Specific embodiment

To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is described in further detail.

Referring to Fig. 1-4, a kind of track girder underground section pedestal installation clamping fixture, comprising:

Steel plate；

Bracket is connect with the top of steel plate；

Crossbeam, setting is in the bracket near portion；

Supporting beam is connect with crossbeam；

Pedestal bottom plate is connect with supporting beam；

The lower end of pedestal extends to the lower part of bracket；The under-filled of bracket has concrete.

Bracket is square frame-shaped, and bracket is respectively provided with a supporting beam at two side positions, and the supporting beam of two sides supports respectively The both ends of pedestal bottom plate.

Leveling bolt is additionally provided in supporting beam, leveling bolt is threadedly engaged with supporting beam, the end of leveling bolt and pedestal Contacts baseplate.

Supporting beam vertical crossbeams；Support and beam welding.

Steel plate bottom is equipped with dowel.

Two groups of pedestals are equipped in one bracket.

Steel plate and dowel weld.

The pre-buried 2cm thick steel plate of blinding layer and diameter 16mm dowel, pre-embedded steel slab top and channel steel bracket weld solid Fixed, channel steel bracket is chan frame according to base plate dimensioned, and chan frame can pass through reinforcement welding fixed pedestal.

The installation method of the track girder underground section pedestal installation clamping fixture, includes the following steps:

1) blinding layer pre-embedded steel slab and dowel, pre-embedded steel slab top and bracket weld；2) by beam welding on bracket； 3) supporting beam is welded on crossbeam；4) bracket is welded on the reinforcing bar of track girder；

5) support and pedestal bottom plate are welded；6) pedestal bottom plate is mounted in supporting beam by leveling bolt, passes through tune Flat bolt adjusts pedestal bottom plate；7) after pedestal bottom plate is adjusted, by support and beam welding；8) casting concrete.
