Method for connecting FRP (Fiber Reinforce Plastic) profile with closed section and concrete layer
The invention discloses a connecting method for an FRP profile with a closed section and a concrete layer. The connecting method comprises the following steps that a plurality of rectangular bolt holes are formed in set positions on a top plate of the FRP profile; a T-shaped bolt is mounted in each rectangular bolt hole; a nut at the upper part is screwed into the top of a screw rod of each T-shaped bolt; epoxy resin is poured into each rectangular bolt hole; and after the epoxy resin is solidified, a concrete layer is poured on the top plate of the FRP profile, so that the FRP profile and the poured concrete layer form a whole. The structure is reasonable, construction is convenient, and the problem that installation is inconvenient when the bolt is applied to the FRP sectional material with the closed section can be effectively solved; the stress performance is good, and an FRP profile-concrete composite beam or an FRP profile-concrete composite plate can be formed; chemical bonding is avoided, and the durability is good.
本发明公开了一种具有封闭截面的FRP型材与混凝土层的连接方法，包括以下步骤：在FRP型材顶板上的设定位置开多个矩形螺栓孔；在每一个矩形螺栓孔中安装一个T型螺栓；在每个T型螺栓的螺杆的顶部旋入上部的螺母；在每个矩形螺栓孔内灌注环氧树脂；环氧树脂凝固后在FRP型材的顶板上浇筑混凝土层，使FRP型材和浇筑混凝土层形成整体。本发明结构的构造合理，施工便利，可有效解决将螺栓应用到具有封闭截面的FRP型材中安装不便的问题；受力性能好，可形成FRP型材‑混凝土组合梁或FRP型材‑混凝土组合板；避免了化学粘结，耐久性好。
