Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can fix a transparent sheet made of synthetic resin stretched on a framework in a pipe house as a greenhouse in which a framework is composed of a large number of arched pipes, etc. The present invention relates to a sheet fixing device capable of collecting the formed water droplets and discharging the water to the outside, and a dew condensation collecting device using the fixing device.

[0002]

2. Description of the Related Art Generally, a pipe house, which is used as a greenhouse for cultivation, has a large number of arched pipes standing on the ground, and a sheet fixing device is laid between the pipes in the lateral direction. The transparent sheet made of synthetic resin stretched on is fixed by a sheet fixing device.

This sheet fixing device is widely known in the industry as "Vinipet (registered trademark)", and it has an opening composed of a horizontal lower portion and a pair of support frames standing inward from both sides of the lower portion. It is composed of a dovetail groove frame having a narrow width and an elastic locking line that fits in the dovetail frame, and the sheet is pushed into the dovetail frame by the locking line to fix the sheet.

In a recent pipe house using such a fixing device for a sheet, it is required to treat water droplets condensed on the inner surface of the sheet. In this case, the water droplets attached to the sheet fall on the soil in the house. Then, the roots of the plants are rotted, causing diseases, poor growth, and poor greenhouses. Therefore, it is required to collect water droplets before they drop onto the soil and discharge them outside the house.

For this reason, recently, a dew condensation collecting device has been attached to a sheet fixing device, and for example, a device disclosed in Japanese Patent No. 3004565 has been developed.

According to this device, the fixing device has the first and second dovetail frames in the upper and lower two stages, and usually the second dovetail frame itself is arranged above the roof of the house or the like. This is used as a gutter for collecting dew condensation.

On the other hand, there is a case where the second dovetail frame is arranged on the lower side at a vertical position such as the side surface of the house, and in this case, the second dovetail frame and the horizontal bottom rear surface of the upper dovetail frame are used. The dew condensation is collected and drained by utilizing the V groove formed by the lower dovetail groove frame and the upper surface of the support frame as a trough.

[0008]

However, the above-described conventional sheet fixing device and the dew condensation collecting device using the same are not particularly defective in function, but have the following problems.

That is, when the mounting structure is such that the second dovetail frame is arranged on the upper side on the roof side of the house, the condensed water flowing from the rear surface of the upper seat as described above is the second dovetail. Although the groove frame can be used as a gutter, it can be collected, but if the mounting structure is such that the second dovetail frame is located on the lower side at the same position, there will be no gutter and the condensed water will hit the back of the first dovetail frame and remain in the house. There is a problem that it falls into.

On the other hand, when the condensed water can be collected even if the second dovetail frame is arranged on the lower side, as described above, the sheet fixing device is arranged at the vertical position which is the side surface of the house, and the lower sheet fixing device is arranged. This is the case when the second dovetail frame is used as a fixing frame for a ventilation sheet.

In this case, the V groove formed by the horizontal bottom rear surface of the first dovetail frame and the upper surface of the support frame of the second dovetail frame is used as a trough to collect the dew condensation and to be directly exposed to the outside. Can be discharged.

However, if it is installed at a position like the roof side of the house and is similarly attached to the sloping and gentle part of the arched pipe, the first and second dovetail frames cannot stand upright, As a result, the above V groove is inclined and faces the ground side, and does not function as a gutter.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a sheet fixing device capable of surely collecting condensed water regardless of whether the first and second dovetail frames are arranged upside down or a condensed water collecting device using the fixing device. It is to provide a device.

[0014]

In order to achieve the above-mentioned object, the means of the sheet fixing device of the present invention comprises a first dovetail frame having a narrow opening, and a diagonally lower part of the first dovetail frame. The first and second dovetails are composed of a second dovetail frame with a narrow opening and a resilient locking wire that fits into one or both of the first and second dovetail frames. The groove frame is composed of a pair of first and second sheet supporting pieces that stand obliquely inward from both ends of the horizontal bottom portion, and the second dovetail groove frame is provided with a pair of first and second sheet supporting pieces. A gutter frame, which is integrally connected near the lower end of one dovetail frame and stands upright in the opposite direction to the second dovetail frame on the back surface or near the back surface of the horizontal bottom of the first dovetail frame. It is assumed that water droplets formed on the inner surface of the sheet are collected by the gutter frame.

In this case, the gutter frame is preferably formed to have an L-shaped cross section.

Similarly, the means of the dew condensation collecting device comprises a fixing device for two sheets arranged in the longitudinal direction and a joint for connecting the fixing devices for the respective sheets, and the fixing device for the sheet has a narrow opening. The first dovetail frame, the second dovetail frame with a narrow opening, which is installed diagonally below the first dovetail frame, and one or both of the first and second dovetail frames. The first and second dovetail frames are composed of a pair of first and second sheet support pieces that stand up diagonally inward from both ends of the horizontal bottom portion. The dovetail frame of the first dovetail frame is integrally connected to the lower end of the first dovetail frame through one of the first sheet supporting pieces, and the rear surface or the back surface of the horizontal bottom of the first dovetail frame is formed. Form a gutter frame standing in the opposite direction to the second dovetail frame in the vicinity, The int has a horizontal bottom part and holding parts provided at both ends of the bottom part.The two adjoining fixing devices are connected to each other through joints, and the gutter frame rotates water droplets condensed on the inner surface of the sheet. , It is assumed that the water droplets collected through the joint are discharged to the outside.
