Wooden I joist beam for house building

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.

Advantages

I-Joist is an important part of the international common building formwork system. It has the characteristics of light weight, high strength, good straightness, not easy to deformation, water and acid and alkali resistance on the surface. It can be used year-round and has low cost amortization costs. Can be used with domestic and foreign professional template system products.

Can be widely used in horizontal formwork system, vertical formwork system (wall mold, column mold, hydraulic climbing mold, etc.), variable arc formwork system and heterosexual formwork and other formwork system.

Woodworking beam straight wall template for loading and unloading template, convenient assembly, in a certain range and degree can be assembled into a variety of sizes of templates, flexible application. Mold plate stiffness, length and height are very convenient, the maximum of a template can be poured more than 10 meters. Because of the light quality of the template material, the whole template is much lighter than the steel template when assembled.

The system product parts high degree of standardization, good reuse, meet the requirements of environmental protection.
