Description
本发明涉及一种用于混凝土结构施工缝的灌浆软管,其具有基体与外套,基体由橡胶或塑料之类的柔性材料构成,本质上为不透过液体且包围着通道,并在它的外壳表面设置有至少一个延伸于其长度方向的沟状凹槽,在其内分布有遍及凹槽全长的径向孔口,以供灌浆从通道流出,并且容纳着覆盖孔口的条带,它是由在灌浆的内压下可被压缩的材料构成,而外套是软管状且可透过液体,包围着基体与条带。
一种用于混凝土结构施工缝之灌浆软管是从DE-GM 8,425,518得知公开了,其具有能透过液体而由如橡胶或塑料之类的柔性材料所构成,本质上为圆筒形的管壁,该管壁具有延伸于其长度方向以供灌浆流出的狭缝,管壁在狭缝的部位具有同样是沿其长度方向轴向延伸的凹槽,用于容纳覆盖狭缝的条带能在灌浆的压力下由可压缩的材料构成,该管壁连同条带是被能透过液体的材料所制成的软管所包围。这种灌浆软管在制造上有缺点,而且,由于出口狭缝比凹槽的宽度较狭窄的缘故,需要比较高的灌注压力,因此不能可靠地使灌浆均匀地分布于灌浆软管的圆周。
这些缺点在从DE-OS3,512,470所公开的灌浆软管内已尽可能地被克服了。它借助于在基体内设置多个径向孔口,并使对应的凹槽与条带呈角对称于纵向轴中心地分布于基体的圆周。但是,它需要较高的制造费用。
本发明的目的是要提供一种在开头所述的,制造起来简单,且以较低的灌注压力就能使灌浆均匀地分布于灌浆软管的圆周,即使使用水泥也能可靠地灌浆到施工缝。
本发明的这个目的是借助于:或者以预定的间距螺旋地环绕基体的外壳表面的唯一凹槽,或者与通道轴向平行延伸但是开口角度大于90度的唯一凹槽,而实现了。
借助于此两个解决途径,灌浆软管的制造简化了,因为只需在基体的外壳表面设置唯一的凹槽,另一方面,在基体内穿过的狭缝的缺点也被克服了,因为在基体上设置了遍及基体全长的径向通孔,同时,或者基于螺旋状的凹槽构形或者基于凹槽的较大宽度,达到意外地将灌浆非常均匀地分布于灌浆软管的圆周,使得施工缝能更可靠地被封闭。
如果以大网孔而不会变形的织物,来制作紧紧包围着基体外壳表面的及条带外表面的外套,那会是特别有利的,因为以这种方式,在加压于灌浆期间,灌浆软管的圆周丝毫不会扩大,只不过基于条带材料的受挤压而产生了内部阀门效果而已。这是因为当存在例如混凝土的外部压力时,条带封闭了沟状凹槽内的孔口,且外部压力愈大,效果愈好。当受到来自内部压力的挤压时,灌浆就容易涌出,由于条带是以不会变形的织物制成的,因此灌浆软管不会改变其横断面,否则就会导致施工缝的不完全封闭。
本发明的另一构成是,宽度较大的凹槽与通道轴向平行延伸,并将通道配置得偏心于圆筒形基体,可带来材料的节省。
在制造技术上,若是在预应力情形下,将条带胶粘于凹槽内,是有利的。
在本发明的范围内,是可以有利地使凹槽及条带的侧边界面,以本来是公知的方式,互相从径向的外边倾斜到径向的内边。这样,就产生了当有来自内部的灌注压力时特别有利的孔口断面,以及当有来自外部的压力时特别可靠的通道的封闭。
由于凹槽的底面宽度只稍大于孔口的直径,孔口断面对通道的可靠封闭也产生了有利的影响。
在本发明的特殊构成里,凹槽与条带本质上有互相对应的梯形断面,它们的底面是稍微弯曲的,它的外表面是弯曲成与软管圆周相适应的,因此,在静止状态下,条带实际上是完全填满了凹槽。
在凹槽内的径向孔口之间的距离是在1公分至3公分之间,而它们的直径则在大约3毫米至5毫米之间。通道的直径大约在5毫米至10毫米之间是合乎目的的,视灌浆材料而定。凹槽的深度是在大约2毫米至5毫米之间。而这也相当于条带在未受到压力状态时的厚度。尤其适于基体的材料是聚氯乙烯,适于条带的材料有泡沫橡胶,海棉状橡胶或氯丁橡胶。管状外套可为网孔大而不会变形的编织物。
本发明的其他目的、特征、优点以及应用可能性将出现在下面参阅附图针对实施例所作的说明里。这时,所有文字说明和/或图示的特征本身或以任何有意义的组合均构成本发明的主题,甚至与它们在权利要求书内的概括或者权利要求的引用无关。
图面说明:
图1a显示出本发明第一实施例的灌浆软管基体的立体图;
图1b显示出根据图1a中基体的沟状而螺旋环绕的凹槽内设置的条带的立体图;
图1c显示在将图1b的条带插入沟状而螺旋环绕的凹槽内后,图1a的基体的软管状外套的立体图;
图1d显示在组装图1a至图1b中的各零件后,呈现本发明第一实施例灌浆软管的剖面图;
图2显示出本发明另一实施方式,相似于图1d的剖面图;
图3显示出本发明的又另一实施方式,相应于图1d的剖面图。
灌浆软管1是由基体2构成,该基体2具有本质上为空心圆筒形的管壁,因而形成穿过的或者是中心的(图1a,1d以及3)、或者是偏心的轴向平行的圆筒形通道3。以后会硬化的灌注浆是从灌浆软管1的一端或两端被压入通道3内的,或视情况,在遇到设在两端之间的接头时也是从这里起压入的,以便于使得灌注浆遍布于混凝土结构中插入了灌浆软管1的施工缝全长度上,以使封闭该施工缝。按照图1a及图1d,在基体2的外壳表面4设有沟状而螺旋环绕的凹槽5,其延伸于基体2的全长。在凹槽5内分布有遍及凹槽全长的径向孔口6,以供灌浆从通道3流入欲封闭的施工缝内。在凹槽5内插入覆盖孔口6(图1b)的延长条带7。条带7是由例如氯丁橡胶等能在灌浆的内压力(灌注压力)下可被压缩的材料制成。为了将条带7保持于凹槽5里,以及使得灌浆软管1的横断面即使是在加压期间也不会扩大,基体2连同插入的条带7是紧紧地被可透过流体的管状外套8所包围。基于这种情况,唯一的凹槽5螺旋状环绕着基体,虽然只使用了唯一的条带7,在加压期间灌浆就能涌出,且实际上均匀地分布于灌浆软管1的整个圆周。外套8最好是以网孔大而不会变形的织物制成,以便紧紧地包围基体2的外壳表面4以及条带7的外表面9,以便使条带7甚至在受到高内压力(灌注压力)时也不会变形。织物的大网孔度保证了灌浆在加压期间能通行无阻地流遍灌浆软管1的整个圆周,而这时灌浆软管1也容许相反地来自外部的例如混凝土的压力加在条带7上,其结果是条带7就紧紧地被压入凹槽5内,可靠地将灌浆软管1从外部封闭,因此,不会使有害材料进入通道3里而阻塞它。因此,按照本发明的解决方案,具备了任何时候都能起到内部阀门装置的作用,并保证灌浆在灌注期间能均匀地分布于欲封闭的施工缝,而不会使灌浆软管的横断面扩大。
如果,如图2可看出,将通道3偏心地配置于圆筒形基体2内,则可以使灌浆软管1的横断面比较小,尽管条带7的厚度比较大,以形成良好的开关作用。这时,按照图2所涉及的灌浆软管1的实施方式,凹槽5与条带7是轴向平行于通道3延伸的,而凹槽5的开口角度α具有小于或大于90度(即90度左右)。
展示于图3的实施方式同样是凹槽5与条带7轴向平行于通道3而延伸的灌浆软管1,但是凹槽5的开口角度α大于90度,如此,就能达到在加压期间使灌浆非常均匀地分布于灌浆软管1的圆周。
所有图示的特殊构成的共同点是,凹槽5与条带7的侧边界面10都是互相从径向的外边倾斜到径向的内边。因此,凹槽5与条带7最佳构成本质上是互相对应的梯形断面。条带7或凹槽5的底面11是稍微弯曲的,而条带7的外表面9是对应于灌浆软管的圆周而弯曲的。同样,所有实施方式的共同点是;凹槽5的底面11的宽度只稍微大于径向孔口6的直径,因此,按照本发明的灌浆软管1的内部阀门装置在较低的灌注压力时已经打开了;但是,另一方面,当条带7受到来自外部的压力冲击时,又能保证可靠地封闭。凹槽的断面除了梯形之外,也当然可以是任何其他所需形状,只要适于容纳对应的可压缩条带,圆形塞绳之类的东西就可以。例如,可作成半圆,椭圆或其他类似的形状。
