Be through frequently with bridge structure form.And the closure section construction of continuous rigid frame bridge then becomes one of critical process.
The template used in the prior art usually occurs that spillage causes quality problems, or even because stress is unreasonable or stent
It is unstable to cause security incident, make claim for eot.For these problems, the utility model proposes it is a kind of it is rational in infrastructure it is continuous just
The template of structure beam bridge closure section.
Utility model content
For the deficiency in the presence of the prior art, the utility model proposes a kind of continuous rigid frame bridge conjunction rational in infrastructure
The template of imperial section, it is simple in structure, security risk is reduced, prevents quality problems, shortens the construction period.
The utility model is realized by following scheme：
A kind of template of continuous rigid frame bridge closure section, including stent, the cradle top are laid with some compact arranged
The lumps of wood forms jacking, and the fixed tight bamboo slab rubber of piece that is laid with forms bed die on jacking, and the bamboo slab rubber is 1.2m × 2.0m, thick
Spend for 1.2cm；The side form of rectangular frame is set on the bed die, and the side form pricks screw thread pair by the punching block being oppositely arranged using essence
Pull system is fixed, fixed setting wooden model inside punching block, the fixed bamboo slab rubber of mould inner surface, and malthoid is laid with the bamboo slab rubber；It is described
Fixed and supported by steel pipe scaffold outside punching block.
Preferably, the jacking is alternately arranged close-packed arrays using the lumps of wood of 10cm × 10cm, bottom uses some
The long lumps of wood away from 30cm is fixed on stent, and this structure makes the lumps of wood be not in whole seam rupture when undertaking power.
Preferably, the stent is full hall foot hand stent, upright bar main body spacing is 0.6m × 0.9m, 0.6m at jacking ×
0.6m, horizon bar step pitch are 0.9m, and scaffold centre and periphery are arranged circumferentially bridging, and are continuously set by ground to template face
Put, bridging is 45 °~60 ° with ground elevation, and vertical bridging is set every four rows, and spacing is not more than 6m, horizontal cross brace
By every two rows of settings together, bottom of upright rod sets bar of sweeping the floor.
Preferably, the bamboo slab rubber long side along bridge to arrangement.
Preferably, the stent is built with C15 concrete hardenings and levelling scar, concrete hardening layer thickness
Not less than 10cm.
Preferably, the nut bearing of long bolt sets wooden unit inside the side form.
The beneficial effects of the utility model are：
1st, supported using full hall foot hand stent, foot hand stent is built on concrete layer, and support is more firm；Jacking uses
The lumps of wood is alternately arranged, and is not in the fracture of whole seam, reduces security risk；
2nd, bamboo slab rubber long side makes side form more regular consistent with the seam of bed die, and be laid with bamboo slab rubber along bridge to arrangement
Malthoid, mortar leakage prevention；
3rd, the nut bearing of long bolt sets wooden unit inside side form, and paddle can be mended after form removal, is prevented because of nut corrosion
Caused problem of appearance.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of the utility model embodiment bed die and side form.
Fig. 2 is the side structure schematic view of the utility model embodiment.
Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines specific attached drawing, and the utility model is expanded on further.
By taking the true highway TJ4 work areas flower Milky Way bridge in Nanchuan to road as an example, this spanning footpath is combined as 85+148+85 meters even
Continue firm structure, bridge total length is 326.0 meters, and double width bridge, box beam uses single box single chamber, and 12 meters of case top width, bottom is 6 meters wide, unilateral
3 meters of edge of a wing length.Main bridge single width box beam totally 2 cast-in-place segments, 2 end bay closure segments and a mid-span closure segment.
On the scar that flower Milky Way bridge side span Cast-in-Situ Segment scaffold basis is slotted in Blasting Excavation abutment, then use
The concrete of C15 is hardened, is levelling, and concrete hardening thickness is not less than 10cm, and foundation capability is fully able to meet foot
Hand cradle sets up requirement.
This bridge end bay Cast-in-Situ Segment full framing determines to select 48 × 2.75 steel pipes of specification Φ, Q235A, 1 main body spacing of upright bar
For other 0.6m × 0.9m of 0.6m × 0.6m at jacking, 2 step pitch of horizon bar is 0.9m, and the circumferential and middle setting in scaffold periphery is cut
Knife support 5, and continuously set by ground to top surface is operated, between bridging 5 and ground elevation are 45 °~60 °, middle bridging 5
Set every four rows, spacing is not more than 6m, and horizontal cross brace is pressed to be set together every two steps, and bottom of upright rod sets bar of sweeping the floor；Jacking 3
Close-packed arrays are alternately arranged using the lumps of wood of 10cm × 10cm, stent is fixed in bottom using the long lumps of wood 4 of some spacing 30cm
On, a root long lumps of wood is fixed on each horizon bar, stabilization beam of the root long lumps of wood as jacking is also set up between horizon bar.
After after holder jacking 3, installation is complete, measuring respectively goes out the sideline of Cast-in-Situ Segment box girder web side concrete, then by template construction
Personnel eject bed die sideline, and then installation dimension be bamboo slab rubber 6 that 1.2m × 2.0m thickness is 1.2cm on the lumps of wood again, elder generation two
Side is middle again, need to carry out the adjustment of plane side when last middle block bamboo slab rubber is put when on curve with portable plane, install, piece is tight
After reality, it is fixed on the lumps of wood.
Side form panel is pricked screw thread using essence and machined roadbed 1 is fixed on to pull system 10 using the big punching block 7 of customization
On, it is firm to be supported using steel pipe scaffold, the inside of punching block 7 fixed setting wooden model 8, the fixed bamboo slab rubber 6 of mould inner surface, inside side form
The nut bearing of long bolt sets wooden unit 9.
Bamboo slab rubber long side is along bridge to arrangement so that side form is consistent with end template piece rule, and bamboo film face is laid with one layer
11 mortar leakage prevention of malthoid.
In order to ensure the safety of stent, the plastic set of stent is eliminated, while measures the elastic settlement amount of stent, is stent
Arch rise left in advance foundation is provided, pre-pressing bracket uses molding concrete block and bundled steel strand wires or reinforcing bar piling prepressing.
Above description is merely a prefered embodiment of the utility model, on the scope of protection of the utility model is not limited in
Embodiment is stated, every technical solution for belonging to the utility model principle belongs to the scope of protection of the utility model.For this
For the technical staff in field, some improvement for being carried out on the premise of the principle of the utility model is not departed from, these improvement
It should be regarded as the scope of protection of the utility model.
