Prestressing reinforcement in concrete structures are widely used in construction. It is fitting that a working design before concreting special jacks or pull on an electrothermal method and taut produce concreting. After hardening and curing of concrete and its acquisition of the necessary strength tension reinforcement is removed, this fixture tends to occupy its original position, hand over some [...]
In reinforced concrete reinforcement steel bars called various sections and shapes (round, square, rectangular, oval), steel ropes and strands, tensile and shearing perceive stresses in the concrete elements of the external loads and dead weight of structures. Valves may be of constant cross section (plain bars) and the periodic profile. On the complexity of manufacturing valves with a diameter of 12 mm rods called [...]
Wood and plywood formwork elements and their supporting timber forest produce efficiently in woodworking shops shuttering plants. For small volumes of work and distance of objects from the central workshops of wooden formwork can be made on-site formwork at the workshops. For proper assembly and disassembly of formwork the latter is marked. Opalubschiki work on the Marking Act or installation drawings, consisting of the construction plan [...]
Concrete and reinforced concrete structures are classified at present for monolithic and prefabricated. Monolithic reinforced concrete structures are being built directly during construction rabotpri construction of the building or structure, teams are made on separate plants or landfills, and are mounted directly on the site. Widespread use of prefabricated structures is a basic condition of industrialization of construction, the transformation of the site in the mounting. However, along with increased production of [...]
