(産業上の利用分野)
この発明は、鉄骨またはコンクリート建築物の壁や天井
等に、耐火、防音、断熱等を目的として岩綿をセメント
と共に吹付塗布する、岩綿吹付方法と岩綿吹付機に関す
るものである。Detailed Description of the Invention (Field of Industrial Application) This invention is a method of applying rock wool together with cement to the walls and ceilings of steel-framed or concrete buildings for the purpose of fireproofing, soundproofing, heat insulation, etc. This article relates to spraying methods and rock wool spraying machines.
(従来の技術)
従来の岩綿吹付方法は大別して■乾式@湿弐θ半湿式の
3通りの方法で行われている。(Prior Art) Conventional rock wool spraying methods are roughly divided into three methods: dry method @ wet method 2 θ semi-wet method.
■乾式は、あらかじめ用意されている、石綿繊維に油脂
を媒体としてセメントを付着させた吹付材料を空気圧送
し、吹付ガン部分で別に圧送される水と混合して吹き付
ける方法である。■The dry method is a method in which a pre-prepared spraying material, in which cement is attached to asbestos fibers using oil as a medium, is sent under air pressure, and the mixture is mixed with water, which is pumped separately, in the spray gun section, and then sprayed.
この方法は、吹付機自体は比較的簡単であるが、吹付材
があらかじめ調製しであるものであって、高価であるた
め材料費の面でコスト高となるのと、吹付時に粉塵が出
て作業環境を損うのが欠点である。In this method, the spraying machine itself is relatively simple, but the material to be sprayed is prepared in advance and is expensive, so the cost is high in terms of material costs, and dust is generated during spraying. The disadvantage is that it spoils the working environment.
@湿式は、岩綿繊維とセメントと水とを混練して泥状と
したものを圧送して吹き付けする方法である。The wet method is a method in which rock wool fibers, cement, and water are kneaded into a slurry, which is then pumped and sprayed.
この方法は泥状物を圧送するのに抵抗が極めて大きいた
め、大動力を必要とし、装置が大掛りなものとなって高
価であるため、大規模な工事でないと使い難く、小廻り
がきかないのが欠点であり、小規模業者では設備を持つ
ことが困難で一般向でない。This method has extremely high resistance to pumping mud, so it requires a lot of power, and the equipment is large and expensive, so it is difficult to use unless it is a large-scale construction project, and it is difficult to make small adjustments. The disadvantage is that it is difficult for small businesses to own the equipment, so it is not suitable for the general public.
θ半湿式は、岩綿繊維と泥状にしたセメントを別汝に圧
送し、吹付ガン部分で合体して吹き付けする方法で、前
2者の中間的な方法である。The θ semi-wet method is an intermediate method between the former two methods, in which rock wool fibers and slurry cement are pumped separately, combined in a spray gun, and sprayed.
この方法は泥状のセメントを圧送するのに湿式の場合よ
り多少楽ではあるが矢張り抵抗が大きいため装置が高価
となり、圧送ポンプが故障しやすいのが欠点である。Although this method is a little easier to pump muddy cement than the wet method, the disadvantage is that the equipment is expensive because of the large tension resistance, and the pump is prone to failure.

うようにした岩綿吹付方法である。(Means for solving the problem) In other words, a mixture of rock wool fiber and cement, similar to that used in the dry process, is continuously prepared in a spray machine without using oil or fat. The rock wool fibers are defibrated by stirring or other means, and the continuously fed rock wool fibers are moistened by spraying water as necessary, and then introduced into a mixing chamber.
Rock wool is made by continuously stirring the rock wool fibers in a mixing chamber, sprinkling the mixture with cement, sending the mixture under air pressure, mixing it with water in the spray gun, and spraying it onto the surface to be coated. This is a cotton spraying method.

A cement supply device that continuously sprinkles cement onto the rock wool fibers, an agitation mixer that mixes and adheres cement to the rock wool fibers, and a rotary valve that continuously supplies the agitated and mixed spray material in fixed amounts to the pneumatic feeding device. This is a rock wool spraying machine with a built-in

岩綿とセメントと水を用いるものである。(Function) This rock wool spraying method is an improved method of the conventional dry method mentioned above, and in the conventional dry method, a spray material is prepared in advance by adhering cement to rock wool fibers using a mixture of oil and fat as a medium. However, in the present invention, a spray material made of rock wool fibers mixed with cement is prepared using a rock wool spray machine. The materials used are rock wool, cement, and water.

。The rock wool fibers are stirred and defibrated in the rock wool hopper of the rock wool spraying machine and sent to the mixing chamber connected to the end of the screw feeder by a screw feeder installed horizontally at the bottom of the hopper.
In some cases, an appropriate amount of water is sprayed onto the rock wool fibers to moisten them during transportation in the screw feeder or near the entrance of the mixing chamber.

要する。Providing appropriate moisture to the rock wool fibers in this way makes it easier for cement to adhere to the rock wool NBm, and has the effect of preventing the generation of dust at the outlet of the spray gun during spraying. However, care must be taken as too much water will make it difficult to pump air into the spray gun.

る。In the mixing chamber, while the rock wool fibers are stirred by a mixing blade, a fixed amount of cement is continuously sprinkled from above the mixing chamber using a rotary feeder installed at the bottom of a cement potper that has a cement stirring blade inside. The rock wool fibers and cement are mixed and adhered to the cotton fibers, and the spraying material mixed with the rock wool fibers and cement is sent to the rotary valve at the bottom of the mixing chamber, and the rotary valve continuously sends a fixed amount of it into the pneumatic feed path and into the spray gun. It is pumped by air, mixed with water that is pumped separately by a spray gun, and sprayed onto the surface to be coated.

奏するものである。(Effect of the invention) Since this invention is as detailed above, the conventional dry method is
Instead of using pre-prepared spraying material, which is expensive, we use a spraying machine to spray the material while preparing it, making it extremely economical and effective for attaching cement to rock wool fibers. By spraying water instead of conventional oil to provide moisture, material costs can be reduced, and cement can be better adhered to rock wool fibers, reducing or almost eliminating dust pollution. In addition, the rock wool spraying machine is a conventional dry type with a cement supply device and stirring/mixing device added, so it is relatively simple and can be compared to the conventional wet type. Unlike large and expensive products such as semi-wet or semi-wet methods, it can be provided at a low price, so even small and medium-sized businesses can use it. This has excellent effects in terms of efficiency and economy.
