摘要： PROBLEM TO BE SOLVED: To reduce burden of working in joint formation by oppositely disposing a plurality of reinforced bar ends, and placing steel fiber reinforced mortar kneading steel fiber mortar to the constant region of the circumference of the ends including a part between the ends. SOLUTION: Precast members 3, 3 are disposed at the set target position of a beam member 2 in a building. Next, a form is provided to the lower face and the side of a joining part 5, and reinforced by a support. Steel fiber reinforced mortar 9 is placed in the form. Since the transmission of tension stress is performed through the steel reinforced mortar 9 between the lower end beams 6, 6 of the precast members 3, 3 in such formed reinforced concrete structure, working joining the lower end beams 6, 6 can be completed only by placing the steel fiber reinforced mortar 9. Thus, the labor of the working can be remarkably reduced and improvement of execution can be contrived.

摘要： PURPOSE:To enhance construction properties by mounting a beam mold to the peripheral edge portion of a floor plate made of precast concrete, installing the beam mold in a predetermined position, and then placing concrete on the floor plate and inside the mold, thereby using the mold as a permanent mold. CONSTITUTION:A floor plate mold is installed at a construction site and a beam mold 14 is disposed around the mold and concrete is poured into the floor plate mold so as to fabricate a PICOS plate 11 provided with the mold 14 connected thereto by means of a pin, etc. Next, the plate 11 is placed on floor plate timbering 22 assembled in a predetermined position. Then bottom plates 16 are bent from the side faces 15 of the mold 14 and the lower end portions of the adjacent bottom plates 16 are made to abut to each other and beam timbering 23 is assembled therebelow. Concrete slabs are placed on the plate 11 and inside the mold 14, and a beam which uses the mold 14 as a permanent mold therefor and a composite floor are integrally constructed. The need for the work of installing the beam mold is therefore eliminated, and the labor required and the construction period can both be reduced.

摘要： PURPOSE:To enhance strength, frost damage resistance, uniformity of strength, etc., by incorporating each specified quantity of spherical air bubbles, a high performance water reducing agent, a super-lightweight aggregate and silica sand, in the subject hardened body of Ca-silicate-hauyne-slag system hydraulic cement. CONSTITUTION:This lightweight hardened body incorporates 5-20vol.% spherical air bubble, 2.5-5wt.% high performance water reducing agent for cement, a super- lightweight aggregate and silica sand. The spherical air bubble can be mixed by max. 25vol.% only by kneading hydraulic cement, an AE agent for bubble entraining, the super lightweight aggregate and silica sand, but the upper limit is regulated to 20vol.% because of prevention of a variation, prevention of drop of the adhesive strength to a tile and delay of neutralization by carbonation. However, a specific gravity of 1.7-1.1 aimed is not obtained by this composition, so the super-lightweight aggregate and silica sand are used together and the quantity of the high performance water reducing agent is set in such a range to prevent void generation of the kneaded product due to a high water absorption property of the former and also satisfy the incombusibility and fire resistance. Even though the ratio of water to cement is

摘要： PURPOSE:To improve the durability of concrete with dewatering easily made from the inside of placed concrete by providing small holes for paste-flowing and dewatering in sheathing formed in a layer state with plural fiber-made sheets overlapped. CONSTITUTION:A sheathing 1, in which plural fiber-made sheets are overlapped to made a layer state, is arranged on an inner side of converted framework 4. At that time, sash bars 5 are provided between an inner side surface of the framework 4 and an outside surface of the sheathing 1 to ensure paps. Moreover, small holes 2 for dewatering and paste-flowing, flowing in crossing and inside surface directions of the sheathing 1, are provided. Placing concrete causes water contents and paste, on the one hand, to be flowed from the outer side of the sheathing 1 to gaps of the fiber-made sheet to cross the sheathing 1 to be flowed outward, and on the other hand, to be flowed down in the surface direction in the frame poling board 1 to be flowed in the outside of the sheathing 1. This can make the concrete to be dense to slow down a neutralization speed, to retain alkalinity for a long period, for improving the durability of a building.

摘要： PURPOSE:To lift a slab stably and safely. CONSTITUTION:A process, in which an upper holder 2 is moved upward by a jack section 11 under the state in which a post 1 is held by a lower holder 3, and a process, in which the lower holder 3 is moved upward by the jack section 11 under the state in which the post 1 is held by the upper holder 2, are conducted alternately, thus hanging up a slab along the post. Accordingly, a machine need not be mounted at the top section of the post and the slabe be lifted, thus stably lifting the slab safely.

摘要： PURPOSE:To construct a column by using a formwork by which the overlapping of reinforcing bars and hoops is improved to obtain in-situ concrete integrated by charging concrete into the hollow formwork made of PC by centrifugal forming. CONSTITUTION:Reinforcing bars 22 are set on the inner surface side in the outer formwork 32 of a centrifugal former 30, and concrete 21 is charged for moulding, where an uneven face 25 is formed on the inner surface for integration. Double hoops 7 are provided for the hollow formwork 20. In construction work using the formwork 20, the formwork 20 is set by tapering the main bar 6 of column 2 to adjust the verticality.

摘要： PURPOSE:To improve the productivity of structuring work by constructing the highest part of a structure in the inside of a landslip preventing wall, and pushing up a constructed part using a weight lifting means in a state where it attains a fixed height and can stand for itself, and repeating these works. CONSTITUTION:After constructing a landslip preventing high wall and digging out its inside to perform foundation work, a jack 6 is installed at a position where a pillar 10 on an underground bottom is vertically set. A pillar bottom formwork 15 is then mounted on the upper face of the jack 6, and connection members 12 are set, and mutually connected through a beam 11. In the first constructing work, the beams 11 for two layers and the pillar 10 are constructed at the same time, and a supporting member 17 for horizontal force is inserted between a lateral sheet pile 4 of a landslip preventing wall and the beam 11. A main brace, a bottom formwork and a pillar formwork are then arranged between the upper and lower members 12 for depositing concrete. When the concrete becomes solid to make the self-standing of the pillar or the like possible, the jack 6 is extended to push up one layer of a structural body. The above works are repeated to construct a structure.
