The two connecting pieces of the utility model are welded on two beam sections to be butted in advance, and the steel box beams can be positioned quickly only by connecting the connecting pieces of the two steel box beams through bolts on site; the bottom of the butt joint device is provided with a welding through hole, and butt welding of the box girder can be continuously carried out, so that the butt joint construction progress is accelerated.
Description
Technical Field
The utility model relates to a steel construction bridge construction technical field, during concretely relates to steel box girder installation, carry out the device that the butt joint was carried out in the adjacent steel box girder location.
Background
In the construction process of the steel structure bridge, the steel box girder is generally processed in sections in a processing field and transported to the field for installation. When the bridge spans the existing road, the underpass road needs to be temporarily closed when the steel box girder is hoisted, so that the requirement on the construction efficiency is high, the hoisting construction time is shortened as much as possible, and the influence on the traffic is reduced to the maximum extent.
The main factors influencing the installation speed of the steel box girder include the sectional positioning speed and the inter-section butt joint speed. When the existing steel box girder is installed, a measurer generally calculates the coordinates of each steel box girder block section according to the coordinates of a bridge to position, and the method consumes long time; when the steel box girder is close to the installation position of the steel box girder in a machining field and the bridge span line position, the steel box girder is generally large in block size, the steel box girder is difficult to level during installation, and after leveling, a stacking plate needs to be welded for fixing and then butt welding is carried out, so that the inter-segment butt joint speed is influenced. Therefore, the existing steel box girder installation method is not beneficial to accelerating the installation construction progress of the steel box girder.
Disclosure of Invention
The utility model aims at providing a to the slow problem of current steel box girder installation positioning speed, provide a positioner that is used for quick butt joint between steel box girder, improve steel box girder butt joint efficiency of construction.
The technical scheme of the utility model as follows:
the utility model provides a quick butt joint positioner of bold section steel case roof beam which characterized in that: the connecting plate is characterized by comprising two connecting pieces, wherein each connecting piece comprises two vertical plates with a certain interval, each vertical plate comprises a horizontal top edge, a horizontal bottom edge, a vertical side edge and an inclined side edge, an arc-shaped notch is formed between the lower end of the vertical side edge and one end of the bottom edge, a connecting plate is welded between the vertical side edges of the two vertical plates, the width of the connecting plate is larger than the interval between the two vertical plates, and two vertically arranged screw holes are respectively formed in the connecting plate between the two vertical plates and at the outer sides of the two vertical plates; the connecting plates of the two connecting pieces are opposite, and the two connecting pieces are connected and fixed through bolt holes in the connecting plates by bolts.
The utility model discloses can weld the connecting piece on steel case roof beam block section in advance at the processing field, the scene only needs to pass through bolted connection with the connecting piece of two steel case roof beams, and steel case roof beam leveling, location are once accomplished, and the interfacing apparatus bottom is equipped with the welding via hole, and the case roof beam butt welding can go on in succession, is favorable to accelerating the butt joint construction progress. The utility model discloses it is low to the steel case roof beam piecemeal requirement, the suitability is strong, is particularly useful for the steel case roof beam butt joint installation of super large-scale block.

Detailed Description
As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, and fig. 6, the present invention includes two connecting members, each connecting member includes two vertical plates 1 with a certain distance therebetween, each vertical plate includes a horizontal top edge and a bottom edge, a vertical side edge and an inclined side edge, an arc notch 2 is disposed between the lower end of the vertical side edge and one end of the bottom edge, a connecting plate 3 is welded between the vertical side edges of the two vertical plates, the width of the connecting plate 3 is greater than the distance between the two vertical plates 1, and two screw holes 31 arranged up and down are respectively disposed on the connecting plate 3 between the two vertical plates and outside the two vertical plates; the connecting plates of the two connecting pieces are opposite, and the two connecting pieces are connected and fixed through bolt holes on the connecting plates by bolts 4.
The utility model discloses during the concrete implementation, can make the overall structure of connecting piece more firm at the reinforcing plate 5 that the welding level set up between the topside of the riser of every connecting piece and link plate.
As shown in fig. 7, the utility model is used for butt joint of steel box girders, when the steel box girders are pre-assembled in the field, two connecting pieces of a butt joint device are respectively welded on the top surfaces of butt joint ends of two steel box girders 6 to be butt jointed, the bottom edge of an erect board 1 of each connecting piece is welded with the top surface of the steel box girder 6, and a connecting board 3 is flush with the end surface of the steel box girder 6; when the steel box girders are transported to a site for hoisting, the connecting pieces at the butt joint ends of the two steel box girders are directly connected through the bolts 4, and the leveling and positioning of the two steel box girders can be quickly completed; the arc 2 notches on the two connecting piece vertical plates are opposite to form a semicircular over-welding hole positioned above the seam 7 of the two steel box girders, and when the two steel box girders are butt-welded, continuous welding can be realized through the over-welding hole, so that the welding construction efficiency is improved, and the butt joint speed of the steel box girders is further accelerated.
