Description

[Detailed Description of the Invention] This invention relates to a firing jig for holding white tiles, especially eaves tiles, vertically on a cart (kiln car), etc. during drying and firing.

BACKGROUND TECHNOLOGY When loading white tiles into a firing furnace, the orientation is vertical (the center line of the valley is vertical) depending on the type of tile or the state of glaze application.

) or sideways (the center line of the valley is horizontal).

) and hold it in a firing jig. By the way, when the eaves tiles are held vertically, it is necessary to hold them at a sufficient distance to prevent adhesion or uneven firing of the wide hanging parts.

For this reason, the pitch between the held roof tiles becomes large.

As a result, the firing jig holds only a small number of roof tiles, resulting in poor efficiency.

As a result, the number of tiles that can be charged into the firing furnace is reduced, resulting in a reduction in the productivity of the tiles.

Purpose of the invention Therefore, the purpose of this invention is to be able to efficiently hold a large number of tiles, especially eaves tiles and dead objects, at as small a pitch as possible without being obstructed by their sagging, and thus To provide a tile firing jig with an improved structure capable of increasing the number of tiles that can be charged into a tile and improving productivity of tiles.

Structure and Effects of the Invention In order to achieve the above object, the baking jig of this invention consists of two parallel frames made of steel rods, etc., which are fixed to each other at a constant interval in the longitudinal direction. A plurality of support members for the upper part of the tile, and a support part for the lower part of the tile fixed to the frame at an intermediate position between adjacent support members or at an end position in the longitudinal direction of the frame as necessary. There is.

Moreover, the support member for the upper part of the tile is formed by processing a steel plate of a required width, and the support part for the lower part of the tile has a locking member that is L-shaped when viewed from the front and is arranged symmetrically on the frame. Further, the vertical portion is fixed in a vertical position, and a protrusion is provided adjacent to the vertical portion of the locking member and is taller than the vertical portion.

In other words, the white eaves tiles are made of steel plates of a predetermined width, each oriented vertically, with support members for the upper part of the tiles placed between them, leaning against both sides, and each tile is held in such a way that its sag faces each other. .

Moreover, the lower end of the tile on one side rests on the upper end of the vertical portion of the locking member, and the front edge is held high with the front edge abutting against the protrusion.

The tile at the other end is held low with its lower end placed directly on the frame and its front edge abutting against the vertical or horizontal end of the locking member.

Therefore, the sag of each tile is staggered due to the difference in height at which each tile is held, and they do not interfere with or come into contact with each other.

Therefore, the spacing between tiles can be reduced to the smallest possible pitch, and a large number of tiles can be held efficiently.

Furthermore, it is possible to increase the number of tiles that can be charged into the kiln and improve the productivity of tiles.

The holding interval (pitch) between roof tiles can be properly defined as the width dimension of the top support member formed of a steel plate.

In addition, with the tile facing sideways, the lower end is placed on the horizontal part of the locking member, and the front edge is supported against the vertical part or protrusion of the locking member, and the roof tile is placed on the upper support member. The prop can also be held.

Next, the illustrated embodiment will be explained.

1st Embodiment In FIGS. 1 to 3, numeral 3 indicates the entire firing jig.

In the figure, 4 and 4 are two parallel frames, each with a length of 48
It is made of a heat-resistant steel rod with a diameter of about 12 mm and a diameter of about 12 φ.

In the figure, reference numeral 5... is a support member at the top, which is placed across the frames 4, 4 at equal intervals of about 16 cm in the longitudinal direction of the frames 4, 4, and is in contact with the frames 4, 4. The parts are fixed by welding.

As shown in FIG. 3, the support member 5 is made by bending a heat-resistant steel plate with a width of about 54 mm into a symmetrical trapezoid shape with a height of 13 cm and a top width of about 10 cm, and a drawing process 6 for reinforcement. , and its lower ends are joined to the frames 4, 4 by welding.

In the figure, numerals 8, 12, and 13 are protrusions, locking members, and auxiliary members that form the support portion of the lower part of the tile.

These are provided fixedly attached to the frames 4, 4, respectively, at substantially intermediate positions between the support members 5 on the upper side.

The locking member 12.12 is made of a heat-resistant steel rod with a diameter of about 12φ.
The length of the horizontal part 12a is approximately 56 mm, and the height of the vertical part 12b is 3
It has a bent L-shape of about 5 mm.

This locking member 12 is arranged symmetrically on the two frames 4, 4 at a position where the horizontal distance W1 from the end face of the horizontal portion 12a to the front edge of the upper support member 5 is approximately 42 mm. The bodies 4, 4 are stacked in the same direction in the longitudinal direction, and the vertical portion 12a
is fixed by welding so that it stands upright.

The auxiliary member 13 is a heat-resistant steel rod with a diameter of about 12φ and a length of about 23 m.
It is cut into a length of approximately m, its upper end is aligned with the upper end surface of the vertical portion 12b, and is integrally fixed along the vertical portion 12b.

The protruding portion 8 is formed as a bent portion formed by vertically bending both ends of a connecting frame 7 which extends inside the two frames 4, 4 and whose abutting portions are fixed by welding.

However, the protrusion 8 may be provided as an independent member separate from the connection frame 7.

The connecting frame 7 is made of a heat-resistant steel rod with a diameter of about 9φ, and has a protrusion 8.
is formed as a bent portion with a height of about 65 mm.

The protrusion 8 is approximately 8 mm taller than the upper end of the vertical portion 12b.

The protrusions 8, 8 are connected to the horizontal portion 12 of the locking member 12.
It is located approximately in the center of a.

That is, the horizontal distance W2 from the side surface of the protrusion 8 to the front edge of the support member 5 is approximately 42 mm.

Therefore, when the support part of the lower part of the tile constructed in this manner is viewed from the front in FIG. 2, it forms a dovetail shape.

That is, the horizontal distance W1. There are two types of W2, and the height from the support point at the bottom of the tile to the top front edge of the upper support member 5 is Hl.

It is different from H2 in two types.

Next, reference numeral 12' in the figure is a locking member fixed to the left end portion of the two frames 4, 4 in FIG.

Reference numeral 12'' denotes a locking portion bent at the right end of the frame 4.4 and corresponding to the end surface of the horizontal portion 12a of the locking member 12.

In the figure, reference numeral 13' denotes an auxiliary member fixed to the left end of the frames 4, 4 in FIG.

Therefore, with respect to the above-mentioned firing jig, the tiles 15 oriented vertically are as follows:
The lower part B is placed on the upper end of the vertical part 12b of the locking member 12, the lower front edge A of the tile is brought into contact with the protrusion 8, and the approximately central part of the back is brought into contact with the top left front edge C of the upper support member 5. They are held upright so that they are touching each other.

In addition, the lower part B of the tile 16, which is also oriented vertically, is placed on the frames 4, 4, and the front edge A of the lower part of the tile is the left end surface of the horizontal part 12a of the locking member 12 (or the locking part 12''). , and the approximate center of the back surface is the top right front edge C of the upper support member 5.
It is held upright so that it is in contact with the

In other words, the two roof tiles 15 and 16 are propped up on both sides of a common upper support member 5 with their respective hangings 15 a and 16 a facing each other.

The vertical portion 12b of the locking member 12 and the frame body 4 are held at different levels by a height difference (approximately 35 mm).

Therefore, the two roof tiles 15 and 16 have their respective sag 15a and 16
A distance S sufficient to prevent adhesion or uneven baking is maintained between the two sheets a.

In this way, the hangings 15a and 16a can be alternately wrapped, and the pitch between the two roof tiles 15 and 16 can be reduced, so the number of tiles that can be held can be increased as much as possible.

In addition, with respect to the above-mentioned firing jig, the tile 15', which is oriented vertically, is
The lower part B is placed directly on the frame 4, and the front edge A of the lower part of the same page is placed on the left end of the horizontal part 12b of the locking member 12 (or the locking member 12'
), and can also be held upright so that the substantially central portion of the rear surface abuts the top left front edge C of the top support member 5.

Alternatively, the lower part B of the tile 18 placed horizontally is placed on the horizontal part 12b of the locking member 12, the lower front edge A of the same page is brought into contact with the auxiliary member 13, and the approximately central part of the back side is viewed from the upper support member 5. It can also be held leaning against the right front edge C of the top.

Second Embodiment Most of the construction of the firing jig 3' shown in FIG. 4 is the same as that of the first embodiment.

Therefore, they are expressed using common symbols.

However, in the case of this embodiment, the top of the support member 5 on the upper side is
It is characterized by being formed by fixing a steel plate 14 having a predetermined width e.

In other words, the parts other than the steel plate 14 are formed of steel plates with the minimum necessary width, thereby achieving the objectives of saving the amount of materials used, reducing costs, and reducing weight.

Therefore, the manner in which the tiles are held by this firing jig and the effects achieved are basically the same as those of the first embodiment.
