A cable curtain wall support system with a steel truss on the top and its construction method

Abstract

The invention provides a dragline curtain wall support system with a steel truss at the top and a construction method thereof. The dragline curtain wall support system comprises main building structures at two sides, a support structure at the lower part, the steel truss at the top and a curtain wall steel cable at the middle, wherein the main building structures provide left and right fixed points of the steel cable, and the steel truss and the support structure at the lower part provide upper and lower fixed points of the curtain wall steel cable; a two-direction fixed mode of horizontal connection and vertical connection is adopted at the two ends of the steel truss and between the main building structures; and the horizontal connection is realized through a horizontal bearing support, and the vertical connection is realized through a vertical bearing support. The dragline curtain wall support system is simple in structure and convenient in construction; by virtue of the two-direction support fixed mode, the structure strength is increased, the node structure is simplified, and the structure safety is greatly increased; The horizontal bearing support is installed after vertical steel cable prestress tension to enable the steel truss to freely rotate under the action of the vertical force, so that the secondary stress of buildings at two sides is reduced; and by transferring force by a horizontal steel plate, the bearing force is large, the stress is reliable, and micro-vertical deformation of the steel truss can also be applicable.

Description

technical field [0001] The invention relates to the technical field of a building cable curtain wall support system, in particular to a cable curtain wall support system with a steel truss on the top and a construction method thereof. Background technique [0002] The cable curtain wall is a form of curtain wall that hangs glass on the steel cable net. This kind of glass curtain wall has a large span, is simple and transparent, and has a strong flavor of the times, and is deeply loved by architects and the public. In order to form an open atrium, the architect can fix the horizontal steel cables to the columns on both sides of the building, fix the upper ends of the vertical steel cables to the steel trusses, and fix the lower ends to the ground beams. The steel cables of the curtain wall need to apply a large prestress to generate lateral stiffness to support the glass curtain wall. Correspondingly, the building columns and steel trusses on both sides need to bear the huge ...

Problems solved by technology

[0005] The invention provides a cable curtain wall support system with a steel truss on the top and a construction method thereof, which solves the problem that the existing supporting cable curtain wall support system has complex node structures and cannot meet the needs of the support when the vertical steel cables are prestressed. The technical problem of the effect of using steel trusses to firmly connect the buildings on both sides when the horizontal steel cables are prestressed and stretched freely or in an earthquake
