摘要： PURPOSE:To prevent drying shrinkage of lumber and to greatly reduce corrosive influence to iron material, etc., by treating lumber with an aqueous liquid agent in which the water-soluble compd. of alkaline earth metal and a chromic acid compd. are dissolved and impregnating lumber with the specified weight of the water-soluble compd. of alkaline earth metal. CONSTITUTION:Lumber is treated by utilizing an aqueous liquid agent in which the water-soluble compd. of alkaline earth metal and a chromic acid compd. are dissolved. In this case, the liquid agent is injected so that the impregnated amount of the water-soluble compd. of alkaline earth metal for lumber is regulated to at least 7kg by weight of solid material per 1m lumber. By this method, lumber is obtained wherein corrosiveness for iron, etc., is reduced and drying shrinkage is effectively prevented.

摘要： PURPOSE:To facilitate conveyance and construction by erecting click-shaped projections on the bottom surface of a metallic bed plate having the rise walls of a specified level on both side edge sections, in the shape of a ring, and by driving a plurality of wooden block bodies on the bed plate to be connected to each other. CONSTITUTION:On both side edge sections of a metallic bed plate 2, the rise walls 2d of the thickness of 0.5-0.25 of that of wooden blocks 1 are continuously arranged. Through the bottom surface of the bed plate 2, a slot 2a is bored, and on the periphery, a plurality of click-shaped projections are erected. Besides, on the bed plate 2, a plurality of the wooden blocks 1 are driven at specified intervals to be connected to each other. Then, with a plurality of the wooden blocks 1, integrated bodies for pavement are formed. As a result, conveyance and construction are facilitated, and durability can be improved.

摘要： PURPOSE:To stabilize soil surface without damaging its beauty appearance until plant is rooted in the greens-planting work by providing auxiliary materials inclined at 45-90 deg. to a slope and having a height of 20-90% of the fame in the frame for greens-planting work. CONSTITUTION:A square outer frame 1 for a frame A is formed of 4 wooden plates 1a-1d subjected to a preservative treatment. Also, the auxiliary materials used are inclined at 45-90 deg. to a slope where the outer frame 1 is set and their heights are designated to 20-90% of that of the frame 1. Thus, the surface of soil even in the frame 1 can be stabilized against degradation, etc., caused by rain.
