The structure ensures the construction safety, avoids the damage to the coating quality of the steel beam rod piece and can be repeatedly used.
Description
Technical Field
The utility model relates to a formula of encorbelmenting operation platform especially relates to a formula of encorbelmenting operation platform for girder steel installation.
Background
The installation of the girder steel of the bridge belongs to the high-altitude operation, and an operation platform is required to be arranged for construction. Because the installation of the steel beam belongs to the high-altitude operation, the conventional floor type scaffold which is erected cannot be used as an operation platform, and when the steel beam is installed on site, the steel beam rod piece coating system is constructed, and the steel beam rod piece is welded with the section steel to arrange the operation platform, so that the surface coating quality is damaged.
Disclosure of Invention
An object of the utility model is to overcome prior art's shortcoming, provide one kind and guaranteed construction safety, avoided the destruction to girder steel member application quality to can used repeatedly be used for girder steel installation's overhanging type operation platform.
The utility model discloses a formula of encorbelmenting operation platform for girder steel installation, two spandrels that set up along the horizontal direction around including, the left end roof of two spandrels links to each other with the vertical steel sheet of a L shape steel sheet is fixed, the horizontal steel sheet of L shape steel sheet and the lower flange board of girder steel member are inserted to the space between the left end top wall of two spandrels, be fixed with the nut that an axis set up along vertical direction on the outer wall of the horizontal steel sheet of two L shape steel sheets respectively, a bolt twists the nut and the lower flange board top surface of the tight girder steel member in bolt end top the top surface of two spandrels between full spread have a plurality of steel springboards the right-hand member of two spandrels respectively the welding have a guardrail stand that sets up along vertical direction, have many horizontal poles along the interval welding about the horizontal direction between two guardrail stands.
The utility model discloses construction safety has been guaranteed to the structure, has avoided the destruction to girder steel member application quality to can used repeatedly.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model relates to an overhanging type operating platform for steel beam installation, which is shown in the attached drawing and comprises a front bearing beam 2 and a rear bearing beam 2 which are arranged along the horizontal direction, the left end top walls of the two bearing beams 2 are fixedly connected with a vertical steel plate of an L-shaped steel plate 3, the space between the horizontal steel plate of the L-shaped steel plate 3 and the top walls of the left ends of the two bearing beams 2 is inserted into the lower flange plate of the steel beam rod member 1, the outer walls of the horizontal steel plates of the two L-shaped steel plates 3 are respectively fixed with a nut 4 with the axis arranged along the vertical direction, a bolt 5 is screwed into the nut 4 and the end of the bolt tightly props against the top surface of the lower flange plate of the steel beam rod member 1, the top surfaces of the two bearing beams 2 are fully paved with a plurality of steel gangplank 8, the right ends of the two bearing beams 2 are respectively welded with a guardrail upright 6 arranged along the vertical direction, and a plurality of cross rods 7 are welded between the two guardrail uprights 6 along the horizontal direction at intervals.
Girder steel member 1 in the picture has been accomplished, when needing to adopt welding and bolt to be connected between girder steel member 1 and other girder steel member sides, can with the utility model discloses a formula of encorbelmenting operation platform lays on the girder steel member, and constructor stands and carries out the welding and the bolted connection operation between girder steel member 1 and other girder steel member sides on steel springboard 8.
If a section steel welding operation platform is directly adopted on the steel beam rod member 1, the coating quality of the steel beam rod member 1 can be damaged due to welding. This overhanging type operation platform passes through the bolt-up and fixes the application quality that can not produce the damage to girder steel member 1.
To sum up, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is familiar with the technical field of the present invention in the technical scope disclosed by the present invention, according to the technical solution of the present invention and the utility model thereof, the concept of the present invention is equivalent to replace or change, and all should be covered within the protection scope of the present invention.
