Description

金属制可膨胀锚栓
技术领域
本发明涉金属制可膨胀锚栓，用来将一个构件固定到一个基础上，所述可膨胀锚栓包括具有内螺纹的锚栓基础部分，该基础部分可插入在基础中的钻孔中且具有膨胀部分，在膨胀部分上轴向可移动地安装有一个膨胀套筒，且其中可膨胀锚栓具有压缩元件。
背景技术
为了将物品固定在基础上，经常要求使用的可膨胀锚栓具有高的抗拉出强度且允许使用螺钉或螺纹杆。为了实现这个目的需要具有内螺纹的金属制造的可膨胀锚栓。而且，在通常发生裂纹的拉力区域内的固定需要可膨胀锚栓的后膨胀性能(Nachspreizverhalten)。由于通常由敲击锚栓公知的可膨胀锚栓没有连续膨胀的能力，文献EP0995914A2提出了一种可膨胀锚栓，其锚栓基础部分具有内螺纹和在其上安装有能够轴向移动的膨胀套筒的膨胀部分。当锚栓基础部分被拉入膨胀套筒后导致可膨胀锚栓被固定，其中膨胀套筒在钻孔中径向夹紧而不会产生轴向移位。此外该文献还提出可膨胀锚栓预先装配地具有带有套筒状放置的压缩元件(Stauchelement)的螺钉。螺钉被旋进锚栓基础部分的内螺纹中，使压缩元件的一端靠在螺钉头上且另一端靠在锚栓基础部分面对螺钉的端面上。压缩元件确保在可膨胀锚栓装入钻孔时，锚栓基础部分被充分地与螺钉头很远地隔离，以使得锚栓基础部分能够被充分地拉进膨胀套筒内而不会与螺钉头提前接触。在此过程中，压缩元件沿轴向压缩。
这样布置的缺点是压缩元件仅仅能够被用来与预先装配的螺钉连接。然而，如果需要特别长的螺钉或螺纹杆进行固定时，例如因为应当固定特别大的构件或因为锚栓应当用来从天花板悬挂管子时，具有压缩元件的预先装配的螺钉就不适合了。
发明内容
本发明的任务在于提供一种金属制连续膨胀的且具有内螺纹的可膨胀锚栓，其适用于不同长度的螺钉，螺纹杆等。
根据本发明，该任务通过一种金属制可膨胀锚栓解决，所述可膨胀锚栓用来将一个构件固定到一个基础上，所述可膨胀锚栓包括具有内螺纹的一个锚栓基础部分，该基础部分可插入在基础中的一个钻孔中且具有一个膨胀部分，在膨胀部分上轴向可移动地安装有一个膨胀套筒，且其中可膨胀锚栓具有一个压缩元件，压缩元件设在锚栓基础部分中。根据本发明的可膨胀锚栓具有设在锚栓基础部分中的压缩元件。由此，可膨胀锚栓能够使用不同长度的螺钉安装，例如为了固定不同尺寸的物品。螺钉被旋进可膨胀锚栓的内螺纹直到其导入端顶靠在径向压缩元件上。压缩元件的另一端顶靠在内螺纹钻孔的底部上的、相应的突肩或类似物上。由此，使用者将注意到旋进扭矩的明显增大，这表示可膨胀锚栓能够在这样的状态下安装在基础的钻眼中。可膨胀锚栓被推进直到螺钉头靠在基础或位于其间的垫圈和/或待固定构件。为了膨胀可膨胀锚栓，螺钉被进一步旋进内螺纹。因为螺钉头用作支座，锚栓基础部分逆着进入方向被拉，由此，膨胀静止的膨胀套筒。同时，压缩元件遭受压缩。与螺钉的初始旋进相比，需要使用更高的扭矩实现此过程，从而要有工具的帮助，需要确定压缩元件的压缩能力，以在膨胀过程中不会由于压缩在扭矩方面有明显的的增加，直到膨胀套筒获得适当的膨胀。从而，也就是说，通过膨胀套筒的膨胀而不是由压缩元件的压缩引起扭矩进一步的增加。在膨胀完成后，如果螺钉已经满足了固定的需要就将螺钉保持在可膨胀锚栓中，或者其被旋出而替代地例如旋入螺纹杆。在后一种情况下，螺钉被仅仅理解为一种安装工具。
压缩元件优选是塑料套筒。这允许能够通过以一定的长度切割的管子简单地制造。然而，除了这样，其他的材料和形状也是可行的，如钢制的压缩弹簧。而且，径向压缩元件最好以不易丢失的方式设在锚栓部分中，例如通过压配合插入或旋入脚螺丝部分的内螺纹中。因此，在储存、运输或倒置安装的过程中不会丢失压缩元件。
具体实施方式
参考附图描述的实施例，下面将更加详细的介绍本发明。图1显示了根据本发明的用于将构件2固定到基础3的在膨胀前状态下的可膨胀锚栓1。可膨胀锚栓1由钢制造且具有有内螺纹5的锚栓基础部分4。锚栓基础部分4具有直径逐渐减小的膨胀部分6，膨胀部分6沿着与可膨胀锚栓1的进入方向相反的方向逐渐变细，且在膨胀部分6上安装有能够轴向移动的膨胀套筒7。由塑性材料制造的套筒状压缩元件9置于锚栓基础部分4的内螺纹5的钻孔底部8上。其外部直径经过选择，使得通过轻微的压配合插入就使得其以不易丢失的方式设在锚栓基础部分4中。
在可膨胀锚栓1装入在基础3中的钻孔10之前，螺钉11与垫圈12一起被旋进锚栓基础部分4的内螺纹5中，直到插入端13开始顶靠在压缩元件9上。在这样的状态下，可膨胀锚栓1被推进钻孔10中直到垫圈12与螺钉的头部14开始顶靠在待固定的构件2上。在这种情况下，锚栓基础部分4的一部分伸进待固定的构件2贯通钻孔15中。由此，锚栓基础部分4同时定中地作用于构件2上且必要时受横向力的作用。如果与期望不同，只需要简单的选择对应的更长的螺钉。
为了可膨胀锚栓1的膨胀，螺钉11被拧紧。膨胀套筒7与钻孔内壁16和锚栓基础部分4的膨胀部分6的接触导致锚栓不能转动。从而，锚栓基础部分4逆着可膨胀锚栓1置入的方向被拉，膨胀套筒7沿着轴向在膨胀部分上滑动，从而通过膨胀固定锚栓1。同时，压缩元件9轴向压缩且被径向向里挤。压缩元件9的材料与几何形状在这里彼此协调以使得非常容易的产生压缩，至少是螺钉11为膨胀套筒7的膨胀而必需的旋进的距离。
