1 to 4 show a wall structure using a panel according to an embodiment of the present invention.

As shown, the wall structure of the present invention includes a plurality of wall panels (11, 12, 13, 14), the plurality of wall panels (11, 12, 13, 14) mutually in the vertical direction and the lateral direction thereof Connected. Meanwhile, for convenience of description, in FIG. 1, the number 11 of FIG. 1 is the first panel 11, the number 12 is the second panel 12, the number 13 is the third panel 13, and the number 14 is the fourth panel 14. It is referred to as).

Each of the wall panels 11, 12, 13, and 14 includes first and second sheets 110 and 120, and the first and second sheets 110 and 120 are disposed to face each other, and the first sheet ( 110 is adjacent to the outer space of the building, the second sheet 120 is adjacent to the interior space of the building. Between the first and second sheets 110 and 120 may be interposed a heat insulating material 130 made of a fibrous or powder material, such as mineral fiber or polymer resin.

On the other hand, the heat insulating material 130 of the present embodiment is built with a heat insulating material 130 composed of mineral fibers such as mineral wool (mineral wool). Here, the mineral wool is a high heat-resistant mineral fiber manufactured artificially of rock, and has characteristics of non-combustibility, light weight, heat insulation, sound absorption, and durability.

Meanwhile, as shown in the enlarged view of FIG. 2, each of the first and second sheets 110 and 120 is composed of a double composite plate of the outer plates 111 and 121 and the inner plates 112 and 122. The outer plate 111 of the first sheet 110 is adjacent to the exterior space of the building, and the outer plate 121 of the second sheet 120 is adjacent to the interior space of the building.

As the double structure of the outer plates 111 and 121 and the inner plates 112 and 122 is used, the stiffness of each sheet 110 and 120 itself is not increased but the expensive materials are used less. It can increase.

The outer plates 111 and 121 are exposed to the outside, and the material may be relatively expensive materials such as stainless steel, aluminum, copper, etc., which are excellent in workability (surface treatment and surface finish), corrosion resistance, and appearance. have.

The inner plates 112 and 122 should be made of a material that is excellent in workability and has sufficient strength to sufficiently support the outer plates 111 and 121 as parts not exposed to the outside to secure overall molding processability. However, since the inner plates 111 and 121 are not exposed to the outside, relatively inexpensive materials such as galvanized steel sheet, stainless steel, aluminum, color steel sheet, cold rolled steel sheet and pickling steel sheet may be used.

The adhesive layers 113 and 123 are interposed between the outer plates 111 and 121 and the inner plates 112 and 122, and the outer plates 111 and 121 and the inner plates 112 and 122 are interposed therebetween. ) Are integrated by tightly coupling to each other.

The adhesive layers 113 and 123 may be made of an adhesive resin material containing ethyl acetate, acryl copolymer, isopropyl alcohol, toluene, vinyl acetate, acetaldehyde, etc., and the adhesive layers 113 and 123 may be formed of an outer plate ( 111, 121 and the inner plate 112, 122 has a viscosity of at least 2000 ~ 5000cps to maintain a constant adhesion.

Meanwhile, the adhesive layers 113 and 123 are made of an adhesive resin material having a viscosity of about 2000 to 5000 cps, and are formed to have a thickness of about 0.01 to 0.1 mm, and thus the outer plates 111 and 121 and the inner plates 112 and 122. ) As well as the adhesion of each sheet 110, 120 can contribute to improving the vibration damping, sound-absorbing, heat insulating properties.

In addition, the outer plates 111 and 121 are relatively thinner than the inner plates 112 and 122, and thus, material costs can be reduced by reducing the usage of the outer plates 111 and 121, which are relatively expensive materials. There are advantages to it. For example, the thicknesses of the outer plates 111 and 121 may be about 0.1 to 0.4 mm, and the thickness of the inner plates 112 and 122 may be about 0.4 to 1.2 mm.

As described above, each sheet 110 and 120 of the present invention adopts a double composite plate structure in which the outer plates 111 and 121 and the inner plates 112 and 122 are firmly bonded by the adhesive layers 113 and 123. The overall support stiffness can be significantly increased without increasing the thickness of each sheet 110, 120, and the workability and appearance can be improved.

Protrusions 150 and grooves 160 are formed at the upper and lower ends of each of the wall panels 11, 12, 13, and 14, and the wall panels adjacent to each other in the vertical direction are formed of the first panel 11 and the first panel. The second panel 12 positioned on the upper portion of the panel 11 is coupled to each other, and the third panel 13 and the fourth panel 14 positioned on the upper portion of the third panel 13 are coupled to each other. For example, the protrusion 150 of the first panel 11 is fitted into the groove 160 of the second panel 12 so that the first and second panels 11 and 12 are coupled in the vertical direction, and the third panel As the protrusion 150 of 13 is fitted into the groove 160 of the fourth panel 14, the third and fourth panels 13 and 14 may be coupled in the vertical direction.

In order to facilitate standardization of the panel in the manufacturing process, the first and second sheets 110 and 120 are bent apart from each other to form a gap 136 as shown in FIG. 2. Therefore, a part of the thermal insulation material 130 of the fiber material leaks to the outside through the gap 136 and causes an environmental problem, and also the wall panels 11 and 12 due to the penetration of external foreign matter or moisture through the gap 136. , 13, 14) may also lower the thermal insulation performance and rigidity.

In addition, the reinforcing insulation member 140 may firmly reinforce the coupling force of the protrusions 150 and the grooves 160 of the wall panels 11, 12, 13, and 14. As the reinforcing insulation material 140, a foamable resin such as an olefin flame retardant foam having excellent strength may be preferable.

In addition, the present invention by interposing the sealing member 176 such as sealant, silicone rubber, synthetic resin, natural rubber between the protrusions 150 and the grooves 160 of the adjacent wall panels 11 and 12, 13 and 14 in the vertical direction It can also reliably block the ingress of moisture or foreign objects.

As shown in FIGS. 1 and 4, the wall panels 11, 12, 13, and 14 are adjacent to each other in the lateral direction, and the wall panels 11, 12, 13, and 14 are fastened to the frame 18 of the building. The sealing connection member 200 is sealingly installed between the wall panels 11 and 12, 13 and 14, which are connected to each other by being coupled to each other and are connected in the lateral direction. The side joins are sealed off.

The outer side of the side finishing material 170 is formed with a coupling groove 171 to which the sealing connection member 200 is coupled, and a stepped portion 173 is formed at one side of the coupling groove 171. Since the coupling groove 171 is formed to be inclined at a predetermined angle, the side surface of the sealing connection member 200 may be more tightly coupled to the coupling groove 171.

The sealing connecting member 200 has a center rib 201 formed in the center and a plurality of sealing ribs 202 formed on both left and right sides of the center rib 201. The central rib 201 has a pair of hollow portions 201a symmetrically formed therein, and each sealing rib 202 is formed to be inclined at a predetermined angle. In addition, the plurality of sealing ribs 201 are spaced apart from each other at regular intervals, and their lengths are set differently. Thus, the sealing ribs 202 of the sealing connection member 200 may be hermetically coupled in the coupling groove 171 of the side finish material 170.

In addition, the sealing connecting member 200 has a pair of fitting ribs 203 spaced apart from the sealing ribs 202, the fitting rib 203 is fitted to the stepped portion 173 of the coupling groove 171. As a result, both sides of the sealing connection member 200 may be firmly coupled to adjacent wall panels 11 and 13, 12, and 14.

The front end of the sealing connection member 200 is adjacent to the frame 17 of the building, and a sealing material 18 such as a sealant may be interposed between the front end of the sealing connection member 200 and the frame 17 of the building. The sealing property of the sealing connecting member 200 may be further reinforced by the sealing material 18.

5 to 8 show the wall structure of the building according to another embodiment of the present invention.

As shown, the heat insulating material 130 according to another embodiment of the present invention may be composed of a polymer resin such as poly isocyanurate resin, polyurethane resin (poly uretan resin) and the like. Thus, since the first sheet 110 or the second sheet 120 may not be provided with sufficient support rigidity by the heat insulating material 130, the reinforcing plate inside the first sheet 110 or the second sheet 120. 180 is installed. The reinforcing plate 180 may be installed inside any one of the first sheet 110 and the second sheet 120, and both the first sheet 110 and the second sheet 120 may be installed inside. May be 5 to 8 illustrate and explain a state in which the reinforcing plate 180 is installed on the first sheet 110 side for convenience of description, the present invention is not limited thereto.

The reinforcing plate 180 has a base portion 181 and a plurality of support protrusions 182 protruding from the base portion 181, and the plurality of support protrusions 182 is an inner surface of the first sheet 110, in particular, It is configured to contact the inner plate 112 of the first sheet (110).

The plurality of support protrusions 182 have a hollow portion 182a therein, and air is introduced into the hollow portion 182a to form an air layer. Each support protrusion 182 has a contact surface 182b on one side thereof, and as the contact surface 182b contacts the inner plate 112 of the first sheet 110, the first sheet 110 has a structural rigidity. Can be increased. Thus, the wall panels 11, 12, 13, 14 of the present invention can significantly improve the thermal insulation performance by having an air layer therein. On the other hand, the support protrusion 182 is composed of a rectangular cross-sectional structure in Figures 5 to 8, but may be of a semi-circular or arc-shaped curved cross-sectional structure.

In addition, since a separate filling is not interposed in the space 189 between the base portion 181 and the first sheet 110 of the reinforcing plate 180, the space 189 may be a separate air layer.

As such, in the present invention, the support protrusions 182 of the reinforcing plate 180 support the inner surface of the first sheet 110 so that the rigidity of the wall panels 11, 12, 13, and 14 itself may be reinforced. In addition, as the air flows through the air layers 182a and 189, the smoothness of the first sheet 110 is uniformly maintained by freely responding to thermal expansion and thermal contraction of the first sheet 110 according to an external temperature condition (temperature rise or fall). There is an advantage to keep it.

In addition, due to the structure in which the separate air layers 182a and 189 are formed between the first and second sheets 110 and 120, the heat insulating property may be improved.

Alternatively, as shown in FIG. 9, the sound absorbing material 190 is filled in the space between the base portion 181 of the reinforcing plate 180 and the first sheet 110, and the first sheet 110 has a plurality of sound absorbing holes ( 117 may be formed.
