Description

Security system fixing means fall arrest for construction workers.

Object of the invention

The present invention aims at fixing means of a fall protection system for construction workers, which is fully recoverable not leaving no lost element neither in the formwork nor in the pillars

Characterizes the present invention, in addition to the fact of being fully recoverable, which means of fixation are adjustable to any pillar dimension, where it is also not necessary installation from a crane can be done from the lower floor.

Therefore the present invention is circumscribes within the scope of security systems employees in construction and more particularly among the safety systems designed to prevent falls from Operators through suspension systems.

Background of the invention

Construction safety is a priority  that each one takes on greater importance, designing more and more systems sophisticated in addition to adopting means, tools and procedures working all of them aimed at avoiding the high number of accidents that occur in construction.

Among the means of fixing the systems of safety employees in order to avoid the vacuum fall of operators from a certain height, such as a floor slab, there are some that are based on the use of stems or pins that are introduced into the reinforced concrete pillars, such and as shown in some embodiments described in the patent ES 2178610.

For the introduction of said means of fixing on the pillars, it is necessary to perform some cavities at the ends of them where the fall arrest systems

These fixing means have several inconveniences, such as having to leave or perform a recess in the upper end of the pillar, to introduce the end lower of the fall protection system. On the other hand they require the use of complex pieces to achieve a perfect coupling between the cavity left at the end of the pillar and the end of the system anti fall.

Furthermore, once the fixing means of the  fall arrest system at the end of the abutment remains a gap over said pillar, which produces a structural weakness of the whole general and in particular of the pillar.

On other occasions, the fixing means of the safety systems are based on the previous drawing of a rod or spike in the fresh concrete on the end of the pillar until the moment built, as shown in the patent ES 2264589 Although these safety systems fulfill the intended purpose, they have an inconvenience in the very nature of the means used, since on the one hand they are not fully recoverable, on the other hand their installation is required from a crane since they do not you can do it from the floor
lower.

On other occasions a system has been developed  for fixing the fall-based safety system based on employment of a set that is fixed by hugging a pillar, providing a tubular element on one of the sides, as shown in Figure 12 of the patent ES 2178610. This system however not It is free of inconvenience since any swing of the mast Makes it cimbree broadly transmitting vibrations to the whole safety system, in addition to the resistant torque that offers in its union with the rest of the elements that embrace the pillar it is limited by the union of the tubular element with the rest of the whole, not offering some means of sharing the efforts among other elements.

Therefore, it is the subject of this invention, develop means of fixing a system of fall protection for construction workers who exceed the previous drawbacks, of non-recoverability, that allow greater ease of installation, in addition to avoiding a side, excessive dimming of security systems, and counting on the other, with means that allow a greater distribution of efforts to which the fixing means of the fall safety system.

Description of the invention

The invention proposed means of fixing a fall arrest security system basically involves the use of three sheets of steel, plates, plates or the like, two of them faced and joined together and a third steel plate that It is joined with the previous ones, presenting a stem or massif pop-up in which the lower end of the mast of the security system.

Thanks to the structural characteristics that present the fixing means object of the invention are achieved several advantages:

-

for side, fixing means as well as security systems fixed to them are fully recoverable in full, being also reusable,

-

by On the other hand, the fixing means are adjustable to any width of pillar,

-

also fixing means do not need to be installed from a crane can be done from the lower floor.

-

Be prevents the buzzing or pitching of security systems.

In order to adjust the fixing means to any width of the pillar the three fixing plates have width adjustment means based on openings longitudinal, or oblong grooves as slides.

Description of the drawings

To complement the description that then it will be done and in order to help a better understanding of its characteristics, is accompanied by this descriptive memory, of a set of planes in whose figures, of illustrative and non-limiting, the details are represented significant of the invention.

Figure 1. Shows a schematic representation  in perspective of a slab on which a pillar is represented at whose upper end the fixing means of A security system.

Figure 2 shows a detailed representation from the end of a pillar on which the means of fixation object of the invention.

Figure 3, shows in an enlarged way the previous representation in which all the details of the construction elements of the fixing means object of the invention.

Preferred Embodiment of the Invention

In view of the figures described then a preferred embodiment of the invention proposal.

In figure 1 we observe the representation of a safety system consisting of a mast (1) fixed on the upper end of a pillar (16). On top of the mast (1) there is a triangular structure (2) that can rotate with respect to the mast thanks to its swivel joints (3) with which bill. The rotation that the triangular structure can make (2) with respect to the mast (1) it is 360 °, that is, it has a degree of freedom.

The security system shown is fixed on the pillar (16) by means of the fixing means (4), which allows the construction of the floor (5) with levels of increased security.

In Figure 2, we look at the elements that make up the fixing means (4), which are made up of two preferably metal plates, plates or the like arranged of facing way. Both plates (7) and (8) have a "T" shape inverted, the plate (7) being shorter than the plate (8) and being linked both plates (7) and (8) by their ends upper with an "L" shaped plate (6) on which it is fixed the mast (1).

The "L" shaped piece has a vertical and horizontal section that is supported on the part top of the pillar so far built, emerging from said horizontal section and a centrally arranged rod or solid on which the lower end of the mast of the system is fixed security.

The heads of both "T" plates (7) and (8) are arranged in a confrontational manner, providing each of the plates with oblong or sliding grooves (9) and (10) respectively, which are also arranged facing each other, which allows adjustment to the dimensions of the pillar.

The fixing between both plates (7) and (8) is made by means of threaded rods (11) that through the oblong grooves (9) and (10) respectively are fixed by means of nuts or the like (12).

In figure 3, we observe how the plate (8) in its upper part is linked with the vertical section of the plate in "L" (6), by means of fixing screws (17) that pass through perforations facing both plates ( 8)
and (6).

On the other hand, we also observe that the piece (7) presents on its upper end for its union with the plate (6), vertical threaded rods or rods (14), which they pass through oblong or sliding grooves (13) over the horizontal section of the "L" plate (6) to adjust to the other of the dimensions of the pillar.

It is noteworthy the presence on the center of the horizontal section of the "L" plate (6) of a massif or stem (15) vertical pop-up on which the lower end is anchored of the mast (1).

Thanks to the centered arrangement of the stem or massif (15), the cimbreo or pitching that could suffer the system of security is reduced, in addition to that reason because of the fact be jointly attached to some plates that in almost all its surface contact the pillar, so the surface of transmission of efforts on the pillar, is not punctual but is found distributed, which clearly results in an increase in the levels of efforts at which the security system can be subdued without breaking.

It is not considered necessary to extend this  description so that any subject matter expert understands the scope of the invention and the advantages thereof drift

The materials, shape size and layout of the elements will be subject to variation as long as they do not alter the essentiality of the invention.

The terms in which this report has been described they should always be taken in a broad and non-limiting sense.
