Description
Technical field
The utility model relates to technical field of bridge construction, especially highway simple support-continuous girder work progress
In, temporary support removes operation platform used in work after completing system transform.
Background technique
The structural system of simple supported-to-continuous girder bridge is since its speed of application is fast, at low cost, short time limit, simple process, work
Sequence is few to be most widely used in highway engineering construction field.Superstructure common form has prestress box beam and T beam, plate-girder, beam
Plate uses temporary support when installing first, removes after system transform completion, then by temporary support.Its system transform is continuous
One of beam construction key process, and it is then system transform core work that temporary support, which is removed,.Due to bridge top pier top Cast-in-Situ Segment
It has constructed completion with wet seam, it is usually to use truck crane that construction personnel can not directly remove temporary support from bridge floor to bent cap top
Or set up scaffold under bridge and carry out interim production Demolition Construction, but truck crane is taken a lot of work arduously, construction cost is high, and sometimes under bridge
Do not have the condition of current truck crane；Scaffold construction low efficiency is set up, and part bridge zone does not have scaffold building condition, because
This temporary support remove be presently, there are construction difficult problem.
Summary of the invention
The utility model provides a kind of bridge construction spelling for the problem for lacking security platform when removing temporary support
Formula temporary support removes platform, can guarantee safety, quickly remove temporary support, completes bridge conversion.
The technical solution of the utility model is as follows：
A kind of operation platform removed for bridge temporary support, it is characterised in that：Including movable stand and operating platform；
The movable stand is arranged on bridge floor, including a pedestal, and 4 traveling wheels are arranged in the base bottom, and base top surface is provided with
A vertical bar is respectively set in hoist engine, pedestal two sides, and two vertical bar upper ends are connected by cross bar, and the cross bar is equipped with fixed pulley, institute
The traction rope of hoist engine is stated around sagging after the fixed pulley, the pull rod reserved when lower end is poured by the wet seam in bridge floor center
Hole extends to below bridge floor；The operating platform is located at below bridge floor, and hoist engine traction rope lower end passes through shoulder pole girder connection 4
Root lifting rope, 4 lifting ropes are connect with the two sides of operating platform respectively, and the operating platform both ends extend respectively into bridge floor two sides, and
It is separately connected a ladder.
The utility model structure is simple, and stress is clear, easy to process, and temporary support can be completed without heavy mechanical equipment
Dismounting work.To mountain area simply supported beam, temporary support is removed using the utility model, 1.5 can be saved relative to using truck crane
A machine-team (25 tons of truck cranes) and 6 man-days, economic benefit are obvious.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model direction across bridge；
Fig. 2 be the utility model along bridge to structural schematic diagram.
Specific embodiment
As shown in Figure 1 and Figure 2, the utility model includes movable stand and operating platform, and the movable stand is arranged in bridge floor
On, including a pedestal 1,1 bottom of the pedestal setting, 4 traveling wheels 2,1 top surface of pedestal is provided with hoist engine 3, pedestal two sides point
One vertical bar 4 is not set, and two vertical bars, 4 upper end is connected by cross bar 5, and the cross bar 5 is equipped with fixed pulley 6, and the hoist engine 3 is led
Messenger 7 bypasses sagging after the fixed pulley 6, and reserved tie rod hole extends to bridge when lower end is poured by the wet seam in bridge floor center
8 lower section of face；The operating platform 9 is located at 8 lower section of bridge floor, and 7 lower end of hoist engine traction rope connects 4 by shoulder pole girder 10 and hangs
11,4 lifting ropes 11 of rope are connect with the two sides of operating platform 9 respectively, and 9 both ends of operating platform extend respectively into bridge floor two sides,
And it is separately connected a ladder 12.
When the utility model is used, first completing the assembly of operating platform 9 at bridge bottom, movable stand is mobile by traveling wheel
Hole site is reserved to the wet seam in bridge floor center, and hoist engine traction rope and preformed hole increase limit to just anchoring traveling wheel afterwards
Measure.
After the decentralization to ground of traction rope 7, by 10 attended operation platform of shoulder pole girder, it is flat then to start hoist engine promotion operation
Platform 9 is to appropriate height.
Construction personnel from the two sides of bridge floor by under vertical ladder 12 in operating platform 9, carrying out temporary support and remove to make
Industry.
After operation, construction personnel is back to bridge floor, hoist engine lowering operation platform to ground, solution along vertical ladder
Except connecting with operating platform, then movable stand is moved to next setting construction.
To guarantee construction safety, after operating platform is promoted in place, a shelf bracket can be connected in 12 upper end of ladder
13, the shelf bracket 13 is flexibly connected by pin shaft with ladder, and is supported on bridge floor 8.
Independent lifting rope stress switchs to both sides shelf bracket and the common stress of intermediate lifting rope when total is by being promoted at this time, only
People can be gone up after shelf bracket support in two sides falls on position by, which having, starts to remove operation to operating platform, improves the construction of total
Safety.
