Description

Artificial pine tree

The present invention relates to artificial pine sculptures and, more particularly, to a sculpture that can be used as artificial pine trees, street trees, lamps having a pine shape.

Many columnar structures are installed and used in cities such as street lamps and telephone poles. These structures, formerly made of wooden columns, are often made of steel or reinforced concrete structures.

However, these structures often hurt the aesthetics of the city, and in recent years, although the columnar structures are made of artificial materials to reflect the preferences of the natural people and the natural landscape of the urban people, the appearance forms the natural structures. Growing.

For example, there were cases where the poles and street lamps were made of plastic material and shaped like tree trunks, and benches were made of reinforced concrete, but the bark pattern and shape were added to the exterior, and the rings were painted, and the trees were painted. In many cases, the shapes such as knots and stumps of trees are expressed and imitated. Christmas trees are often made of plastic resin and wire in the form of artificial pine or artificial fir.

Existing such sculptures mimic the form of natural objects, typically trees, but the shapes are often unnatural, and they are often made of concrete, which makes them heavy and not easy to manufacture or handle.

In addition, even if the outer shell and leaves of a tree trunk are expressed in plastic, as is often used in artificial Christmas trees, the branches and leaves are expressed uniformly on the main trunk of trees with a straight appearance, so that they are more awkward than the beauty of nature. I often gave.

Also, in terms of appearance, when time passes in the air and especially when it is exposed to sunlight, the polymer compounds constituting plastics are easily deteriorated and are easily broken and discolored to change viciously. For example, polyethylene, which is a representative polymer compound, is deteriorated and weakened due to photooxidation when ultraviolet rays are irradiated, and carbonyl group (CH ₃ ) is formed in the polymer as deterioration occurs. do. In addition, polypropylene is also sensitive to ultraviolet energy and is thought to trigger a free radical chain reaction that causes polymer destruction. PVC also undergoes ultraviolet rays to decompose hydrogen chloride, which increases the number of double bonds in the polymer. It is known that chains are cleaved or molecules are crosslinked.

If discoloration, discoloration, or deterioration occurs due to such deterioration, the small Christmas tree can be simply discarded, but if large outdoor structures such as roadside trees, landscape trees, and street lamps are fixedly installed, it may adversely affect the urban aesthetics. There was a problem that the problem and the cost of reconstruction were not small.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide an artificial pine sculpture closer to a natural form and a manufacturing method thereof.

An object of the present invention is to provide an artificial pine sculpture and its manufacturing method which are easy to handle or move with reduced weight.

It is also an object of the present invention to provide an artificial pine sculpture which can be maintained in its original state for a long time without rework, and a method of manufacturing the same.

Artificial pine sculpture manufacturing method of the present invention for achieving this object, the step of preparing a reinforcing armature, wire coil spring form or the shape of the armature reinforcement in the form of a rib, such as reinforcing armature reinforcement skeleton wood Forming a frame of the body, combining the reinforcing bar body with the reinforcing bar branches, covering the reinforcing bar branches and the wire mesh on the outside of the frame of the wooden body and sprinkled with flexible foamed polyurethane, Forming a nonflammable layer on the polyurethane foam made of a solid polyurethane foam, characterized in that it comprises a step of attaching the pine bark using the silicone coating as an adhesive while the silicone coating on the nonflammable layer.

In the present invention, the nonflammable layer may be formed of a cement layer or a remittal layer.

Artificial pine sculpture of the present invention for achieving this object is a wooden frame frame made by combining the reinforcement structure to a plurality of reinforcing bars in parallel in the longitudinal direction, a tree branch coupled using the reinforcement of the frame for the wooden body , Wire frame installed outside the main tree trunk and tree branches, polyurethane foam bonded over the wire mesh, nonflammable layer formed on the polyurethane foam, silicon layer formed on the nonflammable layer and pine bark attached to the silicon layer, It is installed on a tree branch and consists of a wire core or a pine needle made by forming a paint film or synthetic resin coating on the wire core.

In the artificial pine sculpture of the present invention, the wire core for pine needles may be made of galvanized wire, and the pine bark may be made of FRP.

In the present invention, when the electrical facilities are combined, such as using artificial pine sculptures as street lamps, the electrical wiring inside the frame for the wooden body, the electrical wiring can be installed inside the pipe insulation made of foam of synthetic resin material.

According to the present invention, the interior of the frame for the wooden body is filled with a foam of a light synthetic resin material such as an empty space or polystyrene foam, and the outside of the frame may be made of a light porous material such as a polyurethane foam, so as to produce a molding such as light artificial pine as a whole. .

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Referring to the flowchart of FIG. 1, first, a main frame for a wooden body is prepared to implement the method of the present invention.

Preparing the frame for the wooden body consists of a reinforcing armature preparation step (10) and a skeleton reinforcing structure preparation step (20). The armature reinforcement structure may be in the form of a coil spring made of wire as shown, or in the form of a rib that bends the rebar roundly. When preparing the reinforcing armature, it is a longitudinal skeleton to form a frame, and according to the thickness and size of the wood, the main reinforcing bars are prepared with diameters of 10 mm, 13 mm, and 16 mm, and bend the reinforcing bars according to a desired body curve. Here we make a gentle S-shaped curve.

Apart from the preparation of the reinforcing armature, next, wire 8 (4mm in diameter) is wound on a pipe selected from 100mm to 200mm in diameter by 3cm intervals to produce a coil-shaped spring with an inner diameter of 100mm to 200mm. .

Raise the reinforcing bar for the body prepared above, and arrange the spring in the longitudinal direction of the reinforcing bar and couple it to the rebar. When combined, where the reinforcing bar and the spring meet together, the reinforcing bar and the spring in some of the wires as necessary to form an S-shaped model frame as a frame for the wooden body (30).

At this time, the reinforcing bars can be arranged in parallel with each other along the circumference of the circle formed by the spring on a flat section, and in order to make a more robust structure can be tied to the main reinforcing bar at 25cm intervals to the main bar reinforcement of the 10mm diameter rebar .

In addition, the wire spring wound in the form of a coil for a wooden body can be easily coupled to a plurality of rebars installed in parallel without being strongly bounded in shape even when the reinforcing steel for the wooden body is naturally bent in a soft spring state. Make sure

In step (40) of inserting electrical wiring and pipe insulation into the frame for the wooden body, the pipe insulation made of a diameter smaller than the circle formed by the spring is made into a long pipe in the longitudinal direction. This makes it possible to reduce the overall weight of sculptures, such as artificial pine trees, to be completed while filling a substantial portion of the internal space of the wooden frame.

Pipe insulation is often made of expanded polystyrene, commonly referred to as styrofoam, but may also be made of other foams or porous insulating materials. An aluminum foil for reflecting heat may be used on the surface of the pipe insulation, and since a pipe insulation that is easily bent and bent is commercialized, a detailed description thereof will be omitted.

Since the inside of the pipe insulation is an empty space, the electrical wiring can be installed using this empty space. Therefore, when the pipe insulation is put in the wooden frame, it is preferable to put the electric wiring in the pipe insulation beforehand.

Next, a branch forming step 50 is formed to connect the portion of the artificial pine to the reinforcement of the frame for the wooden body. Like a tree body, a part that becomes a branch may be formed by paralleling a plurality of rebars, or a frame or a skeleton may be made of a single bar. For connection, it is recommended to weld the reinforcing bar and reinforcing bar reinforcing bar, reinforcing bar reinforcing bar and reinforcing bar reinforcing bar.

The connection of the twigs or pine needles to the branches can also be done at a later stage, for example after the polyurethane foam forming step or the bark attachment step, in which case the twigs and pine needles can be made using wires, especially galvanized wires. Can be.

Hereinafter, referring to FIG. 2, an example of a method of making a small branch 320 and a pine needle 330 is first galvanized by cutting a 0.5 mm diameter wire into approximately 10 cm in size. In the galvanizing process, the color may be directly colored green, but if the color is not clear, the galvanized wire may be painted green, or a synthetic resin such as green PVC or a silicone resin coating may be applied.

On the other hand, in order to make a small branch (320), the wire diameter of 1,2mm or 30cm or necessary length is cut and galvanized to change the color only with the same color as the pine needles (330), and then fold the middle and twist it like a pretzel. .

In the middle of twisting the branching wire, insert the pine needle end, which is made up of a few green pine needles wires, between the small branching wires so that about 180 pine needles are inserted into each small branching wire.

On the other hand, the folded branch wire ends are painted with brown paint added with stone powder to form the shape of the brush 340 to complete the small branch 320 into which the pine needle 330 is inserted, and the opposite end of the folded branch wire. Binds to coarse pine branches.

At this time, in the case of applying paint or synthetic resin for color development of the pine needles 330 or the twigs 320, the galvanized wire is immersed in the oil paint, liquid silicone, or liquid synthetic resin, which is liquid due to solvent or high temperature, and then taken out. A method of dropping, curing or drying the liquid can be used.

In addition, the small branch 320 may be made by inserting a bark-shaped part made of plastic material or insert injection into a rather thick wire core. In the case of attaching the accessory, the small branch 320 may be connected to the pine needle first by weaving a wire core of the small branch and the wire forming the pine needle or pine needle end before adding the bark accessory with a plastic material.

By using this method, the tape is conventionally used to combine the pine needles with small branches, and then the color of the small branches is not used. Therefore, the tape deteriorates and the attachment life of the small branches and pine needles is shortened. The need for replacement can be reduced.

Then, a wire mesh installation step 60 is formed in the wooden body portion and the large branch portion that needs to attach the flesh of the tree to install the wire mesh with a tightly spaced gap on the outside. Next, in the polyurethane foam forming step 70, the foamed polyurethane is sprayed in a state of fluidity by controlling a solvent or a temperature on the wire mesh. In this case, the wire mesh serves as a base material to increase the thickness of the polyurethane layer by stacking the foamed polyurethane. That is, some foamed polyurethane flows through the wire mesh, some of which fills the inside, and some are piled up on the wire mesh, and when the solvent component contained therein is volatilized and solidified at room temperature, the polyurethane foam layer wraps around the wire mesh and hardens.

When sprinkling foamed polyurethane over the mold, where electric wiring is branched, such as a lamp or an electrical outlet, spray the foamed polyurethane and remove the polyurethane foam and expose the electrical wiring. You can also install a protective structure and spray the foamed polyurethane so that it doesn't build up from scratch.

When the polyurethane foam is sufficiently hardened, a nonflammable layer is formed through the nonflammable layer forming step 75 thereon. This is because resin products such as polyurethane foam are generally advantageous to realize lightweight moldings, but are vulnerable to fire. As a nonflammable material layer, a cement mortar layer using a cement layer or a remittal is formed by about 2 to 3 mm. The thickness of the nonflammable layer may vary depending on the type of the nonflammable layer. If the thickness is too thin, it is difficult to perform the nonflammable function. If the thickness is too thick, the weight of the finished product is increased. Cement or remittal layer is good adhesion with the polyurethane foam, so there is no need to install a separate layer for adhesion.

When a nonflammable layer is formed, a step 80 of applying a silicon on it and attaching the pine bark on the silicon layer using the silicone as an adhesive is performed. At this time, the silicon may be seen between the pine bark, so it is preferable to have a color such as brown, maroon, etc. similar to the pine color, and since rain water may penetrate between the pine bark, apply it on the polyurethane foam tightly, and water does not penetrate well. It is desirable to use oily silicone to avoid.

In addition, this silicone work can be used for finishing the work of attaching a small branch to a large branch or stem, which may be done together with or just before the pine bark attachment.

Substantially, small branches are made integrally with pine needles but are formed separately from the tree body or large branches, and then are often combined with large tree branches, so the combination of small branches can be the step of combining leaves in the sculpture. Pine needles are pine green evergreen, so green to light green color, pine cones can be combined together. Adhesive may be used for bonding, but basically, the pine needles and pine cones are fixed by using a small branch wire.

On the other hand, the bark can be used natural pine bark, but as shown in Figure 3 by arranging the natural bark 280 on the surface of the rubber or silicon layer 270 using this to create a mold (mold: mold), this FRP can be poured into molds, released, and colored to make synthetic pine bark, and the pine bark can be cut to a suitable size.

In addition, the end of the electrical wiring is made to be exposed when viewed from the outside to connect the lamp or to install the outlet. A plurality of lights may be installed, or an electric (battery) -operated brush injector that emits a fragrance so that the fragrance of pine needles can be felt at a predetermined time interval or at a desired time point. If possible, install these parts by adjusting their shape or color so that they are not clearly distinguished from natural pine and do not feel heterogeneous. This step is not necessarily the only state in which the pine needles are combined, but may be performed in the step preceding it.

In addition, it is preferable that the pine bark is made of flame retardant treatment, or that the flame retardant component is included when forming a coating film on the pine bark.

Sculpture, such as artificial pine completed through the above steps may have an appearance and internal structure as shown in the conceptual diagram of Figure 4 and the partial cross-sectional view of FIG.

In Figures 4 and 5 you can see artificial pine sculptures with pine bodies that are largely curved in S.

The electrical wiring 110 passes through the most center, and the heat insulating material 120 for the hollow pipe exists around the electrical wiring 110. A spring 130 is formed by winding a wire in a coil shape around the heat insulating material 120 for piping. Spring 130 is coupled to the reinforcing armature 140 is installed side by side in parallel to each other around it, and all the reinforcing armature 140 is curved in the S-shape so that the spring 130 is also S-shaped in the coiled state It is curved and the heat insulating material 120 for piping and the electrical wiring 110 in it also comprise the curved S shape as a whole.

The nonflammable layer 165 is formed on the outer side of the polyurethane foam 160. The nonflammable layer may be formed of a cement layer or a remittal layer.

A brown or brown oily silicon layer 170 is laminated on the nonflammable material layer 165. A pine bark 180 made of FRP material is made of polysilicon by using the oily silicon layer 170 as an adhesive. It is attached to the nonflammable layer on the urethane foam 160 to form an artificial pine appearance.

Several thick branches 310 are coupled to the upper end of the wooden body. Coarse branch 310 may be formed as a skeleton of a simple reinforcing bar connected to the wooden body as shown in the drawing, but usually mesh mesh wire mesh 150 and polyurethane on the skeleton made by installing a few rebar in parallel, such as the wooden body It is made by adding the foam 160 and again by attaching the artificial pine bark 180 to the silicon layer 170 as an adhesive.

It can be formed by welding in several places.

In these coarse branches 310, a plurality of branches or branches 320 are branched along the longitudinal direction, respectively, such a small branch 320 is welded to each other with reinforcing bars forming the skeleton of the thick branches 310 After installation, it can be made by attaching a thin polyurethane foam layer on its surface as needed, or by simply attaching a silicone layer and pasting an artificial bark made of synthetic resin with a bark texture.

The small branch 320 and the thick branch 310 are combined with a plurality of places of the needle ends, which are bundled by a plurality of needle-shaped pine needles in the form of cones along the length direction, to form the pine needles 330. Needle-shaped pine needles can be formed by galvanizing the wire to develop green color or by applying green oil paint on the wire in the state to form a coating film, or dipping into green liquid silicone or synthetic resin solution, and then drying and curing the wire. .

The electrical wiring 110 is drawn out from the upper end of the wooden body, and the electric light 400 is coupled to the electrical wiring 110. The other end of the electrical wiring is drawn out to the bottom of the wooden body and is connected to a switch and a power supply (not shown) to turn the light on or off.
