Rotating chute forms with welded steel plate, is obliquely installed and rotates to be installed on the rack platform.The cell body upper end is welded on the rotating shaft.Cell body is divided into a pole, and the upper and lower side of pole is welded in respectively in cell body and the rotating shaft.The upper and lower end of rotating shaft is installed in the upper and lower bearing support.Top chock is installed on the rack platform bottom, and step is installed on running truck top.Therefore, cell body and rotating shaft can be done 180 ° of rotations together.30 ° of chute groove body horizontal slopes.The height of rotating chute end opening is higher than the upper open height of bridge formwork, and the position can reach in the middle of the bridge web.
The rainproof job practices construction sequence of precast bridge concreting:
One), step 1: hide template with awning
Intake in the template when preventing from raining, at bridge formwork awning is installed.
1, awning structure
Awning is done skeleton with shaped steel, and color steel is Peng Ding, and lean-to drainage is discharged to the template outside.Rainproof canopy is along the elongated layout of template total length.For ease of lifting, be divided into several sections of.Between joint and the joint certain overlap joint is arranged.The awning top board is chosen the template certain width.The rain shade column lower end is made plug by falsework size suitable for reading.
2, awning is installed
Before the beam body concrete is built, press the overlap joint order from beam forms one end lifting awning sections, with awning column lower end plug insert falsework suitable for reading in, be connected firmly.See accompanying drawing 1.
Two), step 2: with band rainhat hopper transportation concrete
When preventing concrete hopper transportation concrete, the hopper transportation concrete with rainhat is adopted in water inlet in the hopper.
Rainhat is a taper canopy structure.Make skeleton with angle steel, the above covers the color steel top.Hopper is removed rainhat tipping concrete after advancing agitator, fills rainhat on the concrete bonnet.Then with transport vehicle hopper is transported to and waits to build by the concrete beam.
Three), step 3: build the chassis concreting with rainproof movement
Because awning has been installed above the bridge formwork hides template top, so concrete can not be built from the lifting of template top.Build for the solution concrete enters mould, adopted the voluntarily rainproof movement of development to build chassis from the beam sides concreting.
1, trolley structure is built in rainproof movement
Rainproof movement is built chassis and is comprised of running truck, rack platform, receiving hopper, fixed chute, rotating chute five parts.
Running truck is electric track flatcar, drives with battery, walks at the track of the steel rail laying of bridge formwork inboard.Can contraposition discharging between each sections of bridge length direction.Chassis has rail clamping device.
Support is made with shaped steel, is installed on the running truck.Support is provided with operating platform, for workman's operation provides the scope of operation.The frame overhead welding has steel plate awning lid.Unload concrete receiving hopper and fixed chute that welded steel plate becomes are installed on the support.The discharging opening of receiving hopper is to suitable for reading at fixed chute, and concrete slips by fixed chute from the receiving hopper outlet and delivers to rotating chute.
Receiving hopper is provided with the receiving hopper rainhat.The receiving hopper rainhat is rotatable by the rotating shaft that is installed on frame top rain-proof fluffied and covers, and can fix by latch, and rotating chute forms with welded steel plate.Be installed in the rotating shaft of being fixed on the chassis capable of rotating 180 deg.
2, the 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 the rail, and rotating chute is rotated to groove body and beam forms upright position.At this moment, can begin to lift concrete hopper to chassis receiving hopper top, remove rainhat on the receiving hopper, open concrete hopper bottom valve and in receiving hopper, unload concrete.Concrete slips by fixed chute and swivel chute and delivers in the bridge formwork, carries out concreting.
The mobile chassis of building uses view to see accompanying drawing 5,6.
