Abstract

The invention discloses a prefabricated box girder mold with adjustable curvature radius and an installation and construction method of the mold. The invention adopts the concept of replacing the curved line with a folded line of a fixed length, and accurately sets out the bottom mold, so that the side mold is designed by It is composed of several fixed-length fixed sections. An elastic change section is set between the fixed-length fixed sections, and an adjustment link rod is set between the fixed-length fixed sections to realize the function of adjusting the curvature of the fixed-length broken line. At the same time, the adjustment insert section is embedded in the side mold The adjustment of inner and outer arc length changes can not only meet the needs of fixed section and variable curvature prefabricated building components, but also meet the production or construction needs of continuous variable section and variable curvature prefabricated building components. The prefabricated box girder mold with adjustable curvature radius of the present invention can not only meet the overall needs and accuracy requirements of the design curvature change, but also has a smooth and beautiful surface, with as few or no traces of template joints as possible.

Description

technical field [0001] The invention relates to the field of concrete prefabricated building component products in municipal construction. Specifically, it relates to an adjustable radius of curvature mold for prefabricated concrete building components, especially prefabricated box girders, which is suitable for box girders whose main surfaces on both sides are vertical straight lines and whose section conditions are continuously changing or fixed. ; The present invention also relates to a construction method for box girder prefabrication using the mold. Background technique [0002] With the needs of modern municipal construction, in construction projects such as elevated road box girders, bridge deck girders, and track girders (rail transit), various types of large curvature (small radius) and variable (radius) curvature curved beams, plates, etc. , will be widely used in various municipal construction projects. In particular, the curved beam with variable (radius) curva...
