指接是木工中最常见、最稳定的木材长度接头类型之一. 它也称为梳状接头或盒式接头. 期限 “指接” 在木工中用于描述两块木头互锁时形成的接缝类型. This type of joint has been used by carpenters for centuries, with the earliest examples appearing in French carpentry manuals from the 15th century.
This joint is usually made by cutting a set of complementary interlocking profiles into the ends of two pieces of wood; these are then glued together to form a strong and secure joint that resembles the interlacing of fingers, 因此得名 “指接”.
This method can be used to join two pieces of wood at any angle, creating a joint with excellent strength and stability. 指接通常比对接接头更坚固，可用于连接未完全对齐的木块. This makes them ideal for carpentry work, and as a result, finger joints are often used in the construction of furniture, cabinets, and other wooden items.
指关节主要有两种类型: non-structural and structural. Non-structural joints have shorter fingers (针脚) and are mainly used in furniture making. 另一方面, the fingers of structural joints are longer and pointed, providing the necessary strength for applications such as flooring and roofing.
Box joint
Box joint, also known as square joint, is a method of joining two pieces of wood together by interlocking.
Box joints are commonly used at corners to join two pieces of wood together at right angles. Although it has similarities to dovetail joints, unlike dovetail joints, which have beveled tails and pins, box joints consist of straight fingers that mesh with each other. This joint consists of interlocking square fingers and grooves to form a visually appealing symmetrical pattern, and is specifically used in the manufacture of boxes, cabinets, 帧, and similar items.
Finger joints
Finger joints, also known as tapered joints, are used to join two pieces of wood together end to end, allowing for the manufacture of longer lengths. Unlike box joints, finger joints have interlocking tapered fingers and grooves.
Finger joints are generally more widely used in various joinery applications that require a strong interlocking joint. This interlocking design provides strength and stability to the joint. It can be used to join wood pieces lengthwise and at right angles in a variety of woodworking applications.
Why choose finger joints?
The most obvious advantage of finger joints is that they can effectively utilize smaller wood pieces, 产生具有良好机械性能的材料. By connecting individual wood pieces with finger joints, they can become finger-jointed wood, 具有与实木相当的强度特性.
同时, joints also provide a visually appealing symmetrical design for wood assemblies. The uniform and symmetrical characteristics of finger joints can add a clean and professional appearance to woodworking projects.
此外, this type of mortise and tenon joint is very easy to assemble. Interlocking finger joints make it easy to properly align the individual parts for a precise fit. Unlike dovetail joints, 它们不是机械互锁的, 但其较大的胶水表面积确保了与现代粘合剂结合时的强度.
Finger joints are widely used in woodworking because they are strong and versatile, 这使得它们成为家具和橱柜制造的理想选择. 此外, this kind of joints are beautiful and can be used to create furniture with complex designs. It can be said that finger joints are a carpenter’s “best friend” in woodworking activities.
