Description

[Detailed Description of the Invention] The present invention relates to a waterproof structure for a roof constructed of solar heat collectors.

Solar heat collectors are usually installed on the slope of the roof facing the sun during daylight hours.

To install this type of heat collector, it is necessary to install the heat collector in parallel with support members in the flow direction of the roof, support the heat collector between the parallel support members, and wrap the heat collector around the four peripheries of the heat collector. = Tighten the four circumferences of the gasket to the supporting material using a presser cover.

However, it is difficult to completely seal off the gaps between the packing and the presser cover and between the packing and the heat collector from rainwater.

Furthermore, since the heat collector is located high above the building, it vibrates due to the wind pressure during strong winds accompanied by rain and rain, causing rainwater to leak from the above-mentioned gaps.

However, the amount of water leaked in this case is relatively small.

On the other hand, the heat collector itself may fail and a heat medium such as water circulated by a pump or the like may leak into the heat collector.

・Leakage of heat medium due to failure of the heat collector occurs suddenly, and because it is sent by a pump, it occurs continuously, and the amount of leakage is much larger than that of rainwater = Also, the location of the leakage is This occurs more often on the indoor side of the heat collector than on the outdoor gasket of the heat collector.

Moreover, if such indoor water leakage occurs, it cannot be inspected from the outside like a rainwater prevention gasket.

As mentioned above, especially if the heating medium leaks, there is a risk that the damage will be greater because the detection will be delayed.

The present invention has been made in view of the above, and includes forming a heat collector support part on a support member that supports the heat collector, and extending a cross-sectional channel protrusion on the side wall of the support member below the part support part. The waterproof board supporting part and the bridge part are formed integrally with the supporting material, and the waterproof board is installed across the waterproof board supporting part, and the height of the waterproof board supporting part is set to be equal to the bottom of the heat collector and the waterproof part. By creating a gap between the plates, the fear of causing great damage due to leakage of the heat medium or leakage of rainwater is eliminated.

The present invention will be described below with reference to two embodiments.

[First embodiment] A solar heat collector is installed on the roof of a building, for example, a support member 1 and a short horizontal member 2 are provided on the roof surface in the direction of roof flow, and a short horizontal member 2 is provided directly between the support members. A solar heat collector 3 is installed in the space between the two materials.

Since the supporting material 1 is also used as a drainage ditch, a long shaped material is usually used (Fig. 1).

As shown in Figure 2, the heat collector 3! Translucent plate 4 such as glass,
It is convenient to include a heat collecting plate 5 made of a metal material, and to hermetically bond the four peripheral edges of the light transmitting plate and the heat collecting plate with a spacer material 6 and a sealing material 6a.

The support member 1 is made of a U-shaped member with an upward opening, and is provided with heat collector support parts A, A on both outer and upper sides, and the side edges of the heat collector 3 are supported on the support parts via packings 7.

Furthermore, the heat collector 3 is fixed to the support material 1 by tightening the heat collector press cover 9 to the support material 1 via the pressure gasket 8 provided on the edge of the heat collector 3.

, 10 is a joint pipe communicating with the heat collecting pipe 5a of the heat collecting plate; 1. The heat medium flows through the elbow 11.1 to the joint hose, and through another elbow 1:1.a and the joint pipe 10a to the heat collector 3 adjacent in the flow direction of the roof.

The above-mentioned joint hose 12 and elbow IL 11a are the support material 1
The upper opening is covered with a cover plate 13.

14 is a heat insulating material provided behind the heat collector 3, and 1:5 is an anti-icing sheet placed on the roof board 16 over the entire roof surface.

. At the lower part of the support member 1, a channel protrusion 17 having an L-shaped cross section and projecting laterally is formed integrally with the support member 1.

This L-shaped channel protrusion piece 17 has a hammer part 18 at the base of the support member 1, and a waterproof plate support part 19 near the free end of the protrusion piece 17. For example, the distance between the waterproof plate supports 19 between the materials 1 is about 0.5? l! I1
A waterproof plate 20 made of an aluminum plate with a thickness of 1 mm is attached.

Also, the height of the waterproof plate support part 19 is compared to the heat collector support part A so that a gap is formed between the bottom surface of the heat collector 3 supported on the heat collector support part A and the waterproof plate 20. , and is set to a low position.

・ ...Patzkin club as mentioned above! Water leaking from the heat collector 3 falls onto the waterproof plate 20 located below them, and then flows through the mallet part 18 and is drained.

Furthermore, it is convenient to provide a small extension 21 extending toward the inside of the hammer part 18 at the edge of the waterproof plate 20, since the small extension serves as a drain.

As shown in FIG. 3, the cross member 2 is made of a U-shaped cross section, and has heat collector fitting grooves B, B on both outside sides thereof, and the heat collector 3
The end edge portion of the support gasket 22 is supported through the support gasket 22.

In addition, 23 is a presser gasket for the weft material, and 24 is a weft material presser cover plate.

In the figure, the horizontal material is attached to the waterproof plate support part 19 using screws.
is fixed to.

[Second Embodiment] FIG. 4 is a plan view of the waterproof structure and the second embodiment, with some vertical covers 13A and lateral covers 24A removed.

Reference numeral 25 denotes a supporting member, a connecting fitting between 1 and the vertical cover 13A, and 26 a connecting fitting between the supporting member 1 and the heat collector 3, such as the collector support portion A.

As shown in FIG. 5, an end fire material 28 is attached on top of the main building 27, and the main building 27 and the support member 1 are connected via the end fire material 28 with an L-shaped metal fitting 29.

・ □ In Figures 6 and 7, the support member 1 has a box-shaped cross section, and is shown inside the box body 3' by the connecting fitting 26 attached to the heat collector support part A formed on the upper part. The ends of the heat collector 3, including the heat collector plates that do not have heat collectors, are supported.

An L-shaped channel protrusion 17 is laterally protruded from the middle of the side of the support member 1.

Waterproof plate support portion 19 of adjacent L-shaped channel projection piece 17
while! The edges of the waterproof plate 20 are then attached with screws 30, and the vicinity of the screw heads are sealed with an amorphous sealing material to prevent water from leaking from the screw attachment holes.

As described in the first embodiment, since the waterproof plate 20 is a thin aluminum plate, in order to prevent it from bending, the fireproof plate 32 is placed between the portions 31 of the receivers extending from the L-shaped channel projecting piece 17. Back up the waterproof board 20.

The bridge part 31 has a small bridge part 33 in order to make the waterproofing even more complete.
is in great shape.

A connecting fitting 25 is connected between the vertical cover 13A and the support member 1.
When installing the I cover, cover the upper part of the bolt 34 with tight material 3 and 5 (Fig. 7).

As shown in FIG. 8, the space between the lateral cover 2.4^ and the transparent plate 4 of the heat collector is sealed in the form of a slope at a portion 36 to improve drainage.

A two-way cover 24 is installed to prevent rainwater from leaking in this area.
The lower part of A is extended downward to form a horizontal gutter 37, and is dropped onto the waterproof board 20 from the end of the horizontal gutter 31.

Since the present invention is constructed as described above, even if there is a leakage of heat medium etc. from the heat collector itself as well as rainwater intrusion from the vertical joints and horizontal joints, these leakages can be prevented from entering the support material. Since water is discharged towards the lower end of the roof along the surface of vertical gutters or waterproof boards formed in the roof, it does not enter the interior of the house.

Furthermore, since a gap is provided between the bottom of the heat collector and the waterproof plate, condensed water and the like will not accumulate in the space, and there is no risk of corrosion of the heat collector.

In addition, since the bottom of the heat collector does not touch the waterproof plate, strong winds and
Even if the heat collector vibrates due to an earthquake, etc., the waterproof board will not be damaged.

Furthermore, since the waterproof plates are simply supported and fixed between the support members 19 and 19, there is no connection between horizontally adjacent waterproof plates, making it easy to install the waterproof plates.
