Build in the process of bridge, the general constructure scheme of setting up support that adopts when casting bridge pier bent cap, this constructure scheme existence is built long in time limit, fund input is big, build the low shortcoming of used material recycling rate of waterused, simultaneously because the geological condition difference of construction site usually runs into surface settlement, cause the support sedimentation of setting up and be out of shape the casting quality that has badly influenced the bridge pier bent cap, brought potential safety hazard for the bridge of building.
Summary of the invention
The building method of isolated pier bent cap pattern carrier provided by the invention has solved the long in time limit of prior art existence, it is low to build used material recycling rate of waterused, and fund input support sedimentation and deformation big and that set up has badly influenced the technical problem of the casting quality of bridge pier bent cap.
The present invention solves above technical problem by the following technical programs:
The building method of isolated pier bent cap pattern carrier may further comprise the steps:
The first step is welded the first hinge mount pad and the second hinge mount pad respectively at two semi-circular outer middle side parts of anchor ear down, two semi-circular on the outer middle side part of anchor ear weld respectively before main beam supporting seat and back main beam supporting seat, below the two ends, the left and right sides of preceding main beam, weld the 3rd hinge mount pad and the 4th hinge mount pad respectively, below the two ends, the left and right sides of back main beam, weld the 5th hinge mount pad and the 6th hinge mount pad respectively;
Second step was being formed anchor ear under the annular with two semi-circular anchor ears down with the bolt clip in the middle of the bridge pier side, two semi-circular anchor ears of going up are formed anchor ear on the annular with the bolt clip in upper end, bridge pier side;
The middle part of the 3rd step with preceding main beam is fixed together below by bolt and preceding main beam supporting seat, the 3rd hinge mount pad that one end of the LAO brace summer left end by pin and preceding main beam welds below is hinged, the other end of LAO brace summer is hinged with the first hinge mount pad of the arranged outside of the preceding semi-ring of following anchor ear by pin, the 4th hinge mount pad that the right-hand member of one end of right front bearing diagonal beam and preceding main beam welds below is hinged, the other end of right front bearing diagonal beam is hinged with the first hinge mount pad of the arranged outside of the preceding semi-ring of following anchor ear;
The middle part of the 4th step with the back main beam is fixed together below by the back main beam supporting seat of bolt with the outside of the back semi-ring that is fixedly installed on anchor ear, the 5th hinge mount pad that one end of the left back bearing diagonal beam left end by pin and back main beam welds below is hinged, the other end of left back bearing diagonal beam is hinged with the second hinge mount pad of the arranged outside of the back semi-ring of following anchor ear by pin, the 6th hinge mount pad that the right-hand member of one end of right back bearing diagonal beam and back main beam welds below is hinged, the other end of right back bearing diagonal beam is hinged with the second hinge mount pad of the arranged outside of the back semi-ring of following anchor ear;
The 5th step was placed bent cap bed die carriage between preceding main beam and back main beam, at bent cap bed die carriage top casting bridge pier bent cap.
The present invention has shortened the construction period greatly, has saved cost, has improved the casting quality of bridge pier bent cap, convenient disassembly, material repeat usage height.
