Description

The present invention relates to a round pipe house with an eaves, which is constructed by coating a skeleton structure with a vinyl sheet.

A vinyl greenhouse is a simple building in which a frame structure composed of a plurality of round arch pipes or the like is coated with a sheet material made of synthetic resin such as a vinyl sheet, and is mainly used for agricultural crop cultivation. A greenhouse protects crops from wind, rain, and snow, and can promote the growth of crops due to its heat-retaining effect.

On the other hand, in such a greenhouse, when the room becomes hot and humid, it generally causes poor growth of agricultural products and diseases. Therefore, in order to suppress an excessive temperature rise during the daytime and to reduce the humidity raised by the water vapor evaporated from the soil surface, ventilation is performed to exchange the outside air with the inside air. Ventilation can also promote carbon dioxide replenishment indoors and gas exchange within the cultivated crop community.

Conventionally, ventilation of a vinyl house is performed by winding up a vinyl sheet that covers the side of the vinyl house. Regarding such ventilation work, Utility Model Registration No. 3027395 proposes an invention relating to a ventilation device for a greenhouse / vinyl house in which the work of winding up a vinyl sheet accompanying ventilation can be automatically performed by a motor having a deceleration function. (Patent Document 1).

However, in the invention described in Patent Document 1, when the outside air temperature becomes zero degree or less, rainwater, condensed water, etc. freeze and stick to the vinyl sheet, and when the vinyl sheet is automatically wound up, the vinyl sheet is stretched. There is a problem that the vinyl sheet is damaged by getting the attached ice caught.

In addition, if there is rainfall during ventilation, the rainfall may enter the room and wet the soil. Therefore, the opening width for automatic winding must be set narrow, and there is also a problem that sufficient ventilation cannot be performed.

By the way, in areas where there is a lot of snowfall, snow falling from the roof accumulates at the hem of the greenhouse. If this accumulated snow is left unattended, the weight of the snow may damage the hem of the vinyl sheet or deform the skeleton structure. For this reason, a rotary type snowplow has been conventionally used to remove snow accumulated on the hem. However, there is a problem that the rotary of the snowplow and the endless track that drives the snowplow involve the vinyl sheet and the string that holds the vinyl sheet, the so-called house band.

The present invention has been made to solve the above problems, such as reducing the blowing of rainfall into the room through the ventilation opening on the side of the greenhouse, and snow at the hem of the greenhouse. It is an object of the present invention to provide a round pipe house with an eaves, which can reduce the accumulation of ice and suppress the formation of ice due to rainwater, dew condensation, etc. on the side.

The round pipe house with an eave according to the present invention reduces the inflow of rainfall into the room from the ventilation opening on the side of the vinyl house, and also drops snow, rainwater, and dew condensation water that slide down from the roof to a position away from the hem. In order to solve the problem of making the pipes, a plurality of round arch pipes are arranged side by side in parallel, and these are connected by a ridge pipe and a furring strip pipe to form a skeleton structure and covered with a vinyl sheet. A round pipe house, the curved shoulder portion formed above the straight pipe portion in the round arch pipe, or the furring strip pipe provided on the shoulder portion is formed in a curved shape in the eaves direction. The eaves arch material bulging out is fixed in a state where the maximum bulging portion protrudes outward from the hem of the round arch pipe, and the eaves of the round arch pipes arranged side by side. The arch materials are connected to each other by a beam material for eaves that is long in the depth direction, and the vinyl sheet is covered via the outside of the arch material for eaves.

Further, as one aspect of the present invention, in order to solve the problem of preventing rainwater and dew condensation water flowing down from the roof portion from being transmitted to the side portion, the position below the maximum bulging portion of the arch material for each eaves. Is provided with a draining member formed in a long shape in the depth direction, the draining member is connected to the arch material for each eaves, and the upper surface of the draining member is directed downward and outward as a draining surface. May be tilted.

Further, as one aspect of the present invention, in order to solve the problem of discharging the dew condensation water flowing down along the inner surface of the vinyl sheet of the roof portion to the outside of the house, the vinyl sheet is at least of the round arch pipe. A pair of left and right lower sheets that cover from the hem to the lower part of the maximum bulging portion of the eaves arch material, and at least the roof portion of each round arch pipe from the lower part of the maximum bulging portion of the eaves arch material. It is composed of an upper sheet that covers up to the ridge portion, and the lower end edge portion of the upper sheet may be overlapped and fixed to the outside of the upper end edge portion of the lower sheet.

Further, as one aspect of the present invention, in order to solve the problem of facilitating the fixing of the draining member and the vinyl sheet, the vinyl sheet may be fixed by the draining member.

According to the present invention, it is possible to reduce the inflow of rainfall into the room through the ventilation opening on the side of the greenhouse, reduce the accumulation of snow on the hem of the greenhouse, and use rainwater, condensed water, etc. on the side. It is possible to suppress the formation of ice.
