Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] The present invention relates to a road safety barrier in which a dividing wall for a normal road or a two-lane road can be simply, quickly and economically installed. The present invention also provides a method of manufacturing a movable, semi-rigid, removable or fixed barrier. To date, U.S. Patent Nos. 4,348,133 and 4,4
Various solutions using other heavy materials, such as concrete, sand or crushed stone, as disclosed in US Pat.
It has been proposed to install road safety bulkheads. The construction of barriers according to the method of the above-mentioned patent is based on the same basic concept for these structures and only changes in the materials used for the barriers themselves and in the way they are finished and fixed to the ground. .

Regardless of the method of anchoring to the ground used for the barriers described in the two US patents, the limitations that exist on both of them lie in their rigid structure and method of anchoring to the ground, In the case of an accident where one side is closed, some of the barriers cannot be removed, and thus the passage cannot be opened to mitigate the traffic disruptions caused by the accident. As a technical background, the applicant can cite Spanish Patent No. 87-02657, in which the method of manufacturing a road dividing wall or a safety barrier in situ disclosed in a barrier or dividing Utilize molds made of lightweight materials placed where the wall will be installed, and materials appropriate for these molds (concrete or similar)
To fill some blocks and form a dividing wall or barrier.

While this method solves the problems posed by the US patent, it does not provide a different method of operation and is designed to fill only concrete or similar materials. The disadvantage is therefore that the wall thickness is considerably increased so as to provide sufficient resistance to the filling material. It is an object of the improvement according to the invention to completely, effectively and economically solve the problems caused by the above-described structure of the barrier or the dividing wall. To this end, the molds produced to achieve the objects of the present invention have one or more top holes for filling and draining when water is used as the filling material, the molds being sporadic. It is convenient to construct a separation wall in road repair or improvement work to be carried out.

[0004] In accordance with another object of the present invention, the mold is provided with a series of internal braces that enhance resistance to cracking or damage caused by the weight of the fill material. According to another object of the invention, the mold is made in two, male, female types. The male mold has side projections that fit into the complementary recesses of the female mold, so that even a barrier in place can be disassembled by lifting one of the molds and then simply moving the other. The dies can be provided with lateral keyed rods to create a decomposable barrier, since these keyed rods act as joints between the dies and thus between the modules. The device can also make up a stiffening device in which the mold is provided with horizontal bars which are perpendicular to the sides and makes the barrier rigid. Finally, the module is anchored to a tar corresponding to the ground or road, fixed and forms a rigid barrier in the manner described above.

In order that the features of the device may be more readily understood, it will be described in detail hereinafter, by way of example, but not by way of limitation, with reference to the accompanying drawings, in which:
As shown, the proposed barrier is composed of modules 1 and 1 ', the former being a male module and the latter being a female module. These modules are 2m long
Preferably, other lengths are possible, each weighing about 32 kg. They are made from a composite of polyester resin fibers and are structurally designed to withstand the hydrostatic pressure exerted by the filling material (concrete, water, sand, etc.).

The only difference between the two modules is that the male module 1 has a vertical projection 2 on its end face, while the female module 1 'has a complementary recess 3. With regard to the other properties of these modules 1 and 1 ', they are the same, and the clear holes 4 on their top surface can be provided with a valve for extracting water used as filling material, if desired, for example in mobile road construction. It can also be provided. As shown in FIG. 1, the barrier is to install empty male and female modules 1 and 1 'alternately in alignment with the projections 2 of the male module 1 in the recesses 3 of the female module 1'. Manufactured. This is carried out directly on the tar or wear layer 5 of the road, and the modules are filled through the charging holes 4. When the module is full, these holes or mouths 4
Is closed or left in place.

This barrier can be separated at any point by lifting one of the male modules 1 with a crane and starting the work of removing the adjacent module. At their base, said modules 1 and 1 'have lateral passages or outlets 6 through which rainwater can circulate, and inside these modules 1 and 1' streaks or ribs 7 across the main wall 8 and Have other streaks or ribs 9 extending parallel to them.
FIG. 3 shows in detail the arrangement of these streaks or ribs 7, 9 inside the main wall 8 of the module, where it can be seen that the number of transverse streaks 7 is doubled in the lower part.

Finally, the manufacture of the barrier according to the method described above does not require that the module 1, 1 'be fixed to the ground or tar 5, since the module does not float due to the flat bottom. With regard to the structure of the modules 1 and 1 ', and in view of the material from which they are made, areas can be reserved where the wall thickness is small, which further connects when filling holes or making water passages It can even be destroyed to install elements or to make a continuous module sturdy, making anchors to the ground. In this regard, the basic module can constitute or install at least four types of barriers. Barriers used for mobile road construction, articulated barriers, rigid barriers, rigid and fixed barriers, and ecological barriers.

With respect to barriers of the type used in mobile road construction, barriers filled with water or other light and easily fillable material, in which the modules 1 and 1 'shown in FIG. Can be easily moved. This type of barrier is ideal for protecting workers performing road works. In this case, the module is provided with electrical contacts that close the circuit, and when an accident interrupts the continuity of the module, an optical and / or audible alarm is activated in the area where the operator is working by disabling the relay. . With respect to the articulated barrier, the difference that arises is that modules 1 and 1 'have an L-shaped fitting 10 and a keyed rod 11, respectively, so that the articulated joint has: a) an impact having a component perpendicular to the barrier itself Absorb energy and b) be able to break down the module at any time. FIG. 4 shows the articulated barrier.

With respect to rigid barriers, these include the insertion of a curved rod 12 into an opposed module assembly, with modules 1 and 1 'preferably having two bottomed orifices at their end faces, preferably at each end face. And the set of successive modules 1 and 1 'can be fixed. This structure is shown in FIG. Finally, in a fixed rigid type barrier, the modules 1 and 1 ', which are not assembled with the curved rods 12 as in the above example, are vertically or curved partially installed in the lower orifice of each module. The rod 13 is fixed to the floor or tar 5 by a gutter rod 13, and a part of them enters into a concrete mortar 14 applied to the floor or tar 5. This type of barrier is illustrated in detail in FIG.
