Concrete structure block with buffer connecting structure
The invention relates to the field of bridge and house concrete building construction, and discloses a concrete structure block with a buffer connecting structure, which is characterized in that a steel strand or a steel bar is protected to bear the external load exceeding the conventional working condition as design details, the core is that a partial V-shaped buffer cavity for eliminating shearstress concentration at the intersection of two structural parts and a stranded reinforcing pin rod capable of applying prestress similar to a steel strand are designed. Except for improving stress distribution, the V-shaped buffer cavity has local guiding and positioning effects, and the modular construction is easy; and meanwhile, a space with a reinforced local structure is provided to meet thestrength requirement of special working conditions, and the connected components are allowed to be relatively dislocated under strong shock impact so as to play a role in shock absorption and isolation. Under the same working condition, the hinge support design of the reinforcing pin rod enables the size of the V-shaped buffer cavity to be reduced, the construction is convenient, and meanwhile, the function of preventing the upper structure of a connected bridge from overturning under strong earthquake and heavy load is achieved.
本发明涉及桥梁和房屋混凝土建筑施工领域，本发明公开了具有缓冲连接结构的混凝土结构块，其特征在于保护钢绞线或钢筋使之能够承受超过常规工况外载荷的设计细节；其核心是为消除两结构件相交处剪应力集中局部V型缓冲腔和可以施加预应力类似钢绞线的绞支加强销杆设计。除了改善应力分布，V型缓冲腔有局部导向和定位作用，易于模块化建设；同时提供局部结构加强的空间来满足特殊工况强度要求，并允许所连接构件在强震冲击下相对错动以起到减隔震的功能。在同等工况下，所述加强销杆的绞支设计使得V型缓冲腔体积缩小，便于施工，同时具有防止所连接桥梁上部结构在强震和重载下倾覆的功能。
