A prestressed steel carbon composite member

Abstract

The invention discloses a prestress bar-shaped steel-carbon composite component. The prestress bar-shaped steel-carbon composite component comprises a bar-shaped steel pulling plate, a bar-shaped carbon fiber plate, end joints and distribution bolts. The bar-shaped steel pulling plate is a high-strength hot-rolled sheet steel strip which is formed by overlaying an upper layer and a lower layer, and the bar-shaped carbon fiber plate is clamped between the two layers of the bar-shaped steel pulling plate. The two rows of distribution bolts are arranged. The distribution bolts are distributed at intervals in the length direction of the bar-shaped steel pulling plate, penetrate through bolt holes reserved in the two sides of the bar-shaped steel pulling plate and fasten the layered component. The length of the bar-shaped carbon fiber plate is the same as that of the bar-shaped steel pulling plate, the width of the bar-shaped carbon fiber plate is equal to the distance between the two rows of distribution bolts, and perforating on the bar-shaped carbon fiber plate is avoided. The end joints capable of guaranteeing coordination work of the bar-shaped steel pulling plate and the bar-shaped carbon fiber plate are arranged at the two ends of the composite component. The prestress bar-shaped steel-carbon composite component not only has the advantages of being easy to connect and construct and low in self weight but also has good working performance and high safety stock.

Description

technical field [0001] The invention relates to the field of prestressed components, in particular to a prestressed strip-shaped steel-carbon composite component. Background technique [0002] In recent decades, the prestressed steel structure designed in the form of large-span and large-space structure has become popular all over the world due to its novel structural form, elegant structural shape, good mechanical performance, strong spanning ability and broad application prospects. is widely used. [0003] No matter from the perspective of bionics or the best load-bearing member type, no matter from theoretical analysis or engineering practice, it has been proved that the axial tension member is the unit body that constitutes the best structural system. This kind of unit body only has strength and stiffness issues, without considering the instability issue. Early tension structures composed of tension units, such as one-way suspension cable structures, cable trusses, etc...
