FIG. 12 is a side view showing the spring 15 provided between the lowermost stage of the louver and the building structure. In FIG. 12, instead of the lower support structure of FIG. 11, a spring 15 is connected between a steel beam constituting the building structure C and the lowermost short rod member 4 by a female threaded coupler 6. The connection by the coupler 6 with the female thread is the same as in the case of FIG. A compression coil spring 15a is provided inside the spring 15, and a tension is applied to the short rod member 4 by the compression coil spring 15a. The spring 15 can be provided on the upper part of the louver assembly L.

By providing the spring 15, as a countermeasure against the tension relaxation due to the thermal expansion of the rod member 4 particularly in summer, the compressive force due to the thermal expansion is over-tensioned further than the necessary set tension at the time of introducing the tension. It is possible to keep a constant tension state, depending on the influence on the boundary conditions.

As the spring 15, a leaf spring, a flat spring, or the like can be used instead of the compression coil spring 15a, or an air spring can be used.

The louver support structure having the above structure can be supported in advance on a curtain wall provided with a decorative board made of a water-resistant material, and the construction efficiency at the construction site can be improved.

In general, since the short rod member 4 has a small second moment of area, it is analyzed and designed assuming that it is a wire elastic member which resists only tensile force in principle. A minute local bending moment is generated depending on the state of rotation restriction. However, according to the louver support structure having the above-described configuration, the connection portion of the short rod member 4 and the attachment portions such as the connection support fittings 8 and the arms 9 are provided with play, gaps, and play to cope with the minute louvers. Can be prevented, and because of the displacement shape of the interlayer deformation in high-rise buildings, the ideal pin connection can be achieved in places where the generation of local bending moments cannot be avoided by the above-mentioned method. Near performance can be achieved and an extremely high quality louver support structure can be provided.

Further, by making the connection positions of the section steel 3, the short rod member 4, the connecting support 8 and the like adjustable, the construction is facilitated and the construction period is shortened.

In this case, an elastic adhesive is applied to the through hole 2 of the slat 1 over the entire area in the longitudinal direction, so that the slat 1 can be prevented from dropping in the event that the slat breaks. Alternatively, as shown in FIG. 16, the receiving metal fitting 3a can be connected by a steel bar 3b inserted into the through hole 2 of the blade 1, so that if the blade 1 is broken, the steel bar 3b can be used. It can be supported to prevent falling, and a bar steel such as a round steel is economical because the cost is lower than a shape steel such as a channel steel. Various connection means, such as welding and bolt connection, can be adopted for the connection between the steel bar 3b and the receiving fitting 3a. The receiving fitting 3a may use an angle material or an FB pressed product, and may have a bolt hole formed therein.
