Joint structure

Abstract

To achieve a joint structure which can extend not only in one direction (X) but also in three directions (X-Y-Z) freely by fixing two directions (X-Y).SOLUTION: A dovetail joint 1 having a dovetail shape on both sides is inserted into a square hole part of an I-shaped concave material 4 and slides into a portion cut-out into a dovetail shape, and an embedding piece 2 is inserted into the bored square hole and an added piece 3 is inserted into a groove part, and finally, an L-shaped concave material 5 is inserted and slides. Thereby, the two directions of X and Y are fixed. By combining and joining long and short four types of concave materials respectively having the connection structures of the I-type concave material 4 and the L- type concave material 5, extension can be possible in the three directions of X, Y, Z.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a joint structure. [Background technology]

[0002] Conventionally, joint structures using adhesive have been widely used.

[0003] As such a conventional technique, Patent Document 1 discloses a joining structure using a joint. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 09-184197 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the joint structure using the joint does not resist external forces in the longitudinal direction of the joint, so joints using adhesives or screws, nails, metal fittings, etc. are required. [Means for solving the problem]

[0006] As a means for solving the above problems, the present invention is characterized by using parasitic ants and buried seeds in addition to employed seeds.

[0007] Fix the two directions using the following procedure. 1. Insert the ant into the notch in the recessed material. 2. Slide the dovetail into the dovetail-shaped notch and secure it to the recess. 3. Insert the embedded part into the open notch. 4. Insert the piece into the groove to complete the formation of the convex part. 5. Insert the dovetail part of the convex piece into the notch of the concave piece to be joined, and slide it to secure it in place. [Effects of the Invention]

[0008] The present invention makes it possible to assemble structures by freely extending them in three directions: X, Y, and Z.

[0009] Extension is possible with a total of seven parts: I-type, L-type, two types of long and short lengths with directional characteristics, two types of concave materials, and three types of joint mediators: interlocking dowels, embedded dowels, and interlocking dowels. By standardizing the materials and dimensions of these seven types of materials and accumulating data, it becomes possible to accurately and easily carry out structural calculations for buildings using solid wood, which has a wide range of variations, and it is possible to reduce the use of unnecessary materials and adhesives, thereby reducing costs.

[0010] In addition, because the structure can be subdivided, high-strength hard hardwood materials are used in the parts that require strength, and ordinary cedar, cypress, and recycled materials are used in the parts that do not require strength, and scrap wood can be used for joining materials, leading to effective use of wood resources.Furthermore, because it is easy to disassemble and large structures can be formed from small parts, it is easy to recycle, reuse, and reduce wood, which reduces the environmental burden. [Brief explanation of the drawings]

[0011] [Figure 1] FIG. 1 is an explanatory diagram showing an embodiment of the method applied to a plate material (Example 1). [Figure 2] FIG. 2 is an explanatory diagram showing a method of applying the method to a square-shaped structural member (Example 2). [Figure 3] FIG. 3 is a cross-sectional view of a square-shaped structural material (Example 2). DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Example]

[0013] Fig. 1 is an exploded view of a member in which the present invention is applied to a plate material such as a shelf board. The upper and middle parts of the figure show the individual states of intermediate members: a side-mounted member, a recessed member, a side-mounted member, and a short middle plate with two I-shaped concave sides. The lower part of the figure shows the intermediate assembly state in which a side-mounted member, a recessed member, and a side-mounted member are attached to a long end plate with one side recessed. [Example]

[0014] Figure 2 shows an L-shaped short primary assembly and an L-shaped long primary assembly, with a concave L-shaped member on two sides, fitted with a joint, embedded joint, and joint. The bottom of the figure shows two sets of L-shaped short primary assemblies and a long primary L-shaped assembly put together in the L-shaped secondary assembly state. By fitting these two L-shaped secondary assembly members together and sliding them, a square-shaped structural member is completed. The cross-sectional view of Figure 3 shows the state in which the dovetail is attached to the dovetail-shaped notch of the recessed material. [Explanation of symbols]
