Description

Protector for threaded rod anchors.

Object of the invention

The present invention relates to a protector, which has been specially designed for the classic anchors to floor of different objects such as street lamps, banners, motors, equipment, etc., anchors consisting of a threaded rod or asparagus, which emerges in solidarity from the ground and that, going through a hole of the piece or element to be fixed receives a nut of fixing, with the corresponding washer.

The object of the invention is to protect said anchor against the environmental effects, avoiding the classics oxidation problems and, as a consequence of them, the difficulty or inability to disassemble the nut when necessary manipulate over the anchor.

Background of the invention

When an object must be fixed immovably to the ground, such as a signage banner, an engine, etc, threaded rods or studs are commonly used partially immersed in a concrete shoe operatively established on the ground, so that said rods or studs emerge vertically from the concrete and, through holes in the base of the object in question, receive complementary nuts with which the definitive fixation occurs.

This solution, perfectly valid from the theoretical point of view, presents in practice problems of subsequent disassembly, since the threaded rods remain totally in the air, occurring over time a progressive oxidation that causes an eventual need for disassemble the anchor, it is impossible to unscrew the nuts, having to proceed to cut the rods or studs with the contest of a radial or a torch.

But the fundamental problem is not the need to cut the rods or asparagus, but once cut the anchors are destroyed, so if what is intended is not it is the definitive withdrawal of the object in question, but its temporary withdrawal or replacement by another, it is necessary to break the concrete shoe to then develop a new shoe in which they can be inserted and properly fixed the new rods or studs that allow to make the new anchors

Description of the invention

The protector proposed by the invention resolves fully satisfactory way the problem above exposed, since it ensures a perfect state of conservation both for threaded rods or studs and for complementary nuts and other accessories, which are maintained indefinitely over time and that allow easy loosening and decoupling of the nuts, obviously with possibility of reuse.

For this, and more specifically, said protector is materialized in a plastic body that configures a kind of formally and dimensionally suitable bowl to receive in its bosom, with sufficient clearance, the prominent sector of the stud or threaded rod, and its complementary nut and washer, body provided at the level of its mouth with an annular wall of adaptation to the surface of the piece or element to be fixed, whose front face is provided with an
double layer adhesive for fixing the protector.

As a complement to the structure described in the Inside the aforementioned body is a sponge, which by its own nature is highly deformable and adapts perfectly both the threaded rod and the nut, being this sponge impregnated in oil or other similar product capable of keep the stud in optimal conditions of both protection as a lubrication to facilitate the disassembly of the nut.

Obviously the double layer adhesive tape will be assisted in principle by a disc of paraffined paper, siliconized or similar that protects the adhesive until the moment of its use and close the hollow interior of the leather to avoid access of dust to the sponge impregnated in oil.

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 view in perspective, a protector for threaded rod anchors carried out in accordance with the object of the present invention, the which appears with the protective sheet of its adhesive partially detached to show said adhesive.

Figure 2.- Shows a side elevation view and in diametral section of the same protector, duly coupled to a threaded rod, in work situation.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the protector that is recommended is constituted to from a body (1) of a plastic nature, which configures a cylindrical bowl of adequate diameter and depth to the set consisting of the stud or threaded rod (2) to which it is intended its corresponding nut (3), preferably with a remarkable oversizing with respect to the latter, as is it follows from the observation of figure 2, incorporating said body (1) at the level of its mouth a perimeter expansion determinant of an annular wall (4) that is intended to enter in contact with the base of the piece (5) to be fixed to the shoe concrete (6) implanted in the ground, and in which it is located conveniently set the bottom of the stud (2), as also seen in figure 2.

The plastic body (1) houses inside to a sponge (7) which in turn configures an inverted bowl under-sized with respect to the stud (2), so that at coupling the latter undergoes a deformation that ensures the maintaining intimate contact between both elements, or what it is the same, a constant impregnation of the stud (2) in the oil of which the sponge is carrier (7), which ensures the optimal preservation conditions for said asparagus, as well as for the nut (3) that complements it, and where appropriate the washer or washers

To get a protector seal, as well as better protection of the same, it is planned that in the front the Walloon (4) a double-sided adhesive ring (8) is established, which consequently it is fixed through one of them to the Walloon (4) while through the other it does so at the base of the object (5) to fix, so that this adhesive (8) seals the protector proper against the element or part (5) to be fixed, preventing any communication between the camera defined by the body (1) and the outside.

Until the use of the protector, the adhesive (8) is in turn properly protected by means of a sheet (9) of paraffin paper, silicon or similar, specifically disk-shaped, as seen in the figure 1, which not only protects the adhesive (8) but closes the inside hollow of the protector, preventing the access of dirt to the sponge (7) impregnated with grease or other similar product capable of keep the asparagus (2) in optimal conditions.
