Description

IMPROVEMENTS IN ROAD SIDE PROTECTION STRUCTURES

Technique sector

The present invention is related to the protection structures that are arranged on the sides of the roads to prevent the exit

accidental

of the vehicles and in particular with the

structures

of that type planned with accessories of

protection for

the bikers.

State of the art

The project, construction and maintenance of vehicle containment systems on the roads, known as "SCVquot;", has been carried out in accordance with different regulations, among which Circular Order 321/95 T and P includes a system specific for the protection of motorcyclists.

In this sense, Circular Order 18/2004 establishes criteria for the use of protection systems for motorists and, in addition, defines a system developed by the General Directorate of Roads, which proposes as a preferred solution the use of structures that guarantee that motorists when sliding on the pavement, when they have an accident, cannot pass the protection barrier.

For this, solutions have been developed that consist of complementing the simple traditional structure formed by a bionda fastened to a certain height by supporting posts, with a screen located below, closing the space between the bionda.

top and ground, to prevent injured bikers from sliding below the

protection and impact against the support posts of the protection structure itself or other obstacles that are behind it.

In the known solutions of this type of protection structures, the fastening of the lower complementary screen is established by means of tie supports on the support posts of the structure and tie supports on the bionda

higher,

determining sayings supports of mooring a

certain

flexibility for cushion the impacts of

shock

against said complementary screen.

From European Patents EP 1,184,515 and EP 1,182,296, protection structures of this type are known, formed by an upper bionda that is fixed to supporting posts through pieces called spacers, providing below a lower screen that fastened by means of mooring supports on the supporting posts of the structure, taking advantage of the own fastening screws of the upper bionda on said supporting posts. This embodiment has the drawback that in order to mount the lower screen it is necessary to release the securing ties of the upper bionda, which makes assembly difficult.

The Spanish Patent P200900337 of the same owner as the present invention, contemplates the realization of such a protection structure with the lower screen mooring on the upper bionda with flexible pieces of sheet metal and on the supporting posts of the structure by other pieces

flexible sheet metal that are fixed on the support posts regardless of the ties of the upper bionda. This solution allows a simple and quick assembly of the lower screen, since it does not require loosening the ties of the upper bionda.

Object of the invention

According to the invention, improvements are proposed in the aforementioned road side protection structures that incorporate an upper bionda and a lower screen, determining structural characteristics that allow the lower screen to be mounted independently of

the

moorings of the bionda higher on  the poles, and

than

also establish a provision shock absorber of

the

screen lower in terms advantageous of

effectiveness and

security.

According to the invention, the lower screen of the protection structure is fastened on the upper bionda, which is supported by structural support posts, by means of mooring arms that comprise a section of rigid profile, which is fastened at one end directly on the upper bionda, incorporating in said end an angular plate, by means of which it makes a second support on the aforementioned upper bionda, while at the other end said section of rigid profile incorporates a piece in the form of "Jquot", by means of which fixation is established on the lower screen.

This mounting arrangement of the lower screen determines the holding conditions of said screen that make it flexible backwards when

it receives a frontal impact, but in such a way that the flexibility decreases as the deformation backwards progresses, with which said screen results from a very effective capacity of absorption of impacts in the first phase of the deformation backwards, but as it progresses the deformation the flexibility decreases, avoiding, in the case of the injured motorcyclists who slide on the road pavement, that they can pass under the protection structure.

The mooring arms between the lower screen and the upper bionda can be of a single piece, the end parts being determined as extensions of the ends of the rigid profile section, or with the rigid profile section and the end parts in independent pieces joined by tie together ', in this case, the section with a rigid profile may be a section with the same profile as the support posts

of

the structure  of protection, with the which I know get

a

realization plus economic of the set of the

structure

of protection.

Between the lower screen and the posts that support the upper bionda, there are also some pieces of bent sheet metal, with a part in the shape of "Uquot", from which an extension that determines to the outside on one side two successive inclined bankruptcies. According to an application form, said pieces are tied on the lower screen of

the protective structure by means of the lateral extension, or on the set of

support of the upper bionda by means of the part in the shape of "Uquot", so that only one of the parts is established, while on the other part support is established without mooring, which favors the elasticity of the assembly from the bottom screen. However, these pieces sandwiched between the lower screen and the support posts of the structure, can also be arranged tied to the two parts.

In this way an arrangement is achieved that allows the lower screen to be assembled with

total

independence of the subjection of the bionda

higher,

of way than saying mounting of the screen

lower

result simple and Quick, allowing the

incorporation of said lower screen both in new protection structures integrated with that screen, and in already installed protection structures, without having to carry out any disassembly of the same.

Therefore, the improvements of the invention determine some characteristics very

advantageous, acquiring the realization of the protection structure with said improvements own life and preferential character with respect to the protection structures that are known of the same function.

Detailed description of the invention

The object of the invention refers to a lateral protection structure for roads, of the type comprising an upper bionda (1) that is fastened by means of spacers (2) on posts

(3) of support that are arranged nailed to the ground, with a lower screen (4) going under said upper bionda (1) that closes the space of the protection to the ground, to avoid that the injured motorists slide down the road pavement may pass under the protection.

Both the upper bionda (1) and the lower screen (4) are made of sheet metal, with a cross section of corrugated shapes that provide rigidity, according to any conventional embodiment of the biondas that are used in road side protections; while the support posts (3) are made up of metal profiles, in "Cquot", tubular, or any other section

conventional support posts for protection structures of this type.

According to the invention, the lower screen (4) is held on the upper bionda (1) by means of arms (5) that comprise a section with a rigid profile (6), which is held at one end directly

on

the bionda higher (one), While than by the other

extreme

I know hold on the screen lower ( 4) by

means, medium

of a piece (7) in shape of quot; Jquot ;, such how I know

watch

in the figure 3.

At the clamping end on the upper bionda

(1) the section with a rigid profile (6) also incorporates an associated angular piece (8), by means of which it establishes a second support on the aforementioned upper bionda (1), as seen in the same figure 3.

In the practical embodiment, the structural assembly of the mentioned arms (5) can be of a single piece, the piece (7) being formed in the shape of "Jquot; and the angle piece (8) as extreme extensions of the rigid profile section (6); but preferably, an embodiment is provided with the three parts formed by independent parts, the section with a rigid profile (6), in this case, a section with the same profile as the posts (3) to support the structure, having said section of rigid profile (6) a torn hole (9), for the clamping of the piece (7) in the form of "Jquot", thus allowing to adjust the clamping height of the lower screen (4) as appropriate. Obviously also, without altering the functional concept, any of the end pieces (7, 8), can be formed as an extension of the section with a rigid profile (6) and the other can be a piece

Independent.

In relation to the posts (3) for supporting the structure, the lower screen (4) is supported by means of pieces (10) of bent sheet metal, which determine (Figures 4 and 5) a part (10.1) in "Uquot" shape, from which on one of the sides an extension (10.2) emerges towards the outside that determines two successive inclined breaks.

According to an application form, said pieces (10) are fastened in mooring, either on the lower screen (4), or on the structural assembly of the posts

(3)

of support, remaining in support, but without mooring, on the other part in each one of the cases, that is to say that, in this case, by means of those pieces

(

10) Support is established between the lower screen (4) and the support posts (3), but not a mooring relationship, thus determining a highly flexible elastic play between both parts. However, said pieces (10) can also be arranged with a tie on the lower screen (4) and on the structural assembly of the support posts (3).

According to a preferred embodiment, the fastening of the mentioned pieces (10) is established on the lower screen (4), by means of the extension

(10.2), through a torn hole (11) that allows height adjustment, while with the part

(10.1)

in the form of quot; Uquot; they remain in support, but without fastening of tie, on the posts (3) of support of the structure, as observed in figure 2. However, the arrangement can also be the reverse, that is to say with tie of the part

(10.1)

in the form of quot; Uquot; on the structural set of

the support posts (3) and with support without clamping the extension (10.2) on the lower screen

( 4) •

With all this, a set of the protection structure is obtained, in which the lower screen (4) is elastic to the rear when there are impacts from the front against it, allowing the impacts to be absorbed with a high absorption capacity. , so that thanks to the particular arrangement of the assembly of said lower screen (4), it results from a great elasticity backwards at the beginning of the deformation,
