Description

High-insulation wall panels for construction

[0001] The present invention relates to a high-insulation wall panel for construction installed on a structural wall of a building, and more specifically, to a high-insulation wall panel for construction that improves upon the existing practice of using wooden bars or FRP bars alone as structural bars by using stainless steel pipes alone or in combination with stainless steel pipes and GFRP bars as structural bars, thereby further reducing heat loss and forming a structurally strong connection compared to the past.

[0002]

[0003] Insulation methods for blocking heat in buildings include external, intermediate, and internal insulation, based on the wall. Furthermore, the core of insulation methods is not only insulation performance, but also how to secure and connect the structure, insulation, and finishing materials to safely protect the insulation from external factors such as fire and earthquakes. Various materials and methods have been developed based on this understanding.

[0004] However, the reality is that the development of materials and construction methods that can perfectly respond to external forces such as earthquakes and ensure safety against fire has not progressed satisfactorily to date.

[0005] The first important factor that determines the insulation performance of a building is the type and thickness of the insulation, and the second is the thermal bridge phenomenon in which heat escapes due to the material or method of fixing the insulation. Therefore, good insulation and construction without thermal bridges are important factors.

[0006] In addition, among the insulation methods, it is already recognized that the most efficient method among internal, intermediate, and external insulation is the external insulation method, and the external insulation method is being promoted, but most of the external insulation construction methods currently being implemented are adhesive-attached insulation materials, and many problems are occurring in that the insulation materials cannot be safely protected from fire due to the weight of the finishing material, which is a limitation of this method.

[0007] That is, in the case of external insulation, it is difficult to finish the insulation material to protect it from fire by attaching it with adhesive force, and conversely, when finishing with thick non-combustible material to ensure fire safety, there is a problem of reduced insulation performance due to thermal bridges caused by hardware used to fix it to the wall.

[0008] The best insulation method is the external insulation method, which is fire-resistant, allows the use of finishing materials regardless of weight, and is also resistant to earthquakes and typhoons. However, an insulation panel that satisfies this has not been developed yet.

[0009] In order to solve this problem, the applicant of the present invention, in Patent Registration No. 10-2173559, proposed an architectural insulation panel that not only achieves optimal structural stability while allowing easy construction through angles on the wall of a building by placing a structural frame on each side of the insulation and structural rods made of FRP or wooden rods penetrating the inside of the insulation to form a truss structure and fixing both ends of the structural rods to the structural frame, but also allows construction and installation of various finishing materials on the outside without being affected by the weight of the finishing materials.

[0010] The applicant was not satisfied with this and continued research and development on heat loss and structural rigidity of insulating panels, and came up with the present invention as a solution to the problems of the prior art.

[0011]

[0012] <Prior art literature>

[0013] Registered Patent No. 10-2173559

[0014]

[0015] The purpose of the present invention is to solve the problems of the prior art described above, and to provide a high-insulation wall panel for construction having an improved form that improves insulation by using a stainless steel pipe alone or a combination of a stainless steel pipe and a GFRP rod as a structural rod that connects a structural frame and an insulation material, while improving the existing use of a wooden rod or an FRP rod alone, thereby further minimizing heat loss while maintaining structural strength.

[0016] However, the purpose of the present invention is not limited thereto, and it is obvious that the purpose or effect that can be understood from the solution or embodiment of the problem even if not explicitly mentioned is also included.

[0017]

[0018] In order to achieve the above-described purpose, the present invention provides a high-insulation wall panel for construction, comprising: an insulating material; a structural frame that is closely arranged on one or both sides of the insulating material; and a structural rod that penetrates the insulating material in the width direction and has its end fixed to the structural frame. The structural rod is characterized in that it is formed of a stainless steel pipe in the form of a hollow tube made of stainless steel to reduce heat loss due to heat transfer while maintaining structural strength.

[0019] The above stainless steel pipe may have a diameter of 12 to 15 mm and a thickness of 0.3 to 0.5 mm.

[0020] The above structural bar can be configured by dividing the stainless steel pipe into two parts on both sides and connecting the stainless steel pipes divided into two parts on both sides with a GFRP (glass fiber-reinforced plastic) bar.

[0021] The above stainless steel pipe and the GFRP rod can be configured to be connected by inserting an end of the GFRP rod into one side of the stainless steel pipe and using a connecting means including a bolt and a nut.

[0022] The above insulation material can be configured to have a width and thickness of 350 mm or more in order to implement a high-insulation wall panel for construction with an insulation performance of a thermal transmittance of 0.1 W / m2k or less.

[0023] It may be configured to further include a finishing board fixedly installed on the outside of the above structural frame.

[0024]

[0025] According to the above, the high-insulation wall panel for construction of the present invention improves upon the existing wall panel that used only FRP or wooden rods as structural rods by using stainless steel pipes or a combination of stainless steel pipes and GFRP rods, thereby further reducing heat loss due to heat transfer while maintaining a satisfactory level of structural strength, thereby lowering thermal conductivity, and thus can be usefully used as an essential material for high-insulation buildings such as passive houses and zero-energy buildings.

However, readers with sufficient knowledge of the field to understand the present invention will recognize that the present invention can be used without these specific details. In some cases, it is noted in advance that commonly known but largely unrelated aspects of the invention have been omitted to avoid unnecessary confusion in the description of the invention.

[0041] Hereinafter, with reference to FIG. 1, a high-insulation wall panel (1) for construction according to a first embodiment of the present invention will be described.

[0042] The high-insulation wall panel (1) for construction of the present invention is configured to include an insulating material (10), a structural frame (20), a finishing board (30, 31), and a structural bar (40).

[0043] The high-insulation wall panel (1) for construction of the present invention is configured to include an insulating material (10), a structural frame (20), a finishing board (30, 31), and a structural bar (40).

[0044] The insulation material (10) is configured such that an organic insulating material in a foam form with excellent insulation performance and an inorganic insulating material such as glass fiber wool or rock wool that is fire-resistant and non-combustible are overlapped on the outer surface of the organic insulating material. However, the present invention is not limited thereto, and the insulation material (10) may be configured only with the organic insulating material or only with the inorganic insulating material. In addition, the insulation material may be configured such that an inorganic insulating material is overlapped on both sides of the organic insulating material, and in addition, the insulation material may be configured such that the organic insulating material and the inorganic insulating material are laminated in various arrangements.

[0045] In the present invention, the insulation material (10) is preferably designed to have a thickness of 350 mm or more in order to implement a high-insulation wall panel for construction having an insulation performance of a thermal transmittance of 0.1 W / m2k or less.

[0046] The structural frame (20) is made of steel pipes such as iron or aluminum in the form of a square frame or a lattice frame, and is installed in close contact with both sides of the insulation material (10) as shown in Fig. 1.

[0047] However, although not shown, the structural frame (20) may be configured to be in close contact with only one side of the insulation (10).

[0048] The finishing board (30, 31) is composed of a flame-retardant board such as an asbestos-free high-density fiber-reinforced cement board (cellulose reinforced cement board, hereinafter referred to as 'CRC board'), and is configured to be installed by being joined to the structural frame (20) using a fastening means such as a piece (screw).

[0049] Although not shown, if the structural frame (20) is formed on only one side of the insulation material (10), the finishing board (30) will be installed only on the structural frame (20) formed on one side of the insulation material (10), and if the structural frame (20) is formed on both sides of the insulation material (10) as shown in FIG. 2, the finishing boards (30, 31) are respectively combined and formed on each structural frame (20).

[0050] The structural bar (40) is a component representing the main feature of the present invention, and penetrates the insulating material (10) having a thickness of 350 mm or more, and both ends protruding from the insulating material (10) are fixedly connected to the structural frames (20) on both sides.

[0051] When constructing a high-insulation wall panel, if an insulation material (10) of 350 mm or more is constructed to achieve high-insulation performance with a thermal transmittance of 0.1 W / m2k or less, there is a risk of fire if the structural frame (20) and the insulation material (10) are simply bonded with an adhesive, and there are problems such as the insulation material (10) being easily peeled off from the structural frame (20) due to external forces such as a typhoon.

[0052] Accordingly, the structural bar (40) is fixed to the structural frame (20) by penetrating the insulating material (10) to provide a strong bonding structure between the insulating material (10) and the structural frame (20). However, in the applicant's previously registered patent No. 10-2173559, although heat loss was greatly reduced by using an FRP bar or a wooden bar as the structural bar, there was some regret that the structural strength did not reach a satisfactory level.

[0053] Accordingly, the present invention configures the structural bar (40) with a stainless steel material, which is a metal material, to maintain structural strength, but configures it with a stainless steel pipe in the form of a hollow tube to reduce heat transfer rate and prevent heat loss.

[0054] That is, the present invention can maintain good strength while reducing heat transfer through a reduction in cross-sectional area by configuring the structural bar (40) as a stainless steel pipe with an empty interior.

[0055] In other words, if the structural bar (40) is simply composed of a generally filled stainless steel bar, the structural strength can be significantly increased, but the heat transfer rate is high, resulting in a large amount of heat loss due to heat transfer. Accordingly, the present invention constructs the structural bar (40) from a stainless steel pipe with a hollow interior and thus a reduced cross-sectional area, thereby maintaining a satisfactory level of structural strength while drastically reducing heat transfer.

[0056] Preferably, the structural bar (40) of the present invention is configured as a stainless steel pipe having an internal hollow tube shape in order to reduce heat transfer by reducing the cross-sectional area while maintaining strength. The stainless steel pipe is preferably configured with a diameter (outer diameter) of 12 to 15 mm and a pipe thickness of 0.3 to 0.5 mm.

[0057] When the diameter of the stainless steel pipe is less than 12 mm, it is easy to penetrate the insulation (10), but there is a problem that the strength of the wall panel is reduced and structural stabilization is difficult to achieve. When the diameter of the stainless steel pipe is more than 15 mm, it is difficult to penetrate the insulation (10), and although the strength of the wall panel is increased, there is a problem that the heat transfer rate is increased and the insulation is poor.

[0058] In addition, when the thickness of the stainless steel pipe is less than 0.3 mm, the heat transfer rate is low, but the structural strength is low, and when it exceeds 0.5 mm, the structural strength is good, but the heat transfer rate is high, so there is a problem that heat loss increases excessively.

[0059]

[0060] Hereinafter, with reference to FIGS. 2 to 4, a high-insulation wall panel (1') for construction according to a second embodiment of the present invention will be described.

[0061] In the first embodiment, the structural bar (40) was composed of a single stainless steel pipe, but in the second embodiment, the stainless steel pipe (43) is divided into two parts on both sides, and the stainless steel pipes (43) on both sides are connected with a GFRP (glass fiber-reinforced plastic) bar (41), thereby further blocking heat transfer through the stainless steel pipe (43) and further minimizing heat loss.

[0062] That is, in the applicant's previously registered patent, Patent No. 10-2173559, an FRP rod or a wooden rod was used alone, but the structural rod (40) in the second embodiment is not composed of a single member alone, but is composed of a combination of a GFRP rod (41) made of GFRP (glass fiber-reinforced plastic) material and a stainless steel pipe (43) made of stainless steel material, thereby maintaining the structural strength of the insulating wall while further reducing heat loss and improving the insulating properties.

[0063] The structural bar (40) is configured to penetrate the insulation (10) in the width direction and have an end protruding outward from the insulation (10), and the end protruding outward from the insulation (10) is configured to be connected to the structural frame (20).

[0064] In the present invention, the structural bar (40) is configured with a GFRP bar (41) formed in the middle of the length, and stainless steel pipes (43) are connected to both ends thereof.

[0065] It is configured so that the ends of the stainless steel pipes (43) on both sides are joined to the structural frame (20), and a GFRP rod (41) is joined between the stainless steel pipes (43) on both sides to block heat transfer.

[0066] The GFRP rod (41) is inserted into the end of a stainless steel pipe (43) and is configured to be joined by a joining means (45) such as a bolt or nut.

[0067] Referring to FIGS. 3 and 4, a bolt pass-through hole (h1) is formed on the upper and lower sides of one end of a stainless steel pipe (43), and a bolt pass-through hole (h2) is formed on the end of a GFRP rod (41). By inserting the end of the GFRP rod (41) into the inside of the end of the stainless steel pipe (43) and matching the bolt pass-through holes (h1, h2) with each other, passing a bolt (45) through it, and tightening it with a nut (45a), the end of the GFRP rod (41) and the end of the stainless steel pipe (43) can be connected to each other.

[0068] Meanwhile, the present invention can improve the bonding property by applying an adhesive (46) to the outer surface of the end of the GFRP rod (41) or the inner surface of the end of the stainless steel pipe (43) before inserting the end of the GFRP rod (41) into the stainless steel pipe (43), inserting the end of the GFRP rod (41) into the stainless steel pipe (43) so that the end of the GFRP rod (41) is first bonded to the end of the stainless steel pipe (43) by the adhesive (46), and then passing the bolt (45) through the bolt through hole (h1, h2) and fastening it with a nut (45a) so that the second bonding is achieved by the bolt nut.

[0069] In this embodiment, both ends of the structural bar (40), that is, the ends of each stainless steel pipe (43) on both sides, can be connected to the structural frame (20) in various ways.

[0070] The end of the stainless steel pipe (43) can be joined to the structural frame (20) using an adhesive. In addition, the end of the stainless steel pipe (43) can also be joined to the structural frame (20) by welding.

[0071] In addition, referring to FIGS. 5 and 6, the end of the stainless steel pipe (43) can be configured to be fixedly connected to the structural frame (20) by a fixing member (51).

[0072] After applying adhesive to the inner surface of the fitting groove (51a) of the fixed hardware (51), the outer end of the stainless steel pipe (43) is inserted into the fitting groove (51a) and bonded, and then the fixed hardware (51) can be connected to the structural frame (20) using a fastening member such as a screw (s).

[0073] In the present invention, the structural bar (40) is configured in multiple pieces, and penetrates the insulation material (30) at various angles or horizontally, and each of the two ends is fixedly connected to the structural frame (20), thereby forming a truss structure with the multiple structural bars (40) to achieve structural stability.

[0074] The structural bar (40) of the present invention was evaluated to have a breaking strength of 1000 kg or more in a strength test, and the high-insulation wall panel for construction of the present invention is 1 m thick, so as to maintain good structural strength without any problems. 2 It is desirable to configure it so that more than 20 structural bars (40) are placed.

Rather, those skilled in the art will readily appreciate that numerous modifications and variations are possible without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate modifications and variations, as well as their equivalents, should be considered within the scope of the present invention.
