One or more collars are configured to center a rod within a drilled hole in glued-in-rod (GIR) structures. The one or more collars fit over an end and/or along a length of the rod that gets inserted first into the drilled hole. The one or more collars may include splines or other features extending from a base of the collar. The features contact walls of the drilled hole to center the rod in the hole, while at the same time allowing fluid such as glue to pass around the collar as the collar and rod are inserted into the hole.

A bamboo laminated lumber is provided having structural characteristics meeting or exceeding dimensionally equivalent wood based components. The bamboo laminated lumber is formed from bamboo laminated elements laminated and joined together to form dimensional lumber and engineered lumber components. The bamboo laminated lumber element comprises a combination of linear bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain aligned and skewed bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain offset from centerline at a specified angle. Top and bottom linear bamboo starter boards are laminated to a central skewed bamboo starter board yielding a bamboo laminated lumber element.

A method for making modular armrest includes the steps of providing at least fourteen blank wood pieces, arranging the blank wood pieces in juxtaposed relationship, bonding the arranged blank wood pieces to obtain a bonded blank assembly, and marking four sawlines to divide a front surface of the bonded blank assembly into five trapezoid zones, the middle tree of which has the same surface area. Among the three middle trapezoid zones, the inbetween is an inverted form of each of the flank ones such that the inbetween corresponds to a widthwise profile of the modular armrest while each of the flank ones corresponds to an inverted form of the widthwise profile.

The invention is directed to an insert system comprising an insert with a base and an outer skirt extending from the base, thereby forming a chamber. The outer skirt is provided with a first inner skirt surface and a first outer skirt surface. The insert system further comprises a panel with a core structure and a first cover sheet that at least partially covers the core structure. The first cover sheet defines a first outer panel surface and has an opening. At least one piston is arranged in the opening and beneath the first outer panel surface. According to the invention the piston during mounting of the insert sweeps into the chamber to discharge an adhesive agent from the chamber into the core structure via at least one pathway.

A method of manufacturing glue laminated timber columns involves forming a glue laminated timber panel and then cutting the glue laminated timber panel into a selected number of glue laminated timber columns. The method provides a substantial saving compared to a custom mass timber column.

The present invention relates to a method for shaping a frame structure using a multilayer board to solve the technical problem of low production efficiency of the existing bamboo frame structure. The present invention has the first solution of bending a multilayer board into a profiled board using the board bending technology; cutting the profiled board into several framing units; and finally connecting end portions of one, two or plural framing units one another, thereby forming a frame structure. The present invention has the second solution of gluing and stacking a plurality of single boards and laminating them into a profiled board; cutting the profiled board into several framing units; and finally connecting end portions of one, two or plural framing units one another, thereby forming a frame structure.

The present invention relates to a structural joint for attaching two boards by their butts, achieving the correct transmission of forces between them by means of a staggered configuration of the butts thereof to increase the contact surface between both boards, allowing the mutual coupling thereof, both being aligned and coplanar, and at least one of the steps of both boards having a finger profile to further increase the contact surface between both boards.

A system and method for producing a rectangular wooden panel with boards extending diagonally at an angle (), where each of the boards has opposite longitudinal sides and transverse sides includes a trimming device for trimming the transverse sides of the boards at an angle (90). The trimmed boards are transported to a position in front a joining station, and the boards are arranged at angle () in relation to a direction of displacement. The boards are then glued on at least the longitudinal side facing a board already located in the joining station, and then inserted into the joining station with a displacement device that includes a plurality of towing trolleys arranged on a coupling bar. The displacement device travels a displacement path in the displacement direction that runs parallel to the orientation of the transverse sides of the boards. The inserted board is pressed and glued to the board already in the joining station. These steps are repeated until a wooden panel of the desired size is achieved. Then, a triangular gusset is made with a cut running perpendicular to the transverse sides at one end of the wooden panel to produce a first right-angled side edge, and this cut-off gusset is then glued at the opposite end of the wooden panel such that a second right-angled side edge is produced. The system includes a controller which controls the cutting, gluing, pressing, joining, and displacement operations.

This invention relates to a process for the division of an individual input source log into discrete longitudinal lengths for subsequent processing. The process comprises receiving an individual input source log, dividing the input source log into one or a plurality of output log portions of a predetermined length, wherein at least a portion of said output log portions resultant from said division are of a substantially equal or substantially constant or consistent longitudinal length, and wherein said substantially equal or substantially constant or consistent longitudinal length output log portions are procured as a feed stream of log material for a subsequent processing step. This process provides for the processing of logs and subsequent assembly into an end product formed from a composite of sticks derived from said processed logs.

A device for joining multi-layered panels made of individual boards has a height-adjustable workbench. layers of boards arranged at an angle to each other and joined together. A guide for the material is provided at least on one side of the workbench, preferably on two adjoining sides. The device comprises at least one transport device for transporting boards to the processing position.
