Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roof greening facility for a folded-plate roof suitable for construction on the folded-plate roof.
[0002]
[Prior art]
In recent years, for the purpose of improving the urban environment against global warming and the like, rooftop greening equipment that can be installed by effectively utilizing the rooftop space of the rooftop of a building or condominium or a house has been spreading.
As such a rooftop greening facility, a rooftop garden type and a thin greenhouse type have been put into practical use, and in particular, a thin green roof type of a thin rooftop greenery facility is remarkably compared with a rooftop garden type rooftop greenery facility. It is lightweight, can be easily applied to existing buildings, can maintain good drainage and can suppress temperature changes on the roof surface of the building, so that it can improve the durability of the building, It has attracted attention because of its excellent advantages such as increased heat and heat retention and reduced utility costs.
[0003]
As the thin-layer roof greening equipment, a waterproof sheet is laid on a building, and a thin-layer greening laminate is formed by stacking a drainage mat, a root shielding sheet, and a planting mat in this order from the bottom. Things have been put to practical use. And, by using a mat made by planting vegetation, mainly sedums with excellent drought resistance, in a thin cultivated soil, it is possible to set a low water holding capacity for the thin layer greening laminate, It is configured to reduce the weight of the thin greenery laminate and to prevent a decrease in the durability of the building due to a reduction in temperature change and blocking of ultraviolet rays.
[0004]
On the other hand, various folding roof greening facilities that can be constructed on a folding roof such as a factory have been proposed. For example, Japanese Patent Application Laid-Open No. 2000-166375 describes a folded plate roof greening facility in which a plant vegetation material is set in a valley of a folded plate roof and a plant is planted in the plant vegetation material. According to this publication, as a plant vegetation material, for example, mineral fibers such as rock wool and ceramic wool, or recycled materials such as coconut shell, bark, or car shredder dust, and the like are formed into a predetermined shape. It has a water retention property manufactured by the above method.
[0005]
JP-A-2002-95348 describes a roof greening 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.
[0006]
[Problems to be solved by the invention]
By the way, although the thin-layer greening equipment has been performed to some extent, the actual situation is that the roof greening equipment of the folded plate roof has not yet been sufficiently studied.
For example, in the roof greening equipment described in Japanese Patent Application Laid-Open No. 2000-166375, although the number of component parts is small and the construction can be performed at low cost, the cultivation soil is set in the valley of the folded plate roof up to the middle part in the depth direction. Therefore, drainage of rainwater is not smooth, and if the amount of rainwater increases, the soil will be washed away with the rainwater, and the roof strength when the soil becomes heavy including the rainwater will not be able to secure sufficient roof strength, and the greening area will be reduced. There is a problem that it cannot be set to a large value, and that the folded-plate roof is easily damaged because wet soil is constantly in contact with the folded-plate roof.
[0007]
Further, in the roof greening facility described in JP-A-2002-95348, since the planting device is disposed on the heat insulating material from the non-permeable member, the folding by the wet cultivation coming into direct contact with the folded plate roof. Although the durability of the flat roof can be prevented from decreasing, the drainage structure of the folded roof cannot be used as it is, which complicates the drainage structure and ensures sufficient bending strength of the heat insulating material at the position corresponding to the valley. However, there is a problem that the heat insulating material is deformed into the valley and cannot be returned to the original position when the worker gets on the heat insulating material for construction of the planting device or due to aging.
[0008]
An object of the present invention is to provide a roof greening facility for a folded-plate roof that can easily and with sufficient strength planting mats of a thin-layer roof greening facility that has a proven track record in roof greening.
[0009]
Means for Solving the Problems and Their Functions
The roof greening equipment 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 fixed roofs installed along the length direction on the top of the mountain of the folded-plate roof. , A substantially flat net-like member laid and fixed over the plurality of joist frames, and a planting layer provided on the net-like member.
[0010]
In this roof greening equipment, the mesh member is fixedly installed on the folded roof with a joist frame interposed, and a planting layer is provided on it, so even if the slope of the roof is relatively large, the construction work is complicated. The planting layer can be stably installed on the folded-plate roof while preventing the occurrence of the planting layer.
[0011]
In other words, it is possible to fix and install the net-like member directly on the folded-plate roof using a sword bolt or the like protruding upward from the folded-plate roof, and to provide a planting layer thereon, For example, when the steepness is 1/50 or more, the planting layer may slide down together with the net-like member, and if a new fixing point is provided in addition to the sword bolt to prevent this sliding down, the number of parts increases and The construction work becomes complicated.
[0012]
On the other hand, in the present invention, the joist frame is fixed to the top of the crest of the folded plate roof, so that a sufficient contact area between the joist frame and the folded plate roof is secured, and the sliding direction is reduced by frictional resistance with the folded plate roof. , The shear load acting on the point bolts can be reduced, and the joist frame can be securely fixed without increasing the number of fixing points even on a folded-plate roof with a relatively large slope. Moreover, 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 the mounting strength of the mesh member to the joist frame is sufficiently secured. it can.
[0013]
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. The planting layer can be securely fixed to the folded-plate roof with only the sword-point bolts for fixing the folded-plate roof while preventing the work from being complicated. In addition, even when applied to a folded plate roof fixed with goby, a sufficient contact area between the joist frame and the folded plate roof can be secured, as with a folded plate roof fixed with sword bolts. The net member as a material can be firmly fixed to the folded plate roof.
[0014]
In addition, since the strength of the mesh member at the position corresponding to the valley of the folded plate roof can be sufficiently secured by using a metal member as the mesh member, for example, when the planting layer is constructed, the mesh member may be used. Deformation of the mesh member due to deformation or aging can be reliably prevented. In this manner, a lightweight and stable substantially flat installation surface can be formed on the folded plate roof by the mesh member, so that the planting layer can be stably constructed.
[0015]
Moreover, when such a mesh member is used, the rainwater on the planting layer can be drained to the valley of the folded-plate roof as it is, and the rainwater can be drained by utilizing the drainage structure of the folded-plate roof. This makes it possible to realize roof greening equipment with excellent drainage properties. In addition, because the planting layer itself does not directly contact the folded-plate roof, corrosion of the folded-plate roof can be prevented, and the durability of the folded-plate roof can be prevented from deteriorating due to sunlight. Can be improved.
[0016]
Here, a planting mat may be laid on the mesh member as the planting layer, and the planting 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 by the planting fixture provided at an arbitrary position of the mesh member, and the mounting strength of the planting layer to the mesh member can be sufficiently secured. The whole roof greening equipment can be firmly fixed to the folded roof. In addition, as described above, a lightweight and stable substantially flat installation surface can be formed on the folded plate roof by the mesh member, so that a planting mat of a lightweight and simple thin-layer tree planting facility that has a proven track record in rooftop greening can be used as the mesh member. It is possible to construct on the upper side as it is.
[0017]
As the planting mat, a plant mat provided with a water-permeable drainage mat provided on a mesh member at a lower portion may be used. As the mesh member, for example, a metal expanded metal will be used.However, an expanded metal having a strength that can withstand work on a valley has a relatively large opening, so that a root shielding sheet or When the planting base mat is directly installed, these sheets and mats protrude from the openings of the mesh member, and the planting mat is damaged. For this reason, for example, a drainage mat formed by compression-molding a wire rod made of a synthetic resin is provided at the lower part of the planting mat, and is configured to receive the root shield sheet and the planting base mat. It is preferred to prevent breakage of the mat. In addition, since such a drainage mat has excellent air permeability, it is possible to secure a flow of air in a direction of climbing over a mountain, and to obtain a temperature reduction effect at a high temperature and a heat retention effect at a low temperature. Becomes possible.
[0018]
As the planting fixture, a support, fixing means for fixing the lower end of the support to the mesh member, and a top plate disposed at the upper end of the support, wherein the planting mat is pressed against the mesh member side to perform planting. What provided the top plate which fixes a mat to a net-like member may be used. When the planting fixture having such a configuration is used, the support can be fixed at an arbitrary position of the mesh member, and the planting mat can be fixed to the mesh member.
[0019]
As the fixing means, a lower base plate that can be inserted downward from the opening of the mesh member, and an upper base plate that is disposed above the mesh member, the mesh member between the upper and lower base plates via pillars. What pinches and fixes a support | pillar to a net-like member may be used. In this case, after the net-like member is laid, the support can be fixed from above, so that the planting fixture can be easily constructed. In addition, by adjusting the length of the lower base plate, the support can be fixed at an arbitrary position of the opening of the mesh member, so that the side edges of the planting mat can be easily and reliably held by the plantation fixing bracket. Becomes possible.
[0020]
As the planting mat, one provided with a drainage mat was used, and as the planting fixing bracket, an intermediate plate for pressing the drainage mat toward the mesh member side and fixing the drainage mat to the mesh member was disposed in the middle of the column. A thing may be used. When using a planting mat equipped with a drainage mat, after installation of the drainage mat, it will be necessary to ride on the drainage mat and construct a root shield sheet or vegetation base mat, etc.Because the folded plate roof has a slope, It is conceivable 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 secure the safety of the construction work of the root shield sheet, the vegetation base mat, and the like.
[0021]
The mesh member may have a rhombic opening, and the mesh member may be constructed such that the longer diagonal of the opening is substantially perpendicular to the longitudinal direction of the crest 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 mesh member having a rhombic opening such as 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 perpendicular to the longitudinal direction of the mesh member. Further, in the case of using a net-like member having such a diamond-shaped opening, for example, when the net-like member is sandwiched by fixing means composed of upper and lower base plates, a lower base plate is formed from one end on the long side to the outer peripheral end. By using a plate-shaped member whose length up to the length of the shorter diagonal line of the opening of the mesh member is less than the length of the longer diagonal line, the support can be fixed at an arbitrary position in the opening. It is preferred.
[0022]
At both upper and lower ends of the folded-plate roof, a closing plate for closing the valley may be provided with an opening left at the bottom of the valley of the folded-plate roof. With this configuration, it is possible to restrict excessive inflow of air into the valley of the folded-plate roof, prevent drying of the planting mat and promote vegetation growth, and limit blowing of wind into the valley. Therefore, it is possible to suppress a force that pushes up from below on the planting mat, and to effectively prevent the planting mat from peeling off during a storm or a strong wind.
[0023]
As the joist frame, a fixed frame made of a channel material fixed to a sword tip bolt or a goby for fixing a folded plate roof, a main body frame made of a channel material arranged in tandem with the fixed frame, and a fixed frame and a main body frame A member having a connecting member to be connected may be used. Normally, folded roofs are fixed to buildings at fixed points such as sword bolts and goby.However, in folded plate roofs fixed with sword bolts, the location of sword bolts differs depending on the building, so joist frames are used. Must be constructed on site. However, forming a mounting hole or the like in a joist frame corresponding to a sword bolt at a construction site increases a burden on the site and reduces workability. In the present invention, since the joist frame is divided into the fixed frame, the main body frame, and the connecting member, necessary processing such as a mounting hole for a sword point bolt is previously performed on the fixed frame in a factory or the like, and in the field, The joist frame can be assembled to the folded-plate roof by a simple operation of cutting the main body frame according to the pitch of the sword bolt and connecting the fixed frame and the main body frame via the connecting member. In addition, this configuration is preferable because the joist frame can be applied to a folded plate roof fixed with goby simply by replacing the fixing frame.
[0024]
A planting base mat including a base mat having water permeability and a cultivation holding part having a three-dimensional net structure made of a fibrous material fixed on the base mat may be provided above the planting mat. In this case, after the construction of the planting mat, the soil can be sprayed and held on the soil holding part of the planting base mat. It is possible to lift and plant the planting mat on the roof without using a large crane or the like.
[0025]
As the joist frame, a frame that becomes bulky toward the eaves side at an angle suitable for the inclination of the folded plate roof and can be fixedly installed on the top of the mountain of the folded plate roof so that the upper surface is substantially horizontal may be used. Good. In this case, it is possible to arrange the net-like member substantially horizontally, and it is needless to say that the above-mentioned vegetation mat can be laid on the net-like member. And flower beds and shrubs can be planted similarly to the ground.
[0026]
The same structure as the joist frame may be used, and a raising material may be fixedly installed on the joist frame having a short height, and the mounting surface of the net-like member may be arranged substantially horizontally. In order to make the upper surface of the joist frame almost horizontal, the height of the joist frame will be set so that it becomes higher toward the eaves side according to the slope of the folded plate roof, but such a joist frame is Since it is a custom-made product, the manufacturing cost is high, and when a plurality of joist frames are continuously installed along the slope of the roof, it is necessary to manufacture a plurality of types of joist frames having different heights. In the present invention, since the same structure is employed as the plurality of joist frames, it is not necessary to manufacture a plurality of types of expensive joist frames, and it is necessary to manufacture a plurality of types of raising materials. Since products can be adopted, the manufacturing cost of roof greening equipment can be reduced as a whole.
[0027]
A connecting member may be provided for connecting the joist frames arranged adjacent to each other with the valley of the folded-plate roof interposed therebetween. In this case, it is possible to prevent the joist frame from falling down due to the bulkiness of the joist frame.
[0028]

Further, the mesh member 20 is formed near the outer edge of the folded-plate roof 2, a partition member 50 is provided at the outer edge of the roof greening facility 1, and a parting member 60 is provided at the outer edge of the folded-plate roof 2. The work passage 5 is formed by the mesh member 20 between the member 50 and the parting member 60, and the valley 6 of the folded plate roof 2 is left with drain openings at both upper and lower ends of the valley 6 of the folded plate roof 2. Is closed, and a closing plate 70 for restricting the flow of air into the valley 6 below the planting mat 30 is provided. However, the work passage 5 can be formed in an arbitrary layout. In a portion where the roof greening equipment 1 is arranged up to the outer edge of the folded plate roof 2, the partition member 50 is omitted and the parting material 60 is replaced with the roof greening equipment 1. May be arranged at the outer edge of the.
[0029]
(Folded roof)
As shown in FIGS. 1, 2, 5, and 7, the folded-plate roof 2 has a well-known configuration, and has trapezoidal cross-sections 4 extending from the ridge side to the eaves side at regular intervals in the left-right direction. And a valley 6 forming a drainage passage between adjacent ridges 4. 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 cross-sectional shape of the folded-plate roof 2 is fixed on the main building 7, and the support frame 7a A sword point bolt 8 is fixed to the upper end so as to protrude upward. Then, when fixing the folded-plate roof 2 to the main house 7, the folded-plate roof 2 is installed at a predetermined position in the building, and the sword-point bolt 8 is inserted into the folded-plate roof 2, and the end of the sword-point bolt 8 is inserted. The nut 9 is fixed to the purlin 7 by fastening the nut 9. The folded-plate roof 2 may have an arbitrary cross-sectional shape such as a corrugated shape.
[0030]
(Joist frame)
As shown in FIGS. 1 to 5, the joist frame 10 includes a fixed frame 11 made of a channel material fixed to the folded plate roof 2, a main body frame 12 made of a channel material arranged in continuation of the fixed frame 11, It has a connecting member 13 made of a channel material that is arranged inside the fixed frame 11 and the main body frame 12 and connects the two. The sword point bolt 8 is attached to the top of every other ridge 4 of the folded plate roof 2. It is fixed and installed. Note that the joist frame 10 is fixed to the sword bolt 8 without removing the nut 9.
[0031]
The fixed frame 11 and the main body frame 12 are each formed of a substantially U-shaped channel member having the same cross-sectional size having left and right side walls 10b and an upper wall 10c connecting the left and right side walls 10b. At the lower end of the side wall portion 10b, a mounting portion 10d which is folded inward is formed, and the 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 10d is installed on the folded plate roof 2 in a state where the upper wall 10d is floated at a certain height from the top surface of the mountain portion 4 of the folded plate roof 2. The frames 11 and 12 can be made of any material. However, it is necessary to construct the frames 11 and 12 from a relatively soft lightweight metal such as an aluminum alloy, which can be directly screwed without forming a screw hole. Can be simplified.
[0032]
An elongated mounting hole 14 is formed in the middle of the fixed frame 11 in the direction of inclination of the roof, through which the sword point bolt 8 can be inserted, so that the mounting position of the fixed frame 11 can be adjusted in the direction of inclination of the roof. . The length of the fixed frame 11 can be set to any length as long as the sword bolt 8 and the connecting member 13 can be fixed to the fixed frame 11, and for example, a length of 150 to 250 mm can be adopted. The length of the main body frame 12 is set to be as long as possible within a range that does not impair handling and transportability. For example, a length of 1500 to 2500 mm can be suitably used.
[0033]
When fixing the joist frame 10 to the folded-plate roof 2, the fixed frame 11 is set on the top of the peak 4 of the folded-plate roof 2 so that the sword-point bolts 8 pass through the mounting holes 14 of the fixed frame 11. In this state, the seat plate 15 is mounted on the sword point bolt 8, the nut 16 is fastened, the connecting member 13 is mounted inside the fixed frame 11 and the main body frame 12, and one end of the main body frame 12 is fixed to the fixed frame 11. By fixing both frames 11 and 12 to the connecting member 13 with screws 17 in a state where they are in contact with the ends of the mounting portions, the mounting portion 10d is fixed to the folded plate roof 2 in a state of being pressed against the vicinity of the top of the mountain portion 4. is set up. However, the connecting member 13 may be fixed to the fixed frame 11 in advance, and this may be fixed to the folded plate roof 2 before the fixing frame 11 is fixed to the connecting member 13. Since the position of the sword bolt 8 differs depending on the building, the body frame 12 is cut at the site if necessary, and the length of the joist frame 10 is adjusted according to the distance between the adjacent sword bolts 8. Will be adjusted.
[0034]
The joist frame 10 is divided into the fixed frame 11, the main body frame 12, and the connecting member 13, so that the number of components is increased. The workability of construction work can be improved because the workability can be easily adjusted.
[0035]
However, the fixing frame 11 may be omitted, the main body frames 12 may be directly connected to each other by the connecting members 13, and the mounting holes 14 may be formed on the main body frame 12 at the site. In addition, as long as the fixed frame 11 and the main body frame 12 have a substantially flat mounting surface 10a on the upper surface and can be stably installed in contact with the area on the top of the mountain portion 4 of the folded plate roof 2, It is possible to adopt a member having an arbitrary cross-sectional shape. Further, the joist frame 10 may be provided at the top of each of the peaks 4, or may be provided at the top of a plurality of the peaks 4 if a sufficient mounting strength to the folded plate roof 2 can be ensured. Further, spacer members (not shown) made of rib-like members or plate-like members 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 at regular intervals inside the main body frame 12. Good. In this case, the downward load acting on the main body frame 12 can be received by the folded plate roof 2 via the spacer member, so that a thin, lightweight and inexpensive main body frame 12 is employed. It is possible to prevent a problem that the body frame 12 is bent or deformed by a load of an operator or the like.
[0036]
(Mesh member)
As the mesh member 20, a member formed by knitting or weaving a metal wire or an expanded metal can be suitably used. The shape of the opening 21 of the mesh member 20 can be set to any shape such as a square, a rectangle, a rhombus, and a tortoiseshell shape. However, when the planting fixture 40 described below is used, the mesh member 20 having the rhombus opening 21 is used. Preferably, it is used.
[0037]
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 is placed on the mesh member 20 above 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, and the joist is fixed. It is fixed to the frame 10. However, in the case where the roof greening facility 1 is provided in 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.
[0038]
(Planting mat)
As shown in FIG. 3 and FIG. 10, the planting mat 30 is formed by stacking a drainage mat 31, a root shield sheet 32, and a planting base mat 33 in this order from below.
The drain mat 31 is a member having water permeability formed by molding a fibrous material into a mat having a three-dimensional net structure, and has a compressive strength such that the operator does not buckle even if the worker gets on the top, for example, 40 kN / m. ² It is set above. The thickness of the drainage mat can be arbitrarily set, but is preferably set to 20 to 50 mm in consideration of handling properties. Also, those formed into a square shape or those formed into a long strip shape can be suitably adopted. The drain 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.
[0039]
The root-shielding sheet 32 allows water from the planting base mat 33 to pass through but prevents the passage of vegetation roots. Is impregnated. The root shield sheet 32 may be of any thickness. However, in order to make the thickness of the planting mat 30 as thin and light as possible, the planting mat 30 should be made as thin as possible in a range that can prevent the passage of vegetation roots. Preferably, the thickness is set to, for example, 2 mm or less. As the root shield sheet 32, a general-purpose sheet having a width of, for example, 1.0 to 2.0 m is used.
[0040]
The planting base mat 33 has a well-known configuration, and includes a base mat 34 having water permeability and a cultivation holding part 35 having a three-dimensional network structure made of a fiber material fixed on the base mat 34. The mat 34 is made of a mat made of polyethylene or polypropylene and having a thickness of 1.5 to 10 mm, and the cultivation holding part 35 is made of a fiber material such as polyethylene or polypropylene.
[0041]
Such a planting base mat 33 is 400 to 2000 g / m. ² Since it is lightweight, for example, a roll of a planting base mat 33 having a width of 1 to 2 m is transferred onto the roof, and after construction on the roof, the cultivation soil is scattered and held on the cultivation holding unit 35. Planting seedlings of vegetation before construction. For this reason, compared with the planting mat 30 in which the vegetation has been planted in advance, the transportability, the transferability on the roof, and the workability are excellent. However, until the vegetation grows and the cultivation is maintained at the roots, in order to prevent the vegetation seedlings and cultivation from being washed away, apply paste-like liquid to the cultivation and harden the surface of the cultivation appropriately. Is also good. The planting base mat 33 may have another well-known configuration as long as vegetation can grow.
[0042]
As the vegetation, vegetation which is relatively durable, such as sedums belonging to the family Crassulaceae, such as albumum, tight turtle, reflexum, malbamannen and mexicanmannen, and lawns, is suitable.
[0043]
However, instead of the planting mat 30, a drainage mat 31 and a root shield sheet 32 are sequentially laid on the mesh member 20, and then a planting layer with embankment is provided thereon. It is also possible to configure so as to plant various vegetation. In particular, as will be described later, when the net-like member 20 is arranged on a folded-plate roof in a substantially horizontal plane, there is almost no runoff of the embankment due to the gradient, so such a configuration can be suitably adopted.
[0044]
(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-made strip of a certain length such as a stainless steel plate, an iron plate, an aluminum plate or the like in the width direction at about 90 ° at an intermediate portion thereof. 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 partitioning part 51 is fixed to the folded plate roof 2 by abutting the partitioning part 51 against the outer edge of the planting mat 30 and fixing the fixing part 52 to the joist frame 10 with screws 53. The partition member 50 may be provided over the entire outer edge of the planting mat 30, or may be provided at appropriate intervals on the outer edge of the planting mat 30.
[0045]
(Parting material)
Next, the parting material 60 that covers the outer edge of the folded plate roof 2 will be described.
As shown in FIGS. 1, 2, 7, and 8, the parting material 60 is formed by forming a metal strip such as a stainless steel plate, an iron plate, or an aluminum plate at a length of about 90 ° in the middle in the width direction. It is bent to form 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.

I have.
[0065]
The main body frame 12B is configured in the same manner as the main body frame 12 in the above-described embodiment, except that the height of the side wall portion 10b is increased toward the eaves side at an angle suitable for the inclination of the folded-plate roof 2, and is increased. Have been. However, the main body frame 12B and the raising material 101 can be formed as an integral member.
[0066]
The raising material 101 is made of a general-purpose member having a square-shaped cross section or a C-shaped cross section. By using a material that is bulkier as it is disposed on the eaves side, the upper surface height of the main body frame 12B and the upper surface of the plurality of raising materials 101 are increased. The height is configured to be the same. However, it is also possible to omit the raising member 101 and to arrange the net-like member 20 so as to drop down stepwise along the upper surface of the main body frame 12B.
[0067]
The connection of the raising material 101 to the joist frame 10B may be performed by directly connecting the main body frame 12B and the raising material 101 with a bolt or the like, or a fixing plate may be provided across the side surface of the main body frame 12B and the side surface of the raising material 101.

[0069]
【The invention's effect】
According to the roof greening equipment of the folded-plate roof according to claim 1, the joist frame is fixed to the top of the mountain part of the folded-plate roof, and the net-like member is fixedly mounted on the substantially flat mounting surface of the joist frame. The mesh member as a base material of the planting layer can be reliably fixed to the folded-plate roof with only the sword-point bolts for fixing the folded-plate roof. In addition, even when applied to a folded plate roof fixed with goby, a sufficient contact area between the joist frame and the folded plate roof can be secured, as with a folded plate roof fixed with sword bolts. The net member as a material can be firmly fixed to the folded plate roof. In addition, it can be installed on an existing folded-plate roof, and processing on the folded-plate roof is unnecessary, so that it can be easily installed.
[0070]
In addition, since the rainwater on the planting layer can be drained to the valley of the folded-plate roof as it is, and the rainwater can be drained using the drainage structure of the folded-plate roof, the drainage is excellent without complicating the structure. Roof greening equipment can be realized. In addition, because the planting layer itself does not directly contact the folded-plate roof, corrosion of the folded-plate roof can be prevented, and the durability of the folded-plate roof can be prevented from deteriorating due to sunlight. Can be improved.
[0071]
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 greening facility is folded against the folded plate roof. It can be securely fixed only by the sword bolts for fixing the plate roof. In addition, since a light and stable almost flat installation surface can be formed on the folded plate roof by the mesh member, the planting mat of the lightweight and simple thin-layer greening equipment that has a proven track record in roof greening can be installed directly on the upper side of the mesh member It is possible to do.
[0072]
By using a lower part of a water-permeable drainage mat installed on a mesh member as the planting mat, it is possible to prevent damage to the root shield sheet and the planting base mat, and to overcome the mountain part. By ensuring the flow of air, it is possible to obtain a temperature reducing effect at high temperatures and a heat retaining effect at low temperatures.
[0073]
When a fixing means having a lower base plate and an upper base plate is used, after laying the net-like member, the support can be fixed from the upper side, so that the planting fixture can be easily constructed. Become. In addition, by adjusting the length of the lower base plate, the support can be fixed at an arbitrary position of the opening of the mesh member, so that the side edges of the planting mat can be easily and reliably held by the plantation fixing bracket. Becomes possible.
[0074]
Using a drainage mat with a drainage mat as a planting mat, as a planting fixture, an intermediate plate that presses the drainage mat to the mesh member side of the column and fixes the drainage mat to the mesh member When used, it is possible to sufficiently secure the safety of construction work such as root shield sheets and vegetation base mats.
[0075]
When using a thing with a diamond-shaped opening as the mesh member and constructing the mesh member so that the long diagonal of the opening is substantially perpendicular to the longitudinal direction of the ridge of the folded plate roof, at the position facing the valley of the folded plate roof It is possible to effectively receive the load when the worker gets on the vehicle. Further, when a mesh member having such a diamond-shaped opening is used, 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 appropriately set, and the opening is formed. It is preferable because the column can be fixed at an arbitrary position in the inside.
[0076]
By installing a closing plate that closes the valley with an opening at the bottom of the valley of the folded plate roof at both the upper and lower ends of the folded plate roof, excessive inflow of air into the valley of the folded plate roof is limited. To prevent the drying of the planting mat and promote the growth of vegetation, restrict the blowing of wind into the valley, suppress the force of pushing up the planting mat from below, and prevent storms It is possible to effectively prevent the plant mat from peeling off when the wind or strong winds occur.
[0077]
If a joist frame having a fixed frame, a main body frame and a connecting member is used, a necessary process such as a mounting hole for a sword point bolt is previously performed on the fixed frame in a factory or the like, and the main body frame is fixed to a sword at a site. It is possible to assemble the joist frame 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. In addition, this configuration is preferable because the joist frame can be applied to a folded plate roof fixed with goby simply by replacing the fixing frame.
[0078]
When a planting base mat having a water-permeable base mat and a three-dimensional net structure cultivation holding part made of a fibrous material fixed on the base mat is provided above the planting mat, the planting mat can be planted after the planting mat is constructed. The cultivation soil can be sprayed and held on the cultivation soil holding part of the planting base mat, so use a large crane, etc., compared to lifting the cultivated soil on the planting mat on the roof in advance. Instead, the planting mat can be lifted on the roof and constructed.
[0079]
As the joist frame, a frame that becomes bulky as it goes to the eaves side at an angle suitable for the inclination of the folded plate roof and can be fixedly installed on the top of the mountain of the folded plate roof so that the upper surface is substantially horizontal, It is possible to arrange the net-like member substantially horizontally, and it goes without saying that the above-mentioned vegetation mat can be laid on the net-like member. And shrubs can be planted on the ground.
[0080]
By using the same structure as the joist frame, fixing the raising material on the joist frame of insufficient height, and arranging the mounting surface of the mesh member substantially horizontally, the manufacturing cost of the roof greening equipment is reduced as a whole. it can.
[0081]
Providing a connecting member for connecting the joist frames arranged adjacent to each other with the valley of the folded-plate roof interposed therebetween can prevent the joist frames from falling down due to the bulkiness.
