Outer decorating layer formwork for conical columns of comprehensive gym and construction method of outer decorating layer formwork

Abstract

The invention relates to a device for casting cast-in-place concrete, in particular to an outer decorating layer formwork for conical columns of a comprehensive gym and a construction method of the outer decorating layer formwork. The outer decorating layer formwork is positioned on the outer side of an outer decorating layer and comprises a face board, back ribs and oppositely-pulling screws, the face board is a bilayer thick wood formwork, a three-ply board is lined on one face, facing the decorating layer, of the face board, and one ends of the oppositely-pulling screws are anchored on conical concrete columns to fix the face board and the back ribs. The construction method includes the following steps: rechecking structural size of cast conical columns; determining a formwork machining detailed drawing; making and assembling the formwork; trepanning for bolts of the formwork; putting the formwork in place for the first time; trepanning structural columns along reserved bolt holes of the formwork; retreating the formwork; implanting sectional screws; putting the formwork for the second time; demounting the formwork. A wood formwork face board and a section steel keel are matched mutually, so that the outer decorating layer formwork is easy to assemble and suitable for structural components variable in shape, and forming effect of the components meets designing requirements under the condition of reasonable and effective reinforcing and supporting.

Description

technical field [0001] The invention relates to a device for pouring in-situ concrete, in particular to a template for the external decorative layer of a tapered column in a comprehensive gymnasium and a construction method thereof. Background technique [0002] Faced with special-shaped components in tall and large spaces, professional formwork manufacturers are often selected to design and produce shaped formwork, such as shaped steel formwork. The advantages of professional formwork design are more accurate formwork system, stable structure, and more convenient construction, but the project cost is higher. At the same time The stereotyped formwork also has its limitations. When encountering irregular structural components, it cannot be mechanized on the production line. It is very difficult to produce professional formwork and cannot solve the problem. In addition, the production cycle of the stereotyped formwork is long. It takes a certain period of time, and the non-rep...

[0002] Faced with special-shaped components in tall and large spaces, professional formwork manufacturers are often selected to design and produce shaped formwork, such as shaped steel formwork.

At the same time The stereotyped formwork also has its limitations. When encountering irregular structural components, it cannot be mechanized on the production line. It is very difficult to produce professional formwork and cannot solve the problem. In addition, the production cycle of the stereotyped formwork is long. Occupies a certain period of time, and the non-repeatability of the finalized template will also cause waste of data
