... Prestressed Concrete Beam Having Holes for Arrangement of Bar and Construction Method Cross-beam of Bridge for using it

摘要

The present invention is blood. S. seeds, the main beam and the blood which is installed by throttling the direction of the bridge. S. seeds, more particularly, blood will be produced in ready-made material on how the construction of the cross beam is connected installed at regular intervals in the main beam . S. seed. by using left to form a reinforcement for a hole penetrating in the T axis direction perpendicular to the location where the cross beam is connected in the main beam is useful when cross beam installation, for good workability reduce speed and construction cost of the construction period At the same time, as one that structural stability is enhanced by the integration of the structure, blood, S. seeds at the same time providing a main beam for cross beam reinforced connecting through-hole and concrete fixing for key groove is formed, the blood S. Mr. the main beam ... P S's installation phase of the main beam, which through the use hayeoseo arranged parallel to the upper portion of the pier or abutment and; ... The blood S. seeds for cross beam reinforcement assembling while communication for inserting the main bars to the cross beam through holes of the main beam and a reinforcement phase; ... The blood S. seed grouting step of the through hole strayed into the through hole filled with a grout material of the main beam and methoxy; By pouring concrete on the outside of the cross beam reinforced assembly formed by the reinforcement phase of the cross beam for the reinforcement of blood S Mr concrete forming step of the cross beam connecting the main beams in a grid;... It provides a construction method for a cross beam of the bridge formed through.
