5) by anchor slab in the leveling of nonmetal leveling nut;
6) colligation reinforcement foundation build mixed earth, by upper anchor slab, lower anchor slab and anchor pole are cast in concrete foundation, after concrete reaches prescribed strength by the time, after hanging on bottom column cylinder, stretching anchor rod on upper anchor slab.
The replacing construction method of the removable prestressed bolt composite member that the utility model provides, comprises the following steps:
1) the first half of fracture crab-bolt is first extracted;
2) then bore with tapping screw thread the rupture cross section aimed at and pierce fracture crab-bolt; Drive the latter half of fracture crab-bolt and screw thread to reversely rotate while screw thread pierces, after making fracture crab-bolt automatically exit lower nut, together extract from the bolt hole on upper anchor slab together with tapping screw thread drill bit and fracture crab-bolt; Or the sleeve adopting end to be provided with claw will rupture crab-bolt taking-up;
3) insert new anchor pole from the bolt hole of upper anchor slab, at rotary-top anchor pole, make to be screwed into lower nut bottom it, after the bottom column cylinder place then above upper anchor slab installs new pad and nut successively, stretching anchor rod.
Compared to the prior art the utility model has following beneficial effect:
The removable prestressed bolt composite member that the utility model provides, reasonable in design, after concrete foundation completes or after fan operation, still freely can change every root crab-bolt, avoid using the disruptive methods such as excavation of foundation pit to change crab-bolt to the impact of basic stress.Can save a large amount of man power and materials, replacement cost is low, and efficiency is high.
The construction installation method of the removable prestressed bolt composite member that the utility model provides, workable, operating efficiency is high, easy construction.
The replacing construction method of the removable prestressed bolt composite member that the utility model provides, workable, operating efficiency is high, can save a large amount of man power and materials, reduce costs, and improves and changes efficiency, can overcome many deficiencies of prior art.
