Description
Technical Field
The utility model belongs to the technical field of the construction of steel construction bridge, a processing of steel case roof beam is related to, in the welding process of concretely relates to steel case roof beam cross slab and bottom plate for support the cross slab and adjust its straightness's that hangs down device.
Background
The steel box girder comprises a bottom plate and a top plate, and a plurality of transverse clapboards vertical to the bottom plate are arranged between the bottom plate and the top plate. In the steel box girder machining process, the bottom edge of the partition plate is welded with the top surface of the bottom plate, and the perpendicularity of the partition plate and the bottom plate is guaranteed in the welding process. The existing construction method is that before the partition board is welded, after the verticality of the partition board is adjusted, the bottom board and the partition board are fixed through temporary spot welding by the support rod, so that the partition board and the bottom board are not displaced or inclined in the welding process, and after the welding is finished, the support rod is cut off. This kind of mode can cause the damage to cross slab, bottom plate, needs the secondary coping, in case the straightness that hangs down appears the deviation moreover, is difficult for adjusting.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a steel case roof beam cross slab supports and straightness adjusting device that hangs down is provided, adopts assembled mounting structure, avoids causing the damage to steel case roof beam bottom plate and baffle to can adjust the straightness that hangs down of baffle in a flexible way when the welding.
The technical scheme of the utility model as follows:
the utility model provides a steel case roof beam diaphragm supports and straightness adjusting device that hangs down which characterized in that: the bolt comprises a turn buckle, wherein one end of the turn buckle is welded with a first U-shaped clamping sleeve, and the other end of the turn buckle is welded with a second U-shaped clamping sleeve; each U-shaped cutting sleeve comprises a rectangular top plate and two side plates, and two sides of the top plate are respectively welded with the top edges of the two side plates; the outer side of one side plate of the first U-shaped clamping sleeve is welded with one end of the turn buckle, an acute included angle is formed between the outer side of one side plate of the first U-shaped clamping sleeve and the axis of the turn buckle, and the distance between the two side plates is equal to the thickness of the steel box girder diaphragm; a top plate of the second U-shaped clamping sleeve is welded with the other end of the turnbuckle, the distance between two side plates is larger than or equal to the width of a rib on the top surface of the bottom plate of the steel box girder, and two positioning bolts vertical to the side plates are respectively penetrated through the two side plates; the side plate of the first U-shaped cutting sleeve is vertical to the side plate of the second U-shaped cutting sleeve.
The utility model adopts the turn buckle as the support rod, and utilizes the ribs on the bottom plate of the steel box girder to install and fix to support the baffle plate, thereby avoiding the damage to the bottom plate and the baffle plate; can adjust and guarantee the straightness that hangs down of baffle through the length of adjusting the bracing piece. The utility model discloses repeatedly usable practices thrift the cost.

Detailed Description
As shown in fig. 1 and 2, the utility model comprises a turn buckle 1, one end of which is welded with a first U-shaped cutting sleeve 2, and the other end is welded with a second U-shaped cutting sleeve 3; each U-shaped cutting sleeve comprises a rectangular top plate and two side plates, and two sides of the top plate are respectively welded with the top edges of the two side plates; the outer side of one side plate of the first U-shaped clamping sleeve 2 is welded with one end of the turn buckle 1, an acute included angle is formed between the outer side of one side plate and the axis of the turn buckle, and the distance between the two side plates is equal to the thickness of a steel box girder diaphragm; a top plate of the second U-shaped clamping sleeve 3 is welded with the other end of the turnbuckle 1, the distance between two side plates is larger than or equal to the width of a rib on the top surface of the bottom plate of the steel box girder, and two positioning bolts 4 vertical to the side plates are respectively penetrated through the two side plates; the side plate of the first U-shaped cutting sleeve is vertical to the side plate of the second U-shaped cutting sleeve.
The turn buckle is a commonly used length adjusting device, which comprises a double-head nut, two ends of which are respectively screwed with a screw rod, and the two screw rods can be adjusted to be stretched and contracted simultaneously by rotating the double-head nut in the middle. The utility model discloses utilize this characteristic of turn buckle, support its straightness that hangs down and adjust it as the bracing piece to the cross slab.
The steel box girder bottom plate top surface all is equipped with many ribs in the same direction as the bridge usually, the utility model discloses utilize the rib on the bottom plate to fix.
As shown in fig. 3, 4 and 5, the utility model is used for during steel box girder diaphragm and bottom plate welding construction, with 2 cards of first U type cutting ferrule on the top edge of steel box girder diaphragm 5, detain second U type cutting ferrule 3 on rib 7 of 6 top surfaces of steel box girder bottom plate, second U type cutting ferrule can follow the rib and slide from beginning to end. After the perpendicularity of the transverse partition plate and the bottom plate is adjusted, the positioning bolts 4 on the two side plates of the second U-shaped clamping sleeve are screwed down, the second U-shaped clamping sleeve is fixed by means of the friction force of the front ends of the positioning bolts 4 and the two sides of the rib 7, the transverse partition plate is supported by means of the turn buckle 1, and then welding construction of the transverse partition plate and the bottom plate is carried out. In the welding process, if the perpendicularity of the diaphragm plate is found to have deviation, the perpendicularity of the diaphragm plate can be finely adjusted by adjusting the length of the turn buckle 1.
And after the welding of one diaphragm plate is finished, the supporting and verticality adjusting device is taken down for recycling.
