(Viewpoints)
Japan has a long, narrow north-south country, and its topography is complex, such as inland, inland seas, islands, mountains, flat lands, basins, and sloping lands, and is surrounded by the sea. It has a unique climate and climate that is greatly different from each other, such as the Pacific High that strengthens the climate and the cold air masses that protrude from Siberia in the winter. In order to maintain agriculture, various forms of cultivation have been developed depending on the land, but a vinyl house as a simple facility that effectively uses solar energy is also an example of what was created for that purpose. I can say that.

    This vinyl house not only keeps the crop at a suitable temperature, but also protects the crop from the effects of wind and rain, and is advantageous for cultivating and managing crops during the cultivation period, such as irrigation, fertilization management, and pest management. There are many advantages over open-air cultivation, such as the ability to implement year-round cultivation, and it is a simple facility that requires relatively little economic burden and is easy to introduce. Because it is well adapted to Japan's agricultural situation in which it wants to stably produce good quality crops in a natural environment that does not have large farmland and changes its climate greatly throughout the four seasons, Widespread and used throughout the country as a variety of uses and sizes, including medium-sized ones for cultivating flowers and vegetables, and large ones for growing fruit trees such as cherry peaches. In You have me.

    Such widely used vinyl houses, especially medium-sized and large-sized vinyl houses, generally have a plurality of pipe frames arranged at predetermined intervals in the girder direction. This is a structure in which a plastic house such as vinyl chloride is stretched on the outer surface of a pipe house of the type, single roof type, double roof type, or double gradient type. While the sheet has been used for a single year or for several years, it is subject to repeated differences in wind and rain, sunlight, and temperature, and gradually deteriorates to reduce translucency, making it impossible to sufficiently capture sunlight. In addition to the inconvenience of losing elasticity, it can easily be broken by external forces such as strong winds, rain, hail, and snowfall. In order to prevent the occurrence of ripening due to overlapping with the maturity period, it is indispensable to attach vinyl sheets at high altitudes during the same season. There is an urgent problem that the facility must be protected from wind damage, etc., and it is always accompanied by work at a dangerous high place such as removing from the pipe house and re-stretching as necessary.

(Conventional technology)
However, the vinyl sheet tensioning work for this pipe house is distributed to the left and right from the highest point of the pipe frame, where the vinyl sheet must be seamless, large and long for that purpose, and is not so sturdy. Since it is necessary to make an attachment in the entire girder direction, the work is very large, and it is quite complicated and dangerous. In order to reduce such a burden as much as possible, the Kumamoto invention disclosed in, for example, Japanese Patent Application Laid-Open No. 7-289092, “House sheet stretching device” A sheet guide unit is movably provided along the movement guide unit disposed in the longitudinal direction of the house, and the leading end of the sheet is provided in the sheet guide unit. Is constructed so that the sheet can be stretched while being automatically moved along the roof surface, and the Hayakawa invention disclosed in JP-A-8-214710 “Roof sheet extending method and roof sheet in vinyl house” Auxiliary tool having a traveling part movable in the direction of the girder on the roof of the house skeleton shown in `` Auxiliary tool for extension '', and a seat mounting frame that is substantially orthogonal to the ridge along the arch shape of the roof, A sheet that is folded in a zigzag shape and is mounted on the sheet mounting base, and the sheet is stretched in a developed state while moving the traveling part in the direction of girder. Developments and proposals have been made on various techniques for setting up vinyl houses.

(Awareness of problems)
However, such conventional sheet laying equipment and roof sheet extending auxiliary tools, etc., are relatively large in size, and require a large amount of installation work for installation and a large amount of costs associated therewith. In addition, a lot of work must be spent on the removal work after the vinyl house is set up. In addition, it is impossible to stretch vinyl sheets with a large number of mica wires stretched across the entire skeleton body beam direction. When replacing vinyl sheets, all mica wires It is necessary to hang all the mica lines again after removing the cable once and stretching the vinyl sheet. In addition to spending a lot of time and effort, if a strong wind, wind, snow, etc. are blown in the stormy weather during that time, the sheet flutters and the work of passing the mica line becomes very difficult. It was not possible to easily reduce the burden of reworking.

(Object of invention)
In view of the above situation, the present invention eliminates a plurality of mica lines and eliminates any dangerous work at high places, and is efficient and simple. Judging whether it would be possible to quickly stretch vinyl sheets in a pipe house, we started developing and researching it quickly, and repeated trial and error over many years, and many trials and experiments.

(Related invention 1)
In relation to the vinyl sheet stretcher having the above-described configuration, this invention includes a method for stretching a vinyl sheet for a house using the vinyl sheet stretcher. The basic configuration is as follows. is there.
That is, a vinyl sheet bundle is appropriately attached to the outer surface of each sheet protection plate of a plurality of vinyl sheet stretchers arranged on the end side of a plurality of pipe frames perpendicular to the house traveling direction with appropriate intervals in the traveling direction. By tightening, hanging around the upper side of the pipe frame, towing the tow string that reaches the lower ground level near the lower end of the pipe frame from the end of the pipe frame on the opposite side or the neighborhood of the adjacent house frame , The left and right sliding cams of the vinyl sheet stretcher arranged at one end in either the direction of girder are made to enter the inside of the plurality of hanging mica wires and weight bars, and the sheet protection plate extends outside the pipe frame. It shall pass and slide across at least two adjacent frames of pipe frames arranged in parallel at predetermined intervals in the direction of the greenhouse. It is assumed that the girder frame is lifted so as to pass over one after another, and the track guide mechanism automatically contacts the upper peripheral surface of the girder frame to maintain the raised position during the lifting, and one end edge of the vinyl sheet bundle is stretched. Repeatedly pulling and manipulating other vinyl sheet stretchers arranged in a row in the order of the other vinyl sheet stretchers in order from the adjacent one, while being arranged in the pipe frame end side on the installation start side and gradually developing. In the process of pulling over the vicinity of the ridge to reach the end of the opposite pipe frame or near the valley with the adjacent house frame, the vinyl sheet bundle of each sheet protection plate is made of multiple mica wires and weights. After unfolding along the upper surface of the house frame, which is the lower side of the bar, temporarily tighten the mica wire by temporarily fixing the weight bar to the appropriate position on the pipe frame tension start end, and vinyl And gist configuration so as to stretched the over bets is Zhang 設方 method of vinyl sheet house with vinyl sheet Zhang 設器 according to the any one.

And temporarily fixed in the vicinity of the frame end is tensioned each mica lines, it can be said that Zhang 設方 method house for vinyl sheet so as to stretched vinyl sheet.

(Related invention 2)
Further, the present invention relates to a vinyl sheet stretcher constituting the backbone of the present invention and a method for stretching a vinyl sheet for a house using the same, and the present invention also includes a vinyl sheet end temporary attachment structure, The configuration is as follows.
In other words, at the center of the bottom of the rain gutter installed along the adjacent roof valley of the multi-storey type vinyl house, with an upright posture that is parallel to the girder direction and spaced at appropriate intervals in the girder direction A total of two connecting rods are arranged in parallel on both sides of a plurality of existing annular fittings, and each annular fitting has a substantially U-shaped cross section extending over the two connecting rods. The connecting rod, which is formed in the mold and is temporarily fixed, is attached to the center one side edge of the ring-shaped metal fitting, which is formed by engraving an engagement groove that can be engaged with the ring-shaped inner peripheral surface. Multiple mica wires that have one end connected to each of a plurality of suitable locations along the middle, each other end extending above the pipe frame building, and reaching the other location on the other end of the pipe frame, and other mica wires A vinyl sheet end composed of a structure in which a weight bar suspended and connected in a substantially horizontal shape is provided at the end. It is a temporary adhesion structure.

    More specifically, a connecting rod that is installed in parallel in the crossing direction at a suitable position on one end side of the pipe frame orthogonal to the crossing direction of the multi-walled vinyl house, and the connecting rod A plurality of mica wires that are connected at one end to a plurality of suitable locations in the middle, and each other end extends above the pipe frame and reaches the other end of the opposite pipe frame, and the other end of each mica wire. In addition, a weight bar connected in a suspended manner in a substantially horizontal shape is provided, and the weight bar goes over the end of the pipe frame formed in the shape of the eaves and is arranged so as to be parallel to the pipe frame in the direction of the vicinity. The end of the vinyl sheet is configured such that a plurality of fittings having a substantially C-shaped cross-section that are fitted from the outside and temporarily fixed to the pipe frame and the weight bar can be attached to the pipe frame and the weight bar. It can be said that it is a temporary attachment structure.

    As described above, according to the vinyl sheet stretcher of the present invention, the sharp ends of the left and right sliding cams raised by the tow string enter between the inside of the mica wire and the spindle and the outside of the pipe frame. When the bundle of vinyl sheets fastened to the outer surface of the sheet protection plate is raised in a state straddling at least two frames adjacent to each other in the direction of travel, the track guide mechanism or the track guide arm is engaged with the two frames. In addition to preventing the vehicle from deviating from the trajectory, if the hand is released from the tow strap during the ascending and the towing operation is stopped, the climbing position is secured on the pipe frame directly below to secure the ascending position. So, until now, the work of stretching vinyl sheets on house frames, where assistance from multiple workers or winches and towing by agricultural vehicles has been indispensable, Even if it is a human worker, the vinyl sheet bundle is raised to the vicinity of the pipe frame building reliably and comparatively easily by work on the ground, and further guided to the end of the pipe frame on the opposite side across the building to be safe and prompt. An excellent feature is that a vinyl sheet can be stretched.

    Further, according to the method for stretching a vinyl sheet for a house according to the present invention, a plurality of vinyl sheet stretchers are arranged along the traveling direction of the vinyl house, so that the vinyl sheet bundle is aligned in the traveling direction. Each pulling cord from the vinyl sheet stretcher on one end side in the crossing direction to the vinyl sheet stretcher on the opposite end side in the crossing direction. Each vinyl sheet stretcher after pulling the vinyl sheet to the opposite end of the pipe frame can be stretched in a stretched manner by pulling the vinyl sheet sequentially. Tighten each mica wire while it is placed between the pipe frame and the vinyl sheet, or temporarily remove it from between the pipe frames and tighten the mica wire to stretch the vinyl sheet In addition, when the vinyl sheet has deteriorated due to long-term use, the vinyl sheet is dragged down, and each vinyl sheet stretcher is pulled and moved to the pipe frame tension start end side again. Alternatively, it can be reattached to the pipe frame tension start end to enable the vinyl sheet tensioning work, even to a single worker, to the extent that was impossible before. In addition to being able to quickly carry out the vinyl sheet tensioning work, it is possible to significantly improve safety by eliminating the need to work on high places on a ladder or pipe frame.

    Furthermore, according to the vinyl sheet end temporary attachment structure of the present invention, the two connecting rods can be temporarily fixed on the rain gutter installed along the roof valley portion of the continuous vinyl house. Therefore, compared to the case where only one connecting rod is provided, the durability strength when multiple mica wires are connected can be increased by a factor of about 2, and the vinyl sheet can be tightened more securely. Even when hit by stormy weather such as strong winds and heavy snow, it will be possible to obtain higher strength. As a result of overcoming both ends of the pipe frame and parallel to the girder frame in the vicinity thereof, it is possible to attach a plurality of fittings that fit across both the weight bar and the pipe frame, Easy and efficient temporary attachment of vinyl sheets Ukoto will be able to, it becomes to achieve the remarkable effect that it is possible to further improve the work efficiency.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The slide-through cam is lifted by connecting the left and right ends of the sheet protection plate or the left and right ends of the horizontal bar to the bifurcated ends of the tow string, and allows for towing operation. The pipe structure of the vinyl house is on the lower side, the mica wire and the weight bar connected to it are automatically selected on the upper side, and the width is gradually increased so that the seat has a generally wedge-shaped side shape. The protective plate (horizontal bar) has a complex function that can guide the pipe frame end protruding in the shape of the eaves to automatically get over, and between the left and right sliding cams, Since it can be arranged across at least two adjacent frames orthogonal to the direction and constitute a part of the trajectory guide mechanism, it is assumed that it is formed in the shape of a vertical plate type piece. However, it is also possible to make a three-dimensional object other than that including a substantially wedge-shaped side cross-sectional shape, and a hard resin plate or metal plate for reinforcing or reducing friction is pasted on the outer peripheral surface in contact with the pipe frame. It can be worn.

    The tow string is a vinyl house pipe that is pulled by the manual pulling operation of the vinyl sheet stretcher body including the left and right sliding cams, the sheet protection plate (horizontal bar), and the track guide mechanism from the ground inside and outside the vinyl house. It pulls in the direction perpendicular to the girder direction on the upper side of the frame and functions to move in a transverse manner, enough to pull the main body part of the vinyl sheet stretcher with a bundle of vinyl sheets The material should be strong enough and should not be inadvertently damaged by contact, and should be selected at one end of the direction perpendicular to the direction of the plastic house pipe frame. One end side is connected to the vinyl sheet stretcher, and the other end side is hung from the other end of the vinyl house by hanging around the upper side of the pipe frame. In addition, the end of the vinyl house pipe frame is endless in a direction perpendicular to the carry direction of the vinyl house pipe frame. It can be connected to each sharp end of the drop cam.

    The sheet protection plate is formed by tying a bundle of vinyl sheets on the outer surface of the sheet protection plate, straddling at least two adjacent pipe frames perpendicular to the direction of the vinyl house girder, and sliding and moving along these pipe frames. When the bundle is unfolded and the vinyl sheet can be stretched on the upper side of the pipe frame, it has sufficient strength that it does not easily deform even when the vinyl sheet bundle is mounted, or it is easy to deform For example, by providing a horizontal bar as necessary, the width of the pipe frame perpendicular to the direction of the direction of the vinyl house is slightly larger than the distance between two adjacent frames, and a bundle of vinyl sheets is attached. It should be formed in the shape of a substantially rectangular flat plate set to a vertical dimension as much as possible, and is limited to a weight that can ensure relatively light traction operability. It is desirable to things such as synthetic resin plate or plywood, had better be a wooden board made like.

    The trajectory guide mechanism prevents the vinyl sheet stretcher from deviating from at least two adjacent frames orthogonal to the direction of travel in the process of rising along the vinyl house pipe frame. When the traction input to the traction string is stopped, the track is automatically engaged with the outer peripheral wall surface that forms the horizontal direction of the pipe frames arranged in the direction of the pipe frame. In combination, it serves as a function that prevents the dropout and ensures the position of the vinyl sheet stretcher to be pulled up. When raising the vinyl sheet stretcher, When it interferes with a plurality of pipe frames installed, it must be structured so as to be retracted in a swinging manner and automatically disengaged. For example, it is swingably suspended on the left and right ends of a horizontal bar. Outlined A trajectory guide arm composed of a frame-shaped member having a letter shape or a substantially triangular shape, and a hook-shaped member that performs the same function is integrally formed at the lower end of the slide-through cam or the lower end of the sheet protection plate Is possible.

    The horizontal bar suspends and connects the sheet protection plate so as to be able to follow the left and right sliding cams, and secures and maintains the distance set between the sliding cams and the width of the sheet protection plate. It should fulfill the function and should be formed from a rod-like body that has sufficient strength to suspend and lift up the sheet protection plate with the vinyl sheet bundle bound along the pipe frame of the vinyl house. It is either integrated with the longitudinal edge of the sheet protection plate, or the concentric shaft for connecting the sliding cam and the locking leg from the left and right ends of the longitudinal edge of the sheet protection plate. The length of the pipe frame should extend over at least two adjacent pipe frames perpendicular to the direction of the greenhouse.

    The vinyl tensioning method for house is based on the same work process, regardless of the type of vinyl house, such as round roof type or double roof type, or single-building type or multi-building type. For example, even if it is a dome-shaped vinyl house suitable for cultivation of vegetables, flowers, etc., it is also used for tall vinyl houses installed for fruit trees such as cherry peaches, persimmons, and flowerless fruits. It can be suitably implemented regardless of whether it is a new house or an existing house, and a plurality of vinyl sheet stretchers are arranged along the direction of travel, and one or a small number of workers can make vinyl sheets. Each vinyl sheet stretcher can be safely and easily deployed and stretched by appropriately pulling each vinyl sheet stretcher. The procedure is appropriate each time. It is possible to carry out the vinyl sheet unfolding work in the direction of the girder, and it is sufficient to advance it in a substantially uniform degree and to perform a pulling operation so that an unnecessary burden is not applied to the vinyl sheet. However, it is not necessary to strictly limit the pulling order of each vinyl sheet stretcher, but from the vinyl sheet stretcher disposed on either end side of the carry direction, the vinyl sheet stretcher adjacent to the opposite end side It can be said that it is preferable to sequentially apply a pulling operation to the fixture. In addition, the number of workers involved in the stretching work is not particularly limited, and even one person can proceed quickly and safely, and if the number of workers increases, Thus, the tensioning work can be completed in a short time.

    The mica wire is used to hold the vinyl sheet, etc., developed on the upper side of the vinyl house pipe frame so that wrinkles and slack do not occur. In the case of a round roof type, one end of the pipe is perpendicular to the direction of the girder. Connect to the appropriate place on one end of the frame, near the edge of the eaves-shaped pipe frame in the case of the roof type, or near the rain gutter installed in the valley in the case of the continuous type, The other end is hung in the direction perpendicular to the direction and hung on the opposite end of the pipe frame, and a horizontal weight bar can be attached to the other end. It must be made of a material and a shape that has sufficient strength and does not inadvertently damage the vinyl sheet.

    The connecting rod can be temporarily fixed at one end of a plurality of pipe frames perpendicular to the direction of the direction of the vinyl house, or adjacent to the multi-walled vinyl house. It functions to make it possible to temporarily fix it on the bottom of the rain gutter along the girder direction that is installed in the valley with the roof, and it must be strong enough to withstand the tensile input from each mica wire. In addition, it can be assumed that one ring is inserted from the girder direction and temporarily fixed to the ring brackets erected at a plurality of locations along the girder direction on the bottom of the gutter. In an upright posture that is parallel to the beam direction, a total of two rings are arranged in parallel on each side of a plurality of ring brackets that are scattered at appropriate intervals in the beam direction. Each is formed into a bowl shape with a substantially U-shaped cross section straddling two connecting rods. It can be its center one side edge fitted with a hook bracket comprising as having been engraved engaging groove to be engageable with the ring-shaped inner peripheral surface of the annular fitting, and that the temporarily fixed shape.

    Annular metal fittings serve to temporarily fix multiple locations of connecting rods that are parallel to the direction of the vinyl house girder at appropriate locations on the bottom of the rain gutter. It must have a ring-shaped opening and must be firmly fixed to the rain gutter, and be arranged in a dotted manner along the girder direction so as not to overlap with the location of the mica line. It is desirable that the ring-shaped opening is directed in a direction substantially perpendicular to the direction of the greenhouse and the connecting rods can be mounted in parallel on the left and right sides one by one.

    The metal fittings are easily attached to and removed from the annular fitting, and straddle and engage with both of the two connecting rods arranged in parallel on both sides of the annular fitting. It should function to be temporarily fixed to the bottom of the gutter in each direction, should be removable without the need for tools, and is formed into a generally U-shaped saddle shape with its central one side edge It is desirable that an engagement groove that can be engaged with the ring-shaped inner peripheral surface of the ring-shaped metal fitting is engraved.

    The weight bar shall be temporarily fixed in place on the pipe frame end side on the opposite side of the connecting rod from the other end of the plurality of mica wires with one end connected to the connecting rod. In order to achieve the function of attaching a vinyl sheet to the upper surface of the pipe frame, it must have the strength to withstand the tensile input from each mica wire as well as the connecting rod. It should be able to secure the weight that can be tensioned in a hanging shape across the girder in a nearly uniform manner, and in the case of a roof type vinyl house, get over the edge of the eaves-like pipe frame and its vicinity Fitting with a substantially cross-sectional C-shape that is fitted into the pipe frame and the weight bar from the outside to be temporarily fixed when arranged so as to be parallel to the pipe frame in the longitudinal direction Do not allow multiple brackets to be attached. It can be a thing.

    When the weight bar becomes parallel to the pipe frame in the direction of the girder, the fitting is used to connect a plurality of appropriate positions of the weight bar and the girder frame in a temporarily fixed state. Yes, it must be detachable relatively easily without the use of tools, and it is fitted from the outside to the weight bar and girder frame with the vinyl sheet edge sandwiched between them. Thus, it is desirable to use a part having a substantially C-shaped cross section that can be temporarily fixed, and can be formed by appropriately molding a metal plate or a metal rod excellent in springiness.

The house frame serves the function of forming a skeletal part that can form agricultural cultivation facilities, simple warehouses, and garages, and has a single roof type, a single roof type, a single roof type, a three quarter type, both It consists of a pipe frame assembled in any structure including typical types such as roof type, double roof type, double gradient type, and high roof type for fruit trees, and the area corresponding to the outside, especially the roof As long as the vinyl sheet can be attached to the upper side of the roof, in the case of a continuous building type, rain gutters are attached along the valleys formed between adjacent roofs, and adjacent in the direction of girder A mica wire perpendicular to the direction of the carry is routed between each pipe frame, one end is connected to one pipe frame end side, and the other end extended to the pipe frame end side opposite to this is connected , Pipe fluff in the direction of girder It is desirable to those respectively bound to beam position to the corresponding position of the temporary fixable to the weight bar.
In the following, the structure of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.
