Description

Technical Field

[0001] The utility model relates to the technical field of road surface structures, in particular to a road surface heat conduction groove structure for installing a heating belt. Background Technique

[0002] With the global climate warming, extreme weather events occur frequently, and the phenomena of road icing and snow accumulation in winter are becoming increasingly serious, bringing great inconvenience and potential safety hazards to traffic. Traditional snow melting and ice removing methods, such as salting and snow shoveling, are not only inefficient, but also cause certain damage to the environment and the road itself. In recent years, with the continuous development of material science and engineering technology, some new high thermal conductivity materials have been gradually introduced into the road surface structure design. These materials usually have excellent thermal conductivity and stability, and can significantly improve the heat conduction efficiency of the road surface. At the same time, through reasonable structural design and construction technology, these high thermal conductivity materials can be effectively integrated into the road surface structure to form a road surface system with good thermal conductivity.

[0003] Chinese Patent Publication No. CN108442208B discloses a road surface structure with good thermal conductivity, including a roadbed at the bottom, a lime-fly ash soil base layer laid on the roadbed, an asphalt concrete lower surface layer laid on the lime-fly ash soil base layer, an asphalt concrete middle surface layer laid on the asphalt concrete lower surface layer, a heating layer laid on the asphalt concrete middle surface layer, and an asphalt concrete upper surface layer laid on the heating layer. The heating layer includes a heat insulation adhesive layer, an electric heating film layer, and a heat conduction adhesive layer. The electric heating film layer is located between the heat insulation adhesive layer and the heat conduction adhesive layer. The heat insulation adhesive layer is bonded to the asphalt concrete middle surface layer, and the heat conduction adhesive layer is bonded to the asphalt concrete upper surface layer. The road surface structure with good thermal conductivity of this invention can better remove snow and ice on the road surface in time without affecting road traffic. However, this kind of heat-conducting road surface does not have a expansion joint structure and cannot effectively prevent the problems of thermal expansion and contraction generated during the heating process.

[0004] Chinese Patent Publication No. CN213086503 discloses a heat - generating road surface, including: a road surface layer containing heating elements therein; a bonding layer located below the road surface layer and connected to the road surface layer; a bracket having a supporting surface and at least two supporting feet, the supporting feet being connected to the supporting surface, the bracket being located below the bonding layer, the supporting surface of the bracket being connected to the road surface layer through the bonding layer, at least one chamber being formed in the bracket, and a heat - insulating layer being provided in the chamber and attached to the inner surface of the supporting surface. This heat - generating road surface has a simple structure, is convenient for paving and maintenance, has a low cost, and at the same time has a good snow - melting effect, solving the problems of the existing self - melting snow road surface with a complicated structure, inconvenient maintenance, and poor snow - melting effect. However, the road surface layer (the outermost layer) of this heat - generating road surface does not have a buffer structure. When passing pedestrians and vehicles, the heating elements are easily subjected to large pressures and thus damaged. Summary of the Utility Model

[0005] Therefore, in view of the above problems, the present utility model provides a road surface heat - conducting groove structure for installing a heating belt, which solves the problems that the existing heat - generating road surface is prone to cracking when thermal expansion and contraction occur, and the heating elements are easily subjected to large pressures and thus damaged.

[0006] To achieve the above object, the present utility model adopts the following technical solutions:

[0007] A road surface heat - conducting groove structure for installing a heating belt, including a heat - conducting groove main body, characterized in that the heat - conducting groove main body includes a pair of mirror - symmetrically arranged profiled steels and a cover - joint plate. The pair of profiled steels includes a left profiled steel and a right profiled steel. The cover - joint plate connects the left profiled steel and the right profiled steel. A noise - reducing plate is further provided at the upper ends of the pair of profiled steels. The pair of profiled steels, the cover - joint plate and the noise - reducing plate enclose a receiving groove. At least one partition is provided inside the receiving groove. First grooves are provided on the side walls of both sides of the receiving groove, and second grooves are provided on the side walls of the partition. A heating belt is installed in the receiving groove. A first elastic filling layer is provided on the outer side of the bottom of the heating belt, and a second elastic filling layer is provided on the outer side of the top of the heating belt. A heat - conducting layer is provided on the second elastic filling layer. A first anchoring device is provided at the lower end of the left profiled steel. The first anchoring device includes a first cushion block and at least one first anchoring screw. A second anchoring device is provided at the lower end of the right profiled steel. The second anchoring device includes a second cushion block and at least one second anchoring screw. The first anchoring screw penetrates through the first cushion block and the lower end of the left profiled steel, and the second anchoring screw penetrates through the second cushion block and the lower end of the right profiled steel.

[0008] Further, the cover - joint plate is of a U - shaped structure.

[0009] Further, the first elastic filling layer and the second elastic filling layer are tightly connected to the inner wall of the receiving groove.

[0010] Furthermore, the cross-section of the left steel section is E-shaped.

[0011] Furthermore, the noise reduction plate is a detachable structure.

[0012] Furthermore, the noise reduction plate is of I-shaped structure.

[0013] Furthermore, the noise reduction plate is made of aluminum sound-absorbing material.

[0014] Furthermore, the heat conduction layer is made of high heat conduction metal material.

[0015] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0016] The road surface heat conduction groove of the present utility model includes a heat conduction groove main body, and the heat conduction groove main body includes a pair of mirror-symmetrically arranged steel sections and a joint covering plate. The pair of steel sections includes a left steel section and a right steel section, and there is a gap between the left steel section and the right steel section. The joint covering plate connects the left steel section and the right steel section, enabling horizontal expansion and contraction between the left steel section and the right steel section in the width direction, thereby forming an expansion joint structure, avoiding stress and deformation when the heat conduction groove main body expands or contracts due to temperature influence, and thus avoiding damage to the heat conduction groove structure; moreover, the heat conduction groove structure made of steel can directly bear the wheel load, has a certain vertical stiffness, and has the advantage of smooth driving.

[0017] A noise reduction plate is arranged at the upper end of the pair of steel sections. The noise reduction plate can effectively absorb the noise generated when vehicles pass by, thereby reducing the noise and avoiding affecting the surrounding residents; at the same time, it can also isolate left and right, preventing substances such as stones, gravel, and dust from entering the accommodation groove.

[0018] A first elastic filling layer is arranged on the outer side of the bottom of the heating belt, and a second elastic filling layer is arranged on the outer side of the top of the heating belt. The first elastic filling layer and the second elastic filling layer are tightly connected to the inner wall of the accommodation groove to form a buffer structure, which can reduce the vibration generated when the vehicle passes by, avoid mutual friction with the inner wall of the accommodation groove and cause damage to the heating belt, thereby effectively protecting the heating belt; at the same time, it can improve the strength, crack resistance and compressive capacity of the concrete.

[0019] A heat conduction layer is arranged on the second elastic filling layer. The heat conduction layer is made of high heat conduction metal material, which can quickly transfer the heat generated by the heating belt upward to the road surface to achieve ice melting and snow removal, further improving the heat transfer efficiency between the heat conduction layer and the road surface. At the same time, it can also increase the firmness between the heat conduction layer and the road surface, enabling it to bear greater pressure.

[0020] At least one partition is arranged inside the accommodation groove, which can install multiple heating belts at the same time to improve the heating efficiency.

[0021] On both side walls of the accommodation groove, there are first grooves, and on the side wall of the partition board, there are second grooves. The first grooves and the second grooves can match the protrusions on the side wall of the heating belt, playing a role in fixing the heating belt and preventing the heating belt from shifting during use.

[0022] At the lower end of the left steel section, there is a first anchoring device, and at the lower end of the right steel section, there is a second anchoring device, which can connect the heat conduction groove structure to the concrete road surface and maintain the stability and safety of the heat conduction groove structure.
