Device for reinforcing tower crane in coastal zone

Abstract

The invention relates to a device for reinforcing a tower crane in a coastal zone. The device is characterized by consisting of a plurality of connection rods, a plurality of connection pieces, a plurality of supporting rods, a plurality of steel ropes, a plurality of rectangular sleeves and a wind damper, wherein the rectangular sleeves are fixedly sleeved on a tower crane body, and the diameters of the rectangular sleeves are sequentially reduced from bottom to top; the steel ropes are connected between the adjacent rectangular sleeves; the wind damper is connected to the tower crane body by supporting the steel ropes; a wind damper body is positioned in the top rectangular sleeve and is in contact with hydraulic devices around the top rectangular sleeve; the supporting rods are arranged between the bottom rectangular sleeve and the ground and are connected with the connection rods arranged on the ground; and the connection rods are connected with the supporting rods through the connection pieces. By the device, if the height of the tower crane is greater than an independent height, the rectangular sleeves are arranged at the periphery of the tower crane, and the wind damper is arranged in the top rectangular sleeve; by the wind damper, most energy of wind can be counteracted; the swing degree of the tower crane is reduced; and the tower crane can be balanced.

Description

technical field [0001] The invention relates to a tower crane reinforcing device in a coastal area. Background technique [0002] Tower cranes play a pivotal role in the process of my country's modernization, but due to its own characteristics, once a tower crane collapse accident occurs, it will cause incalculable consequences in terms of personnel and economy. In coastal areas, considering the frequent typhoons and high wind intensity, when strong winds strike, tower cranes are likely to collapse under the force of the wind. The traditional tower crane uses the wall-attached rods to connect with the building for reinforcement. When the wind force is applied, the wall-attached rods are both tensioned and compressed. Sometimes the wall-attached rods have too large a slenderness ratio or the connection method is not standardized, which will lead to the collapse of the tower crane. . And in many cases, there is a difference in height and distance between the building and the...

Problems solved by technology

The traditional tower crane uses the wall-attached rods to connect with the building for reinforcement. When the wind force is applied, the wall-attached rods are both tensioned and compressed. Sometimes the wall-attached rods have too large a slenderness ratio or the connection method is not standardized, which will lead to the collapse of the tower crane.

Moreover, in many cases, there is a gap between the height and distance between the building and the tower crane, so that the wall-attached pole cannot be used.

When some industrial or steel structure buildings are built, if wall-attached poles are used on the building surface for tower crane reinforcement, the calculation and approval of the engineering design party is required, and the process is cumbersome.
