Description

[Detailed description of the invention] The present invention relates to a mounting structure for fixing a plate-shaped body in a covering manner to an opening of a frame body such as a window frame.

The present invention will be explained below by taking as an example a structure in which a transparent plate is attached to a casing of a solar heat collecting plate.

In Fig. 1, sealing materials or gaskets 2' and 3' are arranged in a sandwich pattern above and below the outer edge of a transparent plate 1', and a transparent plate holding member with an L-shaped cross section is applied from above the upper gasket 3'. 4' and tightened to the side wall frame 7' of the casing 6' of the solar heat collecting plate using screws 5 etc. to protect the transparent plate 1' from rain. Since it is impossible to apply sufficient pressure in the vertical direction of ', there is a drawback in sealing performance.

In Fig. 2, the screw 5' is installed perpendicularly to the upper surface of the transparent plate holding member 4' in order to apply sufficient pressure to the gaskets 2' and 3'.
Rainwater easily enters through the screw holes, and there is a risk that the entered rainwater may flow along the upper surface of the side wall frame 7' and enter the inside of the heat collecting plate.

In FIG. 3, a light-transmitting plate support portion 8' is erected to protrude upward from the upper surface of the side wall frame 7' so that the rainwater that has entered does not enter the inside of the heat collecting plate. A screw attachment portion 9' is provided upright outside the transparent plate support portion 8' on the upper surface. Rainwater that has entered through the screw hole of the screw 5' is prevented from entering the inside of the heat collecting plate by the tall transparent plate support part 8', and the water drain hole 10' provided at the base of the screw mounting part 9' The liquid flows through a channel 11' formed between the transparent plate holding member 4' and the screw attachment part 9', and is appropriately discharged to the outside. Although the conventional example shown in FIG. 3 appears to have a nearly complete structure, a large number of screws are used to attach the light-transmitting plate holding member, similar to the conventional examples shown in FIGS. 1 and 2. On the other hand, heat collecting plates are usually installed on a sloped surface facing south, such as a roof. Therefore, when a strong north wind blows against this, negative pressure acts on the transparent plate on the leeward slope, and a force that lifts the transparent plate acts.
In order to counteract the above problems, the screw diameter and thread length had to be increased, which tended to make the screw seats thicker, which in turn led to an increase in the weight of the casing. Heat collecting plates are originally installed on roofs with low strength, and an increase in weight is extremely undesirable from the viewpoint of handling.

The present invention was made in view of the drawbacks of the conventional structure.According to the present invention, a mounting structure is provided in which a plate-like body is fixed to an opening of a casing in a covering manner, and the end surface of a frame constituting the opening A plate-shaped body support part that supports the inner surface of the plate-shaped body is formed on the inner edge, and a first plate-shaped body support part that engages with a plate-shaped body holding member to press the outer surface of the plate-shaped body is formed near the end surface of the frame body. an engaging portion is formed, and a second engaging portion that engages with the first engaging portion is formed on the plate-shaped body holding member, and the frame body or the second engaging portion near the first engaging portion is formed. A wedge body is integrally formed on the plate-shaped body holding member nearby, and after the plate-shaped body is placed on the plate-shaped body support part, a second wedge body is formed.
The present invention provides a mounting structure for a plate-shaped body in which a wedge material is press-fitted between a plate-shaped body holding member and a casing frame when an engaging part is engaged with a first engaging part.

Hereinafter, the present invention will be described with reference to embodiments with reference to the accompanying drawings.

As shown in FIGS. 4 to 6, header pipes 2, 2 are connected to the ends of the heat collecting pipes 1 arranged at predetermined intervals, and heat collecting fins 3 are connected between the heat collecting pipes 1.
are attached in an assembled manner to form a heat collecting plate, which is housed in the casing 4. Reference numeral 5 denotes a feeder tube attached to the end of the header pipe 2 and protruding outward from the casing 4.
It is a drain cap. The heat collecting tube 1 is made of a metal material with good thermal conductivity such as copper, and is made of a metal material with good thermal conductivity such as copper, and the heat collecting fin 3 is made of an extruded material such as an aluminum alloy, and the surface facing the sun is painted black. Or perform endothermic treatment such as selective absorption membrane.

The casing 4 has a box shape with an upper opening and is composed of a side wall frame 6 and a bottom plate 7, and the side wall frame 6 and the bottom plate 7 are joined with pop rivets 8 or the like. A transparent plate support part 9 having a C-shaped groove or the like on the upper part is erected on the inner edge of the upper surface of the side wall frame 6 of the casing 4, and a gasket 10 is fitted into the C-shaped groove 9A of the support part 9, and the gasket 10 is placed on top of the gasket 10. The lower edge of the transparent plate 11 is placed on.

Further, near the outer edge of the upper surface of the side wall frame 6, a protrusion 12 having a substantially square cross section is provided upright. The protrusion 12 has an arcuate recess 13 at its upper end constituting an engaging portion facing downward.
has.

On the other hand, the transparent plate holding member 14 has a vertically parallel long side 14A and a short side 14B, and is formed in a square cross section.
The wedge body 1 is provided with a circular arc portion 15 constituting an engaging portion that fits into the circular arc recess 13 of the wedge body 1 through a thin connecting portion 17A near the lower outer edge of the short side portion 14B.
Form 7B. It is preferable that the arcuate portion 15 is formed to have a circular cross section so that it can rotate smoothly within the arcuate recess 13.

For installation, fit the arc portion 15 of the light-transmitting plate holding member 14 into the arc-shaped recess 13 of the protrusion 12, and first fit the long side 14A of the light-transmitting plate holding member 14 into the light-transmitting plate support portion. 9
Another gasket 16 is inserted between it and the transparent plate 11 placed above. In this state, both gaskets 10
The force that clamps the transparent plate 11 is not yet acting on and 16. Next, bend the above connection part 17A and attach the wedge body 17B to the short side part 14 of the transparent plate holding member 14.
B and the outer edge of the upper surface of the side wall frame 6 of the casing 4. When the wedge body 17B is press-fitted, the light-transmitting plate holding member rotates by the lever principle using the contact line between the arc-shaped recess 13 and the circular arc portion 15 as a rotation fulcrum, and the light-transmitting plate holding member rotates. Press the gasket strongly with the inner edge of the lower surface of the long side 14A of the gasket 14 to remove both gaskets 10.
and 16, the transparent plate 11 is closely held between them.

Although the above embodiment describes the casing of a solar heat collecting plate, the present invention is not limited to this, and can be applied to any open frame, such as when fixing a plate to the opening of a window frame. It can be used to fix a plate-like body covering the body, and such a frame can be arranged not only horizontally as shown in the figure but also vertically or inclinedly. Also, the connecting portion 17A and the wedge body 17
Although B is provided on the holding member side, it is also possible to provide it on the frame side, and there is no problem even if the connection portion is separated when the wedge body 17B is press-fitted.

Figures 7 to 10 are views showing another embodiment of the present invention, and Figure 7 shows a light-transmitting plate holding member 14 and a side wall frame in order to prevent the press-fitted wedge body 17B from falling out during use. Engagement recesses 18 and 1 in body 6
FIG. 8 is different from FIG. 7 in the orientation of the arcuate recess 13 and the arcuate portion 15. In addition, the embodiment shown in FIGS. 9 and 10 has a connecting portion 17.
A and a wedge body 17B are formed on the side wall frame 6 side, and in FIG. It is formed by bending. Further, FIG. 10 shows that the protrusion 12 is made to protrude outward by forming a descending stepped portion from near the center of the upper surface of the side wall frame 6 toward the outer edge, and an arcuate recess 13 is formed at the tip of the protrusion 12. There is.

The present invention is constructed as described above, and wedges are used instead of screws as in the conventional structure, so that it has sufficient strength even if the holding material and side wall frame are made thinner and lighter in structure. It is also extremely easy to assemble and disassemble.

The advantages of forming the wedge material integrally with the presser material are as follows.

・Wedge materials can be prepared from the beginning.

・Since the length of the wedge material is the same as the length of the holding material or frame body, there is no need to cut the wedge material to size on site.

- Never forget wedge materials during construction.
