Problems solved by technology

However, these two methods have relatively large limitations. The first two methods are only suitable for single-cable plane cable-stayed bridges or π-shaped girder cable-stayed bridges.
However, for double-cable plane box girder cable-stayed bridges, the above two forms are not applicable
Double-cable plane box girder cable-stayed bridges have a large height away from the hanging basket due to the lifting of the box girder flange. The shear block is too high if the hanging basket is used, which will generate a large bending moment on the hanging basket, making the design of the hanging basket more difficult and increasing the hanging basket. Basket production cost; using concrete box girder to set shear block to form thrust will cause large temporary structure of concrete box girder structure, increase construction difficulty and affect the appearance quality of box girder

Abstract

The invention discloses a cable-stayed basket thrust device, which comprises an anchor chock and a pull rod which are adaptive to a cable-stayed bridge box girder anchor block. The anchor chock is anchored on a stayed cable and is in close fit with the anchor block. Anchor plates are arranged on the two sides of the anchor chock. One end of the pull rod is connected with the main longitudinal girder of a basket and the other end. The invention has the advantages that the exterior quality of the box girder can be ensured and the basket is prevented from moving backward.

Description

technical field [0001] The invention relates to components of a cable-stayed hanging basket, in particular to a thrust device for a cable-stayed hanging basket. Background technique [0002] The cable-stayed bridge concrete pouring construction adopts the cable-stayed hanging basket. Since the rear end of the cable-stayed hanging basket is anchored on the poured beam section, and the front end and the cable-stayed cable are fixed by a tensioning device, the hanging basket generates a horizontal force component. , therefore, a device that can resist the horizontal force component is needed to prevent the hanging basket from retreating. In conventional concrete construction, the horizontal thrust device of the cable-stayed bridge adopts holes left at the bottom of the concrete, and shear blocks are set on the hanging baskets to resist the horizontal component force of the cables; In direct contact with the shear block to resist the horizontal force component of the stay cable...
