Description
Technical Field
The utility model relates to a bridge engineering technical field, concretely relates to beam arch joint construction.
Background
The box girder structure has certain advantages in bridge construction due to simple vision and large bending rigidity and torsional rigidity, so that the box girder bridge is widely applied to the construction of highway bridges, municipal bridges and railway bridges, and the cast-in-place continuous box girder can be well adapted to line types, can realize widened bridges, obliquely bent bridges, ramp bridges with small curve radiuses and the like, and is widely applied to bridge engineering, particularly urban bridges.
The arch bridge is an old bridge type and also a bridge type frequently used in modern bridge construction, the arch bridge mainly bears vertical load in use, under the working condition, vertical counter force and horizontal thrust can be generated at the supporting positions of two ends of the arch bridge, and the generation of the horizontal thrust enables axial pressure to be generated in the arch bridge and mid-span bending moment to be reduced, so that the strength of a main arch section material of the arch bridge is fully exerted, and the spanning capability is increased, therefore, the arch bridge is more applied in bridge engineering construction, particularly in landscape bridges.
In the existing box girder structure technology, the cast-in-place box girder structure still has the defects, limitations or shortcomings in different aspects. The cast-in-place reinforced concrete box girder and the prestressed reinforced concrete box girder have larger dead weight, and 60 to 80 percent of the bearing capacity of the cast-in-place reinforced concrete box girder is used for bearing self dead load, so that certain requirements are required in the design of the section of the box girder to meet the requirement of the bending resistance bearing capacity of the bridge, for example, the height of the section of the constant-section continuous box girder is 1/15 to 1/18 of the span. However, in bridge engineering design, especially in urban bridge design, the building height of the upper structure of the bridge is often limited, so that the common cast-in-place concrete box girder can not meet the design requirement of the building height of the upper structure of the bridge, and in order to solve the technical problem, the steel box girder structure is generally adopted to replace the concrete box girder in the prior art, although the structural strength of the steel box girder structure is high, the problem of insufficient structural rigidity caused by too small cross-section height is easily caused because the cross-section girder height of the constant cross-section continuous box girder is generally 1/15-1/18 of the span.
