Title:
SPACER FOR BAR ARRANGEMENT
Document Type and Number:
Japanese Patent JP3425554
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a spacer for bar arrangement, capable of being inexpensively manufactured, having strong force of constraint on a reinforcing bar and a simple structure, enabling the reduction of the load of checking and adjusting a concrete thickness in the case of placing concrete, and allowing the construction period for a foundation slab, etc., to be shortened.
SOLUTION: In the spacer for the bar arrangement, serving as the first invention, a projection 25 for preventing the detachment of the reinforcing bar 3 is installed above a reinforcing bar supporting part 23 whereon the reinforcing bar 3 is placed. The projection 25 is approximately horizontally formed in such a manner that both sides of the projection 25 face a vertical direction. The projection 25 is pressed for elastic deformation by the reinforcing bar 3 in the case of the placement of the reinforcing bar 3 on the supporting part 23 and put back into an original position after the placement of the reinforcing bar 3. The spacer serving as the second invention is provided with a projection 4 for detecting the thickness of the concrete 6 to be placed.
