Description

  The present invention relates to a temporary structure used for installing a floor on a natural turf pitch and a temporary floor using the same.

  There is a stadium with a pitch using turf as a building for soccer and athletics. Some of these stadiums use natural turf due to the necessity and safety of the competition rules, or the feel during use. However, natural turf is difficult to grow because the growing state changes depending on the sunlight irradiation state and air permeability depending on the weather. Therefore, in order to grow natural turf, a method and an illuminating device for irradiating artificial light onto a pitch have been studied (for example, Patent Document 1).

  In the technique described in Patent Document 1, a partition floor is arranged via a removable support column at an interval above the ground where the lawn is grown, and the partition floor can be moved. Furthermore, an illuminating body is attached to the lower surface of the partition floor, and the lawn is irradiated with light having a wavelength band effective for photosynthesis, thereby ensuring controlled hot and humid air in the space between the ground and the partition floor. By irradiating the lawn with light having a wavelength range effective for photosynthesis, the photosynthesis of the lawn can be promoted even in the absence of sunlight.

  In the stadium, events such as concerts may be held in addition to sports such as soccer and athletics. In this case, in a stadium using natural turf, a curing member may be laid on the natural turf so that the natural turf is not damaged, and a stage and a spectator seat are detachably installed (temporary) on the turf. However, in this case, light and wind do not reach the natural turf, which may damage the natural turf. Moreover, a great effort is required to spread the curing member. Also in the growing device described in Patent Document 1, it takes time to arrange the growing device because the support for placing the partition floor is firmly attached.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a temporary structure that can easily install and remove a floor while reducing and nurturing natural turf damage. The provision of a temporary floor using

  A temporary structure that solves the above problem is a temporary structure that is installed on a pitch in which natural turf is planted, and a floor panel that is disposed at a height that ensures ventilation with the pitch. In order to move the support member onto the pitch, a support member having a truss structure that supports from below, an illumination mounting portion that attaches an illumination unit that irradiates artificial light to the pitch, and the support member. A moving member attached below the support member, and a fixing portion for fixing the floor panel is provided on an upper portion of the support member. Thereby, the temporary structure can be easily arranged on the natural grass using the moving member. Furthermore, after installation, an event or the like can be performed on the floor panel while cultivating the turf by irradiating the natural turf with artificial light while ensuring ventilation.

  In the temporary structure, the illumination attachment portion has a structure that can be expanded and contracted in a direction orthogonal to the extending direction of the support member, and the illumination attachment portion has a length of one side of the floor panel. It is preferred to extend to the corresponding length. Thereby, an illumination attachment part can be extended and the space | interval with an adjacent temporary structure can be ensured.

  In the temporary structure, it is preferable that a slide rail is used as the illumination mounting portion, and the illumination portion is provided on the slide rail. Thereby, since an illumination part can be efficiently extended and arrange | positioned widely, artificial light can be efficiently irradiated to natural turf with a simple structure.

  In the temporary structure, it is preferable to provide a blower member that blows air below the support member. Thereby, when turf is cultivated by artificial light, air flow is created around the natural turf by the blowing member, so that photosynthesis can be promoted and good turf can be cultivated.

  The temporary floor that solves the above-mentioned problem is that the temporary structure is juxtaposed in a direction perpendicular to the extending direction of the support member, and a floor panel is installed on the upper part of the support member of the adjacent temporary structure. hand over. Thereby, the temporary structure can be easily arranged on the natural turf using the moving member, and after the installation, the natural turf can be irradiated with artificial light to grow the turf.
