Self-pre-tightening multi-piece CFRP one-way plate cable tensioning anchorage device and construction method thereof
The invention discloses a self-pre-tightening multi-piece CFRP one-way plate cable tensioning anchorage device and a construction method thereof, hole groups on an anchor block of the self-pre-tightening multi-piece CFRP one-way plate cable tensioning anchorage device adopt a matrix type self-anchoring design, a single extrusion insertion plate is arranged in each hole channel, and the extrusion insertion plates and the side walls of the hole channels form extrusion force in the thickness direction of CFRP one-way plates, so that the self-pre-tightening multi-piece CFRP one-way plate cable tensioning anchorage device is formed. Therefore, the CFRP one-way plate is clamped and anchored through friction, and stress distribution in the anchor block is optimized. When the anchorage device is used, the pushing and pressing piece presses and abuts against the extrusion inserting plate, the CFRP one-way plate is extruded and pre-tightened, a preset friction force is formed, and the initial self-locking capacity of the anchorage device is improved. According to the self-pre-tightening multi-piece CFRP one-way plate cable tensioning anchorage device, large-tonnage anchoring of the multiple pieces of CFRP one-way plates is achieved, the anchoring tonnage is increased, and meanwhile the size and the self weight of the anchor block are reduced. The problems that in building construction, most of existing CFRP anchoring systems are single-layer (single-block) anchoring, and large-tonnage anchoring is difficult to achieve are solved.
本发明公开了一种自预紧多片CFRP单向板索张拉锚具及其施工方法，其锚块上的孔群采用矩阵式自锚设计，每个孔道内设置单一挤压插板，挤压插板与孔道的侧壁形成在朝向CFRP单向板的厚度方向上的挤压力，从而对CFRP单向板夹持并利用摩擦进行锚固，优化锚块内的应力分布。在使用时，通过顶压件压抵挤压插板实现对CFRP单向板挤压预紧形成一个预设的摩擦力，提高锚具的初始自锁能力。本发明的自预紧多片CFRP单向板索张拉锚具，实现了多片CFRP单向板的大吨位锚固，在增加锚固吨位的同时，缩小了锚块的体积和自重。本发明解决了在建筑施工中，现有的CFRP锚固系统多为单层(单块)锚固，难以实现大吨位锚固的问题。
