Description

[Technical field]

[0001] The present invention relates to a sheet retaining member. [Background technology]

[0002] A conventional sheet holding member is, for example, one used to fix a sheet to the framework of a vinyl greenhouse. Specifically, the sheet holding member includes a bottom portion connected to the framework of the vinyl greenhouse, a side wall portion standing from one end of the bottom portion, and a sheet support portion standing from the other end of the bottom portion and having a U-shaped cross section with a screw groove opening toward the top end. Then, the sheet is placed on the sheet support portion, and with a pressing material placed on the sheet support portion, a screw is passed through the pressing material and the sheet and screwed into the screw groove of the sheet support portion to fix the sheet to the framework. (For example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-202054 A Summary of the Invention [Problem to be solved by the invention]

[0004] With conventional sheet holding members, when attaching the sheet holding member to the frame with screws, there was a risk of the screws creating holes that could allow condensation water to enter the greenhouse, making it difficult to adopt an attachment method using screws.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a sheet holding member that can prevent condensation water from entering a vinyl greenhouse even when attached with screws. [Means for solving the problem]

[0006] In order to achieve the above object, the sheet holding member of the present invention is characterized in that, in the sheet holding member for holding a sheet, it comprises a bottom, a side wall part rising from one end of the bottom, a sheet mounting part rising from the other end of the bottom, facing the side wall part and capable of mounting the sheet, and a partition part rising from between the one end and the other end of the bottom. With this configuration, even if the sheet holding member is arranged along the depth direction of the vinyl greenhouse and a screw is inserted into the bottom of the sheet holding member to connect the sheet holding member to the arch pipe of the vinyl greenhouse, the condensation water generated on the sheet and flowing down the sheet mounting part to the bottom is blocked by the partition part and accumulates between the partition part and the sheet mounting part. Therefore, since the condensation water does not accumulate between the partition part and the side wall part of the bottom, if a screw is inserted between the side wall part and the partition part of the bottom, the condensation water can be prevented from entering the vinyl greenhouse through the hole through which the screw is inserted. In the sheet holding member of the present invention, the sheet attachment portion can be attached to the tip end with the sheet spaced apart from the side wall portion.

[0007] In addition, in the sheet holding member of the present invention, the bottom portion has a first guide groove formed between the side wall portion and the partition portion and capable of guiding a screw, and a second guide groove formed between the sheet mounting portion and the partition portion and capable of guiding a screw. There are According to this configuration, when the sheet holding member is arranged along the depth direction of the vinyl greenhouse, by inserting a screw into the first guide groove, the sheet holding member can be easily fixed to the arch pipe while preventing condensation water from entering the vinyl greenhouse. On the other hand, when the sheet holding member is arranged along the arch pipe of the vinyl greenhouse, by inserting a screw into the second guide groove, the distance between the sheet mounting part where the sheet is attached and the part where the sheet holding member is fixed to the arch pipe becomes short, so that even if the sheet is blown by the wind, the force acting on the screw becomes small and the sheet holding member becomes less likely to come off the arch pipe. Effect of the Invention

[0008] According to the sheet holding member of the present invention, even when attached with screws, it is possible to prevent condensation water from entering the vinyl greenhouse. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The present embodiment will now be described with reference to the drawings, in which like reference numerals denote like parts throughout the several views.

[0011] 1 to 6, the sheet holding member 1 according to this embodiment has a cross-sectional shape including a bottom 2, a side wall 3 rising from one end of the bottom 2, a sheet attachment part 4 rising from the other end of the bottom 2 facing the side wall 3 and capable of attaching the sheets S1, S2, and a protrusion 6 protruding from the side wall 3 side of the sheet attachment part 4, and this cross-sectional shape forms a frame material that continues in the depth direction. This sheet holding member 1 can be cut to any length as needed for use, and in this embodiment, it is used when fixing the sheets S1, S2 of the vinyl greenhouse H.

[0012] As shown in Fig. 1, the vinyl greenhouse H is formed in a roughly kamaboko shape with multiple arch pipes P arranged in a line in the depth direction, multiple main pipes M bridged between the arch pipes P, and transparent sheets S1, S2 stretched across the arch pipes P and the main pipes M. Although multiple main pipes M are provided, they are not shown in the figure because they are provided on the back side of the sheet holding member 1.

[0013] The sheet holding member 1 according to this embodiment is, for example, as shown in Fig. 1, arranged along the arch pipe P on the gable side of the vinyl greenhouse H and is used to hold the sheets S1, S2 stretched on the gable side and the roof surface or side of the vinyl greenhouse H (for example, the part indicated by A in Fig. 1), or is arranged to span between adjacent arch pipes P, P and run along the depth direction of the vinyl greenhouse H and is used to hold the sheet S2 stretched on the roof surface side of the vinyl greenhouse H (for example, the part indicated by B in Fig. 1). Note that, although the sheet holding member 1 is attached to the arch pipe P in this embodiment, it may also be attached along the main house pipe M.

[0014] Next, each part of the sheet holding member 1 according to this embodiment will be described in detail below. The bottom 2 is flat and includes a partition wall 7 that stands vertically from the center of the left and right in Fig. 2 and continues along the depth direction of the bottom 2. The partition wall 7 does not have to be provided in the center of the bottom 2, and may stand at an angle to the bottom 2. Furthermore, guide grooves 2a and 2b are formed along the depth direction on both sides of the partition wall 7 of the bottom 2.

[0015] As shown in Figure 2, the side wall portion 3 has a curved portion 3a that bulges from one end (the right end in the figure) of the bottom portion 2 in the width direction, which is the left-right direction in the figure, toward the side opposite the seat mounting portion, and a slip-out prevention portion 3b that inclines from the upper end of the curved portion 3a toward the seat mounting portion 4 side.

[0016] 2, the seat attachment portion 4 includes a base portion 4a that stands upward in the figure from the other end (the left end in the figure) in the width direction of the bottom portion 2, and a pair of left and right support portions 4b, 4b in the figure that extend in two branches from the upper end of the base portion 4a, and a screw groove 5 is formed on the inner surfaces of the support portions 4b that face each other. Also, a seat receiving portion 4c that protrudes outward is provided at the upper end of each support portion 4b.

[0017] Furthermore, the seat mounting portion 4 has a protruding portion 4d extending from the side opposite the side wall portion at the lower end of the seat mounting portion 4 in Fig. 2. Also, as shown in Fig. 2, a recessed portion 4e is formed between the protruding portion 4d and the bottom portion 2. This allows the amount of material of the seat holding member 1 to be reduced by the amount of the recessed portion 4e.

[0018] 2, a protrusion 6 that protrudes toward the side wall 3 is provided on the side wall 3 side of the support portion 4b that is disposed on the side wall 3 side (right side in the figure) of the seat attachment portion 4. The upper surface in FIG. 2, which is the side opposite to the bottom, of this protrusion 6 is inclined toward the bottom 2 side, and the lower surface in FIG. 2, which is the side facing the bottom 2, of the protrusion 6 is parallel to the bottom 2.

[0019] Next, the methods of using the sheet holding member 1 will be explained in two ways: when the sheet holding member 1 is arranged along the arch pipe P and used to hold the sheets S1, S2 stretched over the gable side and the roof or side of the vinyl greenhouse H, and when the sheet holding member 1 is arranged so as to span between adjacent arch pipes P, P along the depth direction of the vinyl greenhouse H and used to hold the sheet S2 stretched over the roof side of the vinyl greenhouse H.

[0020] When the sheet holding member 1 is used by arranging it along the arch pipe P, first, as shown in FIG. 3, the sheet holding member 1 is arranged along the arch pipe P with the sheet mounting part 4 facing the gable side of the vinyl greenhouse H, and the second guide groove 2b formed between the sheet mounting part 4 of the bottom part 2 and the partition part 7 is arranged so as to face the arch pipe P. After that, the tip of the screw 10 is inserted into the second guide groove 2b, and the screw 10 is pressed against the bottom part 2 and screwed in, so that the screw 10 penetrates the bottom part 2 and the arch pipe P, and the sheet holding member 1 is fixed to the arch pipe P. Note that the fixing by the screw 10 is performed at multiple points at intervals in the depth direction of the bottom part 2.

[0021] Next, as shown in FIG. 3, one end of the sheet S1 on the gable side of the vinyl greenhouse H is placed over the sheet holding member 1, and the other end of the sheet S1 is made to hang down on the gable side of the vinyl greenhouse H.

[0022] Then, from above the sheet S1 placed over the sheet holding member 1, the right end of the elastic member 11, which is a wavy spring, in FIG. 3 is placed in the space between the bottom 2 and the anti-slip portion 3b, and the elastic member 11 is pressed toward the bottom 2 while contracting, so that the elastic member 11 is attached between the underside of the protrusion 6 and the curved portion 3a, which is the lower end of the side wall portion 3.

[0023] Then, the sheet S1 on the end surface side is temporarily fixed to the sheet holding member 1 by the elastic force of the elastic member 11 while being placed on the sheet receiving portion 4c formed on the upper end of the sheet attachment portion 4.

[0024] Here, the partition 7 is set to a height such that the upper end abuts against the elastic member 11 when the elastic member 11 is attached between the protrusion 6 and the curved portion 3a. Therefore, as shown in FIG. 3, when the elastic member 11 is attached between the protrusion 6 and the curved portion 3a, the tip of the partition 7 abuts against the elastic member 11 via the sheet S1 to support the elastic member 11. As a result, the elastic member 11 is positioned by the partition 7 when attached, so that the elastic member 11 can be easily attached. In addition, the partition 7 also functions as a stopper that prevents the elastic member 11 from entering too far into the bottom 2 side, so there is no risk that the elastic member 11 will be attached to the sheet holding member 1 in an unstable position in which it enters too far into the bottom 2 side and is separated from the protrusion 6. Therefore, the sheet holding member 1 can stably hold the sheet S1. However, the partition 7 may be set to any height as long as it does not interfere with the elastic member 11 attached between the protrusion 6 and the curved portion 3a.

[0025] In this embodiment, a wave spring is used as the elastic member 11, but for example, rubber or a coil spring may be used. As shown in Fig. 3, the side wall 3 has a retaining portion 3b that is inclined toward the seat mounting portion 4, so that the elastic member 11 attached between the protrusion 6 and the curved portion 3a is retained by the protrusion 6 and the side wall 3, and the elastic member 11 is prevented from falling off. In the figure, the retaining portion 3b is inclined at an angle of about 45 degrees with respect to the bottom 2, but the inclination angle of the retaining portion 3b is not particularly limited as long as it functions as a retaining portion for the elastic member 11.

[0026] Then, as shown in Figures 4 and 5, the sheet S2 on the roof or side of the vinyl greenhouse H is placed on the sheet S1 on the gable side and placed on the sheet receiving portion 4c of the sheet mounting portion 4. A pressure member 12 with a U-shaped cross section is then placed over the sheet receiving portion 4c, and a screw 13 is passed through the pressure member 12 and each sheet S1, S2 and screwed into the thread groove 5 formed on the inner surface of the support portions 4b, 4b. In this case, as shown in FIG. 4, the pressing material 12 in this embodiment has a flat plate portion 12a facing the sheet receiving portion 4c via the sheets S1, S2, legs 12b, 12b provided at both ends of the flat plate portion 12a facing each other, and a protrusion 12c standing vertically between the legs 12b, 12b of the flat plate portion 12a, and when the legs 12b and the protrusions 12c press down the sheet S2 on the roof surface side or side surface side, the sheet S2 is pressed between the support portions 4b, 4b and against both sides of the support portions 4b, 4b, and tension is applied to the sheet S2. As a result, the sheet S2 does not wrinkle and can be stretched out in a taut state over the vinyl greenhouse H.

[0027] Furthermore, since the elastic member 11 is attached between the protrusion 6 and the curved portion 3a, when the pressing member 12 is placed over the sheet receiving portion 4c, the protrusion 6 prevents the elastic member 11 from floating up, so that the leg portions 12b of the pressing member 12 do not interfere with the elastic member 11, and the sheets S1, S2 can be easily attached to the sheet mounting portion 4.

[0028] In this manner, the sheet holding member 1 can hold the sheets S1, S2 stretched over the gable surface side and the roof surface side or side surface side of the vinyl greenhouse H, as shown in Figs.

[0029] 3 to 5, the sheet holding member 1 is connected to the arch pipe P by the screw 10, but as shown in Fig. 6, a connecting fitting 15 may be used instead of the screw 10. Specifically, as shown in Fig. 6, the connecting fitting 15 has a flat bottom plate 15a, a pair of hook-shaped hanging portions 15b, 15b protruding upward from both the left and right ends of the bottom plate 15a in the figure, a pair of vertical pieces 15c, 15c extending vertically downward from both the left and right ends of the bottom plate 15a in the figure and facing each other, and wedge holes 15d, 15d provided below each vertical piece 15c and facing each other. Then, by hooking each hook portion 15b to the protruding portion 4d and the side wall portion 3 of the sheet holding member 1, respectively, and inserting a wedge K into the wedge hole 15d provided in each vertical piece 15c with the arch pipe P disposed between the vertical pieces 15c, 15c, the arch pipe P is clamped between the bottom plate 15a and the wedge K, and the connecting fitting 15 fixes the sheet holding member 1 to the arch pipe P. At this time, since the wedge K can be inserted into the wedge hole 15d from a direction intersecting the arch pipe P, the arch pipe P does not get in the way when inserting the wedge K, and the wedge K can be easily inserted into the wedge hole 15d compared to inserting the wedge K from a direction along the arch pipe P. The configuration of the connecting fitting 15 is not limited to the above-mentioned configuration, and may be any configuration that can fix the sheet holding member 1 to the arch pipe P.

[0030] When the sheet holding member 1 is connected to the arch pipe P with the connecting metal fittings 15 in this way, the connection strength is superior to that of the case of connection with the screws 10. However, connection with the screws 10 is easier to install than connection with the connecting metal fittings 15, and the screws 10 are less expensive than the connecting metal fittings 15, so it is excellent in workability and economy. Therefore, connection with the connecting metal fittings 15 and connection with the screws 10 may be performed alternately. In this way, it is possible to ensure the connection strength while improving the workability and economy of the installation. Note that when the sheet holding member 1 is fixed to the arch pipe P with only the screws 10, the sheet holding member 1 may be formed without the protruding portion 4d, in which case the material can be reduced.

[0031] Next, a case where the sheet holding member 1 is placed between adjacent arch pipes P, P along the depth direction of the vinyl greenhouse H will be described. First, as shown in FIG. 7, the sheet holding member 1 is placed between the arch pipes P, P in a direction in which the side wall portion 3 is placed on the ridge side of the vinyl greenhouse H. Then, the tip of the screw 14 is inserted into the first guide groove 2a formed between the side wall portion 3 and the partition wall portion 7 of the bottom portion 2 facing the arch pipe P, and the screw 14 is pressed against the bottom portion 2 and screwed in, so that the screw 14 penetrates the bottom portion 2 and the arch pipe P, and the sheet holding member 1 is fixed to the arch pipe P. The fixing by the screw 14 is performed at each location of the bottom portion 2 facing the arch pipe P.

[0032] Next, with the sheet S2 on the roof surface side of the vinyl greenhouse H placed on the sheet receiving portion 4c of the sheet mounting portion 4, the pressing member 12 is placed over the sheet receiving portion 4c, and the screws 13 are passed through the pressing member 12 and the sheet S2 and screwed into the thread grooves 5 formed on the inner surfaces of the support portions 4b, 4b. Even in this case, the legs 12b and protrusions 12c of the pressing member 12 press down the sheet S2, so that the sheet S2 is pressed between the support portions 4b, 4b and against both sides of the support portions 4b, 4b, and tension is applied to the sheet S2, so that the sheet S2 does not wrinkle and can be spread out in a taut state over the vinyl greenhouse H.

[0033] In this way, the sheet holding member 1 can hold the sheet S2 stretched on the roof surface side of the vinyl greenhouse H, as shown in FIG. 7. Furthermore, as shown in FIG. 7, the sheet holding member 1 stretched between the arch pipes P, P is inclined along the arch pipe P so that the side wall portion 3 is disposed on the upper side and the sheet mounting portion 4 is disposed on the lower side, and even if condensation water occurs on the side of the vinyl greenhouse H, which is located on the upper left side of the sheet S2 in FIG. 6, rather than the sheet holding member 1, this condensation water flows down the sheet S2 from the upper side to the lower side, and flows down the sheet mounting portion 4 to which the sheet S2 is attached via the pressing member 12, and accumulates between the partition portion 7 of the bottom portion 2 and the sheet mounting portion 4. Therefore, condensation water does not accumulate between the partition portion 7 of the bottom portion 2 and the side wall portion 3, which is opened by the screw 14, and therefore it is possible to prevent the condensation water from entering the vinyl greenhouse H through the hole formed by the screw 14 between the partition portion 7 of the bottom portion 2 and the side wall portion 3. In this embodiment, the sheets S1 and S2 stretched over the vinyl greenhouse H are all hard sheets, but they may be soft sheets.

[0034] In the embodiment shown in Fig. 7, the sheet retaining member 1 is connected to the arch pipe P by the screw 14, but as shown in Fig. 8, a connecting metal fitting 16 may be used instead of the screw 14. Specifically, the connecting metal fitting 16 has a pair of U-shaped pieces 16a, 16a facing each other, connecting pieces 16b, 16b that are bridged between the facing tips of each of the U-shaped pieces 16a, 16a, claw portions 16c that protrude inward from each of the connecting pieces 16b, and wedge holes 16d that are provided below each of the U-shaped pieces 16a, 16a and facing each other. Then, by hooking each claw portion 16c onto the protruding portion 4d and the side wall portion 3 of the sheet holding member 1, respectively, and inserting the wedge 17 into the wedge hole 16d with the arch pipe P disposed between the U-shaped pieces 16a, 16a, the arch pipe P is clamped by the claw portion 16c and the wedge 17, and the connecting fitting 16 fixes the sheet holding member 1 to the arch pipe P. At this time, since the wedge 17 can be inserted into the wedge hole 16d from a direction intersecting the arch pipe P, the arch pipe P does not get in the way when inserting the wedge 17, and the wedge 17 can be easily inserted into the wedge hole 16d compared to inserting the wedge 17 from a direction along the arch pipe P. The configuration of the connecting fitting 16 is not limited to the above-mentioned configuration, and may be any configuration that can fix the sheet holding member 1 to the arch pipe P.

[0035] When the sheet holding member 1 is connected to the arch pipe P by the connecting metal fittings 16 in this way, the connection strength is superior to that when the sheet holding member 1 is connected to the arch pipe P by the screws 14. In addition, when the sheet holding member 1 is connected to the arch pipe P by the connecting metal fittings 16, there is no need to drill holes in the bottom 2, so there is no risk of condensation water entering the vinyl greenhouse H through the holes in the bottom 2. However, the connection by the screws 14 is easier to install than the connection by the connecting metal fittings 16, and the screws 14 are less expensive than the connecting metal fittings 16, so that the workability and economy are excellent. Therefore, the connection by the connecting metal fittings 16 and the connection by the screws 14 may be alternated. In this way, the connection strength can be secured while improving the workability and economy of the installation. When the sheet holding member 1 is fixed to the arch pipe only by the screws 14, the sheet holding member 1 may be formed without the protruding portion 4d, in which case the material can be reduced.

[0036] In addition, in this embodiment, the arch pipe P is formed of a round pipe, but it may be formed of a square pipe. Alternatively, when a reinforcing H-beam is provided along the arch pipe P, the sheet retaining member 1 may be connected to the H-beam.

[0037] As described above, the sheet holding member 1 in this embodiment comprises a bottom 2, a side wall portion 3 rising from one end of the bottom 2, a sheet mounting portion 4 rising from the other end of the bottom 2 and facing the side wall portion 3 and capable of mounting the sheets S1, S2, and a protrusion 6 protruding from the side wall portion 3 side of the sheet mounting portion 4 and capable of attaching an elastic member 11 between the sheet mounting portion 4 and the lower end of the side wall portion 3.

[0038] According to this configuration, when the sheet S1 is temporarily fixed with the elastic member 11, the elastic member 11 is attached between the protrusion 6 and the curved portion 3a formed at the lower end of the side wall portion 3. As a result, when the pressing member 12 is placed over the sheet mounting portion 4, the pressing member 12 does not interfere with the elastic member 11 and float up, and the sheets S1, S2 can be easily fixed to the sheet mounting portion 4, improving the ease of mounting the sheets S1, S2. Note that, as shown in the figure, the shape of the protrusion 6 may be any shape that prevents the elastic member from falling off, and the design can be modified as appropriate.

[0039] Moreover, in the sheet holding member 1 according to this embodiment, the side wall 3 has a stopper portion 3b at its tip which is inclined toward the sheet attachment portion 4. With this configuration, when the elastic member 11 is attached between the lower end of the side wall 3 and the protrusion 6, the elastic member 11 is prevented from falling off by the stopper portion 3b of the side wall 3, so that the attached elastic member 11 can be prevented from falling off.

[0040] Moreover, the sheet holding member 1 according to this embodiment has a partition wall portion 7 standing up from between one end and the other end of the bottom portion 2. With this configuration, even if the sheet holding member 1 is arranged along the depth direction of the vinyl greenhouse H and the screw 14 is inserted into the bottom portion 2 of the sheet holding member 1 to connect the sheet holding member 1 to the arch pipe P of the vinyl greenhouse H, the condensation water flowing from the sheet S2 along the sheet mounting portion 4 to the bottom portion 2 is blocked by the partition wall portion 7 and accumulates between the partition wall portion 7 and the sheet mounting portion 4. Therefore, since the condensation water does not accumulate between the partition wall portion 7 of the bottom portion 2 and the side wall portion 3, if the screw 14 is inserted between the side wall portion 3 of the bottom portion 2 and the partition wall portion 7, the condensation water can be prevented from entering the vinyl greenhouse H through the hole formed by the insertion of the screw 14.

[0041] In other words, compared to mounting means that do not drill holes in the bottom 2, such as the connecting fittings 16, when mounting the sheet holding member 1 to the arch pipe P with screws 14, there was a risk that holes would be opened by the screws 14 and condensation water would enter the vinyl greenhouse H, making it difficult to adopt a mounting means using screws 14. However, by providing the partition section 7, it is possible to prevent condensation water from entering the vinyl greenhouse H, making it possible to adopt a mounting means using screws 14.

[0042] Therefore, according to the above configuration, when the sheet holding member 1 is positioned along the depth direction of the vinyl greenhouse H, the sheet holding member 1 can be connected to the arch pipe P of the vinyl greenhouse H with the screws 14 without using the connecting fittings 16 and without having to worry about condensation water entering the vinyl greenhouse H.

[0043] However, the partition wall 7 may be omitted when the sheet holding member 1 is only used when arranged along the arch pipe P. When the sheet holding member 1 is arranged along the arch pipe P, the sheet holding member 1 is inclined along the shape of the arch pipe P in the depth direction of the bottom 2, so that even if condensation water generated on the sheet S2 gets onto the bottom 2 of the sheet holding member 1, the condensation water flows over the bottom 2 and is drained outside the vinyl greenhouse H.

[0044] Alternatively, even if the sheet holding member 1 is disposed in the depth direction of the vinyl greenhouse H, if it is connected to the arch pipe P using the connecting metal fitting 16, the partition portion 7 can be omitted.

[0045] In addition, in the sheet holding member 1 according to the present embodiment, the partition 7 supports the elastic member 11 that is attached between the protrusion 6 and the lower end of the side wall 3. With this configuration, the elastic member 11 is positioned by the partition 7 when the elastic member 11 is attached, making it easier to attach the elastic member 11. The partition 7 may be set to any height as long as it does not interfere with the attachment of the elastic member 11, but the higher the partition 7, the greater the amount of water that can be blocked. Therefore, if the partition 7 is set to a height that supports the elastic member 11 that is attached between the protrusion 6 and the lower end of the side wall 3, the elastic member 11 can be supported, and the amount of water that can be blocked can be maximized without interfering with the attachment of the elastic member 11.

[0046] In addition, the bottom 2 of the sheet holding member 1 according to the present embodiment has a first guide groove 2a formed between the side wall portion 3 and the partition portion 7 and capable of guiding the screw 14, and a second guide groove 2b formed between the sheet mounting portion 4 and the partition portion 7 and capable of guiding the screw 10. According to this configuration, when the sheet holding member 1 is arranged so as to be along the depth direction of the vinyl greenhouse H, the sheet holding member 1 can be easily fixed to the arch pipe P by inserting the screw 14 into the first guide groove 2a, while preventing condensation water from entering the vinyl greenhouse H. Also, when the sheet holding member 1 is arranged so as to be along the arch pipe P, the distance between the sheet mounting portion 4, which is the portion where the sheets S1 and S2 are fixed, and the portion where the sheet holding member 1 is fixed to the arch pipe P is shortened by inserting the screw 10 into the second guide groove 2b, so that even if the sheets S1 and S2 are blown by the wind, the force acting on the screw 10 is reduced, and the sheet holding member 1 is less likely to come off the arch pipe P. In addition, the bottom 2 is provided with guide grooves 2a, 2b capable of guiding the screws 10, 14, making it possible to easily insert the screws 10, 14. However, since the screws 10, 14 can be inserted without providing the guide grooves 2a, 2b, the guide grooves 2a, 2b may be omitted.

[0047] Although the preferred embodiment of the present invention has been described in detail above, it is natural that the present invention can be modified, changed, and altered without departing from the scope of the claims. For example, in this embodiment, the sheet holding member 1 is used in a vinyl greenhouse H, but the use is not limited to vinyl greenhouses as long as the sheet is stretched.
