Description

A kind of steel box-girder segmental hoisting turning clamping fixture

Technical field

The utility model relates to steel structure bridge field, specifically a kind of steel box-girder segmental hoisting turning clamping fixture.

Background technique

With the development of assembling type steel structure at home, steel construction overbridge because its is easy to make, fast increasingly by Industry favor.Steel structure bridge is divided into several monomers, Mei Gedan according to transport capacity and production factory's crane capacity etc. There is presently no more mature techniques for the lifting overturning of body, and matching between department's Suo work and craneman synthesizes control monomer and hang The principal element of dress overturning deformation, controllability be not high.

Utility model content

The purpose of the utility model is to provide a kind of lifting turning clamping fixtures of steel box-girder segmentation monomer, and the processing is simple, stress Performance is good, can effectively prevent deforming when the lifting overturning of steel structure bridge monomer, and pass through pin shaft and steel structure bridge point The advantages that block monomer has good fixation, easy for installation, detachable recycling.

To achieve the goals above, the technical solution adopted in the utility model is:

A kind of steel box-girder segmental hoisting turning clamping fixture, mainly by arc flange plate, radial stiffener, circumferential stiffener, bow Shape web, connection otic placode composition；

Radial stiffener is welded in arc flange plate；Radial stiffener and circumferential stiffener weld；

Circumferential stiffener and arch web weld；

Connection otic placode is welded on arch web.

Inserted with connection pin shaft in the circular hole of connection otic placode.

The advantages of the utility model, feature was:

1, arch web and arc flange plate is arranged in the steel box-girder segmental hoisting turning clamping fixture that the utility model uses, one end It is welded into rigid load end, the other end is 2 pieces of connection otic placode.Arch web two sides have respectively radially and circumferentially stiffener to increase The intensity, rigidity of this structure.Connection otic placode is segmented exposed partition with steel structure bridge and is connect using pin shaft, and pin shaft is using customization shape Shape prevents from slipping, and surface is strengthened by Carburization Treatment, prevents this mould from overturning stress deformation.

2, the lifting lug of the utility model and main body mould are using welding, securely and reliably, at steel structure bridge connection otic placode every Plate uses the Circular Plate reinforcement of partition uniform thickness at cotter way hole position, and mould otic placode uses unsymmetric structure, guarantees mould and steel knot The bonding strength of structure bridge segmentation.

3, the mould end of the utility model bears steel structure bridge using arc-shaped flange plate and is segmented gravity, round and smooth mistake It crosses, uniform force, avoids steel structure bridge segmentation bottom plate top plate living in lifting switching process that stress is concentrated to cause to deform.

4, the mould abdomen of the utility model is that mould is able to bear steel structure bridge using radially and circumferentially stiffener Gravity will not deform, unstability.

5, the otic placode of the utility model is connect with steel structure bridge partition using pin shaft, can repeatedly be dismantled, convenient for group load It connects.

Specific embodiment

Below with reference to say attached drawing 1-5 and appended drawing reference to the utility model be further described.

A kind of steel box-girder segmental hoisting turning clamping fixture, by arc flange plate 2, radial stiffener 1, circumferential stiffener 3, arch Web 4, connection otic placode 5 form；Uniform thickness transition portion does not use arc transition to connection otic placode 5, and four peripheral end portion use 2mm transition circle Angle transition；Pin shaft 6 is connected by mechanical processing and positioning pin hole and transition shoulder, surface carries out Carburization Treatment, increases pin shaft hardness. Arch web 4 is welded with arc flange plate 2, and radial stiffener 1, circumferential stiffener 3 and connection otic placode 5 are welded to arch abdomen On plate.

Arc flange plate 2 is stressed directly structure when being overturning, by circumferential stiffener 3 and radial stiffener 1 by steel box-girder Segment gravity is distributed on arc flange plate 2.

The connection otic placode 5 of the utility model mould shares 2 groups, and every group of connection otic placode is different by a common ellipsoid and one Property step type otic placode composition, be suitable for the different block board thickness of steel box girder segment.

Embodiment

When lifting, according to different block board thicknesses, it is welded with the reinforcing ring of respective thickness in steel box-girder partition connection hole, is lifted Connection pin shaft is penetrated in prefabricated connecting hole when overturning, carries out steel box girder segment lifting, entire hoisting process after positioning pin is fixed The middle arc-shaped flange plate in mould end bears steel structure bridge and is segmented gravity, rounding off, and uniform force avoids lifting from being turned over Steel structure bridge segmentation bottom plate top plate living concentrates stress to cause to deform in journey, and mould abdomen is using radially and circumferentially stiffener The gravity that mould is able to bear steel structure bridge will not deform, unstability.
