Steel structure splicing joint
The invention relates to a steel structure splicing joint which comprises a first steel beam, a second steel beam, a plurality of high-strength bolts and a plurality of base plates. A first end plate is arranged on the first steel beam, a plurality of first connecting holes are formed in the first end plate, a second end plate is arranged on the second steel beam, a plurality of second connecting holes are formed in the second end plate, a plurality of third connecting holes are formed in the base plate, and the high-strength bolts sequentially penetrate through the first connecting holes, the second connecting holes and the third connecting holes. The nominal diameter d1 of the first connecting hole and the nominal diameter d2 of the second connecting hole meet the following relation: 1.2 d1 < = d2 < = 2d1, and the nominal diameter d1 of the first connecting hole is equal to the nominal diameter d3 of the third connecting hole. The problem that stress distribution on the end plates is not uniform due to forced displacement of the connecting holes in the mounting process can be avoided, the problem that bolts are difficult to mount in a hole alignment mode due to position deviation of the connecting holes in the multiple dismounting and mounting processes is solved, and the reusability of the first steel beam and the second steel beam is improved.
本发明涉及一种钢结构拼接节点，包括第一钢梁、第二钢梁、多个高强度螺栓和多个垫板；第一钢梁上设有第一端板，第一端板上设有多个第一连接孔，第二钢梁上设有第二端板，第二端板上设有多个第二连接孔，垫板上设有多个第三连接孔，高强度螺栓依次穿过第一连接孔、第二连接孔和第三连接孔；第一连接孔的公称直径d1与第二连接孔的公称直径d2满足如下关系：1.2d1≤d2≤2d1，第一连接孔的公称直径d1与第三连接孔的公称直径d3相等。本发明能避免连接孔在安装过程中的强制位移，进而造成端板上应力分布不均，避免在多次拆装过程中连接孔位置偏移导致的螺栓对孔安装困难问题，提高第一钢梁、第二钢梁的复用性能。
