Key tooth bolt connecting piece suitable for full-assembly type composite beam and rapid construction method
The invention discloses a key tooth bolt connecting piece suitable for a full assembly type composite beam and a rapid construction method of the key tooth bolt connecting piece. The connecting piece comprises steel key teeth, concrete key teeth and high-strength bolts pre-buried in the concrete key teeth, and the concave-convex concrete key teeth are formed at the bottom of a prefabricated concrete slab; the high-strength bolts are pre-embedded in the convex concrete key teeth, a plurality of steel key teeth are welded on the steel beam flange, the steel key teeth are just matched in the concave concrete key teeth in sequence in a one-to-one correspondence manner along the longitudinal direction of the beam to form a combined key tooth shear connector, a plurality of connecting holes are correspondingly formed in the steel beam flange, and the pre-embedded high-strength bolts are matched in the connecting holes in a one-to-one correspondence manner. The stress mechanism of the connecting piece is clear and definite, the concrete key teeth can improve the shear resistance of the composite beam, the high-strength bolts provide pulling resistance, the connecting piece is suitable for various composite beam structure forms, the structure is simple, rapid mounting and dismounting between the prefabricated concrete plate and the steel beam can be achieved, the construction efficiency is improved, and green development of industrialization of the composite beam is promoted.
本发明公开了一种适用于全装配式组合梁的键齿螺栓连接件及其快速施工方法，连接件包括相互配合的钢键齿、混凝土键齿以及预埋于混凝土键齿内的高强螺栓，预制混凝土板底部形成凹凸的混凝土键齿，高强螺栓预埋于凸形的混凝土键齿处，钢梁翼缘上焊接数个钢键齿，其恰好一一对应沿梁纵向依次配合于凹形的混凝土键齿内形成组合键齿抗剪连接件，钢梁翼缘上对应设置有数个连接孔，预埋的高强螺栓一一对应配合于连接孔内。本发明连接件受力机理清晰明确，混凝土键齿能够提高组合梁的抗剪性能，高强螺栓提供抗拔力，适用于多种组合梁结构形式，并且构造简单，可以实现预制混凝土板与钢梁之间的快速安装与拆卸，提高施工工效，推进组合梁工业化绿色发展。
