Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a piping connection device for water heaters, bathtubs, hot water heaters, and other appliances that require piping connection work.

(Prior art) As a conventional device of this type, a water heater or other appliance that requires piping connection work is attached to a wall surface via a mounting bracket, and each internal piping of the appliance and each corresponding external piping are connected to each other. In this case, the piping connection work procedure is to first lay each external piping that is the base pipe, then attach the mounting bracket to the wall surface and attach the equipment to it, and finally connect each internal piping of the equipment. It is common practice to connect directly to each external piping.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional method, the mounting bracket is attached to the wall separately from each external piping work, and according to this, the fixture is then attached to the mounting bracket. When this occurs, misalignment occurs between each internal piping and each external piping of the appliance, resulting in a problem that it becomes difficult to connect the two.

(Means for Solving the Problems) The present invention is intended to provide a device that eliminates the above-mentioned problems, and is capable of attaching a water heater or other equipment that requires piping work to a wall surface via a mounting bracket. In a device that connects each internal piping of the appliance and each corresponding external piping, the mounting bracket is connected to a bottom plate having a size approximately equal to the bottom surface of the appliance, and a height that rises from the bottom plate and is approximately equal to the height of the appliance. and a rising plate having a wall surface, and the rising plate is provided with a mounting part to the wall surface and an engaging part for locking the appliance,
Each joint pipe connected to each external pipe is provided on the bottom plate, and the connecting end of each joint pipe with each internal pipe is arranged opposite to the connecting end of each internal pipe.

(Function) The present invention has the above-mentioned configuration. According to this, when installing each external piping, it is possible to perform the connection work between each external piping and each joint pipe of the mounting bracket, and to connect each external piping and each joint pipe. The mutual positional relationship of the metal fittings is specified through each joint pipe, so when the fitting is attached to a wall surface and a device is attached to the fitting, misalignment between each internal piping and each external piping of the device will be avoided. The connection between the two can be made easily and reliably. Moreover, the space in which the device is installed can be secured in advance by using the mounting bracket.
