Description

一种板材用锚栓 技术领域
本发明属于建筑锚栓的技术领域，特别涉及一种适用于蜂窝板材及其它板材的建筑锚栓。
背景技术
传统的建筑锚栓如图1所示，由螺母100、螺杆200及膨胀件300组成，螺杆200的里端具有楔形头201，膨胀件300呈管状且里端具有膨胀片301，膨胀件300套在螺杆200上，其膨胀片301抵在楔形头201上，螺母100螺套在螺杆200的外端。
安装时，将套有膨胀件300的螺杆200插入钻好孔的被锚固件中，再将外挂物挂置在螺杆200的外端，然后，将螺母100螺套在螺杆200上，通过旋拧螺母100向墙孔内推挤膨胀件300，使膨胀件300的里端膨胀片301在楔形头201的导引下胀开，紧紧抓住孔的内壁，而令整个锚栓固定在被锚固件的孔中，达到将外挂物固定在建筑上的目的。
上述锚栓因为膨胀件300膨胀片301可膨胀量小，与被锚固件孔的接触面小，抓紧力不足，而且，膨胀片301伸入被锚固件中，若使用在蜂窝板材内，容易出现膨胀片301恰好处于空穴中的情形，如图2所示，导致锚固无效。
有鉴于此，本发明人研发出一种新型锚栓，其结构简单，可有效锚固，本案由此产生。
发明内容
本发明的目的在于提供一种板材用锚栓，其结构简单，具有良好的锚固功效。
为了达成上述目的，本发明的解决方案是：
一种板材用锚栓，由螺母、螺杆及膨胀件组成；螺杆的外端具有螺纹段而里端具有螺栓头；膨胀件包括平垫和膨胀管，膨胀管上开有利于膨胀的剖槽，膨胀件套置在螺杆上，膨胀管的里端抵在螺栓头上；螺母旋拧在螺纹段上，螺母抵在平垫上。
所述平垫和膨胀管分体成型再组接形成膨胀件，膨胀管由片材弯折而成，膨胀管与平垫的组接端形成接头，平垫的内缘形成插槽，膨胀管借助接头插置在插槽中而与平垫组接在一起。
所述螺栓头靠膨胀件的一侧形成导引膨胀管产生膨胀变形的斜撑面。
采用上述结构后，本发明安装时，在被锚固件上钻孔，将膨胀件套在螺杆上，再将螺杆的螺栓头朝里插在预先钻好的孔中，然后，将螺母旋在螺杆的螺纹段上，拧紧螺母时，膨胀管受螺栓头挤压沿剖槽胀开，直径增大，使被锚固件被变形后的膨胀管和平垫夹紧固定，再将螺母旋下，最后，将外挂物挂置在螺杆上，将螺母旋在螺杆的螺纹段上，达到将外挂物固定在建筑上的目的。
本发明膨胀件的膨胀管在压缩后高度大大压缩，膨胀管由管状撑开成片状，可膨胀量很大，与被锚固件孔的接触面大，抓紧力倍增，而且，膨胀片紧贴被锚固件，所以，本发明可确保良好的锚固功效，适用于蜂窝板材及其它板材。本发明结构简单，加工制作方便。

具体实施方式
如图3和图4所示，是本发明的较佳实施例，由螺母1、螺杆2及膨胀件3组成。
螺杆2的外端具有螺纹段21而里端具有螺栓头22。螺栓头22靠膨胀件3的一侧形成斜撑面23，用于导引膨胀件3产生膨胀变形。
膨胀件3包括平垫31和膨胀管32，膨胀管32上开有利于膨胀的剖槽35，膨胀件3套置在螺杆2上，膨胀管32的里端抵在螺栓头22上。其中，平垫31和膨胀管32可以是图3所示的铸造成型为一体，或如图7所示，平垫31和膨胀管32分体成型，再组接形成膨胀件3，膨胀管32由冲压的片材弯折而成，膨胀管32与平垫31的组接端形成接头33，平垫31的内缘形成插槽34，借助接头33插置在插槽34中而将膨胀管32与平垫31组接在一起。
螺母1旋拧在螺杆2的螺纹段21上，螺母1旋拧在螺杆2上后则抵在平垫31上。
本发明实施例一安装时，如图4所示，在被锚固件4上钻孔41，将膨胀件3套在螺杆2上，再将螺杆2的螺栓头22朝里插在预先钻好的孔41中，然后，将螺母1旋在螺杆2的螺纹段21上，如图5所示，拧紧螺母1时，使膨胀管32高度被压缩而直径增大，被锚固件4与膨胀管32夹紧被锚固件4固定，最后，将螺母1旋下，如图6所示，将外挂物5挂置在螺杆2上，再将螺母1旋在螺杆2的螺纹段21上，达到将外挂物5固定在建筑上的目的。实施例二的安装方式与实施例一相同，故不赘述。
以上所述仅为本发明的几个实施例，并非对本案设计的限制，凡依本案的设计关键所做的等同变化，均落入本案的保护范围。
