Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a modular road panel. Background Art

[0002] In civil engineering projects such as roads, buildings, and municipalities, temporary roads are often required to facilitate the smooth passage of construction vehicles. Modular road panels are a common method for paving temporary roads. They consist of multiple independent, interchangeable modules that can be spliced together as needed to form single or dual lanes or temporary areas to accommodate vehicle traffic and cargo loading and unloading.

[0003] The existing technology has the following deficiencies: The prior art application number 201420669736.3 states that “a modular road panel for construction” “includes a pavement unit, a single ear, a double ear, and a latch. The pavement unit is a closed box-shaped structure. The single ear, the double ear, and the latch are used to connect the pavement unit and are arranged around the pavement unit.”

[0004] The above-mentioned equipment has the advantages of high modularity, simple assembly and reuse by setting single ears, double ears, latches, etc. The modular road panel is damaged or severely grooved when the top is crushed by vehicles during use, which will affect its normal use and needs to be replaced. The above-mentioned equipment often requires the replacement of the damaged road panel as a whole, which easily leads to waste of resources. In addition, the above-mentioned equipment is often crushed by heavy vehicles such as large trucks and is easily broken due to the influence of excessive gravity, affecting normal use. The bearing strength of the equipment can be further improved. Utility Model Content

[0025] The reinforcement assembly 8 includes a cavity 801, a first reinforcement 802 and a second reinforcement 803. A cavity 801 is opened in the first road panel 1, and a first reinforcement 802 and a second reinforcement 803 are arranged in the cavity 801. The first reinforcement 802 and the corresponding second reinforcement 803 can offset each other's impact force.

[0026] In this embodiment, the first road panel 1 and the second road panel 2 are both square in shape as a whole, and the center positions of the four sides of the first road panel 1 are fixedly mounted with a clamping block 3;

[0027] Specifically, the square design of the first road panel 1 and the second road panel 2 can facilitate splicing at any angle between the two;

[0028] In this embodiment, a card slot 4 is provided at the center of each of the four sides of the second road panel 2. The card slot 4 is adapted to the card block 3, and there is a card connection between the card block 3 and the card slot 4.

[0029] Specifically, the card block 3 combined with the card slot 4 can facilitate the splicing between the first road panel 1 and the second road panel 2;

[0030] In this embodiment, the center positions of the four sides of the first replacement plate 5 are fixedly mounted with connecting blocks 7. The first replacement plate 5 has the same overall size as the first road panel 1, but the thickness of the first replacement plate 5 is smaller than that of the first road panel 1. The first replacement plate 5 is placed on top of the first road panel 1.

[0031] Specifically, the connecting block 7 can facilitate the connection between the first replacement plate 5 and the first road panel 1;

[0032] In this embodiment, the second replacement plate 6 has the same overall size as the second road panel 2, but the thickness of the second replacement plate 6 is smaller than that of the second road panel 2. The second replacement plate 6 is placed on top of the second road panel 2, and the four groups of slots 4 on the second road panel 2 pass through the second replacement plate 6.

[0033] Specifically, when the first road panel 1 and the second road panel 2 are in use, the parts rolled over by vehicles are the first replacement panels 5 and the second replacement panels 6 rather than the tops of the first road panel 1 and the second road panel 2. If the first replacement panels 5 and the second replacement panels 6 are rolled over by vehicles for a long time, they may be damaged or severely deformed by grooves. In this case, only the first replacement panels 5 and the second replacement panels 6 need to be replaced, without replacing the entire first road panel 1 and the second road panel 2.

[0034] In this embodiment, the bolt holes 10 on the four groups of connecting blocks 7 all pass through the corresponding clamping blocks 3, and the four corners of the top of the second replacement plate 6 are provided with placement slots 9 and bolt holes 10. The four groups of bolt holes 10 all pass through the second road panel 2. The bolt holes 10 are adapted to the fixing bolts 11. The connecting block 7 and the clamping block 3, and the second replacement plate 6 and the second road panel 2 are fixed by fixing bolts 11. After the fixing bolts 11 are installed, their top ends are completely located in the corresponding placement slots 9.

[0035] Specifically, the placement groove 9 can facilitate the placement of the top of the fixing bolt 11, and can prevent the fixing bolt 11 from protruding from the top of the road panel and affecting the surface smoothness of the road panel;

[0036] In this embodiment, a plurality of first reinforcement members 802 and a plurality of second reinforcement members 803 are fixedly installed on the bottom and the top of the inner wall of the reinforcement assembly 8, respectively. The first reinforcement members 802 and the second reinforcement members 803 are both semicircular in shape as a whole and their lengths are consistent with the length of the cavity 801. The first reinforcement members 802 and the second reinforcement members 803 are both made of metal and are consistent in number and symmetrically arranged. The protruding end of each group of first reinforcement members 802 is in contact with the protruding end of the corresponding second reinforcement member 803. The reinforcement assembly 8 is provided in both the second road panel 2 and the first road panel 1.

[0037] Specifically, the cavity 801 can facilitate the installation of the first reinforcement member 802 and the second reinforcement member 803 .

[0038] The working principle and use process of the present invention are as follows: the number of the first road panel 1 and the second road panel 2 is not limited to one group. Several groups of the first road panel 1 and the second road panel 2 are laid on the ground and the clamping blocks 3 and the clamping slots 4 are clamped together. The clamping blocks 3 and the clamping slots 4 can be used to modularly splice several groups of the first road panel 1 and the second road panel 2. Since modular road panels are already mature equipment, their use principles and related components are well known or can be found by professionals in the relevant technical field of the present invention, so they are not described here.

[0039] After the installation of several groups of first road panels 1 and second road panels 2 is completed, several groups of first replacement panels 5 and second replacement panels 6 are laid on the top of several groups of first road panels 1 and second road panels 2 respectively, and fixed by fixing bolts 11. At this time, the top of the fixing bolt 11 is completely located in the placement groove 9, which can prevent the fixing bolt 11 from protruding from the top of the road panel and affecting the surface smoothness of the road panel. When the modular road panel is in use, the vehicle rolls over the first replacement panel 5 and the second replacement panel 6 instead of the top of the first road panel 1 and the second road panel 2. After the vehicle rolls over for a long time, the first replacement panel 5 and the second replacement panel 6 will be damaged or seriously deformed. Only the first replacement panel 5 and the second replacement panel 6 need to be replaced, and there is no need to replace the first road panel 1 and the second road panel 2 as a whole, which can reduce resource waste.

[0040] Since the first reinforcement 802 and the second reinforcement 803 are made of metal and both are semi-circular in shape with their protruding ends touching each other, the metal material has a certain resilience after being semi-circular, which makes the first reinforcement 802 and the second reinforcement 803 as a whole have a certain resilience. Several groups of first reinforcements 802 and corresponding second reinforcements 803 can offset each other's impact force from heavy vehicles, thereby improving the overall bearing strength of the road panel.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
