[0001] The utility model relates to the technical field of climbing formwork frames, in particular to a telescopic steel bar binding platform attached to the climbing formwork frame. Background Art

[0002] At present, in the construction process of super-high-rise core tubes, due to the tight construction period and the dense steel bars of super-high-rise core tube wall columns, the binding time is relatively long. When traditionally binding the steel bars of wall columns, the concrete pouring of the current floor slab must be completed, and after the concrete strength meets the requirements, steel pipes and other materials are used to build an operating platform. Personnel stand on the operating platform to tie the wall column steel bars. There are two problems with the traditional construction method: 1. Since it takes time to pour the concrete of the core tube floor slab of the current layer and for the concrete to reach a certain strength, the steel bars of the upper layer cannot be inserted and tied in advance, which affects the construction period. 2. There are many reserved openings in the core tube floor slab. The use of steel pipes and other materials to build the operating platform needs to be oriented according to the position of the reserved openings on each core tube floor slab, which is troublesome to operate.

DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] like Figures 1 to 7 As shown, a retractable steel bar binding platform attached to a climbing formwork comprises a climbing formwork 100, a horizontally arranged main beam 1 is installed on the climbing formwork 100, a pull-out cantilever beam 2 is installed in the main beam 1, specifically: two first pin holes 11 are provided at one end of the main beam 1 close to the steel springboard 4, two second pin holes 21 are provided at one end of the cantilever beam 2 close to the main beam 1, a pin column 3 is inserted into the first pin hole 11 and the adjacent and coaxial second pin hole 21, a limiting ring is provided at the head of the pin column 3, a through hole arranged along the radial direction of the pin column is provided at the tail of the pin column 3, an open pin 9 is inserted into the through hole.

[0024] A steel springboard 4 is laid flat on the cantilever beam 2. In order to prevent the steel springboard 4 from being stuck, a positioning hole 22 is opened at the top of the cantilever beam 2. A positioning column 41 is welded to the bottom end of the steel springboard 4, and the positioning column 41 is inserted into the positioning hole 22.

[0025] A main beam is installed on the climbing formwork, and a retractable cantilever beam is installed in the main beam. When the climbing formwork climbs, the cantilever beam is retracted into the main beam. When it is necessary to build a steel bar binding platform, the cantilever beam is pulled out from the main beam, and the steel springboard is laid flat on the cantilever beam. Since the support of the retractable steel bar binding platform is the climbing formwork, there is no need to wait until the concrete of the core tube floor of this layer reaches the use strength before building it, and there is no need to consider the reserved hole position on the core tube floor of this layer. In addition, the installation and operation of the cantilever beam and the steel springboard are simple and convenient.

[0026] The end of the cantilever beam 2 away from the main beam 1 is equipped with a detachable protective mechanism 5 for preventing workers from falling. The end of the cantilever beam 2 away from the main beam is welded with a socket ring 8. The detachable protective mechanism 5 includes two vertical poles 51, three horizontal poles 52, and a protective net 53. The bottom end of the vertical pole 51 is fixed with a socket rod 54, and the socket rod 54 is interference fit with the socket ring 8. The horizontal rod 52 is welded between adjacent vertical poles 51, and the protective net 53 is welded to the vertical poles 51 and the horizontal rod 52.

[0027] The cross-sections of the socket ring 8, the socket rod 54, and the vertical rod 51 are all circular. The outer diameter of the socket rod 54 is equal to the inner diameter of the socket ring 8, and the outer diameter of the socket rod 54 is smaller than the outer diameter of the vertical rod 51. In order to ensure that the socket rod 54 is safely and stably inserted into the socket ring 8, the length of the socket rod 54 is equal to the length of the socket ring 8. In order to facilitate the insertion of the socket rod 54 into the socket ring 8, the outer edge of the bottom end of the socket rod 54 is rounded.

[0028] In order to prevent the cantilever beam 2 from sagging at one end away from the main beam, the retractable steel bar binding platform also includes an iron chain 6, and an anti-slip hook is installed at both ends of the iron chain 6. The anti-slip hook at the head of the iron chain 6 is hooked on a lifting ring 101 installed on the climbing formwork 100. The cantilever beam 2 is screwed with an eye bolt 7 at one end away from the main beam, and the anti-slip hook at the tail of the iron chain 6 is hooked on the eye bolt 7.
