Therefore, these or other orientation terms should not be construed as restrictive terms.

[0026] Reference Figures 1 to 3 As shown in, what is disclosed in the embodiment of the present utility model is:

[0027] A gypsum ceiling board installation structure, including at least one group of main keels 1 for hanging on a floor slab, a gypsum board 2 arranged at the bottom of the main keel 1, and further including a pre - suspension connecting piece 3. Both ends of the pre - suspension connecting piece 3 are detachably connected to the gypsum board 2 and the main keel 1 respectively, so as to limit the gypsum board 2 at an installation position relative to the main keel 1. When installing the gypsum board 2, first, through the pre - suspension connecting piece 3, the gypsum board 2 is limited at an installation position relative to the main keel 1, and then the gypsum board 2 is formally installed and fixed through other connecting pieces (such as bolts). Thus, the installation process no longer requires other workers to support the gypsum board 2, thereby reducing the labor intensity of workers during the installation process.

[0028] A pre - tightening block 4 is arranged at the lower end of the pre - suspension connecting piece 3. A pre - tightening groove 5 extending in the direction of the main keel 1 is formed on the upper end surface of the gypsum board 2. The pre - tightening groove 5 can allow the pre - tightening block 4 to slide in along a predetermined direction. Specifically, the pre - tightening block 4 is an inverted "T" - shaped block, the pre - tightening groove 5 matches the pre - tightening block 4, and the pre - tightening groove 5 extends from the side wall of the gypsum board 2 to the installation position of the gypsum board 2 relative to the main keel 1, so that the pre - tightening block 4 can slide into / out of the pre - tightening groove 5 from the side wall of the gypsum board 2. The structure is simple and the disassembly and assembly are convenient.

[0029] One side of the main keel 1 is provided with a receiving groove 6, and the upper end of the pre-suspension connecting member 3 is provided with a connecting portion 13 that can slide along a predetermined direction and snap into the receiving groove 6. It should be noted that in this embodiment, as Figure 1 shown, the main keel 1 is a channel steel main keel 1, which itself has the receiving groove 6 (i.e., the slot opened in the channel steel main keel 1), which is a commonly used and commercially available existing product in the art, so that the main keel 1 in this embodiment does not need to be additionally processed with the receiving groove 6.

[0030] The pre-suspension connecting member 3 is provided with a positioning mechanism, and the positioning mechanism is used to limit the connecting portion 13 from sliding out of the receiving groove 6 after the connecting portion 13 snaps into the receiving groove 6. Specifically, the positioning mechanism includes a positioning pin 7 that is vertically movably arranged on the pre-suspension connecting member 3. The lower end of the positioning pin 7 penetrates downward through the connecting portion 13, and a positioning hole 8 for cooperating with the positioning pin 7 is opened on the inner wall of the receiving groove 6 of the main keel 1. An elastic member 9 is arranged on the positioning pin 7. The elastic member 9 is a compression spring, which is located in the connecting portion 13 and sleeved on the positioning pin 7. The elastic member 9 applies a force to the positioning pin 7 to extend into the positioning hole 8 or prevent it from protruding out of the positioning hole 8. An inclined resisting surface 11 is arranged at the position where the lower end of the positioning pin 7 penetrates through the connecting portion 13. The inclined resisting surface 11 is used to resist the lower end of the main keel 1 when the pre-suspension connecting member 3 slides in the predetermined direction, so that the positioning pin 7 rises against the force of the elastic member 9. Specifically, when the pre-suspension connecting member 3 slides along the predetermined direction, its upper connecting portion 13 snaps into the receiving groove 6. During the snapping process, the inclined resisting surface 11 at the lower end of the positioning pin 7 resists the lower end of the main keel 1. Under the action of a continuous external force, the positioning pin 7 slides upward against the force of the compression spring until the lower end of the main keel 1 no longer resists the inclined resisting surface 11. At this time, the connecting portion 13 can be completely snapped into the receiving groove 6 (during this process, the lower end of the positioning pin 7 resists the lower end surface of the receiving groove 6, and the positioning pin 7 cannot descend and reset). When the connecting portion 13 is completely snapped into the receiving groove 6, the lower end of the positioning pin 7 cooperates with the positioning hole 8. At this time, under the action of the compression spring, the positioning pin 7 descends for resetting and cooperates with the positioning hole 8, thereby restricting the connecting portion 13 from sliding out of the receiving groove 6 again.

[0031] The side wall of the positioning pin 7 is provided with an adjusting member 10 that penetrates outward through the connecting portion 13. The staff can control the adjusting member 10 to drive the positioning pin 7 to move upward against the acting force of the compression spring, so that the positioning pin 7 is disengaged from the positioning groove. At this time, the staff can slide the pre-suspension connecting member 3, so that the pre-suspension connecting member 3 is no longer connected to the main keel 1; the pre-suspension connecting member 3 can be disassembled.

[0032] The positioning hole 8 is a weight-reducing hole extending along the length direction of the main keel 1; further, a tape 12 is pasted on the pre-tightening groove 5. When the pre-suspension connecting member 3 does not slide into the pre-tightening groove 5, the tape 12 can prevent foreign matters such as dust from entering the pre-tightening groove 5.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
