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 mold system, belonging to the technical field of bridge prefabricated box girder pouring, and in particular to a novel box girder bottom mold system with adjustable bottom mold positions. Background technique [0002] For the prefabrication of short-line matching segment beams, the template design and application of prefabricated short-line segment beams on straight lines and contour sections are relatively mature at home and abroad. However, for the large-span and gentle curve prefabricated templates that have appeared in recent years, For example, the cross slope of the bridge deck is within the 65m bridge length range, the cross slope will gradually change from +2% to -2%. K6+666.779~K6+731.779 is the super-elevation transition section, 65m long, the left bridge cross slope is -2%, and the right bridge cross slope is +2%. At this time, if the existing technology of box girder prefabricated steel is used The f...
