Description

Technical Field

[0001] The present invention relates to the technical field of track plate production, and in particular to a track plate forming method and the track plate. Background Art

[0002] Embedded sleeves are tubular components pre-buried during the track slab production process and are typically used to install track slab fastening systems. Before the track slab is cast, the sleeves must be precisely installed in the designated position within the track slab mold to ensure a tight connection during casting and meet the connection accuracy requirements required during subsequent construction.

[0003] In the existing track slab production process, the sleeve is directly installed in the track slab mold. When pouring concrete into the track slab mold, the concrete will generate impact force on the sleeve during the pouring and vibration process. The sleeve is easily dislocated or damaged under the impact of the concrete, resulting in the installation accuracy of the sleeve being affected, thereby affecting the molding quality of the track slab. Summary of the Invention

[0004] The main purpose of the present invention is to provide a track plate forming method and a track plate, aiming to solve the technical problem in the prior art that the sleeve is easily misplaced or damaged during the casting and vibration process of the track plate, thereby affecting the forming quality of the track plate.

[0006] In one embodiment, the steps of opening a positioning hole at the bottom of the sleeve and cutting a thread on the outer wall of the sleeve include: clamping the sleeve so that the sleeve is placed horizontally, and using a cutting device to cut the sleeve along the axial direction of the sleeve to open the positioning hole at one end of the sleeve; turning the sleeve so that the sleeve is placed vertically, and using the cutting device to cut the sleeve along the circumference of the sleeve to open the thread on the outer wall of the sleeve; roughening the outer wall of the sleeve; and deburring the thread and the positioning hole.

[0007] In one embodiment, the step of bending the steel bars to form spiral bars includes: straightening the steel bars; setting parameters of a CNC winding device according to the pitch of the threads; processing the steel bars according to the set parameters by the CNC winding device to form the spiral bars, so that the pitch of the spiral bars is consistent with the pitch of the threads.

[0008] In one embodiment, the two ends of the spiral rib are respectively a sleeve end and an abutment end, and the radius of the spiral rib is gradually increased from the sleeve end to the abutment end; the step of making a mold of the fixed cylinder according to the outer diameter of the spiral rib includes: making a mold of the fixed cylinder according to the outer diameter of the sleeve end.

[0009] In one embodiment, the step of sleeve-mounting a spiral rib on the outer wall of the sleeve so that the spiral rib extends into the thread includes: sleeve-mounting the spiral rib on the outer wall of the sleeve so that the sleeve end extends into the thread; the step of sleeve-mounting the fixing tube outside the spiral rib to form a pre-embedded sleeve structure includes: sleeve-mounting the fixing tube outside the spiral rib so that the outer side of the abutting end abuts against the inner wall of the fixing tube to form the pre-embedded sleeve structure.

[0010] In one embodiment, before pouring concrete in the track slab mold so that the concrete fits against the outer wall of the fixing tube to bury the embedded sleeve structure in the concrete and form the track slab, the method further includes: installing a steel cage in the track slab mold; and tying and connecting the steel cage and the embedded sleeve structure.

[0011] In one embodiment, the steps of pouring concrete in the track slab mold so that the concrete fits the outer wall of the fixing tube so that the embedded sleeve structure is embedded in the concrete include: applying a release agent to the inner wall of the track slab mold; pouring concrete in the track slab mold so that the concrete fits the outer wall of the fixing tube; vibrating the concrete so that the top surface of the concrete is flush with the top of the fixing tube so that the embedded sleeve structure is embedded in the concrete; and after the concrete is cured and formed, separating the concrete from the track slab mold to form the track slab.

[0012] In one embodiment, before the step of pouring concrete in the track slab mold to make the concrete adhere to the outer wall of the fixing cylinder, the method further comprises: applying a lubricant to the outer wall of the fixing cylinder.

[0013] In one embodiment, after the step of bending the steel bar to form the spiral bar, the method further comprises: coating an anti-corrosion coating on the surface of the spiral bar.

[0014] The present invention also provides a track plate, which is manufactured by the above-mentioned track plate forming method.

[0015] The track plate forming method and track plate proposed in the present invention form a pre-embedded sleeve structure by sequentially sleeve-mounting a sleeve, a spiral rib, and a fixed tube from the inside out. The pre-embedded sleeve structure is installed in the track plate mold before the concrete of the track plate is poured. The fixed tube is formed by pouring concrete. When pouring concrete into the track plate mold, the fixed tube separates the sleeve from the concrete. The fixed tube provides protection for the sleeve to prevent the concrete from directly impacting the sleeve during the pouring and vibrating of the concrete of the track plate, causing displacement or damage to the sleeve. After the concrete solidifies and forms, the concrete of the track plate and the fixed tube are formed into one piece, so that the sleeve is firmly embedded in the track plate and ensures that the sleeve is firmly set. A spiral rib is provided between the sleeve and the fixed tube, and the spiral rib is threadedly engaged with the outer wall of the sleeve, so that the spiral rib is tightly sleeved outside the sleeve. The inner diameter of the fixed tube is consistent with the outer diameter of the spiral rib. When the fixed tube is sleeved outside the spiral rib, the outer side of the spiral rib abuts the inner wall of the fixed tube. The spiral reinforcement has a certain degree of elasticity. During the concrete pouring and vibration process of the track slab, the concrete generates an impact force on the fixed cylinder. The spiral reinforcement absorbs part of the impact force through its own elastic deformation and can disperse and transfer the impact force to all directions of the fixed cylinder, thereby providing protection for the casing, avoiding the casing from being directly impacted and causing displacement, ensuring the position of the casing is fixed during the concrete pouring process, ensuring the accurate installation of the casing, effectively improving the installation accuracy of the casing, and thus improving the molding quality of the track slab.

[0028] In the existing track slab production process, the sleeve is directly installed in the track slab mold. When pouring concrete into the track slab mold, the concrete will generate impact force on the sleeve during the pouring and vibration process. The sleeve is easily dislocated or damaged under the impact of the concrete, resulting in the installation accuracy of the sleeve being affected, thereby affecting the molding quality of the track slab.

[0029] The present invention provides a method for forming a track plate, comprising the steps of:

[0030] S10: opening a positioning hole at the bottom of the sleeve and cutting the outer wall of the sleeve to form a thread;

[0031] S20: bending the steel bar to form a spiral bar;

[0032] S30: arranging a spiral rib on the outer wall of the sleeve so that the spiral rib extends into the thread;

[0033] S40: Making a mold for a fixed cylinder according to the outer diameter of the spiral rib;

[0034] S50: pouring concrete into the mold of the fixing tube to form the fixing tube; the inner diameter of the fixing tube is consistent with the outer diameter of the spiral reinforcement;

[0035] S60: Sleeve the fixing tube onto the spiral rib to form a pre-buried sleeve structure;

[0036] S70: Installing the embedded sleeve structure in the track plate mold so that the positioning hole is plugged into and matched with the positioning pin in the track plate mold;

[0037] S80: pouring concrete in the track slab mold to make the concrete fit the outer wall of the fixing tube, so as to embed the embedded sleeve structure in the concrete and form the track slab.

[0038] See also Figure 1 、 Figure 4 and Figure 5 , Figure 1 A schematic flow chart of an embodiment of a track plate forming method provided by the present invention; Figure 4 This is a structural schematic diagram of the embedded sleeve structure installed in the track plate mold in the track plate forming method provided by the present invention; Figure 5 This is a schematic diagram of the structure of an embodiment of the embedded sleeve structure in the track slab forming method provided by the present invention. Before installing the sleeve 11 on the track slab mold 20, a positioning hole is opened at the bottom of the sleeve 11, a thread 12 is opened on the outside of the sleeve 11, and the spiral rib 13 is screwed into the thread 12 so that the spiral rib 13 is sleeved on the outside of the sleeve 11. Then, a fixed cylinder 14 made of concrete is sleeved on the outside of the spiral rib 13, so that the sleeve 11, spiral rib 13, and fixed cylinder 14 are sleeved in sequence from the inside to the outside to form the embedded sleeve structure 10. Finally, the embedded sleeve structure 10 is installed on the track slab mold 20 by plugging and matching the positioning holes with the positioning pins in the track slab mold 20. It should be noted that the spiral rib 13 has a certain degree of elasticity. When the fixed cylinder 14 squeezes the spiral rib 13, the spiral rib 13 can produce elastic deformation in its radial direction relative to the sleeve 11. When pouring concrete in the track slab mold 20, the concrete is made to fit the outer wall of the fixed cylinder 14. After the concrete is poured and formed, the concrete and the fixing tube 14 are connected as a whole, and together the spiral reinforcement 13 and the sleeve 11 are buried in the track plate, thereby completing the shaping of the track plate.

[0039] The track plate forming method proposed in the present invention forms a pre-embedded sleeve structure 10 by sequentially sleeve-mounting a sleeve 11, a spiral rib 13, and a fixed cylinder 14 from the inside out. Before the concrete of the track plate is poured, the pre-embedded sleeve structure 10 is installed in the track plate mold 20. The fixed cylinder 14 is formed by pouring concrete. When pouring concrete into the track plate mold 20, the fixed cylinder 14 separates the sleeve 11 from the concrete. The fixed cylinder 14 provides protection for the sleeve 11 to prevent the sleeve 11 from being displaced or damaged by direct impact of the concrete during the pouring and vibration of the track plate. After the concrete solidifies and forms, the concrete of the track plate and the fixed cylinder 14 are formed into one body to firmly embed the sleeve 11 in the track plate, ensuring that the sleeve 11 is firmly set. By providing a spiral rib 13 between the sleeve 11 and the fixed tube 14, the spiral rib 13 cooperates with the thread 12 on the outer wall of the sleeve 11, so that the spiral rib 13 is tightly sleeved on the outside of the sleeve 11, and the inner diameter of the fixed tube 14 is consistent with the outer diameter of the spiral rib 13. When the fixed tube 14 is sleeved on the outside of the spiral rib 13, the outer side of the spiral rib 13 abuts the inner wall of the fixed tube 14. The spiral rib 13 has a certain degree of elasticity. During the concrete pouring and vibration process of the track slab, the concrete generates an impact force on the fixed tube 14. The spiral rib 13 absorbs part of the impact force through its own elastic deformation and can disperse the impact force in all directions of the fixed tube 14, thereby providing protection for the sleeve 11, preventing the sleeve 11 from being directly impacted and causing displacement, ensuring the fixed position of the sleeve 11 during the concrete pouring process, ensuring the accurate installation of the sleeve 11, and effectively improving the installation accuracy of the sleeve 11, thereby improving the molding quality of the track slab.

[0040] In one embodiment, step S10 includes:

[0041] S11: clamping the sleeve, placing the sleeve in a transverse direction, and using a cutting device to cut the sleeve along the axial direction of the sleeve to open the positioning hole at one end of the sleeve;

[0042] S12: turning over the casing to place it vertically, and using the cutting device to cut the casing along the circumference of the casing to open the thread on the outer wall of the casing;

[0043] S13: performing roughening treatment on the outer wall of the sleeve;

[0044] S14: Deburring the threads and the positioning holes.

[0045] See also Figure 2 , Figure 2 for Figure 1Detailed flow diagram of step S10 in the process; when processing the sleeve 11, the sleeve 11 is first clamped horizontally and cut along the axial direction of the sleeve 11 using a cutting device to create a positioning hole at one end of the sleeve 11. The sleeve 11 is then clamped longitudinally and cut along the circumference of the sleeve 11 using a cutting device to create a thread 12 on the outer wall of the sleeve 11. The outer wall of the sleeve 11 is then roughened. Finally, the thread 12 and the positioning hole are deburred. By clamping and cutting horizontally first and then longitudinally, the positioning hole and thread 12 can be accurately processed, ensuring processing accuracy and quality. The roughening treatment can improve the bonding strength between the outer wall of the sleeve 11 and the subsequent spiral ribs 13 and the fixing tube 14, and the deburring treatment is beneficial to the assembly and installation of subsequent components, avoiding the adverse effects of burrs on the fit of various components and the pouring of concrete. Overall, it improves the processing quality and assembly reliability of the embedded sleeve structure 10 during the track plate forming process, thereby helping to improve the forming quality and performance of the track plate.

[0046] In one embodiment, step S20 includes:

[0047] S21: straightening the steel bars;

[0048] S22: Setting parameters of a CNC winding device according to the pitch of the threads;

[0049] S23: Processing the steel bar according to set parameters by the CNC winding device to form the spiral bar, so that the pitch of the spiral bar is consistent with the pitch of the thread.

[0050] See also Figure 3 , Figure 3 for Figure 1 Detailed flow chart of step S20; since the steel bars are usually housed on a reel, the steel bars are first straightened before being bent so that the bending stress of the steel bars caused by the reeling is gradually eliminated to ensure the accuracy of subsequent processing; then the corresponding parameters of the CNC winding equipment are set according to the pitch of the thread 12 so that the equipment can perform the winding operation according to the required pitch; then the straightened steel bars are wound according to the set parameters by the CNC winding equipment to form a spiral rib 13, and the pitch of the spiral rib 13 is consistent with the pitch of the thread 12, thereby ensuring that the spiral rib 13 can accurately match the thread 12, so that the spiral rib 13 is tightly and evenly wound on the outer wall of the sleeve 11. By accurately controlling the pitch of the spiral rib 13 through the CNC winding equipment, the quality and dimensional accuracy of the spiral rib 13 can be effectively guaranteed, thereby improving the assembly accuracy and stability of the embedded sleeve structure 10, which is conducive to improving the reliability and quality of the entire track plate forming.

[0051] In one embodiment, the two ends of the spiral rib 13 are respectively a sleeve end 131 and an abutment end 132 , and the radius of the spiral rib 13 gradually increases from the sleeve end 131 to the abutment end 132 ;

[0052] Step S40 includes:

[0053] S41: making a mold of the fixing cylinder according to the outer diameter of the sleeve end.

[0054] Step S30 includes:

[0055] S31: sleeve the spiral rib on the outer wall of the sleeve so that the sleeve end extends into the thread;

[0056] Step S60 includes:

[0057] S61: Sleeve the fixing tube outside the spiral rib so that the outer side of the abutting end abuts against the inner wall of the fixing tube to form the embedded sleeve structure.

[0058] It should be noted that the top of the spiral rib 13 is the sleeve end 131, and the bottom is the abutment end 132. The radius of the spiral rib 13 is gradually increased from the top to the bottom, and the diameter of the fixed tube 14 is consistent with the bottom outer diameter of the spiral rib 13. When the spiral rib 13 is sleeved outside the sleeve 11, the top of the spiral rib 13 cooperates with the thread 12 on the sleeve 11, and the bottom of the spiral rib 13 abuts against the inner wall of the fixed tube 14, so that the spiral rib 13 can form a gradient elastic structure along the radial direction, and can produce different degrees of elastic deformation according to the change of the impact force of the concrete, which is beneficial to absorb the impact force, thereby providing protection for the sleeve 11 and ensuring the stable setting of the sleeve 11.

[0059] In one embodiment, before step S80, the track plate forming method provided by the present invention further includes the following steps:

[0060] S78: Installing a steel cage in the track slab mold;

[0061] S79: Tie and connect the steel cage and the embedded sleeve structure.

[0062] It is understood that the steel cage is installed within the track slab mold 20, serving as the track slab's skeletal support, tightly integrating the steel cage with the concrete to form a reinforced concrete structural system. The steel cage and the embedded casing structure 10 are connected by binding at their contact points, ensuring that the steel cage and the embedded casing structure 10 do not move relative to each other during the concrete pouring process, ensuring that the embedded casing structure 10 is fixed in its installation position, thereby improving the installation accuracy of the casing 11 and enhancing the overall structural stability of the track slab.

[0063] In one embodiment, step S80 includes:

[0064] S81: Applying a release agent to the inner wall of the track plate mold;

[0065] S82: pouring concrete into the track slab mold so that the concrete fits the outer wall of the fixing cylinder;

[0066] S83: vibrating the concrete so that the top surface of the concrete is flush with the top of the fixing tube, so as to embed the embedded sleeve structure in the concrete;

[0067] S84: After the concrete is cured and formed, the concrete is separated from the track slab mold to form the track slab.

[0068] It should be noted that before pouring concrete into the track slab mold 20, a release agent is applied to the inner wall of the track slab mold 20 to facilitate separation of the concrete from the track slab mold 20 after forming, thereby ensuring the surface quality of the track slab. When pouring concrete into the track slab mold 20, the concrete is tightly fitted to the outer wall of the fixed tube 14 of each embedded sleeve structure 10. Vibrating the concrete eliminates bubbles and voids within the concrete, improving the density of the concrete. After the volume of the concrete stabilizes, the top surface of the concrete is aligned with the top of the fixed tube 14. After the concrete solidifies, the concrete and the fixed tube 14 are formed into one piece, so that the sleeve 11 is embedded in the track slab, ensuring the secure placement of the sleeve 11.

[0069] In one embodiment, before step S82, the track plate forming method provided by the present invention further includes the following steps:

[0070] S819: Apply lubricant to the outer wall of the fixed cylinder.

[0071] It should be explained that before pouring concrete into the track plate mold 20, a lubricant is applied to the outer wall of the fixed cylinder 14 in advance. After the concrete is poured, the lubricant keeps the concrete and the outer wall of the fixed cylinder 14 lubricated, and the concrete and the outer wall of the fixed cylinder 14 fit together but are not directly connected. As the concrete of the track plate solidifies and forms, the volume of the concrete changes to a certain extent, while the fixed cylinder 14, as a pre-formed concrete structure, remains fixed in volume. By applying lubricant to the contact surface between the concrete of the track plate and the fixed cylinder 14, the solidification of the concrete of the fixed cylinder 14 and the track plate does not interfere with each other during the solidification and forming process of the concrete, effectively improving the forming quality of the contact surface between the concrete and the fixed cylinder 14; after the concrete solidifies and forms, the lubricant gradually loses its effectiveness due to dilution, so that the formed concrete is tightly connected to the outer wall of the fixed cylinder 14 and forms an integrated structure, ensuring that the track plate is tightly connected to the embedded sleeve structure 10 and that the sleeve 11 structure is firmly set in the track plate.

[0072] In one embodiment, after step S20, the track plate forming method provided by the present invention further comprises the following steps:

[0073] S201: applying an anti-corrosion coating on the surface of the spiral rib.

[0074] It should be noted that after the track slab is cast, the space between the spiral rib 13 and the sleeve 11 can be filled with concrete or other filling material. By applying an anti-corrosion coating to the surface of the spiral rib 13, the spiral rib 13, when embedded in the filling material, can effectively slow down the rate of corrosion of the spiral rib 13 by the filling material, thereby extending the service life of the spiral rib 13 and the track slab. The anti-corrosion coating adopts the anti-corrosion coating of the prior art and can be flexibly set according to the specific filling material selected.

[0075] In one embodiment, the fixing cylinder and the track slab have the same concrete grade.

[0076] It can be understood that the fixing cylinder 14 is cast in advance, and the material of the fixing cylinder 14 and the material of the track plate are selected from concrete of the same grade, so that the concrete of the track plate and the fixing cylinder 14 have good compatibility. After the concrete of the track plate is formed, the concrete and the fixing cylinder 14 can be better combined into one, avoiding problems such as stress concentration or interface peeling due to differences in material properties, which helps to improve the overall structural strength of the track plate.

[0077] The present invention also proposes a track plate, which is manufactured and formed using the above-mentioned track plate forming method. The specific structure of the track plate forming method refers to the above-mentioned embodiment. Since the track plate adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0078] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformation made by using the contents of the present invention description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the scope of protection of the present invention.
