Embodiment

[0027] Embodiment: As shown in the figure, a method for installing an outer frame cylinder structure of oblique steel pipe grid columns includes the following steps:

[0028] Step 1: Position the supporting steel pipe 8 on the base 4, and complete the welding and fixing process of the supporting steel pipe 8 and the base 4 according to the installation slope and span of the grid column 3.

[0029] The second step: then adjust the angle inclination of the sling 1 through the chain hoist 2 to align the hoisting process of the grid column 3 . The length of the sling 1 , the position of the hanging point and the angle are determined by the installation length, angle and center of gravity position of the grid post 3 . The connecting length between the sling 1 and the lower part of the grid column 3 is 12 meters, and the connecting length between the sling 1 and the upper part of the grid column 3 is 7 meters.

[0030] Step 3: After the grid column 3 is aligned with the supporting ...

Abstract

The invention relates to an installation method for an oblique crossing steel pipe and grid column type outer frame barrel body structure, and belongs to the technical field of building steel structure construction. The installation method comprises the following operation steps that a supporting steel pipe is positioned on a base, and the welding and fixing process of the supporting steel pipe and the base is completed according to the installation inclination and span of a grid column; then the angle inclination of a sling is adjusted through a chain block to align the hoisting process of the grid column; then a pair of symmetrically distributed grid columns and the supporting steel pipes are temporarily fixed through a plurality of butt joint lug plates which are annularly distributed at equal intervals; then operation platforms are installed on the pair of grid columns, and then oblique crossing steel pipes are hoisted to be aligned with the upper ends of the grid columns; and after the oblique crossing steel pipe and grid column type outer frame barrel body structure forms a stable A-shaped structure system, welding work is carried out. The method has the advantages of high construction safety and reliability, simple construction method and short construction period. The inclination angles and the axis positions of the oblique crossing steel pipes and the grid columns areguaranteed, shaking is effectively reduced, and the hoisting accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of building steel structure construction, in particular to a method for installing an outer frame cylinder structure of oblique steel pipe grid columns. Background technique [0002] With the development and prosperity of today's social economy and the rapid development of the construction industry, modern buildings have higher and higher requirements for structural height and shape, which has prompted the emergence of some new architectural structural systems. The oblique lattice column structure is a new type of high-rise and super high-rise structural system. It has strong lateral rigidity and flexible plane shape layout, and can realize various beautiful shapes with high efficiency, which meets the needs of modern buildings. Pursuing the dual needs of height and beauty, it is widely used in the construction of modern high-rise and super high-rise buildings. [0003] The outer frame cylinder structure of...
