Description

Technical Field

[0001] The utility model relates to the technical field of arch type ceiling, in particular to an arch type ceiling structure without suspender bars. Background Technique

[0002] At present, the number of functional rooms in public buildings has increased. In order to improve the space utilization rate, in special public buildings such as hospitals, the pipeline systems inside the ceiling are usually very complex, including not only conventional air conditioning, ventilation, and smoke exhaust systems, but also medical gas supply pipelines, etc. The integration of these systems often makes the space in public areas such as corridors very narrow.

[0003] After retrieval, a Chinese patent with the publication number CN217537523U discloses a ceiling structure. This ceiling structure includes a steel structure, a keel structure, a bracing bar, and a fixing plate. The keel structure includes a plurality of longitudinally parallel keels. The keels at both ends are respectively fixed to the side walls of the steel structure. The bracing bar connects adjacent keels, and then a fixing plate is arranged outside the steel structure and the keel structure, so as to form a connection with the steel structure through the arrangement of the keel structure and the bracing bar.

[0004] Based on the above retrieval and in combination with the prior art, it is found that;

[0005] Although the above retrieved patent is convenient for construction, there are problems of unclear interface division and at the same time, the suspender bars need to bear a greater load, which puts higher requirements on the construction quality of the post-embedded bars of the suspender bars. If the construction quality control is improper, potential safety hazards may be left, so there are certain limitations. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model proposes an arch type ceiling structure without suspender bars, which avoids potential safety hazards caused by construction quality problems and improves the construction efficiency.

[0007] The technical solution to achieve the purpose of the utility model is: an arch type ceiling structure without suspender bars, including a pair of walls. The inner walls of the pair of walls are both threadedly connected with L-shaped steel plates through expansion bolts, and a bottom plate is fixedly installed between the pair of L-shaped steel plates.

[0008] Preferably, arch-shaped support rods are fixedly installed between the L-shaped steel plates and the bottom plate.

[0009] Preferably, elastic bonding materials are filled between the arch-shaped support rods and the L-shaped steel plates and the bottom plate.

[0010] Preferably, a reinforcing block is fixedly installed at the bottom of the L-shaped steel plate, and a support frame is fixedly installed between the bottom plate and the arch-shaped support rods.

[0011] Compared with the prior art, the remarkable advantages of the present utility model are:

[0012] First: The end of the utility model adopts an elastic bonding material, which can adapt to temperature changes, avoid deformation caused by temperature stress, use an arch support to reduce deformation, and transfer the primary and secondary keels and its own gravity to the end anchoring device.

[0013] Second: The end of the utility model uses a steel plate plus expansion anchor bolts to nail on the solid wall without a hanging rod structure, which improves the stability of the device, extends the service life of the device, has high construction efficiency, clear interfaces, reduces cross-construction, has high construction quality, and small deformation.

[0014] It solves the problem that the existing interface division is not clear, which will cause the hanging rod to bear a greater load. If the construction quality control is improper, potential safety hazards may be left. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following details the present utility model, and 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 of 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 an arch-shaped ceiling structure without a hanging rod through improvement. The technical solution of the present utility model is:

[0022] As Figure 1-2 shown, an arch-shaped ceiling structure without a hanging rod 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 5. A bottom plate 3 is fixedly installed between the pair of L-shaped steel plates 2. Using a steel plate plus expansion anchor bolts to nail on the solid wall 1 without a hanging rod structure improves the stability of the device.

[0023] An arch-shaped support rod 4 is fixedly installed between the L-shaped steel plate 2 and the bottom plate 3. By using arch-shaped support, deformation is reduced, and the primary and secondary keels and its own gravity are transmitted to the end anchoring device.

[0024] An elastic bonding material 6 is filled between the arch-shaped support rod 4, the L-shaped steel plate 2 and the bottom plate 3 to prevent the device from deforming and avoid leaving potential safety hazards.

[0025] A reinforcing block 8 is fixedly installed at the bottom of the L-shaped steel plate 2, and a support frame 7 is fixedly installed between the bottom plate 3 and the arch-shaped support rod 4, improving the overall safety and stability of the device.

[0026] The specific working method is as follows: construct the anchoring section at the ceiling line. The end anchoring device uses expansion bolts to fix the L-shaped steel plate 2 on the wall 1. The L-shaped steel plate 2 is fixed on the wall surface through expansion bolts 5. When the infill wall is hollow brick, the corresponding position needs to be replaced with solid block; change from anchoring on the ceiling to anchoring on the arch-shaped member. An elastic bonding material 6 is filled between the arch-shaped support rod 4, the L-shaped steel plate 2 and the bottom plate 3 to ensure shrinkage deformation; in addition, a support frame 7 is fixedly installed between the bottom plate 3 and the arch-shaped support rod 4 to improve the stability. Select the steel plate specification and the number of anchor bolts according to the ceiling volume and the corridor width. The steel plates do not need to be arranged continuously.
