In addition, in the above embodiment, the waterproof partition plate mechanism 4 and the shock absorbing material 5 are provided between the exterior material 2a and the lower frame 3, but the present invention is not limited to this configuration. In short, if only the waterproof partition plate mechanism 4 is installed on the outer side,
It is possible to prevent foreign matter such as rainwater from entering between the floating connection portions 1. In that case, the impact absorbing material 5 may be installed in a portion where the drop impact force accompanying the lifting of the upper frame 2 can be suitably reduced, such as being installed in place of the support member 9.

Further, in the above embodiment, the shock absorbing material 5
Has its upper end cut off from the lower surface of the upper frame 2 and its lower end fixed to the upper surface of the lower frame 3.
And the lower end may be cut off from the upper surface of the lower frame 3 without being limited to the above configuration.

Although the embodiments have been described above, the present invention is not limited to these embodiments, and the range of design modification and application variation usually performed by a person skilled in the art without departing from the technical idea thereof. It is mentioned just to be included.

The waterproofing device for a finishing material having the above-described structure is implemented by the method for waterproofing a finishing material according to claim 1 described below.

The outer portion between the outer frame 2a fixed to the column 8 of the upper frame 2 and the lower frame 3 constituting the rising connection portion 1 of the building which allows the rising due to the rocking vibration during an earthquake or the like is expanded and contracted. A flexible waterproof partition mechanism 4 is installed,
An impact absorbing material 5 for reducing a drop impact force caused by the lifting is installed in the inner part.

According to the waterproofing method and waterproofing device for the finishing material having the above construction, when the upper frame 2 is lifted by the rocking vibration during the earthquake, as shown in FIG. In response to the vertical displacement between the exterior material 2a and the lower frame 3 caused by the rising of the waterproof partition plate mechanism 4, the waterproof partition plate mechanism 4 can slide and deform in the overlapping portion 4c to follow the vertical displacement as a whole. Therefore, not only during normal times but also when floating,
Does not create any gaps in appearance. In addition, when the waterproof partition plate mechanism 4 and the shock absorbing material 5 have an integral structure, simplification at the time of construction can be achieved, which contributes to shortening of work time. Further, since the waterproof partition plate mechanism 4 is made of a finishing material, it has excellent functional beauty.

[0027]

The waterproofing method and waterproofing device for the finishing material according to the first to sixth aspects can be suitably installed between the exterior material forming the floating joint and the lower frame.

When the upper frame rises due to rocking vibration at the time of the earthquake, the waterproof partition plate mechanism as a whole is protected against vertical displacement between the exterior material and the lower frame caused by the lifting of the upper frame. Since the vertical connection can follow the vertical displacement, the floating connection portion does not cause any gap in appearance in normal times as well as in floating.
Therefore, it is possible to prevent rainwater from entering from the outside, and at the same time, it is possible to prevent foreign matter such as earth and sand from entering.

Further, the waterproof partition plate mechanism and the shock absorbing material are
In the case of an integral structure, simplification at the time of construction can be achieved, which contributes to shortening of work time. In addition, since the waterproof partition plate mechanism is made of a finishing material, it has excellent functional beauty.
