Description

TITLE

Anchoring device to irregular bodies.

TECHNICAL FIELD.

The object of the present invention, as expressed in the statement of this specification, refers to an anchoring device for irregular bodies, of the type used in performing vertical works.

BACKGROUND OF THE INVENTION

Normally, they are understood as vertical works, those that are carried out on facades of buildings or monuments, walls, walls or any other vertical arrangement, in general of great height, consisting of activities related to the construction, embellishment, painting, cleaning, restoration, etc., of said vertical arrangements.

Traditionally, so that operators can access their workplace in a facade or similar and, subsequently, develop their activity comfortably and safely, the previous placement of a scaffolding is required, from the base of the facade.

A scaffolding installation has several drawbacks; the first is that a scaffold requires firm support on a solid and preferably horizontal base, and this is not always possible, since the ground may be inconsistent and / or have unevenness; secondly, a scaffold is usually a large infrastructure, with all the inconvenience that this entails, such as transport, assembly and subsequent disassembly; Another drawback consists in the fact that, if the facade or wall is not completely vertical but inclined, the installation of scaffolding is more complex than usual; In addition, if the scaffolding is to be installed on the public highway, it has two additional drawbacks: that it bothers the passers-by and that, therefore, requires the request for permits

SUBSTITUTE SHEET (RULE 26) special (to the competent authorities) for that reason.

An alternative to the installation of scaffolding, consists in the use of a lifting platform, provided with a railing as a safety measure, whose lifting element has an extensible scissor structure (such as a pantograph or similar) and is preferably motorized from the ground; This method also requires access from the public highway, with the inconvenience that this entails, already mentioned.

Another alternative to the installation of scaffolding, increasingly used, consists in the lifting of the operators from the upper part of the facade; To do this, you can basically use two methods; The first consists of the use of at least two anchors installed in the upper part of the upper wall or wall of the facade, of which a horizontal platform with a railing is hung on which the operators are located, since said platform has of manual or motorized methods to move vertically at will, at the top of the facade; The second method consists in the use of personal anchoring devices, also installed in the upper part of the wall or facade, to allow each operator to be able to detach independently, directly from the upper part of it, through the use of harnesses and other complementary devices, similar in some cases to those used in climbing or caving.

In the case of using the personal anchoring method, there are basically three different device types designed for that purpose.

The first and most widely used today is based on the previous installation, in the upper part of the building, of some anchoring device of the so-called "chemical anchoring"; This type of anchor is basically composed of a eye bolt (eyelet with stud) and a two component glue; for its use, a hole must be previously made in some structural element of the building, in which the glue is poured; then the asparagus is introduced in the hole, leaving the ring out of it; Finally, when the glue has set and fixed the stud, the ring can already be used as an anchoring element for laying, progression lines or lifelines.

The second type of personal anchoring devices is based on the previous installation, in the upper part of the building, of some anchoring device such as a "sergeant" or "jaw" type "Captain" (such as those used in carpentry and related works , but in general, of greater size), adaptable to elements such as walls or slabs of which are located in the upper part of a facade, such that said device presents, in its front or anterior area, some ring or similar , from which a static progression rope is hung (also called "lifeline") whose purpose will be to offer the operator a grip element through which he can progress vertically and safely, both upward and downward; normally, an anchoring device of these characteristics also has a second ring or similar, in its rear area, which will serve to secure the anchoring device (by means of a safety rope or safety "forwarding line", linked thereto) to any other structural element of the building, such as a column, a chimney, etc .; This safety rope has the objective that in case the wall or fixing element to which the device is anchored is broken, said device does not fall outside the facade by dragging the operator with it.

The third type of personal anchoring devices is that specially designed for its attachment to protruding fasteners of the building structure, such as beams or the like; devices of this type can be either a "sergeant" or "gag" of small size fixed to a beam or the like, or a webbing or rope placed around said beam and properly knotted, or the like; these also have a "lifeline" and a "forwarding line", linked to the rings corresponding.

Naturally, the activity of the vertical worker will be aided by other complementary elements essential for vertical work, such as work harnesses, auxiliary dynamic ropes with anchor carabiners, rope blocking systems, "fall arrest" or "retractable lifelines", etc. .

The personal anchoring devices mentioned above have some drawbacks.

The "chemical anchoring" devices are safe but impractical, since they are not recoverable and, in addition, they deteriorate the element of the building structure in which the fixing hole has been made.

Traditional rigid anchoring devices such as the "sergeant" or the "jaw" have the disadvantage that they can only be fixed to rectangular morphology building elements such as walls or beams, but they cannot be fixed to other round morphology building elements, or asymmetrical, or other aspects such as, for example, a railing.

On the other hand, traditional flexible anchoring devices such as a webbing, a belt or a rope, can be adapted to non-rectangular morphology fixing elements but are not fixedly fixed to them, since when subjected to possible lateral tractions, they could slide and slide laterally over the chosen beam or fixing element; on the other hand, rings or rings must be incorporated into the belt or rope (one for the "life line" of progression and the other for the "forwarding line" of security) which, in the case of a belt, could be subjected at inadequate torsion if there is lateral traction; they could even partially strangle him; In addition, if the chosen fixing element has edges, they can cut the webbing, belt or rope.

DESCRIPTION OF THE INVENTION

In order to overcome these inconveniences, the Novel device for anchoring irregular bodies, object of this technical report.

In general terms, the present invention refers to a new device that has several advantages over other traditional ones.

The first consists in the fact that the new anchoring device is fully recoverable and does not cause any deterioration in the structural elements of the building to which it is fixed.

The second is that the new device can be anchored indistinctly to both rectangular and non-rectangular and even asymmetrical morphology fixing elements.

The third advantage is that the novel device can be subjected to lateral traction without slipping from its position.

Another advantage is that, although it is subjected to lateral traction, the new device is made in such a way that it hardly suffers from strangulation or torsion.

Finally, the new device is protected against possible cuts due to the presence of edges in the fixing element.

The new anchoring device is essentially constituted by a non-elastic flexible belt or strap with high tensile strength, equipped with a suitable safety clasp, buckle, "ratchet" or similar, capable of closing the belt and at the same time tension it on the chosen fixing element (column, beam, railing, etc.).

The entire belt, or at least the inner face of the belt, is made of non-slip and resistant material, to prevent its slipping on the surface of the fixing element, as well as its deterioration, while it is being used.

The belt is provided with additional reinforcements, sliding along it, whose purpose is to rest more securely on the surface of the chosen fixing element, in addition to representing additional protection for the belt in the areas in which the fixing element has edges; each reinforcement is preferably constituted by an outer support, provided with a through hole for the belt and attached, by "sailboat" or the like, to an inner plate whose contact surface with the fixing element will be non-slip; These reinforcements are provided with a ring or equivalent means where a carabiner can be attached, in order to fix in one of them the "lifeline" or progression, and in the other, the "forwarding line" or safety.

The reinforcements can be linked to an additional elastic band, whose purpose is to prevent them from getting out of the belt, keeping them together and in turn attached to the closure.
