Description

Technical Field

[0001] The invention relates to the technical field of road panel installation, and in particular to a wear-resistant assembled road panel and a construction method thereof. Background Art

[0002] At present, my country's airports mainly use cast-in-place cement concrete pavement. The construction of cast-in-place pavement surface mainly includes a series of processes such as formwork production and support, mixture mixing, ingredient transportation, paving, mixture vibration, leveling and slurry, surface finishing, surface roughening, curing, grooving, cutting, expanding, cleaning, and filling. Due to the influence of human factors, environmental changes, and low process technology requirements, there are many construction restrictions, long cycles, high energy consumption, high pollution, large quality discreteness, and poor durability. In addition, the maintenance is difficult, the cycle is long, the cost is high, and the technical economy of the whole life cycle is low. The prefabricated concrete pavement panel is prefabricated in advance in the factory, with a stable production environment, reliable quality, and good durability.

[0003] However, the existing road panels consume a lot of manpower during installation, positioning and leveling, and need to frequently use large-scale lifting equipment. People and machines work at the same time, which is prone to danger. Therefore, the present invention is proposed. Summary of the invention

[0004] The present application provides a wear-resistant assembled road panel and a construction method thereof to solve the problem of inconvenient installation, positioning and leveling of the road panel.

[0005] In order to solve the above technical problems, the present application provides a wear-resistant assembled road panel, comprising: a plate body, an upper steel bar frame arranged in the plate body, and a lower steel bar frame arranged at the bottom of the upper steel bar frame; characterized in that a first tongue and groove is arranged at one end of the plate body, and a second tongue and groove is arranged at the other end of the plate body, the first tongue and groove extend into the second tongue and groove to form a splicing end, and both sides of the splicing end are provided with reserved grooves at the outer end of the plate body, and a leveling mechanism is arranged in the reserved groove; The leveling mechanism includes an upper adjusting plate attached to the top of the reserved groove, a lower adjusting plate attached to the ground, and a double-threaded sleeve arranged between the upper adjusting plate and the lower adjusting plate. An upper screw is arranged at the bottom of the upper adjusting plate, and a lower screw is arranged at the top of the lower adjusting plate. Both the upper screw and the lower screw extend into the double-threaded sleeve.

[0006] In some embodiments of the present application, the surface of the plate is sprinkled with corundum, and the corundum is added when the concrete on the plate is initially set.

[0007] In some embodiments of the present application, a heating sleeve is pre-buried between the upper steel frame and the lower steel frame along the width direction of the plate body, and the outer surface of the heating sleeve is provided with a spiral groove, and a heating wire is embedded in the spiral groove, and the heating wire is used to increase the surface temperature of the plate body.

[0008] In some embodiments of the present application, a first U-shaped plate is vertically arranged on one side of the upper adjustment plate close to the plate body, and a second U-shaped plate is vertically arranged on one side of the lower adjustment plate close to the plate body. The first U-shaped plate and the second U-shaped plate are staggered for positioning the upper adjustment plate and the lower adjustment plate.

[0009] In some embodiments of the present application, the first U-shaped plate and the second U-shaped plate are attached to the side surfaces of the plate body.

[0010] In some embodiments of the present application, the upper screw rod is welded and fixed to the bottom surface of the upper adjustment plate, and the lower screw rod is welded and fixed to the top surface of the lower adjustment plate.

[0011] In some embodiments of the present application, the length of the double-threaded sleeve is 12 cm. When the double-threaded sleeve is screwed to one side, the upper screw and the lower screw approach each other, and the height of the plate body decreases; when the double-threaded sleeve is screwed to the other side, the upper screw and the lower screw move away from each other, and the height of the plate body increases.

[0012] In some embodiments of the present application, the first tongue and the second tongue are arranged alternately up and down, and the first tongue and the second tongue of adjacent plates are arranged opposite to each other.

[0013] In some embodiments of the present application, a construction method of a wear-resistant assembled road panel is provided, and the specific steps of the method are as follows: Step 1: clean the location to be laid, mark the installation location of the first board, arrange a positioning frame at the installation location of the first board, and place the board in the positioning frame using a lifting device; Step 2: placing a positioning frame at an adjacent position of the first plate, and placing the adjacent plate in the positioning frame again using the hoisting equipment. When placing the adjacent plate, the first tongue and the second tongue are arranged opposite to each other, so that the adjacent plate can be quickly positioned; Step three, after determining the installation height of the first plate, rotate the double-threaded sleeve according to the height difference between adjacent plates to adjust the height of adjacent plates so that the first tongue and the second tongue fit together, thus completing the installation of adjacent plates.

[0014] Compared with the prior art, the present invention has the following characteristics and beneficial effects: The present invention realizes rapid and accurate positioning of adjacent plates by setting the first tongue and the second tongue in cooperation with the installation frame of the plate, improves the wear resistance of the plate surface by setting diamond abrasive on the surface of the plate, stabilizes the plate structure by setting a multi-layer steel bar frame, and can level the plate without the aid of large-scale lifting equipment by setting a leveling mechanism, thereby saving resources and improving construction safety. The plate can automatically heat up and has a good performance in melting snow in winter. The present invention has high construction efficiency and strong wear resistance, and can produce better results by promoting its use. BRIEF DESCRIPTION OF THE DRAWINGS
