Definitions
- the invention concerns a safety apparatus for carrying out work on the roofs of buildings, that is, a set of safety elements to prevent operators who are working at a considerable height off the ground from falling, for example, when putting up the roofs of residential, or industrial buildings in general, when installing, or repairing, television aerials, telephone or electrical cables, when working on walls, or painting, and any other such operation.
- Prior art comprises extendible ladders mounted on lorries, with, at their free end, a basket for carrying in it at least one operator and some equipment required for carrying out zu particular type of job.
- scaffolding is put up, possibly having working platforms that may be elevated, equipped with safety railings to enable work to be carried out at different heights on the wall and up to the roof of the building.
- ladders and scaffolds it is not possible to carry out work on areas of the roof that are distant from its edge, that is, they do not permit access to the innermost parts of the roof, and as a result, operators are poorly protected, or completely unprotected, when they are required to work in these areas; this represents a source of serious personal danger, as well as being an onerous responsibility for the commissioning agent.
- the invention resolves said technical problem by adopting a safety apparatus having at least one safety unit comprising means for fixing one of the ends of a safety cable having an other end which may be securely attached to the operator.
- Such an apparatus however has to be necessarily fixed onto the ridge of a roof and it is not adapted to be fixed, for example, on a pitched surface or on a vertical one.
- the invention provides a safety apparatus suitable for fixing to any off-ground surface and that has the features set forth in Claim 1.
- Each safety unit has a base structure which is securely anchored to the roof.
- the various safety units are preferably distributed over the roof in such a way that the entire surface is made accessible and, furthermore, they are interconnected with each other with lengths of cable stretching from one unit to the next and/or previous one.
- At least one of said safety units is located at a preferred access route to the roof, for example, in proximity to a skylight, a gutter, or other suitable structural element.
- a safety unit comprising a base structure that may be anchored to the upper surface of the roof and post means having a lower end which may be anchored to said base and an upper end coupled to means for supporting the end of a safety cable having its other end attached to the operator.
- said means of support is rotationally coupled to the end of the post means.
- said means of support consists of a revolving sleeve rotationally coupled to the upper end of said post, from which protrude an upper shelf whose free end is angled slightly downwards and has means for hooking on to a body of a safety cable reel, and a lower shelf having a fork-shaped free end angled slightly upwards to stabilise the position of said reel body.
- said base structure comprises an anchoring plate for fixing it to the surface of the roof by means of anchoring devices, said plate being coupled to the lower end of said post by means of a joint that may be locked in predetermined angular positions.
- said joint consists of a vertical plate projecting from said anchoring plate in a median zone of it, having a pin for hinging the lower end of said post and a set of holes distributed along at least one row having a curved path for the insertion, in one of the holes, of a locking bolt.
- a safety apparatus comprises a plurality of safety units 1 uniformly distributed over the surface 2 of the roof 3, that is, in such a way that an operator P is able to reach every zone of the surface 2 to carry out the required operations on it, whilst remaining permanently attached to said safety apparatus: to this end, the safety units 1 may be distributed in line every 10 - 20 m along the apex of an inclined roof 3.
- the safety units 1 are interconnected by lengths of cable 4 by means of fixed means of tightening 13a, or adjustable 13, in such a way that, when an operator finishes operating in a zone Z that lies within the operating range L and has to therefore move in order to hook the reel 5 of the safety cable 6 at another safety unit 1, the operator may remain anchored to the cable 4 by means of a relative spring catch and a short safety rope not shown, thereby maintaining the condition of maximum safety for the operator even when moving between the unit 1 and the next unit.
- the safety apparatus has preferential positions for climbing up and/or down, that may consist of skylights 7 of branches S ( Figures 1, 3) of the apparatus that extend to an area of the edge of the roof in proximity to the eaves, or gutters.
- each safety unit 1 may comprise a post 10, advantageously consisting of a tubular element, having a base 15 provided with a plate 16 anchored to the upper surface 2 of the roof 3; the upper end of the post 10 supports in a pivotable manner a sleeve 9, which is kept in a predetermined axial position by means of a safety ring 27, acting also as a means for anchoring the means 13, 13a for tightening the cable 4 and by a transverse upper bolt 26.
- an upper shelf 8 Projecting from the external surface of the sleeve 9 there are an upper shelf 8, having a free end folded downwards to couple with a spring catch 7a on the rear of the body of the reel 5 for the safety cable 6, and a lower shelf 11 having a fork-shaped end 12 pointing upwards, around a front portion of the lower part of the body 5 of said reel, allowing the safety cable to run freely and stabilising the position of said reel.
- the base structure 15 comprises a base plate 16, anchored to the surface 2 by means of means for anchoring comprising a counter plate 17 fixed to a load bearing beam 14 of the roof by means of tie bolts 18, and a vertical plate 19 projecting from the median area of said base plate and strengthened by ribs 23.
- the lower end 20 of the post 10 is formed by a pair of elements having U-shaped sections positioned opposite each other and associated with a plate of the lower end of said post.
- the safety units 1 making up the safety apparatus may be lowered, when operators are not required to go onto roof, by simply removing the bolt 22 and rotating the posts 10 around their respective hinges 21: this, in order not to alter the architectural harmony of the building.
