摘要： PURPOSE:To increase the rigidity of a wall body by forming a reinforcement body of a concrete wall to be a cell type structural body consisting of vertically continuous small chambers connected with each other along the width, inserting spiral reinforcements in the small chambers, and placing concrete. CONSTITUTION:H-section steel 7 is installed continuously in a dug groove, and adjacent flanges 9 of the H-section steel 7 are connected with each other by connecting steel plates 12, so a cell-type structural body 5 including a number of small chambers 5a is formed. Spiral reinforcements are then inserted into each small chamber 5a. Concrete is then placed inside and outside the cell-type structural body 5 for improving the rigidity of a wall body and keeping the wall thickness thin. A wall construction cost can thus be reduced.

摘要： PURPOSE: To control the temperature of ice to be made over a wide range while simplifying the system and reducing the facility cost by supplying liquefied gas to the inside and supplying liquid to the surface of an entirely cooled hollow rotator. CONSTITUTION: Liquefied gas 3 is supplied from a liquefied gas tank 10 into a drum 1 by turning the drum around the rotary axis thereof. The liquefied gas 3 cools the tank 1 entirely down to 0 deg.C or below from the inside and it is partially vaporized to produce low temperature gas. The gas is discharged through an exhaust pipe 30 into the water 5 in a water storage tank 20 and the water 5 is cooled preliminarily. Furthermore, the water 5 is ejected from the tank 20 through nozzles 23, 23,... toward the surface of a drum side plate 1a. Consequently, the water 5 is frozen while being atomized to produce ice of small grain size. The ice is then stripped from the surface of the side plate 1a by means of an edge 7 and stored in an ice storage box through a collector located below the edge 7.
