Description

[Detailed Description of the Invention] The present invention relates to a frame fixing structure for a solar heat collector in a solar water heating system.

The purpose is to be able to easily place and fix the heat collector on the frame, to have high strength, and to have a good appearance.

The present invention will be explained below based on the embodiment shown in the drawings. A plurality of cat bolts 1 whose bases are fixed to a moya wood 6 and whose upper end threaded parts 2 protrude above the roof are connected to the threaded parts 2 of several bolts. Frame 10a, 10b, 1
0c and 10d were fixed at appropriate intervals, and an irregularly shaped hole 13 was formed at a suitable location on this stand frame, with a large diameter hole 13a in the upper part communicating with a long hole 13b having a width smaller than the diameter of the large diameter hole in the lower part. Multiple mounting plates 12...
This is a heat collector frame fixing structure in which a frame is constructed by providing a frame, and protrusions 14 protruding downward from the heat collectors 11a, 11b, 11c are fitted into the anisotropic holes 13 of the mounting plate and fixed. .

The cat bolt 1 has a bolt rod 3 having a male threaded portion 2 carved in its upper end and fixed to the back surface of an L-shaped plate 4. Reference numeral 5 designates nail holes formed in the back plate and bottom plate of the L-shaped plate 4. Such a cat bolt 1 has its base L-shaped plate 4 made of moya wood 6.
Place the nail in the specified position and secure it through the nail hole. After fixing a plurality of cat bolts 1 to the moya wood 6, the roofing board 7, roofing 8, and roofing material 9 are covered on the moya wood 6. In this way, the male threaded portion 2 carved into the upper end of the bolt rod 3 protrudes above the roof. The contact portions between the bolt rod 3 and the roofing 8 and roofing material 9 are waterproofed with caulking material or the like.

10a, 10b, 10c, and 10d are stand frames. This table frame 10a is fixed by the male screw portion 2 of the above-mentioned cat bolt. That is, the male screw portion 2 is inserted into the through hole 15 formed in each frame and fixed by tightening a nut. The stand frame 10a shown in the drawing...
... is an L-shaped steel in cross section, but the shape is not limited to this. Furthermore, although four stand frames are used in the drawings, this number is determined by the number and size of the heat collectors to be mounted.

There are cases where the roof is fixed along the slope of the roof as shown in the drawings, and cases where it is fixed perpendicular to the slope. Base frame 10a... Heat collector 11 on top
A, 11b, 11c are mounted and fixed, and as means for fixing this heat collector, a plurality of mounting plates 12 are provided at appropriate positions on the base frame. This mounting plate 12 is formed with several irregularly shaped holes 13 in which a large diameter hole 13a is formed in the upper part and a long hole 13b having a width smaller than the diameter of the large diameter hole is communicated in the lower part.

As shown in FIG. 4, the mounting plate 12 is installed on the stand frame via leg frames 16. The irregularly shaped hole 13 is formed by, for example, the base frame 10a at both ends,
Two mounting plates 12 are formed in one row in the vertical direction on the mounting plates 12 provided at 10d, and two mounting plates 12 are formed in two rows in the vertical direction on the mounting plates 12 provided on the middle platform frames 10b and 10c. In this way, the frame is constructed by combining the cat bolt, stand frame, and mounting plate.

In the figure, reference numerals 17 are receiver pieces provided at the upper and lower ends of the stand frame 10a, and are used to attach frame plates that decorate the periphery of the stand. The stile plate consists of upper and lower stile plates 18a, 18b, and left and right stile plates 19a, 19b. 20... is a mounting piece provided on the inner surface of each frame plate, and this mounting piece 20
... is placed on the receiving piece 17 and fixed with screws.

11a, 11b, 11c are heat collectors, and side edges 21a, 21b, 21c provided around the heat collectors.
A protrusion 14 that fits into the anisotropic hole 13 described above is protrudingly provided at a proper position on the lower surface of the . This protruding portion 14 is provided at a position corresponding to the above-described irregularly shaped hole 13, and in the drawing, it is provided by passing a bolt through the side edges 21a, 21b, and 21c from the upper surface to the lower surface. That is, the protrusion 14 shown in the drawing is the lower end of the bolt. In addition to this embodiment, side edges 21a, 21
The protrusions 14 may be formed by welding or the like to provide protrusions at appropriate locations on the lower surfaces of b and 21c. 22 in the drawing is a washer.

The heat collectors 11a, 11b, and 11c are fixed by inserting their protrusions 14 into the anisotropic shapes 13 of the mounting plate 12, as shown in FIG. During this fitting and fixing, the protrusion 14 can be first inserted into the large diameter hole 3a and then fitted into the elongated hole 3b, which has the advantage of making the fixing work easier. Although the protrusion 14 is just the lower end of the bolt as shown in the figure, it will not come off due to the weight of the heat collector, but just in case
It is preferable to attach a nut (not shown) or the like to the tip of the protrusion 14 to prevent the protrusion 14 from coming off the irregularly shaped hole 13.

The frame structure of the heat collector of the present invention is an excellent idea that achieves the following effects.

(a) The base frame that fixes the heat collector is firmly installed on the roof with cat bolts, so the fixation of the heat collector on the roof is reliable and strong.

(b) A mounting plate is used to fix the heat collector to the base frame, and the protrusion provided at the bottom of the heat collector is inserted into the irregularly shaped hole formed in this mounting plate and fixed to the base of the heat collector. Easy to install and fix. In other words, even if there is some error, it can be corrected using the large diameter hole of the irregularly shaped hole, so even non-experts can easily work on it.

(c) A good-looking finish can be achieved because there is no need to pull the heat collector with wire, etc., or expose bolts on the outside surface.
