The invention relates to a temporary buckle cable force adjusting device for double-side cantilever type main beam construction and a using method of the temporary buckle cable force adjusting device, and belongs to the technical field of bridge construction. The temporary buckle cable force adjusting device comprises an adjusting sleeve, the two ends of the adjusting sleeve are provided with adjusting rods and connecting nuts respectively, the adjusting rods are arranged in the connecting nuts in a penetrating mode, the exposed ends of the adjusting rods are in threaded connection with the adjusting sleeve, and the two adjusting rods are symmetrically arranged in the adjusting sleeve; a temporary buckle cable comprises a steel strand bundle, one end of the steel strand bundle penetrates through an anchor plate, a P anchor is arranged at the end of the steel strand bundle, a pressing plate is arranged at the end of the P anchor, the pressing plate is fixedly connected with the anchor plate, the anchor plate is arranged in a connecting nut, and the anchor plate and the connecting nut are fixedly connected in a threaded mode. The construction load of the hanging basket in the cantilever state on the two sides of the main beam in the construction process is met, and the cable force of the temporary buckle cable can be adjusted according to the actual construction requirement in the construction process.
Description
technical field [0001] The invention relates to a double-side cantilever type main girder construction temporary buckle cable force adjusting device and a using method thereof, which belong to the technical field of bridge construction. Background technique [0002] Cantilever construction refers to the construction method of setting up working platforms on both sides of the bridge pier, and cantilevering or assembling beam sections to the mid-span segment by segment until the bridge span structure is closed. The characteristic of cantilever construction is that no or less supports can be used, and the construction will not affect navigation or traffic under the bridge. It is also suitable for occasions where the terrain is complex in mountainous areas and high-pier long-span bridges in mountainous areas are not suitable for erecting supports. However, for the main girder with long cantilever pouring construction, the main girder structure generally cannot independently bear...
