Description

Super high-rise variable-section climbing die pad support

Technical Field

The utility model relates to the technical field of super high-rise core barrels, in particular to a super high-rise variable-section climbing formwork cushion support.

Background

At present, the construction of the super high-rise core tube can relate to the integral adduction state of the floor elevation when the climbing formwork climbs. The wall thickness of a conventional core barrel will decrease with height. When the thickness of the outer wall is small, the lifting requirement can be met by only adjusting the vertical anti-overturning equipment of the guide rail, and when the thickness variation is large, a special excessive cushion block is adopted to assist the climbing die to climb, so that the frame body climbs to the contracted section. Meanwhile, the climbing form cushion block is easy to deform under the action of load, so that certain potential safety hazards exist in the climbing form. When the climbing form wall-attached cushion block works, the stress on the climbing form wall-attached cushion block is large, and a certain deformation risk exists.

The prior super high-rise core tube construction is generally accompanied with the problem of variable cross section, and the thickness of the outer wall of the core tube is shrunk along with the rising of the core tube structure, so that the climbing formwork climbing is influenced by the shrinkage of the cross section of the wall body. In order to ensure that the climbing formwork climbs smoothly, a base plate is arranged at the variable cross-section floor wall attaching device, and the cushion block is connected with the structural wall body or the beam body through a wall penetrating bolt. The core problem in the climbing process of the climbing formwork is that the guide rail is normally positioned, and only if the guide rail is normally climbed to the upper wall attaching device, the stress in the climbing process of the frame body can be smoothly transmitted to the wall attaching device through the guide rail. Therefore, when the variable cross section climbs obliquely, attention needs to be paid to whether the guide rail is normally pressed down on the bearing block of the top wall attaching device. The climbing formwork can digest the variable cross-section size of 50mm every climbing, and the like, and after 3 times of inclined climbing, the 150mm variable cross-section is recovered to a normal climbing state.

In the existing super high-rise variable-section hydraulic climbing formwork construction technology, a frame body is in an inclined state when climbing, a cushion block is arranged when shrinking inwards is large, and the cushion block is connected with a wall surface only by using a bearing bolt. The bearing bolt is subjected to larger shear stress and tensile stress, and the cushion block is prevented from displacement only by virtue of friction force. The method has a single bearing mode, and the bearing bolts and the cushion blocks are easy to deform and displace when the climbing formwork climbs.
