Description
Technical field
The invention belongs to bridge engineering construction technical field, and in particular to a kind of pin-connected panel RPC box beam and
Its construction method.
Background technology
Current railway, highway, municipal bridge box and beam structure use concrete structure, because it is low from the great, strength of materials,
It is constrained to the development in the whole hole Yun Jia directions of large span.The RPC strength of materials is high, good endurance, is applied
In box-beam structure, it is possible to resolve common concrete material from it is great, the strength of materials is low the problem of, but RPC material supplier
The property made difference is, it is necessary to which high-temperature steam curing, high to construction process requirement, and whole hole is cast-in-place or prefabricated construction will to steam-cured house and appointed condition
Ask high, it is difficult to reach humidity and temperature requirement, it is impossible to ensure construction quality.Pin-connected panel RPC of the present invention
Box beam, physical dimension is small, and from heavy and light, span ability is strong；Difficulty of construction can be reduced using construction method of the present invention, it is easy to ensure matter
Amount, available for large-scale industrialized, standardized production, realizes whole hole fortune frame after assembly, investment reduction, the feature of environmental protection is more preferable.
The content of the invention
It is an object of the invention to provide a kind of pin-connected panel RPC box beam and its construction method, by single component
Row is assembled again after prefabricated, solves RPC materials application problem present in box-beam structure.
The technical solution adopted in the present invention is：
Pin-connected panel RPC box beam, it is characterised in that：
Longitudinal direction is made up of the splicing of more piece prefabricated subsection；
The π shapes top plate of prefabricated subsection including top, the π shapes bottom plate of bottom and two blocks of webs of both sides therebetween,
Using RPC material；
The joint of π shapes bottom plate and web is bottom plate and the cast-in-place RPC node of web, and the left and right sides is symmetrical
Set；π shapes top plate is top plate and the cast-in-place RPC node of web with the joint that connects of web, and the left and right sides is symmetrical
Set；π shapes top plate, the π shapes bottom plate of bottom and two blocks of webs of both sides pass through cast-in-place RPC section therebetween
Point is spliced into enclosed construction.
The Mosaic face of prefabricated subsection longitudinal direction both sides is serrated, and splices solid by epoxide-resin glue and contiguous prefabricated section
It is fixed.
The construction method of pin-connected panel RPC box beam, it is characterised in that：
Comprise the following steps：
Step one：Prefabricated π shapes top plate, web and π shape bottom plates：
Prefabricated components group mould, reinforcing bar are placed and reserved steel bar joint；RPC is poured and high-temperature steam curing；
Step 2, single prefabricated subsection spelling：
In spelling platform position by design drawing requirement spelling, connecting node reserved steel bar；Cast-in-place 4 connecting nodes in web top and the bottom
RPC and high-temperature steam curing；Form 1 prefabricated box -beam section；
Step 3：Repeat step two, until the whole precast segments of 1 hole beam are finished；
Step 4：Each prefabricated subsection longitudinal direction is assembled；：
Adjacent segment end face applies epoxide-resin glue；The interim prestressed strand of tensioning；
Step 5：The permanent longitudinal prestressing steel beam of tensioning box beam.
The present invention has advantages below：
The present invention is split a whole hole RPC box beam, is longitudinally divided into multiple sections, longitudinally in each
Section is divided into π shapes top plate, web and π shape bottom plates again, and each plate progress is prefabricated, then cast-in-place to be connected to become single section, often
Individual section forms whole opening box girder by section assembling mode, by prefabricated top plate, bottom plate, by top plate and web connecting node, bottom
Plate is arranged on the less web top and the bottom of stress with web connecting node, has both reduced RPC box girder construction difficult
Degree, also ensure that the stress performance of box beam.
Construction method of the present invention is compared with whole hole RPC box beam, and precast-concrete form is simple, and construction is vibrated
It is convenient, it is not necessary to the steam-cured room and high-power steaming and cultivating equipment of large area, it is easy to quality control, reduced investment, efficiency high, the feature of environmental protection
It is good.Available for a wide range of standardization, batch production, mechanized construction, it is adaptable to whole opening prefabricated, the tool of RPC box beam
Have broad application prospects.
