Device for linear control of segmental prefabricated assembled curved bridge

Abstract

The invention discloses a device for linear control of a segmental prefabricated assembled curved bridge, which belongs to the technical field of curved bridges. The device for linear control of a segmental prefabricated assembled curved bridge comprises a linear control detection device and a detection method. The linear control detection device comprises a device base; an adjusting base is movably mounted above the device base; a main shaft is fixedly mounted at the top end of the adjusting base, three connecting rings are rotatably connected to the outer wall of the main shaft, first screwrods are in threaded connection with the interiors of the three connecting rings, positioning rods are fixedly connected to the bottom ends of the first screw rods, and connecting sleeves are rotatably connected to the positions, located below the connecting rings, of the outer wall of the main shaft. According to the device, the prefabricated arc-shaped beam body can be detected, whether the arc-shaped curve of the beam body is standard and reaches the standard or not is judged, so that curve bridge linear control is facilitated, and the device is simple in structure, convenient to operate, simple in method process and convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of curved bridges, and more specifically, relates to a device for controlling the alignment of segmental prefabricated curved bridges. Background technique [0002] Curved bridges generally refer to curved girder bridges, and curved girder bridges are girder bridges whose planar alignment is in a certain curved shape. Curved girder bridges refer to girder bridges whose planar alignment is in a certain curved shape. From the point of view of plane shape, most curved girder bridges are located on circular curves, sometimes on transitional curves, and sometimes on circular curves where two circles in the same direction or two opposite circles meet. According to the requirements of ground structures, curved girder bridges are sometimes divided into fan-shaped curved girder bridges or oblique curved girder bridges. Because the force of oblique curved girder bridges is more complicated, designers often try to use...

AI Technical Summary

Problems solved by technology

Assembled curved bridges generally prefabricate several segmented curved beams in the factory. In order to control the linearity of the beams, the linearity of the beams needs to be detected after the prefabrication is completed. However, there is no mature and perfect detection method in the existing technology , it can well detect whether the arc shape of the beam body is standard and up to standard
