Abstract
The invention discloses a method for measuring, positioning and installing a triangular system inclined steel column. The triangular system inclined steel column comprises a first steel casting, a second steel casting, a third steel casting, outer frame columns and a box-type steel girder. The installing method comprises the following specific steps: installing the second steel casting and the third steel casting first; then hoisting the box-type steel girder; next, installing the outer frame columns; and finally, hoisting the first steel casting to the top of the outer frame columns, positioning and welding the first steel casting, thus completing the installation. The method realizes quick installation of the triangular system inclined steel column on site, so that the main body shape of a building can be realized.
Description
Technical field
The present invention relates to a kind of mounting method of steel column, specifically a kind of super large triangular system inclination steel column measurement and positioning mounting method.
Background technology
The new Building Project of Hangzhou branch of China Citic Bank is positioned at new city A-08-6 plot, Qianjiang, Hangzhou, Zhejiang province city, and it is designed by world-renowned FOSTER, overall floorage 5.9 ten thousand square metres, building height 99.9 meters.Totally three layers, this engineering underground, be 20 layers on the ground, building main body is the huge support steel structure system of urceolus inside casing, adopts the multiaspect corner cut having imagination, reflects shadow change, exactly like a golden diamond by curtain wall.Building main body changes in multiaspect corner cut in seven layers of place's closing waist, the positive facade in building is isoceles triangle structural system below seven layers, system top node is up to 30 meters, and in 40 ° of inclinations, realize the triangular system of above-mentioned moulding, need the triangular system inclination steel column designing commensurate structure, and complete installation.
Summary of the invention
Goal of the invention: the invention provides a kind of triangular system inclination steel column structure and realize building overall shape, and the measurement and positioning completing this triangular system inclination steel column is installed.
Technical scheme: a kind of triangular system inclination steel column measurement and positioning mounting method, described triangular system inclination steel column comprises: the first steel-casting, the second steel-casting, the 3rd steel-casting, exterior frame column and steel beam with box shape;
Described triangular system inclination steel column is isosceles triangle; Described first steel-casting, the second steel-casting, the 3rd steel-casting are positioned at the summit of isosceles triangle, and described exterior frame column is the waist of isosceles triangle; Described steel beam with box shape is the base of isosceles triangle; Described triangle inclination steel column becomes 40 ° and tilts with vertical direction;
The concrete steps of described triangular system inclination steel column measurement and positioning mounting method are as follows:
(A) by the mode of " lifting+slippage ", the second steel-casting, the 3rd steel-casting are installed;
(B) steel beam with box shape is lifted; In advance arch camber is carried out to steel beam with box shape; This steel beam with box shape is reasonably divided into 6 segmentations, each segmentation weight demands is less than 25 tons, and each girder steel segmentation is all installed it by arranging temporary support;
(C) exterior frame column is installed; In housing column bottom, corresponding steel pipe support position is welded a H type and is assisted bracket in advance, places a jack between auxiliary bracket and steel pipe support, is mainly used in the fine setting of exterior frame column location.After three-legged structure system has unloaded, auxiliary bracket is cut off;
(D) by the top positioning welding of the upper exterior frame column of the first steel-casting lifting.
Beneficial effect: triangular system inclination steel column measurement and positioning mounting method provided by the invention, achieves the Fast Installation at triangular system inclination steel column scene, building overall shape is realized.
