Description

Extruded Deck, manufacturing method and construction method of the extruded deck {Extruded Deck, manufacturing method and construction method of the same}

The present invention relates to an extrusion deck, a manufacturing method and a construction method of the extrusion molding deck, and in particular, a deck body composed of synthetic wood material, a resin layer composed of resin, and a coating layer of synthetic urethane material, the deck having a triple structure is extruded. Using the material characteristics of the molded extrusion deck, it satisfies heat insulation, abrasion resistance, flame retardancy, heat resistance and moisture barrier performance, thermal expansion coefficient, accelerated weather resistance and slip resistance, and is laminated in a triple structure. In the construction structure of the structure, it can be easily installed on the support frame and constructed, and the structure is improved to improve the drainage performance of the extruded deck in close contact in the lateral direction, and the manufacturing method and construction method of the extrusion deck It is about.

In general, recently, demand for civil engineering and construction materials that are lightweight while having high strength has been continuously demanded. Accordingly, an extruded product called Wood Plastic Composite (WPC), which is manufactured by mixing wood and plastic having a surface texture and pattern similar to natural wood, is in the spotlight.

In the case of the WPC, it is mainly produced by melting and extruding wood flour and various additives to various thermoplastic resins such as polyethylene and polypropylene.

WPC has several advantages, such as excellent processability of plastic, beautiful appearance of wood, and high strength, low price, and diversity of application compared to existing wood or plastic single materials. .

It is important to design to prevent slip accidents because many people step on the deck materials of trails and mountain trails, whose use has recently been spreading.

In particular, since there are many elements that can cause slippage, such as high humidity or rain or snow, on outdoor decks, walking trails, and stairs, the anti-slip function is most important, so a concave-convex pattern is formed on the surface of synthetic wood. or by forming grooves in the longitudinal direction to give a non-slip function.

Conventionally, to prevent slipping, a concave-convex pattern is formed on the surface of synthetic wood or a groove is formed in the longitudinal direction to give an anti-slip function. As you pass by, the surface wears out quickly and the anti-slip function is lost.

As a conventional prior art for improving this, as disclosed in Korean Patent Registration No. 10-2141518 "double-extruded synthetic wood deck panel with excellent slip resistance" (registration date: 2020.07.30), the core part contains 100 parts by weight of olefin resin. 10 to 200 parts by weight of wood flour, 1 to 50 parts by weight of filler, and 1 to 10 parts by weight of binder, and the skin part contains 1 to 20 parts by weight of wood flour, 1 to 20 parts by weight of filler, and a crosslinking agent based on 100 parts by weight of olefin resin. 0.1 to 5.0 parts by weight, styrenic thermoplastic elastomer or EPDM / PP resin 1 to 100 parts by weight, adhesion improver 1 to 15 parts by weight, UV stabilizer 1 to 5 parts by weight and binder 1 to 5 parts by weight Characterized by including To provide a synthetic wood deck material with excellent slip resistance.

The above technology is extruded with a dual structure of the core part and the skin part, but due to the nature of the different materials of the core part and the skin part, there is a concern that it may be easily separated by external force, and thermal expansion and contraction are severe due to external temperature changes in summer and winter. When it occurs, there is a concern that twisting deformation may occur, and as heat is easily conducted from the floor surface to the pedestrian side, there was difficulty in walking according to climatic conditions.

Other conventional prior art related to the above deck construction method is as disclosed in Korean Patent Registration No. 10-2217099 "Synthetic wood deck assembly and construction method with improved durability due to strengthening of coupling structure" (registration date: 2021.02.10) Likewise, in constructing a composite wood deck assembly with improved durability due to the strengthening of the coupling structure, the fixed top plate of the reinforcing frame integrally assembled with the composite wood deck is fixed and installed at the top of each base pipe using screws, and the fixed top plate On the bottom surface of the lower plate located on the upper side, the connecting protrusion of the reinforcing frame assembled integrally with the other synthetic wood deck is fitted and fixed so as to be in close contact with each other to integrally connect a pair of adjacent synthetic wood decks in the width direction.

The above technology is a method in which a reinforcing frame integrally assembled with a composite wood deck is fixed to the top of each base tube with screws, and a connection protrusion of a reinforcing frame assembled with another synthetic wood deck is fitted to the bottom of the lower plate located on the upper side of the fixed top plate of the reinforcing frame. While the composite wood deck and other synthetic wood decks are constructed so that they are aligned in the width direction as they are fixedly connected, moisture penetrates into the synthetic wood in the case of rain or snow and after a long time passes, the synthetic wood In addition to deformation, there is a possibility of deformation due to thermal expansion and contraction in the longitudinal direction.

Subsequently, the resin application step is performed from the resin supply hopper 520 located on the upper surface and the left and right sides of the deck body 100 extruded while passing through the die 500 toward the lower deck body 100. A liquid resin is injected to form a resin layer 200 having a certain thickness.

Thereafter, a synthetic urethane material in liquid form is injected into the upper side of the resin layer 200 in the urethane supply hopper 530 spaced apart from the resin supply hopper 520 so that a coating layer 300 having a certain thickness is laminated.

The resin layer 200 and the coating layer 300 are formed so that the resin and the synthetic urethane material are laminated in a multi-layer structure on the upper body 110 of the deck body 100 after a certain period of time has elapsed, and the upper body 110 It is extruded with a triple structure extrusion molding deck in the form of wrapping around the upper surface and both left and right sides.

At this time, the resin of the resin layer 200 serves as an adhesive for bonding the coating layer 300 to the deck body 100.

As the extrusion deck 10 of the present invention is extruded in a triple laminated structure of the coating layer 300, the resin layer 200, and the deck body 100, the coating layer 300 is the extrusion deck 10 Since it is located at the upper part exposed to the outside in the deck structure to be constructed, it has excellent insulation to block heat conduction upward from the deck body 100 according to external temperature changes in summer or winter, and even in rain or snow, the lower side Advantages of the extruded deck 10 having excellent moisture barrier performance to block the transfer of moisture to the lower body 120 side of the deck body 100, and excellent wear resistance, accelerated weather resistance, flame retardancy, heat resistance and slip resistance have

In addition, the present invention is excellent in the coefficient of thermal expansion in the longitudinal direction even if the extrusion deck 10 expands or contracts in the longitudinal direction according to the external temperature change even after the construction of the deck structure is completed and the coating layer composed of a synthetic urethane material having its own elasticity (300) is able to respond to the change in length of the deck body 100, thereby minimizing the deformity factor causing cracks or twisting of the deck body 100.
