Problems solved by technology

[0003] When the roof steel girder (H-shaped steel beam) of the steel structure is installed on site, because there are no other components above the roof, there is no firm place to hang the safety belt reliably. At this time, it is necessary to tension the safety rope to hang the safety belt. The traditional method is to directly weld the safety rope pillar on the steel beam, so that the safety rope pillar cannot be reused, and it is inconvenient to install and disassemble, and it is easy to cause damage to the main structure of the steel beam during disassembly

Embodiment approach

[0027] The specific embodiment, the inner side of the vertical bar of the clip 1 is respectively fixed with rubber pads 8, which are used to prevent the main body of the steel beam 1 from being damaged by the contact between the clip 2 and the upper flange of the steel beam 1 during the tightening of the fastening nut 4 .

[0028] Here the rubber pads are fixed on the inner sides of the corresponding vertical rods by adhesive. In this way, a rubber pad is provided at the contact between the clip and the upper flange of the steel beam, so when the nut is tightened, the clip will not directly contact the main body of the steel beam, so it will not cause damage to the main structure of the steel beam; at the same time, due to the rubber pad The setting of the block can make after the fastening nut is tightened, the clip and the upper flange of the steel beam are buckled more closely, so that the overall structural stability of the safety rope tensioning measure frame is better. ...

Abstract

The invention discloses a method for tensioning a safety rope on a steel beam. The method comprises the following steps that a plurality of safety rope tensioning points are arranged on an upper flange of the steel beam at certain intervals according to the hanging position of a safety belt and the length of a corresponding H-shaped steel beam; then, a detachable safety rope tensioning measure frame is arranged at each safety rope tensioning point; and finally, the safety rope is arranged on the safety rope tensioning measure frames in a tensioning mode, and therefore tensioning of the safety rope is completed. By means of the method, safety rope tensioning is more standardized and normalized, and a steel beam main body cannot be damaged.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a method for tensioning a safety rope on a steel beam. Background technique [0002] As one of the "three treasures" of building construction safety protection, the safety belt can effectively ensure the safety of workers working at heights. When the seat belt is in use, it must be hung on a firm place reliably. In places where the seat belt cannot be directly hung, safety ropes and safety railings for hanging the seat belt should be installed. [0003] When the roof steel girder (H-shaped steel beam) of the steel structure is installed on site, because there are no other components above the roof, there is no firm place to hang the safety belt reliably. At this time, it is necessary to tension the safety rope to hang the safety belt. The traditional method is to directly weld the safety rope prop on the steel beam, so that the safety rope prop cannot b...
