Description

Technical Field

[0001] The utility model relates to the technical field of super high-rise core tubes, in particular to a super high-rise variable-section climbing formwork pad support. Background Art

[0002] At present, during the construction of super-high-rise core tubes, the climbing formwork will involve the overall inward retraction of the floor facade when climbing. The wall thickness of a conventional core tube will decrease with the change in height. When the thickness of the exterior wall is small, it is only necessary to adjust the vertical anti-overturning equipment of the guide rail to meet the lifting requirements; when the thickness change is large, special transition pads should be used to assist the climbing formwork in climbing, so that the frame can climb to the retracted section. At the same time, the climbing formwork pads are prone to deformation when loaded, resulting in certain safety hazards in the climbing formwork. During operation, the climbing formwork wall pads are subject to greater stress and there is a certain risk of deformation.

[0003] Existing super-high-rise core tube construction often presents the challenge of variable cross-sections. As the core tube structure rises, the thickness of the core tube's exterior walls shrinks, hindering the climbing formwork's ascent. To ensure smooth ascent, pads are installed at the wall attachments on the variable cross-section floors. These pads are connected to the structural walls or beams via through-wall bolts. The key issue during the climbing formwork ascent is the proper positioning of the guide rails. Only when the guide rails have properly ascended to the upper wall attachments can the forces acting on the structure be smoothly transferred to the attachments during ascent. Therefore, during the inclined ascent of variable cross-sections, it is important to ensure that the guide rails are properly pressed down onto the load-bearing blocks of the top wall attachments. The climbing formwork can accommodate a 50mm variable cross-section per ascent. Similarly, after three inclined ascents of a 150mm variable cross-section, the structure will return to its normal climbing state.

[0004] In existing super-high-rise variable-section hydraulic climbing formwork construction technology, the frame is tilted during climbing. When the formwork is significantly retracted, spacers are installed, but these spacers are connected to the wall using only load-bearing bolts. These load-bearing bolts are subject to significant shear and tensile stresses, and the spacers rely solely on friction to prevent displacement. This method employs a single load-bearing mode, making both the load-bearing bolts and spacers susceptible to deformation and displacement during the climbing formwork. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the existing technology of super-high-rise variable-section hydraulic climbing formwork construction technology, in which the frame is in an inclined state when climbing, and pads are set when the inward retraction is large, but the pads are only connected to the wall surface with load-bearing bolts. The load-bearing bolts are subjected to large shear stress and tensile stress, and the pads rely only on friction to prevent them from displacement. This method has a single load-bearing mode, and the load-bearing bolts and pads are prone to deformation and displacement when the climbing formwork climbs. Therefore, a super-high-rise variable-section climbing formwork pad support is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A super-high-rise variable-section climbing formwork pad support, comprising a support body, the support body comprising a back plate, side plates fixedly connected to both sides of the back plate, the tops of the two side plates fixedly connected to the same top plate, the bottom side of the top plate fixedly connected to a panel, threaded holes are provided in the interiors of the back plate and the panel, a through-wall bolt is provided in the interiors of the threaded holes, and a support assembly for supporting the pad is provided on the top of the top plate;

[0008] A bottom plate is fixedly connected between the two side plates, and a control component for controlling the support height is arranged inside the bottom plate.

[0009] In one possible design, the support assembly includes two symmetrically arranged support fixing bolts rotatably connected to the top of the top plate, the internal threads of the support fixing bolts pass through a support steel column, and the top of the support steel column is fixedly connected to a pad base.

[0010] In one possible design, the control assembly includes a screw threaded through the inside of the base plate, the top of the screw is rotatably connected to a limit plate, the bottom of the screw is fixedly connected to an adjustment block, and the limit plate is located directly below the supporting steel column.

[0011] In a possible design, a slider is fixedly connected to one side of the limiting plate, a sliding groove is provided on an inner wall of one side of the back plate, and the slider is slidably connected inside the sliding groove.

[0012] In one possible design, the bottom of the top plate is fixedly connected to two symmetrically arranged vertical rods, one side of the limit plate is fixedly connected to a connecting block, the connecting block is located between the two vertical rods, pointers are fixedly connected on both sides of the connecting block, and one side of the vertical rod is provided with a scale line for use with the pointer.

[0013] In a possible design, rectangular through holes are formed inside the side panels, back panel, and top panel.

[0014] In this application, the pad support is composed of five parts, among which the through-wall bolts are used to fix the support in the structure. The entire support body is made of high-strength steel and is cabinet-shaped; the supporting fixing bolts are used to fix the steel columns between the support and the pad; the supporting steel columns are used to vertically support the pad pedestal and the upper pad; the pad pedestal is connected to the supporting steel columns and the pad on both sides to carry the upper pad. The support can improve the force mode of the pad system, reduce the force on the load-bearing bolts in the pad, thereby reducing the deformation risk of the load-bearing bolts and the pad, and increasing the safety factor during the climbing process of the climbing formwork;

[0015] At the same time, in order to ensure that the heights of the two pad bases remain consistent, you can first rotate the adjustment block when making adjustments. The adjustment block drives the screw to rotate, and the screw drives the slider to move up and down. At this time, the slider drives the limit plate to move up and down, and the limit plate drives the connecting block to move up and down. The connecting block drives the two pointers to move up and down. The height of the limit plate can be changed according to the indication of the scale line. At this time, rotate the support fixing bolt so that the bottom of the supporting steel column contacts the limit plate. At this time, the heights of the two pad bases can be ensured to remain consistent, which is convenient for the stability of subsequent support.

[0016] Beneficial effects: Improved stress mode and increased safety: The designed pad support structure, especially the main body and supporting steel columns made of high-strength steel, effectively improves the stress mode of the pad system. This design reduces the stress on the load-bearing bolts in the pad, thereby reducing the deformation risk of the load-bearing bolts and pads, and significantly improving the safety factor during the climbing formwork climbing process.

[0017] Adjustable height to ensure stability: The adjustment mechanism in this application allows the height of the pad base to be precisely adjusted by rotating the adjustment block. This function ensures that the height of the two pad bases can remain consistent even in different working conditions or uneven ground, thereby ensuring the stability of subsequent support and avoiding safety hazards caused by height differences.

[0018] Easy to operate and maintain: The process of adjusting the height of the pad base is simple and intuitive. It can be completed by turning the adjustment block and observing the position of the pointer on the scale line. This design not only simplifies the operation process, but also facilitates daily maintenance and inspection, thereby improving work efficiency.

[0019] Strong adaptability and wide application: The structural design of the pad support is reasonable and can adapt to a variety of different construction environments and needs. Whether it is high-rise buildings, bridge construction or other large-scale projects, this application can provide stable and reliable support solutions.

[0020] Improve project quality and extend service life: By optimizing the force-bearing mode and improving support stability, this application helps to improve the overall project quality. At the same time, the use of high-quality materials such as high-strength steel also extends the service life of the support and reduces long-term maintenance costs.
