Road sign

The utility model relates to traffic management, in particular to one-way traffic signs.

A well-known road sign containing a knowledge sign with the information field Sem applied on it, GOST 10807-78 Road signs M. Gosstandart of the USSR, 1979, p. O). Known sign can be made both one-sided and two-sided. The shield base of this sign is made of an anticorrosive material, for example aluminum, or of a steel base with a protective coating. The information field is made of reflective material.

The disadvantages of the known signs is their high cost. In addition, in the case of using an aluminum base, it is necessary to expend strategic raw materials, and in the case of using a steel base, the signs have a large mass and more complicated manufacturing technology, caused by the need for additional application of an anti-corrosion coating.

The authors were faced with the task of reducing the cost while maintaining the technical requirements for road signs.

The problem is solved in that in a road sign containing a base plate and an information field applied to it, the base plate is made of wood-pressed mass.

The implementation of the base plate of the wood pressing mass allows to reduce the manufacturing cost to 30, while all the technical requirements for road signs are observed. In addition, compared with road signs on a steel base, the weight of the sign is reduced by 20-25 and there is no need for anti-corrosion coating , and compared with signs based on aluminum, the claimed solution allows you to replace expensive strategic raw materials with material obtained from waste.

The structural essence is illustrated by drawings, which show:

Fig.8 is a section aa of Fig.7.

The one-way road sign contains a base plate I, on the front surface of which with the help of glue of the brand ШК iViPTy 38-5-880-66 the information field 2 is made of hemp. The reverse surface of the shield I has stiffening ribs 3 with fixing holes 4 made on them. The base shield is made by pressing wood pulp according to GOST 11368-89 grades LSCHP or MDPO containing wood filler (for example, particles of birch veneer, shavings or sawdust of hardwood) and a binder (e.g. bakelite varnishes or water soluble phenol-formaldehyde resins). The technological process of pressing does not differ from traditional direct pressing and includes filling the press material into the mold matrix, holding it for 8 minutes in the mold under a pressure of about IOC kgf / cm at a temperature of 130 - and then removing the finished plate - bases After that, if necessary, the strip is stripped from the finished product. Then an information field is poured onto the pressed plate. The finished product meets the strength and operational requirements of the road: vI signs. The sign can be operated both attached to a rigid support, and in a suspended version, and can also be made one-sided and two-sided. In the latter case, a simple combination of two one-sided signs is carried out. ,:
