On the type reinforced concrete beams divide on base, rafter, subcrane and beams of overlappings.
Rafter reinforced concrete beams can have various form. Allocate odnoskatny, duo-pitch trellised, duo-pitch continuous and beams with a horizontal belt.
Reinforced concrete beams can have rectangular, tavrovy, double-T, trapezoid or hollow section.
The manufacturing techniques of beams are defined by type of cross section. The most widespread is the monolithic or combined and monolithic way of production of beams. At a monolithic way of a beam produce directly on a building site. The combined and monolithic method provides production of beams at plant. The way of production of reinforced concrete beams defines the choice of concrete, fittings and a timbering.
Application in construction of combined beams allows to reduce considerably labor costs while monolithic designs have the increased efficiency and durability.
The production technology of reinforced concrete beams is constantly improved. First of all it concerns use of polimerbeton, transferring of the main technological processes on the level of factory production, automation of processes of preparation of concrete mixes, use of hi-tech softeners, new techniques of heat treatment and modern antifrosty additives.
Production of reinforced concrete beams provides application of rather difficult technological process including assembly of a timbering, installation of frameworks of fittings, supply of concrete mix, laying of concrete and its consolidation, special care of concrete at its hardening and dismantle of a timbering.
The so-called inventory timbering providing repeated use is usually applied to production of beams. As material for a timbering use a tree, metal and even reinforced concrete.
Modern technologies allow to receive high-quality reinforced concrete beams which will have quite acceptable cost.
