Description

Technical Field

[0001] The utility model relates to the field of keel connection, in particular to a keel connection structure for building steel structures. Background Technique

[0002] In decoration projects such as suspended ceilings and partition walls, the main keel usually serves as the skeleton of the entire structure, playing a role in support and fixation. Therefore, the connection strength of the main keel joints is crucial for the stability of the project. A keel is a building material used to support the shape and fix the structure. The light steel (baked paint) keel suspended ceiling has the effects of light weight, high strength, adaptability to waterproofing, earthquake resistance, dust prevention, sound insulation, sound absorption, constant temperature, etc., and also has the advantages of short construction period and simple construction.

[0003] After retrieval, the Chinese utility model patent CN109208810A, a keel connection structure for building steel structures, includes a keel body and four positioning plates. The four positioning plates are respectively located at the four corners of the keel body. Connecting rings are fixedly connected to the fronts of the two upper positioning plates. Adjusting rods are movably connected to the inner walls of the two connecting rings. Limiting bumps are fixedly connected to the left and right sides of the adjusting rod. Connecting rings are fixedly connected to the fronts of the two lower positioning plates. The adjusting rod is inserted into the connecting ring. In the present invention, the longitudinal fixation of the keel body can be achieved through the setting of the positioning plates. The provided adjusting rods can be adjusted according to the different bone lengths of the keels, ensuring better adjustability of the fixation. The provided fixing plates and installation frames can fix the keel body horizontally.

[0004] The following problems will occur when the existing device is in use: When connecting the keels, usually a connecting piece is required for cooperative connection. However, the connecting piece has a complex structure, weak strength, and a small connecting area, resulting in poor connection stability and increasing the risk of detachment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a keel connection structure for building steel structures to solve the problems raised in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A connecting structure for building steel structure keels, including keels, mounting bracket A, and mounting bracket B. Mounting bracket A and mounting bracket B are juxtaposed and fitted into the keels. On mounting bracket A, a keel is installed through mounting bolt A, and on mounting bracket B, a keel is installed through mounting bolt B. A connecting plate is movably arranged inside mounting bracket B. One side of the connecting plate is connected with a plug rod. Reinforcing blocks are arranged on both mounting bracket A and mounting bracket B. Insert the secondary keel between mounting bracket A and mounting bracket B, push the connecting plate to drive the plug rod into the limiting groove, and one end of the plug rod is inserted into the clamping groove, thereby limiting the secondary keel. A secondary keel is arranged between mounting bracket A and mounting bracket B. The secondary keel is provided with a limiting groove. Insert the secondary keel between mounting bracket A and mounting bracket B, push the connecting plate to drive the plug rod into the limiting groove, and one end of the plug rod is inserted into the clamping groove, thereby limiting the secondary keel and reducing the positioning time of the fixing bolts.

[0007] In a further embodiment, the reinforcing block is set in a V shape to achieve triangular support and increase the structural stability.

[0008] In a further embodiment, the plug rod fits the limiting groove. Mounting holes are provided on the connecting plate, and connecting bolts are arranged on mounting bracket B. The connecting block is limited and fixed by the connecting bolts, and the plug rod fits the limiting groove, thereby reducing the risk of the secondary keel falling off.

[0009] In a further embodiment, a clamping groove is provided on one side of mounting bracket A, and one end of the plug rod is fitted into the clamping groove.

[0010] In a further embodiment, clamping blocks are arranged on both sides inside mounting bracket A and mounting bracket B. The clamping blocks fit the keels. Mounting bolt A and mounting bolt B are respectively arranged on the two clamping blocks, increasing the connection area and making the connection between mounting bracket A, mounting bracket B and the keels closer.

[0011] In a further embodiment, threaded holes are provided on the secondary keel, and fixing bolts are arranged on mounting bracket B. The fixing bolts are adapted to the threaded holes. Mounting bracket A and mounting bracket B are installed and connected to the keels through mounting bolt A and mounting bolt B.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. Fit mounting bracket A and mounting bracket B into the keels, increase the connection area, improve the tensile strength, and the reinforcing blocks increase the connection strength of mounting bracket A and mounting bracket B, avoiding the inclination of the secondary keel.

[0014] 2. Insert the secondary keel between mounting bracket A and mounting bracket B. Push the connecting plate to drive the insertion rod into the limiting groove, and one end of the insertion rod is inserted into the clamping groove, thereby limiting the secondary keel, increasing the connection area between the secondary keel and mounting bracket A and mounting bracket B, improving the connection bearing capacity, reducing the risk of falling off, and performing pre-connection, reducing the positioning time of subsequent fixing bolts and improving the convenience of connection.
