摘要： PURPOSE:To make execution of work easy and to ensure transmission of stress by mounting horizontal angle brace-like connecting ends that are provided, encircling a column, to steel beams on a capital section of the column, and by placing column/beam connection concrete and slab concrete thereon. CONSTITUTION:Horizontal angle brace-like connecting ends 4a and 4a are provided to steel beams 4 and 4 so that the connecting ends encircle a column 1, to which the steel beams do not penetrate, and the connecting ends are made to mount on a capital section of the column 1. Then the column 1 and the beams 4 and 4 are united with concrete 5 and 5 for column/beam connection and concrete 6 and 6 for slab placed thereon. Thereby arrangement of column reinforcements can be made without being intercepted by steels for beams and, at the same time, transmission of stress can be ensured between the column and the beams.

摘要： PURPOSE:To make the lift-down work of each steel beam easier as well as simplify the construction work by using steel beams for the first stair and underground stair floors in which the ends of the adjacent beams are connected with each other by winding around structural straight columns with them. CONSTITUTION:Structural straight columns 3 are wound with beam ends 4a and 4'a to form a corner bracing, where steel beams 4 and 4' for the first stair and underground stair floors are built connectedly to each other. After the primary excavation, the beam 4 is lowered to a given position under the guidance of the columns 3 and temporarily supported on the columns 3, and the beams 4' are temporarily set under the beam 4. The secondary excavation is made by using the beam 4 as a shore strut, and the beam 4' is lowered to a given position and set on the columns 3 to use it as a shore strut. The same operations are repeated for construction until the lowest stair, and concrete is orderly placed from the lower stairs to construct an underground structure.

摘要： PURPOSE:To increase workability and structural reliability, by pressing concrete from a press-in hole provided into a steel pipe column or an underground beam and densely filling concrete into the steel pipe column and the underground beam through a connection hole at the junction part of both members. CONSTITUTION:After completion of a foundation 1, a steel pipe column 2 is erected and an underground beam 3 made of steel pipes is unified with the steel pipe column 2. And connection holes 4, are provided at the junction part of the underground beam 3 and the steel pipe column 2. And concrete is pressed from a concrete press-in hole 8 provided on the steel pipe pile 2 or the underground beam 3. Then concrete is continuously and densely charged fully into the steel pipe column 2 and the underground beam 3 through the connection holes 4. In this way, the steel pipe constituting the steel pipe column 2 and the underground beam 3 is used in common for both a structural member and a concrete form and it dispenses with the fabrication of forms and arrangement works of reinforcements.

摘要： PURPOSE:To improve durability and safety of an installation joint part by facilitating installation connection of a steel frame small beam by burying a gusset plate with a dowel reinforcing steel and heightening transmission performance of shearing strength to a large beam as well as workability. CONSTITUTION:By assembling and projectively providing a plural number of dowel reinforcing steel bars 6 on both side faces of a gusset plate 5 with intervals, they are buried at a small beam installation part of a half PC large beam 1. Thereafter, by projecting the gusset plate 5 from a side face of the small beam installation part of the half PC large beam 1, an installation connection part 5a with a steel frame small beam 7 is constituted.

摘要： PURPOSE:To provide rational and economical trussed girders which are provided with sufficient strength against tensile force, maintaining high strength against compression force. CONSTITUTION:When constructing trussed girders 1 formed by connecting steel pipe-made upper and lower chord members 2 and 3 to diagonal members 4, concrete 5A is placed in a hollow of the lower chord members 3 which serves as a tensile material and then a load W equivalent to an external force is made to act in the opposite direction of the external force while concrete 5B is subsequently placed in a hollow of the upper chord members 2 which serve as a compression member during the application of the external force. After the concrete 5B is cured, the load W is released.
