Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a measuring device for installing a steel box girder. Background Art

[0002] Steel box girder, also known as steel plate box girder, is a common structural form for large-span bridges. It is generally used on bridges with larger spans. It looks like a box, so it is called a steel box girder. Steel box girders are often manufactured in the factory, transported to the installation site, and then lifted by a crane for installation. During installation, they often need to be installed in alignment with other installed steel box girders. The distance between the steel box girders cannot be measured during installation. If they are not installed in a straight line and the distance between the ends is large, the overall bridge will be distorted, affecting its safety and service life.

[0003] During the installation of the steel box girder, a measuring device needs to be used for monitoring to ensure that the steel box girder is installed in place; the existing measuring device, such as the bridge beam plate installation displacement measuring device disclosed in patent CN219589574U, includes a bridge pier, and a left beam plate and a right beam plate are respectively arranged on the left and right sides of the upper end of the bridge pier. The upper surface of the bridge pier is fixed with a mounting plate by bolts, and a fixing block is welded on the mounting plate. A second scale plate is fixed to the rear side of the right surface of the left beam plate, and a first scale plate is fixed to the front side of the left surface of the right beam plate. The front surface of the second scale plate and the rear surface of the first scale plate are both provided with movable grooves. The measuring device has the following defects: the measuring device is installed on the bridge pier as a whole, which is relatively fixed. After the bridge plate is installed, it cannot be taken out, and it cannot be flexibly moved and adjusted, and the effective measurement of the inclination angle of the bridge plate cannot be achieved.
