Chimney formwork turning construction device

Abstract

The invention discloses a chimney formwork turning construction device. According to the technical scheme, the chimney formwork turning construction device is characterized in that the device comprises an operation platform, a lifting device for driving the operation platform to move upwards, at least two layers of inner formworks arranged on the inner wall of a chimney in a surrounding mode, and at least two layers of outer formworks arranged on the outer wall of the chimney in a surrounding mode; an annular casting cavity is defined by the inner formworks and the outer formworks; the inner formworks and the outer formworks are arranged in the vertical direction; fixing devices are arranged between the outer formworks and the inner formworks; and a hanging racket for allowing constructors to assemble or disassemble the inner formworks and the outer formworks is arranged below the operation platform. In the construction process, steel bars are bundled at first, the inner formworks and the outer formworks are assembled and fixed on the top of the chimney subjected to casting molding, an operator injects concrete into the casting cavity on the operation platform, the operation platform is lifted after the concrete is shaped, the steel bars continue to be bundled, then the inner formwork and the outer formwork on the lowermost portion are detached and installed to the position below the operation platform, another new casting cavity is formed, and the operations are conducted repeatedly till the required casting height is achieved.

Description

technical field [0001] The invention relates to a building construction device, more specifically, it relates to a chimney turning form construction device. Background technique [0002] The reinforced concrete chimney in the electric power construction project is a towering structure and a landmark building of the whole power plant project. In the chimney construction process, the vertical transportation of the reinforced concrete chimney construction is the main process in the whole construction, and the vertical transportation is mostly solved by the sliding form construction technology. [0003] With the improvement of environmental protection awareness in the whole society, the sliding form construction is to directly slide the formwork for construction. When pouring and forming a layer of lifting formwork, the thrust provided by the oil cylinder is used to force the formwork to move upward, so that the formwork and the surface of the chimney slide relative to each othe...

Problems solved by technology

[0003] With the improvement of environmental protection awareness in the whole society, the sliding form construction is to directly slide the formwork for construction. When pouring and forming a layer of lifting formwork, the thrust provided by the oil cylinder is used to force the formwork to move upward, so that the formwork and the surface of the chimney slide relative to each other. However, due to the great friction between the formwork and the chimney

Therefore, the sliding form construction method is prone to produce common quality problems such as pockmarks and cracks on the surface of the chimney
