    • Paper-based elongate structures suitable for use as lumber substitutes, articles of manufacture made thereof, kits of materials including such structures, and machines and methods for making the same. Elongate structures according to the invention include a hollow outer portion formed of corrugated fiberboard sheet material and an accordion-folded inner support formed of corrugated fiberboard sheet material. The hollow outer portion has four outer surfaces that define a rectangle when viewed in cross-section transverse to a longitudinal axis of the elongate structure. The accordion- folded inner support is enclosed within the hollow outer portion. The inner support includes a plurality of first spaced-apart peaks that contact a first inner surface of the hollow outer portion and a plurality of second spaced-apart peaks that contact an opposing second inner surface of the hollow outer portion. The accordion-folded inner support structure improves the beam strength, crush resistance and lateral strength of the elongate structure.
    • 适合用作木材替代品的纸基细长结构,由其制成的制品,包括这种结构的材料套件,以及用于制造它们的机器和方法。 根据本发明的细长结构包括由瓦楞纤维板片材形成的中空外部部分和由瓦楞纤维板材料形成的折叠折叠的内部支撑件。 中空的外部部分具有四个外表面,当从与细长结构的纵向轴线横截的横截面观察时,该外表面限定了矩形。 手风琴折叠的内部支撑件封闭在中空的外部部分内。 内部支撑件包括接触中空外部部分的第一内表面的多个第一间隔开的峰和接触中空外部部分的相对的第二内表面的多个第二间隔开的峰。 手风琴折叠的内部支撑结构提高了细长结构的光束强度,抗压缩性和横向强度。
