[0079] Reference Figure 3 and Figure 4 The keel conversion layer 20 further comprises a keel angle steel 23, which comprises a horizontal plate 231 and a vertical plate 232. One end of the horizontal plate 231 is connected with one end of the vertical plate 232, and the horizontal plate 231 and the vertical plate 232 have a preset angle therebetween. The horizontal plate 231 is detachably mounted at the bottom of the main keel purlin 21, and the top of the suspender 22 is detachably mounted at the vertical plate 232. The suspender 22 and the main keel purlin 21 can be fixed to each other by the keel angle steel 23, and the suspender 22 is fixedly mounted below the main keel purlin 21.

[0080] Reference Figure 7Further, the keel conversion layer 20 further comprises a secondary keel purlin 24, which is detachably installed below the primary keel purlin 21 and staggered with the primary keel purlin 21. Preferably, the length extension direction of the primary keel purlin 21 is perpendicular to the length extension direction of the secondary keel purlin 24. Both ends of the secondary keel purlin 24 are respectively provided with a hanger 22.

[0081] Referring to Figure 10 , Figure 11 and Figure 12 In some variant embodiments, the hanger 22 is provided with a receiving groove 41 corresponding to the position of the limiting protrusion 221, the lower end of the limiting protrusion 221 is rotatably installed at the bottom of the opening of the receiving groove 41; the inner side of the limiting protrusion 221 is located in the receiving groove 41, and the top of the inner side extends upward to form an abutting block 42; the bottom of the outer side of the limiting protrusion 221 is an inclined guide surface 43, and the top is a limiting plane 44.

[0082] The number of the limiting protrusions 221 and the receiving grooves 41 is both two, and the keel conversion layer 20 further comprises a resilient member 45 arranged between the two inner sides of the two limiting protrusions 221. Preferably, the resilient member 45 is a spring. The top of the limiting groove 31 is provided with a limiting opening 311, the width of which is smaller than the width of the limiting groove 31, and in the width direction, the bottom plate 30 of the top of the limiting groove 31 extends to the direction of the limiting opening 311 and forms two limiting plates 32 on both sides of the limiting opening 311.

[0083] When assembling the hanger 22 and the bottom plate 30, in the process of inserting the hanger 22 into the limiting groove 31, the limiting plates 32 abut against the inclined guide surface 43 and push the limiting protrusion 221 to rotate in the direction of the receiving groove 41; after the hanger 22 is inserted into the limiting groove 31 to a preset depth, the top of the limiting protrusion 221 passes the limiting plates 32, the resilient member 45 pushes the limiting protrusion 221 to rotate in the direction away from the receiving groove 41, the limiting protrusion 221 enters the limiting groove 31, and the limiting plane 44 is adapted to abut against the limiting plates 32.

[0084] After the resilient member 45 pushes the top of the limiting protrusion 221 to move to a preset position in the direction away from the receiving groove 41, the abutting block 42 abuts against the inner wall of the receiving groove 41 to limit the movement range of the limiting protrusion 221.

[0085] Referring to Figure 10The top of the abutment block 42 extends away from the receiving groove 41 to the outside of the lifting rod 22 to form a pressing block 421. Pressing the pressing block 421 can cause the limiting protrusion 221 to rotate relative to the rod body 222 into the receiving groove 41. For example, when it is necessary to remove the lifting rod 22 from the bottom plate 30, pressing the pressing block 421 causes the limiting protrusion 221 to move into the receiving groove 41, so that the limiting protrusion 221 retracts into the receiving groove 41, thereby allowing the lifting rod 22 to be removed from the limiting groove 31.

[0086] refer to Figure 13 According to another aspect of this application, a method for installing the prefabricated ceiling panels described in the above embodiments is further provided, specifically including:

[0087] 101: After the top of the connecting seat 12 is fixedly connected to the bottom of the steel grid 11 on the ground to form the top steel frame layer 10, the top steel frame layer 10 is installed at a preset position on the top of the building.

[0088] 102: On the ground, fix the top of the rod 222 of the keel conversion layer 20 to the main keel purlin 21. After inserting the two limiting protrusions 221 of the hoisting component 223 into the limiting groove 31 along the length direction of the limiting opening 311 of the limiting groove 31 at the top of the bottom plate 30, rotate the two limiting protrusions 221 in the limiting groove 31 by a preset angle so that the two limiting protrusions 221 respectively engage with the two limiting plates 32 on both sides of the limiting opening 311.

[0089] 103: Increase the height of the keel conversion layer 20 and the bottom plate 30, and fix the top of the rod 222 to the bottom of the connecting seat 12.

It should also be noted that when the two limiting protrusions 221 and the limiting grooves 31 are engaged with each other, the engagement is made more convenient by inserting first and then rotating.
