Embodiment Construction
[0023] Such as Figure 1-3 As shown, a resettable abutment anti-seismic block of the present invention consists of abutment dry wall 1, concrete wedge block 2, vertical steel bar 3, horizontal steel bar 4, polystyrene foam spacer block 5 and anti-bonding thin layer 6 composition. The concrete wedge block 2 is located on the abutment dry wall 1, an anti-bonding thin layer 6 is provided between the concrete wedge block 2 and the abutment dry wall 1, and the vertical Connected to the steel bar; the polystyrene foam spacer 5 is located at the lower part of the concrete wedge block 2 and on the anti-bonding thin layer 6; the vertical steel bar 3 passes through the anti-bonding thin layer 6 and the polystyrene foam spacer on it 5, to protect the vertical steel bar 3 from corrosion, etc., and at the same time, the vertical steel bar 3 can be deformed in any shape in the polystyrene foam spacer 6 . Horizontal reinforcing bars 4 connect vertical reinforcing bars 3 at the polystyrene ...
