摘要： PROBLEM TO BE SOLVED: To simply correspond to the displacement of the ground in the both directions of expansion and contraction. SOLUTION: At the time of execution, a spigot 17 is positioned by a stopper 24 formed at about intermediate position between a rubber ring groove 20a and an enlarged diameter start end 22. When pushing-in force more than allowable value acts on the spigot 17 on account of the displacement due to an earthquake of the ground, the spigot 17 bends the stopper 24 and gets over it to move toward the enlarged diameter start end 22. The displacement of the ground is thereby absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a separator hole collar capable of contributing to cost reduction and saving preparation such as troublesome classification. SOLUTION: A separator hole collar 10 has a guide 20 mounted in a separator hole 14 formed in a hollow formwork 12 and provided with a smooth inner periphery to guide a separator. The guide 20 has a tapered part 20b to be freely reduced in diameter to the vertical direction of the hollow formwork 12 and a contact part to seal the small-diameter end of the tapered part 20b. When the separator hole collar 10 is mounted in the separator hole 14, the tapered part 20b is reduced in diameter corresponding to the inner diameter of the separator hole 14. Because the separator hole collar 10 can be mounted in various diameters of separator holes 14, there is no need for preparing several types in classes, resulting in cost reduction.

摘要： PROBLEM TO BE SOLVED: To provide an extended formwork and a concrete wall structure using such extended formwork capable of firmly preventing water from entering into an electric wiring embedded box without being affected by working ability. SOLUTION: This concrete wall structure has a through hole 26 formed in the position of a concrete formwork 12 corresponding to the position of an embedded box 16 embedded in a concrete wall 14 placed by the concrete formwork 12. An joint frame 10 is arranged inside the through hole 26 so as to abut on the front of the embedded box 16 and a wall outlet parts 30 and the like are furnished. Thus when surplus water inside the concrete wall 14 flows down inside a water conveying layer 12a of the hollow formwork 12 and reaches the upper part of the joint frame 10, the surplus water flows along the outside circumference of the hollow formwork body 18 and is guided to the lower part. At this time, the water flowing along the outside circumference of the hollow formwark body 18 is intercepted by two ribs 18c and flows down between the ribs 18c.

摘要： PROBLEM TO BE SOLVED: To bend forms at an arbitrary angle and execute the forms by using the forms with two panels mutually arranged in parallel, cutting a part of one panel and bending the other panel. SOLUTION: A first panel 16 and a second panel 18 are disposed mutually in parallel at a regular interval and connected by a plurality of ribs 20, and air layers continuing in the horizontal direction are formed and used as heat- insulating layers 22. A plurality of hollow blocks 24 are formed to surfaces on the concrete wall 14 side of the first panel 16, and nonwoven fabrics 26 are fixed onto the surfaces on the wall 24 side and headraces 28 are formed. When a surface on the room side of wall structure 10 is formed in a flat surface, the forms 12 are employed as they are. When the surface on the room side of wall structure 10 is formed in a curved surface, the second panel 18 and the nonwoven fabrics 26 are cut at required places, and the first panel 16 is bent at a fixed angle and executed. Accordingly, the place of the bending of the forms 12 and the angle of bending, etc., can be adjusted arbitrarily, and the degree of freedom of a design can be improved.

摘要： PROBLEM TO BE SOLVED: To easily and surely connect a separation preventing joint and a pipe. SOLUTION: A pipe 12 is inserted to a prescribed position in a socket 14. By a T bolt 26 and nut 34, a joint main unit 16 and a press ring 28 are connected. Successively, a bolt 46 is screwed to an insertion hole 44 of the press ring 28. In a ring storage part 40 of the press ring 28, a separation preventing ring 38 setting its internal diameter larger than an external diameter of the pipe 12 is stored. This separation preventing ring 38 is pressed in a diametrically contracting direction by the bolt 46, to be movably fixed to a peripheral surface of the pipe 12. That is, only unless the bolt 46 is screwed, the joint main unit 16 and the press ring 28 are moved in the axial center direction of the pipe 12, a separation preventing joint 10 can be mounted in a desired position.

摘要： PROBLEM TO BE SOLVED: To always compensate for the expansion or contraction of a pipe. SOLUTION: On the outer periphery of a pipe 16 inserted into a rubber ring socket 14, a stopper 10 is elastically mounted at a predetermined spaced position from the tip end. When the pipe 16 is inserted into the rubber ring socket 14 by a predetermined length, the tip end of the rubber ring socket 14 is engaged with the stopper 10 to restrict the movement of the pipe 16 in its axis 20 direction. A desired expansion or contraction margin L is thus always ensured conforming to the design.

摘要： PROBLEM TO BE SOLVED: To improve execution property by continuously fitting a smooth inner peripheral face to the separator hole of a form in the thickness direction of the hollow form, pressing a contact piece arranged on the surface side of the form with a separator tip, and removing it from the separator hole to be repeatedly used. SOLUTION: When hollow forms 12 are arranged at constant intervals on an earth retaining wall, the inner peripheral face of the hole 10a of a separator hole collar 10 fitted to the form 12 is smoothly installed. When a separator 18 is arranged obliquely to the vertical direction of the earth retaining wall, the hooking of a rib on the heat insulating layer 12a and water guide layer 12b of the form 12 is excluded, and the inner peripheral face of the hole 10 a is smoothly inserted. When a support material and a separator part 18b are removed after concrete is placed, multiple holes 10a are formed on the principal plane of the heat insulating layer 12a of the form 12. Plugs having the outer diameter slightly larger than the diameter of the holes 10a and the length of about the thickness of the form 12 are inserted into the holes 10a. The collar 10 is expanded in diameter, the watertightness of the portion of a separator hole 14 formed on the form 12 is improved, and the leak of excess water to the surface side from concrete is prevented.

摘要： PURPOSE:To save the space and simplify the fitting construction by forming circumferential grooves in a short pipe with one end inner diameter thereof set to receive the outer periphery of a pipe spigot and the other end inner diameter thereof set to receive the opening end outer periphery of a pipe socket, and inserting C-type rings, provided with the inner peripheral faces thereof formed into slip preventing faces and the outer peripheral faces thereof formed into slide faces, into both grooves. CONSTITUTION:The inner diameter of one end 11A is set to the inner diameter d1 for receiving the outer periphery of a pipe spigot A, and the inner diameter of the other end 11B is set to the inner diameter d2 for receiving the outer periphery of a pipe socket B. At the opening ends of a short pipe 11 of different inner diameters d1, d2, circumferential grooves 14A, 14B are formed in such a way that the bottom faces 13A, 13B are tapered toward the pipe end direction (an arrow mark X). Inside the circumferential grooves 14A, 14B, C-type rings 15A, 15B are inserted in such a way that the inner peripheral faces thereof are formed into slip preventing faces that can be brought into contact with the outer faces of the pipe spigot A and the pipe socket B and that the outer peripheral faces thereof are formed slide faces that can be brought into contact with the bottom faces 13A, 13B of the circumferential grooves 14A, 14B. This results in making the whole structure compact, facilitating fitting work and preventing slip-off by the C-type rings.
