Description

Construction exterior material, sandwich panel and its manufacturing method {CONSTRUCTION MATERIALS AND MANUFACTURING METHOD THEREOF}

The present invention relates to a building exterior material, specifically, to a building exterior material having a gap removed, a sandwich panel and a method for manufacturing the same.

In general, the building exterior material has been used by attaching a building exterior material arbitrarily sized to the exterior wall of the building for the effect of protecting and decorating the exterior wall when building the building.

Currently, various methods have been proposed to manufacture such a metal panel (panel).

First, a method of manufacturing a building exterior material by applying an incision and then bending a corner portion of a rectangular panel was applied, which has a problem in that metal deformation occurs in the welded portion.

In addition, there is a method of manufacturing a building exterior material with fixed corners by fastening the remaining metal parts with rivets or bolts after bending each side after leaving extra metal on the side of the rectangular panel, which is not only expensive, There was an inconvenience in that the operator had to perform further operations such as fastening with rivets or bolts separately.

Moreover, in order to make the corner portion of the building exterior material firm, it may be manufactured by forming a non-bending portion at the corner of a square panel, but this is difficult to form integrally with the flange portion because it is necessary to form some degree of the non-bending portion. to be.

Therefore, when manufacturing the exterior material for construction using this current technology, there is a concern that the fastening of the corners may not be perfect, resulting in problems such as leaks and cracks.

Looking at the background technology to compensate for this problem, in the "Method of processing the corners of the metal panel" in Korean Patent Registration No. 10-0311936 (hereinafter referred to as 'document 1'), the edge edge of one side of the bent metal panel is left about 100 mm. Disclosed is a method of processing a corner by bending and fixing it closely to the pedestal, then rotating the roller from top to bottom in a vertical direction.

In the case of using the invention of Document 1, as shown in FIG. 1, a separate process for a corner is performed by tearing a metal panel using a separate process or processing a corner without performing a process such as chamfering (notching). Although it is unnecessary, the final process time is shortened, and there is an advantage that a uniform product can be produced. However, by pushing the metal using a roller, the thickness of the corner portion and the portion other than the corner cannot be uniformly formed by the shape of the roller. In addition, the process time is increased by the number of revolutions of the roller, and a precise process is required by cutting the metal piece into a bent shape.

Looking at other background technologies, in the Korean Patent Registration No. 10-1527006 (hereinafter referred to as 'document 2'), the construction panel and its manufacturing method, the airtight structures of the corners are formed together in the bending process for forming the side bends. Disclosed is an architectural panel capable of forming an airtight structure for corners without welding, and a method for manufacturing the same.

When using the invention of Document 2, as shown in Figure 2, the main panel portion between the two side bent portion and the airtight portion formed in an integral structure with the two side bent portions are deformed together during bending of the two side bent portions to finally By the way, there is an advantage of forming an airtight structure for the corner portion where the main panel portion and the two side bent portions meet, but a gap is generated between the first and second regions due to the end shape of the airtight portion, thereby causing corrosion of the panel by rainwater or the like. , As a building exterior material, there is a deterioration in function.

Looking at other background technologies, in the “Paper processing method of metal panel for construction” in Korean Patent Registration No. 10-0407587 (hereinafter referred to as “Document 3”), the metal panel is fixed to the lower mold and the upper mold, and the forming roller is moved up and down. Disclosed is a processing method for processing a corner by moving to.

When the technique of Document 3 is used, as shown in FIG. 3, there is an advantage in that separate welding or the like is unnecessary, and a separate molding and flange attachment are unnecessary by manufacturing the flange integrally, but the boundary surface by a roller Due to the formation of the overlapping boundary surfaces, corrosion of the ends of the boundary surfaces may occur due to rainwater or the like due to environmental changes due to the shape of the boundary surfaces, which is unsuitable as a building exterior material.

Looking at other background technologies, in the “Metallic Panel for Construction” of Korean Patent Registration No. 10-0889580 (hereinafter referred to as “Document 4”), a plurality of grooves meet each other by a roll-zipping method. Disclosed is a metal panel that is formed by being pressed in such a way that the groove is engaged inward and fastened vertically.

In the case of using the invention of Document 4, as shown in FIG. 4, even if a metal rolling phenomenon occurs at the corners by the roll-jipping method, there is an advantage that the corners are uniformly formed because it has an extra space cut off. Not only is it necessary to elaborately mold the groove so that it can be molded, but also there is a disadvantage in that the metal panel is deformed and unsuitable as a building exterior material due to rainwater entering the groove end due to environmental changes.

That is, the second corner portion 152 is pressurized by the pressing device, so that the fifth bent portion 150 is formed to protrude upward, and at the same time, the other side of the second extension portion 122 is pressed to protrude upward. The six bent portion 160 is formed, and the third bent portion 130 and the second extension portion 122 may be horizontal to each other, but is not limited thereto.

6) Step 6 (S160)

The sixth step (S160) is a step of performing a second partial cutting so that the end of the forming plate 100 subjected to the fifth step (S150) is beautiful, as shown in FIGS. 7 and 11.

In more detail, the fifth bending portion 150, the first edge portion 151, the second edge portion 152, or the sixth bending portion 160 of the rough forming plate 100 in the fifth step (S150). It is formed of a certain thickness by pressing and pushing the overlapping part of any one selected from the pressing device, and at the same time, the pushed part is the fifth bending part 150, the first corner part 151, and the second corner part 152. Alternatively, the sixth bent portion 160 may be formed to protrude upwardly at one end selected.

In order to remove this, the sixth step (S160) is performed, so that the final building exterior material manufactured is beautiful and can be formed with a certain width.

Optionally, when the sixth step (S160) is performed on the second corner portion 152, the width of the second edge 152 may be cut in the same manner as the sixth bending portion 160.

If, when the width of the sixth bent portion 160 is formed smaller than the fifth bent portion 150, the second corner portion 152 is a stepped shape formed to be flexibly connected to the other end of the fifth bent portion 150 It can be cut, but is not limited to this.

When the fifth bent portion 150 and the second corner portion 152 are formed by being connected in a stepped shape, when the final manufactured building exterior material is fixed to the outer wall, it is horizontal with the outer wall by the shape of the fifth bent portion 150 This can be easily installed as well as, when it is necessary to replace the final exterior building construction, there is an advantage that the operator can easily perform the replacement by the width of the second edge portion (152).

Optionally, in the sixth step (S160), one or more first coupling parts 123 may be formed on one side of the forming plate 100.

Preferably, the first extension portion 121 may be formed on both sides of the other side, but is not limited thereto.

That is, the first coupling portion 123 is formed so that the coupling member penetrates the molding plate 100 so that the final building exterior material can be firmly fixed to the outer wall.

If the first coupling portion 123 is not formed, a means for fixing the building exterior material including a structure or a device capable of fixing the building exterior material that is finally manufactured on one side of the molding plate 100 to the exterior wall is further provided. It can be included, but is not limited to this.

The building exterior material or sandwich panel manufactured in this way is not applied with a vertically pressing device such as a roller, and the edges are integrally formed smoothly to form a beautiful appearance. By pressing at a predetermined angle, rotation by a roller or the like can be used. It is manufactured by a process time shorter than the process produced by being pressed several times, and a gap that can be formed in the secondary bent portion 170 is not formed, so that a building exterior material can be manufactured without performing a separate process such as welding. There is an advantage.

Moreover, deformations such as thermal expansion and oxidation due to climate change and external stimuli are minimized, and durability is improved to reduce the incidence of leaks and corrosion, and the thickness of the building exterior material finally manufactured by molding at a predetermined angle It has the advantage of being formed to increase the strength.

The present invention relates to a building exterior material, and specifically, a gap that can be formed in the second bent portion 170 is not formed, so that it is possible to manufacture a building exterior material without performing a separate process such as welding. It is an invention.
