Description

Technical Field

[0001] The utility model relates to the technical field of slope construction, in particular to an anti-slip structure for a large-slope ski slope. Background Art

[0002] Large-slope ski resorts usually refer to ski slopes with relatively steep gradients, which are relatively large, generally about 20°, and some can reach 30° - 40°. The characteristics of such ski resorts are that the snow quality is relatively hard, mostly multi-level slopes, fan-shaped slopes, and large right-angled parallel slopes. In addition to skiing down, there are many turning skills, requiring participants to have a certain skiing foundation and sufficient physical strength to better adapt to the competition and challenges. Large-slope ski resorts are suitable for skiers who have passed the primary stage of practice, mastered the basic skiing methods and hope to further improve their skills. In the design of ski resorts, the large slope and the application of concrete on the slope are to provide different types of skiing experiences for skiers. The large slope is suitable for skiers who seek high speed and intense skiing, while the concrete on the slope provides more skill challenges and fun for skiers.

[0003] In the existing ski slope, there are anti-slip structures with several 200 - 700 mm convex concrete structure counterforts as the core, which have complex on-site construction, long construction period, and seriously affect traffic when setting counterforts on the slope surface of the ski slope. In addition, when setting anti-"Z" steel bars for anti-slip structures on the ski slope, under the action of external forces, the steel bars deform and slide, causing the thermal insulation structure layer to tear and heat bridge conduction, resulting in complex construction, high cost, and traffic problems. Summary of the Utility Model

A connecting plate is fixedly connected to the side of the mounting frame away from the structural steel bars. A first expansion bolt is provided on the connecting plate, and a second expansion bolt is provided on the mounting frame. Moisture-proof isolation expansion sleeves are provided at the bottoms of the first expansion bolt and the second expansion bolt.

[0006] Further preferably, a moisture-proof isolation layer is jointly provided between the first precast concrete and the mounting frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will further introduce the present utility model in detail Figures 1 to 2 with reference to the attached drawings.

[0018] An anti-slip structure for a large-slope ski slope, as Figure 1As shown in the figure, it is arranged on the surface of the first precast concrete 1 of the ski slope. An "L"-shaped mounting bracket 2 is arranged on the first precast concrete 1. A plurality of structural steel bars 3 are welded at equal intervals on one side of the mounting bracket 2. Further, the shape of the structural steel bar 3 is an isosceles triangle, and the distance between two structural steel bars 3 can be 50 cm. Further still, the structural steel bars 3 are subjected to moisture-proof and rust-proof treatment after welding. Specifically, spray coating treatment is adopted. A connecting plate 4 is fixedly connected to the side of the mounting bracket 2 away from the structural steel bars 3. A first expansion bolt 5 is arranged on the connecting plate 4. A second expansion bolt 7 is arranged on the mounting bracket 2. Moisture-proof isolation expansion sleeves 6 are arranged at the bottoms of the first expansion bolt 5 and the second expansion bolt 7. Further, the distance between the first expansion bolts 5 above the connecting plate 4 can be 50 cm. Specifically, the bottoms of the first expansion bolt 5 and the second expansion bolt 7 are conical, and high-elastic expansion tubes are arranged on the outer sides of the first expansion bolt 5 and the second expansion bolt 7. The first expansion bolt 5 and the second expansion bolt 7 are threadedly connected with the high-elastic expansion tubes, and the inside of the high-elastic expansion tube is internally conical. The moisture-proof isolation expansion tube 6 is sleeved inside the high-elastic expansion tube. When the first expansion bolt 5 and the second expansion bolt 7 are screwed in, the opening angle of the end of the high-elastic expansion tube can be changed.

[0019] Further, two groups of thorn claws are arranged in the middle and rear parts of the high-elastic expansion tube. Grooves are arranged at the connections between the thorn claws and the high-elastic expansion tube. The other ends of the thorn claws are provided with protruding corners inward. The outer sides of the thorn claws corresponding to the protruding corners are serrated friction surfaces. Shallow groove keys are engraved on the outer surfaces of the thorn claws between the serrated friction surfaces and the grooves. Further, the thorn claws are staggered and spaced at the middle and rear parts along the length direction of the high-elastic expansion tube and are alternately arranged along the circumferential direction. Further still, the outer surfaces of the shallow groove keys are provided with friction tooth patterns. The expansion angle at the bottom end of the high-elastic expansion tube is 0 to 30 degrees, and expansion is also achieved through the grooves. The other end of the first expansion bolt 5 opposite to the conical end is provided with a cup-shaped waterproof cap. A spring washer is arranged at the lower end of the cup-shaped waterproof cap. The end surface of the spring washer is provided with a staggered sharp angle thorn. A flat washer is arranged at the inlet end of the high-elastic expansion tube to evenly distribute the pressure of the nut on the connected parts. Further still, the problems that the existing expansion bolts cannot be reused multiple times and the exposed ends are too long, which is not conducive to construction safety, are solved.

[0020] Through the mutual cooperation among the mounting bracket 2, the structural steel bars 3 and the connecting plate 4, when forming the anti-slip structure of the concrete ski slope by pouring the ski slope, the height and width of the mounting bracket 2 can be customized according to the use requirements, so that the construction is simple during use, which is convenient for modularization and standardization during factory manufacturing. And through the mutual cooperation among the mounting bracket 2, the connecting plate 4, the first expansion bolt 5, the second expansion bolt 7, the high-elastic expansion tube and the moisture-proof isolation expansion tube 6, the installation is convenient and fast during installation, thereby effectively shortening the construction period and not affecting the on-site traffic.

[0021] Specifically, such as Figure 2As shown, a moisture-proof isolation layer 8 is jointly provided between the first precast concrete 1 and the mounting frame 2. Further, the moisture-proof isolation layer 8 is woven from a high-strength and high-elastic metal composite material, providing additional support and stability for the snow track, further enhancing the overall strength and stability of the snow track, and preventing slippage caused by foundation settlement or external forces.

[0022] Specifically, as Figure 2 shown, a moisture-proof isolation material layer 9 is filled inside the first precast concrete 1 near the mounting frame 2. The moisture-proof isolation material layer 9 is XPS. Further, XPS is an extruded polystyrene insulation board, which has a continuous and uniform surface layer and a closed-cell honeycomb structure. As a result, XPS has excellent thermal insulation performance and compressive strength, and the thermal conductivity of XPS is low, only 0.028W / M.K, providing a good thermal insulation effect. Furthermore, XPS also has the characteristics of light weight, moisture-proof, anti-corrosion, and non-volatile. The XPS material is mainly used as a building insulation material, providing excellent thermal insulation and compressive performance.

[0023] Specifically, as Figure 2 shown, the top extension end of the structural steel bar 3 is fixedly connected to the bottom of the second precast concrete 10, and the bottom of the mortar layer 11 is arranged on the upper part of the moisture-proof isolation material layer 9, further improving the installation stability of the mounting frame 2.

[0024] Further, by setting the second precast concrete 10, the mortar layer 11, and the top extension end of the structural steel bar 3 fixedly connected to the bottom of the second precast concrete 10, and combining the moisture-proof isolation layer 8 and the moisture-proof isolation material layer 9, an efficient, stable, and durable anti-slip structure layer is constructed, further significantly improving the anti-slip performance and safety of the snow track, and effectively increasing the service life of the snow track, providing a better sliding experience for skiers.

[0025] Further, a main cable 13, a deformation sensor 14, a humidity sensor 15, a pressure sensor 16, and a temperature sensor 12 are respectively arranged inside the structural steel bar 3, and the deformation sensor 14, the humidity sensor 15, the pressure sensor 16, and the temperature sensor 12 are respectively connected to the branch cables of the main cable 13. Specifically, the main cable 13, the deformation sensor 14, the humidity sensor 15, the pressure sensor 16, and the temperature sensor 12 are all installed on the mounting frame 2 and the structural steel bar 3. Specifically, the deformation sensor 14 is used to monitor the bending, compression, or tension of the first precast concrete 1, and the humidity sensor 15, the pressure sensor 16, and the temperature sensor 12 all monitor the humidity, pressure, and temperature of the first precast concrete 1, and the monitored data is converged through the branch cables to the main cable 13 and connected to the controller and recorder in the main monitoring room.

[0026] Working principle

[0027] Before use, the structural steel bars 3 are treated for moisture and rust prevention after welding. During installation, the prefabricated mounting frame 2 is placed inside the first precast concrete 1, and a moisture-proof isolation layer 8 is laid on the upper part of the first precast concrete 1. Installation holes are drilled in the moisture-proof isolation layer 8. The mounting frame 2 is placed on the moisture-proof isolation layer 8. The mounting frame 2 and the connecting plate 4 are installed inside the moisture-proof isolation sleeve 6 through the first expansion bolts 5, the second expansion bolts 7 and the highly elastic expansion tubes. The moisture-proof isolation sleeve 6 is inserted into the installation holes. When installing, use a hammer to strike the outer end of the highly elastic expansion tube so that its end is close to the inside of the installation hole, and then fix the mounting frame 2 and the connecting plate 4 on the upper part of the moisture-proof isolation layer 8 through the spring washers and flat washers respectively with multiple first expansion bolts 5 and second expansion bolts 7. At this time, rotating the first expansion bolts 5 and the second expansion bolts 7 can change the opening angle of the end of the highly elastic expansion tube. Subsequently, the triangular cavity of the mounting frame 2 is filled with a moisture-proof isolation material layer 9. Then, the deformation sensor 14, the humidity sensor 15, the pressure sensor 16 and the temperature sensor 12 are placed inside the moisture-proof isolation material layer 9. The deformation sensor 14 is used to monitor the bending, compression or tension of the first precast concrete 1. The humidity sensor 15, the pressure sensor 16 and the temperature sensor 12 all monitor the humidity, pressure and temperature of the base 1, and transmit the monitored data to the controller and recorder in the general monitoring room through the branch cables converging to the main cable 13. Finally, a mortar layer 11 and a second precast concrete 10 are laid successively on the upper part of the mounting frame 2 to form a non-slip structure for the concrete ski slope.

Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as they are within the protection scope of the utility model, they are protected by the patent law.
