摘要： PROBLEM TO BE SOLVED: To prevent the blocking state from easily being released by easily blocking the drain pipe connection opening part of a common catch basin. SOLUTION: A blocking device for a common catch basin 11 has a blocking member 12 blocking the outflow opening part 4 of the common catch basin main body 1. It has a tightening receiving member 51 positioned to separately be opposed to the blocking member 12. A substantially annular tightening member 65 is disposed between the tightening receiving member 51 and the blocking member 12. A tightening mechanism 44 is operated and the tightening member 65 is tightened by a tool suitable for the rotation shaft 31 of the tightening mechanism 44. The tightening member 65 is pressed on the inner peripheral face of the outflow opening part 4, which is easily blocked. The tightening mechanism 44 cannot be operated by a tool un-suitable for the operation part 31 of the tightening mechanism 44, and the blocked state of the outflow opening part is simply released without notice.

摘要： PROBLEM TO BE SOLVED: To obtain a pipe body and a pope joint device which attain certain and easy connection without requiring piping members such as expandable/ contract able joint. SOLUTION: A fitting base 16 of a reception body 15 is fitted to a fitting part 11 prepared by widening an inner peripheral surface of a connection end of a joint body 10 rotatably in a circumferential direction. A stopping stepped portion 19 against which a pipe to be connected abuts is formed on the inner peripheral surface of the receiption body 15, while a half-cut reception port is formed through cutting in substantially semi-circular form to a leading end opening. The cut semi-circular portion of the reception part 20 is covered with an arcuate cover body 40. An arcuate engagement groove 23 is formed on an end face of the stopping stepped portion 19 perpendicular to an axial direction on the receiption part 20. An axially extending linear engagement projection 27 is formed along both side cutout edges 26 of the half-cut reception part 23. A semi-arcuate fitting edge 41 to be fitted to the arcuate engagement groove 23 is extended from a base end of the cover body 40.

摘要： PROBLEM TO BE SOLVED: To readily and inexpensively obtain a light-weight thermoplastic cement molding excellent in flame retardance, by blending a thermoplastic resin having a chlorine content equal to or more than a specific value with fixed amounts of a hydraulic cement and water and hardening the mixture without heating. SOLUTION: A thermoplastic resin having >=50wt.% water content in an amount of 100 pts.wt. is dispersed into 250-670 pts.wt. of a hydraulic cement. A polyvinyl chloride, a chlorinated polyvinyl chloride, a polyvinylidene chloride, etc., are suitable as the thermoplastic resin. Then the mixture is mixed with water in an amount corresponding to 10-60wt.% of the added hydraulic cement at a room temperature, packed into a molding frame and hardened without heating to give a thermoplastic cement molding. The obtained molding has intermediate properties between those of cement and thermoplastic resin and is properly useful for a building material, a material for engineering works, etc. The thermoplastic cement molding can be further mixed with glass fibers, metal fibers, a foaming agent, a pigment, a light stabilizer, etc., depending upon uses.

摘要： PROBLEM TO BE SOLVED: To prevent the direct applying of load and earth pressure from a road to an inlet body connected to a sewer installed to a slope way and a riser connected to the inlet body, to inspect the inlet body easily from a road surface and to mount an inlet readily even at a narrow place and a winding place. SOLUTION: An inflow port 22 is formed to one side section of an inlet body 21 while an outflow port 23 is formed to the other side section. The inflow port 22 and the outflow port 23 are communicated through an invert section 24. An end connection 31 for an inspection hole is projected towards an upper section on the top face of the inlet body 21. The end connection 31 for the inspection hole is inclined within an angular range of 5-30 deg. from the direction of 90 deg. on an axis tying the inflow port 22 and the outflow port 23 to the inflow 22 side. A riser 42 is connected to the end connection 31 for the inspection hole.

摘要： PROBLEM TO BE SOLVED: To provide a branch conector, which can securely and easily divide a branch pipe with a single operation. SOLUTION: A packing body 7 is tightly fitted in a base end of a locking part 12 of a fitting body 6. A sliding part 69 of a moving part 62 is inserted into a barrel part 11 of the fitting body 6 from a reinforcing part 31 side of a connector body 5 and engaged with a guide part 36 through an opening part 22 of the fitting body 6, and the moving body 61 is inserted into the opening part 22 of the fitting body 6. After inserting the moving part into a fixed body 8, a holding part 62 is screwed with a fitting recessed part 66 of the moving part 61 through an operation opening part 55 of the fixed body 8 so as to form a presser tool 9, and a branch joint main body 3 is integrally formed. A locking part 12 is inserted into the fitting opening part 2 and a locking claw part 20 of an elastic piece 19 is engaged with an edge of the fitting opening part 2. With the movement of the holding part 62 in the circumferential direction, the moving part 61 is moved so as to move the sliding part in the guide part 36. Since an engaging groove part 24 of the fitting body 6 and a guide projection 34 of the connector body 5 are engaged with each other freely to be slid in the axial direction, the moving force of the moving part 61 is converted to the moving force of the joint body 5 in the axial direction. A reinforcing part 31 is inserted in the locking part 12 so as to strongly lock the locking claw part 20.

摘要： PURPOSE: To prevent pulling-out or coming-off of a pipe body to be connected even when a high pull-out force is exerted on the pipe body to be connected due to a ground fluctuation occasioned by an earthquake. CONSTITUTION: A pair of holding bodies 12 approximately in an annular shape fitted in two end faces of an approximately cylindrical joint body 10 are provided. A pair of annular packings 16 fitted in the two end faces of the joint body 10 are nipped between the two end parts of the joint body 10 and an inner surface of each holding body 12. Lock protrusions 26 locked to a packing 16 are protruded and locked to outer peripheries of the tip parts, positioned facing each other, of a pair of pulling-out prevention cores 25 fitted in the respective joint bodies 10. By fastening the two holding bodies 12 against each other by fastening means 20 and 21, the packing 16 is forced into pressure contact with the outer peripheral surfaces of a pair of the pulling-out prevention cores 25. Pipe bodies 29 to be connected are connected in a fitted in state to the respective pulling-out prevention cores 25. This constitution brings the lock protrusions 26 of the pulling-out prevention cores 25 into contact with the respective holding bodies 12 through the packing 16 and prevents pulling-out of the pipe body 29 to be connected.

摘要： PURPOSE: To continuously obtain a lengthy thermoplastic cement formed material excellent in heat resistance, compressive strength and the like by extruding a specified forming material from an extruding die of a extruder immediately before passing it through a forming die to perform solidifying extrusion. CONSTITUTION: A forming material consisting of a thermoplastic cement composition is obtained by mixing 300-600 pts.wt. of hydraulic cement and/or non- hydraulic cement and 3-10 pts.wt. of hydrophilic cement with 100 pts.wt. of thermoplastic resin. The forming material is fed into a cylinder 2 of an extruder 1 through a hopper 5, and after while heated in heaters 4A-4D, it is melt and kneaded by an extruding screw 3, it is extruded in a specified shape from an extruding die 8 covered and formed over the whole inner surface with a skiddable material layer 14 of =50kg.f/10mm width tensile strength. Immediately after that, it is brought out to a forming die 9 covered and formed over the whole contact surface with the skiddable material layer 14 the same as the above and is subjected to solidifying extrusion, and then it is taken in by a take-in device 10.
