiment of the present application, the size of the maintenance board 30 after assembly is the same as that of the main board 20. That is to say, the size of the maintenance board 30 can be of two types. After assembly, it can be equal to the size of the main panel 211 or equal to the size of the half panel 212. In addition, the internal structures of the male maintenance board (32) and the female maintenance board (33) can be the same as or different from the internal structure of the main board 20.

[0060] In an embodiment of the present application, the joint unit 11 is a hollow cuboid. One side in the length direction is the female joint 13, and the other side is the male joint 31. Two first through holes 12 are symmetrically arranged at both ends. The first through holes 12 far from the center of the first joint unit 11 and the last joint unit 11 among the plurality of successively connected joint units 11 are used to fix the maintenance joint 10 to the ground, and the first through holes 12 close to the center and the two first through holes 12 of the other joint units 11 are all used to achieve detachable connection between the joint units 11.

[0061] According to an embodiment of the present application, after the maintenance joint 10 is fixed, the main board 20 is laid starting from both sides with it as a reference. The maintenance joint 10 can not only play a fixing role, but also be convenient for disassembly when large-area damage repair of the main board 20 is required.

[0062] In an embodiment of the present application, the maintenance joint 10 further includes a connecting rod 15. Two second through holes 16 are symmetrically arranged at both ends of the connecting rod 15. The connecting rod 15 is placed at the ends of two adjacent joint units 11. Two countersunk head bolts 17 respectively pass through the first through holes 12 of the joint unit 11 and the second through holes 16 of the connecting rod 15 in sequence to achieve fixed connection between two adjacent joint units 11.

[0063] According to an embodiment of the present application, when the maintenance joint 10 needs to be disassembled, the fixing between both ends of the maintenance joint 10 and the ground can be released first, then the countersunk head bolts between the joint units 11 are removed, and finally the joint units 11 are removed in sequence.

[0064] In an embodiment of the present application, the main board 20 includes a main panel 211 and a half panel 212. The main panel 211 and the half panel 212 are laid at intervals along both sides of the maintenance joint 10. The width dimension of the main panel 211 is equal to the width dimension of the half panel 212, and other structures are also the same. The difference is only that: the length dimension of the main panel 211 is greater than the length dimension of the half panel 212. Such a design can make the connection at the width direction of two adjacent panels 21 after laying not on the same straight line, so that the overall anti-fatigue performance of the pavement panel is better.

[0065] For example, the length dimension of the main panel 211 can be twice that of the half panel 212. The long side dimension of the main board 20 can be 1000 - 5000 mm, the short side dimension can be 500 - 1000 mm, and the thickness can be 35 - 50 mm. Adopting the "bricklaying" laying mode, the connections of two adjacent panels 21 in the width direction after laying are not on the same straight line, and the above method can make the connection of the pavement slabs after laying more stable.

[0066] In the embodiments of the present application, the main panel 211 and the half panel 212 successively include an upper skin 22, an intermediate layer 23, and a lower skin 24 from top to bottom. The intermediate layer 23 is provided with triangular rib plates, and the voids of the triangular rib plates are filled with resin or fibers; or the intermediate layer is provided with vertical rib plates and honeycomb aluminum; or the intermediate layer is provided with vertical rib plates, and the voids of the vertical rib plates are filled with resin or fibers.

[0067] According to the embodiments of the present application, the main board 20 itself includes an upper skin 22, an intermediate layer, a lower skin 24, a male joint 31, a female joint 13, an upper joint 25, and a lower joint 52. The intermediate layer 23 and the upper and lower skins 24 adopt an integral brazing technology or are formed in one step by an extrusion molding process. The male joint 31 and the female joint 13 are welded in the long side direction of the main board 20, and the upper joint 25 and the lower joint 52 are welded in the short side.

[0068] In some embodiments, the intermediate layer 23 is arranged with strengthened triangular rib plates, and resin or composite fillers can be filled in the middle to enhance the load-bearing capacity of the pavement slab. Optionally, the intermediate layer 23 can adopt equally spaced reinforcing rib plates (the thickness can be 1 - 5 mm), or honeycomb aluminum alloy, or honeycomb aluminum alloy is arranged between the equally spaced reinforcing rib plates to enhance the load-bearing capacity of the pavement slab.

[0069] In some embodiments, the upper skin 22 (the thickness can be 3 - 6 mm) is sprayed with an anti-slip material to increase the surface friction. The main board 20 adopts an overall anti-corrosion measure, such as anodic oxidation, to make it have anti-corrosion performance.

[0070] In the embodiments of the present application, the female joint 13 has a concave portion, forming an inwardly concave accommodating structure, and the male joint 31 has a convex portion, which is an outwardly convex structure to be accommodated. The convex portion is engaged into the concave portion so that the male joint 31 and the female joint 13 are fixedly connected.

[0071] As Figure 7 shown, the concave portion of the female joint 13 is an accommodating structure similar to a "C" shape; the male joint 31 is divided into a first convex portion and a second convex portion. After the male joint 31 is inserted into the female joint 13, the first convex portion and the second convex portion form an engagement with the "C" - shaped concave portion.

[0072] According to an embodiment of the present application, the length directions of the main panel 211 and the half panel 212 are laid by connecting the male connector 31 and the female connector 13, which is not only convenient for installation but also firmly connected.

[0073] In an embodiment of the present application, as Figure 8 shown, the upper joint 25 has two downwardly facing fastening portions and a first groove, and the lower joint 52 has two symmetrically upwardly facing fastening portions and a second groove. When the upper joint 25 is fixedly connected to the lower joint 52, the four pairwise symmetric fastening portions are engaged with each other, and the first groove and the second groove form a rectangular parallelepiped channel for the insertion pin 26 to be inserted.

[0074] In an embodiment of the present application, the long side of the male repair board 32 is the male connector 31, and the male connector 31 matches the female connector 13 of the main board 20.

[0075] According to an embodiment of the present application, the long side of the male repair board 32 is the male connector 31, and one side in the length direction of the main board 20 (which can be the main panel 211 or the half panel 212) is the female connector 13. When they are installed, the male connector 31 and the female connector 13 are matched, so that the male repair board 32 is firmly engaged with the main board 20.

[0076] In an embodiment of the present application, the long side of the female repair board 33 is the female connector 13, and the female connector 13 matches the male connector 31 of the main board 20.

[0077] According to an embodiment of the present application, the long side of the female repair board 33 is the female connector 13, and one side in the length direction of the main board 20 (which can be the main panel 211 or the half panel 212) is the male connector 31. When they are installed, the female connector 13 and the male connector 31 are matched, so that the female repair board 33 is firmly engaged with the main board 20.

[0078] In an embodiment of the present application, a third through hole 341 is provided on the intermediate joint 34, and the third through hole 341 is used to fixedly connect the intermediate joint 34 to the hypotenuse of the female repair board 33 to form a complete upper joint 25.

[0079] According to an embodiment of the present application, the hypotenuse of the female repair board 33 is the lower half of the upper joint 25, and one side of the intermediate joint 34 is the upper half of the upper joint 25. After they are spliced and fixed, a complete upper joint 25 is formed. The hypotenuse of the male repair board 32 is the complete lower joint 52. After the male repair board 32, the female repair board 33, and the intermediate joint 34 are engaged, a rectangular parallelepiped channel is formed for the insertion pin 26 to be inserted, so that the male repair board 32 and the female repair board 33 form a stable connection, and at the same time, there is no space limitation during installation, which is convenient for the insertion pin 26 to be inserted.

[0080] In an embodiment of the present application, a fourth through hole 351 is provided on the first prefabricated joint 35. The fourth through hole 351 is used to fixedly connect the first prefabricated joint 35 to the short side of the male maintenance plate 32 to form a complete lower joint 52. A fifth through hole 361 is provided on the second prefabricated joint 36. The fifth through hole 361 is used to fixedly connect the second prefabricated joint 36 to the short side of the female maintenance plate 33 to form a complete upper joint 25.

[0081] According to an embodiment of the present application, a fourth through hole 351 is provided on the first prefabricated joint 35. The fourth through hole 351 is used to fixedly connect the first prefabricated joint 35 to the short side of the male maintenance plate 32 to form a complete lower joint 52, and one end in the width direction of the main board 20 (which can be the main panel 211 or the half panel 212) is the upper joint 25. After the short side of the male maintenance plate 32, one side of the first prefabricated joint 35 is buckled with the upper joint 25 of the main board 20, a rectangular channel is formed for the insertion pin 26 to insert, so that the male maintenance plate 32 and the main board 20 form a firm connection, and at the same time, there is no space limitation during installation, which is convenient for the insertion pin 26 to insert. Similarly, after the short side of the female maintenance plate 33, one side of the second prefabricated joint 36 is buckled with the lower joint 52 of the main board 20, a rectangular channel is formed for the insertion pin 26 to insert, so that the female maintenance plate 33 and the main board 20 form a firm connection, and at the same time, there is no space limitation during installation, which is convenient for the insertion pin 26 to insert.

[0082] According to an embodiment of the present application, when installing the maintenance plate 30, the installation space of the maintenance plate 30 is usually restricted by the already installed main board 20 around. The above design method can smoothly fill the maintenance plate 30 into the overall pavement slab step by step. Embodiment
