Abstract: A reinforcement structure for reinforced-concrete buildings, comprises a servicing portion which can be dismantled and a fixed structural portion which shall remain embedded in the concrete casting and consists of an iron latticework which is also intended to support the servicing portion. The servicing portion comprises spacer elements and sidewall elements having stiffening reinforcements and members and elements are provided to releasably latching the spacer elements and the sidewall elements to the latticework framing. Such a reinforcement structure also makes possible a novel building method.
