Description

Mooring device for safety elements and auxiliary means in building and civil works.

Object of the invention

The present invention relates to a device mooring, specially designed for fixing with character removable security elements and auxiliary means to fixed walls in building works and the like.

The object of the invention is to achieve a solid and effective mooring device, which results especially application in fixing net davit, body guard and railings, masts canopies to protect different building levels, eaves of hanging scaffolding on the eave, perimeter platforms transit on deck or on any other floor, temporary or definitive lifeline in plate or deck edge, temporary lifelines for formwork with vertical mast in pillars, scaffolding or electromotive columns, elevation of precast concrete slabs, safety elements in stairs such as railings or nets, protection of gaps in floor slabs, transverse loads, debris downspouts, etc, and can also be included in concrete structures prefabricated to tie security elements or means auxiliary

Background of the invention

In the field of practical application of the cited invention, clamp type moorings are conventionally used or cat that are fixed for example to the edges of the slabs, solution unsatisfactory both for the volumetry of the same and for the few security guarantees offered.

An alternative solution, growing use, is to arrange within the concrete, during the concreting of the plate or forged, a series of bushings that they are thus solidly bonded to concrete, which are subsequently trained to receive, by simple plugging, the masts, supports, davit or elements in question. This solution greatly simplifies the volumetry of the mooring and ensures perfect stability against stress descending or lateral, but nevertheless before efforts ascending can easily undock the masts, with the consequent risk involved.

Description of the invention

The mooring device that the invention proposes definitively solves the problem described above, so that belonging to the type of those mentioned last in the previous section, that is to say, those that have a receptacle intended to be embedded in the concrete mass, disable the mobility of the mast or element in question in any direction, both lateral and ascending.

To do this and more specifically in said mooring a hollow body, which determines the receptacle, participates previously cited, with an "L" profile, opened by the upper and free limb of its vertical branch, destined to remain embedded in the concrete mass, preferably with its mouth flush with the plate, hollow body externally provided with rods welded to it to improve its fixing conditions concrete. This receptacle or hollow body is complemented by a male element intended to constitute the lower extremity of the security element in question, or where appropriate the element filiar usable in the building in question, male element that It also adopts an L-profile, as a hollow body, but which is under-sized with respect to the latter so that you can penetrate its breast until it reaches its bottom, and once there it is movable so that its horizontal branch penetrates the branch likewise horizontal hollow body.

The structure described is complemented by a wedge also attachable inside the hollow body, once the male element has adopted its final position, for which purpose such a male element incorporates a side chamfer, opposite the branch horizontal of its profile "L", for wedge drive.

Finally, male element and wedge present in their faces facing each other slots destined to face each other in definitive situation of the assembly, constituting a keyway that it is located outside the hollow body and that consequently results accessible, for coupling a key that blocks the wedge making it impossible to accidentally exit it.

The key is related to the wedge by a chain that keeps these elements permanently attached, the male element incorporates laterally, in its area also intended to be left out of the hollow body, a hook to which the said chain, so that during the decoupling maneuver of the wedge, which is done by beating, there is no risk that such wedge may accidentally fall to the ground.

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 an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows an exploded perspective. of a mooring device for security and media elements auxiliary building and civil works, carried out in accordance with the object of the present invention.

Figure 2.- Shows a side elevation view and in section of the assembly represented in the previous figure, in the First assembly phase for it.

Figure 3.- Shows, finally, a representation similar to that of the previous figure in position definitive mounting of the device.

Preferred Embodiment of the Invention

In view of the figures outlined you can Observe how the device proposed by the invention is constituted from a hollow body (1), basically prismatic or rectangular, for which an upper opening is defined and rectangular (2), but with the particularity of presenting a lateral expansion (3) in its determining bottom for said body of an "L" profile.

This hollow body (1), intended to be embedded in the concrete constituting the plate, with its mouth (2) flush with the latter, it will preferably be provided with outer rods (4) of corrugated steel, conveniently welded to it, which improve the mooring of the body (1) to the concrete. Optionally I was able to carry plates as legs to nail in the mecca board in those forged that by its characteristics its use was convenient.

The body or base (1) is complemented by a connector (5) that ends the lower end of the mast or the element to tie in question, connector essentially prismatic, but with a lateral and inferior projection (6) intended to fit tightly into the lateral projection (3) of the body hollow (1), and with dimensions at its base (7) such that said connector is capable of penetrating through the mouth (2) of the body (1), until reaching the bottom of it, and later move transversely so that its projection (6) is lodge in turn in the projection (3) of the latter. Optionally can carry iron plates as legs to nail in the mecca board in those forged that by its characteristics its use was convenient.

Complementarily the connector (5) incorporates in its lateral side opposite the projection (6) a wide chamfer or inclined plane (8) intended to receive a complementary wedge (9), which is what causes the transverse displacement of the connector (5) inside the hollow body (1), once it has reached the bottom of the latter.

Thus, wedge (9) acts as a means of blocking for the connector (5) on the hollow body (1), and in turn said wedge (9) is locked by a key (10) joined by a chain (11) to the wedge itself (9), for which both the wedge (9) as the connector (5) have grooves (12-12 '), on their faces facing each other, which in the limit situation of coupling the wedge (9), the one shown in figure 3, are faced and they constitute a keyway for coupling within the mentioned key (10).

It only remains to note that the connector (5) is endowed, outside its level of interlocking in the hollow body (1), like the groove (12 '), with a hook (13) properly soldier himself, able to receive the chain (11) for one of his links, once the key (10) has been decoupled from the keyway (12-12 '), in order to prevent loss of the wedge (9) during the decoupling maneuver of the same.
