摘要： PROBLEM TO BE SOLVED: To enable improvement of a flexural strength of the connecting part of a pier and a footing without impairing the strength of the footing, by a method wherein a reinforcing steel sheet reinforcing the pier and the footing of the foundation are made monolithic by encasing concrete. SOLUTION: Reinforcing steel sheets 7 are lined in the shape of a vertical tube surrounding a pier 1a formed of reinforcing bars 3 and concrete 4. A plurality of studs 8 are provided in projection on the outer peripheral surface of the lower part of the reinforcing steel sheets 7. A plurality of insertion bars 9 are planted on the upper side of a footing 2 formed of reinforcing bars 5 and concrete 6. Then, the studs 8 provided in projection on the reinforcing steel sheets 7 and the insertion bars 9 inserted into the upper side of the footing 2 are made monolithic by encasing concrete 10. Thereby the load in the axial direction of the reinforcing steel sheets 4 is transmitted to the footing 2.

摘要： PURPOSE:To solve the problem on strength, dispense with boring of reinforcement through hole, coupling construction with a coupler, and bending work of reinforcements, and facilitate the construction. CONSTITUTION:The axial force acting on a lower floor plate reinforcement 5 is transmitted to a stud 7 through the concrete 10 around the stud 7. Further, it is transmitted to the side walls on the sides of a side wall outside steel plate 1 and a wall inside steel plate 2 from the stud through a cover plate 3. Therefore, the load transmission from the lower floor plate reinforcement 5 to the side walls can be smoothly performed.

摘要： PURPOSE:To shorten the time required to adjust height of a handrail by previously setting a coupling sleeve on a steel floor base and assembling a steel plate main body for concrete filling in such a way to cover the coupling sleeve over from its upper part. CONSTITUTION:A coupling sleeve 7 is previously set on a steel floor base 4 through an adjustment liner 9. Then, a steel plate main body 1 is assembled in such a way to cover the coupling sleeve 7 over from its upper part. Then, after completion of assemblage, water-stop sealing is applied and concrete is placed inside the steel plate main body 1. Consequently, it is possible to set a wall handrail without worrying about adjustment of the height of the steel plate main body 1, and accordingly possible to effectively set it without a heavy machine.

CONSTITUTION:Studs 2 having the length of the clearance of walls, the inner clearance of oppositely faced steel plates, are implanted at the predetermined locations of one steel plate 1 in a factory. The steel plate 1 is bent in a U shape in a fixed bend radius at a specified position. The steel plate 1 is placed onto a bottom force 3, a top force 4 is pushed against the steel plate and pressed down by a rod 5, and the steel plate 1 is curved in the U shape. The steel plate is curved, and the push rod 5 is drawn out upward and the top force 4 in the horizontal direction, then completing press. The U-shaped steel plate 1 is installed into steel-plate hold-down forms 6, the head sections of the studs 2 and the opposed steel plate 1 are brought into contact, and side end-section forms 7 are mounted and concrete 8 is placed into an internal space formed by the U-shaped steel plate 1 and the end-section forms 7. Placed concrete is cured, the steel-plate concrete wall body is carried to a cite, and turned over at 180 deg. and set at a predetermined location, thus forming an inverted U-shaped precast steel-plate concrete wall body.

摘要： PURPOSE:To save manpower and labor by providing a dynamic vibration damper accelerometer for detecting the acceleration of the weight of a dynamic vibration damper itself, a structure accelerometer for detecting the acceleration of the structure to be damped, a phase difference detecting circuit, and a frequency control means for controlling the phase difference to be kept to the set value. CONSTITUTION:The sine waveform acceleration signal A1 of a cross beam 1 and the sine waveform acceleration signal A2 of a dynamic vibration damper outputted by accelerometers 9, 10 are respectively converted into rectangular waveforms of identical amplitude through amplitude stabilizing circuits 13, 14, and both waveforms are then multiplied by a multiplying circuit 15 to obtain the value proportional to the phase difference with the phase 90 deg. as a center. The output value of the multiplying circuit 15 is compared by a comparing circuit 16, and when the output value is positive, it means that the phase is less than 90 deg. and therefore the characteristic frequency of the dynamic vibration damper is larger than that of the cross beam 1. Accordingly, a signal corresponding to the output value is outputted to move a weight 4 downward through a pulse transmitting circuit 17 so as to lengthen the length of the pendulum rod 3 of the dynamic vibration damper. The frequency of the dynamic vibration damper is thus conformed to the characteristic frequency of the cross beam 1 automatically to damp the cross beam 1.

摘要： PURPOSE:To simplify initial construction and subsequent repairs by constructing a wall balustrade with concrete placed between two steel plates that are installed at intervals and fastened with inserted anchor bolts, whose base ends are fixed to a floor board. CONSTITUTION:Steel plates 2 are held at intervals by distance holding materials 4 made from steel bars having threaded parts on both ends. To a sleeve 6 that is fitted and fixed to the lower part of the steel plates, anchor bolts 10, whose anchor plates 11 are buried into a reinforced concrete floor board 7, are inserted through and fastened. Then, concrete 3 is placed between the steel plates 2. Thereby, work can be executed easily. In addition, when any one of the wall balustrades 1 is damaged by an accident or the like, repair can be made easily by replacing with a new wall balustrade only by inserting the anchor bolts 10 through the sleeve 6 and by fastening them.
