Construction H type Door type scaffolding installation and dismantling should be carried out in a certain order. Some people think that the installation needs to be carried out in order, and dismantling does not matter, just demolition can be, in fact, it is not. Scaffolding dismantling is also required to speak of the order, only to master the order of dismantling scaffolding to achieve twice the result with half the effort.

   (1) from the span side first remove the top handrail and railing column, then remove the scaffold plate (or horizontal frame) and escalator section, and then remove the horizontal rod reinforcement rod and scissor brace.
   (2) from the top span side to start demolition cross support, synchronous demolition of the top support with the wall rod and the top floor door frame.
   (3) Continue to phase down the synchronous dismantling of the second step gantry and accessories. The free cantilever height of the scaffold shall not exceed three steps, otherwise temporary ties shall be added.
   (4) Continuous synchronous downward dismantling. For the wall rod, long horizontal rod, scissor brace, must be dismantled after the scaffold is dismantled to the relevant span gantry, then can be removed.
   (5) Dismantle the floor sweeping bars, bottom gantry and sealing bars.
   (6) Dismantle the base, and transport the mat and mat block.
