The present invention relates to a prefabricated heating mat having a double electrode that is installed in the building floor or wall and used for heating, and the prefabricated heating mat is laminated in the order of insulation-insulation sheet-power sheet-film heater-mat finisher And a square type prefabricated heating mat having a power connection portion formed at four corners. When combined in one piece, the electrodes at both ends of the film heater and the power sheet are arranged side by side, and the upper and lower electrodes are joined at the corners. The circular connection terminal is fastened to form a double electrode with doubled current capacity. When assembling, connect the power connector to the joint of the arranged heating mat, and connect the wire integrated power connector connected to the temperature controller to the side of the heating mat. The power supply of the thermostat is connected to each heating mat without overload through the power circuit of the double electrode. It characterized in that the one supply.

Prefabricated heating panels or heating panels that heat with electricity as energy are already widely used. A general heating panel is manufactured by arranging heating wires, which are heating elements, on a solid insulation panel in a manufacturing plant. The heating panels are standardized to dozens of sizes to be combined in a matrix to various construction areas, and a plurality of construction panels are combined to a construction area during heating construction. After grasping the heating panel specification, it is constructed by securing a standard product, and the gap area without a standard product is filled with a gap with a heat insulating material of the same thickness, and then the wires of the thermostat are connected in parallel to the heating panel.

The heating panel using the heating wire has a low heat transfer efficiency, takes a lot of time for heating, and increases the production cost and logistics costs due to the production of standard products of various sizes, and in particular, heating using the heating wire generates a lot of electromagnetic waves. It is a situation that affects health and is increasingly being avoided.

In order to solve the problem of the heating panel, a film heater, which is a planar heating element that emits far infrared rays, has been developed and widely used. The film heater is manufactured in the form of a roll in which the same pattern is repeated, in which carbon particles, which are high resistance materials, are coated on a PET film in parallel thin lines and copper electrodes are formed at both ends. It is a far-infrared heating element that emits heat by carbon particles when power is supplied.

Film heaters emit heat evenly over the entire film compared to the general heating wire heating panel, and can feel warm radiant heat by the effect of far-infrared radiation, save electricity cost, rarely generate harmful electromagnetic waves, and have excellent smoothness and durability.

In general, heating of film heater attaches insulation to floor of building, cuts and arranges rolled film heater on insulation, and fastens crimp terminals to both ends of film heater or solders with connecting wire, respectively. Connect the same wires connected to the film heaters of the same poles and connect them with a thick wire, insulate each connecting line with insulation tape, connect them in series or parallel with the power line of the thermostat, and check the normal operation. Nonwoven fabric or insulation sheet is laid on the top of the film heater and the floor finishing materials such as reinforced floor are glued together.

In order to heat the film heater as described above, several stages of construction are required. Especially, the soldering or crimping terminal connection for a large number of film heater electrodes is performed in the field. Due to the frequent occurrence of defects, the on-site construction of the film heater is a general phenomenon, which is a factor that increases the construction cost.

In addition, the general film heater is produced in the form of a roll of several tens of meters in the same pattern, and the heating current can be extended in series because the allowable current capacity of the film heater electrode (the maximum allowable current of the general film heater electrode is about 10A) is limited. Since the length is limited, when the construction exceeds the allowable current capacity, overheating occurs in the film heater electrode, causing uneven heating or deteriorating the life of the film heater.

The present invention has been developed in order to solve the disadvantages of the conventional heating panel as described above and problems occurring during the heating construction of the film heater, prefabricated heating having a film heater, a heating element coupling member and a power connection unit integrally provided. By providing a mat, the heating mat can be easily and quickly assembled on the floor, wall, or ceiling of a building, without using separate electrode connecting wires or coupling members for heating construction. The purpose is to prevent a decrease in durability.

In addition, the present invention is to configure a double power circuit in all the heating mats assembled by assembling the rectangular power connector and the wire integrated power connector in the power connection portion formed in the four corners of the prefabricated heating mat, the entire heating mat without overload The power is uniformly supplied to the purpose to enable even heating.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a reference view showing a power connection configuration in a conventional film heater construction, Figure 2 is a plan view showing the external appearance of the prefabricated heating mat according to the present invention.

In the conventional film heater construction, as shown in FIG. 1, a 5 to 10 mm thick insulation is adhered to the floor of a building, and the film heater wound in a roll shape is cut to a length suitable for the construction area and the allowable current capacity, and several sheets are arranged side by side. By connecting the electrodes of the film heater to the connecting terminal, and are connected to the temperature controller wires 14a and b, and the film heater copper foil electrodes 12a and b having the same polarity on the front and rear surfaces of the film heater 11, respectively. It shows the process of power supply combined.

Recently, film heaters, which have been spotlighted as far-infrared radiant heating elements, are produced with 4 ~ 5 kinds of roll-shaped standard products according to the manufacturer, and the film heater size can be selected according to the width of the floor area when heating. The maximum allowable current of the heater electrode is about 10A). Cut the film heater to a length that fits and connect it with a connecting member. The general construction method is to solder a large number of film heaters in the field according to the heating area. Since there is a lot of partial connection parts, there is a problem that many connection defects occur at the connection part of the film heater after construction because it is fastened by the connection terminal and connected with each other.

Since the copper foil electrode of the power sheet is reinforced to the film heater electrode (the maximum allowable current is 10A) of the general standard, it is possible to supply a large amount of current to the heating mat. When assembling a heating mat in a large area, a large number of heating mats can be combined in series without an intermediate connection line to prevent overload, which shortens the construction time and is effective because there is no gap with the connection line.

In addition, even when the electrode of the film heater, which is the heating element of the heating mat, is partially disconnected by external impact after assembling and heating the heating mat, power is supplied through the lower power sheet electrode, so that stable heating is possible, and the film heater is the heating element. Heating mat can be manufactured by changing copper wire width and thickness of power sheet without changing specification, so it is possible to standardize by setting allowable current capacity and number of assembly for each use of heating mat.
