Two shaped steel are connected, form it into spill cavity, extrusome is arranged in the concave shaped cavity body.
Wherein, the middle side part of shaped steel two of described two " L " shapes connects the first anchor with coupling nut by bolt-nut respectively
Gu reinforcing bar；The side bottom of shaped steel two of " L " shape connects the second anchor bar respectively, wherein, first anchor bar passes through support
The anchor bar of bar connecting second, and fixed by crossing reinforcing bar.
Wherein, the second anchor bar bottom sets the shaped steel of " J " shape.
The bridge extension joint can also set gear tiny fragments of stone, coal, etc. cover plate, and it is covered on the spill cavity, the gear Zha Gai
Plate is fixed by positioning steel tube and the first anchor bar and the second anchor bar.Bridge extension joint with gear tiny fragments of stone, coal, etc. cover plate is applicable
In there is tiny fragments of stone, coal, etc. railroad bridge.Expansion gap device without tiny fragments of stone, coal, etc. railroad bridge is then without setting gear tiny fragments of stone, coal, etc. cover plate.
Further, the extrusome is macromolecular elastomer, can be selected from polyurethane elastomer, silicone elastomer or
It is a kind of in person's hydro-expansive rubber material.
Alternatively, the spacer bar is multiple.
Alternatively, the shaped steel of described " J " shape is multiple.
Bridge extension joint provided by the utility model is in concrete bridge beam-ends fixed steel, the cast height between shaped steel gap
Molecular flexibility body, forms shaped steel-macromolecular elastomer composite construction after solidification, macromolecular elastomer and shaped steel welded reinforcement 21 and
First anchor bar 4 stretches out threaded connection, difficult for drop-off.Bridge extension joint of the present utility model and beam-ends concrete binding are good
Good, high polymer elastic physical efficiency adapts to the deformation of beams of concrete completely；Even if elastomer unsticking, shaped steel also effectively can prevent beam-ends from connecing
Touch water.And the shaped steel excellent durability of multi-component alloy co-cementation, it is convenient that field maintenance is changed, and can be widely applied to railway, highway etc.
Installed etc. various concrete bridge beam-ends expansion joints.
