Introduction of solid wood laminated timber, is log laminated timber the same as solid wood laminate

Laminated timber, also known as finger jointed board, finger joint material or integrated board, solid wood laminated timber refers to the narrow and short wood strips are connected with adhesive (some boards are toothed connections), and then transversely widened, sanded on the upper and lower sides of the board. The process of solid wood laminated timber is basically the same as that of solid wood wide panel, but because the material specifications are smaller, there are many splices in the length direction. That is, the board that has been spliced into small pieces of solid wood after deep processing like "finger heads", because the sawtooth interface is used between the boards, similar to the cross docking of the fingers of the two hands, so it is called the finger joint board.

Because the logs are cross-combined, the combined structure itself has a certain binding force, and because there is no need to stick the surface board up and down, the glue used is extremely small.

Laminated timber:Also known as glulam wood, it is also known as finger jointing because of its shape similar to the shape of finger crossing, which can be directly painted with wood wax oil to prevent deformation.

Usage:Cabinets, tables, partition walls, large-format components such as table panels, cabinet side panels, top and bottom panels, cabinet partitions, bottom plates and drawer bottom plates and other non-exposed parts and drawer panels, side panels, bottom plates, cabinet doors and other small-format parts, etc.;

Advantages of laminated timber:Computer numerical control drying technology, uniform moisture content, not easy to mold, high flatness, more beautiful and healthier, in the sales of consumers more directly feel the environmental protection of the product.

Laminated timber classification:

1.According to the use environment: laminated timber can be divided into indoor laminated timber and outdoor laminated timber.

Indoor laminated lumber can be used in a dry indoor state, and as long as it meets the durability of the indoor use environment, it can meet the user's requirements. Laminated timber for outdoor use is often exposed to rain, snow and sunlight.

2.According to the shape of the product: laminated lumber can be divided into sheet laminated lumber, straight laminated lumber and curved laminated lumber. It is also possible to make laminated lumber into special-shaped sections, such as I-section laminated lumber and box-shaped cross-section laminated lumber or hollow cross-section laminated lumber.

3.According to the load-bearing situation: laminated timber can be divided into laminated timber for structural and non-structural laminated timber. Laminated timber for structures is a load-bearing member, which requires laminated timber to have sufficient strength and stiffness. Laminated timber for non-structural use is a non-load-bearing component, which requires the laminated timber to have a beautiful appearance.

4.According to the use, laminated timber can be divided into: non-structural laminated lumber; laminated timber for structures; laminated lumber for veneered non-structural use; Laminated timber for veneer structures. Laminated timber does not change the structure and characteristics of wood, it is still a natural substrate like wood.

It is not the same, the laminated timber is not the bottom plate and the large core board is the core board board, relatively speaking, it can not be said that it is good, depending on the field you use, commonly known as the large core board, which is the most basic material for decoration, which is made of two pieces of veneer in the middle of the sticky splicing board. **Slightly cheaper than a splint.

Advantages: simple processing technology, good nail holding force.

Disadvantages: Due to the combination of a variety of miscellaneous trees, the density difference is large, and it is easy to deform; High moisture content; high formaldehyde content; It cannot be used directly, it must be post-processed.

Features of the integrated board:

First, environmental protection: the integrated board materials are all high-quality wood, the main process is drying, finger jointing, and the amount of glue is only seven-tenths of other woodworking boards, which is an environmentally friendly product.

Second, practical: there are many kinds of integrated board specifications, and the thickness can be used separately when making furniture, which is both beautiful and cost-saving, and suitable for various decorations.

Third, beautiful: the integrated board is a pure natural board, natural and generous, and the wood grain is clear.

Fourth, economical: the surface of the integrated board is sanded and fixed, smooth and smooth, and the surface does not need to be pasted with a panel when making furniture, which is economical.

Fifth, stability: the integrated plate is degreased at high temperature and assembled by mortise and tenon; Durable, not deformed, very stable and very good.

(1) Laminated timber is manufactured from the short material of solid wood into the required size and shape, so that the small timber is used for large use, and the inferior timber is used for better use (2) The laminated timber material is used to remove wood defects such as knots and decay before gluing, so that the material with fewer defects can be manufactured. When paneling, wood defects can be dispersed even if they are still present. (3) Laminated timber retains the material sense of natural wood and has a beautiful appearance.

4) The raw materials of laminated timber are fully dried, and the moisture content of each part of laminated timber is still uniform even if it is large-section and long-sized timber, and the cracking and deformation are small compared with solid timber. (5) It is superior to solid wood in terms of physical and mechanical properties such as tensile and compressive resistance and material quality homogenization, and can be configured according to the strength of the laminate to improve its strength performance, and its strength performance is times that of solid wood. (6) According to the need, the laminated lumber can be manufactured into straight shapes and curved shapes.

According to the requirements of the corresponding strength, it can be manufactured into a gradual structure along the length of the section, and can also be manufactured into I-shaped, hollow square and other cross-sectional laminated lumber. (7) Laminated lumber made into curved shapes is an ideal material for timber structural components. (8) Before gluing, the plate can be treated with medicine in advance, even if the material is long and large, there can be enough medicine inside, so that the material has excellent anti-corrosion, fire resistance and insect resistance.

9) Due to the different uses, the laminated lumber is required to have sufficient gluing performance and durability, for which the laminated timber processing needs to have good technology, equipment and good quality management and product inspection. (10) Compared with solid wood, the yield of laminated timber is low, and the cost of the product is high.

Advantages: Because there are fewer connections of solid wood joints, the amount of glue used is also less, so the environmental protection coefficient is relatively high. It is easy to process and can be cut, drilled, sawed and formed.

Disadvantages: Solid wood finger jointing board is easy to deform and crack. Good solid wood finger jointing board is of high quality, but the cost is higher.

In the furniture industry, it is mainly used as large-format components such as furniture panels, door panels and side panels, cabinet partitions, house panels and drawer floors and other non-exposed components; Drawer panels, side panels, cabinet doors and other small format parts and chair supports, armrests, backrests, sofas, coffee tables and other curved parts. In the decoration industry, it is mainly used for stair side panels, steppers, floor and wall decorative panels, etc.

In terms of product structure, there are three main types of fir laminated timber (scarring) without tree knots (scars), double-sided knots without tree knots, and tree knots (1) According to the bearing situation, it can be divided into: structural laminated timber and non-structural laminated timber; (2) According to the shape of the product, it is divided into: straight laminated lumber, curved laminated lumber, square cross-section laminated lumber, rectangular cross-section laminated lumber and deformed cross-section laminated lumber; (3) According to the use, it is divided into:

laminated timber for structure, laminated timber for non-structure, laminated timber for veneer, laminated timber for veneer structure; (4) According to the laminate bonding method, it is divided into: finger-jointed laminates and flat-jointed laminated lumber; (5) According to the grade of laminated timber laminate, it is divided into: laminated timber of the same grade and laminated timber of different grades; (6) According to the grade of laminated timber laminate or tree species configuration, it is divided into:

Symmetrical structure (balanced composite structure) laminated timber, asymmetrical structure (non-balanced composite structure) laminated timber; (7) According to the force characteristics, it is divided into: horizontal laminated lumber, vertical laminated timber and axial load laminated lumber. 4. The general production process of laminated timber log timber - drying - sawing and planing - opening the vertebrae - gluing - pressure gluing - planing - gluing - surface spelling - planing - vertical and horizontal sawing - quality inspection - finished product identification and packaging.

Laminated timber is glued laminated timber (glulam for short), which is one of the three main engineering timber products together with wooden I-beams and veneer laminated timber. The laminated timber is also solid wood, sometimes called finger joints, which can be painted with wood wax oil to prevent deformation.
