Description

Round logs within reinforcement pipe}

The present invention relates to a core material reinforcement main wood, more specifically, to the inside of the hollow thin timber main wood removing the core (Pith), iron or graphite (Graphite) or FRP (Fiber glass Reinforced Plastic, glass fiber reinforced plastic) By providing the core material of the pipe made of the pipe, etc., it is lighter than the wood and ensures sufficient strength against external impact, as well as forming a male thread and a female thread on both sides of the core reinforcement column, It is intended to facilitate the extension in the direction.

In addition, by drying the main wood with the core removed, the core wood reinforcement prevents cracking of the main wood due to stress and improves the aesthetics of the structure according to the recent trend of pursuing environmentalism. It is to provide a columnar wood and its manufacturing method.

In general, fences, railings, guardrails, etc. are mainly installed by welding or bolting steel plates to the pillars of steel pipes, and for the purpose of indicating road boundaries, preventing pedestrians from falling down, and lane departure from vehicles. Is installed.

Recently, due to the influence of environmentalism, the use of raw materials produced in the natural state is increasing in the structure of civil engineering or construction field, and in particular, the use of wood, such as timber is frequently used.

In keeping with these trends, construction of the fences, railings, guardrails, and the like described above is increasing.

On the other hand, in order to use the main wood such as thinning materials as a structure in the field of civil engineering or construction, it is necessary to dry the main wood which has been lumbered. Due to the stress generated during the drying process, cracking defects occur toward the center of the core at the outside of the main wood.

Therefore, in the case of columnar wood, a method of cutting and digging in the fiber direction to the depth of the number toward the center of the number is used, that is, forming a crack prevention line to prevent cracking at other sites.

However, this allocation process is difficult to select the direction because it should be distributed in the portion close to the number of times due to the crack prevention line formed in the longitudinal direction on the surface of the main wood, the top and bottom of the main wood is determined during installation, etc. It is inconvenient to use, and there is a problem such that the center of the columnar is also divided in appearance.

In addition, when installing fences, railings, guardrails, etc. using timbers such as columnar wood or lumber, in the process of extending the installation in the horizontal direction, joints of different columnar wood or lumber, etc. are forcibly customized or There is a difficulty in connecting by using a lumber, etc. This part also became a factor that undermines the aesthetics of the structure.

In particular, since the weight of the main wood itself is considerably heavy and the strength is inferior to the weight, it was difficult to carry the main wood as well as to install a structure such as a fence, a railing, a guard rail, and the like.

In order to solve the above problems, the present invention is made of iron, graphite or FRP (Fiber glass Reinforced Plastic), etc. By providing a pipe made of, it is to provide a core reinforcement column wood that is lighter than the solid wood and can ensure sufficient strength against external impact.

In particular, the male and female threads are formed on both sides of the core reinforcement column, so that the installation in the horizontal direction can be facilitated.

In addition, by drying the main wood with the core removed, the core wood reinforcement prevents cracking of the main wood due to stress and improves the aesthetics of the structure according to the recent trend of pursuing environmentalism. In providing the main tree.

In other words, eco-friendly wood replaces marker posts, railings, bicycle road borders, road boundary fences, roadside props, guardrails, benches around roadsides, and pagoras that increased natural environment and discomfort by using steel. It can be harmonized with natural scenery, and can be used for staircase handles, handrails for handicapped persons, veranda railings, rafters, etc. for indoor use, and is intended to provide core wood reinforcement applicable to a wide range of fields.

In order to achieve the above object, the core material reinforcement columnar according to the present invention, in the core material reinforcement columnar (A) is inserted into the core material 20 is reinforced by the inside of the columnar wood 10,
Digging the inside of the columnar wood 10 so that the space 110 is formed,

Strength can be guaranteed.

In particular, it is possible to considerably lighter weight than the solid wood, including the seam (Pith) is very easy to handle and transport, as well as when connecting to connect a number of core reinforcement raw wood, there is almost no joint joint mark of the seam, Since there is no need for framing like ordinary wood, construction time can be shortened and labor costs can be greatly reduced.

In addition, in the case of general wood mainly by preventing the swelling (material is badly changed by the action of bacteria) or building pests that occur at the junction, there is an effect that can improve the durability.

In addition, in the case of fences, railings, guardrails, etc., the most time-consuming part in the assembly of wood is the seam part, or it is produced by integrating it with props in the production process, and it is easy to connect the fence to the produced props easily. Handrails, guard rails, etc. can be installed.

Moreover, when installing the structure of the civil engineering or construction field using the core wood reinforcement column according to the present invention, the structure can be naturally harmonized with the natural landscape, such as landscaping, interior and exterior materials, such as the wide range of use, It has the effect of improving the competitiveness of the product.

Examples for the core reinforcement columnar according to the present invention can be applied in various ways, hereinafter with reference to the accompanying drawings will be described for the most preferred embodiment.

1 is a partial cutaway perspective view showing an example of a core material reinforcement columnar according to the present invention, hollow thinning columnar column 10 and steel, graphite (Graphite) or FRP (Fiber glass reinforced plastic, glass fiber reinforced plastic) Consists of a core material 20 made up.

The hollow thin timber main column 10 is dried after removing the inner seam [pi,], the internal thread of the thread portion 111 in the inner peripheral edge of the space portion 110 is removed (Pith) ). Here, the columnar wood 10 is preferably embalmed to prevent swelling (the material is rotted by bacteria or the like).

The core material 20 has a hollow pipe shape, and a male thread 211 corresponding to the female thread 111 of the column wood 10 is formed at an outer circumferential part thereof, as described above for strength reinforcement. Like it is made of iron or graphite or FRP. Here, the core material 20 is preferably rust preventive treatment to prevent corrosion.

When the core material 20 is made of iron, it is easy to supply and produce materials, and when the carbon fiber is carbon treated at high temperature, the strength can be further strengthened. Is unnecessary and light, but can also be strengthened, as well as easy to process.

Core material reinforcement columnar wood (A) according to the present invention is made by screwing the core material 20 to the space portion 110 of the columnar wood 10 as described above, as shown in FIG. The female threading groove 120 is formed by inserting deeply into the inside of the target 10 (from the upper right direction to the lower left direction).

At this time, if the length of the cylindrical wood 10 and the length of the core material 20 is the same, as shown in Figure 1 can be formed male threaded portion 130.

Therefore, by screwing the male thread fitting portion 130 of the other core material reinforcement column A to the female threading groove 120 of the core material reinforcement column A shown in FIG. Can be installed.

If the length of the columnar wood 10 is longer than the length of the core material 20, when the core material 20 is inserted into the center of the columnar wood 10, female threaded grooves 120 to both sides of the columnar wood 10 ), And if the length of the columnar wood 10 is shorter than the length of the core material 20, the male threaded portion 130 can be formed on both sides of the columnar wood (10).

Therefore, by adjusting the length of the column 10 and the core 20 according to the needs of those skilled in the art, it is possible to provide a core reinforcement column (A) having a variety of coupling forms.

On the other hand, when the length of the columnar wood 10 as described above is long, it may be difficult to form the female thread 111 in the space portion 110 of the columnar wood (10).
