Figure 2 When the installation is performed in the state shown and more than two supporting parts are required for support, the length of the telescopic part on each supporting part is independently adjusted according to the inclination angle of the keel part to ensure that the keel parts with different inclination angles are fixed.

Figure 1 When installing in the state shown, after the mounting position of the bracket 5 is fixed and the keel member is fixed between the mounting frame 16 and the sliding plate 17, the sliding plate 17 is made to slide along the inner wall of the sliding seat 4 by rotating the knob 13 and the threaded rod 15, thereby adjusting the lateral position of the keel member.

[0031] The keel member includes a keel body 1 2 and a keel body 2 3, and the keel body 1 2 and the keel body 2 3 are fixedly connected by bolts and nuts; The keel body 1 2 and the keel body 2 3 are fixed vertically to each other, and the keel body 1 2 can be used to lay the ceiling board.

[0032] When the present embodiment is in use, the bracket 5 is first fixed to the bottom of the ceiling 1 by the expansion bolts, and then the threaded tube 8 is rotated along the threaded column 7 according to the installation height of the ceiling board, and the total length of the threaded column 7 and the threaded tube 8 is adjusted, and then the relative position between the slide seat 4 and the connecting frame 9 is adjusted according to the laying angle of the ceiling board, and then the locking cap 23 is used to lock the locking piece 27 and the connecting frame 9. Then, the installation frame 16 is fixed to the bottom of the sliding plate 17, and the keel body 2 3 is inserted into the installation frame 16, and then the installation frame 16 and the keel body 2 3 are fixed by bolts and nuts, and then the keel body 1 2 and the keel body 2 3 are fixed by bolts and nuts, and finally the ceiling board and the keel body 1 2 are fixed; Combination Figure 1-3 According to the different inclination angles of the ceiling 1 and the different laying angles of the ceiling panels, the support part can be adjusted in combination with the actual construction environment to ensure the smooth laying of the ceiling panels. Example

[0033] A rail transit ceiling structure, such as Figures 1 to 8 As shown, in order to improve the convenience and safety of construction, this embodiment makes the following supplements on the basis of embodiment 1: the side wall of the connecting frame 9 is provided with an adsorption groove 19, and the side wall of the locking member 27 is provided with a rectangular groove 20, and the inner wall of the adsorption groove 19 and the rectangular groove 20 is installed with auxiliary mounting parts by magnetic attraction, and the auxiliary mounting parts include an L-shaped plate 24 and a magnet 25, the magnet 25 and the L-shaped plate 24 are fixedly connected, and the magnet 25 and the adsorption groove 19 are adsorbed and fixed, and the through hole opened on one side of the L-shaped plate 24 is rotatably connected with A rotating column 21, and a toothed wheel 18 is welded at one end of the rotating column 21, and a clamping block 22 is welded on the outer wall of one side of the toothed wheel 18, and a second magnet 26 is fixed on the outer wall of the clamping block 22, and the second magnet 26 and the rectangular groove 20 are adsorbed and fixed, and a limiting mechanism is installed on the top of the L-shaped plate 24, and the limiting mechanism includes a clamping tooth 12 and a T-shaped rod 10, and the T-shaped rod 10 is slidably connected to the inner wall of the through hole opened on the surface of the L-shaped plate 24, and the clamping tooth 12 is fixed to the bottom of the T-shaped rod 10 by a screw, and a spring 11 is clamped between the T-shaped rod 10 and the L-shaped plate 24; When the slide 4 needs to be installed between the connecting frame 9 at a certain tilt angle, in the initial stage, the L-shaped plate 24 is fixed to the inner wall of the adsorption groove 19 by the magnet 1 25, and the clamping block 22 is fixed to the inner wall of the rectangular groove 20 by the magnet 2 26, and then the locking piece 27 is rotated along the connecting frame 9. When the slide 4 rotates to the set angle, the clamping tooth 12 is clamped into the outer wall of the toothed wheel 18 by the elastic force of the spring 11, so that the toothed wheel 18 is limited by the clamping tooth 12. After the toothed wheel 18 is limited, the locking cap 23 is also limited at the same time. When the locking cap 23 locks and fixes the locking piece 27, the locking piece 27 can be prevented from shaking relative to the connecting frame 9, thereby ensuring the adjustment accuracy of the angle between the slide 4 and the connecting frame 9. At the same time, there is no need for the locking cap 23 to lift the slide 4 during the locking process, thereby ensuring the safety of construction. When the locking cap 23 is locked, magnet 1 25 and magnet 26 are removed from the adsorption groove 19 and the locking member 27 respectively, so that the entire auxiliary mounting member and the supporting part are separated, which facilitates the subsequent use of the auxiliary mounting member to adjust the angle between the slide seat 4 and the connecting frame 9 on the remaining supporting parts.
