Description

[Detailed explanation of the invention] This invention is an L-shaped accessory tile with joints of 50 mm.
This invention relates to the improvement of a sagger used when firing equilateral curved ornamental tiles (hereinafter referred to as equilateral tiles 1) such as 90° corner curves, acute angle curves, and 90° water cutting curves.

The present applicant has filed Utility Application No. 56-50268 (Utility Model Application No. 57-
169996), a protrusion of the same shape, that is, an inverted V-shape, is formed on both sides of the sagger main body 2, which has a bending angle α of 90° and is formed into an inverted V-shaped cross section with equal sides, as shown in Fig. 1. A sagger 4 is proposed in which the frames 3 and 3' are integrally connected to the sagger body 2, and a reinforcing protrusion frame 3a having the same shape as the protrusion frames 3 and 3' is integrally provided approximately in the center of the sagger body 2. did. The method of using the saggers 4 is to place the raw material of the equilateral tiles 1 on the back surface 5 of each sagger main body 2 with the surface facing upward, and then stack several saggers 4 on a cart one after another and fire them. However, when the number of stacked saggers 4 is increased, there is a risk that the stacked saggers 4 may tilt in one direction and lose stability due to the vibrations and shocks of the trolley being transported within the kiln, causing them to fall.

The present invention has been devised in view of the above drawbacks, and will be described below based on one embodiment. The sagger for firing equilaterally curved accessory tiles according to the present invention (hereinafter referred to as sagger 6) is a 90° curved equilateral tile 1 (hereinafter referred to as 90° curved equilateral tile 1a) shown in FIG.
As shown in Fig. 3, the sagger body 2 has a bending angle α of 90° and has an inverted V-shaped cross section with equal sides.
A sagger body 7 formed integrally with two pieces 2' arranged in parallel.
, protruding frames 8, 8' formed integrally with the sagger body 7 on one side thereof at both hem edges of the inverted V-shaped sides of the sagger bodies 2, 2', and approximately at the center of one side of the sagger body 7. A reinforcing protrusion frame 9 is integrally formed with the protrusion frames 8 and 8' and has the same shape.
It consists of As shown in FIG. 4, the saggers 6 are stacked by interlocking the back surfaces 10, 10' of the saggers 6 with the protruding frames 8, 8' and the reinforcing protruding frames 9, so that the protruding frames 8, 8' and The bending angles β and γ of the reinforcing protrusion frame 9 are both equal to the bending angle α of the sagger bodies 2 and 2', which is 90 degrees. 2' back side 5,
The heights h1, h2, h3 from 5' must all be equal and greater than the thickness of the 90° curved equilateral tile 1a. The sagger 6 is 90 degrees above the back 5, 5' as shown in Figure 4.
After the .degree.-curved equilateral tiles 1a are placed with their surfaces facing upward, they are sequentially stacked on a cart (not shown) and transferred to the firing process. The reinforcing protrusion frame 9 serves to prevent the sagger body 7 from bending when the sagger 6 is used repeatedly, and an appropriate number of reinforcing protrusions are provided if the sagger body 7 is horizontally elongated. In addition, in the sagger 6 in Fig. 3, the sagger body 2, 2'
Although two pieces are formed in parallel in one piece, it is also possible to form three or several pieces in parallel in one piece if necessary. 90° curved equilateral tile 1 as equilateral tile 1
In addition to a, when firing equilateral tiles 1 with acute angle curves or obtuse angle curves, the bending angles α, β, and γ of the sagger bodies 2 and 2', the protrusion frames 8 and 8', and the reinforcing protrusion frames 9 are set at the same time. It is necessary to make these acute angles and obtuse angles equal.

As another embodiment of the sagger 6, as shown in FIG.
2, 13 can be made smaller than the width W of the back surface 5, 5' of the sagger body 2, 2', and the lengths 11, 12,
There is no need to make both 13 and 13 equal. Furthermore, the left and right movement of the saggers 6, which are stacked in large numbers, is restricted, but
In order to restrict the movement of the other side in the front-back direction, an appropriate small protrusion is provided on the upper surface of the protrusion frames 8, 8' or the reinforcing protrusion frame 9, and at the same time, a small concave portion into which the small protrusion fits is inserted into the sagger body 7. It may be provided opposite to the back surfaces 10, 10' of. In addition, as shown in FIG.
5' and the back surface 10, 10', and the protruding frame 8
a, 8'a, 8b, 8'b and reinforcing protrusion frame 9a,
9b, and their heights h1' and h1'', h
It is also possible to make the sum of 2' and h2'' and h3' and h3'' equal to the heights h1, h2, and h3 shown in FIG. 3.

The sagger according to the present invention is formed by arranging two or more rows of sagger bodies in parallel and has a large ground contact area, so even if the sagger is stacked in multiple stages on a cart, it remains stable and does not tilt to the left or right. It can be transported stably without falling over due to vibration or impact, and when stacking saggers on a trolley, it is possible to load two saggers at a time compared to conventional saggers. Work efficiency improves.

Claims (1)

[Scope of utility model registration request] A sagger body is formed by integrally forming an appropriate number of sagger bodies with an equilateral inverted V-shaped cross section in parallel, and a sagger body is formed on one side of the sagger body at both side edges of the inverted V-shaped side of the sagger body. It is composed of an integrally formed protrusion frame and a reinforcing protrusion frame that is integrally formed with the sagger body between the protrusion frames, and the protrusion frame and the reinforcing protrusion frame have a bending angle equal to that of the sagger body. The sagger for firing equilaterally curved ornamental tiles is further characterized in that the heights of the protruding frame and the reinforcing protruding frame from the back of the main body of the sagger are both equal and greater than the thickness of the equilaterally curved ornamental tile.
