Definitions
- the present invention relates to a shaped wall insert.
- the present invention relates to a shaped wall insert for use as a means for the prevention of damp in walls.
- shaped wall inserts for such a purpose is already known.
- the inserts provide a means of attracting and subsequently expelling moisture from within walls, and typically require the drilling of a locating hole, such as in UK Patent No 2241729, wherein an inclined hole is drilled in a wall and a tubular ceramic insert is subsequently inserted into the hole.
- Other shaped inserts are shown in UK Patent No 251807, wherein inserts which are triangular or substantially triangular in cross-section and which have a cylindrical passage therethrough are inserted into an inclined hole in a wall.
- a wall insert having an interface surface providing an interface between the insert and circulating air in a hole in a wall, wherein the insert is shaped in cross-section to co-operate with the hole such that when the insert is located in the hole the interface surface of the insert inclines progressively upwardly toward the inner most end of the hole.
- the insert is constructed of a porous ceramic or plastic material which has moisture attracting properties.
- the insert may have capillaries extending through it to draw moisture to the interface surface, where it can evaporate and be carried out of the hole as water vapour.
- the hole is circular and drilled substantially horizontally in the wall.
- the hole is 50mm or less in diameter, preferably about 25 mm in diameter.
- the hole extends up to 95% of the way through the thickness of a wall. Where the wall is a 100mm cavity wall leaf the hole will extend for approximately 90 or 95 mm depth, giving a typical fall on the interface surface of 1 in 4. However this fall may be shallower (up to 1 in 10 or more) in the case of a solid wall having a greater thickness.
- the insert is preferably wedge shaped and may have a flat interface upper surface and a rounded lower portion which accords with the hole in the wall.
- the insert may be tubular, having a hole therethrough which may be adapted to receive an aforesaid interface surface or may incorporate an aforesaid interface therein.
- the insert may be fixedly retained within the hole by a suitable fixing means.
- the fixing means may be a porous, time-setting mortar or grout material.
- the hole in the wall passes through at least a portion of the wall such that the hole has one open end at the external face of the wall and is closed at the innermost end.
- the insert may be provided with a cap shaped to fit the open end of the hole.
- the cap may be provided as a separate component.
- the cap may be fixedly retained by suitable fixing means.
- the fixing means may be a porous, time-setting mortar or grout material.
- the cap has at least one hole therethrough to enable passage of air into the hole in the wall.
- a method of removing moisture from a wall comprising the steps of forming a substantially horizontal hole and placing therein a wall insert according to the first aspect of the invention.
- a wall comprising a plurality of building elements, the wall having a plurality of substantially horizontal holes formed therein, each of said holes containing a wall insert according to the first aspect of the invention.
- a ceramic or plastic insert is shown generally at 1 which has an inclined interface surface 2 and a shaped portion 3 which is designed to co-operate with a hole 4 in a wall 5.
- the hole 4 is drilled in the wall 5 at the position where the insert 1 is required.
- This hole 4 is circular in cross-section, and is drilled substantially horizontally into the wall 5 from the external face.
- the hole 4 does not pass right through the wall 5, but extends through a large portion of its cross-section.
- the insert 1 is then located within the hole 4 such that the interface surface 2 inclines progressively upwardly from the open end 6 of the hole 4 towards the closed end 7 of the hole 4.
- the hole 4 has an end cap generally shown at 8 which has holes 9 therethrough for the passage of air from a position outwith the wall 5 to a position within the hole 4.
- the insert 1 is fixedly retained within the hole 4 using a suitable porous mortar or grout material 10, wherein the mortar or grout 10 is inserted into the hole 4 prior to locating the ceramic insert 1, such that the insert 1 becomes retained on hardening of the time-setting mortar or grout 10.
- FIG. 2 there is shown an insert 1a which functions in the same way as insert 1, shown in Fig. 1.
- the interface surface 2a is dished to form a channel along which moisture collecting on the interface surface can migrate under gravity towards the open end 6 of the hole 4.
- the shaped portion 3a is similarly designed to co-operate with the internal surface of the hole 4 in the wall 5.
- a tubular insert is generally shown at 11 which has an outside casing 12 which is circular in cross-section and which has a passage 13 therethrough.
- An inclined interface surface 14 is provided in the passage 13 through the insert 11 which inclines progressively upwardly towards the distal end of the insert 11, as seen in Fig. 3.
- the inclined interface surface 14 may be formed integrally, for example by moulding, with the outside casing 12.
- the inclined interface surface may be formed on a separate insert piece which has a lower shaped portion 15 which co-operates with the cylindrical inner surface of the outside casing 12 in the insert 11.
- the insert 11 is inserted into a hole 4 in a wall 5 in a similar way to the insert of Fig. 1, such that the interface surface 14 of the insert 11 is oriented in the same way as in Fig. 2. If desired, the insert 11 is fixedly retained in the same way as the insert 1 of Fig. 1, utilising a suitable mortar or grout.
- the perforated cap may be formed integrally with the insert.
- the shape if the insert is not limited to the shapes shown in the drawings, but any shape which fits securely in a hole and has an inclined upper surface may be adopted.

Description
Claims (13)
- A wall insert having an interface surface providing an interface between the insert and circulating air in a hole in a wall, wherein the insert is shaped in cross-section to co-operate with the hole such that when the insert is located in the hole the interface surface of the insert inclines progressively upwardly toward the inner most end of the hole.
