detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figures 1-3, a ceiling keel with shock absorption and sound absorption functions includes a main keel 1, an auxiliary keel 2 and a connector 3, the main keel 1 and the auxiliary keel 2 are vertically staggered, and the main keel 1 is C-shaped keel, the top of the connector 3 is provided with a U-shaped bending part 4, the bending part 4 is clamped with the main keel 1, the bottom of the connector 3 is provided with inwardly bent hooks 5 on both sides, and the hook 5 is connected to the auxiliary The keel 2 is clamped, the section of the auxiliary keel 2 is hollow funnel-shaped and filled with sound-absorbing cotton layer 6, the two sides of the auxiliary keel 2 are evenly distributed with through holes 7, the front and rear ends of the auxiliary keel 2 are equipped with end covers 8, the main keel 1 The bottom is provided with a shock-absorbing support 9. The shock-absorbing support 9 includes two steel plates 10 and a sheath 11 installed between the two steel plates 10. The sheath 11 is a polyvinyl chloride sheath. The upper steel plate 10 is connected to the main The bottom of the keel 1 is welded, and a plurality of steel sheets 12 and a plurality of rubber sheets 13 are successively arranged at intervals in the sheath 11.
