Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ゴミ焼却炉構築等に用いる耐熱性に富んだブ
ロックに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a block having a high heat resistance used for constructing a refuse incinerator and the like.
従来のコンクリートブロックについては、耐寒性につい
ての研究はは進んでいて、品質もそれなりに向上してい
るが、耐熱性についての研究は余りなされていない。そ
れは、窯炉構築に当っては、JIS規格の耐火レンガを用
いることが常識となっており、敢えて耐熱ブロックの如
きを研究する必要がないということが１つの理由となっ
ていると考えられる。Regarding conventional concrete blocks, research on cold resistance has progressed and quality has improved to some extent, but research on heat resistance has not been carried out very much. It is considered that one of the reasons for this is that it is common knowledge to use JIS standard refractory bricks when constructing a kiln, and there is no need to deliberately study heat resistant blocks.
然るに、耐火レンガはブロックに比較して、原材料が高
いだけでなく製造工程が複雑なためにどうしても高価と
なり、また、耐火レンガは小さいために積み重ねが面倒
で手間が掛かり、築炉中に倒れやすいこともあって、耐
火レンガによる築炉作業は誰にでもできる訳ではない。However, compared with blocks, refractory bricks are expensive because they are not only high in raw materials but also complicated in the manufacturing process, and because refractory bricks are small, stacking is troublesome and time-consuming, and they easily fall down during furnace construction. As a result, not everyone can build a furnace using refractory bricks.
そこで本発明は、取扱いやすく築炉工事が容易で、充分
な耐熱性を有し、製造コストも低廉な耐熱ブロックを提
供することを目的とする。Therefore, an object of the present invention is to provide a heat-resistant block which is easy to handle and easy to construct a furnace, has sufficient heat resistance, and has a low manufacturing cost.

た。The present invention solves the above-mentioned problems with a heat-resistant block characterized by comprising volcanic ash, chamotte grains, sand, Portland cement and refractory mortar, and having a rectangular parallelepiped shape as a whole, in which grooves are formed from the side surface to the upper surface. did.
火山灰、シャモット粒、耐火モルタルが混成されている

きる。Excellent in fire resistance due to the mixture of volcanic ash, chamotte grains, and refractory mortar. Further, by constructing by inserting the steel bar for reinforcing bars into the groove, it is possible to finish more firmly.

（ブロック１個当り）の一例を示すと次の通りである。The heat-resistant block according to the present invention contains volcanic ash (mountain sand), chamotte grains (viscous brick), sand (river sand), boltland cement and refractory mortar, and its distribution rate (per block) An example is as follows.
シャモット粒は耐火度SK36のものを用い、耐火モルタル

ぜい1000℃位までにしかならないので、本耐熱ブロック
１は築炉用として十分に実用性があるといえる。なお、
溝２は、構築後の前面への倒壊を防止し、ブロック相互

入するためのものである。 Use chamotte particles with refractory SK36 and refractory mortar with refractory SK32 or higher. A general concrete block is made of cement and sand, and lacks impact resistance due to the presence of cavities. However, the heat-resistant block 1 according to the present invention has the above composition and, as shown in the figure, has a shape in which the groove 2 is provided from the side surface to the upper surface without forming a cavity, and therefore has excellent impact resistance, The compressive strength to net cross-section is about 3 times that of concrete blocks. That is, as a result of the test, in the case of concrete blocks
Whereas a 19.5kgf / cm 2 or so, when the present heat resistant blocks 1 have been found to be up to 61.0kgf / cm 2. In addition, as a result of the heat resistance test, it was confirmed that there was no problem at least up to 1100 ° C. In the case of an ordinary incinerator, the heat-resistant block 1 can be said to have sufficient practicability for building a furnace, since the temperature can be no higher than 1000 ° C at most. In addition,
The groove 2 is for vertically and laterally loading a reinforcing steel bar for preventing the collapse of the front surface after the construction and further reinforcing the adhesion between the blocks.
築炉に当っては、耐熱ブロック１を積み重ねるが、ブロ
ック相互の固定に使用する目地の厚さは、ブロック相互
の接触面積が大きいために、従来の半分の5mm程度で足
りる。そのため乾きが早く、工事時間がかなり短縮され
るメリットがある。In building a furnace, heat resistant blocks 1 are stacked, but the joint thickness used for fixing the blocks to each other is about 5 mm, which is half the conventional size, because the contact area between the blocks is large. Therefore, it has the advantage that it dries quickly and the construction time is considerably shortened.
本発明は上述した通りであって、廉価にて簡単に量産で
き、築炉用として好適なブロックが得られ、築炉工事も
容易且つ迅速に行なうことができ、しかも、強固に仕上
げることが可能なる効果がある。INDUSTRIAL APPLICABILITY The present invention is as described above, can be easily mass-produced at a low price, can obtain a block suitable for furnace construction, and can perform furnace construction easily and quickly, and can also finish strongly. There is an effect.
