Product Description

Plywood is one of the indispensable man-made boards in the production of modern wood products, construction, packaging industries and vehicle and ship manufacturing. The industrial production of plywood meets the needs of saving and efficient use of wood. The industry has developed rapidly.

 

The development of structural plywood products not only adapts to the status quo of changes in the quality of wood raw materials, but also makes full use of low-quality wood, short wood and artificial industrial raw material forest resources to improve wood utilization.

 

The development of the plywood industry is inseparable from the research of advanced technology and equipment. After years of research and exploration, no matter the veneer rotary cutting of wood segments, the veneer cutting technology of wood squares, or the research of environmental protection adhesives, gratifying achievements have been made. results.

 

Plywood can be used for interior decoration of doors and windows, and in furniture production, it can be used as the panel and back panel of tables and cabinets; high-density fiberboard is widely used as laminate floor substrate; medium-density fiberboard is used for furniture panels and side panels; particleboard is used for interior Wall panels, furniture panels, etc.

 

To produce efficient structural members, the members must be joined with a high-resistance adhesive that can replace the joints typically made of steel members and screws.

 

Structural glulam has high strength properties, its static bending strength is about 23% higher than that of wood, and its static bending elastic modulus is about 22% higher. This is because some natural defects of wood, such as knots, decay, etc., are removed during the manufacturing process or the concentrated material defects are reasonably dispersed, which improves the non-uniformity of wood strength.

 

1.  The glulam structure is divided into two types: the plywood structure and the orthogonal glulam structure. Laminated glulam structures are mainly suitable for single- or multi-storey wooden structures with large spans and large spaces. Orthogonal glulam structures are mainly suitable for floor and roof structures, or single- or multi-layer box-type wood structure buildings composed of orthogonal glulam.
2. The fiber direction of each ply of the plywood component should be consistent with the length of the component. The number of laminate layers in the section of the laminated glulam component shall not be less than 4 layers.
3.  The directions of the fibers between the layers of the orthogonal glulam components should be stacked and orthogonal to each other. The number of layers of the cross-section should not be less than 3 layers, and it is not suitable for more than 9 layers, and the total thickness should not be greater than 500mm.
4. When designing the laminated glulam components and orthogonal glulam components, the requirements for structural glue should be indicated according to the use environment, and the component manufacturers should strictly follow the design requirements for production.
5. The design and construction requirements of the laminate-laminated timber structure should comply with the relevant requirements of the current national standard "Technical Specifications for Glued-Laminated Timber Structures" GB/T50708.
6. The production requirements of the laminated wood structure should comply with the relevant provisions of the current national standard "Technical Specification for Glued Wood Structure" GB/T50708 and "Glulam for Structural Use" GB/T26899.
7. The thickness t of the laminate is: 15mm≤t≤45mm; the size of the boards used for making cross-laminated wood should meet the following requirements: the width b of the laminate is: 80mm≤b≤250mm.
8. Orthogonal glulam should be composed of boards of the same length and thickness of the same layer. The board can be lengthened with finger joints, and the strength of the finger joints should meet one of the following requirements: f t,j,k≥5+f tk m,j,k≥8+ f tk where; f t,j,k --Standard value of tensile strength of finger joints (N/mm2); f m,j,k--standard value of flexural strength in width direction of finger joints (N/mm2); f tk--standard of tensile strength of template value (N/mm2).
9. Orthogonal glulam components can be used for floor panels, roof panels and wall panels, and the design of the components shall comply with the relevant provisions of Appendix G of this code.
10. The length direction of the outer layer of orthogonal glulam should be arranged along the grain, and two layers of wood can be arranged along the grain as the outer layer. When required by the design, the cross-grain laminate can also be used in a two-ply plank configuration.
11. Orthogonal glulam components can be connected by finger joints, and should meet the following requirements: when the components are finger-joined, the laminates of the cross-sections at both ends of the components at the finger joints should be arranged in the same way, and the grain direction of the components should be consistent accordingly; The finger joint length of the finger joint should not be less than 45mm.
12. When the cross-laminated wood components are connected by finger joints, the strength of the finger joint joints shall be determined according to the following regulations: when the strength verification experiment at the finger joint joints of the components is carried out according to the relevant national experimental standards, the strength of the joints shall be determined. The standard value of flexural strength shall not be lower than the standard value of flexural strength of finger-jointed members required by the design; when the strength verification experiment at the finger-jointed joints of the members is not carried out, the design values of the flexural strength and tensile strength of the finger-jointed joints of the members shall be It can be taken as 67% of the value of the fingerless member, and the design value of the compressive strength is the same as that of the fingerless member.
13. When the cross-laminated wood is glued, the surface of the board is smooth, free of dust, impurities, pollutants and other exuding substances that affect the bonding. After gluing, the laminate should be glued under pressure within the time specified by the adhesive used, and the glued surface should not be contaminated before gluing.
14. The splicing surface between the outer parallel grain boards of the same layer with orthogonal glue is suitable for gluing with adhesive. Splicing can be adopted for the splicing surface between the inner side grain wood board of the same layer and the horizontal grain wood board of the same layer. However, the splicing gap should not be greater than 6mm.
15. The adhesive used in cross-laminated wood should meet the requirements of strength and durability, and the type and performance requirements of the adhesive should comply with the relevant provisions of the current national standard "Technical Specifications for Glued Wood Structures" GB/T26899.
