摘要： PURPOSE:To prevent sandy ground from being liquefied, by embedding a box- formed unit into bearing ground to generate sliding resistance, and be draining excessive porewater on earthquake, through the small slot of the box-formed unit. CONSTITUTION:Flattened box-formed units 10 with a plurality of small slots arranged on both the side surfaces are connected together in a straight line via joints 12, and are embedded into ground on the periphery of a previously constructed harbour structure 4. Then, the box-formed units 10 are positioned in sandy ground 2 which could be liquefied on earthquake, and the upper ends are projected into water. As a result, sliding resistance to a sliding surface 6 is secured, and excessive porewater generated in the sandy ground 2 on the earthquake is discharged into the sea from the upper ends of the box-formed units 10, and so an area L' near the ground 2 can be also prevented from being liquefied.

摘要： PROBLEM TO BE SOLVED: To provide earthquake-resistant reinforcing structure, in which the site of a structure is utilized sufficiently and which is used for improving the earthquake-resistant performance of the structure including even a ground. SOLUTION: Steel sheet piles 5 are driven at a fixed distance so as to surround the building frame 1 of the structure. The top sections of the steel sheet piles 5 and the foundations 2 of the structure are connected and unified by concrete beams 6 horizontally projected from the structure building frame 1. The horizontal resistance force of a ground received by the whole surfaces of the steel sheet piles 5 brought into contact with the ground in the load working direction resists against the horizontal force. The maximum value of a ground reaction degree generated is inhibited by the foundation widening effect of the concrete beams 6, etc., projected from the building frame 1 to vertical force while the side movement of the ground is prevented by constraining the ground by the steel sheet piles 5, effective confining pressure is increased and ground strength is elevated. Vertical resistance force is burdened even by peripheral-surface frictional force among the concrete beams 6 protruded from the building frame 1 and the steel sheet piles 5 driven around the structure and the ground.

摘要： PURPOSE:To contrive an improvement in corrosion resistance, by a method wherein an iron-zinc alloy coating is formed by projecting particles obtained by cladding an iron-zinc alloy around nucleuses of iron or an iron alloy on at least a part of the surface of a steel material and a resin coating is formed by performing chromate treatment to the coating. CONSTITUTION:A coating layer 1 is formed by spraying strongly particles 2 obtained by cladding an iron-zinc alloy around nucleuses of microscopic iron or an iron alloy against the surface of a steel material 3 and moving the iron-zinc alloy on the external circumference of the particles to the surface of the steel material. Then water system chromate treatment is performed for which a water solution containing, for example, 0.1-50g/l of a chromic acid compound and 0.01-5g/l of sulfuric acid is used. Then a coating 5 such as urethane resin or tar epoxy resin or polyethylene resin is applied to the whole area or only a splash zone of the steel material. In addition, at the time of application of the coating to the same, it is preferable to form an appropriate substrate treatment layer 4 on a lower layer 1. It is good that in the case, for example, of the urethane resin, airless painting of urethane primer of an extent of 25mum is thickness is performed and that in the case, for example, of the polyethylene resin, polyethylene adhesive resin of an extent of 150mum in thickness is stuck through heating. In the case of the tar epoxy resin, the substrate treatment is unnecessary.

摘要： PROBLEM TO BE SOLVED: To effectively utilize a piece of land, shorten a construction period of time and to reduce a construction cost in the construction of an underground structure. SOLUTION: A steel sheet pipe 1 used for earth retaining wall and bearing wheel in a basement is driven to the limit of a site boundary. The inside surrounded by a steel sheet pile continuous wall is excavated to form a space for the basement. The upper end of the steel sheet pile 1 is utilized as a continuous footing, shape steels 4 and 5 as foundation or floor beam are rigidly connected thereon, and a portal frame skeleton for part of the basement 10 is formed. A ground building is borne on a directly upper position of the steel sheet pile 1 through the shape steels 4 and 5. As the steel sheet pile 1, joint shapes of both ends are bilateral asymmetry, and cross sectional shapes are arranged in the same direction to use the asymmetrical U-shape steel sheet pile capable of being connected on a straight line.

摘要： PURPOSE:To permit a structure to be directly installed on undulatory seabed by a method in which many hollow globules are packed into a plurality of compartments provided in the bottom of the structure. CONSTITUTION:Partition walls 11 are formed on the bottom to form a plurality of compartments 12 for a structure 1, e.g, caisson, etc. The structure 1 is towed to a construction site by a barge 2, and many hollow globules having a smaller specific gravity than 1 has been filled into the compartments beforehand. Sea water is charged into the structure 1 to settle it onto seabed. When the structure 1 is landed on the seabed, the globules 3 are displaced, deformed, or broken according to the undulatory surface of the seabed and closely fitted without gap to the configuration of the seabed. The structure 1 can thus be directly installed on the undulatory seabed.

摘要： PURPOSE:To prevent sandy ground from being liquefied, by embedding a hollow pile into bearing ground to generate sliding resistance, and by discharging excessive porewater on earthquake, through the small slots of the hollow pile. CONSTITUTION:A hollow pile 10 with a plurality of small slots arranged on the intermediate section 12 is embedded into bearing ground 1 at the sea bottom in front of a previously constructed sheet pile quaywall 40. Then, the head section of the pile 10 is positioned on the level of the upper surface of the quaywall 40, and the intermediate section 12 with the small slots of the pile 10 is positioned in sandy ground 2 which could be liquefied on earthquake. After that, the head section and the underwater section of the pile 10 are rigidly connected to the quaywall 40 with a connecting member 13. As a result, sliding resistance to a sliding surface 6 is secured, and excessive porewater generated in the sandy ground 2 on the earthquake is discharged into the sea from the pile 10, and so an area L' near the ground 2 can be also prevented from being liquefied.

摘要： PURPOSE:To prevent a beam member from contamination caused by waste water containing a mortar component and improve the economics in the case of depositing floor concrete on deck plates spread on the beam members. CONSTITUTION:A metallic foil tape 1 such as an aluminum foil is stuck on the upper face of a upper flange of a H-steel 4 serving as a beam member, and a deck plate 5 is spread on the tape 1, and floor concrete 7 is deposited on the deck plate 5. The metallic foil tape 1 is stuck so as to jut out sideward from the end of the upper flange to prevent waste water which is oozed out from a gap by depositing the concrete 7 and contains mortar component from flowing down from the edge end of the metallic foil tape 1 to contaminate the H-steel 4. After curing the concrete 7, the jutting part of the metallic foil tape 1 is cut off by a cutter or the like as occasion demands.

摘要： PURPOSE:To obtain a steel pipe concrete pole which is economical and excellent in fire resistance. CONSTITUTION:A steel pipe concrete pole is constituted by an outer steel pipe 1, an inner steel pipe 2 and a filling concrete 8 into the inner steel pipe 2, and a hollow part 3 is formed between the outer steel pipe 1 and the inner steel pipe 2. As the inner steel pipe 2 is surrounded by the outer steel pipe 1 and the hollow part 3, heat caused by fire is transmitted to the inner steel pipe 2 only through radiation from the inner face of the outer steel pipe 1 and convective heat transfer by air in the hollow part 3, and temperature rise is delayed compared to the outer steel pipe 1. Also, by filling the inner steel pipe 2 with the concrete 8, heat capacity of the steel pipe concrete pole gets larger and the temperature rise is slower than when the pipe 2 is not filled.
