摘要： PROBLEM TO BE SOLVED: To secure bending ability and an extending/contracting property, and moreover prevent the fall out of a pipe. SOLUTION: When the second pipe 14 is drawn out as much as fixed length from a through hole 42 according to the displacement of the ground due to an earthquake, engaging parts 62, 64 formed at the one and another ends of an arm 20 are locked at a sandwichedly holding member 18 and a joint body 16, and therefore the more drawing out of the second pipe 14 is prohibited. Since an arm inserting through hole 30 formed in the joint body 16 is formed in about conical shape, the arm 20 can be smoothly displaced according to the displacement of a core 24.

摘要： PURPOSE:To perform confirmation of a rubber ring in a proper position by a method wherein a hole extended through a receiving part is formed in the peripheral wall of a socket having a rubber receiving part. CONSTITUTION:A socket 14 is formed to the end part of a pipe body 12 and a rubber ring receiving part 16 is formed on the inner peripheral surface of the socket 14. A plurality of holes 18 extending through the rubber receiving part 16 are formed in a peripherally distributed state in the peripheral wall of the socket 14. A rubber ring 20 is mounted on the rubber ring receiving part 16. During joining, a pipe 22 to be joined is inserted in the socket 14 as, during joining, the mounting state of the rubber ring 20 is confirmed through the holes 18 through visual observation or by using a check gauge. This constitution improves workability since the mounting state of the rubber ring 20 is simply confirmed through the holes 18 through visual observation or by means of a check gauge.

摘要： PURPOSE:To generate a force for energizing a valve plate toward an opening direction at the time of closing for reducing a force necessary for opening the valve plate and ensuring the easy opening of the valve plate by forming separate space between a valve box and a valve bottom in close state for communication with space cellularized with a lid above the valve plate. CONSTITUTION:When a valve plate 20 is pushed down at the time of closing operation, fluid is drawn into the first space 28 through a gap generated between the valve plate 20 and a valve box secondary section 12b, thereby raising the internal pressure of the space 28. When the valve plate 20 is further pushed down, a seal member 26 comes in close contact with the internal projection 54 of the section 12b, thereby closing the first space 28 tightly. Concurrently, each of valve seats 22 and 24 comes in close contact with a valve box primary section 12a, thereby cellularizing the second space 56. This space 56 is communicated with the first space 28 via a hole 34 and a cavity 30 and, therefore, the internal pressure of both space 28 and 56 becomes equal. As a result, an upward force F acts on the valve plate 20. According to this construction, a force necessary for opening the valve plate 20 can be reduced and the valve plate 20 can be easily opened.

摘要： PROBLEM TO BE SOLVED: To increase the workability, by providing the first and second plates at the front and rear faces of the right and left forms respectively and bending the first plate after the second plate has been cut partly. SOLUTION: This corner form NO is constituted of the first plate 34 and the second plate 36 parallelly arranged at nearly the same distance with the thickness of the forms connected to each other at the right and left sides, partitions 38a, 38b connecting the plates 34, 36, and generally U-shaped receivers 40a, 40b. In this time, an elastic part 42 is formed on the plate 34 between the partitions 38a, 38b and a plurality of grooves 44 vertically extended are formed on the plate 36 between the partitions 38a, 38b. When forming a corner of a concrete wall, grooves 44 are cut to form the plate 36 having a width corresponding to the corner angle and the plate 34 is bent at a required angle at the elastic part 42. And then, the breadthwise ends of the right and left wall forms are inserted in the receiving parts 40a, 40b and respective forms are fixed and concrete is placed. In this way, a bend can be easily formed at an arbitrary angle.

摘要： PROBLEM TO BE SOLVED: To provide a connection member and connection structure for concrete forms in the vertical direction which can prevent water leak to the surface of the connection part and can offer an enhanced effectiveness in executing works and also enhanced appearance. SOLUTION: A flat plate 40 interposed between the bottom of the first concrete form 12 and the top of the second concrete form 14, and a sealing plate 42 is contacted with the concrete placed surface at the bottom of the first form 12 and the concrete placed surface at the top of the second form 14. A front surface plate 44 is installed in the position identical to the surface at the bottom of the first form 12 and the surface of the top of the second form 14. The surplus water, etc., of the concrete flowing down in a water leading layer 38a of the first form 12 passes through water permeative hole 46 furnished in the flat plate 40 and is led to water leading layer 38b of the second form 14.

摘要： PROBLEM TO BE SOLVED: To reduce the weight of a concrete placing form while keeping the strength and having fixed flame retardancy by sticking a flame retardant plate material onto the interior side surface of a form body formed of a plastic material heightened in ignition point by mixing a filler thereto. SOLUTION: A form body 16 formed of a first panel 20, a second panel 22, a rib 24, a block 28, a first fitting part 34 and a second fitting part 36 is extrusion molded by a plastic material increased in ignition point by mixing a flame retardant filler thereto. A heat insulating layer 26 is continuously formed out of an air layer formed of the first panel 20, the second panel 22 and the rib 24. A nonwoven fabric 30 is fixed as water permeable layer on the concrete wall 14 side surface of the hollow block 28, and the space surrounded by the block 28, the first panel 20 and the nonwoven fabric 30 forms a conduit 32. The ignition point of the form body 16 is increased, whereby a plate material 18 can be thinned to reduce the whole thickness and the weight, and since it is not required to provide a cavity between the form body 16 and the plate material 18, a sufficient strength can be ensured.

摘要： PROBLEM TO BE SOLVED: To provide a separation preventing structure for surely preventing pipe from slipping off. SOLUTION: In a connecting part 18 in which a spigot 12a of a pipe 12 is inserted into a socket 16 of a pipe 14, a first lock ring 22 is attached to the pipe 12, and a connecting end 34a of a wire 34 is connected to it. A ring- shaped second lock ring 36 is formed on the outer end side of the wire 34 along the outer periphery of the pipe 14 and arranged on a part in which the diameter of the socket 16 is decreased, and the diameter of the second lock ring 6 is specified by using a stopper 38. When force in extending direction is applied to the connecting part 18 for the pipes 12, 14 by the earth displacement by an earthquake, the first lock ring 22 is moved in the opposite side to the socket 16, the wire 34 is drawn, and the second lock ring 36 is locked on the part in which the diameter of the socket 16 is decreased. The spigot 12a of the pipe 12 is prevented from slipping off from the socket 16 of the pipe 14 in a state where the wire 34 is stretched. Therefore, the pipe can be reliably prevented from slipping off with a simple structure and easy mounting.

摘要： PROBLEM TO BE SOLVED: To provide a construction method of a concrete wall by which water leakage to the surface can be prevented and also provide a connecting and fixing member of the distance between the upper and lower parts of two waterproof forms in this new construction method. SOLUTION: After two waterproof forms 16, 18 have been vertically assembled by use of a connected member in which a first member 10 and a second member are assembled together, concrete is placed. The cement wash of concrete which has permeated through the permeable layer 36 of the upper waterproof form 18 and has flowed down along the water-conveyance layer 40b is accumulated in the space of the second member or discharged from a long hole. After the concrete has been cured, the second member is separated from the first member and the cement wash is removed and the water-conveyance passages 38a, 38b of the waterproof forms 16, 18 are secured. When a third member 14 as a fixing member is fitted to the connecting member of the waterproof forms 16, 18, the flowing-down water in the upper waterproof form 18 is led to the water-conveyance layer 40a of the lower waterproof form 16 by a throating part 62. In this way, the water leakage to the surface can be prevented in the vertical connecting part of two waterproof forms.
