Abstract

PURPOSE:To effectively use even a remnant material without scrapping it by engaging pipes of desired length with both engagement parts of a joint member furnished with a brim part having a bamboo knot-like outer peripheral shape and the engagement parts extending from both sides of the brim part until end faces of the pipes make contact with the brim part. CONSTITUTION:Though remnant materials 1, 2 are furnished with knots 11, 21 on their one side end parts, they are short to assemble a bamboo rail fence. A joint member 3 has a brim part 31 in the middle, and engagement parts 32 vertically extend on both sides of the brim part 31. The brim part 31 has its central part which is larger in diameter than the outer diameter of the remant materials 1, 2, bamboo knot-like grooves 31a are formed on its outer periphery and the outer diameter of both end edges 31b is roughly same as the outer diameter of the remnant materials 1, 2. The engagement parts has a columnar shape with almost the same outer diameter as the inner diameter of the remnant materials 1, 2, and after adhesive is applied on the engagement parts 32, the remnant materials 11, 2 are engaged with the joint member 3 from both sides until end faces 11, 21 make contact with the brim part 31, and the remnant materials 11, 2 are jointed and integrated. Consequently, it is possible to use even short remnant materials as materials to assemble a bamboo rail fence like normal bamboo materials.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for pipes.

[0002]

2. Description of the Related Art As shown in FIG. 3, a bamboo fence 4 has long been used as a fence surrounding a site in Japanese architecture.
After cutting a long bamboo material such as artificial bamboo made of natural bamboo or synthetic resin into a desired length as a unit member 41 of the bamboo fence 4 at a site or a factory, the unit member 41 is fixed to a fixing member 42 such as a palm.
It is designed to be assembled by using.

[0003]

However, as described above, when a long bamboo material such as natural bamboo or artificial bamboo made of synthetic resin is cut into the unit members 41 having a desired length, it is inevitably short. A large amount of semi-milled wood that cannot be used as a material is generated. Conventionally, waste materials are treated by incineration or landfilling, but especially in the case of bamboo made of synthetic resin, harmful gas is emitted when incinerated, and even if it is landfilled it does not decompose easily and there is a problem of environmental pollution. Occur. Moreover, it is very difficult to find the landfill site, and there is a problem that the disposal process is very expensive.

In addition, recently, the global environment summit and the like have been opened, and resource conservation is being actively promoted all over the world, and effective use of these semi-finished materials is desired. In view of such circumstances, an object of the present invention is to provide a connecting structure for a pipe-like object that enables even a scrap material to be effectively used without being treated as waste.

[0005]

In order to achieve such an object, a pipe-shaped article connecting structure according to the present invention extends from both sides of a brim having a bamboo knot-shaped outer peripheral shape and both sides of the brim. The pipe member having a desired length is fitted to both fitting portions until the end face abuts on the flange portion, to the connecting member having the fitting portion that extends.

In the above structure, the structure of the fitting portion is preferably cylindrical or cylindrical, but is not particularly limited as long as it can be fitted to a pipe-like material, and the fitting portion has elasticity to facilitate fitting. Therefore, the shape may be such that a slit is provided at the tip of the cylinder. Also, apply an adhesive to the outer wall surface of the fitting part,
At the same time as the fitting, it is preferable that the fitting portion is joined and integrated with the pipe-shaped material.

[0007] The pipe-like material includes not only natural bamboo and artificial bamboo half-ends, but also general pipes and half-ends thereof.

[0008]

According to the above construction, the pipe-shaped material and the pipe-shaped material are connected to each other through the bonding member, and the flange of the bonding member is longer than the pipe-shaped material which looks like a bamboo node. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing the embodiments thereof. FIG. 1 shows an embodiment of a bamboo-shaped material connected by a connection structure for a pipe-shaped material according to the present invention, and FIG. 2 shows the bamboo-shaped material of FIG. 1 in a disassembled state. As shown in the figure, the bamboo-shaped material A includes a semi-finished material 1 and a semi-finished material 2 made of a synthetic resin bamboo material as a pipe-shaped material.
The structure is such that they are connected via the connecting member 3.

More specifically, the semi-milled materials 1 and 2 are provided with the joints 11 and 21 at one end, respectively, but the length is short to assemble a bamboo fence. The connecting member 3 has a collar portion 31 in the middle thereof, and fitting portions 32 extend vertically on both sides of the collar portion 31. The collar portion 31 has a central portion having a diameter larger than the outer diameters of the semi-finished materials 1 and 2, and a bamboo knot-shaped groove 31a is formed on the outer periphery thereof. It is almost the same.

The fitting portion 32 has a cylindrical shape having an outer diameter substantially equal to the inner diameters of the half end materials 1 and 2. Then, the bamboo-shaped material A is obtained by applying an adhesive to the fitting portion 32 of the connection member 3 and then applying the semi-milled materials 1 and 2 from both sides to the end surfaces 11, 12.
The half end materials 1 and 2 are connected and integrated via the connection member 3 by fitting until 21 abuts on the flange portion 31, respectively. Moreover, since the flange 31 has the groove 31a formed on the outer periphery and has the shape of a bamboo knot, the joint looks like a bamboo knot.

Therefore, by using this connection structure, even a short half end material 1 (2) can be used as a material for forming a bamboo fence 4 as shown in FIG. The connection structure of the pipe-shaped material according to the present invention is not limited to the above-mentioned embodiment. For example, in the above-mentioned embodiment, the artificial bamboo half-end material was used as the pipe-shaped material, but it can also be used for connecting the natural bamboo half-end material. Moreover, not only half-end material but also ordinary pipes are cut to a desired length, and the cut pieces are connected by a connecting member. Can also be used as

EFFECTS OF THE INVENTION Since the pipe-like material connection structure according to the present invention is constructed as described above, it is possible to obtain a long bamboo-like material having knots by connecting end materials having short dimensions. It is possible to reuse this bamboo-shaped material as a bamboo fence. Therefore, it becomes possible to use the scrap materials without discarding them, which is very effective for resource saving and environmental protection. In addition, there is no need for disposal costs, and costs can be reduced.

Further, according to this joint structure, the number of knots can be increased and the positions of the knots can be freely changed, and the effect of improving the designability of the bamboo fence or the like can be obtained.
