Abstract

The invention discloses a novel box girder bottom die system. The novel box girder bottom die system comprises a bottom die trolley installed on a preset rail. A bottom die is connected to the bottom die trolley. A hydraulic jacking oil cylinder used for jacking the bottom die, a hydraulic horizontal moving oil cylinder used for horizontally moving the bottom die, and a rotation hydraulic oil cylinder used for rotating the bottom die are arranged on the bottom die trolley. A bottom layer support is arranged between the bottom die trolley and the bottom die. Bottom die hydraulic ejector rods used for adjusting the inclination angle of the bottom die and a fixing rotary rod used for fixing the position of the bottom die are arranged between the bottom layer support and the bottom die. The novel box girder bottom die system is simple in structure and convenient to machine and use, the position and inclination angle of the bottom die can be effectively adjusted according to the requirements of different sections of ultrahigh distorted bridges of large-span small-radius bridges, and fast automatic construction of the ultrahigh distorted large-span small-radius bridges is achieved.

Description

technical field [0001] The invention relates to a box girder bottom formwork system, which belongs to the technical field of bridge prefabricated box girder pouring, in particular to a box girder bottom formwork system whose position of the bottom form can be adjusted. Background technique [0002] For short-line matching segmental beam prefabrication, the formwork design and application of short-line prefabricated segmental beams on straight lines and equal heights are relatively mature at home and abroad. If the cross slope of the bridge deck is within the bridge length of 65m, the cross slope gradually changes from +2% to -2%. K6+666.779~K6+731.779 is the superelevation gradient section, 65m long, the cross slope of the left bridge is -2%, and the cross slope of the right bridge is +2%. The formwork system needs to prefabricate multiple groups of different types of bottom formwork systems according to different sections of the bridge to adapt to the pouring of the bridge...
