Two pass joints are inserted, set thickness even closer to connect for 10mm valve rubber between support holes and two pass joints, side branch
The a diameter of 35mm of point pre-stressed strutses.The steel anchoring hoop coupled with side fulcrum pre-stressed strutses bottom is arranged on concrete floor
Lower section 450~550mm positions, steel anchors garter spring and arranged around brick wall, and steel anchoring hoop cross sectional shape is square, composition steel anchoring hoop
Steel plate thickness be 15~18mm, width be 100~120mm.Be respectively provided with tensioning bolt in the middle part of pre-stressed strutses, tensioning bolt with
Bottom pre-stressed strutses are affixed, and tensioning bolt is screwed connection with top pre-stressed strutses, and pre-stressed strutses side is installed should
Power meter measures stress data during prestressed stretch-draw, turn tensioning bolt during prestressed stretch-draw, so as to drive pre-stressed strutses
Tensioning.
The utility model safe operation is reliable, and structural behaviour is good.
