Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, in the method for tensioning the safety rope on the steel beam, a plurality of safety rope tensioning points are arranged on the upper flange of the steel beam at certain intervals according to the hanging position of the safety belt and the length of the corresponding H-shaped steel beam; then, each safety rope tensioning point is provided with a detachable safety rope tensioning measure frame; and finally, tensioning the safety rope on a safety rope tensioning measure frame so as to finish tensioning the safety rope.

The detachable safety rope tensioning measure frame is adopted to tension the safety rope, the main structure of the steel beam cannot be damaged, and the standardized tensioning of the safety rope in the building construction process is facilitated, so that standardized and standardized construction is realized.

In specific implementation, the safety rope tensioning measure frame comprises clamping pieces 2 and a pillar 6, the clamping pieces 2 are composed of two transverse rods horizontally arranged from top to bottom and a vertical rod vertically arranged, the vertical rod is arranged at the same end of the two transverse rods, and the two ends of the vertical rod are respectively connected with the corresponding ends of the two transverse rods, so that a U-shaped structure lying on side is formed, the clamping pieces 2 are provided with two notches of the two clamping pieces 2 which are oppositely arranged, so that two sides of the upper flange of the steel beam 1 are clamped in the two clamping pieces 2, the transverse rods above the two clamping pieces 2 are upwards turned for 90 degrees to form a connecting part, through holes are arranged on the connecting part, the free end of a screw rod 3 with a nut at one end part sequentially passes through the through holes on the two clamping pieces 2, a fastening nut 4 is sleeved at the free end of the screw rod 3 to connect the two clamping pieces 2, so that the two clamping pieces 2 are fixed on the upper flange of the steel beam 1, the pillar 6 is vertically upwards arranged on the transverse rod above one clamping piece 2, and the top of the pillar 6 is provided with a tensioning hole which is longitudinally arranged along the steel beam 1 and used for tensioning the safety rope.

Like this, two fastener lock tightly on the girder steel top flange to safety rope tension measure frame has just been fixed on the girder steel top flange, and the stretch-draw hole department winding of safety rope on the pillar is tied up tightly, and with the rope clip chucking, thereby fixes on safety rope tension measure frame, has just accomplished the stretch-draw of safety rope. Simultaneously, the safety rope tensioning measure frame can be used for tensioning the safety rope on steel beams with different specifications by selecting different screw lengths.
