Ring beam formwork

Abstract

The invention provides a ring beam formwork which comprises flexible formworks, a plurality of wooden flutes, inner and outer ring binding reinforcing steel bars, inner braces, support bars and draw bars. The flexible formworks comprise a plurality of layers of bamboo plywood, the equidistant wooden flutes are vertically fixedly arranged on the bamboo plywood, and heights of the wooden flutes are predetermined; the flexible formworks are integrally connected with one another by the inner and outer ring binding reinforcing steel bars; the inner braces are fixed to the flexible formworks by reinforcing steel bars, and opposite-pull screws are fixed to the inner and outer ring binding reinforcing steel bars and upright bar binding reinforcing steel bars and are used for supporting the flexible formworks and fixing distances among the flexible formworks; and the support bars comprise upright bars and diagonal braces, and the upright bars and the diagonal braces are fixed together to form right-angled triangles, are fixed to the flexible formworks and jointly support the flexible formworks. The ring beam formwork has the advantages that the ring beam formwork is good in integral surface smoothness effect, convenient to install, wide in application range and good in popularization prospect, a construction period is short, a construction process is reasonable and standard, and the flexible formworks with the bamboo plywood are low in cost.

Description

technical field [0001] The invention relates to the pouring technology of circular and arc-shaped concrete structures, in particular to a ring beam formwork suitable for the construction of large-scale storage tank foundation concrete ring beams. Background technique [0002] The ring beams of large storage tank foundations are usually reinforced concrete ring-shaped thin-walled structures. At present, the ring beam formwork usually adopts a rigid formwork system, that is, a standard shaped steel formwork or wooden formwork is assembled and combined, and it is supported and fixed by steel pipes. Due to the small size of the shaped steel formwork (wooden formwork) and many seams, it is a formwork system that uses polygonal cylinders to fit the arc surface. Therefore, the overall smoothness of the ring beam formwork is poor, and the local axis deviation is difficult to adjust. Construction Time-consuming. However, the use of special large-scale arc-shaped steel formwork, due...
