Description

Technical Field

[0001] This invention relates to the field of ski track technology, and more particularly to a support system for ski tracks. Background Technology

[0002] A ski slope is a curved, extended concrete track with internal cooling pipes to maintain a stable low temperature for the surface snow and ice. These tracks are often built in mountainous areas, utilizing the terrain to create their winding course, allowing skiers to use the slope to perform maneuvers such as dives and turns. However, due to the difference in elevation between the natural terrain and the standard track shape, concrete pillars are typically installed underneath the track for support.

[0003] The existing reinforced concrete columns are anchored to the track floor slab below and the track concrete above via central pillars. Furthermore, the reinforced concrete columns are separated from both the track floor slab and the track concrete by rubber supports, ensuring that the reinforced concrete columns do not directly contact the track concrete. When these swaying columns are used in bobsleigh and luge tracks, their lateral stiffness is relatively low, causing slight displacement of the track due to upper loads. This displacement can be self-adjusted by the elastic rubber, which also provides a shock absorption effect.

[0004] However, the properties of rubber are greatly affected by temperature. Between the glass transition temperature and the brittle temperature, rubber is in a glassy state, where rubber molecules can only vibrate in situ, and the deformation is extremely limited. Between the glass transition temperature and the viscous flow temperature, rubber is in a highly elastic state, undergoing elastic deformation when subjected to external forces. When the external temperature rises to the viscous flow temperature, the rubber transitions from the highly elastic state to the viscous flow state, and irreversible plastic deformation occurs when the rubber is subjected to external forces.

[0005] In other words, in order to maintain the stable performance of elastic rubber pads, the ambient temperature needs to be kept neither too high nor too low. However, ski tracks are mostly built in cold and temperate regions, where the cold winters and hot summers will affect the performance of the rubber. Moreover, once plastic deformation occurs, it cannot be reversed, resulting in high track maintenance and repair costs and reducing the track's lifespan.

[0006] Furthermore, during track use, it is susceptible to repeated impacts, and since many tracks are built in mountainous areas, they are subject to significant wind loads. Over time, the support columns are prone to tilting, altering the slope of the upper track surface, affecting normal track use, and posing safety hazards. Therefore, it is necessary to further improve the tightness between the concrete support columns and the track structure and concrete base slab. Summary of the Invention

[0007] Based on the above analysis, the present invention aims to provide a support system for ski tracks to solve the problems of poor flexibility and time-consuming and labor-intensive track maintenance in existing ski and sled tracks.

[0008] The objective of this invention is mainly achieved through the following technical solutions:

[0009] A support system for a ski track includes: a track shear wall and track support columns, wherein the track shear wall and track support columns are disposed between track concrete and base concrete to support the track; the track support columns include: a first central support column, a first concrete column, and a rubber pad, wherein the rubber pad is disposed between the first concrete column and the track concrete; the track shear wall includes: a second central support column, a second concrete column, and a crossbeam, wherein the second concrete column is cast outside the second central support column, and the crossbeam connects the two second concrete columns of the track shear wall and the track concrete.

[0010] Furthermore, the shear walls of multiple tracks are set at equal intervals, with the distance between the shear walls of adjacent tracks being 30 to 50 meters.

[0011] Furthermore, multiple sets of track support columns are installed between the shear walls of adjacent tracks; the spacing between two sets of track support columns is 2 to 5 meters.

[0012] Furthermore, the distance between the track shear wall and the track support column is 2 to 3 meters.

[0013] Furthermore, the first central support column is connected to the track concrete via an upper fixing plate.

[0014] Furthermore, a shear wall fixing plate is fixedly installed at the upper end of the second central support column, and the shear wall fixing plate is fixedly connected to the track concrete.

[0015] Furthermore, the track support column also includes a rubber pad.

[0016] Furthermore, the rubber pad is a spliced ​​structure composed of multiple fan-shaped parts.

[0017] Furthermore, a protrusion is provided on the track support column, and a sleeve is nested in the protrusion.

[0018] Furthermore, a bolt is installed in the sleeve, and the height of the bolt extending out of the protrusion is less than the thickness of the rubber pad.

[0019] The bolt extends from the upper surface of the protrusion and is used to limit the rubber pad.

[0020] Furthermore, a lower fixing plate is fixedly installed at the lower end of the first central support column, and the lower fixing plate is fixedly connected to the base concrete.

[0021] Furthermore, multiple tie rods are vertically arranged on the lower fixing plate.

[0022] Furthermore, the tie rod is a cylindrical support rod;

[0023] Alternatively, the tie rod can be a corrugated support rod;

[0024] Alternatively, the brace may be a barbed rod.

[0025] Furthermore, an upper fixing plate is fixedly installed at the upper end of the first central support column of the track support column, and the upper fixing plate is fixedly connected to the track concrete.

[0026] Specifically, both the upper fixing plate and the shear wall fixing plate are corrugated plates.

[0027] Furthermore, a protective cover is provided over the rubber pad; a temperature control lamp is installed on the protective cover.

[0028] The technical solution of the present invention can achieve at least one of the following effects:

[0029] 1. The track support system of the present invention uses track shear walls as rigid supports for the main body of the track, namely the track concrete, while track support columns with rubber pads installed on top provide flexible support for the track concrete. The track support system of the present invention achieves support for the track concrete through the cooperation of track shear walls and track support columns. This combination of rigid and flexible support improves the impact resistance and overall stability of the track while ensuring reliable support for the track concrete.

[0030] 2. The track support system of the present invention adopts a portal structure composed of double concrete columns and beams as the track shear wall. The track shear wall is cast as a whole with the track concrete, which makes the support system more stable in connection with the track body. The portal structure track shear wall serves as a rigid support for the track concrete, ensuring the overall stability of the track.

[0031] 3. The track support system of the present invention sets multiple sets of track support columns as flexible supports between two adjacent sets of track shear walls. Compared with the track shear walls, rubber pads are set between the concrete columns of the track support columns and the track concrete for vibration isolation and buffering. When the track is put into use, the flexible track support columns can allow the track body to undergo slight deformation, and the rubber pads can buffer the rigid impact between the track concrete and the concrete columns, ensuring the track's ductility and seismic performance.

[0032] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0047] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0048] Example 1

[0049] A specific embodiment of the present invention discloses a support system for a ski track, comprising: a track shear wall and track support columns, wherein the track shear wall and track support columns are disposed between track concrete 1 and base concrete 4 for supporting the track; the track shear wall includes two second central support columns 14 and a crossbeam 12, and a second concrete column 15 is cast outside the second central support columns 14; the crossbeam 12 connects the two second concrete columns 15 of the track shear wall and the track concrete 1; the track support column includes a first central support column 3, a first concrete column 2, and a rubber pad 6; the rubber pad 6 is disposed between the first concrete column 2 and the track concrete 1; and multiple sets of track support columns are disposed between adjacent track shear walls, such as... Figure 1 As shown.

[0050] In one specific embodiment of the present invention, multiple track shear walls are arranged at equal intervals, with the distance between adjacent track shear walls being 30 to 50 meters; the distance between adjacent track support columns being 2 to 5 meters; and the distance between the track shear walls and track support columns being 2 to 3 meters.

[0051] Preferably, the distance between two adjacent track shear walls is 35 meters; the distance between the track shear walls and the track support columns is 2.5 meters; and the distance between two adjacent sets of track support columns is 2.5 meters. Further, 13 sets of track support columns are installed between two track shear walls.

[0052] Regarding the support method of the track support system of this invention:

[0053] 1) The upper part of the track support system of the present invention is fixedly connected to the track concrete 1.

[0054] I. Such as Figure 2As shown, the connection method between the track shear wall and the track concrete 1 is as follows:

[0055] In one specific embodiment of the present invention, shear wall fixing plates 13 are fixedly installed at the upper ends of the two second central support columns 14 of the track shear wall, and the shear wall fixing plates 13 are fixedly connected to the track concrete 1. Specifically, the shear wall fixing plates 13 are cast inside the track concrete 1 and are fixed to the second central support columns 14 on both sides by welding.

[0056] The second concrete column 15 and the crossbeam 12 of the track shear wall are integrally cast. The two second concrete columns 15 and the crossbeam 12 of the track shear wall form a portal structure, and the portal structure of the track shear wall is integrally cast with the track concrete 1.

[0057] II. As Figure 3 As shown, the connection method between the track support column and the track concrete 1 is as follows:

[0058] An upper fixing plate 5 is fixedly installed at the upper end of the first central support column 3 of the track support column, and the upper fixing plate 5 is fixedly connected to the track concrete 1. Specifically, the upper fixing plate 5 is cast inside the track concrete 1 and is fixed to the first central support column 3 of the track support column by welding, such as... Figure 3 As shown.

[0059] Furthermore, such as Figure 2 , Figure 3 As shown, both the shear wall fixing plate 13 and the upper fixing plate 5 adopt a corrugated plate structure.

[0060] The corrugated structure used in this invention has better buckling performance than the flat plate structure.

[0061] When the track is in use, it will undergo slight bending deformation under the impact of movement. Since both the shear wall fixing plate 13 and the upper fixing plate 5 are corrugated metal plates, they can follow the deformation of the track, preventing internal cracks from appearing between the fixing plate inside the track and the track concrete, ensuring the overall stability of the track and extending its service life.

[0062] 2) The lower part of the track support system of the present invention is fixedly connected to the base concrete 4.

[0063] Specifically:

[0064] Since the connection methods between the track shear wall and track support columns and the base concrete 4 are the same; that is, the connection relationship between the first concrete column 2, the first central support column 3 and the base concrete 4 is the same as the connection relationship between the second concrete column 15, the second central support column 14 and the base concrete 4, the following description, using the connection method between the first concrete column 2, the first central support column 3 and the base concrete 4 as an example, illustrates the connection method between the track shear wall, the track support columns and the base concrete 4.

[0065] In one specific embodiment of the present invention, a lower fixing plate 7 is fixedly installed at the lower end of the first central support column 3, and the lower fixing plate 7 is fixedly connected to the base concrete 4.

[0066] Specifically, the first concrete column 2 and the base concrete 4 are integrally formed by concrete pouring.

[0067] Specifically, the lower end of the first central support column 3 is fixedly installed with the lower fixing plate 7 by welding or integral molding.

[0068] Specifically, the lower fixing plate 7 is installed inside the base concrete 4, such as... Figure 2 , Figure 3 As shown. Furthermore, during the pouring of the base concrete 4, the lower fixing plate 7 is poured into the interior of the base concrete 4 and is fixedly connected to the base concrete 4.

[0069] Furthermore, in order to improve the overall wind load and seismic resistance of the track, it is necessary to further improve the tightness and reliability of the connection between the fixing plate and the track concrete 1, and between the lower fixing plate 7 and the base concrete 4.

[0070] In one specific embodiment of the present invention, multiple tie rods are vertically arranged on the lower fixing plate 7. The tie rods can have various structural forms, such as... Figure 4 , Figure 9 , Figure 10 As shown.

[0071] 1) Specifically, such as Figure 2-4 As shown, in one specific embodiment of the present invention, the tie rod is a cylindrical support rod 8; multiple support rods 8 are arranged perpendicular to the lower fixing plate 7 and are welded and fixed to the lower fixing plate 7, as shown. Figure 2 , Figure 3 As shown. The bottom of the first central support column 3 is equipped with a lower fixing plate 7 and multiple support rods 8, which can simulate the shape of tree roots, making the first concrete column 2 and the base concrete 4 more tightly connected, less prone to tilting, and improving wind and earthquake resistance.

[0072] 2) Specifically, in another embodiment of the present invention, the tie rod is a corrugated support rod 8-1. Unlike a corrugated plate, the corrugated support rod 8-1 is a corrugated rod-like structure, such as... Figure 9 As shown.

[0073] 3) Specifically, such as Figure 10 As shown, the tie rod is a support rod 8 with spikes 8-2.

[0074] Multiple spikes 8-2 are provided on the support rod 8; the spikes 8-2 are obliquely arranged and fixedly connected to the support rod 8. The spikes 8-2 are fixedly connected to the support rod 8 by welding, and the spikes 8-2 and the support rod 8 are arranged at an acute angle, such as... Figure 10 As shown.

[0075] When the track support column of the present invention is subjected to vibration or wind load impact on the upper track, the support rod 8 or corrugated support rod 8-1 of the track support column can ensure the overall stability of the track, and at the same time disperse the impact force and reduce the internal stress of the base concrete 4.

[0076] Furthermore, rubber pads 6 are used for shock absorption and cushioning between the track support columns and the track concrete 1. However, the performance of rubber material is unstable, and its elastic properties change with temperature variations. Therefore, in order to realize the application of ski tracks in high-latitude, low-temperature regions, it is necessary to ensure the elastic properties of rubber pads 6 in low-temperature environments.

[0077] In one specific embodiment of the present invention, a protective cover 9 is provided over the rubber pad 6; a temperature control lamp 10 is installed on the protective cover 9, such as... Figure 4 As shown.

[0078] Specifically, the protective cover 9 has a cylindrical structure, and a temperature control lamp 10 is installed on the protective cover 9, such as... Figure 4 As shown.

[0079] Furthermore, the temperature control lamp 10 is nested on the side panel of the protective cover 9, as shown below. Figure 5 As shown.

[0080] Furthermore, one side of the temperature control lamp 10 protrudes from the inner wall surface of the protective cover 9, and the other side protrudes from the outer wall surface of the protective cover 9, such as... Figure 6 As shown. The portion of the temperature control lamp 10 located inside the protective cover 9 can illuminate the rubber pad 6, providing it with heat and preventing excessively low temperatures from affecting its performance; the portion of the temperature control lamp 10 located outside the protective cover 9 can provide illumination at night.

[0081] When the temperature is too low, the temperature control lamp 10 can be used to keep the rubber pad 6 warm. The outside of the temperature control lamp 10 is exposed to the outdoors and can be used for lighting. The protective cover 9 has the effects of blocking wind, rain and snow and preventing direct sunlight, which can effectively extend the service life of the rubber pad and save maintenance costs.

[0082] Considering that ski slopes are mostly built in mountainous areas of cold and temperate zones, even with the above-mentioned protective measures, the rubber mats 6 still face the risk of aging after long-term use.

[0083] In order to enable the replacement of the rubber pad 6, the rubber pad 6 of the present invention is a spliced ​​structure composed of multiple fan-shaped parts.

[0084] Specifically, the rubber pad 6 is composed of multiple sector-shaped sections. Preferably, there are four sector-shaped sections, such as... Figure 8 As shown.

[0085] In one specific embodiment of the present invention, such as Figure 8 As shown, when the sector-shaped parts are assembled into the rubber pad 6, the planar parts of adjacent sector-shaped parts are attached to each other, and the first arc surface and the second arc surface of adjacent sector-shaped parts are respectively assembled into two coaxial cylindrical surfaces.

[0086] Specifically, the first arc surface of the fan-shaped portion is in contact with the first central support column 3; the first cylindrical surface formed by the splicing of the first arc surfaces of multiple fan-shaped portions is in contact with the outer surface of the first central support column 3, such as... Figure 8 As shown.

[0087] Specifically, the second arc surface of the fan-shaped portion is aligned with the outer surface of the first concrete column 2. The second cylindrical surface formed by the splicing of the second arc surfaces of multiple fan-shaped portions is the outer surface of the rubber pad 6.

[0088] Furthermore, in order to fix the rubber pad 6 of the spliced ​​structure, the present invention also provides a limiting structure.

[0089] Specifically, the track support column is provided with a protrusion 21, and a sleeve 23 is nested in the protrusion 21. A bolt 22 is installed in the sleeve 23. The bolt 22 extends out of the upper surface of the protrusion 21 to limit the rubber pad 6. Further, the height of the bolt 22 extending out of the protrusion 21 is less than the thickness of the rubber pad 6. Figure 7 , Figure 8 As shown.

[0090] During implementation: When it is necessary to replace the rubber pad 6, adjust or remove the bolt 22 to remove the old rubber pad 6; insert the multiple fan-shaped parts of the new rubber pad 6 into the track concrete 1 and the first concrete column 2 in sequence; screw the bolt 22 into the protrusion 21, with the upper end of the bolt 22 protruding from the upper surface of the protrusion 21 and contacting the outer surface (i.e., the second cylindrical surface) of the rubber pad 6 to limit the rubber pad 6, keep the parts of the rubber pad 6 in close contact, prevent the rubber pad 6 from shifting and keep the overall structure of the rubber pad 6 from becoming loose.

[0091] Compared with the prior art, the technical solution provided in this embodiment has at least one of the following effects:

[0092] 1. The track support system of the present invention uses track shear walls as rigid supports for the main body of the track, namely the track concrete, while track support columns with rubber pads installed on top provide flexible support for the track concrete. The track support system of the present invention achieves support for the track concrete through the cooperation of track shear walls and track support columns. This combination of rigid and flexible support improves the impact resistance and overall stability of the track while ensuring reliable support for the track concrete.

[0093] 2. The track support system of the present invention adopts a portal structure composed of double concrete columns and beams as the track shear wall. The track shear wall is cast as a whole with the track concrete, which makes the support system more stable in connection with the track body. The portal structure track shear wall serves as a rigid support for the track concrete, ensuring the overall stability of the track.

[0094] 3. The track support system of the present invention sets multiple sets of track support columns as flexible supports between two adjacent sets of track shear walls. Compared with the track shear walls, rubber pads are set between the concrete columns of the track support columns and the track concrete for vibration isolation and buffering. When the track is put into use, the flexible track support columns can allow the track body to undergo slight deformation, and the rubber pads can buffer the rigid impact between the track concrete and the concrete columns, ensuring the track's ductility and seismic performance.

[0095] 4. The temperature-controlled lamp 10 of the present invention is nested and installed on the protective cover 9. When the temperature is too low, the illumination of the temperature-controlled lamp 10 can be used to keep the rubber pad 6 warm. The outer side of the temperature-controlled lamp 10 is exposed to the outdoors and can be used for lighting. Furthermore, the temperature-controlled lamp 10 is powered by a solar panel installed on the first concrete column 2, thus saving energy.

[0096] 5. The rubber pad 6 of this invention is a detachable, multi-piece assembly structure; after long-term use or when the performance of the rubber pad deteriorates due to weathering, temperature, etc., it is convenient to replace the rubber pad, thereby maintaining the overall stability of the track. Furthermore, a protrusion 21 is provided above the first concrete column 2, with a sleeve 23 nested inside as a bolt sleeve, and bolts 22 installed inside. The bolt tightening height can limit the rubber pad, maintaining a tight fit between the various parts of the rubber pad and preventing displacement; when replacement is needed, the bolts can be lowered or removed to facilitate inserting the rubber pad 6 between the base concrete 4 and the first concrete column 2.

[0097] 6. The track support column of the present invention is provided with an upper fixing plate 5 on the first central support column 3. The upper fixing plate 5 is located inside the track concrete 1 and is a corrugated plate. When the track is in use, the track will undergo slight bending deformation under the impact of movement. The corrugated upper fixing plate allows the metal steel fixing plate to follow the deformation of the track, avoiding internal cracks between the fixing plate inside the track and the track concrete, ensuring the overall stability of the track and extending its service life.

[0098] 7. In the track support column of the present invention, the first central support column 3 is fixed to the base concrete 4 by the lower fixing plate 7. Then, by installing multiple tie rods, i.e., support rods 8 or corrugated support rods 8-1 on the lower fixing plate 7, the multiple tie rods and the lower fixing plate 7 form a structural system similar to plant roots, making the connection between the track support column and the base concrete tighter. When the upper track is subjected to vibration impact or wind load impact, the tie rods can ensure the overall stability of the track, while also dispersing the impact force and reducing the internal stress of the base concrete.

[0099] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
