Building construction structure manufacturing method, involves applying composition to face of one of walls before connecting walls, where composition is flown and hardened after application, and forms thermal insulation layer between walls

摘要

The method involves manufacturing two walls (2, 3) of a construction structure (1) by molding of a setting compound e.g. concrete. The walls are connected by connection devices e.g. rods, extending between faces (2a, 3a) of the respective walls, such that the faces are opposite to one another. A composition e.g. polyurethane based expansive foam, is applied to the face of one of the walls before connecting the walls by pouring the composition in a formwork (11), where the composition is flown and hardened after its application, and forms a thermal insulation layer between the walls. The formwork is made of fireproof and thermally insulating material such as rock wool. An independent claim is also included for a support for connection devices.
