Wire bundle prestressed concrete dome of reinforced concrete structures

摘要

The proposed utility model relates to the field of construction, namely the reinforcing structure prestressing of concrete beams and the method of injection of the reinforcing beam kanaloobrazovatele dome of reinforced concrete structures. The technical result - an increase of quality construction being built at lower complexity of its manufacture and increasing reliability and durability. Valve prestressing of concrete bundle containing a plurality of reinforcing ropes and placed in kanaloobrazovatel dome portion with a locking device mounted on its ends and injection grout node, wherein the locking device is designed as a perforated plate, the number of holes which equals the number of the reinforcing ropes at the beam and is provided with an additional hole with a nozzle located below the rest of the holes to fill the cavity inlet portion kanaloobrazova ator solution with high viscosity, and the outer dimensions exceed the transverse dimension of the plate kanaloobrazovatelya. The perforated plate is made of a material: PCB or getinaks.
