Description

A kind of top is provided with cable curtain wall supporting system and the construction method thereof of steel truss
Technical field
The present invention relates to a kind of building guy cable Curtain Wall technical field, particularly relate to a kind of the cable curtain wall supporting system and the construction method thereof that are provided with steel truss for top.
Background technology
Cable curtain wall glass is suspended on the online curtain wall form of cable wire, this curtain wall span greatly, succinctly penetrating, there is strong times flavour, firmly get liking of numerous architects and the common people.In order to form a Zhongting opened wide, horizontal cable can be fixed on the column of building both sides by architect, vertical cable wire upper end is fixed on steel truss upper and lower end and is fixed on grade beam.The very large prestressing force of curtain wall wire rope needs applying could produce lateral stiffness and carry out supported glass curtain wall, and correspondingly, both sides building vertical column and steel truss just need the huge pulling force bearing very large cable wire generation.For this cable curtain wall steel truss of supporting, current susceptor design mainly contains two kinds of processing modes:
A kind of mode is slidably connected, and it is architectural that the one end by steel truss adopts the fixing hinged-support of three-dimensional, the other end adopts single-directional sliding support to be bearing in both sides respectively.This connected mode truss support when curtain wall vertical steel cable stretching prestressing force freely can rotate, not produce secondary stress to main body; But this connection belongs to Weak link, both sides building firmly cannot be coupled together, when horizontal cable stretch-draw prestressing force or earthquake, both sides building will produce moderate finite deformation.When cable curtain wall is very tall and big, this distortion will be very large, can produce very large internal force, curtain wall sometimes also can be caused to damage in both sides building, therefore this be slidably connected mode to agent structure and curtain wall all very unfavorable.
Another kind of mode is fixedly connected with, and the two ends of steel truss can all adopt the fixing ball hinged support of three-dimensional to build with both sides to be connected by it, and because bearing needs the vertical force of bearing and horizontal force all very greatly, ball hinged support is usually difficult to meet design requirement.Also there is designer directly by the slugging on the upper and lower string of steel truss and both sides building vertical column, utilize steel truss that both sides building is linked to be an entirety.This welding connecting mode structural integrity is fine, but truss support can not freely rotate when curtain wall vertical steel cable stretching prestressing force, builds produce very large secondary stress by making both sides, also very unfavorable to agent structure.
Summary of the invention
The invention provides cable curtain wall supporting system and construction method thereof that a kind of top is provided with steel truss, solve existing supporting cable curtain wall supporting system node structure complicated, the free to rotate and technical problem of the effect utilizing steel truss both sides building firmly to be connected when horizontal cable prestressed stretch-draw or earthquake of the bearing when vertical cable wire prestressed stretch-draw can not be met simultaneously.
For realizing above-mentioned technical purpose, the present invention adopts following technical scheme:
Top is provided with a cable curtain wall supporting system for steel truss, and the curtain wall wire rope of described cable curtain wall comprises vertical cable wire and horizontal cable, it is characterized in that, comprises following components:
Major structure of construction, is positioned at the cable curtain wall left and right sides, provides the drawknot fixed point of horizontal cable left and right sides;
Lower support structure, is positioned at the bottom of cable curtain wall, provides the fixed point of the drawknot bottom vertical cable wire;
Steel truss, described steel truss frame is in the upper end of the major structure of construction of both sides, and by winding up, lower edge, intermediate web elements and end web member form, and provides the hanging fixed point at vertical cable wire top; Adopt two-way reinforcement connected mode between the end of described steel truss and major structure of construction, comprise lateral connection and be vertically connected, described vertical connection is realized by the vertical load bearing be located between steel truss and major structure of construction top; Described lateral connection is realized by the horizontal load bearing be located between steel truss and major structure of construction side; Described lateral connection realizes by being located at horizontal load bearing between steel truss and major structure of construction side, that just carry out installing after the vertical cable wire of curtain wall carries out prestressed stretch-draw.
As preferred technical scheme, have a rectangular indentation adapted in major structure of construction, size and supporting part agent structure for frame in two lower corner of described steel truss, described vertical load bearing is arranged on the end node or hold between web member of winding up at major structure of construction end face and rectangular indentation top; Described horizontal load bearing is arranged between the lower edge of major structure of construction side and rectangular indentation side.
Further, in two that lay respectively at steel truss two ends vertical load bearings, one of them is three-dimensional fixed ball hinged support, and another is the one-way slide type ball hinged support along the unidirectional slip of steel truss prolonging direction.
Further, described horizontal load bearing is horizontal steel plate group, and described horizontal steel plate group comprises 1 ~ 4 piece of horizontal steel plate of setting parallel to each other, and the two ends, left and right of horizontal steel plate are fixed with the welding edges of major structure of construction sidewall and lower edge respectively.
Further, the rod member of described steel truss can adopt H profile steel, round steel pipe or rectangular steel pipe, and steel truss can be monolithic truss, triangular form space truss or rectangle space truss.
Further, the frame construction that described major structure of construction is made up of frame column and Vierendeel girder, frame support structure or shear wall structure, described steel truss frame is on the frame column of both sides major structure of construction.
Further, described frame column is concrete column, and capital built-in fitting is established at its top, and sidewall establishes post side built-in fitting, and described capital built-in fitting is connected with the bottom welding of vertical load bearing, being welded to connect of described post side built-in fitting and horizontal load bearing.
Further, described lower support structure is reinforced concrete wall or reinforced concrete beam.
Further, described lower edge, horizontal load bearing and the level of Vierendeel girder three is corresponding to axis overlaps.
In addition, the construction method of the cable curtain wall supporting system that the present invention also provides above-mentioned top to be provided with steel truss, is characterized in that: comprise the steps:
Step one, material prepare: the material comprising curtain wall inhaul cable, vertical load bearing and horizontal load bearing prepares or makes;
The preparatory processing of step 2, steel truss: according to design size, open a rectangular indentation adapted in major structure of construction, size and supporting part agent structure for frame respectively by two of steel truss lower corner;
The lifting of step 3, steel truss: after the construction of upper end major structure of construction, by steel truss lifting to major structure of construction top, both sides, according to gap portions locating rack on the frame column of the major structure of construction of both sides;
Step 4, vertical load bearing is installed: the vertical bottom of load bearing is welded with the capital built-in fitting at frame column top, the end node or hold web member to be welded and fixed of winding up at the top of vertical load bearing and rectangular indentation top;
