Technical Field

[0001] The present invention relates to the technical field of steel components, in particular to a design structure of a large-span anti-deformation steel component. Background Art

[0002] In order to ensure the structural strength and wind impact resistance of existing factories and other buildings, large-span steel structures are often designed with arched structures in combination with curved roof panels. Although this steel structure can ensure basic use, in adverse external environments such as high wind speeds, the large windward surface at the top will significantly accelerate structural fatigue, reduce service life, and increase the risk of use. Arched structures and common straight steel structures also have the problem of sinking and deformation in the middle, which also affects the structural strength, service life and safety of the steel structure. In addition, during the assembly and construction of common large-span steel structures, construction workers are required to carry out high-altitude assembly operations for a long time, which reduces the efficiency and safety of steel structure assembly and construction. Large-span steel components are usually composed of multiple small components welded together. Due to long-term vibration, there is a risk of loose welds, posing a safety hazard. Summary of the Invention

[0003] The purpose of the present invention is to provide a large-span anti-deformation steel member design structure in order to solve the problem that welding between steel members may have the risk of loosening welds due to long-term vibration, which poses a safety hazard.

[0036] In the description of the embodiments of the present invention, it should be noted that the terms "upper" and "inner" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are orientations or positional relationships in which the inventive product is usually placed when in use. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] See also Figure 1-3 The present invention provides a long-span anti-deformation steel member design structure, which includes:

[0039] A first steel member 1 having a mounting hole 2 provided thereon;

[0040] a second steel member 3 , on which a clamping assembly is provided, and through which the second steel member 3 is connected to the mounting hole 2 ;

[0041] The maximum outer diameter of the clamping assembly is larger than the diameter of the mounting hole 2, and the clamping assembly is elastic, so that the surface of the clamping assembly abuts against the wall of the mounting hole 2. This allows the clamping assembly, the first steel member, and the second steel member to be more tightly connected and prevent them from falling off.

[0042] The second steel member 3 is provided with a first mounting groove 4, and the clamping assembly is located in the first mounting groove 4. The first mounting groove is arranged along the circumference of the second steel member, and a step structure is formed between the first mounting groove and the second steel member, so that the second steel member is not easily separated from the clamping assembly.

[0043] The clamping assembly includes two clamping units 5, each comprising an elastic element 51, a protective shell 52, and a base 53. The protective shell 52 is sleeved onto the elastic element 51, and the base 53 is embedded in the end of the elastic element 51 away from the protective shell 52. The base 53 is elastic. The elastic element is made of a highly elastic material such as rubber to ensure elastic deformation and elastic recovery after vibration. The protective shell is made of a rigid material such as metal or hard plastic, requiring high rigidity and resistance to deformation.

[0044] The elastic element 51 is provided with a second mounting groove 6, and the base 53 is mounted in the second mounting groove. The base is fixedly connected to the elastic element to facilitate fixed mounting of the base.

[0045] The elastic element 51 is provided with a positioning groove 7, and the protective shell 52 is provided with a positioning post 8, which is inserted into the positioning groove 7. The positioning post 8 is provided with at least one rib, and the groove wall of the positioning groove 7 is provided with a retaining groove that matches the rib. This prevents the protective shell and the elastic element from rotating.

[0046] The elastic element 51 is provided with at least two screw holes 9, and screws are provided in the screw holes 9. The elastic element can be connected to the first steel member by screws, which is convenient for installation and removal and is also more firmly fixed.

[0047] The elastic element 51 is frustoconical in shape, and the protective shell 52 matches the shape of the elastic element 51. The base is also frustoconical. The protective shell compresses the elastic element downward, preventing excessive inward compression. The base, in combination with the protective shell, creates a shear force, causing the elastic element to deform in shear, absorbing vibration energy. The base compresses the elastic element upward, creating a shear force with the protective shell, causing the elastic element to deform in shear, absorbing vibration energy. Throughout the vibration process, the elastic element experiences significant deformation, representing the primary area for absorbing vibration energy.

[0048] The base 53 is a disc spring. The disc spring has rigidity and can be elastically deformed to meet the requirements of use. In addition to the disc spring, other materials that are both rigid and can be appropriately deformed can also be selected to make the rigid base.

[0049] Working principle: When in use, first assemble the elastic element, protective shell and base to form a snap-on unit, then use screws to connect the snap-on unit to the first steel member, and then insert the second steel member between the two snap-on units to form an interference fit to complete the installation between the steel members. Therefore, the present invention provides a snap-on assembly, which simplifies the assembly between the steel members and improves the installation efficiency. At the same time, the snap-on assembly is elastic, which can avoid the defect of loose solder joints, effectively ensure the trouble-free use time of the steel member, and increase the service life of the steel member. The main body of the snap-on assembly is an elastic element, which can absorb external vibrations in multiple directions and solve the problem of vibration prevention of the steel member. The protective shell and the base are respectively installed at the upper and lower ends of the elastic element. The protective shell and the base are rigid, so that the whole has a certain rigidity to support the steel member. The protective shell and the base are fixedly connected to the elastic element so that the two do not separate during vibration, and the height of the protective shell is lower than that of the elastic element, so that the elastic element has a certain deformation space, which absorbs vibration through elastic deformation, and can serve the purpose of buffering, thereby improving the anti-deformation performance.

[0050] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
