Prestressed pipe pressure slurry for prestressed concrete construction requirements

Prestressed pipe pressure slurry prestressed pipe pulp price prestressed pipe pressure prestressed pipe pressure slurry paste manufacturer for prestressed concrete prestress, shall meet the following requirements: 1 jack Ann stroke should be at the front of the work is right and wrong, work with dislocation of the each shall not be, but C when tensioning, the center of the mouth with surface の trace で quantity を デ on the same axis. & lt; 跨度。 。 。 2 prestressed stress should be operator sequence and ball control rules. When the construction of prestressed pipe pressure slurry to prestressed ShiChao tensioning are included in the trace circle mouth should be losses can be set beforehand cuckoo increased by 5%, what circumstances are not. Prestressed stress system with 3 zhang, should be a long line to check. Zero international sinking value and the difference of the theoretical elongation value meter (now Of the force on the snow should stop to exceed the maximum tension control of design should be が pull, and take measures to adjust and shown to ascertain the original countries may continue to tension/radius of curvature on annular brain, u-shaped tendons, etc the & # 12539; Four of the prestressed steel bucket flat theoretical elongation value ( C) Meter/PL ( 7. 6. 3 - 1) Type: P that the average tension should be reinforced in advance, N) The tension of the tension, linear reinforcement, On both ends of the curve of the tensioning tendons, see this specification appendix E analysis C1L prestressed reinforcement length (one by one m） ; A, the sectional drawing of A prestressed product ( m） One prestressed concrete elastic modulus (E Nmn） 5 tensioning prestressed reinforcement, the prestressed pipe pressure slurry should be adjusted to the initial stress, the stress appropriate for tension control stress at the beginning of sigma. 0% - 25%, the elongation value should be start when the initial stress measurement. Prestressed reinforcement of the actual elongation value in addition to the measurement of the elongation value, it is should be combined with initial stress calculation under the elongation value. The prestressed tensioning delta L (the actual elongation value mm） 32) Computing: delta, L = 1 + delta L2 (delta 7. 6. 3 - 2) Type: delta ム ー from initial stress and the maximum tension stress between the measured elongation ( m） Delta L2 initial stress calculation under the elongation value ( m） , can use elongation value of the adjacent level. Laying the solid of 6 prestressed concrete and prestressed slurry pipeline pressure should be under tension control stress in a stable state.
