Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum insulated panel,

The following embodiment relates to a vacuum insulation panel using a cut-out structure.

As the minimization of environmental costs becomes an important issue for enterprises and countries, energy efficient design for all buildings is indispensable. Currently, the requirements for energy conservation such as eco-friendly building certification and energy efficiency grade certification are strengthened in the construction of buildings.

When cooling and heating is performed inside the building, much of the energy loss is made through the exterior of the building. Therefore, the method of insulating the exterior of a building is being treated with great weight in relation to energy saving. For example, insulation of a building envelope can save more than 50% of the energy loss of a building.

Conventionally, polyurethane, styrofoam, glass fiber or the like has been used as a general material used as a thermal insulation material of a building. Then, a vacuum insulation panel (VIP) having excellent heat insulation performance has been developed. However, vacuum insulation panels with aluminum foil and vinyl sheaths are very difficult to apply to construction areas due to various problems. Vacuum insulation using metal or plastic panels has been devised.

Vacuum thermal insulation panels using metal and plastic panels minimize the heat transfer through conduction and convection by forming a vacuum space between a pair of panels. However, when a vacuum space is formed between the pair of panels, the panel is pressed inward due to the atmospheric pressure, causing a problem that the vacuum part having heat insulating performance is disappeared. In order to maintain the vacuum space, Core material shall be installed. In this case, heat transfer through the core material occurs, so that there is a problem in that effective insulation is not achieved depending on the material quality or shape of the core material.

Accordingly, there is a demand for a structure of a vacuum insulation panel having high durability while effectively performing heat insulation

The background art described above is possessed or acquired by the inventor in the derivation process of the present invention, and can not be said to be a known art disclosed in general public before application of the present invention.

An object of one embodiment is to provide a vacuum insulating panel having a high durability and a high heat insulating property by using the cut-away structure.

It is an object of one embodiment to provide a vacuum adiabatic panel having a structure for efficiently sealing a vacuum space.

A vacuum insulation panel installed on a building according to an embodiment includes a pair of panel plates spaced apart from each other to form a vacuum space for heat insulation; A cutout plate including a cut-out core member in which a bone and an acid are repeatedly formed, the cutout plate being inserted into the vacuum space; And a sealing part interposed in close contact with an outer periphery of the pair of plates.

The cut-off plate may further include an outer support wall adhered to an end of the cut-out core so as to be perpendicular to the longitudinal direction of the valley.

The cut-away core may be divided perpendicularly to the longitudinal direction of the valley, and the cut-out plate may further include an inner support wall which is bonded between the cut-out core pieces.

The plurality of cut-out plates may be stacked in such a manner that the plurality of cut-out plates are stacked in the same direction with each other, and the bones and the acid are in contact with each other between the adjacent cut-out plates.

The plurality of cut-out plates may be stacked such that longitudinal directions of the plurality of cut-out plates perpendicularly cross each other between adjacent cut-out plates.

The pair of panel plates may be formed so that the outer frame is bent so that the curved outer frame faces the mutually facing directions.

As the vacuum is formed in the vacuum space, the sealing portion may be closely attached to the panel plate so as to surround the inner and outer surfaces of the bent outer edge.

Further comprising a reinforcing support body having both ends connected to an inner surface of the pair of panel plates, wherein the reinforcing support body is installed in the vacuum space so as to penetrate the cutout plate.

Wherein the reinforcing supporter comprises: a pair of column bases connected to inner surfaces of the pair of panel plates; And a plurality of support columns connecting the pair of column supports, wherein the plurality of support columns may be radially arranged along a circumferential direction with respect to a center of the column support.

The distance from the center of each of the pair of column supports to the point where the support pillars are connected to the pair of column supports may be different from each other.

In the drawings, it is noted that the transparently processed portion is processed to be transparent in order to express the internal structure and does not mean that the portion is a transparent material.

1 to 3, the vacuum insulation panel 1 according to one embodiment may be installed in a curtain wall of a building. Generally, the floor and ceiling of a building are formed through a slab having a flat plate shape. Thus, each layer of the building can be formed through the space between the slabs. The curtain wall is installed on the outside of the building, for example, on the slab, thereby forming the appearance of the building. The curtain wall includes a mullion having a longitudinal direction perpendicular to the ground and a transom having a horizontal longitudinal direction, wherein the plurality of mullions and transoms are spaced apart from each other, Into a unit space. A panel or a glass member is installed in the space partitioned by the mullion and the transom to form a unit outer wall of the building. In this case, the unit outer wall on which the panel is installed forms a nonvision part that does not transmit light, and the unit outer wall on which the transparent glass member is mounted is a vision part through which light is transmitted. . As a result, most of the heat transfer between the interior and the exterior of the building is performed through the exterior wall of the building.

The vacuum insulated panel 1 according to one embodiment can be formed in the above-described curtain wall to form an outer wall of the building. The vacuum heat insulating panel 1 can increase the heat insulating effect of the panel by forming a vacuum space therein. The vacuum insulated panel 1 according to one embodiment may include a panel plate 11, a sealing portion 12, and a plate plate 13.

The panel plate 11 can constitute the outer surface of the vacuum heat-insulating panel 1. The panel plates 11 may be arranged in pairs so as to face the inside and the outside of the building, respectively. The panel plate 11 may be formed to have a rectangular plate shape. The pair of panel plates 11 can be disposed apart from each other to form a vacuum space for insulation. In the drawing, the panel plates 11 are formed as a pair to form one vacuum space. Alternatively, a plurality of panel plates 11 may be provided so as to be spaced apart from each other, thereby forming a plurality of vacuum spaces. Hereinafter, for convenience of explanation, a case where the panel plates 11 are provided as a pair will be exemplarily described.

When a pair of panel plates 11 are spaced apart from each other, a vacuum space may be formed between the pair of panel plates 11. [ In this case, since the contact between the pair of panel plates 11 is blocked with the vacuum space as a boundary, the heat transfer due to the conduction phenomenon is prevented and the heat transfer due to the convection phenomenon is further prevented through the internal vacuum . In other words, since the heat transfer path is blocked through the vacuum space, the high thermal insulation property of the vacuum insulating panel 1 can be ensured.

The sealing portion 12 can seal the vacuum space so that the vacuum state of the vacuum space is maintained. The sealing portion 12 can be interposed so as to be in close contact with the respective panel plates 11 along the outline of the pair of panel plates 11. [ The sealing portion 12 may be formed to surround the outer surface of the panel plate 11. It should be noted that the shape of the sealing portion 12 shown in Figs. 1 and 2 is schematically shown. The sealing portion 12 can be connected to the inner surface of the panel plate 11 in a completely tight manner by including a rubber material. The sealing portion 12 can be pressed and coupled to the outer periphery of the pair of panel plates 11 by a negative pressure generated as a vacuum is formed in the vacuum space. For example, the sealing portion 12 is partially sucked into the vacuum space or the like due to a negative pressure, and thus the shape of the sealing portion 12 is deformed to strongly bind to the outer periphery of the pair of panel plates 11. [ . The sealing portion 12 can block the inflow of air into the vacuum space between the panel plates 11. The details will be described later. On the other hand, the sealing portion 12 may be connected to the panel plate 11 by an adhesive or the like.

By inserting the cutout plate 13 into the vacuum space, the durability of the vacuum thermal insulating panel 1 can be reinforced. When a vacuum space is formed between the pair of panel plates 11, due to the atmospheric pressure outside the vacuum insulation panel 1, the pair of panel plates 11 are subjected to continuous pressure in the vacuum space direction. If a constant pressure is applied to the pair of panel plates 11, the pair of panel plates 11 may be deformed to warp in the vacuum direction. The cut-out plate 13 supports the pair of panel plates 11, so that the pair of panel plates 11 can be reinforced so as not to be bent in the vacuum direction. That is, the cut-out plate 13 can prevent the pair of panel plates 11 from being deformed by the negative pressure according to the vacuum. The cutout plate 13 may include a cutout core 131, a support plate 132, an outer support wall 133 and an inner support wall 134. [

The cut-out core member 131 may be formed in a cut-out structure. The out-of-plane structure may refer to a structure in which a bone and an acid are repeatedly formed. The goal means the lowest point, and the mountain can mean the peak. The bones and the mountains may be formed in the longitudinal direction. The bone and the acid can extend parallel to each other. The trimming core 131 may be formed in a structure in which a triangular shape is repeatedly bent repeatedly at an angle as shown in FIG. 2, or a structure in which a wavy shape is repeatedly curved smoothly. Since the cut-out structure has high durability in the vertical direction, it can effectively resist against the vertical pressure. Therefore, by using the cut-out plate 13 having a cut-away structure, it is possible to efficiently provide the pair of panel plates 11 with a compressive strength. The cutout plate 13 inserted in the vacuum space can resist a deformation force that the pair of panel plates 11 is bent in the vacuum space direction by the negative pressure in the vacuum space. The lengths (pitches of the bones) and the height of the bones and the mountains of the bobbin trimming material 131 repeatedly appearing may be variously formed according to the purposes and applications of the vacuum thermal insulation panel 1. [ On the other hand, the trimming core 131 can be divided perpendicularly to the longitudinal direction of the ridge. That is, the trimming core 131 may be composed of a plurality of divided core members 1311 which are divided perpendicularly to the longitudinal direction of the crest. The cut-out core member 131 can be divided equally. That is, the divided core members 1311 may be formed to have the same length.

The support plate 132 can support the lower side of the cutout core member 131. The support plate 132 may be adhered to the crest or the mountain of the trimming core 131. [ The support plate 132 may be formed in a rectangular plate shape. The support plate 132 may be positioned between one corrugated core 131 and the other corrugated core 131 so as to form the boundary between the corrugated core 131 when a plurality of the plate plates 13 are stacked. On the other hand, in the case of the cutout plate 13 disposed at the uppermost or lowermost end in the vacuum space, it may not include the support plate 132. For example, in the case of Fig. 2, the cut-out plate 13c disposed at the lowermost end in the vacuum space may not include the support plate.

The outer support wall 133 can support the cut-out core 131 from the outside. The outer support wall 133 can be adhered to the end of the cut-off core 131 so as to be perpendicular to the longitudinal direction of the valley. The outer support wall 133 is bonded to the both ends of the cut-away core member 131 in the longitudinal direction of the valley, thereby preventing the cut-out core member 131 from being deformed. When a strong deformation force acts on the panel plate 11, it is possible that the cut-out core member 131 can not stand the deforming force sufficiently and collapse. In order to prevent this, the outer support walls 133 are adhered to both end portions of the cut-off core 131, so that deformation of the cut-out core 131 can be suppressed. The outer support wall 133 can strengthen the stiffness of the cutout core 131. [ According to this structure, deformation of the pair of panel plates 11 can be more firmly prevented.

The inner support wall 134 can be inserted and adhered between the partitioned core members 131. [ That is, the inner support wall 134 is inserted between the partition core members 1311, and both sides thereof can be bonded to the adjacent partition core members 1311, respectively. The inner support wall 134 can suppress the deformation of the cutoff core 131 similarly to the outer support wall 133. [ According to the structure in which the cut-away core member 131 is divided into a plurality of divided core members 1311 and the inner support wall 134 is adhered therebetween, the inner support wall 134 is positioned in the middle of the cut core member 131 Since the deformation of the trimming core 131 is prevented, the strength of the trimming core 131 can be further strengthened. Further, since the divided core 1311 is divided into a plurality of pieces, the torsion acting on the cut core 131 can be prevented more efficiently. A plurality of inner support walls 134 may be provided. The inner support walls 134 may be equally spaced with respect to the longitudinal direction of the valleys in the trimming core 131. For this purpose, the trimming core 131 may be divided equidistantly perpendicularly to the longitudinal direction of the crest. 1 and 2 illustrate that the cut core 131 is divided into three split core members 1311 and two inner support walls 134 are inserted therein. May be divided into various lengths and numbers, so that the inner support wall 134 may also be provided in various numbers.

Referring to FIGS. 1 and 3, a plurality of the plate plates 13 may be provided. A plurality of the plate plates 13a, 13b, 13c may be stacked in the vacuum space. The height at which the plurality of the cut-out plates 13a, 13b, 13c are stacked may be the same as the height of the vacuum space. That is, the plurality of cut-out plates 13a, 13b, and 13c may be stacked so as to fill the vacuum space, and the cut-out plates 13a and 13c disposed at the uppermost and lowermost ends, respectively, ). ≪ / RTI > The plurality of cut-out plates 13a, 13b, and 13c may be stacked in the same direction. In other words, the plurality of cut-out plates 13a, 13b, and 13c can be stacked in the direction in which the longitudinal directions of the crests of the cut-out core members 131 coincide with each other. The plurality of cut-out plates 13a, 13b, 13c can be stacked so that the crests and the mountains are in contact with each other between adjacent cut-out plates 13. [ In other words, the peaks of the upper one plate 13a and the peaks of the lower plate 13b located below can be laminated to each other. For this purpose, the cut-out plate 13b can be formed with the bone and the mountain being pushed in half the pitch compared with the cut-out plate 13a. According to this structure, when the layers are laminated to each other, the valleys of the one plate plate 13a and the peaks of the other plate plate 13b can come into contact with each other. As shown in Fig. 3, when the bones and the mountains are stacked so as to contact each other, the force concentrated on the valley of the one plate plate 13a is transmitted downward through the mountains of the plate plate 13b, So that the force can be efficiently dispersed. Therefore, according to such a laminated structure, it is possible to more firmly resist the deformation force of the panel plate 11. Although the three plate plates 13a, 13b and 13c are shown in FIGS. 1 to 3, the plate plates 13 may be provided in various numbers. For example, the plate plate 13 can be stacked with as many pieces as possible to fill up the vacuum space.

The cut-out plate 13 may be formed of an inorganic material including foamed concrete, expanded type rock, expanded clay, and glass fiber. Further, the plate plate 13 may be formed of various organic materials such as various kinds of PE, PP, PS, and the like. For example, the cutout plate 13 may be formed by twisting glass fibers. The cut-out plate 13 can be formed by bundling a pure glass fiber free of phenol resin used as an adhesive. In the case where a plurality of the plate plates 13 are provided, only one plate plate 13b may be formed of a bundle of pure glass fibers. Since the glass fiber has a low thermal conductivity, it can have an effect of lowering the thermal conductivity through contact between the cut-out plates 13.

4 is an exploded perspective view of a vacuum adiabatic panel according to an embodiment.

The vacuum insulated panel 2 according to one embodiment may include a panel plate 21, a sealing portion 22, and a cutout plate 23. In the description of FIG. 4, the contents overlapping with the above-described contents will be omitted.

A plurality of the plate plates 23 may be provided. A plurality of the plate plates 23a, 23b, 23c may be stacked in the vacuum space. The plurality of cut-out plates 23a, 23b, 23c can be stacked so that the longitudinal direction of the crests of the cut-out core members perpendicularly cross each other between the adjacent cut-out plates 23. For example, when the one plate plate 23a is arranged in the longitudinal direction, the other plate plate 23b may be arranged in the lateral direction, and the lower plate plate 23c may be stacked in the vertical direction again. According to this structure, the area of contact between the valleys of the one plate plate 23a and the mountains of the other plate plate 23b can be minimized. Therefore, while the force concentrated on the valley of the one plate plate 23a is sufficiently transmitted to the acid of the other plate plate 23b, the conduction phenomenon can be minimized as the contact area is minimized. That is, it is possible to increase the heat insulation efficiency of the vacuum insulation panel 2 while firmly supporting the deformation force of the panel plate 21. In FIG. 4, the three plate plates 23a, 23b and 23c are shown, but this is for convenience of description, and the plate plates 23 can be stacked in various numbers. In addition, the cut-out plate may be laminated by mixing the same directional lamination structure described in Figs. 1 to 3 and the vertical direction lamination structure described in Fig.

FIG. 5 is a side cross-sectional view showing an enlarged view of the outer surface of the panel plate according to one embodiment.

Referring to FIG. 5, a pair of panel plates 31 according to one embodiment may be formed so that the outer frame 311 is bent. The outer frame 311 may refer to the outer edge portion of the panel plate 31. The outer frame 311 can be bent, for example, smoothly, or bent. The pair of panel plates 31 can be arranged so that the curved outer peripheries 311 are oriented in directions symmetrical to each other. For example, the pair of panel plates 31 may be arranged in a direction in which the curved outer peripheries 311 face each other as shown in Fig. It should be noted that the degree of warpage, length and direction of the outer frame 311 shown in Fig. 5 are exemplary.

The sealing portion 32 can be interposed in the outer frame 311 of the pair of panel plates 31 in close contact with each other. The sealing portion 32 may be disposed along the outer frame 311 to seal the vacuum space so that a vacuum is formed inside the vacuum space. As the vacuum is formed in the vacuum space, the sealing portion 32 can be closely contacted to cover the inner and outer surfaces of the bent outer frame 311. Specifically, in the process of forming a vacuum in the vacuum space, a negative pressure sucking the sealing portion 32 may be formed in the vacuum space. A part of the sealing part 32 is sucked into the inner space of the curved outer frame 311 by the negative pressure so that the other part is pushed into the outer space of the curved outer frame 311 . Therefore, the sealing portion 32 is in close contact with the inner surface and the outer surface of the bent outer portion 311, and the inside of the vacuum space can be sealed. According to this structure, since the sealing portion 32 pushed into the outer space of the bent outer frame 311 pushes the outer frame 311, it is possible to convert the sucking force (negative pressure) into a pushing force (positive pressure). Therefore, the sealing portion 32 is tightly attached to the outer frame 311 through the positive pressure, so that the sealing portion 32 can be stably and strongly bound to the pair of panel plates 31, and the sealing force for sealing the vacuum space is improved .

The reinforcing supporter 44 can support and support the pair of panel plates 41 directly. The reinforcing supporter 44 can prevent the pair of panel plates 41 from being deformed. The reinforcing support body 44 can be installed in the vacuum space. The reinforcing support 44 may be installed through the cut-off plate 43. For this, a through-hole may be formed in the cut-out plate 43. For example, the through-hole may be formed in the cut-away core 431, or the cut-away core 431 may be omitted in some sections in the width direction of the crest, and the through-hole may be formed in the support plate 432.

The reinforcing support body 44 may be formed in various shapes. For example, the reinforcing support 44 may include a support post 441 and a column support 442, as shown in FIG.

The column base 442 can be connected to the inner surface of the panel plate 41. The column supports 442 may be provided as a pair. The pair of column supports 442 can be connected to the inner surfaces of the pair of panel plates 41, respectively. The column support 442 may be formed in a circular plate or ring shape.

A plurality of support pillars 441 may be provided. The plurality of support posts 441 can connect a pair of column supports 442. The plurality of support pillars 441 may be radially arranged along the circumferential direction with respect to the center of the column support 442. The support pillars 441 can be arranged to be inclined with respect to the pair of panel plates 41. [ The plurality of support pillars 441 may be radially arranged such that a truncated cone or a conical shape is formed. The distance from the center of each of the pair of column supports 442 to the point where the support pillars 441 are connected to the pair of column supports 442 may be different from each other. The reinforcing support 44 may be installed at one or more locations. When the reinforcing supporter 44 is provided at a plurality of positions, the reinforcing supporter 44 may be arranged so that the directions of the frustum or conical shape alternate with each other. According to this structure, the reinforcing supporter 44 can provide reinforcement for preventing the panel plate 41 from being deformed by the negative pressure in the vacuum space. On the other hand, the supporting columns 441 may be installed in a vertical direction with respect to the panel plate 41 so as to have a cylindrical shape, or may be provided in a single number. It should be noted that the shape, structure, number, size, and the like of the reinforcing supporter 44 shown in Fig. 6 are merely illustrative.
