Abstract
通过组成基团的相互反应，在树脂硬化的基础上使多个构件凝结为一个组合结构的固接套，包括一个装有树脂和填充物的内套，以及一个装有硬化剂的外套。为了能够以手动方式使固接杆充分就位，并且在杆的就位过程中不出现溅出和流失的现象，以及为了能够在树脂和硬化剂中使用填充物以增加强度，内外套之间环形空间的宽度至少与套的壁厚相等，至多为外套外径的5%。此外，树脂含有触变剂，它使树脂的粘度增加到足以使填充物颗粒悬浮在树脂中。由液体(非必须的)填充物和触变剂组成为糊状混合体的硬化剂完全充满于内外套之间的环形空间中。
Description
本发明涉及如权利要求1前序部分所述的固接套，它通过组成基团的相互反应，[例如聚酯树脂、乙烯酯树脂或(甲基)丙烯酸酯树脂]，在树脂硬化的基础上使多个构件凝结成一个组合结构。
参照德国专利DE-OS3806598即可了解上文所述的这类固接套，它的内套中装有树脂，它的外套中装有硬化剂。为了在内套和外套之间形成和保持一个环形的空间，使用了包覆有过氧化苯酰的石英砂。然而，由于两个套之间的填充料含有不同尺寸的颗粒，较小颗粒的填充料位于前部，粗大颗粒的填充料位于后部，这就使得固接杆向钻孔中的引入变得十分困难，尤其在手动作业时更是困难。不同尺寸的颗粒以及由此产生的不同尺寸的表层进而又造成环形区域中的硬化剂在同心度方面的差异，因此使硬化过程不均匀。
为了避免这些缺陷，在Upat UES钢杆固接中，为了将内套固定在外套中，建议使用过氧硬化物和聚合填充物的混合体。然而，这种粉末形式的混合体要求只能有很小的环形空间，才能避免硬化体沉落到内外套之间的环形空间的底部。另外，这种粉末对钻孔壁只有轻微的清洁作用，因此，粘在钻孔壁上的钻屑降低了凝结强度。为了弥补这点，把内套中灌装的树脂的粘度调得很低，以便充分湿润钻孔壁。然而这种结构的缺陷在于，在锤击固接杆使之就位时，低粘度的树脂从钻孔中溅出或流失(在墙上作业时)。此外，树脂中无法使用填充物，这是因为填充物具有较高的密度，它们会沉落到套的底部。尤其是在(楼层)地面作业时，沉落到套的底部的填充物将使得固接杆的充分引入变得非常困难。
本发明的目的在于改进固接套的组合结构，使得能够通过手动作业引导固接杆充分就位，并且在引导固接杆就位的过程中不会发生固接剂溅出或流失的现象，而且在树脂和硬化剂中都可以使用填充物以增加结合强度。
这一目的通过权利要求1记载的特征而得以实现。
通过将环形空间设置成至少与固接套的壁厚相等、至多等于外套外径的5％，两个套便很容易被压碎，并且可以获得树脂和硬化剂之间能够很好混合的合适的体积比。此外，在树脂和硬化剂中可以采用其颗粒尺寸最多等于玻璃套的壁厚尺寸的填充物。通过将硬化剂与液体(例如水或有机溶剂)、某种适当的触变剂、以及(非必须的)填充物相混合，增加了硬化剂的体积比例，以形成完全充满了内外套之间环形空间的糊状剂。糊状剂的高粘度即使在环形空间具有较大尺寸的情况下也能防止沉淀，能够保证硬化剂在所涉及的套的整个长度上均匀地分布。
此外，触变剂将树脂的粘度增加到能够防止填充物发生沉淀现象的程度。树脂粘度的增加同时也能在就位作业时防止树脂的溅出和流失。固接套中两种组分的均匀分布，(其中，树脂含有附加的填充物，硬化剂中也可以含有填充物)，保证了能够实现组合物件的均匀和充分的硬化、合成树脂浆硬化后的高强度、以及钻孔壁与合成树脂浆之间的良好的结合强度。
水泥基的活性无机粘结剂被证明是树脂组分中特别有益的填充物。在这种情况下，最好使用热解(Pyrogenic)硅酸作为树脂组分的触变剂。硬化剂组分中以玻璃珠为填充物，以疏水性热解硅酸为触变剂。当硬化剂中所含的液体(例如水)与无机粘结剂化合时，无机粘结剂增强了树脂-硬化剂混合体的流动。因而树脂-硬化剂的混合体变得更加液化。当使用热解硅酸作为触变剂时，它具有这样的特性：当引入固接杆以及由此产生的剪切力作用于树脂-硬化剂的混合体时，使树脂和硬化剂的粘度都降低了，因而促使两种组分更好地混合并且使固接杆的引入更加容易。混合在糊状硬化剂中的玻璃珠一方面增加了硬化后的多元件组合构件的抗压强度，另一方面保证了内外套之间环形空间的匀称的对中效果。
钢珠也可以作为树脂组分中的填充物。在这种情况下，使用热解硅酸作为树脂和硬化剂中的触变剂，用奈烷(十氢化奈)作为硬化剂中的液体成分。
由不锈钢制成的钢珠其直径为10～50μm，最好是22μm。这一方面保证了混合体具有很好的流动性以降低固接杆引入时所需的能量，另一方面避免了沉淀现象。
硬化剂是由萘烷与硬化物构成的糊状混合体，因而保证了树脂与硬化物之间的较大的混合界面。热解硅酸防止了硬化物与萘烷相分离。当硬化剂与树脂混合时，萘烷分解，这样就只在树脂与硬化物之间发生反应。
为了使玻璃固接套破碎后的碎片尽可能地小，最好使外套的外径等于或小于固接杆的外径。
为了使硬化后的多元件结构获得令人满意的强度，包括固接套玻璃碎片在内的填充物的总量应为2～3.5倍于树脂。由于树脂和硬化剂中已经包含了填充物，固接套的壁厚可以限定在0.3～0.5mm之间，因而也降低了固接杆引入时所需的能量。

通过组成基团的相互反应，[例如聚酯树脂、乙烯酯树脂、或(甲基)丙烯酸酯树脂]，在树脂硬化的基础上使多个元件凝结成一个组合结构的玻璃固接套，包括一个外套1和一个内套2，内套位于外套内并通过外套中灌装的硬化剂3而与外套同心，以形成一环形空间4。内套2灌装了混有填充物6的树脂5。呈现为糊状混合物的硬化剂也可以含有填充物，例如玻璃珠7。
固接套插在建筑构件9的钻孔8中。通过挤入一个带有锲形尖端10的固接杆11，固接套被挤破，套中所含的组分相互反应。为了降低引入固接杆时，特别是用手锤以手动方式使固接杆就位时所需的能量，固接杆11的外径应略小于外套1的外径。此外，套的壁厚为0.3～0.5mm，环形空间4的宽度至少与套的壁厚相等，至多为外套外径的5％。
