Title: Plastics sheet lining for concrete has anchor ribs - with two beading strips giving dovetail type fixing
Inventor: KOPS FRIEDRICH DIPL ING
IPC: E04B1/66
Filed: 1975-12-19
Abstract: An internal or external lining for concrete structures, e.g. for internally lining pipes, comprises a flexible, extruded plastics sheet, e.g. of plasticized PVC, EPDM or polyethylene or mixed substances. The sheet has ribs or webs extending from one side in parallel rows to anchor it in the concrete. The webs each consist of a rib and a pair of round-section wires one on each side at the end of the rib, forming a notch or depression between them along its summit. Pref., the depth of penetration of the wbs is at max. one half the concrete cover to the reinforcement. Each individual sheet of the material pref. has an edge equal in width to the spacing between the webs. the clear spacing (b) between webs (2) is pref. at least twice the maximum aggregate size in the concrete. Used in particular for lining under ground sewage or similar pipes whichmsut be protected against aggression and corrosion and at the same time may be surrounded by ground water. Gas which builds up behind the plastic lining within the concrete and which cannot escape due to the ground water has a tendency to push the lining off. The arrangement of ribs shown provides an excellent retaining action preventing this from happening.
