Abstract
The invention discloses a movable safety net, which comprises main bearing ropes, pulling ropes, safety net structure ropes, a safety net body, guide pulleys, U-shaped fasteners, deflecting pulleys, hanging rings, U-shaped lugs, tiger clips and chain blocks. The specific technical solution of an installation method for the movable safety net is as follows: the hanging rings and the U-shaped lugs are mounted, the safety net is woven, the woven safety net is respectively connected with the main bearing ropes and the pulling ropes, and a 5T windlass or a truck crane is used for hoisting the safety net arranged on the main bearing ropes to get under column bottom beams. The movable safety net and the installation method thereof provided by the invention decrease the installation and dismantling risk of safety nets, prevent the high-altitude dropping of workers tying or dismantling the safety net in high altitude, decrease difficulty in the process of hanging the safety net and hoisting a structure, and also relatively reduce the investment of cost such as manpower cost, machine cost and material cost.
Description
Technical field
The invention belongs to metallurgy steel structure high-altitude working safety net protection field, particularly a kind of moving type security net and mounting method thereof, be applicable to the installation of steel structure high-altitude operation.
Background technology
In existing metallurgy steel structure installment construction; often work high above the ground can be run into; falling from high altitude is one of common several major injuries; specify according to " building operations high-rise working technical specification of security " JGJ 80-1991: during high-rise working, must safety net be set up; so aloft operation time safety net can prevent high falling; ensure operating personnel's life security, therefore installing and using of safety net seems particularly important.Traditional safety net installation and application be woven safety net system could have been hung over after roof girder has installed two across between roof girder backspin, by that analogy.There is following shortcoming in the method that this mode hangs safety net:
1, safety net hangs at roof girder backspin that mooring points is a lot, linked network personnel live forever in the potential safety hazard of falling from high altitude at roof girder backspin travel time; Lift when Roof system (support of linking beam, coupling, purlin) 2, is installed and have difficulties; 3, from installation process, the linked network time is long, employment is many, length consuming time, mechanical one-shift are many, linked network cost is higher; 4, after Roof system installation terminates, safety net is in unloading process, and dismounting personnel must run to each binding Nodes dismounting of safety net by fine jade under the roof girder of high-altitude, and work high above the ground is consuming time longer, there is security risk higher.
Summary of the invention
