摘要： PROBLEM TO BE SOLVED: To provide a method for suppressing cracking of a concrete structure caused by change in ambient temperature, the concrete structure being susceptible to cracking, and to provide a method for particularly preventing cracking of the concrete structure caused by change in the ambient temperature after injection of a filler, by using the characteristics of the filler once injected into a gap in the concrete structure. SOLUTION: There is provided a method for suppressing cracking of the concrete structure, according to which the filler formed of a room temperature curing resin composite is injected into the gap in the concrete structure. Herein, the employed room temperature curing resin composite should have an elongation percentage of 200% or more when cured, and adhesive strength to a dry mortar cured body of 5 N/mm 2 or less. Thus, the resin composite injected into a hardened layer of the stratum functions to release thermal cracking stress generated at the gap or in the vicinity of the gap. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To curtail a construction period and to improve quality by simplifying the shape of a pipe constituent member, obviating a joiner, facilitating the joining between spirally wound pipe constituent members, securing strength and water tightness sufficiently by simple structure, obviating a spacer for packing grout, support for preventing the bend of a pipe, water change, and others, reducing members, and preventing a grout packing process from being complex. SOLUTION: Ribs 6b are erected on both sides in the length direction of a main body part, a belt-shaped body 6 in which a recessed part is formed between the ribs 6b and a cylindrical body 7 which is housed in the recessed part and installed in the clearance between it and an existing pipe are combined, the belt-shaped bodies 6 form a joining strip 8a for forming a spiral pipe body by joining the bodies 6 to each other on the outsides of ribs of the right and left side fringes and a groove strip 8b. The cylindrical body 7 is formed from a material which allows the water of a filler packed in the inside to pass but does not allow solids to pass and is swelled by internal pressurization.

摘要： PURPOSE:To eliminate the need for a high scaffolding for the construction of an upper floor board and excavate a road space with safety and eliminate the need for a temporary earth retaining work on a large scale and hence prevent an excessive increase in a construction cost and period as well. CONSTITUTION:Prior to the construction of a box 7 which is substantially trapezoidal or rectangular in shape as a road space, the space is cut at a stable slope up to the area equivalent to an upper floor board 8 of the trapezoidal or rectangular box 7. A side wall 9 is constructed continuously from the cut down position outwardly on the slant. Furthermore, the upper floor board 8 which connects the side walls 9 is constructed. In this fashion, at the stage when the side walls 9 and the upper floor boards 8 are finished in this manner, the road space is excavated from the end of the space while subgrade concrete is cast simultaneously.

摘要： PROBLEM TO BE SOLVED: To provide a tendon anchorage device capable of preventing non- corrosion proofing of a tendon in a part around a mounting section after it is mounted to the tendon. SOLUTION: In the tendon insertion hole 1b of an anchorage device 1, an uncovered part 3b of a tendon 3 is involved in a frictional resistance increasing insert 4 and, at the same time, part of a corrosion proofing treatment sheath 2 is involved in an insert unloaded part 1d to which the frictional resistance increasing insert 4 is not loaded. The sheath 2 is also involved in the insert unloaded part 1d with low biding work ratio, and even if the anchorage device 1 is mounted to the tendon 3 by means of binding work, the sheath 2 is not damaged in the anchorage device 1. Part of the corrosion proofing treatment section (sheath 2) together with the uncovered part 3b of the tendon 3 can be also involved inside the anchorage device 1, and when the anchorage device is mounted to the tendon 3, the sheath 2 is to prevented that it is eliminated to form the uncovered part 3b around the mounting section.
