Abstract

The invention discloses a cantilever formwork for concrete construction and a construction method thereof, and belongs to the technical field of bridge construction. The problems that construction iscomplicated, cost is high and concrete surface smoothness is low when the outer surfaces of all supporting columns of a bridge are constructed are solved. The cantilever formwork comprises a cantilever formwork support, an anchoring assembly and a planar formwork and is a single-sided wall body climbing formwork used for formwork construction of concrete linings and other structures of dams, piers, concrete retaining walls, tunnels and underground plants, the formwork is easy and rapid to construct and economical, the concrete surface is smooth, the support, the formwork and construction loadsare all borne by an embedded piece assembly, no scaffold needs to be additionally erected, and the formwork is suitable for aloft operation; by means of an anchoring device, the formwork is closely attached to a concrete wall surface, and mortar leakage and slab end faulting are prevented; an inclined strut is arranged on the cantilever support, and the perpendicularity of the formwork can be conveniently adjusted; all connectors are standard, universality is high, and a hanging platform is arranged at the lower portion of the formwork and can be used for assembling and disassembling embeddedpieces and processing the concrete surface.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a cantilever formwork for concrete construction and a construction method thereof. Background technique [0002] With the rapid development of formwork construction of dams, bridge piers, concrete retaining walls, tunnels and concrete linings of underground powerhouses, when the cantilever formwork construction method is used to construct the outer surface of each limb column, our demand for cantilever formwork It also increases accordingly. During the construction process of the outer surface of each limb column, the self-supporting platform starts, that is, the construction starts from the top surface of the platform. Two CB240 cantilever frames are set up, and the frames on each side form a whole working platform, which can be hung and climbed as a whole. All hanging climbing surfaces can be hung and climbed to the top of the pier once installed. [0003] From th...
