摘要： PURPOSE:To remarkably lighten concrete floor beds and increase its rigidity at the same time and further, rationalize the construction process by simplification of processes. CONSTITUTION:Shear connectors 2, 3 are protruded at the upper and lower faces of a honeycomb core material 1 to superimpose a concrete bed 5 through the shear connector 3 of the underface. A half-precast concrete floor bed 6 sealed up 4 is used at the upper side face of respective cores 1a. This half- precast concrete floor bed 6 is placed between beams. Later placed floor concrete 9 is applied so as to bury the honeycomb core material as a floor frame.

摘要： PURPOSE:To display the faculty of a lead itself to enable the precise evaluation of its characteristics by arranging a binding plates in a direction crossing a section where a shearing strain occurs at right angles, and connecting the adjacent binding plates through a hinge so as to be rotatable round a shaft perpendicular to the section where the shearing strain occurs. CONSTITUTION:Binding plates 2 are arranged in a direction crossing a section, where shearing strain gamma occurs in the acting direction of shearing force as shown in the figure, at right angles. Namely in the case where the binding plates 2 receive external force as horizontal force, they are arranged so as to form a plane crossing a vertical plane including the acting direction of the external force at right angles. In addition to that, the adjacent binding plates 2 are mutually rotatably connected through a hinge 3 round a shaft vertical to a section where the shearing strain occurs, in this case round a shaft vertical to the vertical plane including the direction of the external force. Thus the binding plate 2 restricts the volumetric change of a lead itself as it freely follows the deformation of the lead itself.

摘要： PURPOSE:To make it possible to absorb vibration energy by inserting a core projected to the other of structural members into a hollow section of an outside frame projected to one of them so that it is capable of rotation, and enclosing a lead mass between the outside frame and core so that it is capable of plastic deformation. CONSTITUTION:A revolving body 5 is projected to one of connected structural members and, at the same time, revolving bodies 6 are projected to the other of them. A rectangular coupling bolt 7 is inserted into a hollow section 3 of the revolving bodies 5 and 6, and fixing nuts 8 are screwed to male screws on both ends thereof. In addition, a lead mass 4 is enclosed into the hollow section 3. The lead mass 4 makes plastic deformation in accordance with relative rotary deformation amount in the time of relative deformation between the structural members, and vibration energy of a construction is absorbed.

摘要： PURPOSE:To prevent a plate from jolting by making an outer diameter of the band plate to be set up in a steel pole be more smallish than an inner diameter of the steel pole, and filling up a clearance between the plate and a steel frame in and around a bolt with resin. CONSTITUTION:A band plate 3, whose outer diameter is more smallish than an inner diameter of a steel pole 1, is set in the steel pole 1, and an outlet part is temporarily clamped by an erection bolt covered with a rubber film. Next, when liquid epoxy resin 7 is injected from an inlet of the bolt, this resin 7 goes out of the outlet, having the rubber film expanded in a clearance 5. Then, when the resin 7 is hardened, the erection bolt is pulled out and a regular bolt 6 is screwed therein instead.

摘要： PURPOSE:To prevent the melting-down of joints as well as eliminate the needs for backing metal by a method in which an opening of a width similar to that of the cross section of a reinforcing material is formed in the thickwise direction of plate, and both ends of a reinforcing material in contact with the inside of a column are cut in parallel with side faces in contact. CONSTITUTION:A reinforcing material 2 is set between adjacent sides in an angular steel tubular column 1, and both ends of the material 2 are welded to the peripheral side of an opening 1a formed on the side to reinforce the column 1. In this case, the width of the opening 1a is equalized to the width of the cross section of the material 2, or is equalized to or made slightly greater than the diameter D of a steel bar or the thickness (t) of plate. Also, both ends of the material 2 are cut in parallel with the side of the column 1 in contact, or in the direction of 45 deg. to the width (thickness or radius) of cross section, where the width of the end face is regulated to be the width (t) of the opening 1a or root 2 times D.

摘要： PURPOSE:To prevent the performance drop of a planar damper by connecting Z-shaped deformation absorbing plates which expand and contract in the in-plane direction to both ends of the planar damper to be housed in the vibrational energy absorbing wall of a structure and reducing the displacement of the damper in the out-of-plane direction. CONSTITUTION:Deformation absorbing plates 1 are firmly fixed to both ends of a planar damper D which is provided between structures S and absorbs vibrational energy by making elastic and plastic deformation in the in-plane direction by utilizing the relative displacement between both structures S. Each of the plates 1 is folded to a Z-shape in cross section and equipped with fitting flanges 2 at both ends. The plate 1 is elongated like a spring when a force acts on the structures S in the out-of-plane direction (shown by the arrows A) of the damper D. Therefore, the deformation of the damper D can be prevented and the performance of the damper can be secured.

摘要： PURPOSE:To make simple, but strong connection of beams feasible by a method wherein a connecting hardware in parallel crosses shape in dimensions roughly the same as the interior dimension of a closed section type steel column is inserted to the inside thereof and after this, end parts of beams are connected thereto with bolts screwed down to tapped holes that are provided in advance to the connecting hardware. CONSTITUTION:A connecting hardware 7 in parallel crosses shape in dimensions roughly the same as the interior dimension of a closed section type steel column such as a box column or the like is made up by casting and holes 8 are tapped on the end parts thereof. In a factory, the hardware 7 is inserted into the inside of the column 1 and after setting the same horizontal thereat, temporary fixing is made with temporary bolts inserted into bolt holes 9 that are bored in advance. After erecting the column 1 in a site, bolts 10 are inserted into connecting plates 11 and 12 on the end parts of steel beams 4 and are screwed down to the holes 8 of the hardware 7. The hardwares 7 may be inserted in advance in a plurality of stages with connection made with tie rods 7'. Thereby difference in level will not occur like in the case of conventional method where tightening is made with long bolts, making smooth transmission of stress possible and, at the same time, labor saving becomes possible in execution of work.

摘要： PURPOSE:To make easy execution of work possible in load transmitting pert corresponding to diaphragm by planting stud bolts to internal peripheral faces of a closed section type column or positions to which beams are connected. CONSTITUTION:To positions to which beams are connected on two side faces adjoining each other of a column, holes 6 in the height about half the height of the beam and in the width the same as that of the beam are provided. And to positions corresponding to flanges of the beams on the internal faces of the column 1, stud bolts 5 are planted by operation executed through the holes 6 and after this, the holes 6 are closed by welding with covers 8 having the bolts 5 and divided into two pieces. In another instance, the bolts are planted to the internal end external peripheries of the holes 6 provided to the column 1 by operation executed through the holes snd after this, hollow and box-shaped beam-installing brackets are installed thereto and are made integral with the column with concrete placed to the inside thereof. And in the third instance, split bolts 10 whose tips split with pulling rods 13 pulled backward are provided and are inserted into the inside of the column 1 through the holes thereof and are made to split. After welding both the column and the bolts together, concrete is placed thereto. Thereby smooth transmission of load can be made possible and work can be executed easily.
