Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a hydraulic climbing formwork integral climbing and sliding device and method suitable for inclined wall construction. Background Technique

[0002] The hydraulic climbing formwork system is widely used in the construction of super high-rise core tube structures. This system is a complex system that integrates formwork, machinery, hydraulics, and automatic control technologies. It can be mainly divided into five parts: a formwork system, an operation platform system, an attached wall support system, a hydraulic climbing system, and an intelligent control system.

[0003] The hydraulic climbing formwork usually climbs vertically attached to the outer side of the core tube wall. However, when the core tube structure wall becomes an inclined wall that inclines inward, especially when several consecutive floors are inclined walls, this undoubtedly increases the difficulty of the hydraulic climbing formwork climbing. During the construction of the inclined wall, due to the inward inclination of the inclined wall section, the climbing guide rail is in an inclined state, and then the climbing formwork frame is correspondingly in an inclined state, and the inclination angle even reaches more than 8°, which is difficult to ensure the construction safety.

[0004] At present, the conventional method is to set up a temporary support structure that extends out of the wall in the inclined wall section, so that the climbing guide rail passing through the inclined wall section is in a vertical state, thereby ensuring that the climbing formwork frame is in a vertical state. After the inclined wall section is constructed and the corresponding straight wall section is poured, the hydraulic climbing formwork is disassembled in sections by means of a tower crane and then re-lifted to the straight wall section for climbing according to the normal process. The high-altitude disassembly and assembly operations greatly increase the risk coefficient, the construction process is more cumbersome, and it also has a certain impact on the construction period. In addition, when encountering consecutive multi-layer inclined walls, the construction distance between the vertically climbing frame and the wall becomes larger and larger, and the size of the temporary support structure also needs to be increased accordingly, which brings many inconveniences to the construction and is not conducive to the construction safety.

[0005] Therefore, it is necessary to study a hydraulic climbing formwork integral climbing and sliding device and method suitable for inclined wall construction to ensure the construction safety. Summary of the Invention

[0006] The present invention provides a hydraulic climbing formwork integral climbing and sliding device and method suitable for inclined wall construction. By adopting the method of adding a temporary support structure as the bearing device of the hydraulic climbing formwork and also serving as the horizontal sliding track of the hydraulic climbing formwork attachment device, the integral horizontal inward sliding and vertical upward climbing of the hydraulic climbing formwork in the inclined wall section can be realized through the attachment device, eliminating the cumbersome process of high-altitude disassembly and assembly of the hydraulic climbing formwork, reducing the impact on the construction period, improving the construction convenience, and greatly ensuring the construction safety.

[0007] To solve the above technical problems, the present invention includes the following technical solutions:

Except for the sliding condition, the attachment device of the hydraulic climbing formwork is fixed on the sliding track of the temporary support structure through safety pins. After the construction of the inclined wall of this floor is completed, the temporary operation platform is removed before the hydraulic climbing formwork can be lifted.

[0018] Step S2: Hook bolts are embedded at designated positions in the concrete of the inclined wall. When the concrete reaches the required strength and the hydraulic climbing formwork climbs up one floor height, a tensioning device is installed. One end of the chain block is connected to the front column of the triangular frame at the climbing formwork position, and the other end of the chain block is connected to the hook bolt. Through adjustment, the chains of each hoist are in a taut state. This process is the pre-tightening work. Then, the safety pins of the attachment device of the climbing formwork are pulled out, the hoist is pulled, at a uniform speed, and the climbing formwork is slowly horizontally slid inwards by a designated distance. After the sliding is in place, the attachment device of the hydraulic climbing formwork is reinserted with safety pins and fixed on the sliding track, and the construction of the inclined wall of the next floor is continued in the manner of Step S1.

[0019] Step S3: The upper inclined wall is constructed successively according to the methods of Step S1 and Step S2 until the hydraulic climbing formwork is slid to the initial position as a whole. The large formwork is reconnected to the formwork sliding device on the suspended formwork beam, and the core tube straight wall section above the inclined wall is constructed according to the conventional process.

[0041] Step S1: For the vertical wall section below the Nth floor, the hydraulic climbing formwork is constructed by climbing according to the conventional process. When constructing the N-story inclined wall, the hydraulic climbing formwork climbs to the top of the straight wall section below the inclined wall. Since the inclined wall is inclined inward, the distance between the inclined wall and the formwork is large, which is not convenient for construction workers to operate. Therefore, before constructing the inclined wall, a short temporary operating frame needs to be set up with the help of the upper frame of the hydraulic climbing formwork, and a tower crane is used to dismantle and lift the large formwork of the hydraulic climbing formwork. Embedded parts are set at the position of the inclined wall climbing formwork machine, and concrete is poured. After the curing is completed and the formwork is removed, a temporary supporting structure 1 is welded on the embedded parts to serve as a hydraulic climbing formwork bearing device and a horizontal sliding track of the hydraulic climbing formwork attachment device 2, so that the hydraulic climbing formwork of the inclined wall can slide inward horizontally as a whole; except for the sliding working condition, under other working conditions, the hydraulic climbing formwork attachment device 2 is fixed on the sliding track of the temporary supporting structure 1 by a safety pin. After the construction of the inclined wall of this floor is completed, the temporary operating frame is removed before the hydraulic climbing formwork can be lifted;

[0042] Step S2: Embed hook bolts at specified positions in the concrete of the inclined wall. When the concrete reaches the required strength and the hydraulic climbing formwork climbs up one floor height, install the tie device. Connect one end of the chain hoist to the front column 4 of the tripod of the climbing formwork position, and connect the other end of the chain hoist to the hook bolt. Through adjustment, make each hoist chain in a taut state. This process is the pre-tightening work. Then pull out the safety pin of the climbing formwork attachment device 2, pull the hoist, at a unified speed, and slowly horizontally slide the climbing formwork inward by a specified distance. After sliding in place, reinsert the safety pin of the hydraulic climbing formwork attachment device 2 and fix it on the sliding track, and continue the construction of the inclined wall of the next floor in the manner of Step S1.

[0043] Step S3: Construct the upper inclined wall in sequence according to the methods of Step S1 and S2 until the hydraulic climbing formwork slides as a whole to the initial position. Reconnect the large formwork to the sliding device of the upper formwork of the suspended formwork beam, and construct the straight wall section of the core tube above the inclined wall according to the conventional process.
