[0023] Regarding the problem that the double climbing cone bracket structure currently used cannot fit the tower column surface, thus affecting the stability of the climbing formwork, please refer to Figures 1 to 3 The present application provides a climbing frame anchor bracket 1, which has high safety and strong applicability. It can not only be installed on conventional straight concrete surfaces, but also is suitable for installation on curved concrete surfaces.

[0024] The climbing frame anchor bracket 1 of the present application includes a bracket body 11, a climbing cone 14 and a supporting foot 12. The bracket body 11 is used to hang and fix the guide rails and the frame of the climbing formwork system. The climbing cone 14 passes through the bracket body 11 and is used to anchor the bracket body 11 on the concrete surface. The supporting foot 12 is arranged at the bottom of the bracket body 11. The supporting foot 12 is non-fixedly connected to the bracket body 11, and the supporting foot 12 is also connected to the guide rails in the climbing formwork system. The bracket body 11 and the supporting foot 12 are both provided with adjustable bolts 13 for resisting against the concrete surface.

[0025] Specifically, the mount body 11 and the support foot 12 are both provided with threaded holes for installing the adjustable screw, and the adjustable bolt 13 includes an adjusting screw 131 and an abutment 132. The adjusting screw 131 is threadedly connected in 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 aperture of the threaded hole to limit the adjustable bolt 13 from the end of the adjusting screw 131 where the abutment 132 is set to be separated from the threaded hole. The adjustable bolt 13 adjusts the support distance between the mount body 11 and the support foot 12 and 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 mount body 11, and one adjustable bolt 13 is provided at each of the lateral ends of the support foot 12, and the three adjustable bolts 13 are not in the same straight line, so that the three-point support of the climbing frame anchor mount 1 of the present application on the concrete surface is achieved through the three adjustable bolts 13, ensuring the stability of the mount connected to any curved surface.

[0026] In addition, the mount body 11 is provided with an arc surface support 113, which includes an arc support plate provided on both sides of the mount body 11 along its vertical direction. The arc support plate fits with the concrete surface, thereby increasing the fitting area between the mount body 11 and the concrete surface to ensure close contact between the mount and the concrete surface and improve the stability of the connection between the mount and any arc surface.

[0027] Furthermore, the arc-shaped support plate is preferably made of channel steel, and is connected to the mount body 11 via the groove edge of the channel steel, so as to improve the connection stability between the arc-shaped support plate and the mount body 11 .

[0028] The mount body 11 is provided with a through hole 111 in the middle thereof 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 stress 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 thereof is threadedly connected to the cone 143. The stress bolt 144 is located outside the tower column concrete. The stress bolt 144 passes through the through hole 111 of the mount body 11 and is inserted into the other end of the cone 143 opposite to the high-strength screw 142, so as to anchor the mount body 11 to the concrete surface through the climbing cone 14.

[0029] In addition, the mounting body 11 and the support foot 12 of the present application are non-fixedly connected and can be relatively separated. The support foot 12 of the present embodiment is made of channel steel, that is, when the support foot 12 is installed, a connecting groove 121 is provided on the side of the support foot 12 close to the concrete surface. When the mounting body 11 is installed, a hook groove structure 112 that can be embedded in the connecting groove 121 is formed outward on the side of the bottom of the mounting body 11 that is away from the concrete. When the mounting body 11 and the support foot 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 foot 12, so that the two can be combined to form a whole; or, the mounting body 11 and the support foot 12 are separated from each other and respectively connected to different positions of the climbing formwork track 2, so that the inclination of the climbing formwork track 2 can be adjusted by adjusting the distance between the mounting body 11 and the support foot 12 through the adjustable bolts 13 on the mounting body 11 and the support foot 12, so as to adapt to the curved tower column structure and ensure the stability of the mounting body of the present application and any curved surface.

[0030] The climbing frame anchor bracket 1 of the present application uses only a single climbing cone 14 to anchor with the concrete structure, and cooperates with three adjustable bolts 13 to ensure the stability of the bracket and any curved surface. The single climbing cone anchoring structure used in the present application can better adapt to changes in any curved surface, avoid the problem of conventional bracket plates using multiple climbing cones, which leads to loose contact with the concrete surface, and the problem of the screw rod and the embedded parts of the climbing cone 14 not being screwed into place, which affects the stability of the climbing formwork system, ensures the safety of construction, and the single-point anchoring has a wide adjustable range and strong adaptability.

[0031] This application also relates to a climbing formwork system. Figure 3 , which includes a climbing frame anchor bracket 1, a climbing formwork track 2, a climbing formwork frame and a formwork structure, wherein the climbing formwork frame mainly provides an operating platform for construction personnel. The climbing formwork frame in this embodiment includes an upper frame and a lower frame, the upper frame is installed on the top of the lower frame, and the formwork structure is used as an outer formwork for pouring tower column concrete. It is installed on the top of the lower frame. The upper frame and the formwork structure are spaced apart. During the process of opening or closing the mold, the formwork structure moves relative to the climbing formwork frame to avoid affecting the construction of workers on the climbing formwork frame during the closing or opening of the mold, so that the workers can perform operations such as tower column steel bar binding during the closing or opening of the mold structure. The climbing frame anchor bracket is the climbing frame anchor bracket mentioned above, which includes a bracket body and a supporting foot. The bracket body and the supporting foot are provided with mounting grooves for the climbing formwork track 2 to pass through and cooperate with each other, so as to play a role in limiting and guiding 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, and a hydraulic cylinder 23 is provided between the upper reversing box 21 and the lower reversing box 22.

[0032] Specifically, when the climbing formwork track 2 climbs relative to the climbing frame anchor bracket 1, the climbing formwork frame is hung on the bracket body 11 of the climbing frame anchor bracket 1, and the climbing formwork track 2 is connected to the bracket body 11 of the climbing frame anchor bracket 1 through its upper reversing box 21 or lower reversing box 22; and when the climbing formwork frame climbs along the climbing formwork track 2, the climbing formwork track 2 is fixed to the climbing frame anchor bracket 1, and 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 with the climbing of the climbing formwork frame.

[0033] 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 for the climbing frame anchor bracket 1 to be anchored on the concrete surface of the tower column.

[0034] When the climbing formwork system of the present application is used 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 cast through the formwork structure. The surface of the semi-finished upper tower column and the lower tower column are not on the same plane. 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 supporting foot 12 of the climbing frame anchor bracket 1 can be separated from its bracket body 11. According to the change of the curvature of the tower column surface, the distance of the supporting foot 12 on the climbing formwork track 2 relative to the bracket body 11 is adjusted, and the distance between the bracket and the tower column concrete surface is adjusted by the adjustable bolts 13 on the bracket body 11 and the supporting foot 12, so that the climbing frame anchor bracket can be adapted to the installation of any curved surface, ensuring that the climbing formwork track 2 can be stably supported on the non-planar tower column concrete surface.

[0035] At the same time, the climbing formwork frame is hung on the bracket body 11 anchored on the concrete surface of the tower column, and the two are non-fixedly connected. The climbing formwork track 2 passes through the climbing frame anchor bracket 1 to be installed on the concrete surface of the tower column. The climbing formwork track 2 can move relative to the bracket body 11, and the supporting 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 supporting foot 12 of the climbing frame anchor bracket 1. The upper reversing box 21 and the lower reversing box 22 are provided with locking tongues that can be respectively connected and fixed to the climbing frame anchor bracket 1, the climbing formwork track 2 and the climbing formwork frame, so that the climbing formwork system of the present application can be realized by the reversal of the locking tongue and the telescopic operation of the hydraulic cylinder 23 to climb along the tower column.

[0036] When the climbing formwork system is climbing, the locking tongues of the upper reversing box 21 and the lower reversing box 22 are adjusted, the climbing formwork track 2 is relatively separated from the climbing formwork frame, the climbing formwork frame bears the load through the climbing frame anchoring bracket 1, and the hydraulic cylinder 23 is started to make the climbing formwork track 2 climb the wall relative to the climbing formwork frame. The supporting feet 12 on the climbing formwork track 2 approach the bracket body 11 as the climbing formwork track 2 climbs. At the same time, the top of the climbing formwork track 2 approaches the bracket body 11 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 of one stroke of the climbing formwork track 2 is completed.

[0037] Subsequently, the upper reversing box 21 on the climbing formwork track 2 is connected to the climbing formwork frame through its locking tongue, and the mounting seat body 11 arranged near the bottom of the climbing formwork track 2 is removed, and the hydraulic cylinder 23 is started to make the upper reversing box 21 and the lower reversing box 22 climb along the climbing formwork track 2, and at the same time drive the climbing formwork frame connected to the upper reversing box 21 to climb along the climbing formwork track 2, and wait for the upper reversing box 21 to move to abut against the mounting seat body 11 at the top of the climbing formwork track 2, and complete the lifting of the climbing formwork frame for one climbing formwork track 2 stroke.

[0038] The climbing formwork system of the present application completes the concrete construction of the tower column according to the climbing steps of the above-mentioned climbing formwork track 2 and the climbing formwork frame, wherein, since the climbing formwork track 2 is only fixed at a single point by the bracket body 11 during the climbing process, its bottom is supported on the concrete surface of the tower column by the adjustable bolts 13 of the supporting feet 12, so as to adjust the climbing formwork track 2 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 curves.

[0039] In summary, the climbing formwork system of the present application adopts a single-point anchored climbing frame anchor bracket 1, which can be applied to the concrete surface of the tower column with constantly changing curvature, avoiding the problem of structural stress safety risks caused by the mismatch between the bracket and the concrete. The top of the climbing formwork track 2 is connected to the bracket body 11 anchored on the concrete surface of the tower column, and the supporting foot 12 is installed under the climbing formwork track 2 and can adapt to the arc changes of the spatial curved surface of the tower column through the adjustable bolts 13 on both sides thereof. It has a wide adjustable range, strong adaptability, and high safety. The climbing formwork system can smoothly pass the curvature change point of the tower column to complete the climbing.

[0040] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
