Description

Technical Field

[0001] The present invention relates to the field of plastic runways, and in particular to a modular plastic runway assembly that is easy to lay and a laying method thereof. Background Art

[0002] A synthetic rubber track is a sports surface made of synthetic rubber, commonly used in track and field sports. The surface provides a certain degree of elasticity and resistance, which aids athlete performance while also reducing the impact of running or jumping, minimizing the risk of injury.

[0003] In order to achieve the purpose of easy installation and maintenance, modular plastic tracks, also known as prefabricated plastic tracks, have now appeared. They are a type of plastic track that is first manufactured into modules of a certain size in a factory and then assembled at the installation site.

[0004] Now, the disadvantage of modular plastic tracks is that the runway as a whole is made up of modular plastic tracks. Due to the modularity, there will be gaps between the individual modular plastic tracks. In rainy weather, rainwater will accumulate in the gaps and is difficult to drain. Over time, the plastic track is prone to bulging and mold due to long-term water accumulation, which seriously reduces the service life of the plastic track.

[0005] Based on this, the present invention provides a modular plastic track assembly that is easy to lay, so as to improve the drainage performance of the modular plastic track and solve the problem of water accumulation on the modular plastic track. Summary of the Invention

[0006] Based on this, on the one hand, the present invention provides a modular plastic track component that is easy to lay, including modular monomers for forming a track and mounting columns for installing the modular monomers; the modular monomers include an asphalt base layer and a functional layer arranged from bottom to top and connected to each other, the asphalt base layer is in a square shape, the functional layer has a lower surface, an upper surface and four side walls, the lower surface of the functional layer is connected to the upper surface of the asphalt base layer, and the upper surface of the functional layer is arranged horizontally; the four side walls of the functional layer are arranged corresponding to the four side walls of the asphalt base layer, which are two vertical walls and Two inclined walls, the vertical wall is flush with the corresponding side wall of the asphalt base layer, forming a square vertical plane with the corresponding side wall of the asphalt base layer, the upper end and the lower end of the inclined wall are parallel to the corresponding side wall of the asphalt base layer, and the upper end and the lower end of the inclined wall are respectively located on the outside and the inside of the corresponding side wall of the asphalt base layer; a receiving groove is vertically provided in the middle position of all the side walls of the asphalt base layer, the receiving groove is semi-cylindrical, and the receiving groove passes through the asphalt base layer from top to bottom; the mounting column is hollow cylindrical, and the outer diameter of the mounting column is the same as the diameter of the receiving groove.

[0007] In the present invention, modular units are used to be spliced ​​together to form a plastic track. After the modular units are spliced ​​together to form the plastic track, they need to be installed on mounting posts to complete the laying of the plastic track on the ground. When splicing the plastic track, the modular units need to be oriented in the same direction. For example, the sidewalls of each modular unit with an inclined wall are located on the rear and right sides of the modular unit. At the same time, the sidewalls of the asphalt base layers of the modular units need to be aligned with each other.

[0008] In the present invention, after the modular units are assembled into a plastic runway, the receiving grooves on the modular units will be assembled into cylindrical grooves. The specific process of installing the assembled plastic runway on the mounting column is as follows: after the mounting column is inserted into the ground, the cylindrical groove on the plastic runway assembled from the modular units is sleeved on the top of the mounting column so that the top of the mounting column abuts against the functional layer. At the same time, molten asphalt needs to be filled between the ground and the plastic runway to bond the modular units and the ground together after the filled asphalt cools and solidifies.

[0009] In the present invention, the high temperature of the filled asphalt will melt part of the asphalt layer of the modular monomer (especially the lower surface of the asphalt layer in contact with the molten asphalt and the side wall of the asphalt layer), so that the asphalt layers of adjacent modular monomers can be fused together while bonding the modular monomers to the ground, and the asphalt layers and the installation columns can be bonded together. At this time, each asphalt layer in the plastic track will form a barrier layer with an upper surface flush with the upper end of the installation column, and moisture entering the gap between adjacent modular monomers cannot pass through the barrier layer. At the same time, in the present invention, the plastic track is spliced ​​together. The side walls of the asphalt base layer of the modular units of the track fit together, and because the upper ends of the inclined walls of the functional layer extend outward from the outside of the asphalt base layer, the upper ends of the inclined walls and the vertical walls of adjacent modular units will press against each other, forming a relatively closed closed cavity with the barrier layer. At this time, when the plastic track is in use, the footsteps acting on the plastic track will squeeze the closed cavity. During the squeezing process, the pushed airflow will drive the rainwater accumulated in the closed cavity to flow toward the hollow cylindrical installation column, so that the rainwater leaves the plastic track through the installation column and enters the ground soil. It can be seen that the present invention has the function of actively draining the water accumulated in the gaps, that is, the present invention can solve the problem of water accumulation in the gaps of the plastic track for a long time, and can effectively prevent the modular plastic track from bulging and moldy due to long-term water accumulation, thereby effectively improving the service life of the modular plastic track.

[0010] In addition, in the present invention, since the upper ends of the inclined walls and the vertical walls of adjacent modular units are pressed against each other, there will be a certain sealing effect between the upper ends of the inclined walls and the vertical walls. When the modular plastic track is used after the rain, the moisture accumulated in the closed cavity cannot splash out from the gap, which can effectively improve the user experience of the modular plastic track after the rain.

[0011] Furthermore, the functional layer includes an elastic layer and a surface layer arranged from bottom to top.

[0012] In the present invention, the elastic layer and surface layer of the modular unit can be made of the same materials as the elastic layer and surface layer of a conventional plastic track. For example, the elastic layer is made of a mixture of rubber particles and an adhesive to provide a vibration damping effect and elastic properties, and the surface layer is made of a mixture of rubber particles and an adhesive such as polyurethane or polyethylene to provide a smooth and soft surface, as well as good anti-slip and wear resistance.

[0013] Furthermore, the angle between the inclined wall and the vertical direction is 5°-10°.

[0014] In the present invention, the inclined wall angle of 5°-10° can ensure that the edges of the modular unit have good structural strength and support strength, and will not collapse during use. It can also ensure that the closed cavity has sufficient space and that the airflow generated when the closed cavity is squeezed is sufficient to push the rainwater in the closed cavity to flow toward the support column.

[0015] Furthermore, the upper end of the mounting post is horizontal, and the lower end of the mounting post is pointed.

[0016] In the present invention, the sharp lower end of the mounting post can be easily inserted into the ground, and the horizontal upper end of the mounting post can provide better support for the modular unit.

[0017] Furthermore, the outer surface of the mounting post is marked with a first marking line, and the distance between the first marking line and the top end of the mounting post is the height of the accommodating groove.

[0018] In the present invention, the distance between the first marking line on the mounting column and the top of the mounting column is the height of the receiving groove, which is used to mark the height to be filled with asphalt. During the asphalt paving process, it can be observed whether the asphalt has been paved to the preset height, which can eliminate the need for measuring the asphalt height during the asphalt paving process, thereby facilitating the asphalt paving process.

[0019] Furthermore, the outer surface of the mounting post is also marked with a second marking line, and the second marking line is located below the first marking line.

[0020] In the present invention, the second marking line on the outer surface of the mounting column is used to mark the insertion depth of the mounting column in the ground, so as to facilitate the judgment of whether the mounting column is inserted into place during the insertion process of the mounting column. Preferably, when the second marking line is flush with the ground, the mounting column has reached the preset insertion depth.

[0021] In another aspect, the present invention provides a method for laying the aforementioned modular plastic track assembly that is easy to lay, comprising the following steps:

[0022] Positioning of mounting posts:

[0023] The position data of the cylindrical groove formed by assembling the receiving grooves on the modular monomers after the modular monomers are assembled into the plastic track are calculated based on the shapes and specifications of the modular monomers. The modular monomers are assembled into the plastic track in such a manner that the modular monomers are assembled in the same direction and the side walls of the base layers on the modular monomers are affixed to each other when the modular monomers are assembled.

[0024] Laying modular monomers:

[0025] S1. Dig a runway-shaped recessed structure for laying the plastic track at the runway paving location, then level the bottom surface of the recessed structure and insert the mounting posts into the bottom surface of the recessed structure. When inserting the mounting posts, ensure that the lengths of the posts exposed above the ground are the same and that the posts are arranged according to the position data of the cylindrical grooves.

[0026] The bottom surface of the concave structure is the ground inside the concave structure, and the installation columns are arranged according to the position data of the cylindrical grooves, which means that the installation columns correspond one-to-one with the cylindrical grooves on the assembled plastic track, and all the installation columns can be inserted into the corresponding cylindrical grooves at the same time;

[0027] S2. Pour the heated molten asphalt into the recessed structure. After the pouring is completed, the distance between the asphalt surface and the top of the installation column must be the same as the thickness of the modular single asphalt layer.

[0028] S3. Lay the modular units one by one to form a plastic track. When laying, the receiving grooves of the modular units need to be placed on the tops of the mounting columns, and the tops of the mounting columns need to be in contact with the elastic layers of the modular units.

[0029] Among them, when pouring molten asphalt, the distance between the asphalt surface and the top of the installation column is made the same as the thickness of the modular monomer asphalt layer. After the modular monomer is installed on the installation column, the asphalt layer of the modular monomer just contacts the molten asphalt, which facilitates the fusion and bonding of the asphalt layer and the molten asphalt.

[0030] S4. Use a heavy object to press on the plastic track made of modular units for a while, waiting for the asphalt to cool and solidify;

[0031] Among them, the weight is preferably a plate-shaped weight, and preferably spans the entire plastic track along the width direction of the plastic track, so that each modular unit is subjected to approximately the same pressure, ensuring the flatness of the plastic track after the asphalt cools and solidifies.

[0032] Furthermore, the process of steps S2-S4 is repeated in sections along the direction of the plastic track.

[0033] In the present invention, the specific operation of repeating in sections is: after completing the excavation of the sunken structure, use two partitions to block out an area in the sunken structure, and gradually complete steps S2-S4 in the area, and then use another partition to block out another area from the area where steps S2-S4 are completed, and then gradually complete steps S2-S4 again in the area, and so on, until the entire modular plastic track is laid.

[0034] Among them, steps S2-S4 are performed in a segmented and repeated manner, so that the paving of the corresponding modular monomers can be completed as soon as possible after the pouring of the molten asphalt is completed, so that after the laying of the corresponding modular monomers is completed, the molten asphalt can maintain a sufficient temperature to partially melt the asphalt layer of the modular monomer, thereby ensuring that the asphalt layer can fuse and bond with the molten asphalt, and the asphalt layers can fuse and bond with each other.

[0035] The principle and effect of the present invention are further explained below in conjunction with the above technical solutions and the accompanying drawings:

[0036] In the present invention, the upper ends of the inclined walls and the vertical walls of adjacent modular units press against each other, forming a relatively closed cavity with the barrier layer. At this time, when the plastic runway is in use, the footsteps acting on the plastic runway will squeeze the closed cavity. During the squeezing process, the pushed airflow will drive the rainwater accumulated in the closed cavity to flow toward the hollow cylindrical mounting posts, so that the rainwater leaves the plastic runway through the mounting posts and enters the ground soil. It can be seen that the present invention has the function of actively draining the water accumulated in the gaps. That is, the present invention can solve the problem of long-term water accumulation in the gaps of the plastic runway, and can effectively prevent the modular plastic runway from bulging and mold due to long-term water accumulation, thereby effectively extending the service life of the modular plastic runway.

[0046] To facilitate understanding by those skilled in the art, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments:

[0047] like Figure 1-7 , a modular plastic track component that is easy to lay, including a modular monomer 1 for forming a runway and a mounting column 2 for installing the modular monomer 1; the modular monomer 1 includes an asphalt base layer 11 and a functional layer arranged from bottom to top and connected to each other, the asphalt base layer 11 is square-shaped, the functional layer has a lower surface, an upper surface and four side walls, the lower surface of the functional layer is connected to the upper surface of the asphalt base layer 11, and the upper surface of the functional layer is horizontally arranged; the four side walls of the functional layer correspond to the four side walls of the asphalt base layer 11, respectively, two vertical walls 123 and two inclined walls 124, the vertical The wall 123 is arranged flush with the corresponding side wall of the asphalt base layer 11, forming a square vertical plane with the corresponding side wall of the asphalt base layer 11, the upper end and the lower end of the inclined wall 124 are arranged parallel to the corresponding side wall of the asphalt base layer 11, and the upper end and the lower end of the inclined wall 124 are respectively located on the outside and the inside of the corresponding side wall of the asphalt base layer 11; a receiving groove is vertically provided in the middle position of all the side walls of the asphalt base layer 11, the receiving groove is semi-cylindrical, and the receiving groove is arranged to pass through the asphalt base layer 11 from top to bottom; the mounting column 2 is a hollow circular tube, and the outer diameter of the mounting column 2 is the same as the diameter of the receiving groove.

[0048] In the present invention, modular units 1 are used to be spliced ​​together to form a plastic track. After the modular units 1 are spliced ​​together to form the plastic track, they need to be installed on the mounting posts 2 to complete the laying of the plastic track on the ground. When splicing the plastic track, it is necessary to ensure that the orientation of each modular unit 1 is the same. For example, the side wall of each modular unit 1 having the inclined wall 124 is located on the rear and right side of the modular unit 1. At the same time, it is also necessary to ensure that the side walls of the asphalt base layer 11 of the modular units 1 are in contact with each other.

[0049] In the present invention, after the modular units 1 are assembled into a plastic track, the receiving grooves on the modular units 1 will be assembled into cylindrical grooves. The specific process of installing the assembled plastic track on the mounting column 2 is as follows: after the mounting column 2 is inserted into the ground, the cylindrical groove on the plastic track assembled by the modular units 1 is sleeved on the top of the mounting column 2, so that the top of the mounting column 2 abuts against the functional layer. At the same time, molten asphalt needs to be filled between the ground and the plastic track so that the modular units 1 and the ground can be bonded together after the filled asphalt cools and solidifies.

[0050] In the present invention, the high temperature of the filled asphalt will melt part of the asphalt layer of the modular monomer 1 (especially the lower surface of the asphalt layer in contact with the molten asphalt and the side wall of the asphalt layer), so that the asphalt layers of adjacent modular monomers 1 can be fused together while bonding the modular monomer 1 to the ground, and the asphalt layer and the mounting column 2 can be bonded together. At this time, each asphalt layer in the plastic track will form a barrier layer with an upper surface flush with the upper end of the mounting column 2, and moisture entering the gap between adjacent modular monomers 1 cannot pass through the barrier layer. At the same time, in the present invention, the modular monomers spliced ​​into the plastic track The side walls of the asphalt base layer 11 of the functional layer 1 are in contact with each other, and because the upper ends of the inclined walls 124 of the functional layer extend beyond the outer side of the asphalt base layer 11, the upper ends of the inclined walls 124 and the vertical walls 123 of the adjacent modular units 1 are pressed against each other, forming a relatively closed closed cavity 3 with the barrier layer. At this time, when the plastic runway is in use, the footsteps acting on the plastic runway will squeeze the closed cavity 3. During the squeezing process, the pushed airflow will drive the rainwater accumulated in the closed cavity 3 to flow toward the hollow cylindrical mounting post 2, so that the rainwater leaves the plastic runway through the mounting post 2 and enters the ground soil. It can be seen that the present invention has the function of actively draining water accumulated in the gaps, that is, the present invention can solve the problem of long-term water accumulation in the gaps of the plastic runway, and can effectively prevent the modular plastic runway from bulging and mold due to long-term water accumulation, thereby effectively extending the service life of the modular plastic runway.

[0051] In addition, in the present invention, since the upper ends of the inclined walls 124 and the vertical walls 123 of adjacent modular units 1 are pressed against each other, there is a certain sealing effect between the upper ends of the inclined walls 124 and the vertical walls 123. When the modular plastic track is used after the rain, the moisture accumulated in the closed cavity 3 cannot splash out from the gap, which can effectively improve the user experience of the modular plastic track after the rain.

[0052] In one embodiment, the functional layer includes an elastic layer 121 and a surface layer 122 arranged from bottom to top.

[0053] In this embodiment, the elastic layer 121 and the surface layer 122 of the modular unit 1 can be made of the same materials as the elastic layer 121 and the surface layer 122 of a conventional plastic track. For example, the elastic layer 121 is made of a mixture of rubber particles and an adhesive to provide a vibration reduction effect and elastic properties, and the surface layer 122 is made of a mixture of rubber particles and an adhesive such as polyurethane or polyethylene to provide a smooth and soft surface, as well as good anti-slip and wear resistance.

[0054] In one embodiment, the angle between the inclined wall 124 and the vertical direction is 5°-10°.

[0055] In this embodiment, the 5°-10° inclination angle of the inclined wall 124 can ensure that the edge of the modular unit 1 has good structural strength and support strength, and will not collapse during use. It can also ensure that the closed cavity 3 has sufficient space and that the airflow generated when the closed cavity 3 is squeezed is sufficient to push the rainwater in the closed cavity 3 to flow toward the support column.

[0056] In one embodiment, the upper end of the mounting post 2 is horizontal, and the lower end of the mounting post 2 is pointed.

[0057] In this embodiment, the sharp lower end of the mounting post 2 can be easily inserted into the ground, and the horizontal upper end of the mounting post 2 can provide better support for the modular unit 1.

[0058] In one embodiment, the outer surface of the mounting post 2 is marked with a first identification line 21 , and the distance between the first identification line 21 and the top end of the mounting post 2 is the height of the accommodating groove.

[0059] In this embodiment, the distance between the first marking line 21 on the mounting column 2 and the top of the mounting column 2 is the height of the receiving groove, which is used to mark the height to which the asphalt needs to be filled. During the asphalt paving process, it can be observed whether the asphalt has been paved to the preset height, which can eliminate the need to measure the asphalt height during the asphalt paving process, thereby facilitating the asphalt paving process.

[0060] In one embodiment, the outer surface of the mounting post 2 is further marked with a second marking line 22 , and the second marking line 22 is located below the first marking line 21 .

[0061] In this embodiment, the second identification line 22 on the outer surface of the mounting column 2 is used to identify the insertion depth of the mounting column 2 in the ground, so as to facilitate the judgment of whether the mounting column 2 is inserted into place during the insertion process of the mounting column 2. Preferably, when the second identification line 22 is flush with the ground, the mounting column 2 has reached the preset insertion depth.

[0062] In one embodiment, the present invention provides a method for laying the aforementioned modular plastic track assembly that is easy to lay, comprising the following steps:

[0063] Positioning of mounting column 2:

[0064] The position data of the cylindrical groove formed by the receiving grooves on the modular monomers 1 after the modular monomers 1 are assembled into a plastic track are calculated based on the shape and specifications of the modular monomers 1. The modular monomers 1 are assembled into a plastic track in such a manner that the modular monomers 1 are assembled together in the same direction and the side walls of the base layers on the modular monomers 1 are affixed together when the modular monomers 1 are assembled.

[0065] Laying modular monomer 1:

[0066] S1. Dig a runway-shaped recessed structure for laying the plastic runway at the runway paving location, then level the bottom surface of the recessed structure and insert the mounting posts 2 into the bottom surface of the recessed structure. When inserting the mounting posts 2, it is necessary to ensure that the lengths of the mounting posts 2 exposed above the ground are the same and that the mounting posts 2 are arranged according to the position data of the cylindrical groove;

[0067] The bottom surface of the concave structure is the ground inside the concave structure, and the mounting posts 2 are arranged according to the position data of the cylindrical grooves, which means that the mounting posts 2 correspond one-to-one with the cylindrical grooves on the assembled plastic track, and all the mounting posts 2 can be inserted into the corresponding cylindrical grooves at the same time;

[0068] S2. Pour the heated molten asphalt into the recessed structure. After the pouring is completed, the distance between the asphalt surface and the top of the installation column 2 must be the same as the thickness of the asphalt layer of the modular unit 1.

[0069] S3. Lay the modular units 1 one by one to form a plastic track. During the laying process, the receiving grooves of the modular units 1 need to be placed on the tops of the mounting posts 2, and the tops of the mounting posts 2 need to abut against the elastic layers 121 of the modular units 1.

[0070] When pouring molten asphalt, the distance between the asphalt surface and the top of the mounting column 2 is made the same as the thickness of the asphalt layer of the modular monomer 1. After the modular monomer 1 is installed on the mounting column 2, the asphalt layer of the modular monomer 1 just contacts the molten asphalt, which facilitates the fusion and bonding of the asphalt layer and the molten asphalt.

[0071] S4. Use a heavy object to press on the plastic track assembled from modular units 1 for a period of time, waiting for the asphalt to cool and solidify;

[0072] Among them, the weight is preferably a plate-shaped weight, and preferably spans the entire plastic track along the width direction of the plastic track, so that each modular unit 1 is subjected to approximately the same pressure, ensuring the flatness of the plastic track after the asphalt is cooled and solidified.

[0073] In one embodiment, the process of steps S2-S4 is repeated in sections along the direction of the plastic track.

[0074] In this embodiment, the specific operations repeated in sections are: after completing the excavation of the sunken structure, use two partitions to block off an area in the sunken structure, and gradually complete steps S2-S4 within the area, and then use another partition to block off another area from the area where steps S2-S4 are completed, and then gradually complete steps S2-S4 again within the area, and so on, until the entire modular plastic track is laid.

[0075] Among them, steps S2-S4 are performed in a segmented and repeated manner, so that the paving of the corresponding modular monomer 1 can be completed as soon as possible after the pouring of the molten asphalt is completed, so that after the laying of the corresponding modular monomer 1 is completed, the molten asphalt can maintain a sufficient temperature to partially melt the asphalt layer of the modular monomer 1, thereby ensuring that the asphalt layer can be fused and bonded with the molten asphalt, and the asphalt layers can be fused and bonded with each other.

[0076] The above embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
