[Effects of the Invention] As described above, according to the fire-resistant wall joint structure according to the present invention, the joint material significantly improves the waterproofness and airtightness at the joint portion. The head of the fixture is not exposed at the joint. The fire resistance (prevention of flame penetration, etc.) is greatly improved due to the interposition of the E-shaped fixture and the roof plate. Since the deformation at the time of fixing the panel is covered by the joint cover, no skill is required for construction. Since the joint cover attachment is short, the joint cover is easily attached and does not come off. Since the front surface material and the back surface material do not come into contact with each other even at joints (connection portions), heat insulation, fire resistance (prevention of invasion of flame to the skeleton side), and dew condensation resistance are improved. It is possible to form a wall with improved heat insulation, soundproofing, external force resistance, earthquake resistance, aesthetics, and the like. There are features and effects such as.
