Description

The present invention relates to agricultural production building structure for performing the production of agricultural products in the building.

  Conventionally, for example, the production of agricultural products such as shiitake mushrooms, shimeji mushrooms, namametake, etc. requires temperature management because an optimal cultivation environment is required throughout the year. Therefore, various methods have been established in temperature management that can maintain a constant environment indoors.

  In general, in a building on the ground, for example, in a cultivation space where shiitake mushrooms are cultivated, it is hot in summer and the room temperature may be around 50 ° C., and it is difficult to lower it to an appropriate temperature even by using a cooling device. Moreover, even if it is cold in winter and can be raised to an appropriate temperature using a heating device, the cost of heating (air conditioning) increases significantly. Moreover, in such an air conditioning apparatus, the change of the humidity of cultivation space is also large, and in order to obtain the optimal humidity environment for agricultural products, the equipment which controls humidity further is required.

  For example, in the utilization method of the underground cave cold disclosed in Patent Document 1, a blower is used from the bottom of the underground cave where the temperature is constant and stable for the cultivation house where the internal temperature becomes high in summer. By sucking the cold air and sending the cold air, the house is going to be cooled.

  Furthermore, in the geothermal utilization structure disclosed in Patent Document 2, the thermal insulation wall in the summer is surrounded by the thermal insulation wall embedded in the underground constant temperature layer where the temperature fluctuation is stable. The heat energy from the solar heat that irradiates the ground surface is blocked from heat exchange that is taken into the building from the foundation through the ground, and the ground directly under the building is kept at a relatively low temperature relative to the building. Increases the cooling effect inside the building, and the insulation walls in winter prevent the thermal energy from being scattered through the foundation and escape to the ground around the building, thereby increasing the heating effect inside the building. Is.

  However, the use of underground cave cold air as shown in Patent Document 1 uses a blower to suck up the cold air from the bottom of the underground cave, so the air blower must be used at all times during cooling. Although the power consumption can be reduced as compared with the case of use, it is inevitable that the cost of power consumption due to the use of the blower is always generated.

  Moreover, in the geothermal utilization structure as shown in Patent Document 2, although the cost of power consumption does not always occur as in the method of using underground cave cold in Patent Document 1, the underground constant temperature layer where the temperature fluctuation is stable is underground. Since it is necessary to embed a heat insulating wall deeply, in order to implement the invention, both the cost and time of laying work are required. Furthermore, in the prior arts of Patent Documents 1 and 2, the cultivation space is generally used only on the ground, and the cultivation space tends to be narrowed by a multi-stage cultivation method such as shiitake.

In view of the aforementioned circumstances, an object of the present invention is not to cast high costs for air conditioning costs and laying is to provide a agricultural production building structure which can produce an optimum growing environment for the cultivation of agricultural products .

Means for Solving the Problems and Effects of the Invention

In order to solve the above problems, the agricultural product production building structure of the present invention is an agricultural product production building structure for producing agricultural products in a building, and is formed to a predetermined depth in the ground by excavating the ground. Excavation part, earth retaining member arranged so as to be exposed from the bottom surface of the excavation part to the ground, and earth pile formed by embedding soil at a predetermined height outside the ground exposed part of the earth retaining member And a roof that covers the top of the cultivation space formed by the earth retaining member, and enables cultivation of agricultural products in the cultivation space, and the earth retaining member is composed of a plurality of pillar materials and a plurality of plate-like wall materials. The pillar material is driven into the soil at the bottom of the excavation at a predetermined interval and depth along the excavation side of the excavation part, and the upper end thereof extends from the ground to reach the height of the roof, while the plurality of walls The material is in the form of straddling between adjacent columns, Similarly, in the portion extending from the ground surface toward the roof, the wall material is provided along the height direction of the pillar material so that the wall material is connected to the upper extension of the excavation side surface. The earthing portion is earthed so as to be in contact with the outside of the wall material, and the earth pressure of the earthing portion and the earth pressure on the side of excavation are received by the pillar material through the wall material .

Further, the column member is an H steel having two parallel wall portions that are H-shaped in cross section and opposed to each other and a connecting wall portion that connects the parallel wall portions at a right angle in the middle. The H steel is driven into the soil so that the parallel wall portion is parallel to the excavation side surface of the excavation portion, and the wall material is a rectangular plate defined by a short side and a long side and having a predetermined thickness, The plate is inserted into the space between the parallel walls of the H steel from both sides of the connecting wall, and the longitudinal ends of the plate are opposed to each other across the connecting wall of the H steel. In the form, a plurality of plates are stacked on each long side, stacked along the excavation side surface with the short side direction of the plate as the height direction, and the plate material passes from the bottom of the excavation part through the ground and further toward the roof The earth-filled part is earthed so as to be in contact with the outside of the plate material on the ground, and the earth pressure on the earth-filled part and the earth pressure on the side of the excavation are Together is received at H steel through the wood, the plate surface of the plate material from the excavation side of the two parallel walls on the inner surface of the parallel wall on the far side of the steel H is pressed by the earth pressure.

In addition, a plurality of pillar members that are opposed to each other across the space of the excavation part are connected in a lateral direction by a connecting beam, so that the connecting beam also connects the embankment part and the excavation side surface via the pillar material. It becomes a member that receives earth pressure, and the roof is supported on the upper side of these connecting beams and column members.

  In this way, the excavation part formed at a predetermined depth in the ground is in a semi-underground state surrounded by soil, and the above-ground part is surrounded by soil, for example, by the earthen part, so-called half It can be a cave-type (semi-underground) cultivation space. For this reason, since the room temperature is almost constant throughout the season, the summer is cool, and the winter is warm, the air-conditioning cost necessary for cultivation is greatly reduced, and the indoor cultivation cost can be reduced. Moreover, the humidity of the cultivation space is kept high by the semi-underground type, and it is less affected by the external environment. Therefore, it is possible to reduce the amount of water spray (water usage) for maintaining the humidity, the environment of the cultivation space is stable, and the cultivation management becomes easy.

  Also, more specifically about the semi-cave type (semi-underground type), the excavation part (underground) has a heat insulation effect that the outside soil is not easily transmitted by the underground soil in summer and the cold air is not easily transmitted in winter (cool in summer) You can also get warm in winter). In addition, since the earth retaining member or wall material is earthed with soil (embankment part), the ground part also has an inside room (cultivation space) due to the soil effect of the ground part as well as the excavation part (underground). Also, it is possible to obtain a heat insulating effect that is not easily affected by outside air such as hot air in summer and cold air in winter. The double temperature effect of “soil” between the underground excavation and the ground above, which is cool in summer and warm in winter, has a positive impact on the cultivation of agricultural products, and does not require or use air conditioning for heating and cooling. Can be significantly reduced, and the heating and cooling costs (air conditioning costs) can be significantly reduced. Therefore, this leads to a significant cost reduction of agricultural products.

  In addition, when using a part or all of the soil dug when forming the excavation part as a fill-up part that covers the ground part with soil, it is not necessary to carry soil from others, and Since it is not necessary to throw away everything, it is possible to reduce the amount of work and time, and there is no waste.

  Furthermore, since the cultivation space includes an excavation part and a ground part up to the roof, the present invention is similar to the conventional building (cultivation house or the like) because the excavation part (underground part) can be used. A lot of cultivation space can be secured even in the area. Therefore, more agricultural products can be produced than in the conventional building.

  In the present invention, the embankment is formed so as to be in contact with the earth retaining member or the wall material, and has a slope in which the stacked height decreases as the distance from the earth retaining member or the wall material increases.

  If it does in this way, adjustment with the amount of excavation of an excavation part and the amount of piles of a pile-up part becomes easy. Therefore, it is easy to form a banking portion around the wall material.

  In the present invention, the maximum height of the embankment is equal to or greater than the depth (D) of the excavation.

  If it does in this way, since all or many parts of the above-ground part are surrounded with soil from the outside among cultivation spaces, the heat insulation effect of the above-ground part which is easy to be influenced by outside air increases.

  The roof includes a set of metal plates arranged with a predetermined gap therebetween, the surface of which is a light and heat reflecting surface, and an insulating air layer or heat insulating material layer arranged between the metal plates, Light and heat from the outside are reflected on the outer surface of the outer metal plate.

  If it does in this way, the heat | fever of sunlight will be reflected with one set of metal plates of a roof, and it will be hard to escape the room temperature of a building outside by the air layer or heat insulating material layer in between.

  The earth retaining member functions as a pillar driven into the ground at a predetermined depth from the bottom surface of the excavation part, and a plurality of parallel cross-sectional sides of the H-shape are arranged so as to follow the wall surface of the excavation part. A plurality of retaining wall members assembled so as to connect adjacent ones of the plurality of H steels and to be inserted into an opening between the pair of parallel cross-section sides of the H steels. And the embankment part or the heat insulation wall part is formed in the ground exposed part of the earthen wall material.

  In this way, the H steel that functions as a pillar does not fall down due to the H-shaped shape even after being driven into the ground, and the earth retaining wall is inserted into the opening between the parallel cross-section sides. Even when materials are inserted, each can be firmly assembled to improve the overall stability.

  In the present invention, the bottom surface of the excavation part is formed with a gradient for drainage.

  If it does in this way, since the water of the bottom face of an excavation part will be drained by a gradient, even if rain water infiltrates into the bottom face of an excavation part, the stay will be prevented and the environment with good drainage can be maintained.

  Further, according to the present invention, an entrance / exit is formed in at least a part of the earth retaining member or wall material, and a slope is formed through the entrance / exit toward the bottom of the excavation part, and the slope has an inclination larger than the slope for drainage. .

  In this way, the steep step from the ground to the bottom of the excavated part at a predetermined depth is eased by the slope at the entrance and exit, so that the entrance and exit of vehicles, etc. accompanying the entry and exit of materials, etc. Can be done easily.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view illustrating an agricultural product production building structure 1 according to the present invention. FIG. 2 is a perspective view of FIG. FIG. 3 is a cross-sectional view showing only the excavation part 5 of FIG. 1. FIG. 4 is a cross-sectional view showing a state where the column member 8 and the wall member 9 are provided. FIG. 5 is an explanatory cross-sectional view illustrating the configuration of the column member 8, the wall member 9, and the roof 13 of the agricultural product production building structure 1 according to the present invention. FIG. 6 is a plan view with the roof 13 of FIG. 5 removed. FIG. 7 is an explanatory sectional view showing the gradient 20 and the slope 30 for drainage.

  1 and 2 show an agricultural product production building structure 1 according to the present invention. Agricultural production building structure 1 has a form that spans an excavation part 5 formed by excavating the ground, a plurality of column members 8 erected from an excavation bottom surface 6 of excavation part 5, and an exposed portion of adjacent column material 8 on the ground. The wall material 9 surrounding the excavation part 5 and forming the excavation part 5 and the cultivation space 11 formed above the excavation part 5, the embankment part 12 buried on the outside of the ground exposed portion of the wall material 9, and cultivation A roof 13 covering the upper side of the space 11 is provided, and the agricultural product 2 can be cultivated in the cultivation space 11. The column member 8 and the wall member 9 constitute an earth retaining member 19 (see FIG. 6), and are positioned higher than the ground surface from the bottom surface of the excavation unit 5 so as to surround the periphery of the excavation unit 5. A specific embodiment of the agricultural product production building structure 1 will be described below. Although not shown in the drawings, the agricultural production building structure 1 is based on the premise that foundation work for ensuring the safety of the building has been performed based on the Building Standards Law Enforcement Order.

  First, as shown in FIG. 3, a certain depth, for example, about 1.5 m (D) is excavated from the ground 3 to the underground 4, and the excavation part 5 is formed in the underground 4. The excavation bottom surface 6, which is the bottom surface of the excavation part 5, is leveled so as to be substantially horizontal with the ground, and the excavation side surface 7 that is the side surface of the excavation part 5 is perpendicular to the excavation bottom surface 6. . The height of the excavation side surface 7 is, for example, about 1.5 m (D). In other words, the excavation part 5 has a so-called semi-underground shape with a depth of, for example, about 1.5 m (D).

  As shown in FIG. 4 and FIG. 5, a plurality of pillar members 8 are erected from the excavation bottom surface 6 of the excavation part 5 that is leveled. It is assumed that the pillar material 8 is driven into the ground 4 to a depth of, for example, about 3 m. As the column member 8, a well-known architectural steel frame such as H-shaped steel is preferably used. The height of the column material 8 to be erected is determined as appropriate. For example, if the depth of the excavation part 5 is about 1.5 m (D), for example, about 3 m, the column material 8 is about 1 m to the ground. It will protrude 5m. Furthermore, an auxiliary column 22 that does not surround the excavation part 5 and a connecting column 23 that connects the column member 8 and the auxiliary column 22 are provided.

  Further, as shown in FIG. 6, plate-like wall materials 9 made of wood or metal having the same height and thickness as the pillar material 8 constituting the earth retaining member 19 are formed on the pillar materials 8 adjacent to each other. It is provided in a straddling form. In short, in a plan view, the wall material 9 is provided at a position between the pillar material 8 surrounding the excavation part 5 and an outer banking part 12 described later. Thereby, it becomes the form which surrounds the excavation part 5 with the wall material 9 and the pillar material 8. FIG. And the ground part 10 (refer FIG. 5) is formed above the excavation part 5 enclosed by the wall material 9 and the pillar material 8. As shown in FIG.

  The wall material 9 is not limited to wood or a metal material, and the wall material 9 can be constituted by a well-known building member such as a concrete block.

  Returning to FIG. 5, for example, a part of the soil generated when the excavation part 5 is formed is piled outside the ground exposed part of the wall material 9, thereby forming the earthing part 12. The raised portion 12 is formed so as to be in contact with the wall material 9 and has an inclination in which the stacked height (H) decreases as the distance from the wall material 9 increases. Therefore, the embankment 12 covers the wall material 9 exposed on the ground, and when the agricultural product production building structure 1 of the present invention is viewed from the outside on the ground, the wall material 9 is not visually recognized. In addition, while the pile height (H) of the embankment part 12 is made substantially the same as the depth (D) of the excavation part 5, it is also equal to the part (h) where the column material 8 protrudes on the ground.

  In addition, it is not always necessary to use the earth dug when forming the excavation part 5 for the embankment part 12, and when using temporarily, other cohesive soil etc. can be prepared and mixed suitably, for example. . Thereby, the soil quality can be adjusted to increase the viscosity, for example, and the embankment portion 12 can be easily formed.

  In addition, a roof 13 that covers the top of the cultivation space 11 is provided. The roof 13 has a pair of metal plates 25 arranged with a predetermined gap therebetween, and a heat insulating air layer (between the metal plates 25). Heat insulating material layer) 26. Specifically, for example, an aluminum plate is used as the metal plate 25, and the air layer (heat insulating material layer) 26 for heat insulation is made of, for example, synthetic resin polyethylene or the like, and a bag shape in which air is sealed in a number of cells. A member (air cell sheet) is used. Thereby, light and heat from the outside are reflected by the outer surface of the outer metal plate 25, and the air layer (heat insulating material layer) 26 makes it difficult to release the room temperature inside. Further, for example, a general gable roof made of wood (a roof in which two inclined surfaces have a mountain shape from the ridge at the top of the roof toward the ground) is also suitable.

  Using the cultivation space 11 described above, an agricultural product 2, such as shiitake mushroom, can be produced as shown in FIG.

  As shown in FIG. 7, the agricultural product production building structure 1 has a drainage gradient 20 formed on the excavation bottom surface 6 of the excavation part 5. This gradient 20 may be, for example, an inclination of about 1 °. As a result, for example, rainwater or the like on the bottom surface 6 of the excavation part 5 is drained.

  Further, a part of the wall material 9 (the earth retaining member 19; see also FIG. 6) is opened and an entrance / exit 15 is arranged, and for example, as an example, a pair of right / left triangular doorways from the wall material 9 beside the entrance / exit 15 A wall 16 (see FIG. 2) provides a passage to the entrance 15. Furthermore, a slope 30 is formed in the passage between the entrance wall 16 and passes through the entrance 15 to the excavation bottom surface 6 of the excavation unit 5. The slope 30 has an inclination larger than the slope 20 for drainage. Specifically, the inclination is, for example, about 10 °, and the entrance / exit 15 has an excavation part 5 having a depth of about 1.5 m from the ground. A steep step up to the excavation bottom surface 6 is alleviated by the slope 30.

  The cultivation space 11 is not normally used, but is provided with an air-conditioning facility 40 (see FIG. 1) to cope with abnormal weather, and it is possible to assist temperature / humidity management in the cultivation space 11. It is.

  Next, an example of a work process accompanying implementation of the agricultural product production building structure 1 as described above will be described.

This excavation work also serves as a preparation for the remaining soil treatment associated with the excavation work of the ground 3 and the formation of the embankment portion 12 using the discharged soil 18 later. Thereafter, the bottom surface of the excavation part 5 is used as the excavation bottom surface 6 and the ground is leveled so as to be substantially horizontal with the ground 3.

<An example of column / outer wall driving process>
Then, as shown in FIG. 4, for example, a plurality of H-shaped steel pillars 8 having a height of about 3 m are driven onto the excavation bottom surface 6. The pillar material 8 is driven into the excavation bottom surface 6 to a depth of 3 m, for example. Instead of the column member 8, a pile made of, for example, wood having a sharp tip can also be applied. Then, the column member 8 is driven into a slightly inner side of the excavation side surface 7 of the excavation part 5 so that a gap equivalent to the thickness of the wall material 9 is formed. Then, as shown in the enlarged view of FIG. 4, a plurality of, for example, six pieces of wall material pieces 9 ′ made of, for example, wood or metal material are dropped from above into the gap, and the wall material having the same height as the column material 8. 9 is formed.

In addition, the auxiliary pillar 22 is applicable also by well-known H steel etc., for example. And each of the pillar material 8 and the auxiliary | assistant pillar 22 is connected with the connection pillar 23 (refer FIG. 5, 6). The connecting column 23 can be expected to increase the strength of the column member 8 and the auxiliary column 22 in the front-rear and left-right directions, and can also be used as a crossbar for supporting the weight of the roof 13, that is, a beam.

  Further, a part of the wall material 9 surrounding the excavation part 5 is not provided with the wall material 9, and the entrance walls 16 and 16 are set to be equal to the interval between the auxiliary columns 22 driven in two rows. Are provided to form the entrance / exit 15 (see also FIG. 2). If it carries out like this, even if a car etc. enter into cultivation space 11 from entrance / exit 15, since the arrangement interval of auxiliary pillar 22 and entrance / exit 15 is made the same, it can move (in / out) smoothly. In addition, when the shape of the entrance / exit wall 16 is, for example, inclined from the installation surface toward the upper roof to form a right triangle, a wider field of view can be secured when entering and exiting than a rectangular shape, and the design surface Is also excellent.

<An example of the process for forming the earthen section>
Returning to FIG. 5, for example, by using the discharged soil 18 accumulated in the vicinity of the edge of the ground 3 along the excavation part 5 obtained in the example of the excavation work process described above, the outside of the ground exposed portion of the wall material 9. In addition, it is inclined and piled up so as to become lower as it goes away from the wall material 9 (burial portion 12). Note that the embankment 12 does not necessarily use the discharged soil 18.

<Example of roof mounting work process>
