Description

Technical Field

[0001] This utility model relates to the field of sports field paving technology, specifically to a plastic running track with good fixing effect. Background Technology

[0002] As a crucial component of sports venues, the stability of synthetic running tracks directly impacts safety and durability. Traditional synthetic running tracks suffer from significant construction defects: the track body is simply bonded to the ground or fixed by gravity, making it prone to displacement under long-term foot traffic, temperature variations, or rain erosion. Particularly problematic are the joints, which lack effective mechanical fixing structures, often resulting in seam cracking or overall slippage. This not only shortens the track's lifespan but also poses a tripping hazard to athletes. Existing fixing methods often employ either a monolithic base layer or distributed ground stakes. The former cannot adapt to localized deformation caused by foundation settlement, while the latter suffers from weakened fixing force due to insufficient support area at the fixing points. Furthermore, conventional positioning structures lack multi-directional restraint design, making it difficult to resist lateral stresses generated by the thermal expansion and contraction of the synthetic material, leading to wavy deformation on the track surface.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a plastic running track with good fixation effect, which has the advantages of enhancing the overall stability of the track through a multi-directional limiting structure and effectively resisting thermal expansion and contraction stress.

[0005] This application provides a plastic running track with good fixing effect. The technical solution is as follows: it includes a running track body, a base plate at the bottom of the running track body, positioning components at the four corners of the bottom of the base plate, the positioning components including fixing posts, the top of the fixing posts contacting the base plate, diagonal bars on both sides of the fixing posts, an opening in the inner cavity of the fixing posts, a threaded hole at the bottom of the inner cavity of the opening, a horizontal plate at the bottom of the inner cavity of the opening, mounting bolts fitted in the inner cavity of the horizontal plate, and the bottom of the mounting bolts threadedly connected to the threaded hole, and limiting cone rods on both sides of the bottom of the horizontal plate.

[0006] Furthermore, this application also proposes that a fixing plate is fixedly connected to the top of the fixing column, and the inner cavity of the fixing plate is fixedly connected to the base plate by fixing bolts.

[0007] Furthermore, this application also proposes that the two ends of the bottom of the horizontal plate are fixedly connected to the limiting cone rods by connecting blocks, and the two limiting cone rods are arranged symmetrically about the horizontal plate.

[0008] Furthermore, this application also proposes that at least three diagonal braces are equally spaced on both sides of the fixed column, and the two sets of diagonal braces are arranged symmetrically.

[0009] Furthermore, this application also proposes that the bottom left side of the base plate is provided with slots at both ends, the inner cavity of the slots is provided with barb grooves at both ends, and the right side of the base plate is provided with blocks at both ends, the blocks being provided with barb limiting blocks that are adapted to the barb grooves.

[0010] Furthermore, this application also proposes that the size of the card block is consistent with the inner cavity of the card slot, and that the card block is in close contact with the inner cavity of the card slot.

[0011] As can be seen from the above, the plastic running track and its positioning components provided in this application have a good fixing effect. The diagonal rods and limiting cone rods in the four corner positioning components form a multi-directional support structure. The three-dimensional fixing is achieved with the help of the threaded installation bolts. It effectively disperses stress and suppresses track displacement. It has the advantages of enhancing the overall stability of the track through the multi-directional limiting structure and effectively resisting thermal expansion and contraction stress.

Detailed Implementation

[0014] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0015] Please see Figure 1-5 In existing technologies, the fixing methods for plastic running tracks mostly rely on single bolts or adhesive bonding. Traditional fixing structures cannot adapt to different ground conditions and are prone to displacement in damp or soft foundation environments. During the construction of sports fields, uneven foundations or settlement of backfill soil are often encountered. Existing fixing devices cannot form effective multi-point anchorage, resulting in gaps at the joints of the running track and affecting safety during use.

[0016] To address these issues, researchers observed that runway displacement primarily occurred at the four corners, revealing that traditional single-point anchoring methods were ineffective in dispersing the impact forces. Analysis of the runway's stress patterns identified lateral shear force as the primary cause of anchoring failure. Based on this, a proposal was made to install independent anchoring units at the four corners of the runway, forming a three-dimensional anchoring network through a multi-directional limiting structure.

[0017] Therefore, this application proposes a combined structure including a runway body 1 and a base plate 2, with positioning components 3 installed at the four corners of the bottom of the base plate 2. Each positioning component 3 includes a vertical fixing column 301, with diagonal support rods on both sides of the fixing column 301, and a through channel within the column. A threaded interface is provided at the bottom of the channel, and an adjustable horizontal plate 306 is installed inside. Two symmetrically distributed conical ground stakes are connected below the horizontal plate 306. The height of the horizontal plate 306 is adjusted via bolts and the threaded interface.

[0018] Among them, positioning component 3 refers to the anchoring unit set at the four corners of the runway. Specifically, it can be realized by using a composite structure of metal castings and polymer materials to disperse the vertical pressure and lateral shear force borne by the runway.

[0019] The fixed column 301 refers to a vertically installed load-bearing component, which can be implemented using a hollow cylindrical structure, serving as the core force transmission component of the anchoring system.

[0020] The diagonal brace 304 refers to the structural component that forms an angle with the fixed column 301. Specifically, it can be implemented by welding a steel pipe with a gradually changing diameter to enhance the anti-tilting ability of the fixed column 301.

[0021] The through-hole 305 refers to the vertical channel that passes through the fixed column 301. Specifically, it can be realized by using a circular hole structure formed by machining, providing operating space for the installation and adjustment mechanism.

[0022] The threaded hole 307 refers to the connection interface located at the bottom of the through port 305. Specifically, it can be achieved by using a standard thread structure formed by tapping process to realize the detachable connection of the bolt assembly.

[0023] The horizontal plate 306 refers to a horizontally set mounting base, which can be made of a rectangular steel plate with a central through hole, serving as an installation platform for the tapered ground nail.

[0024] Mounting bolt 308 refers to the fastener that connects the horizontal plate 306 and the threaded hole 307. Specifically, it can be implemented using galvanized hexagonal bolts to achieve adjustable anchoring depth.

[0025] The limiting cone rod 3010 refers to a fixed component that is inserted into the ground. Specifically, it can be implemented using a tapered steel rod with a spiral pattern on the surface, which increases the contact area with the soil and improves the pull-out resistance.

[0026] Specifically, during installation, the fixing column 301 is first erected vertically in the preset position, and a stable triangular support is formed by welding the diagonal brace 304 at an angle. The horizontal plate 306 is then fitted into the through-hole 305, and the mounting bolts 308 are tightened, so that the bolt ends screw into the threaded holes 307 to form a rigid connection. Adjusting the bolt insertion depth controls the height of the horizontal plate 306, causing the limiting cone rod 3010 to insert into the ground at a preset angle. Two sets of symmetrically distributed limiting cone rods 3010 form a V-shaped anchoring structure, generating a counterforce in the soil. The diagonal brace 304 forms a 45-60 degree angle with the fixing column 301, converting the horizontal load into axial pressure. When the foundation experiences slight displacement, the helical texture on the surface of the cone rod generates a self-locking effect through soil friction.

[0027] Compared to existing technologies, traditional runway fixing relies on a single vertical anchor, while this solution uses a four-corner three-dimensional anchoring system to form a spatial force network. Existing technologies do not allow for adjustable anchoring depths; this solution uses bolt connections to dynamically adjust the insertion angle of the cone rod. Conventional fixing devices lack lateral support; this solution combines the diagonal 304 brace with the cone rod to form a two-way shear-resistant structure.

[0028] Through the above technical solutions, this application achieves independent reinforcement of the four corner areas of the runway, effectively dispersing the concentrated stress generated by sports impacts. The conical ground stakes and diagonal support rods work together to adapt to different geological conditions such as sand and clay. The adjustable bolt structure allows for flexible adjustment of the installation depth according to the foundation hardness, preventing damage to the base layer due to over-insertion. The multi-directional limiting mechanism significantly improves the runway's resistance to displacement in humid environments, ensuring the structural integrity of the joints at the sports surface layer.

[0029] This application further proposes that the top of the fixed column 301 is fixedly connected to a fixed plate 302, and the inner cavity of the fixed plate 302 is fixedly connected to the base plate 2 by a fixing bolt 303.

[0030] Among them, the fixing plate 302 refers to the plate-like structure that covers the top of the fixing column 301 and contacts the base plate 2. Specifically, it can be made of metal plate or rigid plastic plate. Its function is to increase the connection strength between the fixing column 301 and the base plate 2 by increasing the contact area.

[0031] Among them, the fixing bolt 303 refers to the threaded fastener that passes through the fixing plate 302 and the base plate 2. Specifically, it can be achieved by using stainless steel bolts and nuts. The thread engagement forms a detachable connection, which facilitates installation and maintenance while ensuring the rigid fixation of the fixing plate 302 and the base plate 2.

[0032] Specifically, during installation, the fixing plate 302 is pre-fixed to the top of the fixing column 301 by welding or integral molding. Then, the fixing plate 302 is attached to the preset position of the base plate 2, and the fixing bolts 303 are used to lock the fixing plate 302 by passing through the pre-drilled holes in the base plate 2 and the threaded structure inside the fixing plate 302. Thus, a double fixing structure is formed at the connection between the fixing column 301 and the base plate 2. On the one hand, the fixing plate 302 disperses the local pressure of the fixing column 301 on the base plate 2, and on the other hand, the axial locking force of the bolts eliminates the connection gap, preventing the fixing column 301 from separating from the base plate 2 due to external vibration.

[0033] Compared with existing technologies, the connection between the traditional plastic track fixing column 301 and the base plate 2 is mostly achieved by direct welding or adhesive bonding, which results in difficulties in disassembly and high maintenance costs. This solution, through the combination structure of fixing plate 302 and bolts, retains the stability of welded connections while enabling modular installation through a detachable design. At the same time, the planar contact of fixing plate 302 effectively avoids local stress concentration that may occur when bolts are directly tightened.

[0034] Through the above technical solution, this application can significantly improve the connection reliability between the fixed column 301 and the base plate 2, prevent the fixed column 301 from loosening due to long-term trampling or ground subsidence of the plastic track, and simplify the installation and disassembly process, making it easier to replace the fixed components that are partially damaged, thereby reducing maintenance costs.

[0035] This application further proposes that the two ends of the bottom of the horizontal plate 306 are fixedly connected to the limiting cone rod 3010 by the connecting block 309, and the two limiting cone rods 3010 are arranged in a centrally symmetrical manner about the horizontal plate 306.

[0036] The connecting block 309 is a rigid component used to connect the horizontal plate 306 and the limiting cone rod 3010. It can be implemented by welding or bolting a metal block. Its function is to enhance the structural strength between the horizontal plate 306 and the limiting cone rod 3010 and prevent the connection from breaking due to external impact.

[0037] The central symmetry setting refers to the two limiting cone rods 3010 being symmetrically distributed with the geometric center of the horizontal plate 306 as the reference. Specifically, this can be achieved by using equally spaced mounting holes. Its function is to balance the force distribution when the limiting cone rods 3010 are inserted into the ground and prevent the horizontal plate 306 from tilting due to uneven force on one side.

[0038] Specifically, during installation, the horizontal plate 306 is rigidly connected to the limiting cone rod 3010 via the connecting block 309. The connecting block 309 evenly transfers the vertical load borne by the horizontal plate 306 to the limiting cone rod 3010. When the limiting cone rod 3010 is inserted into the ground, the centrally symmetrical layout causes the ground reaction forces on both sides of the cone rod to cancel each other out, thereby maintaining the horizontal plate 306 in a horizontal state. This structure, through the synergistic effect of mechanical connection and symmetrical layout, ensures that the mounting bolts 308 will not loosen due to force displacement during the fixing process.

[0039] Compared to existing technologies, in traditional plastic running track fixing structures, the limiting rods are typically welded directly to the bottom of the horizontal plate 306. This connection is prone to cracking due to stress concentration, and the asymmetrical layout leads to stress imbalance in the fixing device. This solution disperses stress concentration points through the connecting block 309 and achieves mechanical balance through a symmetrical layout, fundamentally solving the problem of easy deformation of the fixing device.

[0040] Through the above technical solution, this application effectively improves the connection reliability between the horizontal plate 306 and the limiting cone rod 3010, prevents the plastic track from shifting due to breakage at the connection or uneven force, and ensures that the main body of the track 1 remains stable and fixed during long-term use.

[0041] This application further proposes that at least three inclined rods 304 are equally spaced on both sides of the fixed column 301, and the two sets of inclined rods 304 are arranged symmetrically.

[0042] Among them, the diagonal bar 304 refers to the bar that forms an inclined support structure with the side wall of the fixed column 301. Specifically, it can be achieved by welding or bolting metal materials. Its function is to distribute the lateral load borne by the fixed column 301 at multiple angles and enhance the anti-overturning ability.

[0043] The equidistant setting refers to the uniform distribution of the spacing between adjacent diagonal bars 304. Specifically, this can be achieved by using standardized molds to process positioning holes. Its function is to form a regular support layout and avoid local stress concentration that could lead to structural deformation.

[0044] The symmetrical arrangement refers to the two sets of diagonal braces 304 forming a mirror distribution relative to the axis of the fixed column 301. This can be achieved through a dual-station synchronous assembly process. Its function is to balance the supporting forces on both sides and maintain the stability of the vertical state of the fixed column 301.

[0045] Specifically, when at least three diagonal braces 304 are installed on each side of the fixed column 301, the inclination angle of the diagonal braces 304 can be adjusted according to the ground foundation conditions. For example, a larger inclination angle can be used in soft ground to expand the support range. The lower end of each diagonal brace 304 is connected to the foundation through anchors, and the upper end is fixed to the side wall of the fixed column 301 through connectors. When the runway main body 1 is subjected to lateral impact, the multiple diagonal braces 304 work together to form a mesh support system, transmitting the impact force to the deep foundation in different directions, effectively suppressing the horizontal displacement of the fixed column 301.

[0046] Compared to existing technologies, traditional plastic running track fixing structures typically only have a single diagonal brace on each side of the uprights, resulting in too few support points and a single stress path. This solution, by increasing the number of 304 diagonal braces and optimizing their layout, creates a multi-level load transfer path in the support system, significantly improving its adaptability to complex loads. Especially in the track edge areas that frequently experience impacts, it can prevent cascading damage caused by localized support failure.

[0047] Through the above technical solution, this application can significantly enhance the connection strength between the fixed column 301 and the foundation, reduce the risk of displacement of the plastic track due to long-term use or external impact, and ensure the long-term stability of the track body 1 in high-frequency use scenarios of sports venues.

[0048] This application further proposes that the bottom left end of the base plate 2 is provided with slots 4, the inner end of the slot 4 is provided with barb grooves 5, the bottom right end of the base plate is provided with blocks 6, and the two ends of the blocks 6 are provided with barb limiting blocks 7 that are adapted to the barb grooves 5.

[0049] The groove 4 refers to the recessed structure on the left side of the runway base plate, which can be rectangular or trapezoidal in shape, used to accommodate the insertion of the right-side locking block 6. The barb groove 5 refers to the serrated grooves distributed on both sides of the inner wall of the groove 4, which can be triangular or trapezoidal in shape, increasing the frictional resistance of the contact surface to prevent accidental disengagement after engagement. The locking block 6 refers to the protruding structure on the right side of the base plate, which can be geometrically complementary to the groove 4, used to physically engage with the groove 4 of the adjacent runway. The barb limiting block 7 refers to the protruding structures distributed on both sides of the locking block 6, which can be made of elastic material and form an interference fit with the barb groove 5, enhancing the anti-displacement capability after splicing through mechanical interlocking.

[0050] Specifically, when the splicing ends of two adjacent runways approach each other, the right-side locking block 6 is guided into the left-side locking groove 4. During this process, the barbed limiting blocks 7 on both sides of the locking block 6 come into contact with the barbed grooves 5 on the inner wall of the locking groove 4. The barbed limiting blocks 7 are compressed and undergo elastic deformation until they are fully inserted into the barbed grooves 5 and then return to their original shape, forming a bidirectional limiting. At this time, the contact surface between the locking block 6 and the locking groove 4 generates a continuous clamping force through the interlocking effect of the barbed structure, effectively resisting the impact of lateral shear force on the splicing part.

[0051] Compared to existing technologies, traditional runway splicing often uses planar snap-fit ​​or bolt fixing. The former is prone to gaps due to vibration, while the latter suffers from low installation efficiency. This solution, through the cooperation of barbed groove 5 and barbed limiting block 7, maintains the advantage of rapid splicing while enhancing connection stability through the self-locking effect generated by elastic deformation, achieving anti-displacement function without the need for additional fasteners.

[0052] Through the above technical solution, this application effectively solves the misalignment problem caused by external forces after runway splicing. The barbed interlocking structure of the slot 4 and the block 6 forms a multi-directional constraint, which significantly improves the shear resistance of the splicing part and ensures that the runway unit maintains a stable relative position during long-term use.

[0053] This application further proposes that the size of the card block 6 is consistent with the inner cavity of the card slot 4, and the card block 6 is in close contact with the inner cavity of the card slot 4. Both ends of the inner cavity of the card slot 4 are provided with barb grooves 5, and both ends of the card block 6 are provided with barb limiting blocks 7 that are adapted to the barb grooves 5.

[0054] The slot 4 refers to the groove structure opened at both ends of the left side of the base plate, which can be implemented using a rectangular or trapezoidal cross-section groove, used to accommodate the insertion of the locking block 6. The barb groove 5 refers to the groove with a one-way limiting structure opened at both ends of the inner cavity of the slot 4, which can be implemented using a triangular or trapezoidal cross-section groove, and forms a mechanical lock through the cooperation of the barb limiting block 7 and the barb groove 5. The locking block 6 refers to the protrusion structure set at both ends of the right side of the base plate, which can be implemented using a solid block that matches the shape of the slot 4, and achieves splicing and positioning through close contact. The barb limiting block 7 refers to the limiting protrusion at both ends of the locking block 6 that is complementary in shape to the barb groove 5, which can be implemented using an elastic material or a rigid protrusion structure, and forms an anti-disengagement constraint after being embedded in the barb groove 5.

[0055] Specifically, when adjacent runway units are joined, the locking block 6 is inserted into the inner cavity of the locking slot 4. Since the size of the locking block 6 matches the inner cavity of the locking slot 4, their contact surfaces form a tight fit. During insertion, the barbed limiting block 7 is squeezed by the side wall of the barbed groove 5. After entering the barbed groove 5, it returns to its original shape through shape adaptation, forming a mechanical limit. Thus, the cooperation between the locking block 6 and the locking slot 4 not only achieves horizontal positioning constraints but also limits the tendency for separation in the vertical direction through the interlocking action of the barbed limiting block 7 and the barbed groove 5.

[0056] Compared to existing technologies, traditional plastic running track splicing structures typically rely on planar contact or simple snap-fit ​​joints, lacking anti-loosening designs. Over long-term use, these connections are prone to loosening due to vibration or external forces. This solution, through the cooperation of barbed grooves 5 and barbed limiting blocks 7, forms a self-locking structure during the snap-fit ​​process. This achieves bidirectional limiting without the need for additional fasteners, significantly improving the connection's resistance to displacement.

[0057] Through the above technical solution, this application solves the technical problem of easy loosening of the splicing structure of plastic running tracks. By utilizing the mechanical interlocking action of the barbed limiting block 7 and the barbed groove 5, displacement of the splicing parts in the horizontal and vertical directions is effectively prevented, ensuring the stability of the overall track structure. At the same time, the size-matching design of the locking block 6 and the locking groove 4 simplifies the installation process, making it easier to achieve precise alignment during splicing.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
