It is widely used in hotels, airport terminals, passenger stations, train stations, theaters, shopping malls, factories, office buildings, renovation of old buildings, interior decoration, ceilings, and other places. Currently, keels are required for fixing and supporting in building construction. Two keels need to be fixed together, thus requiring a connecting device. Existing steel structure keel connection structures are mostly fixed by welding, which is inconvenient for disassembly. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a steel structure keel connection device for buildings.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A steel structure keel connection device includes a first keel, a support plate on the outer surface of the first keel, an mounting plate fixedly connected to the bottom of the support plate, and a positioning plate fixedly connected to the top of the support plate; a connecting rod is movably connected inside the positioning plate, a connecting plate is fixedly connected to one end of the connecting rod, a support rod is fixedly connected to the top of the connecting rod, a connecting shaft is movably connected inside the support rod, a fixing plate is fixedly connected to the outer surface of the connecting shaft, and the end of the fixing plate away from the support rod is movably connected to one side of the connecting plate.

[0006] Preferably, there are two mounting plates and two positioning plates, which are respectively located on both sides of the first keel.

[0007] Preferably, the support rod is movably connected to one side of the positioning plate, the connecting plate is movably connected to one side of the first keel, and the connecting plate is located at the top of the support plate.

[0008] Preferably, a second keel is provided on the top of the connecting plate, and the fixing plate is an L-shaped plate located on the outer surface of the second keel.

[0009] Preferably, a limiting plate is movably connected inside the connecting plate, a movable plate is fixedly connected to one side of the limiting plate, and a baffle is fixedly connected to one side of the movable plate.

[0010] Preferably, the baffle is movably connected to one side of the connecting plate and the second keel, and the end of the baffle away from the moving plate is movably connected to the top of the second keel.

[0011] Preferably, a spring is fixedly connected inside the connecting plate, and the spring is fixedly connected to one side of the limiting plate.

[0012] Preferably, two springs are provided, with the two springs located on opposite sides of the movable plate, and the length of the limiting plate is greater than the length of the movable plate.

[0013] Preferably, the mounting plate, positioning plate, connecting plate, fixing plate and connecting rod are all provided with threaded holes, and bolts are provided inside the threaded holes.

[0014] Preferably, there are two connecting rods, the length of which is greater than the length of the positioning plate, and two support rods are provided at the top of each connecting rod, with the fixing plate movably connected between the two support rods.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The present invention proposes a steel structure keel connection device for buildings. By setting a fixing plate, the fixing plate and the support rod are movably connected by a connecting shaft. In use, the fixing plate is first rotated to the side away from the connecting plate, and the second keel is placed on top of the connecting plate. At this time, the fixing plate is rotated so that the fixing plate is located on the outer surface of the second keel, and the end of the fixing plate away from the support rod is located on the side of the connecting plate. The bolts are rotated to the threaded holes in the fixing plate and the connecting plate to fix the fixing plate. Then, the two keels are connected by the fixing plate. When disassembling, the second keel can be removed by rotating the fixing plate. The structure is simple and easy to install and disassemble.

[0017] 2. The present invention proposes a steel structure keel connection device for buildings. By setting a support plate, a positioning plate and an installation plate are respectively set at the top and bottom of the support plate. When connecting the first keel and the second keel, the support plate is moved to fit onto the first keel, so that the support plate is located at the connection point. At this time, the installation plate is fixed. During installation, the connecting plate is moved to the top of the support plate, so that the connecting rod is located in the positioning plate and fixed. After installation, the second keel is fixed to the connecting plate. This allows the second keel to be fixed to different sides of the first keel by moving the connecting plate without disassembling the support plate, achieving the purpose of easy adjustment. The operation is simple and convenient.

[0018] 3. The present invention proposes a steel structure keel connection device for buildings. By setting a baffle, the baffle is movably connected to one side of the connecting plate. When fixing the second keel, the baffle is pulled outward from the connecting plate, causing the moving plate and the limiting plate to slide inside the connecting plate. The limiting plate compresses the spring, increasing the distance between the baffle and the connecting plate. At this time, the second keel can be placed on top of the connecting plate. Then, the baffle is released. Due to the elasticity of the spring, the limiting plate pulls the baffle to one side of the connecting plate, so that the baffle is located on one side of the second keel, thereby positioning the second keel on top of the connecting plate. This reduces the movement of the keel during fixing and provides good stability. Attached Figure Description

[0027] In a preferred embodiment of the present invention, two mounting plates 3 and two positioning plates 4 are provided. The two mounting plates 3 and two positioning plates 4 are respectively located on both sides of the first keel 1. The support plate 2 is fixed on the first keel 1 by the mounting plates 3, and the connection structure is fixed by the positioning plates 4.

[0028] In a preferred embodiment of the present invention, the support rod 7 is movably connected to one side of the positioning plate 4, and the connecting plate 6 is movably connected to one side of the first keel 1. The connecting plate 6 is located on the top of the support plate 2, so that the connection structure is divided into two parts: the support plate 2 and the connecting plate 6, which facilitates installation and disassembly.

[0029] In a preferred embodiment of the present invention, a second keel 10 is provided on the top of the connecting plate 6, and the fixing plate 9 is an L-shaped plate located on the outer surface of the second keel 10. The fixing plate 9 is fixed on the connecting plate 6 by rotating the fixing plate 9, which is easy to operate.

[0030] In a preferred embodiment of the present invention, a limiting plate 11 is movably connected inside the connecting plate 6. A movable plate 12 is fixedly connected to one side of the limiting plate 11, and a baffle 13 is fixedly connected to one side of the movable plate 12, thereby positioning the baffle 13 on one side of the connecting plate 6.

[0031] In a preferred embodiment of the present invention, the baffle 13 is movably connected to one side of the connecting plate 6 and the second keel 10, and the end of the baffle 13 away from the moving plate 12 is movably connected to the top of the second keel 10, so that the baffle 13 positions the second keel 10, thereby reducing the movement of the keel and improving stability when it is fixed.

[0032] In a preferred embodiment of the present invention, a spring 14 is fixedly connected inside the connecting plate 6, and the spring 14 is fixedly connected to one side of the limiting plate 11.

[0033] In a preferred embodiment of the present invention, two springs 14 are provided, and the two springs 14 are respectively located on both sides of the moving plate 12. The length of the limiting plate 11 is greater than the length of the moving plate 12, and the limiting plate 11 is positioned inside the connecting plate 6 to prevent the moving plate 12 and the connecting plate 6 from separating.

[0034] In a preferred embodiment of the present invention, the mounting plate 3, the positioning plate 4, the connecting plate 6, the fixing plate 9 and the connecting rod 5 are all provided with threaded holes, and bolts are provided inside the threaded holes. The bolts are fixed by rotating them into the threaded holes.

[0035] In a preferred embodiment of the present invention, two connecting rods 5 are provided. The length of the connecting rod 5 is greater than the length of the positioning plate 4, so that the connecting rod 5 can be fixed in the positioning plate 4 through different sides of the positioning plate 4. Two support rods 7 are provided on the top of each connecting rod 5. The fixing plate 9 is movably connected between the two support rods 7, so that the fixing plate 9 can be rotated to fix and disassemble the second keel 10.

[0036] The working principle of this invention is as follows: A positioning plate 4 and a mounting plate 3 are respectively provided at the top and bottom of the support plate 2. When connecting the first keel 1 and the second keel 10, the support plate 2 is moved to fit onto the first keel 1, and then moved again to position the support plate 2 at the connection point. At this time, bolts are used to fix the mounting plate 3, thereby fixing the support plate 2 onto the first keel 1. During installation, the connecting plate 6 is moved to the top of the support plate 2, so that the connecting rod 5 is located inside the positioning plate 4. Bolts are rotated into the positioning plate 4 and the connecting rod 5 for fixing, completing the installation. The second keel 10 is then fixed onto the connecting plate 6. This allows the second keel 10 to be fixed to different sides of the first keel 1 by moving the connecting plate 6 without disassembling the support plate 2, achieving convenient adjustment. The operation is simple and convenient. When fixing the second keel 10 onto the connecting plate 6, the baffle 13 is pulled outwards from the connecting plate 6, causing the moving plate 12 and the limiting plate 11 to be positioned on the connecting plate 6. Internally, the limiting plate 11 compresses the spring 14, increasing the distance between the baffle 13 and the connecting plate 6. At this time, the second keel 10 can be placed on top of the connecting plate 6. Then, the baffle 13 is released, and due to the elasticity of the spring 14, the limiting plate 11 pulls the baffle 13 to one side of the connecting plate 6, so that the baffle 13 is located on one side of the second keel 10, thereby positioning the second keel 10 on top of the connecting plate 6. This reduces the movement of the keel during fixing and provides good stability. Since the fixing plate 9 and the support rod 7 are movably connected through the connecting shaft 8, when fixing the second keel 10, the fixing plate 9 is rotated so that it is located on the outer surface of the second keel 10, with the end of the fixing plate 9 away from the support rod 7 located on one side of the connecting plate 6. The bolts are rotated into the threaded holes in the fixing plate 9 and the connecting plate 6 to fix the fixing plate 9, thereby connecting the two keels through the fixing plate 9. When disassembling, the second keel 10 can be removed by rotating the fixing plate 9. The structure is simple and easy to install and disassemble.
