BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated honeycomb structure and a method of assembling the same, and more particularly, to a prefabricated honeycomb structure having improved half-honeycomb structure that can be assembled in the field, And a method of assembling the same.

Panels made of metal are widely used as building exterior materials. Such metal panels include aluminum composite panels, aluminum bonding panels, and stainless steel bonding panels. These conventional metal composite panels or bonded panels have advantages and disadvantages.

First, an aluminum composite panel is formed by laminating a polyethylene (PE) resin having a thickness of approximately 5 mm to 6 mm between aluminum sheets having a thickness of approximately 0.5 mm to 0.6 mm, and is excellent in workability and economy and is excellent in smoothness.

However, aluminum composite panels are very dangerous because they can be transferred to the room by melting aluminum or PE resin in case of fire, and when exposed to rain or sea breeze, surface damage may occur along the surface cracks. This problem is particularly severe in the bending plane.

Next, the aluminum junction panel and the stainless steel junction panel are formed by joining a plated steel sheet having a thickness of approximately 0.5 mm to 2.0 mm to aluminum having a thickness of approximately 0.3 mm to 0.5 mm or stainless steel having a thickness of approximately 0.1 mm to 0.3 mm will be. Here, the coated steel sheet forms a structure (body), and aluminum or stainless steel forms a surface layer. The coated steel sheet may be a ternary coated steel sheet containing Zn, Al, and Mg elements, and in this case, the corrosion resistance is excellent. In addition, aluminum can be coated with fluorine on the aluminum junction panel, and a Ti coating layer can be formed by physical vapor deposition, or a surface treatment such as a nanoceramic coating can be performed.

Such a metal bonded panel generally uses a thin plate (thickness of approximately 0.8 mm to 1.5 mm) rather than a thick plate, which is heavy in the case of heavy plates, difficult to surface, and economically disadvantageous.

However, in the case of a metal bonded panel using a thin plate, when the panel is enlarged, the flatness becomes poor. As a result, the outer wall of the building may be worn out during actual construction or may be visually bad when reflected.

Therefore, in the case of a metal panel using a thin plate, a technique of arranging the honeycomb structure between the panels has been developed in order to increase the smoothness.

Such a honeycomb structure is preferably made of the same kind of metal as the panel. For example, it is preferable to use an aluminum honeycomb structure for an aluminum panel in terms of bonding performance. If an aluminum honeycomb structure is bonded to a stainless steel panel, a peeling phenomenon may occur due to an oxide film (passivation film) of stainless steel.

As described above, aluminum composite panels have disadvantages such as human hazards and surface damage at the time of fire, and therefore, aluminum bonded panels or stainless steel bonded panels are advantageous. However, since a galvanized steel sheet is used for such a joining panel, the honeycomb structure for enhancing the strength and smoothness of the joining panel can be made of a plated steel sheet of the same material as the panel, but conventionally, such a honeycomb structure has never been developed.

Meanwhile, a conventional honeycomb structure is manufactured in a factory, transported to a construction site, processed and installed, or transported to a manufacturing site of a metal panel to bond a honeycomb structure and a metal panel to produce a final product. However, it is not only difficult to produce the honeycomb structure due to the shape characteristics thereof, but also has a problem in that the transportation cost is increased because the volume of the honeycomb structure is larger than that of the honeycomb structure.

In addition, when spot welding is performed to join a metal honeycomb structure to a metal panel, there is a problem that the workability is deteriorated due to process time and cost.

1 is a schematic perspective view of a building exterior panel including a honeycomb structure.

The metal lower plate panel 20 and the upper plate panel 30 may be coupled to the upper and lower sides of the honeycomb structure 10, respectively. The shape and the assembling method of the honeycomb structure 10 will be described later.

The metallic lower panel 20 may be composed of a lower face 21, side faces 22 provided at both side ends of the lower face 21 and flange faces 23 provided on the side faces 22, respectively. Such a structure is easy to accommodate the honeycomb structural body 10 therein and to be coupled to a steel structure or a tube structure constituting the skeleton of the building.

By accommodating the honeycomb structured body 10 between the metallic lower panel 20 and the upper panel 30, sufficient strength and smoothness can be maintained even if the panel is enlarged.

Hereinafter, the assembled type honeycomb structure will be described in detail with reference to the drawings. FIG. 2 is a perspective view of a prefabricated honeycomb structure according to an embodiment of the present invention, FIG. 3 is a view for explaining a joining method of the prefabricated honeycomb structure according to FIG. 2, and FIG. 4 is a view showing a combination of the prefabricated honeycomb structure according to FIG. 5 is a view for explaining a method of loading the assembled type honeycomb structure according to FIG. 2. FIG.

As shown in FIG. 2, the assembled honeycomb structure 10 according to the present invention has a protruded-concave shape repeated to have a half-honeycomb shape. Here, the " half honeycomb " shape is a half of the honeycomb structure, meaning that one honeycomb structure is formed by joining two honeycomb structures 10 together. That is, when one protruding portion of the honeycomb structure and one concave portion of the other honeycomb structure are bonded, a single honeycomb structure is formed.

2, a portion located on the lower side of the assembled type honeycomb structure 10 will be referred to as a first surface 100, and a portion located on the upper side will be referred to as a second surface 110. Referring to FIG. The first surface 100 and the second surface 110 are provided with engaging members, respectively, and the engaging members are formed in shapes corresponding to each other so as to be able to engage with each other.

Referring to FIG. 2, a first groove 102 and a second groove 103 are formed on the first surface 100, and between the first groove 102 and the second groove 103, a plate portion 101 may be provided. The first groove 102 and the second groove 103 may have the same shape as each other, and each of the first groove 102 and the second groove 103 has an elongated groove shape whose upper side is opened.

In addition, the groove 111 may be formed on the lower side of the second surface 110 in such a manner that the plate portion 101 can be engaged with the plate portion 101. Here, " upper side " or " lower side " should be understood as directions relative to each other depending on the position of the assembled type honeycomb structure 10.

In this embodiment, the plate portion 101 and the groove portion 111 are a first engaging member and a second engaging member, respectively. Referring to FIG. 3, the plate portion 101 and the groove portion 111 are different from the groove portion 111a of any one of the assembled type honeycomb structures 10a The plate portions 101b of the prefabricated honeycomb structure 10b of the prefabricated honeycomb structure 10b are staggered to each other so that the two prefabricated honeycomb structures 10a and 10b can be joined to each other. This method is repeated to make a honeycomb structure as shown in Fig.

Referring to FIG. 2, the first surface 100 and the second surface 110 are connected to each other through the inclined surfaces 120 and 130 to form a repeated structure. That is, referring to FIGS. 2 and 3, the first surface, the second surface, and the inclined surfaces of the two assembled honeycomb structures 10a and 10b form one hexagonal hollow structure.

By combining the plate portion 101 and the groove portion 111, the two prefabricated honeycomb structures can be joined together. However, the two prefabricated honeycomb structures are not completely fixed by this combination, and only the semi-fixed connection is achieved.

4, the prefabricated prefabricated honeycomb structures 10a and 10b can be fixed to the metal lower plate panel 20, for example, via an adhesive 40, whereby the prefabricated honeycomb structures 10a and 10b can be fixed to the metal lower plate panel 20, And the lower plate panel 20 can be completely fixed in position. The adhesive 40 may be an epoxy or an urethane adhesive. In the case of such an adhesive, a protruding shape 41 is formed at a bonding site through a curing process, thereby making it possible to provide a more stable and stable fixing bond.

Since the prefabricated honeycomb structure 10 having a half-honeycomb structure can bend and cut one metal plate, the manufacturing process is simplified, and cost and time are saved. 5, the manufactured prefabricated honeycomb structural body 10 can be packaged, stored, and transported in a stacked state, so that compared with the conventional honeycomb structural body, Storage cost and the like can be greatly reduced.

Further, since the assembled honeycomb structure 10 can be assembled at appropriate lengths and numbers in a building construction site or a panel manufacturing site as required, it is excellent in workability. Further, since the assembled honeycomb structural body 10 can be used successively in the longitudinal direction thereof, it can be easily applied to panels of various lengths.

Further, as described above, since the plurality of prefabricated honeycomb structures 10 can be easily coupled by engaging the plate portion and the groove portion, it is easier to manufacture than the case of using, for example, welding, and the transportation / .

Meanwhile, the prefabricated honeycomb structure 10 may be formed of a plated steel plate. The strength against the specific gravity of the coated steel sheet is excellent, and the bonding performance with the metal panel made of the same material is excellent. As described above, a plated steel sheet is used for the aluminum bonding panel and the stainless steel bonding panel. In order to improve bonding performance and efficiency by using the same metal as the metal bonding panel, the honeycomb structure 10 is preferably formed of a plated steel sheet . On the other hand, when the honeycomb structure 10 is made of aluminum, the bonding performance with the plated steel sheet is poor, and when the honeycomb structure 10 is made of stainless steel, an oxide film is generated.

Here, the thickness of the coated steel sheet may be 0.1 mm to 2.0 mm. When the thickness of the plated steel sheet is 0.1 mm or less, it is difficult to maintain adequate strength and difficulty in the construction. When the thickness of the plated steel sheet is 2.0 mm or more, the workability is poor and the economical efficiency is poor.

Although the joining member by the plate portion and the groove portion has been described so far, other combinations of joining members are also possible. 6 to 9 are perspective views of a prefabricated honeycomb structure according to another embodiment of the present invention.

6, a protruding rib 104 is formed at the center of the first surface 100 of the assembled type honeycomb structure 10 and a protruded rib 104 is formed at the center of the second surface 110, (114) may be formed. In this embodiment, the projecting ribs 104 and the receiving grooves 114 become the first engaging member and the second engaging member, respectively.

The protruding ribs 104 may be provided as circular protrusions protruding outwardly from the first surface 100 through pressing or drawing processing. Alternatively, as shown in FIG. 7, a rectangular protruding rib 105 is also possible, and other various protrusions are possible.

The receiving groove 114 may be provided as a circular hollow through the piercing process on the second surface 110. Alternatively, as shown in FIG. 7, a rectangular hollow receiving groove 115 may be used, and various other hollows may be used.

The projecting ribs 104 (105) and the receiving grooves 114 (115) can be coupled with each other to maintain a semi-fixed state.

8, the first plate portion 101 provided on the first surface 100 and the second plate portion 116 provided on the second surface 110 may be replaced by a first coupling portion Member and the second engagement member.

That is, a first groove 102 and a second groove 103 are provided on the first surface 100, and a first plate portion 101 (see FIG. 1) is provided between the first groove 102 and the second groove 103, May be provided.

The third groove 117 and the fourth groove 118 The second plate portion 116 may be provided between the first plate portion 116 and the second plate portion 116. [ The first plate portion 101 and the second plate portion 116 can be engaged with each other so that the first to fourth grooves 102 to 103 (Not shown).

Referring to FIG. 9, the elastic protrusion and the receiving groove can be fixed by elastic coupling. As shown in the figure, the protruding elastic portions 107 and 108 provided at the center of the first surface 100 and the receiving recess 119 formed at the center of the second surface 110 are connected to the first engaging member and the second engaging member, As shown in Fig. Here, the receiving groove 119 is provided so as to be able to engage with the protruding elastic portions 107,

The protruding elastic portions 107 and 108 may be made of a pair of protruding members, and the protruding members may have a shape protruding outward in a step or a zigzag shape (see Fig. 9 (a)). An opening 106 may be provided between the pair of protruding elastic portions 107 and 108. The protruding elastic portions 107 and 108 can be formed by providing a cutting line having an " H " shape at the center of the first surface 100 and bending the cut line with the cutting line.

FIG. 9 (b) is a partial cross-sectional view showing a state in which a protruding elastic portion and a receiving groove provided in two assembled type honeycomb structures are combined. The protruding elastic portions 107a and 108a of the first honeycomb structure 10a can be inserted and fixed in the receiving groove 119b of the second honeycomb structure 10b.
