Description

  More specifically, the present invention relates to a valley trough for a vinyl house disposed along the longitudinal direction of a valley between adjacent vinyl houses, and more specifically, condensate water generated on the inner surface of a sheet stretched on a house roof is removed from the house. This is related to the trough for a vinyl house that can be discharged into the house.

  2. Description of the Related Art Conventionally, vinyl houses for agriculture are of a continuous building type in which houses are juxtaposed, and these are provided with valley troughs for vinyl houses so that water does not collect in the roof valleys of the vinyl houses. Moreover, since it is necessary to adjust the temperature and humidity in the house according to the crops and other plants to be cultivated, the vinyl house constructed for agriculture is provided with an opening for ventilation in the roof valley. It was a general structure.

  On the other hand, since a large amount of water is used in the house and the room temperature is high, a large amount of dew condensation occurs on the inner surface of the sheet for forming the house. Condensation generated on the roof part descends to the valley at the inner side of the seat. If such condensed water falls on the soil in the house, it will have a significant adverse effect on the crops (for example, root rot, disease occurrence, poor growth, etc.). It has been proposed (see, for example, Patent Document 1).

  This is because a dew condensation receiving part that catches the flow of dew condensation on the inner surface of the sheet is formed at the back side of the sheet fixing groove provided at the upper end of the side wall of the valley wall. A waterfall hole is provided, and a groove-shaped saddle piece that receives the flow of condensed water is attached to the lower side of the waterfall hole, and the lower part of the saddle piece is connected to the inside of the trough.

  However, as described above, a saddle piece or the like is required, and a configuration for attaching the same is complicated, and in recent years, a trough as shown in FIG. 7 is often used.

The sheet fixing groove 300 having a dovetail shape in a cross-sectional view continuous with the side wall 200 is formed on each of the left and right side walls 200, 200 extending upward from the bottom wall 100 and extending upward to form a trough. In addition, a dew receiving piece 500 is continuously provided by extending the tip from the upper lip portion 400 forming the opening edge of the sheet fixing groove 300 to the outer side obliquely upward, and the inner surface of the sheet. This dew condensation flows out through the dew receiving piece portion 500 into the bag. Reference numeral 600 denotes an opening of the sheet fixing groove 300.
No. 6-2535

  However, in the structure shown in FIG. 7, since the dew receiving piece 500 is extended upward from the sheet fixing groove 300, a special fastener is required to attach the valley trough to the house construction pipe. It was a factor that increased the cost.

  That is, when constructing a vinyl house, the vinyl sheet uses a rail-shaped sheet fastener having a sheet fixing groove, and a fastener for attaching the sheet fastener to the house construction pipe is generally used. It is used.

  However, in the above structure, since the dew receiving piece 500 is extended upward from the sheet fixing groove 300, the dew receiving piece 500 becomes in the way and a versatile fastener cannot be used. Tools are needed.

  Further, in the above structure, there is a possibility that the sheet forming the roof and the upper lip portion 400 may be in close contact with each other. There was a risk that it could not be performed reliably.

  Further, since the upper lip 400 projects outward from the sheet fixing groove 300 formed on the upper side of the valley, when the valley is disposed in the valley between the houses having a predetermined width, The effective volume (volume as a water channel that can drain the received water) V formed below the sheet fixing groove 300 could not be increased.

  An object of the present invention is to provide a trough for a vinyl house that can solve the above-mentioned problems.

According to the first aspect of the present invention, vinyl which is disposed along the longitudinal direction of the valley between adjacent vinyl houses and which can discharge condensed water generated on the inner surface of the sheet stretched on the house roof to the outside of the house. It is a trough for a house, and a sheet fixing groove having a cross-sectional dovetail shape that is continuous with the side wall is formed on the upper part of the left and right side walls that extend upward from the bottom wall while forming a ridge. The sheet fixing groove is bent by bending the front end of the side wall once outward and downward, and a lower lip portion that forms an opening edge of the sheet fixing groove, and is continuous with the lower lip portion. A sheet receiving surface formed substantially in parallel with the sheet receiving surface, the tip is bent inward, and the tip is folded back into a hairpin shape inside to form a flat shape. An upper lip that forms the opening edge of It has a height from the sheet receiving surface of the upper lip, and lower than the height of the sheet receiving surface of the lower lip.

  According to a second aspect of the present invention, in the configuration according to the first aspect, a plurality of convex portions that prevent the upper surface of the lip portion and the sheet from being adhered to each other are formed on the upper lip portion of the sheet fixing groove. Has characteristics.

  According to a third aspect of the present invention, in the configuration according to the first or second aspect, a concave condensed water introducing portion is formed in the upper lip portion so as to face the opening of the sheet fixing groove. Also has features.

(1) In the present invention according to claim 1, the dew condensation water generated on the inner side surface of the sheet that is disposed along the longitudinal direction of the valley between adjacent vinyl houses can be discharged out of the house. It is a trough for a vinyl house, and a sheet fixing groove having a cross-sectional dovetail shape continuous with the side wall is formed at the upper part of the left and right side walls that gradually expand from the bottom wall to form a trough. formed, the sheet fixing groove is curved formed by bending toward the distal end of the side wall once outward downward, and a lower lip which forms the opening edge of the sheet fixing groove, continuously with the lower lip, A sheet receiving surface formed substantially parallel to the side wall, a sheet receiving surface that is continuous with the sheet receiving surface, the front end is bent inward, and the front end is folded inward into a hairpin shape to form a flat shape. Upper lip that forms the opening edge of the fixing groove When have, a height from the sheet receiving surface of the upper lip, in order to have the lower than the height of the sheet receiving surface of the lower lip, for example, for ventilation of the valley between adjacent plastic greenhouse As described above, when a sheet having a skirt that can be rolled up is disposed, the inner side surface in the vicinity of the skirt of the sheet is separated from the upper lip, and is close to or in contact with the lower lip. Condensation generated on the inner surface of the sheet passes through the lower lip and flows into the valley, or is blocked by the lower lip and flows into the valley through the sheet fixing groove, and the condensed water is discharged. It can be discharged reliably. In addition, since the sheet fixing groove is formed at the uppermost part of the valley, the effective volume formed below the sheet fixing groove (the volume as a water channel capable of draining received water) is increased. It is possible to cope with heavy rain.

  (2) According to the second aspect of the present invention, the plurality of convex portions that prevent the upper surface of the lip portion and the sheet from sticking to each other are formed on the upper lip portion of the sheet fixing groove. In addition, in the case where the above-described hoistable sheet for ventilation is not provided, or even if it is provided, the sheet is formed in the vicinity of the end face of the house in which the roof forming sheet is clamped in the sheet fixing groove. Since it does not adhere to the upper lip surface, it is possible to guide the dew condensation that has occurred on the inner surface of the sheet to the sheet fixing groove. Can do.

  (3) In the present invention described in claim 3, the condensation formed on the inner surface of the sheet is formed by forming a concave condensed water introducing portion in the upper lip portion so as to face the opening of the sheet fixing groove. It becomes possible to guide smoothly by the sheet fixing groove, and the effects (1) and (2) can be further enhanced.

The present invention is a valley trough for a vinyl house that is disposed along the longitudinal direction of a valley between adjacent vinyl houses, and that allows dew condensation generated on the inner surface of the sheet stretched on the roof of the house to be discharged outside the house. there are, at the top of the right and left side walls forming a trough and extending upward while gradually diverging from the bottom wall, to form a sheet fixing groove of cross section dovetail shape which is continuous with the side wall, the sheet fixing groove Is formed by bending the tip of the side wall outward and downward once, forming a curve, and forming a lower lip portion that forms an opening edge of the sheet fixing groove, and the lower lip portion, and substantially parallel to the side wall. The sheet receiving surface is continuous with the sheet receiving surface, the leading end is bent inward, and the leading end is folded inwardly into a hairpin shape to form a flat shape, forming the opening edge of the sheet fixing groove. has an upper lip portion, wherein the upper The height from the sheet receiving surface of-up unit, in which lower than the height of the sheet receiving surface of the lower lip.

  This valley trough can be suitably used for a continuous-type vinyl house where a ventilation sheet that can be rolled up is suspended from a valley portion of an adjacent vinyl house so that the inside of the house can be appropriately ventilated. In addition, in the vicinity of the wife portion in the valley portion of such a continuous-type vinyl house, a roof forming sheet is clamped in the sheet fixing groove, and the ventilation sheet is suspended so as to cover the sheet. ing.

  Therefore, when the Motoya tsumugi is used, the inner side surface in the vicinity of the hem portion of the ventilation seat is separated from the upper lip portion and is close to or in contact with the lower lip portion. The condensed dew passes through the lower lip and flows into the valley, or is blocked by the lower lip and flows out into the valley through the sheet fixing groove, and the condensed water is surely discharged. Can do.

  On the other hand, the dew condensation generated on the inner surface of the roof forming sheet clamped in the sheet fixing groove is guided to the sheet fixing groove from the upper lip surface, and then flows out into the bag to be discharged. become.

  At this time, in the present embodiment, the upper lip portion of the sheet fixing groove is formed with a plurality of convex portions that prevent the upper surface of the lip portion and the sheet from being in close contact with each other. Since adhesion to the surface can be prevented, condensation generated on the inner surface of the sheet can be reliably guided by the sheet fixing groove, and as a result, drainage performance is improved. In addition, this convex part may be the shape which raised the upper surface part of the upper lip part mechanically.

  Further, a concave condensed water introducing portion can be formed in the upper lip portion so as to face the opening of the sheet fixing groove, and the condensed water generated on the inner surface of the sheet is fixed to the sheet by the condensed water introducing portion. It becomes possible to guide smoothly by the groove. In addition, it is preferable to form this dew condensation water introducing | transducing part between the said convex part, and a shape dented mechanically from the edge part of the upper lip part to the width direction may be sufficient.

  In addition, since the valley anchor according to the present embodiment has a sheet fixing groove formed at the uppermost position of the side wall, the effective volume formed below the sheet fixing groove (the received water can be drained). The volume as a simple waterway) can be increased, and it is possible to cope with heavy rain.

  By the way, Motoya Satoshi is attached and fixed to a roof building pipe member of a vinyl house. In this embodiment, the shape of the sheet fixing groove formed at the top of the side wall is a vinyl sheet. Since it has the same shape as the rail-shaped sheet retainer used when fixing the sheet, no special dedicated fastener is required. That is, since a general-purpose fastener generally used for connecting and fixing the rail-shaped sheet fastener to a pipe member for building a house can be used as it is, the cost can be reduced, and a farmer who purchases the money can also make money. Burden is reduced.

  Hereinafter, embodiments of the present invention will be described more specifically with reference to the drawings. FIG. 1 is an explanatory view showing a state in which a trough is arranged according to the present embodiment, FIG. 2 is a front view of the trough, FIG. 3 is a front view showing a use state of the trough, and FIG. 4 and FIG. 6 is a partially enlarged explanatory view showing the use state, FIG. 6 is an explanatory view of a sheet fixing groove, and FIG. 7 is an explanatory view of an upper lip portion of the sheet fixing groove.

  As shown in FIG. 1, the trough A according to this embodiment is disposed in a trough 2 formed between adjacent vinyl houses 1 and 1 of a continuous-type vinyl house, and receives rainwater and the like. The drainage hole (not shown) provided at a necessary place of the valley ridge A, or a vertical culvert connected to the end portion, allows water to be introduced to the ground, and is disposed along the longitudinal direction of the house.

  The trough A is connected and fixed to the roof forming pipe member 10 among the pipe materials 10 and 11 for building a house shown in FIG.

  As shown in FIG. 2, the trough A is composed of a bottom wall 3 and left and right side walls 4, 4, and moves upward while gradually expanding the left and right side walls 4, 4 from the left and right edges of the bottom wall 3. It is stretched to form a bowl shape.

  The side wall 4 includes a lower side wall 4a extending upward from the bottom wall 3 at an angle of about 45 degrees, a middle wall 4b bent and extended so as to be raised about 20 degrees with respect to the lower side wall 4a, A sheet fixing groove 5 having a dovetail shape in cross section is formed at an upper position of the upper wall 4c. The upper wall 4c extends from the intermediate wall 4b substantially in parallel with the lower wall 4a. That is, the sheet fixing groove 5 is formed integrally with the side wall 4 at the uppermost part of the side wall 4.

  Thus, since the sheet fixing groove 5 is positioned at the uppermost portion of the side wall 4, the effective volume of water received below the sheet fixing groove 5 (the received water can be drained). The volume Q as a water channel) can be made relatively large, and it is possible to sufficiently cope with heavy rain.

  The sheet fixing groove 5 has the same shape as a rail-like general sheet binder used when fixing the vinyl sheet to the house building pipe material when the vinyl house 1 is constructed. A sheet receiving surface 50 formed and a groove opening 51 formed narrower than the sheet receiving surface 50 are provided.

  Then, as shown in FIG. 3, the roof forming sheet S can be fixed by being clamped by an elastic clamp member C in the sheet fixing groove 5. In FIG. 3, reference numeral 21 denotes a joint attached to the inner surface of the trough A with a predetermined interval. The trough pipe material 22 is inserted into the insertion hole 21 a formed in the joint 21, and A presser cord 23 is connected to the pipe material 22, and the sheet S is pressed against the pipe material 10 by the presser cord 23.

  Further, as described above, the sheet fixing groove 5 is formed at the uppermost part of the left and right side walls 4, 4, and the lower lip curved by bending the tip of the side wall 4 extending upward outward and downward once. The sheet receiving surface 50 is formed continuously with the lower lip portion 52, the leading end is bent inward continuously with the sheet receiving surface 50, and the leading end is folded back in a hairpin shape. A flat upper lip 53 is formed.

  The height h from the sheet receiving surface 50 of the upper lip portion 53 that forms the opening edge of the sheet fixing groove 5 is the lower lip portion that forms the opening edge and faces the upper lip portion 53. The height 52 is lower than the height H from the sheet receiving surface 50.

  As shown in FIG. 6, the upper lip portion 53 is formed with a plurality of convex portions 54 that prevent adhesion between the upper surface of the lip portion and the sheet S at appropriate intervals.

  The convex portion 54 may have a shape in which the upper surface portion 53a of the upper lip portion 53 is mechanically raised. In the present embodiment, the convex portion 54 has a mountain shape in which the opening edge side of the upper lip portion 53 is raised and gradually lowered to the opposite side. It is said.

  Further, a concave condensed water introduction portion 55 is formed between the adjacent convex portions 54 so as to face the groove opening 51. The condensed water introducing portion 55 may have a shape that is mechanically recessed in the width direction from the opening edge portion 53 b of the upper lip portion 53.

  With the above configuration, as shown in FIG. 4, when a windable sheet S <b> 1 that can be rolled up is suspended in the valley portion 2 of the adjacent vinyl house 1, the distance between the upper lip portion 53 and the sheet receiving surface 50 and the lower portion Since there is a difference d in the distance between the lip portion 52 and the seat receiving surface 50, the inner side surface in the vicinity of the skirt portion of the ventilation sheet S 1 is separated from the upper lip portion 53, while Therefore, the dew condensation B generated on the inner surface of the ventilation sheet S1 passes through the lower lip portion 52 and flows out into the valley A, or the lower lip portion 52. And the sheet fixing groove 5 is connected to the inside of the trough A, and the dew condensation water B1 can be reliably discharged. In FIG. 4, reference numeral 25 denotes a take-up pipe around which the tip of the bottom of the ventilation sheet S1 is wound.

  By the way, the ventilation sheet S1 is not clamped in the sheet fixing groove 5, but is merely wound around the winding pipe 25. By operating and rotating the rotating device or the like, an opening is formed in the valley and ventilation is possible, and the room temperature can be lowered by removing hot air or the like trapped above the vinyl house 1.

  On the other hand, the roof-forming sheet S located on the side of the end of the vinyl house 1 is clamped by a clamp material C in the sheet fixing groove 5 as shown in FIG. As shown in the figure, the condensation B generated on the inner surface of the roof forming sheet S is guided into the sheet fixing groove 5 from the surface of the upper lip portion 53, and then the sheet S is caused by the surface tension of the condensation B. The lower lip portion 52 is crossed over the back surface of the water and flows out into the valley A and is discharged.

  At this time, as shown in FIG. 7, the upper lip 53 is formed with the plurality of convex portions 54 described above, so that the sheet S does not adhere to the entire surface, and adjacent convex portions 54, 54. Since there is a gap between them, and the condensed water introduction part 55 is formed in this gap, the condensation B smoothly flows out from the condensed water introduction part 55 and enters the sheet fixing groove 5. .

  As described above, in the trough A according to the present embodiment, even if it is the sheet S for roof formation or the sheet S1 for ventilation that can be wound up, the dew condensation B that is generated inside these sheets is generated. Since the water can be efficiently guided to the inside of the valley A and drained to the ground outside the house, condensation does not drip into the inside of the vinyl house 1 to adversely affect crops and the like.

  Although the present invention has been described through the embodiments, the present invention is not limited to the above-described embodiments, and is included in the present invention unless departing from the gist of the present invention.
