BACKGROUND OF THE INVENTION
The present invention relates to an architectural hermetic structure that exhibits vibration proofing and sound proofing over a long period of time.
[0002]
[Prior art]
As a conventional building structure, there is one shown in Japanese Patent No. 2733570 invented by the present inventor. In other words, a rubber body is interposed between the upper end of the first-floor column and the first-floor beam, and the tenon of the upper-end portion of the first-floor column and the mortise of the first-floor beam are fitted to each other, thereby preventing vibration. And the soundproofing is improved.
[0003]
Moreover, there exist some which are shown in FIGS. 6-8 as a conventional architectural airtight structure. That is, the horizontal member 3 is placed on the panel frame 1 with the airtight packing material 2 interposed therebetween, and the airtight packing material 2 provides airtightness and vibration and soundproofing properties.
[0004]
[Problems to be solved by the invention]
However, in the conventional technology, since the weight of the first-floor beam and the second-floor portion is placed on the rubber body or the hermetic packing material, the rubber body or the hermetic packing material is subjected to a load exceeding the allowable limit over a long period of time. There has been a problem that the restoring force or elasticity of the hermetic packing material is lost, and there is a risk of losing the effects of vibration and sound insulation.
[0005]
The present invention has been made by paying attention to such a conventional problem, and an object thereof is to provide an architectural hermetic structure capable of exhibiting vibration isolation and sound insulation over a long period of time.
