Description

新型变电架构“A”型柱与格构式钢梁连接结构
技术领域:
本实用新型涉及一种新型变电架构“A”型柱与格构式钢梁连接结构,属于变电站架构领域。
背景技术:
变电站架构通常采用“A”型柱与正三角形格构式钢梁组成的排架结构方案,采用三角形钢梁中的两根水平主材(下弦)与“A”型柱铰接连接,三角形钢梁的另一根主材(上弦)不直接参与架构整体受力。造成三角形钢梁的抗扭、抗弯刚度较小,导致梁侧垂挂点处产生的位移较大,易发生钢梁失稳破坏,并且在长期动荷载作用下结构安全可靠度较差;同时在有侧垂挂点的受力情况下,钢梁的主材和斜材内力较大,从而使钢梁整体材料用量增大。
实用新型内容:
本实用新型的目的在于提供一种提高格构式三角形钢梁的抗扭刚度,增强变电架构整体受力性能的新型变电架构“A”型柱与格构式钢梁连接结构。
本实用新型由如下技术方案实施:新型变电架构“A”型柱与格构式钢梁连接结构,其包括格构式三角形钢梁和变电架构“A”型柱,所述格构式三角形钢梁下弦的两根水平主材与所述变电架构“A”型柱顶端铰接;在所述变电架构“A”型柱顶端焊接有连接短柱,所述连接短柱与所述格构式三角形钢梁上弦的第三根主材固定连接。
本实用新型的优点:增加格构式三角形钢梁的抗扭、抗弯强度;架构梁柱各结构构件联合受力,可减小结构中个别内力较大构件的应力,节省钢材量;使结构受力合理,提高结构安全可靠度;增加门型架构侧向刚度。
附图说明:
图1为本实用新型的整体结构示意图。
格构式三角形钢梁1、变电架构“A”型柱2、主材3、连接短柱4。
具体实施方式:如图1所示,新型变电架构“A”型柱与格构式钢梁连接结构,其包括格构式三角形钢梁1和变电架构“A”型柱2,格构式三角形钢梁1下弦的两根水平主材3与变电架构“A”型柱2顶端铰接;在变电架构“A”型柱2顶端焊接有连接短柱4,连接短柱4与格构式三角形钢梁1上弦的第三根主材3固定连接。
工作原理:本实用新型把格构式三角形钢梁1上弦的主材3端部通过连接短柱4与变电架构“A”型柱2连接,使格构式三角形钢梁1上弦的主材3也直接参与架构整体受力。
