Carbon fiber cloth bidirectional prestress applying device for FRP reinforcement
The invention discloses a carbon fiber cloth bidirectional prestress applying device for FRP (fiber reinforced plastic) reinforcement, which comprises a left side tensioning and anchoring mechanism, a right side tensioning and anchoring mechanism and a bidirectional jacking device arranged between the left side tensioning and anchoring mechanism and the right side tensioning and anchoring mechanism, the two ends of the carbon fiber cloth are clamped and fixed to the left side tensioning and anchoring mechanism and the right side tensioning and anchoring mechanism correspondingly, and the left side tensioning and anchoring mechanism and the right side tensioning and anchoring mechanism move in the direction away from the two-way supporting and jacking device under the opening effect of the two-way supporting and jacking device. The left side tensioning and anchoring mechanism and the right side tensioning and anchoring mechanism stretch and draw the carbon fiber cloth at the same time to achieve the purpose of bidirectionally applying prestress. According to the device, the carbon fiber cloth can be bidirectionally tensioned, the problem that the prestress on one side is too large and the prestress on the other side is insufficient due to the fact that the stress of the carbon fiber cloth is concentrated on one side is solved, and the prestress can be uniformly distributed on the large-span carbon fiber cloth in a bidirectionally tensioned prestress applying mode.
本发明公开了FRP加固用的碳纤维布双向预应力施加装置，包括左侧张拉锚固机构、右侧张拉锚固机构和双向撑顶器，双向撑顶器设置于左侧张拉锚固机构和右侧张拉锚固机构之间，碳纤维布的两端分别夹持固定于左侧张拉锚固机构和右侧张拉锚固机构上，左侧张拉锚固机构和右侧张拉锚固机构在双向撑顶器的撑开作用下分别向远离双向撑顶器的方向移动，左侧张拉锚固机构和右侧张拉锚固机构同时对碳纤维布进行张拉达到双向施加预应力的目的。该装置能够对碳纤维布进行双向张拉，防止碳纤维布应力集中一侧而导致一侧预应力过大、另一侧预应力不足的问题发生，双向张拉施加预应力的方式可使预应力能够在大跨度得碳纤维布上均匀分布。
