Detailed Description
The present invention will be described in detail with reference to specific examples.
As shown in fig. 1 and 2, the present embodiment includes a baffle plate 1, a bow bar 2, a U-shaped bar 3, and a rib plate 4.
In this embodiment, the partition board 1 is rectangular, and the two sides of the partition board 1 are provided with symmetrical V-shaped concave notches 13, but the concave notches 13 in the present invention are not limited to V-shaped, and may be trapezoidal. The 1 upper end of baffle is equipped with two and goes up notch 11, and 1 lower extreme of baffle is equipped with two notch 12 down, goes up notch 11 and notch 12 down and is the rectangle, and the mutual symmetry in position, and the width of going up notch 11 and notch 12 down slightly is greater than the thickness that two times bow-shaped strip 2 can. The plurality of partition boards 1 are arranged in a linear array.
The arched strip 2 is of an I-shaped strip structure, the middle part of the arched strip 2 is in a shape corresponding to the concave notch 13 of the partition board 1, and when the concave notch 13 is in a V shape, the middle part of the arched strip 2 is also in a V shape. Two bow-shaped strips 2 clamp two sides of the partition board 1 arranged in an array, the bow-shaped strips 2 are attached to the side wall of the partition board 1, and two edges of the bow-shaped strips 2 are bent and inserted into an upper notch 11 and a lower notch 12 which are close to one side of the partition board 1 respectively.
The U-shaped strip 3 is a U-shaped strip structure, the number of the U-shaped strip 3 is two, two bending edges of one U-shaped strip 3 are respectively inserted into the two upper notches 11, and two bending edges of the other U-shaped strip 3 are inserted into the two lower notches 12.
The rib plate 4 corresponds to the middle bending shape of the bow-shaped strip 2, the rib plate 4 is triangular in the embodiment, and the triangular rib plate 4 is clamped into the bending part of the bow-shaped strip 2, so that the whole beam is just in a square structure.
