DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a ceiling panel by attaching a ceiling panel to a ceiling base surface.

[0002]

2. Description of the Related Art In bonding a ceiling plate to a ceiling base surface such as a lower surface of a slab by bonding, it is necessary to hold the ceiling plate by some holding means until the adhesive is cured.

[0003] For example, in addition to the permanent bonding adhesive, an adhesive that cures quickly is applied to the back surface of the ceiling plate, and temporarily fastened with an adhesive that cures quickly until the final adhesive is cured. However, in this case as well, it is necessary to hold the ceiling plate by some holding means until the fast curing adhesive is cured. In addition, when an instant adhesive is used as an adhesive that cures quickly, it takes a little time to slide the ceiling plate and perform the work of positioning and joining the adjacent ceiling plate by fitting the real part and the fitting recess. In such a case, the instant adhesive is hardened, so that the ceiling plate cannot be slid and cannot be put to practical use at all.

[0004] Therefore, the present inventor, in the process of reaching the present invention,
Adhere a double-sided adhesive tape to the ceiling base surface, attach a ceiling plate with adhesive applied to the back (upper surface), and temporarily fix it with double-sided adhesive tape until the adhesive is cured and fully fixed Was. However, the ceiling plate is placed on the lower surface side of the double-sided adhesive tape, and the ceiling plate is slid in the lateral direction to perform positioning work, or work to join the adjacent ceiling plate by fitting the real part and the fitting recess. Even, the ceiling plate is stuck to the adhesive layer on the lower surface of the double-sided adhesive tape,
It turned out that there was a problem that it was not possible to slide in the horizontal direction, and positioning work and joining work could not be performed.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and ensures that the ceiling plate is temporarily fixed until the adhesive cures and the ceiling plate is completely fixed. It is an object of the present invention to provide a method of constructing a ceiling plate that can be fixed and that can be easily positioned and joined by sliding the ceiling plate in a horizontal direction when the ceiling plate is constructed.

[0006]

When the adjacent ceiling plates 8 are joined to each other by fitting the real portion 9 and the fitting concave portion 10 at the side end portions, the ceiling plate 8 smoothly hits the net 4 and does not adhere to the adhesive layer 2. After the real part 9 and the fitting recess 10 are fitted, the ceiling plate 8 is strongly pressed against the double-sided adhesive tape 5 so that the net 4 part sinks and the adhesive is The ceiling plate 8 is stuck to the layer 2 and temporarily supported, and the ceiling plate 8 can be temporarily held securely until the adhesive 7 is hardened and permanently fixed.

It is preferable that two double-sided adhesive tapes 5 are attached to the ceiling base surface 6 in the longitudinal direction of the ceiling plate 8 at intervals smaller than the width of the ceiling plate 8.

By adopting such a method, the net 4 laminated on the adhesive layer 2 on the double-sided adhesive tape 5 stuck on the upper surface of the ceiling plate 8 is coated with the adhesive 7 on the lower surface of the ceiling base surface 6. When the ceiling plate 8 is slid laterally and the adjacent ceiling plates 8 are joined to each other by fitting the real part 9 and the fitting recess 10 at the side ends, Can be smoothly slid in the lateral direction in a state where the net 4 has hit and does not adhere to the adhesive layer 2, and after the real part 9 and the fitting concave part 10 have been fitted, the double-sided adhesive tape 5 By strongly pressing the ceiling plate 8 against the ceiling base surface 6 through the base, the net 4 sinks and the ceiling base surface 6 is attached to the pressure-sensitive adhesive layer 2 and temporarily supported, and the adhesive 7 hardens when the adhesive 7 is hardened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments shown in the accompanying drawings.

FIG. 1 is a perspective view of a double-sided adhesive tape 5 used in the present invention. That is, pressure-sensitive adhesive layers 2 and 3 are provided on both surfaces of a band 1 made of a synthetic resin foam having flexibility, and a net 4 is laminated on the pressure-sensitive adhesive layer 2 on one surface. Here, the net 4 is formed of a nonwoven fabric of polypropylene.

A ceiling plate 8 such as a rock wool board is stuck to a ceiling base surface 6 such as a slab using the double-sided adhesive tape 5 having the above-described structure, and is constructed as follows.

First, as shown in FIG. 3, ink is applied to the ceiling base surface 6 and a black line A, which is a reference line in the longitudinal direction of the ceiling plate 8 and is parallel to the longitudinal direction of the ceiling plate 8, and A black line B parallel to the short side of the ceiling plate 8 serving as a reference line on the short side;
Draw an auxiliary black line C parallel to.

Next, as shown in FIG. 4, two double-sided pressure-sensitive adhesive tapes 5 are attached to the ceiling base surface 6 in parallel with the black line A, with the surface on which the net 4 is laminated facing downward. .

Next, as shown in FIG. 5, a ceiling plate 8 in which an adhesive 7 such as a one-component urethane adhesive is partially applied in a spot shape or a line shape on the back surface (upper surface) is attached to both sides. In this state, the black line A is aligned with one side of the ceiling plate 8 in the longitudinal direction and one short side is aligned with the black line B, as shown in FIG. In this case, as shown in FIG. 7, the ceiling plate 8 only hits the net 4 and does not hit the exposed portion of the adhesive layer 2, so that the ceiling plate 8 can be slid smoothly to the side to facilitate alignment. be able to. Here, if the net 4 is formed of a nonwoven fabric as in the embodiment, the adhesive slightly exudes to the lower surface of the net 4 made of the nonwoven fabric, and the net 4
The lower surface of the net 4 has a weak adhesive property, so that it does not hinder the sliding of the ceiling plate 8 in a state where the ceiling plate 8 is in contact with the lower surface of the net 4. Hold the net 4 when moving the slide
The ceiling plate 8 can be slid in a state in which the ceiling plate 8 does not drop downward by a certain amount so that the work can be easily performed. Of course, the net 4 may be formed of a material other than the nonwoven fabric, and the lower surface of the net 4 may not be made to have weak adhesiveness. Here, when the width of the short side of the ceiling plate 8 is 303 mm, the distance between the two double-sided adhesive tapes 5 is set to about 250 mm, and the distance between the two ends of the ceiling plate 8 in the width direction is set inward. 23
The ceiling plate 8 is temporarily bonded and temporarily held by the double-sided adhesive tape 5 at a position shifted inward by about 24 mm.
In other words, if the double-sided adhesive tape 5 is positioned deviated to the outside in the width direction, the double-sided adhesive tape 5 may hinder the fitting operation between the real part 9 and the fitting concave part 10 in the next row,
Further, if it is positioned too inward, the widthwise end of the ceiling plate 8 is likely to hang down, and the effect of temporary holding may not be sufficiently exhibited. When the adhesive 7 is partially applied to the back surface of the ceiling plate 8 in a spot shape or a line shape, the double-sided adhesive tape 5 is applied when the ceiling plate 8 is constructed.
Is applied so as to be in a position avoiding the above. The width of the double-sided pressure-sensitive adhesive tape 5 is, for example, 18 mm, but is not limited thereto.

When the positioning of the first ceiling plate 8 in the first row is completed as described above, the first ceiling plate 8 is strongly pressed upward. In this manner, the ceiling plate 8 is
By pressing strongly on the net 4, as shown in FIG.
The ceiling plate 8 is stuck to the pressure-sensitive adhesive layer 2 and temporarily supported, and the first ceiling plate 8 is securely held until the adhesive 7 is hardened and permanently fixed.

Next, as shown in FIG. 9, the second ceiling plate 8 is
The first ceiling plate 8 and the second ceiling plate 8 are slid in the longitudinal direction of the ceiling plate 8 in a state where one side in the longitudinal direction is aligned with the black line A, and the first ceiling plate 8 and the second ceiling plate 8 Are joined by fitting. Here, a real part 9 is formed on one side at the side end of the adjacent ceiling plate 8, and a fitting recess 10 is formed on the other, and the real part 9 and the fitting recess 10 are connected as shown in FIG. They are fitted and joined. In this state, when the second ceiling body 8 is strongly pressed against the double-sided adhesive tape 5, the net 4 sinks and the ceiling plate 8 is attached to the adhesive layer 2 and temporarily supported, and the adhesive 7 is cured. Until the book is fixed
The second ceiling plate 8 is securely held temporarily. Similarly, the ceiling boards 8 are successively constructed, and the first row is constructed as shown in FIG.

Next, as shown in FIG. 12, two double-sided pressure-sensitive adhesive tapes 5 in the second row are placed in parallel with the ceiling plate 8 in the first row, with the surface on which the nets 4 are laminated, facing down. 3 is attached to the ceiling base surface 6.

Next, the first ceiling plate 8 in the second row is applied to the net 4 side of the two double-sided adhesive tapes 5 in the second row, and the long side of the first row in the second row is set. And the long side of the ceiling plate 8 in the first row are joined by fitting the real part 9 and the fitting recess 10, and then the first ceiling board 8 in the second row is slid in the longitudinal direction. As shown in FIG. 13, one short side is positioned in accordance with the auxiliary black line C, and in this state, the first ceiling plate 8 in the second row is strongly pressed against the double-sided adhesive tape 5 so that the net 4 sinks. Until the ceiling plate 8 is attached to the adhesive layer 2 and temporarily supported, and the adhesive 7 is hardened and permanently fixed.
The first ceiling plate 8 in the second row is temporarily held securely.

Thereafter, the second ceiling plate 8 in the second row is applied to the net 4 side of the two double-sided adhesive tapes 5 in the second row, and the long side of the first sheet in the second row is The long side of the ceiling plate 8 in the first row is joined by fitting the real part 9 and the fitting recess 10, and then the second ceiling board 8 in the second row is slid in the longitudinal direction. One short side is joined to the short side of the second ceiling plate 8 in the second row by fitting the real part 9 and the fitting concave part 10 (FIG. 14). In this state, by strongly pressing the second ceiling plate 8 of the second row against the double-sided adhesive tape 5, the net 4 sinks and the ceiling plate 8 is attached to the adhesive layer 2 and temporarily supported, and is adhered. Until the agent 7 is hardened and permanently fixed, the second ceiling plate 8 in the second row is securely held temporarily. Similarly, the ceiling boards 8 are successively constructed, and the second row is constructed as shown in FIG.

The ceiling boards 8 in the third and subsequent rows are similarly constructed, and all ceiling boards 8 are constructed as shown in FIG.

By performing the construction as described above, the ceiling plate 8 can be temporarily held on the ceiling base surface 6 by the double-sided adhesive tape 5 until the adhesive 7 is hardened.
Here, when the adhesive 7 is applied to the back surface of the ceiling plate 8, the adhesive 7 is partially applied in a spot shape or a line shape so as to be thicker than the thickness of the double-sided adhesive tape 5. The ceiling base surface 6 and the ceiling plate 8 can be securely bonded to each other without being disturbed by the double-sided pressure-sensitive adhesive tape 5 in the portion where there is not.

Next, another embodiment of the present invention will be described. That is, in the above-described embodiment, the pressure-sensitive adhesive layer 3 on the double-sided pressure-sensitive adhesive tape 5 with the surface on which the net 4 is laminated faces downward.
Was applied to the ceiling base surface 6 and the adhesive 7 was partially applied to the ceiling plate 8, but in the present embodiment, the surface on which the net 4 of the double-sided adhesive tape 5 is laminated is directed upward. The lower adhesive layer 3 on the upper surface of the ceiling plate 8,
On the other hand, the adhesive 7 is partially applied to the ceiling base surface 6, and then the net 4 laminated on the adhesive layer 2 on the double-sided adhesive tape 5 attached to the upper surface of the ceiling plate 8 is adhered to the lower surface. Ceiling plate 8 with the agent 7 partially applied to the ceiling base surface 6
Sideways, the adjacent ceiling plates 8 are joined to each other by fitting the real part 9 and the fitting concave part 10 at the side ends, and in this state, the ceiling plate 8 is attached via the double-sided adhesive tape 5 to the ceiling base surface. 6, the pressure-sensitive adhesive layer 2 is stuck on the ceiling base surface 6 to temporarily support the ceiling plate 8, and the adhesive 7 is cured in this temporarily supported state, and the ceiling plate 8 is 8
Is bonded to the ceiling base surface 6. As described above, the point that the double-sided adhesive tape 5 is previously applied to the ceiling plate 8 side and the adhesive 7 is preliminarily applied to the ceiling base surface 6 side is different from the above-described embodiment, and the other points are the same as those of the above-described embodiment. Since the configuration is the same as that of the embodiment, a duplicate description will be omitted.

In this embodiment, the lower pressure-sensitive adhesive layer 3 is attached to the upper surface of the ceiling plate 8 with the surface of the double-sided pressure-sensitive adhesive tape 5 on which the net 4 is laminated facing up, and then the upper surface of the ceiling plate 8 As shown in FIG. 17, the net 4 laminated on the pressure-sensitive adhesive layer 2 on the double-sided pressure-sensitive adhesive tape 5 applied to the ceiling base surface 6 partially coated with the adhesive 7 on the lower surface as shown in FIG. When the ceiling plate 8 is slid horizontally to join the adjacent ceiling plates 8 by fitting the real part 9 and the fitting concave part 10 at the side ends, the net 4 hits the ceiling base surface 6 and the adhesive layer is formed. 2
18 can be smoothly slid in the lateral direction without being attached to the surface, and after the real part 9 and the fitting concave part 10 have been fitted, as shown in FIG. By strongly pressing the ceiling plate 8 against the ceiling base surface 6 through the base, the net 4 sinks and the ceiling base surface 6 is attached to the pressure-sensitive adhesive layer 2 and temporarily supported, and the adhesive 7 hardens when the adhesive 7 is hardened. Until fixed, the ceiling plate 8 can be securely held temporarily. It should be noted that the order in which a large number of ceiling boards 8 are applied to the ceiling base surface 6 is the same as that shown in FIGS. 9 to 16, and the description of this point is omitted because it is redundant. I do.

In this embodiment, the ceiling base surface 6
