JPH0468149A - Anchoring method for top of main reinforcing rod of column on highest floor - Google Patents

Abstract

PURPOSE:To facilitate water-proof works, piping works, etc. and increase workability, by jointing the top of the whole column main reinforcing rods of a column to a sheet of anchor plate to fix them in the concrete in the top of the jointing part of the columns and beams on the highest floor. CONSTITUTION:The top of the main reinforcing rods 3 of a column 1 is jointed in the anchorplate 6 arranged at the upper edge of the jointing part 7 of the columns and beams of the highest floor through bolts and nuts by insertion into the bored holes on the plate 6. In this condition, concrete is placed in the jointing part 7 to fix the upper edge of the column main reinforcing rod 3. In this way, the upper edge of the column main reinforcing rod 3 can be fixed without providing the extended part at the column head of the highest floor and hence, the workability of water-proof works and piping works of the highest floor can be improved and the arrangement of the column main reinforcing rod 3 can be facilitated.

悪い。(Invention) Problems and their characteristics) Conventionally, when fixing the top end of the top floor column (seven columns σ), the top floor column head was extended upward to ensure a predetermined anchoring length. If the column heads on the top floor were to protrude upward, it would be difficult to carry out waterproofing work on the 1st floor of room J, reinforcement work, etc.

Therefore, it is easy to perform waterproofing work on Yaju slough, reinforcement work, etc., and the anchor plate can be used as a spacer for the main reinforcement of the column.
We can expect effects such as easier reinforcement arrangement for column main reinforcements.
