When the construction of the concrete main body structure is finished, the construction integrated platform is detached at high altitude, so that high altitude operation has certain safety risks and low working efficiency. In order to meet the requirements of the construction integrated platform on the type of ground disassembly and expansion construction operation after the construction of the concrete main body structure is completed, the supporting lifting system is required to have a descending function, however, the existing top die self-lifting supporting system does not have the descending function, in the embodiment, the first turning claw 3.1.1 is provided with a locking mechanism in a matching manner to limit the rotation of the first turning claw, so that the climbing frame 4 can descend relative to the bearing piece 3, the construction integrated platform is convenient to disassemble below on one hand, and on the other hand, an operation surface can be provided for secondary structure, external wall painting and other operations.
In addition, the carrier main body 3.1 is also provided with a shackle 3.6, and the shackle 3.6 is matched with the hoisting mechanism so as to hoist the carrier main body 3.1.
The jacking process of the jacking supporting system of the jacking mould is as follows (comprising two large jacking steps of the supporting frame 5 and the climbing frame 4).
Referring to fig. 7a to 7c, when the telescopic mechanism 6 is in an extension motion (the outer rod is extended relative to the inner rod), the lower flange 6.2 of the telescopic mechanism is gradually contacted with the bottom of the support frame 5, and the upper flange 6.1 of the telescopic mechanism is gradually separated from the spring box 5.2, so that the lower flange 6.2 supports the support frame 5 to continuously rise in an extension motion, and the bottom of the support frame 5 and the lower flange 6.2 can slide under external force. During the movement, the load of the construction steel platform 1 is transferred to the telescopic mechanism 6 via the upper flange 6.1. The head of the telescopic mechanism 6 adopts a spherical hinge structure 6.3 to ensure the self-centering effect in the telescopic movement. When the supporting frame 5 rises to the proper position, the telescopic mechanism 6 makes retraction movement (namely the outer rod slightly moves downwards for a certain distance), so that the inner claw shoes 5.1.1 and the first turning claw 3.1.1 of the supporting frame 5 are simultaneously attached to the common bearing force, and at the moment, the supporting frame 5 is hung on the bearing member 3. Of course, when the retraction movement is performed, if the inner claw shoes 5.1.1 and the first turning claws 3.1.1 of the supporting frame 5 cannot be bonded in multiple planes due to installation deviation, overlarge structural construction deviation and large deformation under large load in construction, the positions of the supporting frame 5 on the lower flange 6.2 can be adjusted through external force so as to realize that the inner claw shoes 5.1.1 and the first turning claws 3.1.1 are bonded in multiple planes simultaneously to bear force together. The continuous retraction realizes gradual lamination of the upper flange 6.1 and the spring box 5.2, and after the jacking is finished, the load of the construction steel platform 1 is sequentially transferred to the upper flange 6.1, the supporting frame 5, the bearing piece 3 and the turnover concrete structure attachment piece 2 through the supporting upright posts 7 until reaching the concrete main structure. In the jacking process, the load of the construction steel platform 1 is sequentially transferred to the upper flange 6.1, the spherical hinge structure 6.3, the bottom of the climbing frame 4, the second turning claw, the bearing piece 3 and the turnover concrete structure attachment piece 2 through the supporting upright post 7 until the construction steel platform is in a concrete main structure (the jacking of the climbing frame 4 is specifically depicted).
Referring to fig. 8a to 8c, when the support frame 5 is lifted to the upper layer of the bearing member 3, the climbing frame 4 can be lifted to move upwards through the telescopic mechanism 6. The second turning claw of the climbing frame 4 is contacted with the outer claw boots 3.4.1 of the bearing piece 3 in the lifting process of the climbing frame 4, so that the second turning claw is turned over inside the climbing frame 4, the second turning claw is gradually separated from contact with the outer claw boots 3.4.1 and turned over under self gravity when the climbing frame 4 continuously ascends, and meanwhile, the second turning claw is in a horizontal state in a natural state through the limit of the top block. Then, the telescopic mechanism 6 extends (i.e. the inner rod moves downwards) so as to drive the climbing frame 4 to descend, and when the self-centering structure of the second turning claw and the outer claw boot 3.4.1 of the climbing frame 4 is used for realizing the falling position, the position deviation can be eliminated, and the self-centering is in a plane contact state. In the motion process, the spherical hinge structure 6.3 is in a free sliding and rotating state, so that the second turning claw and the outer claw boot 3.4.1 are simultaneously attached to each other for bearing force after the lifting is finished. Of course, the lifting can be performed as desired by non-whole layers. The lifting function enables the climbing frame 4 to be mounted centrally on the support 3 (this section specifically describes the lifting of the support frame 5).
The self-lifting supporting system for the top die has the following beneficial effects:
1. because the height of the bearing main body 3.1 is higher than that of the concrete wall layer by layer, at least two rows of through holes are arranged in the height direction of the bearing main body 3.1 for the fasteners to pass through, compared with the bearing main body 3.1 with small volume in the prior art, the self-lifting support system is easy to be attached to the side surface of the concrete wall;
2. because the bearing part main body 3.1 is arranged at a layer height corresponding to the concrete wall body, compared with the small-volume wall-attached support in the prior art, the bearing area is greatly increased, and therefore, the overall structural strength of the bearing part 3 can be improved.
The utility model also provides a bearing piece of the top die self-lifting supporting system.
