What is the order of demolition of cast-in-place components of the template

The general procedure of dismantling the template is: first dismantle after supporting, dismantle after supporting; first dismantle the non-load-bearing part, then dismantle the load-bearing part, and make sure not to damage the member or template. For the dismantling of beam and plate template of tool-type supporting mold, it should first dismantle the clamps, square logs and side boards, and then loosen the wooden wedges to make the pillars and trusses descend, and then pull out the bottom template and horizontal blocking logs one by one, and finally take down the trusses and pillars. For the demolition of side plate supported by fixed combination steel mold plate, the nuts of tensile bolts and hook bolts and steel flutes should be removed first, and the U-type card on the template should be removed, and then the plate should be dismantled piece by piece from the top to the bottom. For the demolition of columns, beams and slabs of frame structure, the column template should be removed first, then the silk stalk lifter on the supporting upright should be loosened to make the purlins supporting the cross flute of beams and slabs descend smoothly, and then the beam side boards and platform boards should be demolished, the beam bottom boards should be withdrawn, and finally the cross flute, the beam rubbing strip, the column linkage and the column should be taken down.

For the use of pull-out as well as downward molding method of construction of assembled large boards should be examined body demolition, demolition to prevent damage to the template and concrete. For arches, thin shells, round curved roofs and beam structures with spans greater than 8 meters, appropriate methods should be taken to make the formwork supports uniformly relaxed to avoid harmful stresses on any part of the structure when the concrete is disengaged from the floor slab. When removing the formwork of round roofs and funnel-shaped simple bins, it should be allowed to start from the bracket at the center of the structure and remove it to the periphery of the structure in a symmetrical form of concentric levels. Before removing the formwork of arches with ties, the ties shall be tightened. In the process of dismantling the formwork, if it is found that there are large voids, interlayers and cracks in the concrete, which affect the structure or components according to the quality problems, the dismantling shall be suspended and can only be continued after studying and dealing with the relevant departments. The structure of the dismantled formwork and its support should be allowed to bear the full calculated load only after the concrete strength reaches the design standard. When the construction load is greater than the design load of the structure, it must be accounted for and set up temporary support to be reinforced.
