In the reversed construction method of above-mentioned building, best, according to following contrary when carrying out the construction of substructure as mode, every layer floor adopts close girt strip, and the common formation of its diaphragm wall with the outside plays the bigger horizontal support system of rigidity of stabilization to compound pile.According to this mode, can not increase under the condition of cost, obtain bigger horizontal rigidity.
In the reversed construction method of above-mentioned building, best, when the construction of the above-mentioned stake that has load dish and/or a branch, ground around it is carried out churning handle, thereby realize the churning ground and have the stake or the common bearing load of pile group of load dish and/or branch.According to this mode, can realize the stressed jointly of stake soil, and then can bear bigger upper load.
In the reversed construction method of above-mentioned building, best, above-mentioned rigid column is a steel tube concrete superposed column.When adopting steel tube concrete superposed column, because the vertical bearing capacity of this steel tube concrete superposed column is big especially, so be particularly suitable for making high-rise building.
In the reversed construction method of above-mentioned building, best, above-mentioned steel tube concrete superposed column is to make like this, and steel pipe is installed, and will manage the bottom and be connected with the stake top; Make high-strength concrete column core in the pipe; Outside steel pipe, make reinforcing cage; Outside steel pipe, fluid concrete.
In the adverse construction method method of above-mentioned building, best, during combine of the top of the bottom of steel tube concrete superposed column and the stake that has load dish and/or branch constructed, when laying steel column, at the place, aperture adjustable aperture is set instrument is installed, be beneficial to the adjustment of the level and the vertical direction of steel column.
In the adverse construction method method of above-mentioned building, best, above-mentioned rigid column is lattice column or shaped steel.When adopting lattice column, can be suitable for the partial structurtes structure, such as, the requirement of elevator shaft.
