One-way slidable shearing force connecting piece based on triangular limiting structure and construction method of one-way slidable shearing force connecting piece
The invention relates to a one-way slidable shear connector based on a triangular limiting structure, the one-way slidable shear connector is used for connecting a steel beam and a concrete plate in a composite beam structure, the one-way slidable shear connector comprises an inclined steel plate and a vertical steel plate, and the inclined steel plate and the vertical steel plate form a triangular shear key; the inclined steel plate is a bevel edge of the triangular shear key and is used for assisting the steel beam to slide outwards, and the vertical steel plate is a vertical edge of the triangular shear key and is used for ensuring that the steel beam and the concrete slab are fixed inwards. The shearing force connecting piece is simple in structure, low in cost and convenient to construct, one-way sliding of a hogging moment area is achieved through the sliding effect of the inclined steel plate and the limiting effect of the vertical steel plate, constraint between the steel beam and the concrete plate can be released, tensile stress generated by cooperative deformation of the concrete plate and the steel beam is effectively avoided, and the service life of the concrete plate is prolonged. The durability of the structure is improved, meanwhile, waste of prestress in the concrete slab is effectively avoided, and the work amount of prestress construction is reduced.
本发明涉及一种基于三角限位结构的单向可滑移剪力连接件，用于组合梁结构中钢梁与混凝土板的连接，所述单向可滑移剪力连接件包括倾斜钢板与竖直钢板，所述倾斜钢板与竖直钢板组成三角形剪力键；所述倾斜钢板为三角形剪力键的斜边，用于辅助所述钢梁向外滑移，所述竖直钢板为三角形剪力键的竖直边，用于确保所述钢梁与混凝土板向内固定。该剪力连接件结构简单、成本低廉、施工方便，利用倾斜钢板的滑移作用与竖直钢板的限位作用，实现了负弯矩区的单向滑移，可以释放钢梁与混凝土板之间的约束，有效避免了因混凝土板与钢梁协同变形而产生的拉应力，提升了结构的耐久性，同时有效避免了混凝土板中预应力的浪费，减少了预应力施工的工程量。
