The length of the first engagement plate 112 in the extending direction of the rail is D2. The length of the second engaging plate 122 in the extending direction of the rail is D3. The distance between the rear end of the top plate 211 of the first beam 201 and the front end of the top plate 212 of the second beam 202 is D4. In order to ensure that the first clamping groove 110 can move from between the first beam 201 and the second beam 202 to a position where the clamping groove is clamped with the top plate 211 of the first beam 201, d1+d2 < D4. In order to ensure that the first clamping groove 110 and the second clamping groove 120 are respectively clamped with the two cross beams and cannot fall off, D1+D3 is larger than D4.

A gap is left between the second connection plate 121 and the second beam 202 so that the first plate 101 can be moved in the extending direction of the rail, thereby adjusting the position of the first plate 101.

A gap 173 is provided between the second connecting plate 121 and the front end of the top plate 212 of the second beam 202, and the dimension of the gap 173 in the extending direction of the rail is equal to or larger than the dimension of the first engagement plate 112.

The second clamping groove 120 of the second first plate 101 moves to a position to be clamped with the other second cross member 202. The second first plate 101 moves in the direction of the first beam 201 (the first beam 201 may be the aforementioned second beam 202) so that the first slot 110 engages with the first beam 201. The third first board 101, the fourth first board 101 and a greater number of first boards 101 are then installed in sequence.

The second plate 102 is then installed. The second plate 102 has two mounting means:

1. the third engaging groove 130 of the front end 105 of the second plate 102 is engaged with the rear end of the top plate 212 of the second cross member 202 at first, and then the rear end 106 of the second plate 102 is moved downward at an inclination in the direction of the third cross member 203, and the abutment 150 of the rear end 106 of the second plate 102 is moved to a position abutting against the third cross member 203.

2. The front end 105 of the second plate 102 is connected to the second beam 202 by a first connector 141 and the rear end 106 of the second plate 102 is connected to the third beam 203 by a second connector 142.
