Abstract

一种在内端向外扩大的钻孔中锚定的膨胀螺栓。对于内端逐渐扩大的钻孔，螺栓有一个膨胀锥放在钻孔底上，其上可套上一个可推动膨胀套筒。将本发明的可膨胀套筒套上，将伸出钻孔的固定部用螺丝扳手或类似工具拧旋，膨胀锥用螺纹和固定部连接，并被防止随固定部旋转。这样可取得非常简化的组合件，使用不同长度的螺纹锚杆可适应待夹定构件的不同夹紧长度。

Description

本发明涉及在内端扩大的钻孔中锚定的膨胀螺栓，有一根锚杆其上有一个膨胀锥，对钻孔底部作用，外套一可膨胀套筒，在长度的一部分上有裂缝，膨胀锥用螺纹和一个固定部连接。
用有扩大部的钻孔，可以取得基本没有膨胀压力的锚定，而且因为可以增大固定件的膨胀，甚至可产生更高的夹持数值。已知的膨胀螺栓有一个膨胀锥，用适当的锤击工具将一个可膨胀的套筒套在锥体上。可将膨胀锥制造在一个锚杆上，用螺纹接头连接螺纹锚杆。螺纹锚杆的另一端伸出钻孔，可以有一段外螺纹，在上面拧一个螺母，将需要固定的物件在外墙或顶板上紧固。
已知的膨胀螺栓可以锤入一个有锥形掏切部分的钻孔，需要用特殊的工具，且不能方便适应需固定的物件的不同夹持长度。
本发明的目的，是生产一种膨胀螺栓，用于在内端扩大的钻孔中固定，易于安装，便于适应需固定的物件的不同夹持长度。本发明对这个问题的解决办法，是在前言中提及的类型的膨胀螺栓中，将固定部分相对于锚杆旋转，将膨胀套筒压在膨胀锥上，在膨胀锥的端面上，至少有一个紧固件作防止旋转的措施。作为防转措施，可用突出部，棱脊，或有同体模铸的尖刺在钻孔底对砌体作用，将锚杆固定，防止作不利的旋转。固定部构造最好是螺纹锚杆，可用适当的工具按锚杆方向拧入，该螺纹锚杆将可膨胀套筒推到膨胀锥上。
因此在可膨胀套筒和螺纹锚杆间有尽可能小的摩擦，本发明的一种发展，放一个低摩擦元件在固定装置和可膨胀套筒之间。最好用一个有锚杆螺纹部贯通通道的塑料垫圈，作为低摩擦元件。
此外，可以有和膨胀套筒上的纵向裂缝嵌合的紧固件，从膨胀锥上侧向突出。安装时，仅将膨胀套筒稍膨胀，膨胀套筒便对钻孔壁挤紧，于是膨胀锥和紧固件配合，形成锚杆的防转措施。
为放置螺丝搬手或其它工具，可在螺纹锚杆的突端设六角形头或平侧面。
下文中参照附图对本发明作说明，附图内容如下：
图1示插入钻孔的膨胀螺栓，
图2示图1中插入钻孔的膨胀固定塞膨胀锥的端面，
图3示膨胀锥另一举例实施方案的端面。
图1所示膨胀螺栓插入一个钻孔1中，钻孔1在底部区域的内端向外扩大。
膨胀螺栓有一根锚杆2，上有一个膨胀锥3，一个可膨胀套筒4，和一个螺纹锚杆5，螺纹锚杆有一个固定部。螺纹锚杆5的从钻孔1向外伸出的膨胀螺栓的端部，有一个外螺纹6，在上面用螺母将物件8夹紧。因此将物件8压在墙体9的外表上。
锚杆2的螺纹部分10拧在螺纹锚杆5的螺纹孔11中。假如在加螺母7前，将螺纹锚杆5相对于锚杆2旋转，于是锚杆5便向膨胀锥3靠近。这样膨胀套筒4便被向膨胀锥推送，直至达到图中的位置。当将膨胀套筒4向前推时，因设有一个最好用塑料制的低摩擦圆盘12，螺纹锚杆5和膨胀套筒4之间便产生尽可能小的摩擦力。
将螺纹锚杆5旋转时，螺纹锚杆5被压入钻孔中，使铸在膨胀锥3端面上的紧固件13，对钻孔底作用，这里的紧固件是一个突块。这样，可保证锚杆2在螺纹锚杆旋转时不随之旋转。
作为防止不利旋转的另一元件14，是插入膨胀套筒4的纵向裂缝15的一个突出部，元件14在膨胀锥3的边侧上形成。膨胀套筒3一待紧固就位便不能旋转，由于在钻孔中稍膨胀，突出部14便成为防旋转的理想 措施。
紧固件13，14仅为可采用的方案;突耳，尖刺或其他类似的结构也都可使用。
为了便于在螺纹锚杆5的外部上放螺丝搬手或其他工具，螺纹锚杆5有边侧上的平表面或六边形头16。但是此外也可设其他的形状，使适当的工具可以稳定配合。
图2示膨胀锥3的端面，紧固件13的结构为向外倾斜的突块。
图3示膨胀锥3的另一举例方案，端面上有紧固件17，结构可以是突出部或尖刺。
