本発明は部材寸法の大きい構造物、いわゆるマスコンク
リートを施工する場合に、セメントの水和熱に起因する
温度ひびわれｆ防止する措置としてのスリット管を用い
た骨材の冷却力法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for constructing aggregates using slit pipes as a measure to prevent temperature cracking caused by the heat of hydration of cement when constructing structures with large member dimensions, so-called mass concrete. Concerning cooling power method.

練り上がり温度を低くする方法である。Generally, as a countermeasure against temperature cracks that occur during concrete construction, a brecooling method is used to lower the temperature a' of the concrete after mixing. This construction method is
The constituent materials of concrete are 2. A method in which cement, water, sand, and gravel are cooled in advance with cold water or ice, and the temperature at which concrete is mixed is lowered by using the cooled materials. It is.
ここで、冷風によシ骨材を冷却する場合、ストックした
骨材内部に冷風をいかＫして吹き込むかが重要である。Here, when cooling the aggregate with cold air, it is important to determine how hot the cold air is blown into the stocked aggregate.

る。However, 1. As a method of cooling the aggregates with the above-mentioned cold air, there is a method of blowing cold air from above or below the stock bin as shown in Figure 1 or 2, or a method of blowing cold air from above or below the stock bin as shown in Figure 3. A method of blowing cold air is being implemented.

。The present invention was made in order to solve the drawbacks of the above-mentioned 17t * rice system, and as a means for blowing cold air directly into the inn in the stock, a copper pipe with slits is installed inside the aggregate stock bin. , Upper 1fI! A slit pipe was used that allowed cold air to pass through the aggregate from the slit section of 4+Ii'. This provides a method for cooling the phase.
