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

Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] Such as figure 1 and figure 2 As shown, the present invention provides a multi-segment curved auditorium concrete ladder formwork device in a theater, which mainly includes: a formwork support frame body 1 and a formwork 2 .

[0038] The formwork supporting frame body 1 adopts fastener type steel pipe scaffolding, which mainly includes: horizontal member 11, vertical member 12, horizontal positioning steel pipe 13, vertical rod 14 and tension screw 15. The horizontal component 11 includes a horizontal main joist 111 and a horizontal sub-keel 112 , and the vertical component 12 includes a vertical main joist 121 and a vertical sub-keel 122 .

[0039] Especially as figure 2 As shown, the formwork 2 mainly includes: an outer formwork 21 for defining the outside of the steps and the height of the steps, an inner formwork 22 for defining the inside of the steps, and ...

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...
