[0003] Japanese Unexamined Patent Publication No. Hei 10-194166

[0004] Heavy loads may be loaded in the cargo compartment, and large vibrations may be applied to the cargo compartment when the truck is traveling. For this reason, the connection structure adopts a structure using the adhesive and the wedge member. Therefore, the work is performed on the truck for assembling the cargo compartment, and it is necessary to accurately perform the adhesive application work, the work of bringing the panel coated with the adhesive into close contact with the connection member, and the insertion work of the wedge member.

[0005] For this reason, it may take a long time to assemble a compartment such as a cargo compartment. In addition, it is necessary to accurately perform each of the above operations to ensure the strength of the compartment. Therefore, it takes time to assemble the compartment. There is a need for a panel assembly that allows panels to be robustly assembled with less labor and disassembled with less labor.

[0008] A panel assembly according to the first embodiment is described below with reference to the drawings. This panel assembly is used for rooms such as prefabricated cargo compartments (containers) and prefabricated houses shown in Figure 1. The room has a floor panel 3, a front panel not shown in Figure 1, a pair of side panels 5, a rear panel 6, and a roof panel 7. The floor panel 3 is placed and / or fixed on a predetermined mounting surface.

[0009] As an example of panel assembly, a panel assembly in which a rear panel 6 and a roof panel 7 are connected will be described. As shown in Figure 2, this panel assembly has a rear panel 6 as a first panel, and a first member 10 that is provided on the end of the rear panel 6 that constitutes the upper edge (first edge) 6a and extends along the upper edge 6a, and is long in the direction along the upper edge 6a. The panel assembly also has a roof panel 7 as a second panel, and a second member 20 that is provided on the end of the roof panel 7 that constitutes the rear edge (first edge) 7a and extends along the rear edge 7a, and is long in the direction along the rear edge 7a.

[0010] In this embodiment, the first member 10 is made of aluminum and is formed by extrusion molding. The second member 20 is also made of aluminum and is formed by extrusion molding. Therefore, the following parts of the first member 10 and the following parts of the second member 20 have the same cross-sectional shape over their entire or substantially entire longitudinal direction, except for parts that have undergone post-processing such as cutting or drilling after extrusion molding. For this reason, the explanation later, for example, that it is provided over the entire longitudinal direction of the first member 10, means that it is provided over the entire first member 10 except for the parts that have undergone post-processing. In this embodiment, the longitudinal direction of the first member 10 and the longitudinal direction of the second member 20 are parallel or substantially parallel.

[0011] As shown in Figure 2, the panel assembly has an engaging projection 11 that protrudes from the first member 10 in one direction along the Z-axis (Z-direction) and is provided along the entire longitudinal direction of the first member 10. The panel assembly also has an engaging recess 21 formed on the second member 20 and provided along the entire longitudinal direction of the second member 20. As shown in Figure 2, the engaging projection 11 can be inserted into the engaging recess 21 in the Z-direction. In the connection between the rear panel 6 and the roof panel 7, the longitudinal direction of the first member 10 and / or the second member 20 is along the X-axis (X-direction), and the Y-axis is perpendicular to the Z-axis and X-axis.

[0012] In this embodiment, the Z direction is along the first panel and perpendicular to the X direction, but the Z direction may also be oblique to the first panel. For example, the Z direction may be tilted 45° relative to the rear panel 6, in which case the Z-axis arrow shown in Figure 2 rotates 45° counterclockwise around the X axis. If the engaging recess 21 is also rotated 45° counterclockwise in Figure 2, it can achieve the same function and effect as when the engaging projection 11 extends in the Z direction, as will be described later.

[0013] As shown in Figure 2, the panel assembly has a rod-shaped member 30 that is inserted in the X direction into the space S between the engaging projection 11 inserted into the engaging recess 21 and the engaging recess 21, and the rod-shaped member 30 is long in the X direction. The panel assembly also has a first engaging surface 12 that is provided on the tip side of the engaging projection 11 and extends along the entire longitudinal direction of the first member 10, and engages with the inserted rod-shaped member 30 from one side in the Z direction (from above in Figure 2). In this embodiment, the first engaging surface 12 is inclined at 30° or more with respect to the Y axis, as shown in Figure 2.

[0014] Furthermore, the panel assembly has a second engagement surface 22 that is provided in the engagement recess 21 over the entire length of the second member 20 and engages with the rod-shaped member 30 from the other side in the Z direction (downward in Figure 2). In this embodiment, the second engagement surface 22 extends substantially parallel to the Y axis, as shown in Figure 2 and other figures.

[0015] As shown in Figure 2, the panel assembly has a plurality of pressing members 40 that press the inserted rod-shaped member 30 against the engaging projection 11. In this embodiment, the pressing members 40 are screw members such as hex socket set screws and bolts, and the rod-shaped member 30 is pressed against the engaging projection 11 by the plurality of pressing members 40. The second member 20 is provided with a plurality of female screw holes 20a at intervals in its longitudinal direction (depth direction in Figure 2), and each of the plurality of pressing members 40 is screwed into the plurality of female screw holes 20a. By rotating the plurality of pressing members 40 in the tightening direction, the rod-shaped member 30 is pressed against the engaging projection 11 by the plurality of pressing members 40.

[0016] The first member 10 is fixed to the upper edge 6a of the rear panel 6, which serves as the first panel, using a well-known fixing means, which includes fasteners including bolts, adhesives, etc. The second member 20 is fixed to the rear edge 7a of the roof panel 7, which serves as the second panel, using a well-known fixing means, which includes fasteners including bolts, adhesives, etc. In this embodiment, the first member 10 and the second member 20 are provided with recesses 10b and 20b for fixing, and the upper edge 6a and rear edge 7a are inserted into the recesses 10b and 20b, respectively, before the fixing is performed.

[0017] The panels 3, 5, and 7 in this embodiment are laminated panels having a structure in which both sides of a plastic plate member in the thickness direction are covered with thin aluminum plates, and the plate member is made of foamed urethane or the like. Panels with other laminated structures, plate members without a laminated structure, etc., can also be used as panels 3, 5, and 7. In particular, the floor panel 3 can be made from a wooden board, a metal plate, etc. The rear panel 6 has a large opening in the center of a panel similar to panels 5 and 7, and two doors 8 are attached to this opening (Figure 1). Windows or the like may be provided instead of the doors 8. Panels 5 and 7 may also be provided with doors, windows, etc. in a similar manner.

[0018] Panels 3, 5, 6, and 7 may also be made of metal plates in a corrugated or flat shape. In this case, panels 3, 5, 6, and 7 are fixed to the first member 10 and the second member 20 by well-known fixing means, which include fastening members including bolts, welding, etc. The thickness dimensions of panels 3, 5, and 7 in this embodiment are several tens of mm, but the thickness dimensions may also be around 10 mm, and other dimensions may also be used. The dimensions (thickness dimensions) of panels 5 and 6 as the first panels in the direction along the Y axis (Y direction) are 5 mm to 50 mm, and the dimensions (thickness dimensions) of roof panel 7 as the second panel in the direction along the Z axis (Z direction) are 5 mm to 50 mm, but even if the values ​​are outside this range, the effects described later may be achieved depending on the conditions.

[0019] In this embodiment, the rod-shaped member 30 inserted into space S has a first surface 31 facing one direction in the Z direction and a second surface 32 facing the other direction in the Z direction, as shown in Figure 3. The rod-shaped member 30 inserted into space S also has a third surface 33 facing one direction in the Y direction and the side of the engaging projection 11, and a fourth surface 34 facing the other direction in the Y direction. A rod-side inclined surface (rod-side engaging portion) 35 is provided between the first surface 31 and the third surface 33, and the rod-side inclined surface 35 is inclined at 30° or more with respect to the Y axis, as shown in Figure 3. When the first surface 31 or the second surface 32 is arranged substantially parallel to the Y axis, the rod-side inclined surface 35 is also inclined at 30° or more with respect to the first surface 31 or the second surface 32. In this embodiment, substantially parallel includes the angle difference between the two being 10° or less, and more preferably 6° or less.

[0020] In this embodiment, as shown in Figure 3, the first engagement surface 12 is the side surface of a recess 11a provided on the engagement projection 11 that is recessed toward one side in the Y direction. The recess 11a is provided along the entire longitudinal direction of the first member 10. The recess 11a also forms the side surface opposite to the first engagement surface 12 and has a facing surface 13 that is opposite to the second surface 32 of the rod-shaped member 30 in the Z direction, as shown in Figure 3. The recess 11a has a bottom surface 14 that is opposite to the third surface 33 of the rod-shaped member 30 in the Y direction, as shown in Figure 3.

[0021] In this embodiment, the second engagement surface 22 is a side surface of the recess 21a located within the engagement recess 21 and recessing toward the other side in the Y direction. The recess 21a extends over the entire longitudinal direction of the second member 20. As shown in Figure 3, the recess 21a has a bottom surface 24 facing the fourth surface 34 of the rod-shaped member 30 in the Y direction. In this embodiment, as shown in Figure 3, the engagement recess 21 recessing toward one side in the Z direction has a bottom surface 21b and a pair of side surfaces 21c and 21d, each of which is a portion connecting the bottom surface 21b and the opening of the engagement recess 21. In this embodiment, the recess 21a forms a part of the side surface 21c.

[0022] In this embodiment, as shown in Figure 2, a gap G1 is formed between the fourth surface 34 and the side surface 21c of the rod-shaped member 30 pressed by the pressing member 40. The gap G1 is 1.2 mm or more, preferably 1.5 mm or more, and more preferably 1.8 mm or more. For this reason, the dimension of the space S between the engaging projection 11 inserted into the engaging recess 21 and the engaging recess 21 in the direction along the Y axis (Y direction) at the insertion position of the rod-shaped member 30 is larger than the dimension of the rod-shaped member 30 in the Y direction by the dimension of the gap G1. In this embodiment, a gap G2 is also formed between the second surface 32 and the opposing surface 13 of the rod-shaped member 30 inserted into the space S. The gap G2 is preferably 0.3 mm or more, and preferably 0.5 mm or more.

[0023] In this embodiment, as shown in Figure 4, the first member 10 is provided with contact surfaces 15a and 15b that contact the second member 20 in the Z direction, and the second member 20 is provided with contact surfaces 25a and 25b that contact the contact surfaces 15a and 15b in the Z direction. The contact surfaces 15b and 25b are positioned on one side in the Y direction relative to the engaging projection 11, and the contact surfaces 15a and 25a are positioned on the other side in the Y direction relative to the engaging projection 11. In this embodiment, the inside of the chamber is the other side in the Y direction. The contact surfaces 15a, 15b, 25a, and 25b do not need to be planar. Alternatively, the first member 10 may be provided with either a contact surface 15a or a contact surface 15b, and the second member 20 may be provided with a corresponding contact surface. It is sufficient that at least a portion of the contact surfaces 15a, 15b, 25a, and 25b are provided so that the second member 20 is positioned in the Z direction relative to the first member 10. Or, other similar contact surfaces may be provided. The contact surfaces 15a, 15b, 25a, and 25b may be formed by surfaces of rubber, plastic, or the like attached to members 10 and 20.

[0024] In this embodiment, a groove 25c is provided on the contact surface 25b of the second member 20, and a sealing member 26 is housed within the groove 25c. When uncompressed, the sealing member 26 protrudes slightly from the contact surface 25b and is compressed when the contact surface 25b comes into contact with the contact surface 15b.

[0025] As shown in Figures 4 and 5, the user inserts the engaging projection 11 of the first member 10 into the engaging recess 21 of the second member 20, and inserts the rod-shaped member 30 from its end into the space S that is long in the longitudinal direction of the first member 10. At this time, the gap G1 is set. The rod-shaped member 30 has a length equivalent to the length dimensions of the first member 10 and the second member 20, or a length of 80% or more, 70% or more, of the said length dimensions. In addition, many rooms in prefabricated cargo rooms, prefabricated houses, etc., often have sides of 1 m or more, and many rooms have sides of 1.5 m or more or 2 m or more. For this reason, if the process of inserting the rod-shaped member 30 into the space S is time-consuming, the assembly of the room cannot be completed in a short time.

[0026] It is also possible to place two rod-shaped members 30 into one space S. In this case, for example, one rod-shaped member 30 is inserted from one end of space S, and the other rod-shaped member 30 is inserted from the other end of space S. Even in this case, the rod-shaped members 30 will have a length of about 50% of the length dimension of the member, or 40% or more, or 30% or more of the length dimension of the member. In other words, even in this case, if the length dimension of the member is 1.5 m, the rod-shaped members 30 will be about 45 to 75 cm long. For this reason, without the gap G1, the work of inserting the rod-shaped members 30 into space S becomes time-consuming. It should be noted that the configuration of placing one rod-shaped member 30 into one space S is preferable because it reduces the number of parts in the chamber and shortens the assembly time. This effect can be achieved even without the gap G2, but as will be described later, the gap G2 is useful.

[0027] As described above, since the rod-shaped member 30 is long, even if the rod-shaped member 30 is not bent or has no irregularities, it is difficult to insert the rod-shaped member 30 into space S without a gap G1. In this embodiment, a gap G2 is also formed between the rod-shaped member 30 inserted into space S and the first member 10. As shown in Figures 2 and 3, when inserting the rod-shaped member 30 into space S and after insertion, the second surface 32 of the rod-shaped member 30 comes into contact with the second engagement surface 22 of the first member 10, and this contact restricts the movement of the rod-shaped member 30 in the direction of the opposing surface 13. This restriction forms the gap G2. In this embodiment, as an example, as shown in Figures 2 and 3, when the contact surfaces 15a and 15b are in contact with the contact surfaces 25a and 25b in the Z direction, a step having dimensions corresponding to the gap G2 is formed between the second engagement surface 22 and the opposing surface 13. When a gap is created between the contact surface 15b and the contact surface 25b by the sealing member 26, the dimensions of the step and the gap G2 tend to become larger.

[0028] Because there is a gap G2, users, assemblers, etc., can easily move the rod-shaped member 30 within the space S after inserting it into the space S, bringing it into contact with or close to the first engagement surface 12, bottom surface 14, etc., of the engaging projection 11. If the rod-shaped member 30 is not warped or bent, users, assemblers, etc., can feel the sound and sensation of the rod-shaped member 30 contacting the first engagement surface 12, bottom surface 14, etc., during the movement within the space. Users, assemblers, etc., can also move the rod-shaped member 30 within the space S with a part of it inside, check the sound and sensation, and then insert the entire rod-shaped member 30 into the space S in that state. Even if the rod-shaped member 30 is slightly bent or has dents, the gap G2 allows the rod-shaped member 30 to move easily within the space S toward the first engagement surface 12 of the engaging projection 11, the bottom surface 14, etc., allowing the user, assembler, etc. to bring the rod-shaped member 30 closer to the first engagement surface 12, the bottom surface 14, etc.

[0029] As shown in Figure 2, the rod-shaped member 30 is pressed against the first engagement surface 12 and / or bottom surface 14 by the pressing member 40, thereby ensuring a secure connection between the first member 10 and the second member, suppressing or eliminating rattling and the resulting noise. It is preferable that the rod-shaped member 30 is pressed against the first engagement surface 12 and / or bottom surface 14 along its entire length. If the rod-shaped member 30 is warped or has dents, or if members 10 and 20 are deformed or have dents, or if the rod-shaped member 30 bends slightly due to the pressing force, it is possible that only a portion of the rod-shaped member 30 is pressed against the first engagement surface 12 and / or bottom surface 14, with the remaining portion being close to the first engagement surface 12 and / or bottom surface 14. In this case as well, it is important to position the rod-shaped member 30 on the side of the first engagement surface 12 and / or bottom surface 14.

[0030] As shown in Figure 2, in this embodiment, multiple pressing members 40 press the rod-shaped member 30 at multiple locations along its longitudinal direction toward the first engagement surface 12 and / or bottom surface 14. In this way, the pressing members 40 ultimately press the rod-shaped member 30, and the configuration in which the gap G2 allows the rod-shaped member 30 to move easily toward the first engagement surface 12, bottom surface 14, etc. of the engagement projection 11 within the space S is useful. For example, if a user, assembler, etc. performs the action of bringing the rod-shaped member 30 into contact with the first engagement surface 12, bottom surface 14, etc., and then tightens the multiple pressing members 40, the tightening work can be completed in a short time. This is because the rod-shaped member 30 is already positioned close to the first engagement surface 12, bottom surface 14, etc., before the tightening work. In addition, by feeling the sound and touch produced by the action of bringing the rod-shaped member 30 into contact with the first engagement surface 12, bottom surface 14, etc., users, assemblers, etc. can perform the assembly work with confidence, which leads to accurate assembly work and increased efficiency. Furthermore, even if the gap G1 is less than the above value, such as 0.5 mm or more but less than 1.2 mm, the effect can still be achieved.

[0031] In this embodiment, as shown in Figure 2, the rod-shaped member 30 is pressed against the first engagement surface 12 in the Z and Y directions, thereby restricting the movement of the first member 10 away from the second member 20. In some cases, the rod-shaped member 30 may be strongly pressed against the bottom surface 14, and the movement may be restricted by friction or the like. This restriction of movement contributes to suppressing rattling and the generation of noise due to rattling. In this embodiment, as shown by the arrow drawn inside the rod-shaped member 30 in Figure 3, the presence of a gap G2 allows the rod-shaped member 30 to rotate slightly when moving within the space. The presence of the gap G2 (rotation-allowing portion) may also make it easier for the rod-shaped member 30 to move in directions other than rotation when moving within the space. In this embodiment, both the effect of a firm connection between the first member 10 and the second member 20 due to the pressing of the rod-shaped member 30 against the first engagement surface 12 and the effect of the aforementioned gap G2 are achieved. In this embodiment, when pressing is performed by the pressing member 40 after the rotation, the rod-shaped member 30 tends to rotate in the opposite direction to the rotation due to contact between the third surface 33 and the bottom surface 14, etc.

[0032] As shown in Figure 9, the opposing surface 13 may be an inclined surface that is tilted with respect to the Y-axis, and may have a downward slope in the direction approaching the rod-shaped member 30. Even in this case, if the gap G2 is formed at the lower end of the downward slope, for example as shown in Figure 9, the same effect as described above can be achieved. The gap G2 may also be formed when the opposing surface 13 is tilted in a different direction.

[0033] Alternatively, as shown in Figures 10 and 11, a relief portion 32a may be provided on the second surface 32 of the rod-shaped member 30. The relief portion 32a is an inclined surface formed on the second surface 32 of the rod-shaped member 30 to create the gap G2. The relief portion 32a may be formed by a recess or the like instead of an inclined surface. The relief portion 32a can be said to be shaped to create a gap G2 so that the rod-shaped member 30 can rotate or move slightly in the direction of the arrow when the third surface 33 is pressed against the bottom surface 14. The function may be achieved even if the dimensions of the gap G2 are other than those described above.

[0034] The step between the second engagement surface 22 and the opposing surface 13, the gap G2, the inclined surface, the relief portion 32a, etc., are portions (rotation-allowing portions) that allow the rod-shaped member 30 to rotate such that the rod-side inclined surface 35 moves away from the first engagement surface 12 in the Z direction before the pressing member 40 is pressed. This rotation is, for example, rotation around an axis 30a extending along the X axis, as shown in Figure 12. Figure 12 shows the rod-shaped member 30 rotated by about 4° compared to Figure 3, but it is also possible that the rod-shaped member 30 rotates by a smaller angle.

[0035] When a configuration is adopted in which the rod-shaped member 30 is pressed against the first engagement surface 12 in the Z and Y directions by a pressing member 40 that mainly pushes the rod-shaped member 30 in the Y direction, it is preferable that one or both of the first engagement surface 12 of the first member 10 and the rod-side inclined surface 35 of the rod-shaped member 30 are provided, as shown in Figure 2, etc. For example, if the rod-shaped member 30 is provided with a rod-side inclined surface 35 and the first engagement surface 12 is provided with a corner radius as shown in Figure 8, the rod-side inclined surface 35 will contact the corner radius. It is also possible that the first engagement surface 12 is not provided with a corner radius. With this configuration, when the pressing member 40 pushes the rod-shaped member 30 in the Y direction, the contact surfaces 15a and 15b are pressed against the contact surfaces 25a and 25b.

[0036] In this embodiment, the inclination angle of the first engagement surface 12 and the rod-side inclined surface 35 with respect to the Y axis is 30° or more, but similar effects can be achieved even if it is 20° or more or 5° or more. Considering the ability to achieve both of the above effects, it is preferable that it be 10° or more, more preferably 20° or more, and even more preferably 25° or more.

[0037] Alternatively, depending on the conditions and other structures, as shown in Figure 7, an inclined surface may be provided on a part of the first engagement surface 12, and there may be no rod-side inclined surface 35, with the rod-side engagement portion being a surface along the Y-axis. The inclined surface of the first engagement surface 12 may be provided at a different position than that shown in Figure 7. Alternatively, the first engagement surface 12 may not have an inclined surface, and only the rod-side inclined surface 35 may be provided. Alternatively, instead of an inclined surface, the first engagement surface 12 may be provided with a convex curved surface (Figure 8) or a concave curved surface that facilitates inserting the rod-shaped member 30 into the recess 11a. Also, instead of the rod-side inclined surface 35, a similar convex curved surface (rod-side engagement portion) or a concave curved surface (rod-side engagement portion) may be provided. The rod-side inclined surface 35 may also consist of a part of the convex curved surface or concave curved surface provided on the rod-shaped member 30.

[0038] Alternatively, instead of providing a rod-side inclined surface 35 between the first surface 31 and the third surface 33, a groove 36 may be provided on the third surface 33 as shown in Figure 13, and a projection 17 protruding toward the rod-shaped member 30 may be provided on the engaging projection 11. In this case, a part of the projection 17 becomes the first engaging surface 12, and when the rod-shaped member 30 is pressed against the engaging projection 11 as described above, the surface in the groove 36 (rod-side engaging portion) is pressed against the first engaging surface 12 of the projection 17 in the Z and Y directions. In some cases, instead of a groove 36, a projection protruding toward the engaging projection 11 may be provided on the third surface 33, and a corresponding groove may be provided on the engaging projection 11, with the first engaging surface 12 provided within the groove. In other embodiments, the first engaging surface 12 that presses the rod-shaped member 30 toward the Z and Y directions may be formed on the engaging projection.

[0039] The user, assembler, etc., presses the rod-shaped member 30 against the first engagement surface 12 and / or bottom surface 14 by tightening the multiple pressing members 40, thereby connecting the rear panel 6 as the first panel and the roof panel 7 as the second panel.

[0040] In this embodiment, the second member 20 is fixed to the front edge, rear edge, and a pair of side edges of the roof panel 7 shown in Figure 1, and the first member 10 is fixed to the top edge of the side panel 5, the top edge of the rear panel 6, and the top edge of the front panel. This configuration connects the roof panel 7 to the side panel 5, the rear panel 6, and the front panel, forming the aforementioned panel assembly in each. In this case, the top edges of the side panel 5, the rear panel 6, and the front panel become the first edges, and the front edge, rear edge, and a pair of side edges of the roof panel 7 become the second edges. Furthermore, the aforementioned X-axis, Y-axis, and Z-axis are defined at each connection point according to the direction in which the first member 10 extends, the direction in which the engaging projection 11 protrudes, etc. Other connection points between panels may be connected in a similar manner, or other connection points may be connected by other methods such as bolts or welding. Having all connection points or 50% or more of the connection points constitute the aforementioned panel assembly is useful for completing the assembly of the room in a short time.

[0041] As shown in Figure 5, exposed portions are formed where the first member 10, the second member 20, and the end of the space S are exposed, and in Figure 5, multiple (two) ends are exposed at the corner of the room. As shown in Figure 6, a cover member 50 may be provided to cover the exposed portion, and the cover member 50 may prevent rainwater, dust, etc. from entering the exposed portion.

[0042] Users, dismantlers, etc., can release the connection between the first member 10 and the second member 20 by removing the rod-shaped member 30 from the space S. For this reason, users, dismantlers, etc., first release the pressure on the rod-shaped member 30 applied by the pressing member 40. In this state, the presence of the gap G1 allows users, dismantlers, etc., to move the rod-shaped member 30 in its longitudinal direction relative to the space S, making it easy to remove the rod-shaped member 30 from the space S. Even if the rod-shaped member 30 is warped or has dents, the gap G1 contributes to facilitating the removal. Even if the assembled chamber has been used for many years and has become stuck between the rod-shaped member 30 and the first member 10, etc., the presence of the gap G1 makes it easier to release the sticking when users, dismantlers, etc., apply force to the rod-shaped member 30 using a hammer or other means, or using the principle of leverage. The gap G2 also functions similarly during the aforementioned disconnection, and the presence of gap G2 can significantly improve the ease of disconnection compared to the case where only gap G1 is present.

[0043] In this embodiment, the first member 10 is connected to the second member 20 by the rod-shaped member 30, suppressing rattling between the first member 10 and the second member 20. Furthermore, it is preferable that the connecting parts of the panel assembly do not loosen due to wind and rain, vibrations or impact forces applied to the room. Examples of such vibrations or impact forces include vibrations or impact forces caused by earthquakes, vibrations or impact forces generated by the movement of vehicles when the room is attached to a vehicle such as a truck or railway vehicle as a cargo compartment, and vibrations or impact forces generated when the room is transported by an aircraft such as a helicopter. The rod-shaped member 30 is made of aluminum, and the first member 10 and the second member 20 are also made of aluminum. It is also possible to make only the contact parts of the first member 10 and the second member 20 with the rod-shaped member 30 out of aluminum. Although it is possible to use other metal materials instead of aluminum, aluminum is superior to other metals in terms of weight reduction and manufacturing cost reduction, and from the viewpoint of the function of this embodiment.

[0044] Furthermore, the rod-shaped member 30 has a dimension W1 in the Z direction of approximately 9 mm and a dimension W2 in the Y direction of approximately 8 mm, as shown in Fig. 4. When consideration is given to both strength and storability during disassembly, the dimension W1 in the Z direction is preferably 5 mm or more and 20 mm or less, and the dimension W2 in the Y direction is preferably 5 mm or more and 20 mm or less.

[0045] Since such a relatively strong and long rod-shaped member 30 as described above is used, loosening of the connecting portion of the panel assembly caused by wind and rain, the aforementioned vibration, or the like can be prevented or suppressed. Note that the effect can be achieved even without the aforementioned permission of rotation of the rod-shaped member 30 provided by the gap G2. Also, the effect can be achieved even when the gap G1 is equal to or smaller than the above numerical value. It is also possible to manufacture the rod-shaped member 30, the first member 10, and the second member 20 from other materials such as plastic or other metal materials having hardness and strength equivalent to that of aluminum according to conditions.

[0046] When the dimension W2 of the rod-shaped member 30 in the Y direction is 5 mm and the gap G1 is 1.2 mm or more as described above, the gap G1 is 24% or more of the dimension of the rod-shaped member 30 in the Y direction. Here, when weight reduction of the long rod-shaped member 30 is also taken into consideration, the dimension W2 in the Y direction is preferably 13 mm or less. In some cases, the dimension W1 in the Z direction may also be 13 mm or less. When the dimension W2 in the Y direction is 13 mm and the gap G1 is 1.2 mm, the gap G1 is 9% or more of the dimension W2 in the Y direction. In this way, the ratio of the gap G1 to the thickness of the elongated rod-shaped member 30 increases. In the case of a rod-shaped member 30 having a dimension W2 in the Y direction of 13 mm or less, or more preferably 11 mm or less, plastic deformation for reducing deformation or elastic deformation in a direction for reducing deformation of the rod-shaped member 30 within the space S is enabled in response to a slight deformation of the rod-shaped member 30 in the bending direction. Since the effect of the gap G1 and / or the gap G2 is added to this, the state where the rod-shaped member 30 can be smoothly inserted into the space S can be maintained over a long period of time.

[0047] Furthermore, when the rod-shaped member 30, the first member 10, and the second member 20 are made of aluminum, corrosion of each component is suppressed, which is useful for improving workability during dismantling. Also, in the present embodiment, when the rod-shaped member 30 is pressed in the Y-direction toward the engagement convex portion 11 by the pressing member 40, the entire third surface 33 of the rod-shaped member 30, the second surface 32 side of the third surface 33, and the like come into contact with the engagement convex portion 11, and the posture of the rod-shaped member 30 around the axis 30a during pressing is stabilized. For example, in the present embodiment, when the rod-side inclined surface 35 abuts against the first engagement surface 12 during the pressing due to dimensional variations of each component or the like, and the first surface 31 side of the third surface 33 does not contact the engagement convex portion 11, only the second surface 32 side of the third surface 33 contacts the engagement convex portion 11. Stabilizing the posture of the rod-shaped member 30 around the axis 30a during pressing is useful for suppressing play or the like between the first member 10 and the second member 20.

[0048] Furthermore, in the present embodiment, when the rod-shaped member 30 is inserted into the space S, the second surface 32 of the rod-shaped member 30 faces the second engagement surface 22. Therefore, in the state before the rod-shaped member 30 is pressed by the pressing member 40, the rotational position around the axis 30a of the rod-shaped member 30 is stabilized. This is useful for smoothly inserting the long rod-shaped member 30 into the space S. Furthermore, in the present embodiment, the region of the second surface 32 and the second engagement surface 22 related to the facing is substantially flat, and this configuration contributes to the smooth insertion of the rod-shaped member 30 into the space.

[0049] Furthermore, in the present embodiment, the rod-side inclined surface 35 is provided at one position on the outer peripheral surface of the rod-shaped member 30, and the first engagement surface 12 that engages with the rod-side inclined surface 35 is inclined. Therefore, if the rod-shaped member 30 is placed at another rotational position around the axis 30a, the rod-shaped member 30 cannot be inserted into the space S. That is, the rod-side inclined surface 35 also has a function of regulating the rotational position when inserting the rod-shaped member 30. In the present embodiment, the rod-side inclined surface 35, which applies a force directed into the engagement recess 21 to the engagement convex portion 11 when pressed by the pressing member 40, also has the function of regulating the rotational position, so the shape of the rod-shaped member 30 and the like is simplified, and the performance is unlikely to change over long-term use.

[0050] In addition, a member other than a screw member may be used as the pressing member 40. For example, multiple toggle mechanisms may be fixed to the second member 20, and each toggle mechanism may press a shaft against the rod-shaped member 30, thereby pressing the rod-shaped member 30 against the engaging projection 11 in the Y and Z directions.

[0051] Figures 14 to 22 show the shape of a connecting member for container assembly or a connecting member for prefabricated house assembly in which a first member 10 and a second member 20 are connected by a rod-shaped member 30. The parts shown by solid lines in Figures 14 to 21, and especially the parts shown by solid lines in Figures 18 and 19, are features of the connecting member. Figure 20 is a perspective view of the connecting member from the upper left of the front side, and Figure 21 is a perspective view of the connecting member from the upper right of the front side. The connecting member has a first member 10, a second member 20, and a rod-shaped member 30 that connects the first member 10 and the second member 20. The first member 10 is fixed to the first side, which is one side of the first panel, and the second member 20 is fixed to the second side, which is one side of the second panel. As a result, the connecting member connects the first panel and the second panel to form a panel assembly that forms the wall of the container.

[0052] As shown in Figure 18, when viewed from the right end face of the connecting member, the stopper member (bolt member) 41 is provided on the side in front of the end face of the rod-shaped member 30. In this embodiment, the rod-shaped member 30 is inserted into the space S from one end of the second member 20 (the left end in Figures 14, 20, etc.), and the stopper member 41 is screwed into the female screw hole on the other end of the second member 20 (the right end in Figures 14, 20, etc.). When the rod-shaped member 30 is inserted into the space S from the opposite side, the stopper member 41 is screwed into the female screw hole on one end of the second member 20. The tip of the rod-shaped member 30 inserted into the space S contacts the stopper member 41, causing the base end of the rod-shaped member 30 to protrude from the ends of the first member 10 and / or the second member 20 as shown in Figure 22. In this embodiment, the amount of protrusion is approximately 1 cm, and it is preferable that the amount of protrusion is 0.5 mm or more. The protruding portion is the part that the user grips when pulling out the rod-shaped member 30 during disassembly. This configuration contributes to reducing assembly and disassembly times.
