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 concrete structures, and specifically relates to a ring beam formwork suitable for the construction of a large-scale storage tank foundation concrete ring beam. Background technique [0002] The foundation ring beam of a large storage tank is usually a reinforced concrete ring-shaped thin-walled structure. Ring beam formwork currently usually adopts a rigid formwork system, that is, the use of standard shaped steel formwork or wooden formwork assembling combination, and fixed with steel pipe type frame rod support. Due to the small size of the shaped steel mold (wood mold) and the large number of joints, it is a formwork system that uses polygonal columns to fit the arc surface. Therefore, the overall roundness of the ring beam formwork is poor, and the local axis deviation is not easy to adjust. Time-consuming. However, the use of special large-scale circular arc steel formwork, due to t...
