Safety mooring for constructions.

Object of the invention

The present invention, as expressed in The statement of this specification refers to a tie of safety for constructions whose purpose consists in facilitate an anchor specially designed for protection in high falls, preferably in building construction, having been specially made to facilitate the coupling of Personal protective equipment against falls. The invention allows to provide buildings, and especially those that are they are in the process of construction, of points where hook any fall arrest system. For its simple way of installation, which allows taking advantage of structural elements of the own building, results from a very high reliability, low cost, and makes safety recalculations virtually unnecessary.

Background of the invention

The risk of workers or operators is known in building construction when they work at certain height, being mandatory through certain regulations security systems such as life cables, harnesses or others elements that are normally held at points of the building. These conventional fasteners have the drawback that they should be calculated in each particular case, also requiring specific hooks or structures that make the safety installation, in addition to not being as reliable as could be desired.

In this sense, there are currently the popularly known as consistent "ringed ropes" on a rope that has rings inserted between its cords to variable distances This solution is intended to be tied to some resistant element of the building and dropping by vertical walls coinciding with the areas where they are made works so that the multitude of rings will come to assume a element to which the worker exposed to the risk of falling (as per example on terraces, decks, viewpoints, windows, etc.) can hook your safety harness.

On the other hand, there is the patent with application number 200600255 stated as "mooring of security "which is applicable as security anchor for avoid high falls, preferably in the construction of buildings, and that is characterized because it constitutes a body central formed by a high resistance tape whose ends they form respective closed loops, so that one of the loops it is clamped on some element of the building while the other loop is connectable the cable, harness, carabiner or element of security of the corresponding operator.

In addition, there is a certificate of addition to the referred patent, which submits application number 200602982, characterized the aforementioned improvements because the referred body central and / or one or two of its loops have means of variation of its length in order to apply at various distances of interconnection.

We do not know in the current state of the art safety moorings for constructions with the characteristics of that presented in this invention.

Description of the invention

To achieve the objectives and avoid drawbacks indicated in previous sections, the invention it consists of a safety mooring for constructions that is Applicable as safety anchor to avoid falls from height, preferably in the construction of buildings, becoming a central body formed by a high resistance tape whose ends form respective closed loops or accommodate rings extreme, so that one of the loops or extreme ring is attachable in some element of the building, while the other Loop or extreme ring is connectable the cable, harness, carabiner or security element of the corresponding operator.

Novelly, according to the invention, said central body incorporates one or more intermediate rings that facilitate additional hooks to the security system. These intermediate rings can be arranged at varying distances. In addition, said rings can be arranged in the central body by knotting and / or by
sewing.

This seam can be shaped by a simple seam on the tape that constitutes the central body, determining a loop through which the corresponding ring passes intermediate, or that seam can be formed by mixed seam formed by a main seam, analogous to the referred to simple seam, followed by a sacrificial seam that acts as an energy absorber in case of mooring action in a fall and as a test of the state of mooring.

On the other hand, said central body can  optionally have a folded area "S" and sewn with a lower resistance than the resistance of the constituent tape of the central body, so that it constitutes a kind of fall energy absorber, "fuse" or "warning" when the mooring has acted exercising its security function or when the tie has been subjected to a certain effort.

The mooring of the invention may present optionally reinforcements in closed loops or other areas, as well how to optionally incorporate in any of its loops, or in both additional elements such as rings, hooks, carabiners or others. On the other hand, the aforementioned great tape resistance that constitutes to the tie up can be realized with rope, cable or other material of sufficient strength.

According to different embodiments of the invention, the aforementioned central body and / or one or two of its two loops can have means of varying its length. For example, these means may consist of a loop attached to the end of one of the loops and slide along the central body, so that the arrangement in one or another area of the loop determines a greater or Shorter mooring length.

In addition, according to different embodiments of the invention, at least one of the loops and / or the central body can incorporate waterproofing media that prevent the passage of moisture by capillarity inside the building structure in the cases in which the mooring is permanently inserted in said structure.

The aforementioned waterproofing media can consist of arranging a cover of plastic or similar material that cover at least one of the mooring loops, and / or provide the central body of an area impregnated with some element waterproofing, this area being arranged in close proximity to one of the mooring loops.

The mooring of the invention may be fixed to the structure of the building under construction, tying or hugging resistant elements, or it may be left embedded within the structure during the construction process.

As stated earlier, the rings intermediate can be attached to the main body by seams mixed that provide the following functions:

-

Main seam protection against the pulls resulting from the normal use of mooring.

-

Witness of the security status of the mooring or device.

-

Energy absorber from the fall of a worker insured by the mooring of the invention.

With the structure described, the invention has the main advantage of allowing to take advantage the strength of structural components of the building, such such as steel rods, joists, reinforced concrete or others, in addition to the auxiliary construction equipment. It can also be installed on steel rods additionally inserted for this purpose in the assembly of concrete. The device of the invention has the advantage that it allows an installation very fast with very high reliability and a noticeably cost low. On the other hand, when made with flat materials and not round, the mooring of the invention is not a problem for execute formwork structures, such as slabs or pillars, and does not imply a significant reduction in the resistance of these elements when the mooring of the invention is included in them.

The constructive characteristics of the mooring of the invention supposes a remarkable increase of security, as well as the incorporation of status controls and energy absorbers, against systems without them based on ringed ropes that They are currently using.

The use of non-metallic materials, such as tapes or plastics, for the construction of the mooring of the invention, allow to keep this installed until practically finish the work, at which time it can be cut with a Razor or similar, or just hide under the false ceiling. In addition, the use of these materials makes the subsequent impossible appearance of rust spots in the areas where it was installed the mooring of the invention, which supposes a remarkable advantage regarding moorings based on metallic elements. For all this, the mooring of the invention is very useful for the the vast majority of jobs with risk of falling to different levels, how are the works next to forged edges (lifting of partitions, for example, work in the environment of walls, gaps on walls, installation of aluminum, glass, carpentry execution of false ceiling, covered with ceilings, plaster moldings, roof work, etc.).

In short, it is a system of secured resistance fixation for multiple fixation security equipments. On the other hand, the use of mooring safety of the invention is also possible in structures metal of the building when it is of that nature, that is, It not only serves for reinforced concrete buildings but also for those of metal, wood or other structure.
