Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a capping board that is attached to the rising top surface of a parapet of a building to waterproof and protect the surface, and the present invention relates to a capping board that is attached to the rising top surface of a parapet of a building to waterproof and protect the surface. It is designed to circulate heat and exchange heat.

(Conventional technology and its problems) Conventional caps that cover the top surface of parapets, etc.
As illustrated in FIG. 9, the parapet top end 21
A substantially downward U-shaped holder 23 is fixed with an anchor bolt or the like at appropriate intervals, and a substantially downward U-shaped drain plate 24 is provided at the joint position of the cap 22, and the parapet ceiling is attached from above. A long cap 22 having lower folded surfaces on both sides of the upper surface covering the end face was fitted so that the lower ends of the lower folded surfaces elastically engaged with the lower ends on both sides of the holder. . Although such caps cover the top of the parapet and are effective in waterproofing and protecting it, most of them are on rooftops or outdoors and are heated or cooled considerably by sunlight, so they are subject to large thermal expansion and contraction. It is something that is repeated.

The present invention focuses on the fact that the cap is placed in a position that receives the most sunlight as described above, and aims to provide a cap that is capable of heat exchange and can alleviate the thermal expansion and contraction of the cap as much as possible. It is something.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a cap that covers the top end surface of a parapet, etc., and has a hollow section in its cross section that communicates with the longitudinal direction so that heat can be exchanged. It is characterized by the composition of Kasagi.

(Example) Next, the present invention will be explained with reference to drawings shown as an example.

FIG. 1 shows a cross-sectional view in the width direction of the Kasagi according to the present invention, and the Kasagi 1A has lower folding plates 3, 3 formed on both sides of the upper surface 2 that covers the top end surface of the parapet to cover the upper portions of both sides of the parapet. At the same time, the upper surface 2
A hollow passage 4 penetrating in the longitudinal direction is formed within the wall thickness. In the figure, four hollow passages 4 are formed through the partition walls 5, but the shape and number of the passages may be set arbitrarily. 6 is a water stop ridge formed along one side edge of the upper surface 2 to prevent rainwater from flowing down to the outside of the parapet, and 7 is a lower folding plate for engaging the cap 1A with the holder 8. This is a locking part that protrudes inward from the lower end of 3. The holder 8 does not need to be different from conventionally known holders, and has a substantially downward U-shape with an appropriate downward opening, and is attached to the top end surface of the parapet so that the cap 1A is fitted and supported with a water slope toward the inside of the parapet. Fixed.

The required number of the above-mentioned capacitors 1A is arranged according to the length of the parapet, and between each capacitor 1A, a hollow flexible joint 9 is glued and integrated on the end face of the capasagi, as shown in FIG. (Although not shown in the figure), a flexible joint may be fitted or glued onto the end of the Kasagi, and water pipes may be connected to the end of the Kasagi as appropriate, as shown in Figure 3. A hollow flexible joint 10 for communicating with a water supply source such as a heating tank, a water supply destination such as a faucet, etc.
are connected in the same way as above. As shown in Figure 4, the joint part of each cap has a width that spans the inside of the ends of both caps and is parallel to the joint so that the ends of the caps will not come off even if the caps expand and contract. A drain plate 11 is provided which has an uneven shape in the direction of the drain plate.

The above-configured Kasagi can be used as a so-called solar heat exchange system that can generate fairly high-temperature hot water by circulating water through the hollow passage 4 and absorbing the solar heat received by the Kasagi. The hot water can be used, for example, for daily use in baths and showers, various hot water supplies, for heat sources in offices and factories, and for other heat sources, and the heat exchange can suppress the thermal expansion of the Kasagi. It also has the effect of being able to do the same thing. In addition, hollow passage 4
By distributing cooling water that absorbs heat through equipment in offices and factories, and discharging heat during the Kasagi distribution, in addition to heat exchange with hot water, cooling shrinkage of the Kasagi can be suppressed, and cooling water can be distributed to the Kasagi during snowfall. It is possible to create a system that has effects such as preventing the accumulation of snow.

Each of the hollow passages 4 shown in Fig. 1 may be configured such that water from the same water supply source is divided into all passages and allowed to flow in the same direction, or some passages and other passages are arranged in a forward and return way. Alternatively, some passages may be connected to other water supply sources or water supply destinations.

Note that it is also possible to pass liquid other than water or gas through the hollow passage 4.

5 to 8 show examples of modifications to the example in FIG. 1, and FIG. 5 is an example of a Kasagi 1B in which the hollow passage 4B is formed as one passage without a partition wall,
FIG. 6 shows an example of a Kasagi 1C in which each hollow passage 4C is formed individually protruding from the lower side of the upper surface in order to make the entire Kasagi of FIG. 1 approximately the same thickness.
A Kasagi 1D is formed by arranging longitudinal engagement protrusions 12 in parallel on the lower side of the upper surface of the Kasagi, and fitting a pipe 14 having a separately molded hollow passage 4D between the engagement protrusions 12 and 12. Figure 8 shows the inside part of both edges from the top surface of the Kasagi to both lower folded plates, which has a gap between it and the holder to be fitted, in order to prevent the thickness from increasing due to the hollow passage on the top surface. hollow passage 4
This is an example of Kasagi 1E who formed E. Modifications other than these are also possible.

The upper surface may be uneven as long as it does not impair drainage of rainwater, and may be uneven as long as it takes into account drainage, such as a step-by-step configuration in the drainage direction.

(Effects of the Invention) As described above, the present invention provides a heat exchangeable cap that can be easily molded by extrusion processing, etc., does not make hollow passages noticeable, and has almost no difference in appearance from conventional caps. It is possible to waterproof and protect the top end of the parapet, and at the same time, it is possible to perform heat exchange of liquid or gas flowing through the hollow passage by sunlight or outside air. This heat exchange has an extremely large labor-saving effect.
