Description

The present invention relates to greenhouses such as agricultural greenhouses, and more particularly to greenhouses having block walls.

Today, greenhouses such as greenhouses are widely used for cultivation and cultivation of agricultural products.
This greenhouse such as a vinyl house has many advantages such that damages due to rain, wind, and pests can be reduced, and temperature changes due to seasons can be reduced to enable year-round cultivation.

However, while vinyl greenhouses are relatively easy to install, they are vulnerable to strong winds, the room temperature is lower than the optimum temperature in winter, and the room temperature is too high in summer, so it is not enough depending on the climatic conditions of the installation site. In some cases, it was not possible to take advantage of that advantage.

For this reason, various improvements and additions of auxiliary equipment have also been made to the vinyl house. For example, the roof is reinforced by using vertical beams and horizontal beams, and a closed space is formed in the roof part. A proposal has been made to introduce outside air, which is once stored and temperature-controlled in a closed space, into a greenhouse (for example, Patent Document 1).

In addition, the pipes from the hot water tank of the boiler shall be placed on the floor of the greenhouse.In the winter, the hot water from the boiler is circulated to the pipes placed on the floor, and in the summer, from outside the system. There is also a proposal to supply cold water to the pipe (for example, Patent Document 2).

Furthermore, in order to improve heat retention while facilitating assembly and installation, a partition sheet incorporating a hanging string is placed in a vinyl house covered with an outer sheet, and a hanging tool is hung on the hanging string to stretch a multi-layered sheet. A proposal has been made (for example, Patent Document 3).

Also, in order to make the greenhouse strong against strong winds, form a bag at the end of the sheet that covers the main pillars installed at appropriate intervals, and put water in this bag or insert a steel bar etc. There is also a proposal to bury it in the ground (for example, Patent Document 4).

Conventional greenhouses such as greenhouses have a drawback that maintenance costs such as fuel costs increase when a boiler or the like is used for heating in winter. Further, when the temperature becomes higher than expected, such as during the daytime in summer, the ventilation volume is increased according to the weather conditions, and it is troublesome to adjust the indoor temperature of a greenhouse such as a greenhouse.

Further, in a vinyl house, preparations such as strengthening the framework of the house have sometimes been required to withstand strong winds and the like.

The present invention provides a greenhouse such as a vinyl greenhouse that can reduce such drawbacks, save heating costs in winter and reduce temperature changes day and night, and can increase resistance to bad weather. ..

A greenhouse according to the present invention is a greenhouse formed by attaching a vinyl sheet or a transparent plate to a framework of columns, girders, and roofs, and forming a ceiling and side walls, and a front wall such as a gabled face having an entrance/exit, in a house. The floor surface is made of tuff, and the greenhouse is formed with a tuff stone wall at least in the lower half of the side wall.

The stone wall may be a greenhouse in which blocks of tuff are piled up in a house along the side wall, and a stone wall having a heat insulating material layer on the outer surface of the block wall.

Further, the stone wall is a greenhouse in which blocks of Otani stone are stacked, cold and hot water pipes are arranged on the inner surface of the block wall, and a stone plate of Otani stone is further attached to the inner surface of the block wall. There is also.

And, the stone wall, blocks of Otani stone are stacked, cold and hot water pipes are disposed on the inner side surface of the block wall, and chips of Otani stone are disposed on the inner surface of the block wall on which the hot and cold water pipes are disposed. It may be a greenhouse with a plastered wall made of powder or stone dust and plaster.

In addition, the floor surface in the house may be a greenhouse which is a block floor of Otani stone or a compaction bed of chips and stones of Otani stone.

And, the floor surface in the house, hot and cold water pipes are arranged on the floor surface of the compacted bed of chips and debris of Otani stone, and Otani stone on the floor surface where this cold and hot water pipe is arranged. It may be a greenhouse with a block floor laid out so that the blocks are lined up.

In addition, the floor surface in the house may be a compaction bed of chips of Otani stone and debris, and a hot and cold water pipe may be provided inside the compaction bed.

Then, the ground surface in the house is shaved to form a rolling bed of chips and debris of Otani stone, and a block floor is laid so that blocks of Otani stone are lined up on the upper surface of this rolling bed. A hot and cold water pipe may be installed on the upper surface of the block floor, and a greenhouse may be constructed by laying Otani stone slabs on the block floor.

In addition, the ground surface in the house may be dug down by 1 m to 2 m, and a semi-underground house using tuff on the floor surface and the lower part of the house side surface may be used as a greenhouse.

The stone wall may be a greenhouse having a height of 30 cm to 50 cm from the ground surface and having a heat insulating material layer on the outer surface of the above-ground portion.

Further, the stone wall is a block wall by a block product of Otani stone, and on the outside of the block wall below the ground surface, a greenhouse in which a layer of chip dust or stone chips of Otani stone is formed between the earth and the earth. There are also things to do.

The pillars, girders, and roof skeletons may be greenhouses made of wood.

Greenhouses such as the greenhouse according to the present invention, by making the lower part of the floor surface and the side surface tuff, to suppress the temperature rise during the daytime due to the hygroscopicity, thermal insulation, etc. of the tuff, and at night, etc. It is possible to prevent the decrease and reduce the load of artificial cooling and heating. Further, by making the lower half of the side wall of the greenhouse a stone wall, it is possible to make the greenhouse strong against strong winds and the like.

Since the stone wall is used as the block wall and the heat insulating material layer is provided on the outer surface of the block wall, it becomes easy to keep the inside of the house at an appropriate temperature by reducing the influence of the outside temperature.

Also, since Otani stone blocks and stone plates are used as stone walls, construction of the block walls and construction of cold/hot water pipes on the inner surface are facilitated, and cold/hot water pipes are provided on the inner surface of the block wall. The temperature inside the house can be easily adjusted through the stone plate.

By forming a coating wall containing Otani stone blocks and Otani stone debris, etc., construction of the block wall and construction of cold/hot water piping on the inner surface can be facilitated, and the inner surface of the block wall can be cooled and heated. By providing the water pipe, the temperature inside the house can be easily adjusted through the coating wall containing the debris of Otani stone.

Further, if the floor surface is a block floor made of Otani stone, the construction is easy, and if a rolling bed of Otani stone debris or the like is used, the construction can be facilitated and the house construction cost can be reduced.

And the floor where the hot and cold water pipes are placed on the compacted floor of the debris of Otani stone and the blocks are spread, the layer of Otani stone is thickened at low cost, and the hot and cold water pipes can be easily arranged. The temperature inside the house can be easily adjusted.

Further, the floor surface having the hot and cold water pipes provided therein as a rolling bed for the debris of Otani stone can be easily and inexpensively constructed.

Then, in a floor in which blocks are laid on a compressed bed of debris of Otani stone and cold and hot water pipes are provided to arrange stone plates, the Otani stone layer can be easily thickened.

When the ground surface is dug down by 1 m to 2 m, the height of the greenhouse can be reduced to make it a strong house against strong winds and the like, and the difference in temperature between cold and warm due to geothermal heat can be made small.

If the height of the stone wall above the ground is 30 cm to 50 cm, it is possible to reduce the above-ground height while ensuring the height inside the house, enhance the resistance to strong winds, and reduce the influence of the outside temperature. ..

Furthermore, by forming a layer of Otani stone debris on the outside of the block wall in the underground portion, it becomes easier to stabilize the temperature in the house while utilizing the geothermal heat and the like.

If the framework of the greenhouse is made of wood, the temperature inside the house can be made more stable.

Sometimes it is a covered vinyl house 10.

In this vinyl house 10, Otani stone blocks 33 are piled up inside the pillars 11 forming the left and right side walls 61, and a block wall with a height of about 1.5 m is constructed along the inside of the left and right side walls 61. To do.

Further, a heat insulating material layer 41 such as urethane foam or expanded polystyrene board is formed on the outer surface of the block wall, and the outer surface of the heat insulating material layer 41 is protected by a plywood 51 such as a plywood board to form a stone wall 31. The house vinyl sheet 21 is attached so as to cover the house frame so as to cover the house frame.

Then, when the heat insulating material layer 41 is provided on the outer surface of the block wall, an end member 43 is provided at the lower end of the heat insulating material layer 41, and the middle portion of the heat insulating material layer 41 is appropriately divided according to the height of the heat insulating material layer 41. The material 45 is arranged, and the upper frame material 47 is arranged on the upper end of the heat insulating material layer 41 so as to cover the outer surface of the stone wall 31 with the plywood 51, and the heat insulating material layer 41 is arranged on the outer surface side of the block wall. It is arranged and formed.

When a heat insulating board is used as the heat insulating layer 41, the end member 43, the separating member 45, the plywood 51, etc. may be omitted.

The block 33 of Otani stone, which is a tuff when constructing this stone wall 31, has a thickness of 15 cm and a height of 150 cm using a general Otani stone block having a thickness of 15 cm, a width of 30 cm, and a length of 90 cm, for example. The heat insulating material layer 41 has a thickness of about 5 to 10 cm.

Then, the ground surface 85 in the house is laid with cutting powder and debris of Otani stone, and rolling is performed to form a compaction bed by debris 37 of Otani stone to a thickness of about 20 to 30 cm. By placing vinyl hoses and the like on the surface of the floor in a meandering manner and arranging the hose on the entire surface of the floor, a cooling and heating pipe 55 is formed, and a block 33 of Otani stone is laid on this to form a block floor.

Further, the cooling/heating pipe 55 such as a vinyl hose is also arranged on the inner surface of the block wall which is the stone wall 31 so as to be parallel to the meandering or horizontal direction, and inside the block wall where the cooling/heating pipe 55 is arranged.

Inside the vinyl house 10, a plurality of shelves 71 each having a height of about 1 m on which a medium shelf 73 containing a culture soil 75 is placed are arranged in a plurality of rows to grow an appropriate plant. The heat radiation pipes 79 for the medium are arranged on the lower side, the side surface of the medium shelf 73, etc., as in the conventional general high-rise cultivation greenhouse.

In addition, without using the shelf 71, the medium shelf 73 is suspended from the ceiling 63 so as to be floated about 1 m from the floor surface in the house, so that a suitable heat radiation pipe 79 for the medium is provided on the floor surface as a hanging shelf. There are also things to do.

Further, this vinyl house 10 has a ventilation fan 67 above the front wall 65 and also forms a gable face (front wall 65) having a doorway (not shown), similar to the conventional large-sized greenhouse 10. is there.

Note that the medium heat-dissipating pipe 79 arranged below the shelf 71 or on the medium shelf 73 may be omitted.

Then, the tuff stone wall 31 having the heat insulating material layer 41 on the outer side and arranging the cooling/heating pipe 55 inside is not only the lower half part of the left and right side walls 61, but also the front wall 65 excluding the entrance/exit part. It is preferable to construct in the lower half.

As described above, the greenhouse 10 according to the present embodiment has the stone wall 31 of Otani stone, which is tuff, on at least the lower half of the side wall 61, and the block 33 of Otani stone and debris are also provided on the floor surface in the house. Etc. 37 is used.

This tuff has a large number of voids of about 10 μm inside, and has a slight water absorption property. When the ambient temperature such as the ambient temperature decreases, the water content increases without forming water drops on the surface. When the ambient temperature rises, the water contained in the rock is vaporized to reduce the increase in the rock temperature, and the temperature has little temperature change with respect to the ambient temperature.

The tuff has a smaller heat transfer coefficient than metals and plastics and is close to wood, and it is possible to reduce the temperature change of the floor in the house and the stone wall 31 against the temperature change of the surroundings, and When a temperature difference occurs, cold air or warm air can be radiated into the house by radiant heat.

For this reason, it is easy to keep the temperature of the floor in the house and the lower half of the side wall 61 constant with respect to changes in the outside temperature and the temperature in the house, and in the summer, etc. By flowing water or the like, the height of the stone wall 31 in the house, that is, the rise in the temperature in the house up to the position height of the plant to be cultivated on a high shelf is suppressed, and damage to the cultivated plant due to an abnormally high temperature is performed. It can be prevented.

Further, in the winter, etc., by flowing hot water through the hot/cold heat pipe 55, the floor in the house and the lower portion of the side wall 61 can be warmed, and the heat insulating material layer 41 is provided on the outer surface of the stone wall 31. By reducing the influence of the outside air temperature and radiant heat from Otani stone that forms the stone wall 31, it is possible to keep the cultivated plant at an appropriate temperature while reducing expenses such as heating expenses.

Furthermore, the vinyl house 10 is constructed by using tuff for the floor in the house and the lower half of the side wall 61, and the house frame is constructed of wood. It is possible to evaporate the contained water to reduce the temperature rise of the floor, the wall, and the pillars 11, and to reduce the temperature rise in the greenhouse 10, and it is possible to suppress the occurrence of abnormally high temperatures during the day. ..

In addition, in the second embodiment shown in FIG. 2, as the floor surface in the house, the ground surface 85 is sprinkled with cutting powder of Otani stone, stone debris 37, etc. The block 33 of Otani stone is spread, the hot and cold pipes 55 are spread, and the stone plate 35 of Otani stone thinner than the block is spread.

Furthermore, in the third embodiment shown in FIG. 3, cutting powder of Otani stone, stone debris 37 such as stone debris, etc. are spread as the floor surface in the house, and a cold/heat pipe 55 is provided in the layer of the stone debris 37. A permeable sheet such as canvas or thick non-woven fabric is installed as a protective sheet 59 on the upper surface of the stone debris 37.

In this case, it is possible to reduce man-hours and costs when constructing the vinyl house 10.

Further, as shown in FIG. 4, the stone plate 35 provided inside the block wall is omitted and the protection sheet 59 is extended to the upper end of the stone wall 31, and the hot and cold pipes 55 are arranged inside the floor by debris 37. Along with setting up, the cooling and heating pipes 55 are also applied to the inner surface of the stone wall 31 within the range up to the lower half of the stone wall 31, and the cultivation soil 75 is spread in the house until the cooling and heating pipes 55 are filled up with cultivated plants. Sometimes I try to plant it.

In this way, the debris 37 of Otani stone, which is tuff, is used on the floor surface of the vinyl house 10, and the lower half of the side wall 61 of the vinyl house 10 is the stone wall 31 of Otani stone, which is tuff. The vinyl house 10 can reduce the temperature difference between daytime and nighttime in the house, reduce abnormal high temperature in the summer, and reduce temperature decrease in the winter, and maintain the constant temperature and heat of the Otani stone, which is tuff. By reducing the heating cost in winter etc. by radiating cold heat and reducing the number of steps for temperature adjustment, the lower half of the side wall 61 is the stone wall 31, so the vinyl house 10 can withstand strong winds and bad weather. is there.

Not only when the vinyl sheet 21 is attached to the house frame, a transparent plate such as an acrylic board or a glass plate is attached to the house frame as a greenhouse for cultivation, and Otani stone is used on the floor surface of the greenhouse and the side surface of this greenhouse. In some cases, the stone wall 31 of Otani stone may be constructed in the lower inner portion of the wall 61 or the lower inner portion of the front wall 65.

Also in this case, it is possible to effectively prevent the inside of the house from becoming high temperature or low temperature and save the cooling and heating costs as in the case of the greenhouse 10, and to make the temperature suitable for plant growth, and the resin plate. It is possible to make the cultivation greenhouse more resistant to bad weather such as strong winds than the greenhouse 10 by using.
