Abstract

PURPOSE:To reduce the size of a groove of joining portion to the minimum, to prevent entering of waste and dust, to eliminate the trouble of caulking process for filling up the groove and to improve the appearance by previously forming a notch groove at a bending portion. CONSTITUTION:A notch groove 50 is formed in the direction of depth of a roof on the side where the kitchen roof is joined, and according to the notch groove 50, two kitchen roofs are bent at right angles to be joined to each other. The notch groove 50 is formed to reduce the roundness produced by board thickness of the top plate when it is bent to the minimum, two roofs having the working of shapening bending of the roofs are bent at right angles according to the notch grooves 50. Back surfaces of bent pieces 20a, 20b are confronted with each other in such a manner that the upper surfaces of two roofs are in flusk state and tightened at two or three places by bolts and nuts to be connected. When such a method of joining roofs by bending according to the notch groove 10, no showy groove is formed at a joining portion, and caulking for filling up the groove is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for joining metal kitchen top plates used in system kitchens and the like.

[Prior Art and Its Disadvantages] Conventionally, in metal kitchen top plates used in L-shaped system kitchens, the following methods have been used to join the metal kitchen top plates at some corners. That is, in FIG. 3, one end of each of the two metal kitchen top plates 1a and lb is bent at a right angle, and the back surfaces of the bent pieces 2a and 2b formed by the bending are made to face each other, and these bent pieces 2a and 2b are made to face each other. There is a method of tightening and joining the pieces 2a and 2b using fastening means such as a port nut.

According to the above joining method, for example, a stainless steel kitchen top plate has a thickness of approximately [■], and when this kitchen top plate is bent at right angles as shown in Fig. Grooves 3 are created between the plates. This groove 3 is due to the roundness H caused by the thickness of both kitchen top plates. However, due to the presence of this groove 3, filth generated during cooking, small particles, etc. tend to accumulate there, resulting in unsanitary conditions and a very unsightly appearance. Therefore, as a method to eliminate the above drawback, the groove 3 is filled with caulking agent 4,
It was considered to make it flush with the metal kitchen top plate mentioned above, but even though it could solve the problem of unsanitary conditions due to accumulation of small dust, the material of the metal top plate and the kneeling agent However, due to the difference in color tone, etc., the problem of aesthetic appearance remained unsolved. [Object of the Invention] The present invention was made to solve the above-mentioned drawbacks, and In the method of joining by bending one end of each side, the groove at the joint part is made as small as possible to prevent dirt and other debris from entering, and it also eliminates the trouble of caulking to fill the groove, improving the appearance. The purpose of this invention is to provide a method for joining metal kitchen tops to create a clean and simple structure.

[Example] Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a sectional view of a main part of a stainless steel kitchen top plate according to the present invention, and is a sectional view of the kitchen top plate before one end of the top plate is bent. A notch groove 50 is formed in the depth direction of the top plate on the joining side of the kitchen top plate, and a cutout groove 50 is formed in the direction of the arrow shown in the figure in order to join the two kitchen top plates based on this notch groove 50. can be bent at right angles. This notch groove 50 is.

It is formed to minimize the roundness caused by the thickness of the top plate when it is bent, and has the function of sharpening the bending process of the top plate.

Figure 2 shows two kitchen top plates shown in Figure 1 with cutout grooves 50.
The bent pieces 20a, 20 are bent at right angles based on
FIG. 3 is a cross-sectional view of a main part of a structure in which the back surfaces of the two top plates are faced to each other so that the upper surfaces of the two top plates are flush with each other, and are fastened and joined at two or three places with bolts and nuts. In this way, the notch groove 5
If the method of bending and joining the top plate based on 0 is used, no conspicuous grooves will be formed at the joints as in the conventional method, and therefore no caulking process is required to fill the grooves.

A double-sided adhesive tape BO is interposed between the folded pieces 20a and 20b.
It is used for temporary adhesion before joining 0a and 20b with bolts and nuts. This double-sided adhesive tape 80 is not necessarily used, but may be used as needed.

Although bolts and nuts are shown as fastening means in the above embodiments, it goes without saying that the present invention is not limited to these means.

[Effects of the Invention] The present invention achieves the following effects by adopting the above-described configuration. Namely.

When both metal kitchen top plates are bent at right angles and joined together, a notch groove is formed in advance at the bending point, so the thickness of the top plate at the bending point becomes thinner and can be bent sharply. That is, the roundness caused by the thickness of the top plate can be made extremely small.

Therefore, when both top plates are joined together, the grooves created at the joint on the top surface of the top plate become extremely small and unnoticeable.
Dirt and other garbage from cooking will not get into the grooves, causing unsanitary conditions or damaging the appearance of the top plate.

[Brief explanation of the drawing]

FIG. 1 is a cross-sectional view of the metal kitchen top plate according to the present invention before bending, and FIG. 2 is a cross-sectional view showing the joint structure of both metal kitchen top plates according to the present invention. FIG. 3 is a cross-sectional view showing the joining structure of a conventional metal kitchen top plate. 20a, 20b...bent pieces, 50...notch grooves.

Claims (1)

[Claims] In the method of bending one side end of each of both metal kitchen top plates at right angles, making the back surfaces of the formed bent pieces face each other, and joining these bent pieces with an appropriate joining means, A method for joining metal kitchen top plates, characterized in that, when one end of each of the kitchen top plates is bent at a right angle, a notch groove is formed in advance at the bending point of the top plate.
