Description

一种墙体对拉螺杆
技术领域
本实用新型涉及一种建筑用螺杆,具体涉及一种用于混凝土墙体施工的墙体对拉螺杆。
背景技术
墙体对拉螺杆是混凝土墙体施工中不可或缺的配件。目前,在混凝土墙体施工中,由于所使用的墙体对拉螺杆的螺纹细,螺距小,因此,存在有抗拉强度低、安装速度慢以及螺纹容易损坏等问题和不足。
实用新型内容
本实用新型的目的是针对现有技术的不足,提供一种设计合理、结构简单、抗拉强度高且安装快捷的墙体对拉螺杆。
为实现上述目的,本实用新型采用的技术方案是:一种墙体对拉螺杆,包括外圆上设置有螺纹的杆体和安装在杆体两端与所述螺纹相啮合的螺帽,其特征在于:所述螺纹的牙形下宽上窄,且顶部为圆弧形。
所述螺纹的螺距P为3.5-6mm。
本实用新型与现有技术相比具有以下优点:
本实用新型设计合理,结构简单,抗拉强度高,螺纹不易损坏,现场使用方便,安装速度快。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型作进一步的描述。
如图1所示,本实用新型包括外圆上设置有螺纹的杆体1和安装在杆体1两端与所述螺纹相啮合的螺帽2,所述螺纹的牙形下宽上窄,且顶部为圆弧形。
所述螺纹的螺距P为3.5-6mm,螺距P优选为5mm。
由于本实用新型对拉螺杆的螺纹采用下宽上窄、顶部为圆弧形的牙形,因此提高了螺纹的抗拉强度,增加了螺杆的紧固力,延长了螺杆的工作寿命。由于螺纹采用3.5-6mm的大螺距,从而加快了螺帽在螺杆上的安装速度。

Claims (2)
