[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved beam support seat used for connecting beams for a ceramic product firing shelf assembly on or above a support. The beam support seat of the present invention can be suitably used for a ceramic product firing furnace that is assembled using beams, such as a sanitary ware firing furnace and an interior / exterior tile firing furnace.

[0002]

2. Description of the Related Art A conventional shelf for firing ceramic products is, for example,
As shown in FIG. 6 and FIG.
A joined body 9 composed of an engaging portion 7 having a square cross section which is erected and engaged with an inner peripheral surface of an upper portion of a rod-shaped support 11 and a girder receiving portion 8 having a U-shaped cross section provided horizontally above the engaging portion 7. Are fitted, a bar-shaped girder (beam) 4 is laid horizontally between the girder receiving portions 8 of two opposing joints 9, and a shelf 10 is placed on the beam 4. .

[0003] Beams used in shelves for firing ceramic products are repeatedly used at high temperatures, resulting in deformation and twisting during use. When the beam is deformed or twisted, the load is evenly and uniformly supported, and the beam is easily broken. In addition, the deformed or twisted portion causes the load to rattle. Therefore, in order to prevent such a situation from occurring, the shelves must be assembled after correcting and adjusting the deformation and twist of the beam. In particular, adjustment is troublesome and difficult at a joint between two beams having different degrees of deformation.

[0004] Therefore, in recent years, a pillar having a hole in which a rod-shaped pillar is made thick and provided with a beam insertion hole has been used, and a cushioning material is packed on a beam mounting surface of the hole. It has become For example, as shown in FIGS. 8 and 9, when two beams 4 and 4 ′ are connected in a hole of a holed support 5, the beam 4 and 4 ′ are connected between the holed support 5 and the beams 4 and 4 ′. Packing of fiber 6 and the like is performed. Also,
As shown in FIGS. 10 and 11, even when the beams 4 and 4 'are placed on the upper surface of the column 1 and connected, a method such as packing a fiber 6 or the like between the column 1 and the beams 4 and 4' is used. Is adjusted and shelves are assembled.

[0005]

However, in each of these conventional methods, since the adjustment of the beam on the upper surface of the support or in the support is performed by ceramic fiber or the like, one beam is adjusted in accordance with the degree of deformation of each beam. It has to be adjusted every time, it is troublesome, and there is a problem that the ceramic fiber is deteriorated by long-time use and needs to be readjusted.

[0006]

Therefore, the present inventor has made various studies in view of the above-mentioned conventional problems, and found that this problem can be solved by using a beam support seat having a specific shape. The present invention has been reached.

That is, according to the present invention, a beam supporting seat used for connecting a beam for assembling a ceramic product firing shelf assembly on the upper surface of a support or in a support, and is substantially a semi-cylindrical body having a semicircular cross section. A beam support seat, characterized in that the gutter-shaped groove or lower part provided in the upper surface of the support or the support is fitted in a gutter-shaped hole to support the beam,
Is provided.

In the present invention, it is preferable that the beam supporting seats are installed so as to support each beam on the upper surface of the column or in the column.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a beam supporting seat used for connecting a ceramic product firing shelf assembling beam on the upper surface of a pillar or in a pillar, and the beam supporting seat is substantially a semicircular cylinder having a semicircular cross section. Its characteristic is that it is formed by the body.

[0010] By using such a beam support seat, the support seat can be rotated and moved in accordance with the degree of deformation of each beam to be connected, and the positional deviation due to the beam deformation can be easily adjusted. it can.

The beam support seat 3 of the present invention is shown in FIGS.
As shown in the figure, a semi-cylindrical body having a substantially semicircular cross section,
The gutter-shaped groove 2a or the lower part provided in the upper surface of the column 1 or the holed column 5 is fitted into the gutter-shaped hole 2b, and the beam 4
It is to support.

Therefore, when the beam 4 is deformed, the beam supporting seat 3 is rotated in the gutter-shaped groove 2a or the hole 2b as shown by an arrow (see FIG. 1), so that the beam 4 can be easily moved by the beam deformation. The deviation can be adjusted. As the material of the beam support seat in the present invention, it is necessary to use the same fire-resistant material as that of the columns and shelves in accordance with the type of the object to be fired and the firing conditions.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to illustrated examples, but the present invention is not limited to these illustrated examples. FIG. 2 is a schematic cross-sectional view showing an example of a case where the beam support seat of the present invention is mounted on the upper surface of the column and the beams are connected.
FIG.

2 and 3, a gutter-like groove 2a is provided on the upper surface of the column 1 and beam support seats 3 and 3 'are installed in the gutter-like groove 2a. 4 'is placed. In this case, even if the two beams 4, 4 'are deformed or twisted, the two beam support seats 3, 3' are rotated and moved as shown by arrows in FIG. This makes it possible to easily adjust the deviation between the two beams 4, 4 '.

Since the beam support seats 3 and 3 'are provided on the upper surface of the column 1 so as to support the two beams 4 and 4', respectively, the beam support seats 3 and 3 'correspond to the degree of deformation of each beam. Adjustments are possible. FIG. 4 is a schematic cross-sectional view showing an example in which the beam support seat of the present invention is installed in a column with holes and a beam is connected, and FIG. 5 is a schematic vertical cross-sectional view of the same.

In FIGS. 4 and 5, a hole 2b is
And beam support seats 3, 3 'are installed in the holes 2b,
The two beams 4, 4 'to be connected are mounted thereon. Also in this case, the displacement between the two beams 4 and 4 'can be easily adjusted in the same manner as in the examples of FIGS.

[0017]

As described above, according to the beam support seat of the present invention, the beam support seat is composed of a semi-cylindrical body having a substantially semicircular cross-section and is provided with a gutter-like groove or lower portion provided in the upper surface of the support or in the support. Is fitted in a gutter-shaped hole to support the beam, so that the beam support seat is rotated according to the degree of deformation of each of the two beams to be connected,
It is possible to easily adjust the positional deviation due to the deformation and twist of the beam.
