Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joining structure for top plates that can easily and accurately match the levels of a plurality of plates that are to be flush with each other.

For example, in a system kitchen in which a kitchen sink, a cooking table, a gas stove, etc. are integrated, a plate material such as decorative plywood or microwave concrete is used for the top plate. Nowadays, such system kitchens have become large in size, which imposes restrictions on manufacturing and transportation, so the above-mentioned top plate is formed from a plurality of plate materials. In such a case, each board is mounted and fixed so that it is approximately at the same height, but it is difficult to make the entire top board flush, and slight differences in level occur. This level difference is caused by the overall height difference or the difference in warp deformation of each plate material. Conventionally, adjusting to eliminate such a level difference is troublesome as it requires a spacer according to the level difference.
In addition, fine adjustment was difficult.

The above-mentioned problems occur not only in the top plate of system kitchens, but also in wall panels, which are formed by connecting a plurality of plates into a single piece.

The present inventor has created the present invention in view of the above-mentioned problems and to effectively solve the problems.

The purpose of the present invention is to provide a system kitchen in which two or more plate-like members are joined together to form a single piece, such as a top plate, a panel forming a wall surface, and a ceiling plate, in which each of the above-mentioned plates is used. The object is to easily adjust the level so that the joints of the shaped members are flush with each other, and also to perform delicate level adjustment.

Therefore, in order to achieve the above object, the present invention uses a channel-shaped jig to adjust the surface level of two top plates arranged with their ends facing each other and join them at multiple points in the mutually connected parts. A height difference is formed on the open end side of the jig, and the high part of the step is placed on the joint side of one of the top plates, and the low part is placed on the joint side of the other top plate. At the same time, at least one insertion part is formed in each of the high part and the low part, and the insertion part of one of the high part and the low part is formed into an elongated shape such as a long hole or a notch, so that the high part and the low part Nut members are embedded in each of the two top plates corresponding to the insertion portions in the lower part, and bolt members that are screwed into these nut members are inserted into the insertion portions to separate the two top plates into one sheet. The gist is that they were joined in a shape.

A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a plan view of the system kitchen. A system kitchen 1 is placed in a corner of a room, and its top plate 2 consists of two top plates: a top plate 2a on the sink side and a top plate 2b on the gas stove side. The two top plates 2a and 2b are in contact with each other at each part, and a level adjustment device 4 according to the present invention is provided on the lower surface of this joint 3.
For example, there are three locations.

FIG. 2 shows the arrangement of the level adjustment device 4.
Further, FIG. 3 shows how the level adjustment device 4 is installed. The level adjustment device 4 consists of a hardware 5 formed by bending a metal plate into a channel shape with a U-shaped cross section, and two chisel bolts 6 and 7. Hardware 5 is the fourth
As shown in the figure, steps 5b, 5b are formed on the upper edges of the bent pieces 5a, 5a on both sides, and a hole 5c and a notch 5d are formed in the center, through which the bolts 6, 7 are inserted. ing. The cutout portion 5d may be formed as a long hole, thereby allowing position adjustment. The bolts 6 and 7 are inserted through the holes 5c or the notches 5d through round washers 8.

On the other hand, nuts 9 are fixedly mounted on the top plates 2a and 2b to be screwed into the fly bolts 6 and 7 and to be integrally connected. In this embodiment, the top plates 2a and 2b constitute a special decorative plate as shown in FIG. They are formed together. Therefore, the nut 9 is constructed by joining a nut portion 9a and a metal plate 9b forming a flange by spot welding or the like, and with the nut portion 9a inserted into a hole 11a drilled in the GRC 11, the GRC 11 is attached to resin concrete. 10, it is fixed to the top plates 2a, 2b. The fixed position of the nut 9 is the top plate 2a, 2b.
It is set to match the dimensions of the hardware 5 at a location close to the joint 3 of the metal fitting 5. In this embodiment, the length of the nut portion 9a is configured such that its tip portion protrudes from the lower surface of the top plates 2a, 2b in order to ensure a sufficient threaded portion. In such a protruding state of the nut part 9a, since the metal object 5 is formed to have a channel part, the tip of the nut part 9a faces the channel part, so that no trouble occurs in the assembled state. At least three pairs of nuts 9 for fixing the bolts 6 and 7 are provided close to the joint of the top plates 2a and 2b and embedded in the lower surface thereof.

Next, how to use the level adjustment device 4 will be explained. In FIG. 3, the bent pieces 5 on both sides of the hardware 5
At the upper edges of 5a and 5a, the high portion 5a-1 is brought into contact with one of the top plates 2a, and in this state, the hinge bolt 6 is screwed into the nut 9. Then the other top plate 2b
Then, screw the bolt 7 into the nut 9 through the notch 5d of the hardware 5, and while adjusting the threaded state of the bolt 7, adjust the height of the surface of the top plate 2b to the height of the top plate 2a. Match the height of the surface. On the side of the lower part 5a-2 of the hardware 5, the other top plate 2b
Since the level of the top plate 2b is adjusted, when the thickness of the top plate 2b is different from that of the other top plate 2a, even if the top plate 2b is particularly thick, the heights of the surfaces can be made to match. In this way, the level adjustment device 4 is connected to the top plate 2.
Three joints 3 are provided for the joints 3 of the top plates 2a and 2b, and the heights of the surfaces of the top plates 2a and 2b are matched to make them flush.

In the above, the high part 5a-1 of the hardware 5 makes two line contacts with the lower surface of the top plate 2a, so even if it is tightened with one post bolt 6, no rattling occurs. Further, the hardware 5 is formed to have a channel portion in consideration of the fact that the nut 9 protrudes downward from the lower surface of the top plates 2a, 2b.

The fifth example is a modified embodiment of the level adjustment device according to the present invention. In this embodiment, two nuts 9, 9 are buried in the top plate 2a side, and two nuts 9, 9 are buried in the top plate 2a side of the hardware 5.
The sides are elongated and two post bolts 6, 16 are arranged. According to such a configuration, it is possible to eliminate warping that occurs near the joint portion 3 of the top plates 2a and 2b. In addition, since it is fixed at two points, the lower surface of the top plate 2a and the high part 5 of the hardware 5
It is not necessary to bring them into contact with a-1, and rattling can be prevented even if they do not come into contact with each other.

Two top plates 2 in which the nut members 9 are embedded
a, 2b are joined by bolt members 6, 7 via a channel-shaped jig 5 having height differences 5b, so even if the material of the top plates 2a, 2b does not allow the use of wood screws, they can be joined in one piece. I can do it. In addition, the jig 5 is made into a channel shape and two top plates 2 are connected.
Not only can the rigidity in the direction extending between a and 2b be increased, but also the top plates 2a and 2b have high deformation strength in the front and back direction because they are connected by the screwing of the bolts 6 and 7 and the nut 9. Even if it is, it can be pulled strongly and corrected. In addition, in the present invention, the jigs 5 are provided at multiple locations in the joint portion 3, so that the top plates 2a and 2b may be joined at a 45° angle as shown in FIG. Even if the lengths of the joint parts 3 are different, as in the case, a plurality of nuts 9 are buried at equal intervals in the top plates 2a and 2b in advance, and the appropriate nuts 9 and 9 are selected from among them. By screwing together the butterfly bolts 6 and 7, the top plate 2a,
2b can be joined, and this also provides high versatility.

As is clear from the above explanation, according to the present invention,
By simply adjusting the tightness of fastening means such as bolts and wood screws, the level of the joint between two adjacent plates can be easily and subtly adjusted. It can also be adjusted. Further, by adjusting at three points, warpage in the vicinity of the joint can be corrected.
Furthermore, the level adjustment device is extremely simple in shape and structure, and can be manufactured at low cost.
