Description
Technical field
The utility model relates to bridge support equipment field, the assembled positioning plate device of especially a kind of steel box girder segment.
Background technology
In bridge steel structure, due to the requirement of using function and bearing capacity, increasing steel case bridge to large span, heavy in section future development, but because of the restriction of the factors such as transport and crane gear, generally steel case bridge is divided in produce in factory according to sections, then is transported to building-site and carries out spelling welding.Because steel box-girder cross section is large, tonnage heavy, construction site condition is complicated, in lifting with splicing, casing easily misplaces, and adds distortion during welding, causes steel box girder construction Quality Down, and intensity reduces.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of when preventing steel box-girder welding each sections there is the assembled positioning plate device of steel box girder segment of dislocation.
The utility model solves the technical scheme that its technical problem adopts: the assembled positioning plate device of steel box girder segment, comprises location structure, and described location structure comprises base plate and riser, and described riser is arranged on base plate; Described location structure is arranged in pairs, and is connected as a single entity by syndeton between two risers.
Further, described location structure is L-shaped, and each base plate arranges one end of riser towards another base plate.
Further, be provided with adjustable plate between two risers, fit with two risers respectively in described adjustable plate two sides in a thickness direction, and described adjustable plate is connected as a single entity by syndeton and two risers.
Further, stiffener is provided with between described base plate and riser.
Further, described syndeton is bolt.
The beneficial effects of the utility model are: after two sections of steel box-girder contrapositions, splicing well, by two location structures with the segmented line of steel box-girder for axis of symmetry, be welded on symmetrically on two sections of steel box-girder, and connect two risers by syndeton, make two location structures be connected as a whole with two sections of steel box-girder.When steel box-girder lifting and welding, under the connection function of location structure, can prevent from occurring dislocation between two sections of steel box-girder or being out of shape larger situation, guarantee intensity and the construction quality of steel box-girder.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, Figure 2, Figure 3 shows, the assembled positioning plate device of steel box girder segment of the present utility model, comprises location structure, and described location structure comprises base plate 1 and riser 2, and described riser 2 is arranged on base plate 1; Described location structure is arranged in pairs, and is connected as a single entity by syndeton 3 between two risers 2.
Base plate 1 can adopt the rectangular steel plates of 16 × 110 × 220, and riser 2 adopts the rectangular steel plates of 10 × 150 × 220, is welded to connect between base plate 1 and riser 2.During use, first by two sections of steel box-girder 5 accurately, fitly docking forms segmented line 51, then with segmented line 51 for axis of symmetry, two location structures is placed on the both sides of segmented line 51, centering, levelling, makes the riser 2 of location structure just to the riser 2 of another location structure; Again two base plates 1 are welded on two sections of steel box-girder 5, finally utilize syndeton 3 to connect into as a whole by two risers 2.Along the multipair location structure of segmented line 51 uniform welding, add the intensity of strong fix, guarantee the stable of location.Utilize this device to make two sections of steel box-girder 5 indirectly be connected as a single entity, in lifting and welding process, due to the constraint of location structure between two ends steel box-girder 5, there will not be dislocation and larger distortion, thus guarantee intensity and the construction quality of steel box-girder.After steel box-girder 5 welding completes, remove syndeton 3, and base plate 1 is cut down.
Location structure can be T-shaped, and in order to strengthen the bonding strength between location structure, preferably, described in two, location structure is L-shaped, and each base plate 1 arranges one end of riser 2 towards another base plate 1.When having dislocation motion or deformation tendency between two sections of steel box-girder 5, syndeton 3 can be subject to the active force perpendicular to steel box-girder 5, and the span of syndeton 3 is larger, and the moment of syndeton 3 pairs of risers 2 is larger, span is less, and the moment of syndeton 3 pairs of risers 2 is less.The L-shaped setting of location structure, after two base plates 1 are welded on steel box-girder 5, the distance between two risers 2 is minimum, and therefore, the moment of syndeton 3 pairs of risers 2 is minimum, makes this device have larger supporting capacity.
When base plate 1 is welded on steel box-girder 5, in order to ensure the positional precision between two location structures, preventing riser 2 to be out of shape causes two risers 2 not parallel, preferably, adjustable plate 4 is provided with between two risers 2, fit with two risers 2 respectively in described adjustable plate 4 two sides in a thickness direction, and described adjustable plate 4 is connected as a single entity by syndeton 3 and two risers 2.Length and the width of the length of adjustable plate 4 and width and riser 1 are consistent, and thickness is determined according to the size of steel box-girder 5.When positioning two location structures, the center line of adjustable plate 4 bottom surface is overlapped with segmented line 51, then the riser 2 of two location structures is close to two sides of adjustable plate 4 respectively, then base plate 1 is welded.The symmetry of two location structures can be ensured; When carrying out steel box-girder 5 and lifting or weld, two riser 2 uniform force, stability is better.After steel box-girder 5 welding completes, remove syndeton 3 and adjustable plate 4, base plate 1 is cut down, then partial segments line 51 repair welding covered by former adjustable plate 4 is put in place.
In order to improve the structural strength of location structure, between described base plate 1 and riser 2, be provided with stiffener 13.
The junction plate that syndeton 3 can adopt the combination of screw mandrel and nut, bearing pins or weld, conveniently regulate the distance between two risers 2, as preferred technical scheme, described syndeton 3 is bolt.The bonding strength of bolt is high, can the bulk strength of assurance device, and is installed on convenient disassembly, is conducive to improving efficiency of construction, reduces construction cost.
