材にかするものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an inorganic heat insulating material composed of lightweight mortar.
従来、この種の断熱材としては、板状に加工された有
機の発泡体と、現場で発泡させるものとが知られてい
る。Heretofore, as this type of heat insulating material, an organic foam processed into a plate shape and a material that is foamed on site are known.
そして、前者は、断熱の施工に当たっては、予め型枠
工事で断熱材を取り付け、コンクリート打設時に必要箇
所に打ち込まれる。In the former case, in heat insulation construction, a heat insulation material is attached in advance by formwork construction, and the heat insulation material is driven into necessary places during concrete pouring.
又、後者は、コンクリート打設後のコンクリート表面
に吹付け施工されるかコンクリート壁体と仕上材との空
隙に充填施工される。The latter is sprayed on the surface of the concrete after it has been poured, or the space between the concrete wall and the finishing material is filled.
これらの有機の発泡体としては、プラスチックフォー
ムが知られている。その一例を挙げると、次の通りであ
る。Plastic foams are known as these organic foams. An example thereof is as follows.
硬質ウレタンフォームの場合、比重が0.03、圧縮強度
1.4〜2.0Kgf/cm2、熱伝導率0.020〜0.025Kcal/m.h.℃、
又、ポリスチレンフォームの場合には、比重が0.03、圧
縮強度2.5〜3.0Kgf/cm2、熱伝導率0.025〜0.030Kcal/m.
h.℃である。In case of rigid urethane foam, specific gravity is 0.03, compressive strength
1.4-2.0Kgf / cm 2 , thermal conductivity 0.020-0.025Kcal / mh ℃,
Further, in the case of polystyrene foam, the specific gravity is 0.03, the compressive strength is 2.5 to 3.0 Kgf / cm 2 , the thermal conductivity is 0.025 to 0.030 Kcal / m.
h. C.
然し、従来の断熱材では、以下に示す如く、施工上及
び耐火上の問題がある。However, the conventional heat insulating material has problems in construction and fire resistance as described below.
即ち、施工上の問題点として、強度が弱い。型枠
取付及び打込みに費用が増加する。型枠脱型の際に断
熱材を損傷する、ことが挙げられる。That is, strength is weak as a problem in construction. Costs increase for mounting and driving formwork. The heat insulating material may be damaged when the mold is removed from the mold.
又、耐火上の問題点としては、有機の発泡体である
ため、可燃性であり、燃焼した際に有毒ガスを発生する
ものが多い。主材料が有機であるため、燃え易い、こ
とが挙げられる。Further, as a problem in fire resistance, since it is an organic foam, it is flammable and often produces a toxic gas when burned. It is easy to burn because the main material is organic.
又、無機質系の発泡断熱材の開発も試みられているが
断熱性能や強度的に問題があると共に、施工性，コスト
面で難がある。In addition, attempts have been made to develop an inorganic foamed heat insulating material, but there are problems in heat insulating performance and strength, and there are difficulties in workability and cost.
又、従来軽量化と断熱を考慮したものとして、パーラ
イトを添加したパーライトモルタルが知られている。こ
のパーライトモルタルの性質をセメント１に対してパー
ライト３の場合の容積比配合に基づいて示すと次の通り
となる。曲げ強度（４週間）29.7Kgf/cm2、圧縮強さ
（４週間）116Kgf/cm2、気乾比重1.06、熱伝導率0.18Kc
al/m.h.℃となる。Further, perlite mortar to which pearlite is added has been conventionally known in consideration of weight reduction and heat insulation. The properties of this pearlite mortar are as follows, based on the volume ratio mixture of cement 1 to pearlite 3. Bending strength (4 weeks) 29.7 Kgf / cm 2 , compressive strength (4 weeks) 116 Kgf / cm 2 , air-dry specific gravity 1.06, thermal conductivity 0.18 Kc
It becomes al / mh ℃.
然し、パーライトモルタルは、熱伝導率0.18Kcal/m.h
℃と上述したプラスチックフォームに比して大きいた
め、プラスチックフォームに比して断熱性が劣ってい
る。However, perlite mortar has a thermal conductivity of 0.18 Kcal / mh.
Since it is higher than the above-mentioned plastic foam, the heat insulation is inferior to the plastic foam.
又、パーライト自体の比重が0.5〜0.7であるため、通
常では、比重が0.8〜1.4程度のものしか使用されていな
い。そして、この軽量モルタルの比重を更に小さくしよ
うとすると、強度が低下し、施工上からも実用に供し得
なくなる虞がある。Further, since the specific gravity of perlite itself is 0.5 to 0.7, only those having a specific gravity of 0.8 to 1.4 are usually used. Further, if the specific gravity of this lightweight mortar is further reduced, the strength is lowered and there is a possibility that it cannot be put to practical use in terms of construction.
