摘要： PURPOSE:To obtain a relatively light weight and high-strength planter to grow a large-sized tree. CONSTITUTION:A planter has an inner column 14 comprising heat insulating concrete placed inside an outer column 12 made of concrete mixed with a fiber material, the outer column 12 shows strength and the inner column 14 maintains heat insulting properties. Since an extending part 12A formed on the top of the outer column 12 covers the top part of the inner column 14, edge part causing deficiency in strength in the case of a large-sized planter is surely reinforced. In manufacture, since rubber 56 is applied to the inside of a mold frame 54 composed of veneered wood to make a mold frame structure, the outer column 12 and the inner column 14 are placed, even the large-sized planter is readily manufactured.

摘要： PURPOSE:To improve quality by a method wherein, after the part of a columnar steel frame is filled with concrete and the concrete is cured to form a half precast column material, a columnar material is driven, and reinforcing bars are arranged and cast-in-place concrete is placed. CONSTITUTION:A columnar steel frame 1 is manufacture in a shop, and a partitioning material 10 for construction, e.g. expand metal, is welded between flanges. At a field, concrete 12 is placed between the flanges of the columnar frame steel 1 and cured to form a half precast columnar material A. The columnar material A is driven in a site, and the leg part of the columnar frame steel 1 is joined with the columnar steel frame at a subsequent lower floor. A precast large beam is then driven, joining of steel frames and joining of main reinforcing bars are effected. Columnar reinforcing bar assembly is effected at 2 and 7 around the columnar material A, a half precast slab is spanned between the large beams, and after columnar form assembly is effected, cast-in- place concrete 9 is placed.

摘要： PURPOSE:To easily manage the quality of high strength concrete by measuring the settlement of concrete in a reservoir part, or the moving amount of concrete in a flow part, and the drift velocity of concrete. CONSTITUTION:At the time of executing a quality test of concrete, a vertical part 10 is filled with concrete of a prescribed quantity in a state that an opening 16 has been closed by a partition plate 14, and subsequently, by drawing up the partition plate 14, concrete is allowed to flow to a horizontal part 12 from the opening 16. In this case, a time point when a deformation of concrete is started is a time point when the partition plate 16 has been drawn up, and a time point when the deformation of concrete is ended is a time point when the movement of concrete in the horizontal part 12 has stopped, and both of them can be discriminated clearly. In this state, by measuring a moving amount of concrete in the horizontal part 12 at the time point when the deformation of concrete has been ended, a yield value is derived. Also, by dividing the moving amount by the time extending from the time point when the partition plate 14 has been drawn up to the time point when the movement of concrete has stopped, and measuring a drift velocity of concrete, viscosity is derived.

摘要： PURPOSE: To form a concrete shell of a large span easily by stretching a rope or net consisting of nonmetal long fiber in a space position, and placing concrete in a manner burying the rope and net. CONSTITUTION: A rope 1 or net 2 consisting of nonmetal long fiber such as carbon, aramid, and vinylon is stretched in a space position in which construction of a shell structure is planned. Following this, concrete 5 is placed so that the rope 1 and net 2 are buried to construct a shell structure. Thereby nonmetal long fiber which does not corrode different from iron bars, a cover thickness of the concrete 5 for corrosion prevention can be reduced, as a result, a concrete shell structure of a large span can be formed easily without the use of timbering.
