Description

Safety railing for floor slabs in construction.

Object of the invention

The present invention relates to a safety railing, of those used as enclosure temporal perimeter of a floor during the construction of a work, specifically until the perimeter enclosure is done of it through the corresponding facade wall.

The object of the invention is to achieve a safe and effective railing, which does not create assembly problems, which be able to form sections in alignment or with any angulation, with a high degree of mechanical resistance and with a Optimal aesthetic finish that has a positive impact on appearance General of the work.

Background of the invention

To solve the risk of accidents due to falling to the emptiness that supposes that the floor or the floors of a building under construction lack perimeter protection, they are used protective railings that are mounted at the time when the slab ends and they remain until the moment in which It establishes the perimeter and final closure of the work.

These railings usually materialize in metal posts attachable in previously implanted records in the concrete constituting the slab, so that these posts have side appendages, like hooks, which allow the coupling of wooden planks, to different heights, which offer relative stability, since they are free to move both longitudinally and in upward direction These boards are heavy, they twist due to the effects of the weather, they are not much less suitable to constitute informational media, and create assembly problems when the posts are not spaced to the proper extent, by error in the implementation of the complementary records, as well as also when the railing undergoes bending in its trajectory along the perimeter of the floor.

Plastic fences are also known, by way of molded lattices that are also attached to implanted posts on the floor, solution that although it solves some of the problems mentioned above, considerably improving the aesthetics of the safety railing, allowing the incorporation of any type of information, and ensuring better stability, they present certain problems fragility and especially assembly problems since they require a very precise positioning of the caps for implantation of the posts, since the modules or plastic fences have a In turn, invariable dimensions. It also maintains the problem derived from inflections in the railing path along the perimeter of the floor.

Description of the invention

The safety railing that the invention proposes to solve the problem fully satisfactorily previously exposed, constituting a simple solution and effective, highly versatile and with optimal performance.

To do this, more specifically and from the classic posts marginally fixed to the floor with the collaboration of records previously implanted in the latter, the railing of the invention focuses its characteristics on the fact that each of these posts incorporates, duly fixed to it and at preset height levels, respective bushings, preferably cylindrical, to each of which a kind of clamp associated with one of the rails of the railing, participating in said clamp a piece in "L" of vertical and descending major branch, able to lodge inside the corresponding bushing and with its tip slightly widened bottom, complementing the clamp with a second piece, also of configuration in "L", one of whose branches is intended to adapt externally to the bushing in solidarity with the post, to establish the proper fixation on it last, while its other branch, the horizontal, is sliding with with respect to the also horizontal branch of the first piece, interacting with her through a strap and a lever tilting, which in a closed situation causes vertical branches of both pieces fit together constituting a ring that surrounds the wall of the corresponding socket.

According to another of the characteristics of the invention, each stringer is telescopic, based on profiles of aluminum, so that the effective length of said stringer is self-regulating in the closing operation of the extreme clamps, to those that are duly fixed said profiles.

The nature of these stringers, specifically extruded aluminum, allows easy customization of the railing.

The slack with which the vertical branch of the "L" piece attaches to the cylindrical bushing allows a wide lateral turn for said piece, and consequently for the consequent railing of the railing, allowing the formation of angles in the trajectory of it, of any amplitude required by the characteristics of the floor.

Obviously the stringers can be fixed to the posts with a fixed turn clamp, in the absence of braces and tilt lever, at the expense of reduced safety in the coupling of the brace to the post, or any another system for said fixation, such as a spring that shop to automatically close the clamp and make it practicable manually, or another.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic in perspective, a section of safety railing for floors in construction work, carried out in accordance with the object of the present invention.

Figure 2.- Shows an enlarged detail of one of the clamps for fixing the rails of the railing to the complementary posts of the same
ma.

Figure 3.- Shows a detail in perspective of one of the pieces that participate in the fixing clamp of each spar to the posts.

Figure 4.- Shows an enlarged detail of one of the mentioned stringers, at the level of the area of the same that It confers its telescopic character.

Preferred Embodiment of the Invention

In view of the figures outlined, especially of figures 1 and 4, can be seen as the railing of security that the invention proposes part of the use of posts (1), intended to be inserted in registers (2), generally of plastic, previously embedded in the concrete constituting the forged, before setting it, and determining the adequate distance between successive posts (1).

Well, according to the invention, each post (1) incorporates, at different levels in height, the planned according to the classic containment stringers (3), at least their respective bushings (4), which are fixed by welding to the post (1) in parallel arrangement to the axis of the latter, and which may be cylindrical, ie materialize in section tubes circular, with a length appropriate to the width of the stringers (3), as can be seen from the observation in figure 1.

Each of these bushings (4) is intended to receive a "L" part (5) inside it, shown in detail in Figure 3, for which a horizontal branch (6) and a vertical branch are defined. (7), the horizontal branch (6) being topped by its free end on a fork (8) with a pair of coaxial holes (9), while the vertical branch (7) is topped by its free end in a small expansion (10) oriented in the same direction as the other branch (6) but sized so that it is capable of
pass through the bushing (4).

The vertical branch (7) of the piece in "L" (5) It has an internal length according to the axial dimension of the bushing (4), in order to fit the latter between the branch (6) and the expansion (10) of said piece (5).

The fork (8) is intended to mount the shaft (11) of a tie rod (12) that relates the piece (5) with a lever or lever (13) connected in turn articulated to a second piece in "L" (14) whose vertical and descending branch (15) complete with the vertical branch (7) of the piece (5) the clamp for fixing the crossbar (3) corresponding to the bushing (4) of the post (1), as can be seen from the observation in figure 2.

This second piece in "L" (14) is fixed, preferably with the collaboration of thymes or rivets (16) to corresponding end of the stringer (3), which materializes in a pair of aluminum profiles (3-3 '), of identical rectangular and flattened section, related to each other by means of a section of intermediate tube (17), whose external section matches the internal section of the profiles (3-3 '), which is fixed interchangeably to one any of them and that turns each stringer into an element telescopic, as seen in Figure 4, so that any error in the implantation of the bushings (2) on the Forged, however considerable it may be, can be absorbed through the possibility of longitudinal regulation of the stringers (3-3 ').

Although in the drawings it has been represented exclusively a socket (4) in solidarity with the post (1), at the level of each of the stringers (3), it is evident that said post (4) have at least two sets of bushings (4) opposed to establish modular continuity in the railing.
