FRP anti-seismic reinforcing method for masonry structure house in tropical corrosive environment
The invention provides a tropical corrosive environment masonry structure house FRP anti-seismic reinforcing method. The method comprises the following steps that S1, the inner surface of a to-be-reinforced masonry house wall is repaired and leveled; s2, drilling holes in the trimmed surface of the inner wall, and implanting FRP ribs; s3, FRP meshes are laid on the surface of the inner wall, binding and fixing are conducted on the FRP meshes and pre-implanted FRP ribs through binding belts, and then mortar is used for plastering to form a protection layer; s4, an L-shaped FRP sectional material is installed on the inner wall corner; s5, an inclined L-shaped FRP profile is installed on the top of the gable wall; and S6, the L-shaped FRP sectional material and the FRP sectional material plate are installed at the outer wall corner. The FRP material has the advantages of high specific strength, high specific stiffness, good fatigue resistance, excellent corrosion resistance in a severe service environment, easiness in cutting, convenience in construction and the like, the old masonry structure house is subjected to seismic reinforcement, the bearing capacity, the overall stiffness and the seismic resistance of the old masonry structure house can be remarkably improved, and the FRP material has the advantages of high construction speed, good durability, high durability and the like. The service life is long; and the comprehensive cost is low.
本发明提供热带腐蚀环境砌体结构房屋FRP抗震加固方法，所述方法包括以下步骤：S1、修补、整平待加固砌体房屋墙体的内表面；S2、在修整后的内墙表面钻孔植入FRP筋；S3、在内墙表面铺设FRP网片并利用扎带与预先植入的FRP筋进行绑扎固定，之后利用砂浆抹面形成保护层；S4、在内墙角安装L型FRP型材；S5、在山墙顶安装斜向L型FRP型材；S6、在外墙角安装L型FRP型材与FRP型材板。本发明利用FRP材料比强度大、比刚度大、抗疲劳性能好、在恶劣服役环境中具有优越的耐腐蚀性能以及易剪裁和施工便捷等优点，对老旧砌体结构房屋进行抗震加固，可显著提高其承载能力、整体刚度和抗震性能，且具有施工快捷、耐久性能好，使用寿命长以及综合成本低等优势。
