1 Claim.
My invention relates to improvements in wall board joints, and the object of the invention is to devise a simple, strong and durable joint between an edge of a wall board and the abutting edge of a plaster coat of a plastered surface which will anchor one to the other permanently in close contact, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.
Fig. 1 is a plan sectional view showing a portion of a wall board and its supporting structure, a plastered surface and my connection between the wall board and the plastered surface.
Fig. 2 is a similar view to Fig. 1 showing my 1 device applied to the connection between a wall and ceiling surface.
Fig. 3 is a fragmentary detail of the key plate.
In the drawing like characters of reference indicate corresponding parts in each figure.
Referring to Fig. 1.
1 indicates a supporting structure. 2 is a wall board provided with a recessed edge portion 2 3 is a tile wall. 4. is a key plate counter sunk in the recess 2 and provided with an extension 4 formed integral therewith, such extension being in the form of a series of parallel strips or tongues having offset ends forming a key connection when embedded as hereinafter described.
5 is a plaster coat for the wall 3 in which the key plate extensions 4 and their offset ends 4 are embedded. The exposed surface of the coat 5 is formed flush with the exposed surface of the wall board 2, the plaster being carried into the recess 2 to cover the plate 4 through which nails 6 extend into the supporting structure 1.
In Fig. 2, I have shown the construction of Fig. 1 applied to connecting the wall board covupper edge.
9 is a tile ceiling base.
10 isa plate which is counter sunk in the recess 8 and secured in position by nails 11 extending through the plate and wall board into the supporting structure 7. The upper edge of the plate 10 is down-turned as indicated at 10 and provided with an extension 12 in the form of strip formation corresponding to that illustrated in Fig. 1.
13 is a plaster coat covering the surface of the tile 9 so as to embed the strips 12 therein as indicated, the coat 13 extending into the recess 8 and downward to the base of the recess as at 8 flush with the surface of the wall board 8. By this means, it will be seen, a perfectly flush joint will be formed, the wall board being rigidly anchored in the plaster coat so that there will be no danger of the coat and wall board spreading apart.
What I claim as my invention is: g
The combination with a supporting structure of a wall board having its inner face recessed at its edge, a metallic plate counter sunk in the recess and provided with a flexible extension integral therewith and formed to furnish a key look when embedded,
securing means extending of the wall board.
DAVID MCCHESNEY.
