Structural concrete - arrangement of bar structure null

摘要

PURPOSE:To correct the warpage of rebar arrangement with simple structure and increase its strength against bending and shearing force by a structure wherein both mesh rebars, which are fixed to both sides of main rebars containing at least one pair of frame members arranged oppositely by the predetermined distance apart from each other, and a plurality of connecting members, each of which is spanned between a pair of the frame members consisting of the main rebars are equipped. CONSTITUTION:Between frame members 1A and 1B consisting of main rebars 3, Three connecting members 11, 12 and 13 are spanned at the predetermined intervals. Each of respective connecting members 11, 12 and 13 consists of a pair of bar members 21 and 22 and a turnbuckle 23, which connects between a pair of the bar members 21 and 22. Under the condition that rebar arrangement 6 is formed by welding mesh rebars 4 and 5 on both sides of the main rebars 3, which are formed by welding both ends of frame members 2A and 2B to the frame members 1A and 1B, the warpage of the rebar arrangement can be corrected by controlling the turnbuckles 23 so as to shorten the lengths of the three connecting members 11, 12 and 13.
