Specifically, the first light partition plate 31 and the second light partition plate 32 are respectively disposed on two sides of the H-shaped steel beam 21 along the first direction, the lower end of the first light partition plate 31 extends into the first groove-shaped space 23, and the upper end of the second light partition plate 32 extends into the second groove-shaped space 23. The first wing plate 211 and the second wing plate 212 may serve as a stopper to limit the displacement of one end of the light-weight partition 3 located in the groove-shaped space. The width of the first groove-shaped space 23 and the second groove-shaped space 23 is substantially the same as the thickness of the first lightweight partition 31, and it should be noted that the thickness refers to the distance between two opposing surfaces having a large area of the sheet-like or block-like object. The thickness of the lightweight partition 3 refers to the distance between two large-area faces of the partition, i.e., the distance between the left and right side faces as shown in fig. 5. The width of the groove-shaped space refers to a distance between the first wing plate 211 and the second wing plate 212. The portion of the light partition 3 near the end can be well clamped with the H-shaped steel beam 21 through good adaptation of the size. As shown in fig. 3a, a light partition plate 3 is arranged between every two adjacent H-shaped steel beams 21, and the upper and lower ends of the light partition plate 3 are fixedly connected with the H-shaped steel beams 21 by being clamped with the groove-shaped spaces of the H-shaped steel beams 21, so that the light partition plate 31 is prevented from tilting, and the light partition plate 31 is fixedly connected with the side wall 1.

The plurality means two or more. Specifically, the number of the first grooves 12 is determined by the number of the connecting pieces 2, for example, as shown in fig. 2a, one connecting piece 2 is disposed in the air duct 11, and two first grooves 12 are required to be disposed for one connecting piece 2, that is, one first groove 12 is correspondingly connected to one end of the connecting piece 2. The specific position of the first groove 12 is also determined by the position of the connecting piece 2, in the construction process, the first groove 12 is formed at the preset height of the air duct 11, the extending direction of the first groove 12 is perpendicular to the first direction, that is, the first groove 12 extends from the inner wall surface of the side wall 1 to the outer wall surface, but does not penetrate through the side wall, that is, the thickness of the first groove 12 is smaller than that of the side wall 1. As shown in fig. 3a, the length extending direction (the left and right direction shown in fig. 3 a) of the connecting element 2 is perpendicular to the first direction, so the heights of the two first grooves 12 correspondingly connected to the connecting element 2 should be substantially the same, so as to effectively avoid the connecting element 2 being placed in the first grooves 12 to be inclined due to the different heights. The two ends of the connecting piece 2 respectively correspondingly extend into the first grooves 12 and are abutted against the first grooves 12.

Specifically, one side of the longitudinal section of the angle steel 22 is parallel to the first direction. The end face of the first angle steel 221 close to the light partition plate 3 is in contact with the left end face of the light partition plate 3, the end face of the second angle steel 222 close to the light partition plate 3 is in contact with the right end face of the light partition plate 3, and the light partition plate 3 is clamped between the first angle steel 221 and the second angle steel 222, so that the overall rigidity and strength of the light partition plate 3 are improved, and the fixed connection between the light partition plate 3 and the side wall 1 is further enhanced.

Specifically, the second grooves 13 and the third grooves 14 have substantially the same shape and size, two second grooves 13 are correspondingly disposed on each first angle 221, and two third grooves 14 are correspondingly disposed on each second angle 222. As shown in fig. 6, the first angle iron 221 is located on the left side of the light weight partition board 3, and correspondingly, the second groove 13 is also located on the left side of the light weight partition board 3, and similarly, the third groove 14 is located on the right side of the light weight partition board 3.

As shown in fig. 3a, the second concave groove 13 abuts on the end of the first angle 221, and the third concave groove 14 abuts on the end of the second angle 222. The abutting means that the end of the first angle 221 is in contact with and abuts against the wall surface of the second groove 13 to form a close contact, and the end of the second angle 222 is in contact with and abuts against the wall surface of the third groove 14 to form a close contact. Specifically, the end of the first angle steel 221 extends into the second groove 13 to form a fixed connection with the sidewall 1, and the end of the second angle steel 222 extends into the third groove 14 to form a fixed connection with the sidewall 1.

In some embodiments, as shown in fig. 3a, the angle steel 22 is disposed between two H-shaped steel beams 21 spaced apart in the first direction. Specifically, the upper and lower end portions of the light-weight partition plate 3 are fixedly connected with the H-shaped steel beam 21, so that the end portion of the light-weight partition plate 3 has good connection rigidity, and the area with weaker rigidity of the light-weight partition plate 3 is located between the two end portions, and the area between the end portions of the light-weight partition plate 3 needs to be reinforced. Because a light partition plate 3 is arranged between every two adjacent H-shaped steel beams 21, the angle steel 22 needs to be arranged between every two adjacent H-shaped steel beams 21, and the effect of reinforcing the light partition plate 3 is achieved.
