Description
Technical Field
The utility model belongs to the technical field of bridge construction, relates to construction of a double-width bridge or a multi-width bridge, and particularly relates to a movable construction platform for construction between bridge widths.
Background
The beam body of a bridge usually comprises a main body and cantilevers on both sides of the main body. When the bridge is constructed, a bridge main body is generally installed or poured firstly, and then cantilever construction is carried out on two sides. For a steel structure bridge, welding of a cantilever and a main box girder needs to be carried out under the bridge, and for a cast-in-place concrete beam, cantilever pouring templates need to be placed and installed on two sides of the main box girder. In general, a vehicle such as a lift car or a crane is used as a construction platform under a bridge for cantilever construction. For a double-amplitude bridge or a plurality of bridges, certain gaps are usually reserved among the bridges, but the gaps are narrow and limited by traffic conditions, so that vehicles are inconvenient to move under the bridges, and the construction progress is influenced.
Disclosure of Invention
The utility model aims to solve the problems and provides a movable construction platform for construction between bridge panels, so that the construction efficiency of a bridge cantilever is improved.
The technical scheme of the utility model is as follows:
the utility model provides a movable construction platform that is used for construction between bridge width of cloth which characterized in that: the device comprises a frame beam and an operating platform positioned below the frame beam, wherein the frame beam is connected with the operating platform through a hanging rod; the frame beam comprises two upper longitudinal beams which are arranged in parallel, two upper cross beams which are arranged in parallel are welded between the two ends of the two upper longitudinal beams, and the bottoms of the two ends of each upper longitudinal beam are respectively provided with a roller; the operating platform comprises two lower cross beams which are arranged in parallel and have a distance smaller than the width distance of the two bridges, a plurality of platform supporting rods are welded between the two lower cross beams, and a platform panel is laid on the platform supporting rods; two upper crossbeams of the frame beam are respectively welded with two lower crossbeams of the operation platform, and a ladder climbing step bar is welded between the two upper crossbeams and the two lower crossbeams welded with the lower crossbeams at certain intervals.

Detailed Description
As shown in fig. 1 and 2, the present invention comprises a frame beam 1 and an operation platform 2 located below the frame beam, wherein the frame beam and the operation platform are connected by a suspension rod 3.
The structure of the frame beam 1 is shown in fig. 3, and comprises two upper longitudinal beams 11 arranged in parallel, two upper transverse beams 12 arranged in parallel are welded between two ends of the two upper longitudinal beams, and the bottom of two ends of each upper longitudinal beam 12 is respectively provided with a roller 13.
The structure of the operating platform 2 is shown in fig. 4, and comprises two lower beams 21 which are arranged in parallel and have a distance smaller than the width distance between the two bridges, a plurality of platform support rods 22 are welded between the two lower beams, and platform panels 23 are laid on the platform support rods.
Two suspenders 3 are respectively welded between two upper crossbeams 12 of the frame beam 1 and two lower crossbeams 21 of the operating platform 2, and a ladder climbing step bar 4 is welded between the two suspenders 3 welded on each upper crossbeam and each lower crossbeam at certain intervals.
In the specific implementation of the utility model, in order to ensure the balance of the operation platform, the centers of the upper beam 12 and the lower beam 21 of the two suspenders 3 welded on each upper beam and each lower beam are symmetrically arranged.
In the specific implementation of the utility model, a plurality of connecting rods 14 can be welded between the two upper cross beams 11 of the frame beam for reinforcing the structure of the frame beam.
In the specific implementation of the utility model, in order to ensure the construction safety, a platform guardrail 5 can be welded on the periphery of the operating platform 2.
In the specific implementation of the utility model, in order to ensure the connection strength of the operating platform and the hanger rods, a diagonal brace 6 can be welded between each hanger rod 3 and the lower cross beam 21.
When the utility model is implemented, the length of the frame beam is larger than the distance between the two bridge main body box beams.
As shown in fig. 5 and 6, when the utility model is used, a crane is used for hoisting the operation platform 2 between two bridges, the operation platform is firstly placed under the bridge along the gap between the two bridges 7, when the frame beam 1 approaches the bridge surface, the whole construction platform is rotated by 90 degrees, then the rollers 13 at the two ends of the frame beam 1 are respectively supported on the main box beams of the two bridges, and constructors can descend from the bridge to the operation platform 2 through the ladder climbing step bars 4. For the steel structure bridge, the bottom welding construction can be carried out on the cantilevers of the two bridges on the operation platform; for the construction of the concrete cantilever of the cast-in-place beam, a lower template of the cantilever can be installed and disassembled on the operating platform. After one station construction is completed, the construction platform is pushed to move to the next construction position on the bridge.
