Description

{A Multifunctional wood floor deck system having a easy install structure}

The present invention relates to a wooden floor deck system installed and used in various environments such as beaches, lakesides, and forests. More specifically, in the process of installing a wooden floor deck system, separate fixing/fastening means such as screws or nails are omitted. Also, separate buffer members can be omitted, minimizing the number of parts and simplifying the installation structure, allowing for quick installation or disassembly on site. In particular, the deck connection structure applied to install the wooden floor deck system. By forming a coating layer that provides corrosion resistance and salt resistance functionality, and forming a separate coating layer that provides buffering, sound absorption, and durability functionality on the parts that come into contact with the deck plate and support frame of the deck connection part, it is possible to create a coating layer without the need for a separate buffer member. It is about a multi-functional wooden floor deck system that not only absorbs shock and prevents noise, but also ensures durability under various installation environments.

In general, walking trails or hiking trails that require smooth walking of people, such as parks, lakes, and mountains, are designed to create an eco-friendly and beautiful environment in accordance with the surrounding natural scenery, or to promote the safety and convenience of pedestrians in terrain where pedestrians are difficult to walk. Various types of floor deck systems are being constructed and used to create an optimal walking environment for people.

As the economy develops and income levels increase, deck systems including a floor made of wood and a railing partially made of wood coupled to the floor are being widely developed. These deck systems use wood, blend well with the surrounding environment and provide excellent aesthetics.

Looking at the basic structural composition of this floor deck, a fixed beam to support the overall structure on the ground depending on the terrain, a joist placed at regular intervals on the upper part of the fixed beam to serve as a support, and a joist seated side by side on the upper part of the joist It is composed of a floor plate that forms a walkable floor surface.

However, since the existing floor deck simply uses fastening means such as nails or screws to fix the floor plate to the joist, not only are these fastening means exposed to the outside, but also shock is applied to the feet when walking. There was a problem in that the feeling of walking was significantly deteriorated, and furthermore, when walking, the weight of the pedestrian and other impact factors, along with the resulting repetitive load, were transmitted to the floor plate and fastening means, causing breakage and damage to the structure.

In order to solve these problems, in newly introduced floor deck systems, fixing/fastening means such as screws or nails can be omitted, or additional cushioning materials, etc. can be used to increase the impact mitigation effect of the floor deck system. Although attempts have been made, in this structure, additional problems may occur, such as lowering the economic feasibility of construction due to the complicated fastening structure of the floor deck system or weakening the durability of the floor deck system.

Meanwhile, another feature of the floor deck system of the present invention is a coating layer (first coating layer 710) that provides corrosion resistance and salt resistance functionality to the deck connection part 30 applied to install the wooden floor deck system. Through its formation, it is possible to secure solid durability even under various installation environments, and additionally, a deck connection part that connects between the deck plate 50 and the deck plate 50 and between the deck plate 50 and the support frame 10. (30) In particular, the parts that come into contact with the deck plate 50 and the support frame 10 (i.e., the first insertion part 312, the first support part 313, the second insertion part 322, The second support portion 323) is formed with a separate coating layer (second coating layer 720) that provides various functionalities such as cushioning, sound absorption, durability, and flame retardancy, thereby providing shock absorption and noise prevention as well as robustness without a separate buffer member. It is characterized by ensuring durability. Hereinafter, the functionality of the first coating layer 710 and the second coating layer 720 applied here will be described in detail.

The first coating layer 710 contains 1 to 5 parts by weight of a silane compound, 1 to 5 parts by weight of calcium nitrate, and 1 to 5 parts by weight of nanoceramic particles, based on 100 parts by weight of a resin composition that is a mixture of an acrylic resin and a water-soluble resin. , 1 to 5 parts by weight of graphene, 1 to 10 parts by weight of clinker, 1 to 10 parts by weight of dihydrate and anhydrous gypsum mixture, 1 to 10 parts by weight of plaster, 1 to 5 parts by weight of silica fume, 1 to 5 parts by weight of dispersant, It is characterized in that it contains 1 to 5 parts by weight of a hardener, 1 to 3 parts by weight of a thickener, 1 to 3 parts by weight of a surfactant, and 1 to 3 parts by weight of a plasticizer.

The acrylic resin is included in the composition of the first coating layer 710, which has functions such as anti-salt damage and anti-corrosion, to provide anti-salt damage, anti-neutralization, and/or waterproof/corrosion performance for the surface to be protected. For this reason, any acrylic resin commonly used in the art may be used, but water-soluble acrylic resin is preferably used. Here, the water-soluble acrylic resin is strong against acids and/or bases, provides weather resistance to prevent discoloration or structural aging caused by ultraviolet rays, and can add surface gloss. Additionally, the acrylic resin can easily adhere to the target surface. It can provide adhesive strength that allows

The water-soluble resin is a resin composition made by mixing 70 to 99% by weight of glycidyl ether and 1 to 30% by weight of alkanolamine, and the water-soluble resin is a polyfunctional aliphatic glycidyl ether compound, arylalkyl glycidyl It is preferable that it is a reaction product of a glycidyl ether compound such as an ether (arylalkylglycidyl ether) compound and an alkanol amine such as ethanolamine, diethanolamine, and triethanolamine, and especially one containing two or more oxirane groups. It is preferable that the branch is a reactive resin of at least one glycidyl ether compound selected from glycidyl ether compounds and an alkanolamine. At this time, the glycidyl ether compound is rich in chemical reactions and has excellent heat resistance and chemical resistance, and the alkaline amine performs a corrosion prevention function.

The silane compound is used to allow the materials forming the first coating layer 710 to be easily bonded to each other. For this purpose, for example, perfluoroalkoxysilanes such as perfluoromethoxysilane and perfluoroethoxysilane are used. Alternatively, any tetraalkoxysilane such as tetramethoxysilane or tetraethoxysilane, dialkoxysilane, silane oxide, alkoxysilane, silane oxide, or a mixture thereof may be used. In particular, the silane compound increases chemical resistance, etc., and also functions to increase the durability of the first coating layer 710 by providing functionality to improve thermal stability and mechanical properties.

The calcium nitrate is used to form a calcium-based zinc phosphate film, and can provide calcium ions that improve surface properties such as wear resistance and corrosion resistance by refining the film crystals. The preferred amount of calcium nitrate used is 1 to 5 parts by weight based on 100 parts by weight of the resin composition.

Since the nanoceramic particles rise to the surface during curing of the first coating layer 710 to form a dense and high hardness surface, moisture resistance, durability, weather resistance, impact resistance, chemical resistance, etc. can be improved. The amount of nanoceramic particles used is preferably 1 to 5 parts by weight based on 100 parts by weight of the resin composition, and preferred nanoceramic particles may include silicon carbide, alumina, silica, zirconia-silica, ZnO, TiO2 and/or CaCO3.

The graphene is one of the carbon allotropes and has a structure composed of an atomic honeycomb lattice. It is also a material used as a water treatment filter in seawater desalination. This graphene can provide corrosion resistance that blocks the penetration of chlorine ions and can also provide corrosion resistance. The plate-shaped structure increases the strength of the first coating layer 710 and at the same time inhibits the movement of corrosive agents, thereby achieving a synergistic effect on corrosion resistance and increasing the adhesion and durability of the coating layer.

The clinker is composed of calcium silicates such as alite, berite, and cerite. The clinker serves to promote mixing of powder components and liquid components. The clinker is preferably contained in the range of 1 to 10 parts by weight based on 100 parts by weight of the resin composition. If the content of the clinker is less than 1 part by weight, it is not easy to mix the powder component and the liquid component, and if the content of the clinker is less than 1 part by weight, it is not easy to mix the powder component and the liquid component. In this case, a problem of reduced strength may occur.

The anhydrous gypsum functions to improve the adhesion of the first coating layer 710 by increasing the viscosity, and the anhydrous gypsum serves to improve the adhesion when mixing the powder component and the liquid component. The mixture of dihydrate gypsum and anhydrous gypsum is preferably contained in the range of 1 to 10 parts by weight based on 100 parts by weight of the resin composition. If the content is less than 1 part by weight, viscosity and adhesion decrease, and if it exceeds 10 parts by weight, If this happens, problems such as decreased strength or chemical resistance may occur.

The plaster also plays a role in allowing powder components and liquid components to be easily mixed. It is preferably contained in the range of 1 to 10 parts by weight based on 100 parts by weight of the resin composition, and the content of the plaster is 1. If it is less than 10 parts by weight, there is a problem that various components included in the powder component are difficult to mix with the liquid component, and if it exceeds 10 parts by weight, problems such as deterioration in strength and chemical resistance may occur.

The silica fume is an amorphous active silica with an average particle diameter of about 0.15㎛ and is characterized by particles that are close to perfectly spherical shapes. Due to the characteristics of spherical particles, silica fume is formed by the filling effect between powder component particles. It improves water resistance and chemical resistance, and also plays a role in improving the strength of the coating agent or the adhesion performance of the coating layer. The silica fume is preferably contained in the range of 1 to 5 parts by weight based on 100 parts by weight of the resin composition. If the content is less than 1 part by weight, the water resistance and chemical resistance of the first coating layer 710 are reduced and the strength is reduced. There is a problem of lowering, and if it exceeds 5 parts by weight, problems such as cracks may occur.
