Description

  The present invention relates to a roof greening facility for a folded plate roof suitable for construction on the folded plate roof.

In recent years, for the purpose of improving the urban environment against global warming and the like, rooftop greening facilities that can be installed by effectively utilizing the rooftop space of buildings and condominiums and the roof space of houses are becoming widespread.
As such rooftop greening facilities, the rooftop garden type and the thin-layer greening type have been put into practical use, and in particular, the thin-layer greening type thin-layer rooftop greening facility is markedly compared to the rooftop garden-type rooftop greening facility. It is lightweight, can be easily applied to existing buildings, can maintain good drainage, and can suppress temperature changes on the rooftop surface of the building, thus improving the durability of the building and blocking the building. It has attracted attention because it has excellent advantages such as high temperature and heat retention and reduced utility costs.

  As the thin-layer rooftop greening facility, a waterproof sheet was laid on the building, and a thin-layer greening laminate was installed on the drainage mat, a root shielding sheet, and a planting mat in order from the bottom. Things are in practical use. And, as a planting mat, by using a vegetation centered on sedum excellent in drought resistance in a thin cultivated soil and using a mat shape, it is possible to set the water retention amount for a thin greening laminate low, It is configured to reduce the weight of the thin greening laminate and to prevent a decrease in the durability of the building due to a decrease in temperature change and a blocking of ultraviolet rays.

  On the other hand, various kinds of folded-plate roof greening facilities that can be constructed on folded-plate roofs of factories and the like have been proposed. For example, Patent Document 1 describes a folded plate roof planting facility in which plant vegetation material is set in a valley portion of a folded plate roof and plants are planted on the plant vegetation material. In this publication, as plant vegetation materials, for example, mineral fibers such as rock wool and ceramic wool, or recycled materials such as coconut shells, bark, or car shredder dust are formed into a predetermined shape. The product having water retention was manufactured.

Patent Document 1 describes a roof planting facility in which a heat insulating material made of a water-impermeable member is arranged on a folded plate roof and a planting device is provided thereon.
JP 2000-166375 A JP 2002-95348 A

By the way, although the thin-layer greening facility has a certain degree of achievement, the actual situation is that the roof greening facility with the folded-plate roof has not yet been fully studied.
For example, in the roof planting facility described in Patent Document 1, the number of component parts is small and construction is possible at a low cost. However, since the soil is set up to the middle of the depth direction in the valley of the folded plate roof, Drainage is not smooth, and if the amount of rainwater increases, the soil will be washed away with the rainwater, the roof strength when the soil is heavy with rainwater cannot be secured, and the greening area cannot be set large, Since the moist soil is always in contact with the folded plate roof, there is a problem that the folded plate roof is easily damaged.

  Further, in the roof planting facility described in Patent Document 2, since the planting device is arranged on the heat insulating material from the water-impermeable member, the durability of the folded plate roof due to the wet culture soil directly contacting the folded plate roof. However, since the drainage structure of the folded-plate roof cannot be used as it is, the drainage structure becomes complicated, and it is difficult to secure sufficient bending strength of the heat insulating material at the position corresponding to the valley. There is a problem that when the worker gets on the heat insulating material for construction of the planting device or due to secular change, the heat insulating material is deformed into the valley and cannot be restored.

  An object of the present invention is to provide a roof planting facility for a folded-plate roof capable of simply and sufficiently constructing a planting mat of a thin-layer roof planting facility that has been proven in rooftop planting.

The roof greening facility for a folded-plate roof according to claim 1 has a substantially flat mounting surface for receiving an overload on the upper surface, and a plurality of fixedly installed along the length direction at the top of the mountain portion of the folded-plate roof. Joist frame, a substantially flat mesh member laid and fixed over the plurality of joist frames, a planting layer provided on the mesh member, and a valley portion of the folded plate roof at both upper and lower ends of the folded plate roof And a closing plate for closing the trough with the opening left at the bottom .

  In this roof planting facility, a net-like member is fixedly installed on a folded-plate roof with a joist frame interposed, and a planting layer is provided thereon, so even if the roof gradient is relatively large, the construction work is complicated. The planting layer can be stably installed on the folded-plate roof while preventing this.

  In other words, it is possible to directly fix and install the mesh member on the folded plate roof using a sword tip bolt or the like protruding upward from the folded plate roof, and to provide a planting layer thereon, but the slope of the roof For example, when the steep slope is 1/50 or more, it is considered that the planting layer slides with the mesh member, and if a new fixing point is provided in addition to the sword bolt to prevent this slipping, the number of parts increases. The construction work becomes complicated.

  On the other hand, in the present invention, since the joist frame is fixed to the top of the mountain portion of the folded plate roof, a sufficient contact area between the joist frame and the folded plate roof is secured, and the sliding direction is caused by frictional resistance with the folded plate roof. The shear load acting on the sword bolt can be reduced, and the joist frame can be securely fixed to a folded plate roof having a relatively large gradient without increasing the fixing point. In addition, since the mesh member is fixedly installed on the substantially flat mounting surface of the joist frame, the mesh member can be fixed at an arbitrary position of the joist frame, and sufficient attachment strength of the mesh member to the joist frame is ensured. it can.

  In this way, the mounting strength of the joist frame to the folded plate roof can be sufficiently secured with a small number of fixing points, and the mounting strength of the mesh member to the joist frame can be sufficiently secured. While preventing the work from becoming complicated, the planting layer can be reliably fixed to the folded roof with only the sword bolt for fixing the folded roof. In addition, when applied to a folded-plate roof fixed with a goby, the contact area between the joist frame and the folded-plate roof can be sufficiently secured in the same manner as a folded-plate roof fixed with a sword bolt, so the groundwork of the planting layer The net-like member as the material can be firmly fixed to the folded plate roof.

  In addition, by using a metal member as the mesh member, the strength of the mesh member at the position corresponding to the valley of the folded plate roof can be sufficiently secured, so the mesh member when constructing a planting layer, etc. It is possible to reliably prevent deformation of the mesh member due to deformation and aging. Thus, a light and stable substantially flat installation surface can be formed on the folded plate roof by the net-like member, so that the planting layer can be stably constructed.

In addition, if such a net-like member is used, the rainwater on the planting layer can be drained directly to the valley of the folded plate roof, and the drainage structure of the folded plate roof can be used to drain the rainwater, making the configuration complicated. Therefore, it is possible to realize roof greening equipment with excellent drainage. In addition, since the planting layer itself does not directly contact the folded plate roof, it is possible to prevent corrosion of the folded plate roof, etc., and to prevent a decrease in the durability of the folded plate roof due to sunlight, and the service life of the folded plate roof Can be improved.
Furthermore, since the closing plate which closes a trough part is provided in the upper-and-lower-ends part of the said folded-plate roof in the state which left the opening in the bottom part of the trough part of a folded-plate roof, it is excessive in the trough part of a folded-plate roof. Limiting the inflow of air, preventing drying of the planting mat and promoting the growth of vegetation, and restricting the blowing of wind into the valley, and the force that pushes up the planting mat from below Suppressing and effectively preventing the peeling of the planting mat during storms or strong winds.

  Here, a planting mat may be laid on the mesh member as the planting layer, and the plant mat may be fixed to the mesh member via a plurality of planting fixtures. In this case, the planting mat as the planting layer can be fixed to the mesh member with the planting fixture provided at an arbitrary position of the mesh member, and the attachment strength of the planting layer to the mesh member can be sufficiently secured. The entire roof planting facility can be firmly fixed to the folded roof. In addition, as described above, a light and stable substantially flat installation surface can be formed on the folded plate roof by the mesh member, so that a light and simple planting mat of a thin green planting facility with a proven track record in rooftop greening can be used for the mesh member. It is possible to construct the upper side as it is.

  You may use what provided the drainage mat which has the water permeability installed on a mesh member as the said planting mat in the lower part. As the net-like member, for example, a metal expanded metal is used, but the expanded metal having a strength that can withstand the work on the valley portion has a relatively large opening. When the planting base mat is directly installed, these sheets and mats protrude from the openings of the net members and the planting mat is damaged. For this reason, for example, a drainage mat formed by compression molding a synthetic resin wire is provided at the lower part of the planting mat, and is configured to receive the root shielding sheet or planting base mat. It is preferable to prevent the mat from being damaged. In addition, such a drainage mat is excellent in air permeability, so that it is possible to secure the air flow in the direction over the mountain, and to obtain a temperature reduction effect at a high temperature and a heat retention effect at a low temperature. Is possible.

  As the planting fixing bracket, a support, a fixing means for fixing the lower end of the support to the mesh member, and a top plate arranged at the upper end of the support, the planting mat is pressed against the mesh member to plant You may use what was provided with the top board which fixes a mat | matte to a net-like member. If the planting fixture of such a structure is used, a planting mat can be fixed to a mesh member by fixing a support | pillar to the arbitrary positions of a mesh member.

  The fixing means includes a lower base plate that can be inserted downward from the opening of the mesh member, and an upper base plate disposed on the upper side of the mesh member, and the mesh member is interposed between the upper and lower base plates via a support column. What clamps and fixes a support | pillar to a net-like member may be used. In this case, since a support | pillar can be fixed from the upper side after laying a net-like member, it becomes possible to construct a planting fixing metal fitting easily. In addition, by adjusting the length of the lower base plate, the column can be fixed at an arbitrary position of the opening of the mesh member, so that the side edge of the planting mat can be easily and reliably held by the planting fixture. Is possible.

  The planting mat provided with a drainage mat was used, and as the planting fixture, an intermediate plate for pressing the drainage mat to the mesh member side and fixing the drainage mat to the mesh member was disposed in the middle part of the column. A thing may be used. When using a planting mat with a drainage mat, after the drainage mat has been installed, a root shield sheet, a vegetation base mat, etc. will be installed on the drainage mat, but the folded plate roof has a slope. It is considered that the drainage mat is shifted during the construction work. In the present invention, since the drainage mat can be sequentially fixed to the mesh member with the intermediate plate, it is possible to sufficiently ensure the safety of construction work such as the root shielding sheet and the vegetation base mat.

  The mesh member may be a diamond-shaped opening, and the mesh member may be constructed so that the longer diagonal of the opening is substantially perpendicular to the longitudinal direction of the mountain portion of the folded plate roof. In order to effectively receive the load of the worker riding on the mesh member, for example, when using a diamond-shaped opening as a mesh member like expanded metal, the longer diagonal of the opening is the peak of the folded plate roof It is preferable to construct the mesh member so as to be substantially orthogonal to the longitudinal direction of the. Further, in the case of using a mesh member having such a rhombus-shaped opening, for example, when the mesh member is sandwiched by fixing means composed of upper and lower base plates, the outer peripheral outer end is extended from one end on the long side as the lower base plate. Using a plate-like member whose length up to the length of the shorter diagonal of the opening of the mesh member is less than the length of the longer diagonal, the column can be fixed at an arbitrary position within the opening. Therefore, it is preferable.

  As the joist frame, a fixed frame made of a channel material fixed to a sword bolt or goby for fixing a folded plate roof, a main body frame made of a channel material arranged continuously to the fixed frame, a fixed frame and a main body frame You may use what has a connection member to connect. Usually, the folded plate roof is fixed to the building at fixed points such as sword bolts and goby. However, in the folded plate roof fixed by sword bolts, the position of the sword bolts varies depending on the building. It is necessary to carry out construction on site. However, forming attachment holes and the like in the joist frame in correspondence with the sword bolt at the construction site increases the burden on the site and reduces workability. In the present invention, the joist frame is divided into a fixed frame, a main body frame, and a connecting member, so that necessary processing such as a mounting hole of a sword bolt is applied to the fixed frame in advance at a factory, etc. The joist frame can be assembled to the folded roof by a simple operation of cutting the main body frame according to the pitch of the sword tip bolt and connecting the fixed frame and the main body frame via the connecting member. Further, such a configuration is preferable because the joist frame can be applied as it is to a folded plate roof fixed with a goby simply by replacing the fixed frame.

  You may provide the planting base mat provided with the base mat which has water permeability on the upper part of the said planting mat, and the culture | cultivation holding | maintenance part of the solid network structure which consists of the fiber material fixed on the base mat. In this case, since the cultivation soil can be sprayed and held against the cultivation holding portion of the planting base mat after construction of the planting mat, when the cultivation soil is held on the roof in advance. Compared to the above, it is possible to lift the planting mat on the roof without using a large crane or the like.

  As the joist frame, a frame that becomes bulky as it goes to the eave side at an angle that matches the gradient of the folded plate roof, and that can be fixedly installed on the top of the mountain portion of the folded plate roof so that the upper surface becomes substantially horizontal may be used. Good. In this case, the mesh member can be arranged substantially horizontally, and it goes without saying that the above-mentioned vegetation mat can be laid on the mesh member, and a drainage mat or a root shielding sheet is laid on the mesh member for embankment. It is possible to plant flower beds and shrubs as well as the ground.

  You may provide the connection member which connects the joist frame arrange | positioned adjacently on both sides of the trough part of the said folded-plate roof. In this case, it is possible to prevent a lateral fall due to the bulk of the joist frame.

  According to the roof greening facility for the folded plate roof according to claim 1, the joist frame is fixed to the top of the mountain portion of the folded plate roof, and the mesh member is fixedly mounted on the substantially flat mounting surface of the joist frame. The net-like member as the base material of the tree layer can be reliably fixed to the folded roof with only the sword bolt for fixing the folded roof. In addition, when applied to a folded-plate roof fixed with a goby, the contact area between the joist frame and the folded-plate roof can be sufficiently secured in the same manner as a folded-plate roof fixed with a sword bolt, so the groundwork of the planting layer The net-like member as the material can be firmly fixed to the folded plate roof. Moreover, it can be applied to the existing folded-plate roof and can be easily constructed because it does not require any processing on the folded-plate roof.

In addition, the rainwater on the planting layer can be drained as it is to the valley of the folded-plate roof, and drainage can be drained by utilizing the drainage structure of the folded-plate roof. A roof greening facility can be realized. In addition, since the planting layer itself does not directly contact the folded plate roof, it is possible to prevent corrosion of the folded plate roof, etc., and to prevent a decrease in the durability of the folded plate roof due to sunlight, and the service life of the folded plate roof Can be improved.
Furthermore, since the closing plate which closes a trough part is provided in the upper and lower both ends of a folded-plate roof in the state which left the opening at the bottom part of the trough part of a folded-plate roof, excessive air into the trough part of a folded-plate roof The inflow of water can be restricted, and the growth of vegetation can be promoted by preventing the drying of the planting mat, and the blowing force from the lower side acts on the planting mat by restricting the blowing of wind into the valley. Suppressing and effectively preventing the peeling of the planting mat during storms or strong winds.

  Here, when a planting mat is laid on the mesh member as the planting layer and the planting mat is fixed to the mesh member via a plurality of planting fixtures, the entire roof planting facility is folded against the folded roof. It can be securely fixed only with the sword bolt for fixing the plate roof. In addition, a lightweight and stable, almost flat installation surface can be formed on the folded-plate roof by the net-like member, so that the planting mat of a light and simple thin-layer planting facility that has been proven in roof greening is directly applied to the upper side of the net-like member It becomes possible to do.

  When using a water-permeable drainage mat installed on the net member as the planting mat at the bottom, it is possible to prevent the root shield sheet and planting base mat from being damaged, and to overcome the mountain area. It is possible to secure the flow of air and obtain a temperature reduction effect at a high temperature and a heat retention effect at a low temperature.

  As a fixing means, when a thing provided with a lower base plate and an upper base plate is used, a support member can be fixed from the upper side after laying a mesh member, so that it is possible to easily construct a planting fixture. Become. In addition, by adjusting the length of the lower base plate, the column can be fixed at an arbitrary position of the opening of the mesh member, so that the side edge of the planting mat can be easily and reliably held by the planting fixture. Is possible.

  Using a plant with a drain mat as a planting mat, and as a planting fixture, an intermediate plate that presses the drain mat against the mesh member and fixes the drain mat to the mesh member in the middle of the column If it uses, it will become possible to fully secure the safety of construction work, such as a root shield sheet and a vegetation base mat.

  When the mesh member is constructed so that the opening has a rhombus shape and the diagonal line of the longer opening is substantially perpendicular to the longitudinal direction of the peak portion of the folded plate roof, it is at a position facing the valley portion of the folded plate roof. It becomes possible to effectively receive the load when the worker gets on. Further, in the case of using a mesh member having such a rhombus-shaped opening, for example, when the mesh member is sandwiched by fixing means composed of upper and lower base plates, the size of the lower base plate is set appropriately, thereby opening the mesh member. Since a support | pillar can be fixed to arbitrary positions in the inside, it is preferable.

  When a joist frame is used that has a fixed frame, a main body frame, and a connecting member, necessary processing such as mounting holes for sword tip bolts is applied to the fixed frame in advance at a factory, etc. The joist frame can be assembled to the folded plate roof by a simple operation of cutting according to the pitch of the bolt and connecting the fixed frame and the main body frame via the connecting member. Further, such a configuration is preferable because the joist frame can be applied as it is to a folded plate roof fixed with a goby simply by replacing the fixed frame.

  If a planting base mat equipped with a water-permeable base mat and a three-dimensional network-structured soil holding part made of fiber material fixed on the base mat is provided on the top of the planting mat, Since the soil can be sprayed and held against the soil holding part of the planting base mat, use a large crane, etc., compared to the case where the soil with the soil previously held on the planting mat is lifted on the roof Therefore, the planting mat can be lifted on the roof for construction.

  As the joist frame, when going to the eaves side at an angle that matches the gradient of the folded plate roof, using a thing that can be fixedly installed on the top of the mountain portion of the folded plate roof so that the upper surface is substantially horizontal, Needless to say, the net member can be arranged substantially horizontally, and the vegetation mat can be laid on the net member. And vegetation such as shrubs can be planted on the ground.

  Providing a connecting member that connects the joist frames arranged adjacent to each other with the valley portion of the folded plate roof interposed therebetween can prevent the jogging of the joist frame from becoming bulky.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1 to FIG. 5 and FIG. 10, the roof greening facility 1 is installed on a folded-plate roof 2 of a building, and has a substantially flat mounting surface 10 a that receives an overload on the upper surface, As a planting layer, a plurality of joist frames 10 fixedly installed along the length direction on the top of the mountain portion 4 of the folded plate roof 2, a substantially flat mesh member 20 laid and fixed over the plurality of joist frames 10, and A planting mat 30 laid on the mesh member 20 and a plurality of planting fixtures 40 for fixing the planting mat 30 to the mesh member 20 are provided. Moreover, the net-like member 20 is formed to the vicinity of the outer edge of the folded plate roof 2, a partition material 50 is provided at the outer edge portion of the roof greening facility 1, and a parting material 60 is provided at the outer edge portion of the folded plate roof 2. A work passage 5 is formed between the material 50 and the parting material 60 by the mesh member 20, and the valley 6 of the folded plate roof 2 with the drainage openings left at the upper and lower ends of the valley 6 of the folded plate roof 2. And a closing plate 70 that restricts the inflow of air into the valley 6 below the planting mat 30 is provided. However, the work path 5 can be formed in an arbitrary layout, and the parting material 60 is omitted and the parting material 60 is omitted from the roof greening facility 1 at the site where the roof greening facility 1 is arranged up to the outer edge of the folded plate roof 2. You may arrange | position to the outer edge of.

(Folded plate roof)
As shown in FIGS. 1, 2, 5, and 7, the folded plate roof 2 has a well-known configuration, and has a trapezoidal cross-sectional peak 4 extending from the ridge side to the eaves side at regular intervals in the left-right direction. The trough part 6 which forms the drainage passage between the adjacent peak parts 4 is formed. In order to fix the folded plate roof 2 to the main building 7 of the building, a support frame 7a formed by bending a band plate along the sectional shape of the folded plate roof 2 is fixed on the main building 7, and the support frame 7a A sword tip bolt 8 is fixed to the upper end so as to protrude upward. And when fixing the folded-plate roof 2 to the main house 7, the folded-plate roof 2 is installed in the predetermined position of a building, the sword tip bolt 8 is pierced through the folded plate roof 2, and the edge of the sword tip bolt 8 is attached. The nut 9 is fastened to the main house 7 by fastening. In addition, as the folded-plate roof 2, it is possible to employ | adopt the thing of arbitrary cross-sectional shapes, such as a cross-sectional wave shape, for example.

(Jota frame)
The joist frame 10 is, as shown in FIGS. 1 to 5, a fixed frame 11 made of a channel material fixed to the folded plate roof 2, and a main body frame 12 made of a channel material arranged to be connected to the fixed frame 11, It is arranged inside the fixed frame 11 and the main body frame 12 and has a connecting member 13 made of a channel material for connecting the two, and a sword tip bolt 8 is attached to the top of every other peak 4 of the folded plate roof 2. It is fixedly installed using. The joist frame 10 is fixed to the blade tip bolt 8 without removing the nut 9.

  The fixed frame 11 and the main body frame 12 are each composed of a substantially U-shaped channel member having the same cross-sectional size, including left and right side wall portions 10b and an upper wall portion 10c connecting the left and right side wall portions 10b. On the lower end of the side wall portion 10b, a mounting portion 10d folded inward is formed, and both frames 11 and 12 mount the mounting portion 10d near the top of the mountain portion 4 of the folded plate roof 2. The upper wall portion 10c is installed on the folded plate roof 2 in a state where the upper wall portion 10c is floated at a certain height from the top surface of the mountain portion 4 of the folded plate roof 2. Both frames 11 and 12 can be made of any material, but can be made of a relatively soft lightweight metal such as an aluminum alloy that can be screwed directly without forming screw holes. Is preferable because it can be simplified.

  An elongated attachment hole 14 is formed in the middle of the fixed frame 11 so that the sword bolt 8 can be inserted therethrough in the inclination direction of the roof, so that the attachment position of the fixed frame 11 can be adjusted in the inclination direction of the roof. . The length of the fixed frame 11 can be set to any length as long as the sword tip bolt 8 and the connecting member 13 can be fixed to the fixed frame 11. For example, a length of 150 to 250 mm can be adopted. The length of the main body frame 12 is set as long as possible within a range that does not impair handling properties and transportability. For example, a length of 1500 to 2500 mm can be suitably employed.

  When the joist frame 10 is fixed to the folded plate roof 2, the fixed frame 11 is installed at the top of the mountain portion 4 of the folded plate roof 2 so that the sword bolt 8 is inserted into the mounting hole 14 of the fixed frame 11. In this state, after attaching the seat plate 15 to the sword tip bolt 8, the nut 16 is fastened, the connecting member 13 is attached to the inside of the fixed frame 11 and the main body frame 12, and one end of the main body frame 12 is attached to the fixed frame 11. The frame 11 and 12 are fixed to the connecting member 13 with screws 17 in a state of being in contact with the end of the plate, so that the mounting portion 10d is fixed to the folded-plate roof 2 in a state where the mounting portion 10d is pressed near the top of the mountain portion 4. is set up. However, after fixing the connecting member 13 to the fixed frame 11 in advance and fixing it to the folded plate roof 2, the fixed frame 11 may be fixed to the connecting member 13. In addition, since the arrangement position of the sword tip bolt 8 varies depending on the building, the main frame 12 is cut on-site as necessary, and the length of the joist frame 10 is determined according to the distance between the adjacent sword tip bolts 8. Will be adjusted.

  Since the joist frame 10 is divided into the fixed frame 11, the main body frame 12, and the connecting member 13, the number of parts increases. Since the height can be easily adjusted, the workability of construction work can be improved.

  However, the fixing frame 11 may be omitted, and the main body frames 12 may be directly connected to each other by the connecting member 13, and the mounting hole 14 may be formed on the main body frame 12 on the spot. In addition, as the fixed frame 11 and the main body frame 12, as long as it has a substantially flat mounting surface 10a on the upper surface and can be stably installed in contact with the area of the top of the mountain portion 4 of the folded plate roof 2, Arbitrary cross-sectional shapes can be employed, and for example, a substantially square-shaped member having a closed cross-sectional shape may be used. Further, the joist frame 10 may be provided at the top of each mountain portion 4, or may be provided at the top of every plurality of mountain portions 4 when sufficient mounting strength for the folded plate roof 2 can be secured. Further, a spacer member (not shown) made of a rib-like member or a plate-like member having a thickness suitable for the space between the main body frame 12 and the top of the folded plate roof 2 may be provided inside the main body frame 12 at regular intervals. Good. In this case, since the downward load acting on the main body frame 12 can be received by the folded plate roof 2 via the spacer member, a light and inexpensive one having a thin plate thickness is adopted as the main body frame 12, The problem that the main body frame 12 bends or deforms due to the load of the operator or the like can be prevented.

(Reticulated member)
As the mesh member 20, a metal wire knitted or woven material or an expanded metal can be suitably used. The shape of the opening 21 of the mesh member 20 can be set to an arbitrary shape such as a square, a rectangle, a rhombus, or a tortoiseshell shape. However, when using a planting fixture 40 to be described later, the opening 21 has a rhombus mesh member 20. It is preferable to use it.

  As shown in FIGS. 1, 2, and 6, the mesh member 20 is laid from the ridge to the eaves on the mounting surface 10 a over a plurality of adjacent joist frames 10, and on the mesh member 20 on the upper side of the joist frame 10. The fixing plate 22 is set at appropriate intervals in the length direction, and the fixing plate 22 is fixed to the joist frame 10 with screws 23, so that the mesh member 20 is sandwiched between the fixing plate 22 and the joist frame 10. It is fixed to the frame 10. However, when the roof greening facility 1 is provided on a part of the folded plate roof 2, the joist frame 10 and the net-like member 20 may be provided in a region where the roof greening facility 1 is constructed.

(Planting mat)
As shown in FIGS. 3 and 10, the planting mat 30 is formed by laminating a drainage mat 31, a root shielding sheet 32, and a planting base mat 33 in order from the lower side.
The drainage mat 31 is a water-permeable member formed by molding a fiber material into a three-dimensional network mat, and its compressive strength is set to such an extent that it does not buckle even when the operator rides on it, for example, 40 kN / m ² or more. Has been. The thickness of the drainage mat can be arbitrarily set, but it is preferably set to 20 to 50 mm in consideration of handling properties. Moreover, what was shape | molded in the square shape and what was shape | molded in the elongate strip | belt shape can be employ | adopted suitably. The drainage mat 31 can be arbitrarily set as long as it has excellent environmental resistance. For example, synthetic resin fibers such as polyethylene, polypropylene, and polyethylene terephthalate, natural fibers, and fine metal wires can be suitably used. In particular, synthetic resin fibers made of polypropylene are suitable because they have excellent properties such as acid resistance, alkali resistance, and microbial resistance.

  The root shielding sheet 32 allows the water from the planting base mat 33 to pass through but prevents the passage of vegetation roots, and is a chemical whose roots dislikes woven fabrics and non-woven fabrics made of synthetic resin fibers or natural fibers and having excellent water permeability. Is impregnated. This root shield sheet 32 can be of any thickness, but in order to make the thickness of the planting mat 30 as thin and light as possible, it should be made as thin as possible within a range that can prevent the passage of vegetation roots. For example, the thickness is set to 2 mm or less. As the root shield sheet 32, for example, a general-purpose sheet having a width of 1.0 to 2.0 m is used, and the adjacent root shield sheet 32 is constructed by overlapping its side edges by, for example, 30 cm.

  The planting base mat 33 has a well-known configuration, and includes a water-permeable base mat 34 and a three-dimensional network-structured soil holding part 35 made of a fiber material fixed on the base mat 34. The mat 34 is composed of a mat having a thickness of 1.5 to 10 mm made of polyethylene, polypropylene, or the like, and the soil holding part 35 is composed of a fiber material such as polyethylene or polypropylene.

Since such a planting base mat 33 is 400 to 2000 g / m ² and lightweight, for example, a roll of the planting base mat 33 having a width of 1 to 2 m is transferred onto the roof and then onto the roof. After the construction, the seedlings of vegetation can be planted and constructed after spreading the soil on the soil holding unit 35. For this reason, compared with the planting mat 30 which planted the vegetation previously, it becomes what was excellent in transportability, transferability on a roof, and workability. However, until the vegetation grows and the soil is retained by the roots, in order to prevent the vegetation seedlings and soil from being washed away, a paste-like liquid is sprayed on the soil and the surface of the soil is properly solidified. Also good. Moreover, as long as the planting base mat 33 can grow vegetation, another known configuration may be adopted.

  As the vegetation, vegetation that is relatively resistant to drying is suitable, such as sedums belonging to the family Aceraceae such as album, tight gome, reflexum, malba mannen, mexican mannen, and lawn.

  However, instead of the planting mat 30, the drainage mat 31 and the root shielding sheet 32 are sequentially laid on the net-like member 20, and then a planting layer with embankment is provided thereon. It can also be configured to plant various types of vegetation. In particular, as will be described later, when the mesh member 20 is arranged on a substantially horizontal plane on the folded plate roof, there is almost no runoff of the embankment due to the gradient, and thus such a configuration can be suitably employed.

(Partition material)
Next, the partition member 50 that holds the outer edge of the planting mat 30 will be described.
As shown in FIGS. 1 and 2, the partition member 50 is formed by bending a metal strip of a certain length, such as a stainless steel plate, an iron plate, or an aluminum plate, by about 90 ° in the middle in the width direction. It is formed in an L shape, and includes a partition portion 51 that is in contact with the outer edge of the planting mat 30, and a fixing portion 52 that extends from the lower end of the partition portion 51 along the mesh member 20. The partition portion 51 is brought into contact with the outer edge of the planting mat 30 and the fixing portion 52 is fixed to the joist frame 10 with screws 53 so as to be fixed to the folded plate roof 2. The partition member 50 may be provided over the entire outer edge of the planting mat 30, but may be provided at appropriate intervals on the outer edge of the planting mat 30.

(Parting material)
Next, the parting material 60 which covers the outer edge part of the folded-plate roof 2 is demonstrated.
As shown in FIGS. 1, 2, 7, and 8, the parting material 60 is a metal plate such as a stainless steel plate, an iron plate, or an aluminum plate, and is about 90 ° in the middle in the width direction. It is bent and formed to have a substantially L-shaped cross section, and includes a fixing portion 61 for the folded plate roof 2 and a parting portion 62 extending upward from one side of the fixing portion 61. The parting part 62 is arranged along the outer edge of the folded-plate roof 2 toward the inner side of the folding plate, and the fixing part 61 is fixed to the joist frame 10 with screws 62b, thereby being continuously arranged along the outer edge of the folded-plate roof 2 Has been.

  A folding portion 62a is formed at the upper end of the parting part 62, and is configured to improve the strength of the parting material 60 and improve safety when handling the parting material 60. As the parting material 60, for example, a material having a length of 2 m is adopted, which is connected using a serial connection member 63 and a corner connection member 64 having a substantially L-shaped cross section, and is continuously formed along the outer edge of the folded roof 2. Will also be provided. Specifically, when the parting materials 60 are connected in series, a metal strip of a certain length, such as a stainless steel plate, an iron plate, or an aluminum plate, is bent about 90 ° in the middle in the width direction. Using the serial connection member 63 having a substantially L-shaped cross section, the serial connection member 63 is inserted into the folded portion 62a of the parting material 60 in the state where the upper end portion of the serial connection member 63 is inserted. It arrange | positions along an inner side and connects the serial connection member 63 to the partition part 51 using fixing tools, such as the volt | bolt 65, the nut 66, and a rivet. Further, when the parting material 60 is connected in an L shape, a metal strip such as a stainless steel plate or an iron plate is bent at about 90 ° in the middle in the width direction to have a substantially L-shaped cross section. The corner connecting member 64 formed in a shape and further bent in an L shape in plan view at the middle in the length direction is inserted into the folded portion 62a of the parting material 60 at the upper end portion of the corner connecting member 64. In this state, the corner connecting member 64 is disposed inside the adjacent parting material 60, and the corner connecting member 64 is connected to the partition portion 51 using a fixing device such as a bolt 67, a nut 68, and a rivet.

  However, the partition material 50 may be omitted, and the parting material 60 may be configured to hold the outer edge of the planting mat 30. Moreover, since the parting material 60 itself is for improving the external appearance of the roof, it can be omitted when the partition member 50 is inside.

(Closing plate)
As shown in FIGS. 1 and 2, the upper and lower end portions of the folded plate roof 2 are provided with closing plates 70 that close the trough 6 with the bottom side of the trough 6 open. The closing plate 70 is made of a metal plate such as a stainless steel plate, an iron plate, or an aluminum plate, or a synthetic resin molded body, and connects a trapezoidal closing portion 71 that closes the valley portion 6 and a plurality of adjacent closing portions 71. The connecting portion 72 is attached to the joist frame 10 by fixing the connecting portion 72 on the joist frame 10.
Providing such a closing plate 70 can suppress the inflow of wind into the valley 6 and prevent the planting mat 30 from drying to promote the growth of vegetation. The inflow of the wind to the part 6 is blocked, the force that pushes up the planting mat 30 from below is suppressed, and the planting mat 30 can be effectively prevented from being peeled off by the strong wind.

(Planting fixture)
Next, the planting fixture 40 for securing the planting mat 30 to the building will be described.
As shown in FIGS. 9 to 12, the planting fixture 40 includes a lower base plate 41 that can be inserted from the opening 21 of the mesh member 20 to the lower side of the mesh member 20, and an upper side that is disposed above the mesh member 20. A base plate 42, a column 43 made of a bolt member, a first nut member 44 screwed to the column 43 on the upper side of the upper base plate 42, and an intermediate plate 45 mounted on the middle of the column 43 so as to be vertically movable. The second nut member 46 screwed to the support column 43 on the upper side of the intermediate plate 45, the top plate 47 attached to the upper end portion of the support column 43 so as to be vertically movable, and the cap nut screwed to the end portion of the support column 43 48. The base plates 41 and 42 correspond to fixing means. Examples of the fixing means include a type that clamps the mesh member 20 and a hook that can be hooked on the mesh member 20 from the upper side of the mesh member 20. Any structure that can be attached to the mesh member 20 can be used.

  The planting fixture 40 is fixed to the mesh member 20 by sandwiching the mesh member 20 between the lower base plate 41 and the upper base plate 42. Moreover, in this planting fixing metal fitting 40, the drainage mat 31 is fixedly held on the building and held adjacent by sandwiching the side edges of the drainage mat 31 adjacent between the upper base plate 42 and the intermediate plate 45 at set intervals. The drainage mat 31 is connected, the root shielding sheet 32 is sandwiched between the intermediate plate 45 and the top plate 47, and the side edge of the adjacent planting base mat 33 is sandwiched, so that the root shielding sheet 32 and the planting base are sandwiched. While the mat 33 is fixedly held on the building, the adjacent planting base mats 33 are connected. However, in the case where a plurality of drain mats 31 are arranged adjacent to the left and right below the one planting base mat 33, a short column is used instead of the column 43 of the planting fixture 40 and the top plate 47 is used. It may be omitted and only the drainage mat 31 may be sandwiched between the upper base plate 42 and the intermediate plate 45.

The upper base plate 42, the lower base plate 41, the intermediate plate 45, and the top plate 47 are manufactured by press-molding a metal plate such as a flat stainless steel plate or an iron plate. However, it can also be made of a synthetic resin material.
If the upper base plate 42 has a size that does not drop out of the opening 21 even if the column 43 is moved to an arbitrary position of the opening 21 of the mesh member 20, the length of one side is one side of the mesh member 20 constituting the opening 21. Arbitrary shapes and sizes such as a square shape larger than the length L and a circular shape having a diameter larger than the length L of one side constituting the opening 21 can be adopted.

The lower base plate 41 can be inserted into the lower side of the mesh member 20 in a state where the support 43 is mounted, and is arranged in an arbitrary position in the opening 21 of the mesh member 20 in a state of being horizontally disposed below the mesh member 20. The size and the shape are set such that the upward movement of the mesh member 20 is restricted even if the column 43 is moved to the position. Specifically, as shown in FIG. 12, the length L1 from one end of the long side of the lower base plate 41 to the peripheral edge on the opposite side of the column 43 is the diagonal line of the shorter opening 21 of the mesh member 20. It is comprised with the rectangular plate-shaped member set to less than length L3 of the longer diagonal line more than length L2.
When such a lower base plate 41 and an upper base plate 42 are used, the column 43 is moved to an arbitrary position of the opening 21 of the mesh member 20 with the lower base plate 41 inserted below the mesh member 20. Even if it does, since the net-like member 20 can be clamped between the lower base plate 41 and the upper base plate 42, the construction of the planting fixture 40 on the net-like member 20 becomes easy.

  Insertion holes 45a through which the support columns 43 are inserted are formed at the center of the intermediate plate 45, and first engagement claws 45b inserted into the drainage mat 31 are bent downward at the four corners of the intermediate plate 45 at the four corners of the intermediate plate 45. The second engaging claw 45c is formed by cutting and raising in the vicinity of the four corners of the intermediate plate 45. The intermediate plate 45 has the first engaging claw 45b and the second engaging claw 45c on the drainage mat 31. It is pierced and engaged with the drainage mat 31. The first engagement claw 45b is formed in an arrow shape by cutting off both ends of the base portion, and is configured so that the first engagement claw 45b is difficult to come out while being stabbed into the drainage mat 31. However, the intermediate plate 45 may be omitted.

  The top plate 47 is formed in a substantially cross shape so as to minimize the area of the top plate 47 so as not to inhibit the growth of the planting while pressing the four adjacent planting base mats 33. An insertion hole 47a through which the support column 43 is inserted is formed in the center portion of the top plate 47, and engaging claws 47c that extend downward and are inserted into the planting base mat 33 are cut and raised in the four arm portions 47b of the top plate 47. The top plate 47 is engaged with the planting base mat 33 by inserting the engaging claws 47 c into the planting base mat 33.

  In addition, although it is preferable to comprise the net-like member 20, the partition material 50, the parting material 60, the member which comprises the planting fixing metal fitting 40, and the closing board 70, it is preferable to comprise with the material excellent in corrosion resistance, The material which is easy to rust like iron In the case of comprising, the rust prevention treatment such as plating is performed after the molding.
