BACKGROUND OF THE INVENTION
The present invention relates to a method for constructing a heat insulating inner wall base.
[0002]
[Prior art]
Conventionally, when a curtain wall structure is adopted as an outer wall in a steel structure building, as described in JP-A-8-13654, a wooden frame that is rectangularly framed by a vertical beam and a horizontal beam when the inner wall is constructed. Heat insulation material is packed inside each partitioned frame of the material, and the heat insulation inner wall foundation panel formed by sticking a waterproof and moisture proof sheet on one side is separated from the outer wall and erected on the floor material to It has been proposed to form.
[0003]
This heat insulation inner wall foundation fixes the metal fitting body to the upper end of the heat insulation inner wall foundation panel, while fixing the runner along the steel beam to the flooring, inserts the lower end of the heat insulation inner wall foundation panel into the runner, It is formed by abutting against the indoor side edge of the lower flange of the steel beam, and by fixing the fixing member through the metal fitting body into the indoor side edge of the lower flange of the steel beam. As a result, the heat insulation of the indoor space is enhanced, and at the same time, a ventilation space is secured between the outer wall back surface and the heat insulating material to prevent the occurrence of internal condensation.
[0004]
[Problems to be solved by the invention]
However, when forming the above-mentioned heat insulation inner wall foundation, the standing position of the heat insulation inner wall foundation panel is the metal fitting body that abuts against the indoor side edge of the lower flange of the runner and the steel beam that are fixed to the flooring in accordance with the steel beam Therefore, in order to place the insulated inner wall foundation panel closer to the outer wall or further away from the outer wall, the size of the insulation inner wall foundation panel should be set according to the standing position of the insulated inner wall foundation panel relative to the outer wall. Different types of metal fittings are required. Therefore, as long as a single metal fitting body of the same size is used, the distance from the outer wall can be changed depending on the relationship between the room and the interior space, when the shoji is provided in the Japanese-style room, or due to the relationship with the pillar. Therefore, it is impossible to erect an insulation inner wall base panel.
[0005]
Moreover, since the heat insulation inner wall base panel is positioned on the basis of the steel beam as described above, the standing position is influenced by an error in manufacturing the steel beam. As a result, an error may occur in the standing position of the heat insulating inner wall base panel. In such a case, adjustment work of the heat insulating inner wall base panel is required.
[0006]
The present invention has been made in view of such problems, and the thermal insulation inner wall base panel is positioned with high accuracy and built in the standard position and other positions as necessary without increasing the number of parts. The construction method of the heat insulation inner wall base | substrate which can be provided is provided.
