Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a steel structure pre-tensioning component with bidirectional adjustment. Background Art

[0002] Steel structure refers to a building structure or other engineering structure constructed using steel (usually carbon steel or alloy steel). Steel structure has the characteristics of high strength, high rigidity and corrosion resistance, so it is widely used in construction and bridge engineering. Prestressed components are a type of component used to enhance the bearing capacity of concrete structures, and are commonly used in bridges, buildings and other projects. Steel structure prestressed components refer to a type of component used in construction projects, which are usually used to provide strength and stability to the structure. These components are usually pre-stretched before construction to increase their bearing capacity. Prestressed components are usually made of high-strength steel, which can provide greater tensile resistance when subjected to stress.

[0003] After searching, the Chinese patent with authorization announcement number CN218562357U discloses a steel structure pre-tensioning component with bidirectional adjustment, including an upper plate, a longitudinal slider A, a longitudinal slider B, a transverse slider B, a transverse slider A, a transverse connecting plate and a longitudinal connecting plate. In the utility model, by setting a turntable, the turntable is rotated, and the stretching screw and the tension frame are matched, so that the stretching upper clamp and the stretching lower clamp perform bidirectional pre-tensioning on the steel structure, which is simple to operate and convenient for the next step of use, thereby improving the practicality of the pre-tensioning component; by setting the transverse connecting plate, the transverse first motor drives the transverse screw to cooperate with the transverse connecting plate to move, so that the transverse slider B and the transverse slider A on the upper end of the transverse connecting plate can be adjusted laterally, and by setting the longitudinal connecting plate, the longitudinal first motor drives the longitudinal screw to cooperate with the longitudinal screw to move, so that the longitudinal slider A and the longitudinal slider B on the upper end of the longitudinal screw can be adjusted longitudinally, which is convenient for movement when installing different steel structures, thereby making the pre-tensioning component more widely used.

[0004] However, the above technology still has shortcomings. When used, the existing pre-tensioning components can usually only pre-tension steel structures of a single size, and have poor versatility. In addition, a single screw is used to limit the clamping assembly, which has poor stability. For this reason, we propose a steel structure pre-tensioning component with bidirectional adjustment to solve this problem. Utility Model Content
