Fiber-reinforced post-tensioned concrete slab with openings
The present invention relates to a concrete slab comprising conventional concrete and a combined reinforcement of post-tensioned steel strands having a diameter ranging from 5 mm to 20 mm and a tensile strength higher than 1700 MPa, and fibers being steel fibers and used in an amount ranging from 5 kg/m3 to 90 kg/m3, or being coarse synthetic fibers and used in an amount ranging from 1.5 kg/m3 to 9.0 kg/m3, characterized in that the post-tensioned steel strands have a diameter ranging from 5 mm to 20 mm and a tensile strength higher than 1700 MPa, and the fibers are steel fibers and used in an amount ranging from 1.5 kg/m3 to 9.0 kg/m3. Wherein the plate has an upper surface, a lower surface and side surfaces, further, each strand or set of strands has two ends, further, each strand or set of strands is provided with an end anchor on at least one of its ends, and wherein the plate has at least one opening in its upper surface, the anchor is configured such that the anchor is accessible from the upper surface through the opening.
本发明涉及一种混凝土板，该板包含常规混凝土以及后张钢绞线和纤维的组合增强件，所述后张钢绞线的直径范围为5毫米至20毫米，抗拉强度高于1700MPa，所述纤维是钢纤维并且用量范围为5kg/m3至90kg/m3，或者是粗合成纤维并且用量范围为1.5kg/m3至9.0kg/m3，其中板具有上表面、下表面和侧面，进一步地，每根绞线或一组绞线具有两个端部，进一步地，每根绞线或一组绞线在其至少一个端部上设置有端部锚固件，其中，板在其上表面中具有至少一个开口，使得可通过所述开口从所述上表面接近所述锚固件。
