Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a header for a floor heating panel connected to a heat radiating pipe laid on a panel body, and a header connection portion thereof.

[0002]

2. Description of the Related Art In a conventional floor heating panel, headers (distribution fittings) are respectively connected to an inlet and a return of a radiator tube through which a heat medium flows, and the radiator tube is connected to a heat medium supply source and the like via the header. Connected to the connecting pipe. And
A connection portion cover made of the same heat insulating material as the panel body of the floor heating panel is laid on the connection portion side of the header so that the heat insulating state of the portion is not impaired.
Note that a semi-rigid or rigid foam of a thermoplastic resin such as expanded polystyrene or expanded polypropylene is generally used as the panel body.

[0003]

The connection portion cover is cut into the lower surface so that the connection portion cover can be laid flush with the panel body side while avoiding interference with a header, a connecting pipe or the like. Recess (escape) is provided. Since this recess is provided considerably deeply in connection with the heat radiation tube, a reduction in the strength of the connection portion cover itself is inevitable,
In addition, there is a problem that it takes time and effort to provide the recess deeply according to the state of the connection portion.

The first object of the present invention is to solve such a problem. The first object of the present invention is to improve the connection work with the connecting pipe so that the connecting portion cover does not need to be provided with a recess. Another object of the present invention is to provide a header for a floor heating panel in which the header for a floor heating panel is used.

[0005]

First, the first aspect of the present invention is described.
In order to achieve the object of the present invention, a floor heating panel header characterized by the present invention comprises a horizontal pipe section having both ends closed, and protruding from a lower surface side of the horizontal pipe section in communication with the horizontal pipe body. The vertical pipe part is formed in a substantially T-shape, and the horizontal pipe part and the vertical pipe part are provided with connection port pipes facing in opposite directions. And, in the connection port pipe of the above-mentioned vertical pipe section, as it is convenient for connection work with the connecting pipe,
It is preferable that a flange for retaining the connection tool is provided.

In order to achieve the second object of the present invention, a header connecting portion of a floor heating panel, which is a feature of the present invention, comprises a horizontal pipe portion having both ends closed, and a horizontal pipe portion. And a vertical pipe portion projecting from the lower surface side of the horizontal pipe portion so as to communicate with the horizontal pipe portion. The header and the heat radiating pipe are laid on the panel main body, and a coating material is applied on the upper surface side, and at least a part of the vertical pipe part of the header is provided on the side surface of the panel main body. A floor heating panel provided with a concave portion in which the horizontal pipe portion can be mounted flush with the side surface portion of the panel main body, a header is mounted in the concave portion, and a connection port pipe of the horizontal pipe portion is provided. Has a configuration in which the radiator tube is connected.

[0007] According to the above configuration, since the vertical pipe portion is provided on the header, the connection work with the communication pipe can be easily performed by positioning the connection port pipe of the vertical pipe section below the lower surface of the panel body. . The header can be mounted on the side surface of the panel main body so that the recess provided on the side surface of the panel main body does not hinder the installation of the connection portion cover.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. First, the header according to the first and second aspects of the present invention will be described with reference to FIG. 1. Reference numeral 1 denotes a horizontal pipe section having both ends 1a closed, and 2 denotes a horizontal pipe section which communicates with the inside of the horizontal pipe section 1. A vertical tube portion protruding from the lower surface side of the portion 1 and has a substantially T shape as a whole. Usually, a plurality of horizontal tubes 1 (two in the illustrated case)
) And the vertical pipe part 2 is provided with one connection port pipe 4 facing in opposite directions.

The connection ports 3 and 4 are provided on their outer peripheral surfaces in a circumferential direction so that the connection with plastic pipes (radiator pipes and connecting pipes) connected to the connection port pipes 3 and 4 becomes strong. A plurality of notches 3a and 4a are provided along the respective lines to form a header. In addition, it is preferable that the connection port pipe 4 of the vertical pipe section 2 be provided with a flange 4b for holding a connection tool, which is located on the base side of the connection port pipe 4; One holding portion of the connection tool can be hooked on the flange 4b, which is convenient for performing connection work.

Next, the connecting part of the floor heating panel according to the third aspect of the present invention using the header having the above structure will be described with reference to FIGS. 2 and 3. Reference numeral 5 denotes a heat insulating panel body made of synthetic resin foam. , 6 are radiating pipes (two pipes are shown by phantom lines in the drawing) laid on the panel body 5 through the pipe grooves 7, and a coating material 8 such as aluminum foil is provided on the upper surface side thereof. Is attached. Side part 5a of panel body 5
Is provided with a pair of recesses 9a and 9b in which at least a part of the vertical tube portion 2 of the header and the horizontal tube portion 1 can be mounted flush with the side surface portion 5a of the panel body 5.

After the headers are mounted in the recesses 9a and 9b, respectively, the radiator tubes 6 are connected to their connection port tubes 3.
Are connected to the entrance side and the return side (both are not shown) to form a connection portion of the floor heating panel. In this connection part, after connecting the connecting pipe 11 to the connection port pipe 4 in the same manner as the conventional connection part, the connection part cover 12 is laid so as to abut the side part 5a of the panel body 5. The connection with the connecting pipe 11 is made below the lower surface of the panel body 5 by the connecting port pipe 4.
Can be performed.

The connecting portion cover 12 is formed of the same heat insulating material as the panel body 5, and even if the connecting portion cover 12 is foldably connected to the panel body 5,
It may be separated. When the connection cover 12 is foldably connected as shown in FIG.
The extended edge piece 8a functions as a hinge portion. Depending on the mounting state of the header, a recess for the escape of the connection port tube 4 may be provided shallowly on the lower surface of the connection portion cover 12.

[0013]

The present invention is as described above, and the connecting pipes to which the connecting pipes are connected are provided on the vertical pipes projecting from the lower surface of the horizontal pipes. Of course, it is not necessary to provide a cutout in the connection portion cover laid on the connection portion side, and this is extremely effective in maintaining the strength of the connection portion cover and protecting the header connection portion. .
