Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a settlement joint plate fixing device for continuous casting of capping. Background Technology

[0002] With societal development and the growing acceptance of quality concepts, the demands for engineering quality are increasing, often necessitating higher costs. For existing vertical revetment restoration projects like the Beijing-Hangzhou Grand Canal, achieving rapid, low-cost, and high-quality restoration has become a significant engineering challenge. Quality, cost, and efficiency are inherently contradictory. To reduce costs, construction companies typically opt for partial restoration, and revetment capping restoration is one of the most common types of construction projects with the highest requirements for aesthetic quality.

[0003] For wall coping repair, the appearance quality of the concrete is relatively controllable. However, to ensure construction efficiency, the coping is usually poured continuously. The installation of settlement joints between adjacent sections becomes a quality control challenge. Previously, concrete structures were typically constructed intermittently, with settlement joint slabs supported and fixed by end formwork. If continuous pouring is adopted, the settlement joint slabs lack fixed support, leading to twisting and deformation during concrete pouring, making it difficult to meet construction quality standards. To solve this problem, steel reinforcement or angle steel supports were installed on both sides of the settlement joint slabs to prevent movement. This process generally ensured the stability of the slabs during concrete pouring. However, within the concrete reinforcement protective layer, to ensure the quality of the reinforcement protective layer, the slabs, without fixed support from the outside of the reinforcement mesh to the concrete surface, experienced slight twisting and deformation, affecting the construction quality. There is currently no effective solution to this problem under continuous coping pouring conditions. Utility Model Content

[0026] Example 1:

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution: a settlement joint plate fixing device for continuous casting of a capping plate, including a capping plate 1, which is fixed on the top of the concrete structure to form a vertical casting gap. In use, the capping plate 1 needs to be fixedly connected to the waler or external support frame. A first fixing component for restricting the settlement joint plate in the vertical direction is provided on the inner side wall of the capping plate 1, and a second fixing component for restricting the settlement joint plate in the horizontal direction is provided at the upper end of the capping plate 1.

[0028] The first fixing component includes a fixing groove 2 that is detachably connected to the inner wall of the capping template 1. The width of the fixing groove 2 is customized with reference to the width of the settlement joint plate. The cross-section of the fixing groove 2 is U-shaped, and the width of the bottom of the fixing groove 2 is greater than the width of its opening, so that the fixing groove 2 can be easily removed from the settlement joint opening when it is removed.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the first fixing components are provided on both the left and right sides of the settlement joint plate, that is, two sets of fixing grooves 2 are provided and symmetrically arranged. The left and right sides of the settlement joint plate are inserted into the fixing grooves 2. The symmetrically arranged fixing grooves 2 clamp the settlement joint plate and fix the fixing grooves 2 on the capping template 1. The vertical direction of the fixing grooves 2 is parallel to the vertical direction of the capping template 1 and both are vertically downward, thereby ensuring that the settlement joint plate is perpendicular to the capping template 1.

[0030] The two ends of the fixing groove 2 do not extend to the edge of the capping template 1, which provides sufficient space for the settlement joint plate to move and makes it easy to remove it later. In addition, the fixing groove 2 and the capping template 1 are connected in a detachable manner, which makes it easy to remove the fixing groove 2 from the capping template 1 after use and to reuse it.

[0031] Multiple fixing bolts 21 are installed on the top platen 1. The bottom of the fixing groove 2 is provided with a first threaded hole that matches the fixing bolts 21. By passing the fixing bolts 21 through the top platen 1 and screwing them into the bottom of the fixing groove 2, the fixing groove 2 can be detachably installed on the inner wall of the top platen 1. By removing the fixing bolts 21 in sequence, the connection between the fixing groove 2 and the top platen 1 can be disconnected.

[0032] The second fixing component includes symmetrically arranged clamping plates 3 and clamping bolts 31 (i.e., bolts extending laterally in the figure) passing through the clamping plates 3. The upper surface of the capping template 1 has a second threaded hole matching the clamping bolts 31. Preferably, the clamping plates 3 can be designed as L-shaped steel plates, and a rust inhibitor can be applied to the outer wall. This not only provides excellent stability but also prevents steel reinforcement corrosion from affecting structural stability. Both ends of the clamping plates 3 are fixedly connected to the capping template 1. The clamping plates 3 are perpendicular to the capping template 1, aligning the lateral direction of the settlement joint plate with the lateral direction of the clamping plates 3. This further ensures that the settlement joint plate is perpendicular to the capping template 1, thereby restricting the position of the settlement joint plate and ensuring its verticality and straightness, thus guaranteeing construction quality and efficiency.

[0033] Working principle: First, the fixing groove 2 is fixedly connected to the capping template 1. The fixing bolts 21 are passed through the capping template 1 and screwed into the bottom of the fixing groove 2. The workers then fix the capping template 1 to the waler or external support frame. Next, the settlement joint plate is inserted into the fixing groove 2, so that the two sides of the settlement joint plate abut against the bottom wall of the fixing groove 2. Then, two clamping plates 3 are placed on the front and rear sides of the settlement joint plate respectively. Next, the tightening bolts 31 are passed through the clamping plates 3 and tightened onto the upper surface of the capping template 1, thereby fixing the settlement joint plate between the two clamping plates 3. Finally, steel bars or angle steel supports are used to connect with the steel mesh for overall fixation to prevent overall displacement. When dismantling is required, the workers first remove the fixing bolts 21 in sequence to disconnect the fixing groove 2 from the capping template 1. The capping template 1 is removed first, and the fixing groove 2 is removed after the concrete strength is high to ensure the integrity of the settlement joint.

[0034] Example 2:

[0035] Please see Figure 5It should be noted that, in addition to using the fixing bolt 21, other common structures used for connection and fixation (such as hinges, buckles, screws, etc.) can also be used to achieve a detachable connection between the fixing groove 2 and the top platen 1. A wedge block 22 is fixedly connected to the bottom wall of the fixing groove 2. An installation groove 23 matching the wedge block 22 is opened on the top platen 1. The upper end of the installation groove 23 is closed, and a limiting bolt 24 passes through the bottom of the lower end of the installation groove 23. A limiting hole 25 matching the limiting bolt 24 is opened on the wedge block 22. The limiting hole 25 is an internally threaded hole matching the limiting bolt 24. The cross-section of the wedge block 22 is an inverted trapezoid, triangle, or dovetail shape. Other parts remain unchanged, and refer to Embodiment 1.

[0036] The specific operation is as follows: First, fix the fixing groove 2 to the capping template 1, insert the wedge block 22 into the corresponding installation groove 23, then pass the limiting bolt 24 through the bottom wall of the installation groove 23 and screw it into the limiting hole 25. The workers fix the capping template 1 to the waler or external support frame. Next, insert the settlement joint plate into the fixing groove 2 so that the two sides of the settlement joint plate abut against the bottom wall of the fixing groove 2. Then, place the two clamping plates 3 on the front and back sides of the settlement joint plate respectively. Then, pass the clamping bolt 31 through the clamping plate 3 and tighten the clamping bolt 31 on the upper surface of the capping template 1, thereby fixing the settlement joint plate between the two clamping plates 3. Finally, use steel reinforcement or angle steel support to connect with the steel mesh for overall fixation to prevent overall displacement. When dismantling is required, the workers first remove the limit bolts 24 in sequence, and then the fixing groove 2 can be pulled out from the top formwork 1. The top formwork 1 is removed first, and the fixing groove 2 is removed when the concrete strength is high, so as to ensure the integrity of the settlement joint.
