A construction method of an inverted stepped special-shaped steel structure

Abstract

The invention discloses a construction method for an inverted ladder-shaped special-shaped steel structure, which includes the following steps: 1) Preparing supporting parts: the supporting parts include jacks, bottom beams and support frames; wherein, the bottom beams include two The beam body, the support frame includes a bottom segment, a top segment and several middle segments; 2) Install the bottom beam on the lower building; 3) Install the support frame: install the bottom of the support frame at the set position of the bottom beam section, and then according to the installation height of the inverted ladder-shaped special-shaped steel structure, several middle sections are successively installed above the bottom section, and finally the top section is installed, wherein the bottom section, the middle section and the top section pass through Bolt fixed connection; 4) Install the jack; 5) Hoist the first layer of the inverted stepped special-shaped steel structure; 6) Remove the supporting parts; 7) Repeat steps 2)-6) until the installation of the entire inverted stepped special-shaped steel structure is completed .

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
