Description
Technical Field
The utility model belongs to the technical field of bridge steel structure processing, a steel pipe arch bridge's arch rib processing is related to, concretely relates to bed-jig is assembled to steel pipe arch rib.
Background
The arch rib of the steel tube arch bridge is processed by adopting a horizontal splicing method, and the arch rib is usually spliced in sections on a jig frame. Because the steel pipe arch rib is arc-shaped, and the corresponding line shapes of the arch ribs with different spans have larger difference, corresponding moulding beds need to be erected aiming at the arch ribs with different line shapes in the arch rib manufacturing process at present, a large amount of construction sites are occupied, and the construction cost is greatly increased.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a bed-jig is assembled to steel pipe arch rib with adjustable is provided, makes a bed-jig applicable in multiple arch rib processing to practice thrift construction cost.
The technical scheme of the utility model as follows:
the utility model provides a bed-jig is assembled to steel pipe arch rib with adjustable, includes 3 parallel arrangement's arc girder, and every girder bottom is established a landing leg at every fixed interval, and girder top surface welds one at every fixed interval and spanes the distribution roof beam of 3 girders, its characterized in that: a sliding groove is longitudinally formed in the top surface of each distribution beam, two limiting blocks capable of sliding along the sliding groove are arranged on each distribution beam, an arch rib positioning plate capable of sliding along the sliding groove is arranged between the two limiting blocks, and an arc-shaped arch rib clamping groove is formed in the middle of the arch rib positioning plate.
The utility model discloses the commonality is strong, through the line type of the different arch ribs of position adaptation of each arch rib locating plate on the adjustment bed-jig, a bed-jig can be used to the processing of multiple arch rib, can reduce construction cost by a wide margin.

Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a 3 parallel arrangement's arc girder 1, a landing leg 2 is established at every fixed interval in every girder 1 bottom, girder top surface welding one span 3 distribution beam 3 of girder at fixed interval, a spout 4 is vertically established along 3 top surfaces of every distribution beam, be equipped with two on the distribution beam and follow the gliding stopper 5 of spout, be equipped with between two stoppers 5 and follow gliding arch rib locating plate 6 of spout, be equipped with curved arch rib draw-in groove 7 in the middle of the arch rib locating plate 6.
As shown in fig. 4 and 5, flange plates are respectively arranged on two sides of the top of the distribution beam 3. The utility model discloses during the concrete implementation, the distribution beam can adopt two channel-section steels preparation, and the wainscot of two channel-section steels is relative and have certain clearance, through steel sheet welding between two channel-section steel wainscot lower halves, and the clearance between the first one of two channel-section steels wainscot is as the spout, and the leg board on two channel-section steels upper portion is as the flange board.
The limiting block 5 comprises a top plate 51, bayonets 52 clamped at two sides of the flange plate of the distribution beam are arranged at the bottoms of two sides of the top plate, a bolt 53 vertically penetrates through the middle of the top plate, and the lower end of the bolt 53 is inserted into the sliding groove 4 of the distribution beam 3. And the positioning bolt is screwed down, so that the lower end of the positioning bolt is abutted against the bottom of the sliding groove, the limiting block can be fixed with the distribution beam, the positioning bolt is loosened, and the limiting block can slide along the sliding groove.
When the utility model is implemented, the arch rib positioning plate 6 can adopt a steel plate, and an arch rib clamping groove is arranged in the middle; the arch rib positioning plates can also be arranged into two blocks, the bottom edges of the two arch rib positioning plates are supported in the sliding grooves, each arch rib positioning plate has a structure shown in figure 6, and one end of the top edge of each arch rib positioning plate is provided with an arc-shaped edge 61 which is bent downwards. As shown in fig. 3, the arc ends of the two arch rib positioning plates 6 are opposite to each other to form an arch rib clamping groove 7; the two sliding limiting blocks are respectively arranged at the other ends of the two arch rib positioning plates. The two arch rib positioning plates have the advantages that the distance between the two arch rib positioning plates can be adjusted, and the arch rib positioning device is better suitable for positioning arch ribs with different diameters.
When the utility model is used, the positioning bolt of the limiting block is firstly loosened, so that the limiting block can freely slide; and then, adjusting the position of the arch rib positioning plate on each distribution beam according to the line type of the arch rib, and after the arch rib positioning plate is adjusted in place, screwing the positioning bolts of the limiting blocks to fix the position of the arch rib positioning plate. The rib segments 8 are then placed into the rib slots 7 on the rib alignment plate as shown in fig. 7 and 1.
