Description

Rotatable anti-falling anchor structure for wood roof

Technical Field

The utility model relates to a safety protection field especially relates to a rotatable anti-falling anchor structure of wooden roofing.

Background

The wooden roof structure is the sloping roof usually, and when construction and later stage maintenance, the workman often relies on experience to carry out the operation at this kind of roofing that has the slope, and does not have any safeguard measure, and this has increased the probability that the injury that falls relevant even death accident takes place undoubtedly, and does not conform to the relevant regulation of safe construction at present.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to prior art's defect and not enough, provide a rotatable anti-falling anchor structure of wooden roofing, through safety rope or safety belt during the workman's operation with prevent that the D type ring that weighs down the anchor subassembly is connected to security when having guaranteed the workman's operation has reduced the probability that the accident that falls takes place.

In order to achieve the above object, the utility model adopts the following technical scheme: a rotatable anti-falling anchor structure for a wooden roof comprises an anti-falling anchor assembly, the wooden roof and a bolt; the anti-falling anchor assembly is fixed on the wooden roof through a bolt; the anti-falling anchor assembly comprises an anchor cover, a base plate, a rotary anchor and a D-shaped ring; the bolt sequentially penetrates through the anchor cover and the base plate from top to bottom; the anchor cover consists of a sealing cover and a fixed cylinder, and the outer end of the fixed cylinder is in a step shape so as to be jointed with the substrate; the anchor cover is also sleeved with a rotary anchor which can horizontally rotate along the outer wall of the fixed cylinder of the anchor cover; the rotary anchor is a cylinder, and a central hole is formed in the middle of the rotary anchor; the rotary anchor is provided with a pair of stepped holes which are gradually increased from inside to outside in a stepped manner; the D-shaped ring is clamped in the rotary anchor through a clamping head structure matched with the stepped hole, and the D-shaped ring can be turned over along a vertical plane.

Preferably, the bolts are provided through the wooden roof.

The utility model has the advantages that:

1. when workers work, the workers are connected with the D-shaped ring of the anti-falling anchor assembly through the safety rope or the safety belt, so that the safety of the workers during the work is ensured, and the probability of falling accidents is reduced;

the D-shaped ring can rotate along the horizontal plane and the vertical plane, so that the movable type roof covering operation is suitable for workers, and the winding phenomenon of a safety rope or a safety belt is avoided.
