Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a firing jig for a plate-shaped object to be fired, such as a concrete panel.

[Background Art] Conventionally, an object to be fired 1 such as a concrete panel has been fired by placing it horizontally on a firing jig A' formed by stacking firebricks 14 as shown in FIG. When the object 1 to be fired is glazed, there is a problem in that dust and the like adhere to the glazed surface, making it impossible to obtain a good glaze. For this reason,
As shown in FIG. 6, the object to be fired 1 is held vertically on a cart 15 for firing, but in this case, the object to be fired 1 may warp due to its own weight. I had done it. Therefore, as shown in FIG. 8, the present inventors have already attached a mounting member 5 with an inclined upper surface to a structure 7 made of refractory material, erected a support 10, and attached a support 3 to the support 10. A firing jig A'' installed at a predetermined angle is devised, the object to be fired 1 is placed vertically at an angle, the inclined side surface 2 of the object to be fired 1 is supported by the supporting member 3, and the lower end surface 4 is By firing with the glaze held on the upper surface of the mounting material 5, the object 1 to be fired will not warp, and even if the glaze is applied to the object 1 to be fired, dust will not adhere to the glazed surface. However, when the inclination angle θ of the object to be fired 1 with respect to the vertical plane became a high angle of 13 degrees or less, the object to be fired 1 almost touched the lower end surface 4 of the mounting material 5. Therefore, warping due to its own weight occurred.

[Purpose of the invention] The present invention was made in view of the above circumstances, and its purpose is to provide a baking jig for vertically placing the object to be baked at an angle, and the inclination angle is high. To provide a firing jig that does not cause warping of a fired object due to its own weight even after aging.

[Disclosure of the invention] The firing jig of the present invention is a firing jig for vertically placing a plate-shaped object 1 to be fired at an angle.
A support member 3 supporting the inclined side surface 2 of the burner is erected, and a protrusion 6 is provided protruding over the entire length in the longitudinal direction on the upper surface of the mounting member 5 supporting the lower end surface 4 of the object to be fired 1. With this configuration, the above objective could be achieved. That is, even when the object to be fired 1 is tilted at a high angle and placed vertically, the lower end surface of the object to be fired 1 is supported by the mounting member 5 via the protrusion 6.
This is a so-called line support, and therefore, the object to be fired 1 is supported by the support material 3 even on the inclined side surface 2, so that warping due to its own weight will not occur.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The structure 7 to which the supporting material 3 and the mounting material 5 are attached is made up of two vertical members 8 made of refractory bricks covered with stainless steel plates placed at predetermined intervals, each of which is covered with a stainless steel plate. A horizontal bar 9 of books is stretched across the structure 7, and a plurality of columns 10 are erected in the longitudinal direction of the structure 7. A horizontal bar 11 is provided between the upper ends of the columns 10. There is a support bar 12 between the lower parts.
is being passed over. A long mounting member 5 made of a refractory material such as firebrick is attached to the upper surface of the vertical member 8 of the structure 7, and the upper surface of this mounting member 5 is oriented downward as it goes inward. A rod-shaped body such as a steel material is embedded in the outer side of the upper surface 5a, and a protrusion 6 is provided extending along the entire length of the upper surface in the longitudinal direction. Slanted surface 5a of mounting material 5
A plurality of supports 3 made of refractory bricks with iron bars embedded therein at predetermined intervals in the longitudinal direction are propped up against the support members 3, the upper ends of which are fitted between a pair of angles 13 on the sides of the horizontal bar 11, and the lower ends of the support members 3 are Support bar 1
2, and is mounted inclined at a predetermined angle θ. This angle is less than 13°.

According to this baking jig A, the lower end surface 4 of a plate-shaped object to be baked 1 such as a concrete panel is placed on the inclined surface 5a of the mounting material 5 of the baking jig A placed on a trolley, The inclined side surface 2 on the inner surface side is supported by the support member 3 and held vertically in an inclined state, and in this state, the firing jig A is carried into the firing furnace by a trolley and the object 1 to be fired is fired. The object to be fired 1 can be fired without warping.

[Effects of the invention] With the present invention, the plate-shaped object to be fired can be placed vertically at an angle, so even when glaze is applied to the object to be fired, there is no dust adhering to the glazed surface, making it easy to use. Of course, it is possible to obtain a beautiful glaze by erecting a support member that supports the inclined side surface of the object to be fired, and placing a support member that supports the lower end surface of the object to be fired over the entire length in the longitudinal direction. Since the protrusions are provided, even when the object to be fired is tilted at a high angle and placed vertically, the lower end surface of the object to be fired will be supported by the mounting material via the projections. This is a so-called line support, and therefore, the object to be fired is supported by the support material even on the inclined side surface, and warping due to its own weight does not occur.
