Abstract
The invention discloses a kind of construction method of high rigid structure 0# block of pier stud continuous beam, after the completion of including the following steps: formwork installation bracket key box → casting concrete → concreting → installation attached wall, mounting platform and protective net → installation bracket → correction mounting bracket → precompressed → formwork installation Hanging Basket embedded part casting concrete → concreting after the completion of → form removal, bracket and bracket.
Description
Technical field
The present invention relates to technical field of bridge construction more particularly to a kind of construction parties of the rigid structure 0# block of high pier stud continuous beam
Method.
Background technique
Increasingly update with bridge construction technology be constantly progressive, long-span bridge construction of the cross a river across paddy is being built and is being raised
It is increasing to build engineering；The construction height of pier stud is more than hundred meters, and many places are in the environment of complicated topographical conditions, traditional pier stud
0# block construction method such as sets up the requirement that external scaffolding has been unable to meet high pier construction under complicated construction environment.
Summary of the invention
The purpose of the present invention is to solve problems of the prior art, and a kind of high pier stud continuous beam proposed is rigid
The construction method of structure 0# block, adopts the technical scheme that
A kind of construction method of the rigid structure 0# block of high pier stud continuous beam includes the following steps: formwork installation bracket key box → pour
After the completion of building concrete → concreting → installation attached wall, mounting platform and protective net → installation bracket → correction mounting bracket
After the completion of → precompressed → formwork installation Hanging Basket embedded part casting concrete → concreting → form removal, bracket and bracket.
Preferably, when pre-buried bracket key box, guarantee that each pre-buried bracket key box in same level height, is inserted into build-in consolidation,
Reinforced mesh circular bar must be increased at built-in fitting hole and make reinforcement processing；
Preferably, when installing wall-attaching equipment, wall-attaching equipment is required must be horizontal by baseline of bracket key box, and same seat in the plane is each
Wall-attaching equipment needs on the same axis.
Preferably, when attached wall, mounting platform and protective net are installed, attached wall is installed first, after wall-attaching equipment installs, then
Mounting platform and protective net, last mounting bracket.
Preferably, when bracket is installed, corresponding two brackets need to be installed, according to the center of gravity Reasonable Arrangement suspension centre of bracket,
Auxiliary rope is hung on bracket, and pier top descendant is lifted by loop wheel machine and draws auxiliary rope auxiliary in place, after bracket penetrates bracket key box
Bracket is slowly pulled in bracket key box, measures bracket elevation and levelness, plug ensures that bracket is met the requirements under upper pad.
Preferably, corresponding two brackets wear fining twisted steel to drawing after the installation is completed, fining twisted steel band double nut,
It is tight with torque wrench, after bracket installation qualification, lateral is carried out with No. 10 channel steels.
Preferably, the bracket is using 2 PSB830 grades of 32 fining twisted steels of φ as anchoring rod, single finish rolling screw thread
Steel can bear 600KN pulling force.
Preferably, template, bracket remove bracket after the completion of removing, in the pre-buried lifting hole(eyelet) of 0# block bottom plate bracket corresponding position, 0#
After block mount holder is removed, wirerope is penetrated to hoist engine out of lifting hole(eyelet) and lifts wirerope, removed to wearing fining twisted steel, with drawing
Rope pulls out the slow unloading of bracket to cushion cap.
Compared with prior art, the present invention provides a kind of construction method of high rigid structure 0# block of pier stud continuous beam, have with
It is lower the utility model has the advantages that
High pier, which lives the rational design based on 0# block frame system system in climbing formwork for construction, makes three-dimensional construction in high-altitude be changed into two-dimentional put down
Surface construction reduces the security risk coefficient of high-rise working；Calf support platform passes through structural concrete built-in fitting, bracket three's shape
At works-operation platform one stress system, the bearing capacity of structural concrete itself is made full use of；In the construction process without
The allocation and transportation of hoisting machinery are needed, construction equipment is reduced, accelerates construction progress, obtain good economic benefit.
