Abstract

(57) [Summary] [Purpose] To provide a bamboo pillar made mainly of bamboo, which is inexpensive and has excellent strength. [Structure] Bamboo 1 is chopped in the lengthwise direction to form a horizontally long rectangular cross-section, and an elongated bamboo material 2 that is slightly thinner toward the top is formed.
The adjacent bamboo materials 2 were turned upside down and adhered in parallel. The parallel bamboo material groups 2a were arranged side by side to form a bamboo collecting pillar a having a predetermined cross section, and the outer surface was finish-cut to form the pillar surface 3. Characteristic bamboo pillars.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 It relates to bamboo pillars, which are pillar materials for buildings.

[0002]

[Prior art]

 Traditionally, cedar and cypress are the highest grade materials for building pillars because of their beauty and durability, but because they are expensive, cheap wood is pasted with a high-quality split board. Posts are often used. However, it takes 50 years or more for cedar and cypress to grow, and even if it is used as a tension material, a good quality tension material will be considerably expensive.

[0003]

[Problems to be solved by the device]

 The present invention solves the above problems by using bamboo as a material for the pillars, focusing on the abundance of bamboo resources and the short growth of the bamboos for three years. The technical challenge is to provide superior bamboo pillars.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The bamboo 1 is shredded in the longitudinal direction to form a horizontally long rectangular horizontal cross section to form a thin bamboo material 2 which is slightly thinner toward the upper side, and the adjacent bamboo materials 2 are turned upside down and bonded in parallel. The present invention relates to a bamboo pillar, characterized in that a row of bamboo material groups 2a are arranged and a bamboo collecting pillar a having a predetermined cross section is adhesively formed, and an outer surface is finish-cut to form a pillar surface 3.

[0006]

[Action]

 Since the adjacent bamboo materials 2 are placed upside down and side by side, the whole can be adhered and formed into a rectangular columnar body of approximately the same thickness in the upper and lower parts, facilitating the finish cutting process.

[0007]

【Example】

 The drawing shows a good example of the present invention. Bamboo 1 is chopped in the longitudinal direction to form a rectangular with a horizontal cross section to form an elongated bamboo material 2 that is slightly thinner toward the top. It is characterized in that the bamboo bamboo poles a having a predetermined cross section are adhered and formed by adhering the parallel bamboo material groups 2a side by side and adhering them in parallel, and the flat surface 3 is formed by finish cutting. It is related to bamboo pillars.

[0008] A single bamboo piece 2 having a rectangular horizontal cross section is cut by cutting a piece of mothau bamboo 1 cut from a bamboo forest in the length direction. If the length is about 1 m, about 200 can be created. However, since the upper part of the bamboo has a smaller diameter, it becomes a little thinner in the upper part, so it is easy to make a bamboo collecting pillar with a square cross section by adhering adjacent bamboo materials 2 in parallel upside down. When forming a long bamboo gathering pillar а, jointing is not performed at the same position, but the bonding of the parallel bamboo material group 2а is shifted up and down to join, and the upper part of the lower parallel bamboo material group 2а is also adjusted according to the resulting irregularities. If they are staggered and spliced together, it will become a strong bamboo pillar.

As the adhesive material, a synthetic resin adhesive having excellent heat resistance and water resistance such as epoxy resin having a strong adhesive force is used.

The square bamboo pillars formed in this example and the square cedar pillars of cedar having the same cross-sectional area and length were prepared, and the strength experiment was conducted. As a result, the square bamboo pillars of this example are more rectangular. It was found that the strength was 5 times stronger than cedar pillars, and the elasticity and durability were also excellent.

[0011]

[Effects of the Invention] Since the present invention uses an inexpensive bamboo splitting material for the material of the pillar as described above, the bamboo pillar is cheaper than the conventional wood pillar and has excellent strength.
