Description

  The present invention relates to a top plate structure including a top plate and a front plate made of various materials such as ceramics and natural marble in a sink of a system kitchen, for example, and a method for manufacturing the same.

  2. Description of the Related Art Conventionally, a top plate structure (worktop counter) of a sink such as a system kitchen is widely known in which an artificial marble top plate is provided on the top plate. For example, when connecting the artificial marble top plate to the front plate provided on the front surface of the top plate structure of the sink, adhesives are respectively applied to the concave portion formed on the back surface of the front plate and the convex portion formed on the front end portion of the top plate. It is known that it is applied and integrated by fitting and bonding the convex portion of the top plate to the concave portion of the forehead. Then, after the adhesive is cured, the adhesive that protrudes from the fitting portion between the convex portion and the concave portion is polished to achieve a clean finish.

  Moreover, what was described in patent document 1, for example as another top-plate structure is proposed. In this top plate structure, a return edge is formed at the front edge portion of the top surface of the top plate made of plate-shaped artificial marble as the top plate, and a back guard is formed at the rear edge portion. A crosspiece made of plywood is fixed to the front edge portion and the rear edge portion on the back surface of the top plate by bonding, and a front heel made of artificial marble is fixed to the front surface side of the crosspiece at the front edge portion with an adhesive.

  Moreover, in the top plate structure of the sink described in patent document 2, a ceramic top plate is mounted on the upper surface of the reinforcing layer made of fiber reinforced plastic straddling the front core member and the rear core member attached to the front. The ceramic back guard is mounted in an upright state on the fiber-reinforced plastic reinforcing layer on the rear core. A counter is assembled by filling a joint material made of an epoxy resin between the front and the ceramic top plate and between the ceramic top plate and the ceramic back guard.

  However, the above-mentioned top plate structure in which the artificial marble top plate and front plate are unevenly fitted forms a concave portion on the front plate and a convex portion on the top plate in order to increase the attachment strength, and is fitted and bonded together. Although it is fixed, it is difficult to process the concave portion and the convex portion when the top plate and the foreboard are made of a ceramic having a hardness higher than that of the artificial marble. In addition, when the bonded portion is polished, the glaze is removed and the design of the surface is lowered, so that the polishing finish is difficult.

Moreover, in the top plate structure described in Patent Document 1, since the artificial marble top plate and the front plate are merely joined with a plywood crosspiece and an adhesive, the adhesive strength compared to the above-described uneven fitting structure. There was a drawback that was small.
Moreover, in the top plate structure described in Patent Document 2, since the top plate and the back guard are made of ceramic having a hardness higher than that of the artificial marble, it is more difficult to process the concave portions and the convex portions. For this reason, the top plate and the back guard have to be formed in a flat plate shape and placed on the reinforcing layer, and a joint material made of epoxy resin or the like must be filled and fixed in these gaps. Therefore, compared with the concave-convex fitting, there is a defect that the adhesive strength is small like the top plate structure described in Patent Document 1.

  The present invention has been made in view of such a problem, and provides a top plate structure and a method for manufacturing the top plate that can fix the top plate and the front wing with high strength without being unevenly fitted. For the purpose.

The top plate structure according to the present invention includes a top plate, a front plate fixed to the back surface of the top plate, a backing portion fixed to the top plate via a gap on the back side of the front plate, and a top plate filled in the gap. And an adhesive layer for fixing the forehead and the backing part to each other.
According to the top plate structure of the present invention, an adhesive layer is formed by filling the gap between the front plate and the backing portion on the back surface of the top plate to form an adhesive layer. It can be firmly fixed to the backing part, and the water resistance is improved by providing a thick adhesive layer on the back of the joint between the top plate and the front. In addition, it is possible to eliminate the need for polishing finishing of the portion of the adhesive layer. In addition, since the forehead is cut off through the backing part and the adhesive layer, the leading edge can be accurately fixed to the top plate without being affected by errors in the shape of the backing part and the mounting position.
In addition, even if the top plate and front plate are made of high-hardness materials such as ceramics, the top plate and front plate are fixed to a high strength regardless of whether the top plate and front plate are subjected to uneven processing or by bonding with an adhesive applied to the surface. it can.

In addition to the gap, the adhesive layer preferably has a cut portion formed by partially cutting a corner portion between the back surface of the forehead and the joint surface contacting the top plate.
When the gap is filled with adhesive, a cutout such as a taper is provided at the upper corner of the back of the forehead so that the cutout can also be filled with adhesive and the bonding strength between the forehead and the top plate Can be set higher. Therefore, even if the front and top plates are made of a high hardness material such as ceramic, it can be fixed with high strength.

The manufacturing method of the top plate structure according to the present invention includes a step of adhering the front to the back of the top with an adhesive, a step of opening a gap on the back side of the front and adhering the backing portion to the back of the top A step of filling the gap with an adhesive to form an adhesive layer for fixing the front plate, the top plate, and the backing portion; And a step of covering the adhesive layer.
According to the present invention, the front plate is adhered to the back surface of the top plate, a gap is formed in the back surface of the front plate, and the backing portion is fixed, and then the adhesive is filled in the gap to form an adhesive layer. This makes it possible to firmly fix the forehead and the top board. In addition, the adhesive layer can be covered by adhering the front finding part to the back surface and the backing part of the front collar, and the front finding part can be exposed and used as a cosmetic material.

  Further, it is preferable that the front heel has a cut portion formed by cutting a corner portion between the back surface of the front heel and the joint surface contacting the top plate in advance with the gap.

According to the top plate structure and the manufacturing method thereof according to the present invention, the front plate can be firmly fixed to the top plate and the backing portion by the adhesive layer filled in the gap, and the polishing finish of the adhesive portion can be made unnecessary. In addition, by providing a thick adhesive layer on the back surface of the joint between the top plate and the front plate, water penetration is prevented and water resistance is improved.
In addition, since the front wing is cut off from the backing part through the gap of the adhesive layer, it can be accurately fixed to the top plate without being affected by the shape error or mounting error of the backing part. .

It is a principal part perspective view which shows the top plate structure of the sink by embodiment of this invention. It is the AA longitudinal cross-sectional view of the top plate structure of the sink shown in FIG. FIG. 3 is an enlarged view of part B of the top plate and the forehead portion shown in FIG. 2. (A), (b), (c), (d) is sectional drawing which shows the manufacturing process of a top-plate structure.

Hereinafter, a top plate structure of a sink, for example, a sink 1 such as a system kitchen, according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.
A sink 1 in a system kitchen or the like according to the embodiment shown in FIG. 1 is provided with a top plate (worktop counter) 3 on an upper part of a box-shaped cabinet 2, for example. The top plate 3 is made of a high-hardness material, for example, ceramic, and is provided with a recessed sink 4 for washing cooking utensils or the like in a partial area, and a faucet (not shown) is attached in the vicinity of the sink 4. Yes. A back guard 5 erected upward is fixed to the back side (back side) of the top plate 3. The sink 4 may not be provided on the top 3.

  Moreover, in the top plate structure 14 of the sink 1 shown in FIG.2 and FIG.3, the back bonding part 7 is being fixed to the back surface side of the top plate 3 as a reinforcement board which consists of wood, for example. A surface on which the worker stands and performs work such as cooking and washing at a position facing the back guard 5 of the top plate 3 is a front surface, a surface on the back guard 5 side is a rear surface, and both sides are side surfaces. As shown in FIG. 1, the top plate 3 is formed in a substantially rectangular plate shape in which the front side and the rear side have long sides and the side surface orthogonal to this has a short side.

A front saddle 9 is fixed to the front surface of the backing portion 7 through a gap 8. In this embodiment, the front lid 9 is fixed at right angles to the top plate 3 at an overhanging position slightly retracted from the front end of the top plate 3, that is, on the back-attached portion 7 side. It may be fixed flush with the front end.
Like the top plate 3, the front plate 9 is made of a high-hardness material ceramic, and the upper corner between the joint surface 9 a with the top plate 3 and the back surface 9 b facing the gap 8 is obliquely cut in advance and tapered. Part 10 is formed. The space of the tapered portion 10 constitutes a space integral with the gap 8. In order to form the taper portion 10 in advance on the ceramic front heel 9 having high hardness, for example, it is obtained by ejecting a water jet and cutting the upper corner portion of the front heel 9.

Further, a front finding portion 12 is fixed as a cosmetic material on the back surface of the front heel 9 and the lower surface of the back attachment portion 7, and the front finding portion 12 covers the gap 8 between the front heel 9 and the back attachment portion 7. ing. The gap 8 is filled with an adhesive made of, for example, an epoxy resin and solidified to form an adhesive layer S having a predetermined thickness, whereby the top plate 3, the front plate 9, and the backing portion 7 is firmly fixed. In addition, the width of the gap 8 is set to be larger than that in the case where the front collar 9 and the backing portion 7 are fixed by applying an adhesive.
Then, the adhesive layer S is covered with the front finding portion 12 so as not to be seen from the outside. These members including the top plate 3 and the front wing 9 constitute a top plate structure 14.

The top plate structure 14 of the sink 1 according to the present embodiment has the above-described configuration. Next, a method for manufacturing the top plate structure 14 will be described with reference to FIG.
In FIG. 4 (a), a ceramic forehead 9 is temporarily fixed vertically to the top plate 3 with an instantaneous adhesive at a position slightly retracted from the front side with respect to the ceramic top plate 3. Next, a predetermined gap 8 is opened on the back side of the front ridge 9, and the backing portion 7 is bonded to the top plate 3 with an adhesive. In the present embodiment, the backing portion 7 is disposed on substantially the entire surface of the top plate 3 to support and reinforce the ceramic top plate 3.

In this way, an elongated groove is formed in the horizontal direction as the gap 8 between the front heel 9 and the backing portion 7, and the gap 8 is filled with an adhesive made of epoxy resin. Since the adhesive made of epoxy resin is viscous, it is difficult to fill the corners of the front heel 9 and the top plate 3 without any gaps, but the upper corner between the back surface 9b and the joint surface 9a of the front heel 9 is cut off. Since the taper portion 10 is formed, the adhesive flows well into the taper portion 10 and can be filled. For this reason, the ceramic top plate 3 and the forehead 9 can be firmly fixed by the adhesive layer S having a predetermined thickness.
Finally, the decorative material of the front finding portion 12 is brought into contact with the backing portion 7 and the back surface 9b of the front saddle 9, and is fixed with an adhesive. Thus, the assembly of the top plate structure 14 can be completed.

As described above, according to the top plate structure 14 of the sink 1 and the manufacturing method thereof according to the present embodiment, the ceramic top plate 3 that is a high-hardness material and the front plate 9 are formed between the backing portion 7 and the predetermined part. It can be firmly fixed by the adhesive layer S having a thickness. In addition, since the adhesive pool into which the adhesive having high viscosity penetrates is formed in the tapered portion 10 formed at the upper corner of the front plate 9 and is formed integrally with the adhesive layer S of the gap 8, the top plate 3 and the front plate 3 9 has high adhesive strength.
Further, the adhesive does not protrude from the gap between the top plate 3 and the front heel 9, and it is not necessary to polish the bonded portion, and an adhesive layer having a predetermined thickness is formed on the back surface of the joint between the top plate 3 and the front heel 9. Since S is formed, it prevents water from entering from the front 9 side and has high water resistance.

Further, in order to fix the front wing 9 at a position set back to the top plate 3, the position of the top plate 3 and the front heel 9 is adjusted by the adhesive layer S when the top plate 3 and the front heel 9 are aligned. It is possible to absorb the dimensional variation of the alignment.
In addition, when the front cover 9 is adhered by applying an adhesive to the front surface of the back-attached portion 7, the front-end 9 may be inclined or displaced due to a shape error or attachment error of the back-attached portion 7. However, the adhesive layer S can be used to cut the edge of the backing portion 7 and attach the front collar 9 to the top plate 3 using a jig or the like, which is excellent in design.

  In addition, the top plate structure 14 of the sink 1 by this invention is not limited to embodiment mentioned above, A suitable change, substitution, etc. are possible in the range which does not deviate from the summary of this invention. Hereinafter, modifications of the present invention will be described, but the same or similar components or members described in the above-described embodiment will be described using the same reference numerals.

In the above-described embodiment, the corner portion of the joint surface 9a with the top plate 3 of the front heel 9 is cut off to form the tapered portion 10 to improve the joining property between the top plate 3 and the front heel 9, but the tapered portion 10 need not necessarily be formed. Even in this case, the gap 8 has a gap sufficient to cut off the front rib 9 and the backing portion 7. Since the adhesive layer S is formed by filling the gap 8 with the adhesive, The bonding strength with the top plate 3 is sufficiently high.
In addition, regarding the upper corner portion of the forehead 9 filled with the adhesive in the gap 8, instead of the chamfered taper portion 10, it may be cut into another cut shape, for example, a cross-section R shape to form a round honing shape, A stepped shape may be cut in a step shape, and these form a cut portion including the tapered portion 10. Further, not only the forehead 9 but also an upper corner portion facing the gap 8 of the backing portion 7 may be formed with a cut portion and filled with an adhesive.

  Moreover, although the thing made from a ceramic was used in embodiment as a high-hardness material which forms the top plate 3 and the front heel 9 in this invention, this invention is not limited to embodiment, The recessed part which can be mutually fitted As long as it is a hard material that is difficult to process, such as a convex portion, it can be applied to a top plate or an outpost made of other materials. For example, a stone such as natural marble may be used.

  In the top plate structure according to the present invention, the top plate and the front plate may not be a high-hardness material, and the present invention can be applied even if a material such as artificial marble or artificial marble or other materials is used. In other words, the top plate structure according to the present invention has a high adhesive strength between the top plate, the front plate, and the backing portion without forming a concave-convex fitting portion and having a high adhesive strength that cannot be obtained by applying a thin layer of adhesive. It can be obtained by the adhesive layer S.
