The relationship between anchor and prestressed pipe pressure slurry

Prestressed pipe pressure slurry prestressed pipe pulp price good anchorage prestressed pipe pressure slurry manufacturer and connector in front of the home, should be wiped, when should comply with the provisions: 1 pin and the unit installation position should be accurate, prestressed pipe pressure and paste and the channel. The shop is on the whole is placed on suspension, should prevent wrong with seam allowance & # 12539; Install the clip ゲ should make foreign minister basic one. 2 of fruit used for solid type, connect the & # 47196; Lines with the conditions to ensure a check solution during Zhang Hegu can spin and tighten. 5 after the tension reinforcement tensioning and solid line should be the following: prestressed before, prestressed pipe pressure slurry suitable for different types of channel for the less a channel friction test, as determined by testing the x value and Angle used for correction of gauge control stress. See appendix C2 friction loss test method. Tensioning, knot objects or artifacts of coagulation and strength, and modulus of elasticity ( Or age should comply with the regulations of design; And the provisions of the design is not the strength of the concrete should be lower than 80% of design strength grade, elastic modulus should be not less than 80% of 28 d concrete elastic modulus. 3 prestressed tensioning sequence shall meet design requirements; Design not provided, can adopt the method of partial, phased symmetric tensioning prestressed reinforcement shall the whole bunch of tensioning solid radium. Parallel in the flat pipe emissions of prestressed steel wire harness, in ensuring the root steel strand not veiw, can use small tensioning jack by root, but should be considered by the root stress the influence of the tensioning prestress loss of the control. 5 prestressed tensioning side Settings should comply with the regulations of design; Design not provided, it shall meet the following requirements 1) Linear reinforcement and reinforced bar can be tensioned in the end. The curve of the prestressed steel, should be adopted according to the requirement of the construction to calculate the tension or end tensioning manner, when the case of solid loss length less than or equal to the influence of L2 ( L for structure or length) Should be taken when both ends tension; When solid loss is greater than the influence of length L / 2, can be tensioned to end.
