Fiber reinforced composite material rib combined extrusion anchorage device and extrusion method thereof
The invention discloses a fiber reinforced composite material rib combined type extrusion anchorage device and an extrusion method thereof, and relates to an extrusion anchorage device and an extrusion method, the extrusion anchorage device comprises a plurality of extrusion sleeves which are connected in series and anchored on a single fiber reinforced composite material rib, and the extrusion sleeves are tightly attached together. An inner hole of the extrusion sleeve is provided with internal threads or coated with carborundum and an adhesive; the outer diameter of the extrusion sleeve closer to the free end is larger before extrusion, and the outer diameter of the extrusion sleeve closer to the load-bearing end is smaller before extrusion. The extrusion method comprises the following steps: firstly installing the extrusion device, then enabling a single fiber reinforced composite material rib to penetrate through the central hole of the extrusion die, coating a lubricant on the plurality of extrusion sleeves, then connecting the plurality of extrusion sleeves in series at the end part of the fiber reinforced composite material rib, finally enabling the fiber reinforced composite material rib to penetrate into the top pressure head, and operating the jack to extrude and anchor the plurality of extrusion sleeves which are connected in series. Bending deformation of the extrusion sleeve after extrusion can be reduced, damage to the rib material is reduced, a long extrusion anchoring section is achieved, anchoring is reliable, and the anchoring and using requirements of the fiber material rib can be met.
一种纤维增强复合材料筋组合式挤压锚具及其挤压方法，涉及一种挤压锚具及挤压方法，挤压锚具包括多个串联锚固在单根纤维增强复合材料筋上的挤压套，各挤压套紧密贴合在一起。挤压套内孔设有内螺纹或涂抹金刚砂、胶粘剂；越靠近自由端的挤压套挤压前外径越大，越靠近受荷端的挤压套挤压前外径越小。挤压方法是先安装挤压装置，再将单根纤维增强复合材料筋穿过挤压模的中心孔，将多个挤压套涂抹润滑剂后串联在纤维增强复合材料筋端部，最后将该纤维增强复合材料筋穿入顶压头，操作千斤顶对多个串联的挤压套实施挤压锚固。本发明可减少挤压套受挤压后的弯曲变形，减少筋材损伤，实现较长的挤压锚固段，锚固可靠，可满足纤维材料筋的锚固及使用要求。
