Oversized plate rib-free full-glass curtain wall mounting construction method

Abstract

The invention discloses an oversized plate rib-free full-glass curtain wall mounting construction method. The oversized plate rib-free full-glass curtain wall mounting construction method is characterized by comprising the following steps that firstly, a glass dedicated lifting truss is designed and manufactured; secondly, a glass fixing device and a lifting hoist are mounted; thirdly, glass is bound on the lifting truss; fourthly, a crane is used for lifting the glass to the outer side of an overhanging eave of a building main body through the lifting truss; fifthly, a three-step method of first pushing, second pulling and third lifting is adopted for lifting the glass to the mounting fixing point; sixthly, external fixed angle iron is mounted; and seventhly, cleaning and acceptance checkare carried out. The lifting truss is simple in structure and achieves the supporting protecting effect on the glass, and lifting is convenient; the lifting manner of combining lifting of the liftingcrane with the three-step method of first pushing, second pulling and third lifting is adopted for solving the problems that the vertical mounting space is narrow, and under the condition that the external overhanging eave of the building main body exists, the crane cannot be used for carrying out direct in-place lifting; and the lifting structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the construction field of building curtain walls, in particular to a method for installing and constructing super-large plate ribless all-glass curtain walls. Background technique [0002] Glass curtain walls are generally divided into frame-supported glass curtain walls, point-supported glass curtain walls and all-glass curtain walls. The large-span ribless all-glass curtain wall has a simple structure and achieves a more transparent view. Space, complex installation structure and visual impact. As the design height of the ribless all-glass curtain wall continues to increase, some single-piece glass of the curtain wall has a size of 1.8mx12m and a weight of 4t, especially when constrained by the limited space of the main structure (such as the overhanging distance of the top structure of the installation area is relatively long) Long, etc.), it is difficult to vertically hoist the glass of the oversized and overweight plate i...

Problems solved by technology

[0002] Glass curtain walls are generally divided into frame-supported glass curtain walls, point-supported glass curtain walls and all-glass curtain walls. The large-span ribless all-glass curtain wall has a simple structure and achieves a more transparent view. Problems of complex space, installation structure and visual impact

As the design height of the ribless all-glass curtain wall continues to increase, some single-piece glass of the curtain wall has a size of 1.8mx12m and a weight of 4t, especially when constrained by the limited space of the main structure (such as the overhanging distance of the top structure of the installation area is relatively long) long, etc.), it is difficult to vertically hoist the glass in one oversized and overweight plate into place

If the existing electric multi-claw automatic pressurized glass suction cup is used to lift large plates of glass, it is necessary to customize a special multi-claw glass suction cup device according to the glass specifications of the construction site conditions. The cost of device customization and transportation is very high, and the steering performance of the device cannot meet the requirements. Installation Requirements in Space Constrained Situations
