Abstract

PURPOSE:To adhere a heating panel directly to a concrete floor and facilitate connection between connecting terminal blocks by adhering a base plywood to the back side of a heating panel comprising a heating means on the back side of a surfacing material, and slidably containing a connecting terminal block for wiring in the base plywood. CONSTITUTION:A heat-equalizing plate 2a and a film heater 2b are provided as a heating means 2 in a recessed part 6 on the back side of a surfacing material 1 to construct an elongate heating panel 3. A base plywood 4 is adhered to the back side of the panel 3, and a containing recessed part 7 is provided at an end part with respect to the longitudinal direction of the base plywood 4. A terminal block mount plate 8 is contained in the recessed part 7, and a slide plate 15 of a connecting terminal block 5 is slidably inserted in slide grooves 14 provided in both side pieces 8c of the mount plate 8. A cable 10 for connection between floor heating panels A is led out from the terminal block 5 to the exterior. A cushioning material 11, such as a foamed product of polyethylene or natural rubber, is adhered to the back side of the base plywood 4. The floor heating panels can be adhered directly to a concrete floor 12, and leading-out and connection of the cables 10 at the time of working are facilitated.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to electric floor heating panels.

[Prior art]

2. Description of the Related Art Electric floor heating panels A' in which heating means are embedded in the back side of a rising surface material are conventionally known.

[Problem to be solved by the invention]

In the conventional electric floor heating panel A', as shown in FIG. Although it can be used on concrete floors, it cannot be applied directly to concrete floors in condominiums, etc., and floor heating has not been possible in condominiums. For this reason, the present inventor has already adhered the base plywood 4 to the back side of the heating panel 3, which has the heating means 2 on the back side of the surface material 1, as shown in Figure @S, and inside the base plywood 4. We have developed a floor heating panel A" that houses a connecting terminal block 5 for wiring fixed via a terminal block mounting plate 8. This floor heating panel A" can be attached directly to the concrete floor 12. This makes it possible to provide floor heating in apartments, etc. However, since the connecting terminal block 5 is fixed, it is possible to provide a margin for the electric wires 10 connecting the five connecting terminals as shown in FIG. However, there was a problem that the workability was slightly inferior. The present invention has been made in view of the above circumstances, and its purpose is to enable direct attachment to the concrete floor 12, to enable floor heating in apartments, etc., and to connect connecting terminal blocks. The object of the present invention is to provide a floor heating panel that is easy to install and has excellent workability.

[Means to solve problems]

In the floor heating panel of the present invention, a base plywood 4 is attached to the back side of a heating panel 3 in which a heating means 2 is provided on the back side of a surface material 1, and a connecting terminal block 5 for wiring is attached inside the base plywood 4. It is slidably housed, and this configuration solves the above problem. [Function] The wiring connection terminal block 5 is housed in the base plywood 4 attached to the back side of the heating panel 3 (therefore, the wiring connection terminal block 5 is placed on the back side of the floor heating panel A). It does not protrude and can be directly attached to concrete floors, making it possible to provide underfloor heating in apartments, etc. Moreover, since the connecting terminal blocks 5 are slidably accommodated, the connection between the connecting terminal blocks 5 is easy. [Example 1] A recess 6 is formed on the back surface of the surface material 1, and a heat equalizing plate 2a and a film heater 2b, which are the heating means 2, are installed in the recess 6.
are arranged to constitute a long heating panel 3. A base plywood 4 is adhered to the back side of the heating panel 3. A housing recess 7 is provided in the ra portion of the base plywood 4 in the longitudinal direction. A terminal block mounting plate 8 is accommodated in this accommodation recess 7 . The terminal block mounting plate 8 is of an inverted hat shape, and is screwed to the base plywood 4 at the lower piece 8a, and the connecting terminal block 5 is screwed to the base plywood 4 at the lower piece 8a, and the connecting terminal block 5 is inserted into the slide groove 14 formed in the lower side pieces 8c of both upper pieces 8b. The slide plate 15 is slidably inserted, and the connecting terminal block 5 is slidably accommodated in the accommodation recess 7. The terminal block mounting plate 8 is housed in the four housing parts 7 such that the connecting terminal blocks 5 are located on both sides of the heating panel 3 in the width direction. Connecting terminal blocks 5° to each other and film heater 2b
is connected to the connecting terminal block 5 through the connecting hole 9 of the terminal block mounting plate 8, and from the connecting terminal block 5 there is a V for connecting the floor heating panels A to each other.
An electric wire 10 such as a VF wire is led out. A plurality of grooves may be provided in the base plywood 4 from the back side to the front side, and mfr/A may be used as a soundproofing material. A cushioning material 11 such as polyethylene or natural rubber foam having a thickness of about 51 mm is adhered to the back surface of the base plywood 4. A plurality of floor heating panels A are installed by directly adhering them to a concrete floor 12, such as a concrete slab of a building, using an adhesive. During construction, as shown in Figure @4, the electric wires 10 of one floor heating panel A are pulled and the connecting terminal block 5 is slid toward the adjacent floor heating panel A to connect the electric wires 10. After this, the electric connector 11A10 is pressed and the connecting terminal block 5 is pushed in, thereby joining the floor heating panels A to each other and adhering them to the concrete floor 12. In this case, since the connecting terminal blocks 5 are provided on both sides of the floor heating panel A,
The electric wire #i10 can be pulled out from either the left or right side, and there is no need to worry about the direction in which the electric wire 10 is drawn out during construction. [Effects of the Invention] In the present invention, a base plywood is pasted on the back side of a heating panel in which a heating means is provided on the back side of the surface material, and a connection terminal block for wiring is slid into the base plywood. Because it is housed freely, the connecting terminal block for wiring does not protrude from the back side of the floor heating panel, and therefore it can be attached directly to concrete floors, making it possible to provide floor heating in apartments, etc. Moreover, since the connecting terminal blocks are slidably housed, the connection between the connecting terminal blocks is easy and the workability is excellent.
