The present invention relates to a process for preparing laminated veneer lumber treated with microfibrillated cellulose. The invention also relates to a modified laminated veneer lumber product produced using said process.

A fitting attachable to a cross-laminated panel provides a chase, plumbing space, airflow duct, or wiring route on an edge of the cross-laminated panel. The fitting may run between edges of multiple cross-laminated panels that contain integral hollow members, forming a customizable network of contiguous coplanar routing paths, accessible without installing pipes and wires behind, or in front of the cross-laminated panels. The fitting may also provide a vertical chase for single or multiple cross-laminated panels. The fitting takes advantage of one or more hollow members in the cross-laminated panels to provide contiguous routing paths for wires, pipes, and venting within the cross-laminated panels themselves, extending across any layout of multiple cross-laminated panels. The fitting may additionally serve as mechanical support for attachment of adjacent panels. Further, the fitting may provide structural connection for the CLT panels as required to meet structural code requirements for the building.

A method for producing an ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique includes: subjecting, while subjecting a solid wood to surface compression and enhancement, the solid wood to primary stabilization treatment by controlling a temperature of a hot pressing plate to obtain a compressed enhanced solid wood; putting the compressed enhanced solid wood into a heat treatment tank; and subjecting the compressed enhanced solid wood to secondary stabilization treatment by controlling a pressure and a temperature of steam or air in the heat treatment tank and a treatment time to obtain a finished product. The ultra-stable surface-compressed enhanced solid wood flooring produced by the method features high dimensional stability, low set-recovery after water absorption, and desired moisture and heat resistance.

The second layer of the cross-laminated panel having second boards oriented in a second direction, the second direction being substantially perpendicular to the first direction. The third layer of the cross-laminated panel having third boards oriented in the first direction. The cross-laminated panel also including adhesive situated between each of the first layer, the second layer, and the third layer. The cross-laminated panel further including a hollow member forming a conduit and disposed in any one of the first layer, the second layer, and the third layer.

This invention relates to a process for modifying wood. The process comprises treating the wood with an impregnating solution comprising an alkali metal (or alkaline earth metal) silicate, under conditions sufficient to impregnate the wood with one or more of the components of the impregnating solution. The process can comprise an optional second impregnation with a second impregnating solution. The process also comprises adding gaseous carbon dioxide to the treated wood, in the absence or presence of water, under pressure ranging from about 2 to about 12 bars, thereby lowering the pH of the treated wood to about 11 or below, to stabilize and/or fix the components of the impregnating solution in the wood. The process is green, non-toxic, and the resulting modified wood or wood product can be used across all primary construction and infrastructure applications.

A method of making treated laminated veneer lumber (LVL) according to one example of the present disclosure includes obtaining assembled LVL. The assembled LVL comprises a plurality of layers of veneer wood assembled together with adhesive. The LVL is loaded into a pressure chamber. A vacuum is created in the pressure chamber thereby removing air from the plurality of layers of veneer wood of the LVL. Inorganic solution is added into the pressure chamber. The pressure chamber is pressurized to force the inorganic solution into the wood creating the treated LVL.

A method of manufacturing engineered wood is provided, the method comprising: feeding wood through a processor while exposing the wood to compressive and tensile forces to produce naturally oriented strands of fibers; adding an adhesive to naturally oriented strands of fibers to provide adhesive covered strands; feeding the adhesive covered strands into a press; applying a first pressure to the adhesive covered strands to provide a pressed wood with a selected first dimension and a selected second dimension; and applying a second pressure normal to the first pressure to the pressed wood to provide an engineered wood having the selected first dimension, the selected second dimension and a selected third dimension and a selected density. An installation for manufacturing the engineered wood is also provided.

A durable palm fiber composite material is obtained by impregnating an unprocessed palm bark in a resin adhesive solution prepared by using a palm leaf as a raw material and then hot-pressing. The palm bark is dried under a natural state without additional processing. The palm leaf is made into a tannin resin adhesive solution under the effect of additives such as furfuryl alcohol, paraformaldehyde, and others. A pH value of the adhesive solution is controlled to be 9-11. A solid content is 40-60%. An adhesive amount applied to the palm bark by the resin adhesive solution is 800-1500 g/m.sup.2. Odd number of layers (three or more layers) of palm barks that are impregnated by the resin adhesive solution and are hot-pressed to the composite material. Hot-pressed parameters are as follows: the temperature is 150-180 C. the unit pressure is 0.8-1.5 MPa, and the time is 10-30 s/mm.

The third layer of the cross-laminated panel having third boards oriented in the first direction. The cross-laminated panel also including adhesive situated between each of the first layer, the second layer, and the third layer. The cross-laminated panel further including a hollow member forming a conduit and disposed in any one of the first layer, the second layer, and the third layer.

A cloud-based system network for verifying and documenting prefabricating Class-A fire-protected wood-framed buildings produced from a prefabricated Class-A fire-protected wood-framed building factory system supporting multiple production lines for producing Class-A fire-protected wood-framed components including wall panels, floor panels, stair panels, floor trusses, and roof trusses for use in constructing custom and pre-specified prefabricated Class-A fire-protected wood-framed buildings. The system network includes (i) a data center with web, application and database servers for supporting a web-based site for hosting digital images of barcoded/RFID-tagged certificates attached to prefabricated Class-A fire-protected wood-framed building components, and other certification documents, and (ii) mobile smart-phones used to capture digital photographs and video recordings of Class-A fire-protected wood-framed building sections, and upload the captured digital images to the data center, for each prefabricated wood-framed building project, so that building purchasers, insurance companies, builders, architects and other stakeholders can review such certifications and documentations during the prefabrication of wood-framed buildings from the factory system.
