摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a mold for a joint part and a form for a segment joint part, which can reduce the manufacturing cost of a segment form by manufacturing the segment joint form by concrete and by which a gap between joint parts of manufactured segment molded articles can be hardly formed. SOLUTION: According to this manufacturing method for a form for a segment joint part forming a joint part of a segment, a base having a form end plate part formed corresponding to the joint part of a formed segment is installed, and concrete is placed along the form end plate parts T1, T2 inside the form end plate parts T1, T2 of the master molds ML, MR of the base to form segment joint part molds AL, AR. Secondly, the segment joint part molds AL, AR are removed from the master molds ML, MR, and fixed at a space to both ends of the segment manufacturing molds AF1, BF1, CF1 to manufacture forms AF, BF, CF of each wing segment.

摘要： PROBLEM TO BE SOLVED: To provide an improved U-shaped channel block allowing smooth transmition of load to its side walls when a vehicle or the like runs on a lid plate, while preventing shaking of a lid plate, and allowing easy construction work to enable an accurate channel construction, and capable of securing a wide area for a flow passage and to provide a forming mold therefor. SOLUTION: In a U-shaped channel block 1, the outer surface 7 of each side wall 2, 2 from its upper side to its lower side is formed as one even vertical plane, and stepped faces 9 serving as lid locks are formed as inwardly and downwardly tilted planar or curved faces. A downwardly diverging flow-passage- enlarging tilted face 13 crossing each stepped face 9 at right or greater angles is formed on the inner surface of each side wall below the stepped face 9. Therefore, load from a lid plate is smoothly transmitted to the U-shaped channel block 1 without causing large local bending stress on the side wall 2. Since each stepped face 9 is formed to project inside of the side wall 2, problems regarding strength do not arise even if no outer flange is formed at the upper side of each side wall, and the outer surface of each side wall can be formed as one plane.

摘要： PROBLEM TO BE SOLVED: To easily manufacture a segment being a concrete structure which has jointing metal fittings provided at jointing end faces and has a smooth internal surface. SOLUTION: A form 21 is constituted of a bottom plate 22 forming the inner peripheral surface of a segment, circular-arc-shaped side plates 23 provided at the opposite side parts of the bottom plate 22 and end plates 24 connecting the opposite ends of the side plates 23. Each of jointing metal fitting retaining mechanisms 31 is constituted of a guide metal fitting 33 fixed to a base plate 32 of a bottom part outside the end plate 24, an engaging metal fitting 34 held by the guide metal fitting 33 and a ball screw 36 driven into a screw hole formed in the engaging metal fitting 34. A jointing metal fitting 3 is disposed at a notch part 44 of a projecting part 43 formed in the end plate 44 and the engaging metal fitting 34 is slid by rotating the ball screw 35 so that an engagement retaining part of the engaging metal fitting 34 be inserted into an engaging space of the jointing metal fitting 3 and engaged therewith. Thereby the jointing metal fitting 3 is made retained by the end plate 24.

摘要： PROBLEM TO BE SOLVED: To tightly adhere to an opening frame only by setting without performing shift correction by nut tightening or the like even in the case where a receiving frame can be set and a slight error such as shift occurs in a receiving part and the opening frame. SOLUTION: When an inverted U-shaped ditch block 100 having an opening for mounting a ditch cover on an upper part is formed, a receiving frame has a corner angle 2 integrated on concrete along the upper edge side of the ditch block and a longitudinal receiving part 4 for receiving the ditch cover by being hung from the inner edge of the corner angle 2. An end cover 7 covering the end face is provided on the longitudinal both end faces of the receiving part 4, and the upper end of the end plate 7 is set at a prescribed position by being pushed down to a substantially U-shaped inner frame molding the inside face of the ditch block.
