Description

[Detailed description of the invention] [Industrial field of application] This invention relates to the structure of a parapet cap that is attached to the corner of the top and outer wall of a building, such as a parapet or a ground cover below a balustrade.

[Prior art]

Figure 2 shows the top of a conventional parapet. A waterproof sheet 2 is laid covering the inner wall and top of the parapet 1, and a Kasagi bracket 3 with a U-shaped cross section is placed on top of the waterproof sheet 2. is mounted and fixed with anchor plugs 4, 4, and a parapet cap 5 is provided covering the top surface thereof. When installing this parapet cap, the Kasagi bracket must first be attached using an anchor plug, which is a time-consuming process.
In addition, there were problems in that the parapet Kasagi terminal processing was difficult and required skilled skills.

Figure 3 also shows a conventional parapet. At the top end of the parapet 1, a laminated steel plate 8, which is made by laminating soft vinyl chloride resin 7, 7 on both surfaces of a steel plate 6 as shown in FIG. A waterproof sheet 2 is adhesively fixed to a laminated steel plate 8 and laid over the upper surface of the parapet cap, which also serves as a waterproof layer. This parapet cap is covered with a waterproof sheet that is continuous with the inner wall of the parapet, so there is no problem in terms of waterproofing, but dust etc. adhering to the top end are washed away by rainwater to the outer wall surface, contaminating the outer wall surface. In order to prevent this contamination, the outer wall side of the laminated steel plate 8 is made to extend outward.
The edge of the waterproof sheet 2 overlaid on the surface is rolled up to the back side of the edge of the laminated steel plate 8 and fixed, and the back-up material 9 and sealing material 10 are further pushed deeply between the laminated steel plate 8 and the outer wall surface to close it. be. With this structure, when the dirt on the top surface of the cap is washed away by rainwater, it falls along the lower end of the overhanging cap and does not adhere to the outer wall surface, thereby preventing contamination. However, it takes a lot of effort to extend the laminated steel plates from the outer wall, wrap a waterproof sheet around the back of the tip, and then push back-up material and sealant deeply to close the gap, resulting in low work efficiency and Ta.

[Purpose of invention]

This idea was made by paying attention to the above-mentioned problems. The purpose was to propose a structure for parapet caps that would not impair the waterproofness of the top edges of buildings such as parapets, and would also prevent dirt such as dust from flowing out from the top along with rainwater and contaminating the outer walls. There is something to do.

[Structure and implementation examples of the invention]

This parapet cap structure is an old parapet cap structure in which the cap is attached to the corner of the top of the building and the outer wall, and soft vinyl chloride resin is laminated on the surface of the steel plate at the top of the parapet. A waterproof sheet made of soft vinyl chloride resin that continues from the inner wall of the parapet is adhesively fixed on the top surface of the laminated steel plate, and the cap is made of synthetic resin and has an L-shaped cross section. It is characterized in that it has a water-stopping protrusion parallel to the L-shaped ridgeline and is adhesively fixed to the waterproof sheet.

This will be explained using the embodiments illustrated above.

In FIG. 1, a laminated steel plate 8 is installed at the top end of the parapet 1 over the inner and outer walls of the parapet 1.
It is fixed and arranged. The laminated steel plate 8 on the outer wall side (left side in the drawing) extends outward, and the gap between it and the outer wall surface is filled with backup material 9 and sealing material 10 to close it. On the upper surface of this laminated steel plate 8, a waterproof sheet 2 made of a soft vinyl chloride resin, which is continuous with the inner wall surface of the parapet 1, is adhesively fixed to the lower laminated steel plate 8. A parapet cap 11 having an L-shaped cross section is provided at the corner between the top end of the parapet 1 waterproofed in this way and the outer wall. This Kasagi 11
There is a water stop protrusion 1 on the surface of the top side parallel to the top edge.
2 is protruding. The cap 11 is made of a soft vinyl chloride resin, and is adhesively fixed to the waterproof sheet 2 made of the same kind of soft vinyl chloride resin.

[Effect]

The structure of this parapet cap has the above-mentioned structure. A laminated steel plate with soft vinyl chloride resin laminated on the surface of the steel plate is fixed to the lower layer of the cap, and a layer of soft vinyl chloride resin that is continuous from the inner wall of the parapet is fixed on the lower layer of the cap. Since the waterproof layer is formed by adhesively fixing the waterproof sheet, the waterproof layer has high strength and water-stopping properties. The cap has an L-shaped cross section and is adhesively fixed to the underlying waterproof sheet, allowing for strong installation without compromising waterproof performance. In addition, when the Kasagi is attached to the top corner, water-stopping ridges are provided that protrude parallel to the outer edge of the top side surface, that is, the ridgeline, so dirt on the top will not flow out onto the outside wall along with rainwater. There is no risk of contamination. Therefore, as shown in FIG. 3, there is no need to wrap the waterproof layer inside the edge of the laminated steel plate or to press the sealant deeply, improving workability.

Although the parapet cap 11 is made of soft vinyl chloride resin in the embodiment, it is not limited thereto. Other synthetic resins, such as vinyl chloride, polystyrene, polyacrylic, polyalkyd, polyethylene, or synthetic rubber (polybutadiene, polybutadiene/styrene/butadiene/acrylonitrile, polychloroprene, polyisoprene, It is also possible to use materials such as isobutylene-based, polyacrylic-based, polyurethane-based, fluoro rubber-based, silicone rubber-based, etc. Among these, those made of soft vinyl chloride resin are preferable because they can be easily and reliably fixed to a waterproof sheet made of soft vinyl chloride resin by solvent adhesion, heat-melt adhesion, or adhesive. In addition, when extrusion molding this parapet cap, a two-color extrusion method is used, and as shown in Fig. 5, the upper side 13 that can be attached to the top end is made gray, for example, which is resistant to sunlight, and the side edges 14 that can be attached to the outer wall side are made gray. For example, if you color it in Chiyocolate color from the design point of view, you can further enhance the functionality and design of this Parapet Kasagi.

[Effect of idea]

The structure of this parapet cap is as described above, and the combination of the cap and the underlying waterproof layer provides high water-stopping properties and strength. In addition, since rainwater does not flow from the top of the Kasagi to the outer wall, there is no need for complicated construction, making it easy to construct.
