Elongate abutment member of plaster

Abstract

An abutment is provided for use as a start or end post of a plasterboard partition wall or as a join between two such walls which run in different directions. The abutment comprises an elongate plaster moulding designed to run between the ceiling and the floor and having an abutment surface for abutment against the end of the partition wall, in a preferred embodiment, the abutment includes a tapered edge at the abutment surface to provide a space at the join in which a skim of plaster can be applied to provide a seamless join between the partition wall and the abutment.

1 . An abutment adapted for use as a start or end post or member of a wall such as a partition wall or as a join between two such walls, the abutment comprising:
 an elongate plaster body having at least one abutment surface running along its length for abutment against an end of the wall; and   at least one plaster formation adjacent the abutment surface which extends along at least part of the length of the abutment for receiving a skim of plaster, so as to provide, upon receipt of said plaster skim only in the region of the said plaster formation, a seamless join between the abutment member and the wall.   
   
   
       2 . The abutment according to  claim 1 , wherein said at least one formation is a tapered side of the abutment. 
   
   
       3 . The abutment according to  claim 2 , wherein the angle of said tapered side ranges between 5 and 25 degrees, preferably between 10 and 15 degrees. 
   
   
       4 . The abutment according to  claim 1 , wherein said at least one formation is a recessed portion of the abutment. 
   
   
       5 . The abutment according to  claim 1 , wherein said at least one formation has a depth ranging between 1.5 mm and 6 mm, preferably between 2 mm and 4 mm. 
   
   
       6 . The abutment according to  claim 1 , wherein said abutment comprises at least one side wall which extends in a plane that is substantially perpendicular to said abutment surface to run parallel with an outer surface of said wall and wherein said at least one formation extends between said abutment surface and said at least one side wall. 
   
   
       7 . The abutment according to  claim 1 , including means for enabling alignment of the abutment with the wall. 
   
   
       8 . An abutment adapted for use as a start or end post or member of a wall such as a partition wall or as a join between two such walls, the abutment comprising: an elongate plaster body having at least one abutment surface running along its length for abutment against an end of the wall; and means for enabling alignment of the abutment with the wall. 
   
   
       9 . The abutment according to  claim 8 , wherein the means for enabling alignment comprises a formation for cooperating with the wall. 
   
   
       10 . The abutment according to  claim 9 , wherein the cooperating formation is adapted to engage with the wall. 
   
   
       11 . The abutment according to  claim 10 , wherein the cooperating formation comprises a recess in said abutment surface to receive said wall. 
   
   
       12 . The abutment according to  claim 11 , wherein the recess is shaped and sized to receive a stud in said wall. 
   
   
       13 . The abutment according to  claim 12 , wherein the recess is adapted to extend less than the entire width of the stud. 
   
   
       14 . The abutment according to  claim 11 , wherein said recess is formed from at least one plaster limb extending from said abutment surface. 
   
   
       15 . The abutment according to  claim 14 , wherein the or each said plaster limb has a further abutment surface running along the length of the abutment for abutment against a portion of said wall. 
   
   
       16 . The abutment according to  claim 15 , wherein said further abutment surface is at the distal end of said plaster limb. 
   
   
       17 . The abutment according to  claim 15 , further comprising at least one plaster formation adjacent the abutment surface which extends along at least part of the length of the abutment for receiving a skim of plaster, so as to provide, upon receipt of said plaster skim only in the region of the said plaster formation, a seamless join between the abutment member and the wall, and wherein the or each said plaster formation is adjacent said further abutment surface of said plaster limb. 
   
   
       18 . The abutment according to  claim 14 , further comprising at least one plaster formation adjacent the abutment surface which extends along at least part of the length of the abutment for receiving a skim of plaster, so as to provide, upon receipt of said plaster skim only in the region of the said plaster formation, a seamless join between the abutment member and the wall, and wherein the depth of said plaster formation is less than half the width of said plaster limb. 
   
   
       19 . The abutment according to  claim 17 , wherein the depth of said plaster formation is less than a quarter of the width of said plaster limb. 
   
   
       20 . The abutment according to  claim 1 , comprising at least one fixing substrate positioned along its length adjacent said abutment surface for allowing the plaster abutment to be fixed to said end of the wall.
