Enhancement-type glue laminated wood member with toothed plate and preparation technology of enhancement-type glue laminated wood member

The invention discloses an enhancement-type glue laminated wood member with a toothed plate and a preparation technology of the enhancement-type glue laminated wood member. The glue laminated wood member comprises a layer plate, a metal toothed plate and an adhesive. When the glue laminated wood member is a wood beam, the member layer plate comprises a flat-connection lengthening layer plate at a pressed area at the upper portion of a neutral axis, a flat-connection lengthening layer plate with a joint enhanced through the metal toothed plate, a finger-connection lengthening layer plate at a pressed area at the lower portion of the neutral axis, and a finger-connection lengthening layer plate with a joint enhanced through the metal toothed plate. When the glue laminated wood member is a wood column, the member layer plate comprises an outer-layer finger-connection lengthening layer plate with a joint enhanced through the metal toothed plate and an inner-layer flat-connection lengthening layer plate with a joint enhanced through the metal toothed plate. According to the glue laminated wood member, adhesive layers are arranged between the layer plates and arranged between the layer plates and the metal toothed plate. According to the stress characteristic of the glue laminated wood member, on the basis that the flat-connection lengthening mode and the finger-connection lengthening mode are adopted in the inner-layer layer plate and the outer-layer layer plate respectively, the lengthening positions of the layer plates are enhanced through the metal toothed plate.
