[0001] The present invention relates to a support plate for tiles to be set on the surface
of a building.
[0002] So far, tiles have been set on the surface of a building by applying mortar on the
surface or on the tile back and pressing them against the surface. Consequently, the
work of tiling with uniform spaces between the tiles and making their surfaces even
has required a great deal of skill.
[0003] The conventional tiling method has another disadvantage that the lower rows of tiles
will come off if the load of the tiles laid thereupon exceeds the limit which can
be withstood by them. Because of this possibility, the number of rows of tiles which
can be set in one day was restricted.
[0004] The conventional tiling method has still another disadvantage that it requires a
large quantity of mortar and that liquid cement has to be sprayed upon the surface
of mortar for the acceleration of the hardening of mortar with a concomitant result
of soiling the tiles and the surroundings with the cement.
[0005] It is an object of the present invention to provide a support plate for tiles which
obviates the necessity of a great deal of skill for setting tiles with uniform spaces
between the tiles and making their surfaces even.
[0006] It is another object of the present invention to provide a support plate for tiles
which permits tile-setting without restrictions on the number of rows of tiles which
can be set in one day and yet precludes the possibility of the peeling-off of the
lower tiles.
[0007] In accordance with the present invention, there is provided a support plate for tiles
comprising a rectangular metal plate having a plurality of tile support pieces, said
support pieces each having a web portion perpendicular to said metal plate and a flange
portion parallel with said metal plate.
[0008] With the above-described objects in view and as will become apparent from the following
detailed description, the present invention will be more clearly understood in connection
with the accompanying drawings.
[0009]
Fig. 1 is a partially cutaway front view of part of a wall tiled by use of the support
plates according to the present invention;
Figs. 2 to 4 are front views of the first, second and third embodiments;
Fig. 5 is a sectional view taken along line V-V of Fig. 2;
Fig. 6 is a sectional view taken along line VI-VI of Fig. 3;
Fig. 7 is a sectional view taken along line VII-VII of Fig. 4; and
Figs. 8 and 9 are sectional views of other embodiments.
[0010] Referring now to Fig. 1, a plurality of rectangular metal plates 1 are nailed or
otherwise mounted on the surface of a building. L-shaped tile support pieces 5 are
struck out of the surface of each metal plate 1 in such positions as to conform to
the positions of tiles 2 to be arranged on the surface of the metal plate 1.
[0011] In the first embodiment shown in Figs. 2 and 5, the tile support pieces 5 are struck
out of the surface of each metal plate 1 at intervals. Their end portions are bent
in opposite directions, leaving webs 6 perpendicular to the metal plate 1. Flanges
7 are bent so as to run parallel with the metal plate 1. Each tile 2 designed for
this embodiment is supported by two pairs of vertically spaced support pieces 5. (Fig.
2) In each pair of vertically spaced support pieces 5, the vertical length of the
upper (i.e. downward) flange 7 is longer than that of the lower (i.e. upward) flange
7.
[0012] To mount the tile 2 on the metal plate 1 of this embodiment, the upper (downward)
flanges 7 are fitted into a groove 3 provided in the upper edge of the tile 2. Then
the lower (upward) flanges 7 are allowed to fit into a groove 4 provided in the lower
edge of the tile 2. For this way of mounting the tile 2 on the metal plate 1 of this
embodiment, the groove 3 should be deeper than the groove 4.
[0013] In the second embodiment shown in Figs. 3 and 6, all the flanges 7 are bent in the
same (i.e. upward) direction. Each tile 2 designed for this embodiment is provided
with two grooves 8 running parallel with the metal plate. One of the grooves is provided
in the back middle of the tile 2, while the other is provided in its lower edge. To
mount the tile 2 on the metal plate 1 of this embodiment, the tile is lowered so that
the upper edges of the flanges 7 will fit into the L-shaped grooves 8.
[0014] In the third embodiment shown in Figs. 4 and 7, all the flanges 7 are bent in the
same (i.e. upward) direction. Each tile 2 designed for this embodiment is provided
with a single L-shaped groove 8 in the back thereof to allow the flanges 7 to fit
therein so that it can be mounted on the metal plate 1 of this embodiment in the same
manner as in the second embodiment. Each time a tile 2 is mounted on the metal plate
1, tongues 11 formed by C-shaped cuts 10 in the metal plate 1 are pryed by means of
a screwdriver or the like so as to bring the lower edges of the tongues 11 into contact
with the upper edge of the tile 2 and thereby secure the tile in position.
[0015] In the fourth embodiment shown in Figs. 8 and 9, the tile support pieces 5 are substantially
the same as those of the first embodiment except that the upper and lower flanges
7 are of the same length. Each tile 2 designed for this embodiment is provided with
an L-shaped grooves 8 (Fig. 8) or a T-shaped groove 15 (Fig. 9) in the back thereof.
To mount the tile 2 on the metal plate 1 of these embodiments, the groove 8 or 15
is filled with mortar and then the tile 2 is pressed against the metal plate 1 and
forced down so as to allow the upward flange 7 to fit into the vertical portion of
the L- or T-shaped groove 8 or 15. Since the upper and lower flanges are of the same
length, the support plates can be mounted upside down.
[0016] Although only two rows of tiles 2 are mounted on each metal plate 1 in the preferred
embodiments shown in the drawings, the metal plate 1 may be of a larger size so as
to be capable of bearing more than two rows of tiles 2.
[0017] In the embodiments shown in the drawings, the metal plates 1 are secured to the surface
of a building by means of nails 9 (Figs. 5, 6 and 7) driven through holes 12 (Figs.
2, 3 and 4). However, the metal plates 1 may be secured by spot welding.
[0018] If a space is left between the back of the metal plate 1 and the surface of a building,
the space may be stuffed with mortar or foamed plastics poured through the openings
14 formed by striking the tile support pieces 5.
[0019] When the necessary number of tiles 2 have been mounted on the metal plates 1, the
space left between adjacent tiles 2 is filled with mortar 13 (Fig. 7).
[0020] The present invention obviates the necessity of stretching a string for aligning
each row of tiles 2, and gives a good appearance to the tiled wall because of uniform
space left between the tiles 2.
[0021] The present invention has further advantages that it permits tile-setting without
restrictions on the number of rows of tiles 2, that the metal plates 1 can be manufactured
at low cost because the tile support pieces 5 can be formed simply by press work,
and that the tiles 2 can be protected from cracking or peeling-off even if the tiled
wall is jolted.
[0022] The present invention has a still further advantage that since the metal plate 1
can be made in any curved form, the tiles can be easily set even on a curved wall
surface.
