Description

Technical Field

[0001] The utility model relates to the field of camera technology, and in particular mainly to a steel structure with a reinforced framework. Background Art

[0002] Steel structure building is a new type of building system. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, which has higher strength and better earthquake resistance.

[0003] Publication number CN219794185U discloses a building steel structure with a reinforced frame. In the device, the steel structure cross beam and the steel structure vertical beam are not only connected by a connecting plate, a first screw and a second screw, but the connection is also reinforced for a second time by a first movable plate, a second movable plate and a vertical plate. The cross plate and the inner side of the steel structure vertical beam fit each other, so that the connection is not only connected by the connecting plate, the first screw and the second screw, and the stability of the device is higher.

[0004] However, the surface of the steel structure beam of the steel structure is provided with a first mounting hole. The steel structure beam is mainly subjected to tension and pressure. The opening of the hole will destroy the original structural form and cause destructive concentration of the cross section of the steel structure beam, resulting in local stress concentration, thereby reducing the strength and bearing capacity of the structure. The presence of the hole will cause stress concentration in the beam when subjected to force, which is prone to plastic deformation and fatigue failure. Utility Model Content

[0031] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0032] Reference Figures 1 to 6 The steel structure with a reinforced frame in this embodiment includes a steel structure cross beam 1 and a steel structure vertical beam 2. A reinforced connection mechanism 3 is provided on the inner wall and surface of the steel structure cross beam 1. The reinforced connection mechanism 3 includes: a sliding connection member 31, a bolt head 32, a rotating cylindrical block 33, a threaded rod 34, and a fixing plate 35.

[0033] A sliding connector 31 is slidably connected to the inner wall of the side of the steel structure crossbeam 1, and a rotating cylindrical block 33 is rotatably connected to the inner wall of the sliding connector 31. A bolt head 32 is fixedly connected to the surface of the rotating cylindrical block 33 on the side close to the steel structure vertical beam 2, and a threaded rod 34 is fixedly connected to the surface of the rotating cylindrical block 33 away from the bolt head 32. A fixing plate 35 is fixedly connected to the inner wall of the side of the steel structure crossbeam 1. By rotating the bolt head 32, the bolt head 32 drives the rotating cylindrical block 33, and the rotating cylindrical block 33 drives the threaded rod 34 to rotate. The threaded rod 34 rotates left and right on the inner wall of the fixing plate 35, so that the sliding connector 31 moves left and right, which adjusts the lateral distance of the steel structure crossbeam 1, avoids the difficulty of fixing the steel structure crossbeam 1 to the steel structure vertical beam 2 due to manufacturing errors and installation errors, and plays a role in facilitating installation. At the same time, the steel structure beam 1 has a large contact area with the sliding connector 31, and the added fixing plate 35 improves the structural strength of the steel structure beam 1, and there is no need to open a mounting hole on the original surface of the steel structure beam 1, so as to avoid destructive concentration of the cross section of the steel structure beam 1 and cause local stress concentration, thereby improving the strength and bearing capacity of the structure. A hexagonal prism groove is opened on the inner wall of the bolt head 32, which is convenient for using an electric screwdriver to rotate the bolt head 32. The inner wall of the fixing plate 35 is penetrated by the threaded rod 34, and the inner wall of the fixing plate 35 is threadedly connected to the threaded rod 34, so that the threaded rod 34 can rotate and move left and right relative to the fixing plate 35. The sliding connector 31 is T-shaped, which is convenient for the sliding connector 31 to be inserted into the steel structure beam 1, so that the steel structure beam 1 can be connected without drilling a hole.

[0034] The inner wall of the steel structure vertical beam 2 and the surface of the sliding connection member 31 are provided with a pre-fixing mechanism 4, which includes: a fixing nut 41, a fixing nut 41 is fixedly connected to the inner wall of the steel structure vertical beam 2, one end of a spring 42 is fixedly connected to the surface of the sliding connection member 31 away from the steel structure vertical beam 2, and the other end of the spring 42 is fixedly connected to a connecting plate 43, a surface of a pre-fixing bolt 44 is rotatably connected to the inner wall of the connecting plate 43, a guide column 45 is fixedly connected to the surface of the pre-fixing bolt 44, and a ball 46 is rotatably connected to the surface of the guide column 45 away from the pre-fixing bolt 44. The structural cross beam 1 is placed between two steel structure vertical beams 2, and the connecting plate 43 is slightly pulled to move away from the steel structure vertical beam 2, and then released when the ball 46 contacts the surface of the steel structure vertical beam 2, and then the steel structure cross beam 1 is moved so that the ball 46 is aligned with the mounting hole on the surface of the steel structure vertical beam 2, and then under the action of the spring 42, the spring 42 drives the connecting plate 43 and the pre-fixing bolt 44 to move toward the steel structure vertical beam 2, so that the guide column 45 enters the inner wall of the fixing nut 41, which plays a guiding role, so that the steel structure cross beam 1 does not need to be manually supported, and plays a pre-fixing role. Then the pre-fixing bolt 44 is rotated to tighten with the fixing nut 41 to complete the installation, and the surface of the connecting plate 43 is slidably connected with the surface of the sliding connector 31, so that the connecting plate 43 can stably slide left and right on the surface of the sliding connector 31.

[0035] In summary: by rotating the bolt head 32, the bolt head 32 drives the rotating cylindrical block 33, and the rotating cylindrical block 33 drives the threaded rod 34 to rotate. The threaded rod 34 rotates left and right on the inner wall of the fixed plate 35, so that the sliding connection 31 moves left and right, which adjusts the lateral distance of the steel structure beam 1, avoids the difficulty of fixing the steel structure beam 1 with the steel structure vertical beam 2 due to manufacturing errors and installation errors, and facilitates installation.

[0036] At the same time, the contact area between the steel structure beam 1 and the sliding connection 31 is large, and the added fixing plate 35 improves the structural strength of the steel structure beam 1. There is no need to open installation holes on the original surface of the steel structure beam 1, which avoids destructive concentration of the cross section of the steel structure beam 1 and causes local stress concentration, thereby improving the strength and bearing capacity of the structure.

[0037] Place the steel structure cross beam 1 between two steel structure vertical beams 2, slightly pull the connecting plate 43 to move away from the steel structure vertical beam 2, release it when the ball 46 contacts the surface of the steel structure vertical beam 2, then move the steel structure cross beam 1 so that the ball 46 is aligned with the mounting hole on the surface of the steel structure vertical beam 2, and then under the action of the spring 42, the spring 42 drives the connecting plate 43 and the pre-fixing bolt 44 to move toward the steel structure vertical beam 2, so that the guide column 45 enters the inner wall of the fixing nut 41, playing a guiding role, so that the steel structure cross beam 1 does not need to be manually supported, and plays a pre-fixing role. Then turn the pre-fixing bolt 44 and the fixing nut 41 to tighten, and complete the installation.
