摘要： PROBLEM TO BE SOLVED: To provide a reinforcing structure of an existing construction and a reinforcing method capable of improving the anchorage of a fiber reinforcing sheet to enhance the reinforcing strength and reducing the construction period of the reinforcing work for the existing construction. SOLUTION: An adhesive 16 is applied on the surface of an existing construction 10 to be reinforced and fiber reinforcing sheets 12 are stuck thereon. A plurality of anchor plates 14 attached at every distance to fix the fiber reinforcing sheets 12 to the existing construction 10 are pressed to fix them to the construction from above the fiber reinforcing sheets 12 before the adhesive 16 is hardened to extrude the adhesive 16 from between the anchor plates 14 in between the fiber reinforcing sheets 12 and the existing construction 10 and put it in between the sheet 12 and the existing construction 10.

摘要： PURPOSE:To obtain a water shielded wall of high reliability by mixing calcium hydroxide in cement and making a column array wall in V-shaped cross section in which an earth lowest part of the column array wall is crossed and contacted so that the earth lowest end part is shielded vertically. CONSTITUTION:Since the lower part of the bottom part of a concrete closed vessel 3 is shielded in the earth, a water shielded wall 9 is constructed of an inclined column array wall 10 at which the lower end from the position separated from the two facing sides of a surface quadrangle vessel 3 respectively a little is inclined and solidified. The other two sides are constructed of a vertical column array wall vertically solidified to come in contact with each end part of the wall 10. The end of the wall 10 is crossed in the vertical direction of a center line of the vessel 3, and an inverted gabled water shielded wall 9 is formed of the wall 10 and a vertical column array wall. The wall 10 and the vertical column array wall are soil cement water shielded walls mixed and agitated with sediment by the use of cement milk and calcium hydroxide. A water collecting part 12 and a storage pump are provided on the bottom of the water shielded wall 9 and the water level of the water collecting part 12 is lower than that of an outside protective zone 13.

摘要： PROBLEM TO BE SOLVED: To aseismatically reinforce an existing concrete column by bonding a plurality of steel sheets over an outer peripheral surface of the column which are coated with a resin adhesive so as to surround the concrete column therearound with the steel sheets, and by bonding carbon fiber sheets to the steel sheets so that the carbon sheets bridge joints between the steel sheets. SOLUTION: A resin adhesive 2 is coated over the outer surface of an existing concrete column 1 at which the existing finishing material is exposed. A pair or U-like cross-sectional shape steel sheets 3 having an internal size slightly larger than the external size of the concrete column 1 are pressed against the outer surface of the concrete column 1, and are then temporarily fixed by a press jig 4. Thereafter, a resin adhesive 2 is applied to the external surface of the steel sheet 3, bridging joints between the steel sheets 3, and then carbon fiber sheets 5 are applied and secured thereto, extending vertically. Further, the resin adhesive 2 is applied over the applied carbon fiber sheets 5 so as to enhance the strength of the fibers of the sheets 5. After the resin adhesive 2 cures, the press jig 4 is removed, that is, the aseismatically reinforcing work is completed.

摘要： PROBLEM TO BE SOLVED: To improve the aseismatic strength by bonding an FRP sheet with an adhesive, and also, extending the sheet to a pole or a beam, and fixing the extension with a metal fitting, when reinforcing the concrete wall surrounded by poles or beams with an FRP sheet. SOLUTION: An FRP sheet 3, which is reinforced with carbon fibers, etc., after execution of proper foundation processing or primer processing, is arranged being extended as far as the thick part of a beam 2 or a pole, at the surface of a concrete wall 1 or said beam 2 and it is bonded by an adhesive. In this case, the end of the FRP sheet 3 is fixed by an anchor bolt 4 through a press metal fitting 5 consisting of a steel plate or the like. For the press metal fitting 5, an angle steel or a channel steel can be used, and besides the middle part of the FRP sheet 3 can be fixed similar to the end. The shearing force working on the section of a wall 1 is scattered effectively through the FRP sheet 3. Hereby, the aseismatic strength can be improved sharply.

摘要： PROBLEM TO BE SOLVED: To prevent the exfoliation of a sheet by bonding an FRP sheet, and applying a press metal fitting to a proper place, and fixing the press metal fitting with a bolt, etc., when sticking the FRP sheet to a concrete wall or the like for reinforcement. SOLUTION: An FRP sheet 3, which is reinforced with carbon fibers, etc., after execution of proper foundation treatment or primer treatment, is arranged as far as the reentrant angle part on the boundary with a pole 2, at the surface of a concrete wall 1, and it is bonded by an adhesive. In this case, a press metal fitting 5 is fitted to the FRP sheet 3, and it is fastened with a fixing metal fitting 4 consisting of a bolt or the like. Moreover, the press metal fitting can be made of an angle steel, and attached to the pole 2 by an anchor bolt or the like. This reinforcing method can also be applied to a pole or a beam. This is so arranged that the FRP sheet 3 does not peel off the concrete body 1, and that the reinforcement effect does not drop. Hereby, the reinforcement effect can be improved.
