Description

Technical Field

[0001] This utility model relates to the field of railway engineering construction, and in particular to a template for the fracture joint of a railway retaining wall and a retaining wall template. Background Technology

[0002] In the field of railway engineering construction, railway bridges, as a key component of the railway system, play a vital role. Among them, the ballast retaining wall in the bridge deck system is the main load-bearing structure, bearing the lateral pressure generated by the ballast. Typically, the ballast retaining wall adopts a long strip-shaped reinforced concrete structure, with its cross-sectional dimensions generally set at a top width of 20cm, a bottom width of 25cm, and a height ranging from 45cm to 80cm.

[0003] Given that railway bridges need to withstand high-frequency vibrations and cope with deformation caused by temperature differences over long periods, a 1cm wide joint is installed every 2m along the length of the retaining wall to meet this practical requirement. This joint is a continuous, open structure. The construction process of the joint has a direct and crucial impact on the construction quality and appearance of the retaining wall joint.

[0004] In existing technologies, for the construction of ballast retaining wall joints, a single piece of bamboo plywood or rigid foam board is usually used as a temporary formwork at the joint. However, the removal of this single formwork after the concrete is poured is quite difficult. Not only is it easy to leave residue during removal, but it may also cause chipped edges and corners in the ballast retaining wall at the joint, which seriously affects the appearance quality of the joint and results in a poor appearance. Utility Model Content

[0005] The purpose of this utility model is to overcome the problem that the template for the fracture position of the ballast retaining wall in the prior art will result in poor appearance of the fracture, and to provide a template for the fracture of the railway ballast retaining wall and a ballast retaining wall template.

[0006] In a first aspect, this utility model provides a template for the joint of a railway retaining wall, comprising:

[0007] Two template components are arranged centrally symmetrically and connected to each other; each template component includes a first unit block and a second unit block; the first unit block includes a first plane and a first inclined surface; the second unit block includes a second plane and a second inclined surface.

[0008] The first inclined surface and the second inclined surface are connected to each other, and the first plane and the second plane are respectively used to form the end face of the corresponding retaining wall.

[0009] The retaining wall end face corresponding to the first plane refers to the end face of the first plane that contacts the retaining wall after the two formwork components are installed to the joint position. The retaining wall end face corresponding to the second plane refers to the end face of the second plane that contacts the retaining wall after the two formwork components are installed to the joint position.

[0010] The overall length formed by the butt joint of the two template components should be greater than the width of the retaining wall. The thickness of the template component is determined based on the width of the joint in the retaining wall.

[0011] This utility model provides a template for the joint of a railway ballast retaining wall. The template is formed by two template components joined together in a centrally symmetrical manner, used to shape the joint of the ballast retaining wall. A first unit block and a second unit block within the same template component are connected by a first inclined surface and a second inclined surface. After the ballast retaining wall has been poured and shaped, the first unit block can be slid outwards from the side corresponding to the joint, thus disassembling the first unit block. After the first unit block is disassembled, a corresponding space is created at the joint location, facilitating the disassembly of the second unit block. Finally, the demolding operation at the joint location of the ballast retaining wall can be successfully completed.

[0012] Traditional templates for fracture locations are single, indivisible pieces placed directly at the fracture point. This application, however, employs two template components, each comprising a first unit block and a second unit block. Compared to traditional fracture location templates, the template of this application is easier and more convenient to demold, eliminating the need for force. This prevents residue or chipped edges at the fracture location, improving its appearance quality.

[0013] The template components can be made of materials such as steel, aluminum alloy, rigid plastic, glass fiber reinforced plastic, or ceramic materials.

[0014] Preferably, the cross-section of the first unit block is a right triangle, which includes a longer right-angled side, a shorter right-angled side, and a hypotenuse. The side containing the longer right-angled side serves as the first plane, and the side containing the hypotenuse of the right triangle serves as the first inclined plane. Compared to other cross-sectional shapes, the right triangle shape of the first unit block in this design makes manufacturing more convenient.

[0015] Preferably, the cross-section of the second unit block is a right trapezoid, the side containing the lower base of the right trapezoid is the second plane, and the side containing the hypotenuse of the right trapezoid is the second inclined plane.

[0016] Preferably, the height of the right trapezoid exceeds half the overall thickness of the template component. The overall thickness of the template component is consistent with the width of the fracture. The side containing the right-angled leg of the right trapezoid serves as the mating surface of the second unit block. This design allows the mating surfaces of the two second unit blocks to partially overlap, thus facilitating their connection.

[0017] Preferably, the first inclined surface is provided with a screw hole, and the second inclined surface is provided with a first through hole, through which a screw passes. The connection between the first unit block and the second unit block is achieved by screwing the screw into the screw hole. This design ensures a stable connection between the first unit block and the second unit block, preventing relative slippage during concrete pouring or vibration.

[0018] Preferably, the first unit block is provided with a first pull ring, and the second unit block is provided with a second pull ring. During disassembly, the first pull ring and the second pull ring can provide force support points for the corresponding first unit block and second unit block, respectively, making the disassembly process easier and more convenient.

[0019] The first pull ring and the second pull ring can be made of stainless steel, aluminum alloy, steel bars, steel wire or engineering plastics, etc.

[0020] Preferably, both the first pull ring and the second pull ring are made of steel bars or steel wires.

[0021] Preferably, the angle between the first plane and the first inclined plane, and the angle between the second plane and the second inclined plane, are both 5°-30°.

[0022] Preferably, the first and second inclined surfaces are coated with organic oil, and the first and second flat surfaces are coated with a release agent. The organic oil enhances the lubrication between the first and second unit blocks, thereby reducing friction between them. This allows for easier separation of the first and second unit blocks during subsequent disassembly. The release agent facilitates the separation of the first and second unit blocks from the formed concrete during disassembly.

[0023] In a second aspect, this utility model provides a railway retaining wall template, including side templates and a template for a railway retaining wall joint, wherein two template components of the template for the railway retaining wall joint are respectively connected to the corresponding side templates by bolts.

[0024] On either side of the fracture are two adjacent sections of retaining wall. On each side of the two retaining wall sections, a side formwork is installed. Two formwork components are connected to their respective side formworks via bolts; specifically, these two formwork components are connected to the side formworks of the two adjacent retaining wall sections located on the same side.

[0025] This utility model provides a template for a railway ballast retaining wall, wherein the side template and the template for the joint of the railway ballast retaining wall together enclose the concrete pouring area of ​​the ballast retaining wall. By using the template of this application, the ballast retaining wall is easier and more convenient to dismantle, which helps to improve the appearance quality of the joint.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. This utility model provides a template for the joint of a railway retaining wall. By employing two template components, each comprising a first unit block and a second unit block, the template of this application allows for easier and more convenient demolding without the need for forceful methods. This prevents residue or chipped edges at the joint location, thus improving the appearance quality of the joint.

[0028] 2. This utility model provides a template for railway retaining walls. By adopting the template of this application, the retaining walls are easier and more convenient to dismantle, which helps to improve the appearance quality of the joints. Attached Figure Description

[0062] Example 2

[0063] A type of railway retaining wall formwork, such as Figure 5 As shown, the template includes a side template 3 and a template for a railway ballast retaining wall joint as described in Embodiment 1. The two template components 1 of the template for the railway ballast retaining wall joint are respectively connected to the corresponding side template 3 via bolts 6.

[0064] Specifically, a second through hole 115 is provided on the first inclined surface 112, and a third through hole 125 is provided on the second inclined surface 122. Bolts 6 are used to pass through the second through hole 115, the third through hole 125, and the corresponding side template 3, thereby connecting the template component 1 with the corresponding side template 3.

[0066] Example 3

[0067] This embodiment describes the method of using a template for a railway retaining wall fracture as described in Embodiment 1, including the following steps:

[0068] Installation Phase: Apply machine oil evenly to the first inclined surface 112 of the first unit block 11 and the second inclined surface 122 of the second unit block 12. Connect the two first unit blocks 11 to their corresponding second unit blocks 12 using screws 5 to complete the assembly of the template component 1. Arrange the two assembled template components 1 in a centrally symmetrical manner, such as... Figure 5 As shown, it is placed at the joint of the retaining wall. The first unit block 11 and the second unit block 12 are connected and fixed to the side formwork 3 using bolts 6 to ensure the stability of the overall structure. A release agent is evenly applied to the first plane 111 and the second plane 121.

[0069] Pouring stage: Concrete pouring operation is carried out in concrete pouring area 4. During the pouring process, vibration equipment is used to vibrate the concrete to ensure that the concrete is dense, uniform and free of defects such as voids.

[0070] Dismantling Stage: When the concrete strength reaches the demolding condition (e.g., concrete strength reaches 2.5 MPa), dismantling work begins. First, remove bolts 6 and screws 5 to disconnect the first unit block 11 and the second unit block 12 from the side formwork 3, as well as the connection between the first unit block 11 and the second unit block 12. Pull the first pull rings 113 corresponding to the two first unit blocks 11 from the left and right sides of the retaining wall to pull the two first unit blocks 11 horizontally out of the joint. Continue to pull the second pull rings 123 corresponding to the two second unit blocks 12 from the top of the retaining wall to pull the two second unit blocks 12 vertically upward from the joint, thus completing the joint construction.

[0071] The device involved in this application has the characteristic of being able to be reused multiple times after being processed once. This advantage is significant in two aspects: firstly, it effectively saves processing time and material costs, thereby reducing the overall construction cost; secondly, compared with bamboo plywood or rigid foam board commonly used in traditional construction, traditional materials require additional processing before each construction, while the device of this application does not require this step, thus greatly improving construction efficiency.

[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
