Combined glass fiber composite reinforced concrete guardrail and construction process thereof
The invention discloses a combined glass fiber composite material bar concrete guardrail and a construction technology thereof, the combined glass fiber composite material bar concrete guardrail comprises a combined reinforcement cage arranged in concrete, the slope surface of the reinforcement cage is matched with the slope surface of the concrete, and the reinforcement cage is formed by combining thermosetting glass fiber composite material bars and thermoplastic glass fiber composite material bars. The problems that the thermosetting glass fiber reinforced composite material rib cannot be subjected to secondary subsequent bending after being cured, and the mechanical property loss of the rib material bending position is large in the prefabrication bending process are solved, and the thermoplastic glass fiber composite material rib can replace the rib material of the bending section in the concrete guardrail; meanwhile, the modified polyurea coating containing carborundum is sprayed on the surface of the thermosetting glass fiber composite rib, the tensile property and elasticity modulus of the rib and the bonding strength of the rib and the concrete are remarkably improved, and the combined glass fiber composite rib concrete guardrail has the advantages of being low in cost, convenient to install, light in structure, high in strength and the like under the condition that the protection grade of the guardrail is guaranteed. The durability is good; and the later updating is convenient.
本发明公开了一种组合式玻纤复材筋混凝土护栏及其施工工艺，组合式玻纤复材筋混凝土护栏包括内置于混凝土的组合式配筋笼，所述配筋笼坡面与混凝土坡面相适配，所述配筋笼采用热固性玻纤复材筋和热塑性玻纤复材筋组合而成。本发明解决了热固性玻纤增强复材筋固化后无法二次进行后续弯折，且预制弯折时对其筋材弯折处的力学性能损失较大的问题，采用热塑性玻纤复材筋可替代混凝土护栏中弯曲段的筋材，同时通过在热固性玻纤复材筋表面喷涂含有金刚砂的改性聚脲涂层，显著增强筋材的抗拉性能和弹性模量及与混凝土的粘接强度，在保证护栏防护等级情况下，组合式玻纤复材筋混凝土护栏具有成本低，方便安装，结构轻量化，耐久性好及后期更新便捷等优点。
