Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a hollow sheet connecting device that connects hollow sheets such as sheet-like floor heating panels in a continuous state, each of which has a flow path for flowing hot water therein. be.

[Background technology]

Generally, the connection of sheet-like floor heating panels is as follows:
As shown in FIG. 1, a connecting pipe 2 is attached vertically downward from the end face of a sheet-like floor heating panel 1, thereby connecting two sheet-like floor heating panels 1. However, when connecting in this way, the connecting pipe 2 protrudes downward, so a hole 3a is made in the floorboard 3 as shown in the figure, and the connecting pipe 2 is placed in the hole 3a. . However, when making the holes 3a in the floorboard 3 in this way, not only does it take a lot of time and effort, but also sheet-like flooring is required in places where the holes 3a cannot be made or where it is not desired to make the holes 3a in the floorboard 3. There was a problem in that the heating panel 1 could not be installed. In FIG. 1, 3b is a heat insulating material provided between the floorboard 3 and the sheet-like floor heating panel 1.

[Purpose of the invention]

An object of the present invention is to provide a hollow sheet connecting device that allows hollow sheets to be connected and connected without making holes in the floorboard.

[Disclosure of the invention]

This invention includes a first perforated ring disposed in a connecting hole of a first hollow sheet with its outer peripheral side pushed into the inner peripheral part of the connecting hole, and a second hollow sheet. A second perforated ring is disposed with its outer peripheral side pushed into the inner peripheral part of the connecting hole, and the collar is inserted into the connecting hole on the front side of the first hollow sheet. The first collared engagement tool is loosely inserted into the connecting hole with the collar positioned on the peripheral edge of the second hollow sheet, and the connecting hole is inserted into the connecting hole with the collar positioned on the peripheral edge of the connecting hole on the back side of the second hollow sheet. The first and second hollow sheets are stacked with their back sides and front sides facing each other by aligning their connecting holes, and then The gist thereof is a hollow sheet connecting device that connects the first and second hollow sheets in a state where they communicate through the connecting hole by engaging a second flange-equipped engaging member. .

In other words, by doing so, the hollow sheets can be interconnected without making holes in the flooring material.

FIG. 2 is an explanatory diagram showing the configuration of an embodiment of the present invention, and FIG. 3 is an enlarged perspective view of the embodiment of the invention. In these figures, numerals 4, 5, and 6 are first, second, and third sheet-like floor heating panels each having a flow path through which warm water flows. A connection hole is formed in the first sheet-like floor heating panel 4, and a connection hole corresponding to the connection hole is also provided in the second sheet-like floor heating panel 5. Further, the third sheet-like floor heating panel 6 is also provided with a connection hole, and the second sheet-like floor heating panel 5 is provided with a connection hole corresponding to the connection hole.
The first sheet-like floor heating panel 4 is connected to the connecting hole by a first perforated ring 7 having a large number of through holes on the outer peripheral surface as shown in FIG. It is placed in a pushed-in position. Also,
The connection hole of the second sheet-like floor heating panel 5 is also provided with a second perforated ring 8 having a large number of through holes on its outer circumferential surface as shown in FIG. It is arranged so as to be pushed into the inner peripheral edge of the connection hole of the panel 5. The connecting hole of the first sheet-like floor heating panel 4 is fitted with a flanged nut 9 (see FIG. 3) with the collar portion positioned on the periphery of the connecting hole on the front side of the sheet-like floor heating panel 4.
is loosely inserted into the connection hole of the second sheet-like floor heating panel 5, with the collar positioned on the periphery of the connection hole on the back side of the second sheet-like floor heating panel 5. It is threadedly engaged with a bolt with a collar 10 (see FIG. 3) to connect the first and second sheet-like floor heating panels 4 and 5 in communication. Similarly, the first and second perforated rings similar to those described above are also formed in the connection holes of the third sheet-like floor heating panel 6 and the corresponding connection holes of the second sheet-like floor heating panel 5. 7, 8, a flanged nut 9, and a flanged bolt 10 are arranged, whereby the third and second
The sheet-like floor heating panels 6 and 5 are connected. In this case, the first and second perforated rings 7, 8 act as spacers and are spaced between the flanges of the flanged nut 9 and flanged bolt 10 and their own upper or lower ends. The first (third) and second sheet-like floor heating panels 4, 6, and 5 are sealed by sandwiching the connecting hole peripheries on the front and back sides. That is, since the peripheral edge of the connecting hole of the sandwiched sheet-like floor heating panels 4, 6 acts as a sealing material, packing or the like is not necessary. Moreover, since the flanged bolt 10 and nut 9 are used instead of conventional bolts and nuts, the overall thickness is reduced. The flanges of the flanged nuts 9 that appear on the surface side of the first (third) sheet-like floor heating panels 4 and 6 are processed into a round head shape, and are designed to eliminate the discomfort when stepping on them with your feet. has been done.

In this configuration, as shown in FIG.
The hot water flowing through the internal flow path of the sheet-like floor heating panel 4 connects the first and second sheet-like floor heating panels 4 and 5 through the through holes provided in the first perforated ring 7. from there through the through hole in the second perforated ring 8 and into the second sheet-like floor heating panel 5. Then, it flows inside the second sheet-like floor heating panel 5 in the direction of the third sheet-like floor heating panel 6, and is provided in a connection hole that corresponds to a connection hole in the third sheet-like floor heating panel 6. It enters into the third sheet-like floor heating panel 6 through the first perforated ring 7 provided in the connection hole of the second perforated ring 8 and the third sheet-like floor heating panel 6.

In this way, the first, second, and third sheet-like floor heating panels 4, 5, and 6 are connected in communication by the connecting device, so that the hot water flowing inside the first sheet-like floor heating panel 4 → second sheet-like floor heating panel 5 → third sheet-like floor heating panel 6
It will flow along the path of In this case, instead of using conventional bolts and nuts, use bolts with flanges 1.
0. Since the first, second, and third sheet-like floor heating panels 4, 5, and 6 are connected using the nuts 9, it is possible to connect them with a thickness that is approximately twice the thickness of the sheet-like floor heating panels. becomes. Therefore, when installing it, as shown in FIG.
By removing an amount corresponding to the connecting portion, the connected sheet-like floor heating panels 4, 5, and 6 can be laid flat.
Further, there is no need to make holes in the floorboard 12.

〔Effect of the invention〕

Since the hollow sheet connecting device of the present invention is configured as described above, it is possible to connect hollow sheets such as sheet-like floor heating panels in a continuous state without drilling holes in the floorboard, and improves workability. It can be measured. Furthermore, it is now possible to install hollow sheets such as sheet-like floor heating panels in places where it was previously impossible to install holes in the floorboards. Moreover,
Since there is no need to drill holes in the floorboards, it can be installed in places where it is not desirable to drill holes.
