Problems solved by technology

The tooth length of the finger-joint tooth is about 5 to 15 mm. If the finger-joint is also used in the horizontal splicing of the plates that have been processed into a regular square, it will cause more serious material waste.

Embodiment Construction

[0013] Such as figure 2 The finger-joined glulam shown in the figure uses the burr of the unedged board to have finger-joining teeth 2 in the width direction of the board 1. The tooth tips 3 are like image 3 (b), (c), (d) are angular shapes, or they can be as image 3 (a) The linear shape shown in (a), or the shape of a broken line, an arc, or a curve. The width direction of the wood board is connected and glued by finger joint teeth. At least one or more finger joint teeth are connected to the plywood surface. not vertical. Finger teeth are shaped like image 3 (a) Straight tooth tip, (b) angular tooth tip, (c) curved tooth edge, (d) irregular tooth, all unequal tooth edges, two adjacent finger teeth are short edges The root of the tooth is directly connected with the root of the long side of the next tooth or connected by a straight line, a broken line, an arc or a curve, and a plurality of finger joint teeth are continuously connected to form a continuous finger joint tooth with...

Abstract

The invention relates to a decorating material of a finger jointed wood. Finger jointed teeth are provided in the width direction of planks by using rough edges of unedged planks. The width direction of planks is connected via the finger jointed teeth and glued. At least one or more than one finger joint teeth are not perpendicular to the surface of the glued planks. The finger jointed wood of the invention is reasonable in structure. Finger jointed teeth are arranged in the width direction of unedged planks and continuously arranged along the shape of arc-shaped rough edge of the unedged planks. The shape of the finger jointed teeth can be formed into both angle style and straight type according to requirement. When finger joint is in progress, only tooth profile joint of finger jointed teeth of two jointed planks is needed, and then finger joint is accomplished by other technical processes of glue joint, fixation and the like. Unconventional finger jointed teeth are provided according to the characteristics of unedged planks, and approximately 20% wood is saved.

Description

Technical field: [0001] The invention relates to decoration materials, especially glulam. Background technique: [0002] At present, my country's forest resources are increasingly depleted, and improving the utilization rate of wood has become one of the important tasks of conserving forest resources and building a conservation-oriented society. [0003] Nowadays, the general board processing technology: firstly cut the round wood into unedged boards, then use the saw to trim the unedged boards, process them into vertical planes perpendicular to the board surface, and then splice and glue them horizontally. In this traditional process, all the trimmed edges become firewood, which wastes about 20% of resources. The smaller the diameter of wood, the more serious this waste is. [0004] Finger-joining technology is a technology originated in Taiwan in the 1950s. The gluing strength is very good, and it is currently widely used, but finger-joining is mainly used for the lengthwise co...
