Abstract
The utility model discloses a manhole is advanced to steel box girder bridge, include the steel box girder that is formed by web, roof and the welding of a plurality of U-shaped stiffening rib, wherein, web and roof weld each other, and the equidistant welding of U-shaped stiffening rib has seted up a manhole between the double-phase adjacent U-shaped stiffening rib on the roof in the bottom surface of roof. The utility model discloses when piecemeal part roof unloading, confirm suitable trompil position as required, guarantee to advance the manhole and open the system quality, the site operation of being convenient for shortens construction cycle.
Description
Technical Field
The utility model relates to a steel box girder technical field, more specifically say, especially relate to a manhole is advanced to steel box girder bridge.
Background
The steel box girder is also called steel plate box girder, and is a common structural form of a large-span bridge. When the large-scale steel box girder is manufactured and installed, the steel box girder needs to be divided into proper lengths due to large volume and heavy weight, each segmented structure is fixedly connected in an assembling mode during field installation, constructors need to enter the internal construction operation of the steel box structure, temporary manholes are formed in the field, and the quality of the temporary manholes formed is difficult to guarantee due to uncertain factors such as hole opening equipment and hole opening positions.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the not enough of above-mentioned prior art, provide a manhole is gone into to steel box girder bridge, shorten on-the-spot installation construction cycle, guarantee installation quality.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a manhole is gone into to steel box girder bridge, includes the steel box girder that is formed by web, roof and the welding of a plurality of U-shaped stiffening rib, and wherein, web and roof are welded each other, and the equidistant welding of U-shaped stiffening rib is in the bottom surface of roof, has seted up one manhole on the roof between the two-phase adjacent U-shaped stiffening rib.
The utility model discloses when piecemeal part roof unloading, confirm suitable trompil position as required, guarantee to advance the manhole and open the system quality, the site operation of being convenient for shortens construction cycle.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-a web; 2-a top plate; 3-U-shaped stiffeners; 4-manhole.
Detailed Description
The present invention will be described in further detail with reference to the following examples, which are not intended to limit the invention.
As shown in fig. 1, the utility model provides a manhole is advanced to steel box girder bridge, include the steel box girder that is formed by web 1, roof 2 and the welding of a plurality of U-shaped stiffening rib 3, wherein, web 1 welds each other with roof 2, and the equidistant welding of U-shaped stiffening rib 3 has seted up one manhole 4 in the bottom surface of roof 2 between the two-phase adjacent U-shaped stiffening rib 3 on roof 2.
The utility model discloses when 2 unloading of piecemeal part roof, confirm suitable trompil positions as required, guarantee to advance manhole 4 and open the system quality, the site operation of being convenient for shortens construction cycle.
Claims (1)
