摘要： PROBLEM TO BE SOLVED: To provide a repair and reinforcing method for the surface of a structure capable of economically lengthening the years of durability of the surface for various deteriorated concrete infrastructures by utilizing new materials. SOLUTION: A predetermined surface of the surface layer of a surface to be repaired of a concrete structure consisting of a plane or curved surface is covered, a surface coming into contact with the concrete structure is tightly adhered to a flexible form 1 having grooves formed to a grid pattern or a pattern of meshes of a net, and a two-liquid type reaction type hardening resin is injected to the surface to be repaired from a filling hole 3A made in the form 1 in this repair and reinforcing method for the structural surface. At this time, a negative pressure is given to the surface to be repaired, and the two-liquid reaction type hardening resin is sucked and filled to the surface to be repaired in a state of a negative pressure given to the surface to be repaired. Moreover to the surface to be repaired, a grid-shaped or mesh-shaped projected stripes made of the two-liquid reaction type hardening resin alone or with a compound member of a tensile reinforcing material are formed. In forming this projected stripes, the two-liquid reaction type hardening resin is injected and continuously and at the same time to the inside having cracks as structural defects thereby forming a reinforcing shape with strong anchors as one united body.

摘要： PURPOSE: To make it possible to use easily lower end reinforcements as through reinforcing bars. CONSTITUTION: A cross section-U-shaped notched part 2, whose length exceeds the width of a post to which the main body 1 is connected, is installed to the lower part of a beam main body 1 in its longitudinal direction. The terminal of a sheath 3 for lower end main reinforcement insertion is opened on both ends of the notched part 2. The lower end main reinforcements inserted and incorporated in the beam are laterally moved by way of the sheath of a post and connected to the adjacent lower end main reinforcements at the notched part 2. Across section-U-shaped form, which is low in height, is installed to the notched part 2. Concrete is adapted to flow in from a clearance between the upper end of the side wall and the main body 1, thereby forming an I-shaped cross section for the beam in this area.

摘要： PURPOSE:To make it possible to introduce easily prestresses to connect precast concrete columns in a plurality of storeys. CONSTITUTION:Precast concrete columns 1 and 2 of first and second floors are formed in a cylindrical hollow body, prestress is introduced with PC steel materials 6 and 12 arranged to hollow sections 5 and 11, and the precast concrete columns 1 and 2 are connected together as a unit. According to the constitution, weight of the precast concrete column is decreased, so that conveyance and lifting work of the precast concret column is carried out easily. It is not necessary to bury a sheath in the precast concrete column, and work can be easily carried out. Formwork and reinforcing bar placer are not required in the field.

摘要： PURPOSE:To enable binding a column with beam with no thickened section formed at the ends of the beams in pre-cast assembly works. CONSTITUTION:PC steel members 11 penetrating through a column 10 are bound with and fixed onto the vertical wall surface of an opening 2 formed at the intermediate position of the back of the end of each beam 1, so that the column 10 is thereby bound with each beam 1. Each beam 1 is respectively provided with PC steel insertion holes 4 between the opening 2 and each end face other than the aforesaid opening 2, and is also provided with each duct hole 5 which is aligned with each PC steel member insertion hole 4, between both holes at the end sections of each beam. By this constitution, the column can be bound with the beams with no thickened section formed, and this method is advantageous in the toughness design of a building.

摘要： PURPOSE:To improve stability for resistance force against waves and for tides or the like by arranging a pair of cables in almost X shape between a guide member in a float structure side and a fixed member in a water bottom side part and suspending a weight in a free end through the guide member of the cable. CONSTITUTION:A plurality of floating cases 2, formed as a box-shaped single product of hexahedron floated on the surface of water, are carried to a facilities spot, and by successively connecting the floating cases in the spot, a pier (not shown) and a mooring blade 4 are built. The pier is vertically movably moored through an engaging member to a pile driven into the bottom of the sea, on the other hand, the mooring blade 4, connected to a side part of this pier and utilized for mooring of a small ship and its departure and arrival, is moored to the water bottom part by a mooring device 10. Here the mooring device 10 is constituted of a guide member 11 provided in a reverse side of the floating case 2 by holding a predetermined space, fixed member 12 set up in the water bottom part, two cables 13 arranged almost in X shape between these members 11, 12, weight 14 suspended to a free end of this cable 13 and a float unit 15 mounted to the reverse side of the floating case 2.
