Abstract

The invention relates to a construction method of a fixed-end beam and a fixed-end beam structure, comprising: dropping the main beam so that the fixed end of the main beam is supported on a temporary support; constructing a fixed foundation on the end face of the fixed end; removing the temporary support to form Solid end beam. By implementing the invention, the negative bending moment at the fixed end of the fixed-end beam can be reduced, so that it is unnecessary to install a large-volume fixed foundation, which effectively reduces the design size and scale of the fixed-end foundation, saves construction costs, and also makes the fixed-end beam The overall structure is more coordinated; the method of the present invention can also flexibly adjust the overall bending moment distribution of the fixed-end beam according to needs, and increase the span of the main beam through pre-designing to adjust and increase the beam body bending moment of the main beam and further reduce the fixed-end beam. In order to reasonably distribute the beam body bending moment and fixed end negative bending moment of the main girder, the supporting capacity and mechanical performance of the beam body itself can be fully exerted, and at the same time, the scale of the fixed foundation at the fixed end can be flexibly controlled. construction freedom.

Description

Technical field [0001] The present invention relates to the field of bridge construction, and more particularly to a method of construction of the fixed beam and fixed beam structure. Background technique [0002] In the bridge construction, the fixed beam with one end fixed means one or both ends fixed simply supported beam. The vertical loads, a fixed end fixed beam in addition to receiving vertical forces, but also withstand the negative moment. like figure 1 Shown is a conventional fixed beam 10, which employs a drop frame construction, i.e., after the landing gear fixed end 11 is directly provided on the surface of the lower structure 20 on the ground fixed beam 10, in the Bridge state the weight causes the fixed end of the beam 10 fixed end 11 under a lot of negative moment, fixed end-based design size and generally large scale, high construction costs and unsightly overall structure. [0003] For the construction of a conventional fixed beam landing gear, on the one hand f...
