Abstract
The utility model relates to a device for installing a bottom sealing plate of a cantilever arm of a steel box girder, which comprises two longitudinal beams, wherein at least two cross beams are welded between the two longitudinal beams; two supporting blocks are welded at one end, close to the top surface of each longitudinal beam, the top surfaces of 4 supporting blocks on the two longitudinal beams are positioned on the same plane, and under the condition that the longitudinal beams are in the horizontal state, the included angle between the plane where the top surfaces of the 4 supporting blocks are positioned and the horizontal plane is consistent with the installation angle of the steel box beam cantilever arm sealing plate; a baffle plate vertical to the top surface of the longitudinal beam is welded between the top surfaces of the other ends of the two longitudinal beams, and a balancing weight is fixedly arranged between the top surfaces of the two longitudinal beams close to the inner side of the baffle plate; two lifting lugs with a certain distance are welded on the top surface of each longitudinal beam close to the middle of the longitudinal beam. The sealing plates are welded on the 4 supporting blocks temporarily, and the sealing plates are lifted to the mounting positions of the sealing plates below the cantilever arms by the automobile crane connecting lifting lugs to be welded without being limited by ground conditions and the height of a bridge.
Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a steel case roof beam's installation construction is related to, concretely relates to a device for installing steel case roof beam outrigger bottom shrouding.
Background
When the steel box girder is processed, the position of a sealing plate can be reserved at the bottom of the cantilever arm of the steel box girder, and after the steel box girder is installed on a bridge, the last sealing plate is welded. When the construction bridge is located in plain or the comparatively flat region of relief, the shrouding can adopt the mode of falling to the ground support + operation platform mode to weld, but in the complicated region of topography such as mountain, canyon, the steel box girder is higher apart from ground, erects the support cost higher, and is difficult for erectting, therefore the installation of cantilever shrouding is a difficult problem.
Disclosure of Invention
The utility model aims at the above-mentioned problem, a steel box girder outrigger bottom shrouding installation device is provided, does not receive the ground condition restriction, guarantees that shrouding installation and construction goes on smoothly.
The technical scheme of the utility model as follows:
the utility model provides a steel case roof beam outrigger bottom shrouding installation device which characterized in that: the cantilever arm bottom sealing plate comprises two longitudinal beams, wherein the two longitudinal beams are parallel to each other and have a distance not larger than the width of the cantilever arm bottom sealing plate, and at least two cross beams are welded between the two longitudinal beams; two supporting blocks are welded at the top surface of each longitudinal beam close to one end, a certain distance is reserved between each two supporting blocks along the longitudinal direction of the longitudinal beam, the top surfaces of 4 supporting blocks on the two longitudinal beams are positioned on the same plane, and the included angle between the plane where the top surfaces of the 4 supporting blocks are positioned and the horizontal plane is consistent with the installation angle of the steel box beam cantilever arm sealing plate when the longitudinal beam is in the horizontal state; a baffle plate vertical to the top surface of the longitudinal beam is welded between the top surfaces of the other ends of the two longitudinal beams, and a balancing weight is fixedly arranged between the top surfaces of the two longitudinal beams close to the inner side of the baffle plate; two lifting lugs with a certain distance are welded on the top surface of each longitudinal beam close to the middle of the longitudinal beam.
The utility model discloses a truck crane lifts by crane, and the support need not set up to the arm shrouding is picked in the installation, does not receive the restriction of construction area ground condition and bridge height, and construction cost is low, and is fast.

Detailed Description
As shown in fig. 1 and 2, the present invention comprises two longitudinal beams 1, the two longitudinal beams are parallel to each other and have a distance not larger than the width of the bottom sealing plate of the cantilever arm, and at least two cross beams 2 are welded between the two longitudinal beams; two supporting blocks 3 are welded at the top surface of each longitudinal beam close to one end, a certain distance is reserved between each two supporting blocks along the longitudinal direction of the longitudinal beam, the top surfaces of 4 supporting blocks on the two longitudinal beams are positioned on the same plane, and the included angle between the plane where the top surfaces of the 4 supporting blocks are positioned and the horizontal plane is consistent with the installation angle of the steel box beam cantilever arm sealing plate when the longitudinal beam is in the horizontal state; a baffle 4 vertical to the top surface of the longitudinal beam is welded between the top surfaces of the other ends of the two longitudinal beams, and a balancing weight 5 is fixedly arranged between the top surfaces of the two longitudinal beams close to the inner side of the baffle; two lifting lugs 6 with a certain distance are welded on the top surface of each longitudinal beam close to the middle of the longitudinal beam.
As shown in fig. 3, when the cantilever sealing plate of the present invention is welded, the bottom surface of the sealing plate 7 is welded with 4 supporting blocks 3 on two longitudinal beams on the ground or bridge surface, an automobile crane is adopted to hoist through 4 lifting lugs 6 on the two longitudinal beams, and the weight of the balancing weight 5 is adjusted to keep the longitudinal beam 1 horizontal in the hoisted state, so as to hoist the sealing plate to the sealing plate mounting position below the cantilever of the steel box girder 8; as shown in fig. 4, a constructor performs closing plate welding construction on the steel box girder cantilever welding platform 9; as shown in fig. 5, after the sealing plate is welded, the sealing plate is cut to be connected with the supporting block 3, so as to lift the utility model back to the ground or the bridge floor.
