Abstract

The invention discloses a large arc-shaped steel mold with adjustable width. The arc-shaped large steel mold is partially provided with drawers between two adjacent steel mold segments. The arc-shaped steel mold segments are connected to each other in an elliptical arc shape; the drawers are evenly distributed between two adjacent steel mold segments. The present invention divides the whole large steel mold into several arc segments, and according to the requirement of the length of the arc wall with variable cross-section, drawers are arranged at intervals between the arc segments, and only need to remove corresponding The drawing strip can adapt to the needs of the new arc wall.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to an adjustable-width arc-shaped large steel form suitable for variable-section arc-shaped walls. Background technique [0002] At present, the formwork used for the arc-shaped wall with variable cross-section in the project mainly adopts the following three methods: on-site configuration of wooden formwork, custom-made circular arc-shaped small steel formwork, and custom-made fixed circular-arc-shaped large steel formwork. [0003] The construction process of configuring wooden formwork on site: nine plywood → horizontal purlins adopt steel bars or steel pipes with arcs → vertical purlins adopt steel pipes. Its advantages are low single investment cost, flexible application to various structural shapes, and good plasticity. Its disadvantages are that the apparent quality of the concrete is poor after forming, it is easy to wear and tear, the reuse rate is low, and...
