Recently, in order to suppress the heat island phenomenon in urban areas, rooftop greening has been performed in which plants such as turf are vegetated on the rooftops of buildings. In this rooftop greening, a waterproof sheet is laid on the roof slab of the building, a waterproof layer is provided and sufficient waterproofing measures are taken, and then soil is embanked on the waterproof layer and vegetation is applied to the soil. Generally done. The soil filled here does not give a heavy weight load to the rooftop of the building, and in order to clear the weight limit of the rooftop, a special lightweight soil is used, and the thickness thereof is, for example, 10 cm or less. The weight is reduced by making it a thin layer. For this reason, the soil is easily affected by strong winds and the like, and there is a concern that the soil may rise. In particular, the roof of a building has a stronger wind than the above-ground part and is easily affected by the wind.
[0003]
Therefore, conventionally, it has been proposed to install a windproof net so as to cover the upper side of the soil and prevent the scattering of the soil by this windproof net (see Patent Document 1). The windproof net is fixed to a roof slab or the like by an anchor member fixed on the roof slab.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 to 4 show an embodiment of a structure for fixing an installation to a waterproof layer according to the present invention. 1 is a cross-sectional view of the fixing structure of the present embodiment, FIG. 2 is a perspective view of an embodiment of an anchor member used in the fixing structure of FIG. 1, and FIGS. It is explanatory drawing of the construction procedure of a fixing structure. Here, a renewal construction of a so-called waterproof layer in which a new waterproof layer 14 is provided on the existing waterproof layer 12 will be described as an example.
[0015]
As shown in FIG. 1, the fixing structure 2 has an anchor member 16 placed on the concrete 10 to be waterproofed, and a new waterproof layer 14 is provided above the anchor member 16 so as to cover the anchor member 16. The fixing member 20 for fixing the windproof net 28 and the like is installed on the waterproof layer 14. The concrete 10 is building concrete of a building such as a roof slab. The existing waterproof layer 12 is an old waterproof layer installed at the time of completion of the building. In the present embodiment, a sheet-like member 18 is interposed between the anchor member 16 and the new waterproof layer 14.
[0016]
The anchor member 16 is driven into the concrete 10 through the existing waterproof layer 12. As shown in detail in FIG. 2, the anchor member 16 includes a main body portion 16 a embedded in the concrete 10, and a flange portion 16 c formed integrally with the upper end portion of the main body portion 16 a. As shown in FIG. 2, the flange portion 16 c is formed into a disk shape and is provided so as to protrude from the surface of the concrete 10 (here, the surface of the existing waterproof layer 12). A plurality of the anchor members 16 are installed on the concrete at an appropriate interval such as 1000 mm.
[0017]
The new waterproof layer 14 is provided by laying a waterproof sheet 15 on the existing waterproof layer 12. The waterproof sheet 15 is a thin sheet-like member formed of a waterproof material such as a synthetic resin having a thickness of about 1.2 mm to 2.5 mm. The waterproof sheet 15 is bonded to the existing waterproof layer 12 and fixed on the concrete 10.
[0018]
In the present embodiment, the waterproof sheet 15 is formed of a fiber reinforced resin (FRP: Fiber Reinforced Plastics) made of a photocurable resin. Briefly describing the photocurable resin material, the change from liquid to solid by the action of light energy is called “photocuring”, and the synthetic organic material that is photocured is called photocurable resin. In general, ultraviolet rays are widely used as light that causes a curing action. Photocurable resins include photopolymerizable oligomers, photopolymerizable monomers (reactive diluents), photopolymerization initiators, photoinitiator aids, other additives, and colorants such as pigments and dyes as necessary. Consists of Examples of the photopolymerizable oligomer include acrylates such as urethane acrylate, epoxy acrylate and polyester acrylate, unsaturated polyester, and epoxy. Examples of the photopolymerizable monomer include mono- and poly-acrylate acrylates, epoxies, and the like. Examples of the photopolymerization initiator include benzoin-based, acetophacetophenone-based, peroxide-based, and onium salts.
[0019]
The waterproof sheet 15 made of such a photo-curable resin is laid on the existing waterproof layer 12 and then cured easily by being irradiated with ultraviolet rays, so that the existing waterproof layer is formed in a very short time. 12 is adhered.
[0020]
The sheet-like member 18 between the anchor member 16 and the new waterproof layer 14 has a size enough to cover the flange 16c of the anchor member 16, for example, a square having a size of about 100 mm in length × about 100 mm in width. It is formed into a shape. The sheet-like member 18 is interposed to reinforce the waterproof sheet 15 and is joined to the flange portion 16c of the anchor member 16 and the waterproof sheet 15, respectively. The sheet-like member 18 is disposed corresponding to each anchor member 16.
[0021]
Further, in the present embodiment, the sheet-like member 18 is also made of fiber reinforced resin (FRP: Fiber Reinforced Plastics) made of a photocurable resin, like the waterproof sheet 15. For this reason, in this embodiment, by irradiating with ultraviolet rays, the sheet-like member 18 can be easily cured and the construction work can be completed in a short time. Further, the sheet-like member 18 can be satisfactorily joined to the anchor member 16 and the waterproof sheet 15, and sufficient joining strength can be ensured.
[0022]
On the other hand, as shown in FIG. 1, the fixing member 20 is installed above the anchor member 16 and is erected on the waterproof sheet 15. The fixing member 20 includes a flange portion 20b that is in close contact with the waterproof sheet 15, and a rod portion 20a that protrudes upward from the center of the upper surface of the flange portion 20b. The flange portion 20b is formed to have substantially the same size as the flange portion 16c of the anchor member 16. A sheet-like member 22 is disposed on the upper surface portion of the flange portion 20 b, and the flange portion 22 b is pressed onto the waterproof sheet 15 by the sheet-like member 22. Thereby, the fixing member 20 is fixed on the waterproof sheet 15.
[0023]
In the present embodiment, the sheet-like member 22 is also made of fiber reinforced resin (FRP: Fiber Reinforced Plastics) made of a photocurable resin, like the sheet-like member 18 and the waterproof sheet 15. For this reason, the sheet-like member 22 can be joined to the waterproof sheet 15 simply by placing the sheet-like member 22 on the upper side of the flange portion 20b of the fixing member 20 and irradiating it with ultraviolet rays. It can be finished in time.
[0024]
A soil 24 is filled on the waterproof sheet 15, and plants 26 such as turf are vegetated on the soil 24 to form a greening base 30. And as shown in the figure, the upper end part 20c of the fixing member 20 protrudes on the surface of the soil 24, and the upper end part 20c of the soil 24 installed so as to cover the upper side of the soil 24 A windproof net 28 or the like for preventing scattering or the like is connected.
[0025]
Since the anchor member 16 is installed below the fixing member 20 with the waterproof sheet 15 therebetween, even if a large tensile force as shown by the arrow A in the figure acts on the fixing member 20 from the windproof net 28 or the like. This force is transmitted from the anchor member 16 to the concrete 10 via the waterproof sheet 15. For this reason, a sufficient reaction force is obtained from the concrete 10, and the tensile force can be resisted without peeling from the waterproof sheet 15.
[0026]
Although not shown here, a water-impervious sheet, a root-proof sheet, or the like is provided between the soil 24 and the waterproof sheet 15, and the soil 24 is supplied and drained to the entire soil 24 inside the soil 24. In addition, various components necessary for forming the greening base may be provided, such as a water guide sheet, a drainage sheet, a water supply pipe, and a drainage pipe.
[0027]
However, in this embodiment, since the waterproof sheet 15 is formed of fiber reinforced resin, the root-proof sheet may be omitted. This is because the waterproof sheet 15 formed of a fiber reinforced resin has a considerable strength and is excellent in wear resistance, and thus is not easily damaged by the roots of plants and functions sufficiently as a root-proof sheet. . Thereby, the construction effort can be reduced and the construction cost can be reduced. In addition, the thickness of the soil 24 can be reduced, and a lightweight greening base can be formed to reduce the burden on structures such as buildings.
[0028]
Next, the construction procedure of this fixing structure will be described. When constructing this fixing structure, first, as shown in FIG. 3A, an anchor member 16 is driven into the concrete 10 and installed. Here, the anchor member 16 is driven from above the existing waterproof layer 12 installed on the concrete 10. Then, the flange portion 16 c of the anchor member 16 is exposed on the surface of the existing waterproof layer 12.
[0029]
Next, as shown in FIG. 3B, the sheet-like member 18 is installed on the existing waterproof layer 12 so as to cover the upper side of the flange portion 16 c of the anchor member 16. In the present embodiment, since the sheet-like member 18 is formed of a photocurable resin, the sheet-like member 18 is cured by irradiating the installed sheet-like member 18 with ultraviolet rays, and the flange portion 16c of the anchor member 16 and It joins to the existing waterproof layer 12.
[0030]
Next, as shown in FIG. 3C, a waterproof sheet 15 is laid on the existing waterproof layer 12 so as to cover the anchor member 16 and the sheet-like member 18, thereby providing a new waterproof layer 14. Since the waterproof sheet 15 is also formed of a photo-curable resin in the present embodiment, after installation, the waterproof sheet 15 is irradiated with ultraviolet rays to cure the waterproof sheet 15 to provide the existing waterproof layer 12 and sheet. It joins to the member 18.
[0031]
After providing a new waterproof layer 14 on the existing waterproof layer 12 on the concrete 10 in this way, as shown in FIG. 4 (d), the fixing member 20 is installed on the waterproof sheet 15, The fixing member 20 is fixed by laying the sheet-like member 22 so as to cover the flange portion 20b. Also in this embodiment, since the sheet-like member 22 is formed of a photocurable resin, the sheet-like member 18 is joined to the waterproof sheet 15 only by irradiating the installed sheet-like member 18 with ultraviolet rays. The fixing member 20 can be easily installed.
[0032]
After the installation of the fixing member 20, the soil 24 is embanked and the plant 26 is vegetated to form a greening base above the waterproof sheet 15 as shown in FIG.
[0033]
As described above, according to the present embodiment, the anchor member 16 is fixed to the concrete 10, the waterproof sheet 15 is installed over the anchor member 16 so as to cover the anchor member 16, and the anchor member 16 is installed on the waterproof sheet 15. Since the fixing member is installed above the position corresponding to the position, even if a large tensile force acts on the fixing member 20 from the windproof net 28 or the like connected thereto, the fixing member is interposed through the waterproof sheet 15. Since the anchor member 16 is fixed to the concrete 10, a sufficient reaction force can be obtained from the concrete 10, and peeling from the waterproof sheet 15 can be prevented.
[0034]
Moreover, in this embodiment, since the waterproof sheet 15 and the sheet-like members 18 and 22 are formed of a photo-curing resin, they can be easily cured by irradiating with ultraviolet rays. It can be done very quickly and easily. In particular, the fixing member 20 can be easily installed by fixing the fixing member 20 with the sheet-like member 22.
[0035]
Moreover, in this embodiment, since the patch-like sheet-like member 18 is interposed between the anchor member 16 and the waterproof sheet 15, the bonding strength between the anchor member 16 and the waterproof sheet 15 can be improved. The fixing member 20 can be fixed more reliably.
[0036]
In the present embodiment, the waterproof sheet 15 and the sheet-like members 18 and 22 are formed of a photocurable resin, but the present invention is not limited thereto, and may be formed of various known resin materials. Moreover, you may form with other raw materials besides resin. In particular, the sheet-like members 18 and 22 are not necessarily formed of a waterproof material because a waterproof function is not particularly required. In addition, when the waterproof sheet 15 and the sheet-like members 18 and 22 are not formed of a photocurable resin, the waterproof sheet 15 and the sheet-like members 18 and 22 may be bonded with a known bonding material such as an adhesive.
[0037]
In this embodiment, the anchor member 16 is fixed to the concrete 10, and then the sheet-like member 18 is disposed above the anchor member 16 so as to cover it. However, the sheet-like member 18 may be arranged in advance at the position where the anchor member 16 is installed, and the anchor member 16 may be driven into the concrete 10 so as to penetrate the arranged sheet-like member 18.
[0038]
Further, in this embodiment, an anchor member having a disk-shaped flange portion 16c as shown in FIG. 2 is used as the anchor member 16, but the present invention is not limited to this, and the flange portion 16c is a circular shape. Other than the plate shape, it may be formed in other shapes. For example, the anchor member 16 may be formed in an L shape, a T shape, or the like, and may be formed in a simple bar shape without the flange portion 16c.
[0039]
Next, another embodiment of the fixing structure according to the present invention will be described. FIG. 5 shows another embodiment of the fixing structure according to the present invention. In this embodiment, as shown in the figure, the case where the protective concrete 40 is installed on the concrete 10 is shown. The existing waterproof layer 12 is interposed between the concrete 10 and the protective concrete 40. In such a case, the anchor member 16 is driven so as to penetrate the protective concrete 40 and reach the concrete 10. The new waterproof layer 14 is installed by laying a waterproof sheet 15 on the protective concrete 40 so as to cover the anchor member 16. The configuration above the waterproof sheet 15 is the same as the configuration shown in FIG.
[0040]
Thus, even when the protective concrete 40 is installed on the concrete 10, the fixing structure according to the present invention can be applied.
[0041]
In the above-described two embodiments, the renewal work of the waterproof layer in which the new waterproof layer 14 is provided on the existing waterproof layer 12 has been described as an example. However, the present invention is not limited to such a renewal work. In the case where a waterproof layer is not provided at all and is newly provided, for example, it may be applied to a new construction of a building.
[0042]
