2. Description of the Related Art Conventionally, for example, an electric floor heating panel or a hot water floor heating panel or the like having a heating section built in a floor material, a connection portion of a heating function section such as an electric heater or a hot water pipe, has a surface.
In a configuration that does not protrude from the outer surface such as the back and side surfaces, a concave groove that protrudes fruits on one side of the panel and inserts fruits on the other side so that the panel does not have directionality. There is a configuration in which the panel is fixed from the surface with a wooden screw or the like without using the actual structure for forming the panel. However, in such a configuration, wood screws for fixing appear on the surface of the panel.

[0003] Therefore, two types of panels are manufactured, one in which a fruit is formed on both sides of the panel and the other in which a groove for inserting the fruit is formed on both sides of the panel. Although it has been tried to prevent wood screws and the like from appearing on the surface, two types of panels must be manufactured.

[0004]

In order to solve such a problem, as shown in FIG. 6, a concave groove 2b is formed on both side surfaces of a panel 1a, and a space between opposing concave grooves 2a of a panel 1a to be connected is formed. Although there is a connection form in which the actual employee 3a is fitted, the actual employee 3a is inserted into the concave groove 2a of one panel 1 and the actual actual employee 3a is inserted.
When nailing is performed by penetrating the lower wall of the groove 1a and the concave groove 2a, the employee 3a tends to be inclined downward, and the groove 2a of the other panel 1 may be inserted into the fixed employee 3a. There was a problem that it might not be possible.

An object of the present invention is to solve such a problem, and it is an object of the present invention to provide a panel connection structure capable of easily connecting panels regardless of the inclination when nailing is performed on a ground. Is what you do.
