Description

[Detailed description of the invention] Industrial application field This invention is used in the field of tile manufacturing to hold white tiles vertically (the center line of the valley is oriented vertically) or horizontally (the center line of the valley is oriented horizontally). The present invention relates to a vertical and horizontal tile holder used for drying and firing processes, and more particularly to a vertical and horizontal tile holder made of cast material with an improved structure of the lower end support.

Prior Art A conventional vertical and horizontal tile holder, as shown in a typical example in Fig. 7 (described in Japanese Utility Model Application Publication No. 119199/1983), consists of two parallel horizontal frame members 1 between 2
A vertical beam 2 made of a solid steel rod is provided, and a horizontal lower end support part 3 that supports the lower end front edge of the horizontal tile and a horizontal lower end support part 3 that supports the lower end front edge of the vertical tile are provided approximately at the center of the vertical beam 2. A lower end support part 4 for vertical use is provided respectively, and a back support part 5 for supporting a relatively upper position of the back surface of the tile is provided in the middle part between the adjacent vertical beams 2.

In particular, the vertical lower end support part 4 is
Formed as both end edges of a rectangular plate-shaped steel piece 6 with a height h that secures the height to securely support the lower front edge of the vertical tile placed on top (see tile A in Figure 3). has been done.

On the other hand, the lower end support part 3 of the horizontal tile (see tile B in FIG. 3) is slightly larger than the vertical lower end support part 4 and is positioned further away from the back support part 5.
A short steel bar piece is erected vertically upward in the shape of a pin and welded to the center between the two parallel steel pieces 6. In order to prevent the lower end edge of the horizontal tile supported by the horizontal lower end support part 3 from coming into contact with the steel piece 6. Auxiliary support parts 7, 7 of appropriate height are stacked on the horizontal frame members 1, 1, and the lower edge of the horizontal tile is placed on the auxiliary support part 7, floating slightly higher than the steel slab 6. It is designed to support the

Next, in the case of the vertical and horizontal tile holder described in Utility Model Application Publication No. 57-34000, although not shown, it is a rectangular shape with a height dimension that reliably supports the lower front edge of the vertically oriented tile. A frame body with a diamond-shaped planar shape is assembled by combining four plate-shaped steel pieces, and the two diagonal corners of the frame body are formed as vertical lower end supports, and the inside of the diamond-shaped frame body is It has a structure in which a horizontal lower end support portion is provided protruding from approximately the center portion.
In order to ensure that the lower end of the horizontal tile does not come into contact with the diamond-shaped frame and is supported by the horizontal lower end support, auxiliary supports are also installed in a stacked manner on the horizontal frame. The lower end of the horizontal tile is supported by being placed on this auxiliary support.

Problems to be Solved by the Present Invention In recent years, kilns have been built smaller with the minimum required volume in order to improve thermal efficiency, and the ceilings of kilns are low. However, in the conventional horizontal tiles, the auxiliary support part 7
Because the tiles are supported high enough to rest on top of them, this can cause accidents such as tiles hitting the ceiling of the kiln and collapsing or toppling over. In addition, in a two-tiered kiln, of the tiles stacked in two tiers, the lower tier cannot be used because it is supported by the upper shelf, or if used forcibly, the upper shelf may sag during the firing process. There was a problem in that the tiles on the lower tier would be defective because they would press against the tiles on the lower tier.

The lower end of the vertical tile is placed directly on the horizontal frame members 1, 1 and supported by the vertical lower end support part 4, but the tile accidentally comes into contact with the ends of the auxiliary supports 7, 7. If the firing process is carried out in this state, the curvature of the valley may become distorted due to thermal contraction of the tile and thermal expansion of the vertical frame 2, resulting in a defective product.

Therefore, the length l of the auxiliary support 7 is made as short as possible, but if this is done, carelessness or work errors may occur when holding the horizontal tiles upright.
Or, the lower end of the horizontal tile may easily slip off and come off from the auxiliary support 7 due to vibration or impact during movement.
Accidents often occur in which tiles become distorted and become defective products when they go into the firing process as they are.

The larger the width W between the horizontal frame members 1, 1, the lower the distortion occurrence rate of the tile (as proven by various data). If you try to enlarge W, you will have to proportionately shorten the length l of the auxiliary support 7, which will make the above-mentioned problem even worse, so the problem is that the width W cannot be increased at will. It was hot.

The higher the height H of the back support part 5 is and the higher the position of the tile is supported, the more stable the support state of the tile will be and the less chance of distortion. Horizontal roof tiles that are supported highly inevitably suffer from poor support stability and a high incidence of distortion.

In the case of the round bar welded structure shown in Fig. 7, the auxiliary support 7 is a round bar cut to size and attached by welding, which requires a large number of processing steps and has poor productivity.
There was a problem that the manufacturing cost was high.

Means for Solving the Problems As a means for solving the problems of the prior art, preferred embodiments of the vertical and horizontal tile holder according to this invention are shown in FIGS. 1 to 6 of the drawings. As shown, it has a pair of vertical and horizontal lower end support parts that support the front edge of the lower end of the tile, and a back support part that supports the upper back side of the tile, and is placed between approximately parallel horizontal frame members. A vertical beam is provided, and the back support portion is located approximately in the center of the vertical beam, and the lower end support portions for the vertical and horizontal portions are located at a distance necessary for leaning and supporting the tile in the longitudinal direction of the horizontal frame material. In a vertical and horizontal tile holder, which is provided with a pair of vertical and horizontal tile holders, (a) the vertical beams 12 have a wall thickness lower than the height dimension in the cross section of the horizontal frame material 11, and have the strength and rigidity necessary for supporting the tiles; It is formed into a plate shape with a width dimension. (b) A lower end support part 13 for horizontal use is provided in a protruding shape at the center of the vertical rung 12.

C. At the center of the same vertical tile 12, there is a plate-like overhang 1 with a width that maintains approximately the same wall thickness as the vertical tile 12 and has the strength and rigidity necessary to support the vertical tile B.
6 is provided to protrude in a direction parallel to the horizontal frame member 11, and a vertical lower end support portion 14 is provided in a protruding manner at the tip of the overhang portion 16.

D. The horizontal frame member 11, the vertical beam 12, the overhanging portion 16, and the vertical and horizontal lower end support portions 14, 13 are each integrally formed by casting.

E. Vertical lower end support part 14 and horizontal lower end support part 1
3, a concave portion a of a size that allows the front edge of the lower end of the horizontal tile A to come into contact with and be supported by the horizontal lower end support portion 13 is formed.

Function The horizontal tile A has its lower end directly attached to both horizontal frame members 11,
11 in a well-balanced manner, and at the same time insert it into the recess a, the front edge of the lower end is brought into contact with the horizontal lower end support part 13 to support it, and the back side is held by leaning against the back support part 15. can.

The vertical tile B also has its lower end directly attached to both horizontal frame members 11,
11 in a well-balanced manner, the front edge of its lower end is brought into contact with the vertical lower end support section 14 for support, and the back surface can be held against the back support section 15 in such a manner as to be supported.

Embodiment Next, the embodiment shown in FIGS. 1 to 5 will be described.

This example is a cast product made of heat-resistant cast steel.
are horizontal frame members arranged in parallel, 12,12'
13 is a horizontal lower end support part, 14 is a vertical lower end support part, and 15 is a back support part.

The horizontal frame member 11 has reinforcing ribs 11a with a total height of approximately 12 mm on the outer side of the upper surface in the cross section as a measure to ensure strength with a small amount of steel used (Figure 4).
is installed protrudingly. The vertical beam 12 has a wall thickness of approximately 6 mm, which is lower than the height (12 mm) of the reinforcing rib 11a of the horizontal frame member 11, and a width dimension to ensure sufficient strength and rigidity to support the tiles. It is said to have a wide flat plate shape of about 16 to 18 mm. Therefore, both horizontal frame members 1
The lower end of the tile placed on top of tiles 1 and 11 will not come into contact with vertical beam 12 (see Figure 3). Vertical beam 12
The horizontal lower end support part 13 has a width of about 40 mm and an overall height of about 22 mm at the center in the longitudinal direction, that is, at the almost center between the horizontal frame members 11, 11, and also in the center in the width direction. It is formed as a rib-shaped protrusion.

In addition, on both sides of the longitudinal center of the vertical rung 12 (however, only on one side for the vertical rungs 12' at both ends) are plates extending parallel to the horizontal frame members 11 with the same wall thickness of 6 mm as the vertical rungs 12. In order to obtain the necessary strength and rigidity to hold the roof tile B (Fig. 5) vertically, the overhang part 16 is made wide to about 10 mm, and a vertical lower end support part is provided. A vertical lower end support part 14 is formed at the tip of the overhang part 16 as a square prism-shaped projection with a side of about 10 mm and a total height of about 20 mm.

Thus, between the horizontal lower end support part 13 and the vertical lower end support part 14, there is a horizontal tile A (FIG. 5).
A recess a is formed in a size that allows the lower end to be placed directly on the horizontal frame members 11, 11, and the front edge of the lower end can be brought into contact with and supported by the horizontal lower end support part 13 ( (See Figure 3). By the way, concave part a
In this case, the distance between the horizontal and vertical lower end support parts 13 and 14 is about 24 mm, and the depth from the top surface of the horizontal frame material 11 is about 6 mm.
The size is about mm.

Therefore, the horizontal tile A has its lower end connected to the horizontal frame material 1.
1 and 11, and its lower end front edge is supported by the horizontal lower end support part 13, so that it is held upright. Therefore, the conventional auxiliary support part 7 (Fig. 7)
The actual height of the sideways tile A above the floor is lowered by the lack of a tile, which can cause accidents such as the tile hitting the low ceiling of the kiln and collapsing.
In addition, it is extremely useful for eliminating the problem of the lower tile being supported by the upper shelf of tiles stacked in two layers, and also eliminates all the problems caused by the conventional auxiliary support 7. Ru. In particular, the horizontal tile A is supported at a low point without the auxiliary support part 7.
The back support 15, which has the same height as before, is supported at a higher position, increasing the stability of the support state and reducing the rate of occurrence of distortion.

Further, the vertically oriented tile B (FIGS. 3 and 5) is also held upright with its lower edge placed directly on the horizontal frame members 11, 11 and its lower front edge supported by the lower end support portion 14.

Next, the back support part 15 is located between the horizontal tiles 12 and 12 or 12 and 12', and between the horizontal and horizontal lower end support parts 14 and 13, and the horizontal tiles A, They are provided at positions with appropriate intervals for holding each vertically oriented tile B upright.

Note that, particularly regarding the upper frame portion of each back support portion 15, a point-shaped fulcrum 15 is provided at the bent corner portion.
a, 15a are provided, and the plate width therebetween is formed to be slightly narrower. The significance of this fulcrum 15a is to enable the vertical and horizontal tile holder to be used in the following manner.

() The lower end of the Manjuken snow tile that is held horizontally is supported by the horizontal lower end support part 13, and the back part is only at the two fulcrums 15, 15 of the back support part 15. Leaning it back will keep the weight just right.

() When holding tiles for large sleeves or small sleeves vertically, the lower end of the tile is held at the vertical lower end support part 1.
Based on the curved state of the valley of the same tile, the back part is supported at two points, one fulcrum 15a of the back support part 15 and the center of the upper frame part of the back support part 15, to ensure a good weight balance. Retained.

() To hold a string or large-sided tiles vertically, the lower end of the tile is supported by the vertical lower end support part 14, and the back part is supported by the back support part 1.
By leaning only on the two fulcrums 15a and 15a of 5, it is possible to hold the weight with just the right balance.

Other Embodiments (Part 1) The back support portion 15 is not limited to the gate-shaped configuration shown in the illustrated example. It may simply be a columnar structure that stands upright on the horizontal frame member 11.

(Part 2) As shown in FIG. 6, all the vertical lower end supports 14 are provided only on one side of the vertical beam 12, and the tiles are held leaning against one side of the back support 15 only in the same direction. You can also do that.

(Part 3) Lower end support parts 14, 13 for vertical and horizontal use
Each of these can be implemented as a structure that abuts the tile at a point, or a structure that abuts and supports a somewhat long line or surface of an appropriate size.

Effects of the present invention As described above in detail together with the embodiments, the vertical and horizontal tile holder according to this invention has a structure in which the lower end of the horizontal tile A is placed directly on the horizontal frame material 11 and supported. Since the fulcrum on which the horizontal tile A is held or its actual height above the floor is lowered, there is a risk of the tile collapsing against the low ceiling wall of the kiln, or in a two-tiered kiln, the lower tile may collapse against the upper shelf. There is no risk that the product will be rejected due to being supported by it, and the yield will be improved. Not only that, but it is also possible to conversely reduce the size and capacity of the kiln to save energy in terms of heat.

Since the lower end of the tile is placed directly on the horizontal frame material 11 to hold it, there is no risk of defective tiles caused by carelessness or mistakes during the work of holding the tile, which was especially caused by the conventional auxiliary support. do not have. Also,
Since the width between the horizontal frame members 11 and 11 can be expanded relatively freely, it is possible to easily reduce the distortion occurrence rate of the tiles without reducing the absolute number of tiles held, and in this sense, the yield rate can also be reduced. and productivity will improve.

c○ Since the lower end of the horizontal tile A is placed directly on the horizontal frame material 11 and held, even if the height of the back support part 15 is the same as before, it supports a higher position of the tile A, and the tile The holding state is stable and contributes to reducing the strain occurrence rate.

d○ Since it is constructed using a casting method, it can be easily mass-produced even with complex shapes and structures, and the strength and rigidity of each part are uniform and high, ensuring consistent quality and a long service life. Therefore, overall cost reduction can be expected.
