DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain storage portion forming panel for forming a side wall of a storage space for storing grain for drying or storage.

[0002]

2. Description of the Related Art Conventionally, such a panel for forming a grain storage section has conventionally been constituted by a single flat plate (hereinafter sometimes referred to as a veneer).

[0003]

By the way, the panel is
In order to withstand the pressure applied in the panel thickness direction when the grain is stored, it is necessary to make the strength in the panel thickness direction equal to or higher than a predetermined strength. Conventionally, in order to ensure strength in the panel thickness direction, it is necessary to increase the thickness of the veneer, and there has been a problem that the weight of the panel increases. When the weight of the panel is increased, for example, a problem such as an increase in the burden on an operator during construction occurs. Also, as the weight of the panel increases, the strength of the pillars and beams supporting the panel must be increased, so that the material cost for forming the grain storage unit increases, and the production cost of the grain storage unit increases. Problem arises.

[0004] In order to solve such a problem, there is a panel in which a panel is formed of a corrugated sheet in which a sheet material is formed into a corrugated (sine or rectangular) shape. When the panel is made of a corrugated sheet, the thickness of the plate material for forming the corrugated sheet is greater than the thickness of the veneer when the panel is made of a veneer in a state where the strength in the panel thickness direction is secured. Since the panel can be made thin, the weight of the panel can be reduced as compared with the case where the panel is made of a single plate. However, when the panel is formed of a corrugated plate, an operation for assembling the corrugated plate to a pillar or a beam to form a storage space becomes complicated. Further, since the surface of the panel on the storage space side is an uneven surface, there is a problem that the concave portion becomes a dead space in the storage space. When a dead space occurs in the storage space, for example, when storing grains in the storage space for drying, various air such as drying air does not spread to the grains in the dead space, and the grains in the dead space are not stirred. Problems arise.

The present invention has been made in view of the above circumstances, and has as its object to reduce the cost and weight and to form a grain storage portion capable of forming a storage space without producing a dead space. To provide a panel.

[0006]

According to the characteristic feature of the present invention, the panel is located at a distance in the panel thickness direction and has a pair of rectangular shapes forming a pair of panel surface portions. It is configured to include a plate-shaped portion and a reinforcing portion that is located in an internal space between the pair of plate-shaped portions and connects the pair of plate-shaped portions, in order to reinforce strength in a panel thickness direction. So that the pressure applied from the inside of the storage space in the thickness direction of the panel is supported not only by the plate-like portion on the inside, but also by the reinforcing portion and the plate-like portion on the outside of the storage space. Become. Therefore, while ensuring strength in the thickness direction of the panel, the combined thickness of the plate-shaped portions can be made smaller than the thickness of the veneer when the panel is composed of veneer. Can be made lighter than before. Then, by using such a panel, the burden on the worker at the time of construction can be reduced. Further, since the weight of the panel can be reduced, the strength of the columns and beams supporting the panel can be reduced, so that the material cost for forming the grain storage unit is reduced, and the production cost of the grain storage unit is reduced. be able to.

[0007] Further, as the panel, a pair of rectangular plate-like portions forming a pair of panel surface portions and a pair of plate-like portions located in an internal space between the pair of plate-like portions are connected. Despite having a reinforcing section, the outer shape of the entire panel can be a rectangular flat plate, so that it is assembled to columns and beams to form a storage space, compared to the conventional configuration made of corrugated plates. Work becomes easier. In addition, the panel
By assembling the flat surface of the panel so as to face the storage space, the storage space can be formed without generating a dead space.

According to the characteristic structure of the second aspect, the reinforcing portion is formed so as to include a vertical reinforcing portion and a horizontal reinforcing portion along the vertical and horizontal width directions of the panel when viewed in the panel thickness direction. Therefore, the vertical reinforcing portion and the horizontal reinforcing portion can resist bending of the panel in both the vertical direction and the horizontal direction. Therefore, since the reinforcement of the strength in the panel thickness direction by the reinforcing portion can be further strengthened, the thickness of each plate-shaped portion can be further reduced while securing the strength in the panel thickness direction, The weight reduction of the panel can be further promoted.

According to a third aspect of the present invention, there is provided a plate portion for forming a portion of a pair of plate portions and a reinforcing portion for forming a portion of the reinforcing portion. So that the cross-sectional shape becomes rectangular so as to have a plate part,
Form a square tubular body. Then, a plurality of the square tubular bodies are
A plate portion for forming a pair of plate-like portions in a plurality of rectangular tube-like members arranged side by side in a panel width direction in a state where plate portions for forming reinforcement portions of adjacent rectangular tube-shaped members are connected to each other. , A pair of plate-like portions, and a reinforcing portion is formed by a plate portion for forming a reinforcing portion. That is, a panel is manufactured by a simple method of simply arranging a plurality of square tubular bodies in a panel width direction in close contact with each other and connecting adjacent walls of the adjacent square tubular bodies in the panel width direction. Can be. By the way, a pair of rectangular plate members for forming a pair of plate-shaped portions are arranged at intervals, and a reinforcing portion forming material for forming a reinforcing portion is located between the pair of plate materials, A method of manufacturing a panel by connecting the reinforcing portion forming material and each of the two plate materials can be considered. However, in this method, the work for connecting the reinforcing portion forming material and the plate material between the pair of plate-shaped portions is complicated and difficult. Therefore, according to the characteristic configuration of claim 3, the processing cost of the panel is reduced,
Panel prices can be reduced.

According to a fourth aspect of the present invention, a reinforcing member for connecting a pair of plate-shaped portions to each other is provided inside the rectangular tubular body, and a plurality of juxtaposed parallel members are provided. The reinforcing portion is formed by the plate portion for forming the reinforcing portion and the reinforcing material inside the rectangular cylindrical body in the rectangular cylindrical body. Therefore, since the reinforcement of the strength in the panel thickness direction by the reinforcing portion can be further strengthened, the thickness of each plate-shaped portion can be further reduced while securing the strength in the panel thickness direction, The weight reduction of the panel can be further promoted.

According to the fifth aspect of the present invention, since the frame material is provided on the end surface of the entire peripheral portion of the panel, the panel can be assembled to a pillar or a beam using the frame material. In other words, when attaching panels to pillars or beams using the edges of a pair of plate-like parts,
Since there is an interval between the pair of plate-shaped portions, it is necessary to secure a predetermined mounting strength while maintaining the interval, and to assemble the plate, which makes the operation complicated and difficult. On the other hand, if you try to assemble using frame material,
Can be easily assembled. Therefore, the use of the panel having the characteristic configuration according to claim 5 simplifies the work of assembling the panel, thereby reducing the production cost of the grain storage unit.

[0012] According to the characteristic structure of the sixth aspect, the frame material is formed to have a width in the panel thickness direction smaller than the thickness of the panel, so that the end surface of the entire peripheral portion of the panel in the panel thickness direction. It is provided biased to one end. Therefore, in order to assemble the panel to the pillar or beam, the pillar or beam side is provided with a mounting frame having a shape substantially the same as the shape of the frame material when viewed in the panel thickness direction. Then, the panel is arranged such that the mounting frame on the pillar or beam side is fitted to a frame material-free portion on the end face of the entire periphery of the panel and hits the frame material, and the frame material and the mounting frame are connected. By doing so, it is possible to prevent the panel from protruding into the storage space.
Therefore, by using the panel having the characteristic configuration according to claim 6, the thickness of the side wall portion of the storage space in the grain storage unit can be reduced, so that the grain storage unit can be made compact while securing a desired storage volume. Can be

[0013] According to the characteristic configuration of the present invention, the reinforcing portion is configured to reinforce the same strength in the entire panel width direction. By making the panel different, a plurality of types of panels having different strengths in the panel thickness direction can be manufactured. By the way, in the state where the grain is stored in the storage space, the pressure applied to the side wall of the storage space becomes stronger toward the lower side. Therefore, when a plurality of panels are arranged side by side in the vertical direction to form a side wall portion, a plurality of types of panels having different strengths in the panel thickness direction are positioned, and a panel having a higher strength in the panel thickness direction is positioned downward. In this state, by arranging in the vertical direction, the strength required for the entire side wall portion is ensured.

By the way, in order to reduce the reinforcing strength of the reinforcing portion, that is, to decrease the strength in the panel thickness direction,
For example, the thickness of the reinforcing portion in the panel width direction may be reduced, or the interval between adjacent reinforcing portions in the panel width direction may be increased. Further, even if the thickness of the plate portion is reduced, the strength in the panel thickness direction can be reduced. By reducing the strength in the panel thickness direction in this manner, the material cost of the panel is reduced, so that the cost of the panel can be reduced and the weight of the panel can be reduced. Therefore, by using a plurality of types of panels having different strengths in the panel thickness direction obtained by the characteristic configuration according to claim 7, the strength required for the entire grain storage unit is sufficiently ensured, and Since the material cost occupied can be reduced and the total weight of the panel can be reduced, the production cost of the grain storage unit can be further reduced.

According to the characteristic configuration of the eighth aspect, the reinforcing portion is configured to reinforce the strength in a state where the strength is sequentially changed from one end side to the other end side in the panel width direction. By the way, in the state where the grain is stored in the storage space, the pressure applied to the side wall of the storage space becomes stronger toward the lower side.
Therefore, the strength required for the entire side wall portion is secured by arranging the panels whose strength sequentially changes from one end side to the other end side in the panel width direction in such a manner that the strength becomes stronger toward the lower side. To do. By the way, from the one end side in the panel width direction toward the other end side, the thickness in the panel width direction of the reinforcing portion is gradually reduced, or by sequentially increasing the interval between the reinforcing portions adjacent in the panel width direction, The reinforcement strength can be changed so as to decrease sequentially from one end side to the other end side in the panel width direction, but by doing so, the material cost of the panel decreases,
The cost of the panel can be reduced, and the weight of the panel can be reduced. Therefore, by using the panel obtained by the characteristic configuration according to claim 8, while reducing the material cost occupied by the panel while sufficiently securing the strength required as the whole grain storage unit,
Since the total weight of the panel can be reduced, the production cost of the grain storage can be further reduced.

Next, with reference to FIGS. 6 to 12, a description will be given of a grain drying and storage facility in which the side walls of a storage space for storing grains are formed using the panel P configured as described above. As shown in FIG. 6 to FIG. 8, the grain storage and drying facility arranges five silos S having storage storage spaces for storing and storing grains in a straight line along a predetermined direction, and also drying the grains. Five storage bins D each having a storage space for drying to be processed are provided on the left and right sides, and a total of 10 storage bins D are arranged side by side along the predetermined direction in a state where the storage bins D are arranged adjacent to the left and right sides with respect to the silo S.

Similarly, in the studs 7, a plate-like material 9 is attached by welding to parts other than both ends which are parts to be attached to the beam 6 so as to cover the concave portions on both sides of the H shape in advance. As for the remaining portion, the stud 7 is assembled to the beam 6 as described later, and then the lid member 10 is screwed and covered. This is to prevent grains from accumulating in the recesses of the beams 6 and the studs 7 when the grains are stored.

At the place where the beam 6 is attached to the main pillar 5,
A mounting plate 11 having a plurality of bolt insertion holes is protruded, and a plurality of bolt insertion holes are formed at each end of the beam 6 so as to correspond to the plurality of bolt insertion holes of the mounting plate 11. .

Therefore, the mounting plate 14 is formed such that the inner circumference of the frame is slightly larger than the outer circumference of the frame member 4 of the panel P for the frame portion formed by the main pillar 5, the stud 7, and the upper and lower beams 6. Is attached in a frame shape, and an attachment frame 15 having the same shape as the frame material 4 is attached to the attachment plate 14.
Is attached via a shim 16 by screw-type fastening means (bolts 17 and screw holes 14h) for fastening in the panel width direction, and the panel P is attached to the attachment frame 15 using the frame material 4. Therefore, even if the dimensions of the panel mounting frame formed by the main pillar 5, the studs 7, and the beams 6 vary, the panel P can be securely mounted.

Each of the silos S is configured to discharge stored grains to the outside from a hopper-type discharge part by natural flow. That is, as shown in FIGS. 6 and 7, the bottom of the silo S is formed in a funnel shape with a constriction, and a grain discharge port is formed at the tip thereof. It is configured such that the grains are discharged onto a lower horizontal conveyor (not shown) by natural flow.

Since each silo S is provided with the hopper type discharge section, empty spaces are formed below the silo S on both the left and right sides of the discharge section, as shown in FIG. , Each of the blowers 3
2 is arranged. In addition, by using such an empty space, a worker can use it as a passage for maintenance work.

[Another Embodiment] Next, another embodiment will be described. (B) In the above embodiment, the case where the reinforcing portion R is formed so as to include the vertical reinforcing portion and the horizontal reinforcing portion along the vertical and horizontal width directions of the panel when viewed in the panel thickness direction is illustrated. However, it may be configured to include only one of the vertical reinforcing portion and the horizontal reinforcing portion.
In this case, the cross-sectional shape of the rectangular tubular body T is formed in a square shape or a flat shape that is flat in the panel thickness direction, and such rectangular tubular bodies T are mutually connected to a plate portion for forming a reinforcing portion. With the Trs connected, they are juxtaposed in the panel width direction. In this case, the reinforcing portion R is composed of only the reinforcing portion forming plate portion Tr. However, since the interval between the reinforcing portion forming plate portions Tr is narrowed, the reinforcing portion forming plate portion Tr is formed. Reinforcement R in the direction perpendicular to
Without providing the panel, the strength in the panel thickness direction can be ensured.

(B) The specific configuration of the square tubular body T is not limited to the configuration exemplified in the above embodiment. For example, instead of the C-shaped member 1, two L-shaped members 21 each having a substantially L-shaped cross section are opposed to each other so as to form a closed space and are welded to each other as shown in FIG. You may.

(C) As shown in FIG.
Is a pair of rectangular plate members 22 arranged at an interval to form a pair of plate members B, and is located between the pair of rectangular plate members 22 to connect the pair of plate members 22. It may be configured to include a reinforcing member 23 for forming the reinforcing portion R.

(D) In the above embodiment, the case where both the pair of panel surface portions of the panel P are formed into a flat surface is exemplified. However, the panel surface portion that does not face the grain storage space is necessarily a flat surface. It is not necessary to form the shape.

(E) In the above-described embodiment, the case where two types of panels P having different strengths in the panel thickness direction are provided is exemplified. Only the same one type may be provided, or three or more types having different strengths in the panel thickness direction may be provided.

(F) In the above embodiment, the frame member 4 is attached around the panel P, and the frame member 4 is used to attach the panel formed by the main pillars 5, the studs 7, and the beams 6. Although the structure for assembling the frame P is adopted, the structure for assembling the panel P can be variously changed. For example, it is possible to employ a structure in which a mounting portion is provided intermittently around the panel P and extends outward from the panel, and the mounting is performed using the mounting portion. Alternatively, it is possible to adopt a structure in which the panel P itself is directly assembled without providing a mounting member such as the frame member 4 or the like.

(G) In the above embodiment, the case where the reinforcing portion R is reinforced so as to have the same strength in the entire panel width direction has been described.
Instead, the reinforcing portion R may be configured to be reinforced in a state where the strength is sequentially changed from one end side to the other end side in the panel width direction. This case is suitable for the case where one panel P is assembled vertically to form the side wall of the storage space.

A concrete structure for reinforcing the reinforcing portion R in a state in which the strength is sequentially changed from one end side to the other end side in the panel width direction is as follows. A configuration can be employed. That is, a plurality of types of rectangular tubular bodies T having different widths of the plate portions Tb for forming the plate-shaped portions are manufactured, and such multiple types of rectangular tubular bodies T are provided from one end side to the other end side in the panel width direction. Plate portion Tb for forming plate portion
Are preferably juxtaposed in the panel width direction so that the width of the panel changes sequentially. With this configuration, the interval between the reinforcing portions R sequentially changes from one end side to the other end side in the panel width direction, so that the reinforcing strength can be sequentially changed. Alternatively, a plurality of types of rectangular cylindrical bodies T having different wall thicknesses are juxtaposed in the panel width direction so that the wall thickness changes sequentially from one end to the other end in the panel width direction. You may. In this case, since the thickness of the reinforcing portion R in the panel width direction sequentially changes from one end side in the panel width direction to the other end side,
The reinforcement strength can be changed sequentially.

Further, a plurality of types of panels P whose strength is sequentially changed from one end side to the other end side in the panel width direction may be provided so that the average strength in the panel width direction is different. In this case, when attaching a plurality of panels P in the up-down direction, the panels P having lower average strengths are arranged upward.
