Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic climbing formwork systems, and in particular to a hydraulic climbing formwork system for high pier construction. Background Technology

[0002] In the construction of high piers, hydraulic climbing formwork systems have become commonly used construction equipment due to their ability to adapt to continuous pouring, automatic climbing, and precise formwork positioning. The corbel, as the supporting and load-bearing component of the hydraulic climbing formwork system, is responsible for connecting the climbing formwork frame and the pier body in the construction of high piers, ensuring the stability and safety of the construction process.

[0003] Existing horizontal support structures for corbels are mostly fixed steel plates. The connection between the horizontal beams of the climbing formwork and the corbels requires bolts for hard fixing. During installation, the connecting holes at the bottom of the horizontal beams must be precisely aligned with the bolt holes on the corbel steel plates before tightening the bolts one by one. If there is a deviation in the position of the horizontal beams, all bolts must be loosened first, and the horizontal beams must be manually pried open with a pry bar for adjustment. After adjustment, the hole positions must be recalibrated and the bolts tightened. This type of structure has obvious defects: the horizontal beam positioning and adjustment process is cumbersome, the hole alignment requires repeated trial and error, and deviation correction relies on manual prying, making it impossible to achieve rapid lateral position correction. Especially in scenarios with multiple corbels for spaced support, the position adjustment of each corbel is difficult to synchronize, making it difficult to meet the efficient and precise construction requirements of hydraulic climbing formwork systems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a hydraulic climbing formwork system for high pier construction, which can improve the efficiency of adjustment and correction of the connection and positioning between the climbing formwork frame and the corbel.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A hydraulic climbing formwork system for high pier construction includes:

[0007] A climbing formwork frame, which is used to be installed on a high pier and climb along the height direction of the high pier; the climbing formwork frame has a horizontal beam frame that extends along a first horizontal direction.

[0008] A support assembly for connecting to and being supported by the high piers, and for supporting the climbing formwork frame; the support assembly has a horizontal support structure that extends along a first horizontal direction;

[0009] A sliding guide mechanism includes a slide rail and a slider. The slide rail is mounted on the upper surface of the horizontal support structure and supported by the horizontal support structure. The slide rail extends along a first horizontal direction. The slider is connected to the bottom of the horizontal beam and slides in cooperation with the slide rail.

[0010] A locking element is connected to the horizontal beam frame and is used to lock the horizontal beam frame to the slide rail.

[0011] Furthermore, the locking element is a first screw, and the slide rail and the horizontal support structure are locked together by the first screw.

[0012] Furthermore, the horizontal beam frame has a first through hole extending vertically, and the slider has a second through hole extending vertically. The first through hole and the second through hole are coaxially arranged and connected by a second screw.

[0013] Furthermore, the horizontal beam frame has a third through hole, the slide rail has a fourth through hole extending vertically, and the horizontal support structure has a fifth through hole extending vertically; the third through hole, the fourth through hole, and the fifth through hole are coaxially arranged and locked by the first screw.

[0014] Furthermore, the support assembly also has a vertical support structure, which is connected to the bottom of the horizontal support structure to support the horizontal support structure; the vertical support structure extends along a second horizontal direction perpendicular to the first horizontal direction to abut against and be supported by the high pier.

[0015] Furthermore, the support assembly also includes an embedded part having a fixed end for embedding inside the pier.

[0016] Furthermore, the embedded part is provided with a connection interface, which extends outward from the inside of the pier and is used for the end of the vertical support structure to be detachably inserted.

[0017] Furthermore, the end of the vertical support structure is provided with an elastic metal sheet, which is attached to the outer periphery of the end of the vertical support structure. The elastic metal sheet is used to tightly abut against the inner wall of the connection interface through its own elastic deformation.

[0018] Furthermore, the support components are provided in multiple ways, and the multiple support components are arranged at intervals along the first horizontal direction; each support component is provided with at least one horizontal support structure, and each horizontal support structure is connected to the bottom of the slide rail and supports the slide rail.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The climbing formwork is used to install on high piers and climb along the height of the piers. The climbing formwork has a horizontal beam frame that extends along the first horizontal direction, so that the climbing formwork can adapt to the height requirements of layered pouring of high piers, while providing a flat bearing surface for formwork, equipment and personnel, and ensuring uniform load distribution.

[0021] 2. The support components are used to connect to and be supported by the high piers, and to support the climbing formwork, so that the load of the climbing formwork is stably transferred to the high piers, which can limit the lateral displacement of the climbing formwork, avoid swaying and ensure safety.

[0022] 3. Based on the fact that the support component has a horizontal support structure that extends along the first horizontal direction, it can provide a continuous support surface for the sliding guide mechanism, prevent the slide rail from tilting and breaking, and correspond to the horizontal beam frame in parallel to ensure smooth load transfer.

[0023] 4. The sliding guide mechanism includes a slide rail and a slider. The slide rail is installed on the upper surface of the horizontal support structure and supported by the horizontal support structure. The slide rail extends along the first horizontal direction, so that the slide rail relies on the support to keep straight and flat, avoiding deformation. At the same time, it provides a fixed motion trajectory for the slider to prevent it from deviating from the direction when the climbing mold frame moves.

[0024] 5. Based on the slider being connected to the bottom of the horizontal beam frame and slidingly engaging with the slide rail, the climbing formwork frame can be flexibly adjusted along the first horizontal direction, adapting to changes in the cross-section of the high pier without dismantling the frame, thus improving efficiency and reducing adjustment friction and damage risks.

[0025] 6. Based on the connection between the locking component and the horizontal beam frame, and used to lock the horizontal beam frame to the slide rail, the climbing formwork can be quickly fixed after the position is adjusted, preventing accidental sliding during construction that could lead to deviations in the pouring dimensions. The detachable design also facilitates subsequent adjustments. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See Figures 1-3 A preferred embodiment of the present invention provides a hydraulic climbing formwork system for high pier construction, comprising: a climbing formwork frame 1, a support assembly 2, a sliding guide mechanism 3, and a locking component 4.

[0034] The climbing formwork scaffold 1 is installed on a high pier and climbs along the height of the pier. Based on the application of this hydraulic climbing formwork system for high pier construction, it is mainly used for concrete pouring of high pier structures such as bridges and buildings, providing a movable support platform for the formwork. The climbing formwork scaffold 1 provides the core load-bearing capacity of the entire system, needing to withstand the loads of the formwork, equipment, and workers, ensuring structural stability during construction. The climbing formwork scaffold 1 is preferably a welded frame structure, with reinforcing plates at the frame joints and anti-corrosion treatment on the surface to adapt to the outdoor construction environment. The climbing formwork scaffold 1 has a horizontal beam frame 101, which extends along a first horizontal direction. As a key load-bearing component of the climbing formwork scaffold 1, the horizontal beam frame 101's design extending along the first horizontal direction provides an installation foundation for the sliding guide mechanism 3, while ensuring uniform load distribution along the horizontal direction.

[0035] Support component 2 connects to and is supported by the high pier, and supports the climbing formwork frame 1. As a connecting bridge between the climbing formwork system and the high pier, it directly affects the overall safety of the climbing formwork system. Support component 2 is preferably modular in design for easy transportation and on-site assembly. Support component 2 has a horizontal support structure 201 that extends along a first horizontal direction. It can be understood that the horizontal support structure 201 obtains support force through a stable connection with the high pier, and then transfers the load of the climbing formwork frame 1 to the high pier. Its extension along the first horizontal direction corresponds to and cooperates with the horizontal beam frame 101, providing a stable foundation for sliding adjustment.

[0036] The sliding guide mechanism 3 is used to adjust the climbing formwork 1 along the first horizontal direction to meet the precise adjustment requirements of the formwork position during high pier construction. The sliding guide mechanism 3 includes a slide rail 301 and a slider 302. The slide rail 301 is installed on the upper surface of the horizontal support structure 201 and is supported by the horizontal support structure 201, extending along the first horizontal direction. The slide rail 301 is preferably made of high-strength alloy steel. The slider 302 is connected to the bottom of the horizontal beam frame 101 and slides in cooperation with the slide rail 301. The inner side of the slider 302 has a groove adapted to the slide rail 301.

[0037] The locking component 4 is connected to the horizontal beam frame 101 and is used to lock the horizontal beam frame 101 to the slide rail 301. It is fixed after the climbing formwork scaffold 1 is adjusted to the target position, preventing accidental sliding during construction. The locking component 4 is preferably a high-strength fastener, and its structure must be compatible with the connection method of the horizontal beam frame 101 and the slide rail 301 to ensure no loosening gaps after locking. It can be understood that the locking component 4 is a key component for ensuring construction safety. Through reliable locking, it fixes the relative movement of the sliding guide mechanism 3, ensuring the climbing formwork scaffold 1 remains stable under construction loads.

[0038] During construction, the support assembly 2 is first fixedly connected to the high pier to ensure that the horizontal support structure 201 extends smoothly along the first horizontal direction. Then, the slide rail 301 is installed on the upper surface of the horizontal support structure 201, and the position of the slide rail 301 is adjusted to be consistent with the first horizontal direction. Next, the slider 302 is fixed to the bottom of the horizontal beam frame 101 of the climbing formwork scaffold 1, and the climbing formwork scaffold 1 is placed on the support assembly 2 through the cooperation of the slider 302 and the slide rail 301. According to the construction requirements, the locking piece 4 is loosened, and the climbing formwork scaffold 1 is pushed to move horizontally along the slide rail 301 to the target position. Then, the locking piece 4 is operated to lock the horizontal beam frame 101 to the slide rail 301. As the construction height of the high pier increases, the climbing formwork scaffold 1 is driven to climb along the height direction of the high pier through the hydraulic drive system. After climbing to the position, the above horizontal adjustment and locking steps are repeated, and the next stage of construction can be carried out.

[0039] The climbing formwork scaffold 1 is installed on a high pier and climbs along the height of the pier. The climbing formwork scaffold 1 has a horizontal beam 101 extending along a first horizontal direction, allowing it to adapt to the height requirements of layered pouring on the high pier. It also provides a flat bearing surface for the formwork, equipment, and personnel, ensuring uniform load distribution. The support assembly 2 connects to and is supported by the high pier, supporting the climbing formwork scaffold 1. This ensures stable load transfer to the high pier, limits lateral displacement of the climbing formwork scaffold 1, and prevents swaying, ensuring safety. The support assembly 2 has a horizontal support structure 201 extending along the first horizontal direction, providing a continuous support surface for the sliding guide mechanism 3, preventing the slide rail 301 from tilting and breaking. It also corresponds parallel to the horizontal beam 101, ensuring smooth load transfer. The sliding guide mechanism 3 includes a slide rail 301 and a slider 302. The slide rail 301 is installed on the upper surface of the horizontal support structure 201 and is supported by the horizontal support structure 201. The slide rail 301 extends along the first horizontal direction, allowing the slide rail 301 to remain straight and flat with the support, avoiding deformation. At the same time, it provides a fixed movement trajectory for the slider 302, preventing the climbing formwork 1 from deviating from its direction when it is translated. The slider 302 is connected to the bottom of the horizontal beam frame 101 and slides in cooperation with the slide rail 301, allowing the climbing formwork 1 to be flexibly adjusted along the first horizontal direction. It can adapt to changes in the cross-section of the high pier without dismantling the frame, improving efficiency and reducing the risk of adjustment friction and damage. The locking member 4 is connected to the horizontal beam frame 101 and is used to lock the horizontal beam frame 101 to the slide rail 301, so that the climbing formwork 1 can be quickly fixed after the position is adjusted, preventing accidental sliding during construction that could cause deviations in the pouring dimensions. The detachable design also facilitates subsequent adjustments.

[0040] Preferably, the locking element 4 is a first screw, which is preferably a high-strength bolt, and is equipped with an anti-loosening nut and a flat washer. Threaded holes are provided at corresponding positions on the horizontal support structure 201 and the slide rail 301. After the first screw passes through the threaded hole, it is tightened with the nut, and the slide rail 301 and the horizontal support structure 201 are locked together by the first screw. It can be understood that using the first screw as the locking element 4, and achieving reliable fixation through the preload of the threaded connection, not only prevents relative sliding between the slide rail 301 and the horizontal support structure 201, but also facilitates disassembly and adjustment during construction.

[0041] Preferably, the horizontal beam 101 has a first through hole 102 extending vertically, and the slider 302 has a second through hole 303 extending vertically. The first through hole 102 and the second through hole 303 are coaxially arranged and connected by a second screw 5. After the second screw 5 is tightened, the head of the screw fits against the upper surface of the horizontal beam 101, and the nut fits against the lower surface of the slider 302, forming a bidirectional fastening. It can be understood that the coaxial through hole design ensures the connection stability between the horizontal beam 101 and the slider 302, and the rigid connection of the second screw 5 enables the two to move synchronously, avoiding relative displacement during sliding. At the same time, the vertical connection does not affect the horizontal movement of the slider 302 along the slide rail 301.

[0042] Preferably, the horizontal beam frame 101 has a third through hole 103, the slide rail 301 has a fourth through hole 304 extending vertically, and the horizontal support structure 201 has a fifth through hole 202 extending vertically. The third through hole 103, the fourth through hole 304, and the fifth through hole 202 are coaxially arranged and locked by a first screw. The first screw passes through the three holes in sequence and is tightened with a nut, forming a rigid connection between the horizontal beam frame 101, the slide rail 301, and the horizontal support structure 201. This multi-layer coaxial locking design firmly fixes the three components into a whole, significantly improving the system's vibration resistance, and is particularly suitable for scenarios involving strong winds or mechanical vibrations during high-pier construction, ensuring no loosening gaps after locking.

[0043] Preferably, the support assembly 2 further includes a vertical support structure 203, which is connected to the bottom of the horizontal support structure 201 to support the horizontal support structure 201. The vertical support structure 203 extends along a second horizontal direction perpendicular to the first horizontal direction to abut against and be supported by the pier. The vertical support structure 203 is preferably a rectangular steel pipe, the top of which is welded to the bottom of the horizontal support structure 201, and a flat support plate is welded to the bottom to increase the contact area with the pier. The length of the vertical support structure 203 is determined according to the distance between the pier and the horizontal support structure 201 to ensure that it abuts tightly against the surface of the pier after extension. It can be understood that the vertical support structure 203 extends along the second horizontal direction to form lateral support, effectively resisting the bending deformation of the horizontal support structure 201, and further dispersing the load through abutment against the pier, thereby improving the overall stability of the support assembly 2.

[0044] Preferably, the support component 2 further includes an embedded part 204, which has a fixed end 205 for embedding inside the pier. It can be understood that the embedded part 204 forms an integral structure with the pier concrete through the fixed end 205, providing a reliable anchoring point for the support component 2. Compared to temporary fixing methods, it can withstand greater vertical and horizontal loads, ensuring that the support component 2 does not detach during pier construction.

[0045] Preferably, the embedded part 204 is provided with a connection interface 206, which extends outward from the inside of the pier and is used for detachable insertion of the end of the vertical support structure 203. The connection interface 206 is a sleeve made of seamless steel pipe, the inner diameter of which is slightly larger than the outer diameter of the end of the vertical support structure 203, and preferably has multiple positioning holes on the pipe wall. It can be understood that the detachable insertion connection facilitates the quick installation and removal of the support component 2, the sleeve design ensures the coaxiality of the vertical support structure 203 and the embedded part 204, and the positioning holes can be further fixed by pins to prevent the vertical support structure 203 from accidentally coming out.

[0046] Preferably, the end of the vertical support structure 203 is provided with an elastic metal sheet 207. The elastic metal sheet 207 is fitted to the outer periphery of the end of the vertical support structure 203, and is used to tightly abut against the inner wall of the connection interface 206 through its own elastic deformation. One end of the metal sheet is welded to the end, and the other end is slightly raised outward to form an elastic contact portion. It can be understood that the elastic metal sheet 207 fills the gap between the vertical support structure 203 and the connection interface 206 through deformation, forming an interference fit and ensuring the tightness of the connection.

[0047] Preferably, multiple support components 2 are provided, and the multiple support components 2 are arranged at intervals along the first horizontal direction. Each support component 2 has at least one horizontal support structure 201. The number of support components 2 is determined according to the length of the climbing formwork frame 1, and preferably one support component 2 is arranged at 2-meter intervals. Each horizontal support structure 201 is connected to the bottom of the slide rail 301 and supports the slide rail 301. The top elevation of each horizontal support structure 201 is consistent to ensure that the slide rail 301 remains horizontal after installation. It can be understood that the interval distribution of multiple support components 2 distributes the load of the slide rail 301 and the climbing formwork frame 1 to multiple support points, avoiding excessive force on a single support component 2, while ensuring the straightness of the slide rail 301 and ensuring smooth sliding of the slider 302.
