性、及び耐水性にすぐれた軽量気泡コンクリート版の製
造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a lightweight cellular concrete slab based on a flat-casting method, in which the mold bottom plate release surface is used as the product surface, and smoothness, designability, and water resistance are maintained. The present invention relates to a method for manufacturing an excellent lightweight cellular concrete slab.
軽量気泡コンクリートとしてはＡＬＣ、プレフオームに
よる軽量気泡コンクリート版等がある。Examples of lightweight cellular concrete include ALC, lightweight cellular concrete slab made of preform, and the like.
（従来の技術） 従来軽量気泡コンクリート版で離型剤で離型した面をそ
のまま製品面としているものはほとんどなく型枠離型面
をピアノ線などの切断線で切り落とすか、又はオート養
生後切削加工し、表面を出していた。(Prior art) There are few conventional lightweight cellular concrete slabs that have the release surface as the product surface, and the mold release surface is cut off with a cutting line such as a piano wire or cutting after auto curing. It was processed and the surface was exposed.

ことは品質的にも、経済的にも適切な方法ではないと考
えられていた。This is different from concrete such as PC plate, in the lightweight cellular concrete mortar, the strength of the mortar block itself is several times weaker, and when the mold is released from the mold, the mold releasability cannot be removed without a defect unless the mold releasability is greatly increased. And the mortar viscosity
It is as low as 300 to 1000 centipoise. The injection of this mortar causes the mold release agent to flow, and the part where the mold release agent has flowed is the chipping defect of the block and the part where the released mold release agent has accumulated is the mortar unreacted part defect. Therefore, it was considered that it is not an appropriate method in terms of quality and cost to use the mold bottom plate release surface as the product surface in lightweight cellular concrete.

かつた。すなわち第２図の(a)によく似た、原型の面が
忠実に、版表面に反映されていないものであつた。Some of the relief plates had a mold release surface on one part, but defective parts due to oil entrapment of the mold release agent were conspicuous, and mortar peeling occurred due to poor mold release. Furthermore, the pattern of the plate obtained was not clear, and the sharp pattern obtained by concrete plates and the like was never obtained. That is, the original surface, which is very similar to that shown in FIG. 2 (a), is not faithfully reflected on the plate surface.

によるということになる。(Structure of the Invention) The gist of the manufacturing method of the present invention is that, in the method for manufacturing a lightweight cellular concrete slab by a flattening method, a mold release agent is uniformly applied to a mold bottom plate at 20 to 60 g / m 2 , and mortar is applied to the mold bottom plate. It is characterized in that the mortar injection port provided in the injector is brought close to the form bottom plate and the mortar is injected along the form bottom plate without directly dropping. The lightweight cellular concrete slab obtained according to the production method of the present invention has at least one plate surface of the plate product surface, as shown in the example of FIG. Will have. Adjacent parts of the prototype part 2 are substantially linear with each other, and it depends on the plane accuracy of the mold used.

The impregnated layer can increase water resistance and water resistance. When a film-like release agent such as PVA is used, the release agent-impregnated layer cannot be obtained. The impregnated layer here can be identified as follows. 1). Distinguish the layer by the color change of the release agent during auto curing. 2) Identify the presence or absence of the layer by comparing the water permeability. 3) A method such as identification based on changes in crystals due to powder X-ray diffraction.

しい。The release agent in the present invention is a mineral oil, a dispersion of a surfactant such as a metal soap in a mineral oil, silicone oil,
A low molecular weight polyethylene is dispersed in mineral oil, and a thixotropy imparting agent (calcium charcoal, silica, etc.) and a membrane strengthening retainer (polyisobutylene, etc.) may be added as additives. There is no particular limitation as long as it can be uniformly applied. Further, a film-type release agent such as polyvinyl alcohol may be used. A mold release agent with a viscosity of about 120 seconds (using a Viscotester at 30 ° C) is obtained by dispersing metal soap, sulfonate, and polyisobutylene in mineral oil that forms a non-drying oil film due to the cost of the mold release agent and the ease of application. More preferable.

The amount of coating per m 2 of the mold is set in advance, and the amount is applied to the bottom plate of the mold by spraying or coating with a mop, and then evenly spread over the entire bottom plate surface with a roller. It should be noted that the amount to be applied in advance may be made more than the final required amount, and the excess release agent may be squeezed out in the next roller treatment, but only the required amount is applied in advance by spraying, etc. and evened out with a roller. It is very preferable. Also, a uniform coating film can be obtained by a method of securing a predetermined amount of release agent with an intaglio plate, transferring it to a rubber roller as in the offset printing method, and further transferring it to the mold bottom plate. Any roller that has oil resistance and a soft surface may be used, but among them, mohair rolls,
A roll having an oil retaining property such as a felt roll or a polyurethane sponge roll is more preferable.
離型剤の型枠底板への塗布量は２０〜６０g/m2が好まし

注入条件となる。Next, as shown in the examples of FIGS. 3 and 4, the mortar is injected into the mold bottom plate applied by the above-mentioned method so that the mortar inlet is close to the mold bottom plate, and the mortar is along the mold bottom plate. To inject. As a result, it is possible to prevent the mortar block from being damaged due to the release of the release agent at the time of injecting the mortar, and it is possible to manufacture the lightweight cellular concrete slab having a release surface faithfully copying the above-mentioned mold bottom plate surface. More preferable injection conditions are to inject along with the mold bottom plate and to make the injection mortar have a gentle flow rate of 8 / min · cm 2 or less at the injection port flow rate.

フイルムの厚手のものを用いた。(Example) ALC mortar slurry using aluminum as a foaming agent mortar was applied to a mold having internal dimensions of 1.8 M width x 3.0 M length x 0.2 M height using the injector 7 shown in Fig. 3. Mortar was injected along the form bottom plate surface with the inlet close to the form bottom plate surface. At this time, a small amount of metal carboxylate, sulfonate, and polyisobutylene were added to mineral oil on the bottom plate of the mold. A mold release agent (specific gravity: 1.1) having a viscosity of 120 seconds (30 ° C. Viscotester) was applied with a mop, and thereafter evened with a mohair roller. After that, the release agent was wiped off and the applied amount was examined and found to be 40 g / m 2 . Also, the third
In the injector shown in the figure, mortar is made to flow from the mortar supply pipe of 14, and it is stocked in the injector shown at 1 o'clock for 1 hour to remove foreign substances with a wire net, etc., and then injected into the bottom plate of the mold along with the injection guide plate of 8. . 9 is a presser guide for not disturbing the flow. The reason why the main body of 7 is not in close contact with the bottom plate of the mold is that injection can be performed even if a reinforcing steel basket exists under the main body of 7. As the material shape of the guide plate 8, a material having a steel property, flexibility, and capable of being retained in the S shape of 8 in FIG. 3 was used. That is, it is made of plastic and is molded into a thin S-shape. It may be a resin coated end portion with a tin plate. As the material of the injection presser guide 9, a thick vinyl chloride film was used.

ノ線切断面は１分であつた。After the mortar has been injected up to a height of 9 cm from the bottom plate of the mold, after the mortar has been foamed and the mortar has been pre-cured, the mold side plate is demolded, the upper surface of the mortar is cut off with a piano wire, and then vacuum suction is applied to the mold. The mortar block was detached from the frame bottom plate. Then, autoclave curing was performed to obtain a large ALC plate having a wall thickness of 125 mm. The appearance of the mold release surface is free from bottom peeling, defects, and hardening defects due to oil entrapment, and its surface area is magnified 10 times, and the cross section is observed as shown in 2 of (a) of Fig. 1. As shown, it has a mold release surface having a mold bottom plate original part, and a plate with a solid appearance similar to the concrete casting plate was obtained. Further, it was confirmed that the mold release surface had good water resistance as follows. The time required for dropping 1 cc of water on the plate to absorb water was measured. The mold bottom plate releasing surface required 10 minutes, while the piano wire cutting surface took 1 minute.

でより好ましい。Also, after removing the upper surface mortar by cutting with a piano wire, it was put into the autoclave together with the form bottom plate, but this also had the same good appearance as the above, without the form bottom plate and mortar adhering. A plate was obtained. The method of curing the entire mold bottom plate is more preferable because it is less likely to cause defects when the mortar and the mold bottom plate are detached from the block and the pre-curing time can be shortened.
