Description

A hook-type safety anti-tilt device

technical field

The utility model relates to a hook-type safety anti-tilt device, which is especially suitable for use when dismantling a cantilevered inner barrel frame of an integral steel platform.

Background technique

The integral steel platform formwork is the core technology of super high-rise building construction. After the construction of the concrete structure of the core tube of the building is completed, the integral steel platform formwork stops climbing and is removed. At this time, the formwork stays at a height of several hundred meters. The demolition operation brings great difficulties, and ensuring the stability of the formwork structure and the safety of the construction personnel during the demolition process is the focus and difficulty of the entire demolition work. For example, for the removal of the cantilevered inner cylinder frame, based on the complex structure of the core tube, the support structure of the inner cylinder frame in the core tube is unilaterally supported during design. One side of the last hanger body (step 7 of the inner barrel frame) is 500mm away from the wall and the other side is suspended in the air. In order to prevent the frame body from tipping over during the demolition process, according to the previous demolition scheme, as shown in Figure 1, the steel wire rope 8 is used to pull it obliquely. In this way, it is difficult for the construction personnel to control the frame body 7 during the operation process. Shaking, so the balance of the frame cannot be truly guaranteed, and there are certain potential safety hazards.

Utility model content

A hook-type safety anti-rolling device, comprising an L-shaped first steel plate connector and an inverted L-shaped second steel plate connector, the horizontal section of the first steel plate connector is fixedly connected to the wall, and the The horizontal section of the second steel plate connector is fixedly connected to the frame body,

The first steel plate connector and the second steel connector are hooked together, the vertical section of the first steel connector and the vertical segment of the second steel connector are respectively provided with connecting holes, and the two connecting holes pass through Bolted connection.

Further, the first steel plate connector is welded integrally with the wall embedded part.

Further, the frame body is a cantilevered inner barrel frame.

Further, the horizontal section of the second steel plate connector is fixedly connected to a bayonet part for clamping on the cantilevered inner cylinder frame, and the bayonet part includes a connecting plate and side parts fixed on both sides of the connecting plate. The corresponding positions of the two side plates are provided with long slotted holes along the horizontal direction, and stud bolts are installed between the long slotted holes of the two side plates.

Further, the first steel plate connector and the second steel plate connector are respectively welded with reinforcing ribs on the outside of the horizontal section.

The working principle of the utility model is that the hanging point on the upper part of the frame body is fixed by the hoisting equipment, and the side of the frame body against the wall is connected with the frame body through mutual hooking and bolt fixing between two steel plate connectors. When the shelving corbel is retracted, the two steel plate connectors are tensioned to ensure the stable balance of the frame body during the dismantling process. When dismantling the frame body, first remove the bolts between the two steel plate connectors, and then lift the frame body vertically by the hoisting equipment, and the first steel plate connector is separated from the second steel plate connector to realize the smooth removal of the frame body. The second steel plate connector adopts a bayonet part, and slotted holes are set on the two side plates, and the stud bolts are installed between the long slot holes, so that the bayonet part can be fixed on the square tube of the cantilevered inner cylinder frame .

Compared with the prior art, the utility model has the beneficial effects of:

The utility model can effectively prevent the cantilevered inner barrel frame from tipping inward, ensure the balance of the frame body during the dismantling process, prevent safety accidents, and ensure the safety of construction personnel.
