In general, in order to make a fence in a single house or other facility, a pillar is erected, and a plurality of wooden or plastic fence panels are installed based on the pillar. In this case, when the plastic panel is applied to the fence, the plastic itself is not environmentally friendly and has the disadvantage of artificial feeling. When the panel for the fence is made of natural wood, it feels natural but is not affected by moisture or other factors. Due to the disadvantages of weakness due to corrosion, in recent years, there is a trend to prefer a fence panel made of synthetic wood. Fence posts also prefer to be made of synthetic wood. In addition, the floor finishing panels and building roof deck material in the building interior is also a trend to prefer synthetic wood panels than solid wood. Like this, synthetic wood is widely used in various building materials.

In the case of building materials made of synthetic wood materials, there is a natural feeling and the price is cheaper than solid wood, but in terms of strength, it is inferior to that of wood or synthetic materials, so it is necessary to insert the reinforcement core material into the insert. In other words, it is essential to reinforce through the reinforcement core material in order to sufficiently ensure the strength as a building material.

However, conventionally, the synthetic wood itself is made into a hollow body having a space therein, and the structure is reinforced by embedding a metal reinforcement core in the space inside the synthetic wood, so that the bonding force between the metal reinforcement core and the synthetic wood is later There are a lot of gaps and gaps between them, and furthermore, the gap between them leads to the bending of the synthetic wood itself. There is a problem going into the dual. As described above, synthetic wood is used in various fields, such as deck material, floor material or fence panels of buildings, if there is an undesirable surface as described above may be a problem in construction reliability and the like.

An object of the present invention was developed to solve the problems described above, the object of the present invention is to increase the bonding strength between the reinforcing core material of the metal material and the composite wood body to increase the reliability of the product and construction reliability, and when applying as a building flooring It is to provide a strength-enhanced synthetic wood and a method of manufacturing the same that can achieve a desirable result, such as reducing the number of installation of the reinforcing material to reduce the construction cost.

According to the present invention for solving the above problems, the reinforcing core member 30 is formed of a hollow tubular shape of a metal material having a space portion therein, and the reinforcing core material 30 is inserted into the inner space 21 It comprises a composite wood body 20, the reinforcement core 30 is formed in a hollow pipe shape of the cross-sectional square, the corner portion of the reinforcement core material 30 is treated with a rounding portion 34, at the same time the reinforcement Core material 30 is provided with a projection 32 on a surface facing the inner surface of the space portion 21 of the synthetic wood body 20, the projection 32 by the reinforcement core material 30 and the synthesis Strength-enhancing synthetic wood is provided, characterized in that the wood body 20 has a structure that is bonded and reinforced.

In addition, according to the present invention, the process of injecting the reinforcing core material 30 of the metal material into the interior of the synthetic wood molding frame, molten synthetic wood molding at the outer surface position of the reinforcement core material 30 is introduced into the synthetic wood molding frame A process of inserting the material into the reinforcing core material 30 to the synthetic wood body 20 and inserting the reinforcing core material 30 into the internal spaces 21 and 31 of the synthetic wood body 20. Strength-enhancing synthetic wood is provided, including the process of cold-curing the synthetic wood 100.

The present invention inserts the reinforcing core of the metal material into the interior of the synthetic wood molding frame and insert the molten synthetic wood molding material at the outer surface position of the reinforcing core material to insert the reinforcement core into the interior of the synthetic wood body, then the composite wood body portion and reinforcement By cooling and hardening the core portion, it is possible to provide a strength-enhancing synthetic wood and a manufacturing method thereof in which a reinforcing core of a metal material is inserted therein. By adopting the manufacturing method, it is possible to prevent the case where the manufacturing process of the synthetic wood is required twice, and the effect of reducing the production cost as well as the production cost can be obtained by reducing the manufacturing man-hours.

In addition, the present invention is sufficiently secured the bonding force between the reinforcing core material and the synthetic wood body of the metal material does not occur a lot of gaps later, the construction reliability and the like due to the strengthening of the bonding force between the reinforcing core material of the metal material and the synthetic wood body. It has an advantage that can be sufficiently secured, and also, when using a synthetic wood as a flooring material, it is possible to install the base reinforcement, that is, the horizontal beams and stringers more wider than the conventional, it can achieve a desirable effect, such as construction cost savings.

Particularly, in the present invention, a plurality of protrusions are formed separately in the reinforcing core of the metal material, thereby increasing the bonding force between the composite wood body and the reinforcing core material by such a protrusion, thereby improving product reliability as the strength of the synthetic wood is further improved. It can be upgraded, and securing such high product reliability means that construction reliability in various facility constructions can be further improved.

On the other hand, the reinforcement core is a metal material, which is different from that of the synthetic wood body, so that the coefficient of thermal expansion of the reinforcement core and the synthetic wood is different. In the present invention, since cracks may occur, the above-described cracks can be prevented by treating the rounded portion of the metal reinforcement core with a curved rounding part without leaving the corner portion of the metal reinforcement core sharply, and such viscosity also improves the product reliability and construction reliability of the synthetic wood. Can be a guaranteed property.

Referring to this, the present invention provides a synthetic timber body 20 having a space 21 therein, and a reinforcing core 30 of a metal material inserted into the space 21 of the synthetic wood body 20. Strength-enhanced synthetic wood and manufacturing method comprising.

The reinforcing core material 30 is formed in a hollow pipe shape having a rectangular cross section, and the corner portion of the reinforcing core material 30 is treated with a rounding part 34 without leaving it sharp. The reinforcement core 30 is a metal material and is different from the synthetic wood body 20 so that the thermal expansion coefficients of the reinforcement core 30 and the synthetic wood 100 are different, and thus, when the corner portions of the reinforcement core 30 are left sharply, Since the wood body 20 may be cracked at the corner portion of the reinforcing core material 30, in order to prevent such cracks, the corner portion of the reinforcing core material 30 is treated with the rounding part 34, and such reinforcing core material (30) The rounded portion 34 of the corner portion is meant to ensure the strength of the synthetic wood (100).

In addition, the reinforcement core 30 is provided with a protrusion 32 on a surface facing the inner surface 21 of the inner space portion 21 of the synthetic wood body 20, the protrusion 32 is synthesized with the reinforcement core material 30 Between the wooden body 20 will have a structure that is bonded reinforced. The reinforcing core 30 is inserted into the inner space 21 of the composite timber body 20 and bonded to each other. The reinforcing core 30 and the composite timber body 20 have a function to increase the bonding force between the joints. The protrusion 32 is to be done. In addition, in order to insert the reinforcing core material 30 into the inner space 21 of the synthetic wood body 20, an adhesive is applied to the outer surface of the reinforcing core material 30, and the protrusion of the outer surface of the reinforcing core material 30 is 32 will also function to bond the adhesive and the composite wood body 20 well.

In addition, the outer surface of the reinforcing core material 30 is scratched, it is possible to have a structure in which the bonding force of the reinforcing core material 30 and the synthetic wood body 20 is further reinforced by this scratching. At this time, the reinforcing core material 30 may be made of a general metal or stainless steel material. In this case, the reinforcing core material 30 may be configured in a cross-sectional square pipe shape having a hollow part inside by folding a metal plate.

In addition, the reinforcing core material 30 may be made of an aluminum material extruded long in consideration of formability and cost. When the reinforcing core material 30 is made of aluminum, since the strength may be weaker than that of general metal or stainless steel, it is preferable that the reinforcing core material 30 is provided with reinforcing ribs extending in the longitudinal direction.

Hereinafter, with reference to Figure 6 will be described a method for producing strength-enhanced synthetic wood of the present invention.

First, the reinforcing core material 30 of a hollow tubular shape having a hollow part is molded. The reinforcing core material 30 is made of a metal material, and may be made by folding a metal plate or a stainless plate into a rectangular cross section or made of extruded aluminum. In this case, the plurality of projections 32 may be made in the reinforcing core material 30 by making the plurality of protrusions 32 in the longitudinal direction through processing on the metal plate or the stainless plate itself. As described above, since the corner portion of the reinforcing core material 30 and the cross-sectional rectangular pipe shape are formed, four corner portions are treated with the rounding portion 34.

Surface treatment of the reinforcing core material 30 formed as described above is performed. In the surface treatment process of the reinforcing core material 30, the main task is to remove rust, etc., by removing the rust by turning the steel brush on the surface of the reinforcing core material 30, rub with sand paper, turn the grinder or sandblaster Rust can also be removed. When sandblasting is used, sand may be removed after rust removal.

Subsequently, the outer surface of the reinforcing core material 30 may be scratched to form an irregular surface. The scratch is to serve as an auxiliary so that the reinforcing core 30 is more strongly bonded to the synthetic resin layer through the adhesive, it may be scratched during the surface treatment process of the reinforcement core 30 or may be formed by a separate scratching operation. .

After the surface treatment and the scratch treatment for the reinforcing core material 30 is finished, an adhesive is applied to the outer surface of the reinforcing core material 30 and cured. This adhesive is to increase the adhesion between the reinforcing core 30 and the synthetic wood body 20, the curing time after the application of the adhesive is maintained between 20 minutes to 24 hours.

As described above, the reinforcing core material 30 of the metal material coated and cured with the adhesive is introduced into the synthetic wood molding frame. It is a process to inject the reinforcement core material 30 of the metal material so as to secure a spaced space on the outer surface of the inner cavity and the reinforcement core material 30 of the synthetic wood molding frame. Since the reinforcing core material 30 may be input and transported in a state spaced apart from the cavity of the synthetic wood molding frame by a known transport mechanism, a detailed description of the transport mechanism will be omitted.

While the metal reinforcement core 30 is transferred to the cavity inside the synthetic wood molding frame, the molten synthetic wood molding material is introduced to the outer surface position of the reinforcement core 30 so that the metal reinforcement core 30 is made of the synthetic wood body 20. Insert in the By injecting the molten synthetic wood 100 material through the injection portion of the synthetic wood molding frame is a process for the metal reinforcement core material 30 is inserted into the synthetic wood body (20). At this time, while supplying the molten synthetic wood molding material while continuously supplying the reinforcing core material 30 of the metal material cut to a certain length in the form of a square pipe, the reinforcing core material 30 is inserted into the inside of the composite wood body 20 or a single long rectangular pipe By supplying the reinforcing core material 30 in the form to insert the reinforcing core material 30 in the synthetic wood body 20 as described above, or folding the metal plate to make a reinforcement core material 30 of the rectangular pipe shape and such a reinforcement core material 30 To put into the cavity of the synthetic wood molding can take the manner of having the synthetic wood body 20. Either way, you can choose to cook according to your working conditions.

At this time, the reason for setting the curing time of the adhesive within 20 minutes to 24 hours as described above is as follows. The adhesive will cure in about 20 minutes.The reason for setting the dry curing time of the adhesive within 20 minutes to 24 hours is that the dust on the work site (especially in the workplace without dust removal) is accumulated on the adhesive as it floats a lot of dust. Since the foreign material layer may later cause a peeling phenomenon by dropping the adhesive force with the synthetic wood body 20, the reinforcing core material 30 must be used up to 24 hours before. On the other hand, if the adhesive is cured for 24 hours or more, the adhesive is hardened more than necessary, and thus the adhesive is prevented from preheating and appropriately melted, so that it does not exceed 24 hours. In other words, the reinforcing core material 30 and the adhesive applied thereto are preheated by an indirect heat source such as an infrared ray of the heater before the reinforcing core material 30 is injected into the cavity of the synthetic wood molding frame and the molten synthetic wood molding material is injected. The adhesion between the adhesive and the composite wood body 20 is increased only by preheating, but when the curing time of the adhesive is 24 hours or more, the adhesive is hardened so that the adhesive is made of the composite wood body 20. Since it does not become a molten state for bonding well with, the curing time of the above adhesive is within 24 hours.

As described above, the reinforcing core material 30 of the metal material coated and cured with the adhesive is inserted into the molten synthetic wood molding material injected while being transferred to the cavity of the synthetic wood molding frame, and the reinforcing core material 30 is made of synthetic wood through the adhesive. It is possible to mold the synthetic wood 100 bonded to the body 20.

Next, the hardened core material 30 of the metal material is cooled and cured while transferring the synthetic wood 100 having a structure having the composite wood body 20 inserted along the transfer line. At this time, it is important that the reinforcing core material 30 is cooled by supplying cooling air to the outer surface of the composite timber body 20 into which the insert is made, so that the hardening of the synthetic wood body 20 is first performed. Since the coefficient of linear expansion of) is greater than the coefficient of linear expansion of the synthetic wood 100 and only the reinforcing core 30 of the metal is cooled down and then reduced, the peeling phenomenon occurs between the reinforcing core 30 and the synthetic wood body 20, and thus such peeling occurs. This is to prevent the phenomenon. In other words, since the linear expansion coefficient of the reinforcing core material 30 of the metal material is larger than the linear expansion coefficient of the synthetic wood 100, the coefficient of linear expansion of the synthetic wood 100 by blowing cooling air from the outer surface of the composite wood body 20 The coefficient of linear expansion of the metal reinforcing core material 30 is adjusted to be the same, and thus, the composite wood body 20 and the reinforcing core material 30 are not peeled off while cooling.

On the other hand, when the heat is sprayed and hardened inside the reinforcing core material 30, the linear expansion coefficient of the synthetic wood body 20 and the linear expansion coefficient of the reinforcing core material 30 of the metal material can be equally matched, so this method may be used.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various permutations, modifications, and changes can be made without departing from the spirit of the present invention. It will be apparent to those who have it.
