Flexible corner cover of transverse leveling gap in joint between bridge slabs and installing construction method of joint sealer using the same

摘要

The present invention can quickly reinforce the corner cracks or cracks of the corners of the concrete slabs facing each other, and at the same time, the transverse level difference slab that can easily reinforce the corners of the concrete slab with an uneven level difference on the crossing of the opposite slabs. Corner level stiffeners and sealing materials installation method for bridge expansion joints using the same. According to a preferred embodiment of the present invention, in the corner level steel slab for crossing level difference slab for protecting the corner portions of the bridge-side concrete slab and the alternating-side concrete slab from the impact of the vehicle driving the bridge, A steel angle bar having an angled cross section so as to extend over a predetermined length; A plurality of reinforcement bands connected to each other at both long sides of the steel bar; The reinforcing bar is connected to each of the plurality of reinforcing bars integrally and positioned at a predetermined distance from the steel bar angle; includes, the area having the reinforcing bars is formed through the adhesive layer through hole in the thickness direction, bridge-side concrete slab Alternatively, the longitudinal angle bar leveling cutting grooves which are partially cut with a predetermined gap and depth are formed on both long sides of the steel angle bar so as to accommodate the level difference generated in the width direction on the alternate concrete slab. do.
