Wood-concrete-composite systems

Abstract

A wood concrete composite system (100,200) has a wood construction component (110, 111, 112, 210, 211), at least single intermediate layer (140, 141, 142, 143, 230, 231, 232) and a concrete construction unit (150, 151, 152, 240, 241). The concrete construction unit (150, 151, 152, 240, 241) faces at least with one side towards the wood construction component (110, 111, 112, 210, 211). The at least single intermediate layer (140, 141, 142, 143, 230, 231, 232) creates at least a partial uncoupling between the wood and concrete.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to wood concrete composite system, which includes at least one wooden specimen, and a concrete specimen. [0002] The patent DE 44 06 433 C2, the content of which is incorporated herein by reference, presents wood with inserted bonded shaped parts to connect with materials of any kind. The known connection system is a flat body in form of a steel sheet, which is bonded partially into a wooden specimen and partially reaches out of the wooden specimen. The exposed section of the connection system serves to connect to further material. [0003] From the disclosure writing DE 198 08 208 A1, the content of which is incorporated herein by reference, it is known to connect wood to concrete by glued in shaped parts. The known wood concrete composite connection includes flat bodies in form of a steel sheet, which are bonded with one end into a slot brought into the wood and reaches over the wooden surface with the other end. The exposed e...

Benefits of technology

[0012] To the surprise of the inventors, it was detected that the composite action can even be increased by connecting two ends of the connection device into the wooden component. It shows both an increase of the individual stability of the connection device itself and also an increase of the overall composite action.

Problems solved by technology

This uncoupling does however not reduce the composite action between wood and concrete substantially, since otherwise an economical solution is not to be obtained.
