Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame for fixing a base brick, which firmly fixes a base brick in a fixed shape as a bottom member on which a fired product is placed.

When putting a certain amount of so-called fired products (hereinafter referred to as fired products) into a kiln, such as bricks, pottery, tiles, roof tiles, etc., the kiln is constructed into a tunnel, the fired products are placed on a cart, and the cart is placed inside the kiln. It was being brought in.

By the way, sets of fired products, which are loaded onto carts, were prepared on the spot at a place called a trolley loading area, depending on the shape and size of the fired products to be loaded into the kiln.

In other words, the base brick (if you place the fired product directly on the trolley, the inside of the kiln will reach a high temperature of 1700°C to 1800°C, which will damage the trolley and prevent the fire from spreading to the fired product, so the bottom part called the brick is always placed). The necessary materials were brought from the stand brick storage area (for placing the wood and the fired materials on top of the materials), and the necessary items for the fired materials were brought from the goods storage area and stacked in an appropriate shape.

Of course, in this case, a lift or the like is used to transport the bricks from the stand brick yard or the goods storage area, but since these are simply carried on pallets, they often fall and get damaged during transportation. It was about.

Furthermore, the same applies when removing the fired product from the kiln.

Therefore, the present invention solves the above-mentioned problems by providing a frame that holds and fixes the base bricks in a fixed shape.

Examples of the present invention will be described below with reference to the drawings.
In the accompanying drawings, Figure 1 is a perspective view of the frame, Figures 2 and 3 are plan views showing the case where the frame is wrapped around the base bricks, and Figure 4 is a diagram showing how the base bricks are assembled. 5 is a partially sectional front view showing the case where the frame is placed on a trolley, FIG. 6 is a partially sectional side view, and FIG. 7 is a partially sectional plan view.
The figure is a partially sectional front view of main parts showing another implementation row.

Frame 1 is made of iron plate material, wood, etc., and in its completed state,
It is rectangular in plan view.

This frame 1 can be wrapped around a rectangular base brick 3 formed by assembling brick pieces 2. To do this, a hinge structure 4 is provided at the bending point of the frame 1. (A commercially available hinge may be used.) In this respect, it is made to be flexible and to be able to be wrapped around the base brick 3.

Then, when wrapping it around the base brick 3, in order to securely fix it, for example, the - side of the frame 1 is divided into two (
(see Fig. 2), flanges 5, 5 are formed at this parting point, and holes 6, 6 are passed through each flange 5, 5 (see Fig. 1), while threaded rods 7 are inserted into these holes 6, 6.
A fastening structure 9 is provided, such as inserting the 7 flange 5, 50 and tightening it with nuts 8, 8 from both ends of the 7 flange 5, 50 (see Fig. 5).

In addition, as for the wrapping method, it is also possible to use a separate type in which the frame 1 is divided on both the upper and lower sides, and to wrap the frame 1 side by side from the left and right sides (see Fig. 3).

There are various shapes in which the base bricks 3 are assembled, but in any case, the brick pieces 2 are assembled vertically and horizontally to form a rectangular shape as a whole in plan view.

At this time, the uneven shapes 10 are applied to the brick pieces 2, and these uneven shapes 10...
If a structure is adopted in which the ... are interlocked with each other (see Figure 4), this assembly will be strong.

By the way, this frame 1K has a contact part 1a that comes into contact with the base brick 3 on the upper part of its inner circumferential surface, and a band-shaped projection part 1b that projects inward from the frame 1 from below this contact part 1a. do.

Note that the band-like projection 1b is located at the vertical center of the inner circumferential surface of the frame 1, and below this, a lower wall 1c exists.

Further, a cushioning material 11 such as rubber may be attached to the surface of the abutting portion 1a.

In addition, lifting means 12 such as hanging rings are provided at the top and bottom near the left and right ends of the outer peripheral surface of the frame 1, and lift forks are provided at the top and bottom of the lower end of the center side of the lower wall 1c. A cutout 13 into which the can be inserted is formed in advance.

In addition, the upper end of this notch 13 must be located slightly below where the bottom surface is located so that it will not interfere with the base brick 3 etc. even if the fork is inserted. No.

The purpose of fixing the base brick 3 using the frame 1 described above is to first open the hinge structure 4 and wrap it from the outside of the base brick 3, so that the band-like protrusion 1b touches the bottom surface of the base brick 3. The vicinity of the periphery is scooped up from below, and the top surface is brought close to the bottom surface of the base brick 3. The fastening structure 9 is operated to press it.

Note that the lower wall portion 1c below the band-shaped protrusion 1b has one place in the center (in some cases, in contrast to this, two or more places,
Insertion holes 14 are formed to pass through the left and right lower walls 1c, 1c (in multiple locations).
The support rods 15... can be inserted through them.

This support rod 15... is inserted through the hole 14...
By inserting it through the base brick 3, the bottom surface of the base brick 3 is supported.

By the way, strictly speaking, the support rods 15 are located below the band-shaped projection 1b, so the bottom surface of the base brick 3 placed on the top surface of the band-shaped projection 1b is not supported. Although it does not come into contact with the rods 15, the center part of the base brick 3 sags due to its weight, so in reality, the base brick 3 is also supported by the support rods 15. This is what happens.

Therefore, the base brick 3 is affected by the frictional force due to the suppression of the abutting portion 1a of the frame 1, the band-like protrusion portion 1b and the support rod 15...
... is integrated with the frame 1 by support from below (see Figures 5 and 6).

If necessary, the support rod 15 and the frame 1 can be fixed more easily by forming screws on both ends of the support rod 15 and tightening them by screwing nuts 16, 16 from the outside of the frame 1. It becomes stronger (see Figure T).

Further, the shape of the band-shaped protrusion 1b may be formed not only in a simple straight line but also in a slope that rises slightly (approximately 2 degrees) from the center to both ends (see FIG. 6).

Next, once the base brick 3 is fixed using the frame 1 in this way, it is transported and placed on a trolley 17 that can be accessed by the tunnel kiln.

That is, paving bricks 18 are laid in advance in about three rows in the vertical direction on the trolley 179, and these paving bricks 18...
The base brick 3, which is integrated with the frame 1, is placed on top of...

The reason why the paving bricks 18...
This is to create a gap between the base and the bottom of the fire to improve the circulation of the fire.

By the way, when placing the base brick 3 on top of the paving bricks 18...
Since it must not interfere with..., the paving brick 18...
The laying shape of ... must also be smaller than the rectangle formed by the tip of the band-like protrusion 1b.

In other words, since it is normal for the base brick 3 to protrude 3 to 4 cm from the surroundings of the paving bricks 18, the amount of protrusion from the inside of the band-like projection 1b must also be made smaller than the knead. There must be.

In this way, when placing the base brick 3 integrated with the frame 1 on top of the paving bricks 18 so that their centers coincide with each other, the shape of the frame 1, that is, the support rod 1
5... and the existence of the fastening structure 9 will be the goal.

When laying the paving bricks 18..., baking powder 19 (pulverized fired material) is spread on the cart 17, and the paving bricks 18... are placed on top of this. <In this way, stability will be improved.

Furthermore, when using the baked powder 19 with the band-shaped protrusion 1b formed on a slope, the bottom surface of the base brick 3 is also shaped to be sloped along this slope, so it is natural that the base brick 18 The upper surface of the bricks 18 must also match this, but in this case, by adjusting the amount of spreading, the paving bricks 18 can be laid on a slope.

As described above, the base brick 3 has been set on the trolley 17, and the next step is to stack the fired products 20 on the base brick 3 in an appropriate shape, move the trolley 17, and transport them into the kiln. .

In addition. Since the base brick 3 is firmly fixed by the frame 1, the fired product 20 is placed on the base brick 3 before being transported to the trolley 17, and the fired product 20 is placed on the base brick. 3
It may also be possible to transport the

When carrying the cart 17 into the kiln, this frame 1 is removed.

That is, first, remove the support rod 15...
Next, the fastening structure 9 is removed and the entire frame 1 is removed.

Similarly, when it is baked and taken out of the kiln,
If the frame 1 is attached again in the reverse order, the base bricks 3 are firmly fixed and can be transported as they are.

As described above, in this invention, by fixing the base bricks 3 using the frame 1, the base bricks 3 can be firmly integrated in the shaped shape, and can be moved by a lift or the like. Even when carrying it around, there is no risk of it falling partially or completely and breaking.

At this time, the fact that the base brick 3 is firmly integrated means that it can be transported with various fired products 20 placed on it, so the base brick 3 and the fired product 20 can be transported while being placed on it.
It becomes possible to carry the device in its set state, improving workability, safety, cost, etc.

Furthermore, by storing the base brick 3 after use while it is fixed in the frame 1, it is possible to separate the individual brick pieces 2 and 3 as in the conventional method.
Compared to bricks that are disassembled and left in a brickyard, there is no damage caused by this, and it takes less time and effort to reset them, and they can be stacked in several tiers. It can be stored neatly and saves storage space.

Moreover, in the conventional case, the brick pieces 2 constituting the base brick 3...
If even one of them were broken, it would have been necessary to replace it with a new one and reassemble it again, but according to this invention, the base bricks 3 are firmly bound by the frame 1. Even if there are broken brick pieces 2 mixed in, it can be used as is (many broken surfaces have a so-called zigzag shape, so this effect is even more ).

Furthermore, by forming the band-shaped protrusion 1b of the frame 1 with an upward slope from the center on both sides, the base brick 3 also follows this slope,
Since the fired products 20 stacked on top of the stack are inevitably centered in a so-called pyramid shape (see FIG. 6), the shape is more stable and there is no damage caused by the load collapsing during transportation.

In addition, if the frame 1 is provided with a lifting means 12 such as a hanging ring or a notch 13 for inserting a fork, it will be easier to use a crane or fork, making transportation easier. It becomes convenient.

According to calculations made by the inventors, it has been confirmed that by implementing this invention, a reduction effect of several tens of times can be expected in terms of both labor and materials.
