Description

[Detailed description of the invention] This invention relates to a counter connection structure.

BACKGROUND ART Conventionally, counters such as kitchen tables used in system kitchens have been connected to each other using adhesives. That is, as shown in FIG. 1, reinforcing bars 3.4 are fixed to the back surfaces of counter bodies 1, 2 made of artificial marble to form counters 5, 6'i, and the sides of both counters 5, 6 are protruded. They were also connected together with an adhesive 7. 8 is the adhesive 7 (
It is a pick-up material.

However, since both counters 5 and 6iJ: are connected only by the adhesive force of the adhesive 7, there is a problem that the connection strength is weak. Another problem was that it was difficult to level the upper surfaces of both counters 5 and 6, making the construction complicated.

Therefore, an object of the present invention is to improve the connection strength;
Moreover, it is an object of the present invention to provide a counter connection structure that allows reliable leveling of the top surface of the counter and is easy to construct.

An embodiment of the present invention will be described with reference to FIGS. 2 to 6. As shown in FIGS. 2 and 3, this counter connection structure includes a first counter 9 and a second counter 10.
It is applied to the connection of , and in the first color/li9,
By cutting and removing the reinforcing bar 12 attached to the edge of the back surface of the counter body 1 at two locations along the main body joint surface 11a, recesses 13a and 13b surrounded by the cut end surface of the reinforcing bar 12 and the back surface of the counter body 11 are formed. At the same time, in the second counter 10, a part of the reinforcing bar 15 attached to the edge of the back surface of the counter main body 14 is made to protrude outward from the main body joint surface 14a at two locations to correspond to the recesses 13a and 13b. Convex portions 16a, 16b and f are formed, and these convex portions 16a.

16b? While fitting into the recesses 13a and 13b and bonding with adhesive 17, both main body joining surfaces 11a,
14a are butted against each other and bonded with adhesive 13.

In this case, the first counter 9t/'i, both recesses 13a

A backup positioning groove 18 is provided in the reinforcing bar 12 between 13b.
form. Also, both counters 9. IO has its counter body 11.14 made of polyester-based artificial marble, and reinforced crosspiece 12.15i artificial marble.

Constructed of wood, etc.

The procedure for connecting both counters 9 and 10 is as follows. That is, as shown in FIG. 4, the convex portion], 6a,
Apply adhesive 17 to the top surface and both side surfaces of 16b 1, and connect the convex + B16a, 16b k concave portions 13a, 13
b, and as shown in FIG.
Between a and 16b, the entire backup 19 is placed between both reinforcing bars 12.15, and the adhesive 17 is filled between the counter bodies 11.14, and the counters 9 and 10'i are pressed from both sides in the direction in which they approach each other. , as shown in FIG. 6, a part of the adhesive 17 is made to protrude from between the counter bodies II and 14. In this way, the convex portions 16a and 16b are connected to the concave portion 13a.
, 13b, and both counter bodies 1.
After the main body joint surfaces 11a and 14a of 1.14 are butted and bonded, wait for the adhesive 17 to harden and then attach the counter main body 11.
The raised portion of the adhesive 17 protruding from the adhesive 14 is removed using a sand vapor or the like, and the surface of the adhesive 17 is finished to be flush with the surface of the gold counter, as shown in FIG. In addition, as the adhesive 17, a urethane-based adhesive, a polyester-based adhesive, an acrylic-based adhesive, or the like is used.

In this way, the main body joint surface 1 of both counter bodies 11.14
1a, 14a f Not only are they butt-bonded with the adhesive 17, but also the concave portions 13a are attached to the convex portions 16a, 16b'.
, 13b, the adhesive force of the adhesive 17 causes the convex portions 16a, 161) and the concave portions 13a, 13b to
By adding mechanical strength due to the fitting of both counters 9 and 1,
0 connection strength can be improved. Moreover, the recess 1

13b and the convex portions 16a and 16b f, each with a reinforcing bar 1
2, 15, both counter bodies 11.14
By setting the thicknesses of the convex portions 16a,
By simply fitting the counters 16b into the recesses 13a and 13b, the upper surfaces of both counters 9.10 can be leveled with high precision, and the work of connecting both counters 9.10 can be easily performed.

A second embodiment of the invention is shown in FIG. In other words, the counter connection structure with counter 2 is as shown in the same figure.
The reinforcing bar 15 of the counter 22 is made to protrude outward over the entire range of the main body joint surface 14a to form a convex portion 20, and the reinforcing bar 12 of the counter 22 is cut and removed within the range of the main body joint surface 11a to form a recess 21'. 2, and the convex portion 20 is inserted into the concave portion 2.
1', and the main body joint surface 11a,
14a and f are butted and glued together. According to this embodiment, in addition to achieving the same effects as the above embodiment,
Since the width of the convex portion 200 is wide, the connection strength can be further improved than in the above embodiment.

A third embodiment of the invention will be described with reference to FIGS. 8 to 11. In other words, this counter connection structure
In addition to the embodiment shown in the figure, as shown in FIG.
Reinforcement beam 15 located between both convex portions 16a and 16b of 5
Another bolt insertion hole 26 is provided in the hole 26, as shown in FIG.
By passing the bolt 27 through each bolt insertion hole 26, 24 and fastening the NAND 28 (FIG. 10), both counters 2
This is a combination of 3 and 25. The rest of the structure is the same as the embodiment shown in FIG.

The procedure for connecting both counters 23 and 25 is almost the same as that of the embodiment shown in FIG.
In the embodiment shown in the figure, both counters 9 and 10 are manually pressed from both sides to apply a portion of the adhesive 17 onto the counter body 11.
, 14, in this embodiment,
By tightening the bolt 27 as shown in FIG. 10, both counters 23 and 25 are brought closer to each other, and
As shown in the figure, a portion of the adhesive 17 is applied to the counter body 11.
Make it stick out from 14.

In this way, in addition to the structure of the first embodiment (FIG. 2), since both counters 23 and 25 are tightly connected by bolts 27 and nuts 28, both counters 2 are more tightly connected than in the above embodiment.
3, 25 connection strength can be improved. Moreover, bolt 27
．． By tightening the nut 28, the pressure of the adhesive 17 against the counter body 11.14 can be increased to improve the adhesive strength, and the width of the adhesive 17 between the counter bodies 23 and 25 can be made extremely thin, so that the seam can be It can be made inconspicuous and improve your aesthetic appearance.

As described above, in the counter connection structure of the present invention, the reinforcing bar attached to the back surface of the main body along the joint surface of the counter main body is cut and removed within a certain range, thereby surrounding the cut end surface of the reinforcing bar and the back surface of the main body. A first counter having all the concave portions formed therein, and a part of the reinforcing crosspiece attached to the back surface of the counter body, with convex portions corresponding to the four portions being formed so as to protrude outward beyond the bonding surface of the main body, and the convex portions. is fitted into the recess and is bonded to the second counter, and the main body bonding surface is butted and bonded to the main body bonding surface of the first counter, so that the connection strength can be improved and the level alignment of the top surface of the counter can be improved. It has the advantage of being reliable and easy to install.
