Abstract
A kind of liftoff bridge-type cast-in-place concrete roadbed hydraulic pressure stress formwork of high ferro is disclosed instead of ground erecting device, and device supports mould bases body using hydraulic pressure stress, and mould bases body is manufactured using channel-section steel and iron plate, if：Way of concrete foundations is 4 meters wide, two bridges pedal span for 18 meters, mould bases body is designed to 4 meters wide, 17.8 rice is long, the two ends of mould bases body length respectively set two hydraulic pressure steel cylinders, the two ends that 4 hydraulic pressure steel cylinders are fixed on mould bases body length turn into an entirety, hold level with both hands under hydraulic pressure steel cylinder in mould bases body lower end, hydraulic column can 2.5 meters of reduction, during cast-in-situ bridge way of concrete foundations, whole weight concrete and mould bases body weight stress are at the basic point of 4 hydraulic column lower ends, pedaled at hydraulic column stress basic point with bridge as an entirety, when cast-in-place concrete bridge is pedaled, hydraulic column stress basic point will simultaneously be poured, the shape of hydraulic column stress basic point is provided in the left and right both sides that bridge is pedaled, highly put down and pedal top in bridge and down measure 5.5 meters.
Description
Technical field
Present invention relates to building field, the support mould bases construction for bridge-type way of concrete foundations that high-speed railway is liftoff.
Background technology
At present in the support mould bases construction of the building liftoff bridge-type cast-in-place concrete roadbed of high-speed railway, the side of mould bases is supported
Method is that whole body frame and mould bases body are combined into using 0.06 meter of iron pipe, and it is enterprising then with the template of fritter to be laid on mould bases again
Row cast-in-place concrete roadbed, construction method less science, waste of manpower is big, and the duration is slow, is configured mould bases and disassembles cumbersome.
The content of the invention
The present invention main purpose is will to build the liftoff bridge-type cast-in-place concrete roadbed iron pipe supporting construction mould of high-speed railway
Support body changes to be, mould bases body is supported with hydraulic pressure stress, and mould bases body constitutes way of concrete foundations width using formed channel steel and iron plate knot
And two bridge pedal the mould bases body of length between span, if：Bridge-type way of concrete foundations that high-speed railway is liftoff is 4 meters wide, and two bridges pedal span
For 1Rice it is long, thus mould bases body is designed to it is 4 meters wide, it is 17.8 meters long, it is high 3 meters, iron plate is then welded on mould bases body plane, shape
It is a mould bases body into mould bases and template, the two ends of mould bases body length respectively set two hydraulic pressure steel cylinders, and 4 hydraulic pressure steel cylinders are fixed on
The two ends of mould bases body length turn into holds level with both hands in mould bases body lower end under an entirety, hydraulic pressure steel cylinder, and hydraulic column can 2.5 meters of reduction, mould
The shape of support body work, figure：It is shown, when cast-in-place concrete roadbed lower end is 5.5 meters with ground level distance, hydraulic column emersion 2.5
Rice, during cast-in-situ bridge way of concrete foundations, whole weight concrete and mould bases body weight stress is in the basic point of 4 hydraulic column lower ends
On, pedaled at hydraulic column stress basic point with bridge as an entirety, when cast-in-place concrete bridge is pedaled it is necessary to which hydraulic column stress basic point is same
When pour, the shape of hydraulic column stress basic point is provided in the left and right both sides that bridge is pedaled, and highly puts down and pedals top in bridge and down measure 5.5
Rice.
Brief description of the drawings
(1) represents hydraulic column in figure, and (2) represent hydraulic pressure steel cylinder, and (3) represent mould bases body.
Embodiment
When liftoff bridge-type cast-in-place concrete roadbed will use the present invention device, (3) mould bases body is pacified with crane first
Between two bridges are pedaled, 4 hydraulic columns of mould bases body lower end are aligned at the concrete stress basic point also poured, (1) hydraulic pressure
(3) mould bases body jacking to trivial fixed height, is now shut hydraulic valve by post emersion, when cast-in-place, the weight and mould of concrete
The weight of support body all stress are at 4 hydraulic column basic points, when needing to disassemble, by (1) hydraulic column retract (2) hydraulic pressure steel cylinder, it is whole
Individual mould bases body lands naturally, and mould bases body then is hung into scene with crane.
Claims (1)
1. a kind of liftoff bridge-type cast-in-place concrete roadbed hydraulic pressure stress formwork of high ferro replaces ground erecting device, device is using independent
Mould bases, it is characterised in that：Cast-in-place concrete roadbed iron pipe supporting construction mould bases structural reform is for being, with hydraulic pressure stress support mould bases
Body, mould bases body constitutes way of concrete foundations width using formed channel steel and iron plate knot and Liang Qiao pedals the mould bases body of length between span,
If：Bridge-type way of concrete foundations that high-speed railway is liftoff is 4 meters wide, and it is 18 meters long that two bridges, which pedal span, and mould bases body thus is designed into 4 meters
Width, it is 17.8 meters long, it is high 3 meters, iron plate is then welded on mould bases body plane, it is a mould bases body, mould bases to form mould bases and template
The two ends of body length respectively set two hydraulic pressure steel cylinders, and the two ends that 4 hydraulic pressure steel cylinders are fixed on mould bases body length turn into an entirety,
Hold level with both hands under hydraulic pressure steel cylinder in mould bases body lower end, hydraulic column can 2.5 meters of reduction, cast-in-place concrete roadbed lower end is with ground level distance
At 5.5 meters, hydraulic column rise from 2.5 meters, during cast-in-situ bridge way of concrete foundations, whole weight concrete and mould bases body weight stress in
On the basic point of 4 hydraulic column lower ends, pedaled at hydraulic column stress basic point with bridge as an entirety.
