Description

Technical Field

[0001] This utility model relates to the field of integrated ceiling technology, and in particular to an integrated ceiling frame. Background Technology

[0002] The keel frame for integrated ceilings is used to support and fasten the metal panels of the integrated ceiling. In existing keel frames for integrated ceilings, the metal panels are arranged in a tightly fitted manner.

[0003] However, in use scenarios such as factories or shopping malls, the existing installation structure with tightly fitted metal plates is difficult to meet ventilation requirements. Furthermore, in these scenarios, the materials are prone to thermal expansion and deformation, and the tightly fitted metal plates are easily squeezed and deformed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where tightly fitted metal plates cannot meet the requirements for ventilation and deformation prevention, and to propose an integrated ceiling keel frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an integrated ceiling keel frame, including two sets of angle steel, the two sets of angle steel are arranged back to back, the two sets of angle steel are fixedly connected by connecting pieces, and a gap is reserved between the two sets of angle steel, and also includes:

[0007] The clamping piece has a connecting part and an elastic abutment part bent at both ends. The connecting part is fixedly connected to one end of the angle steel, and the elastic abutment part is elastically abutted to the other end of the angle steel.

[0008] Preferably, it also includes an external frame, the lower end of which is integrally formed with a buckle groove, the angle steel and the connecting part are inserted into the buckle groove, and the external frame is used to connect to an external support body.

[0009] Preferably, the connecting part is fixed to the angle steel by welding, and the angle steel is fixed to the connecting piece by riveting.

[0010] Preferably, the angle steel, the connecting part, and the connecting piece are fixed together by riveting.

[0011] Preferably, both ends of the connecting piece are integrally formed with limiting pieces, and the limiting pieces can be bent between the two sets of angle steels.

[0012] Preferably, the elastic abutment portion has a C-shaped structure.

[0013] Preferably, the elastic abutment portion has a wavy structure.

[0014] The integrated ceiling keel frame proposed in this utility model has the following advantages:

[0015] The two sets of angle steel are designed with clamping plates. The elastic abutment part in the clamping plate cooperates with the angle steel to fix the metal plate. A gap is reserved between the two sets of angle steel so that the metal plates no longer stick to each other. While meeting the ventilation requirements, the expansion redundancy of the material is reserved to avoid the metal plate being deformed due to thermal expansion. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1 , Figure 2 , Figure 6 An integrated ceiling keel frame includes two sets of angle steel 1, which are arranged back-to-back and fixedly connected by connecting pieces 5. A gap is reserved between the two sets of angle steel 1. It also includes:

[0026] The clamping piece 2 has a connecting part 3 and an elastic abutting part 4 bent at both ends. The connecting part 3 is fixedly connected to one end of the angle steel 1, and the elastic abutting part 4 is elastically abutting the other end of the angle steel 1.

[0027] Furthermore, refer to Figure 5 It also includes an external frame 7, the lower end of which is integrally formed with a buckle groove 8. Angle steel 1 and connecting part 3 are inserted into the inside of buckle groove 8. The external frame 7 is used to connect to the external support body.

[0028] Furthermore, refer to Figure 1 , Figure 2 The connecting part 3 is fixed to the angle steel 1 by welding, and the angle steel 1 is fixed to the connecting piece 5 by riveting;

[0029] Furthermore, refer to Figure 6 Both ends of the connecting piece 5 are integrally formed with limiting pieces 6. The limiting pieces 6 can be bent between the two sets of angle steel 1. The limiting pieces 6 are used to limit the minimum distance between the two sets of angle steel 1.

[0030] Furthermore, refer to Figure 2 The elastic contact part 4 has a C-shaped structure.

[0031] Working principle:

[0032] During assembly, the two sets of angle steel 1 are arranged according to... Figure 2 As shown, with the angles facing away from each other, place the connecting piece 5 on one side of the plane of the two sets of angle steel 1, and then fix the connecting piece 5 to the two sets of angle steel 1 with rivets. After fixing the connecting piece 5 to the angle steel 1, bend the limiting piece 6 so that the limiting piece 6 enters between the two sets of angle steel 1. The two sides of the limiting piece 6 abut against the two sets of angle steel 1 respectively. The limiting piece 6 is used to limit the minimum distance between the two sets of angle steel 1. Then, weld the connecting part 3 of the clamping piece 2 to the angle steel 1, and make the elastic abutting part 4 of the clamping piece 2 elastically abut against the angle steel 1. Finally, insert the combined part of the angle steel 1 and the connecting part 3 into the buckle groove 8, and fix the external frame 7 to the external support (such as the wall, integrated ceiling bracket, etc.) with expansion screws to complete the assembly of the main body.

[0033] When in use, the edge of the metal plate of the integrated ceiling is inserted between the elastic abutment part 4 and the angle steel 1 to form a fixation. The gap between the two sets of angle steel 1 forms a buffer redundancy for thermal expansion and contraction of the integrated ceiling, and allows airflow to pass through more smoothly.

[0034] Example 2

[0035] To simplify the fixing method between angle steel 1, connecting part 3, and connecting piece 5, refer to... Figure 3 , Figure 4 Angle steel 1, connecting part 3, and connecting piece 5 are fixed together by riveting.

[0036] Furthermore, refer to Figure 4 The elastic contact part 4 has a wave-shaped structure.

[0037] Working principle:

[0038] Reference Figure 4 In order to accommodate riveting, the length of the connecting part 3 is longer in this embodiment, but this makes the inner angle between the connecting part 3 and the clamping piece 2 smaller. In order to obtain sufficient elastic abutment force, the elastic abutment part 4 is set as a wave-shaped structure to increase the contact area.

[0039] Compared with Embodiment 1, during assembly, the angle steel 1, the connecting part 3, and the connecting piece 5 are all fixed by rivets, so that no additional welding steps are required between the connecting part 3 and the angle steel 1, thereby simplifying the fixing method between the angle steel 1, the connecting part 3, and the connecting piece 5.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
