[0042] Reference Figures 1 to 4 , the second fixing member 92 is a groove-shaped structure, the second fixing assembly 9 includes a third connecting plate 923, and a first connecting plate 921 and a second connecting plate 922 arranged on both sides of the third connecting plate 923, the third connecting plate 923 is arranged vertically, the first connecting plate 921 and the second connecting plate 922 are arranged horizontally, and the first connecting plate 921, the second connecting plate 922 and the third connecting plate are integrally formed. In this embodiment, the first connecting plate 921 is provided with a first fixing hole 9211 for the suspension rod 101 to pass through, and the first connecting plate 921 is fixedly connected to the suspension rod 101 by nuts on both sides. The second connecting plate 922 is provided with a second fixing hole 9221 for the bolt to pass through, and the second connecting plate 922 is bolted to the first fixing member 91. In this embodiment, the first fixing hole 9211 and the second fixing hole 9221 are located on the same vertical line, which is convenient for the force of the second connecting member to improve the stability of the installation of the keel frame 2.

[0043] Reference Figures 2 to 4The keel frame 2 includes a main keel 21, a secondary keel 22 and a main-secondary keel connector 23. A plurality of main keels 21 are provided, and a plurality of main keels 21 are arranged horizontally at intervals along the X-axis direction.

The keel frame 2 can be made of wood, aluminum alloy profiles, light steel and other materials, and this embodiment does not limit the specific material of the keel frame 2. In this embodiment, the main keel 21, the secondary keel 22 and the primary-secondary keel connecting member 23 are all made of light steel material, and the main keel 21 and the secondary keel 22 are both groove-type structures. The groove of the secondary keel 22 is bent to have a limiting groove, one end of the primary-secondary keel connecting member 23 is clamped with the limiting groove of the secondary keel 22, and the other end of the primary-secondary keel connecting member 23 is bent around the main keel 21, thereby fixing the main keel 21 and the secondary keel 22 in connection.

[0044] Reference Figure 3 and Figure 4 It is worth noting that the installation of the main keel 21 and the secondary keel 22 is completed on the first floor slab 12, so as to reduce the amount of aerial work of the staff, reduce the labor intensity of the staff, and improve the installation efficiency of the hoisting structure.

[0045] Reference Figure 3 and Figure 4 The first fixing member 91 includes a fixing plate 911, a first fixing bolt 912 and a first fixing nut. The fixing plate 911 includes a fixing slot 9111 and a connecting ear plate 9112. The fixing slot 9111 and the connecting ear plate 9112 are integrally formed. The fixing slot 9111 is used to accommodate the main keel 21. The slot side wall of the fixing slot 9111 is provided with a through hole for the first fixing bolt 912 to pass through. The first fixing bolt 912 is connected with the first fixing nut to tighten the fixing slot 9111 and the main keel 21. The connecting ear plate 9112 is horizontally arranged, and the connecting ear plate 9112 is arranged opposite to the notch of the fixing slot 9111. The connecting ear plate 9112 is provided with an ear plate through hole, and the connecting ear plate 9112 is bolted to the second fixing member 92 through the ear plate through hole. That is, through the matching relationship between the fixing groove 9111 and the first fixing bolt 912 , the first fixing member 91 is clamped tightly to the main keel 21 to ensure the connection strength between the first fixing member 91 and the main keel 21 .

[0046] Reference Figure 3 and Figure 4, there are several hoisting assemblies 4, and several hoisting assemblies 4 are detachably connected to the main keel 21 at intervals. The hoisting assemblies 4 are used to connect with the lifting device 7, and the lifting device 7 is used to lift the keel frame 2 to the suspension rod assembly 1. In this embodiment, the hoisting assembly 4 includes a hoisting plate 41, a hoisting bolt 42 and a hoisting nut. The hoisting plate 41 is bent from a light steel plate, so that the hoisting plate 41 is provided with a mounting groove for accommodating the main keel 21, the hoisting plate 41 is provided with a hoisting installation hole 43 for the hoisting bolt 42 to pass through, the main keel 21 is provided with a connecting hole 211 for the hoisting bolt 42 to pass through, and the ceiling bolt is passed through the hoisting installation hole 43 and the connecting hole 211 and then connected with the hoisting nut; thereby fixing the hoisting assembly 4 and the main keel 21 together to improve the connection strength between the hoisting assembly 4 and the main keel frame 2, and improve the stability of the keel hoisting process.

[0047] Reference Figure 5 and Figure 6 , there are several lifting devices 7. In this embodiment, there are four lifting devices 7. The four lifting devices 7 are arranged at the four corner areas of the second floor 13 to lift the keel frame 2 to the designed installation position. The lifting device 7 includes a winch 72 and a fixed pulley 71. The winch 72 is fixed on the first floor 12, and the fixed pulley 71 is fixed at the bottom of the second floor 13. After the traction rope 73 of the winch 72 is wound around the fixed pulley 71, the traction rope 73 is passed through the connecting hole on the lifting plate 41, and the traction rope 73 is tied and fixed to the lifting plate 41. Thus, the keel assembly is lifted to the designed installation position through the four lifting devices 7.

[0048] Reference Figure 5 and Figure 6 In order to facilitate the installation of the keel frame 2, the ceiling structure also includes a guide assembly 8, which includes a universal wheel 81 and a guide connector 82. The universal wheel 81 is rotatably connected to the guide connector 82; the guide connector 82 is detachably connected to the keel frame 2, and the universal wheel 81 is used to abut against the wall 14. In this embodiment, the guide connector 82 is tied and fixed to the main keel 21; so that after the staff installs the keel frame 2, the guide assembly 8 can be removed from the keel frame 2 for next use. That is, by installing the guide assembly 8 on the side wall of the keel frame 2, the friction between the keel frame 2 and the wall 14 can be reduced during the installation of the keel frame 2, thereby facilitating the staff to install the keel frame 2.

[0049] Reference Figure 5 and Figure 6The limiting assembly 6 includes limiting strips 61 that are relatively arranged, and the two limiting strips 61 are located on the same horizontal plane. The limiting strips 61 are used to be fixedly connected to the wall 14. The limiting strips 61 abut against the secondary keel 22 of the keel frame 2, and the limiting strips 61 are used to support the keel frame 2. In this embodiment, the limiting strips 61 are wooden strips, and the limiting strips 61 are fixedly connected to the wall 14 by nails, so that the limiting strips 61 have a supporting effect on the keel frame 2. At the same time, the staff installs the elevator on the first floor 12, and makes the supporting surface of the elevator abut against the secondary keel 22 of the keel frame 2, so that the elevator has a supporting effect on the keel frame 2, further improving the stability of the keel frame 2.

[0050] By setting the limit assembly 6 to temporarily support the keel frame 2, on the one hand, the stability of the keel frame 2 in mid-air is improved, so that the staff can fix the suspension rod 101 and the keel frame 2, reduce the labor intensity of the staff, and improve the installation efficiency of the suspension rod 101 structure. On the other hand, the limit bar 61 of the limit assembly 6 also has a leveling effect. When the keel frame 2 abuts against the limit bar 61, the limit bar 61 has a horizontal leveling effect on the keel frame 2; thereby reducing the leveling steps of the fastening nut 102 on the suspension rod 101, thereby further reducing the workload of the staff in mid-air, reducing the work intensity of the staff, and improving the installation efficiency of the ceiling structure.

[0051] Reference Figure 7 and Figure 8 When the keel frame 2 is hoisted to the designed position, the keel frame 2 is set directly below the boom assembly 1. The staff connects the keel frame 2 to the boom assembly 1 through the fixing assembly 9. Reference Figure 7 and Figure 8 , the fastening nut 102 on the suspension rod 101 sets the second fixing member 92 above the first fixing member 91, so that there is an avoidance gap between the second fixing member 92 and the second fixing member 92. Subsequently, the staff releases the limiting effect of the fastening nut 102 on the second fixing member 92, so that the second connecting plate 922 of the second fixing member 92 abuts against the connecting ear plate 9112 of the first fixing member 91. At this time, the ear plate through hole of the connecting ear plate 9112 and the second fixing hole 9221 on the second connecting plate 922 are located on the same straight line, so that the connecting ear plate 9112 and the second connecting plate 922 can be fixed by bolts.

[0052] The panel layer 3 is composed of several panels 31, which are laid on the keel frame 2 to form the panel 31, and the panel 31 is fixedly connected to the secondary keel 22. The panel 31 can be a plate structure such as a gypsum board, a metal plate, an aluminum gusset plate, etc., and the specific structure of the panel 31 is not limited in this embodiment.

[0053] The implementation principle of a building ceiling structure and a construction method thereof in the embodiment of the present application is as follows: The staff first installs the suspension rod 101 at the bottom of the floor slab, and bolts the suspension rod 101 to the second fixing member 92 of the fixing assembly 9. Then, the staff installs the keel frame 2 on the ground, and fixes the first fixing member 91 of the fixing assembly 9 to the main keel 21; then, the staff hoists the installed keel frame 2 as a whole to the designated installation position through the hoisting assembly 4, and bolts the first fixing member 91 of the fixing assembly 9 to the second fixing member 92, thereby completing the connection between the keel frame 2 and the suspension rod 101. Finally, the staff fixes the panel layer 3 to the keel frame 2 to complete the installation of the ceiling structure.

[0054] That is, through the coordinated cooperation of the lifting assembly 4 and the fixing assembly 9, the staff can complete most of the splicing and installation work of the ceiling structure on the ground, and then lift the keel frame 2 to the installation position and fix the keel frame 2 to the suspension rod 101; thereby reducing the workload of the staff in mid-air, thereby reducing the labor intensity of the staff and improving the installation efficiency of the ceiling structure.

This makes it convenient for the staff to install the second fixing member 92 and connect the suspension rod 101 and the second fixing member 92.

[0057] Reference Fig.10 and Fig.11 At the same time, when the first fixing member 91 and the second fixing member 92 are connected, if the installation distance between the suspension rod 101 and the first fixing member 91 in the local area is different from the designed distance due to installation errors, the installation and fixation of the keel frame 2 will be affected.
