Formwork system for inverted circular truncated cone-shaped cup opening of column foundation of steel structure factory building and construction method

Abstract

The invention discloses a formwork system for an inverted circular truncated cone-shaped cup opening of a column foundation of a steel structure factory building and a construction method, and belongs to the technical field of design and manufacturing of building engineering construction process equipment. The formwork system for the inverted circular truncated cone-shaped cup opening of the column foundation of the steel structure factory building and the construction method are convenient in construction and capable of effectively guaranteeing the pouring quality of the inverted circular truncated cone-shaped cup opening of the column foundation. The formwork system at least comprises an inner mold blank body comprising a flexible template and a supporting framework, and the flexible template coats the bottom side wall surface and the outer side wall surface of the supporting framework; and in a forming process of the inverted circular truncated cone-shaped cup opening of the column foundation, the inverted circular truncated cone-shaped cup opening is formed by space arranged by an inner mold blank body fixedly supported on a column foundation binding steel bar after a column foundation outer mold is erected. The construction method comprises the steps of designing and manufacturing the formwork system; binding the column foundation steel bar and erecting the column foundation outer mold; installing the inner mold blank body and pouring concrete; dismantling the formwork system after the concrete is initially set and crystallized; and cleaning the formwork system for repeated use next time.

Description

technical field [0001] The invention relates to a formwork system, in particular to a formwork system for a rounded frustum-shaped cup mouth of a column base of a steel structure factory building, and belongs to the technical field of design and manufacture of construction technology equipment for construction engineering. The invention also relates to a construction method for pouring a rounded frustum-shaped cup mouth by using the formwork system. Background technique [0002] In the traditional construction, the rounded frustum-shaped cup mouth of the column base is poured by integrally welding the steel bar and the iron sheet or directly using the formwork method of assembling wooden strips. [0003] When adopting the method of integrally welding steel bars and iron sheets to support the formwork, the formwork must be raised as a whole before the initial setting of the concrete. At this time, the concrete has not yet set up, and the bond between the formwork and the conc...

[0003] When adopting the method of integrally welding steel bars and iron sheets to support the formwork, the formwork must be raised before the initial setting of the concrete. At this time, the concrete has not yet set up, and the bond between the formwork and the concrete during the lifting process can easily lead to the destruc
