The head portion 35a extends downward through a through hole 36 opened in the middle, and the head portion 35a is brought into contact with the lower protrusion portion 31b.

With this configuration, the counters A and B can be aligned and finely adjusted in the vertical and longitudinal directions, and the joining ends 29 and 30 of the counters A and B can be integrated.

(c) Problems to be solved by the invention However, in the above-mentioned conventional connection structure of counters A and B, tensile stress is applied to counters A and B due to expansion and contraction of counters A and B after connection.
This tensile stress concentrates on the front surface of B, and this tensile stress causes an opening (or tear) at the front surface of the joint, causing cracks in the joint material, causing water leakage from the same point to the lower part, and damaging the aesthetics of the counter. It was also becoming a detriment to the economy.

An object of the present invention is to provide a counter connection structure that can solve the above problems.

(d) Means for Solving the Problems The present invention is a counter connection structure in which the ends of the counter that intersect with each other at a predetermined angle are connected by a connecting device, and the connecting device is connected to a) both ends of the counter. b) A connecting plate made of a bent plate that is installed between the front lower surfaces and has long holes at both ends, and (b) female screw holes provided on the front lower surface of both ends of the counter, and through the long holes of the connecting plate. The present invention relates to a counter connection structure characterized in that it is comprised of a fixing metal fitting consisting of a connection bolt that is screwed into the female threaded hole and capable of fixing the connection plate to both ends of the counter.

The present invention also provides a counter connection structure in which the ends of the counter that intersect at a predetermined angle are connected by a connecting device, and the connecting device is installed in a) between the front lower surfaces of both ends of the counter. b) a connecting plate made of a bent plate with elongated holes at both ends; b) connecting bolts embedded in the front lower surface of both ends of the counter; and screwing to the connecting bolts through the elongated holes of the connecting plate; This invention relates to a counter connection structure characterized in that the connection plate is constituted by a fixing fitting consisting of a nut that can be fixed to both ends of the counter.

(E) Functions and Effects With the above configuration, the present invention has the following effects.

As described above, the present invention provides a connection in which the fixing fitting is substantially installed between the front lower surfaces of both ends of a pair of counters where they are joined, and is made up of a bent plate with elongated holes provided at both ends. Since it is composed of a plate and a connecting bolt inserted through the same elongated hole, the fixing metal fittings installed on the lower front side of the counter prevent the opening that may occur at the front of the joint due to expansion and contraction of the counter. Also, tearing can be reliably prevented. In addition, the fixing metal fittings can be hidden behind the counter surface, and the top surfaces of the joint portions of the counter can be made flush with each other, thereby improving the aesthetic appearance of the counter joint portion.

Furthermore, even if the female screw holes and connecting bolts provided on the bottom surface of the counter used as fixing fittings are slightly misaligned, the connecting bolts can be easily inserted into the same female screw holes as long holes are provided in the connecting plates used as fixing fittings. It is possible to easily screw a nut onto a connecting bolt, and to easily connect a counter with a nut.
