Prestressed pipe pressure slurry meet first put piece of tensioning prestressed concrete

Prestressed pipe pressure slurry prestressed pipe pressure prestressed pipe pressure slurry paste manufacturer price first put piece of prestressed tensioning prestressed pipe pressure slurry shall meet the following requirements 1 stress steel put zhang component of concrete strength and elastic modulus ( Or age) Not provided, shall comply with the design requirements: design should not less than the design strength grade of concrete strength value of 80%, pulp elastic modulus of prestressed pipe pressure should be not less than 80% of 28 d concrete elastic modulus. 2 in front of the prestressed reinforcement put before, should be restricted within the side form, flange template or displacement mode removed. 3 play a sequence of prestressed reinforcement should comply with the regulations of design; And the provisions of the design is not in every stage, uniform, symmetry, crisscross put piece of each other. More than 4 batch put piece of prestressed reinforcement, when using sand box to put zhang, put sand rate should be uniform; Adopt jack put zhang, put Zhang Yi fractional complete; Single reinforced with the method of screw nut put zhang, should be on both sides before the middle, and shall not be a will finish a tendon loose. Put a protracted war, 5 prestressed for steel wire and steel wire, prestressed pipe pressure slurry should adopt the way of mechanical cutting to cut off; Can be used for reinforced bar, acetylene oxygen cutting, but should take the necessary measures to prevent the high temperature impact on it. 6 long term pedestal of prestressed reinforcement to cut off the order, shall be put Zhang Duan began, in turn to the other end cut off.
