Description

Continuous beam cantilever concreting 0# piece bracing or strutting arrangement
Technical field: the invention is to be used for the device that the bridge engineering cantilever pouring reinforced concrete continuous beam 0# piece in crossing highway, railway or river supports.
Background technology: along with the application of technological progress and new material, the concrete continuous beam of large span is widely used in the bridge engineering in crossing highway, railway, river.In continuous beam cantilever pouring construction process, the 0# piece is the counter-force application point of Hanging Basket and the job platform that Hanging Basket is installed as the girder construction on Dun Ding top.The concrete of 0# piece must be built on the rack platform of setting up.According to former job practices, operation platform adopts steel pipe support, support is set up on the cushion cap or the concrete foundation of temporarily building, the timbering material that this method is used is many, and be only applicable to highly lower bridge, very uneconomical for high pier bridge steel pipe holder, and set up difficulty, stiffness of support is difficult to guarantee.
Summary of the invention: the purpose of the invention provides a kind of saving timbering material, sets up continuous beam cantilever concreting 0# piece bracing or strutting arrangement easily; The purpose of the invention is to realize by following technical scheme: continuous beam cantilever concreting 0# piece bracing or strutting arrangement is characterized in that being made up of shelf bracket i iron horizon bar, shelf bracket i iron diagonal brace, upright steel plate, plain plate, pre-embedded steel slab, finish rolling deformed bar, steel case, reinforcement steel plate II, embedded bar, steel mesh reinforcement, pvc pipe, reinforcement steel plate, reinforcement steel plate I, the perpendicular support of shelf bracket channel-section steel and shelf bracket channel-section steel diagonal brace; Three upright steel plates and plain plate be welded into a whole to be welded on the pre-embedded steel slab again, and embedded bar is welded on the pre-embedded steel slab, and steel mesh reinforcement and pre-embedded steel slab parallelization are formed pre-buried support for three layers; Shelf bracket i iron horizon bar, shelf bracket i iron diagonal brace, the perpendicular support of shelf bracket channel-section steel are become shelf bracket with shelf bracket channel-section steel diagonal brace assembly welding, on shelf bracket i iron horizon bar, strengthen steel plate and strengthen steel plate I with shelf bracket i iron diagonal brace and the welding of both sides, shelf bracket channel-section steel diagonal brace contact position; Per four finish rolling deformed bars are one group, and totally four groups, suit pvc pipe on every finish rolling deformed bar at every group of finish rolling deformed bar one end dress steel case, is strengthened steel plate II at other end dress; The steel case of every group of finish rolling deformed bar two ends dress and strengthen steel plate II respectively with shelf bracket in the welding of shelf bracket i iron horizon bar, the shelf bracket i iron diagonal brace in the shelf bracket welds with the plain plate in the pre-buried support.
The advantage of the invention: this device does not take space under the bridge, and material therefor is few than the steel pipe support consumption, and features simple structure is easy to install, dismantle.
Description of drawings:
Fig. 1 is a continuous beam cantilever concreting 0# piece support device structure schematic diagram;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1;
Fig. 3 is steel case and the finish rolling deformed bar scheme of installation in the continuous beam cantilever concreting 0# piece bracing or strutting arrangement.
Among the figure: 1,0# block concrete 2, support chock 3, shelf bracket i iron horizon bar 4, pier cap 5, shelf bracket i iron diagonal brace 6, upright steel plate 7, plain plate 8, pre-embedded steel slab 9, finish rolling deformed bar 10, steel case 11, reinforcement steel plate II 12, embedded bar 13, steel mesh reinforcement 14, pvc pipe 15, pier shaft 16, reinforcement steel plate 17, reinforcement steel plate I 18, shelf bracket channel-section steel diagonal brace 19, shelf bracket channel-section steel erect support
The specific embodiment: continuous beam cantilever concreting 0# piece bracing or strutting arrangement is characterized in that being made up of shelf bracket i iron horizon bar, shelf bracket i iron diagonal brace, upright steel plate, plain plate, pre-embedded steel slab, finish rolling deformed bar, steel case, reinforcement steel plate II, embedded bar, steel mesh reinforcement, pvc pipe, reinforcement steel plate, reinforcement steel plate I, the perpendicular support of shelf bracket channel-section steel and shelf bracket channel-section steel diagonal brace; Three upright steel plates and plain plate be welded into a whole to be welded on the pre-embedded steel slab again, and embedded bar is welded on the pre-embedded steel slab, and steel mesh reinforcement and pre-embedded steel slab parallelization are formed pre-buried support for three layers; Shelf bracket i iron horizon bar, shelf bracket i iron diagonal brace, the perpendicular support of shelf bracket channel-section steel are become shelf bracket with shelf bracket channel-section steel diagonal brace assembly welding, on shelf bracket i iron horizon bar, strengthen steel plate and strengthen steel plate I with shelf bracket i iron diagonal brace and the welding of both sides, shelf bracket channel-section steel diagonal brace contact position; Per four finish rolling deformed bars are one group, and totally four groups, suit pvc pipe on every finish rolling deformed bar at every group of finish rolling deformed bar one end dress steel case, is strengthened steel plate II at other end dress; The steel case of every group of finish rolling deformed bar two ends dress and strengthen steel plate II respectively with shelf bracket in the welding of shelf bracket i iron horizon bar, the shelf bracket i iron diagonal brace in the shelf bracket welds with the plain plate in the pre-buried support.
According to being applied as example at Shahe, Harbin-to-Dalian Line for Passenger Transportation north grand bridge: shelf bracket i iron horizon bar and shelf bracket i iron diagonal brace can be made with i iron, make horizon bar with the I56 i iron, and with I40 I-shaped steel diagonal brace, the long 5.5m of horizon bar, diagonal brace are 5.0m; Perpendicular support of shelf bracket channel-section steel and shelf bracket channel-section steel diagonal brace can be used] 40 channel-section steel manufacturings; Embedded bar is made long 0.5m with Φ 25 finish rolling deformed bars, and the embedded bar arrangement pitches is 0.1m; Embedded bar and pre-embedded steel slab are welded as the bilateral weldering, and every side weld length is not less than 5cm; Compound steel muscle net is set, and every layer of steel mesh reinforcement made with Φ 10 round bars; Its effect is to prevent that the pier shaft concrete is by local pressure break; The steel case is made the uncovered casing,, the steel box structure is of a size of 0.66m * 0.4m * 0.2m, adopts the thick steel plate welding fabrication of 20mm; Finish rolling deformed bar adopts Φ 32 finish rolling deformed bar manufacturings; Pvc pipe adopts Φ 50mm pipe; Strengthening steel plate makes with the 2cm steel plate with reinforcement steel plate I.
This device of utilization is that embedded bar and steel mesh reinforcement that the pre-buried support in this device promptly constitutes pre-buried support are embedded in the pier shaft in engineering construction; The finish rolling deformed bar that is with pvc pipe is embedded in the pier cap, and the 0# block concrete has been built detachable this device in back, and finish rolling deformed bar is removed from pier cap, and mud jacking is carried out in the duct.
