The utility model discloses a constitution includes: the tension device comprises two girder clamps, wherein one end of the upper part of each girder clamp is provided with a hook-shaped structure, the lower surface of the hook-shaped structure is attached to the upper surface of a pressure equalizing beam, the lower surface of the pressure equalizing beam is attached to the lower edge of a girder, the other end of each girder clamp is connected with the girder through a bolt, the lower part of each girder clamp is of a frame structure, a frame of each girder clamp is provided with an inclined wall, a tension jack is attached to the inner surface of the inclined wall, a steel cable sequentially penetrates through the inclined wall and is connected with the tension jack, and the steel cable clamp is attached to the tension jack. The utility model is used for a be used for girder steel to hang and piece together construction anti-top controlling means.
Description
The technical field is as follows:
the utility model relates to a girder steel is hung and is pieced together construction and turn over a controlling means.
Background art:
the steel main beams of the large cable-stayed bridge with the box-type steel main beams on the two sides can be twisted outwards after being connected with the stay cables, and the construction quality of the bridge deck is seriously affected.
The utility model has the following contents:
the utility model aims at providing a girder steel is hung and is pieced together construction and anti-control device pushes up.
The above purpose is realized by the following technical scheme:
the utility model provides a girder steel suspended assembly construction anti-top controlling means, its constitution includes: the tension device comprises two girder clamps, wherein one end of the upper part of each girder clamp is provided with a hook-shaped structure, the lower surface of the hook-shaped structure is attached to the upper surface of a pressure equalizing beam, the lower surface of the pressure equalizing beam is attached to the lower edge of a girder, the other end of each girder clamp is connected with the girder through a bolt, the lower part of each girder clamp is of a frame structure, a frame of each girder clamp is provided with an inclined wall, a tension jack is attached to the inner surface of the inclined wall, a steel cable sequentially penetrates through the inclined wall, the tension jack is connected with the steel cable clamp, and the steel cable clamp is attached to the tension jack.
The steel beam suspension assembly construction reverse jacking control device is characterized in that a central support rod is mounted at the lower part of a steel cross beam through a bolt, the lower end of the central support rod is attached to an arc-shaped steel pipe, and a steel cable penetrates through the steel pipe and is connected with main beam clamps at two ends.
The utility model has the advantages that:
1. the utility model discloses two girder fixture have, girder fixture be connected with the box steel girder of pontic both sides respectively, connect the back through the stretch-draw jack tractive the cable wire produce to the correction force of cable bridge axis direction, and then make the girder that produces because of the suspension cable pulls twist reverse and obtain correcting, fundamentally has eliminated girder torsion deviation that can't overcome in the former construction method, has ensured construction quality.
2. The utility model discloses use two sets of jack-draws, this structure can realize that the big deviation is corrected, makes this product be applicable to the large-scale cable-stay bridge construction of the wide bridge face of big span.
3. The utility model discloses a cable wire passes the steel pipe, be the arc because of this steel pipe prefabrication, so can store up partial lubricating grease in the pipe, lubricating grease plays the lubrication action in the construction and reduces the cable wire with the steel pipe between frictional force, can guarantee central branch both ends atress symmetry even, improved the construction precision.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
example 1:
the utility model provides a with anti-controlling means that pushes up of girder steel suspended ceiling tile construction, the constitution includes: the tension device comprises two main beam fixtures 5, wherein a hook structure 10 is arranged at one end of the upper portion of each main beam fixture, the lower surface of the hook structure is attached to the upper surface of a pressure equalizing beam 6, the lower surface of the pressure equalizing beam is attached to the lower edge of a main beam 7, the other end of each main beam fixture is connected with the main beam through a bolt, the lower portion of each main beam fixture is of a frame structure, a frame of each main beam fixture is provided with an inclined wall 11, a tension jack 1 is attached to the inner surface of the inclined wall, a steel cable 2 sequentially penetrates through the inclined wall, the tension jack is connected with the steel cable fixture 12, and the steel cable fixture is attached to the tension jack.
Example 2:
according to the steel beam suspension assembly construction reverse jacking control device in the embodiment 1, the lower part of a steel beam 9 is provided with a central support rod 4 through a bolt, the lower end of the central support rod is attached to an arc-shaped steel pipe 3, part of lubricating grease can be stored in the arc-shaped steel pipe, and a steel cable penetrates through the steel pipe and is connected with the main beam clamps at two ends.
