    • An object extends into a passage and defines a clearance space with the inner wall of the passage. A hardenable, foamable synthetic resin in flowable state is admitted into the clearance space. Upon hardening and foaming of the synthetic resin, the object is sealingly secured in the passage by the synthetic resin. In a preferred application, the passage is one provided in a coal mine and the object is a hose line for the purpose of suppressing dust. The synthetic resin is advantageously polyurethane including a polyhydroxyl component which contains a polyetherglycol having a hydroxyl number of 300 to 350 and a polyetherglycol having a hydroxyl number of 450 to 500. The polyetherglycol components respectively constitute 80 to 90 parts and 10 to 20 parts of the polyhydroxyl component. The polyhydroxyl component preferably includes a filler in an amount such that the weight of the latter at least equals that of the polyhydroxyl component.
    • 物体延伸到通道中并且与通道的内壁限定间隙空间。 可流动状态的可发泡的可发泡合成树脂进入间隙空间。 在合成树脂硬化和起泡时,物体通过合成树脂密封地固定在通道中。 在优选的应用中,通道是设置在煤矿中的物体,并且该物体是用于抑制灰尘的软管线。 合成树脂有利地是聚氨酯,其包含含羟基数为300至350的聚醚二醇和羟基数为450至500的聚醚二醇的多羟基组分。聚醚二醇组分分别构成80至90份和10至20份 多羟基成分。 多羟基组分优选包括一定量的填料,使得后者的重量至少等于多羟基组分的重量。

    • The invention relates to a plastic screw plug (6) for attaching a rail to a sleeper, in particular concrete sleeper, having an essentially cylindrical plug body which has at the head end a stem region (7) which preferably adjoins a plug crown (8) toward the bottom, and in the continuation of which stem region (7) has an outer thread (9) with which it can be turned out of or into the sleeper, and is provided with an inner thread (10) underneath the stem region (7) in order to receive a sleeper screw. The intention is to improve such a plastic screw plug, in particular, with regard to its operating properties such as uniform application of force into the sleeper, simpler mounting and replaceability, reduction of the risk of fracturing, and additionally to permit it to be used in a variable way. For this purpose, the stem region (7) has on the inside, in the junction with the inner thread (10), a shoulder (13) which reduces the internal diameter over part of the length of the stem region (7) and extends in a spiral shape over at least part of the circumference.
    • 本发明涉及一种用于将轨道连接到轨枕,特别是混凝土轨枕的塑料螺栓(6),其具有基本上圆柱形的塞体,头部具有杆部区域(7),杆部区域优选地邻接塞子冠部(8) ),并且在所述杆区域(7)的延续中具有外螺纹(9),所述外螺纹(9)可以被转动到所述轨枕中或者进入所述轨枕,并且在所述杆部区域下方设置有内螺纹(10) (7),以便接收卧铺螺丝。 其目的是改进这种塑料螺塞,特别是关于其操作性能,例如将力均匀地施加到卧铺中,更简单的安装和更换性,降低压裂的风险,并且还允许使用它 以可变的方式。 为此目的,杆区域(7)在内部与内螺纹(10)的接合处具有肩部(13),该肩部(13)减小了杆部区域(7)长度部分的内径并且延伸 在圆周的至少一部分上呈螺旋状。
