Wood composite structure combined with interior and exterior beams {LAMINATED TIMBER STRUCTURE COMBINED WITH INTERIOR AND EXTERIOR BEAM}

The present invention relates to a timber aggregated structure combined with an interior and exterior beam, and more particularly, an interior and exterior beam capable of reinforcing the strength of a steel beam and reinforcing flame resistance, acting to emit phytoncide, and enhancing the aesthetic aesthetics visible externally. It relates to a wood composite structure combined with.

In general, a plate is made of a plate-shaped wood whose thickness is less than 8 cm and the width is three times or more than the thickness when making the necessary wood by processing solid wood. These boards use solid wood as it is, and there are laminated boards, plywood, MDF, particle boards, etc. that are made by processing for the purpose of making large and wide boards without the disadvantages of solid wood.

In particular, in order to utilize limited natural resources without wasting, a board manufactured using a method of attaching narrow or short trees is called a stacking board (or a stacking board). These bonded plates are divided into solid and finger joints according to the bonding method, and the finger joints can be divided into a top finger joint in which the bonding surface is visible from above, and a side finger joint in which the bonding surface is not visible. I can. In addition, the purpose of each furniture or accessories is also important, but for small items or furniture where the appearance is not important, a finger-joint type gluing plate is used, which is relatively inexpensive, and when making furniture or accessories whose appearance is important or bulky, the solid method I am using the assembly board of.

The built-in beam combined with the cross-aggregating material 100 may provide stiffness against external force. Built-in beam refers to a structural rolled steel made by rolling so that the shape of the cross section is uniform, and is classified into circular beams, I beams, T beams, L beams, D beams, H beams, square beams, or c beams, depending on the shape of the fragment. Can be. The H-beam consists of a wide, thick flange and a relatively thin web. Beams are divided into ordinary steel and special steel according to their characteristics, and are heated at 1150℃ to 1300℃ and 1050℃ to 1200℃ respectively in semi-finished products manufactured through steelmaking work: Beam Blank, Bloom and Billet And then hot-rolled into a specific cross-sectional shape.

For example, mechanical drying used to produce the first and second stacking plates 111 and 121 may use a steam method, a hot air method, a smoking method, a vacuum method, or a high frequency drying method. For example, the molder may be a 6-axis molder, and the surface of the dried wood may be molded using the molder to produce the first collecting plates 111 and the second collecting plates 121. For another example, in the fifth step of treating the surface of wood, the surface of wood may be coated with a flame-resistant and incombustible coating material.

In one embodiment, the laminated plates may be stacked with each other in the direction of the wood fibers parallel to form a wood laminated structure. In one embodiment, the laminated plates may be laminated regardless of the direction of the wood fibers to form a wood laminated structure.
