Description

一种卡插式全螺栓连接钢结构梁柱节点A snap-in full-bolt connection of beam-column joints in steel structures

技术领域technical field

本实用新型涉及一种钢结构梁柱节点,具体涉及一种卡插式全螺栓连接钢结构梁柱节点。The utility model relates to a beam-column joint of a steel structure, in particular to a beam-column joint of a snap-in full bolt connection of a steel structure.

背景技术Background technique

在冷弯方钢管柱与H型截面梁的连接中,连接柱与梁的现行方法主要以现场焊接为主,但焊缝质量的可靠性受焊工的技术熟练程度和焊接环境的影响,当焊工经验的不足可能就会导致焊接的质量不可靠,而且施焊时所处的焊接环境也会对焊缝质量造成一定的影响,此外现场焊接的工艺较复杂,所需时间较长,制约了整个结构的施工速度。In the connection of cold-formed square steel pipe columns and H-section beams, the current method of connecting columns and beams is mainly on-site welding, but the reliability of weld quality is affected by the technical proficiency of the welder and the welding environment. The lack of experience may lead to unreliable welding quality, and the welding environment during welding will also have a certain impact on the quality of the weld. In addition, the on-site welding process is complex and takes a long time, which restricts the whole process. Construction speed of the structure.

目前,装配式施工方法一直为国家所倡导,而装配式钢结构建筑的技术难点主要集中在梁柱连接节点上。在钢结构建筑中,梁柱连接节点传统上有三种连接形式:①上下翼缘为全熔透焊缝连接,腹板用高强度螺栓连接,即栓焊混合连接;②翼缘和腹板均为焊缝连接,即全焊接连接;③上下翼缘和腹板都用高强度螺栓连接,即全螺栓连接。对于前两种连接方式,梁上下翼缘为全熔透连接,施工中需要先安装再施焊,而采用焊接方法,可能会导致质量事故及引发火灾,且施工速度也会受到较大影响。At present, the prefabricated construction method has been advocated by the state, and the technical difficulties of prefabricated steel structure buildings are mainly concentrated on the beam-column connection nodes. In steel structure buildings, there are traditionally three connection forms for beam-column connection nodes: (1) the upper and lower flanges are connected by full penetration welds, and the webs are connected by high-strength bolts, that is, a hybrid connection of bolted welding; (2) both flanges and webs are connected. It is a welded seam connection, that is, a full-welded connection; ③ The upper and lower flanges and the web are connected with high-strength bolts, that is, a full-bolt connection. For the first two connection methods, the upper and lower flanges of the beam are fully penetrated connections, which need to be installed and then welded during construction. However, the use of welding methods may lead to quality accidents and fires, and the construction speed will also be greatly affected.
