Detailed Description

The present application is described in further detail below.

The embodiment of the application discloses safety device for high-rise building construction, refer to fig. 1, including scaffold 1, scaffold 1 upper berth is equipped with protection network 6, is provided with clamping jaw 3 between protection network 6 and the scaffold 1.

The scaffolding 1 comprises a ledger 12 and a standard 11 arranged perpendicular to each other. The cross rod 12 and the support rod 11 are fixedly connected through a fastener. The crossbars 12 are arranged in a plurality of staggered ways, the crossbars 12 are evenly distributed along the horizontal plane at intervals, and the crossbars 12 form the supporting surface of the scaffold 1. The supporting surface is provided with a protective net 6 above the cross bar 12. The protective net 6 is made of high-strength fiber materials such as nylon, vinylon, terylene and the like. The protection net 6 includes a plurality of meshes.

The adjusting sleeve 5 is sleeved on the support rod 11 above the cross rod 12. Referring to fig. 2, an adjusting bolt 51 is threadedly coupled to the adjusting sleeve 5. The adjusting bolt 51 passes through the adjusting sleeve 5 and abuts against the support rod 11. The adjusting sleeve 5 is fixedly connected with a fixed seat 2. The fixed seat 2 is positioned between the cross rod 12 and the adjusting sleeve 5. Fixing base 2 is the cubic of vertical setting, and the bottom of fixing base 2 is connected with clamping jaw 3. The clamping jaw 3 comprises a first gripping bar 31 and a second gripping bar 32, which are symmetrically arranged along the bottom edge of the fixing base 2. The top end of the first grabbing rod 31 is open, the opening is matched with the thickness of the fixed seat 2, and the first grabbing rod 31 is connected with the fixed seat 2 in a sliding mode along the length direction of the cross rod 12 through the opening. The structure of the second grab bar 32 corresponds to the structure of the first grab bar 31.

A nip 33 is formed between the first and second

gripping bars

31 and 32. The ends of the first grabbing rod 31 and the second grabbing rod 32, which are far away from the fixed seat 2, are both inserted into meshes of the protection net 6 downwards, and are arranged in a bending manner towards one side close to the clamping opening 33. The sides of the first and second grab bars 31 and 32 near the nip 33 are both fixed with protruding gripping teeth 34 to increase the contact area of the nip 33 and the protection net 6.

One side of the fixed seat 2 is provided with a rotating rod 4. One end of the rotating rod 4 is movably connected with a first crank 41. The first crank 41 and the rotating rod 4 are of an integral structure, and one end of the first crank 41, which is far away from the rotating rod 4, extends towards one side close to the clamping opening 33 and is hinged with the first grabbing rod 31. The hinge axis is parallel to the length direction of the crossbar 12. The end of the rotating rod 4 departing from the first crank 41 is movably connected with a second crank 42.
