Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the drawings.

[0020] Such as Figure 1-4 As shown, a prestressed strip steel carbon composite component includes a strip steel pull plate 1, a strip carbon fiber plate 2, an end node 3 and a distributed bolt 4. The strip steel pull plate 1 is a high-strength hot-rolled steel plate With two layers superimposed on top of each other, a strip-shaped carbon fiber board 2 is sandwiched between the two layers of strip-shaped steel pull plates 1, and the distribution bolts 4 are in two rows, distributed at intervals along the length of the strip-shaped steel pull plate 1, and pass through The bolt holes reserved on both sides of the strip steel pull plate 1 fasten the layered member; the strip carbon fiber plate 2 has the same length as the strip steel pull plate 1, and the width is between two rows of distributed bolts 4 Avoid perforation on the strip-shaped carbon fiber board 2.

[0021] The two ends of ...

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 steel carbon composite component. Background technique [0002] In recent decades, pre-stressed steel structures designed in the form of large-span and large-space structures have become worldwide due to their novel structural forms, elegant structural shapes, good mechanical performance, strong spanning capabilities and broad application prospects. Is widely used. [0003] Whether from the perspective of bionics or the best type of load-bearing members, whether from theoretical analysis or engineering practice, it has been proved that axially tensioned members are the unit bodies that constitute the best structural system. This kind of unit has only strength and stiffness issues, without considering the instability issues. Early tension structures composed of tension elements, such as one-way suspension cables, cable trusses, etc., have developed into modern ...
