Description

Solar System Frame System {FRAMING SYSTEM FOR SOLAR PANELS}

The present invention relates to a frame system, and more particularly to a system suitable for mounting panel members or plates to a support structure. The present invention describes the installation of a solar panel (also called a solar panel), also known as a PV (Phothvoltaic) panel, which is suitable for mounting at an angle that is appropriate to the sun and is horizontally inclined. It is not limited and can be applied to similar fields. In this description, the case of installing on the roof will be described as an example, but it goes without saying that it can also be used for vertical walls such as a PV exterior wall installation system.

In the field of solar PV panels, PV panels have the general characteristics of roof tiles so that PV laminates can be installed on, but not limited to, roof tiles. On the other hand, this panel can be made suitable for installation on a roof. However, an important consideration in the design and development of PV panels is that they can be effectively installed in the form of roofs architecturally. In addition to the PV electrical energy used inside the building where the PV tiles are installed, the panels installed on the roof have more opportunities to absorb solar energy, which is known as the solar energy development field known as PV / T (thermal). When installing these panels on a typical roof, the most important are the tiles, metal systems, convenient mounting elements inside the roof, and effective sealing elements.

One of the known ones is to have a structural feature that makes it easy to mount solar panels or tiles with a frame for mounting PV laminates to the roof supports by sealing them around the PV laminate. However, the frame is fixed in size and may not be suitable in some cases, for example, it may not fit the standard shoring spacing. If the size is fixed, the number of PV sheets that can be installed in the frame is also severely limited. If PV sheet size is specially ordered, the price rises and market competitiveness decreases.

Other existing roofing frame systems use extruded frame sections that require additional structures under the PV sheet to ensure weather resistance, or require more elements to connect to the roof, and in some cases are notable for external environmental conditions. In appearance, the aesthetics may be less apparent. These systems often require many inventory elements to be manufactured, stored, transported and installed, and are not necessarily PV installation systems applied to simple frames that inevitably enclose PV sheets. An ideal PV laminate frame system is simply installed in a building by simply being bonded to the PV laminate during the manufacturing process.

This makes it a new and useful system that can be easily assembled at the factory with its standard size, its size enough to be applied to the PV sheet of a standard manufacturing line, yet it can be easily installed on the roof with minimal additional cost, and can be effectively weathered. need.

The present invention provides a frame system for mounting a solar thin plate to form a solar panel to be installed obliquely in a building:

5 shows a joint between adjacent solar tiles. The side frame 14 is an aluminum extrusion, but may be a plastic extrusion. These extrudates have a channel 24 between the tubular body portion 23 and the walls, and sandwich the solar tile sheet 25 into the channel 24 to be hermetically sealed to the polymer channel seal 26. The top 28 edge 28 is secured over the tip 29 of the polymer seal and thus protected from the effects of rain, ultraviolet light, or the like, so that a reliable seal can be established and maintained. The upright sidewall 31 of the tubular body portion 23 has an undercut for inserting the T-shaped rib 32 of the elastically deformable tubular seal 33.

The tubular seals are designed to precisely adjust the gap between the upright confinement walls 35 of the tubular body part while the solar panels are slightly apart from each other. Each of the walls 35 protrudes upwards from the shoulder 36 which snaps into the protruding cover strip 37. The cover strip 37 may be conveniently screwed in place in the lower frame of the next tile in the system 63 shown in FIG. 2. Since the fixing screw penetrates the pedestal 11, the entire solar tile can be firmly fixed to the supporting structure so as not to be dropped by the wind.

The mushroom groove 38 in Fig. 5 is formed integrally with the side extrusion element so as to fit a snap or screw fastening element of a corresponding shape that secures the transverse support in place.

In FIG. 6, the upper frame 40 for the inner solar tile is shown together with the lower frame, and the lower frame is composed of two parts 41 and 41A (snap coupling parts) so as to overlap each other at an installation position. As shown in FIG. 3, joints are formed at each corner of the rectangular frame, and two screws 42 are fastened to the side wall 31 of the side frame to correspond to the corresponding storage spaces in the upper and lower frames 40, 41, and 41A. Screw on the wire 43).

The rear wall 45 of the upper frame 40 extends downwardly the restriction wall 46 coupled to the back of the brace 61, fixing the solar tile and the solar tile support side wall 47 in place. All condensate falling from the upper solar tile sheet 49 flows along the upper surface of the wall 50 and then passes through the groove 47A and the gap between the upper and lower elements 41d provided for weathering purposes. An upright protrusion 48 to be discharged to the outside is formed on the rear wall 45.

The wall element 50 also acts as a grazing channel formed between the pair of wall surfaces 52 and 53, and the U-shaped polymer sealing element 54 is disposed between the pair of wall surfaces 52 and 53. do. The lower frames 41 and 41A likewise have a U-shaped polymer element 55 which is hermetically bonded to the thin plate 49, and further under the groove 41C of the snap-in portion 41A is a "moist" polymer seal 55A. Is provided. The snap coupling portion 41A is engaged by the underframe snap coupling portion 41B to be engaged with the lower frame 41, and the wet sealing polymer material 55A is halved through the orifice in the groove 41C of the snap coupling portion 41A. After coating in a liquid state is fixed in place on the solar panel (49).

The front wall of the lower frame 41 has a bottom wall 47 fixed to the shallow groove 47A of the upper surface of the upper frame 40 and supported on the upper surface of the upper frame 40, and is curved while extending downward from the bottom wall. The protrusion 58 covers the sealing element 54 for weathering purposes. The lower element 41D of the lower frame 41 does not directly contact the upper surface of the upper frame 40 but leaves a gap for discharging moisture to the outside of the inner solar panel 49A.

Various details of the system described above with reference to the drawings have obvious advantages, and summarize the important features as follows.

1. In order to protect the polymer sealing elements from the weather, in particular the outer cover is placed in the channel so that it is not directly exposed to ultraviolet light. In the case of the upper frame, the sealing element is exposed, but then covered and protected by the lid projection of the lower frame of the tile.

2. The transverse supports can be easily mounted in the desired position by snap coupling or screwing, and can be installed in the proper position for the existing braces, especially when repairing existing roofs. The height of these transverse supports can also be selected according to the position of the frame.

3. A pair of grooves 46A are formed in the leg portion of the upper frame of the preferred form to reduce the contact area between the leg portion and the brace, thereby minimizing the possibility of moisture between the legs to improve durability. For the same purpose, the groove 47A and the downward protrusion 62 are formed in the upper frame of the preferred form.

4. As shown in Fig. 5, an elastically deformable tubular element 33 is provided to form a suitable spacing between adjacent units, which allows for a constant spacing while permitting movement by thermal expansion or thermal contraction.

5. The preferred embodiment uses plastic spacer elements as shown in FIG. 4, which can avoid air circulation and moisture gathering, thereby preventing the wooden roof props from rotting. In addition, when these plastic elements are assembled to an aluminum extrusion cross support, the desired angle of inclination can be set. The downward protrusion 62 of the upper frame 40 also induces a pitch angle with respect to the roof brace of the upper frame. Since the pitch height is formed to fix the lower frame 41 to the correct height with respect to the braces below it, the upper frame 40 can be used to take a gap between the brace and the lower frame 41 when the lower tile is in place. have. Thus, internally installed tile members corresponding to the roof tile system are obtained.
