Description

  The present invention relates to a reinforcing structure for a reinforced concrete structure having a structure as a paragraph.

In conventional concrete structure design, the structure was adopted as a paragraph.
Paragraph structure means that stress concentrates at the junction between a vertical structure such as a column part or wall part of a reinforced concrete structure and a lower structure of a reinforced concrete structure, and there is a middle part in the height direction of the vertical structure. It is a structure based on the conventional reinforced concrete structure design method based on the idea that stress is less likely to concentrate than the above-mentioned joint, and the amount of main reinforcing bars in the reinforced concrete structure is the same between the vertical structure and the substructure. It is comprised so that it may differ from the lower structure containing a junction part to the predetermined height position of a vertical structure, and the part in a position higher than the said predetermined height position.
In other words, a reinforced concrete structure having a structure as a paragraph was arranged from the lower structure including the joint portion between the vertical structure of the reinforced concrete structure and the lower structure to a predetermined height position of the vertical structure. It refers to a reinforced concrete structure having a structure in which the amount of main reinforcing bars arranged in a portion higher than the predetermined height is less than the amount of main reinforcing bars. The predetermined height position is called a cut-off position (paragraph position), and the cut-off position is determined by structural calculation for each reinforced concrete structure.
Here, the part from the lower structure where the amount of main reinforcing bars has not been reduced to the predetermined cut-off position of the vertical structure is referred to as a “part that is not a paragraph”, and the “part that is not a paragraph” The upper part of the vertical structure located at a position higher than the cut-off position where the amount of main reinforcing bars is reduced compared to the part up to the cut-off position of a certain vertical structure is referred to as a “part made into a paragraph”.
In such a reinforced concrete structure having a structure as a paragraph, the damage caused by the seismic force is caused such that the part designated as a paragraph is crushed or broken.
Therefore, it is necessary to reinforce a reinforced concrete structure having a structure as a paragraph.
In the reinforced concrete structure having the structure as the paragraph, the outer periphery forming the outer surface of the reinforced concrete structure is rolled up with a steel plate (see Patent Document 1 etc.), or the outer periphery forming the outer surface of the reinforced concrete structure is cylindrical. A reinforcement structure that is reinforced by covering with a steel plate (see Patent Document 2 etc.) is known.
