Description

[Technical Field]

[0001] The present invention relates to a film-attaching method for buildings that allows for easy application of film to film-attaching surfaces such as roofs and walls of buildings such as agricultural greenhouses, and to a film with a fastening frame used in the method. [Background technology]

[0002] In agricultural greenhouses (vinyl greenhouses), warehouses, workshops, and other buildings, the work of applying a film to the roof or walls, for example, the work of applying a film to the roof, as described in Patent Document 1, involves attaching a film holding frame to the roof surface and applying the film along the roof surface while fastening the film to the film holding frame. The film holding frame has film insertion grooves that open upward. The film is inserted into the film insertion grooves of the film holding frames, which are arranged at regular intervals along the roof surface, and then an inserting member such as a spring member is inserted into the groove from above, and the film is fastened to the film holding frame under a predetermined tension. This work is repeated. It should be noted that Patent Document 2 (tensile structure building) and Patent Document 3 (framed panel and roof structure of agricultural greenhouse) are cited in the description of the embodiments of the present invention. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-15906 [Patent Document 2] Patent No. 6865467 [Patent Document 3] Patent No. 5607955 Summary of the Invention [Problem to be solved by the invention]

[0004] The work of attaching film to the roof or walls of agricultural greenhouses and other buildings requires skilled workers to work at high altitudes on the roof or on poor footing. For this reason, improvements have been made to make the film attachment work easier, and as a result, a method has become widespread in which a hard film is attached with screws at a specified tension to a dedicated aluminum part that replaces Vinipet (registered trademark) as a film attachment frame.

[0005] However, this screw-type method requires more man-hours for film application than using vinyl sheets. There is also a risk of the film being damaged by the dedicated aluminum parts during the film application process. Furthermore, because the film is secured by screws, there is a risk of water leaking through holes created by the screws due to deterioration over time. In addition, when using dedicated aluminum parts, more fasteners are used than when using vinyl sheets, which increases the light-blocking area of ​​the roof and walls, resulting in a problem of reduced light transmittance into the greenhouse.

[0006] In view of the above, the object of the present invention is to propose a versatile film-covering method for buildings that allows film covering to be easily performed on the roof and wall surfaces of buildings such as agricultural greenhouses without relying on experience or skill, and that can be used for buildings of various structures. Another object of the present invention is to provide a film with a fixing frame that is produced in a factory for carrying out the method. [Means for solving the problem]

[0007] The film-attached surfaces such as roof surfaces and wall surfaces that have been covered with film by the film-attaching method of the present invention are as follows: an attachment surface structure constituting the film attachment surface; a plurality of film retaining frames attached to structural members constituting the attachment surface structure and extending in a direction along the film attachment surface; and The film is fixed to the film stop frame and is made of a flexible film stretched in a state where it covers the attachment surface structure, The film stop frame is a frame of a predetermined length, and a film insertion groove is formed along the length of the frame, the groove opening in a direction outward from the film attachment surface, The film portions facing the openings of the film insertion grooves of the film stop frame are inserted into and fixed in the film insertion grooves.

[0008] The film covering method for buildings of the present invention is as follows: a film with a stopper frame is produced in a factory, in which each of the film portions of the film is inserted and fixed into each of the film insertion grooves of the plurality of film stopper frames; When transporting the film to the installation site of the building, the film with the stopper frame is transported in a bundled or wound state, The film is attached to the film attachment surface of the building by repeatedly spreading the framed film from above the attachment surface structure, and positioning and fixing the film stop frame of the framed film to the structural member.

[0009] According to the present invention, a film with a retaining frame is manufactured in advance in a factory, in which a film is attached to a film retaining frame. Since a film with a retaining frame is simply a flexible film attached to a film retaining frame, the film can be folded and bundled or wound up around the film retaining frame, making it convenient for transport in a reduced volume.

[0010] The film is stretched between the film clamping frames in an appropriate manner during factory production, and the film is secured to the film clamping frames in an appropriate manner. At the site, the film installation work on the roof surface is completed by repeatedly unfolding the film with the framed roofing film on the surface to which the film is to be installed, such as a roof surface, and positioning and connecting the film clamping frames to the roof surface structural members so that they are spaced at predetermined intervals. The film installation can be completed through the simple process of unfolding the film with the framed film and connecting and fixing each film clamping frame to the structural members at predetermined intervals.

[0011] Here, taking into consideration the transportation and handling of the framed film, the size of the film application surface, etc., it is also possible to divide the film application surface into multiple sections, produce multiple sheets of film with retaining frames corresponding to each section, transport them to the site, and then perform the film application work on the building.

[0012] For example, in the case of agricultural greenhouses, agricultural films with a predetermined width are commercially manufactured and sold. In factory production, a film with a frame of the required width can be obtained by joining the required number of films in the width direction via a film frame. [Effects of the Invention]

[0013] According to the present invention, the film application work on the film application surfaces of buildings can be simplified, and roofs, walls, etc. can be constructed with film applied in an appropriate state without relying on experience or skill. Furthermore, if a fixing device for fixing the film holding frame to the structural member is prepared that corresponds to the structural member of the building, versatility can be achieved in that film application can be performed on the film application surfaces of buildings with various structures such as pipe structures, steel frame structures, and wire structures.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of a film cladding method for a building to which the present invention is applied will be described with reference to the drawings. Note that the embodiment shows an example of the present invention and is not intended to limit the present invention to the embodiment. For example, buildings to which the present invention can be applied are not limited to agricultural greenhouses such as greenhouses, but also include warehouses, workshop buildings, and other buildings for various other purposes, and are not limited to any particular building.

[0016] [Embodiment 1] (Overall composition) The structure of a greenhouse building for strawberry cultivation, to which the present invention can be applied, will be described with reference to Figure 1. The greenhouse building 1 is a tensile structure building, and its structure is basically composed of metal single pipes that bear compressive forces and high-tension, high-strength wire ropes that bear tensile forces. The specific structure of the tensile structure greenhouse building is similar to that described in Patent Document 2 (Patent Publication No. 6865467: Buildings with Tension Structures), so a detailed description thereof will be omitted.

[0017] The greenhouse building 1 comprises front and rear gable wall frames 3F, 3B (gable wall structures), left and right flat wall frames 4L, 4R (flat wall structures), and a central frame 5 extending in the longitudinal direction Y (beam direction) at the center of the horizontal direction X (span direction). The roof surface 6 of the greenhouse building 1 is composed of multiple wire ropes 11 (structural members) stretched under a predetermined tension in the longitudinal direction Y, and multiple wire ropes 12 (structural members) stretched under a predetermined tension in the flow direction of the roof surface in the horizontal direction X (span direction). Similarly, the horizontal ceiling surface 7 below is composed of multiple wire ropes 13 (structural members) stretched under a predetermined tension in the horizontal direction X, and multiple wire ropes 14 (structural members) stretched under a predetermined tension in the vertical direction Y.

[0018] The front and rear gable wall frames 3F, 3B and the left and right flat wall frames 4L, 4R, across which the wire ropes 11-14 are stretched, are pulled outward in the front-to-back direction Y and outward in the left-to-right direction X by front and rear gable anchor wire ropes 15 and flat side anchor wire ropes 17, 18 on both sides. The flat side anchor wire rope 17 extends diagonally outward on the left and right sides of the greenhouse building 1. These wire ropes 15, 17 are hooked to anchor steel materials 81 buried in the ground G, which is the installation surface.

[0019] A plurality of translucent gable wall films 21 are attached to the outer surfaces of the gable wall frames 3F, 3B, respectively, and a plurality of translucent flat wall films 22 are attached to the outer surfaces of the flat wall frames 4L, 4R, respectively. A roofing film 30 is attached to the roof surface 6 in a factory, with a translucent film 23 pre-attached to a film fastening frame 31.

[0020] (roofing film) FIG. 2 is an explanatory diagram showing a roofing film 30 (film with a fastening frame) stretched on a roof surface 6, which is the film-attaching surface. The roof surface 6 covered with the roofing film 30 is basically composed of a plurality of wire ropes 11 (hereinafter referred to as "vertical wire ropes 11") and a plurality of wire ropes 12 (hereinafter referred to as "horizontal wire ropes 12") for constituting the roof surface. The vertical wire ropes 11 are arranged at a constant pitch in the front-to-back direction Y, and are stretched in the direction of the flow of the roof surface along the roof surface 6 in the left-to-right direction X. The horizontal wire ropes 12 are arranged at a predetermined pitch in the direction of the flow of the roof surface in the left-to-right direction X, and extend in the front-to-back direction Y on the underside (indoor side) of the vertical wire ropes 11.

[0021] Left and right ridge-side mounting iron plates 25 extending horizontally in the front-to-back direction Y are attached to the left and right sides of the ridge single pipe 72 on the roof surface. In addition, eaves-side mounting iron plates 26 extending horizontally along the single pipes 64 arranged horizontally at the upper ends of the left and right flat side wall frameworks 4L, 4R are attached.

[0022] In the roofing film 30 stretched over the roof surface, each film holding frame 31 is suspended from above (the exterior side) over the horizontal wire rope 12, arranged at a regular pitch in the front-to-rear direction Y, and extends in the direction of the roof surface flow in the left-to-right direction X. Each film holding frame 31 is suspended from above (the exterior side) of the horizontal wire rope 12 between the ridge-side mounting iron plate 25 and the eaves-side mounting iron plate 26 on both sides of the ridge, and is connected and fixed to these plates using dedicated connectors 27, 28. Furthermore, at the intersection with the horizontal wire rope 12, each film holding frame 31 is connected and fixed to the horizontal wire rope 12 from below (the interior side) by a raised connector assembly 40. The material of these film holding frames, connectors, and connector assemblies is not limited to metal, and various materials such as resin can be used.

[0023] (Film holding frame) FIG. 3 is an explanatory diagram showing a film retaining frame 31 and a raised connector assembly 40 in a roofing film 30. The film retaining frame 31 can be, for example, a commercially available product under the trade name Vinypet (registered trademark). The film retaining frame 31 is not limited to commercially available products such as Vinypet. Film retaining frames of various shapes, structures, and materials can be used as long as they can be inserted into holes in the film to secure it. As shown in FIG. 3( a), each film retaining frame 31 has a film retaining groove 31a extending in the length direction and opening on the upper side (outdoor side). In the roofing film 30, the film 23 is stretched so as to cover the film retaining frame 31 from the outdoor side, and the film portion 23a facing the film retaining groove 31a is inserted into the film retaining groove 31a. The inserted film portion is fixed in the film retaining groove 31a by a wave-folded spring material 29 (a groove-fitting member) attached to the film retaining groove 31a from above. Such a film stop mechanism is well known and will not be described in detail.

[0024] (Raised coupling assembly) As shown in FIG. 3(b), the raised connector assembly 40 connects the film holder frame 31 to the horizontal wire rope 12 at a predetermined distance in the raised direction (toward the outdoors, upward away from the horizontal wire rope 12), and includes a connector 41 and a wedge fitting 42. The connector 41 is a U-shaped metal fitting with a bottom plate portion 41a and side plate portions 41b formed on both sides of the bottom plate portion 41a. Each of the side plate portions 41b has a rectangular opening that opens to its tip, and engaging claws 41d that protrude toward each other are formed on the inner edge portions on both sides of the tip of the rectangular opening. The connector 41 can be attached to the film holder frame 31 in a hanging state, with the engaging claws 41d engaging with both sides of the bottom surface of the film holder frame 31 from below.

[0025] The wedge fitting 42 is a U-shaped fitting with a rectangular bottom plate portion 42a and side plate portions 42b formed on both sides. The left and right side plate portions 42b are wedge-shaped, and their height gradually decreases from one end of the side plate portion 42b to the other. In this example, the upper end surfaces of the side plate portions 42b are inclined end surfaces. In addition, a wire rope insertion groove 42c extending in the front-to-rear direction is formed in the center of the bottom plate portion 42a.

[0026] At the intersection of the film holder frame 31 and the horizontal wire rope 12, a connector 41 is inserted between the film holder frame 31 and the horizontal wire rope 12 from below and connected to the film holder frame 31 in a suspended state. The horizontal wire rope 12 is sandwiched between the wire rope passage groove 42c of the wedge fitting 42 and the connector 41. In this state, the wedge fitting 42 is inserted between the bottom surface of the film holder frame 31 and the connector 41. As a result, the film holder frame 31 is connected and fixed to the horizontal wire rope 12 in a state where it is raised above the horizontal wire rope 12 (vertical wire rope 11) as shown in the figure.

[0027] (Production of roofing film) The roofing film 30 stretched on the roof surface of the greenhouse building 1 in this example was manufactured in a factory, delivered to the site with the film 23 already secured to the film retaining frames 31, and then attached to the roof surface. In other words, in the past, it was necessary to climb onto the roof, connect and secure each of the film retaining frames 31 to the horizontal wire ropes 12, and then unfold the film 23 and insert and secure it into each of the film retaining frames 31 so that it was tensioned as desired. In contrast, in this example, the roofing film 30 with the film 23 already attached to the film retaining frames 31 is manufactured in the factory, delivered to the site, and the roofing film 30 is placed on the roof and unfolded over the horizontal wire ropes 12. The film 23 installation process is then completed by simply connecting and securing each of the film retaining frames 31 to the horizontal wire ropes 12. This eliminates the need to insert and secure the film 23 into the film retaining frames 31 in the appropriate tension on the roof. The film 23 can be properly inserted into the film holding frame 31 and fixed, and can be stuck in a proper tensioned state, without requiring any skill or experience.

[0028] As shown in FIG. 2, the roofing film 30 of this example comprises multiple films 23 of the same width and length and multiple film retaining frames 31. The film retaining frames 31 are arranged in parallel at a constant pitch. If adjacent film retaining frames 31 are referred to as the left and right film retaining frames, the left long edge of each film 23 is inserted into the film retaining groove of the left film retaining frame and fixed therein by a spring member (a member fitted into the groove). Similarly, the right long edge of each film 23 is inserted into the film retaining groove of the right film retaining frame and fixed therein by a spring member (a member fitted into the groove). It is also possible to insert the film along the film retaining groove and fix it with an adhesive without using a spring member, for example.

[0029] In this way, the roofing film 30 has film retaining frames 31 arranged at both ends in the width direction, and films 23 of a certain width are stretched between the film retaining frames 31 arranged at a certain pitch between them, and both sides of each film 23 are inserted into and fixed in the film retaining grooves 31a of the film retaining frames 31.

[0030] Figure 4 is an explanatory diagram showing the manufacturing process and manufacturing jig for roofing film 30 in a factory. Referring to this figure, film retaining frames 31 are placed horizontally (from the rear in the figure) onto stand 210 of manufacturing jig 200, and two film retaining frames 31 are arranged parallel to each other at a fixed pitch with film retaining grooves 31a facing upward. Commercially available agricultural films come in widths of 1 m, 1.2 m, and 1.5 m, and the pitch can be adjusted to accommodate these.

[0031] A constant width of film 23 is unwound from film supply roll 220, which is located on one side in the vertical direction, along the top surface of film holder frame 31. After film 23 is supplied so as to cover the entire length of film holder frame 31, left long edge 23L and right long edge 23R of film 23 are inserted into film holder grooves 31a of two film holder frames 31, and spring members (members to be fitted into the grooves) are fitted in from above, and both side portions of film 23 are inserted and fixed in film holder frames 31.

[0032] After the film 23 has been stretched between the pair of film retaining frames 31, it is slid sideways from the left film retaining frame 31 side and placed in a vertically stretched film storage and transport box 230 located on the lower side of the stand 210. The other film retaining frame 31 and the next film retaining frame 31 are placed at a fixed pitch on the stand 210. After this, the film 23 is unwound from the film supply roll 220 and stretched between these two film retaining frames 31, with both side sections inserted and fixed in place. By repeating these steps, a roofing film 30 of a fixed length and width is obtained.

[0033] For example, for a building with a width of 11 m, the length of the film holding frame 31 for vertical installation is 6 m. The width of the film 23 to be installed is in accordance with commercially available film standards (1 m, 1.2 m, 1.5 m). The roofing film 30, which is a factory-produced film assembly with film frames, is equipped with a film holding frame 31 in units of several to several dozen rolls, but the film 23 can be folded and bundled for transport to the construction site.

[0034] During film installation work at the greenhouse building 1 installation site, the roofing film 30 is spread in the girder direction Y along the horizontal wire ropes 12 from above the horizontal wire ropes 12 and vertical wire ropes 11. Adjacent film stop frames 31 are spread and positioned from one side of the girder direction Y so that the film 23 between them is in an appropriate tension state, and in this state are connected and fixed to the horizontal wire ropes 12 using the raised connector assemblies 40. By repeating this process, the film-covered roof surface can be constructed.

[0035] In this way, there is no need to insert and secure the film 23 into the film retaining frames 31. Simply positioning each film retaining frame 31 in order and connecting and securing it to the horizontal wire rope 12 is all that is required, simplifying the process. The film 23 can be stretched appropriately and easily inserted and secured into the film retaining frames 31 in the appropriate position. Furthermore, dedicated connecting hardware for attaching the film retaining frames 31 to the ridge and eaves is sufficient. This eliminates the need for skilled technical processes, simplifies the process, and improves work efficiency and quality. Furthermore, applying the roofing film 30 to a tension house constructed with wire ropes, as in this example, can further reduce costs and maintain high light transmittance.

[0036] [Embodiment 2] The film-attaching method for buildings of the present invention is not limited to buildings with a tensile structure as described in the first embodiment, but can be applied to buildings with various structures such as general pipe structures, steel frame structures, etc. Furthermore, the film-attaching method of the present invention can be used not only for roof surfaces, but also for film attachment work on wall surfaces and other film-attaching surfaces.

[0037] 5 is an explanatory diagram showing a building with a gable face to which a film is applied using the film application method of the present invention. The gable face 110, which is one of the film-applied faces of the building 100, is made up of a gable-side wall framework (gable-side wall structure) consisting of multiple vertical single pipes 111 (structural members) arranged vertically at a predetermined interval, multiple horizontal single pipes 112 (structural members) laid horizontally between them, and single pipes 113 for rafters on the left and right that are laid across the upper ends of the vertical single pipes 111.

[0038] A gable-side wall film 130 (film with a retaining frame) is attached to the outside of the gable face 110 under a predetermined tension. Specifically, multiple (e.g., nine) film retaining frames 141-149 are vertically arranged at predetermined intervals in the span direction between the installation surface and the rafter unit pipe 113. Each of these film retaining frames 141-149 is fixed to the horizontal unit pipe 112 at the intersection with the frame by a pipe joint 150. In the figure, the fixed position by the pipe joint 150 is indicated by a circle with a dashed line, and the fixed portion between the horizontal unit pipe 112 and the film retaining frame 146 by the pipe joint 150 is shown as viewed from the inside of the greenhouse. A commercially available pipe joint 150 can be used for the pipe joint 150, but a dedicated pipe joint may also be used. Any type of pipe joint can be used as long as it can secure two orthogonal members at their intersection, regardless of its shape, structure, or material.

[0039] Between the film clamping frames 141-149, films 131-138 constituting the end side wall film 130 are stretched under a predetermined tension. In this example, eight films 131-138 of a predetermined width are attached between adjacent film clamping frames 141-142, 142-143, 143-144, 144-145, 145-146, 146-147, 147-148, and 148-149. The long side edges on both sides in the width direction of each end side wall film 131-138 are fixed in film clamping grooves formed in the film clamping frames 141-149. The film clamping frames 141-149 have the same structure as the film clamping frames described in the first embodiment, and therefore a description thereof will be omitted.

[0040] In this example, too, the gable side wall film 130 (film with retaining frames), which is configured by attaching eight gable side wall films 131 to 138 to nine film retaining frames 141 to 149, is produced in a factory and transported to the installation site of the building 100.The film is attached to the gable side 110 by repeatedly spreading out the gable side wall film 130 and fixing the film retaining frames 141 to 149 sequentially to the horizontal single pipe 112 on the gable side 110 with pipe joints 150.

[0041] In this way, the gable-side wall film 130 is produced in a factory, making on-site film application easy and simple. Also, as in this example, the film retaining frames 141-149 can be attached at any interval to the horizontal single pipe 112, which is a structural member of the gable surface 110, by pipe joints 150. Therefore, even framed films made by joining films of different widths can be easily applied.

[0042] In the first and second embodiments, the framed film produced in a factory is described as having film retaining frames arranged parallel to each other at regular or varying intervals. In the framed film of the present invention, the film retaining frames do not have to be parallel. For example, as proposed in Patent Document 3 (Japanese Patent No. 5607955: Framed Panel and Roof Structure of Agricultural Greenhouse), a framed film is prepared in which two film retaining frames constituting two sides of a triangular panel are attached to two sides of a triangular film produced in a factory. This can be transported to an installation site, and on the roof surface, the film retaining frames on two sides of the framed film are fixed to a roof surface structural member, and the remaining side of the film is attached to a film retaining frame fixed to the roof surface structural member, thereby forming a triangular panel, which can then be combined to form a film-attaching surface.

[0043] As explained above, according to the present invention, the film application work on the film application surfaces of buildings can be simplified, and roof surfaces, wall surfaces, etc. can be constructed with film applied in an appropriate state without relying on experience or skill. Furthermore, by using a fixing device that is compatible with the structural members of the building as a fixing device for fixing the film holding frame to the structural members, film application can be performed on the film application surfaces of buildings with various structures such as pipe structures, steel frame structures, and wire structures, thereby realizing a highly versatile film application method.
