Embodiment 1

[0024] The construction operation platform for prefabricated box girder of the present invention includes a platform body and two supporting units.

[0025] see now figure 1 , figure 1 It is a structural schematic diagram of the construction work platform of the embodiment of the present invention. As shown in the figure, the platform body includes a steel pipe frame 8 and a grid steel plate 7. The steel pipe frame is a rectangular steel pipe support, and the rectangular steel pipe support is provided with two parallel steel pipes as long sides. The short steel pipes are provided with diagonal braces between two adjacent short steel pipes to increase the strength of the steel pipe frame. Guardrail 5. figure 2 It is a schematic diagram of the steel pipe frame and the grid steel plate of the platform body of the embodiment of the present invention.

[0026] The two support units each include an upright bracket 2 and a ladder 3, the upright bracket is a well-shaped steel pip...

Embodiment 2

[0030] The manufacture method of the construction work platform for prefabricated box girder of the present invention:

[0031] The structure of the construction work platform for the prefabricated box girder of the present invention is mainly composed of a pulley with a locking function, a work platform, an up and down ladder passage, a support assembly and the like.

[0032] The operation platform is composed of three grid steel plates, the specifications are 3500*1000*4 one piece, 1000*1000*4 two pieces, and the specification is 48.3*3.0 round steel pipe, and the operation platform is welded and formed.

Abstract

A construction operation platform for prefabricating a box girder comprises a platform body and two supporting units, and is characterized in that the platform body comprises a steel tube frame and a grid steel plate, the steel tube frame is a rectangular steel tube support, the rectangular steel tube support is provided with two parallel steel tubes serving as long sides, each supporting unit comprises a vertical support and a ladder stand, each vertical support is a #-shaped steel tube frame, and the two ends of the platform body frame are erected on the vertical supports correspondingly to form a rigid component. The construction operation platform for prefabricating the box girder has the advantages that the platform structure is simple, the manufacturing principle is simple, practicability is high, operation of the device is easy, the installation speed is high, the construction efficiency is high, and safe and rapid passing of constructors and construction operation are facilitated.

Description

technical field [0001] The invention relates to a construction work platform, in particular to a construction work platform for prefabricated box girders. Background technique [0002] Prefabricated box girder is a mature construction technology in bridge construction, which is widely used in highway bridge construction. During the box girder prefabrication process, especially in the box girder steel bar binding operation, concrete pouring operation and maintenance after pouring, due to the high height of the general box girder, it is inconvenient for construction personnel to pass up and down during operation. [0003] Therefore there are above-mentioned inconveniences and problems in the construction work platform mode of known prefabricated box girder. Contents of the invention [0004] The object of the present invention is to propose a safe and reliable construction work platform for prefabricated box girders. [0005] For realizing the above object, technical solut...
