Description

Technical Field

[0002] The smoothness of traffic roads and the flatness of the road surface have a profound impact on the performance of transportation tools. When the road surface is partially damaged or the entire road section is interrupted, it is necessary to use road panels for paving when rapid construction or repair is required. There are two types of existing road panels: cast-in-place concrete road panels and prefabricated road panels. Cast-in-place concrete road panels cannot meet the requirements of rapid construction and need to solidify for a period of time after paving before they can be used. Existing prefabricated road panels often require additional treatment of the foundation before paving to make them meet the bearing capacity requirements. Moreover, the existing prefabricated road panels require specially set connecting keys to ensure that the road panels are tightly connected. The manufacturing of the road panels is complex, the manufacturing precision requirements are high, and the cost is high, which is not conducive to large-scale promotion.

[0032] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0033] Example 1

[0034] A double-layer composite road panel for rapid paving includes an upper plate and a lower plate, wherein the upper plate includes an upper plate mold and a concrete filler, and the lower plate includes a lower plate mold and a concrete filler, wherein the upper plate mold and the lower plate mold have the same size and are both regular hexagons; the outer contours of the lower plate mold and the upper plate mold are regular hexagons, and the interior is set as a hollow cavity for filling concrete. Specifically, one side of the lower plate mold and the upper plate mold is a cover plate, and the other side is a regular hexagonal frame, with a hollow setting in the middle; an embedded sleeve is provided at the center of the regular triangle with the center of the lower plate mold as the vertex and the side of the hexagon as the base; positioning tubes are provided at the vertex corners of two adjacent sides of the lower plate mold; the positioning plate is used to align the three vertex corners of every three lower plates together and fix them through three positioning pins. Specifically, the structural schematic diagram of the lower plate mold is as shown in Figure 1 As shown, the lower plate mold consists of a cover plate 1, an outer ring connecting plate 2, radial T ribs 3, an inner ring plate 4, a positioning tube 5 and an embedded sleeve 6. The outer ring connecting plate 2 is fixedly connected to the cover plate to form a hexagonal frame with a cavity in the center. The inner ring plate 4 is connected to the outer ring connecting plate 2 and folded to the center of the other surface of the lower plate to form a cavity as a whole. The radial T rib 3 connects the diagonal of the hexagonal frame. The radial T rib is a "T"-shaped structure, one side of the "T" shape is parallel to one side of the cover plate and is horizontally arranged, and the two ends of the vertical side are fixedly connected to the two adjacent angles on the inner side of the outer ring connecting plate. The positioning tube 5 is set at the center of the radial T rib 3 at the angle of the two adjacent sides, and the 6 embedded sleeves are evenly distributed and fixed on the cover plate.

[0035] like Figure 2 As shown, the upper plate mold includes a cover plate 1, an outer ring connecting plate 2, radial T ribs 3, an inner ring plate 4 and an embedded sleeve 6. The cover plate is a regular hexagon, and its area is the same as that of the cover plate of the lower plate mold. The outer ring connecting plate is fixedly connected to the cover plate around the edge of the cover plate to form a hexagonal frame. The other structures are the same as those of the lower plate mold. The inner ring plate connects the outer ring connecting plate and folds to the center of the other side of the lower plate, forming a cavity as a whole; the radial T rib is the diagonal connecting the hexagonal frame, and the embedded sleeve is fixed on the cover plate. Among them, the side length of the regular hexagon can be set to 20 to 200 cm according to the application scenario. The material of the lower plate mold and the upper plate mold can be metal materials such as stainless steel or aluminum alloy, or lightweight, high-strength and corrosion-resistant composite materials such as basalt fiber.

[0036] When in use, the lower plate mold and the upper plate mold are filled with concrete 8 and smoothed to form a lower plate (such as Figure 3 as shown) and the upper plate (as Figure 4 As shown), proceed with the installation as follows:

[0037] The first step is to prepare the foundation so that its flatness and bearing capacity meet the design requirements.

[0038] Step 2: Lay the lower slab flat on the foundation with the cover facing downward and the concrete facing upward. During the laying process, adjust the lower slab so that the positioning pins can connect the positioning plate and every three adjacent lower slabs together to ensure that the lower slab is laid accurately. Figure 5 As shown, the positioning plate 7 is provided with three branch structures, the outer edge of each branch is set as a circular ear, a through hole corresponding to the positioning hole is opened on the circular ear, and a handle is also provided on the positioning plate for easy operation. The circular ear can effectively prevent injuries to personnel during construction.

[0039] The third step is to lay the upper boards after the lower boards are laid. Each upper board has the same area as the lower boards, and the upper boards are laid one by one from the middle to the surrounding areas. First, remove the positioning plate and positioning pins in the middle of the laid lower boards to ensure that a single upper board can be laid on the lower boards. Each upper board should be evenly distributed on the three lower boards to form a "staggered overlap", and install the fixing pins between the upper and lower boards. The fixing pins are inserted into the embedded sleeves 6 that align the upper and lower boards, such as Figure 6 shown.

[0040] Step 4. Continue to remove the positioning plates and positioning pins that interfere with the second upper plate, and lay the second upper plate; follow this method to lay the third upper plate, the fourth upper plate, and so on in turn until the upper plates are laid; the positioning plates and positioning pins that do not interfere with the upper plates are still installed on the lower plates.

[0041] The use of the above-mentioned double-layer composite road panel can achieve rapid paving, and has high material utilization, light weight, simple manufacturing, low cost, convenient construction and maintenance, rapid assembly, low requirements for foundation bearing capacity, and is conducive to large-scale promotion. When used, through "staggered overlap" and the fixing pins connecting the upper and lower panels, the upper and lower composite panels are closely fitted to form a whole, and the area where the load of the vehicle is transferred to the foundation is larger, the bearing capacity requirements for the foundation are lower, and the overall performance after assembly is good.

[0042] The above is only a preferred embodiment of the utility model, and does not limit the utility model in other forms. Any person skilled in the art can use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
