However, in such a furring strip mounting method, it is necessary to construct a rising portion before the lateral furring strip is supported by a pair of pillars, so that the construction period is likely to be delayed.

In view of this situation, a main object of the present invention is to provide a furring strip mounting method in which the construction period is unlikely to be delayed.

The first characteristic configuration of the present invention is a furring strip mounting method for fixing a lateral furring strip to the upper surface of a rising portion rising from a floor slab.
A front-end adjustment step of adjusting and supporting the horizontal furring strip to a pair of adjacent columns in an appropriate posture, and a horizontal furring strip fixing step of fixing the horizontal furring strip to the upper surface of the rising portion after the advance adjustment step. , And in the advance adjustment step, the horizontal furring strip is supported by the pair of pillars in a state where the fixing tool fixed to the horizontal furring strip is projected into the construction space in which the rising portion is constructed. In the horizontal furring strip fixing step, concrete is placed in the construction space so as to bury the fixing tool to construct the rising portion, so that the horizontal furring strip is fixed to the rising portion in the proper posture. At the point.

According to this configuration, in the advance adjustment step, the horizontal furring strip is supported by a pair of pillars in an appropriate posture, and the fixing tool fixed to the horizontal furring strip is projected into the construction space. By executing the horizontal furring strip fixing process in such a state and placing concrete in the construction space, a rising portion is constructed and a fixing tool is embedded in the constructed rising portion, so that the horizontal trunk is in an appropriate posture. The edge can be fixed on the upper surface of the rising portion.
Then, by executing the pre-adjustment process before the horizontal furring strip fixing process in this way, the horizontal furring strip is placed in a pair of pillars in an appropriate posture before the concrete is placed in the construction space to construct the rising portion. Since it can be supported, the work of attaching the vertical furring strip or another horizontal furring strip to the upper side of the horizontal furring strip can be performed, and the construction period is less likely to be delayed.

In the second characteristic configuration of the present invention, the direction orthogonal to the direction in which the horizontal furring strip extends in a plan view is set as the adjusting direction, and the pillar is formed at the first joining portion for joining the horizontal furring strip and the pillar. A long hole is provided in the adjusting direction for bolting the lateral furring strip so as to be adjustable in the adjusting direction, and the second joining portion for joining the lateral furring strip and the fixing tool is provided. A round hole is provided for bolting the fixing tool to the lateral furring strip so as not to be adjustable in the adjusting direction.

According to this configuration, by joining the horizontal furring strip to each of the pair of pillars using a long hole, the position of the horizontal furring strip with respect to each of the pair of pillars can be adjusted. It can be supported by a pair of pillars with the edges adjusted to the proper posture. Further, by joining the horizontal furring strip and the fixing tool using a round hole, the fixing tool can be bolted to the horizontal furring strip with high joining strength.

The third characteristic configuration of the present invention is that the portion of the rising portion on the indoor side has a protruding step portion that protrudes upward from the bottom surface of the horizontal furring strip.

According to this configuration, the protruding step portion of the rising portion can function as a water return, and it is possible to prevent water such as rainwater from entering the room side from the rising portion.

The fourth characteristic configuration of the present invention is that a plurality of vertical furring strips are grounded on the horizontal furring strip so as to extend upward from the horizontal furring strip to form a lowermost furring strip unit. ..

According to this configuration, the horizontal furring strip and a plurality of vertical furring strips can be unitized into the lowermost furring strip unit by the groundwork, so that the man-hours for building the steel frame can be reduced.
