Description

  The present invention relates to a water-stopping test jig, and is intended to confirm the water-stopping property of a flexible water-stopping member that stops joints of concrete structures such as reservoirs and waterways. The test can be performed without affecting the mounting portion of the member.

  In large concrete structures that make up reservoirs and clean water ponds that store domestic and industrial water, etc., and water supply and sewerage channels, it is difficult to avoid concrete cracks. It is generally performed.

  Various proposals have been made regarding the joint structure of a concrete structure. In general, a joint water-stopping member formed with a slack in the width direction of the joint part is provided in the structure in order to prevent water loss. .

  For example, as shown in FIG. 11, the conventional joint structure and the countermeasure for water loss are a groove in the center of a flexible joint waterproofing member 3 made of rubber or the like with respect to the joint part 2 of the concrete structure 1. An anchor bolt 4a and a nut 4b as a fixing tool in which the joint portion 2 is closed by the slack portion 3a and a locking portion 3b in which two rows of parallel projections joined to the flat plate or the housing on both sides are arranged is installed in the housing. It is fixed to the concrete structure 1 which is a frame.

  Then, by tightening the nut 4b, the locking portions 3b such as the protrusions of the joint water-stopping member 3 are crushed and pressed against the surface of the concrete structure 1 which is a casing to prevent water leakage from the joint portion 2. is doing.

  In such a joint structure, when the tightening force of the nut 4b is not uniform or when the locking part 3b such as the protrusion is deformed, sufficient water-stopping performance is not exhibited. There may be a test to check the water stoppage after construction.

  For such a water-stopping confirmation test, for example, a test apparatus disclosed in Patent Document 1 is used.

  As shown in FIG. 12, the test apparatus 10 includes an outer tube 11 and an intermediate tube 12, and the outer tube 11 has a cylindrical shape with a closed upper end. A screw 13b is formed on the outer peripheral portion to form a connecting portion 13 for connecting a connection pipe 14 for supplying a sample from the leakage confirmation sample supplying portion, and a groove 11a for packing 15 is provided at the lower end. A flange 11b is formed.

  The middle tube 12 has a shape similar to that of the outer tube 11 and is disposed inside the outer tube 11 and supported by the coupling members 16 from four directions, and the test device 10 is attached to the anchor bolt 4a on the inner periphery thereof. A female screw 12a is formed.

  In such a test apparatus 10, the middle tube 12 disposed inside the outer tube 11 is attached by being screwed to the anchor bolt 4 a via the pressing plate 17, and is attached to the flange 11 b at the lower end of the outer tube 11. When the supply of water or the like is received in the outer pipe 11 by the packing 15 such as an O-ring, the leakage from the outer pipe 11 is prevented.

  And the water etc. which are a leakage confirmation sample are supplied to the coupling | bond part 13 of the outer tube | pipe 11 from the pipe 14 connected to the sample supply part which is not shown in figure.

Thereby, the space A between both protrusion rows of the joint part water-stopping member 3 communicates with the inside of the outer tube 11 of the test apparatus 10 via the bolt hole of the joint part water-stopping member 3 and the bolt hole of the pressing plate 17. If there is a problem with the water-stopping property of the joint water-stopping member 3, the supplied water will leak from the edge of the joint-water-stopping member 3, and the water-stopping defective portion can be easily confirmed.

  A flexible water-stopping member fixed by a bolt type in which the water-stopping test jig 20 is installed and a waterstop test is performed is the U-shape of the concrete structure 1 as already described with reference to FIG. In contrast to the joint portion 2 having the groove, a slack portion 3a at the center of the flexible water-stopping member 3 formed of a flexible material such as rubber is disposed in the groove of the joint portion 2. In addition, it is configured to include a locking portion 3b formed with two rows of parallel protrusions that are joined to a flat plate on both sides or a frame that is the concrete structure 1, and is planted in the concrete structure 1 that is a frame. It is installed in a state of being in close contact with the concrete structure 1 which is a casing through anchor bolts 4a and nuts 4b and pressing plates 17 as fixed fastening members, and from the joint portion 2 by the flexible water stop member 3 Prevent water loss That.

  The water stop test jig 20 for testing the water stop state of such a flexible water stop member 3 includes a jig main body 21, which is applied to the side surface of the flexible water stop member 3, and is a casing. A fluid chamber 21a that is sealed against the surface of a certain concrete structure 1 can be formed, and a fluid supply hole 21b and a fluid discharge hole 21c that supply a pressurized fluid for testing in communication with the fluid chamber 21a. Is formed.

  The jig body 21 is a thick plate and has a length corresponding to the range to be inspected, and faces the side surface of the jig body 21 facing the side surface of the flexible water-stopping member 3 and the surface of the concrete structure 1. A corner portion with the lower surface is opened and the inside thereof is a hollow fluid chamber 21a. A fluid supply hole 21b and a fluid discharge hole 21c for the test fluid communicating with the fluid chamber 21a are formed from the upper surface of the jig body 21. It is.

  Further, as shown in FIGS. 3B and 4A, the jig main body 21 is integrally provided with a protruding portion 21e on the upper part of both side surfaces facing the side surface of the flexible water blocking member 3. The upper side edge of the flexible water blocking member 3 is pressed by the side surface of the jig main body 21 and the lower surface of the protruding portion 21e.

  In order to attach the jig body 21 to the side surface of the flexible water-stopping member 3 and the surface of the concrete structure 1 in a close contact state, a side-surface contact mechanism 22 and a bottom portion contact mechanism 26 are provided. Is fixed to the concrete structure 1 which is a frame and is fixed by using anchor bolts 4a and nuts 4b and pressing plates 17 which are fixed tightening members, but in this case, the tightening state of the flexible water stop member 3 is affected. Is not reached.

  For this reason, the side contact mechanism 22 for bringing the jig body 21 into close contact with the side surface of the flexible water blocking member 3 constitutes a clamping member attached with the pressing plate 17 fixed via the anchor bolt 4a and the nut 4b. The inner clamping member 23 and the outer clamping member 24 are provided, and the inner clamping member 23 on the center side of the joint of the pressing plate 17 is locked to the inner side surface and the downward projecting portion 23a is applied to the upper surface. 23b and a standing portion 23c protruding upward on the outside of the abutting plate portion 23b are integrally formed, and a fastening bolt 23d is attached to the standing portion 23c at a right angle. Further, the outer clamping member 24 paired with the inner clamping member 23 has a contact plate portion 24a applied to the joint outside of the pressing plate 17 and a tightening portion 24c formed with an attachment hole 24b through which the tightening bolt 23d communicates.

And the press bolt 28 is screwed in the screw hole 27f of the lower horizontal part 27b, and the jig | tool main body 21 is pressed on the surface of the concrete structure 1, and is stuck.

  Thereby, the opening of the fluid chamber 21a of the jig main body 21 can be closed by the flexible water-stopping member 3 and the housing 1, and the locking portion 3b of the flexible water-stopping member 3 and the concrete structure 1 can be closed. The fluid chamber 21a can be communicated with the surface.

  In this state, pressurized water is supplied as a test pressurized fluid from the fluid supply hole 21b of the jig body 21 to the fluid chamber 21a, and a pressure gauge is connected to the fluid discharge hole 21c via a switching valve. By confirming that the water is retained, it is possible to perform a water-stop test.

  In addition, when there is a problem with the water stop, the pressure of the test pressurized fluid cannot be maintained, and the test pressurized fluid leaks from the water stop portion of the flexible water stop member 3.

  And after completion | finish of a test, the fluid chamber 21a is open | released by removing the jig | tool main body 21, and the pressurized fluid for a test does not remain | survive.

  According to such a water stop test jig 20, it is possible to simply install and perform a water stop test without affecting the water stop state of the flexible water stop member 3.

  In addition, according to the water stop test jig 20, not only the protrusion parallel to the joint direction but also the protrusion orthogonal to the fixed interval is provided on the engaging portion 3b of the flexible water stop member 3 and attached in a partitioned state. In the conventional test device attached to the anchor bolt, only the inside of the compartment can be tested, and the outer portion of the orthogonal projection cannot be tested.

  A waterproof test jig 20C applied to a boltless type in which such a flexible waterproof member 3A is supported and fixed using the fixed arm member 19 without directly fixing the flexible waterproof member 3A to the concrete structures 1 and 1 with the anchor bolt 4a. Then, the same jig body 21 as the water stop test jig 20 is used, and the same side contact mechanism 22 is used, and the holding member 18 includes an inner holding member 23 and an outer holding member 24. The clamping bolt 23d is installed so as to be sandwiched, and the through hole 25a of the key 25 fitted in the key groove 21d of the jig main body 21 is inserted and tightened with the nut 25b. The jig body 21 is brought into close contact.

  Since the position of the anchor bolt 4a is different, the bottom contact mechanism 29 that closely contacts the jig body 21 to the surface of the concrete structure 1 includes, for example, a flat plate-shaped fixing member 29a as shown in FIGS. Insertion holes 29c of fixing bolts 29b corresponding to at least two anchor bolts 4a and screw holes 29d for at least two pressing bolts 28 are formed, and the fixing members 29a are fixed to the anchor bolts 4a. The size of the fixing member 29a and the arrangement of the screw holes 29d are determined so that the holes 29d face the surface of the jig body 21. Then, a long nut 29e for fixing to the anchor bolt 4a is used. After the long nut 29e is screwed on the nut 4b or in place of the nut 4b and screwed into the anchor bolt 4a, the fixing member 29a is placed on the fixing bolt 29b. It is intended for tightening.

  The other structure of the water stop test jig 20 </ b> C is the same as the water stop test jig 20 already described, and the water stop test pressurized fluid is put into the fluid chamber 21 a in the same manner as the water stop test jig 20. A water stop test can be performed by supplying and confirming that the pressure is maintained with a pressure gauge or the like.

  Therefore, according to the water stop test jig 20C, even if the test pressurized fluid cannot be supplied via the anchor bolt 4a, the water stop test can be easily installed.

  In addition, a pressure sensor is provided in the fluid discharge hole 21c as a pressure detection means, and a change in pressure after a lapse of a certain time is compared and displayed by a timer, or an alarm is issued when the change exceeds a set value. By doing so, it is possible to automatically detect the quality of the water-stopping state, display and alarm it, and further facilitate the water-stopping test.
