Problems solved by technology

This installation method is cumbersome, slow, labor-intensive, and dangerous, and it is not easy to control the accuracy of the installation, and at the same time delays the progress of the project; and because of the heavy restraint support, it will also affect the pre-tightening during the stand-alone installation process.

Embodiment Construction

[0012] Referring to the attached figure, a hoisting and installation method of the buckling restraint support, the buckling restraint support 1 is hoisted first, the lifting lugs 4 on both sides of the buckling restraint support 1 should be left in advance, and two on each side, when hoisted until the installation When entering the floor, the rope tied in advance on the support is pulled into the floor. When the buckling restraint support 1 enters the floor, a round steel pipe needs to be prepared under it, and then a hydraulic forklift is used to move it to the place to be installed. , the hand-push hydraulic forklift will put it into the center of the buckling-restrained support. At this time, the electric hoist on the beam is used to lift the buckling-restrained support and connect it with the embedded components on the beam and column. Finally, the cover plate is bolted to connect the After the installation of the buckling restraint support is completed, the gusset plate 2 ...

Abstract

The invention discloses a lifting and installation method of buckling restrained braces. The method provided by the invention is characterized in that the buckling restrained braces are lifted at first; when being lifted on a to-be-installed storey, the buckling restrained braces are pulled into a floor by using a rope tied on the braces in advance; next, the buckling restrained braces are moved to a to-be-installed location by using a hand-push hydraulic forklift; at the moment, the buckling restrained braces are lifted up by using electric hoists on a beam for butt joint with pre-buried components in the beam and columns; finally, cover plates are added and are connected by bolts to complete the installation of the buckling restrained braces. According to the lifting and installation method, the lifting and installation process is convenient and rapid; therefore the project progress is accelerated; the work period is shortened; the labor intensity is lowered; the on-site installation efficiency of the buckling restrained braces is improved greatly.

Description

technical field [0001] The invention relates to the technical field of building construction, and belongs to a hoisting and installation method of a buckling constraint support. Background technique [0002] When hoisting the constrained support, after hoisting to the floor to be installed, first unload the constrained support on the floor, and then transport the support horizontally to the place to be installed. After the point is near, the position of the support can be adjusted by adjusting the installation angle through the expansion and contraction of the pulley in the sling, and then the lower end of the buckling restraint support can be placed in place by pulling the lower end of the support to the installation position through the rope. The upper end of the support can be temporarily placed in place by pre-setting temporary supports or brackets. If the support is heavy, the upper end may not be decoupled until the support is installed. This installation method is cu...
