摘要： PURPOSE:To perform free support even when an inclination beam and an angle brace are brought into contact with a wale at any angle, to eliminate a need for placing of concrete, and to simplify execution of a work by a method wherein an angle piece of a specified up angle is attached to the wale and a rotary metal composed of male and female members is fastened thereagainst by means of a bolt. CONSTITUTION:A rotary metal 20 composed of male and female members 24 and 29 is attached on a flange surface 51a of a wale 51 through an angle piece through an angle piece 64. A temporary support stand P is installed in the same level as that of the wale 51 on an excavating surface G. The rotary metal 20 is fastened against one end face of a strut main material 52, a hydraulic jack 56 is attached to the other end part, and the rotary metal 20 is fastened against the tip of the jack by means of a bolt. The work is executed in a state that the main material 52 is maintained in a horizontal state. The main material 52 fabricated on a ground is lifted and fastened against an angle piece 59. A strut is arranged in a manner to oscillate both horizontally and vertically. This method eliminates a need for fixing made by means of concrete since a joint is fastened by means of a bolt and executes rapid mounting and demounting work.

摘要： PURPOSE:To improve the structural strength by fixing cross form connecting metals to hold the web of an iron frame beam to a post reinforcement basket, and setting a closed metal being a mould concurrently between them, and furthermore, fixing timbering plates at the inner side. CONSTITUTION:In a post reinforcement basket 1, a pair of crossform metals 8 to hold the web of an iron frame beam D are fixed at the upper side and the lower side. Then, between the connecting metals 8, a closed type plate metal 4 of the reinforcement basket 1 being a mould concurrently is provided. Furthermore, at the inner side of the plate metal-cum-mould metal 4, timbering plates 7 are fixed to reinforce the metal 4 so as to prevent a deformation owing to a bending moment from the iron frame beam D. As a result, the strength of the connection between the post and the beam can be prevented.

摘要： PURPOSE:To increase the strength of a joining section by approaching up and down parts of a beam joining metal fixtures to bury a frame shaped band plate in which a column main reinforcement is involved and arranging a fence- like molded hoop to a connection. CONSTITUTION:Beam joining metal fixtures 2 with an enclosed type section are buried under the beam joining section of a reinforced concrete column 1 in a plurality of steps so as to continue a hollow section of the beam joining metal fixtures in the vertical direction. After that, a frame shaped band plate 9 is buried by approaching up and down parts of the joining metal fixtures 2. A main reinforcement and hoop are respectively arranged to the inside and outside of the joining metal fixtures, and steel frame beams 3 are joined to the sides of the beam joining metal fixtures 2. In addition, the hoop arranged to the outside of the joining metal fixtures is formed in the shape of a fence.
