Description

  The present invention relates to a support structure for supporting a checker brick of a hot stove and a deflection block used therefor.

  A hot blast furnace is attached to the blast furnace for ironmaking. A checker brick for heat storage is laminated inside the hot stove. As a structure for stacking checker bricks, there is a stack structure in which checker bricks in each layer are individually connected (chimney stack, see Patent Document 1). Furthermore, a laminated structure (lap stacking or ABC stacking, see Patent Document 2) in which checker bricks of each layer are sequentially shifted is used so that the brick joints of each layer are not aligned.

A duct for circulating air through the checker brick is connected to the lower side surface of the hot stove. Moreover, the metal receiving material for supporting a checker brick is installed in the bottom face of a hot stove.
In the conventional receiving metal, a metal support is placed on the bottom of the hot stove, and a steel horizontal beam is supported by this support, and an opening similar to the checker brick through hole is provided on the upper surface of the horizontal beam. It is formed by stretching a thick metal plate. The checker brick is received on the upper surface side of the receiving plate. A ventilation space is formed between the support columns on the lower surface side of the receiving plate. The ventilation space communicates with the duct described above.

When storing heat in the hot air furnace, the hot air that has heated the checker brick is ejected downward from the through hole of the lowermost checker brick, gathers in the ventilation space, and is then discharged from the duct to the outside.
When supplying hot air to the blast furnace, outside air is introduced into the ventilation space from the duct, and is distributed to each through hole of the checker brick, heated while passing through the checker brick, and sent to the blast furnace as hot air.

By the way, in the hot stove mentioned above, the blast furnace gas (BFG) discharged | emitted from a blast furnace is utilized as fuel gas at the time of storing heat to a checker brick. However, BFG alone is not sufficient in the amount of heat as a heat source for the hot stove. For this reason, the BFG is heated (preheated) by reusing the exhaust heat of the hot stove itself. Further, not only BFG but also coke oven gas (COG), converter gas (LDG), and the like are supplementarily mixed as fuel gas for the hot stove to compensate for the amount of heat.
However, COG, LDG, and the like that are used supplementarily are generally more expensive than BFG, and it is desirable not to use them as much as possible. Therefore, it is desirable to expand the preheating of BFG.

On the other hand, in the blast furnace supplied with hot air from the hot air furnace described above, oxygen is blown into the blast furnace together with hot air from the hot air furnace as necessary, for example, when the temperature or heat quantity of the hot air from the hot air furnace is insufficient. It has been made up for.
However, when oxygen is blown into the blast furnace to supplement the amount of heat in the blast furnace, the operating cost for purifying the blown oxygen increases. It is desirable that the hot air supplied from the hot blast furnace to a blast furnace be sufficiently high so that the amount of heat can be supplemented while avoiding such an increase in operating costs.

Japanese Patent No. 4216777 Utility Model Registration No. 2563087

As described above, in order to change the hot air supplied from the hot stove to the blast furnace to a high temperature hot air having a sufficient amount of heat, the amount of heat stored in the checker brick of the hot stove is increased, and the temperature of the checker brick, particularly the bottom surface It is necessary to increase the temperature.
However, in the above-described conventional receiving metal, the support and the horizontal beam are made of steel, and the heat resistant temperature is about 350 ° C., and cannot be used at a higher temperature.
Due to the limitation of the temperature condition of the metal receiving piece, the following problems have occurred in the conventional hot stove.

When supplying hot air to the blast furnace, the upper limit of the heat storage energy is restricted by the hot air for heating during heat storage being restricted to 350 ° C or less at the receiving metal part. As a result, sufficient hot air is supplied to the blast furnace. High temperature cannot be achieved.
For this reason, in the blast furnace, auxiliary oxygen injection is unavoidable, and the operating cost cannot be suppressed.

On the other hand, when storing heat in the hot stove, the temperature of the hot air for heating is limited to about 350 ° C. or less at the metal part, the temperature of the exhaust heat from the hot stove is lowered, and BFG preheating cannot be performed sufficiently. .
For this reason, COG, LDG, etc. cannot be supplemented as a combustion gas of a hot stove, and the cost for that cannot be suppressed.

Further, the conventional hardware has the following problems.
In the conventional metal receiver, a part of the checker brick through-holes are blocked by the horizontal beams, causing a loss in hot air flow efficiency. That is, a large number of checker bricks are stacked in the hot air furnace, but each through hole is communicated from the upper end checker brick to the lower end checker brick, thereby circulating hot air. However, in the checker brick at the portion corresponding to the installation area of the horizontal beam in the planar shape, the through hole is blocked by the horizontal beam arranged through the receiving plate. Only the checker brick at the lowermost end is blocked by the horizontal beam, but the lower end is blocked, so that a series of through holes reaching the upper end are all unusable.

In addition, in the conventional receiving metal, a large bending load is applied to the horizontal beam. In particular, horizontal beams are subjected to continuous bending load at a temperature of about 350 ° C., so the cross-sectional dimensions have to be increased in order to obtain sufficient strength, and the aforementioned checker brick through-hole loss is reduced. It will be further encouraged.
As described above, in the conventional hot stove, there are restrictions on the temperature condition caused by the received metal parts, and it has been strongly demanded to eliminate this.

  The objective of this invention is providing the support structure of the checker brick of a hot stove furnace which can eliminate the restriction | limiting of temperature conditions, and can improve the utilization efficiency of a through-hole, and the deflection | deviation block used for this.

The deflection block of the present invention is a deflection block used in a support structure for supporting a checker brick of a hot stove, and is connected to a main body formed of a heat-resistant material, a through hole of the checker brick, and a side surface of the main body And a deflection passage that opens to the surface.
In such this invention, a checker brick is installed in the upper surface of a main body, and the through-hole and deflection path of a checker brick are connected. When arranged in this way, the flow of hot air can be secured between the through hole of the checker brick and the side surface of the main body by the deflection passage.

Therefore, if the deflection block of the present invention is used for a support structure for supporting a checker brick of a hot stove, hot air from a through hole of the checker brick is sent to a duct on the side of the bottom of the hot stove or air from the duct is sent to the checker. Can be fed into brick through-holes.
Thereby, the support structure using the deflection block of the present invention can be replaced with a conventional checker brick receiving material.

  Furthermore, since the main body of the deflection block of the present invention is formed of a heat-resistant material (for example, refractory brick), the heat-resistant temperature can be increased as compared with a conventional steel-made metal receiver. Moreover, when the deflection block of the present invention is incorporated as a support structure, the main body supports the checker brick, and the weight thereof can be received as a compression load instead of a bending load. For this reason, in the support structure using the deflection block of the present invention, the strength can be sufficiently maintained even at a high temperature, and the temperature condition can be relaxed as compared with the conventional metal support using a steel beam.

And the deflection | deviation block of this invention can ensure ventilation | gas_flowing between all the checker brick through-holes by making the deflection | deviation channel | path formed in the main body communicate with the through-hole of checker bricks. Therefore, in the support structure using the deflection block of the present invention, all of the checker brick through-holes can be used effectively, and the beam blocks a part of the checker brick through-holes as in the case of a conventional receiving metal. Therefore, the utilization efficiency of the through hole can be improved.
As described above, according to the deflection block of the present invention, it is possible to eliminate the restriction on the temperature condition and improve the utilization efficiency of the through hole.

In the deflection block of the present invention, it is preferable that the main body is formed of refractory bricks.
In such this invention, since a refractory brick is used as a heat resistant material of a main body, a high heat resistant performance can be obtained reliably. In particular, refractory bricks have a proven track record as heat-resistant materials, can be easily shaped as a main body, and can reduce manufacturing costs.
In addition, as the heat resistant material of the present invention, ceramics or other inorganic materials having heat resistance may be used. Furthermore, not only a non-metallic material but also a metal material may be used as long as heat resistance (high softening temperature and high melting temperature) is obtained.

In the deflection block of the present invention, it is preferable that the deflection passage is formed in a groove shape on the upper surface of the main body.
In the present invention, a groove is formed on the upper surface of the main body, and one end thereof is opened on the side surface of the main body to form the deflection passage. With such a deflection passage, communication between the checker brick through hole and the side surface of the main body can be secured, and the deflection passage only needs to be formed in a groove shape in the main body, so that the main body is formed into a mold such as a brick. If it exists, it can also be integrally formed at the time of the molding. Moreover, even if it is not what is integrally molded at the time of shaping | molding, since it is groove shape, post-processing can be performed easily.

  The deflection passage may be a pipe line that opens on the upper surface and side surface of the main body and is formed inside the main body. Or it is good also as a structure where one part becomes a pipe line, making the deflection channel into the groove shape mentioned above. As such a pipe line, an inclined pipe line from the upper surface to the side surface of the main body or an L-type pipe line that opens to the upper surface and the side surface can be used. Such a deflection path can also ensure communication between the checker brick through hole and the side surface of the main body.

In the deflection block according to the aspect of the invention, it is preferable that the deflection passage is formed with an inclined bottom surface so as to be lowered from a portion communicating with the through hole of the checker brick toward the opening on the side surface of the main body.
In the present invention, the vertical ventilation from the checker brick through hole can be deflected laterally and guided to the side surface of the main body by the inclination of the bottom surface of the deflection passage. Further, reverse ventilation from the side surface of the main body to the through hole can be similarly induced. Accordingly, it is possible to ensure the ventilation and deflection functions as the deflection path in the deflection block.
Furthermore, the flow path area as the deflection passage is enlarged toward the opening on the side surface due to the inclination of the bottom surface, and the resistance generated when the air flows from the plurality of through holes are combined and compressed. Can be minimized.

In the deflection block of the present invention, it is preferable that the deflection passage communicates with the through hole of the checker brick at an intermediate portion, and both ends are opened on the side surface of the main body.
In the present invention, the deflection passage can communicate with the through hole of the checker brick on the upper surface side of the main body, and can communicate with the space facing both side surfaces of the main body at the openings on both sides of the main body. Therefore, hot air from the checker brick through-hole can be received on the upper surface side of the main body, and can be distributed and guided to both sides of the main body through the deflection passage. Further, the air supplied to both sides of the main body can be merged in the deflection passage and guided to the through hole of the checker brick through the upper surface of the main body.

In the deflection block of the present invention, it is preferable that a plurality of the deflection passages are arranged in parallel, and the adjacent deflection passages are opened on the opposite side of the main body.
In the present invention, the deflection passage communicates with the checker brick through hole on the upper surface side of the main body, and adjacent deflection passages alternately open to the opposite side of the main body. Accordingly, a part of the through hole of the checker brick communicates with one side of the main body, and the other part communicates with the opposite side of the main body. Even with such a configuration, it is possible to receive hot air from the checker brick through-hole on the upper surface side of the main body and distribute and guide it to both sides of the main body through the deflection passage. Further, the air supplied to both sides of the main body can be merged in the deflection passage and guided to the through hole of the checker brick through the upper surface of the main body. Such a deflection block has a configuration in which the deflection passage formed on the upper surface side of the main body is opened only on either side, and any shape that flows in one direction (single-flow shape) may be used. Is easy.

In the deflection block of the present invention, it is preferable that a plurality of the deflection passages are arranged in parallel, and all the deflection passages are opened on one side surface of the main body.
In the present invention, the deflection passage communicates with the through hole of the checker brick on the upper surface side of the main body, and all the deflection passages are opened only on one side of the main body. Accordingly, all the checker brick through-holes facing the upper surface of the same deflection block are communicated with the space facing one side surface of the main body of the deflection block.
Such a deflection block is easy to manufacture because all the deflection passages formed on the upper surface side of the main body are aligned in the same shape (one-flow shape in the same direction). In addition, if the directions of adjacent deflection blocks are alternately reversed, the checker brick through-holes can be alternately distributed to both sides.

In the deflection block of the present invention, it is preferable that the main body has a notch formed at a facing angle position of a hexagonal columnar brick material, and a horizontal passage is formed by the notch portion.
In such this invention, the basic shape of a main body can be set according to the hexagonal column-shaped outline used as a checker brick, and the main body which has a horizontal channel | path can be formed by notching a part. Therefore, the basic shape of the deflection block can be made the same as that of the checker brick, and can be stacked in combination with each other. For example, since the deflection blocks and the checker bricks have the same hexagonal columnar shape, they can be mixed and lapped.
Note that the deflection block and the checker brick are not limited to being stacked on each other, and other stacking methods such as chimney stacking may be used.

In the deflection block of the present invention, it is preferable that the notch is formed continuously from the upper surface to the lower surface of the main body.
In the present invention, when the portion that becomes the horizontal passage is cut out from the hexagonal columnar basic shape described above, the shape can be simplified by making a continuous cut from the upper surface to the lower surface of the main body, Manufacturing can be facilitated.

In the deflection block of the present invention, it is preferable that the notch is formed only in a part between the upper surface and the lower surface of the main body.
In the present invention, when the portion that becomes the horizontal passage is cut out from the hexagonal columnar basic shape described above, the cutout is minimized by cutting out only a part between the upper surface and the lower surface of the main body. In addition to being suitable for using the heat storage function of the deflection block itself, it can also be used so as to partition the upper and lower horizontal passages at the portions left uncut.

  The support structure of the present invention is a support structure for supporting a checker brick of a hot stove, and is a support for supporting the deflection block formed of a heat-resistant material and the deflection block of the present invention that supports the checker brick. The deflection block is arranged along a virtual deflection surface that divides the interior of the hot stove up and down, and extends horizontally between the deflection block and the support member, and the side surface of the deflection block. A horizontal passage in which the openings are communicated is formed.

In the present invention, the deflection block is supported by the support member at the bottom of the hot stove, and the checker brick is supported on the upper surface of the deflection block.
At this time, in the deflection block, the through hole of the checker brick communicates with the opening on the side surface by the deflection passage. A horizontal passage is formed in the side surface of the deflection block, and this horizontal passage can be led to the side surface of the bottom of the hot stove through the deflection block and the support member. Thereby, the through hole of the checker brick is communicated with the space along the side surface of the bottom of the hot stove through the horizontal passage from the deflection passage of the deflection block.

Thus, in the support structure of this invention, both the support function of a checker brick and the ventilation function of a through-hole are ensured, and the structure replaced with the conventional receiving member can be obtained. And by using the deflection | deviation block of this invention mentioned above, heat resistance performance higher than the receiving member made from the conventional steel materials is obtained, and the loss of the through-hole by a support beam can also be eliminated.
As described above, according to the support structure of the present invention, it is possible to eliminate the restriction of the temperature condition and improve the utilization efficiency of the through hole.

In the support structure of the present invention, it is preferable that the support member is a support block having the same outer dimensions as the deflection block.
In the present invention, the support block as the support member has the same outer dimensions as the deflection block, so that they can be stacked in combination with each other. In particular, if the basic shape of the deflection block is the same hexagonal column shape as the checker brick, the basic shape of the support block is also the same hexagonal column shape, so that these support members, deflection block and checker brick can be mixed and lapped. You can also.
Note that the support member, the deflection block, and the checker brick are not limited to lap stacking, and other stacking methods such as chimney stacking may be used. These stacking methods are desirably selected as appropriate in consideration of the shape of the deflection surface on which the deflection blocks are arranged and the arrangement of the horizontal passages.

In the support structure of the present invention, the deflection block is preferably a deflection brick formed of refractory bricks, and the support block is preferably a support brick formed of refractory bricks.
In such this invention, since a deflection | deviation block and a support block are each formed with a refractory brick, high heat-resistant performance can be acquired reliably. In particular, refractory bricks have a proven track record as heat-resistant materials, can be easily shaped as a main body, and can reduce manufacturing costs.
In addition, as a support block of this invention, you may use the ceramics other inorganic material which has heat resistance. Furthermore, not only non-metallic materials but also metal materials such as cast iron may be used as long as heat resistance (high softening temperature and high melting temperature) is obtained.

In the support structure of the present invention, it is preferable that the support member is a support column that is formed of refractory bricks and supports the deflection block.
In the present invention, the number of members arranged in the height direction can be reduced by using the support columns as the support members. In addition, a horizontal passage can be formed using a space between adjacent columns. Furthermore, the space between adjacent struts can be grouped together to form a huge merge space where all the deflection passages of the plurality of deflection blocks communicate with each other and communicate with the duct on the side of the hot stove.

In the support structure of the present invention, it is preferable that the support column is formed by connecting a plurality of support column members in the longitudinal direction.
In the present invention as described above, even when a support is used as the support member, the length of each support member can be limited, which is suitable for manufacturing and transportation.

In the support structure of the present invention, it is preferable that the deflection surface is formed in a V-shape that extends obliquely upward to both sides from a reference axis that crosses the bottom surface of the hot stove.
In the present invention, by arranging the deflection block on the V-shaped deflection surface, the checker brick through hole supported on the upper surface of the deflection block communicates with the horizontal passage passing through the deflection block or the support member. Is done.
At this time, because the deflection surface is inclined, a specific region in the planar shape inside the hot stove corresponds to a specific region in the height direction of the side of the hot stove via the deflection surface. By allocating the checker brick through-holes to the horizontal passages corresponding to the respective heights, it is possible to appropriately adjust the respective flow distributions.
In addition, by making the deflection surface into a V shape composed of two inclined surfaces facing each other, the deflection blocks arranged on the deflection surface are aligned in the same direction. The horizontal passages extend on both sides of the reference axis in alignment with the reference axis. Thereby, the horizontal passages are parallel to each other, and the arrangement of the horizontal passages in the support structure is easy.

In the support structure of the present invention, it is preferable that the deflection surface is formed in a substantially conical shape or a substantially pyramid shape that extends obliquely upward from the bottom surface of the hot stove toward the outer periphery.
In the present invention, the deflection block is arranged on the deflection surface having a substantially conical shape or a substantially pyramid shape, so that the checker brick through-hole supported on the upper surface of the deflection block and the horizontal direction passing through the deflection block or the support member. The passage is in communication.
At this time, because the deflection surface is inclined, a specific region in the planar shape inside the hot stove corresponds to a specific region in the height direction of the side of the hot stove via the deflection surface. By allocating the checker brick through-holes to the horizontal passages corresponding to the respective heights, it is possible to appropriately adjust the respective flow distributions.
Moreover, by making the deflection surface substantially conical or substantially pyramidal, the deflection blocks are arranged in a circle around the central axis of the substantially conical or substantially pyramidal shape, and the horizontal passage is substantially conical or substantially pyramidal. Are formed radially about the central axis of the. Thereby, the horizontal channel | path extended to the outer peripheral side of a hot stove can be made uniform in radial direction. In particular, when the deflection block has a hexagonal columnar shape, the deflection surface is a hexagonal pyramid or triangular pyramid, and the horizontal passage is arranged in a direction intersecting the edge of the bottom surface, thereby making the horizontal passage uniform in the radial direction. The structure can be simplified.

In the support structure of the present invention, it is preferable that the deflection surface extends horizontally.
In the present invention, by arranging the deflection block on the horizontally extending deflection surface, the checker brick through-hole supported on the upper surface of the deflection block and the horizontal passage facing the side surface of the deflection block communicate with each other. Furthermore, a through space is formed on the lower surface of the horizontally extending deflection surface, and all the through holes of the checker bricks supported by the deflection block can be communicated with the merge space by communicating a horizontal passage facing each deflection block. it can. Such a merge space can be formed by the structure using the above-described support.
In such a configuration, the checker brick can be supported and the communication with the through hole can be achieved without loss, and the deflecting surface is simple and the structure can be simplified.

  According to the support structure for the checker brick of the hot stove of the present invention and the deflection block used therefor, the restriction of the temperature condition can be eliminated and the utilization efficiency of the through hole can be improved.

The heat storage chamber 3 has a cylindrical iron skin 30.
Inside the iron shell 30 of the heat storage chamber 3, a heat storage unit 31 configured by stacking a large number of checker bricks 5 is installed. The checker brick 5 will be described in detail later. The through holes formed in each checker brick 5 are stacked so as to be continuous from the upper surface to the lower surface of the heat storage unit 31, and from the bottom of the heat storage chamber 3 to the top of the furnace through the through holes. Ventilation between is possible.

  A support structure 32 according to the present invention is installed at the bottom of the iron shell 30 of the heat storage chamber 3 in order to support the heat storage unit 31.

As shown also in FIG. 2, the support structure 32 is a structure in which a support brick 6 that is a support block is stacked on the bottom surface of the heat storage chamber 3, and a deflection brick 7 that is a deflection block according to the present invention is supported thereon.
The supporting brick 6 and the deflecting brick 7 will be described in detail later. The deflecting brick 7 allows the through hole of the checker brick 5 and the ventilation space 33 to communicate with each other to allow ventilation.

In the support structure 32 of the present embodiment, the deflection bricks 7 are arranged along the virtual V-shaped deflection surfaces S1 and S2.

In the deflecting bricks 7 arranged along such deflection surfaces S1 and S2, for example, the gas Gv in the vertical direction passing through the heat storage section 31 (passing through the through hole of the checker brick 5 described above), the deflecting bricks 7 are arranged. The light is deflected by the deflected surfaces S1 and S2, and is led to the ventilation space 33 (see FIG. 2) around the support structure 32 as a gas Gh that intersects the reference axis A and in the horizontal direction.

The main body 50 has a basic shape 5P in a hexagonal column shape, and an upper surface 51 and a lower surface 52 in a regular hexagonal shape, and includes six side surfaces 53 connecting these.

The main body 50 is formed with a hexagonal cylindrical through-hole 54 that opens to the upper surface 51 and the lower surface 52, respectively.
A groove 55 having a shape obtained by dividing the through hole 54 described above into two is formed on the side surface 53. A groove 56 having a shape obtained by dividing the above-described through hole 54 into three is formed in a corner portion where the two side surfaces 53 meet.
In such grooves 55 and 56, when the checker brick 5 is stacked, the side surfaces 53 of the two main bodies 50 face each other so that the two grooves 55 form a space corresponding to one through hole 54. . Further, by gathering the corner portions of the three main bodies 50, a space corresponding to one through hole 54 is formed by the three grooves 56.

The checker brick 5 described above is lapped in the heat storage chamber 3 to form the heat storage unit 31.
As shown in FIG. 4, the checker bricks 5 are lap-stacked so that each corner portion is arranged at the center position of the checker bricks 5 stacked up and down. A space corresponding to the through hole 54 formed by the grooves 55 and 56 is communicated with the through hole 54 of the checker brick 5 stacked up and down.
Thereby, in the heat storage part 31 shown in FIG. 1 and FIG. 2, the ventilation | gas_flowing channel | path penetrated from the upper surface to a lower surface is formed over the whole surface of the horizontal direction of the heat storage part 31, and the vertical direction gas Gv shown in FIG. Distribution is maximized.
In addition, the checker brick 5 of the heat storage part 31 is good also as not a lapping but a chimney stack.

4 and 6 show the support brick 6 of the present embodiment.
In FIG. 6, the support brick 6 has a main body 60 formed by molding a firebrick brick material.
Although the basic shape 6P is a hexagonal column shape, the main body 60 has a substantially rectangular parallelepiped shape by notching a pair of diagonal corner portions. Specifically, the main body 60 has an upper surface 61 and a lower surface 62, and further includes a side surface 63 corresponding to the side surface of the basic shape 6P, and an auxiliary side surface 64 formed by cutting away a diagonal portion.
In addition, the basic shape 6P is the same shape as the basic shape 5P (see FIG. 5) of the checker brick 5, and can be overlapped and stacked together.

4 and 7 show the deflecting brick 7 of the present embodiment.
In FIG. 7, the deflecting brick 7 has a main body 70 formed by molding a refractory brick material.
Although the basic shape 7P is a hexagonal column shape, the main body 70 has a substantially rectangular parallelepiped shape by notching a pair of diagonal corners, like the supporting brick 6 (see FIG. 6). Specifically, the main body 70 has an upper surface 71 and a lower surface 72, and further includes a side surface 73 corresponding to the side surface of the basic shape 7P, and an auxiliary side surface 74 formed by cutting away a diagonal portion.
The basic shape 7P is the same shape as the basic shape 5P of the checker brick 5 (see FIG. 5) and the basic shape 6P of the support brick 6 (see FIG. 6), and can be stacked in combination with each other.

Further, a groove-shaped deflection passage 75 is formed in the deflection brick 7 from the upper surface 71 to the side surface 73 and the auxiliary side surface 74.
A plurality of the deflection passages 75 are formed in parallel with a side surface 73 where the auxiliary side surface 74 is not formed (perpendicular to the auxiliary side surface 74), each crosses the upper surface 71, and both ends are opened to the side surface 73 or the auxiliary side surface 74.
Further, a deflection passage 77 having a shape obtained by dividing the above-described deflection passage 75 into two is formed at the connection edge between the upper surface 71 and the side surface 73 where the auxiliary side surface 74 is not formed.
The deflection passage 77 forms a groove shape similar to the deflection passage 75 described above by connecting the two deflection bricks 7.

These deflection passages 75 and 77 have bottom surfaces 76 formed in a mountain shape, and are inclined so as to descend from the center toward both ends.
These deflection passages 75 and 77 are arranged so that all the through holes 54 of the upper checker brick 5 communicate with any one of the deflection passages 75 and 77 when lap-stacked together with the checker brick 5 as shown in FIG. Has been placed.

The support brick 6 and the deflecting brick 7 described above are lap-stacked on the bottom of the heat storage chamber 3 on the basis of the basic shapes 6P and 7P, thereby forming the support structure 32.
A horizontal passage 35 of the present invention extending in a direction orthogonal to the reference axis A is formed between the supporting brick 6 and the deflecting brick 7 lap-stacked as the supporting structure 32.
Such a support structure 32 is constructed as follows.

In FIG. 4, the bottom layer of the support structure 32 is installed on the bottom surface of the heat storage chamber 3. In the lowermost layer, one or two deflecting bricks 7 are arranged along the reference axis A, and the supporting bricks 6 are sequentially arranged on both sides (crossing direction with the reference axis A). The supporting brick 6 is installed so that the side surfaces 63 without the auxiliary side surfaces 64 are in close contact with each other and are continuous in a direction orthogonal to the reference axis A.
In the row of the deflecting brick 7 and the supporting brick 6 installed in this way, the auxiliary side surfaces 64 and 74 are arranged in series, and a space is formed between the auxiliary side surfaces 64 and 74 of other adjacent rows. . By this interval, a horizontal passage 35 extending in a direction orthogonal to the reference axis A is formed.

On the lowermost supporting brick 6, the checker brick 5, the deflecting brick 7 and the supporting brick 6 are installed as a second layer in order from the position of the reference axis A to the outside in the crossing direction.
The checker brick 5 of the second layer forms the heat storage part 31 as described above, and is installed on the deflection brick 7 of the lowermost layer.
The second layer of deflection bricks 7 is disposed outside the checker bricks 5 and supported on the lowermost support bricks 6.
The second-layer supporting brick 6 is disposed outside the deflecting brick 7 and is supported on the lowermost supporting brick 6.

  Further, the third layer is similarly arranged on the second layer, and the lower level deflection bricks 7 are always arranged immediately below the upper level checker bricks 5. At this time, all the through holes 54 of the upper checker brick 5 communicate with the deflection passages 75 and 77 of the lower deflection brick 7, and the lower deflection brick 7 and the supporting brick 6 are connected via the deflection passages 75 and 77. Is communicated with a horizontal passage 35 between the two.

In this way, in each level, the checker brick 5, the deflecting brick 7 and the support brick 6 are sequentially arranged outward from the position of the reference axis A, and are respectively lap-stacked on the lower level, whereby the support structure 32 and the heat storage unit 31 are arranged. The lower part of will be formed.
In such a support structure 32, the deflection bricks 7 are arranged so as to be separated from the reference axis A along the upper layer, and the deflection surfaces S1 and S2 rising in a V shape on both sides of the reference axis A (FIGS. 2 and 3). Reference).

As shown in FIG. 8, in each level of the support structure 32 having the V-shaped deflection surfaces S <b> 1 and S <b> 2, the horizontal passage 35 formed between the deflection brick 7 and the support brick 6 intersects the reference axis A. Arranged in the direction.
In the region Rv along the reference axis A, the checker brick 5 constituting the lower part of the heat storage unit 31 is installed. In this region Rv, the gas Gv in the vertical direction (see FIGS. 2 and 3) can be ventilated through the through hole 54 of the checker brick 5.

  The deflection brick 7 is installed in the region Rt outside the region Rv (the side away from the reference axis A). In this region Rt, the gas Gv from the through hole 54 of the upper checker brick 5 is guided to the horizontal passage 35 facing the auxiliary side surface 74 via the deflection passages 75 and 77, and is deflected in the horizontal direction to be gas. Gh.

  Support bricks 6 are installed in a region Rh outside the region Rt. In this region Rh, the horizontal passage 35 formed between the deflection bricks 7 in the region Rt continues to communicate with the horizontal passage 35 between the auxiliary side surfaces 64 of the support brick 6. The horizontal passage 35 between the support bricks 6 is led to the outside of the support structure 32 as it is, and communicated with the ventilation space 33 or the ventilation pipe 34 around the support structure 32.

  Therefore, in the support structure 32 of the present embodiment, the vertical gas Gv is deflected by the deflection passages 75 and 77 of the deflecting brick 7 and taken out as the horizontal gas Gh by the horizontal passage 35 (or in the opposite direction). Flow).

According to this embodiment, there are the following effects.
In the deflection brick 7 incorporated in the support structure 32, the checker brick 5 is installed on the upper surface of the main body 70, and the through-hole 54 of the checker brick 5 and the deflection passages 75 and 77 are communicated with each other, thereby passing through the deflection passages 75 and 77. The through hole 54 and the horizontal passage 35 can be communicated with each other to ensure the flow of hot air.

As a result, the vertical gas Gv from the through hole 54 of the checker brick 5 can be deflected and sent to the ventilation space 33 or the ventilation pipe 34 as the horizontal gas Gh.
In addition, air flow in the reverse direction is also possible, and the air from the ventilation pipe 34 is taken into the deflecting brick 7 from the horizontal passage 35, deflected by the deflecting passages 75 and 77, and sent to the through hole 54 of the checker brick 5. You can also.
Therefore, the support structure 32 using the deflecting brick 7 of the present embodiment can replace the conventional checker brick receiving material.

In this embodiment, the deflection brick 7 is used as a deflection block, the support brick 6 is used as a support member, and these can be incorporated to constitute the support structure 32.
Here, the deflecting brick 7 and the supporting brick 6 are formed of refractory bricks whose main bodies 70 and 60 are heat-resistant materials, so that the heat-resistant temperature can be increased as compared with the conventional steel-made metal receiver.
In particular, refractory bricks have a proven track record as heat resistant materials, can be easily shaped as the main bodies 70 and 60, and can also reduce manufacturing costs.

Further, when the deflecting brick 7 and the supporting brick 6 are incorporated as the support structure 32, the main body 70 can support the checker brick 5, and the main body 60 can support the deflecting brick 7 or another supporting brick 6. Each can be received as a compressive load rather than a bending load.
For this reason, in the support structure 32 using the deflection brick 7 and the support brick 6, it is possible to maintain sufficient strength even at high temperatures, and the temperature condition can be relaxed as compared with a conventional metal support using a steel beam. it can.

Further, in the deflecting brick 7 of the present embodiment, the deflection passages 75 and 77 formed in the main body 70 can be communicated with the through hole 54 of the checker brick 5, and air can flow between all of the through holes 54 of the checker brick 5. Can be secured.
Therefore, in the support structure 32 using the deflecting brick 7 of the present embodiment, all the through holes 54 of the checker brick 5 can be used effectively, and the beam is a through hole of the checker brick 5 like a conventional receiving metal. The utilization efficiency of the through-hole 54 can be improved without blocking part of 54.

  As described above, in the present embodiment, by using the deflection brick 7 according to the present invention and the support structure 32 incorporating the same, the restriction of the temperature condition due to the support structure of the checker brick 5 in the hot stove 1 is eliminated, and The utilization efficiency of the through hole can be improved.

In the present embodiment, a groove shape is formed on the upper surface 71 of the main body 70 of the deflection brick 7, and one end thereof is opened on the side surface 73 or the auxiliary side surface 74 of the main body 70, thereby forming the deflection passages 75 and 77.
Such deflection passages 75 and 77 can ensure communication between the through hole 54 of the checker brick 5 and the side surface 73 or the auxiliary side surface 74 of the main body 70, and the deflection passages 75 and 77 can be formed in the main body 70 in a groove shape. For this reason, if the main body 70 is formed of a mold such as brick, it can be integrally formed at the time of forming. Moreover, even if it is not what is integrally molded at the time of shaping | molding, since it is groove shape, post-processing can be performed easily.

In the present embodiment, the vertical gas Gv from the through hole 54 of the checker brick 5 is deflected by the inclination of the bottom surface 76 of the deflection passages 75 and 77, and the side surface 73 or the auxiliary side surface of the main body 70 is obtained as the horizontal gas Gh. It is possible to guide to the horizontal passage 35 facing 74. Further, airflow in the reverse direction from the horizontal passage 35 to the through hole 54 via the deflection passages 75 and 77 can be similarly induced. Accordingly, it is possible to ensure the ventilation and deflection functions as the deflection path in the deflection block.
Further, due to the inclination of the bottom surface 76, the flow passage area as the deflection passages 75 and 77 increases toward the opening of the side surface 73 or the auxiliary side surface 74, and when the ventilation from the plurality of through holes 54 is merged. However, it is possible to minimize the resistance that occurs when this is compressed.

  Note that the deflection passages 75 and 77 of the present embodiment are opened on the side surfaces 73 or the auxiliary side surfaces 74 on both sides of the main body 70 and have a bottom surface 76 having a high mountain-shaped slope at the center. The vertical gas Gv from the through-hole 54 of the checker brick 5 can be received on the 71 side, distributed to the horizontal passages 35 on both sides of the main body 70 through the deflection passages 75 and 77, and guided as the horizontal gas Gh. Conversely, the air supplied to the horizontal passages 35 on both sides of the main body 70 can be merged in the deflection passages 75 and 77 and guided to the through hole 54 of the checker brick 5 via the upper surface 71 of the main body 70. .

In the present embodiment, the basic shapes 5P, 6P, and 7P of the checker brick 5, the support brick 6, and the deflecting brick 7 are formed in a common hexagonal shape, and therefore, lap stacking can be performed in combination with each other.
Further, in the supporting brick 6 and the deflecting brick 7, the auxiliary side surfaces 64 and 74 are formed by notching the opposing angular positions of the hexagonal columnar main bodies 60 and 70, so that the auxiliary side surfaces 64 and 74 are used while using the common basic shapes 6P and 7P. The horizontal passage 35 can be formed by 74.

  In the present embodiment, when the horizontal passage 35 is formed on the side surfaces of the support brick 6 and the deflection brick 7, the opposing angular positions of the hexagonal columnar main bodies 60, 70 are continuously provided from the upper surface 61, 71 to the lower surface 62, 72. Notches were formed, thereby forming auxiliary side surfaces 64 and 74. By making such a continuous notch from the upper surface 61, 71 to the lower surface 62, 72, the shape can be simplified and the manufacturing can be facilitated.

  In the present embodiment, in the support structure 32, V-shaped deflection surfaces S <b> 1 and S <b> 2 are formed that extend obliquely upward from the reference axis A crossing the bottom surface of the heat storage chamber 3 to both sides. Then, by arranging the deflecting bricks 7 on the V-shaped deflecting surfaces S1 and S2, the through holes 54 of the checker bricks 5 supported on the upper surface of the deflecting bricks 7 and the deflecting bricks 7 or supporting bricks 6 are provided. The horizontal passage 35 that passes through can be communicated by the deflection passages 75 and 77.

  At this time, since the deflection surfaces S1 and S2 are inclined, a specific region (region Rt in which the deflection brick 7 is installed) in the planar shape inside the heat storage chamber 3 is stored as heat through the deflection surfaces S1 and S2. It corresponds to a specific area in the height direction of the ventilation space 33 around the furnace bottom of the chamber 3, and the through holes 54 of the checker bricks 5 facing the areas Rt in each level of the support structure 32 are set to each height. By allocating to the corresponding horizontal passage 35, each flow distribution can be adjusted appropriately.

  Moreover, the deflection bricks 7 arranged on the deflection surfaces S1 and S2 are aligned in the same direction by making the deflection surfaces S1 and S2 into a V shape formed by two inclined surfaces facing each other. The horizontal passages 35 extend on both sides of the reference axis A in the direction intersecting with the reference axis A. Accordingly, the horizontal passages 35 are parallel to each other, and the arrangement design of the horizontal passages 35 in the support structure 32 can be facilitated.

[Second Embodiment]
9 and 10 show a second embodiment of the present invention.
In the first embodiment described above, the V-shaped deflection surfaces S1 and S2 are set. However, the present embodiment uses a substantially conical deflection surface S3.
In addition, this embodiment differs in shape of deflection surface S3 from 1st Embodiment mentioned above, and the arrangement | sequence of the deflection brick 7, the support brick 6, and the checker brick 5 in the support structure 32 differs in connection with this. However, in the present embodiment, the structure of the hot stove 1, the structure of the heat storage unit 31 and the support structure 32, the structure of the deflecting brick 7, the support brick 6 and the checker brick 5 are the same as those in the first embodiment described above.
Therefore, in the following description, only different parts from the first embodiment will be described.

As shown in FIG. 9, the deflection surface S <b> 3 of the present embodiment is an inverted conical virtual surface whose apex is the center of the bottom surface of the iron skin 30 of the heat storage chamber 3.

In the support structure 32 of the present embodiment, the horizontal passages 35 are arranged radially from the center of the deflection surface S3. By this horizontal passage 35, the gas Gh in the horizontal direction from the deflecting brick 7 is sent out radially from the center of the deflecting surface S3.

In the present embodiment, as the substantially conical deflecting surface S3, for example, when the basic shapes 7P, 6P, 5P having the same hexagonal column shape are used as the deflecting brick 7, the supporting brick 6, and the checker brick 5, these basic shapes are used. It is desirable to use a hexagonal pyramid or triangular pyramid-shaped deflecting surface S3 corresponding to the corresponding hexagon.
As shown in FIG. 10, at an arbitrary level of the support structure 32, the checker brick 5 constituting the lower part of the heat storage unit 31 is arranged at the center, the deflecting brick 7 is arranged around the checker brick 5, and the support brick is arranged therearound. It can be set as the structure by which 6 is arrange | positioned.

In such a configuration, it is desirable that the deflection surface S3 on which the deflection brick 7 is arranged is a hexagonal column. Moreover, as the horizontal channel | path 35, it is desirable to set it as the horizontal channel | path 35 which faces the cross direction outward from each hexagonal side where the deflection | deviation brick 7 is arrange | positioned.
Also according to this embodiment, the same effect as that of the first embodiment described above can be obtained.

[Third Embodiment]

On the other hand, in this embodiment, the support bricks 6A and 6B and the deflecting brick 7A are used in order to simplify and share the members constituting the support structure 32A.

  In FIG. 12, the supporting brick 6A has a main body 60A formed by molding a refractory brick, the upper surface 61A and the lower surface 62A of the main body 60A are rectangular, and a pair of side surfaces 63A are trapezoids that narrow downward. The other pair of side surfaces 64A are inclined rectangles.

Here, the width of the short side of the upper surface 61A is set to be equal to or longer than the length of one side of the hexagon in the basic shape 5P of the checker brick 5 described above in consideration of the overlap margin. The height of the main body 60A is equal to the height of the checker brick 5 described above.
Therefore, the supporting brick 6A can be stacked in combination with the checker brick 5 described above.

  In FIG. 13, the support brick 6B has a main body 60B or a side surface 64B similar to the support brick 6A described above. However, the main body 60B to the side surface 64B are upside down with respect to the main body 60A to the side surface 64A of the support brick 6A described above. For this reason, it can be set as the support brick 6B by using the support brick 6A upside down.

In FIG. 14, the deflecting brick 7A has a main body 70A or a side surface 74A. The main body 70A to the side surface 74A are the same as the main body 60A to the side surface 64A of the support brick 6A described above.
Further, in the deflecting brick 7A, groove-shaped deflecting passages 75A and 77A are formed on the upper surface 71A, and both ends of the deflecting brick 7A are opened on the side surface 74A. These deflection passages 75A and 77A are the same as the deflection passages 75 and 77 of the first embodiment described above, and the bottom surface 76A has a mountain shape inclined on both sides.

As shown in FIG. 11, the support bricks 6A and 6B and the deflecting bricks 7A described above are sequentially stacked on the bottom of the heat storage chamber 3 (see FIG. 2), thereby forming a support structure 32A.
Also in this embodiment, similarly to the first embodiment described above, the deflecting brick 7A is arranged along the virtual V-shaped deflection surfaces S1 and S2 (see FIG. 3).

Here, in the first embodiment described above, the support brick 6, the deflecting brick 7 and the checker brick 5 are lap-stacked to form the support structure 32, and the heat storage unit 31 above the lap stack is also the checker brick 5.
On the other hand, in the present embodiment, the heat storage units 31 above the level where all the checker bricks 5 become the checker bricks 5 are lap stacks, but the support structure 32A and the checker bricks 5 (lower portions of the heat storage units 31) in the same level are stacked in the chimney. It is a hybrid stack structure that combines lap stack and chimney stack.
In addition, the heat storage part 31 more than the hierarchy from which all become the checker bricks 5 is good also as not a lapping but a chimney stack.

In FIG. 11, support bricks 6B are arranged on the bottom surface of the heat storage chamber 3 as the lowermost layer of the support structure 32A. The arrangement direction of the support bricks 6B is a direction intersecting with the reference axis A. A predetermined distance is secured between the support bricks 6B of each row.
As the second layer, in the region near the reference axis A, the deflection brick 7A is installed on the support brick 6B, and on the outside, the support brick 6A is installed on the support brick 6B.

As the third layer, the checker brick 5 is installed on the deflecting brick 7A, and the support brick 6B is installed on the support brick 6A.
As the fourth layer, the checker bricks 5 are installed concentrically on the checker bricks 5 (chimney stacking). Further, in a region adjacent to the checker brick 5, the deflection brick 7A is installed on the support brick 6B, and the support brick 6A is installed on the support brick 6B outside thereof.

  Hereinafter, by repeating these steps, the area of the checker brick 5 near the reference axis A expands to the outside, and when all the layers become the checker brick 5, the checker brick 5 is switched to the lap stack, and the heat storage unit 31 is It is formed.

  In the support structure 32A constructed as described above, the space sandwiched between the inclined side surfaces 64A in the portion where the support bricks 6A and 6B are stacked and the portion where the deflection brick 7A is stacked on the support brick 6B. This space is formed with a horizontal passage 35A that intersects the reference axis A along the row of the supporting bricks 6A and 6B and goes outward.

  In the heat storage part 31, the through-holes 54 of the checker brick 5 are communicated with each other regardless of whether it is a lap stacking part or a chimney stacking part. The through hole 54 of the lowermost checker brick 5 communicates with the deflection passages 75A and 77A of the deflection brick 7A, and further communicates with the horizontal passage 35A from the opening of the side surface 74A.

Therefore, in the present embodiment, as in the first embodiment described above, the vertical gas Gv (see FIG. 3) from the heat storage unit 31 is deflected by the deflecting brick 7A and the horizontal gas Gh (FIG. 3). As a reference) to the horizontal passage 35A.
As described above, the support structure 32A of the present embodiment can provide the same effects as those of the first embodiment described above.

Furthermore, in this embodiment, the supporting bricks 6A and 6B and the deflecting brick 7A are used as members of the supporting structure 32A, and each has a simple shape.
Further, the supporting brick 6B can be shared for supporting the supporting brick 6A and supporting the deflecting brick 7A, and the supporting brick 6B is obtained by inverting the supporting brick 6A, and substantially 2 of the supporting brick 6A and the deflecting brick 7A. What is necessary is just to prepare a kind, a construction can be simplified and manufacturing cost can be reduced.

[Fourth Embodiment]
15 to 19 show a fourth embodiment of the present invention.
In the first and third embodiments described above, the V-shaped deflection surfaces S1 and S2 are used, and in the second embodiment, a substantially conical (pyramidal) deflection surface S3 is used. On the other hand, in the present embodiment, a horizontal deflection surface S4 is used.
In the first to third embodiments described above, the supporting bricks 6, 6A and 6B are used as the supporting members, respectively. On the other hand, in this embodiment, the support | pillar 8 is used as a support member.

In FIG. 15, a support structure 32 </ b> C is installed at the bottom of the iron skin 30 of the heat storage chamber 3, and the heat storage unit 31 formed of the checker brick 5 is supported by the support structure 32 </ b> C.
As shown also in FIG. 16, the support structure 32C has the support | pillar 8 installed in the bottom face of the thermal storage chamber 3, and the deflection brick 7C supported by the upper end, and the deflection brick 7C is on the horizontal deflection surface S4. Are arranged along.
A gap is formed between the columns 8, and a large merge space 33C is formed on the lower surface side of the deflection surface S4 due to the gap between these columns 8 and the cylindrical space between the support structure 32C and the iron shell 30. Has been.
A ventilation pipe 34 communicating with the merge space 33 </ b> C is connected to the side surface of the iron skin 30.

The column 8 is configured by connecting a plurality of cylindrical column members 80.
As shown in FIG. 17, the column member 80 has a cylindrical peripheral surface 83 with an upper surface 81 and a lower surface 82 that are circular. The support member 80 is made of a ceramic material having high heat resistance.

As shown in FIG. 18, the deflecting brick 7C has a main body 70C having an inverted truncated cone shape.
The main body 70C has a circular upper surface 71C and a lower surface 72C, and has a side surface 74C that is a conical surface. The lower surface 72 </ b> C has the same shape as the upper surface 81 of the column member 80 described above, and can be connected to the upper end of the column 8.
In the deflection brick 7C, groove-shaped deflection passages 75C and 77C are formed on the upper surface 71C, and both ends of the deflection brick 7C are opened on the side surface 74C. These deflection passages 75C and 77C are the same as the deflection passages 75 and 77 of the first embodiment described above, and the bottom surface 76A has a mountain shape inclined on both sides.

Returning to FIG. 16, such a deflecting brick 7 </ b> C is supported by the support column 8 to form a support structure 32 </ b> C. When the checker brick 5 is installed on the upper surface of the deflection brick 7C, the through hole 54 communicates with the deflection passages 75C and 77C and communicates from the opening of the side surface 74C to the merge space 33C.
Therefore, even with the support structure 32C of the present embodiment, the ventilation space 34C or the ventilation pipe 34 is ventilated via the communication from the through hole 54 of the checker brick 5 of the heat storage unit 31 to the deflection passages 75C and 77C. It can be carried out.

In this embodiment, the checker brick 5 is the same as that of the first embodiment described above (see FIG. 5), but the lowest layer stacked as the heat storage unit 31, that is, the one directly received by the deflection brick 7C. Only the flow rate adjustment checker brick 5C shown in FIG. 19 is used.
The flow rate adjustment checker brick 5C is basically configured in the same manner as the checker brick 5 described with reference to FIG. However, the through holes 54 are of a plurality of types having different cross-sectional areas.

In FIG. 19, the through hole 54 </ b> A has the same dimensions as the checker brick 5 described in FIG. 5. The through hole 54B has a smaller cross-sectional area than the through hole 54A. The through hole 54C has a smaller cross-sectional area than the through hole 54B.
By using such a flow rate adjustment checker brick 5C, the flow can be reduced at the lower end portion even if the through holes 54 of the checker brick 5 stacked above have the same size.

For example, when the flow resistances in the deflection passages 75C and 77C following the through hole 54 are different from each other, the flow rate of the through hole 54 having a small flow resistance (from the lower end to the upper end of the heat storage unit 31) is large, and the through hole 54 having a large flow resistance. Then, the imbalance that the flow rate becomes small occurs.
On the other hand, if the flow rate adjustment checker brick 5C is used and the through holes 54A to 54C are selectively used according to the flow resistance of the deflecting brick 7C or the like, the flow rate balance of each through hole 54 can be achieved.

[Fifth Embodiment]
20 to 21 show a fifth embodiment of the present invention.
This embodiment has the same configuration as that of the fourth embodiment described above except for a part. Accordingly, the same components are denoted by the same reference numerals, and redundant description is omitted, and differences will be described below.

In the fourth embodiment described above, the support column 8 is configured by connecting the cylindrical support member 80.
Also in this embodiment, the column 8 is formed by connecting cylindrical column members 80, but spacer members 84 are interposed between the column members 80 as shown in FIG. 21.
In FIG. 22, the spacer member 84 has a prismatic protrusion 86 formed around a base 85 having the same diameter as the column member 80.
The protrusions 86 are formed in six directions from the base 85 corresponding to the hexagonal columnar checker brick 5 used in the present embodiment.

In FIG. 20, when the spacer member 84 is sandwiched between the support members 80, the base 85 continues to the support members 80 and the protrusions 86 protrude in 6 directions.
When the column 8 formed by connecting the spacer member 84 and the column member 80 is installed on the bottom surface of the heat storage chamber 3, the projection 86 of the spacer member 84 is replaced with the projection 86 of the adjacent column 8. It is matched.

With such a configuration, the support column 8 can be supported through the protruding portions 86 that are abutted with each other even if any of the columns 8 falls. Therefore, the strength of the support column 8 can be increased and the strength of the support structure 32C can be increased.
Further, the protrusion 86 protrudes into the merge space 33C, so that a turbulent flow can be generated in the gas passing through the merge space 33C.

[Modification]
It should be noted that the present invention is not limited to the above-described embodiments, and modifications and the like within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the deflection brick 7 and the support brick 6 in the first embodiment, in order to form the horizontal passage 35, the opposing corners 74 of the hexagonal columnar basic shapes 7P, 6P are cut out from the upper end to the lower end, Although 64 is formed, the part cut out to form the horizontal passage 35 may be only a part in the height direction.

In each of the embodiments described above, the deflection passages 75 and 77 have a groove shape whose upper side is opened over the entire length, but part or all of the upper surface may be covered.
In FIG. 27, the deflecting brick 7 has the same configuration as that of the first embodiment described above, but the deflecting passages 75 and 77 have a margin where the upper surface 71 and the side surface 73 or the auxiliary side surface 74 merge. In the portion, deflection passages 75 and 77 are formed in a tubular shape.

The structure of FIG. 27 can be formed by drilling from both directions along the bottom surface 76, for example, because the deflection passages 75 and 77 are straight.
On the other hand, L-shaped deflection passages 75 and 77 can also be formed by performing drilling in the lateral direction from the side surface 73 or the auxiliary side surface 74 and performing drilling in the upper surface 71 so as to communicate with the hole. .

Thus, the deflection passages 75 and 77 are not limited to the groove opening structure, but may be a tunnel shape, a straight tube shape, or an L-shaped tunnel.
Further, in each of the above embodiments, the bifurcated deflecting passage 77 that becomes the deflecting passage 75 is formed by joining with the adjacent deflecting brick 7. However, depending on the arrangement of the through holes 54 of the checker brick 5, only the deflecting passage 75 is used. There may be.

  In the first to third embodiments, the deflecting bricks 7 and 7A and the supporting bricks 6 have the basic shapes 7P and 6P each having a hexagonal column shape similar to that of the checker bricks 5. However, the present invention is not limited to this. Other shapes may be used.
