The present invention relates to a composite composite panel for construction, and more particularly, to a multifunctional composite panel which can be utilized for heating by acquiring solar heat and improving heat insulation performance and sound absorption performance.

As a material constituting the outer wall, roof, and other wall of the building, a prefabricated composite panel with excellent thermal insulation performance and easy construction is widely used. Such a composite panel should have excellent thermal insulation performance as well as durability against the external environment, for example, waterproofing, oxidation resistance, corrosion resistance, etc., structural strength should be maintained, and there should be no deformation on external force. In addition, the composite panels used for the exterior walls and roofs of buildings should have excellent sound absorption properties to block or reduce noise.

1 schematically illustrates an example in which a plurality of single panels are combined to be used as a building exterior wall 10. One or more panels 12 are interconnected between columns or vertical structures constituting the skeleton of the building to be used as a wall blocking the interior and exterior of the building.

Such a panel has a composite structure in which an internal insulation is inserted between two sheets or plates, and a porous foam insulation having excellent insulation performance is mainly used as the insulation. Such foam insulation has been applied to many insulation products because it is light and easy to manufacture as well as cost-effective.

The structure of a conventional composite panel using a porous foam insulation is shown in Figure 2a. According to FIG. 2A, a heat insulating material 23 is inserted between the first sheet 21 and the second sheet 22. When urethane foam is used as the heat insulator 23, the air layer 24 is formed by bubbles in the heat insulator during the foaming process.

Although the air layer 24 may have a fixed position inside the heat insulator 23, most of the air layer 24 moves to the upper portion in the curing process of the foam. Accordingly, as shown in FIG. 2B, the air layer 24 ′ moves near the first sheet 21. If the first sheet is a surface facing the inside of the building, the effect may be small, but if the surface facing the outside of the building, the air layer 24 'is expanded by heat transmitted from the outside.

FIG. 2C schematically shows the expansion of the air layer 24 ″ located near the inner surface of the first sheet 21 by heat. As a result of the expansion of the air layer 24 ″, the first sheet 21 ′ corresponding to the outer surface of the panel is deformed as shown. Such deformation not only impairs the aesthetics of the panel itself, but also the strength of the panel, and if the deformation part corresponds to the joint between panels, the connection state of the panel is deteriorated, resulting in a fatal effect on the function as the exterior wall of the building. .

Therefore, in the case of using a composite panel having a foam insulation as a material for building exterior walls, there is a strong need to improve the durability by preventing deformation of the panel by expansion of the air layer inside the panel.

On the other hand, the conventional composite panel focuses only on the insulation performance, so the sound absorption characteristics were not good. If a separate sound absorbing panel is considered to improve sound absorbing properties, additional problems such as an increase in construction cost may occur. Therefore, there is an urgent need for a multifunctional composite panel that has excellent thermal insulation and sound absorption characteristics and combines manufacturing economics. On the other hand, there is a need for a multifunctional composite panel including a function that can be actively utilized to maintain the temperature (heating) inside the building by effectively utilizing the external heat applied to the panel, in particular solar heat.

Accordingly, it is an object of the present invention to provide a new building composite panel which improves durability by preventing deformation of the sheet on the surface due to thermal expansion of the inner air layer.

Another object of the present invention is to provide a composite panel which improves the strength of the panel itself and doubles the insulation performance.

It is yet another object of the present invention to improve sound absorption properties in building composite panels.

In addition, another object of the present invention is to provide a multifunctional composite panel that can be used to maintain the temperature (heating) inside the building by actively utilizing the heat applied to the composite panel.

Other objects and features of the present invention will become apparent from the following detailed description.

Coloring can add aesthetic appearance. In addition, in the panel, the surface exposed to the exterior of the building is preferably larger in thickness of the sheet constituting the surface than the surface facing the interior of the building.

In addition, according to the second aspect of the present invention, the first sheet, the second sheet for maintaining a space at a predetermined distance from the first sheet, the heat insulating material is filled in the space between the first sheet and the second sheet and And an air trap member positioned between the heat insulator and the first sheet, and a sound absorbing member positioned between the air trap member and the first sheet. Preferably, the air trapping member is formed to protrude in one direction on the surface of the hard plate and has a plurality of empty spaces formed therein, and the sound absorbing member preferably has a panel shape in which a plurality of through holes corresponding to the spaces are formed. .

The composite panel according to the second aspect of the present invention may provide a multifunctional building composite panel having insulation and sound absorption properties as well as preventing deformation by the air layer inside the composite panel and improving sound absorption characteristics.

Preferably, the sound absorbing member is molded into a predetermined shape and used in a panel manufacturing process in a state of being assembled to the air trapping member. The first sheet corresponds to the inner surface or the outer surface of the building according to the use of the composite panel, and also to absorb sound energy by forming a plurality of holes on the surface of the first sheet to improve sound absorption characteristics. It may be easily absorbed by the member.

According to a third aspect of the present invention, there is provided a porous sheet which is filled in a space between a first sheet, a second sheet holding a space at a predetermined distance from the first sheet, and a space between the first sheet and the second sheet. It includes a foam insulation, and an air trap member positioned between the foam insulation and the first sheet, the air trap member is formed to protrude in one direction on the surface of the hard plate, a plurality of spaces are formed inside the hollow plate, Provided is a building composite panel comprising at least two communication holes for flowing the heated air of the space existing between the first sheet and the air trapping member to the outside.

In the communication hole, when a plurality of composite panels are connected to each other to form a panel system, each communication hole is preferably connected to each other by an air flow pipe.

The composite panel may include at least one air circulation fan, and in the case of a panel system, a plurality of composite panels may be connected to each other to connect one air circulation fan to one side of an air flow pipe.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

3 is a perspective view showing a composite panel according to a first embodiment of the present invention. As shown, the composite panel includes a porous foam insulation 33 in the interior space between the first sheet 31 and the second sheet 32, the first sheet 31 and the insulation material 33 The air trapping member 35 is inserted in between.

The position of the air trapping member 35 is preferably located between the sheet and the heat insulator which is exposed from the panel to the outside of the building.

The air trapping member 35 is preferably a structure in which a plurality of spaces are formed in the plate on the sheet. 4 shows an air trapping member 35 according to an embodiment of the present invention.

Referring to FIG. 4, it can be seen that a plurality of protrusions 35b are formed in a predetermined arrangement on the surface of the plate material 35a of a predetermined size. The protrusions 35b are all formed in a predetermined direction with respect to the plate 35a, and the mutual spacing between the protrusions is preferably constant. In addition, it is preferable that the height of each protrusion 35b is constant.

As the air trapping member 35, it is preferable to use a hard plastic product or a metal product having excellent strength or hardness. PVC-based materials are preferred as the plastic product, and aluminum may be used as the metal, but is not limited thereto. It would be advantageous in the manufacturing process to form an air trapping member by molding into a predetermined shape using such a material in advance, and to apply the molded product as an insert member in the panel assembly step according to the present invention.

The air trapping member 35 does not necessarily have to be thick because its strength against load is high due to a structural feature in which a plurality of protrusions are formed. Figure 5a shows a cross section of the air trapping member of Figure 4, the thickness of the air trapping member is determined in consideration of the overall size or thickness of the panel, the preferred thickness (t) range is 0.5 to 3 mm, more preferably 1 to 2 mm.

On the other hand, the overall strength of the air trapping member is determined according to the height of the space portion of the air trapping member or the space between the space portion, and also affects the air trapping performance should be designed most optimally according to the shape of the panel. The height h of the space portion is preferably about 5 to 20 mm, and the spacing w between each space portion is preferably 5 to 15 mm.

5b and 5c show other embodiments of the air trapping member. As shown, it can be seen that the shape of the space portion is semicircular in the case of FIG. 5B and elliptical in the case of FIG. 5C. However, the present invention is not limited to this embodiment, and the shape of the space part may be variously modified according to the use or structural form of the panel.

Looking briefly at the manufacturing process of the composite panel according to the present invention. First, the metal sheet used for the first sheet and the second sheet is cut in a predetermined form to finish the rim. Then, the side block or the side paper is attached to the panel side portion while assembling into one panel so that the first sheet and the second sheet maintain a predetermined thickness. At this time, the air trapping member previously formed into a predetermined shape is attached to the inner surface of the first sheet using an adhesive. (An adhesive may be applied to the first sheet or the air trapping member, for example, after the adhesive is applied to the air trapping member, the first sheet and the air trapping member may be bonded to each other.) Next, a foamable heat insulating material inside the panel. Filling the foam and foaming the insulation in the state maintained to prevent deformation of the panel by a press. After the foaming process, the composite panel is completed by curing for a predetermined time.

The cross section of the completed composite panel is typically shown in FIG. The air layer 34 'formed during the foaming of the insulation inside the panel moves to the space 36 in the protrusion of the air trapping member 35 and is trapped during curing. In addition, the air layer 34 present inside the heat insulator 33 also subsequently moves to another space 36 'over time and is eventually captured.

The air layer trapped in the space part is kept intact without further thermal expansion in the space part and does not cause deformation due to swelling in the first sheet. Thus, the shape of the panel can always maintain its original appearance.

In addition, the panel has the advantage that the overall strength increases due to the rigidity of the air trap member. That is, each protrusion of the air trapping member plays an auxiliary role of preventing deformation of the sheet or deformation of the internal insulation from external force applied to the panel as if the tunnel withstands the upper load.

In addition, the composite panel according to the present invention doubles the overall heat insulating performance of the panel because the space between the space portion of the air trapping member acts as an additional heat insulating space, resulting in a double heat insulating effect with the heat insulating material.

7 is a cross-sectional view showing a composite panel according to a second embodiment of the present invention. As shown, it can be seen that the sound absorbing member 40 is inserted into the space between the first sheet 31 and the air trapping member 35.

The sound absorbing member 40 may use a sound absorbing material that is commonly used. For example, a glass fiber-based or polyester-based sound absorbing material may be used, and other well-known sound absorbing materials may be used.

The first sheet corresponds to an inner surface or an outer surface of a building depending on the use of the composite panel. That is, when the sound absorption characteristics are required for the noise generated from the inside of the building, the first sheet corresponds to the inner wall of the building, but in some cases, it is necessary to prevent the noise outside the building from being transmitted to the inside. One sheet may be used as the surface of the building's exterior walls. A plurality of holes 31 ′ may be formed in the first sheet as shown in FIG. 8A to more easily absorb the propagated sound energy.

Since the sound absorbing member 40 is located in the space between the first sheet 31 and the air trapping member 35, a structure having a hole therein is preferable. For example, as shown in FIG. 8B, a structure in which a plurality of through holes 40 'are formed in one predetermined type of panel is preferable. In such a structure, the through hole 40 'is formed to correspond to the protruding space portion 35b of the air trapping member 35, so that the space portions 35b of the air trapping member 35 are inserted into the through hole 40'. Since the sound absorbing member 40 and the air trapping member 35 can be sandwiched with each other, the stacked structure can be formed. FIG. 8C shows an example of a structure in which the sound absorbing member 40 and the air trapping member 35 are laminated with each other while the through hole 40 'and the space 35b are fitted.

Looking at the example of the manufacturing process of the composite panel according to the second embodiment of the present invention, first, the metal sheet used for the first sheet and the second sheet is cut in a predetermined shape to finish the rim, and molded in a predetermined shape in advance In the state where the air trapping member and the sound absorbing member are laminated, the laminate is attached to the inner surface of the first sheet by using an adhesive, the foam insulation is filled in the panel, and the panel is pressed and held to prevent deformation of the panel. The composite panel can be completed by foaming the insulation. Such a manufacturing process can be performed in one continuous process to improve productivity and economics.

In the composite panel according to the second embodiment of the present invention, the sound absorbing member inserted into the space portion between the air trapping member and the first sheet acts as an additional heat insulating layer, so that a double heat insulating effect can be expected together with the heat insulating material. will be. Therefore, according to the present invention, a multifunctional composite panel capable of increasing the overall durability of the panel together with the doubled sound absorption and heat insulation performance is possible.

9A and 9B show a composite panel according to a third embodiment of the present invention. First, referring to FIG. 9A, the heat (mainly solar heat) applied from the outside of the panel typically shows an increase in the air temperature inside the panel. For example, if the first sheet 31 faces away from the building, it is exposed to the sun's rays. Since the first sheet is generally a metallic material, it is easily heated by solar heat, and thus, if there is an air layer inside the panel, the temperature of the air layer is quickly increased.

In the composite panel according to the present invention, there is a space 37 connected to each other between the first sheet 31 and the air trapping member 35. Referring to the air trapping member 35 of FIG. 4, it will be clearly understood that these spaces 37 are spaces of connected network structures without being disconnected from each other.

The space 37 is heated by external heat transmitted through the first sheet 31 to raise the temperature, and if the composite panel is used vertically on the building exterior wall, the raised air in the space 37 is naturally Convection circulation is possible.

FIG. 9B illustrates a cross-sectional structure of a composite panel according to a third embodiment of the present invention. Unlike the previous embodiment, FIG. 9B penetrates through the second sheet 32 and the heat insulating material 33 inside the panel, and the space portion ( It can be seen that the communication holes 51 and 52 leading to 37 are formed. These communication holes 51 and 52 serve as passages through which air existing in the space 37 moves to the outside of the panel. The communication hole 51 and the communication hole 52 will have an air inlet and an air outlet, or vice versa, depending on the installation position or method of the panel, respectively.

If the panel is installed vertically in the building, the air whose temperature is raised in the space 37 may be circulated to the outside through the communication holes 51 and 52 without a separate external device by natural convection. However, if more active circulation is required for the air inside the panel, or if the panel is installed horizontally or close to the horizontal, such as the roof of the building may be separately connected to the air circulation fan to the panel.

When the composite panel according to the present invention is actually used in a building, a plurality of panels are connected to each other to form a complex single panel system. In such a case, a more systematic configuration is required to use the building with heat applied to the panel. 10 schematically shows the configuration of such a composite panel system.

For example, for convenience of description, a composite panel system in which three composite panels 30a, 30b, and 30c are connected to each other will be described. Each composite panel 30a, 30b, 30c has communication holes 51, 52 on one side of the panel, respectively. The two communication holes in one panel are preferably formed in different positions from each other, and it is suitable for the system configuration to allow the communication holes of each panel to be formed in a similar position to each other.

As shown in FIG. 10, one communication hole 51 is formed at the bottom of the panel, and serves as a passage for inflow of air, and another communication hole 52 is formed at the top of the panel, for air discharge. It acts as a pathway.

It can be seen that the passage for the air inlet is connected to each of the one air flow pipe 54, the air flow pipe 54 is the air circulation fan 55 for forcing air circulation on one side (one end to the end) ) This system configuration is very advantageous in that air flow can be forced simultaneously to each panel 30a, 30b, 30c through one fan.

Unlike the example of FIG. 10, which is simplified for convenience of description, it would be suitable for a panel system that is actually constructed to have a mesh structure so that the air flow pipe can be connected to not only parallel panels but also vertically positioned panels.

In addition, various design changes and structural improvements of the present invention will be apparent to those skilled in the art within the scope of the technical spirit set forth in the appended claims, and therefore such design changes and structural improvements will be included in the technical spirit of the present invention.

As described above, according to the present invention, the thermal insulation performance and sound absorption performance of the composite panel for building can be greatly improved, and durability of mechanical strength and the like can be secured to ensure product reliability. In particular, the deformation caused to the panel surface by the air layer included in the heat insulating material inside the panel can be prevented at the source. In addition, by increasing the strength of the composite panel itself to increase the durability, thereby making the structure used in the panel can be more structurally robust. On the other hand, the composite panel according to the present invention has the advantage that the manufacturing process is relatively easy to significantly improve the productivity. In addition, the composite panel of the present invention provides an advantage of energy utilization by presenting an improved structure that can be used to heat the air of the inside of the panel to increase the temperature inside the panel due to external solar heat in a single panel. Such solar-acquisition composite panels will significantly reduce the construction cost compared to building the building's exterior wall itself to be solar-capable. The composite panel according to the present invention can be effectively used not only for new building construction but also for remodeling of existing buildings, and can be used for various construction fields such as large buildings and simple buildings.
