Description
Technical field
The present invention relates to technical field of bridge construction more particularly to a kind of bridge hanging basket template and its installation methods.
Background technique
Bridge engineering mainly studies bridge water way survey, determines bridge aerodynamics, considers navigation and line requirements to determine bridge floor
Highly, considering that substrate is not washed away or frost heave is to determine embedded depth of foundation, design diversion structure etc., bridge style designs,
Bridge structure design, bridge construction, rating bridge, bridge testing, bridge maintenance aspect, Hanging Basket is the master in bridge cantilever construction
Equipment is wanted, truss-like, cable-stayed type, fashioned iron formula and four kinds hybrid can be divided by structure type, according to concrete cantilever construction work
Various forms Hanging Basket feature, weight is comprehensively compared, using steel type, construction in the requirement of skill requirement and design drawing to Hanging Basket
Technique etc.；Hanging Basket design principle: from heavy and light, structure is simple, more stable and stronger, move forward and be convenient to mount and dismount, have it is stronger repeatable
Usability deforms the features such as small after stress, and Hanging Basket down space is sufficient, it is possible to provide larger operation side is conducive to reinforcing bar mould
Plate constructing operation.
It needs to be laid with Hanging Basket template in beam body in Hanging Basket installation process, the template of Hanging Basket is divided into bed die, external mold, the edge of a wing
Backform in plate and chamber, the bed die of Hanging Basket, external mold, flange plate, backform is all made of plank sheathing in chamber, is pacified using existing template
Dress method is laid with template, it may occur that the related concrete falling accident of Hanging Basket, therefore, it is proposed that a kind of bridge hanging basket template
And its installation method.
Summary of the invention
The purpose of the present invention is to provide a kind of bridge hanging basket template and its installation methods, to solve existing template peace
Dress method is laid with template, it may occur that the problem of Hanging Basket related concrete falling accident.
To achieve the above object, the invention provides the following technical scheme:
A kind of bridge hanging basket Formwork Installation Method, steps are as follows:
S1, Hanging Basket is chosen respectively according to construction plan needed for template, wherein Hanging Basket bed die, external mold, flange plate, chamber
Interior backform is all made of plank sheathing, and levelling, correction are carried out after template installation, and template top relative relief is less than 2mm, and diagonal error is small
After 5mm, whole bolts, pull rod and support are tightened；
The installation of S2, Hanging Basket bed die, external mold are completed with cradle construction step sequence, and Hanging Basket bed die, external mold are separately mounted to Hanging Basket
On bed die mounting platform and external mold mounting platform, backform is because of presstressed reinforcing steel pore-forming pipeline location difference, ruler in flange plate and chamber
The easily damaged reason of very little different and demoulding, backform carries out restructuring or again prefabricated in flange plate and chamber, and will re-work
Bulkhead is placed in corresponding beam section beam-ends；
S3, box girder segment filling concrete finish, and the side form of non-bearing is removed when reaching 70% design strength by maintenance
Plate；
S4, plug mould is removed, then the bolt on block-by-block disassembly plug mould strikes plug mould in disassembly process
It beats, the plate face and yoke of internal model and hole mould are extracted out after breaking from hole, then clean arrangement with water, are stored indoors, in case next time
It uses；
S5, disassembly external mold, after pumping split bolt, first pull interior side form with jack, remove inside lower end part template, so
Loosen interior skid beam sunpender with jack afterwards, promote its interior backform truss and backform is driven to be detached from beam section top plate, suspended basket in place after, adjust
Whole beam section bed die absolute altitude, and keep outer side mold in place.
As a further solution of the present invention: template with a thickness of 1-2cm.
As the present invention further scheme: template with a thickness of 1.5cm.
As further scheme of the invention: in step S2, the installation method of Hanging Basket bed die mounting platform are as follows: bed die is flat
Then platform installs bottom die platform rear cross beam, and be anchored in and applied with sunpender using integral hoisting after assembled or installation on ground in situ
Work beam section, front beam are installed and are anchored in preceding upper beam with sunpender, lateral connection is then installed and carried out to stringer, front and back is hung
Stage+module, operating platform installation before then carrying out finally complete end template installation.
In conclusion the beneficial effects of the present invention are: this invention ensures that the quality of hanging basket for bridge construction, while template
Dismantle it is easy for installation, it is pollution-free to concrete surface, long-acting can be used for multiple times, save construction cost.
