Description

Technical Field

[0001] This invention relates to the field of track technology, and in particular to a track support column. 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, to maintain the stable performance of elastic rubber pads, the ambient temperature needs to be kept neither too high nor too low. However, ski slopes are mostly built in cold and temperate regions, where cold winters and hot summers affect the rubber's properties. Furthermore, once plastic deformation occurs, it is irreversible, leading to high maintenance and repair costs and reducing the track's lifespan. Additionally, ski slopes are susceptible to repeated impacts during use, and since they are often built in mountainous areas, they are subject to significant wind loads. Over time, the support pillars are prone to tilting, altering the slope of the upper track surface, affecting normal use, and posing safety hazards.

[0006] Therefore, it is necessary to further improve the tightness between the concrete support columns of the track and the main track body and concrete base plate. Summary of the Invention

[0007] Based on the above analysis, the present invention aims to provide a track support column to solve the problem that the performance of the rubber pads of existing track columns is reduced due to temperature, resulting in poor track stability.

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

[0009] A track support column includes: a concrete column, a central support column, and an elastic pad; the concrete column is disposed outside the central support column; the concrete column is supported between track concrete and base concrete; the elastic pad is disposed between the concrete column and the track concrete; a protective cover and a temperature control light are disposed outside the elastic pad.

[0010] Furthermore, the elastic pad is a multi-piece assembled structure; the elastic pad includes multiple fan-shaped portions; the first arc surface of the fan-shaped portion contacts the central support column; the second arc surface of the fan-shaped portion has the same diameter as the outer surface of the concrete column.

[0011] Furthermore, the upper part of the concrete column is provided with a protrusion, and a sleeve is embedded in the protrusion; a bolt is installed in the sleeve; the bolt can limit the elastic pad and can be unscrewed from the upper surface of the protrusion. Specifically, when the bolt is unscrewed from the upper surface of the protrusion, it can limit the elastic pad.

[0012] Furthermore, the upper end of the central support column extends into the track concrete, and a fixing plate is fixedly installed on the upper end of the central support column; specifically, the upper fixing plate is a corrugated plate.

[0013] Furthermore, the lower end of the central support column extends into the base concrete, and a lower fixing plate is fixedly installed at the lower end of the central support column; the lower fixing plate is fixedly connected to the base concrete.

[0014] Furthermore, multiple tie rods are installed on the lower fixing plate; the tie rods are arranged perpendicular to the lower fixing plate.

[0015] Furthermore, the tie rod is a cylindrical support rod.

[0016] Furthermore, the support rod is provided with multiple spikes.

[0017] Furthermore, the tie rod is a corrugated support rod.

[0018] Furthermore, a solar panel is installed on the concrete column; the solar panel is used to power the temperature-controlled lamp.

[0019] The technical solution of this invention can achieve at least one of the following effects:

[0020] 1. The present invention is equipped with a temperature control lamp and a protective cover. When the temperature is too low, the temperature control lamp can be used to keep the rubber pad warm, and at the same time, it can achieve the effect of nighttime lighting.

[0021] 2. The track support column of the present invention adopts a detachable, multi-piece assembled elastic pad; after the performance of the elastic pad deteriorates, it is convenient to replace the elastic pad, thereby maintaining the overall stability of the track.

[0022] 3. The track support column of the present invention has a corrugated plate as an upper fixing plate on the central support column, and the upper fixing plate is integrally cast with the track concrete. During use, the track will undergo slight bending deformation under the impact of movement. The corrugated upper fixing plate can follow the deformation of the track, avoid cracks in the track, ensure the overall stability of the track, and extend its service life.

[0023] 4. The track support column of this invention has a central support column that is fixed to the base concrete by a lower fixing plate. Multiple corrugated support rods are installed on the lower fixing plate to form a plant root-like structural system, which makes the connection between the track support column and the base concrete tighter and ensures the overall stability of the track when the upper track is subjected to vibration or wind load.

[0024] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations.

[0036] 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.

[0037] Example 1

[0038] A specific embodiment of the present invention discloses a track support column, comprising: a concrete column 2, a central support column 3, and an elastic pad 6; the concrete column 2 is disposed outside the central support column 3; the concrete column 2 is supported between track concrete 1 and base concrete 4; the elastic pad 6 is disposed between the concrete column 2 and the track concrete 1; the elastic pad 6 is a multi-piece assembled structure; a protective cover 9 and a temperature control lamp 10 are disposed outside the elastic pad 6.

[0039] The traditional elastic pad 6 is a ring-shaped rubber band, which is fitted over the outside of the metal central support column 3 and placed between the concrete column 2 and the track concrete 1. During track use, the track itself undergoes slight elastic deformation (i.e., minor vibration) due to the impact of athletes' movements. The rubber pad can cushion this vibration. However, when exposed to the natural environment, including wind, sun, rain, and sustained high or low temperatures, the rubber pad will age or deform, leading to a decline in performance. Once its performance deteriorates, the rubber pad cannot effectively absorb shocks and will create gaps between the concrete column 2 and the track concrete 1, affecting the overall stability of the track.

[0040] In one specific embodiment of the present invention, the elastic pad 6 is made of rubber.

[0041] In order to extend the service life of the elastic pad and reduce the manpower and material costs of track maintenance, the track support column of the present invention is provided with a protective cover 9 above the concrete column 2, and a temperature control lamp 10 is installed on the protective cover 9 to maintain the shock absorption performance of the elastic pad 6 in a continuous low temperature environment.

[0042] Specifically, such as Figure 1 As shown, the protective cover 9 has a cylindrical structure, and a temperature control lamp 10 is installed on the protective cover 9, such as... Figure 1 As shown.

[0043] Furthermore, the temperature control lamp 10 is nested on the side panel of the protective cover 9.

[0044] 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 2 As shown.

[0045] The portion of the temperature-controlled lamp 10 located inside the protective cover 9 can irradiate the elastic pad 6, providing it with heat and preventing the temperature from being too low and affecting its performance; the portion of the temperature-controlled lamp 10 located outside the protective cover 9 can provide illumination at night.

[0046] Furthermore, the temperature-controlled lamp 10 is an incandescent lamp.

[0047] While illuminating, the temperature-controlled lamp 10 of the present invention radiates a certain amount of heat. In the cold winter conditions, it can keep the elastic pad 6 warm, prevent the elastic pad 6 from becoming too hard at low temperatures, maintain the elasticity of the elastic pad 6, and enable it to act as an elastic pad 6 to elastically buffer the vibration or deformation of the track concrete 1 above, thus ensuring the track's seismic resistance.

[0048] Furthermore, the temperature control lamp 10 has an arc-shaped structure, and the radius of the temperature control lamp 10 is equal to the radius of the protective cover 9, such as... Figure 3 As shown. Specifically, the upper part of the track support column of the present invention consists of, from the inside out, a central support column 3, an elastic pad 6, a protective cover 9, and a temperature control lamp 10. The protective cover 9 has the function of preventing direct sunlight in summer and resisting wind and snow in winter.

[0049] Furthermore, a solar panel 11 is installed on the concrete column 2; the solar panel 11 is used to supply power to the temperature control lamp 10.

[0050] Furthermore, a temperature sensor and a light sensor are installed on the outside of the protective cover 9 to detect the temperature and light intensity of the external environment.

[0051] Furthermore, a temperature control switch and a light sensor switch are installed inside the protective cover 9. When the light sensor detects that the external environment is dark, the light sensor switch activates the temperature control lamp 10 for illumination. When the temperature sensor detects that the external ambient temperature is below the low temperature threshold, the temperature control lamp 10 is activated for heat preservation.

[0052] Specifically, in winter when temperatures are low, the temperature control lamp 10 is activated to keep the room warm while also providing nighttime lighting.

[0053] Considering that the shock absorption performance of the elastic pad 6 decreases after aging, the present invention adopts a modular structure to facilitate the disassembly and replacement of the elastic pad 6.

[0054] Specifically, the elastic pad 6 of the present invention is assembled from multiple pieces. After a period of use, the aged elastic pad 6 can be removed, and multiple new rubber blocks can be filled between the concrete column 2 and the track concrete 1 to assemble a new elastic pad 6. The assembly and disassembly are convenient, which makes it easy to maintain the performance stability of the elastic pad 6 and thus maintain the overall stability of the track.

[0055] In one specific embodiment of the present invention, such as Figure 5 As shown, the elastic pad 6 includes multiple fan-shaped portions 61 with the same shape; the first arc surface 62 of the fan-shaped portion 61 contacts the central support column 3; the second arc surface 63 of the fan-shaped portion 61 has the same diameter as the outer surface of the concrete column 2.

[0056] Specifically, the first cylindrical surface formed by the first arc surfaces 32 of multiple sector-shaped portions 31 is in contact with the outer surface of the central support column 3 and has the same diameter. Furthermore, the second cylindrical surface formed by the second arc surfaces 33 of multiple sector-shaped portions 31 has the same diameter as the outer surface of the concrete column 2.

[0057] Furthermore, the elastic pad 6 in the multi-piece assembled structure needs to maintain its own structural integrity and ensure the stability of the overall shape. To address this issue, this invention proposes two feasible solutions:

[0058] The first method: adding external constraints to limit the shape.

[0059] Specifically, there are at least two constraint methods: using bolts for limiting or using metal wire binding.

[0060] 1) such as Figure 5 As shown, in one specific embodiment of the present invention, a protrusion 21 is provided on the upper part of the concrete column 2, and an installation sleeve 23 is embedded in the protrusion 21; a bolt 22 is installed in the sleeve 23; when the bolt 22 is unscrewed from the upper surface of the protrusion 21, it can limit the elastic pad 6, such as... Figure 4 As shown.

[0061] Specifically, the sleeve 23 has an internal thread; the bolt 22 is screwed into the sleeve 23 via the thread. Furthermore, the sleeve 23 is made of metal and is embedded in the concrete column 2 during pouring; the bolt 22 is threaded to the sleeve 23, facilitating the installation and removal of the bolt 22.

[0062] During implementation: A protrusion 21 is provided above the concrete column 2. A sleeve 23 is nested inside the protrusion 21 as a bolt sleeve. A bolt 22 is installed in the sleeve 23. The bolt height can limit the elastic pad 6, keep the various parts of the elastic pad 6 tightly fitted, and prevent the elastic pad 6 from shifting. When the elastic pad 6 needs to be replaced, the bolt 22 is lowered or removed, the old elastic pad 6 is removed, and the multiple parts of the new elastic pad 6 are sequentially inserted between the track concrete 1 and the concrete column 2. The bolt 22 is screwed into the protrusion 21. The upper end of the bolt 22 protrudes from the upper surface of the protrusion 21 and contacts the outer surface of the elastic pad 6, preventing the elastic pad 6 from shifting and keeping the overall structure of the elastic pad 6 intact.

[0063] Furthermore, the height of bolt 22 extending from the upper surface of the concrete column 2 is less than the thickness of the elastic pad 6. This ensures that while the fixing bolt limits the elastic pad, it does not affect the use of the elastic pad and can avoid it when the track concrete undergoes elastic deformation; that is, it ensures that the track concrete and the fixing bolt will not interfere after the elastic pad is compressed.

[0064] 2) In another embodiment of the present invention, multiple turns of metal wire are bound to the second arc surface 63 of the plurality of sector portions 61 of the elastic pad 6. The metal wire limits the plurality of sector portions 61 and maintains the overall stability of the elastic pad 6. When replacing, the external metal wire is removed first, and then the elastic pad 6 is replaced. After the elastic pad 6 is installed, a new metal wire is bound on it.

[0065] Furthermore, in traditional racetracks, a metal plate is installed between the track concrete 1 and the central support column 3 for fixed connection. When the track body vibrates or deforms, the vibration impact will act on the metal plate. Since the metal plate and the central support column 3 are made of metal, while the track body is made of concrete, due to the difference in their strength and stiffness, after repeated impacts, the track concrete 1 and the central support column 3 are prone to separate at the track support column position, which in turn leads to cracks in the track body and affects the stability of the track.

[0066] The second method: using a locking structure for positioning.

[0067] Specifically, a protruding engaging ridge is provided at the bottom of the fan-shaped part, and a concave engaging groove is provided on the upper surface of the concrete column 2. Through the cooperation of the engaging groove and the engaging ridge, the fan-shaped part has a definite position.

[0068] Specifically, multiple radially distributed locking grooves are provided on the upper surface of the concrete column 2, and the number of locking grooves is the same as the number of fan-shaped parts. When the locking protrusions of the fan-shaped parts are engaged in the locking grooves, the multiple fan-shaped parts are combined into a complete elastic pad.

[0069] In one specific embodiment of the present invention, the upper end of the central support column 3 extends into the track concrete 1, and the upper end of the central support column 3 is fixedly installed with an upper fixing plate 5; the upper fixing plate 5 is a corrugated plate.

[0070] In this invention, a corrugated metal plate is provided at the upper end of the central support column 3 as an upper fixing plate 5, which makes the track support column and the track concrete 1 more tightly bonded. The upper fixing plate 5 is a curved structure, which has better buckling performance and is more likely to follow the deformation of the track, thus avoiding internal cracks.

[0071] Furthermore, since many racetracks 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 use, and posing safety hazards. Therefore, it is necessary to further improve the stability between the concrete support columns and the main track structure and concrete base slab.

[0072] In one specific embodiment of the present invention, the lower end of the central support column 3 extends into the base concrete 4, and the lower end of the central support column 3 is fixedly installed with a lower fixing plate 7; the lower fixing plate 7 is fixedly connected to the base concrete 4.

[0073] In one specific embodiment of the present invention, multiple tie rods are installed on the lower fixing plate 7; the tie rods are arranged perpendicular to the lower fixing plate 7.

[0074] In one specific embodiment of the present invention, such as Figure 1 As shown, the tie rod is a cylindrical support rod 8. Specifically, the support rods 8 are evenly distributed in an array on the lower fixed plate 7.

[0075] Alternatively, in another specific embodiment of the present invention, the tie rod is a corrugated support rod 8-1, such as... Figure 6 As shown.

[0076] In this invention, a lower fixing plate 7 and a support rod 8 are provided at the bottom of the central support column 3, which can simulate the shape of tree roots, making the concrete column 2 and the base concrete 4 more tightly connected, less prone to tilting, and improving wind and earthquake resistance.

[0077] Furthermore, the support rod 8 is provided with a plurality of spikes 8-2; the spikes 8-2 are obliquely arranged and fixedly connected to the support rod 8, such as... Figure 7 As shown.

[0078] Specifically, the spike 8-2 is fixedly connected to the support rod 8 by welding, and the spike 8-2 and the support rod 8 are set at an acute angle.

[0079] 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.

[0080] Compared with the prior art, the technical solution provided by the present invention has at least one of the following beneficial effects:

[0081] 1. The temperature-controlled lamp 10 of this invention is nested and installed on the protective cover 9. When the temperature is too low, the illumination from the temperature-controlled lamp 10 can be used to insulate the elastic pad 6. The outer side of the temperature-controlled lamp 10 is exposed to the outdoors and can be used for lighting. The track support column of this invention has the effects of insulating the elastic pad 6 inside the protective cover 9 and providing nighttime lighting. Furthermore, the temperature-controlled lamp 10 is powered by a solar panel installed on the concrete column 2, saving energy.

[0082] 2. The elastic pad 6 of this invention is a detachable, multi-piece assembly structure; after long-term use or when the performance of the elastic pad deteriorates due to weathering, temperature, etc., it is convenient to replace the elastic pad, thereby maintaining the overall stability of the track. Furthermore, a protrusion 21 is provided above the concrete column 2, with a sleeve 23 nested inside as a bolt sleeve, and a bolt 22 installed inside. The bolt 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 bolt can be lowered or removed to easily insert the elastic pad between the track concrete and the concrete column.

[0083] 3. The track support column of the present invention has an upper fixing plate 5 on the central support column 3. The upper fixing plate 5 is set 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.

[0084] 4. In this invention, the track support column, the 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 plant root-like structural system, making the connection between the track support column and the base concrete tighter. When the upper track is subjected to vibration 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.

[0085] 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.
