I-Joist is a New Wooden Engineering Structural Component . It refers to the solid wood or LVL used as the upper and lower flange, and the plywood structural plate bonding, specifications and performance of stable bearing structural members.The I joist is made up of two main parts: Flange and web these two parts: the first part is the flange flange of the upper and lower Flange, which is made up of solid wood or LVL.The second part is the intermediate Web called the Web(net), the usual material is OSB board.The Flange gets its name from web and flange, which are connected together with high-quality adhesives to form an ‘I’ shape.The web of I joist can be cut open to accommodate wires and pipes. A common I-beam web will have 40mm pre-punched holes. The specific position and maximum size of the holes can be calculated according to the drawings and corresponding tables, as shown in Figure 2, and the strength of the I-beam will not be affected by the pipe cutting holes.
Low cost, high stiffness, light weight;
Exchangeable, achieve E0 environmental protection standard;
High degree of standardization system production components, reusable good.
