Description

The present invention relates to a sheet material fixing method using a fixed joint, in particular, to a sheet material fixing method using a fixed joint which can be suitably absorb expansion and contraction due to humidity or temperature, etc. of the plate.

  Conventionally, decorative materials such as decorative boards made by laminating and integrating decorative paper impregnated with thermosetting resin on the surface using an inorganic material with a thermosetting resin added to the base material, have a double-sided adhesive tape or adhesive. It is used to fix the base plate to the base material in the same way at intervals, so that the ends of both plates are supported by the fixed joint, and the fixed joint is fixed to the base material. I have to.

  The conventional fixed joint includes, for example, a band-shaped mounting portion fixed to a base material, vertical ribs that are raised from both ends in the width direction of the mounting portion with substantially the thickness of the plate, and laterally from the tip of each vertical rib. It is provided with a flange portion having a predetermined width that extends and supports the end portion of the plate material from the front side, and the end portion of the plate material is disposed between the flange portion and the base material.

By the way, since the plate material such as a decorative plate shrinks due to humidity, air temperature, etc., it is necessary to provide a gap between the end portion of each plate material and each vertical rib of the fixed joint so that an expansion allowance is provided under the flange portion. However, there is only a method for measuring the movable dimension of the fixed joint to determine how much clearance is provided in the conventional fixed joint.
As a result, even if the interval between the plate members is appropriately set, the gap dimension between the end portion of the plate member and the vertical rib of the fixed joint varies depending on the mounting position of the fixed joint, and the end portion of one plate member becomes the vertical rib. There is a possibility that it will be attached in a state where it is in contact or with only a small gap, and in this case, there arises a problem that when the plate material is extended, the plate material is lifted from the base material.
On the other hand, if the gap dimension becomes too large, there arises a problem that the plate material comes out of the fixed joint when contracted.

In view of the problems of the conventional fixed joints of plate materials, the present invention suitably absorbs expansion and contraction due to humidity, temperature, etc. of the plate materials by securing an appropriate expansion / contraction allowance between the fixed joints and the plate materials. and to provide a lifting or missing fixing method of the plate using a fixed joint can be prevented.

In order to achieve the above object, a method for fixing a plate material using a fixing joint according to the present invention includes a strip-shaped mounting portion fixed to a base material, a vertical rib raised from one end in the width direction of the mounting portion, and a vertical length. extending from the distal end of the rib laterally, e Bei a flange portion of a predetermined width for supporting the ends of the plate from the front side, from one widthwise end of the mounting portion, the plate member between the flange portion can enter as a space is formed, using a fixed joint plate material made by extending the projections laterally, to secure the plate member with a gap for inserting the mounting portion and the projections of the fixed joint to the base material Then, the fixing joint mounting portion and the protruding portion are inserted into the gap between the plate members, and the fixing joint is fixed to the base material .

In this case, the tip of the longitudinal ribs can Rukoto using a fixed joint plate material formed by extending the holding portion for holding the other plate material disposed at right angles to the plate.

According to the plate fixing method using the fixing joint of the present invention, the band-shaped mounting portion fixed to the base material, the vertical rib raised from one end in the width direction of the mounting portion, and the side from the tip of the vertical rib And a flange portion having a predetermined width that supports the end portion of the plate material from the front side, and a space in which the plate material can enter is formed between one end in the width direction of the attachment portion and the flange portion. As described above, the protrusion is extended to the side, and further, if necessary, fixed using a plate joint that extends a holding portion for holding another plate disposed at a right angle to the plate. Fix the plate to the base material with a gap to insert the fitting attachment and protrusion, and then insert the fixed joint attachment and protrusion to the plate to fix the fixed joint to the base. From the plate that is fixed to the base material with a gap. It can be positioned without being biased between them, and an appropriate expansion / contraction allowance can be ensured between the plate and the plate, which absorbs expansion / contraction due to humidity, temperature, etc., and the plate is lifted and fixed. The disconnection from the joint can be prevented.

Hereinafter, the embodiments of the plate fixing method using a fixed joint of the present invention will be described with reference to the drawings.

In FIGS. 1-2, showing a reference example of the plate fixing method using a fixed joint and the fixing joint plate.
The plate joint 1 is a so-called hat-type joiner, which is a belt-like attachment portion 11 fixed to the base material 2 on the ceiling surface, and the thickness of the plate 3 from both ends of the attachment portion 11 in the width direction. 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. 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.
Then, as shown in FIG. 1 (c), the attachment portion 11 and the protrusion 14 of the fixed joint 1 are inserted into the center of the gap of the plate member 3, and as shown in FIG. Fix to the base material 2.
A cosmetic caulking material S can be disposed on the front side of the attachment portion 11.

By the way, when the attachment portion 11 and the protrusion 14 of the fixed joint 1 are inserted into the gap between the plate members 3, the protrusion 14 temporarily serves as a spacer, so that the fixed joint 1 approaches one plate member 3. As shown in the figure, the spaces 15a are formed substantially equally on the left and right sides.
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 of this reference example and the plate member fixing method using this fixing joint are the band-shaped attachment portion 11 fixed to the base material 2 and the vertical portions raised from both ends of the attachment portion 11 in the width direction. The rib 12 includes a flange 13 having a predetermined width that extends laterally from the front end of each vertical rib 12 and supports the end of the plate member 3 from the front side. In order to form a space 15 into which the plate member 3 can enter, the plate member fixed joint 1 with the protrusions 14 extending laterally is used, and the attachment portion 11 and the protrusion 14 of the fixed joint 1 are The two plate members 3 are adhered and fixed to the base material 2 with a gap that 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 material 2 to fix the fixed joint 1 to the base. Since it is fixed to the material 2, the fixed joint 1 is provided by the protrusion 14. In addition to being able to position without bias between the two sheets 3 adhered and fixed to the base material 2 with a gap, an appropriate expansion / contraction allowance can be secured between the sheets 3 and this Thus, the expansion and contraction of the plate 3 due to humidity, temperature, etc. can be suitably absorbed, and the plate 3 can be prevented from being lifted or detached from the fixed joint.

Next, FIG. 3 shows an embodiment of a plate material fixing method using the fixing joint of the present invention.
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. A vertical rib 62, a flange 63 having a predetermined width that extends from the front end of the vertical rib 62 and supports the end of the plate member 3 from the front side, and provided at the front end of the vertical rib 62, are orthogonal to the plate member 3. And a U-shaped support portion 66 that supports the other plate material 3, and a protrusion 65 is formed so that a space 65 into which the plate material 3 can enter is formed between one end in the width direction of the attachment portion 61 and the flange portion 63. 64 is extended to the side.
The holding portion 66 holds the other plate material 3 provided on the wall surface with respect to the plate material 3 provided on the ceiling surface. When the other plate material 3 is not provided on the wall surface, the holding portion 66 is provided. Can be omitted.

In this case, the fixed joint 6 is made of a long pultrusion molding material or extrusion molding material of a metal such as aluminum having the same cross section in the longitudinal direction or a synthetic resin, and a protruding portion 64 extending to the side of the mounting portion 61. 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 64 is not particularly limited, but its 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 64 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 affixed on 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 64 has thickness. Also, it can enter the space 65 formed between the protrusion 64 and the flange portion 63.

Then, using this fixed joint 6, the ceiling-side plate material 3 is attached to the base material 2 so that there is a gap for inserting the mounting portion 61 and the protrusion 64 of the fixed joint 6 between the wall surface 7, and then The mounting portion 61 and the protrusion 64 of the fixed joint 6 are inserted into the gap between the wall surface 7 and the plate material 3, and the fixed joint 6 is fixed to the base material 2.
Specifically, as shown in FIG. 3B, the gap between the wall 7 and the mounting portion 61 of the fixed joint 6 and the width of the projection 64 is substantially the same, for example, a large gap in the range of about 1 to 3 mm. The ceiling-side plate material 3 is attached to the base material 2, and then the fixed joint 6 is inserted into the gap between the plate material 3 and the wall surface 7, and the support portion 66 is screwed to the wall surface 7 to fix the fixed joint. 6 is fixed to the base material 2.
Then, as shown in FIG. 2, the plate member 3 on the wall surface side is inserted into the U-shaped support portion 66, and the plate member 3 is fixed to the base material 2 on the wall surface.
In this case, the plate material 3 is attached to the base material 2 via the double-sided pressure-sensitive adhesive tape 4 and the adhesive 5 on both the ceiling side and the wall surface side.

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 method using the fixing joint according to the present embodiment includes a strip-shaped attachment portion 61 fixed to the base material 2, the vertical rib 62 raised from one end in the width direction of the attachment portion 61, and the vertical rib. And a flange portion 63 having a predetermined width that extends from the front end of 62 to the side and supports the end portion of the plate member 3 from the front side, and the plate member 3 is between the flange portion 63 from one end in the width direction of the mounting portion 61. The projecting portion is extended to the side so that the space 65 that can be entered is formed, and further, a holding portion 66 that holds another plate member 3 arranged at right angles to the plate member 3 is extended. The fixed joint 6 is used to attach and fix the plate member 3 to the base material 2 with a gap for inserting the attachment portion 61 and the protrusion 64 of the fixed joint 6, and then the attachment portion 61 and the protrusion 64 of the fixed joint 6. Is inserted into the gap of the plate 3 and the fixing joint 6 is fixed to the base material 2 In addition, the fixed joint 6 can be positioned by the protrusion 64 without being biased to the gap of the plate 3 attached and fixed to the base material 2 with a gap, and an appropriate expansion / contraction allowance is secured with the plate 3 Accordingly, 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 6.
