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 to apply and integrate the convex part of the top plate with the concave part of the forefoot by fitting and adhering it. Then, after the adhesive is cured, the adhesive protruding from the fitting portion of the convex portion and the concave portion is polished to finish cleanly.

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

  Further, in the top board structure of the sink described in Patent Document 2, a ceramic top board is placed on the upper surface of the fiber reinforced plastic reinforcing layer straddling the front core and the rear core attached to the front on the front. The ceramic back guard is mounted in an upright state on the fiber-reinforced plastic reinforcing layer on the rear core. Then, the counter material is assembled by filling a joint material made of epoxy resin between the fore-end 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 joint portion is polished, the glaze is removed and the designability of the surface is reduced, so that the polishing is also difficult.

Moreover, in the top plate structure described in Patent Document 1, since only the top plate of the artificial marble and the front ridge are joined with the chip made of plywood with an adhesive, the adhesive strength is higher than that of the uneven fitting structure described above. 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. The purpose is

The top structure according to the present invention is a top having a flat back surface, and a front end fixed to the back surface of the top at a position flush with the front end of the top or at a position retracted from the front end of the top. An adhesive layer, a backing portion fixed to the top plate with a gap on the back side of the front ridge, an adhesive layer filled in the gap and fixing the top plate, the front ridge and the backing portion to each other, and A front-facing portion having one surface fixed to the back surface and the other surface covering the adhesive layer and fixed to the backing portion , wherein the adhesive layer includes the front surface in addition to the gap. It is provided also in the cut part which cuts off the corner | angular part of the back surface of a collar and the joint surface contact | abutted to the said top plate .
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 is also provided in a cut portion formed by partially cutting a corner portion between the back surface of the front heel 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 the cutout can be filled with adhesive, and the joint 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.

In the method of manufacturing the top plate structure according to the present invention, the front wing is adhered to the back surface of the top plate which is flush with the front end of the top plate or at a position retracted from the front end of the top plate with an adhesive. A process, a step of bonding a backing portion to the back surface of the top plate with a gap on the back side of the front plate, and an adhesive layer for fixing the front plate, the top plate and the backing portion by filling the gap with an adhesive And bonding the front finding portion to the back surface of the front eyelid and the backing portion to cover the adhesive layer in the gap, and joining the rear surface of the front eye and the top plate A cut portion formed by cutting a corner portion with the surface in advance is formed integrally with the gap, and the cut portion is also filled with an adhesive of the adhesive layer .
According to the present invention, after bonding the fore-end to the back of the top plate and opening the gap on the back of the fore-end to fix the backing portion, the gap is filled with an adhesive to form an adhesive layer. This makes it possible to firmly fix the forehead and the top board. Further, the adhesive layer can be covered by adhering the front finding portion to the back surface of the front eyelid and the backing portion, and the front finding portion can be exposed and used as a cosmetic material.

Moreover, before the stile is characterized by forming a pre-excised formed by cutout corners of the front back and joint surface abutting the top plate of the stiles in the gap integrally.

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 an AA line longitudinal cross-sectional view of the top-plate structure of the sink shown in FIG. It is the B section enlarged view of the top plate and front fore part which are shown in FIG. (A), (b), (c), (d) is sectional drawing which shows the manufacturing process of 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 backing portion 7 is fixed to the back surface side of the top plate 3 as a reinforcing plate made of, for example, wood. At the position facing the back guard 5 of the top plate 3, the surface of the worker standing up and performing work such as cooking and washing is the front, the surface at the back guard 5 side is the back, and both sides are the sides. In addition, as shown in FIG. 1, the top plate 3 is formed in a substantially rectangular plate shape in which the front side and the back side form a long side, and the side side orthogonal to the long side forms 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 tapered portion 10 in advance on the ceramic hard shell 9 made of high hardness, for example, a water jet is jetted to cut the upper corner portion of the front rod 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. Then, an adhesive made of, for example, an epoxy resin or the like is filled in the gap 8 and solidified to form an adhesive layer S having a predetermined thickness, whereby the top plate 3, the front cover 9, and the backing portion 7 is firmly fixed. Note that the width of the gap 8 is set to be larger than that when the front heel 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. The adhesive made of epoxy resin is difficult to be filled without gaps in the corner between the forehead 9 and the top plate 3 because of its viscosity, but the upper corner between the back surface 9b of the forehead 9 and the joint surface 9a 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. Moreover, since the adhesive reservoir in which the high viscosity adhesive penetrates is formed in the tapered portion 10 formed in the upper corner of the front rod 9 and is integrally formed with the adhesive layer S of the gap 8, the top plate 3 and the front rod 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 adhesive is applied to the front surface of the backing portion 7 and the front rod 9 is adhered, there is a possibility that the front rod 9 may be inclined or misaligned due to a shape error or mounting error of the backing 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 proper change, substitution, etc. are possible in the range which does not deviate from the summary of this invention. Hereinafter, although the modification of the present invention is explained, the same numerals as the same or similar parts and members described in the above-mentioned embodiment will be explained 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 front rod 9 which is filled with the adhesive in the gap 8, the chamfered tapered portion 10 may be replaced with another cut shape, for example, a round honed shape by cutting into a cross section R 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 of ceramic was used in embodiment as a high hardness material which forms top plate 3 in embodiment of this invention or fore 9, the present invention is not limited to embodiment, and it is a crevice which can mutually be 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 adhesive. It can be obtained by the adhesive layer S.
