Description
Technical Field
The utility model relates to a cable-stay bridge mounting system, in particular to H type single tower two-cable-side prestressed concrete cable-stay bridge mounting system.
Background
A cable-stayed bridge is also called a diagonal tension bridge, is a bridge with a main beam directly pulled on a bridge tower by a plurality of guys, and is a structural system formed by combining a pressure-bearing tower, a pulled guy and a bending-bearing beam body. It can be seen as a multi-span elastically supported continuous beam with guy cables instead of buttresses. It can reduce the bending moment in the beam body, reduce the building height, lighten the structural weight and save materials. The cable-stayed bridge mainly comprises a cable tower, a main beam and a stay cable.
The construction of the main beam of the cable-stayed bridge is generally to arrange a temporary buttress, can be directly assembled or poured on a bracket, and also can arrange a temporary beam on the temporary buttress and assemble or pour on the temporary beam. Therefore, the erection of the bracket system is the best method for constructing the main beam.
The existing support system can not meet the requirements of stability and bearing capacity of the whole support for some high girders.
Disclosure of Invention
In order to solve the problem of the prior art, the utility model provides a two cable face prestressed concrete cable-stay bridge braced system of H type single tower, it adopts the support to take to try, not only can reduce die carrier system cost, can guarantee moreover that braced system is stable, ensures construction safety, satisfies flood prevention requirement, can directly reduce the cost again, guarantees the construction progress.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides a two cable face prestressed concrete cable-stay bridge braced system of H type single tower, includes the bottom support, bottom support below concretize on deepening the bored concrete pile of underground through the concrete foundation, bottom support top is provided with crisscross I-steel group, crisscross I-steel group top be connected with respectively and be used for supporting the limit girder support of limit girder, be used for supporting the diaphragm support of diaphragm and be used for supporting the girder roof support of girder roof.
The side girder support, the diaphragm support and the girder roof support are connected with each other to form a whole.
The staggered I-steel groups comprise middle longitudinal I-steel groups, and the upper part and the lower part of each middle longitudinal I-steel group are respectively fixedly connected with transverse I-steel groups.
