The protrusions 14 are extended laterally from both ends so that a space 15 into which the plate 3 can enter is formed between the flanges 13 and both ends.

In this case, the fixed joint 1 is made of a long pultrusion molding material or an extrusion molding material of a metal such as aluminum having the same cross section in the longitudinal direction or a synthetic resin, and a protrusion 14 extending to the side of the mounting portion 11. The width w is set to a width that can absorb expansion and contraction of the plate 3 due to humidity, temperature, and the like.
More specifically, the protrusion 14 is not particularly limited, but the width w is about 1 to 3 mm of 1/3 to 1/5 of the flange portion 13, and the thickness t is about 0.5 to 1 mm. And formed as ridges continuous in the longitudinal direction.

In addition, the thickness t of the protrusion 14 is formed to be slightly thinner than the thickness of the double-sided pressure-sensitive adhesive tape 4 used for sticking the plate material 3 to the base material 2.
Thereby, the board | plate material 3 stuck to the base material 2 via the double-sided adhesive tape 4 and the adhesive agent 5 is in the state which floated about 1 mm from the base material 2, and the protrusion 14 has thickness. Also, it can enter the space 15 formed between the protrusion 14 and the flange portion 13.

Then, using this fixed joint 1, the two plate members 3 are adhered to the base material 2 with a gap where the mounting portion 11 and the protrusion 14 of the fixed joint 1 can be inserted, and then the mounting portion 11 of the fixed joint 1. And the protrusion 14 is inserted into the gap between the plate members 3, and the attachment portion 11 of the fixed joint 1 is fixed to the base material 2.
Specifically, as shown in FIG. 1 (b), one plate material 3 is first adhered to the base material 2 by the double-sided pressure-sensitive adhesive tape 4 and the adhesive 5, and then the attachment portion 11 of the fixed joint 1 and The other plate material 3 is adhered to the base material 2 with a gap that is substantially the same as the width of the protrusion 14, for example, in the range of about 1 to 3 mm.

Further, when the gap is narrow, the fixed joint 1 cannot be inserted, so that it is possible to prevent a construction failure.
After fixing the fixed joint 1, the space 15a formed between the end of the plate 3 and the vertical rib 12 functions as a space that absorbs the elongation of the plate 3, and the space 15a (15) has an end of the plate 3 in the space 15a (15). Since the part can enter, the expansion and contraction due to the humidity and temperature of the plate 3 can be suitably absorbed, and the plate 3 can be prevented from being lifted.
Moreover, since the fixed joint 1 is inserted in the approximate center between the board | plate materials 3, even when the board | plate material 3 shrink | contracts, it can prevent detachment | leave from the fixed joint 1. FIG.
Note that the illustrated example shows the case where the plate member 3 is fixed to the ceiling surface, but the present invention can also be applied to the case where the plate member 3 is fixed to the wall surface, for example.

  Thus, the plate member fixing joint and the plate member fixing method using the fixing joint of the first embodiment are started up from the band-shaped attachment portion 11 fixed to the base material 2 and the width direction ends of the attachment portion 11. Each of the vertical ribs 12 and a flange 13 having a predetermined width extending from the front end of each vertical rib 12 to support the end of the plate member 3 from the front side. In order to form a space 15 into which the plate material 3 can enter between the portion 13 and the plate 13, the fixed joint 1 of the plate material in which the protrusions 14 are extended laterally is used, and the mounting portion 11 and the protrusion of the fixed joint 1 are used. The two plate members 3 are adhered and fixed to the base material 2 with a gap into which the plate 14 can be inserted, and then the mounting portion 11 and the protrusion 14 of the fixed joint 1 are inserted into the gap of the plate member 2 to fix the fixed joint 1. Is fixed to the base material 2, and is fixed by the protrusion 14. 1 can be positioned without being biased between the two plate members 3 adhered and fixed to the base material 2 with a gap, and an appropriate expansion / contraction allowance can be secured between the plate members 3. Thereby, the expansion and contraction due to the humidity and temperature of the plate member 3 can be suitably absorbed, and the plate member 3 can be prevented from being lifted or detached from the fixed joint.

Next, FIG. 3 shows a second embodiment of the fixing joint for the plate material of the present invention and the fixing method for the plate material using the fixed joint.
This plate material fixing joint 6 is for a peripheral edge, and is formed with a strip-shaped mounting portion 61 fixed to the base material 2 on the ceiling surface, and a thickness of the plate material 3 from one end in the width direction of the mounting portion 61.

In this case, when the fixed joint 6 is inserted into the gap between the wall surface 7 and the plate material 3, the protrusion 64 temporarily serves as a spacer, so that the fixed joint 6 is too close to the plate material 3 on the ceiling side. Inserted without.
Further, when the gap is narrow, the fixed joint 6 cannot be inserted, so that it can be determined as a construction failure.
After fixing the fixed joint 6, the space 65 a formed between the end portion of the plate material and the vertical rib 62 functions as a space that absorbs the elongation of the plate material 3, and thereby, the expansion and contraction of the plate material 3 due to humidity, temperature, etc. Absorbing suitably, the board | plate material 3 can be prevented from floating.
Further, since the fixed joint 6 is properly positioned and inserted by the protrusion 64, it is possible to prevent the fixed joint 6 from coming off from the fixed joint 6 even when the plate member 3 is contracted.

  Thus, the plate member fixing joint and the plate member fixing method using this fixing joint of the second embodiment are raised from the belt-like mounting portion 61 fixed to the base material 2 and one end in the width direction of the mounting portion 61. And a flange portion 63 having a predetermined width that extends from the front end of the vertical rib 62 to the side and supports the end portion of the plate member 3 from the front side. A protrusion is extended laterally so that a space 65 into which the plate 3 can enter is formed between the plate 63 and a holding member for holding another plate 3 arranged at right angles to the plate 3. The plate member 3 is attached to and fixed to the base material 2 with a gap for inserting the mounting portion 61 and the protrusion 64 of the fixed joint 6, and then the fixed joint 6. The mounting portion 61 and the protrusion 64 are inserted into the gap between the plate members 3 to fix the fixed joint. Is fixed to the base material 2, so that the fixed joint 6 can be positioned by the protrusion 64 without being biased to the gap of the plate material 3 that is adhered and fixed to the base material 2 with a gap therebetween. An appropriate expansion / contraction allowance can be ensured during this period, whereby the expansion / contraction due to the humidity, temperature, etc. of the plate material 3 can be suitably absorbed, and the plate material 3 can be prevented from being lifted or detached from the fixed joint 6.
