Patent ID: 8245470

Claim:
A wood concrete composite system ( 100 , 200 ) coupling wood and concrete, the system being a load bearing structural component and comprising: a wood construction component ( 110 , 111 , 112 , 210 , 211 ), an at least single intermediate layer ( 140 , 141 , 142 , 143 , 230 , 231 , 232 ), a concrete construction unit ( 150 , 151 , 152 , 240 , 241 ), and at least one laterally elongated connection device ( 130 , 220 , 223 ) formed of flat, thin metal having an array of holes/openings formed therein, the connection device supporting composite action between the wood construction component ( 110 , 111 , 112 , 210 , 211 ), and the concrete construction unit ( 150 , 151 , 152 , 240 , 241 ), which connection device is adhered to and embedded in laterally elongated openings of the wood construction component such that at least a portion of the array of holes/openings is located entirely within the laterally elongated openings, which connection device passes through the intermediate layer ( 140 , 141 , 142 , 143 , 230 , 231 , 232 ) and is embedded in the concrete construction unit, wherein at least one side of the concrete construction unit ( 150 , 151 , 152 , 240 , 241 ) faces towards the wood construction component ( 110 , 111 , 112 , 210 , 211 ), and the at least single intermediate layer ( 140 , 141 , 142 , 143 , 230 , 231 , 232 ) is interposed between the wood construction component and the concrete construction unit so as to prevent direct contact between the wood and concrete while allowing composite action therebetween, wherein further the connection device includes a forking at approximately its half-height.
