Description

一种防腐钢结构支架
技术领域
本发明涉及一种钢结构支架，具体是一种防腐钢结构支架。
背景技术
支架是各种建筑物中必须具备的结构，现有的支架通常采用工字钢替代，其抗弯强度较差，容易变形弯曲，进而造成建筑物结构不稳定，带来一定的安全隐患，而且支架经长时间使用后会被锈蚀，也会影响受力构件的整体强度。
发明内容
本发明的目的是提供一种防腐钢结构支架，该支架不仅结构强度高，不易变形，而且有很好的防腐效果，大大提高了建筑物的结构强度。
为实现上述目的，本发明采用的技术方案是：一种防腐钢结构支架,包括一横梁、一对斜梁以及若干加强筋；所述横梁为工字钢，所述斜梁的两端分别设置有法兰，所述斜梁一端的法兰与横梁相焊接，其另一端的法兰与相连斜梁的法兰通过螺栓相连接，所述加强筋焊接在横梁和斜梁之间，所述横梁上还设置有肋板；
所述横梁、斜梁、加强筋和法兰的外表面均喷涂有防腐涂层；所述防腐涂层自内向外依次为铝镁合金金属涂层、封闭底漆层、丙烯酸聚氨酯面漆层；所述铝镁合金金属涂层的厚度为180μm～220μm，所述封闭底漆层的厚度为30μm，所述丙烯酸聚氨酯面漆层的厚度为90μm。
进一步，所述若干加强筋呈M形布置。
进一步，所述横梁和斜梁排布成三角形结构。
本发明的有益效果是：所述防腐钢结构支架不仅结构强度高，不易变形，而且横梁、斜梁、加强筋和法兰的外表面均喷涂有防腐涂层，具有很好的防腐效果，横梁上设置有肋板，使得支架的稳定性更好，大大提高了建筑物的结构强度。
附图说明
图1是本发明的结构示意图；
图2是防腐涂层的示意图；
图中，1.横梁，2.斜梁，3.加强筋，4.法兰，5.肋板，6-1.铝镁合金金属涂层，6-2.封闭底漆层，6-3.丙烯酸聚氨酯面漆层。
具体实施方式
下面结合附图对本发明作进一步详细说明。
如图1、2所示，一种防腐钢结构支架,其特征在于,包括一横梁1、一对斜梁2以及若干加强筋3；所述横梁1为工字钢，所述斜梁2的两端分别设置有法兰4，所述斜梁2一端的法兰4与横梁1相焊接，其另一端的法兰4与相连斜梁2的法兰通过螺栓相连接，所述加强筋3焊接在横梁1和斜梁2之间，所述横梁1上还设置有肋板5，从而使横梁1承载能力加强，使得支架的稳定性更好；
所述横梁1、斜梁2、加强筋3和法兰4的外表面均喷涂有防腐涂层；所述防腐涂层自内向外依次为铝镁合金金属涂层6-1、封闭底漆层6-2、丙烯酸聚氨酯面漆层6-3；所述铝镁合金金属涂层6-1的厚度为180μm～220μm，对钢结构支架进行阴极保护，所述封闭底漆层6-2的厚度为30μm，这样可以对铝镁合金金属涂层6-1的缝隙进行封闭，所述丙烯酸聚氨酯面漆层6-3的厚度为90μm，将内部涂层与空气隔离开，从而起到很好的防腐效果。
进一步，所述若干加强筋3呈M形布置，通过设置M形布置的加强筋3，使得该支架的结构强度更高。
进一步，所述横梁1和斜梁2排布成三角形结构，从而使该支架的承载能力更强，不易发生弯曲变形。
所述防腐钢结构支架不仅结构强度高，不易变形，而且横梁、斜梁、加强筋和法兰的外表面均喷涂有防腐涂层，具有很好的防腐效果，横梁上设置有肋板，使得支架的稳定性更好，大大提高了建筑物的结构强度。
