A Construction Method for Super-Large Span Escalator Steel Box Girder Support

Abstract

The invention discloses a super-large-span escalator steel box girder support construction method, including construction BIM deepening, construction plan determination, split component processing, construction preparation, component entry, "small waist" installation, escalator box girder support installation and acceptance. The beneficial effect of the present invention is: use BIM technology to carry out three-dimensional simulation installation for installation and construction, find out the difficult points of quality control, ensure the quality of joint construction, use the crane to hoist in sections, avoid setting up tall operation frames, and greatly reduce the cost of turnover materials Using and labor consumption saves construction cost, the construction work is relatively concentrated, and there are few potential safety hazards, which is convenient for centralized management on site. The factory mechanized segmental processing reduces the amount of welding on site, avoids waste, light pollution, etc., and uses BIM technology to simulate installation , prevent technical and quality problems in advance, and reduce on-site problems.

Description

technical field [0001] The invention relates to a support construction method, in particular to a super-large-span escalator steel box girder support construction method, which belongs to the technical field of construction. Background technique [0002] In order to achieve better spatial effects, large-scale businesses generally set up atriums in commercial buildings, and setting escalators in the atriums to broaden the view and evacuate the flow of people is also a common practice in most commercial complexes. Shopping malls with super-high escalators are very rare. The use of long-span escalators can occupy as little space as possible under the escalator, and strive to make the structure of the escalator novel and people's visual experience different. In order to achieve this effect, the atrium of the commercial complex uses The steel girder box supported on the structure by the supports at both ends is used as the support system of the escalator and its skeleton, support...

AI Technical Summary

Problems solved by technology

[0003] Although the current ultra-large-span escalator steel box girder support construction method is widely used, it still has some problems. First, the existing super-large-span escalator steel box girder support construction method has high manufacturing costs and low safety factor. 2. The existing ultra-large-span escalator steel box girder support construction method is inconvenient to control the construction quality and has a long construction period
