Embodiment

[0019] The following takes Nanjing Dingzheng Real Estate No.2011G38 plot project aerial corridor as an example. The underground height of this project is 13.75m, the ground height is 63.8m, and the total height is 77.55m. The height of the corridor truss is 2.3m, the span is 39m, the assembly elevation is -6.1m, and the lifting height is about 71m. If the existing technology is adopted, the estimated cost is about 750,000. After adopting the method of this example, the total cost is about 340,000 yuan, saving about 55% of the construction cost.

[0020] The method of this example is to divide the corridor truss into three sections, including a middle truss and two end trusses 6, and the two end trusses 6 can be directly assembled on the top surface 1 of the building as the basic support of the lifting platform. When assembling the end truss 6, the bottom of the foot 15 of the end truss 6 should be padded with a vibration-isolation support 5; The center of the top surface of ...

Abstract

The invention discloses a lifting platform for lifting a large-span high-altitude corridor truss. The lifting platform comprises supporting steel plates, a reinforced concrete pier is arranged at thetop surface of a building, and a ground anchor steel plate is embedded in the reinforced concrete pier. Seismic isolation supports are arranged on the supporting steel plates, and an end truss is located on the seismic isolation supports. A cross beam at the rear end of the end truss is connected with the ground anchor steel plate through a ground anchor tie rod. Hoisting platforms are separatelyinstalled on both sides of the top of the end truss. The hoisting platforms include support columns, and the bottom ends of the support columns and stand columns on both sides of the front end of theend truss are connected in a welded mode. The rear sides of the top ends of the support columns are connected with the cross beam at the rear end of the end truss in a welded mode through diagonal tierods. Horizontal suspension beams are welded to the front sides of the top ends of the support columns, and the bottoms of the horizontal suspension beams are connected with the bottoms of stand columns on the front side of the end truss in a welded mode through support rods. The inner sides of the horizontal suspension beams are connected with the middle part of a cross beam at the top of the end truss in a welded mode through diagonal ligaments. The lifting platform has good stability, can reduce the total weight of lifting, reduces the difficulty of lifting, and facilitates the butt jointafter lifting. The lifting platform is convenient to erect and dismantle, and is beneficial to controlling the construction cost.

Description

technical field [0001] The invention relates to a lifting platform for lifting a truss of a large-span high-altitude corridor, which belongs to the technical field of building construction. Background technique [0002] With the expansion of economic and cultural construction needs and the improvement of people's appreciation of architecture, long-span steel structures are more and more favored by designers due to their diverse forms, beautiful appearance, and good economy. It is applied to the roof structure of large public buildings such as airport buildings, convention and exhibition centers, stadiums, exhibition halls, and air corridors. [0003] In the prior art, when carrying out the construction of the long-span high-altitude corridor truss, the method of setting up temporary supports is adopted. Due to the long length of the corridor truss and the high height of the corridor truss, it is necessary to rent large machinery and a large number of tire frames to erect te...
