〔Example〕

Other advantages and preferred features of the barrier assembly according to the invention will become more apparent from the description of some embodiments given below by way of example with reference to the drawings.

As shown in FIG. 1, the barrier assembly includes a main member 1 and a connecting member 2 that integrates the main members to secure continuity of the shape of the assembly. The main member and the connecting member are hollow.

The main member is of long shape. The main member has a base that is wider laterally than its upper portion and an intermediate portion that varies in width between the width of the lower portion and the width of the upper portion. The main members are bounded at each of their longitudinal ends by vertical cotton 16,16 ', said faces being defined vertically and by means of connecting members 17,17'
6 and 16 'each have a generally cylindrical projecting joint element 3, 3'integrally provided. A bottom bridging 12 which allows water to flow laterally is located at the bottom of the member. The bridge 12 is preferably located in the middle of the member and its side wall 13 and its top wall form the lateral reinforcement of the main member.

The top surface of the main member has longitudinal grooves 15 along the entire length of the member. The opening 14 is also provided in the upper part of the member. This opening with the closure device is for charging the component with, for example, water, sand and ballast material.

The height of the connecting member 2 is lower than that of the main member. They have two generally cylindrical bore portions 4,4 'located at both ends of the member over the entire height of the member. These holes are likewise along the sides of the connecting member, the ends 5, 5 of the holes.
Opening through the vertical openings formed between the 5 ', the main member 1 is formed with a groove having a width substantially larger than the lateral thickness of the connecting members 17, 17' connecting the joint parts 3, 3 '.

The joining of two adjoining parts is carried out by the introduction of one joining member between the two main members by vertical sliding, the hole portions 4,4 'of the joining members being the joint elements 3 of the two adjoining main members. It is designed to slide around 3 '.

A holding member which forms the connecting part of the main member and which is arranged, for example, under the end face 16, 16 'of the main member or under the coupling element 3, 3'is, from the ground when the connecting member is put in place. It is held at a distance to allow water to flow laterally. According to a variant of the invention, the retaining members are arranged on the coupling members, for example on their lower or upper surface. The presence of the connecting member makes it possible to carry out the connection of the assembly and the locking of the main member, and the shape of the ends 5, 5'of the connecting member prevents relative lateral displacement of the main member.

Two types of complementary locking members are provided to increase the strength of the assembly and prevent disassembly of the assembly in case of a collision.
They are used in combination or separately. First,
A key 6 with double pins 7,7 'of plastic material, metal material or other strong material is used, the pins 7,7' are holes provided in the central part of the coupling part 3,3 'of the main member. 11,1
It has been introduced to 1 '. Secondly, rods or cables are provided in the main member groove 15 and their length can be a multiple of the sum of the lengths of the main member and the connecting member. These rods or cables may be fitted at each end, for example at the short end with the longitudinal axis of the pin and the eye ring 10.
It is provided with a joint member such as a pin 9 which is bent perpendicular to.
These members can be metallic, plastic or other strong materials. As shown in FIG. 2, the side portions of the connecting members are such that they are joint elements 3 of the main member,
It has a clearance angle and a rounded end which can be an angle adjustment 18 around 3 '. This angle adjustment makes it possible to manufacture curved barriers, for example annular barriers with a diameter of the order of 6 m. Of course, these properties are by no means limiting, and the shape of each member is adapted to the environment, in particular the formation of a safety zone.

Like the main member, the connecting member is adapted to inject ballast. In this case, the opening should preferably be provided on top of the member. This opening is provided with a closure device.

According to a variant of the invention shown in FIG. 3, the coupling member has two parts inclined relative to the joint at an angle of 19 °, so that a curved or small radius safety zone can be formed. Becomes

Either or both of the main member and the connecting member are provided with an anti-slip shoe that enhances adhesion to the ground.

The main and connecting members are made of, for example, polyethylene, PVC or a mixture of glass fibers and resins, or other plastic materials that are centrifugally or injection molded from aluminum or other materials. In one example made of plastic material, the unit length of the main member is 1 m, the wall thickness is 7 mm, and the weight of one member is 1
It is 0 kg. Of course, other sizes may also be implemented depending on the manufacturability and intended use of the barrier assembly.

In the simple case of an assembly, the main member and the connecting member are not loaded with ballast. Therefore, it does not have any openings for this purpose. Similarly, there are no longitudinal grooves 15 on the main member.

Each member of the assembly is manufactured or colored in various colors.
The main member can be red, for example, and the connecting member can be white. Also, for example, the colors of the main members can be changed. Each member of the assembly can be provided with reflective strips or other similar products for nighttime safety.

According to another embodiment of the assembly, not shown, the coupling elements 3, 3'on the main part and the hole parts 4, 4'on the connecting part are arranged horizontally and the mounting of the connecting part in place is lateral. It is carried out from one.

〔The invention's effect〕

The barrier assembly of the present invention comprises a combination of a main member having a projecting portion projecting outward, a bridge having a lower portion, and a connecting member having a hole portion corresponding to the projecting portion. Easy to manufacture and assemble. Also, since water can freely flow laterally through the bridge, all the drawbacks of conventional barriers of this kind can be eliminated.
