The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be rust-free, galvanized or painted, and maintained regularly.

The first spring 49 is sleeved on the outer periphery of the mounting rod 46 and its two ends are respectively fixedly connected to one side of the first slider 48 and the inner wall of one side of the first slide groove 47. The pull block 410 is fixedly connected to the outer end of the mounting rod 46. Pulling the pull block 410 outward can drive the mounting rod 46 to move outward and squeeze the first spring 49 through the first slider 48. Release the pull block 410, the first spring 49 rebounds and can drive the mounting rod 46 to move inward through the first slider 48.

[0028] In some examples, the connecting component 6 includes a connecting hole 61, a mounting plate 62 and a connecting rod 63. The connecting hole 61 is opened on the surface of the connecting block 5 on one side of the upper cover 1 and the lower cover 2. The mounting plate 62 is movably connected to the surface of the connecting block 5 on the other side of the upper cover 1 and the lower cover 2. The connecting rod 63 is fixedly connected to the inner side of one end of the mounting plate 62 and is adapted to the size of the connecting hole 61. The connection of the two groups of connecting blocks 5 can be completed by inserting the connecting rod 63 into the connecting hole 61, thereby connecting multiple groups of upper covers 1 and lower covers 2, thereby increasing the protection strength of the device.

[0029] In some examples, the connecting component 6 also includes a second through hole 64, a second slide groove 65, a pull rod 66, a second slider 67 and a second spring 68. The second through hole 64 is opened on the surface of the connecting block 5 on the other side of the upper cover 1 and the lower cover 2, the second slide groove 65 is opened inside the connecting block 5 on the other side of the upper cover 1 and the lower cover 2 and is connected with the second through hole 64, the pull rod 66 is movably connected to the second through hole 64 and extends to the inside of the second slide groove 65, the end of the mounting plate 62 away from the connecting rod 63 is rotatably connected to the outer end of the pull rod 66, the second slider 67 is fixedly connected to the inner end of the pull rod 66 and slidably connected to the second slide groove 65, the second spring 68 is fixedly installed inside the second slide groove 65 and its two ends are respectively fixedly connected to one side of the second slider 67 and the inner wall of one side of the second slide groove 65, pulling the pull rod 66 outward can drive the second slider 67 to slide outward along the second slide groove 65 and stretch the second spring 68, and releasing the pull rod 66, the second spring 68 rebounds and drives the pull rod 66 to move inward through the second slider 67.

[0030] In a specific application scenario, firstly, a set of upper cover 1 and lower cover 2 are placed on the top and bottom of the steel structure respectively, and then the upper cover 1 and the lower cover 2 are pushed downward and upward respectively, and the mounting block 41 and the mounting seat 42 move synchronously with the upper cover 1 and the lower cover 2. When the mounting block 41 is inserted into the mounting groove 43 of the mounting seat 42 and contacts the mounting rod 46, since the cross section of the mounting rod 46 is a right-angle trapezoid, the mounting rod 46 will be pushed outward by the mounting block 41 and squeeze the first spring 49 through the first slider 48. When the mounting rod 46 continues to move, the mounting rod 46 will move downward. When the mounting hole 44 and the mounting rod 46 are moved downward to the same axis, the first spring 49 rebounds and drives the mounting rod 46 to move inward through the first slider 48. When the mounting rod 46 is inserted into the mounting hole 44, the mounting block 41 can be fixed in the mounting groove 43, thereby completing the installation of the upper cover 1 and the lower cover 2. At this time, the upper cover 1 and the lower cover 2 can protect the steel structure node. After the four sets of upper covers 1 and lower covers 2 are installed in this way, the pull rod 66 is pulled outward to drive the mounting plate 62 and the second slider 67 to move outward synchronously. The second spring 68 is moved and stretched. When the connecting rod 63 moves synchronously with the mounting plate 62 to move away from the surface of the connecting block 5, the mounting plate 62 is rotated to drive the connecting rod 63 to rotate synchronously. When the connecting rod 63 rotates to be on the same axis as the connecting hole 61, the pull rod 66 is released, and the second spring 68 rebounds and drives the pull rod 66 to move inward through the second slider 67. When the mounting plate 62 drives the connecting rod 63 to move inward along with the pull rod 66 to be inserted into the connecting hole 61, the connection of the two sets of connecting blocks 5 is completed, thereby making the four The upper cover 1 and the lower cover 2 are formed as a whole, which effectively increases the protection strength. When the device needs to be disassembled, the pull rod 66 is pulled outward again so that it drives the connecting rod 63 to move out of the connecting hole 61 through the mounting plate 62, and then the mounting plate 62 is rotated to drive the connecting rod 63 to move away from the axis of the connecting hole 61. At this time, the disassembly of multiple groups of upper covers 1 and lower covers 2 can be completed, and then the pull block 410 is pulled outward again to drive the mounting rod 46 to move outward. When the mounting rod 46 is moved out of the mounting hole 44, the upper cover 1 and the lower cover 2 can be disassembled.

[0031] By adopting the above technical solution: not only can the split design make the installation and disassembly of the device simpler and faster, effectively improving work efficiency, but also multiple groups of devices can be connected together to effectively increase the structural strength of the device, thereby increasing the protection strength of the steel structure nodes.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the scope of protection of the present invention.
