Description

A finishing member for sealing the gap between the ridge and the roof panel, its manufacturing method, and a building structure including the finishing member

The present invention relates to finishing members or finishing materials for building structures. In detail, it relates to a finishing member for sealing a gap between a ridge and a roof panel, a manufacturing method thereof, and a building structure including the finishing member.

Roof refers to a cover that covers the top of a building structure such as a house. The roof provides the function of protecting indoor space from external environments such as rain, wind, and sunlight. There are various types of roofs, but due to the characteristics of Korea's climate with high rainfall, some have sloping shapes such as gable roofs, hip roofs, and gambrel roofs to shed rainwater. There are a lot.

There are many different ways to install a roof according to the old method, but rafters extending in the direction of the slope (swing direction) of the roof centered on the top fidge, and/or in a direction parallel to the fidget. It is common for purlins, which extend to support the rafters, and additional collar ties, which connect the rafters to each other, to distribute the load among themselves and constitute a frame. Then, a roof panel consisting of a sandwich of insulation material and metal plates is placed on the roof frame to form the roof.

At this time, in a roof that is sloping on both sides, such as a gable roof, roof panels are arranged along the direction of the roof slopes on both sides, and as a result, a gap where a ridge exists is created between the roof panels. And to seal the gap, a member commonly called a ridge panel or upper ridge flashing is added.

In general, a roof panel extends along the direction of the roof slope and includes a plurality of ridges (mountains) arranged spaced apart in the perpendicular direction, that is, the ridge and purlin direction. Ridges in roof panels can improve the flexural strength of the panels. However, due to the ridge structure existing on the top of the roof panel, a gap inevitably occurs between the roof panel and the ridge panel. That is, a gap is created between the valley between the ridges of the roof panel and the ridge panel.

If the above gap is left unattended, it will not be able to sufficiently block the outside and indoor space, making it difficult to control indoor temperature and humidity, as well as allowing rain or wind to enter, and becoming a path for insects, etc. to enter. For this purpose, in the past, a roofing construction material called a crochet was inserted into the gap between the roof panel and the ridge panel.

However, Crosha is made of synthetic resin material and deterioration such as corrosion, distortion, and shrinkage occurs in the process of exposure to various external environments such as rain. As a result, problems such as the need to re-install Crosha after a certain period of time have elapsed after roof construction. There was. In relation to this, Patent Document 1 and Patent Document 2 make various attempts to seal the above gap without using a crochet.

Meanwhile, a significant amount of stress is applied to a roof that is always exposed to the external environment. For example, under conditions such as typhoons or strong winds, wind exerts drag on the roof panels and a gap occurs between each panel that makes up the roof. The lifting between these panels becomes more severe over time, eventually requiring the entire roof to be rebuilt. The structures disclosed in the Croshana patent documents above are concerned only with closing the gap between the roof panel and the ridge panel by inserting a structure of a shape corresponding to the gap shape.

Accordingly, from an architectural engineering perspective, the problem to be solved by the present invention is to seal the gap between the roof panel and the ridge panel while maintaining sufficient durability despite the harsh external environment, preventing the members constituting the roof from loosening over time, The goal is to provide a roof finishing member that can minimize the occurrence of gaps and gaps.

1 to 9, the building structure 1 according to this embodiment includes a roof panel 100, a roof finishing member 300 disposed on the roof panel 100, and a roof finishing member 300. It includes a disposed ridge panel 200.

The roof panel 100 may have a structure in which an insulating material and a metal plate are laminated. The material of the metal plate is not particularly limited, but may be a galvanized steel plate, etc. Although the present invention is not limited thereto, the roof panel 100 of the building structure 1 may be configured in the form of a gable roof including at least two roof panels 100 arranged in different slope directions (swing directions). there is. That is, the two roof panels 100 may be arranged in a symmetrical shape.

The roof panel 100 extends in the direction of the slope and may have a plurality of roof ridges 100p (or roof crests or roof ridges) arranged to be spaced apart in a direction perpendicular to the slope. Additionally, a roof valley 100v may be defined between the two roof ridges 100p that are closest to each other and spaced apart.

The ridge panel 200 may be disposed on the top of the roof panel 100 and configured to cover the gap between the two roof panels 100 at the top. The ridge panel 200 has a symmetrical shape and may include a first ridge panel portion 200a, a second ridge panel portion 200b, and a third ridge panel portion 200c. The first ridge panel portion 200a to the third ridge panel portion 200c may be formed by bending a single metal plate, but may be sequentially connected and formed as one body without physical boundaries. In addition, the first ridge panel portion 200a to the third ridge panel portion 200c may have different inclination angles. For example, the inclination angle of the second ridge panel portion 200b may be greater than the inclination angle of the first ridge panel portion 200a. That is, the second ridge panel portion 200b may be relatively closer to the vertical direction than the first ridge panel portion 200a. Additionally, the inclination angle of the third ridge panel portion 200c may be smaller than that of the second ridge panel portion 200b. That is, the third ridge panel portion 200c may be relatively closer to the horizontal direction than the second ridge panel portion 200b. The inclination angles of the first ridge panel portion 200a and the third ridge panel portion 200c may be the same or different from each other.

As a non-limiting example, the difference in inclination angle (eg, acute angle) between the first ridge panel portion 200a and the second ridge panel portion 200b may be about 30 degrees to 70 degrees, or about 40 degrees to 60 degrees. Additionally, the difference in inclination angle (eg, acute angle) between the second ridge panel portion 200b and the third ridge panel portion 200c may be about 30 degrees to 70 degrees, or about 40 degrees to 60 degrees.

The roof panel 100 and the ridge panel 200 having a plurality of roof ridges 100p may be arranged to at least partially contact each other. For example, the uppermost upper surface of the roof ridge 100p and the lower surface of the third ridge panel portion 200c of the ridge panel 200 may be in contact with each other. As described above, as the roof panel 100 has a roof valley 100v forming a lower level (height) than the roof ridge 100p, the upper surface of the roof valley 100v and the ridge panel 200, For example, the lower surfaces of the third ridge panel portion 200c may be spaced apart from each other to form a gap. The roof finishing member 300 according to this embodiment may be at least partially interposed or inserted between the roof panel 100 and the ridge panel 200 to seal the gap. Hereinafter, the roof finishing member 300 will be described in detail.

The roof finishing member 300 may have a shape extending approximately in the first direction (X). Additionally, one repeating unit (RU) may be repeated in the first direction (X). In example embodiments, a repeat unit (RU) may be repeated 2, 3, 4, or 12 times. Preferably, the repeating unit (RU) may be repeated 12 times so that 12 third inclined portions 330, which will be described later, protrude. In this specification, the first direction (X) refers to the direction in which the repeating unit (RU) of the roof finishing member 300 is repeated.

In order to install the roof finishing member 300, the worker climbs on the roof panel 100, inserts the roof finishing member 300 between the ridge panel 200 and the roof panel 100, and attaches them to the fixing member 400, such as It must be fixed using a piece. Since workers must work on the sloping roof panel 100 without separate safety devices, improving work convenience can be a very important factor. Conventionally used crochets had the problem that work was very cumbersome because one crochet had a shape corresponding to one or two roof valleys (100v). For example, in a building structure in the form of a gable roof with slopes on both sides, if 24 roof ridges (100p) are repeated, the process of inserting and fixing the crossshaft at least 24 times and at most 48 times is required.

Accordingly, in terms of improving work convenience, the inventor of the present invention proposes a roof finishing member 300 having a large number of roof ridges 100p and protrusions (i.e., third slopes 330) corresponding to the roof valleys 100v. The present invention was completed by focusing on the fact that the roof finishing member 300 can be constructed relatively easily when using .

In addition, since workers perform construction without safety devices on the sloping roof panel 100, if the weight of one roof finishing member 300 is too heavy, handling is difficult and the possibility of causing a safety accident increases. For this reason, the roof finishing member 300 may be made of a thin metal material that is light enough for one worker to carry and work with. At this time, if the length of the roof finishing member 300 is too long, there is a problem in that the roof finishing member 300 is vulnerable to bending deformation in the longitudinal direction. For this reason, conventional crochets were generally manufactured with a length corresponding to one or two roof valleys (100v). However, the roof finishing member 300 according to this embodiment is bent even when it has a length of about 2,800 mm to 3,200 mm, or about 2,900 mm to 3,100 mm, or about 3,000 mm in the longitudinal direction, that is, in the first direction (X). It can provide high handling convenience without losing weight. The maximum length (L1) of any one repeating unit (RU) in the first direction (X) may be about 230 mm to 270 mm, or about 240 mm to 260 mm, or about 250 mm. The fact that the roof finishing member 300 according to this embodiment has excellent bending strength despite having a relatively long length will be described in detail later along with the cross-sectional structure.

In an exemplary embodiment, the roof finishing member 300 includes, in its cross section, a first slope 310, a second slope 320, and a third slope 330, and a first bent part 391. ) and a second bent portion 392. In this specification, the cross-section refers to a plane perpendicular to the longitudinal direction of the roof finishing member 300, that is, the first direction (X). In other words, unless otherwise defined, a cross section may mean a plane to which the second direction (Y) and the third direction (Z) belong.

In cross-section, the first inclined portion 310 to the third inclined portion 330 are formed by bending one metal plate, but are sequentially connected and may be formed as one body without physical boundaries. Here, the gently or folded bent portion between the first inclined portion 310 and the second inclined portion 320 is referred to as the first bent portion 391, and the second inclined portion 320 and the third inclined portion are referred to as the first bent portion 391. The gently or folded portion between 330 may be referred to as a second bent portion 392. The first to third inclined portions 310 to 330 may have at least partially different inclination angles or inclinations. Of course, the

bent portions

391 and 392 are also formed integrally with the first to third inclined portions 310 to 330 .

The roof finishing member 300 including the first inclined portion 310 to third inclined portion 330, and the first bent portion 391 and the second bent portion 392 may include metal. For example, it may include galvanized steel sheet or be made of galvanized steel sheet.

First, the second inclined portion 320 may be located between the first inclined portion 310 and the third inclined portion 330. Additionally, at least the upper surface of the second inclined portion 320 may provide a plane space to which the first direction (X) and the second direction (Y) belong. That is, in this specification, the second direction Y refers to a direction substantially parallel to the width direction of the upper surface of the second inclined portion 320.

The second inclined portion 320 may include a 2-1 inclined portion 321 and a 2-2 inclined portion 322 that are stacked on each other. In addition, the 2-1 inclined part 321 is disposed on the upper part of the 2-2 inclined part 322, and the inner surface (lower surface of FIG. 6) of the 2-1 inclined part 321 and the 2-2 The inner surfaces of the inclined portions 322 (top surface in FIG. 6) may directly oppose or come into contact with each other.

In addition, the 1-2 inclined part 312 is disposed on the upper part of the 1-1 inclined part 311, and the inner surface (lower surface of FIG. 6) of the 1-2 inclined part 312 and the 1-1 The inner surfaces of the inclined portions 311 (top surface in FIG. 6) may directly oppose or come into contact with each other.

The first inclined portion 310 is a space into which a fixing member (not shown) (e.g., a second fixing member) is inserted when fixing the roof finishing member 300 and the ridge panel 200 on the roof panel 100. may be provided, but the present invention is not limited thereto. In addition, the first inclined portion 310 prevents the roof finishing member 300 from flowing down on the inclined roof panel 100 due to interference with the second ridge panel portion 200b of the ridge panel 200. You can.

In some embodiments, the length of the first inclined portion 310 in the inclined direction may be smaller than the length of the second inclined portion 320 in the inclined direction (i.e., the width in the second direction (Y)). .

The 1-1st inclined portion 311 and the 1-2nd inclined portion 312 may be connected to the first inclined portion bent portion 311v. That is, the 1-1 inclined portion 311, the first inclined portion bent portion 311v, and the 1-2 inclined portion 312 may be sequentially connected.

You can connect through (391). That is, the 1-2 inclined portion 312, the first bent portion 391, and the 2-1 inclined portion 321 may be sequentially connected. In other words, the bent or folded portion 312v between the 1-2 inclined portion 312 and the 2-1 inclined portion 321 may be defined as the first bent portion 391.

Through the first bent portion 391, the first inclined portion 310 and the second inclined portion 320 may form different inclined surfaces. The angle between the upper surfaces of the first inclined portion 310 and the second inclined portion 320, for example, the first obtuse angle θ1 , may be in the range of about 130 degrees to 160 degrees. Accordingly, the difference in inclination angle between the first inclined portion 310 and the second inclined portion 320 may be in the range of about 20 degrees to 50 degrees.

The third inclined portion 330 may be connected to the other end (right end in FIG. 6 ) of the second inclined portion 320 via the second bent portion 392.

The third inclined portion 330 may include a 3-1 inclined portion 331 and a 3-2 inclined portion 332 that are stacked on each other. In addition, the 3-1 inclined part 331 is disposed on the upper part of the 3-2 inclined part 332, and the inner surface (lower surface of FIG. 6) of the 3-1 inclined part 331 and the 3-2 The inner surfaces of the inclined portions 332 (top surface in FIG. 6) may directly oppose or come into contact with each other.

The third inclined portion 330 serves to seal the gap caused by the height difference between the roof ridge 100p and the roof valley 100v of the roof panel 100. At this time, one end of the third inclined part 330 (upper part in FIG. 6) is placed at a height corresponding to the upper surface of the roof ridge 100p, and the other end of the third inclined part 330 (lower part in FIG. 6) Can be placed at a height corresponding to the upper surface of the roof valley (100v).

In some embodiments, the length of the first inclined portion 310 in the inclined direction may be smaller than the length of the third inclined portion 330 in the inclined direction. Additionally, the length of the third inclined portion 330 in the inclined direction may be smaller or larger than the length of the second inclined portion 320 in the inclined direction.

The 3-1st inclined portion 331 and the 3-2nd inclined portion 332 may be connected to the third inclined portion bent portion 331v. That is, the 3-1st inclined portion 331, the third inclined portion bent portion 331v, and the 3-2 inclined portion 332 may be sequentially connected.

In an exemplary embodiment, the second bent portion 392 may have a multi-layer structure including a 2-1 bent portion 321v and a 2-2 bent portion 332v. The 2-1 inclined portion 321 and the 3-1 inclined portion 331 may be connected through the 2-1 bent portion 321v. That is, the 2-1 inclined portion 321, the 2-1 bent portion 321v, and the 3-1 inclined portion 331 may be sequentially connected. In other words, the bent or folded portion 321v between the 2-1 inclined portion 321 and the 3-1 inclined portion 331 may be defined as the 2-1 bent portion.

Additionally, the 3-2 inclined portion 332 and the 2-2 inclined portion 322 may be connected through the 2-2 bent portion 332v. That is, the 3-2 inclined portion 332, the 2-2 bent portion 332v, and the 2-2 inclined portion 322 may be sequentially connected. In other words, the bent or folded portion 332v between the 3-2 inclined portion 332 and the 2-2 inclined portion 322 may be defined as the 2-2 bent portion. And the 2-1 bent part 321v and the 2-2 bent part 332v that are stacked together may form the second bent part 392.

Through the second bent portion 392, the second inclined portion 320 and the third inclined portion 330 may form different inclined surfaces. The angle between the lower surfaces of the second inclined portion 320 and the third inclined portion 330, for example, the second obtuse angle θ2 , may be in the range of about 100 degrees to 130 degrees. Accordingly, the difference in inclination angle between the second inclined portion 320 and the third inclined portion 330 may be in the range of about 50 degrees to 80 degrees.

The above-described first inclined portion 310 and second inclined portion 320 are continuously connected along the longitudinal direction, that is, the first direction (X), and have substantially the same cross-sectional shape at any position in the first direction (X). You can have it. On the other hand, the third inclined portion 330 has a shape that protrudes from the first inclined portion 310, and a plurality of third inclined portions 330 may be spaced apart from each other. As described above, in a non-limiting example, when the repeating unit (RU) is repeated 12 times, the third inclined portion 330 may also have 12 protruding shapes.

At this time, the maximum length L2 of the third inclined portion 330 may be about 200 mm to 220 mm, or about 205 mm to 215 mm, or about 205 mm to 210 mm. Additionally, the minimum length L3 of the third inclined portion 330 may be about 140 mm to 160 mm, or about 145 mm to 155 mm, or about 150 mm to 155 mm. When the third inclined portion 330 has an approximately trapezoidal shape in plan view, the maximum length L2 of the third inclined portion 330 is the distance between the second inclined portion 320 and the third inclined portion 330. It is the length of the portion in the first direction (X), and the minimum length (L3) of the third inclined portion 330 may be the length of the end of the third inclined portion 330 in the first direction (X). . Although the present invention is not limited thereto, the minimum length L3 of the third inclined portion 330 may correspond to the width of the lowest end of the roof valley 100v of the roof panel 100.

Additionally, the shortest separation distance D2 between the third inclined portions 330 that are closest to each other in the first direction (X) may be in the range of about 35 mm to 50 mm, or about 40 mm to 45 mm. Although the present invention is not limited thereto, the shortest separation distance D2 between the third inclined portions 330 may correspond to the width of the top of the roof ridge 100p of the roof panel 100. Additionally, the maximum separation distance D3 between the third inclined portions 330 that are closest to each other may be in the range of about 80 mm to 110 mm, or about 90 mm to 100 mm.

Meanwhile, the inclined length of the third inclined portion 330 in the inclined direction may be in the range of about 30 mm to 65 mm. Here, the inclined length of the third inclined portion 330 may mean the length of the upper surface of the third inclined portion 330 at the cross-sectional view of FIG. 6. As the third inclined portion 330 has a sufficient inclined length, it can sufficiently cover the space between the roof ridge 100p and the roof valley 100v of the roof panel 100.

As described above, the roof finishing member 300 according to this embodiment may have a double-layer structure in its cross section. For example, when the roof finishing member 300 is manufactured by bending a metal plate having a thickness of about 0.4 mm to 0.6 mm, or about 0.45 mm to 0.55 mm, the first inclined portion 310 of the roof finishing member 300 , the maximum thickness of the second inclined portion 320 and the third inclined portion 330 may be in the range of about 0.8 mm to 1.2 mm, or about 0.9 mm to 1.1 mm. By keeping the maximum thickness of the

inclined portions

310, 320, and 330 within the above range, lightweighting of the roof finishing member 300 is achieved, and at the same time, the fixing member 400 is fixed through the roof finishing member 300. It can be done easily. This can increase the operator's work convenience. In particular, if the maximum thickness of the roof finishing member 300 exceeds the above range, or exceeds about 1.5 mm, special equipment may be required for insertion of the fixing member 400.

The maximum thickness of the roof finishing member 300 is very thin, and accordingly, the weight of the roof finishing member 300 is light, so that ease of handling by workers on the roof panel 100 can be increased. In addition, despite the thin thickness of the roof finishing member 300, the first inclined portion 310 to the third inclined portion 330, and the first bent portion 391 and the second bent portion 392 are visible in its cross section. ) has a double-layer structure at least partially, the bending strength of the roof finishing member 300 in the longitudinal direction increases, and bending deformation can be suppressed.

In particular, after various attempts by the inventor of the present invention, the portion bent to form the

inclined portions

310, 320, and 330 of the roof finishing member 300, that is, the first bent portion 391 and/or the second bent portion It was confirmed that when (392) has a double-layer structure, it is greatly helpful in improving the bending strength, and the present invention was completed.

That is, the cross-sectional view of FIG. 6 cut so that the third inclined portion 330 and the second bent portion 392 are expressed within a repeating unit (RU), and the third inclined portion 330 and the second bent portion 392 ) In the cross-sectional view of FIG. 7 cut so that ) is not expressed, the roof finishing member 300 according to this embodiment has the second bent portion 392 to have a double-layer structure, and the first bent portion 391 has a single-layer structure. It was designed to have a structure.

Meanwhile, the roof finishing member 300 according to this embodiment can be placed on the roof panel 100 and coupled using the fixing member 400 with the ridge panel 200 disposed on top of it.

For example, the first fixing member 400 penetrates the third ridge panel portion 200c of the ridge panel 200 and the second inclined portion 320 of the roof finishing member 300, and the roof panel 100 It can be inserted and fixed into the roof ridge (100p). In this case, the first fixing member 400 may sequentially completely penetrate the 2-1 inclined portion 321 and the 2-2 inclined portion 322.

For another example, the second fixing member (not shown) may be fixed by penetrating the second ridge panel portion 200b of the ridge panel 200 and the first inclined portion 310 of the roof finishing member 300. . In this case, the second fixing member may completely penetrate the 1-2 inclined portion 312 and the 1-1 inclined portion 311 sequentially.

Specifically, the third inclined portion 330 of the roof finishing member 300 may seal the space between the roof ridges 100p of the roof panel 100. For example, the third inclined bent portion 331v may contact the upper surface of the roof valley portion 100v.

Additionally, the second inclined portion 320 may be placed in contact with the uppermost end surface of the roof ridge 100p of the roof panel 100. That is, the lower surface of the second inclined portion 320, more specifically, the lower surface of the 2-2 inclined portion 322, is in contact with the upper surface of the roof ridge 100p, and the upper surface of the second inclined portion 320, more specifically, is in contact with the upper surface of the roof ridge 100p. As a result, the upper surface of the 2-1 inclined portion 321 may be in close contact with the lower surface (or inner surface) of the third ridge panel portion 200c of the ridge panel 200.

In addition, the first inclined portion 310 is at least partially spaced apart from the roof panel 100, and the upper surface of the first inclined portion 310, more specifically the upper surface of the 1-2 inclined portion 312, is a ridge panel ( It may be in close contact with the lower surface (or inner surface) of the second ridge panel portion 200b of 200). Accordingly, even when the roof panel 100 is disposed at an angle, the first inclined portion 310 is in close contact with the second ridge panel portion 200b, thereby preventing the roof finishing member 300 from flowing down due to gravity. .

At this time, at least some or all of the first inclined portion 310 to the third inclined portion 330 of the roof finishing member 300 has a double-layer structure, so that the roof finishing member 300 is maintained despite the harsh external environment. The fixation characteristics are improved, and the adhesion between the roof finishing member 300 and the ridge panel 200 is improved, thereby minimizing the occurrence of lifting, spreading, and clearance between members even over time after construction. This will be described in detail later with reference to FIG. 15.

That is, the lengths of the 1-1 slope portion and the 1-2 slope portion of the roof finishing member according to the above-described embodiment may be substantially the same or may have a length difference of about 20%. However, the 1-1 inclined portion 311 of the roof finishing member 302 according to the present embodiment has a shorter length than the 1-2 inclined portion 312, but the length of the 1-1 inclined portion 311 may be about 60% or less, or about 50% or less of the length of the first-second inclined portion 312.

However, the roof ridge (not shown) supports the 2-2 inclined portion 322 located on the lower side, and the fixing force by the fixing member is also stronger on the 2-2 inclined portion 322 than on the 2-1 inclined portion 321. Since the position of the 2-2 inclined portion 322 is fixed, an upward force, for example, the 2-1 inclined portion 321, is applied to the ridge panel ( It may take force to move to the (not shown) side. Accordingly, the second inclined portion 320 including the 2-1 inclined portion 321 is brought into closer contact with the back of the ridge panel, and even if time passes after construction, a gap between them does not occur or can be alleviated. there is.

Additionally, in a state where the position of the 3-2 inclined portion 332 is fixed, a force toward the upper surface (right direction as of FIG. 15) may be applied to the 3-1 inclined portion 331, and the time after construction Even after this, the third inclined portion 330 that seals the gap between the roof ridge and the roof valley of the roof panel can be prevented from collapsing inward.

Hereinafter, the present invention will be described in more detail through manufacturing examples of the present invention.

A roof finishing member having a cross section as shown in FIG. 6 was manufactured through the method described in FIGS. 10 to 13. In addition, a roof finishing member having a cross section as shown in FIG. 16 was manufactured through the method described in FIGS. 18 to 21.

The metal sheet used in manufacturing was a galvanized steel sheet, and the size of the metal sheet was 300 mm × 3,000 mm. The metal sheet was processed to a thickness of approximately 0.5 mm. The number of protrusions of the third inclined portion was set to 12. The length of one repeat unit was 250 mm. Then, one end of the manufactured roof finishing member was placed on a flower bed, and a photo was taken with the other end placed on the floor, and is shown in Figure 25. In Figure 25, the product on the right has the structure of Figure 6, and the product on the left has the structure of Figure 16.

Referring to Figure 25, it can be seen that although the total length of the roof finishing member is very long at 3,000 mm, the bending strength is excellent and bending deformation does not occur. This is because at least some of the bent parts have a double structure.

For comparison with the roofing member according to the present invention, a roofing member as shown in Figure 26 was manufactured. The metal sheet was set to have the same thickness as in the production example. However, unlike the present invention, rather than folding the metal sheet to form a double structure, the shape was realized by partially folding the metal sheet to have a single-layer structure. The length of the repeating unit was the same at 250 mm.

Referring to Figure 26, it can be seen that it cannot withstand the weight of two repeating units, that is, a length of about 500 mm, and is bent. In other words, as the metal sheet had a thin thickness, its bending strength in the longitudinal direction was very weak, and it could not be used because it was bent and irreversibly deformed even though it was only 500 mm long.

Although the description has been made above with a focus on embodiments of the present invention, this is merely an example and does not limit the present invention, and those skilled in the art will be able to understand the present invention without departing from the essential characteristics of the embodiments of the present invention. It will be apparent that various modifications and applications not exemplified above are possible.

Therefore, the scope of the present invention should be understood to include changes, equivalents, or substitutes of the technical ideas exemplified above. For example, each component specifically shown in the embodiments of the present invention can be modified and implemented. And these variations and differences in application should be construed as being included in the scope of the present invention as defined in the appended claims.
