Description
Technical Field
The invention relates to a multi-stair-section stair formwork supporting system, in particular to a supporting vertical pipe structure of the multi-stair-section stair formwork supporting system and an erection method.
Background
Along with the gradual popularization of national large-scale public venue buildings, the height of a single-storey floor is higher and higher, and more stairs with more than two running stairs are designed in the single-storey floor; in order to save space, the whole stair sections are generally designed in the same vertical three-dimensional space, namely, the third stair section is designed right above the first stair section, and the fourth stair section is designed right above the second stair section; in the building body pouring construction, because the floors are integrally poured in a layered manner at one time, all stair sections between the floors also need to be poured at one time, so that the templates of all stair sections between the floors need to be arranged and finished at one time, and the requirement of the integral pouring construction of the floors is met; the erecting of the first bench pouring template and the second bench pouring template of the floor is erected on the finished horizontal floor surface, a traditional erecting method can be adopted, but when the third and fourth bench templates are erected, because the inclined completed templates are erected under the third and fourth bench templates to erect the bench templates without pouring concrete, the bottom supports of the third and fourth bench pouring templates cannot vertically fall to the ground, and the method for erecting the third and fourth bench pouring templates in the prior art is as follows: a third-bench-pouring formwork support system tubular vertical rod is erected on a bottom formwork of the erected first bench, an adjustable jackscrew is arranged at the top end of the third-bench-pouring formwork support system vertical rod and is abutted to a wood ridge through a steel pipe, a third-bench-bottom formwork is arranged on the wood ridge, and the third-bench-formwork and a concrete load are transmitted to the first-bench-bottom formwork through the third-bench-pouring formwork support system tubular vertical rod, and then are transmitted to a horizontal floor through a support system of the first-bench-formwork; the concrete is poured into the whole ladder section at one time, after the concrete of the whole ladder section is solidified and reaches the form removal strength, the ladder section template system is dismantled from top to bottom, because the bottom ends of the vertical rods of the third and fourth ladder section pouring template support systems are supported on the bottom template of the lower ladder section, after the concrete is poured into the ladder section, the bottom ends of the vertical rods are buried in the poured concrete, the bottom ends of the vertical rods of the third and fourth ladder section pouring template support systems can only be cut off by a cutting method, and the vertical rods are taken out and recycled; the method for erecting and dismantling the template leads to the shortening of the upright rods of the supporting steel pipes of the third ladder section and the fourth ladder section, which causes material waste and influences the repeated use of the template; in addition, after the vertical rod is cut, steel pipes and holes which are communicated up and down can be left on the first stair tread and the second stair tread, hole repairing treatment is needed, stress of the stair sections is influenced, and the overall attractiveness of the stair is also influenced.
