JOINT SEALANT, SLIT STRUCTURE OF CONCRETE STRUCTURE, METHOD TO FORM SLIT IN CONCRETE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a joint sealant and others for a concrete structure that may be manufactured readily and do not impair fireproofing, dust-resisting and soundproofing properties.SOLUTION: A joint sealant is filled in an aseismic slit formed in a concrete structure comprising a wall body (a), a floor part (c) and a column part (d), and includes a horizontal joint filler 30 filled in a horizontal slit 10 formed between the wall body (a) and the floor part (c), and a vertical joint filler 40 filled in a vertical slit 20 formed between the wall body (a) and the column part (d). The horizontal joint filler 30 is made of a single elastic material, and the vertical joint filler 40 is made of a single material. The joint sealant is provided that is formed of a material that is deformed when exposed to an earthquake at a same speed with the horizontal joint filler 30, or of materials that are deformed when exposed to an earthquake at a same speed, along with a slit structure and a slit forming method that uses the joint sealant.SELECTED DRAWING: Figure 1
