摘要： PROBLEM TO BE SOLVED: To conduct connection with a pile at the lower end of a sleeve, and to support large load without lengthening the fixing length of the sleeve and the pile. SOLUTION: When the lower end section of a sleeve 1 and a pile 4 in the jacket structure are coupled, ribs 12 and projections 14 are joined mutually on an inner circumferential surface on the sleeve 1 side and an outer circumferential surface on the pile 4 side and the sleeve 1 and the pile 4 are connected, and the load of the jacket structure is transmitted to the pile. Connection with the pile 4 is conducted at the lower end of the sleeve 1, and large load is supported without lengthening the fixing length of the sleeve 1 and the pile 4.

摘要： PROBLEM TO BE SOLVED: To absorb an earthquake energy prior to breakdown of a pillar main member, prevent breakdown or damage of the main member, and thereby facilitate replacement of a vibration-mitigating member by forming a part of a vibration-mitigating member connecting upper and lower parts of the column of a pier with a steel material having a lower yield point than those of other parts. SOLUTION: A vibration mitigating member consisting of a damper member 9 and rod member 10 is connected to a bracket 8 attached to the upper and lower peripheries of the column part 2 of a pier. The rod member 10 is manufactured of a belt-like steel plate having the same strength as the main member of the column member 2, and the damper 9 is manufactured of a steel plate having a lower yield point and larger elongation than that of the main member of the rod member 10 and the column part 2, then both of the upper and lower ends are made replaceable relative to the bracket 8 and the rod member 10. When the pier is deformed by horizontal force at an earthquake, the damper 9 with the lower yield strength than that of the rod member 10 yields so that an earthquake energy can be absorbed prior to yield of the main member of the column part 2, as a result, yield and damage of the main member of the pillar part 2 can be prevented.

摘要： PURPOSE:To fulfill an inexpensive and anti-corrosive effect for a long time, by arranging reinforcing bars between protruding reinforcing steel ribs on a steel plate constituting the body and by charging concrete in the space formed by this construction. CONSTITUTION:Reinforcing steel ribs 5 are implanted integrally at a plurality of places on the side steel plates 4 constituting the body of a floating wave- dissipation dam. Next, reinforcing bars are arranged between the reinforcing steel ribs 5. And then concrete 1 is poured in the space constituted thereby to cover the outer face of the steel side plates 4. In this way, the steel plate faces are protected from sea-water to fulfill an anti-corrosive effect for a long period and repeated reuse becomes possible after durable years.

摘要： PURPOSE:To reduce the construction period in field, to improve the appearance and to facilitate future repair by fitting the lower end portion of a previously manufactured precast steel plate concrete balustrade block between a pair of angle members anchored on a floor plate. CONSTITUTION:A balustrade block A formed by placing concrete between a pair of steel plates 2, 2 held at a designated space through a spacer member, with the lower end space 3 left undone to be filled up therewith is previously manufactured in a factory. The balustrade block A is built up between a pair of confronting angle members 8, 8, the lower end portions of which are anchored on a floor plate B through anchor reinforcements 10, and after the height adjustment is made through a screw jack C or the like and fixed by bolts 17 or the like, concrete mortar is poured in the space 3 through a mortar filling port 18 to integrally join the block on the floor plate B. Thus, the field execution range is remarkably reduced to shorten the construction period in field.

摘要： PROBLEM TO BE SOLVED: To improve water sealing performance, and to prevent leakage of grout by differencing the length of one end part and the length of the other end part running in the peripheral direction of an elastic water sealable annular plate-like seal material in a seal installed in the joining part between a cylindrical leg and a steel pipe line inserted into the leg. SOLUTION: A brush type seal 11 installed in the joining part between a cylindrical leg 5 and a steel pipe pile 6 inserted into the leg 5, is formed as a structure by combining spring steel, a wire brush and a stainless steel wire net, and is composed of a cylindrical upper member running along the inner peripheral surface of the leg 5 and an almost funnel-shaped lower member wound along the peripheral surface of the steel pipe pile 6 by extending downward from the lower end of this upper member. Here, the length of one end part and the length of the other end part running in the peripheral direction of a seal material are made different. Thus, even if dislocation is caused between the steel pipe pile 6 and the leg 5, a seal can instantly cope with it by resiliency of the brush type seal 11 to improve water sealing performance in the joining part as well as to prevent leakage of grout 9 injected into the joining part.

摘要： PROBLEM TO BE SOLVED: To make a bank constructible at any time by a method wherein a movable structural body at the inside of a housing part is set afloat in a liquid entering into the housing part, and the movable structural body is made to project beyond the upper opening of the housing part. SOLUTION: A floating lift is constructed with a movable structural body 4 housed, capable of rising and falling, at the inside of a housing part 3 that is buried at the lower part of the ground G. While the structural body 4 is equipped with a lower floating structure 4a and an upper structure 4b, sealing surfaces 4c and 3c are provided respectively at the upper inclined wall of the floating structure 4a and the peripheral underside at the upper opening 3a of the housing part 3. When the structural body 4 is used for instance as a bank, buoyancy is given to the floating structure 4a with the inside of the housing part 3 filled with water, and the upper structure 4b is made to project upward beyond the upper opening 3a. On an occasion of nonuse, the structural body 4 is lowered with water 5 inside the housing part 3 discharged, making the structural body not obstructive, and thereby a bank or a partition wall at the site for an exhibition or the like can be formed simply. Furthermore, sufficient safety can be ensured as sealing is made automatically when used as a bank.

摘要： PROBLEM TO BE SOLVED: To improve earthquake resistance by supporting a pier, in which concrete is placed onto the inner circumferential surface of a grooved steel pipe onto a footing through a cryogenic yield-point steel plate. SOLUTION: Concrete 2 is placed onto the inner circumferential surface of a grooved steel pipe 1, and a pier 3 having double steel shell structure is fored. Cryogenic yield-point steel plates 4 are arranged onto the outer circumference of the base section of the pier 3 in a rib shape, and the pier 3 is supported to an annular fixing section 6 disposed in upright on the top face of a footing 5 through the steel plates 4. Stress is transmitted to the footing 5 by the fixing section 6 through the steel plates 4 in horizontal force applied to the pier 3 by an earthquake. The steel plates 4 are yielded prior to the pier 3 consisting of common steel and absorb the energy of the earthquake while filling the role of a damper and the ductility of the pier 3 is improved. Accordingly, earthquake resistance can be enhanced, the pier 3 can be reused simply only by replacing the steel plate 4 as a damaged section after an earthquake, the composite ductility of steel and concrete is elevated and the force of inertia of the pier 3 at the time of the earthquake can be lowered without increasing the weight of the pier 3.
