Description

Technical Field

[0001] This application relates to the field of tower construction, and more particularly to a climbing formwork system. Background Technology

[0002] With the development of bridges, various irregularly shaped towers have also increased. The towers in this project are spatial curved irregular-shaped tower structures. Climbing formwork is required for the construction of these towers. However, ensuring the climbing formwork fits snugly against the curved surface during its upward ascent is a problem that needs to be solved. Conventional climbing formwork systems typically use double climbing cones on both sides for anchoring, which is only suitable for flat towers. When used on curved towers, the distance between the climbing cones and the concrete is difficult to control, resulting in gaps. If the surface is constantly changing, varying arc lengths can prevent the climbing cones from being anchored securely. Furthermore, the double climbing cones offer limited adjustment space, and for curved structures, gaps may appear between the mounting plate and the concrete, posing a structural risk. Summary of the Invention

[0003] The purpose of this application is to provide a climbing formwork system that can adapt to the concrete construction of curved tower columns and has high construction safety.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A climbing formwork system includes a climbing frame anchoring bracket, a climbing formwork track, and a climbing formwork frame body. The climbing frame anchoring bracket is anchored to a concrete surface. The climbing frame anchoring bracket includes a bracket body, a climbing cone, and supporting feet. The climbing cone passes through the bracket body to anchor the bracket body to the tower column surface. The supporting feet are located at the bottom of the bracket body. The climbing formwork track is located between the climbing frame anchoring bracket and the climbing formwork frame body. The climbing formwork frame body climbs along the length of the climbing formwork track.

[0006] Further configuration: The climbing formwork track is equipped with an upper reversing box, a lower reversing box, and a hydraulic cylinder, with both ends of the hydraulic cylinder connected to the upper reversing box and the lower reversing box, respectively.

[0007] Further configuration: When the climbing formwork track rises relative to the climbing frame anchor bracket, the climbing formwork frame body is hung on the bracket body of the climbing frame anchor bracket, and the climbing formwork track is connected to the climbing frame anchor bracket through an upper reversing box or a lower reversing box.

[0008] When the climbing formwork frame ascends along the climbing formwork track, the climbing formwork track is fixed to the climbing formwork anchorage, and the climbing formwork frame is connected to the upper or lower reversing box of the climbing formwork track.

[0009] Further configuration: The upper reversing box and the lower reversing box are respectively provided with locking tongues that are connected and fixed to the climbing frame anchor bracket, the climbing formwork track and the climbing formwork body.

[0010] Further configuration: The bracket body and the support foot are both equipped with adjustable bolts that abut against the concrete surface. One adjustable bolt is provided on the top of the bracket body, and one adjustable bolt is provided at each of the two lateral ends of the support foot.

[0011] Further configuration: The adjustable bolt includes an adjusting screw and an abutment. The adjusting screw is threadedly connected to a threaded hole in the bracket body and the support base. The abutment is located at the end of the adjusting screw to abut against the concrete surface.

[0012] Further configuration: The climbing cone includes an embedded plate, a high-strength screw rod, a cone body, and a load-bearing bolt. The embedded plate, high-strength screw rod, and cone body are all pre-embedded in concrete. One end of the high-strength screw rod is connected to the embedded plate, and the other end is threaded into the cone body. The load-bearing bolt passes through the through hole of the mounting body and is inserted into the other end of the cone body that is connected to the high-strength screw rod.

[0013] Further configuration: The climbing cone is pre-embedded in the concrete with multiple sets of embedded plates, high-strength screws and cones arranged vertically along the concrete.

[0014] Further configuration: the hanging body and the support foot are not fixedly connected, a connecting groove is provided on one side of the support foot, and a hook groove structure that can be embedded in the connecting groove is formed at the bottom of the hanging body.

[0015] Further configuration: The mounting body is provided with an arc-shaped support, which includes arc-shaped support plates located on both sides of the mounting body along its vertical direction.

[0016] Compared with existing technologies, the solution in this application has the following advantages:

[0017] The climbing formwork system of this application adopts a climbing frame anchoring bracket anchored by a single climbing cone, reducing the gap between the bracket and the concrete surface caused by the use of multiple climbing cones. This allows it to adapt to the curvature changes of the concrete surface of the tower column, ensuring the safety of the construction process. Furthermore, the single climbing cone anchoring has a wide adjustable range and strong adaptability. In addition, adjustable bolts are set on the climbing frame anchoring bracket to enhance the support stability of the climbing frame anchoring bracket, climbing formwork track and concrete surface. Moreover, the bracket body and support foot of the climbing frame anchoring bracket are not fixedly connected and can be separated. The bracket body and support foot can be combined to form a whole, or they can be separated and connected to different positions on the climbing formwork track. Thus, the inclination of the climbing formwork track can be adjusted by adjusting the distance between the bracket body and support foot using the adjustable bolts on the bracket body and support foot to adapt to curved tower column structures and ensure the connection stability of the bracket with any arc surface.

[0030] To address the issue that the current double-climbing cone hanger structure cannot conform to the curved surface of the tower column, thus affecting the stability of the climbing formwork, please refer to [link to relevant documentation]. Figures 1 to 3 This application provides a climbing frame anchor bracket 1, which has high safety and strong applicability. It can be installed not only on conventional straight concrete surfaces, but also on curved concrete surfaces.

[0031] The climbing formwork anchor 1 of this application includes a gantry body 11, a climbing cone 14, and a support foot 12. The gantry body 11 is used to suspend and fix the guide rail and frame of the climbing formwork system. The climbing cone 14 passes through the gantry body 11 and is used to anchor the gantry body 11 to the concrete surface. The support foot 12 is located at the bottom of the gantry body 11. The support foot 12 is not fixedly connected to the gantry body 11, and the support foot 12 is also connected to the guide rail in the climbing formwork system. Both the gantry body 11 and the support foot 12 are provided with adjustable bolts 13 for abutting against the concrete surface.

[0032] Specifically, both the mounting body 11 and the support foot 12 are provided with threaded holes for installing adjustable bolts. The adjustable bolt 13 includes an adjusting screw 131 and an abutment 132. The adjusting screw 131 is threaded into the threaded hole, and the abutment 132 is used to abut against the concrete surface of the tower column. The maximum outer diameter of the abutment 132 is larger than the diameter of the threaded hole to prevent the adjustable bolt 13 from disengaging from the end of the adjusting screw 131 where the abutment 132 is located. The adjustable bolt 13 adjusts the support distance from the mounting body 11 and the support foot 12 to the concrete surface by rotating its adjusting screw 131. In this embodiment, at least three adjustable bolts 13 are provided. Specifically, one adjustable bolt 13 is provided at the top of the mounting body 11, and one adjustable bolt 13 is provided at each of the two lateral ends of the support foot 12. These three adjustable bolts 13 are not on the same straight line, thereby achieving three-point support of the climbing frame anchoring mounting 1 to the concrete surface through the three adjustable bolts 13, ensuring the stability of the connection between the mounting and any arc surface.

[0033] In addition, the bracket body 11 is provided with an arc surface support 113. The arc surface support 113 includes arc-shaped support plates located on both sides of the bracket body 11 along its vertical direction. The arc-shaped support plates are in contact with the concrete surface, which increases the contact area between the bracket body 11 and the concrete surface, so as to ensure the close contact between the bracket and the concrete surface and improve the stability of the connection between the bracket and any arc surface.

[0034] Furthermore, the arc-shaped support plate is preferably made of channel steel, and is connected to the hanger body 11 through the groove edge of the channel steel to improve the connection stability between the arc-shaped support plate and the hanger body 11.

[0035] The mounting body 11 has a through hole 111 in its middle for the climbing cone 14 to pass through. The climbing cone 14 includes an embedded plate 141, a high-strength screw 142, a cone 143, and a load-bearing bolt 144. The embedded plate 141, the high-strength screw 142, and the cone 143 are all pre-embedded in the tower column concrete. One end of the high-strength screw 142 is fixed to the embedded plate 141, and the other end is threaded into the cone 143. The load-bearing bolt 144 is located outside the tower column concrete. The load-bearing bolt 144 passes through the through hole 111 of the mounting body 11 and is inserted into the other end of the cone 143 relative to the end connected to the high-strength screw 142, so as to anchor the mounting body 11 to the concrete surface through the climbing cone 14.

[0036] Furthermore, the mounting body 11 and the support leg 12 in this application are not fixedly connected and can be relatively separated. In this embodiment, the support leg 12 is made of channel steel. That is, when the support leg 12 is installed, a connecting groove 121 is provided on the side of the support leg 12 closest to the concrete surface. When the mounting body 11 is installed, a hook groove structure 112 is formed on the side of its bottom facing away from the concrete, which can be embedded in the connecting groove 121. When the mounting body 11 and the support leg 12 are close to each other, the hook groove structure 112 at the bottom of the mounting body 11 can be embedded in the connecting groove 121 of the support leg 12, so that the two can be combined to form a whole. Alternatively, the mounting body 11 and the support leg 12 can be separated from each other and connected to different positions on the climbing formwork track 2. The inclination of the climbing formwork track 2 can be adjusted by adjusting the distance between the mounting body 11 and the support leg 12 using the adjustable bolts 13 on the mounting body 11 and the support leg 12, so as to adapt to the curved tower column structure and ensure the stability of the mounting of this application with any arc surface.

[0037] The climbing formwork anchorage 1 of this application uses only a single climbing cone 14 to anchor to the concrete structure, and is equipped with three adjustable bolts 13 to ensure the stability of the anchorage with any curved surface. The single climbing cone anchorage structure adopted in this application can better adapt to arbitrary curved surface changes, avoiding the problems caused by conventional anchorage plates using multiple climbing cones, such as poor contact with the concrete surface and inadequate tightening between the bolt and the pre-embedded part of the climbing cone 14, which affect the stability of the climbing formwork system. This ensures the safety of construction, and the single-point anchorage has a wide adjustable range and strong adaptability.

[0038] This application also relates to a climbing model system; please refer to... Figure 3 It includes a climbing formwork anchor 1, a climbing formwork track 2, a climbing formwork frame body, and a template structure. The climbing formwork frame body mainly provides an operating platform for construction workers. In this embodiment, the climbing formwork frame body includes an upper frame body and a lower frame body. The upper frame body is installed on top of the lower frame body. The template structure serves as the outer formwork for the concrete pouring of the tower column and is installed on top of the lower frame body. The upper frame body and the template structure are spaced apart. During the opening or closing of the formwork, the template structure moves relative to the climbing formwork frame body to avoid affecting the workers on the climbing formwork frame body during the opening or closing of the formwork. This allows workers to perform operations such as tying the tower column reinforcement during the opening or closing of the formwork. The climbing formwork anchor bracket is the climbing formwork anchor bracket mentioned above. It includes a bracket body and support feet. Both the bracket body and support feet are provided with mounting grooves for the climbing formwork track 2 to pass through and cooperate with each other, so as to limit and guide the climbing of the climbing formwork track 2. The climbing formwork track 2 is provided with an upper reversing box 21 and a lower reversing box 22. A hydraulic cylinder 23 is provided between the upper reversing box 21 and the lower reversing box 22.

[0039] Specifically, when the climbing formwork track 2 climbs relative to the climbing frame anchoring bracket 1, the climbing formwork frame is hung on the bracket body 11 of the climbing frame anchoring bracket 1, and the climbing formwork track 2 is connected to the bracket body 11 of the climbing frame anchoring bracket 1 through its upper reversing box 21 or lower reversing box 22; while when the climbing formwork frame climbs along the climbing formwork track 2, the climbing formwork track 2 is fixed to the climbing frame anchoring bracket 1, the climbing formwork frame is connected to the upper reversing box 21 or lower reversing box 22 of the climbing formwork track 2, and the formwork structure moves together with the climbing formwork frame as it climbs.

[0040] When the concrete of the tower column is poured through the formwork structure, multiple sets of embedded plates 141, high-strength screws 142 and cones 143 as climbing cone embedded parts can be pre-embedded along the vertical direction of the tower column so that the climbing frame anchoring bracket 1 can be anchored to the concrete surface of the tower column.

[0041] When using the climbing formwork system of this application for tower column concrete construction, the climbing formwork system is hung on the concrete surface of the lower tower column segment, and the upper tower column segment is poured through the formwork structure. The surfaces of the upper tower column and the lower tower column are not on the same plane when the half-finished upper tower column is poured. First, the climbing frame anchor bracket 1 is anchored on the concrete surface of the upper tower column. The bracket body 11 of the climbing frame anchor bracket 1 is fixed to the concrete surface by a single climbing cone 14. The support foot 12 of the climbing frame anchor bracket 1 can be separated from its bracket body 11. According to the curvature change of the tower column surface, the distance of the support foot 12 on the climbing formwork track 2 relative to the bracket body 11 is adjusted. The distance between the bracket and the concrete surface of the tower column is adjusted by the adjustable bolts 13 on the bracket body 11 and the support foot 12, so that the climbing frame anchor bracket can be adapted to the installation of any arc surface, and the climbing formwork track 2 can be stably supported on the non-planar concrete surface of the tower column.

[0042] Meanwhile, the climbing formwork frame is hung on the bracket body 11 anchored to the concrete surface of the tower column. The two are not fixedly connected. The climbing formwork track 2 passes through the climbing formwork anchor bracket 1 and is installed on the concrete surface of the tower column. The climbing formwork track 2 can move relative to the bracket body 11. The support foot 12 is fixed on the climbing formwork track 2. The upper reversing box 21, the lower reversing box 22 and the hydraulic cylinder 23 on the climbing formwork track 2 are located between the bracket body 11 and the support foot 12 of the climbing formwork anchor bracket 1. The upper reversing box 21 and the lower reversing box 22 are provided with locking tongues that can be connected and fixed to the climbing formwork anchor bracket 1, the climbing formwork track 2 and the climbing formwork frame respectively. Thus, the climbing formwork system of this application can climb along the tower column by the reversing of the locking tongues and the extension and retraction of the hydraulic cylinder 23.

[0043] When the climbing formwork system is climbing, the locking tongues of the upper reversing box 21 and the lower reversing box 22 are adjusted, and the climbing formwork track 2 is separated from the climbing formwork frame. The climbing formwork frame is supported by the climbing frame anchor bracket 1. The hydraulic cylinder 23 is activated to make the climbing formwork track 2 climb relative to the climbing formwork frame. The support foot 12 on the climbing formwork track 2 moves closer to the bracket body 11 as the climbing formwork track 2 climbs. At the same time, the top of the climbing formwork track 2 moves closer to the bracket body 11 that has been installed on the concrete surface of the upper tower column. After the top of the climbing formwork track 2 is connected to the bracket body 11 located on the concrete surface of the upper tower column, the climbing formwork track 2 completes one stroke of climbing.

[0044] Subsequently, the upper reversing box 21 on the climbing formwork track 2 is connected to the climbing formwork frame body through its locking tongue, and the hanging seat body 11 near the bottom of the climbing formwork track 2 is removed. The hydraulic cylinder 23 is activated to make the upper reversing box 21 and the lower reversing box 22 climb along the climbing formwork track 2, while driving the climbing formwork frame body connected to the upper reversing box 21 to climb along the climbing formwork track 2. When the upper reversing box 21 moves to abut against the hanging seat body 11 at the top of the climbing formwork track 2, the lifting of the climbing formwork frame body for one climbing formwork track 2 stroke is completed.

[0045] The climbing formwork system of this application completes the concrete construction of the tower column according to the climbing formwork track 2 and climbing formwork frame as described above. In this case, the climbing formwork track 2 is only fixed at a single point by the hanging body 11 during the climbing process, and its bottom is supported on the concrete surface of the tower column by the adjustable bolts 13 of the support foot 12. This allows the climbing formwork track 2 to be adjusted to adapt to the curvature changes of the concrete surface of the tower column, and can meet the climbing requirements of concrete surfaces with different curvatures.

[0046] In summary, the climbing formwork system of this application adopts a single-point anchoring climbing frame anchor bracket 1, which can be applied to the concrete surface of the tower column with constantly changing curvature. This avoids the problem of structural stress safety risks caused by the bracket not fitting the concrete surface. The top of the climbing formwork track 2 is connected to the bracket body 11 anchored to the concrete surface of the tower column. The support feet 12 are installed below the climbing formwork track 2 and can adapt to the arc changes of the spatial curvature of the tower column through the adjustable bolts 13 on both sides. It has a wide adjustment range, strong adaptability, and high safety. The climbing formwork system can smoothly pass through the points of curvature change of the tower column to complete the climb.

[0047] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
