DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of surface decorative members arranged side by side on a surface of a synthetic resin foam layer with a gap therebetween, and integrally bonded to each other. The present invention relates to a method for removing a surface decorative member from a filled decorative panel.

[0002]

2. Description of the Related Art Conventionally, in a decorative panel of the above-mentioned type, for example, when a defect is found on a surface of a part of a decorative member, or when a fixed posture is not correct and joints are not aligned, there are some cases. As an example of a method of removing the surface decorative member, first, a joint material is removed from the periphery of the surface decorative member to be removed using a screwdriver or the like, and a screwdriver is inserted into a gap between adjacent surface decorative members. For example, a method has been adopted in which the decorative surface member is peeled off from the synthetic resin foam layer by inserting a screwdriver or the like and using the leverage (leverage) action to cause the driver.

[0003]

However, the above-mentioned conventional method requires technical skill and at the same time tends to cause irrational results. That is, in the above conventional method,
Depending on how the driver is used in the process of raising the surface decoration member, the driver may hit the adjacent surface decoration member and damage it, and it may be necessary to newly remove the surface decoration member that was originally healthy and did not have to be peeled off Even if the property is relatively high or the adjacent surface decorative member is not damaged, the surface decorative member to be removed will not be raised as it is, it will crack and part will not peel off, and the raising operation must be repeated many times, It was easy and time-consuming. Furthermore, when the surface decorative member is raised, only the surface decorative member is not peeled off, but a part of the synthetic resin foam layer adhered to the back surface of the member is peeled off with a large thickness. Unnecessary results were liable to occur, such as a need for repair work to fill newly created cavities in the synthetic resin foam layer before bonding. The present invention is technically easier than a conventional method of mechanically inducing a surface decorative member with a driver or the like as described above, and furthermore, a surrounding surface decorative member or a synthetic resin foam layer on the back surface of the surface decorative member. It is an object of the present invention to provide a method of removing a surface decorative member, which hardly causes a serious defect to the surface.

[0004]

In order to achieve the above-mentioned object, a method of the present invention comprises a plurality of surface decorative members arranged on a surface of a synthetic resin foam layer with a gap therebetween and integrally bonded to each other so as to be adjacent to each other. From the decorative panel in which the gap between the mating surface decorative members is filled with the joint material, the following three steps are performed: (a) a first step of removing the joint material from around the surface decorative member; (b) A second step of allowing a wire to enter a boundary between the surface decorative member and the synthetic resin foam layer from around the surface decorative member from which the joint material has been removed; and (c) applying tension to the wire. A third step of moving the wire substantially along an adhesive surface of the surface decorative member to the synthetic resin foam is sequentially performed to remove the specific surface decorative member.

[0005]

By performing the above three steps in order, first, in the first step, the joint material existing between the surface decorative member to be removed and the surrounding surface decorative member is removed, so that the surface decorative member is removed. The boundary between the synthetic resin foam layers can be exposed, and in the second step, the wire is made to enter and contact one of the exposed boundaries,
The position of the wire can be set, and in the last third step, the positioned wire is moved along the bonding surface of the surface decorative member with the synthetic resin foam while applying tension to the wire, The wire can be passed over the entire back surface of the target surface decorative member.

[0006]

As a result of each of the above steps, it is technically easy to simply move the wire along the bonding surface of the surface decorative member, and the surrounding surface decorative member and the synthetic resin foam on the back surface of the surface decorative member. A gap can be formed between the surface decorative member and the synthetic resin foam layer on the back surface through a static operation that does not impact the layer, and the surface decorative member and the synthetic resin foam layer can be damaged. In addition, it is possible to completely separate the target surface decorative member from the synthetic resin foam layer without any skill. Therefore, due to lack of skill, there may be a risk of causing damage to the surrounding surface decorative member that does not cause a problem and necessitating removal of an adjacent surface decorative member that should not be removed, or that the surface decorative member to be removed may be broken. As a result, the work may be more troublesome, or the synthetic resin foam layer adhered to the back surface of the surface decoration member may be peeled off when the surface decoration member is raised, and a repair operation may be required. It is possible to reduce the irrational factors included in the conventional method, such as, and,
It has become possible to provide a method for easily removing the surface decorative member.

The third step may employ a method in which the wire is moved while energizing the wire to generate Joule heat in the wire. By employing such a method, an operator burden required for the operation of moving the wire in the third step is reduced.

Further, when adopting the above-mentioned method of moving a wire while utilizing Joule heat, the wire is connected to one case via both ends thereof, and the case is electrically connected to the case. It is desirable to have battery means for the interior. By performing the third step in such a state, the worker can move the wire while holding the case body with one hand without gripping both ends of the wire, and the work becomes easier. . Further, since the case body and the energizing battery means are integrated, the whole apparatus becomes more compact and the work becomes easier.

FIG. 2 is a partial plan view showing an example of a decorative panel 1 to which the removing method according to the present invention is applied. As shown in FIG. 2, the front face of the decorative panel 1 is formed by planarly arranging surface decorative members 3 and 3 (here, a square ceramic tile is used as an example of the surface decorative member). Is covered by the surface to be. Also, both edges of the decorative panel 1 extending in the vertical direction are formed of a steel frame member 5 having a substantially rectangular hollow cross section.
5. Then, a synthetic resin such as polyurethane is foam-molded in a space formed by the frame members 5 and 5, the surface decorative members 3 and 3, and a flat surface of an upper mold (not shown). By doing
The decorative panel 1 is formed by forming a synthetic resin foam layer 2 and removing the upper die after the hardening of the synthetic resin.
Is composed. Therefore, the frame members 5, 5
The surface decorative members 3 and 3 are integrally bonded to the synthetic resin foam layer 2 through the foaming step and the curing step after foaming. Further, the surface decorative members 3, 3 in the drawing are regularly arranged almost linearly in any of the vertical and horizontal directions. Further, the surface decorative members 3, 3 are separated from each other at a constant equal interval in any of the vertical and horizontal directions, and the vertical and horizontal gaps formed between the surface decorative members 3, 3 are any. ,
It is filled with the joint material 4. Examples of the material of the joint material 4 include a cement-based mortar.

Here, the curing of the synthetic resin foam layer 2 and the joint material 4 is also completed as described above with reference to FIGS. 1A to 1D schematically showing the procedure of the method of removing the decorative panel. A method of removing a decorative panel according to the present invention will be described by taking, as an example, a case where a specific surface decorative member 3 'is removed from the decorative panel 1 thus completed. As shown in FIG. 1 (a), tools to be used for smoothly performing the present method include:
An appropriately sized and shaped driver 6, hammer 7, and
The removal tool 8 is given as an example. The removal tool 8
In this embodiment, the length is about 20 cm and the diameter is
Handle-shaped members 1 at both ends of a steel wire 9 of about 0.2 mm
What fixed 0,10 'is used.

(First Step) FIG. 1A shows an intermediate step of the first step. That is, in the first step, the joint material 4 surrounding the surface decorative member 3 'to be removed is removed over the entire circumference of the surface decorative member 3' by using the driver 6, the hammer 7, and the like. When this step is completed, the surface of the synthetic resin foam layer 2 on the back surface of the joint portion surrounding the target decorative surface member 3 'is substantially exposed all around. (Second step) After the first step is completed, as shown in FIG. 1 (b), the joints formed around the target surface decorative member 3 'by the removal of the joint material 4 are removed. By utilizing a space, a boundary between the surface decorative member 3 'and the synthetic resin foam layer 2 (here, a side surface forming one side of a square ceramic tile and an exposed synthetic resin foam layer adjacent to the side surface) 2) means a wire rod, that is, a steel wire 9 of the removal tool 8. (Third Step) Next, as shown in FIG. 1 (c), while applying tension to the steel wire 9 via the handle portions 10, 10 ', the surface decorative member 3' and its back surface are applied. The steel wire 9 is moved (substantially downward here) along the boundary surface of the synthetic resin foam 2 adhered to the steel wire 9. As the third step proceeds, the bonding area between the surface decorative member 3 'and the synthetic resin foam 2 gradually decreases. Then, as shown in FIG. 1 (d), when the third step is completed, finally, there is no adhesive area between the surface decorative member 3 'to be removed and the synthetic resin foam 2, and the object is removed. The removal of the decorative surface member 3 'from the decorative panel 1 is completed.

[Other Embodiments] (1) In the above embodiment, a pair of detachable handle members 10 and 10 'are used as the handle members of the removal tool 8, but as shown in FIG. A handle member in the form of an integrated case body 11 fixed to the above is also applicable. The use of the integrated handle member 11 as described above has advantages in that the third step of moving the wire can be performed with one hand, and that a force for moving the wire along the back surface of the decorative member can be easily applied. can get.

(2) In the above embodiment, the third step of moving the wire 9 along the bonding surface of the surface decorative member 3 ′ to the synthetic resin foam 2 while applying tension to the wire 9.
In the process, the movement of the wire 9 was substantially based only on the mechanical pulling force of the worker, but it is also possible to use a wire connected to a battery as shown in FIG. That is, by flowing a direct current of a certain voltage or the like through the wire 9, the synthetic resin foam 2 is melted in the wire 9, or Joule heat capable of softening the synthetic resin foam 2 is generated. This is because a method for performing the movement is adopted. As described above, by moving the wire 9 while melting or softening the synthetic resin foam 2 around the wire 9, the synthetic resin foam 2 tries to advance at the interface between the synthetic resin foam 2 and the surface decorative member 3. Since the resistance exerted by the synthetic resin foam 2 on the wire material 9 is reduced and the movement of the wire material 9 is assisted, there is an advantage that the third step is easily performed.

Here, as the wire 9 capable of generating Joule heat, for example, a nichrome wire can be used. Further, as means for energizing the wire, a battery (for example, a commercially available single-type dry battery) means 12 built in the case body 11 as an energizing unit can be used. As described above, by using the battery means 12 built in the case body 11 as the electricity supply means for generating the Joule heat, the detaching means 8 can be operated more easily than the aid of the movement of the wire 9 by heat generation. While making it more compact and easier to handle.

(3) In the above embodiment, a general ceramic tile is used as the surface decorative member 3 provided on the decorative panel 1, but the decorative panel surface decorative member 3 adopting the removing method according to the present invention is used. As long as it has a tiled shape, other materials such as artificial marble, glass, and metal can be used.

(4) In the above embodiment, the surface decorative member 3 has a square shape. However, the surface decorative member 3 may have another square shape such as a rectangle, or various polygons such as a triangle or a hexagon, or a circle. It can be applied to surface decorative members having various shapes such as an oval shape.
