Referring to Figures 1 to 8, the frame 100 of the solar module according to an embodiment of the present invention includes a solar module holding member 110 and a reinforcing member 120 for mounting the solar module 10. , supplementary fixing member 130, reinforcing wire 140, and tensile stress adjustment member 150.

The solar module holding member 110 is a lower support in the shape of a square pillar on which the solar module 10 is seated at the top, surrounds the four sides of the edge of the solar module 10, extends downward, and has the end bent inward. (111) is formed.

The reinforcing member 120 supports the rear of the solar module 10 to prevent the solar module 10 from sagging. For this purpose, the reinforcing member 120 can be implemented with a steel material, including a reinforcing upper plate 121 in contact with the rear of the solar module 10, a reinforcing lower plate 122 parallel to the reinforcing upper plate 121, and a reinforcing upper plate ( It is implemented in an H-beam shape including a central rib 123 connecting the lower support plate 122 and the lower support plate 122, and is fixed to the rear of the solar module 10 by spanning the refractive surface 111a of the lower support 111. That is, the reinforcing member 120 includes a refractive surface 111a of the lower support 111 extending downward from one side, and a refractive surface 111a of the lower support 111 extending downward from the other side facing that one side. Both ends can be draped over and secured to (111a).

The supplementary fixing members 130 are respectively coupled to both ends of the reinforcing member 120, and are formed in pairs to secure the reinforcing member 120 to the lower support 111. At this time, the supplementary fixing member 130 may supplement the length and height of the reinforcing member 120. That is, the supplementary fixing member 130 is reinforced when the length of the reinforcing member 120 is shorter than the distance between the refractive surfaces 111a of each of the plurality of opposing lower supports 111 and does not span the refractive surface 111a. The length of the member 120 is supplemented to be longer, and the height of the reinforcing member 120 is lower than the length of the lower support 111 extending downward, so the upper plate of the reinforcing member 120 (i.e. If the reinforcing top plate (121) does not support the rear of the solar module (10), the reinforcing member (120) is pushed upward to compensate for its height. Due to this, the supplementary fixing member 130 is firmly fixed to the lower support 111 so that the reinforcing member 120 is in close contact with the rear of the solar module 10 to prevent sagging of the solar module 10. make it possible

For this purpose, the supplementary fixing member 130 is inserted into both ends of the reinforcing member 120 to support the reinforcing member 120, and the body portion 131 protrudes from the body portion 131 in an 'ㄱ' shape to provide reinforcement. It includes a supplementary part 132 that complements the length and height of the member 120 and is mounted on the refractive surface 111a of the lower support 111, and the supplementary part 132 is connected to the reinforcement member 120 from the body 131. A length supplementary part (132a) that extends a predetermined length in the longitudinal direction to complement the length of the reinforcing member 120, and a height supplementary part (132a) that extends vertically from the length supplementary part (132a) and supplements the height of the reinforcing member 120 ( 132b), and is fastened through the fastening hole 133 formed on the bottom surface of the body portion 131 and presses the lower portion of the reinforcing member 120 (i.e., the lower portion of the reinforcing lower plate 122) to secure the body portion 131. It may include a plurality of pressurizing bolts 160 that combine the reinforcing member 120.

At this time, the supplementary length of the reinforcing member 120 is determined by the distance at which the reinforcing member 120 is inserted into the body 131, and the lower part of the reinforcing member 120 inserted into the body 131 and the body portion. The supplementary height of the reinforcing member 120 is determined by the distance between the bottom surfaces of (131). To this end, the pressure bolt 160 is fixed to the body portion 133 at a position corresponding to the supplementary length. It can be fastened, and in order to supplement the height of the reinforcing member, the lower part of the reinforcing member is pressed while maintaining a distance equal to the height that needs to be supplemented from the bottom surface of the body portion.

The height supplementary part (132b) responds to the pressure of the pressurizing bolt (160) by exerting force in the direction of the refractive surface (111a) to maintain the above-mentioned spacing, thereby pushing the reinforcing member (120) upward to supplement its height. Let it happen.

The supplementary fixing member 130 can be created by bending a plate-shaped member such as a metal steel plate in multiple stages, and a development diagram for this is illustrated in FIG. 3.

It may be composed of a metal plate. The size of each of the above areas is as shown in FIG. 3. At this time, the upper areas (C, C') are the width of the central rib 123 ( ) and must be formed horizontally with the floor surface (A), so the width of the upper area (C, C') ( ) can be calculated by Equation 1.

At this time, the reinforcing upper plate 121 is not inserted into the body portion 131, and only the reinforcing lower plate 122 is inserted into the interior of the body portion 131, and is inserted into the center along the rib path formed on the upper portion of the body portion 131. A rib 123 penetrates. This is to secure space so that the reinforcing lower plate 122 can compensate for the height of the space formed in the body portion 131 by moving upward by the pressure of the pressing bolt 160.

Meanwhile, in order to limit the movement of the supplementary fixing member 130, a slit groove 124 into which the lower surface 132-1 of the supplementary part 132 is inserted is formed between the central rib 123 and the reinforced lower plate 122. This is to prevent the supplementary fixing member 130 from moving excessively toward the center of the reinforcing member 120. For this purpose, the depth of the slit groove 124 ( ) is the width of the lower surface 132-1 of the supplementary part 132 ( ) is preferably formed in the same way as.
