摘要： PURPOSE:To dispense with the accessary works such as a boring for bolts, a welding and an installing of an auxiliary metal fitting, and the like when a working table, a timbering stand, and the like are assembled, by forming a boss a pair of opposing bolts are screwed, on both sides holding the groove of a groove form metal fitting, and screwing the bolts to the boss. CONSTITUTION:When the component members of a working table or a timbering stand are assembled, in the assembling time of the working table, the timbering stand, or the like, the flange A of a member to be connected is fitted to the groove of a groove form metal fitting 1 of the first assembly jig having a reinforcement rib in the longitudinal direction, and the flange A is pressed and held by a pair of bolts opposing each other and screwed to the boss of the metal fitting 1. And at one end of the groove form metal fitting 1, the plate form part 4 of the first assembly jig, and the flange B of another member to be connected are held and fixed by a C type assembly jig. In this case, when the holding force of the first assembly jig is to be increased, the groove form metal fitting 5 of the second assembly jig having a reinforcement rib in the longitudinal or the peripheral direction is installed to contact one end of the first assembly jig in the same manner, so as to press and hold the flange A.

摘要： PURPOSE:To eliminate unnecessary pads by increasing the radius of curvature at each corner part of the inner periphery of a U-shaped plate member, and forming the outer periphery in a parabolic shape, and also by providing tapered reinforcement ribs. CONSTITUTION:The inner periphery of a U-shaped plate member 1 is formed to have a large radius of curvature at each corner part thereof so as to intrude into the inside of the plate member 1 in such a way that the fillet is slightly scraped out, and the radii of curvature at two corner parts are smoothly connected with a further larger radius of curvature to form the deep part of the U-shaped plate member. Then, the depth measured from the opening along the one side of the U-shaped plate member is made equal to the distance up to the intersection C of the tangent of the further larger radius of curvature in the deep part. Then, insertion holding bolts 2, 2' are screwed into the threaded holes formed in the bosses 3, 3' that have been provided in the respective ends of the U-shaped opening. The outer periphery of the U-shaped plate member is bulged toward the outside in a parabolic shape making the apexes of the bosses 3, 3' for equalizing the stresses. Further, tapered reinforcement ribs 4 are radially provided toward the outer periphery from the inner periphery corner parts so as to cope with the stress concentration in these portions.

摘要： PURPOSE:To firmly fix assembling members butt-jointed and make sturdy a working bed, a temporary supporting base, etc., made of assembling members. CONSTITUTION:An assembling tool is composed of a first tool 4 provided with two fastening bolts 3 to bite both assembling members 2, 2 and fasten them to directly fix both assembling members 2, 2 and a second tool 6 provided with two firmly fastening bolts 5 to further fasten the two fastening bolts 3 in the first tool 4 to make firm the fastened both assembled bolts 2, 2 by both fastening bolts 3 of the first tool 4. The fastening force of both assembling bolts 2, 2 by the fastening bolts 3 of the first tool 4 is made firmer by the further fastening bolts 5 of the second tool 6 in order to firmly fix the assembling members 2, 2.

摘要： PURPOSE:To attain weight reduction and miniaturization by the use of high strength steel and omit machining work so as to decrease the cost by manufacturing a steel formwork fastening jig by forging. CONSTITUTION:A clamp 1 and a receiving metal fitting are formed by forging, and a bolt and a long nut 12 being solded on the market are utilized for a clamper 7. All the pivotal fitting parts by pins 5 are caulked so as to reduce manhour. The clamp 1 is to one formwork and the receiving metal fitting is to the other formwork welded, and this jig is constituted so that the formworks are fastened together by standing and falling of a lever 4 through a T-shaped hooking metal fitting.

摘要： PURPOSE:To install bracing materials to symmetrically diagonal positions even though eccentricity or twist exists in supports by a method wherein two pairs of bolts for clamping an H-steel and a pair of bolts for clamping an angle steel are held with bosses. CONSTITUTION:Two pairs of bolts 7, 7, positioned opposite to each other and capable of clamping a flange of an H-steel B independently on the right and the left, and a pair of bolts 8 for clamping an angle steel A are provided. All of those bolts 7 and 8 are held with bosses 1.... A jig for erecting a temporary structure made up as mentioned above is equipped with three clamping parts, and the flange of the H-steel B serving as a support can be clamped with the clamping parts on either the right or the left while the angle steel A serving as a bracing material can be installed, inclined symmetrically to the right and the left. Therefore, preparation of jigs in two different types in accordance with convenience in use becomes unnecessary, and installation of bracing materials can be executed even though eccentricity or twist exists in the H-steel serving as the support.
