DESCRIPTION

Fixing system for posts of vertical traffic signaling elements and the like

Technical Field of the Invention

The present invention falls within the technical field of vertical traffic signaling and, particularly, in the sector of vertical signaling elements comprising posts anchored in the ground, such as traffic regulation, danger, information, and of works, beacons and indicator bollards, which are mounted on streets, roads, highways, highways, airport runways, and the like.

Background of the invention

Vertical signaling elements comprising posts anchored in the ground, such as traffic regulation, danger, information, and construction signs, beacons and indicator bollards, are essential elements for traffic safety on streets, roads, highways, highways , take-off and landing strips at airports, and the like. They are arranged in large numbers and, being close to cars, motorcycles and trucks in the case of road traffic and aircraft in the case of airport runways, are exposed to such vehicles impacting them with greater or lesser force against them , so the posts bend or even break completely quite frequently. For this reason, the posts and their anchors, due to their large existing number and the high frequency with which they suffer impacts, must be economical, both in terms of manufacturing and in terms of maintenance costs, both at the first level installation as when the posts that are damaged must be replaced by new ones. On the other hand, the structure of such posts, including their anchoring in the ground, must present a balance between a sufficient solidity to resist strong gusts of wind, acts of vandalism and impacts of lesser degree and a sufficient weakness to yield or bend from of certain impact force to avoid damage to vehicles and, in the case of motorcycles, also to motorists who are especially exposed to injuries.

A large number of posts and post anchors are known with the intention of achieving the qualities mentioned above. Thus, patent documents EP-A-1676960, EP-A-1911912, JP-A-20011132272, JP— A-2006022495, JP-A-2007297897 JP-A-2009007142, JP-A-2009068235, US-A -5400997, US-A-5625988, US-A-5848502 and WO-A-00/39402, and many others, describe post anchors comprising a base element that is anchored in the ground provided with an internal housing in the that the lower end of the post is immobilized by bars, wedges, or other elements that are arranged in the base element. Patent document GB-A-2272717 describes a bollard that threads into a stud protruding from a base element and document FR-A-2893957 describes a fixing system comprising an O-profile bolted to a concrete piece arranged on the ground, on which the pole of a traffic signal is screwed. On the other hand, to allow posts to yield to minor impacts, posts or anchors have been designed for posts that include tilting elements such as springs, spring or flexible inserts, such as those described, for example, in the documents of Patent DE-A-102008045788, FR-A-2641557, FR-A-1388584, FR-A-2836166, JP-A-6220815, JP-A-6173226, JP-A-2004/332284, JP-A-2003106011 , WO-A-99/49140, WO-A-2006/070788 and WO-A-2007/125137.

Other patent documents, such as, for example, FR-A-2914329, GB-2431955, US-A-4133125, US-A-5125194, and US-A-6516573 disclose posts with areas of controlled breakage through weakening zones or special unions.

Document DE202006008338U discloses a fixing system for posts of vertical traffic signaling elements and the like with the features of the preamble of claim 1.

The fixing systems or anchors described in these documents do not combine a simple and economical structure with a firm anchoring of the post on the ground and with easy mounting of the post.

Description of the invention

The object of the present invention is to overcome the drawbacks of the prior art indicated above, by means of a fixing system according to claim 1 for posts of vertical traffic signaling elements and the like comprising an anchoring piece which, in the position of assembly of the system, is inserted in a concrete block arranged on the ground, the anchoring part comprising a vertical axial cavity and an upper end from which a perimeter wing or edge emerges resting on the floor surface, fixing means for fixing a post to the anchoring piece and immobilization means to immobilize the fixing means in the anchoring piece, a flange element with a bottom plate screwable to the perimeter wing of the anchoring piece and a clamp comprising a joint part and two tightening arms ..

This system, apart from guaranteeing a secure post fixing, also allows a simple and quick first installation of the traffic signal, as well as a quick and easy replacement of a damaged traffic signal with a new one.

In order to install the traffic signal, it is sufficient to insert its lower end part of its post through the clamping hole and the through hole in the lower plate of the flange element, in the vertical axial cavity of the anchoring element and

tighten the clamp arms. On the other hand, to uninstall the traffic signal, simply release the clamp arms and remove the post.

According to a first embodiment of the invention, the system comprises a plurality of anchor studs comprising lower parts immobilized in the perimeter wing of the anchoring piece and two threaded upper parts that emerge vertically from the perimeter wing of the anchoring piece and pass through respective upper mounting holes in the lower plate of the flange element. At the top of each stud thread an anchor nut. The lower parts of the studs can be integral to the perimeter wing, or they can penetrate through two lower mounting holes in the perimeter wing and comprise thickening, such as for example screw heads, of larger dimensions than those lower mounting holes. According to this first embodiment, the anchoring piece provided with the studs can be introduced first into the concrete before setting and then screw the flange element to the studs. Alternatively, it is also possible to screw the flange element to the anchor piece, insert the post through the flange element into the axial cavity of the anchor piece, tighten the clamping screw of the flange element, position the assembly thus formed in a hole in the ground and finally pour concrete filling into the hole, so that the concrete, once set, fix the assembly on the ground. Likewise, it is possible to first position the anchor piece in a hole in the ground, pour filling concrete into the hole, wait for the concrete to set and form the concrete block, screw the flange element to the anchor piece, Insert the post through the flange element into the axial cavity of the anchoring piece, and tighten the clamp using the clamping screw to immobilize the post.

According to a second embodiment of the invention, the lower plate of the flange element has a plurality of upper mounting holes and the perimeter wing of the anchoring piece has a plurality of lower mounting holes for the passage of two anchoring screws that anchor the flange element and the perimeter wing to the concrete block, for example by means of respective chocks introduced in the concrete block before setting or in holes made in the set concrete block, to then screw the flange element together with the perimeter wing to the concrete block.

As in the first embodiment described above, an anchor nut is threaded on the top threaded part of each stud. According to this third embodiment, the lower parts of the studs can be immobilized in the concrete block by means of respective plugs introduced in the concrete block before setting or in drills made in the set concrete block so that the flange element is screwed together with the perimeter wing to the concrete block.

These embodiments allow, on the one hand, an easy and fast first assembly of the anchoring element and the flange element and, on the other, an easy and rapid disassembly in the event that those elements are damaged at some time. In order to strengthen the anchoring of the anchoring piece in the concrete block during the setting of the concrete, the anchoring part, when initially positioned in a hole in ground in concrete without setting, may be provided with radial anchoring elements that project radially. of its body intended to increase the contact surface between the concrete and the anchoring piece, such as pins, ribs, ribs, ribs.

When the cross section of the section of the post that is housed in the anchoring piece and that is trapped by the flange element has a quadrangular section, the lower through hole of the lower plate and the tightening passage have quadrangular cross sections. On the other hand, when the cross section of the section of the post that is housed in the anchoring piece and that is trapped by the flange element has a circular section, the lower through hole of the lower plate and the tightening passage have cross sections Circular To facilitate the correct positioning of the post, the bottom of the vertical axial cavity of the anchoring element may be provided with a centering element, such as, for example, a centering cone sized to enter inferiorly into a post recess or a cavity with reverse frustoconical walls complementary to the shape of the lower end of the post.

According to the invention, the post may be provided with a weakening zone in a lower end part of the post.

This weakening zone may comprise, for example, at least one groove, and may be arranged such that, when the lower end part is inserted into the inner cavity of the anchoring element, it is surrounded by the joining part of the flange and / or located in a section immediately above the joint part of the flange element. This position of the weakening zone has the advantages that it is hidden and that the loss of the mechanical resistance of the post is compensated to some extent by its mechanical connection with the flange element.

It follows from the foregoing description that the present invention achieves the previously defined object in a simple, economical and reliable manner.
