Light keel support system with adjustable structure

The invention discloses a light keel support system with an adjustable structure. The light keel support system comprises multiple pieces of double-C-shaped channel steel. The plurality of double-C-shaped channel steels comprise a first steel body which is horizontally arranged, a second steel body which is connected with the first steel body, and a third steel body which forms a preset included angle with the second steel body; the second steel body and the third steel body are both positioned above the first steel body; the connecting boxes are located between the two adjacent double-C-shaped steel channels, and the connecting boxes are fixedly connected with the two adjacent double-C-shaped steel channels respectively; the supporting rods are fixedly arranged between the first steel body and the third steel body and between the first steel body and the second steel body, and the length of the supporting rods is adjustable, so that the preset included angle is adjustable. According to the light keel support
