Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a scaffolding board for temporary construction, which is made by compressing bamboo material by press-molding bamboo pieces into aggregate and impregnating or mixing menmin resin as a bonding agent.

[0002]

[Prior art]

 Conventionally, as temporary scaffolding plates, wood veneer or plywood, as well as metal, particularly steel plate and aluminum plate, can be mentioned.

[0003]

[Problems to be solved by the device]

 Although the above-mentioned various types of temporary scaffolding plates for temporary construction, each of which has the advantages based on the material characteristics, are generally heavy and long, they are inconvenient to handle. There is. In addition, in the case of wood-based materials excluding those made of metal, the materials are subject to weather conditions as they are, deformation due to dry and wet action, low durability due to corrosion, etc. In the case of manufactured products, there is a dislike of rough handling due to the concept that the durability is large and the low workability due to the fact that it is heavy, so after removing after use, from the high place It may be dropped as it is, and it may be deformed or damaged.

As described above, various scaffolding boards made of different materials coexist with low workability due to the large weight in any case, and have disadvantages due to the characteristics of each material. Since there are many cases, we are trying to provide an improved temporary scaffolding board.

The object of the present invention is as a temporary scaffolding plate, which is not easily affected by weather, is lightweight and has good workability, can withstand repeated use over a long period of time, and can maintain accuracy even during repeated use over a long period of time. It is possible to provide a temporary scaffolding board obtained by compression-molding a bamboo material that can be used.

[0006]

[Means for Solving the Problems]

 As a means for achieving the above-mentioned object, the present invention has a sheet shape obtained by weaving a strip of bamboo material, which is a raw material, in a mold whose inner shape has a set dimension, and has a set strength and a set thickness. The obtained number of sheets is laminated and placed inside, and the set amount of melamine resin is filled, impregnated with the above-mentioned bamboo material, and this is pressed to form a scaffolding plate of the set shape. .

Further, the present invention is a bamboo material chip formed by crushing or cutting a bamboo material, which is a raw material, and a predetermined ratio of the bamboo material chip to which a predetermined ratio of melamine resin has been added and mixed evenly. It is made by filling the inside of a mold having a set dimension and press-molding it.

Further, the present invention is a bamboo material chip formed by crushing or cutting bamboo material between a plurality of sheets formed by weaving thin pieces of bamboo material, which is a raw material, in a formwork whose inner shape is a set dimension. Bamboo material layered with the above-mentioned sheet-shaped and bamboo chips while stacking and stacking a number of sheets to obtain the set strength and set thickness It is obtained by impregnating a layer, press-working it, and molding it into a scaffolding plate of a set shape.

[0009]

[Embodiment of device]

 The scaffolding board for temporary construction has a particularly strict standard in terms of strength from the viewpoint of human life, and a scaffolding board satisfying the numerical value of the standard or more is currently used.

Therefore, even when the degree of decrease in strength due to repeated use maintains the standard, those in which slight inconveniences such as corrosion, wear, and deformation are visually recognized are discarded or Only those which have been visually confirmed to be reusable are subjected to a strict strength test and then repeatedly used.

The first condition is the above-mentioned strength, but there is no regulation in terms of workability, and therefore it is important to focus on safety, that is, strength and durability. There is a hate that the workability is postponed because of the connection.

Therefore, the present invention proposes a scaffolding board which is lighter than the conventional scaffolding board, in which the requirements such as the strength of the first condition and the durability of the second condition are satisfied and the workability is emphasized. It was developed.

The temporary scaffolding plate 1 of the present invention is made of a composite material. That is, it is made up of two members, with the bamboo material 2 as the main aggregate and the melamine resin 3 for solidifying the bamboo material 2 as the auxiliary material.

Bamboo materials have not been used industrially as a main building material in a large amount for a long time. It is unsuitable as a construction material in terms of material and shape, and has low workability because the shape of the raw material is unspecified.

However, as is well known, the bamboo material itself is lightweight, has corrosion resistance, and has an advantage in that it can be supplied in a large amount because it takes a short period to reach maturity.

Therefore, the present invention has developed a technology that focuses on the advantages of the material properties of bamboo and uses it as the main material.

In the present invention, the materials used for the bamboo material 2 used as the main material are classified into two types. That is, with emphasis on the characteristic fiber quality, it is processed into a long thin strip according to the fiber direction and woven into a single sheet 2a, or the cortical part of the bamboo material 2 or The main material is the bamboo piece 2b which is obtained by crushing or cutting the individual flesh portions or the integral ones without distinguishing between them.

When the former bamboo material 2 in the form of a sheet 2a is used as a main material, the inner shape is desired as an aggregate of the scaffolding board 1 inside a formwork having the shape of the scaffolding board 1 desired. A plurality of sheets are laminated until the strength is obtained, and then the melamine resin 3 is filled and pressed to obtain a desired shape as the scaffolding board 1, and compression molding is performed.

Note that, in the molding method at the time of the compression molding described above, since the present invention does not make the manufacturing method the gist of the heating and the atmosphere as necessary, the details thereof will be omitted. .

In addition, a bamboo material chip b formed by crushing or cutting the bamboo material 2 as a raw material, and a material obtained by adding a predetermined ratio of the melamine resin 3 to the predetermined amount of the bamboo material chip 2b and mixing the two uniformly. The shape of the scaffolding plate is filled in a form frame having a set dimension, and is pressed to obtain a desired shape as the scaffolding plate 1, and compression molding is performed.

Furthermore, a bamboo material chip formed by crushing or cutting the bamboo material 2 between a plurality of sheet shapes 2a formed by weaving thin pieces of the bamboo material 2 as a raw material in a formwork whose inner shape is a set dimension. 2b is intercalated and is laminated and laminated in a number to obtain a set strength and a set thickness, and is filled with a set amount of the melamine resin 3 and layered with the sheet 2a and the bamboo chip 2b. It is formed by impregnating two layers of bamboo material, press-working this, and shaping it into the scaffolding board 1 of the set shape.

[Effect of device]

 As described above, the present invention requires a scaffolding board for temporary construction as a bamboo material, and uses this as a bonding agent with a melamine resin to form a sheet of bamboo or individual bamboo chips, or an aggregate composed of both of them. Formed as a binding material, it is lighter and more rigid than bamboo materials, and is lighter than conventional wood-based scaffold boards and metal scaffold boards due to its corrosion resistance and moldability with melamine resin. The temporary scaffolding board with high durability and durability can be provided at low cost.
