The keel frame 1 includes a ground keel 11, a ceiling keel 12, a vertical keel 13 and a frame board 14. The lower end of the side of the frame board 14 is fixedly connected to the ground keel 11, and the upper end of the side of the frame board 14 is fixedly connected to the ceiling keel 12. The cross-section of the ground keel 11 is an inverted "N" shape. The ground of the ground keel 11 is provided with round holes and is fixedly connected to the floor by screws. The ground keel 11 can determine the position of the keel frame 1 and fix it.

[0033] A crossbeam 5 is arranged between the ground keel 11 and the ceiling keel 12. The ceiling keel 12 is a T-shaped light steel keel. Round holes are arranged on the surface of the ceiling keel 12 and fixedly connected to the roof by screws. The ceiling keel 12 is divided into two sections and fixed by welding for easy installation. When the ceiling keel 12 is set into two sections, the vertical keel 13 is more convenient to install. By setting the ceiling keel 12 to a T-shape, the ceiling keel 12 can fix the position of the vertical keel 13.

[0034] The end face of the crossbeam 5 is fixedly connected to the frame plate 14, and the surface of the crossbeam 5 is slidably connected with a vertical keel 13, and the upper end of the vertical keel 13 is slidably connected to the top keel 12. Asbestos boards 2 are arranged on both sides of the vertical keel 13, and positioning nails 21 are rotatably connected to the surface of the asbestos board 2. The vertical keel 13 is a V-shaped light steel keel, and the vertical keels 13 are arranged crosswise in the reverse and forward directions on the surface of the crossbeam 5. The upper end of the vertical keel 13 is provided with a groove and is slidably connected to the top keel 12. The middle section of the vertical keel 13 is provided with a threaded hole at the sharp corner and meshed with the positioning nail 21. The vertical keels 13 are arranged alternately in forward and reverse directions so that the vertical keels 13 are neatly arranged to form a wall to avoid grid-shaped holes in the keels. The intervals between each vertical keel 13 can be adjusted by adjusting the number of the vertical keels 13.

[0035] The positioning nails 21 are threadedly connected to the vertical keel 13. There are two groups of asbestos boards 2 distributed on both sides of the vertical keel 13. A long strip groove 22 is set on the side where the two groups of asbestos boards 2 are close to each other. The corners of the vertical keel 13 are all clamped in the inner side of the long strip groove 22. The positioning nails 21 penetrate the asbestos board 2 and are threadedly connected to the vertical keel 13. The asbestos board 2 has the long strip groove 22 on the surface so that the vertical keel 13 can be neatly and regularly arranged and fixed. The asbestos board 2 can be fixed to the vertical keel 13 through the positioning nails 21.

[0036] A structural plate 3 is provided on the side of the asbestos board 2 away from the vertical keel 13, and the ground keel 11 is wrapped around the outer surface of the lower end of the structural plate 3. Gypsum boards 4 are fixedly connected on both sides of the keel frame 1, and a positioning block 6 is fixedly connected on the inner side of the frame plate 14.

The inner side of the hole groove of the frame plate 14 is filled with polyurethane foam. The frame plate 14 can fix the positions of the ground keel 11 and the ceiling keel 12, so that the keel frame 1 can be more stable. By fixing the frame plate 14 on both sides, the keel frame 1 can be more firm when subjected to impact and vibration.

[0037] A top spring 7 is fixedly connected to the inner side of the positioning block 6, and a top ring 8 is slidably connected to the inner side of the positioning block 6. The positioning block 6 has a square shape, and two cylindrical grooves are arranged at one end of the positioning block 6 close to the vertical keel 13. The top spring 7 is inside the cylindrical groove, and the positioning block 6 plays a guiding and fixing role.

[0038] The end face of the top ring 8 is fixedly connected to the top spring 7, and an expansion screw 9 is sleeved on the inner side of the top ring 8. The top ring 8 has a circular shape, and the top ring 8 slides and engages on the inner side of the cylindrical groove of the positioning block 6. A sliding key is provided on the outer surface of the top ring 8 to prevent it from rotating. A ratchet disk is provided on the end face of the top ring 8. The top ring 8 is pushed by the top spring 7 so that the ratchet disk on the surface of the top ring 8 can engage with the expansion screw 9 to prevent it from reversing.

The expansion screw 9 is fixed to the inside of the wall through the expansion wire 91, and is engaged with the top ring 8 through the locking nut 92 to prevent rotation and loosening. The top ring 8 is pushed by the top spring 7, so that the expansion screw 9 has a tendency to be pulled outward. When the expansion screw 9 is loose on the inside of the wall hole, the top spring 7 pushes the top ring 8 and pushes the expansion screw 9 to move outward to disengage from the loose and enlarged hole to a suitable new position, thereby achieving the effect of anti-vibration fixing.
