Description

Double-side rib plate type main beam template device of concrete cable-stayed bridge Technical Field The utility model belongs to the technical field of bridge pouring auxiliary systems, and particularly relates to a main beam template device of a bilateral rib plate type of a concrete cable-stayed bridge. Background The cable-stayed bridge is also called as a combined system bridge, is a bridge in which a main girder is directly anchored on a cable tower by a plurality of stay cables, is a structural system formed by combining a pressure-bearing tower, a tension cable and a bending-bearing beam, and can be regarded as a multi-span elastic support continuous beam with stay cables instead of buttresses. The arrangement form can reduce the bending moment in the beam body, reduce the building height, lighten the structure quality and save the materials. The cable-stayed bridge is used as a inhaul cable system, has larger spanning capacity than a beam-type bridge, and is a main bridge type of a large-span bridge. The main beams of the cable-stayed bridge can be divided into four main categories according to material structures, namely, a concrete main beam, a steel-concrete combined beam and a steel-concrete mixed beam. Although the span capacity of the concrete cable-stayed bridge is not as great as that of the steel girder, the construction speed is not as fast as that of the steel girder, but the concrete cable-stayed bridge has the advantages of low manufacturing cost, simple later maintenance, large rigidity, small deflection, good wind resistance stability and the like, and is a preferred bridge type with the span of the main span in the range of 200 m-500 m. For the double-cable-plane cable-stayed bridge, the cross section of the main girder of the double-side rib plate has simple structure and can adopt the front supporting point hanging basket for cantilever pouring construction, thereby being convenient for construction. When the concrete cable-stayed bridge girder adopts a front supporting point hanging basket cantilever pouring construction process, after the construction of one girder segment is completed, the hanging basket needs to move forward to the position of the next girder segment to continue the construction. Before the hanging basket moves forward, the hanging basket template is required to be dismantled and lowered below the bottom of the girder diaphragm, so that the hanging basket can smoothly move forward to the next girder section, and the lowering height of the hanging basket is required to be determined according to a template system. Because the hanging basket template area is large, the support frames are more, the template construction operation space is limited, and the template is removed and installed for a long time, the removal and installation of the template directly affect the construction period of one girder segment. Disclosure of utility model The utility model aims to provide a bilateral rib plate type main beam template device of a concrete cable-stayed bridge, which solves the problem that the template is time-consuming and labor-consuming to disassemble and assemble due to the limited template construction operation space in the prior art.
