Patent CA-2153631-A1 (CA)
Title: Method and apparatus for constructing prestressed structures utilizing a membrane and floating dome assembly
Inventor: DYKMANS MAXIMILLIAN J
IPC: E04G11/04
Filed: 1995-07-11
Abstract: The present invention is directed to improved tank or containment vessels and processes and apparatus for their construction.   The tanks or containment vessels usually consist of circular walls resting on a base and a dome supported by the walls.   The dome of the subject pre-stressed tank is formed by deploying or creating a mem-brane on the base, applying one or more layers of rigidi-fying material (and prestressing or reinforcing material if needed) on the membrane and then forming said membrane into a dome before the rigidifying material sets by the selective introduction of compressed air at appropriate locations between the base and the membrane.  The harden-ing of the rigidifying material results in a composite preformed rigid roof or dome having a membrane liner and an overlay of composite construction.  Once the walls are created,  air pressure can be further utilized to raise this preformed composite dome upward to a predetermined height after which it is fastened to the walls.  An appro-priate air seal may be used to prevent excessive leakage of air between the walls and the dome and to assist in the raising of the dome.  Utilizing this air cushion procedure to raise the dome to its proper location, eliminates the need of scaffolding and other costly support structures. Integral seismic anchors may be also used to complete the construction process  to protect  the  structure against earthquakes and other tremors by anchoring the dome to the tank walls and the tank walls to the base in a manner whereby the seismic forces are translated parallel to the wall instead of radially to the wall.
