Description

Technical Field

[0001] This application relates to the field of ballastless track system technology, specifically to a construction method for a CRTSⅢ type base plate force transmission pad. Background Technology

[0002] With the development of high-speed railways, the CRTSⅢ type slab track system has become a new type of system for construction on passenger dedicated lines. Due to its advantages such as high stability, good stiffness uniformity, and strong structural durability, ballastless track construction technology is being widely adopted on more and more passenger dedicated lines.

[0003] In this system, a force-transmitting pad is installed between two adjacent base plates. The force-transmitting pad is a key component, and its core functions include: transmitting longitudinal loads to coordinate the stress on the track structure under train operation (starting, braking, acceleration and deceleration) and temperature changes; allowing small relative expansion and contraction deformations between adjacent base plate sections to avoid cracking caused by temperature stress; ensuring the integrity and stability of the track structure; and limiting lateral displacement to maintain the stability of the track direction.

[0004] However, refer to Figure 6 and Figure 7 As shown, the construction of load transfer pads in the existing technology has significant defects: In order to facilitate the alignment of the base plate templates on both sides, the length of the load transfer pad is usually slightly shorter than the width of the base plate, and it mainly relies on top suspension for positioning. This setting results in the load transfer pad not being able to completely cover the joint area of ​​the base plate at both ends, causing the load transfer function in this area to be lost. Consequently, the concrete at the edge of the unprotected base plate is very prone to cracking under stress. At the same time, this construction method cannot guarantee the flatness of the load transfer pad, and wrinkles are very likely to occur, resulting in a reduction in the effective contact area. Stress concentration will form at the wrinkles, which will not only significantly reduce the load transfer pad's ability and efficiency to transfer shear force, but also accelerate the fatigue cracking, hardening and permanent deformation of the load transfer pad, thus accelerating the overall aging, deterioration and failure of the pad. In addition, wrinkles will destroy the flatness and tightness of the contact surface between the load transfer pad and the concrete, forming water seepage channels, resulting in weakened or even lost waterproof sealing function.

[0025] A clamping part is disposed on the side of the force transmission pad away from the fixing plate, and the clamping part extends along a first direction; the first direction is parallel to the length direction of the force transmission pad;

[0030] Compared with the prior art, the beneficial effects of this application are as follows:

[0031] This application provides a construction method for a CRTSⅢ type base plate force transmission pad. First, the laying positions of two adjacent base plate sections are determined, and a pair of base plate templates are erected corresponding to each laying position. A forming space is formed between the pair of base plate templates, and a first gap is formed at the joint of two adjacent base plate templates on the same side.

The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application.

[0044] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0045] To make the technical solution of this application clearer and easier to understand, the construction method of a CRTSⅢ type base plate force transmission pad provided in the embodiment of this application is described below.

[0046] like Figure 1 As shown in the figure, this embodiment provides a construction method for a CRTSⅢ type base plate force transmission pad, which includes the following steps:

[0047] S100: Determine the laying position of two adjacent base plates 9, and set up a pair of base plate templates 7 at each laying position. A forming space is formed between the pair of base plate templates 7, and a first gap is formed at the joint of two adjacent base plate templates 7 on the same side.

[0048] Specifically, based on the design plan and route of the CRTSⅢ type base plate, the laying positions of two adjacent base plate sections 9 are accurately determined. The laying area is carefully cleaned and the base layer is treated to ensure that the construction surface is flat and solid. Then, at each determined laying position, a pair of base plate templates 7 are erected according to the design size and shape of the base plate 9 to form a molding space that meets the casting requirements of the base plate 9. In this embodiment, the two base plate templates 7 do not contact each other, and there is an installation space for the force transmission pad 6 between them.

[0049] Specifically, in this embodiment, the cross-sectional dimensions of the base plate template 7 are 300mm*100mm.

[0050] S200: The force transmission pad 6 is installed between two adjacent pairs of base plate templates 7 by means of a fixing component. The fixing component is used to make the force transmission pad 6 perpendicular to the base plate 9 and keep it flat. The two ends of the force transmission pad 6 extend into the corresponding first gap.

[0051] Specifically, such as Figure 2 As shown, the fixing assembly includes: a fixing plate 2 and a clamping plate. A snap-fit ​​plate 1 is provided on the top of the fixing plate 2. The clamping plate is arranged parallel to one side of the fixing plate 2, and the clamping plate and the fixing plate 2 are detachably connected by a connector. A force transmission pad 6 is provided between the fixing plate 2 and the clamping plate. In this embodiment, both the fixing plate 2 and the clamping plate are steel plates.

[0052] Specifically, a force-transmitting pad 6 with a length greater than the width of the base plate 9 to be poured is selected to ensure complete coverage of the joint between two adjacent base plates 9. In this embodiment, the dimensions of the force-transmitting pad 6 are 20mm (thickness) × 220mm (width) × 3100mm (length). Subsequently, the force-transmitting pad 6 is precisely installed between two adjacent base plate templates 7 using a fixing assembly. This fixing assembly includes components such as a fixing plate 2, a pressure plate, and a connector 5. The pressure plate is pressed evenly onto the fixing plate 2 by the connector 5. This fixing assembly ensures that the force-transmitting pad 6 maintains a perpendicular relationship with the base plate 9 throughout the installation process, and at the same time, the surface of the force-transmitting pad 6 meets the strict flatness requirements through the evenly applied pressure. Among them, the extra-long design of the force transmission pad 6 allows both ends to extend fully into the corresponding first gap, forming a complete force transmission path. This key feature effectively avoids the problem of stress concentration and cracking of the end concrete caused by insufficient length of the force transmission pad 6 in traditional construction. In this embodiment, the dimensions of the fixing plate 2 are 2mm (thickness) × 320mm (width) × 3100mm (length), and the cross-sectional dimensions of the snap-fit ​​plate 1 are 40mm × 40mm, with a length of 3200mm.

[0053] Optional, the clamping plate includes:

[0054] The clamping part 3 is disposed on the side of the force transmission pad 6 away from the fixing plate 2, and the clamping part 3 extends along a first direction; the first direction is parallel to the length direction of the force transmission pad 6.

[0055] The connecting part 4 has multiple parts, which are arranged along a first direction; and each connecting part 4 extends along a second direction and is used to connect with the connector 5; the second direction is perpendicular to the first direction.

[0056] Specifically, in this embodiment, the first direction is the horizontal direction and the second direction is the vertical direction;

[0057] Specifically, the clamping plate mainly consists of a clamping part 3 and a connecting part 4. The clamping part 3 is a long strip steel plate component. In this embodiment, the dimensions of the clamping part 3 are 20mm (thickness) × 40mm (width) × 3100mm (length). The clamping part 3 extends along the length direction (first direction) of the force transmission pad 6 and is closely attached to the side surface of the force transmission pad 6 facing away from the fixing plate 2, ensuring that a uniform clamping force is applied to the entire pad. The connecting part 4 is an ear plate structure welded to the clamping part 3. At least three are provided and arranged at equal intervals along the first direction. Each connecting part 4 extends along the second direction to form a standard connection interface. In this embodiment, the dimensions of the connecting part 4 are 20mm (thickness) × 150mm (length) × 40mm (width). Each connecting part 4 is connected to a corresponding connecting piece 5 to achieve connection with the fixed plate 2. This orthogonally arranged structure of the pressing parts 3 and connecting parts 4 ensures the continuous distribution of the pressing force along the length of the force transmission pad 6, and achieves rigid fixation of the pressing system through multi-point connection, effectively avoiding the local stress concentration and uneven pressing phenomenon commonly seen in traditional construction. The length of the pressing part 3 matches the working section length of the force transmission pad 6 to ensure coverage of the entire effective force transmission area. The number and spacing of the connecting parts 4 are determined based on the fluid pressure during concrete pouring to ensure a stable pressing effect under the maximum construction load.

[0058] Optionally, each connecting part 4 is connected to a corresponding connecting member 5, and the connecting member 5 includes:

[0059] The screw 54 is rotatably connected to the connecting part 4. The screw 54 extends along a third direction, which is perpendicular to the first direction and also perpendicular to the second direction.

[0060] The connecting nut includes a nut body 52, which is threadedly connected to the screw 54. One side of the nut body 52 has an extension 51, which extends in a third direction toward the connecting part 4. The end of the extension 51 away from the nut body 52 is bent toward the connecting part 4 to form a snap-fit ​​part 53. The snap-fit ​​part 53 is used to snap-fit ​​with the fixing plate 2.

[0061] Specifically, in this embodiment, the third direction is the horizontal direction;

[0062] Specifically, such as Figure 8As shown, the connector 5 consists of a screw 54 and a connecting nut. The screw 54 is made of high-strength alloy steel, and its axis is arranged in a third direction perpendicular to the length of the clamping part 3 and the extension direction of the connecting part 4. The connecting nut adopts a three-way split design, including a nut body 52. ​​The nut body 52 has an internal thread that matches the screw 54, and axial locking is achieved by tightening. An extension 51 is fixed on one side of the nut body 52, and the extension 51 extends towards the connecting part 4 in a third direction. The end of the extension 51 away from the nut body 52 is bent towards the connecting part 4 to form a snap-fit ​​part 53. The snap-fit ​​part 53 is used to snap-fit ​​with the fixing plate 2. This unique connector 5 structure achieves three-dimensional force balance: the extension 51 bears the axial preload, the screw body 52 provides the main fastening force through the threaded connection, and the snap-fit ​​part 53 forms an auxiliary snap-fit ​​fixation. The three work together to ensure that the clamping system does not shift or loosen during concrete pouring. In particular, the extension 51, nut body 52, and snap-fit ​​part 53 of the connecting nut are formed by an integrated forging process. At the same time, this design of the connector 5 allows construction personnel to complete the dual functions of axial fastening and radial positioning by simply rotating the screw 54, which greatly improves construction efficiency and quality stability.

[0063] Optionally, step S200 includes the following steps:

[0064] S201: Lay the force transmission pad 6 flat on one side of the fixed plate 2;

[0065] S202: Place a clamping plate on the side of the force transmission pad 6 away from the fixed plate 2, and fix the clamping plate to the fixed plate 2 through the connector 5;

[0066] S203: Install the assembled force transmission pad 6 and fixing components between two adjacent pairs of base plate templates 7, and make the snap-fit ​​plate 1 and the base plate template 7 form a limiting fixation.

[0067] Specifically, such as Figure 2 and Figure 3 As shown, firstly, the force transmission pad 6 is laid flat on the mounting surface of the fixing plate 2, ensuring that the surface of the force transmission pad 6 is completely flat and wrinkle-free; then, a clamping plate is placed on top of the force transmission pad 6, and the clamping plate is pressed and fastened to the fixing plate 2 by the connector 5, so that the force transmission pad 6 is evenly compacted; finally, the assembled force transmission pad 6 and fixing components are installed as a whole between two adjacent base plate templates 7, and the precise positioning and stable fixing are achieved by the cooperation of the snap-fit ​​plate 1 and the template; in this embodiment, the snap-fit ​​plate 1 is snapped into the top of the base plate template 7; this process effectively ensures the flatness and positional accuracy of the force transmission pad 6 during construction, creating good conditions for subsequent concrete pouring.

[0068] Optionally, after step S200 and before step S300, the following steps are also included:

[0069] S210: A sealing element 8 is installed in the first gap. The sealing element 8 is used to abut and limit the end of the force transmission pad 6.

[0070] Specifically, a first gap is formed at the joint between two adjacent base plate templates 7, and the size of this gap matches the thickness of the force transmission pad 6. In this embodiment, the first gap is 20mm. A sealing element 8 is provided in the first gap at both ends. The sealing element 8 is preferably made of 20mm thick steel plate, and its installation position corresponds to the end position of the force transmission pad 6. Through this setting, the sealing element 8 can form a tight mechanical abutment with the end of the force transmission pad 6, realizing bidirectional limiting constraint on the force transmission pad 6. This structural design ensures that the force transmission pad 6 maintains a stable planar position during concrete pouring, preventing it from shifting or twisting. On the other hand, it provides tensile force to both ends of the force transmission pad 6, realizing the flatness of the force transmission pad 6 on its entire plane and completely eliminating possible wrinkle defects.

[0071] S300: Concrete is poured simultaneously in the base plate template 7 on both sides of the force transmission pad 6;

[0072] S400: Remove the fixing components after the concrete pouring is completed;

[0073] S500: Concrete solidifies into base plate 9.

[0074] Specifically, after the force transmission pad 6 is placed, a synchronous pouring process is adopted, and concrete is poured simultaneously in the base plate templates 7 on both sides of the force transmission pad 6 to ensure that the concrete on both sides is evenly stressed and cures synchronously; after the concrete pouring is completed, the connector 5, clamping plate and fixing plate 2 in the fixing assembly are removed in sequence. The lubricating layer pre-applied on both sides of the fixing plate 2 can effectively reduce the removal resistance (in this embodiment, the lubricating layer is lubricating grease) and avoid damage to the concrete structure; finally, as Figure 4 and Figure 5 As shown, after the concrete has fully solidified, a complete base plate 9 structure is formed. At this time, the force transmission pad 6 is tightly connected with the base plates 9 on both sides, forming a continuous and stable force transmission system. The entire demolition process is carried out using special tools to ensure construction safety and structural integrity.

[0075] Optionally, the following steps may be included after step S500:

[0076] S600: Remove the base plate template 7 and cut off the portion of the force transmission pad 6 exposed on the base plate 9.

[0077] Specifically, after the concrete has completely solidified to form the structurally complete base plate 9, the base plate formwork 7 on both sides is first removed in an orderly manner. Special care must be taken to protect the newly poured concrete structure during the removal process. Then, using specialized cutting tools, the excess portion of the force-transmitting pads 6 exposed on the surface of the base plate 9 is precisely removed. The cut must be smooth and flush with the concrete surface. After this process, only the effective force-transmitting portion of the force-transmitting pads 6 embedded in the concrete at the joints of the base plate 9 remains, ensuring both the neatness and aesthetics of the structure and maintaining the integrity and functionality of the force transmission system. The entire removal process employs a vibration-free cutting technique to avoid damage to the cured concrete structure.

[0078] Working principle: This application limits the length of the force transmission pad 6 to extend into the first gap, so that the length of the force transmission pad 6 is greater than the width of the base plate 9, thereby ensuring that it completely covers the joint area and effectively solving the problem of concrete cracking at the edge of the base plate 9 caused by multiple segments of the force transmission pad 6 in traditional construction. At the same time, the fixing components are used to press on both sides to achieve initial flatness in the vertical direction. Secondly, the two ends of the force transmission pad 6 are sealed and abutted to achieve horizontal limitation, thereby ensuring the flatness of the force transmission pad 6 on the entire plane, avoiding the occurrence of wrinkles, and also avoiding the problem of cracks caused by the connection of the concrete at both ends. This improves the shear force transmission capacity and efficiency of the force transmission pad 6 and increases the service life of the force transmission pad 6.

[0079] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above are only preferred embodiments of this application. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this application, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the inventive concept and technical solution to other situations without modification, should all be considered within the scope of protection of this application.
