Problems solved by technology

Due to the effect of the building facade, the design requires the steel structure beams of the roof to be heavy-duty steel beams, and the shape is particularly complicated, which brings great difficulties to the construction
Traditional construction methods cannot meet the design requirements, and new technical means are needed to solve the problems faced

Embodiment Construction

[0025] The technological principle of the present invention is that the steel girder components are assembled and welded at effective positions, and the supporting frame is removed after each steel girder is formed to slide to the designed position.

[0026] The basic structure of steel beams is

[0027] 1. Pre-embed the steel plate for fixing the slideway according to the position of the roof steel beam. The thickness of the steel plate is t=8mm and the width b=400mm.

[0028] 2. According to the height, shape and width of the special-shaped steel beams on the roof, bowl-shaped steel pipes are used to build the support frame to meet the pressure and safety requirements, and pass the professional inspection. When assembling the steel girders according to the shape of each girder, the maximum hoisting weight of the tower crane is 5.5 tons, and each girder needs to be hoisted 21 times. Designed as a secondary weld, 20% flaw detection. After qualified, the rust removal and fini...

Abstract

The invention discloses a method for glidingly constructing a large-span special-shaped heavy steel girder on a super high-rise roof. The method comprises the following steps of mounting a slide way pre-buried component; lifting a frame body by a tower crane; erecting a supporting frame body; assembling the steel girder section by section; welding a two-roof truss connecting rod; detaching a girder bottom support and a jig frame; mounting a slide way and a propeller; mounting a hydraulic control system; debugging a propeller control system; glidingly moving the steel girder to a designed position; correcting the position of the steel girder; welding supporting feet to the two sides of the steel girder; glidingly moving the third steel girder according to the above steps; detaching the slide way and a propeller system; detaching a steel girder supporting frame body. The method has the beneficial effects that due to the adoption of the construction technology that steel structures are lifted to a roof section by section by the tower crane, the steel girder is welded and assembled on the roof, and the whole steel girder is glidingly moved, the problem that a large component cannot be lifted by the tower crane at high altitude is solved.

Description

technical field [0001] The invention relates to a sliding construction method of a large-span abnormal-shaped heavy-duty steel beam on a super-high-rise roof, and belongs to the technical field of building construction. Background technique [0002] With the development of the national economy and the continuous improvement of people's living standards, the works of architects are becoming more and more colorful and full of personality, especially the unique appearance and top design of the roof. The architectural design of this project is the American NBBJ design firm, and the appearance is 5 large ships set sail by Yang Fan. Due to the effect of the building facade, the design requires that the steel structure beams of the roof be heavy-duty steel beams, and the shape is particularly complicated, which brings great difficulties to the construction. Traditional construction methods cannot meet the design requirements, and new technical means need to be sought to solve ...
