Description

  The present invention relates to a door for a vinyl house.

  Conventionally, an agricultural vinyl house constructed by stretching a sheet made of a resin film between a plurality of metal pipe-like bone members is known. In such a vinyl house, for example, resin on a roof portion or a side wall is used. There was a film in which the film was doubled and the heat insulation effect was enhanced by an air layer formed between the inner and outer films.

For example, at least a part of a roof or a side wall is covered with a double film, air is blown into a gap between the double films by a blower to form an air layer, and an exhaust hole communicating with the air layer is provided. Some holes have a valve body that opens when the pressure in the air layer exceeds a predetermined value (see, for example, Patent Document 1).
JP 2005-269963 A

  However, as described above, although it has been proposed that the vinyl house has a double film structure, there is no door having a double film structure for the door provided in the vinyl house.

  Even if it is going to apply the prior art, in the structure like the said patent document 1, a structure becomes too complicated and it is almost impossible to apply to a door.

  Moreover, since the door is normally provided inside the house wife surface, it has not been easy to make a double-tensioned film structure without hindering the opening and closing of the door.

  An object of this invention is to provide the door for vinyl houses which can solve the said subject.

  (1) The present invention according to claim 1 is a door for a vinyl house that is slidably attached to an entrance / exit of a vinyl house, and comprises a rectangular frame by combining bone members, and an outer surface of the vertical frame In addition, the outer resin film is stretched by a predetermined film fixing means, and a groove hole portion extending in the longitudinal direction is formed on the inner surface of the bone member, and the groove hole portion is connected to the groove hole portion. A film holding plate for holding and holding the resin film between them was attached, and the inner resin film was stretched to form a double-tensioned film structure.

  (2) The present invention according to claim 2 is characterized in that, in the door for a vinyl house according to claim 1, the bone member on which the inner resin film is stretched is a vertical frame constituting the frame. To do.

  (3) A third aspect of the present invention is the door for a vinyl house according to the first or second aspect, wherein the film pressing plate includes a pair of leg pieces and the leg pieces that fit into the groove portions. And connecting the base ends of the parts to each other, and having a cover part with a distal end extending outwardly of each leg piece part, the leg piece part being formed at a side edge of the slot part, and the bone member An engaging portion that engages with a convex end edge that protrudes to the inner side is formed.

  (4) The present invention according to claim 4 is the door for a greenhouse according to claim 3, wherein the first and second distraction end portions are respectively extended outward at the left and right edge portions of the cover portion. An end portion is formed, and the second extending end portion is formed in a step shape higher than the center of the cover portion, and is formed longer than the first extending end portion.

  (5) The present invention according to claim 5 is the vinyl house according to claim 3 or 4, wherein the cover portion of the film pressing plate is a slot portion in which the film pressing plate is formed on the inner surface of the bone member. The protrusion thickness from the said inner surface was stored in the range of 0.5-2.0 mm in the state fitted to.

  ADVANTAGE OF THE INVENTION According to this invention, the door for vinyl houses which was difficult to set it as a film double tension structure conventionally can be made into a film double tension structure easily and cheaply, and the heat insulation effect of a house can be improved more.

  The present invention is a door for a vinyl house that is slidably attached to the entrance and exit of a vinyl house, is configured by combining a bone member to form a rectangular frame body, and a predetermined film stopper means on the outer surface of the vertical frame. The outer resin film is stretched, and a groove hole extending in the longitudinal direction is formed on the inner surface of the bone member. The resin film is sandwiched between the groove hole and the groove hole. A film holding plate to be held is attached, and an inner resin film is stretched to form a double-tensioned film structure.

  In other words, for the outer resin film stretched on the outer surface of the door, in consideration of being directly affected by wind and the like, while firmly stretching using a predetermined film fixing means provided exclusively, For the inner resin film stretched on the inner surface of the door, since the influence of wind or the like does not act directly, a slot hole extending in the longitudinal direction is formed on the inner surface of the bone member. The inner resin film is stretched with a comparatively simple structure in which a film pressing plate that holds and holds the resin film between the groove portions is attached.

  With this configuration, the door itself can be easily made into a film double tension structure. For example, if the roof noodle portion, side wall surface portion, wife surface portion, etc. of the vinyl house are film double tension, this implementation As in the embodiment, even the door can be easily made into a double film tension structure, and the entire house can be made into a film double tension structure, so that the heat retaining effect in the house can be further enhanced.

  For example, when a vinyl house with a film double tension structure other than the door is constructed, the film double tension structure of the entire vinyl house can be obtained at low cost by replacing only the door with the door according to this embodiment. realizable.

  In such a door for a vinyl house, the bone member on which the inner resin film is stretched can be used as a vertical frame constituting the frame body.

  That is, since the wind is not directly applied to the inner resin film, it is sufficient to fix it only to the vertical frame, and the structure of the door can be made simpler and the cost can be reduced. be able to.

  By the way, the film pressing plate is a cover in which a pair of leg pieces fitted into the slot and the base ends of the leg pieces are connected to each other and the distal ends are extended outward of the leg pieces. It is good to set it as the structure which formed the engaging part which engages with the convex edge which is formed in the side edge of the said slot part, and protrudes in the inner side of the said bone member in the said leg piece part. .

  That is, with the inner film covered on the inner side surface of the vertical frame made of a bone member, the film pressing plate having the above configuration is fitted into the groove hole by pushing the resin film into the groove hole from above the resin film. By engaging and locking, the inner resin film can be stretched inside the door very easily.

  In addition, a first extension end and a second extension end are formed on the left and right edges of the cover, respectively, with the tip extending outward, and the second extension end is higher than the center of the cover. While forming in a step shape, it is preferable to form longer than the said 1st extending end part.

  That is, when a pair of slidable left and right doors is configured, the vertical frames positioned inside the left and right doors are in contact with each other when the doors are closed. In this case, by setting it as the said structure, the 2nd extending end part of the film holding plate for doors attached to one vertical frame overlaps with the 1st extending end part of the film holding plate for doors attached to the other vertical frame. Can be. In this way, at the portion where one vertical frame and the other vertical frame meet each other, it is possible to prevent a gap from being generated when the door is closed by polymerizing the first extending end and the second extending portion. In addition, the airtightness in the vinyl house can be further improved.

  Further, the cover portion of the film pressing plate has a protruding thickness from the inner side surface of 0.5 to 2.0 mm in a state where the film pressing plate is fitted in a slot formed on the inner side surface of the bone member. It is preferable to be within the range.

  That is, by making the protrusion amount of the film pressing plate from the bone member surface as small as possible, even if the door is slid along the inner surface of the wife surface, the door frame and the film pressing plate are not in contact with each other. The door can be opened and closed smoothly. Further, it is possible to prevent the protruding portion from appearing on the inner surface of the vinyl house as much as possible, and the appearance is improved.

  In addition, it is desirable for the vinyl house to have a double-tensioned film structure on the wife face to which the door described above is attached. In this case, a double-faced film structure is realized with the same configuration as the door described above. it can.

  That is, an outer resin film is stretched on the outer surface of the bone member constituting the wife surface by a predetermined film stopping means, and a slot extending in the longitudinal direction is formed on the inner surface of the bone member. Since a film pressing plate that holds and holds the resin film between the groove hole portion is attached to the groove portion, the inner resin film is stretched, and the resin film is stretched on the front and rear surfaces of the bone member, respectively. is there.

  In this way, with a simple configuration, it is possible to realize a double-layered film structure of a vinyl house, increase the heat retention effect in the house, reduce the heating cost in winter, etc., and contribute to energy saving Can do. Moreover, since there is no protruding part inside the house, the appearance is good and the workability in the house is improved.
