Y-type cast-in-place concrete column formwork system and construction method thereof

Abstract

The invention discloses a Y-type cast-in-place concrete column formwork system. The formwork system is composed of a column root formwork system, a column handle formwork system and a branch column formwork system and comprises multi-layer plates, back edges, column hoops, split bolts, diagonal supporting rods, diagonal pull rods, horizontal pull rods and the like, and all the components are connected to form a whole to be fixedly supported on a floor slab or a plain concrete pier. The invention further discloses a construction method for the Y-type cast-in-place concrete column formwork system. The construction method includes the steps of model designing, sample machining, formwork manufacturing, hoisting, formwork and support reinforcing, positioning control and precision adjusting; when a formwork is installed at the proper position, construction of the column root formwork system is carried out first, then construction of the column handle formwork system is carried out and ultimately construction of the branch column formwork system is carried out. Y-type positioning control is facilitated due to the fact that corner angles are reserved; a wood formwork system is easy to splice and is suitable for structural components with various models, the forming effect of the components meets design requirements, and the manufacturing cost of the wood formwork system is low.

Description

technical field [0001] The invention relates to a cast-in-place concrete pouring device, in particular to a Y-shaped cast-in-place concrete column formwork system 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-repeatability of the finalized templat...

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
