Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a lightweight building plywood. Background Art

[0002] Plywood is the secondary processing of wood. The log is cut into thin veneer boards by a machine, and then glued together with glue to form plywood. Plywood is a sheet material made of three or more layers of veneer cut from wood segments or thin wood planed from wood squares, and then glued together with adhesives. Usually, an odd number of veneer layers are used, and the fiber directions of adjacent veneer layers are glued perpendicular to each other; the characteristics of plywood are uniform and the shape is stable. Generally, plywood must follow two basic principles in structure: one is symmetry; the other is that the fibers of adjacent veneer layers are perpendicular to each other. The symmetry principle requires that the veneer on both sides of the symmetry center plane of the plywood, regardless of the wood properties, veneer thickness, number of layers, fiber direction, moisture content, etc., should be symmetrical to each other. In the same plywood, veneer of a single tree species and thickness can be used, or veneer of different tree species and thickness can be used; but the tree species and thickness of any two layers of symmetrical veneer on both sides of the symmetry center plane should be the same. Plywood usually uses an odd number of veneer layers, and the fiber directions of adjacent veneer layers are glued perpendicular to each other. Commonly used ones include three-ply board, five-ply board, etc. It can improve the utilization rate of wood and is also a main way to save wood.

[0003] Adhesive bonding is a process method that uses the mechanical bonding force, physical adsorption force, and chemical bonding force generated by the adhesive on the bonding surface to connect two bonded parts. Adhesive bonding is applicable not only to the same material but also to dissimilar materials. The adhesive bonding process is simple, does not require complex process equipment, and the adhesive bonding operation does not need to be carried out under high temperature and high pressure. Therefore, the bonded parts are not easily deformed, and the stress distribution at the joint is uniform. Under normal circumstances, the adhesive bonding joint has good sealing performance, electrical insulation performance, and corrosion resistance.

[0004] At present, most plywood is spliced and installed by adhesive bonding. However, when constructing large-scale projects, a large amount of plywood is required for splicing. However, the bonding position between traditional plywood is small, which easily leads to insufficient tightness and firmness in the splicing of plywood, easily affects the splicing efficiency of plywood, and results in poor splicing effect of plywood. The present application aims to provide multiple splicing components between plywood, and by simultaneously installing and splicing the inner core board and the surface board of the plywood and the adjacent plywood, the tightness and stability of the plywood splicing are strengthened, and at the same time, the installation convenience of the plywood is improved, and the splicing efficiency of the plywood is increased.
