Abstract
The invention relates to a bridge support exchanging and lifting reaction frame. The bridge support exchanging and lifting reaction frame comprises a horizontal bearing beam which is placed between original bridge supports, a plurality of groups of bearing frameworks are arranged on two sides of a capping beam, longitudinal bearing beams are mounted at the tops of the bearing frameworks, and a plurality of groups of jacks are placed at the upper parts of the longitudinal bearing beams to be used for lifting a bridge body. According to the bridge support exchanging and lifting reaction frame provided by the invention, a structure that the horizontal bearing beam, the longitudinal bearing beams and the bearing frameworks are matched is adopted, so that the weight of the bridge body is allocated to the capping beam through the bearing frameworks and the horizontal bearing beam. According to the bridge support exchanging and lifting reaction frame disclosed by the invention, a separate reaction pier or a processing steel hoop does not need to be established, so that the construction technology is simple and convenient and free from the limit of the shapes of pier columns and the bearing capacity of foundations, and the bridge support exchanging and lifting reaction frame is economical and practical.
Description
Technical field
The present invention relates to a kind of Bridge Support Replacement support, be specifically related to a kind of reaction frame utilizing self bent cap weight capacity, belong to bridge strengthening construction field.
Background technology
Old bridge bent cap bearing replacement often adopts the mode arranging interim counter-force pier or arrange stirrup reaction frame on pier stud to complete, when running into bearing capacity of foundation soil difference, often need to carry out foundation improvement during pier stud out-of-shape improve bearing capacity or process special shape stirrup to change construction, construction cost is high, and waste is large.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of this invention is to provide a kind of Bridge Support Replacement jacking reaction frame, applying this support is not needing under the condition resetting interim counter-force pier and processing stirrup, solve the technical problem of Bridge Support Replacement, the method cost is low, construction speed is fast, and reusable.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Bridge Support Replacement jacking reaction frame, comprise horizontal spandrel girder, horizontal spandrel girder is placed between the original bearing of bridge, be provided with in bent cap both sides and organize supporting frame more, longitudinal spandrel girder is arranged on supporting frame top, and longitudinal spandrel girder top is placed many group jack and is used for jacking bridge beam body.
Described horizontal spandrel girder two ends are provided with the beam tie bar plate with many group bolts hole, and stiffener one end is connected with beam tie bar plate, and the other end is connected with supporting frame, are improved the supporting capacity of supporting frame by oblique layout stiffener.
Described horizontal spandrel girder and supporting frame adopt shaped steel to make, and are connected to form main counter-force load-carrying members between shaped steel by many group high-strength bolts.
Described supporting frame inside is provided with inside connecting rod, for improving the stability of supporting frame.
Bridge Support Replacement jacking reaction frame provided by the invention, by the structure adopting horizontal spandrel girder, longitudinal spandrel girder matches with supporting frame, distributes to bent cap by bridge beam body weight by supporting frame and horizontal spandrel girder.The present invention is without the need to setting up independent counter-force pier or processing stirrup, and construction technology is easy, does not limit by pier stud shape and bearing capacity of foundation soil, economical and practical.
