Description

  The present invention relates to a film stopper member used for fixing a film in a greenhouse structure in which a film is stretched on a skeleton, and a dew collection structure including the same, and more particularly, has a portion for receiving dew and rainwater. The present invention relates to a film stopper member and a dew recovery structure including the same.

  The greenhouse structure (called a vinyl house, etc.) that constitutes a greenhouse for growing vegetables, fruits, etc., is a structure in which a transparent film made of synthetic resin or the like is stretched over a framework in which skeleton materials are assembled. Is provided. The frame material constituting the framework of the greenhouse structure includes, for example, arch pipes that are a plurality of arch-shaped pipe members arranged at appropriate intervals in the longitudinal direction of the greenhouse structure, and in the connecting direction of these arch pipes. And a linear (rail-shaped) film stopper member which is installed in a substantially horizontal direction along the surface and used for fixing the film.

  In such a greenhouse structure, a large amount of dew is formed on the inner surface of the film due to temperature differences inside and outside the greenhouse, physiological effects of plants cultivated in the greenhouse, evaporation of water sprinkled in the greenhouse, etc. Occurs. In a greenhouse structure, rainwater may enter the greenhouse from a broken film. The dew generated on the inner surface of this film and the rainwater that enters the greenhouse can fall into the greenhouse, causing plant root rot and disease, adversely affecting plant growth, and working in the greenhouse. Make people uncomfortable.

  Thus, conventionally, various techniques for collecting dew and rainwater in a greenhouse structure have been proposed. For example, Patent Document 1 discloses a dew recovery device that includes a film stopper member that is connected to each other in the longitudinal direction and a joint member that connects these members to each other. In such a dew recovery device, a dew receiving portion for receiving dew and rainwater is provided in the film stopper member, and a predetermined water guide path and a drain nozzle for guiding dew etc. are provided in the joint member. And, for example, dew generated by dew condensation on the inner surface of the film flows into the joint member from the dew receiving portion of the film stopper member and is collected, and the joint member has a predetermined hose connected to the drain nozzle through a predetermined water conduit. Discharged to the place.

  The film stopper member having a conventional dew receiving portion as disclosed in Patent Document 1 specifically has the following structure. That is, as shown in FIG. 25 (a), the conventional film stopper member 110 is a linear long member, and has a substantially trapezoidal film stopper groove 120 with the upper bottom side open as a cross-sectional shape. And a dew receiving portion 130 provided on one side of the film stopping groove 120.

  The film stopping groove 120 includes a bottom plate portion 121 and side wall portions 122 that are bent at both ends of the bottom plate portion 121 as a substantially trapezoidal portion having a transverse cross section. In the film stopping groove 120, a film mounting groove which is a substantially trapezoidal groove-like space in a cross section to which the transparent film 102 is fixed is formed by the bottom plate part 121 and the side wall part 122.

  The dew receiving portion 130 includes a connecting portion 140 that extends substantially in parallel with the bottom plate portion 121 from the front end portion of the side wall portion 122 on one side (left side in FIG. 25A) of the film stopping groove portion 120 in the cross-sectional shape. Is provided. The dew receiving part 130 is opposite to the film stopping groove 120 side from the first wall part 131 formed along the groove depth direction of the film stopping groove part 120 from the connecting part 140 and the lower end part of the first wall part 131. The second wall portion 132 is formed on the side (left side in FIG. 25A) along the plate surface direction of the bottom plate portion 121, and is substantially L-shaped in cross-sectional shape.

  In such a film stopper member 110, as shown in FIG. 25 (b), the film 102 is generally sandwiched between the bottom plate portion 121 and the spring 108 by a wavy line spring 108. Fixed. That is, the spring 108 has a wavy linear amplitude direction along the substantially flat bottom plate portion 121 with respect to the film stopper member 110 and is fitted to the corner portions on both sides of the bottom plate portion 121 and the side wall portion 122. It is installed in the state.

  Further, the film stopper member 110, as shown in FIG. 25 (b), functions so that the portion of the dew receiving portion 130 functions as a bowl-shaped portion that receives dew and rainwater and guides it in a predetermined direction while retaining water. For example, along the inclination of the arch pipe 103 constituting the framework of the greenhouse structure, the width direction is inclined with respect to the horizontal plane (see the straight line X1) so that the dew receiving portion 130 is on the upper side. That is, the film stopper member 110 has a substantially L-shaped corner portion positioned on the lower side in the cross-sectional shape as described above, that is, the substantially L-shaped dew receiving portion 130 is approximately V with respect to the horizontal plane. It is provided in an inclined state so as to form a letter. As a result, the dew 180 generated on the inner surface of the film 102 at the corner portion of the dew receiving unit 130 flows into the dew receiving unit 130 along the inner surface of the film 102 and is collected. In addition, in FIG.25 (b), illustration of the coupling member which comprises a dew collection | recovery apparatus with the film stop member 110 is abbreviate | omitted.

  Certainly, according to the film stopper member having a structure as disclosed in Patent Document 1, it is possible to collect dew generated on the inner surface of the film, rainwater entering from a broken part of the film, and the like. However, in the film stopper member having the conventional dew receiving portion as described above, it is desired to improve the following problems.

  First, according to the conventional film stopper member, in order for the dew receiving part to function as a bowl-shaped part, the dew receiving part having a substantially L-shaped cross section is substantially V-shaped with respect to the horizontal plane. Thus, it is necessary to provide the film stopper member in a state inclined with respect to the horizontal plane (see FIG. 25B). Therefore, when the film stopper is provided at the top of the arch pipe or in the vicinity of the arch pipe in the direction of the arch shape, the film stopper may be in a state in which the width direction is substantially horizontal or close thereto. Therefore, the function of retaining dew and rainwater is not sufficiently obtained in the dew receiving part, and it becomes difficult to make the dew receiving part function as a bowl-shaped part. In other words, the conventional film stopper member has a limited versatility in order to sufficiently function the dew receiving portion, and is poor in versatility.

  In addition, the film stopper member is fixed to a plurality of arch pipes at a crossing portion by a predetermined holding structure. However, according to the conventional film stopper member, the holding structure is caused by the shape of the film stopper groove or the like. Is limited to one type. For this reason, the structure for fixing cannot be changed according to the position or shape of the fixing portion of the film fixing member with respect to the arch pipe, and it can be said that the conventional film fixing member is poor in versatility also in this respect. .

  Also, in relation to the holding structure caused by the shape of the film stopper member, according to the conventional film stopper member, a spring that is mounted in the depth direction of the groove of the film stopper groove to fix the film The number is limited to about three at the maximum because of the structure. In this regard, depending on the location of the greenhouse structure, for example, there is a portion where a number of films such as a wife's surface film, a roof surface film, a windproof / insect-proof film, and the like overlap. There is a demand for a structure in which four or more springs can be mounted in the film stopper groove of the film stopper.

  Furthermore, since the conventional film fixing member has a structure that is folded in the width direction without particularly overlapping portions of plate-like members, the film fixing member has sufficient strength as a skeleton material constituting the framework of the greenhouse structure. It is difficult. If sufficient strength is not obtained in the film stopper member, deformation in the longitudinal direction of the film stopper member is likely to occur, or the film stopper member may be bent due to strong wind or the like in some cases. In order to solve such a problem due to insufficient strength of the film stopper member, it is conceivable to shorten the length of the single film stopper member and shorten the arrangement pitch of the connecting portions of the plurality of film stopper members. However, shortening the arrangement pitch of the connecting portions of the plurality of film stopper members increases the number of parts in terms of the framework structure of the greenhouse structure, increasing the labor for manufacturing the greenhouse structure and increasing the cost. It becomes.

The present invention has been made in view of the above problems, and in a structure having a portion for receiving dew and rainwater, the versatility and strength can be improved, and the number of springs that can be attached is easy. and to provide a dew collection structure with a film stopper member can be increased to.

The dew recovery structure according to the present invention comprises a greenhouse structure having a structure in which a film is stretched on a framework, and is connected to a linear film stopper member for fixing the film and a linear film stopper member in the longitudinal direction. A dew collecting structure comprising a joint member for connecting the two film stopper members to each other , wherein the film stopper member includes a substantially flat bottom plate portion and an intermediate portion in the width direction of the bottom plate portion. A pair of side wall portions that are provided so as to rise from one plate surface side of the bottom plate portion and face each other in the width direction and form a film fixing groove for fixing the film together with the bottom plate portion, and the bottom plate portion provided so as to rise from both end portions in the width direction, e Bei and a edge walls forming a water receiving groove for receiving the water together with the bottom plate portion and the side wall portion, the coupling member from the water receiving groove A water flow path for receiving water Komu are those having, front and rear of the nozzle communicating with the water flow path is provided on both sides on the opposite sides of the joint member.
Further, in the film stopper member according to one aspect of the present invention, the water flow path has water receiving groove portions formed in steps up and down, and the front and rear nozzles have one nozzle connected to the water receiving groove portion. The upper nozzle is communicated with the other nozzle, and the other nozzle is communicated with the lower part of the water receiving groove.

Further, in the dew collection structure according to one aspect of the present invention, the side wall portion is inclined so as to approach a vertical portion that rises substantially vertically from the bottom plate portion, and toward the opposite side wall portion side from the vertical portion. An inclined portion, and a protruding portion provided on the leading end side of the inclined portion and protruding inside the film fixing groove.

Moreover, in the dew collection | recovery structure which concerns on 1 aspect of this invention, the said film fixing groove is provided in the position which shifted the center position of the said width direction from the center position of the said width direction of the said baseplate part.

Moreover, the side wall part 13 has the outer wall surface 13e which forms the water-receiving groove | channel 14 in the outer side (opposite side wall side 13 side of the other party which opposes). And the inner wall surface 15a of the edge wall part 15 and the outer wall surface 13e of the side wall part 13 form the substantially rectangular cross-sectional shape by which the upper side was open | released with the edge part upper surface 11b which is the upper surface of the bottom-plate edge part 11y, A portion having a substantially rectangular shape with the upper side opened is a portion that functions as the water receiving groove 14.

  The film stopper member 10 according to the present embodiment having the above-described configuration is configured symmetrically with respect to a predetermined center position in the width direction. In the following description, in the film stopper member 10 having a symmetrical shape in the width direction, the center position side is defined as the inner side and the edge end side is defined as the outer side in the width direction.

  The film stopper member 10 of this embodiment will be described in more detail with reference to FIG. The film stopper member 10 of this embodiment is configured by bending a flat plate member having a predetermined plate thickness (for example, about 1 mm). That is, in the film stopper member 10, the film fixing groove 12 and the water receiving groove as described above are formed by bending in the width direction (short direction) with respect to a long rectangular plate-like member (band plate-like member). Each part forming 14 is provided. Therefore, the cross-sectional shape of the film stopper member 10 is composed of a continuous straight portion and a curved portion having a width corresponding to the plate thickness.

  The side wall portion 13 that forms the film fixing groove 12 is formed in a mode in which the plate-like member is erected from the planar bottom plate portion 11 in a substantially vertical direction. Therefore, the side wall portion 13 has an upper and lower side connecting the outer end portion of the bottom plate intermediate portion 11x forming the film fixing groove 12 and the inner end portion of the bottom plate end portion 11y forming the water receiving groove 14 in the cross-sectional shape.

This is a portion having a cross-sectional shape. The inclined portion 13c is an inclined portion that is inclined upward and inward from the upper end of the vertical portion 13b, and constitutes an upper portion of the inner wall portion 13x of the side wall portion 13. The protruding portion 13d is provided on the leading end side of the inclined portion 13c and protrudes inside the film fixing groove 12 and forms an opening end on the upper side of the film fixing groove 12. Due to the protruding portion 13d, the dimension in the width direction of the film fixing groove 12 becomes discontinuously narrow with respect to the same dimension at the position of the inclined portion 13c.

  On the other hand, the outer side wall part 13y which forms the water receiving groove 14 among the side wall parts 13 is a part which stands | starts up substantially perpendicularly from the baseplate part 11, and consists of a linear part along a vertical direction mainly in cross-sectional shape. That is, the outer wall portion 13y is a portion that rises in a substantially vertical direction from the inner end portion of the bottom plate end portion 11y of the bottom plate portion 11, and is a portion that forms a substantially L-shaped cross-sectional shape together with the bottom plate end portion 11y.

  The outer wall portion 13y is provided in a state in which the lower portion thereof is in contact with the vertical portion 13b constituting the lower portion of the inner wall portion 13x from the outside. That is, the vertical part 13b of the inner wall part 13x and the lower part of the outer wall part 13y, both of which are parts substantially perpendicular to the bottom plate part 11, are provided so as to overlap each other in the width direction. Therefore, in the side wall part 13, the inclined part 13c which inclines inward from the upper end of the vertical part 13b, the upper part of the outer wall part 13y which is a part substantially perpendicular to the bottom plate part 11, and these parts. With the curved portion 13z that connects the upper end portions of each other, a substantially right-angled isosceles triangular cavity is formed with the upper and outer sides at the right-angle portion side in the cross-sectional shape (see FIG. 3). In the bottom plate portion 11, the bottom plate intermediate portion 11 x that forms the film fixing groove 12 and the bottom plate end portion 11 y that forms the water receiving groove 14 are substantially flush with the lower surface of the bottom plate portion 11. , Constituting a substantially continuous flat plate-like portion.

  The edge wall portion 15 that forms the water receiving groove 14 is a portion that is bent substantially perpendicularly to the bottom plate end portion 11y from the outer end portion of the bottom plate end portion 11y, and has a folding portion 15c at the upper end portion thereof. . The folding portion 15c is a portion formed by folding the tip end portion (upper end portion) of the edge wall portion 15 inward so as to form a substantially cylindrical space.

  The film stopper member 10 having the above configuration basically has a constant cross-sectional shape regardless of the position in the longitudinal direction. Therefore, the cross-sectional shape of the film stopper member 10 and the shape of the end face in the longitudinal direction are the same shape. The film stopper member 10 includes a bottom plate intermediate portion 11x of the bottom plate portion 11 and left and right ends of the bottom plate intermediate portion 11x as portions that form a substantially trapezoidal film fixing groove 12 whose upper side is open in the cross section. A vertical portion 13b, an inclined portion 13c, and a protruding portion 13d, which are sequentially located from the top to the top. A space between the projecting portions 13 d facing each other is a portion opened in the film fixing groove 12.

  A wavy linear spring 8 is used for the film fixing groove 12, and the film 2 is fixed (see FIG. 2). Specifically, the spring 8 has a wavy linear amplitude direction along the substantially flat bottom plate intermediate portion 11x with respect to the film fixing groove 12, and includes a bottom plate intermediate portion 11x and an inner wall portion 13x. It is mounted in a state where it is fitted to the left and right corners. The film fixing groove 12 receives the mounting of the spring 8 while being covered with the film 2 from the protruding portion 13d side. For this reason, the film 2 is fixed in a state of being sandwiched between the bottom plate intermediate portion 11 x and the spring 8. The film 2 is pressed against the left and right corners of the bottom plate intermediate portion 11x by the spring 8 and clamped to the film stopper 10 in a manner along the inner surface of the film fixing groove 12. In the greenhouse structure 1 where a plurality of films overlap, etc., a plurality of springs 8 are appropriately used in the film fixing groove 12 of one film stopper 10. In this case, the plurality of springs 8 are used so as to overlap in the vertical direction in the film fixing groove 12.

  In the film stopper member 10 having the above configuration, the film fixing groove 12 is formed by the bottom plate middle portion 11x of the bottom plate portion 11 and the inner wall portions 13x of the pair of side wall portions 13 facing each other. A groove is formed. And on both the left and right sides of the film stopping groove, a dew receiving portion that forms the water receiving groove 14 is formed by the bottom plate end portion 11y of the bottom plate portion 11, the outer wall portion 13y of the side wall portion 13, and the edge wall portion 15. Composed. Thus, in the film stopper member 10 of the present embodiment, the side wall portion 13 erected from the bottom plate portion 11 includes the inner side wall portion 13x and the outer side wall portion 13y, so that the film fixing groove in the side wall portion 13 is obtained. The part forming 12 and the part forming the water receiving groove 14 are independent from each other.

The groove depth increases in the order of the receiving groove 28, the middle water receiving groove 26, and the lower water receiving groove 27. In particular, the portion communicating with the lower nozzle 32 of the lower water receiving groove 27 is formed deepest.

  In the joint 20 having the above-described configuration, at least one of the upper nozzle 31 and the lower nozzle 32 is used as a discharge-side nozzle. For example, when the joint 20 is provided in a posture in which the front-rear direction is inclined with respect to the horizontal plane (see, for example, FIG. 2), the lower nozzle 32 of the upper nozzle 31 and the lower nozzle 32 is used as the discharge side nozzle. In this case, the joint 20 is provided in an inclined state so that the lower nozzle 32 side communicating with the lower part of the lower water receiving groove 27 having the deepest groove depth is on the lower side. A discharge hose 9 </ b> A for discharging the collected dew and rainwater from the joint 20 is connected. This prevents water from remaining in the water flow path of the joint 20, particularly in the lower water receiving groove 27. In this regard, if the joint 20 is provided in an inclined state so that the upper nozzle 31 is on the lower side, the upper stage portion continuous with the upper nozzle 31 and the lower stage portion continuous with the lower nozzle 32 in the lower water receiving groove portion 27.

  Further, when the joint 20 is provided in an inclined state with the lower nozzle 32 side as the lower side, the upper nozzle 31 on the opposite side of the lower nozzle 32 side is used for inflow with the inflow hose 9B connected thereto, In particular, it is used as an open part that opens one side in the front-rear direction of the water flow path of the joint 20 without receiving connection of a hose or the like. When the inflow hose 9 </ b> B is connected to the upper nozzle 31, the hose 9 </ b> B is, for example, a discharge hose 9 </ b> A connected to the lower nozzle 32 of another joint 20 provided at a position higher than the joint 20. It is equivalent to.

  The example of the usage condition of the dew collection | recovery structure 40 of this embodiment provided with the film stop member 10 and the joint 20 as mentioned above is demonstrated using FIGS. As shown in FIG. 10, in the greenhouse structure 1, the dew collection structure 40 is provided in a state where the film stopper member 10 side is located outside, and is connected to the film stopper member 10 connected by the joint 20. The film 2 is fixed and stretched by a spring 8 (see FIG. 2). That is, the film stopper member 10 is installed outside the arch pipe 3 in a state of being connected in the longitudinal direction of the greenhouse structure 1, and is located on the inner side with respect to the film stopper member 10 at the connecting portion between the film stopper members 10. Connected by the joint 20.

  As shown in FIG. 10, the connection structure of the film stopper member 10 by the joint 20, that is, the dew collection structure 40, extends from the roof top side (upper end side) to the side side of the greenhouse structure 1 along the curvature of the arch pipe 3. , Provided on the slope part (part indicated by reference sign D) which is the middle part of the roof, or on the top part of the roof (part indicated by reference sign E).

  The dew collection structure 40 located on the slope portion of the roof of the greenhouse structure 1 (see symbol D, hereinafter referred to as “roof slope portion”) is orthogonal to the longitudinal direction of the film stopper 10 corresponding to the inclination of the arch pipe 3. It is provided in a manner in which the front-rear direction of the joint 20 is inclined. Here, the joint 20 is inclined in the direction in which the lower nozzle 32 is on the lower side as described above. On the other hand, the dew collection structure 40 located on the top of the roof of the greenhouse structure 1 (see symbol E, hereinafter referred to as “roof top”) is provided in a mode in which the front-rear direction of the joint 20 is substantially horizontal. . In the example shown in FIG. 10, the joint 20 located at the top has the lower nozzle 32 directed to the side where the corresponding dew collection structure 40 exists on the slope of the roof (the right side in FIG. 10).

  One end of the discharge hose 9 is connected to the lower nozzle 32 of the joint 20 located on the roof slope portion. The other end of the hose 9 is arranged toward a trough 18 provided in a trough between adjacent greenhouse structures 1 in a so-called multi-storied house in which two or more greenhouse structures 1 are arranged side by side. The dew and rainwater collected by 20 are discharged to the trough 18 by the hose 9. The trough 18 has a substantially V shape or a substantially U shape as a whole, for example, when a linear long plate-like member made of a metal material such as stainless steel or aluminum alloy is appropriately bent in the short direction. It is a member formed in a concave shape.

  On the other hand, one end of the inflow hose 9 is connected to the upper nozzle 31 of the joint 20 located on the roof slope portion. The other end of the hose 9 is connected to the lower nozzle 32 of the joint 20 located on the roof top. In the example shown in FIG. 10, the upper nozzle 31 of the joint 20 located at the roof top is open without receiving a hose connection. In this way, the hose 9 arranged from the joint 20 of the dew collection structure 40 toward the trough 18 and the hose 9 connecting the joint 20 located on the roof top and the joint 20 located on the roof slope portion are, for example, an arch It is provided in a state where it is fixed and supported at an appropriate position on a member constituting the framework of the greenhouse 1 such as the pipe 3.

  Dew and rainwater collecting actions in the dew collection structure 40 provided on the roof slope portion and the dew collection structure 40 provided on the roof top as described above will be described.

  First, the dew collection structure 40 provided on the roof slope portion will be described with reference to FIG. As shown in FIG. 11, in the dew collection structure 40 provided on the roof slope portion, the film stopper member 10 is held by the joint 20 whose front and rear direction is inclined along the inclination of the arch pipe 3 as described above. The width direction (left and right direction in FIG. 3) is inclined with respect to the horizontal plane (see the straight line X1). The film stopper member 10 in this state is inclined in the width direction, the water receiving groove 14 on one side in the width direction is positioned on the upper side, and the bottom plate end portion 11y and the outer wall portion 13y forming the upper water receiving groove 14 are formed. The substantially L-shaped cross-sectional shape consisting of is inclined so as to be substantially V-shaped with respect to the horizontal plane (see the straight line X1). Further, in the water receiving groove 14 on the upper side of the inclined film stopper member 10, an edge wall portion 15 facing the outer wall portion 13 y exists on the upper end side of the bottom plate end portion 11 y. Therefore, in the upper water receiving groove 14, in addition to the bottom plate end portion 11y and the outer wall portion 13y that are substantially V-shaped with respect to the horizontal plane in the cross-sectional shape, the outer wall portion 13y extends from the upper end portion of the bottom plate end portion 11y. The edge wall portion 15 that rises in parallel to the outer wall 13y and faces the outer wall portion 13y forms a substantially U-shaped or substantially J-shaped groove that is surrounded by approximately three sides in a cross-sectional shape. This groove functions as a bowl-shaped portion that receives dew or rain water and guides it in a predetermined direction while holding the water.

  Similarly, the film stopper member 10 in the inclined state has the water receiving groove 14 on the other side in the width direction positioned below, and the bottom plate end portion 11y and the edge wall portion 15 that form the water receiving groove 14 on the lower side. The substantially L-shaped cross-sectional shape consisting of is inclined so as to be substantially V-shaped with respect to the horizontal plane (see the straight line X1). In addition, in the water receiving groove 14 on the lower side of the film stopper member 10 in the inclined state, an outer wall portion 13y that faces the edge wall portion 15 exists on the upper end side of the bottom plate end portion 11y. Accordingly, in the lower water receiving groove 14, in addition to the bottom plate end portion 11 y and the edge wall portion 15 that are substantially V-shaped with respect to the horizontal plane in the cross-sectional shape, the edge wall portion extends from the upper end portion of the bottom plate end portion 11 y. As a result of the presence of the outer wall portion 13y parallel to the rising edge wall 15 and facing the rising edge wall portion 15, a substantially U-shaped or substantially J-shaped groove surrounded by approximately three sides in the cross-sectional shape is formed. This groove functions as a bowl-shaped portion that receives dew or rain water and guides it in a predetermined direction while holding the water.

  In the roof slope dew collection structure 40 as described above, as shown in FIG. 11, the dew 80 generated on the inner surface of the film 2 and rainwater entering the greenhouse are fixed on the film stopper 10. The film descends along the inner surface, reaches the film stopper 10 and travels along the side wall portion 13 or directly drops from the film 2 to flow into the upper and lower water receiving grooves 14 and be collected.

  Specifically, regarding the dew generated on the inner surface of the film 2, the dew 80 generated on the inner surface of the film 2 above the upper side wall portion 13 reaches the film stopper member 10 and travels through the side wall portion 13. By being dropped directly from 2, it is mainly collected by the upper water receiving groove 14 (see arrow Y <b> 1).

  As for rainwater that enters the greenhouse, the rainwater enters the greenhouse from the torn portion of the film 2. In the film 2 fixed to the joint 20, tearing tends to occur at a contact portion with respect to the tip portion of the side wall portion 13. Therefore, rainwater entering from the tearing of the film 2 generated in the vicinity of the tip of the lower side wall part 13 is transmitted directly through the outer wall part 13y of the lower side wall part 13 or dropped directly from the film 2. It is mainly collected by the lower water receiving groove 14 (see arrow Y2).

  As described above, most of the dew and rain water collected by the water receiving groove 14 in the film stopper member 10 flows along the longitudinal direction of the film stopper member 10 and flows out from the end of the film stopper member 10. It flows into 20 water flow paths (see arrow Z1 in FIG. 5). Specifically, it is as follows.

  Of the water that flows out from the end of the film stopper member 10, most of the water that flows out of the film stopper member 10 flows into the lower water receiving groove portion 27 located at the central portion in the left-right direction of the joint 20. On the other hand, the water flowing out from the end portion of the film stopper member 10 does not flow out to the outside of the film stopper member 10, but from the end portion of the film stopper member 10 to the back side of the film stopper member 10, that is, the lower surface of the bottom plate portion 11. There is also water that travels through 11c. The water that travels on the back side of the film stopper member 10 gradually flows down to the joint 20 side while passing through the gap between the film stopper member 10 and the joint 20.

  Thus, of the water that flows down from the back side of the film stopper member 10 to the joint 20 side, the water that has flowed into the upper water receiving groove portion 28 passes through the upper water receiving groove portion 28 as it is and passes through the central portion of the joint 20 in the left-right direction. It flows down to the lower water receiving groove 27. Here, since the upper water receiving groove portion 28 is inclined in the horizontal direction of the joint 20 toward the lower water receiving groove portion 27 side, the water that has flowed into the upper water receiving groove portion 28 is automatically lowered without stagnation. It flows down to the receiving groove 27. Of the water that flows down from the back side of the film stopper member 10 to the joint 20 side, the water that flows down to the middle water receiving groove portion 26 flows from the vertical groove portion 26a to the lower water receiving groove portion 27 through the horizontal groove portion 26b. Of the water flowing down from the back side of the film stopper member 10 to the joint 20 side, the water flowing down on the insertion groove 24, that is, the upper side surface 21 a of the joint 20, travels on the upper side surface 21 a, and receives the middle stage water receiver. It finally flows down to the lower water receiving groove 27 through the groove 26. As described above, the water flowing out from the end portion of the film stopper member 10 flows into the water passage of the joint 20 and is finally guided to the lower water receiving groove 27 and collected.

  In the lower water receiving groove 27, a flow from the upper portion side to the lower portion of the lower water receiving groove 27 is caused by the inclination of the joint 20 with the lower nozzle 32 side as the lower side, and flows into the lower water receiving groove 27. The dead water is discharged to a predetermined position such as the valley 18 by the hose 9 through the lower nozzle 32.

  Thus, in the joint 20 of the present embodiment, the water that enters the back side of the film stopper member 10 from the end of the water receiving groove 14 is collected by the upper water receiving groove 28 immediately after entering. Thereby, the time which water exists between the film stopper member 10 and the joint 20 can be shortened, and the rust of the film stopper member 10 can be prevented. Further, even if the water entering the back side of the film stopper member 10 is not recovered by the upper water receiving groove portion 28, it is recovered by the middle water receiving groove portion 26 outside the upper water receiving groove portion 28. The occurrence of rust can be reliably prevented. Furthermore, the upper water receiving groove portion 28 and the middle water receiving groove portion 26 are concentrated in the center portion in the left-right direction of the joint 20, specifically, in the range of 1/3 of the total length in the center portion in the left-right direction of the joint 20. It is provided to fit. For this reason, the water that has entered the back side of the film stopper member 10 can be collected before the water reaches the end of the joint 20 in the left-right direction, and the wide range of the portion of the film stopper member 10 that faces the joint 20 is wide. Can prevent exposure to water. As a result, generation of rust on the film stopper 10 can be effectively prevented. The joint 20 according to the present embodiment is a joint that connects the two film stopper members 10 to each other by inserting the film stopper member 10 only on one side in the left-right direction and attaching it to the end of the film stopper member 10. It can also be used as a protective cap instead of a member.

  Next, the dew collection structure 40 provided in the roof top part is demonstrated using FIG. As shown in FIG. 12, in the dew collection structure 40 provided on the roof top, the film stopper member 10 is held by the joint 20 with the front-rear direction aligned in a substantially horizontal direction as described above, and the width direction is changed. The state is substantially parallel to the horizontal plane (see straight line X1). The film stopper member 10 in this state has the water receiving grooves 14 on both sides in the width direction positioned at the same height, and each water receiving groove 14 has a substantially U-shaped cross section with respect to the horizontal plane (see the straight line X1). Or a substantially J-shaped groove is formed. This groove functions as a bowl-shaped portion that receives dew or rain water and guides it in a predetermined direction while holding the water.

  In the roof top dew collection structure 40 as described above, as shown in FIG. 12, dew generated on the inner surface of the film 2 and rainwater entering the greenhouse pass through the side wall 13 of the film stopper member 10. By dropping directly from the film 2, it flows into the water receiving grooves 14 on both the left and right sides and is collected.

  Specifically, regarding the dew generated on the inner surface of the film 2, the dew generated on the upper portion of the side wall portion 13 of the film 2 is collected by the water receiving groove 14 along the outer wall portion 13 y of the side wall portion 13. (See arrow Y3). Moreover, the dew produced in the upper part of the water receiving groove 14 of the film 2 is recovered by the water receiving groove 14 by dropping as it is (see arrow Y3).

  As for rainwater that enters the greenhouse, as described above, rainwater that enters from the break near the tip of the side wall 13 that is likely to be broken in the film 2 travels through the outer wall 13y of the side wall 13 or the film. By being directly dropped from 2, the water receiving grooves 14 on both the left and right sides are collected (see arrow Y3).

  As described above, most of the dew and rainwater collected by the water receiving groove 14 in the film stopper member 10 flows along the longitudinal direction of the film stopper member 10 and flows out from the end of the film stopper member 10. Thus, it flows into the water flow path of the joint 20 and is finally guided to the lower water receiving groove 27 and collected.

  In the dew collection structure 40 provided on the roof top, most of the water that flows into the lower water receiving groove 27 of the joint 20 is collected on the roof slope by the hose 9 connected to the lower nozzle 32. Guided to the joint 20 of the structure 40. The water introduced from the joint 20 of the roof top to the joint 20 of the roof slope portion by the hose 9 is sent to the valley 20 by the hose 9 from the upper nozzle 31 side of the joint 20 through the lower water receiving groove 27 and the lower nozzle 32. It is discharged to a predetermined position such as 18.

  As described above, the dew and rainwater are collected by the dew collection structure 40 located on each of the roof slope portion and the roof top portion. In particular, in the dew collection structure 40 located on the roof slope portion, dew generated on the inner surface of the film 2 is collected mainly by the upper water receiving groove 14, and rainwater entering the greenhouse from the tearing of the film 2 is mainly lower. It is collected by the water receiving groove 14 on the side. In addition, in the dew collection structure 40 located on the roof top, dew that flows through the inner surface of the film 2 does not flow in due to the action of gravity. The water receiving groove 14 has an advantageous effect on the collection of rainwater. Specifically, as shown in FIG. 12, in the dew collection structure 40 located on the roof top, rainwater that has entered from the contact portion with respect to the tip of the side wall portion 13 where the film 2 is easily torn as described above, It collects in the water receiving groove 14 along the outer wall portion 13 y of the side wall portion 13.

  Then, the pipe stop structure 50 (refer FIG. 1) used for fixation with respect to the arch pipe 3 of the film stop member 10 which concerns on this embodiment is demonstrated. The pipe stop structure 50 is a structure that maintains the crossed state of the arch pipe 3 and the film stop member 10 in the skeleton material crossing portion 7 of the greenhouse structure 1. The film stopper member 10 according to the present embodiment can correspond to at least two types of existing structures as the pipe stopper structure 50 depending on its characteristic shape and structure. Here, as an example of the existing pipe fastening structure 50, a first pipe fastening structure 50A using a wedge member and a second pipe fastening structure 50B using a wire having a predetermined curved shape will be described. .

  First, the first pipe fastening structure 50A will be described with reference to FIG. As shown in FIGS. 13A and 13B, the first pipe fastening structure 50A is fixed to the arch pipe 3 by sandwiching the arch pipe 3 in the radial direction (vertical direction in FIG. 13B). At the same time, the film stopper 10 and the arch pipe 3 are fixed to each other. In the following description, the direction in which the arch pipe 3 is sandwiched by the first pipe fastening structure 50A is referred to as “pipe clamping direction”.

  The first pipe fastening structure 50A supports the arch pipe 3 and the film fastening member 10 in a state of crossing each other and a coupling support member 51 for coupling the arch pipe 3 and the film fastening member 10 to each other; A wedge member 52 is provided for press-fixing the arch pipe 3 supported by the member 51 and the film stopper member 10. Each member of the coupling support member 51 and the wedge member 52 is an integral member made of a metal material such as stainless steel or aluminum alloy, or a resin material such as plastic.

  According to the first pipe stopper structure 50A, the arch pipe 3 and the film stopper member 10 in a state of crossing each other are restricted from moving in a direction (upward in FIG. 13) pressed from the arch pipe 3 side. The wedge member 52 is supported by the coupling support member 51 and is inserted into the insertion hole 51h for insertion of the wedge member 52 formed in the coupling support member 51 on the side opposite to the film stopper member 10 with respect to the arch pipe 3. The stopper member 10 is driven in a direction along the longitudinal direction (left and right direction in FIG. 13B). Accordingly, the arch pipe 3 and the film stopper member 10 are pressed against and fixed to the coupling support member 51 in a state where the arch pipe 3 is sandwiched between the film stopper member 10 and the wedge member 52.

  The coupling support member 51 is a member formed by bending a substantially rectangular plate member as a whole into a substantially U-shape or a substantially U-shape, and a pair of side plate portions 51a facing each other, and one of these side plate portions 51a. And an erected portion 51b that connects the pair of side plate portions 51a to each other in a manner erected between the pair of side plate portions 51a. In the first pipe retaining structure 50A, the arch pipe 3 is included between a pair of side plate portions 51a that have a substantially U-shape or a substantially U-shape together with the installation portion 51b.

  In the coupling support member 51, a notch 51c is formed from a portion of the side plate portion 51a on the installation portion 51b side to the installation portion 51b. The notch portion 51c corresponds to the axial direction of the arch pipe 3 of the portion of the side plate portion 51a on the side of the erection portion 51b and each portion of the erection portion 51b (FIG. 13 (a) corresponds to the left-right direction. Cut out the middle part. By the notch 51c, the side plate 51a extends from the base 51d that constitutes approximately half of the side opposite to the installation part 51b side, and from both ends in the pipe axial direction on the installation part 51b side of the base 51d to the installation part 51b side. It has the extended part 51e extended. Similarly, the notch 51c causes the erection part 51b to have a pair of erection piece parts 51f as parts connecting the pair of side plate parts 51a on both sides in the pipe axis direction. That is, as the erection part 51b that connects the pair of side plate parts 51a, the erection piece part 51f is erected between a pair of extending parts 51e that are opposed to each other at two locations on both ends in the pipe axis direction. Exists. In the following description, with respect to the pipe clamping direction, the erection part 51b side (upper side in FIGS. 13A and 13B) of the coupling support member 51 is referred to as “erection part side” and the opposite side (lower side in the same figure). Is “open side”.

  The coupling support member 51 has a pair of skeleton member locking portions 51g on the installation portion side. The pair of skeletal material locking portions 51g support the film stopper member 10 pressed by the wedge member 52 via the arch pipe 3 from the open side in the pipe clamping direction toward the erection portion side. The pair of skeletal material locking portions 51g are arranged in a direction opposite to each other in the pipe axial direction from both erected piece portions 51f so that the opening width in the pipe axial direction is narrowed at the opening end of the cutout portion 51c on the erected portion 51b side. It is a protruding piece part. With such a pair of skeletal material locking portions 51g, the film stopper member 10 is in contact with the pair of skeleton material locking portions 51g from the open side (the lower side in FIGS. 13A and 13B), It is supported by the coupling support member 51. That is, the pair of skeleton member locking portions 51g are supported in a state in which the film stopper member 10 is locked so as to restrict the movement of the film stopper member 10 that is pressed from the opening side toward the installation portion side in the pipe clamping direction. To do.

  In contrast to the coupling support member 51 having the above-described configuration, the film stopper member 10 abuts the distal end sides of the left and right edge wall portions 15 from the inside of the coupling support member 51 to the skeleton material locking portions 51g. In addition, the upper portion of the side wall portion 13 is supported in a state of protruding outward from the notch portion 51c. In this way, the pair of skeleton material locking portions 51g support the arch pipe 3 via the film stopper member 10 on the side opposite to the side where the wedge member 52 contacts the arch pipe 3 in the pipe clamping direction. To do.

  Further, in the coupling support member 51, the insertion hole 51h for inserting the wedge member 52 is formed in the base portion 51d of the side plate portion 51a. The insertion hole 51h is formed to have a shape / dimension corresponding to the shape / dimension of the wedge member 52. The insertion hole 51h is provided at a position overlapping the opposing direction of the pair of side plate portions 51a, and the wedge member 52 is inserted so as to penetrate the insertion hole 51h (see FIG. 13B). That is, the wedge member 52 is inserted so as to pass through the pair of side plate portions 51 a with the insertion direction, which is the longitudinal direction thereof, extending along the extending direction (longitudinal direction) of the film stopper member 10.

  The wedge member 52 has a shape in which both long-side portions of the rectangular plate-like member are bent substantially at right angles to the same side (front side), has a substantially rectangular shape in plan view, and has a transverse cross section. Visually U-shaped or U-shaped. Therefore, the wedge member 52 has a substantially rectangular flat plate-shaped bottom plate portion 52a and a pair of side wall portions 52b provided along the long side of the bottom plate portion 52a.

  In the wedge member 52, the side wall 52b has a height (the vertical dimension in the figure) of the side wall 52b in the longitudinal direction on the substantially half of one side in the longitudinal direction (left side in FIG. 13B). There is an inclined portion 52c that gradually decreases toward the end side. That is, the inclined portion 52c is formed such that the shape of the upper end surface (the upper surface in FIG. 13B) of the side wall portion 52b is lowered toward the end portion on one side in the longitudinal direction with respect to the planar bottom plate portion 32. Tilt. Accordingly, the side wall portion 52b has a sloped surface along the slope of the sloped portion 52c in the half of one side in the longitudinal direction on the upper end surface thereof, and the portion substantially continuous with the sloped surface portion in the remaining half. It has a flat surface 52d parallel to the bottom plate portion 52a. The inclination angle of the inclined portion 52c depends on the shape and dimensions of the arch pipe 3 and the film stopper member 10, but is, for example, 5 to 30 ° with respect to the longitudinal direction of the wedge member 52 (flat bottom plate portion 52a). An angle within the range of.

  The wedge member 52 having the above configuration is inserted into the insertion holes 51h formed in the pair of side plate portions 51a on the open side with respect to the arch pipe 3, so that the wedge member 52 with the pair of skeleton material locking portions 51g The arch pipe 3 is sandwiched therebetween, and the arch pipe 3 is pressed and fixed. In this embodiment, the wedge member 52 sandwiches the arch pipe 3 between the pair of skeleton material locking portions 51 g via the film stopper member 10 and fixes the arch pipe 3 in a state of being pressed against the arch pipe 3.

  In the first pipe fastening structure 50A having the above-described configuration, the film fastening member 10 is latched and supported from the inside by the pair of frame material latching portions 51g with respect to the coupling support member 51 and the coupling support member 51. With the arch pipe 3 positioned between the side plate portions 51a, the wedge member 52 is inserted into the insertion hole 51h so as to penetrate the pair of side plate portions 51a. Here, the wedge member 52 is inserted into the insertion hole 51h by being driven by a hammer or the like from the inclined portion 52c side of the side wall portion 52b.

  As the wedge member 52 is inserted into the insertion hole 51h, the arch pipe 3 is pressed to the installation part side in the pipe clamping direction as a reaction of the wedge member 52 pressing the coupling support member 51 to the open side from the insertion hole 51h. The Thereby, the film stopper member 10 and the arch pipe 3 that are supported by the pair of skeleton member locking portions 51g are pressed and fixed, and the crossed state is maintained.

  On the other hand, when the wedge member 52 is inserted into the insertion hole 51h and the arch pipe 3 and the film stopper member 10 are held, the wedge member 52 is struck with a hammer or the like from the distal end side in the insertion direction. 52 is extracted from the insertion hole 51h. Thereby, holding | maintenance of the arch pipe 3 and the film stopper member 10 is cancelled | released.

  Next, the 2nd pipe stop structure 50B is demonstrated using FIG. 14 and FIG. The second pipe stop structure 50 </ b> B has a pair of fixtures 60. The fixture 60 is formed by bending both ends of a metal wire into a predetermined shape. For example, when the outer diameter of the arch pipe 3 is about 2 to 3 cm, the fixture 60 is made of a metal wire having a wire diameter of about 3 mm and a length of about 20 cm. The fixing tool 60 fixes the film stopper member 10 and the arch pipe 3 to each other by being locked to the film stopper member 10 in a state where the arch pipe 3 is pressed against the film stopper member 10.

  As shown in FIG. 14, the fixture 60 is provided at the linear intermediate portion 61, the first curved portion 62 provided at one end portion of the intermediate portion 61, and the other end portion of the intermediate portion 61. And a second curved portion 63.

  The first curve portion 62 is provided with an outer fitting portion 62a formed in a substantially semicircular arc shape corresponding to the outer diameter of the arch pipe 3 from one end portion of the intermediate portion 61, and this outer fitting portion 62a. A first hook 62b is provided at the end opposite to the intermediate portion 61 side. The first hooking portion 62b is substantially tangential to the arc shape of the outer fitting portion 62a from the end opposite to the intermediate portion 61 side of the outer fitting portion 62a, and is intermediate in the center axis direction view of the arc shape. A straight portion 62c that extends in a direction that forms an obtuse angle with respect to the axial direction of the portion 61, and a straight portion 62c that is folded back from the end on the extending side of the straight portion 62c along the direction of the straight portion 62c. And a locking portion 62d having a substantially J shape (hook shape). The angle formed between the surface along which the substantially arc shape of the outer fitting portion 62a is aligned and the surface along which the approximately J-shaped shape of the first hooking portion 62b is approximately 90 °.

  The second curved portion 63 is provided with a gripping portion 63a formed in a substantially semicircular arc shape from the other end portion of the intermediate portion 61, and the end portion of the gripping portion 63a opposite to the intermediate portion 61 side. In addition, a second hooking portion 63b is provided. The grip portion 63a is a portion that is gripped by an operator or the like when the fixture 60 is used. The arcuate size (diameter) formed by the gripping portion 63a is about half of the outer fitting portion 62a. The gripping part 63a is formed so that the surface along which the substantially arc shape extends is substantially orthogonal to the surface along which the approximately arc shape of the outer fitting part 62a extends. The second hook portion 63b is substantially tangential to the arc shape of the grip portion 63a from the end opposite to the intermediate portion 61 side of the grip portion 63a, and the second hook portion 63b of the intermediate portion 61 is viewed in the central axis direction of the arc shape. The linear portion 63c extends in a direction substantially perpendicular to the axial direction, and the locking portion 63d is bent substantially at right angles to the linear portion 63c from the end of the linear portion 63c on the extending side. The rising direction of the locking portion 63d from the straight portion 63c is the rising direction of the outer fitting portion 62a with respect to the intermediate portion 61 and the rising direction of the end portion of the locking portion 62d that is substantially J-shaped with the straight portion 62c. Is almost the same.

  The second pipe stopping structure 50B by the fixing tool 60 as described above is used as follows. A pair of fixtures 60 are used to fix the film stopper 10 to the arch pipe 3 by the second pipe fixing structure 50B, and the fixtures 60 are engaged with the edge wall portions 15 on both the left and right sides of the film stopper 10. In this state, the arch pipe 3 is held in pressure contact with the film stopper 10.

  When the arch pipe 3 and the film stopper member 10 are fixed by the fixture 60, as shown in FIGS. 15A to 15C, the arch pipe 3 contacts the film stopper member 10 from the lower surface 11c side. In addition, the film stopper member 10 is disposed in a direction substantially orthogonal to the longitudinal direction of the film stopper member 10. In such an arrangement relationship between the arch pipe 3 and the film stopper member 10, one fixing tool 60 connects the first hook portion 62 b of the first curved portion 62 from the lower side of the film stopper member 10 to the edge wall portion 15. The outer fitting part 62a having a substantially semicircular arc shape is applied from the lower side of the arch pipe 3 (opposite side to the film stopper member 10 side).

  Next, the second curved portion 63 side of the fixture 60 that is located away from the film stopper member 10 is brought closer to the film stopper member 10 side mainly by the elastic deformation of the intermediate portion 61, and the second hook portion 63b. Is hooked on the edge wall 15. Here, when bringing the second curved portion 63 side of the fixture 60 closer to the film stopper member 10 side, the grip portion 63a is used as a grip portion. Thus, according to the fixture 60, the first hook 62 b is locked to the edge wall portion 15 and the outer fitting portion 62 a is fitted to the arch pipe 3. The second hook portion 63 b that does not reach the edge wall portion 15 in the state is locked to the edge wall portion 15 by the elastic deformation of the fixture 60. As a result, the arch pipe 3 to which the outer fitting portion 62a is applied is brought into pressure contact with the lower side surface 11c of the film stopper member 10 by the restoring force of the fixing portion 60 mainly of the intermediate portion 61.

  Similarly, the other fixture 60 is also locked to the film stopper member 10 in a state where the arch pipe 3 is pressed against the film stopper member 10. However, since the pair of fixtures 60 are locked with respect to the edge wall portions 15 on both sides with respect to the film stopper member 10, for example, as shown in FIG. When viewed from a direction perpendicular to the longitudinal direction of the film, the pipe is mounted in a symmetrical manner with respect to the pipe axial direction and the longitudinal direction of the film stopper member 10.

  On the other hand, from the state in which the fixture 60 is mounted with the arch pipe 3 being held with respect to the film stopper member 10, the second hook portion 63 b is pulled up from the edge wall portion 15 by the elastic deformation of the fixture 60 and removed. Further, the first hook portion 62b is detached from the edge wall portion 15, whereby the fixture 60 is removed, and the holding of the arch pipe 3 and the film stopper member 10 is released. Again, when removing the second hook 63b from the edge wall 15, the grip 63a is used as the grip.

  As described above, according to the second pipe fastening structure 50B using the pair of fixtures 60, the arch pipe 3 and the film fastening member 10 can be fastened to each other with a single touch without using a tool. Workability can be obtained. Moreover, since the fixture 60 is a structure in which the wire is bent, it is advantageous in terms of cost in comparison with the first pipe fastening structure 50A.

It becomes a part which forms a part. Due to the protrusion 73d, the dimension in the width direction of the film fixing groove 72 becomes discontinuously narrow with respect to the same dimension at the position of the inclined part 73c.

  The edge wall portion 75 that forms the water receiving groove 74 is a portion formed so as to rise substantially perpendicularly to the bottom plate end portion 71y from the outer end portion of the bottom plate end portion 71y, and protrudes inward to the upper end portion thereof. And a bulging portion 75c. The bulging portion 75c is a portion that protrudes inward so that the tip end portion (upper end portion) of the edge wall portion 75 forms a substantially semicircular shape when viewed in cross section.

  The film stopper member 10 having the above-described configuration includes a bottom plate middle portion 71x of the bottom plate portion 71 and a bottom plate portion 11 as a portion for forming a film fixing groove 72 having a substantially trapezoidal shape whose upper side is opened in a cross section. It has the vertical part 73b located in order toward the upper side, the inclination part 73c, and the protrusion part 73d. A portion between the projecting portions 73 d facing each other is a portion opened in the film fixing groove 72. For the film fixing groove 72, as in the case of the above-described embodiment, the wavy linear spring 8 is used, and the film 2 is fixed.

  In the film stopper member 70 having the above configuration, a film stopper groove portion that forms the film fixing groove 72 is constituted by the bottom plate intermediate portion 71x of the bottom plate portion 71 and the pair of side wall portions 73 facing each other. . And the dew receiving part which forms the water receiving groove 74 is comprised by the baseplate edge part 71y of the baseplate part 71, the side wall part 73, and the edge wall part 75 in the both right and left sides of this film stop groove part. As described above, in the film stopper member 70 of the present embodiment, unlike the film stopper member 10 of the above-described embodiment, the side wall portion 73 rising from the bottom plate portion 71 is provided as a single wall-shaped portion, and is fixed to the film. The groove 72 and the water receiving groove 74 are commonly used as portions forming the respective grooves.

  In addition, as described above, an aluminum material is preferably used as the material for the film stopper member 70 of the present embodiment formed by extrusion or the like from the viewpoint of durability due to rust prevention. That is, for the film stopper member 70 of the present embodiment, an example of a preferred embodiment is an extruded product made of an aluminum material.

  As shown in FIG. 21, the film stopper member 70 according to the present embodiment is connected by the joint 20 and constitutes the dew collection structure 40 together with the joint 20 as in the film stopper member 10 of the first embodiment. That is, in the joint 20, the insertion groove 24 that receives the insertion of the film stopper member 70 has the upper side surface 21 a of the substrate portion 21 as a sliding surface with respect to the lower side surface 71 c of the bottom plate portion 71 that is the lower surface of the film stopper member 70. . Moreover, the insertion groove 24 makes the clamping surface 23a of the clamping part 23 into a sliding surface with respect to the outer side surface 75d of the edge wall part 75 used as the outer side end surface of the film stop member 70 in the width direction. Moreover, the insertion groove 24 makes the latching protrusion 23b of the clamping part 23 the sliding part with respect to the bulging part 75c of the edge wall part 75 used as the upper end part in the both ends of the width direction of the film stopper member 70. .

  Moreover, the same modification as the film stopper member 10 of the first embodiment can be applied to the film stopper member 70 of the present embodiment. That is, as a modification of the film stopper member 70, as shown in FIG. 22A, the film fixing groove 72 is provided at a position where the center position in the width direction is shifted from the center position in the width direction of the bottom plate portion 71. The film stopper member 70A having a configuration and the film stopper member 70B having a configuration in which the vertical portion 73b (see FIG. 19) rising substantially vertically from the bottom plate portion 71 in the side wall portion 73 is omitted as shown in FIG. It is done.

  In particular, in the film stopper member 70A of the modification shown in FIG. 22A, the width direction center position G1 of the film fixing groove 72 is the width direction dimension of the bottom plate portion 71 in the width direction. It is shifted to the right by H1. In the film stopper member 70A having such a configuration, the width dimension J1 of the water receiving groove 74A on one side in the width direction (left side in FIG. 22A) is the water receiving side on the other side (right side in the figure). It becomes larger than the width dimension J2 of the part 74B.

  According to the film stoppers 10 and 70 and the dew collection structure 40 of the embodiment as described above, in a structure having a portion for receiving dew and rainwater, versatility and strength can be improved, and a mountable spring The number can be easily increased. Actions and effects obtained by the film stopper members 10 and 70 and the dew collection structure 40 according to the above-described embodiment will be specifically described.

  According to the film stopper member 10 (70) according to the above-described embodiment, not only when it is provided on the roof slope portion (see FIG. 11) but also when it is provided on the roof top (see FIG. 12). Even dew and rainwater can be collected. That is, according to the film stopper member 10 (70), it has the edge wall part 15 (75) which forms the water receiving groove 14 (74) which receives water with the baseplate part 11 (71) and the side wall part 13 (73). Therefore, the water receiving groove 14 (74) can be made to function as a bowl-shaped portion at any location of the roof slope portion and the roof top portion. Thereby, the freedom degree of the arrangement position in the greenhouse structure 1 can be improved, and versatility can be improved.

  In this regard, in the case of the conventional film stopper member 110 as shown in FIG. 25, the film stopper member 110 is inclined with respect to the horizontal plane (see the straight line X1) in order to cause the dew receiving portion 130 to function as a bowl-shaped portion. It is necessary to provide it (see FIG. 25B). Further, in the conventional film stopper member 110, nothing exists below the lower side wall part 122 that forms the film stopping groove part 120, so that, for example, in the contact portion of the lower side wall part 122 with the film 102 Rainwater that enters the greenhouse due to film tearing cannot be received and retained.

  On the other hand, according to the film stopper member 10 (70) according to the above-described embodiment, the roof slope particularly relates to rainwater that enters the greenhouse from the tearing of the film 2 that has been relatively difficult to collect by the prior art. Rainwater can be easily recovered by the water receiving groove 14 (74) located mainly at the lower part and the water receiving grooves 14 (74) on both sides at the roof top part.

  Moreover, about the linear film stopper member 10 (70) constructed | assembled with respect to the some arch pipe 3 provided in the greenhouse structure 1 by the arrangement | positioning error of a arch pipe 3, a shape error, etc., There may be a case where a position where the film stopper member 10 (70) intersects with each other does not follow the linear shape of the film stopper member 10 (70). In this case, for example, as shown in FIG. 23, the arch pipe 3 and the film stopper member 10 (70) are mutually connected by the pipe stopper structure 50 (50A) at the intersection of the arch pipe 3 and the film stopper member 10 (70). By being fixed, the film stopper member 10 (70) may bend and have a concave portion. In the example shown in FIG. 23, among the three arch pipes 3 arranged in the left-right direction, the middle arch pipe 3X is positioned lower than the other arch pipes 3 and the arch pipes in the film stopper member 10 (70). A recessed portion (see arrow P1) is generated in the portion fixed to 3X. In the example shown in FIG. 23, the first pipe stopper structure 50 </ b> A having the wedge member 52 is shown as the pipe stopper structure 50.

  When such a recessed portion of the film stopper member is generated, for example, according to a conventional film stopper member as shown in FIG. 25, the dew collected by the dew receiving portion 130 tends to overflow in the recessed portion. The phenomenon that the recovery of the water is not sufficiently performed occurs. In this regard, according to the film stopper member 10 (70) according to the above-described embodiment, the edge wall portion that forms the water receiving groove 14 (74) that receives water together with the bottom plate portion 11 (71) and the side wall portion 13 (73). 15 (75), the dew and rain collected in the water receiving groove 14 are firmly held in the water receiving groove 14. For this reason, even if it is a case where the dent part of the film stop member 10 (70) as shown in FIG. 23 arises, the overflow of the water from the water receiving groove 14 can be prevented. Thereby, the dew and rainwater collected by the water receiving groove 14 can be reliably guided to the joint 20.

  Moreover, according to the film stopper member 10 (70) according to the above-described embodiment, as described above, at least two types of existing pipe stopper structures 50 used for fixing the film stopper member 10 (70) to the arch pipe 3 are used. (See FIGS. 13 to 15). This means that the film stopper member 10 (70) includes an edge wall portion 15 (75) that forms a water receiving groove 14 (74) that receives water together with the bottom plate portion 11 (71) and the side wall portion 13 (73). Based. That is, the portion including the edge wall portion 15 (75) is shared as the portion that receives the action from the members constituting the pipe stopper structure 50 in each of the two types of pipe stopper structures 50A and 50B as described above. The

  Specifically, when the first pipe stopper structure 50 </ b> A using the wedge member 52 is employed as the pipe stopper structure 50 (see FIG. 13), the edge wall portion 15 (75) is a pair of the coupling support member 51. When the film stopper members 10 and 70 are supported on the skeleton member locking portion 51g, the contact portions to the coupling support member 51 are provided. Moreover, when the 2nd pipe stop structure 50B using the fixing tool 60 which is a wire which has a predetermined | prescribed curved shape is employ | adopted as the pipe stop structure 50 (refer FIG. 15), the edge wall part 15 (75) is It becomes a part which receives the latching effect | action of the fixing tool 60. FIG. Since the plurality of pipe fastening structures 50 can be accommodated in this way, the structure of the pipe fastening structure 50 can be appropriately changed according to the position and shape of the fixing portion of the film fastening member 10 (70) with respect to the arch pipe 3. In view of this, versatility can be improved.

  Further, regarding the number of springs that are stacked and mounted in the depth direction of the film fixing groove in order to fix the film 2, the number of springs is conventionally limited to about three at the maximum in terms of structure. This is because, in the conventional film fixing member, the portion that forms the film fixing groove and the portion that is locked or supported by the fixing metal fitting in the pipe fixing structure 50 are a common portion. This is based on the fact that the dimension of the portion for forming the film fixing groove is conventionally limited to a certain range in relation to the metal fitting. In other words, according to the conventional film fixing member, if the number of springs that can be mounted in an overlapping manner is increased by enlarging the part that forms the film fixing groove, it is necessary to change the dimensions of the fixing metal fitting. It was necessary to make the metal fittings.

  In this regard, according to the film stopper member 10 (70) according to the above-described embodiment, for example, FIG. 24 shows, without changing the dimensions or the like of the members (the coupling support member 51, the fixture 60, etc.) constituting the pipe stopper structure. As shown, it is possible to increase the number of springs 8 that are mounted in the depth direction of the film fixing groove 12 (72) to about five. FIG. 24 shows a state in which the film stopper member 10 of the first embodiment includes five springs 8. The fact that the number of springs can be increased in this manner is that, in the film stopper member 10 (70) according to the above-described embodiment, as described above, the pipe stopper is independent of the portion that forms the film fixing groove 12. As a part that receives the action from the members constituting the structure 50, the edge plate 15 (75) that forms the water receiving groove 14 (74) that receives water together with the bottom plate part 11 (71) and the side wall part 13 (73) is provided. Based on that.

  As described above, in the conventional film fixing member, when the height of the side wall portion for forming the film fixing groove is increased in order to deepen the film fixing groove, the dimension corresponds to the metal fitting for fixing to the arch pipe 3 in terms of dimensions. However, according to the film stoppers 10 and 70 of the present embodiment, the edge wall portion 15 (75) is provided at a position projecting to the sides on both sides from the portion where the film fixing groove 12 (72) is formed. Therefore, in the relationship with the metal fitting for fixing to the arch pipe 3, there is little influence due to the height of the side wall part 13 (73) forming the film fixing groove 12 (72) being increased, and the side wall part 13 (73). It becomes easy to increase the number of the springs 8 that can be mounted by increasing the height of. By increasing the number of springs 8 that can be mounted, for example, in a portion where a large number of films such as a wife surface film, a roof surface film, a windproof / insectproof film, etc. in the greenhouse structure 1 overlap, Can be easily handled.

  Moreover, according to the film stopper member 10 (70) which concerns on embodiment mentioned above, the edge wall part 15 which forms the water-receiving groove | channel 14 (74) which receives water with the baseplate part 11 (71) and the side wall part 13 (73). Since (75) is provided, it is possible to easily obtain sufficient strength as a skeleton material constituting the framework of the greenhouse structure 1. That is, the edge wall portion 15 (75) is a portion that rises like a wall on both sides in the width direction over the entire length of the film stopper member 10 (70), and this edge wall portion 15 (75) functions as a reinforcing portion. In particular, the strength of the film stopper 10 (70) in the longitudinal direction can be improved.

  Moreover, regarding the strength of the film stopper member 10 (70), as described above, the height of the side wall portion 13 (73), which is the portion forming the film fixing groove 12 (72), can be made higher than the conventional one. Contributes to strength improvement. In particular, in the film stopper member 10 of the first embodiment, the side wall portion 13 is a folded portion of a plate-like member, and includes a portion where the plate-like portions overlap. By using a steel material, a very high strength can be obtained.

  Thus, according to the film stopper member 10 (70) according to the above-described embodiment, sufficient strength can be obtained, and deformation and bending can be suppressed in the longitudinal direction. Further, the strength of the film stopper member 10 (70) is improved, so that the length of the single film stopper member 10 (70) is increased and the arrangement pitch of the connecting portions of the plurality of film stopper members 10 (70) is increased. can do. This is very advantageous in reducing the number of parts constituting the framework of the greenhouse structure 1, omitting labor for manufacturing the greenhouse structure 1, and cost reduction.

  Further, in the film stopper member 10 (70) according to the above-described embodiment, the side wall portion 13 (73) includes the vertical portion 13b (73b) rising substantially vertically from the bottom plate portion 11 (71) and the vertical portion 13b (73b). ) To be inclined toward the other side wall 13 (73), and to the tip of the inclined portion 13c (73c), on the inner side of the film fixing groove 12 (72). It has a protruding portion 13d (73d) that protrudes. According to such a configuration, the spring 8 used when fixing the film 2 can be firmly held in the film fixing groove 12.

  In particular, for example, as shown in FIG. 24, in the case where five springs 8 are used that are stacked and mounted in the depth direction of the film fixing groove 12 (72), the spring 8 with respect to the film stopper member 10 (70) is used. The attachment / detachment work can be facilitated. Specifically, for example, as shown in FIG. 18, according to the structure in which the vertical portion 13b (73b) is omitted in the side wall portion 13 (73), the dimension in the width direction of the film fixing groove 12 (72) from the lower side to the upper side. Therefore, the amount of deformation of the spring 8 in the width direction becomes larger when the spring 8 attached to the upper side is attached to and detached from the film stopper member 10, and it is necessary to resist the elastic force of the spring 8. Become.

  In this regard, like the film stopper member 10 (70) according to the above-described embodiment, the side wall portion 13 (73) includes the vertical portion 13b (73b), the inclined portion 13c (73c), and the protruding portion 13d (73d). It can relieve | moderate that the dimension of the width direction of the film fixing groove 12 becomes narrow. For this reason, it is possible to obtain a good attachment / detachment workability for the plurality of springs 8 and to obtain a reliable holding property for the plurality of springs 8 by the protruding portion 13d (73d) at the upper end.

  Further, in the film fixing member 10 (70) according to the above-described embodiment, the film fixing groove 12 (72) is provided at a position where the center position in the width direction is shifted from the center position in the width direction of the bottom plate portion 11 (71). The structure (refer FIG. 16, FIG. 22 (a)) currently used is employ | adopted suitably. According to such a configuration, in the roof slope portion, the film stopper member 10 (70) is disposed so that the relatively wide water receiving groove 14A (74A) is positioned on the upper side, thereby receiving water that receives dew. Even if the capacity of the receiving groove 14 can be relatively increased and a large amount of dew is generated or a portion where the film stopper member 10 (70) is bent and recessed is formed (see FIG. 23), It becomes possible to collect dew and rain water more reliably without overflowing the water receiving groove 14.

  In the dew collection structure 40 according to the above-described embodiment, the joints 20 that connect the film stoppers 10 (70) to each other and receive the dew and rainwater collected by the film stoppers 10 (70) are opposite to each other. On both sides in the front-rear direction, there are nozzles 31, 32 to which the hose 9 is connected. According to such a configuration, for example, as shown in FIG. 10, the joint 20 located on the roof slope portion and the joint 20 located on the roof top portion can be connected to each other by the hose 9. Thereby, for example, in comparison with a configuration in which the hose 9 is arranged with respect to a predetermined place such as the valley 18 from each of the joints 20 located on the roof slope portion and the roof top portion, the joint 20 located on the roof top portion. It is possible to use a short hose as the hose 9 connected to the cable, and it is possible to reduce costs and improve the design appearance.
