In the case of the wall panel joint structure of this example, the pair of wall panels 10 can be joined by the following procedure. First, in this example, the joint member 24 is previously fixed to the reinforcing frame 18 of one wall panel (the left wall panel in FIG. 2) 10 by the fixing clip 26. The fixing of the joint member 24 by the fixing clip 26 can be easily performed as follows. That is, as shown in FIG. 3, the joint member 24 is applied to the back surface of one of the reinforcing frames 18, the fixing clip 26 is inserted from the side of the retaining engagement portion 36 into the through hole 32 of the fixing portion 30, and The reinforcing frame 18 is inserted into a portion (slit-shaped opening 20) between the pair of bent claws 22.

Position and constrain. In this example, the other parts have the same configuration as the above-mentioned example, and therefore only the reference numerals are shown and detailed description is omitted.

Also in the joint structure of the wall panels of this example, the pair of wall panels 10 can be joined by the same procedure as in the above embodiment. That is, as shown in FIG. 6, first, the joint member 5 for the corner is attached to the one wall panel 10.
8 is attached in advance by the fixing clip 26,
Then, as shown in FIG. 11A, the pair of elastic hooking claws 48 of the joint member 58 is reinforced on the other wall panel 10 by raising the other wall panel 10 from the indoor side to the outdoor side. It is elastically inserted into the slit-shaped opening 20 of the frame 18. Then, by bending the pair of elastic hooking claws 48 and hooking them on the tips of the claws 22, the pair of wall panels 10 can be brought into a joined state at the corners.

As described above, in this example, the joint member 2
An extension portion 54 and a pair of elastic hooking claws 48 projecting from the body portion 28 are provided on the plate-like body portions 28 of the reference numerals 4, 58, and the extension portion 54 is brought into contact with the back surface of the other reinforcing frame 18 in a pair. Of the elastic hooking claws 48 are inserted into the slit-shaped openings 20 of the other reinforcing frame 18 so that the elastic hooking claws 48 are located inside the bent-up claws 22 on the left and right edges of the slit-shaped opening 20 and from each other. The pair of reinforcing frames 18, that is, the pair of wall panels 10 are joined together by elastically hooking them in the opposite direction to prevent them from coming off.

In this example, when the pair of elastic hooking claws 48 elastically hook on the pair of bent claws 22 on the left and right edges of the slit-shaped opening 20 in the reinforcing frame 18, the elastic hooking claws 48 contact each elastic hooking claw 48. On the other hand, deformation forces in opposite directions act on each other,
The reaction forces act in a direction of canceling each other, and the transmission of the deformation force of the elastic hooking claw 48 to the plate-shaped main body portion 28 of the joint members 24 and 58 is suppressed. Therefore, the plate-shaped main body portion 28 is not largely flexed and deformed at that time, and therefore, the elastic insertion work of the pair of elastic hooking claws 48 into the slit-shaped opening 20 and the pair of reinforcing frames by the joint members 24 and 58 are therefore performed. It is easy to carry out the joining work of the 18 pieces, and it is possible to easily join the pair of wall panels 10.

Further, in this example, the joint member 2
4, 58 are provided with a pair of elastic hooking claws 48 as described above,

In addition, the joint member 24, 58 is formed with an extension portion 54, and the extension portion 54 is in contact with the back surface of the other reinforcing frame 18 to restrain it, so that the wall panel 10 is restrained. Is more stably performed, and therefore there is no fear that the panel will be disconnected even if a clockwise force is applied to the wall panel 10 on the left side in FIG. 5 from the inside.

In the present example, since the slit-shaped opening 20 in the reinforcing frame 18 is continuously formed over the entire height of the wall panel 10, the joint members 24 and 58 are used at arbitrary positions in the vertical direction. The pair of wall panels 10 can be joined together.

Further, since the joint members 24 and 58 are formed with a positioning portion 56 for contacting the inner surface with the side surface of one of the reinforcing frames 18, the joint is based on the positioning action of the positioning portion 56. The assembly positions of the members 24, 58 can be easily and accurately defined, and therefore, the joint members 24, 58 can be easily attached to the reinforcing frame 18, and the connecting work between the reinforcing frames 18 can be easily performed.

Further, in this embodiment, since the joint members 24 and 58 are fixed to the reinforcing frame 18 by the fixing clip 26, the joint members 24 and 58 can be simply and without using a tool.
Can be fixed work against.

Further, in the joint member 58 for corners, a positioning portion 60 which is cylindrical with the body 28 is provided on the inner surface side of the plate-shaped body 28, and the positioning portion 60 is formed into a pair of right angles. Since the position control of each wall panel 10 and the mounting position of the joint member 58 to the wall panel 10 are controlled by contacting each end face of the wall panel 10 of the above, the pair of wall panels at the corner portion is controlled. The assembling work of 10 can be easily performed, and the joint strength of the wall panel 10 can be increased.

In addition, since the joint members 24 and 58 are made of resin, the cost of parts required for the joint members 24 and 58 can be reduced.

7 to 9 show still another embodiment of the present invention. This example is an example in which a pair of wall panels 10 are joined by a joint member in the flat portion, and reference numeral 64 in the drawing is the joint member.

In this embodiment, the second pair of elastic hooking claws 66 are integrally formed in the fixing portion 30 of the plate-shaped main body 28 of the joint member 64, and the pair of elastic hooking claws 66 are used to fix the above-mentioned fixing. Clip 26
The fixing means instead of is constructed.

Also in this example, one wall panel 10 is previously prepared.
The joint member 64 is fixed to the reinforcing frame 18 of No. 1 and the one wall panel (the right wall panel in the drawing) 10 is raised after that as shown in FIG. 9 (A). The pair of elastic hooking claws 48 are hooked to the bent claws 22 of the reinforcing frame 18 to join the pair of wall panels 10.

When fixing the joint member 64 to the one wall panel 10 in advance, in this embodiment, the second pair of elastic hooking claws 66 are simply elastically inserted into the slit-shaped opening 20 of the reinforcing frame 18. The joint member 64 can be easily fixed.

According to this embodiment, the fixing clip 26, which is a separate body from the joint member 64, is not required as in the above-described embodiment, and the pair of wall panels 10 is joined by only a single type of component. Therefore, there is an advantage that the number of required parts is small and therefore the cost can be reduced.

10 and 11 show still another embodiment of the present invention, in which 68 is a corner joint member. In the present example, the joint member 68 is integrally formed with a second pair of elastic hooking claws 66 as fixing means in the fixing portion 30, and these second pair of elastic hooking claws 66 are formed by bending the reinforcing frame 18. The joint member 68 is fixed to one of the reinforcing frames 18 by being hooked on the raising claw 22.

Also in this embodiment, as in the embodiment of FIGS. 7, 8 and 9, when the joint member 68 is attached to the reinforcing frame 18 of the one wall panel 10 in advance, the second pair of elastic hooking claws 66 are attached.
