Node connecting piece for precast one-way slab notch reinforcement connection, and assembling method thereof
The invention provides a node connecting piece for precast one-way slab notch reinforcement connection. The node connecting piece comprises an L-shaped steel plate, a first fixed part and a second fixed part, wherein the L-shaped steel plate comprises a first steel plate and a second steel plate perpendicular to the first steel plate; the first steel plate of the L-shaped steel plate is fixed to the bottom part of one side of a precast one-way slab notch through the first fixed part, so that the strength of the precast one-way slab notch is improved; and second steel plates of two L-shaped steel plates fixed to the bottom parts of one sides of two adjacent precast one-way slab notches are mutually fixed through the second fixed part, so that the lateral stability of the connecting part ofthe two adjacent precast one-way slab notches is improved. On the basis of the node connecting piece provided by the invention, the reinforcement and the lateral stability of the precast one-way slabnotch (a hole opening part) can be improved, so that the hole opening position of a precast one-way slab is not restricted in the center, the occurrence of the phenomenon of local stress concentrationdue to hole opening in the center is avoided, and the stress performance and the structure stability of the precast one-way slab are improved.
本发明提供了一种用于预制单向板凹口补强连接的节点连接件，所述节点连接件包括：L型钢板、第一固定部件及第二固定部件；L型钢板包括第一钢板和与第一钢板垂直的第二钢板，第一固定部件将L型钢板的第一钢板固定于预制单向板凹口一侧的底部，以增强预制单向板凹口处的强度；第二固定部件将固定于相邻两块预制单向板凹口一侧的底部的两个L型钢板的第二钢板相互固定，以增强相邻两块预制单向板连接处的侧向稳定性。基于本发明的节点连接件能够实现预制单向板凹口处(开洞处)补强和侧向稳定性增加，因此，预制单向板的开洞位置不再局限于居中开洞，避免因居中开洞出现局部应力集中现象，改善了预制单向板的受力性能和结构稳定性。
