Step 12: removing the templates, wherein the removing sequence is that the non-bearing templates on the side surfaces are removed firstly when the templates are removed, then the bearing templates are removed, and the removing sequence and the safety measures of the templates and the supporting system thereof are strictly in accordance with the special construction scheme of the basement template; the time for removing the formwork is specified as that the concrete strength when the formwork and the support are removed is in accordance with the requirements of the existing national standard GB50204 of the acceptance standard for the construction quality of concrete structural engineering, the design is randomly timed for the formwork removal time, and the formwork can be removed after the compressive strength of the cured test block under the same conditions reaches the following requirements: the compression strength of the concrete reaches 2.5MPa, the non-bearing side mold can be disassembled when the surface and the edges and corners of the concrete are not damaged due to mold removal, under the general condition, the wall mold and the column mold can be disassembled 12-24 hours after the concrete is poured, the strength of the concrete reaches 50% of the design value, and when the distance between the support rods is less than or equal to 2m, the bottom mold can be disassembled, under the general condition, the beam bottom mold and the plate bottom mold can be disassembled 36-48 hours after the concrete is poured; the method for removing the formwork includes the steps that the wall column formwork removal can be carried out simultaneously with the formwork lowering at the position of a slab, pins are taken down after diagonal braces and back ridges are removed, a special formwork removing tool is used for slightly prying and loosening the whole wall formwork, then wall formworks are sequentially removed from the position of an external corner, a beam bottom formwork at an internal corner is removed after the beam bottom internal corner formwork is removed, the rest beam bottom formworks are sequentially removed, a beam side formwork is removed after the beam bottom formwork is removed, the beam side formwork is removed, the floor internal corner formwork is removed after a beam side formwork and the wall column formwork are removed, the floor internal corner formwork and the floor formwork at the position are removed, the rest floor formworks are removed, the construction safety and the formwork protection are taken care during the floor formwork removal, the removed formwork cannot fall freely, and the formwork removal is required to be carried out early, the supporting system of the part is strictly prohibited from being disturbed, the vertical support is strictly prohibited to be supported for the second time after being detached along with the template, the supporting rod is always in a load bearing state, and the conversion of structural load transmission is reliable.
Step 13: dismantling the supporting vertical rods, specifically, when the strength of the concrete member contacted with each formwork reaches 50% -100% of a design value, dismantling a part of the supporting vertical rods by the concrete member, and ensuring that the rest supporting vertical rods are uniformly distributed and the distance between two adjacent supporting vertical rods is less than 2 m; when the strength of the concrete member contacted with each template reaches 100% of a design value, removing the rest of the supporting upright rods; the support upright rod is detached only by knocking loose the adjustable base of the support rod by a hammer and then taking down the support rod; therefore, the turnover of the vertical rod can be improved, and the cost is reduced.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
