摘要： PURPOSE:To prevent the flotation of a liner resulting from the carbonization of an adhesive and the reduction of the effective cross section of a passage by connecting the core material of a reinforcing member and a lining main body by the connector piercing the peripheral wall of the lining main body and integrating the fluoroplastic of the reinforcing member and a fluoroplastic liner by welding. CONSTITUTION:A plurality of reinforcing members 3 are provided to the inner peripheral surface of a fluoroplastic liner 2 along the axial line of piping 1 over the total length of the liner 2 and each of them is formed by surrounding the periphery of a core material 4, for example, made of a steel plate. The core material 4 and the piping 1 are tightened by a stud bolt 7 being a connector and the fluoroplastic 5 of each reinforcing member 3 and the fluoroplastic liner 2 are welded (welded part 6b). As a result, the fluoroplastic liner 2 is reinforced by the reinforcing member 3 to prevent the flotation of the liner 2 and fixed strongly and easily. Since the reinforcing members 3 are arranged in parallel to the flow direction of the piping 1, by the presence of the reinforcing members, the effective cross area of a passage is not reduced and smooth flow is not obstructed.

摘要： PURPOSE:To embody the strip material capable of confirming the positional relation of a lock male part and a lock female part when a worker is situated in an existing pipe to line the inner peripheral surface of the existing pipe with the strip material by a sticking system and capable of rapidly and certainly performing lining work. CONSTITUTION:A fitting ridge 13 is provided to one side edge part in the lateral direction of the base plate 12 constituting a strip material 10 and a fitting recessed part 18 is provided to the other side edge part thereof. A hinge part 122 is provided to the base plate 12 at a position displaced to the inside of the lateral direction from the position of the fitting ridge 13 by a proper distance and the ridge 13 and the peripheral part are made bendable in the direction becoming the inner peripheral surface at a time of the formation of a pipe. In such a state that these parts are bent, the strip material 10 is rolled in a coil shape and the fitting ridge and the peripheral part thereof are folded back to be engaged with the adjacent fitting recessed part 18 of the strip material to form a pipe.

摘要： PURPOSE:To securely stop water in a connecting portion where a lining pipe for lining the inner circumferential surface of a sewer is connected to a branch pipe branched from an existing pipe. CONSTITUTION:The inner circumferential surface of a sever 40, from which a branch pipe 46 is branched, is lined by a spiral pipe 20. An opening 25 is formed in a portion of the spiral pipe 20, exposed to the branch pipe 46. The opening 25 is closed by a sealing tool 80 inserted into the sewer 40 and another sealing tool 46 inserted into the branch pipe 46. A spacer 75 fixed to a sealing tool 70 is located in the opening 25, thus forming a ring-like space in the opening 25. A sealant 90 is radially discharged from the spacer 75 to be filled in the ringlike space.

摘要： PURPOSE:To insert a spiral pipe into a drain pipe without breaking the spiral pipe and circulation water can be circulated in the spiral pipe. CONSTITUTION:A beltlike body 10 which is made into a spiral pipe lining a' drain pipe having beltlike base 12 and an expansion and contraction part 50 absorbing tension to a widthwise direction of the base 12 is formed by allowing the same to bend the base 12. An elastic member 51 positioning flush with the surface of the base 12 is arranged in the expansion and contraction part 50 under a compressed condition, when the beltlike body 10 is made into the spiral pipe, force to be applied to the widthwise direction of the base 12 is absorbed by the expansion and contraction part 50 and the elastic member 51 expands or contracts under a condition wherein the elastic member 51 is positioned flush with the inner crcumferential surface of the spiral pipe.

摘要： PURPOSE:To enhance the strength of a spiral pipe which is manufactured by winding a beltlike body around and prevent a water leak at an end part of the pipe. CONSTITUTION:When a beltlike body 10 is wound around, a reinforcing member 50 is fitted into a fitting recessed line 18 formed in one side fringe of a base 12 and a fitting projected line 13 is fitted into the reinforcing member 50. The reinforcing member 50 is pressure-contacted with the fitting projected line 13 within the fitting recessed line 18.

摘要： PURPOSE:To make the repairing of a pipe achievable from the inner surface side in a short time and accurately as well, by laminating X covers consisting of a thermoplastic resin impregnated sheet in piles in a central area on the outside of a sheetlike base free of widening motion so as to constitute a repairing coating body. CONSTITUTION:When a pipe 48 of a sewer or the like is repaired, first of all, in a state that a coating body consisting of a base 12 and a cover 14 is externally fitted in an expander 40, these elements are shifted up to the spot of a recess 50 formed in a repairing spot, in this pipe 48 via a rope 52. Next, an expansion part 44 of the expander 40 is inflated by compressed air to be fed via a nipple 46, and a coating body 10 is expanded, insomuch that both ends of the base 12 are slightly overlapped, and simultaneously the cover 14 consisting of a thermoplastic resing impregnated sheet is expanded in the radial direction in the state that both the ends are slightly lapped, thereby making the cover 14 and a partition member 16 go along an inner surface of the pipe 48. Subsequently, pressure in the expansion part 44 is released and the expander 40 is pulled out, while the base 12 is made to maintain its expanded form with its engagement with an engaging hole in an engaging part 28.

摘要： PURPOSE:To provide a ball collecting sheet which facilitates work of collecting golf balls mainly in a training field. CONSTITUTION:This sheet for collecting golf balls which has a fluorocarbon resin film formed on the surface of a thermoplastic or vulcanization-oriented synthetic resin sheet as base material. The synthetic resin sheet comprises vinyl chloride, polyethylene, polypropylene and EPDM. The ball collecting sheet is so low in friction force as to facilitate the collection of golf balls while improving the fading of color. This also enables the enhancing of weatherability and, moreover, minimizes the adhesion of dirts or the like to the surface. If adhering to the surface, dirts can be washed away easily by water.

摘要： PURPOSE:To maintain a heating device at a fixed temperature so as to manufacture a band wire of fixed quality by using an intermittently heated preheating device, and driving a band wire manufacturing device with a time difference kept between heating process and movement of wires. CONSTITUTION:A preheating device 5 is provided which serves as a preheating means for heating to a predetermined temperature a plurality of insulated core wires 3 arranged in parallel in their longitudinal direction and intermittently drawn by a drawer 3 end a control device 11 is provided which serves as an action controlling means for actuating the preheating device 5 before actuation of the drawer 3 is started, and lowering actuation of the preheating device 5 before actuation of the drawer 3 is stopped. Thus a band wire manufacturing device is so controlled that there is a time difference between movement and heating of each insulated core wire 1 in order for the preheating device 5 to heat each insulated core wire 1 at a fixed temperature. Thereby the insulated core wires 1 preheated at a fixed temperature are thermally fused to each other under fixed conditions by pressure contact method so as to make the quality of a band wire constant.
