Construction method of hanging steel structure daylighting skylight

Abstract

The invention discloses a construction method of a suspension type steel-structured lighting skylight. The construction method comprises the following steps: (1) assembling a lighting skylight steel structure, wherein the lighting skylight steel structure comprises a steel-structured net frame and a pre-stress truss supported on the lower surface of the steel-structured net frame; (2) carrying out first time of pre-stress tensioning on a pre-stress inhaul cable of the pre-stress truss; (3) hoisting the whole body of the lighting skylight steel structure to a pre-set height and suspending the lighting skylight steel structure on a supporting structure; (4) tensioning the a pre-stress inhaul cable of the pre-stress truss to a designed value. The steel-structured net frame is assembled module by module through adopting a horizontal slippage and jacking manner, the problem that the steel-structured net frame has relatively great weight and cannot be wholly hoisted can be avoided. By adopting a modularized assembling method, construction procedures also can be arranged by adopting a flow line manner, so that the construction time is saved. Each strip-shaped unit is assembled on the surface of a fifth floor, so that the construction engineering quantity of a supporting system and an operation platform is obviously reduced.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a construction method for a hanging steel structure daylighting skylight. Background technique [0002] Due to their own building function requirements, large-scale public buildings and large-scale complex buildings generally have relatively large single-floor areas and relatively high floor heights. One or several atriums with lighting function are designed in the middle of the building to provide enough light for the building. This type of daylighting atrium roof skylight adopts a steel structure to bear the force, and the top is a curtain wall glass panel, which not only has the effect of daylighting, but also has the effect of heat preservation and energy saving. [0003] This type of skylight has the following characteristics: 1. The supporting structure of the skylight is the main structure around the atrium; 2. The atrium is directly below the skylight, and the distance...

Problems solved by technology

[0003] This type of skylight has the following characteristics: 1. The supporting structure of the skylight is the main structure around the atrium; 2. The atrium is directly below the skylight, and the distance between it and the structural floor directly below is relatively large. 3. It is impossible to arrange tower cranes for skylights alone during construction of such large-volume buildings, and it is difficult for vertical lifting equipment such as truck cranes to cover them completely; 4. When installing skylights, the surrounding main structures have already been constructed Completion, also affects the arrangement of vertical lifting equipment
