  • Page 12 KSP SHAFT PLATFORM 3.1.2. Walers positioning Once the brackets are assembled on the walers, the next operation consists of positioning the walers. In order to do it properly, some timber planks should be used to support the set, preventing the Gravity pawl from touching the floor.

  • Page 13: Main Platform Performance

    KSP SHAFT PLATFORM It is recommended to adjust the board taking into account that the distance from its edge to the wall will be approximately 50mm. These chains are directly fixed on the waler by a E20x70 pin (this pin will be an extra pin different to the ones used to fix the Gravity pawl bracket).
  • Page 14 KSP SHAFT PLATFORM 3.2.1. GP Box Out: To be able to insert the main platform into the shaft, pawl brackets have to be previously folded. The best way is to tie the mobile part of the pawl to the waler using cords.

Folding bracket After the first pouring formwork panels are stripped off; the Folding Bracket can be fixed to these cones embedded in the concrete wall with an M24x80 bolt. Once the Folding brackets are fixed to the cones in the wall and as they stand out of the wall, the main platform can be inserted in the shaft and left resting through the Adjustable brackets of the platform on...
  • Page 16 KSP SHAFT PLATFORM There are three different connection types between main platform and cone recovery platform: • Connection by BRIO standards • Connection by push-pull props E • Connection by DW15 tie rods • Connection by BRIO standards: BRIO HEAD/DU and BRIO scaffolding standards are In these cases the best option is to preassemble BRIO used for this solution: HEAD/DU on the main and cone recovery platforms.

To do so, a 18mm hole has to be drilled through the plywood. This part remains in the concrete and only removing the short pin 0,35m and stripping the formwork a few millimetres from the wall, the formwork set can be...
