Description

The present invention relates to a handrail device including two struts that are erected at predetermined intervals.

In some cases, it may be necessary to construct a handrail device (guard fence) by erecting columns on each of the two floors that may be relatively displaced. For example, in a building having a seismic isolation device, a handrail device is constructed between a portion supported by the seismic isolation device and a portion not supported by the seismic isolation device. As the handrail device used in such a place, those having various structures have been proposed (see, for example, Patent Document 1).

FIG. 5 is a front view showing an example of the conventional structure of the handrail device. In the drawings, reference numerals 101 and 102 indicate wall portions that function as columns, and reference numeral F1 indicates that one wall portion 101 is erected. The reference numeral F2 indicates a floor portion in which the other wall portion 102 is erected. Reference numeral 103A indicates a fence portion supported by one wall portion 101, and reference numeral 103B indicates a fence portion supported by the other wall portion 102. The fence portion 103A is not fixed to the fence portion 103B, and the fence portion 103A and the fence portion 103B are configured so as to be relatively movable in the ± x direction. Therefore, even if the floor portions F1 and F2 move relative to each other in the ± x direction due to an earthquake or the like, the fence portions 103A and 103B move freely in the respective directions, and the fence portions 103A and 103B do not break. It has the feature.
