石材ベニヤの特徴

Would seem a pretty simple question right? And yes, it’s a pretty simple answer – cladding made from stone.  However from the meetings I have with contractors and surveyors, I see it often gets over-complicated in designers’ minds and confused with traditional stone masonry.

Natural stone is one of the oldest materials used by man in construction.  We only have to look at buildings such as the Taj Mahal completed in 1648 using white marble, or the Great Pyramid thought to have been completed in 2560BC made predominantly out of limestone to appreciate the longevity of stone as a material.  (Imagine the architect specifying the Design Life for the Pyramid….)

タージ・マハルが建てられて以来、建築方法は明らかに変化しており、建設業界内のさまざまな部門や業界が長年にわたり相互参照し、ネットワークを構築してきたおかげで、堅固な石造りの建物の外観を作り出すために重い石のブロックを積み重ねる必要はなくなりました。 

Traditional stone masonry (not something we do here at AlterEgo by the way), is loaded onto the building’s foundations and uses stones and mortar, tied back with wall-ties – think brickwork.

一方、現代の石造りの外装は建物の構造から吊り下げられ、金属製のレインスクリーンシステムとほぼ同じ方法で組み立てられます。 

ご存知の通り、石張りは レインスクリーンクラッディング システムであり、そのように扱われるべきです。 

Looking through a cross section of a typical stone cladding build-up you’ll see lots of familiar components: spreader bars, helping-hand brackets, rails and T-bars.  It’s only the facing material which is interchangeable. 

There are a few nuances when working with natural stone for the first time, but nothing that a day’s training and our on-site support won’t cover.

So if you’re a contractor used to installing aluminium and steel cladding or you specialize in terracotta; don’t be afraid of stone! Check out this video showing the simplicity of our EGO-02S system EGO 02s INSTALLATION BETA – YouTube

石のクラッディングパネルを支持構造に固定する場合、主に 2 つの固定方法があります。

アンダーカットアンカー

With an undercut anchor system, typically used for larger format panels, holes are pre-drilled into the back of the stone, a sleeve and bolt inserted and fixed onto a hanging clasp and horizontal system.  This method is good for natural stone panels with a thickness range from 30-50mm and can be used in both stack and stretcher bond layouts, typically in a portrait layout.   Undercut anchors are always used in soffit situations.

固定具はすべてパネルの裏側にあるため、この方法は完全に秘密固定であり、固定具は見えません。

彫る

The kerf method of fixing stone is where a continuous groove is cut in the top and bottom of the stone, and the stone simply sits on a rail or clasp at the bottom and restrained at the top.  A kerf system works particularly well for horizontally laid panels in either stack or stretcher bond.

設置のスピードとシンプルさ、そしてパネルを非連続的に設置できるという事実により、この方法は最も広く使用されている石材外装システムとなっています。

どちらの設置方法も通常はオープンジョイントですが、非移行性シーラントを使用したポインティングジョイントにより、伝統的な石造建築のような外観を実現できます。
