Description

Technical Field

[0001] The present invention relates to a technique for externally installing a curtain on the roof of a building. In particular, it relates to a spacer for a curtain that secures a gap between the roof of a building and the curtain externally installed thereon, a curtain gap holding device using the same, and an installation method thereof.

Background Art

[0002] Cultivation houses covered with vinyl or glass are equipped with curtains such as insect nets and shading curtains in order to protect crops from direct sunlight and external air temperatures that are too high or too low. Although the insect nets and shading curtains can block sunlight when installed inside or outside the roof of the cultivation house, they have the drawback of being easily affected by the external air temperature transmitted through the vinyl or glass of the roof.

[0003] Also, when the insect nets or shading curtains are externally installed in close contact on the vinyl or glass of the roof, they can appropriately block direct sunlight. However, they have the drawback that heat from the sun, heat from the external air, or cold caused by the external air is transmitted into the cultivation house through the vinyl or glass of the roof from the insect nets or shading curtains, which has an adverse effect on the crops.

[0004] As a technique for solving the above drawbacks, for example, in Patent Document 1 (Japanese Utility Model Publication No. 50-151758), in a cultivation house composed of a transparent film or glass, at least on the upper side of the roof, a support frame or the like for stretching a shading curtain such as an insect net is provided, so that a ventilation space is separated between the upper side of the roof and the shading curtain. While blocking sunlight with the shading curtain, heat absorbed by the shading curtain due to shading can be dissipated to the air flowing through the ventilation space. A cultivation house is shown.

[0005] Also, in Patent Document 2 (Japanese Utility Model Publication No. 52-25940), a plurality of insect nets are arranged at appropriate intervals in the front-rear direction in the upper space of the planting area and stretched in an inclined state facing upward. There is shown a structure for stretching an insect net that protects the insect net from the load of rain and snow and allows ventilation through the appropriate interval.

[0006] [Patent Document 1] Japanese Utility Model Publication No. 50-151758 [Patent Document 2] Japanese Utility Model Publication No. 52-25940 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] However, as mentioned above, the cultivation greenhouse shown in Patent Document 1 has the support frames and pulleys installed on the framework of the main pipes of the cultivation greenhouse, which increases the installation time and cost. Furthermore, since the support frames and pulleys are mounted, the strings of the shading curtain are wrapped around the pulleys, and the curtain is opened and closed by turning a handle, a significant load is placed on the cultivation greenhouse.

[0008] The cheesecloth stretching structure described in Patent Document 2 does not require a vinyl or glass cultivation greenhouse, but if it were to be used as an exterior for a cultivation greenhouse, it would require multiple support posts, pulleys, circulation cables and support cables, which would increase the installation time and cost.

[0009] In view of these circumstances, the present invention provides a spacer for a curtain, a curtain spacing retention device utilizing the same, and a method for installing the same, which can form a gap between the roof of a building and the covering curtain (for example, shade cloth or shading curtain) that is applied to the exterior of the roof, thereby reducing the load on the building and reducing the installation time and cost. [Means for solving the problem]

[0010] The present invention provides a curtain spacer comprising: a long main frame with a smooth curtain support at the top; support legs suspended from at least both ends of the main frame in the longitudinal direction and having a smooth ground surface that ensures a support width to prevent overturning in both the horizontal direction intersecting the longitudinal direction of the main frame; and connecting parts provided at both ends of the main frame in the longitudinal direction, or at least one of the pair of support legs positioned at both ends of the main frame in the longitudinal direction, wherein the height from the ground surface to the top is set to the curtain support height.

[0011] The curtain spacer, when interposed between the roof of a building and the covering curtain installed on the roof, secures a space between the roof and the covering curtain equal to the height of the curtain support, preventing heat transfer to the roof due to the covering curtain's close contact. The curtain spacer allows air to be retained and ventilated between the roof and the covering curtain, improving heat insulation, heat retention, and heat dissipation. The roof of such a building may be a roof of a wooden or steel-framed building such as an ordinary house, or a roof of a cultivation greenhouse covered with vinyl or glass, i.e., a roof made of vinyl sheeting or glass panels.

[0012] The main frame stably supports the covering curtain by the smooth curtain support portion without placing an excessive load on the covering curtain. The main frame can be in the shape of a long rod or a long rod with a smoothly raised section in the middle, and can be formed into shapes such as a straight rod, a curved rod, a flat plate, or a curved plate. When the main frame is positioned with its long direction facing the direction of the roof's slope, its length can be set so that it does not tip over due to the slope of the roof, and the length of the main frame in the long direction can be set to be longer than the curtain support height. The curtain support height can be, for example, 100 cm or less. If the curtain support height exceeds 100 cm, the gap between the roof and the covering curtain becomes too large, making it difficult to ensure heat retention and insulation.

[0013] The curtain support section is formed to support the covering curtain with uniform load distribution. Such a curtain support section can be shaped like an inverted boat bottom, an inverted skid plate, a rugby ball, or the like. The curtain support section is rotatably supported along the top of the main frame and is equipped with at least one cylindrical, spherical, or elongated spherical pulley, which can rotatably support the covering curtain with slidable load distribution.

[0014] The support legs support the main frame at the curtain support height. The support legs are formed to have a sufficient support width to prevent the main frame from tipping over and to stably support it, so as to prevent it from tipping over in both the longitudinal direction and the horizontal direction intersecting the longitudinal direction, and to have a smooth contact surface that does not put a load on the roof. It is desirable that the support legs be formed so as to support the main frame directly above a point half the distance from both ends of the support legs. By setting the weight of one support leg to be equal to or heavier than the weight of one main frame, the center of gravity of the curtain spacer can be lowered, and the installation stability can be increased. Furthermore, by forming the support legs so that the center of gravity is closer to the contact surface in the direction of the curtain support height, the center of gravity of the curtain spacer can be lowered, and the stability during installation can be increased.

[0015] The support width of the support legs is a width dimension that prevents the curtain spacer from tipping over, and is a width dimension that prevents tipping in both horizontal directions that intersect the longitudinal direction of the main frame. The support width can be set to be longer than the curtain support height. The support width can be the sum of dimensions equal in both horizontal (left and right) directions that intersect the longitudinal direction of the main frame.

[0016] The aforementioned contact surface is preferably designed to increase the contact area of ​​the support legs with the roof and distribute the load. By making the contact surface a smooth surface, it is possible to move smoothly over the roof, and in particular, if the roof is made of vinyl sheeting, the load on the roof can be reduced. Furthermore, by making the contact surface a flat surface and making the edges of both ends in the longitudinal direction of the main frame curved smooth surfaces, the risk of damage to the vinyl sheeting roofing material can be eliminated.

[0017] The connecting portion is formed in a shape and structure that allows tensioning harnesses and other cables to be connected to the curtain spacer. The connecting portion can be a ring, hook, or other connecting fitting that has sufficient strength to secure the curtain spacer.

[0018] The curtain support height is the height of the gap that the curtain spacer secures between the roof and the covering curtain, and it is desirable that the height be such that the covering curtain does not come into direct contact with the roof and a sufficient air layer or airflow is secured between the roof and the covering curtain.

[0019] Furthermore, in order to solve the above-mentioned problems, the present invention provides a curtain spacer in which the support leg is set to a dimension that exceeds the distance between two adjacent installations in the ridge direction of the roof structure of the building, with respect to the support width of the contact surface.

[0020] The aforementioned curtain spacer can be mounted horizontally on two or more adjacent pipes in the ridge direction of the roof's structural framework in the direction of the roof's flow, thus allowing it to be installed without placing a load on the roofing material. Furthermore, the curtain spacer can be mounted horizontally on two or more adjacent pipes in the ridge direction of the roof's flow in a building constructed by covering support columns made of steel pipes or the like with a vinyl sheet (hereinafter also referred to as a "vinyl greenhouse"), thus allowing it to be installed without placing a load on the vinyl sheet stretched over the vinyl greenhouse. The aforementioned curtain spacer can be mounted horizontally on two or more adjacent frames in the ridge direction of the roof's flow in a building constructed of a metal frame and glass panels (hereinafter also referred to as a "glass house"), thus allowing it to be installed without placing a load on the glass of the glass house.

[0021] The spacing of the curtain spacers can be the same as the spacing between two or more adjacent frames in the ridge direction of the roof's flow direction, and the support width of the ground surface can be the same as the spacing between two adjacent frames in the ridge direction of the frame, plus a margin to compensate for shearing movement. The roof's flow direction frame of the building can be replaced, for example, with the flow direction pipes of a greenhouse roof or the flow direction frame of a glasshouse roof. The support width of the ground surface can be set shorter than the longitudinal length of the main frame.

[0022] The curtain spacer can be set to have a tipping angle of 45° or more at the installation location if at least one of the following dimensional ratios is set to 1:1 or more: the ratio of the curtain support height to the length of the main frame, the ratio of the curtain support height to the support width, and the ratio of the support width to the length of the main frame. Setting at least one of the following dimensional ratios to 1:1 or more is the golden ratio (5:8), the second precious metal ratio (5:12), the Yamato ratio (5:7), the bronze ratio (3:9), the platinum ratio (4:7), the second golden ratio (3:8), etc., which enhances the tipping prevention effect at the installation location and presents an appearance with superior aesthetic balance and stability.

[0023] Furthermore, in order to solve the above problems, the present invention provides a curtain spacing holding device that utilizes a curtain spacer as described above, comprising: a curtain spacer whose top portion of the main frame is curved to conform to the shape of the building's roof; a pair of tensioning harnesses connected to the respective connecting portions of the curtain spacer; and a length adjustment mechanism provided on the tensioning harness.

[0024] According to the curtain interval maintaining device, the curtain spacer can be temporarily fixed at a desired position on the roof of the building. Since the top part of the main frame is curved following the shape of the roof of the building, when installed on a roof whose shape changes in the flow direction, such as an arch pipe of a greenhouse, a certain curtain support height can be ensured along the flow direction. The pair of stretching harnesses are stretched in a direction intersecting the ridge direction of the building and can temporarily fix the curtain spacer. The stretching harness enables adjustment of the arrangement of the curtain spacer with respect to the roof of the building and enables temporary fixing of the curtain spacer to the roof. The length adjustment mechanism can adjust the length of the stretching harness, adjust the arrangement of the curtain spacer, and can be temporarily fixed in the stretched state. The length adjustment mechanism can be a tightening mechanism.

[0025] The curtain interval maintaining device can be a curtain interval maintaining device using the curtain spacer according to any of the above, which includes a plurality of the curtain spacers arranged in series at intervals, a connecting harness connecting the opposing connecting parts of the plurality of curtain spacers, a pair of stretching harnesses respectively connected to the connecting parts arranged at both ends of the plurality of curtain spacers arranged in series, and a length adjustment mechanism provided on the stretching harness.

[0026] According to such a curtain interval maintaining device, since a plurality of the curtain spacers can be mounted continuously along the flow direction on the roof of the building, a gap that is continuous along the flow direction can be created between the roof and the covering curtain, and the ventilation can be further enhanced. The connecting harness can have the same or equivalent physical properties as the stretching harness. The connecting harness can have, for example, a length adjustment mechanism.

[0027] The method for installing the curtain spacing device comprises: an installation step of arranging the curtain spacers along one flow direction on either side of the ridge of the building's roof, connecting each of the pair of tensioning harnesses to the corresponding side beams on either side of the ridge of the roof, and installing the curtain spacing device; an adjacent installation step of arranging an adjacent curtain spacer at a position adjacent to the curtain spacing device installed in the installation step in the direction of the ridge, along the other flow direction on either side of the ridge of the roof, connecting each of the pair of tensioning harnesses of the adjacent curtain spacer to the corresponding side beams on either side of the ridge of the roof, and installing the adjacent curtain spacing device; and a covering step of covering the curtain spacers with a covering curtain after performing the adjacent installation step at least once.

[0028] According to this method of installing the curtain spacing device, multiple curtain spacing devices can be installed in the direction of the ridge of the building's roof. According to this method of installing the curtain spacing device, one of the curtain spacers of two adjacent curtain spacing devices in the direction of the ridge is positioned along one flow direction on either side of the ridge, and the other curtain spacer is positioned along the other flow direction on either side of the ridge, thereby ensuring a more uniform air layer and ventilation throughout the entire space between the roof and the covering curtain.

[0029] The installation step of the curtain spacing device is a step of placing one curtain spacer on the roof of the building and installing the curtain spacing device, and the adjacent installation step is a step of placing another curtain spacer adjacent to the curtain spacer and installing adjacent curtain spacing devices. By repeating the adjacent installation step, a plurality of curtain spacing devices can be installed in an adjacent arrangement in the ridge direction of the roof. The covering step is to cover the installed curtain spacers with a covering curtain, thereby creating a gap between the roof and the covering curtain at each installation location of the curtain spacer that corresponds to the curtain support height of the curtain spacer.

[0030] Furthermore, in order to solve the above problems, the present invention provides a method for installing a curtain spacing device, comprising: an installation step of installing the curtain spacing device by arranging at least one of the plurality of curtain spacers along one flow direction on either side of the ridge of the building's roof, hanging the middle portion of one of the connecting harnesses over the ridge, arranging the remaining curtain spacers along the other flow direction on either side of the ridge, and connecting each of the pair of tensioning harnesses to the corresponding side beams on either side of the ridge of the roof; an adjacent installation step of installing an adjacent curtain spacing device next to the curtain spacing device by the same process as the installation step; and a covering step of covering the curtain spacers with a covering curtain after performing the adjacent installation step at least once.

[0031] According to the method for installing the curtain spacing device described above, the curtain spacers can be arranged along both slope directions on either side of the roof ridge, and furthermore, multiple curtain spacing devices can be installed adjacent to each other in the ridge direction.

[0032] The installation step is to install the curtain spacing holding device, which has at least one curtain spacer along each of the two flow directions on either side of the roof ridge, and the adjacent installation step is to install the adjacent curtain spacing holding device, which has the same structure as the curtain spacing holding device, next to the curtain spacing holding device in the direction of the roof ridge. By repeating the adjacent installation step, a plurality of curtain spacing holding devices can be installed in an adjacent arrangement in the direction of the roof ridge. The covering step is to cover the installed curtain spacers with a covering curtain, thereby creating a gap between the roof and the covering curtain at each installation location of the curtain spacer, corresponding to the curtain support height of the curtain spacer, continuously along the two flow directions on either side of the roof ridge. [Effects of the Invention]

[0033] According to the curtain spacer, curtain spacing retention device utilizing the same, and installation method thereof, a gap that allows for air retention and flow can be formed between the roof of a building and the covering curtain covering the roof. This eliminates the need to mount a skeletal frame or the like on the building, thus reducing the load. Furthermore, it offers the excellent effect of reducing installation time and costs by reducing the number and weight of parts. [Brief explanation of the drawing]

[Figure 5] Plan view showing parallel-arranged curtain spacing devices 1 and 10, and series-arranged curtain spacing device 11. [Modes for carrying out the invention]

[0035] (Spacer for curtains) The curtain spacer according to this embodiment will be described in detail below with reference to the drawings. In particular, this embodiment has a long main frame 3 with a length of 31, the top portion 30 of which is a smooth curtain support portion 30; support legs 4 that are vertically attached to at least both ends of the main frame 3 in the longitudinal direction and have a smooth ground surface 40 that secures a support width 41 in both the horizontal direction intersecting the longitudinal direction of the main frame 3 to prevent overturning; and connecting portions 5 provided at both ends of the main frame 3 in the longitudinal direction, or at least one of the pair of support legs 4 that are placed at both ends of the main frame 3 in the longitudinal direction, and the height from the ground surface 40 to the top portion 30 is set to the curtain support height 7.

[0036] As shown in Figures 1 to 3, the top portion 30 of the main frame 3 is curved or bent upward, following the shape of the arch pipe 81, which is the flow-direction framework 81 of the roof 80 of a building 8, such as a vinyl greenhouse 8. The main frame 3 can be formed from, for example, metal pipes or rods, or it can be formed as a long member using wood, resin, or other materials. In particular, if the main frame 3 is made of a material or thickness that does not have sufficient strength, reinforcing members, such as truss members that pass straight through the upward curved or bent portion described later, can be provided. The top portion 30 of the main frame 3 is curved or bent upwards in part or in whole between both ends in the longitudinal direction. The top portion 30 of the main frame 3 is curved or bent upwards to match the shape of the arch pipes 81 of the roof 80 of the vinyl greenhouse 8, thereby maintaining the curtain support height 7. Because the top portion 30 of the main frame 3 is curved or bent upwards to match the shape of the arch pipes 81, when the curtain spacer 2 is moved in the longitudinal direction to change its position, friction with the covering curtain 9 is reduced, allowing for smoother operation. In addition, a space of approximately equal height (or thickness) can be secured between the main frame 3 and the arch pipes 81.

[0037] The curtain support height 7 can be set to a height that does not place an excessive load on the roof 80 even when subjected to wind and snow, for example, a few centimeters or more and less than 1 meter. The curtain support height 7 can be set to, for example, 10 cm or more and 50 cm or less. Setting the curtain support height 7 to 10 cm or more ensures an air layer of 10 cm or more between the roof 80 and the covering curtain 9, thereby ensuring sufficient heat insulation and ventilation. Keeping the curtain support height 7 at 50 cm or less ensures heat insulation and ventilation between the roof 80 and the covering curtain 9, and also makes it easier to ensure durability when subjected to wind and snow. Furthermore, keeping the curtain support height 7 at 50 cm or less makes it easier to control the curtain spacer 2 by suppressing friction with the covering curtain 9 when positioning and moving it.

[0038] The support leg 4 can be formed, for example, by bending a metal strip into an isosceles triangle, with the lower surface of its base serving as the ground contact surface 40, and the end of the main frame 3 integrated at its vertex via welding or a connecting structure such as bolts and nuts. The ground contact surface 40 is preferably a smooth plane, and the support width 41 of the ground contact surface 40 can be set to a dimension 41 that exceeds the spacing 82 between two adjacent arch pipes 81 in the ridge direction of the flow-direction framework 81 of the roof 80 of the vinyl greenhouse 8. The support width 41 can be set to a dimension that adds a margin 42 to both ends of the spacing 82 to compensate for shearing movement. The ground contact surface 40 can be replaced, for example, with one or more pulleys. The ground contact surface 40 can be replaced, for example, with wheels that can roll freely on the framework 81 of the roof 80 (arch pipes 81 of the vinyl greenhouse 80, etc.) or the seam fastening portion of the roofing material. Furthermore, the support legs 4 do not necessarily have to be made of metal; they can also be made of wood, resin, or other materials. Also, if the support legs are made of pipes or the like, the contact surface 40 does not need to be flat.

[0039] As shown in Figure 4, the support leg 4 consists of a ground plate 43 with a smooth ground surface 40 and curved edges at both ends in the longitudinal direction of the main frame 3, and an arch-shaped or gate-shaped support frame 44 made of pipe or rod that spans between both ends of the support width 41 of the ground plate 43, and the main frame 3 can be connected to the uppermost part of the support frame 44. Since the ground plate 43 has curved edges at both ends in the longitudinal direction of the main frame 3, friction with the vinyl sheet 83 of the vinyl greenhouse 8 can be reduced. Since the support frame 44 is made of pipe or rod, the curtain spacer 2 can be made lighter and have a lower center of gravity.

[0040] As shown in Figures 1 and 2, both ends of the top portion 30 of the main frame 3 in the longitudinal direction are bent or cut downwards toward the outside and chamfered. Furthermore, each end of the main frame 3 has a connecting portion 5 such as a ring, hook, or carabiner that is inclined diagonally downward toward the outside toward the outside in the longitudinal direction. The connecting portion 5 can be suspended from the top of the support legs 4, which are located near the bottom of both ends of the main frame 3.

[0041] (Curtain spacing device) As shown in Figures 1, 2, and 3, the curtain spacing holding device 1 has a pair of tensioning harnesses 6 connected to each of the connecting parts 5 of the curtain spacers 2, and a length adjustment mechanism 61 provided on the tensioning harnesses 6. The pair of tensioning harnesses 6 can be made of straps, film bands, strings, ropes, wires, etc., that can temporarily fix the curtain spacers 2 with sufficient strength. The pair of tensioning harnesses 6 can be made of soft resin belts such as agricultural film tape, with a width set so as not to apply excessive friction or concentrated load to exterior parts such as vinyl sheets 83 of a vinyl greenhouse 8 or glass of a glasshouse. The pair of tensioning harnesses 6 can be made of synthetic resin fibers, natural fibers, resin films, natural rubber, leather, or other belts. The length adjustment mechanism 61 can be provided near the connecting parts 5.

[0042] The tensioning harness 6 has a length adjustment mechanism 61 on the looped end 60. The length adjustment mechanism 61 can be, for example, a buckle, clasp, fastening fitting, ratchet fitting, cargo securing device, etc. The length adjustment mechanism 61 connects the middle part of the tensioning harness 6, which is wrapped around the side beam 84 of the vinyl greenhouse 8 to form a loop, to the end 60, thereby adjusting the length of the tensioning harness 6 and allowing the installation position of the curtain spacer 2 to be adjusted in the direction of the flow of the roof 80.

[0043] As shown in Figures 1, 2, 3, and 5, the curtain spacing device 11 can have two curtain spacers 2 and 21 arranged in series with a gap between them, a connecting harness 62 connecting the opposing connecting parts 5 of the two curtain spacers 2 and 21, a pair of tensioning harnesses 6 connected to the connecting parts 5 at both ends of the two curtain spacers 2 and 21 arranged in series, and a length adjustment mechanism 61 provided on the tensioning harness 6. The connecting harness 62 can be made of the same or equivalent material as the tensioning harness 6. The connecting harness 62 is set to a length such that the middle section of the connecting harness 62 straddles the ridge 85 of the vinyl greenhouse 8 and the curtain spacers 2 and 21 are positioned so that their respective support legs 4 make contact with the ground along both flow directions on either side of the ridge 85 of the roof 80. The length adjustment mechanism 61 can be provided in the middle of the connecting harness 62.

[0044] (Installation method for parallel arrangement) As shown in Figures 1, 2, 3, and 5, the installation process involves arranging the curtain spacer 2 along one of the flow directions on either side of the ridge 85 of the roof 80 of the vinyl greenhouse 8, connecting the respective end loops 60 of the pair of tensioning harnesses 6 to the corresponding side beams 84 on either side of the ridge 85 of the roof 80, adjusting the length adjustment mechanism 61 to tension the tensioning harnesses 6, and installing the curtain spacing holding device 1.

[0045] The adjacent installation step involves placing adjacent curtain spacers 20 at a position adjacent to the curtain spacing device 1 installed in the installation step in the direction of the ridge 85, along the flow direction of the other side of the ridge 85 of the roof 80, connecting the end loops 60 of each of the pair of tensioning harnesses 6 of the adjacent curtain spacers 20 to the corresponding side beams 84 on one and the other side of the ridge 85 of the roof 80, adjusting the length adjustment mechanism 61 to tension the tensioning harnesses 6, and installing the adjacent curtain spacing device 10. The covering step involves covering the curtain spacers 2 and 20 with a covering curtain 9 such as cheesecloth over them after performing the adjacent installation step at least once. The covering curtain 9 is a curtain that is covered over the roof 80 and can be made of, for example, synthetic resin, synthetic fiber, nonwoven fabric, natural fiber, natural rubber, film, sheet, net, perforated sheet, knitted mesh sheet, or other materials.

[0046] In both the installation step and the adjacent installation step, the respective curtain spacers 2 and 20 can be arranged along the same flow direction on either side of the building 85. For example, in the adjacent installation step, the curtain spacers 20 of the adjacent curtain spacing device 10 can be arranged along the same flow direction on either side of the building 85 as the curtain spacers 2 of the curtain spacing device 1. Alternatively, in the installation step, the curtain spacers 2 can be arranged along the same flow direction on either side of the building 85 as the curtain spacers 20 of the adjacent curtain spacing device 10.

[0047] (Installation method for series configuration) As shown in Figures 1, 2, 3, and 5, the installation process involves arranging at least one of the two curtain spacers 2 along one of the flow directions on either side of the ridge 85 of the roof 80 of the greenhouse 8, placing the middle portion of the connecting harness 62 over the ridge 85, arranging the remaining curtain spacer 21 along the other flow direction on either side of the ridge 85 of the roof 80, roughly adjusting the length adjustment mechanism 61 of the connecting harness 62, adjusting the arrangement of both curtain spacers 2 in the flow directions, connecting the respective end loops 60 of the pair of tensioning harnesses 6 to the corresponding side beams 84 on either side of the ridge 85 of the roof 80, adjusting the position in the direction of the ridge 85, operating the length adjustment mechanism 61 to finally tension the tensioning harnesses 6, and installing the curtain spacing holding device 11.

[0048] The adjacent installation step allows for the installation of an adjacent curtain spacing device 11 next to the curtain spacing device 11, using the same process as the installation step, and arranged in the same flow direction as the curtain spacing device 11. The covering step allows for the covering curtain 9 to be placed over the curtain spacers 2 and 21 after the adjacent installation step has been performed at least once.

[0049] (Installation method combining parallel and series configurations) As shown in Figure 5, the curtain spacing device 11 can be installed next to the curtain spacing device 1, or next to the curtain spacing device 10. Alternatively, the curtain spacing device 11 can be arranged in series between the parallel-arranged curtain spacing device 1 and the adjacent-arranged curtain spacing device 10. [Industrial applicability]
