Description

Technology Field

[0001] The present invention relates to an eco-friendly insulation structure for multi-unit residential buildings within the field of construction technology. More specifically, it relates to an improved eco-friendly insulation structure for multi-unit residential buildings that possesses excellent thermal insulation and heat shielding performance as well as heat resistance and fire resistance, thereby preventing the rise in indoor temperature caused by the urban heat island effect, and enhancing the effect of blocking the spread of fire from the exterior wall upward through window frames by inserting and installing fire extinguishing agents between the insulation materials. Background Technology

[0002] Recently, due to factors such as shortened construction time, lighter structures, and a shortage of skilled construction personnel, the use of lightweight wall systems that have transitioned from wet construction methods to dry construction methods is increasing in construction projects.

[0003] Sandwich panels, EPS cement composite panels, ALC panels, or gypsum board composite panels are used as dry-processed lightweight wall systems.

[0004] Among these, Korean Patent Application No. 10-2003-0030116 (Composition of a lightweight panel with superimposed hollow synthetic resin corrugated cardboard and method of manufacturing the same) involves bonding an exterior panel made of aluminum foil or color steel plate with several pieces of synthetic resin corrugated cardboard having multiple grid-like hollow sections, or bonding an insulating material between the synthetic resin corrugated cardboards as an adhesive layer, and then compressing and curing it with a high-pressure press to complete the panel. This method mutually compensates for the weaknesses of the synthetic resin corrugated cardboard, insulating material, and exterior panel, thereby providing a panel that is lightweight, has excellent mechanical strength, and superior thermal insulation. Furthermore, it offers various benefits, such as a relatively simple composition and manufacturing process that allows for widespread supply at a low production cost.

[0005] However, the lightweight panel according to the above-mentioned Korean patent application No. 10-2003-0030116 had a problem in that its water resistance was very poor because it was made of corrugated cardboard.

[0006] In addition, Korean Patent Application No. 10-2005-0083751 (Method for manufacturing an eco-friendly lightweight sandwich building panel) provides an eco-friendly sandwich panel in which an insulating member is formed in the center and metal plates are attached to both sides, wherein the insulating member is formed by mixing one-year-old hay cut to a certain size with a plant-based adhesive material, and the method for manufacturing an eco-friendly lightweight sandwich building panel comprises a series of processes including a hay drying process for removing moisture from the one-year-old hay, a cutting process for cutting it to a certain size, a mixing process for adding and mixing a plant-based adhesive material to the cut hay, a molding process for compressing and molding the mixed material into a certain shape, a drying process for drying the molded insulating member, and an assembly process for attaching metal plates to both sides of the dried insulating member.

[0007] However, the lightweight sandwich building panel according to Korean patent application No. 10-2005-0083751 had the problem that the construction process was very complex and it was vulnerable to heat because it was made of hay.

[0008] Meanwhile, Korean Utility Model Registration Application No. 20-2009-0014435 (Loess Board and Electric Ondol Panel Device Using the Same) describes an electric ondol panel device combining a loess board, loess fibers, and a carbon-containing heating wire. It further states that the panel device is effective for anti-aging, promoting blood circulation, relieving stress, improving skin, treating neuralgia and back pain, recovering from chronic fatigue, and treating atopic dermatitis through far-infrared radiation, and that it can also be used as a substitute for a finishing material, thus being effective for cost reduction.

[0009] However, in Korean Utility Model Registration Application No. 20-2009-0014435, the loess board is composed of 40% by weight of loess, 30% by weight of magnesium oxide, 15% by weight of biotite, and a magnesium chloride solution, so there was a concern about increased costs, as well as a problem that the manufacturing process of the loess board and the electric underfloor heating panel device using the loess board is complex.

[0010] In addition, while conventional sandwich panels and EPS cement composite panels offer excellent thermal insulation performance, they are highly vulnerable to high temperatures and pose a risk of casualties due to severe toxic gas emissions in the event of a fire.

[0011] In addition, while conventional ALC panels and gypsum board composite panels are lightweight and possess excellent fire resistance, they have poor water resistance, raising concerns about damage from water leakage; furthermore, they are prone to breakage due to low strength; and they also have the problem of increased manufacturing costs due to very high energy consumption during production.

[0012] In addition, while cement-based dry panels are non-combustible and possess excellent strength and water resistance, they are based on cement, a major source of CO2 emissions, and require a separate high-temperature curing process to ensure productivity, which poses a problem of significantly increased production costs.

[0013] As part of efforts to improve this, Registered Patent No. 1347210 (December 26, 2013), titled "Lightweight wall system using eco-friendly high-strength lightweight fire-resistant insulation panel composition and method of construction thereof," is disclosed, but further reinforcement is required in terms of fire resistance.

[0014] In addition, worsening weather conditions caused by increasingly severe global warming are accelerating the urban heat island effect during the hottest months and sustaining severe cold during the coldest months, so there is a need for further reinforcement in terms of insulation and heat shielding. The problem to be solved

[0015] The present invention was created to solve the various problems of the prior art described above, and its main purpose is to provide an improved eco-friendly insulation structure for multi-unit residential buildings that possesses excellent thermal insulation and heat shielding performance as well as heat resistance and fire resistance, thereby preventing the rise in indoor temperature caused by the urban heat island effect, and enhancing the effect of blocking the spread of fire upwards along the exterior wall through window frames in the event of a fire by inserting fire extinguishing agents between the insulation materials. means of solving the problem

[0016] The present invention provides an eco-friendly insulation structure for a multi-unit building, characterized in that, as a means to achieve the above-mentioned purpose, an insulation material (30) is interposed between an outer wall (10) and a finishing board (20), a heat-insulating material (40) is further interposed between the insulation material (30) and the finishing board (20), and a groove is formed in a part of the insulation material (30) and a fire-extinguishing material (50) is embedded within the groove. Effects of the invention

[0017] According to the present invention, not only is it possible to secure high strength and high fluidity, but also excellent fire resistance (non-combustibility) and water resistance due to the formation of regular bubbles within itself and a coating film on the surface of the matrix, and accordingly, it is possible to shorten the production period by securing fluidity and achieving early strength, and excellent constructability can be obtained by exhibiting lightweight properties. Brief explanation of the drawing

[0018] FIG. 1 is an exemplary diagram showing the structure of an insulating material according to the present invention. Specific details for implementing the invention

[0019] Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the attached drawings.

[0020] Prior to describing the present invention, the following specific structural or functional descriptions are provided merely for the purpose of illustrating embodiments according to the concept of the present invention. Embodiments according to the concept of the present invention may be implemented in various forms and should not be interpreted as being limited to the embodiments described herein.

[0021] In addition, since embodiments according to the concept of the present invention may be subject to various modifications and may take various forms, specific embodiments are illustrated in the drawings and described in detail in this specification. However, this is not intended to limit the embodiments according to the concept of the present invention to specific disclosed forms, and it should be understood that they include all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention.

[0022] As illustrated in FIG. 1, the eco-friendly insulation structure of a multi-unit building according to the present invention has an insulation material (30) interposed between an outer wall (10) and a finishing board (20), a heat shielding material (40) further interposed between the insulation material (30) and the finishing board (20), and has a shape in which a groove is formed in a part of the insulation material (30) and a fire extinguishing material (50) is embedded in the groove.

[0023] At this time, the outer wall (10) is a concrete structure and is composed of 2.5-5.0% by weight of trimellitic anhydride, 15-20% by weight of cement, 2.5-5.0% by weight of Dichan, 25-30% by weight of sand, 20-25% by weight of gravel and the remainder of water to help suppress the heat island effect and enhance neutralization prevention properties.

[0024] Here, trimellitic anhydride contributes to enhancing waterproofing and insulation functions, thereby helping to suppress the urban heat island effect.

[0025] In addition, Dichan is Dicyclohexyleammonium Nitrite, with the chemical formula (C6H 10 It is represented as )2ㆍNH3HNO2 and forms a thin protective layer on metals such as iron, and through this protective layer, blocks oxygen, moisture, or oxidizing substances from reacting with the metal surface, thereby preventing corrosion and contributing to the inhibition of concrete neutralization.

[0026] In addition, the above finishing board (20) is manufactured by mixing 55 parts by weight of magnesium oxide, 2 parts by weight of acetic acid, 10 parts by weight of pyromellitic acid, 20 parts by weight of stone powder, and 10 parts by weight of methyl salicylate with respect to 100 parts by weight of water, then placing the mixture into a mold and molding it.

[0027] The finishing board (20) manufactured in this way is lighter than a conventional aluminum plate and is advantageous for water resistance, water resistance, and high strength, and above all, can be manufactured at a low cost.

[0028] In this case, magnesium oxide has excellent crack inhibition capabilities and contributes to strengthening durability.

[0029] In addition, acetic acid induces crystallization, thereby enhancing water resistance.

[0030] In addition, pyromellitic acid is added to inhibit heat shrinkage and enhance slip properties, thereby improving moldability during raw material molding and increasing durability.

[0031] In addition, stone powder densifies the structure through the pozzolanic reaction, contributing to the development of strength and improved durability.

[0032] In addition, methyl salicylate is a colorless liquid with a specific gravity of 1.18, a boiling point of 223°C, and a melting point of -9°C, which contributes to enhancing cold resistance, salt resistance, and water resistance.

[0033] Meanwhile, the above-mentioned thermal insulation material (40) is used by mixing 4.5 parts by weight of methylsilsequioxane, 6.5 parts by weight of Sb2O3, 3.5 parts by weight of propylene dicarboxylic acid, 5.5 parts by weight of lithium silicate, 5.5 parts by weight of PBAT (Poly-Butylene Adipate Terephthalate), and 1.5 parts by weight of a foaming agent with respect to 100 parts by weight of low-density polyethylene resin, and then foaming the mixture in a mold to produce a foam-like material.

[0034] At this time, methylsilsecquioxane is added to increase the contact angle by inducing nano-sized micropores on the surface through reaction with silane groups, thereby increasing surface roughness and thereby enhancing water resistance, or water repellency.

[0035] In addition, Sb2O3 is an inorganic flame retardant.

[0036] In addition, propylene dicarboxylic acid is added to increase inter-particle dispersion stability and storage stability on the particle surface of the polymerized polymer, thereby suppressing crack formation and contributing to enhanced thermal insulation function.

[0037] In addition, lithium silicate enhances water resistance and heat insulation, and contributes to stain resistance.

[0038] Furthermore, PBAT (Poly-Butylene Adipate Terephthalate) increases elongation, ensuring flexibility, processability, and durability.

[0039] On the other hand, the above-mentioned finishing board (20) is firmly fixed to the outer wall (10) through a fixing bracket (60).

[0040] That is, one end of the above-mentioned fixed bracket (60) is anchored to the outer wall (10), and the other end is connected to the finishing board (20) through the connector (70).

[0041] At this time, the foam-shaped thermal insulation material (40) is interposed between the insulation material (30) and the finishing board (20) and compressed by the finishing board (20), thereby filling the empty space between the finishing board (20) and the insulation material (30) thoroughly and eliminating lifting, thereby further enhancing the thermal insulation performance and improving fixing stability.

[0042] Additionally, the above fire extinguishing agent (50) refers to a fire extinguishing agent and has a structure in which the fire extinguishing agent is packaged in a thin synthetic resin housing, that is, a vinyl packaging.

[0043] The reason for packaging fire extinguishing agents in plastic wrap like this is to allow the wrapper to easily melt due to heat in the event of a fire, thereby releasing the agent.

[0044] That is, the finishing boards (20) are of a certain size and are installed in a grid pattern with a few pieces spaced apart. At this time, the fire extinguishing agent (50) is heated when flames rise out of the building through the window frame due to a fire, and the fire extinguishing agent (50) embedded inside bursts and flows out through the gaps between the finishing boards (20), thereby preventing the flames from spreading.

[0045] As such, the present invention provides excellent heat resistance, fire resistance, as well as thermal insulation and heat shielding performance, thereby preventing the rise in indoor temperature of multi-unit residential buildings due to the heat island effect. Furthermore, by inserting and installing fire extinguishing agents between the insulation materials, it becomes possible to enhance the effect of blocking the spread of fire upwards along the exterior wall through the window frame in the event of a fire.
