Description

Technical Field

[0001] The present invention relates to a structure for connecting a plurality of foamed resin panel bodies, which can be used for various structures and the like.

Background Art

[0002] As an example of a structure formed by connecting a plurality of foamed resin panel bodies, there is an assembled so-called dome house that forms a hemispherical living space inside (see, for example, Patent Documents 1-2).

[0003] The foamed resin panel body in Patent Document 1 is a curved surface fan-shaped member (dome pieces 10 to 19) having a large size that integrally forms a part of the ceiling surface divided in the circumferential direction and a part of the side wall surface divided in the circumferential direction. The panel body in Patent Document 2 is a flat triangular member (plate 3) having a small size that forms a part of the ceiling surface or a part of the side wall surface.

[0004] The connection structure of the plurality of foamed resin panel bodies in Patent Document 1 is to connect the upper parts of the tips of the dome pieces to each other with a top joint, and to adhere and fasten the stepped joint surfaces of the dome pieces adjacent in the circumferential direction with a fastener.

[0005] The connection structure of the plurality of foamed resin panel bodies in Patent Document 2 is to form a triangular angle member unit with three angle members arranged in a plane, provide a connection member at the vertex part of the angle member unit to connect the adjacent angle member units, and mount the plate so that the peripheral edge and the end surface of one surface of the flat triangular plate are along the angle member (FIG. 3 of Patent Document 2).

Patent Document 1

Patent Document 2

[0007] In the conventional interconnected structure of multiple foamed resin panels described above, if the foamed resin panels are made into large, curved fan-shaped members as in Patent Document 1, a very large, specialized molding machine is required, which increases the manufacturing cost of the panels.

[0008] The connecting structure of multiple foamed resin panels described in Patent Document 1 requires steps such as applying adhesive to one or both of the stepped joint surfaces of adjacent dome pieces in the circumferential direction, bringing the stepped joint surfaces of adjacent dome pieces in the circumferential direction into contact with each other, and attaching fasteners to fasten them. As a result, the construction is time-consuming and increases construction costs.

[0009] On the other hand, when a foamed resin panel is made into a small, planar triangular member as described in Patent Document 2, a special molding machine is not required, and therefore the manufacturing cost of the panel does not increase.

[0010] However, the connecting structure of multiple foamed resin panels described in Patent Document 2 requires the angle material unit formed by three angle materials and the connecting member, and the assembly work is time-consuming, thus increasing manufacturing and construction costs.

[0011] The present invention aims to reduce manufacturing and construction costs in a connecting structure for multiple foamed resin panels. [Means for solving the problem]

[0012] A connecting structure for multiple foamed resin panel bodies according to a first aspect of the present invention comprises multiple foamed resin panel bodies and multiple connecting members. The panel bodies have a planar polygonal shape, and the connecting members are straight rod-shaped. Multiple engagement holes, which are blind holes, are formed on the connecting end faces, which are the end faces that abut when connecting the multiple panel bodies, extending in a direction substantially perpendicular to the connecting end face, spaced apart in a direction along the edge connected to the connecting end face. In addition, slits connected to the engagement holes are formed on the surface of the panel bodies, with a width narrower than the diameter of the engagement holes. The connecting members have an outer diameter that fits into the engagement holes. When connecting the multiple panel bodies, with the connecting end face of one panel body in contact with the connecting end face of the other panel body, the engagement holes of one panel body connect with the engagement holes of the other panel body, and the slits of one panel body connect with the slits of the other panel body. The connecting member is pushed into the engagement hole through the slit, and with the connecting member positioned in the engagement hole, one panel body and the other panel body are connected in a state of contact.

[0013] A connecting structure for a plurality of foamed resin panel bodies according to a second aspect of the present invention is, in the connecting structure for a plurality of foamed resin panel bodies according to a first aspect, wherein all or part of the three or more connecting end faces of the planar polygonal panel body are inclined planes that form an angle with the surface of the panel body that is not a right angle.

[0014] A connecting structure for multiple foamed resin panel bodies according to a third aspect of the present invention comprises multiple foamed resin panel bodies and multiple connecting members. The panel bodies have a planar polygonal shape, and the connecting members are straight rods. When the multiple panel bodies are connected while spaced apart, multiple blind engagement holes are formed on the connecting end faces, which are the end faces facing each other, extending in a direction substantially perpendicular to the connecting end faces, spaced apart in a direction along the edge connected to the connecting end faces. Additionally, slits connected to the engagement holes are formed on the surface of the panel bodies, with a width narrower than the diameter of the engagement holes. The connecting members have an outer diameter that fits into the engagement holes and a length that is more than twice the depth of the engagement holes. When connecting multiple panels while they are spaced apart, the connecting end face of one panel and the connecting end face of the other panel are spaced apart and facing each other, the engagement hole of one panel and the engagement hole of the other panel face each other, and the end of the slit of one panel and the end of the slit of the other panel face each other. The connecting member is pushed from the slit into the engagement hole, and with the connecting member positioned in the engagement hole, one panel and the other panel are connected while they are spaced apart.

[0015] A connecting structure for multiple foamed resin panel bodies according to a fourth aspect of the present invention comprises multiple foamed resin panel bodies and multiple connecting members. The panel bodies are rectangular in shape, and the connecting members are straight rods. Multiple engagement holes are formed on the connecting end faces, which are the end faces that abut when connecting the multiple panel bodies, extending in a direction substantially perpendicular to the connecting end faces and penetrating the panel bodies, spaced apart in a direction along the edges connected to the connecting end faces. Additionally, slits connected to the engagement holes, narrower in width than the diameter of the engagement holes, are formed on the surface of the panel bodies, extending between opposite sides. The connecting members have an outer diameter that fits into the engagement holes and a length of at least twice the length of the slits. Multiple panel bodies are pushed into the multiple connecting members, which are installed parallel to each other, so that the connecting members enter the engagement holes through the slits, and the multiple panel bodies are connected with the connecting members positioned within the engagement holes. [Effects of the Invention]

[0016] According to the connection structure of a plurality of foamed resin panel bodies according to the present invention, since the foamed resin panel bodies are planar polygonal shapes and no special molding machine is required, the manufacturing cost of the panel bodies does not increase. Further, since the connecting material is a straight rod shape and thus easy to mold, the manufacturing cost of the connecting material does not increase.

[0017] On the connecting end surface of the panel body, a plurality of engaging holes extending in a direction substantially orthogonal to the connecting end surface are formed, and on the surface of the panel body, a slit connected to the engaging hole and having a width narrower than the hole diameter of the engaging hole is formed. By pushing the connecting material having an outer diameter that fits into the engaging hole into the engaging hole of the panel body, a plurality of the panel bodies can be easily connected.

[0018] Therefore, in the connection structure of a plurality of foamed resin panel bodies, the manufacturing cost and the construction cost can be reduced.

Embodiments for Carrying out the Invention

[0020] Hereinafter, embodiments according to the present invention will be described based on the drawings.

[0021] In an embodiment of the present invention, a view of the foamed resin panel body as seen toward its surface is taken as a front view.

[0022] [Foamed Resin Panel Body] The panel body 1 according to the embodiment of the present invention shown in FIG. 1 is made of a foamed resin such as, for example, foamed polystyrene (PS), foamed polyurethane (PUR), or foamed polyolefin (PE, PP, etc.), is flexible, and is excellent in cushioning properties, heat insulating properties, and light weight. The panel body 1 is, for example, rectangular in plan view, and has engaging holes 3 and slits 4.

[0023] The engaging holes 3 are provided on a connecting end face C, which is an end face that abuts or faces when connecting a plurality of panel bodies 1, so as to extend in a direction substantially orthogonal to the connecting end face C, and in the example of FIG. 1, they are blind holes. The engaging holes 3 are formed in a plurality at intervals in a direction along the side D connected to the connecting end face C, and in the example of FIG. 1, two are formed for each connecting end face C. The connecting end face C is a plane, and since the panel body 1 is rectangular in plan view, there are four connecting end faces C on the panel body 1.

[0024] The slit 4 is formed on the surface 1A of the panel body 1 so as to connect to the engagement hole 3, and its width is smaller than the diameter of the engagement hole 3.

[0025] [Connecting material] The connecting member 2 shown in Figures 3-5, 3-8, and 3-10-11 is made of, for example, wood, resin, or metal, and has high rigidity. The connecting member 2 is, for example, a round bar or round pipe, and is in the shape of a straight rod. The connecting member 2 has an outer diameter that fits into the engagement hole 3.

[0026] [Connecting structure of multiple foamed resin panels] The structure for connecting the two panel bodies 1,1 shown in Figure 2 will be described. An example of connecting structure A for the foamed resin panel bodies 1,1 is shown in Figure 3-4.

[0027] As shown in Figure 2, when two spaced-apart panel bodies 1,1 are brought closer together from the state shown in Figure 2, and the connecting end faces C,C of the two panel bodies 1,1 are brought into contact, the engagement hole 3 of one panel body 1 connects with the engagement hole 3 of the other panel body 1, and the slit 4 of one panel body 1 connects with the slit 4 of the other panel body 1.

[0028] In this state, as shown in Figure 3, each of the two connecting members 2 is pushed into the engagement holes 3,3 through the slits 4,4, and with the connecting members 2,2 positioned in the engagement holes 3,3, one panel body 1 and the other panel body 1 are connected in contact. The length of the connecting member 2 shown in Figure 3 is approximately the same as the length in the depth direction of the engagement holes 3,3 connected in the state shown in Figure 3 with the connecting end faces C,C in contact (twice the depth of the blind engagement hole 3).

[0029] In the connecting structure A shown in Figure 3, from a state where two panel bodies 1,1 are connected as shown in Figure 3, the connecting members 2,2 can be used as guides to stably and easily move the two panel bodies 1,1 in parallel to create a gap. Therefore, for example, after applying adhesive to one of the connecting end faces C,C, the gap can be closed using the connecting members 2,2 as guides, and it can be easily held in place until the adhesive hardens. By bonding the contacting connecting end faces C,C in this way, the connection strength can be improved.

[0030] As shown in Figure 2, when the connecting end faces C, C of the two panel bodies 1, 1 are spaced apart and facing each other, the engagement hole 3 of one panel body 1 faces the engagement hole 3 of the other panel body 1, and the end of the slit 4 of one panel body 1 faces the end of the slit 4 of the other panel body 1.

[0031] In this state, as shown in Figure 4, two connecting members 2, each longer than the connecting member 2 in Figure 3 and having a length exceeding twice the depth of the blind-hole engagement hole 3, are pushed into the engagement holes 3, 3 through the slits 4, 4, and the connecting members 2, 2 are positioned in the engagement holes 3, 3, thereby connecting one panel body 1 to the other panel body 1 while spaced apart. In the connecting structure A shown in Figure 4, spaces can be easily created at appropriate locations in the structure.

[0032] [First modified example of a foamed resin panel] The panel body 1 of the first modified example shown in Figure 5 is triangular in shape. In the triangular panel body 1, multiple blind engagement holes 3 are formed on the connecting end face C, extending in a direction substantially perpendicular to the connecting end face C, and slits connected to the engagement holes 3 are formed on the surface 1A of the panel body 1, with a width narrower than the diameter of the engagement holes 3. Since the connecting end face C is a plane and the panel body 1 is triangular in shape, the panel body 1 has three connecting end faces C.

[0033] The connecting structure A of the panel bodies 1,1 in the first modified example shown in Figure 5 is the same as the connecting structure A shown in Figure 3. In Figure 5, the connecting end faces C,C of the two panel bodies 1,1 are in contact, and the engagement hole 3 of one panel body 1 is connected to the engagement hole 3 of the other panel body 1, as is the slit 4 of one panel body 1 and the slit 4 of the other panel body 1.

[0034] In this state, as shown in Figure 5, each of the two connecting members 2 is pushed into the engagement holes 3,3 through the slits 4,4, and with the connecting members 2,2 positioned in the engagement holes 3,3, one panel body 1 and the other panel body 1 are connected in contact with each other.

[0035] The shape of panel 1 is not limited to a planar rectangular or planar triangular shape, but can be any planar polygon.

[0036] [Second modified example of a foamed resin panel] The second modified panel body 1 shown in Figure 6-7 is rectangular in shape, with the connecting end face C being an inclined plane IP. That is, the angle G (Figure 7) between the connecting end face C and the surface 1A of the panel body 1 is not a right angle, but rather approximately 95° to 120°. Therefore, as shown in Figure 7, the panel body 1 is trapezoidal in side view.

[0037] The connecting structure A of the panel bodies 1,1 in the second modified example shown in Figure 8 is the same as the connecting structure A shown in Figure 3. In Figure 8, the connecting end faces C,C of the two panel bodies 1,1 are in contact, and the engagement hole 3 of one panel body 1 is connected to the engagement hole 3 of the other panel body 1, as is the slit 4 of one panel body 1 being connected to the slit 4 of the other panel body 1.

[0038] In this state, as shown in Figure 8, the connecting member 2 is pushed into the engagement holes 3,3 through the slits 4,4, and with the connecting member 2 positioned in the engagement holes 3,3, one panel body 1 and the other panel body 1 are connected in contact. The connected panel bodies 1,1 are not flat because the connecting end face C is an inclined plane IP, but rather form a mountain shape as the panel bodies 1,1 intersect and contact at an angle, as shown in Figure 8, so that the panel bodies 1,1 can form a convex or concave portion.

[0039] In the rectangular panel body 1 shown in Figure 6-7, all four connecting end faces C are inclined plane IPs, but only a portion of the connecting end faces C may be inclined plane IPs. That is, if the polygonal panel body 1 is an N-sided (N is an integer greater than or equal to 3)-sided panel, it has N connecting end faces C, and all of them (N) may be inclined plane IPs, or only a portion of them may be inclined plane IPs.

[0040] [Third modified example of a foamed resin panel] The panel body 1 of the third modified example shown in Figure 9 is rectangular in shape, and the engagement holes 3 are formed in a grid pattern as through holes, rather than blind holes like the engagement holes 3 of the panel body in Figure 1. The slits 4 formed on the surface 1A that connect to the through-hole engagement holes 3 extend between opposite sides E1, E2 or between opposite sides F1, F2, and the slits 4,... are also formed in a grid pattern.

[0041] The length L0 of the connecting member 2 shown in Figure 10 is at least twice the length of the slit 4 (length of sides F1, F2) L1 or the length of the slit 4 (length of sides E1, E2) L2 (see Figure 9). Multiple connecting members 2 are used; for example, in the example in Figure 10, two connecting members 2,2 are installed in parallel.

[0042] The connecting structure B of the third modified panel body 1,1 shown in Figure 10 will now be described. The connecting members 2,2 shown in Figure 10 are, for example, erected on the ground or floor, or installed horizontally on the ceiling, and their positions are stably maintained. With the connecting members 2,2 installed in the appropriate positions in this manner, for example, the lower panel body 1 in Figure 10 is pushed in so that the connecting members 2,2 enter the engagement holes 3,3 through the slits 4,4, to achieve the state shown in Figure 10. Next, the upper panel body 1 in Figure 10 is moved as indicated by the arrow and pushed in so that the connecting members 2,2 enter the engagement holes 3,3 through the slits 4,4. As a result, the upper and lower panel bodies 1,1 are connected in a contact state.

[0043] The direction in which the panel body 1 is attached to the connecting members 2,2 may be opposite to the direction of the arrow in Figure 10, and the direction in which the upper and lower panel bodies 1,1 are attached to the connecting members 2,2 may be changed in Figure 10.

[0044] This connecting structure B of multiple foamed resin panels allows for the easy formation of flat surfaces such as walls, ceilings, or fences using multiple panel bodies 1 and multiple connecting members 2.

[0045] [Fourth modified example of a foamed resin panel] The fourth modified panel body 1 shown in Figure 11 shows an example in which some of the engagement holes 3 and slits 4 formed in the panel body 1 in Figure 9-10 have been eliminated. That is, the engagement holes 3,3, which are through holes connecting the connecting end face C connected to side F1 to the connecting end face connected to side F2, have been eliminated. Consequently, the slits 4,4 connected to these engagement holes 3,3 have also been eliminated. Therefore, the slits 4 formed on the surface 1A to connect to the engagement holes 3, which are through holes, extend between opposite sides E1 and E2 and are in a parallel straight line.

[0046] The connecting structure B of the panel bodies 1,1 in the fourth modified example shown in Figure 11 is the same as the connecting structure B of the panel bodies 1,1 in the third modified example shown in Figure 10. The connecting structure B allows for the easy formation of a wall, ceiling, or flat surface such as a fence using multiple panel bodies 1 and multiple connecting members 2.

[0047] In the multiple foamed resin panel body connecting structures A and B according to the embodiments of the present invention described above, the connecting strength can be changed by changing the material, foaming ratio, thickness of the foamed resin panel body 1, the diameter and length of the engagement hole 3, the width of the slit 4, the material and diameter of the connecting material 2, and whether or not the connecting end faces C, C that come into contact are bonded. This increases the design freedom to satisfy the required connecting strength.

[0048] [Effects and Effects] According to the connecting structures A and B of multiple foamed resin panels according to embodiments of the present invention, the foamed resin panel 1 has a planar polygonal shape and does not require a special molding machine, thus keeping the manufacturing cost of the panel 1 low. Furthermore, since the connecting material 2 is in the shape of a straight rod, it is easy to mold, thus keeping the manufacturing cost of the connecting material 2 low.

[0049] Multiple engagement holes 3 are formed on the connecting end face C of the panel body 1, extending in a direction substantially perpendicular to the connecting end face C. Slits 4 connected to the engagement holes 3 are formed on the surface 1A of the panel body 1, and their width is narrower than the diameter of the engagement holes 3. Multiple panel bodies can be easily connected by pushing a connecting member 2 having an outer diameter that fits into the engagement holes 3 into the engagement holes 3 of the panel body 1.

[0050] Therefore, manufacturing and construction costs can be reduced in the connecting structures A and B of multiple foamed resin panels.

[0051] All embodiments described above are illustrative and not limiting. Various improvements and modifications can be made without departing from the scope of the present invention. [Explanation of Symbols]
