Abstract

本实用新型涉及管件,是一种异型钢管,该钢管的管壁沿钢管径向设有两处凸起管壁,两处凸起管壁相对于钢管呈对角设置,且两者均沿钢管整长设置。所述钢管一处凸起管壁的壁厚小于另一处凸起管壁的壁厚,且两处凸起管壁的壁厚均大于钢管未凸起管壁的壁厚。将钢管两处的凸起管壁设计为尺寸一大一小,从而方便根据实际外力分配钢管受力面,相比现有厚度一致的异型钢管能更好的适应抗弯、抗扭强度,适合作为市面上柠檬型钢管的改进使用。

Description

异型钢管
技术领域
本实用新型涉及管件,是一种异型钢管。
背景技术
异型钢管是除了圆管以外的其它截面形状的钢管的总成。按钢管截面形状尺寸的不同又可分为等壁厚异型钢管、不等壁厚钢管、变直径异型钢管等。异型钢管广泛应用于各种结构件、工具和机械零部件,和圆管相比,异型钢管一般都有较大的惯性矩和截面模数,有较大的抗弯抗扭能力,可以大大减少结构重量,节约钢材。但现有某些异型钢管,例如市面上销售的柠檬型异型钢管,其壁厚大都采用均等壁厚设计,未充分考虑抗弯和抗扭能力,使得异型钢管耗费了过多材料,却没有提高钢管抗弯、抗扭的适应能力。为此,有待对现有柠檬型异型钢管进行改进。
实用新型内容
为克服上述不足,本实用新型旨在向本领域提供一种异型钢管,使其解决现有同类钢管,抗扭、抗弯能力欠佳的技术问题。其采用如下技术方案实现。
该异型钢管的管壁沿钢管径向设有两处凸起管壁,两处凸起管壁相对于钢管呈对角设置,且两者均沿钢管整长设置。所述钢管一处凸起管壁的壁厚小于另一处凸起管壁的壁厚,且两处凸起管壁的壁厚均大于钢管未凸起管壁的壁厚。将钢管两处的凸起管壁设计为尺寸一大一小,从而方便根据实际外力分配钢管受力面,使钢管达到较佳的抗弯抗扭性能。
所述钢管的凸起管壁呈弧形或矩形。
所述钢管的凸起管壁与未凸起管壁之间呈圆弧过渡。该结构有效减少使用过程中凸起管壁与未凸起管壁之间的疲劳磨损。
所述钢管的凸起管壁沿钢管整长直线设置。该结构有利于抗弯。
所述钢管的凸起管壁沿钢管整长螺旋设置。该结构有利于抗扭。
本实用新型相比现有厚度一致的异型钢管能更好的适应抗弯、抗扭强度,适合作为市面上柠檬型钢管的改进使用。
附图说明
图1是本实用新型的端面结构示意图,图中D1、D2、D3表示管壁厚度。
图中编号及部件的名称为:1、钢管,101、凸起管壁,102、未凸起管壁。
具体实施方式
现结合附图,对本实用新型作进一步描述。
如图1所示,该异型钢管的管壁沿钢管1径向设有两处呈弧形的凸起管壁101,该两处凸起管壁101相对于钢管1呈对角设置,且两者均沿钢管1整长直线设置。钢管1一处凸起管壁101的壁厚D1小于另一处凸起管壁101的壁厚D3,且两处凸起管壁101的壁厚均大于钢管1未凸起管壁102的壁厚D2,凸起管壁101与未凸起管壁102之间呈圆弧过渡。
上述结构中,可将钢管1的凸起管壁101设计为矩形,以提高抗弯强度。或将钢管1的凸起管壁101沿钢管1整长螺旋设置,使其类似弹簧的螺旋样式,以利于提高抗扭强度。
以上内容旨在说明本实用新型的技术手段,并非限制本实用新型的技术范围。本领域技术人员结合现有公知常识做显而易见的改进,亦落入本实用新型权利要求的保护范围之内。
