Background technology
At present, along with expanding economy, the scale of China's urban infrastructure is increasing, and overhead road of city, grade separation are not only promoting the traffic ability in city, also becomes the view of beauty together in city.Superstructure is heavy in section fish-belly continuous box beam, with the cross section line style of its grace, novel outward appearance, by more overhead road of city, adopted gradually, but its profile and stressed comparatively complicated is if adopt traditional steel tube fastener to set up, time-consuming, construction error large but also affect the perception of concrete surface, in addition, conventionally below case beam, all can adopt scaffold to support, still, setting up of scaffold affects its stability.
Utility model content
The utility model provides a kind of sharp radius curve fish-belly continuous box beam.
The technical solution of the utility model is: a kind of sharp radius curve fish-belly continuous box beam, comprise bottom die of box-beam, bed die support, bowl fastening type support and concrete bottom, described bed die support comprises cambered surface and steelframe, described bottom die of box-beam is arranged in cambered surface, and described cambered surface is identical with bottom die of box-beam circular-arc bottom face radian, described cambered surface surface is evenly equipped with longitudinal lumps of wood, described bed die support is connected by adjustable jacking with bowl fastening type support, described bowl fastening type support lower end is provided with adjustable collet, and bowl fastening type support is arranged on concrete bottom by adjustable collet.
Preferably, described cambered surface is channel-section steel cambered surface.
Preferably, described bottom die of box-beam adopts bamboo offset plate to be spliced.
Preferably, the interlude of described cambered surface is straightway, and both sides are arc section, and straightway is connected with two sections of arc sections with screw by flange.
Preferably, described steelframe is made by square steel.
Preferably, cambered surface is welded on steelframe.
The beneficial effects of the utility model: the utility model is simple in structure, low cost of manufacture; Practical, steel concrete fish-bellied type bottom die of box-beam integral construction, reduces constructor and drops into, increase work efficiency, in addition, adopt the enhancing of bowl fastening type support stability, good integrity, the use of adjustable collet and adjustable jacking can meet the height of adjustment up and down of support integral body.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fish-belly continuous box beam;
Fig. 2 is the structural representation of bottom die of box-beam in the utility model;
In figure: 1 bottom die of box-beam, 2 bed die supports, 3 bowl fastening type supports, 4 concrete bottoms, 5 lumps of wood, 6 adjustable jackings, 7 adjustable collets, 8 cambered surfaces, 9 steelframes, 10 flitches.
The specific embodiment
The embodiment by reference to the accompanying drawings the utility model being provided is described in further detail:
As Fig. 1, shown in 2, a kind of sharp radius curve fish-belly continuous box beam of the utility model, comprise bottom die of box-beam 1, bed die support 2, bowl fastening type support 3 and concrete bottom 4, described bed die support 2 comprises cambered surface 8 and steelframe 9, described bottom die of box-beam 1 is arranged in cambered surface 8, and described cambered surface 8 is identical with bottom die of box-beam 1 circular-arc bottom face radian, described cambered surface 8 surfaces are evenly equipped with longitudinal lumps of wood 5, described bed die support 2 is connected by adjustable jacking 6 with bowl fastening type support 3, described bowl fastening type support 3 lower ends are provided with adjustable collet 7, bowl fastening type support 3 is arranged on concrete bottom 4 by adjustable collet 7.
Wherein, bottom die of box-beam 1 is spliced for bamboo offset plate, cambered surface 8 is welded on steelframe 9, the interlude of described cambered surface 8 is straightway, and both sides are arc section, and straightway is connected with two sections of arc sections with screw by flange, wherein, described cambered surface 8 is channel-section steel material, can strengthen holding capacity, and steelframe 9 is made by square steel.
The cambered surface 8 of bed die support 2 of the present utility model is to be stamped to form by 80 type channel-section steels, and steelframe 9 is to be welded with the square steel pipe ribbing of 50*50*2.5 mm, and steelframe 9 is comprised of three of the straightways at the bottom of two segmental arcs and case altogether, with flange, is connected with bolt.Along distribute spacing is identical with bowl fastening type support 3 vertical rod longitudinal pitches along the bridge, 3 vertical rods of the rim of a bowl cribbing adopt the spacing of 0.9*0.9m, step pitch 1.2m.
3 vertical rods of bowl fastening type support all adopt up and down adjustable top, collet, on adjustable jacking 6, cambered surface 8 is installed, in cambered surface 8, vertical bridge is to laying the cross section 10*10*400cm lumps of wood 5, on the lumps of wood 5 fixedly 2440*1220*15mm bamboo offset plate as bottom die of box-beam 1, it has advantages of that rigidity is large, easy construction, the number of turnover is many, speed of application is fast, is equipped with the flitch 10 of 5*20cm below adjustable collet 7.
Vertical rod base top, the liftoff 20cm of being not more than place adds the horizontal and vertical bar of sweeping the floor, and 4m spacing arranges vertical and horizontal direction shearing support, to guarantee the resistance to overturning of support.
In this manual, the utility model is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, manual and accompanying drawing are regarded in an illustrative, rather than a restrictive.
