Embodiment Construction

[0036] The present invention aims at the defects of the conventional support frame at the side web 12 and the wing plate 13 of the cast-in-place box girder. and the wing plate support frame for R&D and design, and finally invented a simple assembly and disassembly, convenient adjustment, easy control and inspection, especially for the box girder of the cast-in-situ box girder bridge width gradient section (curve section, lane change section, main line connection) ramp section, etc.), where the line shape of the side web 12 and the wing plate changes a lot, it is more conducive to its line shape control, and conforms to the relevant codes, standards and design requirements. In order to achieve the purpose of guaranteeing construction quality, improving construction efficiency and saving resources. The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The cast-in-place box girder side web 12 and the integral support fram...

Abstract

The invention relates to a cast-in-place box girder side web plate and wing plate integration supporting frame. An under-frame is horizontally arranged, one end of a web plate supporting rod is connected with one end of the under-frame in a movable mode, the other end of the web plate supporting rod is connected with one end of a wing plate supporting rod in a movable mode, one end of a wing plate adjusting rod is connected with the other end of the under-frame in a movable mode, and the other end of the wing plate adjusting rod is connected with the other end of the wing plate supporting rod in a movable mode; one end of a web plate adjusting rod is connected with the waist part of the web plate supporting rod in a movable mode, and the other end of the web plate adjusting rod is connected with the under-frame in a movable mode; the lengths of the web plate supporting rod, the wing plate adjusting rod and the web plate adjusting rod are adjustable. According to the cast-in-place box girder side web plate and wing plate integration supporting frame, a side web plate and wing plate bracket of a cast-in-place box girder is separated from the whole to be designed as a tool-type bracket, compared with traditional brackets, the bracket is simpler and quicker and convenient to control, the technical problem is solved that the box girder side web plate and wing plate bracket is tedious to construct and dismount in a construction process, and materials are saved..

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to a supporting structure of side webs and wing plates in cast-in-place box girder bridge construction. Background technique [0002] With the rapid development of my country's transportation industry and urban construction, especially in the context of the continuous development of the transportation industry and the continuous growth of traffic flow, a large number of overpasses and level crossing bridges have been built. For viaducts and overpasses, it is usually necessary to set up branch links with variable slope, variable curvature, and variable width at the connection between the main bridge and the ramp, and between the main line and the branch line, resulting in many bridges with irregular geometric shapes. [0003] At present, the construction of the special-shaped section is mainly realized through the adjustment of the support of the lower web and wing plate of...
