Middle fishback is between two side fishbacks, to be flexibly connected between middle fishback and two side fishbacks, two side fishbacks
It is fixed with anchor rib separately below, pre-buried angle steel, anchor rib side upper end fixed displacement case, middle fishback are fixed on the outside of anchor rib
Both ends be bolted on adjacent crossbeam, a crossbeam by two pieces fishback splicing is fixed together, crossbeam
Both ends are stretched into displacement case, and the both ends of crossbeam are cased with high strong spring, and one end of high strong spring is fixed on displacement box body, another
End is stopped by the gear block set on crossbeam, while gear block limitation crossbeam removes displacement case.
A kind of above-mentioned double broach multi-directional deflections expansion joint, the roof movement of displacement case are connected on babinet, and when repair can
To remove；In the intersection of middle fishback and side fishback, there are stainless steel plate, stainless steel plate to be fixed under the fishback of side below
Face when middle fishback is subjected to displacement, reduces frictional force, and roof movement connection can be hinge connection or snap connection.
The upper and lower surfaces at a kind of above-mentioned double broach multi-directional deflections expansion joint, crossbeam are equipped with stainless steel plate, crossbeam hair
When raw displacement, reduce frictional force.
A kind of above-mentioned double broach multi-directional deflections expansion joint, waterstop are buckle-type waterstop, and the bending at both ends can block
On the outside of the anchor rib on fixed pre-buried angle steel.
Using a kind of double broach multi-directional deflections expansion joint of the structure, effectively lateral, longitudinal, the upper and lower deflecting of beam body is being solved
Change in location, middle fishback, crossbeam, waterstop damage after, easily replaced；Broach in cross beam support in displacement case
Plate, fishback moves in the horizontal plane in guarantee, when crossbeam is subjected to displacement, fishback activity in capable of also driving；The top of displacement case
Plate is movably connected on babinet, and when repair can open displacement case, facilitate the replacement of crossbeam；During gear block on crossbeam can prevent
Fishback unilateral side be subjected to displacement it is excessive, while limit crossbeam remove displacement case；The high strong spring on both sides cooperates, and balances both sides
Size when being subjected to displacement, buckle-type waterstop facilitate the replacement of waterstop, a crossbeam to connect two middle fishbacks simultaneously, make
All middle plates are linked together in the same direction, the same amount of fishback displacement in guarantee.
Description of the drawings
