Definitions

  • This invention relates to the application of pointing material such as mortar to brickwork and other similar structures in the process known as "pointing" in which mortar or a similar pointing material is applied to crevices between laid bricks, stones, etc., to fill such crevices either when a wall is originally constructed or subsequently by way of repair.
  • pointing material such as mortar to brickwork and other similar structures in the process known as "pointing" in which mortar or a similar pointing material is applied to crevices between laid bricks, stones, etc., to fill such crevices either when a wall is originally constructed or subsequently by way of repair.
  • pointipg materials comprise a wet mix of generally granular matter including a cementitious binding agents.
  • a method of pointing brickwork or other similar structure by the application of mortar or other similar pointing material is characterised in that the pointing material is contained within a tube having a tapering nose portion terminating in a nozzle and said material is displaced through said nozzle directly into crevices where pointing is required by means of a piston having sealing engagement with the internal surface of said tube.
  • the nozzle is shaped to afford a rectangular or square opening at its outlet end to form the displaced materiat into a ribbon of corresponding sectional shape.
  • the piston is preferably advanced along the length of the tube by means of a manually operable plunger.
  • the piston may incorporate a seal made of resilient material, and preferably having a concave outer face so that the seal engages the tube at positions spaced axially of the tube. Most conveniently the nozzle is aligned with the axis of the tube.
  • the invention also resides in apparatus for performing said method, such apparatus comprising a tube to contain a pointing material, the tube having a tapering nose portion terminating in a nozzle through which the material can be discharged, a piston having sealing engagement with the internal surface of said tube and manually operable means for advancing saitl piston along the length of said tube towards said nozzle.
  • the tube is preferably supported removably in a cradle so that it can be separated from the operating means for the purpose of filling with the pointing material.
  • the operating means may be rotatable relative to the cradle about an axis coincident with that of the tube and may include a hand grip and a lever coupled to a rod on which the piston is carried.
  • the pointing material used may be of generally conventional type, but may be made rather wetter than is normal for application by trowelling, and to prevent shrinkage problems on drying, the mix may include an air entraining agent which is compressed during passage of the material through the nozzle, and then expands to compensate for shrinkage as the material dries.
  • Water is added to this mixture to produce a settable mortar, and for the purposes of the invention it is preferred to make the mix wetter than would normally be used for manual application by trowelling-in order to assist flowability. Typically, approximately two litres of wafer would be used with 25 kilogrammes of the dry mix.
  • the mix preferably also includes approximately 1% of a suitable air entraining substance.
  • Such apparatus resembles a conventional mastic gun in that it incorporates a cradle structure 10 for the reception of a container 13 for the pointing material, a rod I I which extends axially of the container and carries at its forward end a piston 12 which, in use, is received within the container 13.
  • the rod I J is adapted to be driven along the length of the container by means of a known type of manual operating mechanism 14.
  • this mechanism includes a manually operable lever 15 which is pivotally mounted on an associated hand grip 15a and at its upper end bears on an apertured plate 16 which is loosely assembled on the rod I in such a manner that it can rock against an abutment 17 and thereby grip the rod to cause it to be advanced as the lever 15 is pulled towards the hand grip 15a.
  • a return spring 18 causes the plate 16 to slide rearwardly along the rod back into contact with the abutment 17 when the lever 15 is released.
  • a second apertured plate 19 is provided, which reacts on an abutment 19a and acts in the opposite direction to plate 16 so as normally to prevent reverse movement of the rod 11.
  • the plate 19 is displaced manually against the action of a spring 20, the rod I can be retracted manually by means of the knob 21.
  • the seal 24 is made of a suitable resilient material and preferably affords a somewhat concave peripheral outer surface 26 whereby it engages the tube 22 at two axially spaced positions and therefore acts as a double seal. Additionally, the seal 24 effectively acts as a scraper as it moves in either direction, thereby ensuring that the inner surface of the tube is maitained in a clean and smooth condition despite the nature of the mortar mix.
  • the piston 12 should engage sealingly with the inner surface of the tube 22, partly to prevent water being squeezed out of the wet mix when pressure is applied, and draining away past the piston, and thereby altering the consistency of the mix, and partly to enable hydrostatic pressure to be applied throughout the bulk of the material to enhance flowability. Further, due to the particulate nature of the mix, it is highly desirable for the seal 24 to have a wiping action to prevent solids accumulating on the interior wall of the tube in such a manner that the seal could be locally distorted and allow water to escape.
  • the cradle might not be rotatable in order to simplify construction, and indeed instead of using a container which is loosely assembled with a cradle, it might alternatively be possible to assemble the operating mechanism directly with the open end of the container. Such an arrangement would be particularly suitable for use with containers which are supplied filled with a quantity of wet mix, ready for use.
  • the nozzle 23a and nose portion 23 are formed as part of the container 13, it would alternatively be possible for the cylinder 22 to be formed separately from the nose portion and nozzle, which could then comprise a separate assembly carried by or forming part of the cradle 10.
  • the nozzle 23a is aligned with the axis of the cylinder 22 and disposed centrally relative to the conical nose portion 23.
  • the sides of the conical nose portion preferably toper at an inclined angle relative to the axis of the cylinder which is between about 30° and 45 0 .
  • the illustrated gun is manually operated by a known mechanism, it will be appreciated that the rod I may be driven by any suitable means, whether manual or mechanised.
  • the container 13 may be provided with interchangeable nozzles 23 having different outlet dimensions to suit different applications, or a range of interchangeable containers may be provided, each with a different outlet nozzle.
  • the gun may be produced in a range of different sizes adapted for holding varying quantities of mortar.
