Concrete structure casting framework and segmented casting method

Abstract

The invention discloses a concrete structure casting framework and a segmented casting method. The concrete structure casting framework comprises an inner form board and an outer formwork, wherein theouter formwork is formed by connecting a first formwork with a second formwork by bolts; and the first formwork and the second formwork are in mirror symmetry. In the invention, the amount of misalignment between an inner frame body and an outer frame body is changed, the inner form board is alternately supported by a first hydraulic supporting mechanism and a second hydraulic supporting mechanism of the outer frame body or a third hydraulic supporting mechanism and a fourth hydraulic supporting mechanism of the inner frame body, and the inner form board is alternately fixed by an extrusion block connected to an end of a first MYT3-23 hydraulic pusher or a supporting and sliding mechanism connected to a second MYT3-23 hydraulic pusher, thus, combination of lifting of the whole casting framework is realized, form establishment and casting of the casting framework to a gravity pier are realized, the construction period is shortened, and meanwhile, the labor intensity and the labor costfor construction of the casting framework are reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete structure pouring frame and a segmented pouring method. Background technique [0002] Gravity piers, also called solid piers, are solid masonry piers, which mainly rely on their own gravity to balance external forces, thereby ensuring the strength and stability of the pier. It consists of a solid structure, and can be divided into solid gravity piers and solid light piers according to its cross-sectional size and weight. This kind of bridge pier has high rigidity and strong anti-collision ability, but at the same time, it has the defect of large water blocking area, so it is more suitable for building on foundations with high foundation bearing capacity, thin covering layer, and shallow bedrock buried depth . [0003] At present, the pouring of gravity bridge piers adopts the segmented pouring method. The entire pouring process is to pour a section unti...

AI Technical Summary

Problems solved by technology

[0003] At present, the pouring of gravity piers adopts a segmented pouring method. The entire pouring process is to pour a section until the concrete has solidified to a specified strength before a new pouring frame can be built. After that, the previous pouring frame needs to be disassembled, so that the whole The construction period of gravity bridge piers is longer and the labor cost is higher
