[Detailed description of the invention] (Field of industrial application) This invention relates to a terminal device that is attached to the end of a separator used in concrete construction. (Prior art) Conventional terminal devices for separators of this type include:
There is an idea described in Utility Model Publication No. 45-29412. (Problems to be solved by the invention) The conventional separator terminal device described above consists of a synthetic resin formwork piece that is screwed onto the male screw at the end of the separator and left inside the concrete wall, and (1) Due to shrinkage during concrete hardening, etc., the gap between the concrete wall and the formwork piece may deteriorate over time. There will be a gap between. (2) The formwork support piece and the stopper do not fit completely and there is a gap between them. (3) The cover thickness between the concrete wall and the separator is small and constant. Therefore, the above gap becomes a water supply, and rainwater, etc. infiltrates from the wall surface into the gap between the concrete wall and the separator through the gap between the concrete wall and the formwork support, and between the formwork support and the plug. and rust the separator. As a result, (a) the durability of the structure decreases; (b) Water containing rust flows onto the wall surface, damaging the aesthetic appearance of the wall surface. There are problems with these points. (Means for solving the problem) Therefore, this invention can arbitrarily increase or decrease the cover thickness between the wall surface and the separator, and furthermore, it is possible to prevent rainwater from flowing from the wall surface to the separator part inside the concrete wall. In order to solve the above problems by preventing the penetration of A terminal main body 7 in which a female screw tube 4 made of metal or the like is embedded, and a recess 6 with a diameter larger than the screw hole of the female screw tube 4 and a female screw 5 on the circumferential surface is formed at the other end. A male screw 9 is provided at one end of the synthetic resin cylindrical body 8 to be screwed into the recess 6 and the female screw 5 of the terminal body 7 , and a male screw 9 with a diameter larger than that of the hole is provided at the other end of the hole on the circumferential surface. An additional terminal 12 having a recess 11 provided with a female thread 10, and the terminal body 7
or a water-expandable water-stop ring 13 that fits around the outer periphery of the cylindrical bodies 1 and 8 of the additional terminal 12 , and a water-expandable water-stop ring that fits into the recesses 6 and 11 of the terminal body 7 or the additional terminal 12 ; 14, and a male screw plug 15 screwed into the female screws 5, 10 of the recess 6 or 11. (Example) To explain the structure of an embodiment of this invention shown in the drawings, A is a concrete wall, 2 is a separator, male screws 3 are provided at both ends,
A stopper 16 is formed at the base end of the male thread 3. 7 is a terminal body, in which a female threaded tube 4 made of metal or the like is buried in one side of the hole of the synthetic resin cylinder 1, a collar 17 is provided on the outside of the other end, and a female threaded tube is provided on the inside. A terminal main body 7 is formed by forming recesses 6 each having a diameter larger than that of the screw hole 4 and having a female thread 5 on the circumferential surface. Reference numeral 12 denotes an additional terminal, which has a male screw 9 at one end of the synthetic resin cylinder 8, a flange 18 on the outside of the other end, and a hole with a diameter larger than the hole in the cylinder 8 on the inside. Additional terminals 12 are formed by forming recesses 11 each having a female thread 10 on the circumference.
Configure. 13 is the terminal main body 7 or additional terminal 1
a water-swellable water-stop ring that fits into the cylinders 1 and 8 of No. 2, 14;
are the recesses 6 and 11 of the terminal body 7 or additional terminal 12
15 is a terminal main body 7
or the female screw 5 of the recess 6, 11 of the additional terminal 12 ,
10, and a square tool engagement recess 19 is formed in the center of the outer surface thereof. By the way, as the water-swellable water-stop material used for the water-swellable water-stop ring 13 and the water-swellable water-stop seat 14, acrylic, vinyl, or inorganic water-swellable resins may be used. Preferred is a water-swellable polyurethane-containing flexible material made of a mixture of water-swellable polyurethane resin and natural rubber, synthetic rubber, recycled rubber, or the like. A flexible substance such as
is a polyoxyalkylene chain consisting of an oxyethylene group and an oxyalkylene group having an alkylene group having 3 to 4 carbon atoms, provided that the oxyethylene group accounts for 20 to 100% of the molecular weight. :n is a number indicating the degree of polymerization of the oxyalkene group, and the hydroxyl group equivalent is
200-2500: p is a number of 2-8, preferably 2-4); and a mixture of two or more polyether polyols; a polyisocyanate group-containing urethane prepolymer;
It can be obtained by kneading and curing a crosslinking agent with the above rubbers. Examples of the above-mentioned polyhydric alcohols include dihydric alcohols (ethylene glycol, propylene glycol, etc.), trihydric alcohols (glycerin, trimethylolpropane, etc.), tetrahydric alcohols (erythritol, pentaerythritol, etc.), pentahydric alcohols (arabitol, etc.), , xylitol, etc.), hexahydric alcohols (sorbitol, mannitol, etc.), etc. The above polyether polyol can be produced by adding alkylene oxide to such a polyhydric alcohol so as to have a desired molecular weight. Such addition may be random or block. If the proportion of oxyethylene groups is less than 20%, the expandability will be insufficient and it is not very preferable as a water-stopping material. Any polyisocyanate can be used. The isocyanate group present at the end is 1-12
%, more preferably 2-7%. The crosslinking agent has 2 to 6 active hydrogens per molecule and has an average molecular weight of 30 per active hydrogen.

In the above flexible material, it is preferable to mix 20 to 800 parts of water-swellable polyurethane resin to 100 parts of rubber. Other preferred flexible materials include a composition comprising the water-swellable polyurethane resin and rubber,
Further examples include those containing a hydraulic substance.
Hydraulic substances that can be used include portland cement, blast furnace cement, colloidal cement, gypsum, etc., and preferably a calcium aluminate-based cement quick hardening agent is used in combination with this. Such a flexible material containing a hydraulic material has the advantage of having little shrinkage even when dried. The amount of the hydraulic substance to be blended is preferably 20 to 300 parts per 100 parts of the total amount of water-swellable polyurethane resin and rubber. Further, an appropriate water-absorbing substance can be added to the flexible substance. As water-absorbing substances,
α, β having one or more carboxyl groups or groups derivable into carboxyl groups in the molecule, such as carboxyl groups, carboxylates, carboxylic imides, carboxylic acid amides, carboxylic acid anhydrides, etc.
Examples include those in which an unsaturated compound is the main component and other α,β-unsaturated compounds are added and polymerized as necessary, or those in which these are further modified with isocyanates. Examples of such water-absorbing resins include starch/acrylic acid graft copolymers, salts of styrene-maleic anhydride copolymers, crosslinking agents for sodium polyacrylate, and vinyl ester/ethylenically unsaturated carboxylic acids or derivatives thereof. Known super absorbent polymers such as saponified products can be mentioned. Additionally, the flexible materials described above can be vulcanized using a crosslinking agent such as sulfur. Further, the composition of the flexible substance is preferably adjusted so that the resulting molded article has a water expansion coefficient of 10 to 350%, more preferably 40 to 250%. B is a weir plate of concrete formwork, and through holes 20 are bored at appropriate locations. Reference numerals 21 and 21a are joint bolts, and male threads 22 and 23 are provided at both ends, respectively. 24 is a formwork clamping rod, and 25 is a screw hole at the base end of the formwork clamping rod 24. Next, its effect will be explained. () In urban areas, if the cover thickness between the wall surface of wall A and the separator 2 is not a big problem and the conventional standard dimensions are sufficient, as shown in Fig. 5, the tube of the terminal body 7 should be Water stop ring 1 on the outer periphery of body 1
3, one side of the female threaded cylinder 4 is screwed into the male thread 3 of the separator 2 up to the stopper 16, and the male thread 22 of the joint bolt 21 is screwed into the other side. Therefore, the joint bolts 21 on both sides are inserted into the through holes 20 of the weir plates B on both sides, and the male threads 23 of the joint bolts 21 are screwed into the screw holes 25 of the formwork clamping rods 24, and the weir plate B is connected to the terminal. The weir plates B on both sides are erected by being held between the main body 7 and the formwork clamping rods 24.
After that, although not shown, in the same way as before, vertical and horizontal flaps are assembled on the outside of the weir plate B, and they are tightened and fixed together with a clamping fitting via the formwork clamping rod 24 to complete the formwork. Then, concrete is poured into the inner space of the weir plate B to construct the wall A. After that, once the concrete on wall A hardens,
After dismantling the concrete formwork, connect bolts 2
Screw out 1. Next, as shown in FIG. 4, after fitting the water stop seat 14 into the recess 6 of the terminal body 7 ,
5 is screwed into the female thread 5 of the recess 6 by engaging a tool in the recess 19 thereof, and the recess 6 is filled with the water stop 14 and the male thread plug 15. () At the beach, etc., there is a lot of salt in the moisture in the air, causing wall A.
If the cover thickness between the wall surface and the separator 2 is to be greater than a certain level, as shown in FIG. The male screw 9 of the cylindrical body 8 is screwed into the female screw 5 of the recess 6 of the terminal body 7 to fix them together. Next, after screwing one side of the female threaded tube 4 of the terminal main body 7 with the additional terminal 12 into the male thread 3 of the separator 2 up to its stopper 16, one side of the joint bolt 21a is inserted into the cylinder 8 of the additional terminal 12 . Then, the male thread 22 is screwed into the other side of the female thread cylinder 4. Thereafter, by performing the same operations as in () above, after assembling the concrete formwork and constructing the wall A, the concrete formwork and joint bolts 21a can be removed. Next, as shown in FIG. 6, after fitting the water stop seat 14 into the recess 11 of the additional terminal 12 , the male threaded plug 15 is fitted into the recess 19 with a tool and the recess 11 is fitted.
1, and the recess 11 is filled with the water stop seat 14 and the male screw plug 15. (Effects of the invention) The separator terminal device of this invention has the following remarkable effects. (1) If the cover thickness between the wall surface and the separator is not a big problem in urban areas, etc., only the terminal body is used; on the other hand, if the cover thickness is larger than a certain level in areas such as beaches, By connecting an additional terminal to the above terminal body,
In addition to being able to construct concrete walls with arbitrarily small or large cover thicknesses, in any of the above cases,
By fitting the water stop seat into the recess of the terminal body or supplementary terminal and screwing in the male screw plug, the recess can be filled and the terminal surface can be finished neatly. Since the water seat and male screw stopper are used for both purposes, it is extremely convenient for production, storage, handling, and work. (2) If the above-mentioned cover thickness is large, corrosion of the separator, the metal body of the internally threaded tube, etc. due to the intrusion of water such as rainwater from the wall surface is prevented, and the aging of the concrete structure can be prevented. . (3) Water such as rainwater that permeates from the wall surface into the gap between the concrete wall and the terminal body or additional terminal,
The water-expandable water-stop ring on the outer periphery of the cylinder catches and prevents water from penetrating inside, and also prevents rainwater from penetrating into the gap between the terminal body or the additional terminal and the stopper. Water is trapped by a water-swellable water stop between them and is prevented from penetrating inwardly. Therefore, water will not penetrate from the wall surface into the separator part in the concrete wall through the gap between the concrete wall and the terminal body or supplementary terminal, or between the terminal body or supplementary terminal and the stopper. b) Preventing the separator from rusting and increasing the durability of the structure. (b) There is no risk of water containing rust flowing onto the wall surface and damaging the aesthetic appearance of the wall surface. (4) Due to the use of the above-mentioned water-expandable water stop ring and water-expandable water stop, water seeps into the gap between the concrete wall and the terminal body or supplementary terminal, or between the terminal body or supplementary terminal and the stopper. If it hits the water-expandable water-stop ring or water-expandable water-stop seat between them, that water-stop ring or water stop seat will expand and cause damage to the concrete wall and the terminal body or supplementary terminal, or the terminal body or supplementary terminal. The terminal and the stopper are strongly pressed against each other to reliably close the gap and help prevent water from penetrating into the concrete wall in the gaps between the terminal body of the separator or the supplementary terminal. (5) Since the plug is installed in the recess of the terminal body or additional terminal by screwing, the installation of the plug is reliable and firm, and the water-expandable water stop in the recess does not expand due to water penetration. However, the stopper does not come off, and its water stop is strongly pressed against the inner surface of the recess and the stopper, thereby preventing water from penetrating into the concrete wall. (6) The structure is simple and can be manufactured easily and inexpensively, and its fixation is strong.
