The rainproof construction method construction sequence of precast bridge concreting:
One), step one: hide template with awning
Intake in template during for preventing rainy, bridge formwork installs awning.
1, awning structure
Awning shaped steel does skeleton, and color steel is Peng Ding, lean-to drainage, outside template.Rainproof canopy is along the elongated layout of template total length.For ease of lifting, be divided into several sections of.Certain overlap joint is had between joint and joint.Template one fixed width chosen by awning top board.Rain shade column lower end makes plug by falsework size suitable for reading.
2, awning is installed
Before beam body concrete is built, by overlap joint order from beam forms one end lifting awning sections, in suitable for reading for awning column lower end plug insert molding timbering, be connected firmly.See accompanying drawing 1.
Two), step 2: with band rainhat hopper transport concrete
During for preventing concrete hopper transport concrete, water inlet in hopper, adopts the hopper transport concrete of band rainhat.
Rainhat is a taper canopy structure.Make skeleton with angle steel, cover color steel top above.See accompanying drawing 2.Rainhat tipping concrete removed by hopper after entering agitator, fill rainhat on concrete bonnet.Then with transport vehicle hopper is transported to and waits to build by concrete beam.
Three), step 3: build chassis concreting with rainproof movement
Concrete owing to having installed awning above bridge formwork, template top hidden, so can not be built from the lifting of template top.Build for solution concrete enters mould, have employed the rainproof movement of developing voluntarily and build chassis from beam sides concreting.
1, trolley structure is built in rainproof movement
Rainproof movement builds chassis by running truck, rack platform, receiving hopper, fixedly slip
Groove, rotating chute five part form.See accompanying drawing 3.
Running truck is electric track flatcar, drives, the track of the steel rail laying inside bridge formwork is walked with battery.Can contraposition discharging between each sections of bridge length direction.Chassis has rail clamping device.
Support shaped steel is made, and is arranged on running truck.Support is provided with operating platform, for operative provides the scope of operation.Frame overhead welding has steel plate awning lid.Support is provided with unload concrete receiving hopper and fixed chute that welded steel plate becomes.The discharging opening of receiving hopper is to suitable for reading at fixed chute, and concrete to be slipped by fixed chute from receiving hopper outlet and delivers to rotating chute.
Receiving hopper is provided with receiving hopper rainhat.Receiving hopper rainhat is rotatable by the rotating shaft being installed on frame top rain-proof fluffied and covering, and can be fixed by latch,
Rotating chute welded steel plate forms.Be arranged in the rotating shaft of being fixed on chassis, rotating 180 deg.
2, chassis use is built in rainproof movement
Before chassis moves, pack up rail clamping device, and rotating chute is rotated to groove body and beam forms parastate, collide to avoid chute and template awning column.Then start chassis, chassis is moved to the position that bridge formwork needs concreting.
After chassis is in place, puts down rail clamping device and be clamped on rail, and rotating chute is rotated to groove body and beam forms upright position.Now, can start to lift above concrete hopper to chassis receiving hopper, remove rainhat on receiving hopper, open concrete hopper bottom valve and unload concrete in receiving hopper.Concrete is slipped by fixed chute and swivel chute to be delivered in bridge formwork, carries out concreting.
Movement is built chassis using state schematic diagram and is seen accompanying drawing 4.
