Self-pre-tightening multi-layer CFRP one-way plate cable tensioning anchorage device and construction method thereof
The invention discloses a self-pretightening multilayer CFRP (carbon fiber reinforced plastic) one-way plate cable tension anchorage device and a construction method thereof, hole groups on an anchor block adopt a symmetrical 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 radial direction facing the plane center of the anchor block, so that the self-pretightening multilayer CFRP one-way plate cable tension anchorage device is formed, and the self-pretightening multilayer CFRP one-way plate cable tension anchorage device is formed. Therefore, the CFRP one-way plate is clamped and anchored through friction. The multiple extrusion hole groups are annularly and symmetrically distributed, 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-layer CFRP one-way plate cable tensioning anchorage device, large-tonnage anchoring of the multiple CFRP one-way plates is achieved, the anchoring tonnage is increased, meanwhile, the size and the self weight of the anchor block are reduced, and therefore the adaptability of the anchorage device is improved. 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层CFRP单向板索张拉锚具及其施工方法，其锚块上的孔群采用对称自锚设计，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锚块的平面中心的径向方向上的挤压力，从而对CFRP单向板夹持并利用摩擦进行锚固。多道挤压孔群环向对称布设，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。本发明的自预紧多层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，从而增加锚具的适应性。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。
