It includes partition wall horizontal keels, limit fasteners, U-shaped ceiling board keels, and F-shaped ceiling board seam clips. By installing the partition wall horizontal keels on the ceiling wall surface and using the limit fasteners as the connecting devices between the partition wall horizontal keels and the U-shaped ceiling board keels, the limit fasteners are clamped on the partition wall horizontal keels to avoid the inconvenience in the operation during the screw fixation process; by setting the F-shaped ceiling board seam clips to fix the ceiling board and increase the stability of the ceiling board, it can adapt to the existence of wind pressure, and the ceiling board will not shake or sway. On the other hand, the F-shaped ceiling board seam clips seal the gap between the ceiling board and the wall surface.

[0020] The following details the present utility model, clearly and completely describes the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a truss ceiling structure without hanging rods through improvement. The technical solution of the present utility model is as follows:

[0022] As Figure 1-2 shown, a truss ceiling structure without hanging rods includes a pair of walls 1. The inner walls of the pair of walls 1 are both threadedly connected with L-shaped steel plates 2 through expansion bolts 6. A pair of connecting rods 5 are fixedly installed at the top end of each L-shaped steel plate 2. A bottom plate 3 is fixedly installed between the pair of L-shaped steel plates 2. The firmness of the expansion bolts 6 is used to place the L-shaped steel plates 2 on the walls, providing stability and safety for the overall device.

[0023] Furthermore, a steel wire rope 7 is fixedly connected between the bottom plate 3 and the connecting rod 5. A rotating shaft 4 is rotatably installed between each L-shaped steel plate 2 and the bottom plate 3. The upper part is fixed at the 1 / 4 position with the steel wire rope 7, reducing the deformation amount of the keel and extending the service life of the device.

[0024] Furthermore, a truss 8 is fixedly installed on the outer peripheral wall of the pair of rotating shafts 4. The pair of trusses 8 are rotatably connected through a movable shaft. A support plate 9 is jointly rotatably installed between the pair of trusses 8 and the bottom plate 3, facilitating installation by workers and improving construction efficiency and quality.

[0025] Furthermore, a triangular strengthening block 10 is fixedly installed at the bottom end of each L-shaped steel plate 2, providing support force for the device and maintaining stability.

[0026] The specific working method is as follows: During the construction of the anchorage section at the ceiling line, if the infill wall is hollow brick, the corresponding position needs to be replaced with solid blocks. There is no need to adopt the primary and secondary keel systems. The force is transmitted to the end anchorage device. The end anchorage device uses expansion bolts 6 to fix the L-shaped steel plate 2 on the wall 1. The bottom plate 3 is placed on the L-shaped steel plate 2. Transverse braces are connected along the radial direction of the corridor. The keels adopt a hinged system. The truss 8 is driven by the rotating shaft 4 to adjust and slide on the bottom plate 3. It belongs to a statically indeterminate system and can produce micro-deformations. The support plate 9 and the steel wire rope 7 are installed to maintain the stability of the device, relieve the temperature stress, and at the same time have sufficient resistance to maintain the overall stability. The steel plate specifications and the number of anchor bolts are selected according to the ceiling volume and the corridor width. The steel plates do not need to be continuously arranged. In addition, triangular strengthening blocks 10 are installed at the bottom of the L-shaped steel plates 2.

[0027] The technical means disclosed in the technical solution of the present utility model are not limited to the technical means disclosed above, but also include technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
