Description

  The present invention relates to a greening structure of a roof for the purpose of alleviating the heat island phenomenon in an urban area, and more particularly to a greening structure of a simple roof such as a platform roof of a station building.

  Simple roofs in urban areas, especially light and simple roofs (slate roofs, folded plate roofs, other metal roofs, non-metal roofs, etc.) installed on platforms, etc., are required to form landscapes with the surrounding high-rise buildings. Not only is it a place where people gather, but in addition to the landscape, greening is planned for the purpose of restoring the natural environment through greening, improving the landscape and mitigating the heat island phenomenon, purifying the atmosphere, and creating an amenity space. Should.

Therefore, many attempts have been made to plant lawn or the like on the rooftop of a building to turn it green, reduce the carbon dioxide (CO ₂ ) emission by its heat insulating action, and alleviate the heat island phenomenon in urban areas. However, when greening simple lightweight roofs installed on platforms, etc., it is necessary to prevent excessive loads on the roof. Measures such as special reinforcement and waterproofing are required.

  Therefore, conventionally, a planting pack is used to construct a greening system that grows in valleys or the like of origami roofs (see Patent Document 1). Related to greening structure of folded plate roof (see Patent Document 2). A roof greening system using vine plants (see Patent Document 3). A greening device in which a support that supports a planter is fixed to a wall portion that is erected substantially vertically, such as a roof rising portion, via a coupling device (see Patent Document 4). A greening structure comprising a roof-like cover installed in an open space, a holding means such as a pillar for holding the cover in the space, and a greening facility installed on the cover (see Patent Document 5). ) Etc. have been proposed.

  However, since all of the above prior arts provide a planting base on the entire roof and green it, it is necessary to install a waterproof layer and a protective layer on the entire roof surface. In addition, it is necessary to take measures against the problem of increased costs, sediment loss and rainwater drainage during rainfall. In addition, there is a problem that maintenance such as fertilization and watering is difficult. The need for rooftop greening in buildings is further increasing, especially on the simple roof of the platform of the station building, because there are problems such as load restrictions and maintenance of planting bases. A solution to make maintenance easier was envied.

  In view of the above-described problems of the conventional technology, the present invention provides a simple roof greening structure such as a platform that can solve the problem of excess load caused by greening, can be economically constructed, and can save labor for maintenance. It is intended to do.

  Therefore, the greening structure of a simple roof such as a platform according to the present invention has a rooter sheet and a protective mat laid, a planter that contains planting soil and planted vines, and is fixed to the bottom of the roof. The first feature is that it consists of a grating that mounts and fixes the planter and also serves as a maintenance passage, a net for propagating and growing vine plants on the roof surface, a drainage basin, and a drainage drain. To do. A second feature is that the outer end of the roof is provided with a sag that is wound inwardly upward. Furthermore, the third feature is that humus customer soil (peat) is used as growing soil.

The present invention has the following excellent effects.
(1) Lightweight simple roofs such as station building platforms can be greened.
(2) Construction, handling and maintenance are easy.
(3) Since peat (roof soil: trade name: made by Masaki Envec Co., Ltd.) is used as the growing soil, water retention, drainage and fertilizer retention

It is a front view which shows the greening structure of the platform roof which concerns on this invention. It is a top view of FIG. It is a top view of the roof which shows the example of arrangement | positioning of the irrigation pipe. It is a principal part expanded sectional view of FIG. It is a principal part expanded sectional view which shows the inside of a planter.

  Embodiments according to the present invention will be described below with reference to examples shown in the drawings. 1 is a front view showing a greening structure of a platform roof according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a plan view of a roof showing an arrangement example of irrigation pipes, and FIG. 4 is a main part of FIG. FIG. 5 is an enlarged cross-sectional view showing the inside of the planter.

  FIG. 1 is a cross-sectional view showing the entire structure of a simple roof 1 of a platform according to the present invention. A planter 2 in which vines 3 are planted as a planting part is hung over the bottom of a pair of folded roof boards 4. Mounted and fixed on the attached grating 5, a drainage basin 6 is provided below the drainage pipe 6, and a drainage drain pipe 7 for allowing rainwater and the like to flow down is provided inside the column 8 standing on the platform 10. Has arranged a box-shaped flower bed 9. In addition, as shown in FIG. 2, the irrigation pipe 18 is internally provided in the grating 5 and is branched to each planter 2. In addition, as shown in FIG. 3, if the irrigation pipe 18 is formed in a loop shape with a certain length, and this is set as one unit, a plurality of arrangements are made according to the length of the roof, so that the construction becomes simple. .

  That is, a plurality of planters 2 are arranged at predetermined intervals in the left and right rows along the longitudinal direction of the roof 1 in the vicinity of the top 8 of the simple roof 4 that is usually formed of a slate material and has the most load resistance. And the net | network 11 is laid in order to propagate and grow the vine plant 3 on the roof 1 surface. One end of the net 11 is fixed to the upper end of the planter 2 and the other end (the edge of the roof 1) by pins 11a. The grating 5 is fixed to the left and right end portions of the grating 5 in contact with the surface of the roof 4 and the lower end portion of the support bundle 12 through a rubber pad 13 as a cushioning material in order to function as a maintenance passage where an operator walks. Is done. Moreover, in order to prevent the grown vine plant 3 from hanging down from the roof plate 4 to the home 10 at both side edges of the roof 1, a hanging plate 4a formed in an inner winding is attached.

  As shown in FIGS. 4 and 5, the planter 2 is securely fastened to the grating 5 with bolts and nuts at the left and right lower end walls via stoppers 14 made of angle steel. Inside the planter 2, a root-resistant sheet 15 and a protective mat 16 are laid and stacked, the planting soil 17 is accommodated, and the vine plant 3 is planted. As the planting soil 17, it is preferable to use lightweight humus soil (peat).

  As humus soil, peat that has undergone special chemical treatment and microbial treatment is used. In chemical treatment, harmful substances in peat are removed, and in microbial treatment, microbial solvent is mixed. The humus soil has a high water absorption rate and ion exchange rate, is excellent in water retention and fertilizer retention, and has a buffering effect on acid bases. In addition, the soil properties of humus soil are difficult to denature for a long time, and the cultivation floor is not hardened. Therefore, the rooting of a plant becomes favorable and it can ensure the water retention power suitable for cultivation, water permeability, fertilization property, and air permeability favorably. In this example, roof soil (trade name: manufactured by Masaki Envec Co., Ltd.) was used as humus soil.

  As described above, when the planter 2 is arranged on the left and right in the vicinity of the support 8 having the most load bearing capacity of the light and simple roof 1 and the seedlings of the vine plant 3 are planted, the vine plant 3 becomes the roof 4 on both sides. Following the slanted surface, the net 11 is spread over the entire roof and greened. The grating 5 used as a main passage for maintenance can be attached and detached by a bolted joint type, and a branch passage made of grating for the planting situation and management inspection of each part can be appropriately arranged on the inclined part. Management work becomes easy. Of course, it goes without saying that the structure of the present invention can be applied not only to the platform roof but also to an existing lightweight and simple roof.

  Needless to say, the present invention is not limited to the above-described embodiments, and can be appropriately changed within the scope of the gist of the present invention. For example, the size and number of planters installed, and the varieties of vine plants to be planted are arbitrary.
