ツキが生じゃすｂものであった。In the conventional curing method for hydraulic cement boards, the raw hydraulic cement boards are loaded onto pallets after being made into paper, and the stacked raw hydraulic cement boards are placed in a box-shaped curing chamber where the temperature and humidity are controlled using only steam. Generally, it was controlled. However, it has been difficult to maintain a constant temperature-humidity balance by using steam to absorb moisture and water heat generated from hydraulic cement raw boards by controlling only steam in this way. As a result, cracks were generated at the edges of each hydraulic cement board, resulting in considerable variations in quality.
本発明は上述した背景技術に鑑みてなされたものでその
目的とするところは端部クラック等が発生しな−ように
し水硬性セメント板の品質の安定した養生方法にある。The present invention has been made in view of the above-mentioned background art, and its object is to provide a curing method that prevents the occurrence of edge cracks and the like and stabilizes the quality of hydraulic cement boards.
以下、本発明の実施例に基づｂて説明する。 Hereinafter, description will be given based on examples of the present invention.

るので端部クラックも発生することがない。After making hydraulic cement green boards using a Fourdrinier type or circular net type paper making machine, they are loaded onto a valley J, and the loaded hydraulic cement green boards are transported to a curing warehouse. As shown in Figure 1, curing water A is prepared by suspending a sheet 1 made of water-retaining cloth or the like from the inner surface of the curing water body, and surrounding the upper three surfaces of this water-retaining sheet 1. A water spray nozzle 3 is attached to the pipe 2 so as to form a water film 4, and a steam discharge section 5 formed of a pipe with a number of holes in the lower part of the sheet 1 having water-retaining properties. This is due to the structure provided with this. The hydraulic cement board conveyed into this curing 11fA is subjected to primary curing due to the water film 4 being formed by the water spray nozzle 3 and the steam intermittently sent out from the steam discharge part 5 to maintain an atmospheric temperature in the curing chamber A of 20 to 60°C. , humidity 6
It is cured for 4 to 20 hours at 0 to 80 mm. After that, as a secondary curing, the temperature is 50 to 80℃, the humidity is 100℃, and the temperature is 48 to 10℃.
Cured for 0 hours. Therefore, the temperature inside the curing chamber A is controlled by the water film 4 of the water spray nozzle 3 and the steam, and the humidity is kept constant by the water-retaining sheet 1. Therefore, the internal temperature and the temperature at the end of the hydraulic cement board can be kept constant even in the upper and lower stages of the pallet, so that cracks at the ends do not occur.

方法である。As described above, the present invention suspends a water-retaining sheet on the inner surface of the hydraulic cement green boards loaded on a pallet in the curing water, and further surrounds the upper part of this water-retaining sheet. A water spray nozzle is used to form a water film, and a steam discharge section is provided at the bottom of this water-retaining sheet to control the temperature and humidity using the water film and steam. Since the internal temperature and humidity can be kept constant between the upper and lower layers, products with uniform quality can be obtained without the occurrence of cracks at the edges of the hydraulic cement board. It is also a simple method to maintain curing water.
