[0001] The invention relates to the technical field of building construction, and in particular to an adjustable multi-point anti-falling device assembled on a building outer wall and a use method thereof. Background Art

[0002] At present, building components refer to the various elements that make up a building. If a building is regarded as a product, then building components refer to the parts of this product. The components in a building mainly include: floors (roofs), walls, columns, foundations, etc., which are not exactly the same as the concept of structural components. Structural components are the elements that constitute the structural force skeleton, of course, also include beams, slabs, walls, columns, foundations, etc., but it is generally divided according to the force characteristics of the components, and is divided into bending components, compression components, tension components, torsion components, and compression-bending components.

[0003] When using the existing anti-fall device of building components, it is necessary to first drill holes in the building wall and drive fixing bolts into the holes, and then fix the anti-fall device to the user and the fixing bolts respectively, so as to prevent workers from slipping and falling. However, since the length of the connecting rope of the anti-fall device cannot be extended and the installation position of the fixing bolts is a fixed point, if it is necessary to move over a long distance, it is necessary to drill multiple holes in the wall and drive fixing bolts into the wall for workers to connect and use. This method not only causes excessive damage to the wall, but also reduces the workers' freedom after being connected to the building components through the anti-fall device. For this reason, we propose an anti-fall device for building components used in construction. Summary of the invention

By arranging the anti-falling steel rope to pass through the through hole on one side and then pass through the tightening through hole on the other side, and then holding the crank handle to rotate counterclockwise to drive the tightening wheel to rotate, the tightening through hole also rotates accordingly to drive the anti-falling steel rope to be wound around the surface of the tightening wheel, so that the too loose anti-falling steel rope is tightened. After being stretched, there will be a reverse force that drives the take-up wheel to reverse. At this time, the traction spring tightly pulls the check tooth to fit the surface of the ratchet. When the take-up wheel reverses, the check tooth will quickly engage and insert into the interior of the ratchet, and the ratchet is used to limit the take-up wheel to prevent the take-up wheel from reversing and causing the anti-fall steel rope to loosen. Since the movable slider is in an openable and closable state, the moving slider is connected to the anti-fall steel rope and then connected to the staff through the connecting buckle to complete the fall prevention work. This device is convenient for preventing workers from falling. BRIEF DESCRIPTION OF THE DRAWINGS
