Description

A hollow protecting structure of tree

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint protection structure of a tree that can protect a cavity formed in a tree in a breathable state, and more particularly, to a joint protection structure of a tree that can shield a cavity surface in a breathable manner.

In general, Korea is specially managed by designating natural monuments and protected water, such as temple pond, Nomoki, Gogi, Nogu, and 畸形 木. Out of these trees, the pine tree is often exposed to the outside by wind waves.

The cavity is formed by the following: ① when the bark is split due to the firing phenomenon, the bark is formed to be exposed to the outside as the bubbles progress from the upper part to the upper part; or ② when the bark is broken and the bark is peeled off, ③ When the bumps are progressed due to cuts of stems or branches, they are formed in the interior of the trees without being exposed to the outside while proceeding from the upper part to the lower part.

If the cavity is left untouched, it will be corrupted or damaged by bacteria or insects. Therefore, the tree can survive until the site where the cavity is formed through surgical operation is treated.

The above-mentioned surgical operations are usually carried out in the order of removal of the decayed portion → exposure of the joint edge formation layer → insecticide sterilization and preservation treatment → cavity filling → waterproof treatment → artificial bark treatment → antioxidant treatment. At this time, the cavity is filled with a filler such as epoxy resin, unsaturated polyester, polyurethane or urethane rubber.

However, in the surgical operation as described above, the filling material 24 inside the cavity 12, which is shielded by the artificial bark 22 as shown in FIG. 1, is made of a material different from the wood 10, A space is created between the packing 24 and the inner surface of the cavity 12 as the container 10 is expanded and contracted.

Therefore, when performing the conventional surgical operation as described above, the fine inflow from the wounds of branches or branches permeates into the space formed between the filling material and the inner surface of the cavity 12, , There is a problem of accelerating the edge of the cavity 12 while being in the aforementioned space. In particular, conventional surgical operations do not evaporate due to the non-breathable packing 24 that is absorbed in the above-mentioned space, so that the humidification state is maintained for a long time or the edge is promoted more quickly.

There is also a problem that a pest of a small size penetrates into the space between the filling material and the cavity 12.

Particularly, the cavity 12 formed in the branch 19 of the tree 10 is in contact with the ground as shown in Fig. 2 and at the same time, is organically connected with many branches at the upper part. Therefore, It is even more vulnerable to the problem. In other words, since the cavity 12 formed in the support 19 is in contact with the ground, it is not only more vulnerable to the above-described problem due to the temperature difference of the ground, but also receives the rainwater from various directions through the plurality of branches formed at the upper portion. It is even more vulnerable to the problem.

1, reference numeral 10a denotes a core portion located at the center of the tree 10, 10b is a residual portion located on the outer side of the core portion 10a, 10c denotes a surface of the remaining portion 10b (10). ≪ / RTI >

The applicant of the present invention has applied for a patent developed to solve the above-mentioned problem in Korea and received registration (Registration No. 10-1167256, surgical apparatus for joint operation of tree).

The above-mentioned patent discloses a shield which shields the open portion of a cavity formed in a tree, and is made of a breathable material and protects the cavity while ventilating outside air; And a supporter for ventilating the shield in a state of being fixed to the inside of the cavity to prevent the shield from being collapsed, wherein the shield is integrally fixed to the rim of the cavity, Shielding net; A fibrous filter which is superimposed on the shielding net to protect the shielding net in a breathable state and performs antibacterial and insecticidal action; And an artificial skin which is coupled to the surface of the filter to provide a synthetic shell corresponding to the shell of the tree at the opening of the cavity and in which air holes in the form of voids are formed to vent the air outside do.

The above patent discloses that a supporter composed of a rod such as a stud bolt is installed horizontally in a hollow space and shields the hollow space while inserting the shield while inserting the shield so that the hollow can be kept empty at all times. Therefore, it is possible to maintain the moisture content of the cavity at 18% to 35% or less while preventing intrusion of rot fungi or insect pests, thereby preventing expansion of the cavity due to cavitation.

In addition, since the supporter is installed in the inside of the cavity without being installed on the outside of the tree, it does not interfere with the growth of the remainder of the tree. Therefore, there is also an effect that the remainder portion of the tree can be continuously and largely grown.

However, the above-mentioned patent has a somewhat insufficient hygroscopic effect, is somewhat complicated to install, and has a risk of fire.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted.

FIG. 4 is a side cross-sectional view of a tree showing a common extension of the common protection structure of a tree according to the present invention, and FIG. 5 is a cross- Sectional view of a tree showing another embodiment of the common protection structure of trees according to the present invention.

The joint protection structure of a tree according to the present invention comprises a filling material 100 filled in the upper side cavity formed in the upper side cavity of the tree part and filled in the side part cavity formed in the side part of the tree, And a release preventing member for preventing the filler 100 from coming off.

The upper cavity is formed in a branch extending from the tree, and the upper cavity is formed to have a size larger than that of the root cavity small.

Thus, the filler cavity or the upper side cavity formed in the tree T is filled with the filler 100 so as to fill the inside thereof. As shown in FIG. 3, the filler 100 is filled with a sterilized or insecticide-treated wood (T), which absorbs humidity of the cavity to adjust the humidity of the cavity, It is kept at a constant humidity to prevent the trees from decaying.

In particular, the filler filled in the filler cavity may be a charcoal mass 50, wherein the charcoal mass is formed to a size of 0.5 mm to 1.5 cm.

Since the charcoal mass 50 is a porous material, it absorbs moisture to regulate humidity, has an antimicrobial and detoxifying action, has a side effect, and absorbs ethylene gas, which is an aging substance, And beneficial materials such as calcium, sodium, iron, magnesium, potassium, phosphorus, and other necessary minerals such as minerals can be supplied to the trees.

When the filler material 100 made of the charcoal material 50 is filled in the cavity of the tongue part as described above, there is a risk that the charcoal material 50 may escape through the inlet of the filler cavity, do. This release preventing member is composed of a network 70 and fixing means.

The porous network 70 is formed with pores having a size smaller than that of the charcoal mass 50 and shields the cavity filled with the charcoal mass 50 so as to ventilate to prevent the charcoal mass 50 from escaping So that air is supplied to the charcoal mass 50.

It is preferable that the network 70 is formed by folding a conventional zinc-plated steel wire in a double-folded manner. Instead of such a wire mesh, it may be formed of a plate having a plurality of holes.

The fixing means fixes the multi-network 70 to the tree T as shown in FIG.

The fixing means may be formed of a pin, for example, a conventional tacker, and may fix the multi-network 70 to the tree T so as to shield the cavity filled with the char block 50.

The cavity extension part communicates with the cavity, and the charcoal mass 50, The gravel S is sequentially filled to allow the moisture of the cavity to drain to the ground and to supply air to the cavity.

Preferably, the cavity extension is formed in the form of a groove on the ground after artificially communicating when the cavity of the tree T is not in communication with the ground.

At this time, it is preferable that the tree T is artificially communicated only when the cavity is close to the ground for growth.

The cavity extension is formed on the ground in the form of a groove and communicates with the lower end of the cavity as shown in FIG. 5, and the char bundle 50 and the gravel S are sequentially charged.

The joint extension may be laid on top of the gravel S such that a gravel (S) is not detached from the gravel (S).

Here, the gravel S is laid to protect the charcoal mass 50 from being stepped on by pedestrians.

Meanwhile, as shown in FIG. 5, the polygonal mesh 70 is coated with a plaster 80 to shield the surface.

As shown in FIG. 5, the plaster (80) is coated on the surface of the multi-perforated network (70) to shield the surface of the multi-perforated network (70) It suits.

That is, the plaster 80 hides the network 70 to make the surface of the tree T look beautiful.

The plaster (80) is made of at least one of seaweed grass or vegetable gelatin so as to be produced environmentally friendly.

Here, the plaster (80) is one of the traditional Korean ceramics materials, and is used continuously in a building or a hanok designated as a cultural property, and has excellent breathability, water repellency and magnetic cracking characteristics, To 18 times. Therefore, the moisture generated inside the cavity can be absorbed together with the char block 50.

Also, since the plaster 80 is known to have superior water-repellent ability than clay or cement, the moisture introduced into the cavity from the branches of the tree T can be smoothly discharged.

Further, it is known that the plaster (80) is capable of treating self-cracking due to moisture or moisture at the time of moisture absorption due to the above-mentioned pressure-sensitive adhesive.

The plaster (80) is added with a reinforcing material for reinforcing the tensile strength and mixed with the pressure-sensitive adhesive.

The reinforcing material is made of porous coconut fiber capable of absorbing moisture.

At this time, the coconut fiber is mixed in 2 to 7 parts by weight with respect to 100 parts by weight of the plaster (80) mixed with the pressure-sensitive adhesive so as to prevent the viscosity of the plaster (80) from being weakened.

The coconut fiber is cut to a length of about 1.5 cm to 4.2 cm so as to facilitate mixing of the plaster (80).

If the coconut fiber is cut to a length of 1.5 cm or less, the length is too short so that it can hardly reinforce the tensile strength even when mixed with the plaster 80. When the coconut fiber is cut to 4.2 cm or more, So that it is preferable to cut and cut to a length of about 1.5 cm to 4.2 cm as described above.

The reinforcing material is composed of the coconut fiber because the coconut fiber is superior in physical properties to other natural fibers and has superior air permeability because it is porous and has an antibacterial effect so that the fiber is superior in performance to other fibers, ).

The plaster 80 mixed with the reinforcing material as described above is sprayed on the surface of the dendritic network 70 by a sprayer such as a shotcrete machine in the form of a plaster and then hardened at the surface of the dendritic network 70 do.

At this time, the plaster (80) is inserted into the inside of the multi-network (70), and the multi-network (70) is embedded in the interior of the multi-network (70).

On the other hand, the plaster (80) is coated with a flame retardant paint (90) that fires a fire of the tree (T).

The flame-retardant paint (90) protects the fragile tree (T) from the influence of the number of years vulnerable to fire or fire in winter.

The flame-retardant paint 90 may be mixed with pigments and may be mixed with pigments of a color corresponding to the bark of the tree T so as to alleviate the sense of unevenness of the tree T.

Meanwhile, as shown in FIG. 5, the network 70 is spaced apart from the entrance blocking network M in the front direction.

The entry / exit network M protects the network 70 and the plaster 80 by blocking entrance of people or animals.

In the joint protection structure of a tree according to the present invention as described above, the charcoal mass 50 is filled in the cavity of the tree T so that the charcoal mass 50 absorbs the moisture of the cavity, Generation absorbs harmful substances such as ethylene gas, which is an aging substance, to prevent aging of plant cells. It also provides beneficial ingredients such as minerals necessary for trees such as calcium, sodium, iron, magnesium, potassium and phosphorus as well as antibacterial and detoxification functions To thereby grow the tree T in a healthy manner.

Also, the porous network 70, which shields the cavity and prevents the char bundle 50 from being separated from the cavity, is separated from the surface of the cavity by the spacer 60, And can easily be charged between the cavity and the network 70.

And the coarse extensions are formed on the ground surface, and then the cavity is connected to the cavity, and the charcoal masses (50) are charged in the cavity and the cavity, respectively, The moisture of the cavity can be absorbed smoothly.

The plaster 80 is applied to the surface of the porous net 70 so that the plaster 80 is plastered in a state in which the surface of the porous net 70 can be ventilated and absorbed, And the viscoelasticity of the plaster 80 can be shielded by the environmentally friendly material by forming the viscous with the seaweed grass or the vegetable gelatin, The flame retardant paint 90 may be applied to the surface of the plaster 80 to improve the tensile strength of the plaster 80 by mixing the coconut fiber with the reinforcing material. And it is possible to naturally shield the cavity by mixing pigments similar in color to bark to the flame-retardant paint 90.

In addition, by providing the entry / exit network M in front of the network 70, the plaster 80 and the network 70 can be protected from the outside.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various changes, substitutions, and alterations can be made therein without departing from the spirit of the invention.

For example, the filler 100 to be filled in the upper side cavity may be a mixture of the urethane foam 101 and the activated carbon 102. This will be described with reference to FIG.

6 is a side cross-sectional view of a tree showing another embodiment of the filler in the joint protection structure of the tree according to the present invention.

Referring to the drawings, when the filler 100 is made of a mixture of the urethane foam 101 and the activated carbon 102 and is filled in the cavity, it is possible to closely fill the inside of the cavity by the foaming property of the urethane foam 101 The cost can be reduced because the cost of the material is lower than that of filling the cavity with the charcoal mass 50.

That is, the activated carbon 102 having the same effect as the charcoal is mixed with the urethane foam 101 and filled in the cavity, so that the humidity inside the cavity is controlled by the numerous pores of the urethane foam 101 and the activated carbon 102 The inside of the cavity is prevented from being decayed or deteriorated by the antibacterial and detoxifying action which is characteristic of the activated carbon 102.

In order to apply the filler 100 formed by mixing the urethane foam 101 and the activated carbon 102 to the cavity, the activated carbon 102 is mixed with the polyurethane before the foaming to form the urethane foam 101. At this time, The activated carbon 102 is mixed with 5 to 30 parts by weight per 100 parts by weight of the polyurethane.

If less than 5 parts by weight of the activated carbon 102 is mixed with 100 parts by weight of the polyurethane, the amount of the activated carbon 102 is too small to expect the effect of the activated carbon 102. When the activated carbon 102 is mixed with more than 30 parts by weight of the polyurethane with respect to 100 parts by weight of the polyurethane, the polyurethane hardly bubbles smoothly in the cavity, and the urethane foam 101 is not tightly filled in the cavity. Therefore, the activated carbon 102 is preferably mixed in 5 to 30 parts by weight with respect to 100 parts by weight of the polyurethane.

When the pre-expanded polyurethane is mixed with the activated carbon 102 and filled in the cavity, the urethane foam 101 tightly fills the inside of the cavity while the polyurethane is foamed.

At this time, it is preferable that the mixture of the urethane foam 101 and the activated carbon 102 is filled in the pores formed on the upper part of the paper. Since the pupil formed on the upper portion of the paper is smaller in size than the pupil formed in the lower portion of the paper, the polyurethane is foamed and hardened in the pores even though the porous network 70 and fixing means are not provided at the entrance of the cavity The urethane foam 101 and the activated carbon 102 are placed in a stable state in the cavity.

Since the urethane foam 101 tightly filled in the cavity as described above is mixed with the activated carbon 102, the activated carbon absorbs the ethylene gas, which is an aging substance generated in the tree, to prevent the aging of the tree cells, and calcium, sodium, The beneficial materials such as iron, magnesium, potassium, phosphorus and other necessary minerals can be supplied to the trees, which will help the trees to grow.

On the other hand, a hollow pipe (P) can be installed to facilitate the ventilation of the cavity, which will be described with reference to FIG.

7 is a side cross-sectional view of a tree showing the installation of a hollow tube in a joint protection structure of a tree according to the present invention.

Referring to the drawings, a hollow pipe P provided in a cavity extends through the porous network 70 from the inside to the outside of the cavity.

When the hollow pipe P extends through the porous network 70 from the inside to the outside of the cavity, the inlet of the hollow pipe P extending outwardly of the cavity is formed to be bent toward the ground.

When the inlet of the hollow pipe P is bent toward the ground, rainwater or the like is prevented from flowing into the cavity through the hollow pipe P, thereby preventing the inside of the cavity from being excessively humidified.

In addition, the entrance of the bent hollow pipe (P) is provided with an insect control panel (P1) for blocking foreign matter such as insects from entering the cavity of the tree through the hollow pipe (P) .

At this time, a slit is formed along the periphery of the outer circumferential surface adjacent to the inlet of the hollow pipe P so that the insecting net can be firmly fixed to the inlet of the hollow pipe P. The insect control network P1 contacts the inlet of the hollow pipe P, The strap can be seated on the slit and the insect protection net P1 can be firmly fixed.

In addition, the present invention may be provided with a hollow pipe (P) and a filler (100) in the upper side cavity to facilitate the ventilation of the upper side cavity formed in branches extending from the tree (T). This will be described with reference to FIG.

FIG. 8 is a schematic view showing the installation of a hollow tube to the upper side cavity of the joint protection structure of a tree according to the present invention. FIG. In the case of the upper side cavity, a hollow pipe P is disposed inside the upper side cavity, and then a filler 100 composed of a mixture of the urethane foam 101 and the activated carbon 102 is placed in the upper side cavity And the inlet of the upper side cavity is closed.

When the hollow pipe P and the filler 100 are provided in the upper side cavity as described above, the urethane foam 101 is hardened and the hollow pipe P is fixed so as not to move. The inside of the upper side cavity can be closed by ventilation smoothly, thereby protecting the trees.
