The invention provides a device for easily demoulding concrete form and a demoulding method, belonging to the field of architectural construction. The device comprising a form board, a fixed plate with a threaded rod and a six point sleeve with internal and external threads; wherein, the internal surface of the end part of the sleeve is sealed with the surface of the form board by an alkali-resisting O-shaped seal ring; the sleeve penetrates through the hole of the form board, is fixed by a nut out of the form board in a way that passing through a carrier ring, and forms a hexagonal structureon the end part; and the fixed plate with the threaded rod and the sleeve with the internal and external threads are connected in a sealing way by screw thread thereof. After the concrete reaches to demoulding intensity, twisting the sleeve, the form board relatively moves to the concrete so as to be separated, and the bolt connection set is dissembled from the form board so as to be used at the next time. The form board does not need to be coated with separant, therefore, the invention is free of noise and dust pollution, has simple structure, strong popularity and convenient operation, is safe and reliable, has fast demoulding speed, improves demoulding work efficiency, reduces labor intensity of workers, prolongs the service life of form board and heightens the appearance quality of the concrete. The device can achieve good social benefit, economic benefit and environmental benefit.
Description
Easy-to-detach concrete formwork device and formwork release method technical field The invention relates to a building construction tool and method, in particular to an easy-detachable concrete formwork device and a demoulding method. Background technique During the construction of cast-in-place concrete structures, the removal of formwork is labor-intensive, resulting in noise pollution and dust pollution, high risk, and low work efficiency, which has always plagued construction enterprise managers and construction personnel. The traditional form removal method is: first hammer the wedge along the junction of the concrete and the formwork (the bottom formwork of the cast-in-place floor slab needs to destroy a formwork first), and then use a crowbar to forcibly remove the formwork. This method not only causes serious damage to the formwork, greatly reduces the service life of the formwork, but also causes the cast-in-place concrete structure to lack edges and corners, whi...
