Definitions

  • the present invention relates to a seal for a joint to be installed at the time of placing of concrete for a structure, and relates to a method of installing the seal.
  • the present invention was made in consideration of the problems mentioned above. Accordingly, it is an object of the invention to provide a seal for a joint which is composed of inexpensive structural materials in a simple manner so as to cope well with internal cavities at an near the joint and which performs a secondary sealing function as well as a primary sealing function.
  • the seal provided in accordance with the present invention is characterized by comprising a cylindrical inner core layer made of a water-unexpansible flexible material and having an internal opening; and an outer coating layer which is made of a water-expansible rubber, coats the inner core layer and has penetrating openings in the form of slits, pinholes or the like, which penetrating openings extend to penetrating openings in the inner core layer and communicate with the internal opening of the inner core layer through the penetrating openings of the inner core layer.
  • the method provided in accordance with the present invention is characterized in that the seal is disposed at the position of the joint of placed concrete; the concrete is placed; and a filling material is thereafter injected, under pressure, into the gap between the outside surface of the seal and the placed concrete through the internal opening of the inner core layer of the seal and the penetrating openings of the inner and the outer layers so that the filling material is solidified.
  • Figs. 1 and 2 show a seal 1 for a joint.
  • the seal 1 comprises a cylindrical inner core layer 2 having an internal opening 2a which is made of a flexible material such as a water-unexpansible rubber or plastic, and an outer coating layer 3 made of a water-expansible rubber which coats the inner layer.
  • the water-expansible rubber for the outer coating layer 3 is produced by adding a vulcanizing agent, a vulcanization accelerator, a filler, a plasticizer, an antioxidant and a water-expansible resin to Neoprene rubber, natural rubber or halogenated butyl rubber.
  • the vulcanizing agent is sulfur, magnesium oxide or the like, the vulcanization accelerator thiazole, imidazolo or the like, that the plasticizer is stearic acid, process oil or the like, the antioxidant amine, phenol or the like, and that the filler is calcium carbonate, magnesium oxide, carbon black, hard clay, zinc white or the like.
  • the water-expansible resin is a urethane resin capable of being swollen with water, a polyvinyl alcohol capable of being swollen with water, an acrylic resin capable of being swollen with water, or the like.
  • the outer coating layer 3 has penetrating openings 4 shown as slits extending in the longitudinal direction of the layer and located at alternated positions in the circumferential direction thereof.
  • the openings 4 penetrate the outer coating layer 3, and communicate with the internal opening 2a of the inner core layer 2 through the penetrating openings thereof.
  • the diameter of the internal opening 2a and the pressure and hardness of the inner and the outer layers 2 and 3 are set so that the internal opening is not closed due to the pressure of concrete or the pressure of the water-expanded outer layer when the concrete is placed on the seal 1.
  • a method for installing the seal 1 during placement of the concrete to make the joint is described with reference to Figs. 3, 4 and 5 below.
  • a vessel a for example, is to be made of concrete
  • the concrete is placed so that the lower portion a1 of the vessel is first made from the concrete.
  • the seal 1 is then disposed on the top of the lower portion a1 of the vessel a along the entire periphery thereof.
  • the top of the lower portion a1 may be made of surfaces of different heights so that the seal 1 can be disposed more precisely and easily on the top thereof.
  • the seal 1 is secured to the top by an adhesive or nails 5 shown in Fig. 4.
  • Molding members b and c are then provided outside and inside the lower portion a1 of the vessel a.
  • a tube 6 is removably inserted into the internal opening 2a of the seal 1 at one end thereof in such a manner that one end portion of the tube extends outside the molding members b and c. Concrete is then placed again so that the upper portion a2 of the vessel a is formed. During the solidification of the concrete, the outer coating layer 3 of the seal 1 is expanded with water so as to remove internal cavities in the concrete in order to generate a primary sealing state.
  • Solidifiable liquid filling material 7 such as a silica grout and cement milk is then injected, under pressure, into the internal opening 2a of the seal 1 through the tube 6 so that the penetrating openings 4 of the seal are enlarged by the pressure, and the filling material spreads into the gap between the outside surface of the seal and the concrete and into internal cavities in the concrete and fills the gap and the cavities in order to generate a secondary sealing state.
  • the injection of the filling material 7 is performed when a water leak is found after the concrete placed for the upper portion a2 of the vessel a has solidified.
  • the injection of the filling material 7 may be omitted if a water leak is not found.
  • the seal 1 is installed in the concrete vessel a as described above, the present invention is not confined to this method but also applies to a method whereby the seal is installed in a different concrete structure such as a pool or a reservoir.
  • the penetrating openings 4 are provided in the seal 1 so as to extend in the longitudinal direction thereof, because if the openings extended in the circumferential direction thereof, they would be enlarged at the bent portions of the seal so as to allow the concrete to enter into the internal opening 2a of the seal. Therefore, it is preferable that the angle between the direction of each penetrating opening 4 and the longitudinal direction of the seal 1 is not more than 45 degrees.
  • Fig. 6 is a sectional view showing the state in which a seal material 11 is applied according to another embodiment of the invention.
  • the seal 11 is integrally provided on both sides of its bottom portion with flanged portions 18.
  • the flanged portions 18 are fixed to the end face of the vessel by inserting fastening members such as nails 5 thereinto.
  • reference numeral 12 denotes an inner core layer
  • numeral 13 denotes an outer coat.
  • Fig. 7 is a sectional view showing the state in which a seal 111 is applied according to still another embodiment of the invention.
  • the portions into which the fastening members 5 should be inserted are clearly indicated, and hence it is possible to insert the fastening members 5 at both end portions in an exact manner with ease. Furthermore, since the fastening members 5 would not penetrate the hollow opening 2a, it is advantageous that the effective opening area of the hollow opening is not decreased.
  • a seal for a joint is composed of an inner core layer made of a water-unexpansible flexible material and having an internal opening, and an outer coating layer made of a water-expansible rubber which coats the inner core layer and is provided with penetrating openings through which a filling material can be easily introduced into concrete. For that reason, expanding the outer coating layer to remove internal cavities in the placed concrete to generate a primary sealing state, and introducing the filliing material into the concrete to generate a secondary sealing state, can be performed with a simple arrangement at lower cost.
