Abstract
The invention relates to a hoisting and mounting method of a buckling restrained brace, which comprises the following steps: welding two lifting lugs at 1/3 transversely on each buckling restrained brace member; step two: installing a clamp, an electric hoist and a steel cable on a cross beam on which a buckling restrained brace member is to be installed; step three: the buckling restrained brace component is lifted to a position between steel columns close to the installation position by a tower crane, then the lifting hooks of two electric hoists on the beam are used for respectively hooking two lifting lugs corresponding to the buckling restrained brace component, two ropes are simultaneously adjusted after the lifting, the buckling restrained brace is slowly moved to the installation position, the lower end of the buckling restrained brace component is firstly pulled to reach a lower node position, then the upper end is in place and is in butt joint with the embedded parts of the beam and the column. According to the invention, the buckling restrained brace is hung between the steel columns by using the tower crane and then is pulled, installed and positioned by the electric hoist, so that the labor intensity is effectively reduced, the installation efficiency is improved, and the construction progress is accelerated.
Description
Technical Field
The invention relates to a hoisting and mounting method of a buckling restrained brace.
Background
The buckling restrained brace is usually installed by transporting the buckling restrained brace into the floor and then transporting the buckling restrained brace to the installation site by using a cart.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a hoisting and mounting method of a buckling restrained brace, solves the problems of slow progress and complicated procedure in the existing construction, reduces the labor intensity and improves the mounting efficiency.
In order to solve the technical problem, the invention is realized as follows:
a hoisting and mounting method of a buckling restrained brace is characterized by comprising the following steps:
the method comprises the following steps: welding two lifting lugs at 1/3 transversely on each buckling restrained brace member;
step two: installing a clamp, an electric hoist and a steel cable on a cross beam on which a buckling restrained brace member is to be installed;
step three: the buckling restrained brace component is lifted to a position between steel columns close to the installation position by a tower crane, then the lifting hooks of two electric hoists on the beam are used for respectively hooking two lifting lugs corresponding to the buckling restrained brace component, two ropes are simultaneously adjusted after the lifting, the buckling restrained brace is slowly moved to the installation position, the lower end of the buckling restrained brace component is firstly pulled to reach a lower node position, then the upper end is in place and is in butt joint with the embedded parts of the beam and the column.
The hoisting and mounting method of the buckling restrained brace is characterized in that: the mounting fixture comprises two semicircles with openings, the lower ends of the two semicircles are coaxially arranged and are connected with the electric hoist through lifting lugs, and the sizes of the openings correspond to the widths of the two sides of the steel beam.
The invention has the beneficial effects that: the complicated step that the buckling restrained brace is firstly hoisted into a floor and then is transported to the installation position in the traditional method is omitted, the labor intensity is reduced, and the installation efficiency is improved.
The temporary fixing clamp used for installing the electric hoist and fixed on the steel beam is simple in structure and can be repeatedly used.
The problems that the progress is slow, the construction can be completed by the cooperation of multiple persons, the waste of manpower and material resources is caused, and the engineering cost is high in the existing construction are solved.
