Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a multi-stage assembly device for ultra-high piers with large cross-section heavy hydraulic climbing formwork. Background Technology

[0002] Piers are common load-bearing structures in civil engineering used to support the superstructure. Piers with a height between 15 and 25 meters are called general piers, those between 25 and 35 meters are called high piers, and those over 35 meters are called super high piers.

[0003] Due to the large size of the piers, the current practice is to pour concrete layer by layer using climbing formwork. After each layer of concrete is poured, the climbing formwork is raised along the height of the pier surface, and then the concrete pouring continues for the next layer until the concrete pouring of the pier is completed.

[0004] Existing climbing formwork typically includes a frame structure, a climbing mechanism, and a formwork mechanism. The climbing mechanism is installed on the pier surface, the frame structure is mounted on the climbing mechanism, and the formwork mechanism is mounted on the frame structure. The climbing mechanism moves the frame structure along the height of the pier, while the formwork mechanism provides shaping support for the concrete pouring of the next layer of pier. After the current layer of pier concrete is poured, the climbing mechanism again moves the frame structure along the height of the pier to pour concrete for the next layer, thus achieving continuous pouring.

[0005] Existing frame structures generally include a placement platform, which typically consists of a back brace and a platform panel. To improve the stability of the platform panel, it is usually made of a single piece. When installing the placement platform, the back brace is first placed on the ground, and then the platform panel is placed on the back brace. The back brace and platform panel are then fixedly connected. The back brace reinforces the structural strength of the platform panel, thus completing the installation of the placement platform.

[0006] Regarding the aforementioned technologies, the inventors believe that when installing and placing the platform, if the cross-section of the pier column is large, the platform plate is generally large in size. When assembling and placing the platform, the larger platform plate requires a larger assembly space. When the pier column is located in a small, steep mountainous area, an additional assembly site needs to be excavated for assembly. Consequently, there is a drawback that it is inconvenient to install climbing formwork. Summary of the Invention

[0007] To improve the installation efficiency of climbing formwork, this application provides a multi-stage assembly device for ultra-high pier large-section heavy hydraulic climbing formwork.

[0008] The technical solution of the multi-stage assembly device for ultra-high piers with large cross-section heavy hydraulic climbing formwork provided in this application is as follows:

[0009] A multi-stage assembly device for heavy-duty hydraulic climbing formwork for ultra-high piers with large cross-sections includes a frame mechanism, a climbing mechanism, and a formwork mechanism. The frame mechanism includes several groups of working platforms distributed along the height direction of the pier column. The working platforms in the same group are distributed circumferentially along the axial direction of the pier column. Each working platform includes a horizontal plate and a vertical plate placed on top of the horizontal plate. Two adjacent horizontal plates in the same group are detachably connected by a connecting component, and two adjacent groups of horizontal plates are detachably connected by a fixing component. A working area is formed between the pier column sidewall, the horizontal plate, and the vertical plate.

[0010] By adopting the above technical solution, when climbing formwork needs to be installed, after the climbing mechanism is installed on the side wall of the pier, individual working platforms are lifted sequentially, allowing each platform to be installed on the side wall of the pier via the climbing mechanism. Working platforms in the same group are distributed circumferentially along the pier axis, and adjacent working platforms in the same group are detachably connected via connecting components. After the installation of the working platforms in the same group is completed, other groups of working platforms are installed on the side wall of the pier in a bottom-to-top sequence, and adjacent groups of working platforms are detachably connected via fixing components. After the frame structure is installed, the formwork mechanism is installed on top of the frame structure. When the pier cross-section is large, the frame structure is broken down into multiple working platforms, and the assembly of the frame structure is reduced by installing them one by one, improving the ease of assembly and reducing the space occupied for assembling the frame structure, thereby improving the convenience of installing the climbing formwork.

[0011] Optionally, a plurality of positioning blocks are provided on one side of the horizontal plate, and the plurality of positioning blocks are spaced apart along the length direction of the horizontal plate. A plurality of positioning grooves are provided on the other side of the horizontal plate, and the plurality of positioning grooves are spaced apart along the length direction of the horizontal plate. The plurality of positioning blocks and the plurality of positioning grooves correspond one-to-one, and each positioning block and the corresponding positioning groove are inserted into each other.

[0012] By adopting the above technical solution, when connecting two adjacent horizontal plates in the same group, the two horizontal plates are brought close to each other, and the positioning block is inserted into the corresponding positioning groove. The inner wall of the positioning groove is positioned by the positioning block to improve the positional accuracy of the two adjacent positioning plates in the same group. Then, the two adjacent horizontal plates in the same group are connected by the connecting component to connect multiple horizontal plates in the same group into one, thereby improving the stability of the horizontal plates during use.

[0013] Optionally, the connecting assembly includes a connecting rod that passes through the positioning block and the inner wall of the positioning groove.

[0014] By adopting the above technical solution, after the positioning of two adjacent horizontal plates in the same group is completed, the connecting rod is passed through the positioning block and the inner wall of the positioning groove. The connecting rod limits the two adjacent horizontal plates in the same group through the positioning block and the inner wall of the positioning groove, thereby improving the reliability of the connection between the two adjacent horizontal plates.

[0015] Optionally, the connecting assembly further includes a limiting part placed at the end of the connecting rod. The limiting part includes a limiting cylinder sleeved on the outer periphery of the connecting rod and a limiting plate placed on the outer ring wall of the limiting cylinder. The limiting plate and the connecting rod clamp two adjacent horizontal plates in the same group.

[0016] By adopting the above technical solution, after the connecting rod passes through two adjacent horizontal plates in the same group, the limiting sleeve is installed at both ends of the connecting rod, and the bottom of the limiting plate abuts against the top of the two adjacent horizontal plates. This reduces the possibility of the two adjacent horizontal plates rotating around the connecting rod, and further improves the stability of the installation of the two adjacent horizontal plates.

[0017] Optionally, the connecting assembly further includes a connecting cylinder spirally sleeved on the outer periphery of the connecting rod, wherein the connecting cylinder and the horizontal plate clamp the limiting cylinder.

[0018] By adopting the above technical solution, after the limiting cylinder is sleeved on the outer circumference of the connecting rod, the connecting cylinder is spirally sleeved on the outer circumference of the connecting rod. The limiting cylinder is clamped and limited by the connecting cylinder and the horizontal plate, thereby limiting the limiting plate and improving the working reliability of the limiting plate.

[0019] Optionally, the fixing assembly includes a fixing rod placed between two adjacent sets of the working platforms and several sets of fixing columns placed on the fixing rod. The several sets of fixing columns are distributed along the length direction of the fixing rod. The end of each set of fixing columns away from the fixing rod is connected to the adjacent horizontal plate. Each set of fixing columns and the adjacent horizontal plate form a triangular structure.

[0020] By adopting the above technical solution, when connecting two adjacent horizontal plates of two adjacent sets of work platforms, one end of each fixed column is connected to a fixed rod, and the other end of each fixed column is connected to the adjacent horizontal plate, thereby completing the connection between the two adjacent sets of horizontal plates. At the same time, since the fixed column and the horizontal plate form a triangular stable structure, the connection stability between the two adjacent sets of work platforms is further improved.

[0021] Optionally, each of the fixed posts is provided with a fixing cylinder at one end near the fixed rod, and the fixing cylinder is sleeved on the outer periphery of the fixed rod.

[0022] By adopting the above technical solution, when connecting the fixed column and the fixed rod, the fixed rod can be directly inserted into the fixed cylinder, thereby improving the convenience of connecting the fixed column and the fixed rod.

[0023] Optionally, fixing pins are inserted at both ends of the fixing rod, and the two fixing pins clamp several sets of fixing columns.

[0024] By adopting the above technical solution, after the fixing cylinder is inserted through the fixing rod, a fixing pin is inserted through the end of the fixing rod. The two fixing pins limit the fixing rod through the fixing cylinder, thereby improving the working stability of the fixing rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When climbing formwork installation is required, after installing the climbing mechanism on the pier sidewall, the individual working platforms are hoisted sequentially, allowing each platform to be installed on the pier sidewall via the climbing mechanism. Working platforms in the same group are distributed circumferentially along the pier axis. Adjacent working platforms in the same group are detachably connected via connecting components. After the installation of each group of working platforms is completed, other groups of working platforms are installed on the pier sidewall in a bottom-to-top sequence, and adjacent groups are detachably connected via fixing components. After the frame structure is installed, the formwork mechanism is installed on top of it. When the pier cross-section is large, the frame structure can be broken down into multiple working platforms, and the assembly of the frame structure can be reduced by installing each platform individually, thus improving the ease of assembly and reducing the space required for assembly, thereby enhancing the convenience of climbing formwork installation.

[0027] 2. When connecting two adjacent horizontal plates in the same group, bring the two horizontal plates close to each other and insert the positioning block into the corresponding positioning slot. The inner wall of the positioning slot is positioned by the positioning block to improve the positional accuracy of the two adjacent positioning plates in the same group. Then, the two adjacent horizontal plates in the same group are connected by the connecting component to connect multiple horizontal plates in the same group into one, thereby improving the stability of the horizontal plates during use.
