Description

Technical Field

[0002] Box girder is a type of beam and slab in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. Prefabricated box girders are a commonly used form of upper structure in bridge engineering. Prefabricated box girders are generally prefabricated in prefabricated beam yards. Before processing prefabricated box girders, the pedestal is first set up, and then the steel skeleton, corrugated pipe, inner mold, outer mold and end mold are installed, and finally the concrete is poured. After the concrete is cured and formed, the end mold, outer mold and inner mold are removed in turn, and the prestressed tendons are threaded through the concrete and the prestressed tendons embedded in it are tensioned. After the tensioning is completed, grouting and curing are carried out in the prestressed tendon channel, and finally the end is capped, poured and cured. Generally, under the influence of concrete impact loads, the inner mold is prone to floating, so a pressure rod device is generally used to limit and fix the inner mold to prevent the inner mold from floating.
