Definitions

  • This invention relates to a method for sealing joints and to a device suitable for use in such a method.
  • a widely practised method of forming an elastic or plastic seal capable of with standing the expansion, contraction and weathering to which such joints are subjected comprises introducing into the joint a paste-like sealant or caulking material
  • a paste-like sealant or caulking material may be silicone or organic and may cure or otherwise harden to an elastic solid, or it may remain in a non-cured plastic state.
  • Such materials are applied to the joint through a conical- or cylindrical-shaped nozzle which may be detachable and re-usable or which may be permanently attached to the sealant reservoir. According to the recommended technique the sealant is pushed ahead as it emerges from the nozzle so that a uniform bead is obtained.
  • a process for the sealing of a joint between adjacent members, the said joint having walls and a floor which comprises introducing a sealant composition into the joint by means of an applicator nozzle member and thereafter shaping the exposed surface of the sealant with a shaping tool characterised in that the sealant composition is injected under pressure in proximity to the floor of the joint, the shaping tool is integral with the applicator nozzle member and positioned in a trailing spaced relationship thereto, and the shaping edge or surface of the shaping tool is positioned such that its depth of penetration into the joint is less than the depth of penetration of the discharge orifice of the application nozzle member.
  • the sealant composition is injected into the joint in proximity to the floor thereof.
  • the floor of the joint may be the normal constriction or closure formed at the bottom of the joint during the building of the structure, and may be for example of cement, earth or other inorganic material. More preferably, however, the floor of the joint is formed of a material which acts as a bond breaker.
  • the use of such bond breakers involves placing in the joint an extensible and/or non-adherent material which prevents sticking of the sealant to the natural floor of the joint and thereby allows the seal to stretch freely during expansion.
  • the packing material also presents a convex surface to the sealant thereby causing the sealant to assume a concave profile.
  • Suitable bond breaking materials include glass fibres, jute, pvc, urethane foam and polyethylene foam rod, the latter being preferred when a silicone sealant is employed.
  • the joint Prior to the injection of the sealant composition the joint may, if necessary, be prepared employing conventional practices. For example, the joint may be sawn or abraded to.achieve the desired shape and dimensions or to remove contaminants which may prevent satisfactory adhesion of the sealant to the wall portions.
  • the shaping tool is integral with the applicator nozzle member and preferably has a shaping edge which imparts a smooth surface to the applied sealant while pressing the sealant against the surfaces of the joint.
  • the shaping edge may be convex toward the sealant or may be, for example, substantially straight with rounded corners, the latter being more suitable for use in wide joints.
  • the process of this invention is particularly suitable for use with silicone-based sealant compositions. It may, however, also be employed in the application of other paste-like sealant or caulking materials, for example polysulphides, polyurethanes and rubber mastic compounds.
  • the process of this invention is particularly suitable for sealing joints in highway pavement, for example expansion/ contraction joints and longitudinal joints; but can also be applied to other structures where adjacent members define therebetween a narrow space having wall and floor portions, for example floors of industrial buildings, drives, parking areas, airfields and other military installations, terraces bridges, footpaths and docks.
  • Figure 1 is a cross section of the device viewed from one side
  • Figure 2 is a front elevation of the shaping tool
  • Figure 3 is a perspective view of an elongated form of the shaping tool
  • Figure 4 is a perspective view of the device according to this invention above a sealed joint shown partly in section.
  • FIG. 1 there is shown an application nozzle member 1 having an upper portion 2, adapted for attachment directly or indirectly to a reservoir for storing the sealant composition, and a discharge orifice 3.
  • a plate 4 is slidably mounted on the applicator nozzle 1 and contains a grub screw 5 set into a collar portion 6.
  • Fixed to, or made part of, the plate 4 is a shaping tool 7 as shown in front view in Figure 2.
  • the member 1 may be of any appropriate cross section but is most conveniently cylindrical in shape.
  • the device In use the device is connected to the sealant reservoir by way of the attachment portion 2 which may, if desired, be internally threaded for this purpose.
  • the plate 4 is laid across the joint and, if necessary, the depth of penetration of the discharge orifice 3 into the joint is adjusted by raising or lowering the nozzle member in the plate and fixing its position by tightening the grub screw 5.
  • the grub screw 5 When the device is intended for use in joints of constant fixed depth the grub screw 5 may be omitted and the plate 4 made integral with or permanently fixed to the applicator nozzle.
  • the relative positions of the discharge orifice 3 and the edge of the shaping tool 7 may also be rendered adjustable, for example by provid - ing the tool 7 with a fixing slot in place of a round screw hole.
  • the shaping tool may be made removable and supplied in a range of sizes and shapes to match joints of various widths. In general, joints between adjacent members of constructions, such as highway pavements, vary from about 5 mm to about 40 mm. Also the trailing surface of the shaping tool may be extended as illustrated in Figure 3 to provide for an increased contact time with the sealant.
  • the outer dimensions of the discharge orifice portion should be such as to permit appropriate penetration into the joint.
  • the tip portion of the orifice may be formed into a flattened, ellipsoidal section to permit such penetration.
  • Figure 4 represents a front perspective view of one embodiment of a device according to this invention above a sealed joint shown partly in section.
  • the numbers correspond to those employed in Figure 1 and in the sealed joint portion of the figure there is shown the concavely-profiled sealant 11 which has been injected over a bond breaker 12 (e.g. a rod of polyethylene foam).
  • a bond breaker 12 e.g. a rod of polyethylene foam
