Construction method for reversed stepped special-shaped steel structure

Abstract

The invention discloses a construction method for a reversed stepped special-shaped steel structure. The construction method comprises the following steps: 1) preparing a supporting part which comprises a jack, a bottom cross beam and a supporting rack, wherein the bottom cross beam comprises two parallelly arranged cross beam bodies, and the supporting rack comprises a bottom segment, a top segment and a plurality of middle segments; 2) mounting the bottom cross beam on a lower building; 3) mounting the supporting rack: mounting the bottom segment of the supporting rack in a set position of the bottom cross beam, then successively mounting the middle segments above the bottom segment successively according to the mounting height of the reversed stepped special-shaped steel structure, andfinally, mounting the top segment, wherein the bottom segment, the middle segments and the top segment are fixedly connected through bolts; 4) mounting the jack; 4) hoisting a first layer of the reversed stepped special-shaped steel structure; 6) detaching the supporting part; and 7) repeating the steps 2) to 6) till the whole reversed stepped special-shaped steel structure is mounted.

Description

technical field [0001] The invention relates to the technical field of building construction supplies, in particular to a construction method of an inverted ladder shaped special-shaped steel structure. Background technique [0002] With the development of our country's economy, the country pays more and more attention to the combination of spiritual culture and energy-saving and environmentally friendly buildings, and vigorously promotes steel structure buildings. With the advancement of science and technology, special-shaped steel structures can be implemented. This structure is not only beautiful but also symbolic. The significance of the city, and it is favored by more and more construction companies. [0003] At present, inverted ladder-shaped special-shaped steel structures are used in various large-scale theme parks, landmark buildings and other architectural structures. For example, in a large-scale theme park, the lower structure is a 3-story basement. Up to the 5t...

Problems solved by technology

[0003] At present, inverted ladder-shaped special-shaped steel structures are used in various large-scale theme parks, landmark buildings and other architectural structures. For example, in a large-scale theme park, the lower structure is a 3-story basement. Up to the 5th floor and above, an inverted ladder-shaped space steel structure is adopted, which has a peculiar shape and a complex structure. Each floor cantilever outwards around the perimeter, and the stability during installation is poor. When it is not formed as a whole, it needs to be supported by a temporary support frame.

[0004] However, since the vertical projection range of the inverted ladder-shaped space steel structure is within the scope of the basement, the requirements for support measures are higher. If the support is on the floor, the floor serves as the support surface and needs to bear the gravity of the steel structure on each floor. In this way, It is easy to cause damage to the floor
