Description

  The present invention relates to a multistage plant cultivation shelf for cultivating plants such as fruits and vegetables indoors.

  In recent years, facilities for growing vegetables and the like on a large scale indoors are increasing. Such facilities are generally referred to as plant factories. Plant factories have the advantage of being able to grow plants stably by reducing the effects of weather and pests.

  Moreover, when building such a plant factory, the example which utilizes the facility used as a warehouse, a factory (for example, semiconductor factory) of a general manufacturer, etc. is known. This is because the construction cost of a plant factory can be reduced by using a facility such as a warehouse.

  Here, in a plant factory, in order to increase the yield as much as possible with a limited floor area, a multistage cultivation shelf may be used. As such a multistage plant cultivation shelf, for example, the one disclosed in Patent Document 1 below is known.

  In Patent Document 1, a rack-type plant cultivation shelf is constructed using a plurality of columns and beam members. Moreover, in order to carry in and out the cultivation container to and from the high level portion of the plant cultivation shelf that is out of the reach of workers, a lifting lift is installed.

JP 2014-132847 A

  In conventional multi-stage plant cultivation shelves, for example, steel posts and beam members are fixed with bolts or welding.

  However, if the number of columns and beam members is very large because the size of the plant cultivation shelf is very large, the work of fixing all the beam members to the columns by bolts and welding has a large work load. This will increase the construction cost of the factory.

  Also, when it is necessary to dismantle or relocate the plant cultivation shelf, such as when the plant factory is closed due to aging, etc., if the rod member is fixed to the column with bolts, welding, etc., the dismantling・ Relocation costs will be high. In particular, when building a plant factory in an old facility that was used as a warehouse (as described above), there is a possibility of closing the plant factory in a relatively short period of time. This is a very large management burden.

  In addition, in the plant cultivation shelf of Patent Document 1, a large-scale lifting lift is installed on the floor surface, and this also increases the construction cost and removal / relocation cost of the plant factory.

  Furthermore, in the plant cultivation shelf of patent document 1, when an operator wants to observe the cultivation container of a high level part directly, an aerial work vehicle etc. are needed. For this reason, not only the operation cost of the plant factory is increased, but also the work load such as the observation work is increased, and the worker is dangerous.

  An object of the present invention is to provide a multistage plant cultivation shelf that is easy and inexpensive to construct, remove and move, and that is easy and safe for workers to work.

  In order to solve such a problem, the invention of claim 1 is a multi-stage plant cultivation shelf in which a plurality of stages of cultivation floors are arranged in a substantially vertical direction, and a plurality of support columns extending in a substantially vertical direction are arranged on the installation surface. And having a frame structure in which a plurality of beam members extending in a substantially horizontal direction are installed between adjacent columns, and each beam member is provided with a wedge member provided on the beam member. By engaging with the wedge receiving member, it is locked to the support column, and on each of the cultivation floors, a plurality of cultivation tank support members are installed between the adjacent beam members, so that the plant cultivation tank One or a plurality of cultivation tank installation parts for placing the cultivar are provided.

  In addition to the structure of Claim 1, the invention of Claim 2 is adjacent to the cultivation tank installation part for each of the cultivation floors of a predetermined stage, and a passage part for an operator to get on and work on Is provided.

  According to a third aspect of the present invention, in addition to the configuration of the second aspect, the passage portion includes a scaffolding support member installed on the beam member, and a step board member installed on the scaffolding support member. It is characterized by.

  According to a fourth aspect of the present invention, in addition to the configuration according to the second or third aspect, a step portion for moving between the work passage portions at different steps is further provided.

  According to the first aspect of the present invention, a multi-stage plant cultivation shelf is configured using a frame structure using a column and a beam member, and when the beam member is installed on the column, the beam member wedge member is used as a column wedge. Since the structure is made to engage with the receiving member, the assembly and disassembly of the multistage plant cultivation shelf is very easy and inexpensive.

  According to invention of Claim 2, since the work channel | path part was provided for every cultivation floor of the predetermined | prescribed stage, even if it is the high stage part of this plant cultivation shelf, a worker can cultivate the cultivation state without using a lifting lift. It becomes possible to confirm directly and carry in and out the cultivation container.
