The adhesive in this embodiment is a polyurethane adhesive. It is worth noting that the first profile 13, the second profile 23 and the third profile 33 of this embodiment have the same structure, but the size and size are different. Specifically, the transverse outer plate 11 and the transverse inner plate 12 are both provided with bends, and the first glue groove 131 on the first profile 13 corresponds to the bend of the transverse outer plate 11 and the bend of the transverse inner plate 12, and the first profile 13 is fixedly connected to the bend of the transverse outer plate 11 and the bend of the transverse inner plate 12.
