    • The invention relates to a protective element (20) for connecting to a concrete element (10) of a tunnel lining, to the concrete element (10) and to the method for producing the concrete element (10). It is an object of the invention to provide a protective element (20) for a tunnel lining, or the associated concrete element, which ensures that the protective casing of the tunnel lining is better safeguarded against corrosive gases or liquids. The solution of the invention provides that the protective element (20) is produced from an injection-moldable plastics material, that a protective portion (21, 22, 23) is connected in a single piece to a seal (30), wherein the connection is gas-tight and liquid-tight, that the protective portion (21, 22, 23) is connected in a single piece to a connecting element (24, 25, 26, 27, 28), and that the single-piece connection is produced by injection molding of the plastics material.
    • 本发明涉及一种用于连接到混凝土构件(10)的隧道衬砌的混凝土构件(10)的保护元件(20)和用于生产混凝土构件(10)的方法。 本发明的一个目的是提供一种用于隧道衬砌或相关混凝土构件的保护元件(20),其确保隧道衬砌的保护外壳更好地防止腐蚀性气体或液体受到保护。 本发明的解决方案提供了保护元件(20)由可注射成型的塑料材料制成,保护部分(21,22,23)以单件连接到密封件(30),其中连接 保护部分(21,22,23)以单件连接到连接元件(24,25,26,27,28),并且单件连接是 通过塑料材料的注射成型制成。

    • The construction element (1) has a hollow body (2) which extends along a longitudinal axis (A) and has substantially rectangular cross-section, possibly with rounded corners, and at least a first (3a) and at least a second (3b) strut element, wherein the first strut element (3a) extends from a first edge of the hollow body (2) to the second edge which lies opposite it with respect to the longitudinal axis, and the second strut element (3b) extends along the other diagonal between the associated edges. The strut elements (3a, 3b) are advantageously designed and arranged such that they absorb compressive forces but not tensile forces. A semi-finished product (1a) which has the strut elements (3a, 3b) and a tubular sleeve element (4) which extends along a longitudinal axis (A) can be arranged inside the construction element (1). The hollow body (2) and the strut elements (3a, 3b) can be fabricated completely from a fiber-reinforced plastic. A surface element (5) is also shown which has a plurality of construction elements (1) according to the invention which are arranged next to one another and are arranged between two cover elements (6, 8) in a filling compound (7). Such surface elements (5) can, for example, be used as floor or roof elements, especially when particularly high bearing capacity to dead weight ratios are required. Methods for producing the construction elements (1) and the surface elements (5) are also proposed.
    • 结构元件(1)具有沿着纵向轴线(A)延伸的中空体(2),并且具有基本上矩形的横截面,可能具有圆角,并且至少第一(3a)和至少第二(3b) )支柱元件,其中所述第一支柱元件(3a)从所述中空本体(2)的第一边缘延伸到相对于所述纵向轴线与其相对置的第二边缘,并且所述第二支柱元件(3b)沿着 相关边缘之间的其他对角线。 支柱元件(3a,3b)有利地设计和布置成使得它们吸收压缩力而不是拉伸力。 具有沿纵轴线(A)延伸的支柱元件(3a,3b)和管状套筒元件(4)的半成品(1a)可布置在结构元件(1)的内部。 中空体(2)和支柱元件(3a,3b)可以完全由纤维增强塑料制成。 还示出了具有根据本发明的多个构造元件(1)的表面元件(5),它们彼此相邻布置并且布置在填充化合物(7)中的两个覆盖元件(6,8)之间。 例如,这样的表面元件(5)可以用作地板或屋顶元件,特别是当需要特别高的承重能力时。 还提出了用于生产结构元件(1)和表面元件(5)的方法。
