Abstract
Description
[Technical Field]
[0001] The present invention relates to a wall panel structure, and more particularly to a wall panel structure for a steel plate storage shed or the like. [Background technology]
[0002] Conventionally, there have been products in which steel wall panels are combined to form storage sheds, garages, etc., and Patent Document 1 is an example of prior art in this technical field.
[0003] The storage shed in Patent Document 1 is constructed by joining multiple wall panels. The wall panel structure is formed into a roughly square box shape in cross section by a joining plate formed on one end of panel 101 and an engaging plate formed on the other end of the same panel 101. Specifically, as shown in Figure 5 (corresponding to Figure 4 of Patent Document 1), the first panel 101 has a folded portion 101a at one end of the panel that extends crosswise inward relative to the panel, a folded portion 101e at the other end of the panel that extends crosswise inward relative to the panel, a folded portion 101b that extends contiguous with the folded portion 101e and is positioned to cover the back side of the folded portion 101e, and a folded piece 101f that further extends from the folded portion 101b toward the wall panel.
[0004] The two folded portions 101a and 101e of both panels 101 are arranged one on top of the other, and each has a small diameter mounting hole 101c and a large diameter mounting hole 101d formed therein. The first panel 101 and the second panel 101 are joined by inserting a backing plate nut through the large-diameter mounting hole 101d and fastening it through a bolt 104 (see Figure 6). In Figure 5, there is a gap between the two folded-in portions 101a and 101e, but they will be tightly attached after the bolts are fastened. Also, to prevent rainwater from leaking, a packing is placed around the mounting hole 101d.
[0005] However, even if the folded-in portions 101a and 101e of the two panels 101 are tightly fastened by bolts, a very small gap will still be formed because the panels are made of steel plate, and during heavy rain or a storm, rainwater will seep into the gap between the folded-in portions 101a and 101e.
[0006] Figure 6 illustrates rainwater infiltration in the conventional technology. The symbol w indicates rainwater adhering to the outer surface of the wall panel 101. Some of this rainwater w penetrates into the gap between the folded-in sections 101a and 101e (which are actually sealed together, but are depicted enlarged for clarity) due to water pressure from rain from outside during heavy rain or a storm, capillary action, and other factors, leading to the infiltration of the box-shaped engaging section (arrow y1). The rainwater then exits the engaging section through the gap between the tip of the folded-in piece 101f and the panel board 101 (arrow y2). This creates a problem of wet items inside the storage shed. Furthermore, gaskets are used to prevent water from entering through the mounting holes 101c and 101d shown in Figure 5, but deterioration over time can allow rainwater to enter through the gaps in the gasket.

DETAILED DESCRIPTION OF THE INVENTION
[0012] Next, an embodiment of the present invention will be described with reference to the drawings. The following embodiment is a wall panel structure applied to a storage shed. Figure 2 shows two panel units 1,1. Each panel unit 1,1 is composed of a panel plate 2 made of corrugated steel plate with concave and convex shapes, a first engagement plate 3 and a second engagement plate 4 formed on both side edges of the panel plate 2, an upper edge plate 5 formed on the upper end of the panel plate 2, and a lower edge plate 6 formed on the lower end. The side walls of the storage shed are made up of wall panels each made up of a plurality of connected panel units 1. The means for connecting adjacent panel units 1, 1 are a first engagement plate 3 and a second engagement plate 4.
[0013] FIG. 3 shows the state in which the panel units 1, 1 shown in FIG. 2 are connected. The first engagement plate 3 of the panel unit 1 on the left side of the drawing is covered by the second engagement plate 4 of the panel unit 1 on the right side of the drawing, and they are connected by fastening with bolts. Hereinafter, this part may be referred to as the engagement portion 7.
[0014] As shown in FIG. 1, the first engagement plate 3 is board 2 The first engaging plate 3 has a U-shaped cross section and is made up of a folding plate portion 31 continuing from the folding plate portion 31, a back plate portion 32 continuing from the folding plate portion 31, and a free end plate portion 33 continuing from the back plate portion 32. The first engaging plate 3 is formed by bending one edge of the panel plate 2. The second engagement plate 4 is board 2 The second engaging plate 4 is formed in a U-shaped cross section by a folding plate portion 41 continuing from the folding plate portion 41, a back plate portion 42 continuing from the folding plate portion 41, and a free end plate portion 43 continuing from the back plate portion 42. The second engaging plate 4 is formed by bending the other end edge of the panel plate 2.
[0015] The folded plate portion 31 and the back plate portion 32 of the first engagement plate 3 are not connected at a right angle, but are connected via an inclined plate portion 34. The inclined plate portion 34 is inclined at approximately 45° to the back plate portion 32 and also at approximately 45° to the folded plate portion 31, but there are no particular restrictions on these angles, and they may be connected at any angle as long as the water passage space 10, described below, can be sufficiently secured.
[0016] The connection between the folded plate portion 41 and the back plate portion 42 of the second engagement plate 4 intersects at a right angle, and the inclined plate portion 34 of the first engagement plate 3 faces this corner, forming a space with a triangular cross section between them. This space becomes the water flow space 10. Note that the intersection angle between the folded plate portion 41 and the back plate portion 42 does not need to be an exact right angle; it may be an angle slightly smaller or larger than a right angle.
[0017] The first engagement plate 3 and the second engagement plate 4 are connected by bolts 8, with insertable plate nuts 9 passing through insertion holes formed in the back plate portions 32 and 42 of each of the engagement plates (see also reference numerals 8 and 9 in FIG. 3). In this embodiment, the back plate portions 32 and 42 are connected using insertable plate nuts 9, but the plate portions may also be fastened to each other by a method of forming screw holes in the back plate portion 32 by burring or the like, or by a combination of bolts and nuts. When the back plate portions 32 and 42 are connected in this manner using bolts 8, the first engagement plate 3 and the second engagement plate 4 can be firmly connected to each other. In this engagement portion 7, the bolt engagement position through which the bolt 8 is inserted is spaced apart from the water passage space 10 through which rainwater flows, thereby preventing rainwater from entering the storage shed through the bolt insertion hole.
[0018] The folding plate portions 31, 41 of the first engaging plate 3 and the second engaging plate 4 are both bent at approximately a right angle to the panel plate 2 of the panel unit 1. On the other hand, the free end plate portions 33, 43 of both engaging plates 3, 4 extend inclined toward the panel plate 2 at approximately the same inclination angle relative to the panel plate 2. The inclination angle relative to the panel plate 2 can be selected arbitrarily between about 85° and 50°.
[0019] As shown in FIG. 3, when connecting a plurality of panel units 1, the first engagement plate 3 is covered with the second engagement plate 4 before being joined. Considering this covering connection form, the angle of inclination of the free end plate portion 33 relative to the panel plate 2 can be made smaller by about 1 to 5 degrees than the angle of inclination of the free end plate portion 43. In this case, the gap between the folded plate portions 31, 41 can be made tighter when the second engagement plate 4 is placed over the first engagement plate 3 and then joined.
[0020] 1, when the first engagement plate 3 and the second engagement plate 4 are joined, the inclined surface of the free end plate portion 43 of the second engagement plate slides over the inclined surface of the free end plate portion 33 of the first engagement plate, and the mutual guiding action brings them into close contact with each other, leaving no gaps. This guiding action also makes it easier to assemble the two panel units 1, 1 together.
[0021] Next, the rainwater intrusion prevention function of this embodiment will be described with reference to FIG. In the figure, w represents rainwater, represented by small dots. In conditions with heavy rainfall and strong wind pressure, such as during a typhoon, rainwater w not only adheres to the outer surface of panel plate 2, but also penetrates through the gap between the two folded plate portions 31, 41. Although folded plate portions 31, 41 are normally in close contact, because they are steel plates in close contact with each other, very small gaps are unavoidable (note that the gaps are shown enlarged in Figure 4), and rainwater penetrates due to the water pressure of rain from outside the warehouse during heavy rain or a storm, capillary action, etc.
[0022] When the rainwater that has entered in this way reaches the water passage space 10, the surface tension does not act in the large water passage space 10, so the rainwater falls downward by gravity. The rainwater then drains to the ground surface through holes formed in the lower frame members that connect the wall panels. Therefore, there is no need for separate waterproofing treatment using packing or the like. As described above, the wall panel structure of this embodiment allows rainwater to flow downward through the water passage space 10 and be discharged to the ground, preventing items stored in the storage shed from getting wet. [Industrial Applicability]
[0023] The present invention is not limited to the storage shed described above, but can also be used for box-shaped metal products used outdoors, such as garages and LP gas container storage facilities. [Explanation of symbols]
