CABLE TRENCH BETWEEN BUILDINGS AND ITS CONSTRUCTION METHOD AND BLOCK STRUCTURE USED FOR THE CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To shorten the construction term of a plant having a cable trench between buildings by forwarding the initiation time of cable laying work in the cable trench between buildings. SOLUTION: Supports 4a and 4b and each of beams 1a and 1b are left in a set space 24 of a cable trench between buildings even after forming the upper concrete slab 6a, and by using the supports 4a and 4b as support means for the cable tray 5, the cable tray 5 is placed in the set space 14. Without waiting for the increase of the design strength of the upper concrete slab 6a, the cable is laid in the trench between building in this construction method.
