Description

Metal barrier protection.

Metal protection barrier type especially used in bridges, viaducts or the like, characterized by comprising a series of trunk posts pyramidal, without sharp edges, arranged at a distance equidistant, being able to vary this according to its dimensions and screwed by bolts housed in the wing concrete or overhang of the bridge itself. Frontally it has several sections tubular square section, housed on the pole by fasteners and arranged at different heights.

Various types of barriers consisting of three railings supported on posts anchored to the concrete, said posts must be constituted of a considerable thickness to present a good mechanical resistance, and above all a buckling resistance, its weight being very high It can make placement operations difficult.

Another important problem presented by the Current barrier protections is the ease of breakage of tie down fasteners at the moment of impact, because are moorings anchored on the concrete lacking all ductility

In addition, it has been widely used a bionda or similar metal containment barrier, which undoubtedly protects vehicle users, preventing them from going outside the road, but as an inconvenience we can mention that for the protection of users of motorcycles and bicycles are not so effective.

A major drawback is that when a Biker or cyclist loses verticality and suffers a fall, motivated by any cause, by the inertia of the speed, greater in a biker, the direct impact is received by the body on the metallic protection in some cases, in others, more serious, the motorcyclist tends to go under the protection of barrier, contacting her, being able to cause mutilations and In the worst case, lose your life.

The main drawback is that the space that remains free between the floor of the road and the bionda protection or any other, it is very dangerous for users of motorcycles in general, this user sector being very unprotected

To solve the problem in the Nowadays, the metallic protection barrier designed for the present invention, which is comprised by the following elements:

Posts or pillars : constituted of a pyramidal trunk shape, hollow, having a full front with rounded ends, providing the post with maximum safety, being all rounded edges.

On the mentioned front are arranged brackets anchored by screws, for the subsequent securing of Tubular sections of square section. The supports are located at equidistant distance, leaving a distance at the bottom minimum to avoid sliding below the barrier of the people, guaranteeing perfect security.

The mentioned supports are constituted by a rectangular plate endowed at its four ends with a hole torn to favor its anchor on the pole, both in its part lower as in the upper one has two welded supports perpendicularly and semicircularly, with the two remaining sufficient distance for the tubular section of square section, which It will be fastened by rivets.

The supports can be the same or different each other, being able to vary the dimensions for the accommodation of the tubular sections, allowing the assembly of tubular sections wider or narrower depending on the needs of the barrier protection

The pole has at its bottom a flat support plate welded to the pyramidal trunk structure, the which has two torn holes located in its central part and close to both sides, placing in its front part a "L" bracket that also has four torn holes to allow anchoring with bolts housed in concrete by nuts and lock washers.

The support plate has two holes larger diameter to allow drainage of water that can accumulate on the poles because of the rains.

Tie the post with the wing or cantilever of the bridge : a flat plate, similar in size to the lower plate of the post, which is related to a lower support in "H", is anchored on the concrete over the wing or cantilever of the bridge, joined together by incorporating the anchor bolts welded to the plate and the "H" bracket, limiting the height of the outer coupling with the protection post.

The assembly is done by positioning the slots of the post plate over the protruding bolts of the plate anchored in the concrete, followed by blocking washers and nuts the fastening is done by adjusting the torque of tighten accordingly.

The four front fastening bolts, during the concreting process is covered with a sheath to increase its ductility, preventing bolts from adhering to concrete.

The two rear bolts are not incorporated no type of sheath, adhering with the concrete, to absorb as much as possible the impact that may occur on the protective barrier

The union of the nuts with the bolts can be cover with protectors to increase safety in case of impacts, being able to manufacture in different colors and with the possibility of incorporating reflective material.

The protector that covers the bolts located in the support of the front face of the post is constituted rectangular, with its circular circular front face, while the protectors of the two rear bolts are constituted semicircular.

Union between the different tubular sections of square section : it is constituted by the introduction of a small tubular section of square section inside the main one, being located between the union of two sections, proceeding to the drilling and later riveting of both structural elements, leaving the sections together along the barrier of the entire bridge, being a simple assembly and in case of accident can be repaired without any setback.

In addition, the sections that make up the structure they can be painted with bright colors and even incorporate reflective material.

This protective metal barrier that presents brings multiple advantages over similar systems currently available, the most important being lightness of the set to be the posts constituted by a structure high strength hollow pyramidal trunk.

Another of the most important advantages is that anchor bolts when wrapped in polyethylene sheath, not are adhered to the concrete increasing its ductibility, avoiding Breaks in case of impact.

Another important advantage is the assembly can be easily perform without having to resort to labor specialized, being a simple and fast assembly in its execution, in the same way the repairs in case of accident are carried out without No setback

Another advantage of the present invention is the protection that is performed on the free space that currently exists between the bionda profile and the floor of the roadway, protecting to the users of motorcycles and bicycles, because in case of an accident Minorizes the impact of the body on the protective barrier, preventing the body from getting fired towards the road or out of the road.

Another important advantage is the display of the protective barrier when it can be painted with bright colors and even incorporate reflective material.

As an advantage we can add that you can incorporate protectors on the lower base of manufactured posts in different colors incorporating reflective material.
