Concrete ladder formwork device and construction method for multi-segment curved auditorium in theater

Abstract

The invention provides a formwork device of a theater multi-section-curve auditorium concrete stairway and a construction method for the theater multi-section-curve auditorium concrete stairway. The device comprises formworks and formwork supporting frame body used for supporting the formworks, the formworks comprise the outer side formworks used for limiting the outer side of the stairway, each two adjacent outer side formworks are mutually connected through a dorsal bar, the distance between each two dorsal bars is adjusted through at least one adjusting threaded rod, and then the radians of the outer side formworks are further adjusted. According to the formwork device of the theater multi-section-curve auditorium concrete stairway and the construction method for the theater multi-section-curve auditorium concrete stairway, not only is the constructional difficulty reduced, but also the frameworks are saved, the curve curvature of the curve stairway can be controlled accurately, the pouring quality of concrete is enhanced, therefore the construction quality of whole curves is ensured, and follow-up repairing work is not needed.

Description

technical field [0001] The invention relates to the field of construction, in particular to a multi-segment curved auditorium concrete ladder formwork device for a theater and a construction method thereof. Background technique [0002] With the development of social economy, people's demand for spiritual culture is getting higher and higher. In recent years, more and more theaters have appeared in cities. Due to the particularity of the theater itself, the design of its auditorium must meet the needs of the audience's perspective. Therefore, the curved and stepped seat layout is essential, which greatly increases the difficulty of construction. At present, for the construction technology of the concrete steps of the multi-segment curved auditorium in the theater, loose formwork is often used to complete the installation of the curved formwork. [0003] However, the construction of the concrete steps of the theater's multi-segment curved auditorium uses loose formwork for t...

AI Technical Summary

Problems solved by technology

[0003] However, the construction of the concrete steps of the multi-segment curved auditorium in the theater uses loose formwork for the processing and installation of the formwork, which has the disadvantages of difficult material processing, waste of formwork, and difficulty in guaranteeing the arc curvature of the curved steps.

Therefore, in order to ensure the overall curve construction quality, a lot of chiseling and repair work is often required in the later stage, which undoubtedly increases the labor load and economic cost of workers
