Description

Steel box bridge installation auxiliary platform

technical field

The invention relates to a steel box bridge installation auxiliary platform, in particular to a steel box bridge installation auxiliary platform used in the field of steel box bridge installation.

Background technique

With the continuous increase of the span of steel box bridges and the rapid development of installation technology, large-span steel box bridges are manufactured in blocks and sections at the factory according to the lifting capacity of the crane and transportation conditions, and then pre-assembled on site. At the construction site, there will be a large number of small electric welding machines, oxygen cylinders, acetylene cylinders and other tooling and equipment that need to be placed, and when docking at high altitudes, operators will paste ceramic liners at the bottom of the bridge, welding, grinding, and painting. In the prior art, operators are used to directly perform padding, welding, grinding, and repainting operations on long-span steel box bridges. The aforementioned construction operations are high-altitude, high-risk operations, lack of safety facilities, and high-altitude operations are difficult and efficient. Low cost, long working hours, and there is not enough space for tooling such as small electric welding machines, oxygen cylinders, acetylene cylinders, etc., which brings great inconvenience to the installation of steel box bridges. Therefore in the prior art there is not a steel box bridge installation auxiliary platform that is simple in structure, easy to disassemble, can be reused, improves work efficiency while reducing labor and construction costs, and reduces the safety risk of high-altitude operations.

Contents of the invention

The technical problem to be solved by the present invention is to provide a steel box bridge installation auxiliary platform which is simple in structure, easy to disassemble, can be reused, reduces labor and construction costs, improves work efficiency, and reduces safety risks of high-altitude operations.

The steel box bridge installation auxiliary platform adopted by the present invention to solve the technical problem includes a bottom support frame, a base and a movable railing. The bottom support frame is a rectangular frame, and the bottom support frame is composed of two or more vertical rectangular The tube is composed of more than two horizontal rectangular tubes vertically intersecting the longitudinal rectangular tubes, the base is arranged at the corner of the bottom support frame, and the movable railing is movably connected with the base.

Further, it also includes a platform plank, and the platform plank is arranged on the bottom support frame.

Further, the base is made of steel pipes, the movable railings are provided with uprights matching the steel pipes, and the uprights are inserted into the steel pipes.

Further, the inner diameter of the steel pipe is 2mm-3mm larger than the outer diameter of the movable railing post.

Further, the movable railing includes a U-shaped outer frame and lateral supports and longitudinal supports connected with the outer frame.

Further, the transverse rectangular tubes are arranged at equal intervals, and the intervals thereof range from 200 mm to 250 mm.

The beneficial effects of the present invention are: the steel box bridge installation auxiliary platform of the present application is placed on the steel box bridge box body, and the operator can perform lining, welding, grinding, and paint repair operations on the steel box bridge installation auxiliary platform. The movable railing can provide support for the operating workers, prevent the workers from accidentally falling during operation, and allow the workers to concentrate on construction, which can significantly improve work efficiency. The platform decking can be used for operators to work on it and stack some tools and equipment, and it can also prevent sparks from splashing to the ground when the plate unit is welded, affecting passing pedestrians and vehicles.

detailed description

The present invention will be further described below in conjunction with accompanying drawing.

As shown in Figures 1 and 2, the steel box bridge installation auxiliary platform of the present invention includes a bottom support frame, a base 3 and a movable railing 4, the bottom support frame is a rectangular frame, and the bottom support frame is composed of two or more The longitudinal rectangular tube 1 arranged in parallel is composed of more than two transverse rectangular tubes 2 vertically intersecting with the longitudinal rectangular tube 1, the base 3 is arranged at the corner of the bottom support frame, and the movable railing 4 and the base 3 are Removable connection. The horizontal rectangular tube 2 and the vertical rectangular tube 1 are assembled and welded into a whole according to the length and construction requirements of the steel box bridge according to 4-6m segments, and the base 3 is welded on the horizontal rectangular tube at the end. During use, the steel box bridge casing 9 and the box bridge casing are assembled and hoisted on the designated position, then the steel box bridge installation auxiliary platform of the application is placed on the steel box bridge casing 9, and the operator can The steel box bridge is installed on the auxiliary platform for lining, welding, grinding, and painting operations. The movable railing 4 can provide support for the operator to prevent the worker from accidentally falling during operation, allowing the worker to concentrate on construction, which can significantly improve work efficiency. The longitudinal rectangular tube 1 can be placed at a protruding position on the outer edge of the bottom plate, and the transverse rectangular tube 2 is flush with the upper surface of the longitudinal rectangular tube 1 . The width of the movable railing 4 is set according to the distance between the steel box bridge box body 9 two webs. The movable railing 4 and the base 3 are movably connected to facilitate the dismounting and installation of the movable railing 4 .

It also includes a platform plank 8 which is arranged on the bottom support frame. The platform plank 8 can be used for operators to work on it and stack some tools and tools, and can also prevent sparks from splashing to the ground when the plate unit is welded, affecting passing pedestrians and vehicles.
