Form plate system of prefabricated U-shaped beam

Abstract

The invention relates to a form plate system of a prefabricated U-shaped beam and relates to the technical field of prefabricated beam form plates. The form plate system of the prefabricated U-shapedbeam comprises an outer from unit, an inner form unit erected over the outer form unit, and end forms arranged at the two ends of the outer form unit respectively. The outer form unit comprises a bottom form arranged on a pedestal and side forms arranged on the two sides of the bottom form respectively, and a movable bottom plate for opening and closing the bottom from is arranged at the part, where the middle section and the end sections of the U-shaped beam are connected, of the bottom form. One end of the movable bottom plate is hinged to the bottom form, the other end of the movable bottomplate is connected with the bottom from through bolts, movable side plates for opening and closing the side forms are arranged at the parts, located at the movable bottom plate, of the side forms, the upper ends of the movable side plates are hinged to the side forms, and the lower ends of the movable side plates are connected with movable side plates through bolts. The form plate system of the prefabricated U-shaped beam has the advantages of being convenient to operate, needless for removing the side forms and high in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of prefabricated beam formwork, in particular to a formwork system for prefabricated U-shaped beams. Background technique [0002] U-shaped beam is a U-shaped concrete prefabricated beam with open thin walls. Compared with ordinary box girder, U-shaped beam has the advantages of low beam height, good noise reduction effect, high section space utilization, safe driving, beautiful appearance and good visual effect. At present, many intercity light rails and subways in China use prefabricated U-shaped beams as the upper structure. The U-shaped beams include a middle section and end sections respectively set at both ends of the middle section. The bottom of the end section is convex downward. out the bottom of the middle section. [0003] At present, the prefabrication of the U-shaped beam requires the use of formwork. The existing formwork includes an outer mold unit, an inner mold unit suspended above the out...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: Since the side forms need to be installed and disassembled block by block each time they are hoisted, the installation and removal time is long and the work efficiency is low; It is very easy to cause collision and deformation, which brings difficulties to the adjustment of the template in the later stage
