Abstract

The invention discloses a pressing die and a method of a C-shaped wooden structural material with the high strength-weight ratio. The pressing die comprises a base, a core rod, clamps, pressurizing blocks, wedge blocks and pressure releasing blocks, wherein the base is of a groove-shaped structure with a U-shaped section, the base is composed of a bottom plate and side walls located on the two sides of the bottom plate, a groove is formed in the bottom plate, the groove is used for placing the core rod and the C-shaped wooden structural material, the core rod is used for wrapping the C-shapedwooden structural material around the outer wall of the core rod, the clamps are used for pressing C-shaped material flanges and curled edges of the C-shaped wooden structural material, a plurality ofpressurizing holes are formed in the joint between the left clamp and the right clamp, the pressurizing blocks are block bodies which are matched with the pressurizing holes and are detachably placedin the pressurizing holes, the two wedge blocks are arranged between the side wall of one of the two sides of the base and the left clamp and the side wall of the other one of the two sides of the base and the right clamp correspondingly, and the plurality of pressure releasing blocks are used for pressurized unloading of the wedge blocks and detaching the die. According to the pressing die and the method, the C-shaped wooden structural material with low cost can be quickly manufactured.

Description

technical field [0001] The invention belongs to the field of structural materials in the wood processing industry, and in particular relates to a pressing mold for C-shaped wooden structural materials and a preparation method for C-shaped wooden structural materials. Background technique [0002] In the field of wooden structural materials, the main structural materials are wood or structural panels of different sizes, and there is still a lack of a space-shaped structural material with relatively high strength and weight. Develop a new type of wooden structural material to provide a cost-effective wooden structural material for the construction industry. The Chinese patent CN106193297A previously applied by the applicant discloses a C-shaped wooden structural material for construction, which is made of wooden veneers through different assembly structures, sizing and molding. Its advantage is that the C-shaped wooden thin-walled structural timber can replace part of the stu...
