Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor heating panel, and more particularly, to a floor heating panel laid between supplementary joists arranged on a rough floor at regular intervals.

[0002]

[Prior art]

 The floor heating construction method using wood flooring is as follows: (1) A large rectangular or rectangular sheet heating panel with integrated hot water pipe and heat insulating material is laid on a rough floor, and (2) Floor heating in which a wooden flooring material is adhered to the surface with a glue. (2) A groove for embedding a hot water pipe is provided in a rectangular or rectangular plywood board, and a radiator plate is placed on the top surface to mark the position of the hot water pipe. The panel is laid on the rough floor, and the wooden flooring material is nailed and fixed on the heat sink at a position other than the marking position. (3) Auxiliary joists are arranged at regular intervals on the rough floor, and the space between the auxiliary joists For example, a rectangular floor heating panel having a hot water pipe embedded therein is laid, and a wood flooring is laid on the floor heating panel with an auxiliary joist as a supporting member.

The construction method of (1) has an advantage that it can be easily constructed on a rough floor or a floor currently used, but since it is mainly made of resin, it cannot bear the load, and the floor heating panel expands and contracts. Since the above process is repeated, the adhesive is peeled off, which causes a squeaking noise and a sliding noise between the floor heating panel and the wood flooring material. The method (2) has an advantage that the construction is easy, but the expansion and contraction of the heat dissipation plate easily causes noise due to creaking and sliding with the wooden flooring material, and loosening of the fixed nail occurs. In addition, there is a large temperature difference between the inlet side and the outlet side of the hot water pipe, which causes a large difference in floor temperature and is not suitable for large buildings.

Since the construction method of (3) uses the auxiliary joist 20 as shown in FIGS. 7 to 10, the connecting pipe 50 connecting the hot water pipes 40 of the floor heating panel 30 between the auxiliary joists 20 is As shown in FIGS. 7 and 9, the lower part of the auxiliary joist 20 is diverted, or as shown in FIGS. 8 and 10, a part of the auxiliary joist 20 must be cut out to allow connection pipes. The connection work of 50 requires labor and low construction efficiency, and the connection pipe 50 needs to have a special shape such as a V-shape or a U-shape, which increases the cost. Moreover, since the hot water supply port 45 and the hot water return port 46 are separated, a temperature difference occurs between the floor heating panel 30 on the hot water supply port 45 side and the hot water return port 46 side.

Further, since the auxiliary joist 20 is interposed between the floor heating panels 30, the surface of the wood flooring material on the auxiliary joist 20 has a low temperature. Therefore, as shown in FIGS. 9 and 10, a long aluminum sheet (tape) 60 is adhered and fixed on the auxiliary joist 20 with an adhesive, and the long side edges of the aluminum sheet 60 are adjacent to the floor heating panel. The heat radiation plates 31 and 31 of 30 and 30 are brought into contact with each other with an adhesive. In this method, nails are used to fix the auxiliary joists and the wooden flooring material. When a nail and an adhesive are used, the adhesive is peeled off due to expansion and contraction of the heat dissipation plate 31, and a sliding noise and a squeaking noise are generated between the wood flooring material, the aluminum sheet 60 and the heat dissipation plate 31.

[Problems to be solved by the device]

 Therefore, the present invention provides a floor heating panel in the construction method of the above (3), which simplifies the connection work of the hot water pipe 40 of the floor heating panel 30 to improve the construction efficiency and further does not require the connection pipe 50. The purpose is to do.

[0007]

[Means for Solving the Problems]

 A floor heating panel according to the present invention is a floor heating panel which is laid between a plurality of auxiliary joists on a rough floor and arranged at fixed intervals, and which connects hot water pipes fixed to a heat radiating plate. In the above, the floor heating panel is composed of a rectangular shape body, a substantially L-shape body, or a substantially U-shape body which extends between the auxiliary joists at an end portion of the auxiliary joists and is laid on the rough floor. The floor heating panel is characterized by a pair of hot water pipes arranged so that their ends are exposed on the rough floor between the auxiliary joists.

[0008]

[Function] When a floor heating panel having a rectangular shape, a substantially L shape, or a substantially U shape extends between the auxiliary joists at the end of the auxiliary joists and is laid on the rough floor, a hot water pipe Face each other, and therefore, the hot water pipes of each floor heating panel can be connected on the rough floor by silver brazing or the like without connecting pipes.

[0009]

【Example】

 The present invention will be described below based on the illustrated embodiment. As shown in FIG. 1 (A), auxiliary joists 2 are laid at regular intervals on a rough floor 1 of a predetermined room such as a square, and a floor heating panel 3 is fitted and interposed between the auxiliary joists 2. . In the floor heating panel 3, a pair of hot water pipes 4 forming a reciprocating path for hot water supply are embedded in parallel. Reference numerals 5 and 6 are hot water supply ports or return hot water ports connected to the boiler.

The floor heating panel 3 includes a straight rectangular shaped body 3a, and three types of special shapes connected to the straight shaped rectangular body 3a, a substantially L-shaped body 3b and a substantially U-shaped body 3c. 3a has a distinction between long and short. The substantially L-shaped body 3b and the substantially U-shaped body 3c have a cutout portion 2a formed in the auxiliary joist 2 and have a portion extending between the auxiliary joists 2, and the auxiliary joist 2 is placed on the rough bed 1 at that portion. Not laid.

The substantially L-shaped body 3 b and the substantially U-shaped body 3 c also serve as the above-mentioned conventional connecting pipe for connecting the hot water pipe 4 of the floor heating panel 3 between the auxiliary joists 2, and An end 4a of the hot water pipe 4 is exposed at each continuous end between the joists 2, and they are faced to face each other, and are brazed to form a connection 7 between the ends 4a and 4a. Has been formed. Further, as shown in FIG. 4, the floor heating panel 3 has a structure in which a section U-shaped groove 9 is engraved in a skeleton 8 such as plywood or a heat insulating material, and the groove 9 is fixed to a radiator plate 10. The hot water pipe 4 is embedded, and the heat dissipation plate 10 is attached to the upper surface of the body 8.

As shown in FIG. 5, the arrangement of the hot water pipes 4 in the rectangular shaped body 3a is a pair of hot water pipes 4, 4 as shown in FIG. It may have a hook-shaped arrangement as shown in B) or a branched arrangement as shown in (C). As shown in FIG. 1 (B), the one shown in FIGS. 5 (A) and 5 (B) is laid between the auxiliary joists 2 similarly to the substantially L-shaped body 3b and the substantially U-shaped body 3c. It can be used as floor heating panels 3d and 3e which also serve as connecting pipes for the rectangular shaped body 3a. The one shown in (C) can be used when the floor heating panel 3 is installed in another room or corridor.

Therefore, when the floor heating panel 3 is laid between the auxiliary joists 2 on the rough floor 1 as shown in FIG. 1A, for example, each hot water supply pipe of the rectangular shaped body 3a and the substantially L-shaped body 3b The connection connection of 4 can be made in the same plane as the floor heating panel 3 on the rough floor 1 by abutting the end 4a of the hot water pipe 4 exposed at the end of the continuous connection and brazing. Since it is not necessary to pass the connecting pipe through the lower part of the auxiliary joist 2 as in the past, the work is extremely simplified and the construction efficiency is improved.

When the hot water pipes 4 of each floor heating panel 3 are connected and the laying of the floor heating panel 3 is completed, as shown in FIG. 2 and FIG. 3 (A), aluminum is placed on the auxiliary joist 2. A heat transfer plate 11 made of a tape (sheet) is laid with an adhesive 12, and the longitudinal end portion of the heat transfer plate 11 is extended above the heat dissipation plate 10. The heat dissipation plate 10 and the heat transfer plate 11 have the same thickness of the auxiliary joist 2 and the floor heating panel 3, so that the heat dissipation plate 10 and the heat transfer plate 11 are in contact with each other, so that the heat dissipation plate 10 to the heat transfer plate 11 is contacted. Heat is transferred. The heat radiating plate 10 and the heat transfer plate 11 are not bonded by an adhesive.

As shown in FIG. 6, the heat transfer plate 11 is formed by forming through holes 13 at a predetermined interval in an elongated aluminum plate having substantially the same length as the auxiliary joist 2 and wider than its width dimension. As shown in FIGS. 6 (B) and 6 (C), a double-sided adhesive tape 12 is attached to the back surface. As shown in FIGS. 3 (A) and 3 (B), the through hole 13 is provided so that the adhesive 15 can be used between the wooden flooring material 14 and the auxiliary joist 2. A nail 16 for fixing the wooden flooring material 14 to the auxiliary joist 2 penetrates through the through hole 13.

As for the double-sided adhesive tape 12, as shown in FIG. 6B, two strips are attached to the left and right of the through hole 12 in the longitudinal direction, or the double-sided adhesive tape 12 is attached to the central portion surrounding the through hole 12 in the longitudinal direction. Is good. In addition, without attaching the double-sided adhesive tape 12 to the heat transfer plate 11, the double-sided adhesive tape 12 is attached to the upper surface of the auxiliary joist 2 in the same manner as described above, and the heat transfer plate 11 is placed and fixed by adhesion. . Even if the adhesive 15 is applied between the wooden flooring material and the auxiliary joist 2 in the through hole 13, the adhesive 15 remains on the through hole 13 or the heat transfer plate 11, regardless of the heat radiating plate 10. The adhesive is adhered and fixed by the wooden flooring material 14, the auxiliary joist 2 and the heat transfer plate 11, and the adhesive 15 is not peeled off due to expansion and contraction of the floor heating panel 3.

[Effect of device]

 According to the present invention described above, a floor heating panel having a special shape is formed to extend between the auxiliary joists at the ends of the auxiliary joists and is laid on a rough floor, and a pair of hot water is passed through the floor heating panels. Since the pipes were arranged in parallel and the end of the hot water pipe was exposed on the rough floor between the auxiliary joists, connection work by silver brazing etc. of the hot water pipe was possible on the rough floor, and floor heating was possible. Improve the construction efficiency of panel laying work.

Further, since a pair of parallel hot water pipes are embedded in the floor heating panel, the hot water supply port and the return hot water port can be connected to the same floor heating panel, and moreover, the hot water supply and the hot water return to each floor heating panel are possible. Since hot water is passed through, the difference in temperature between the floor heating panel near the hot water supply port and the part far from the hot water supply port is reduced. Since the temperature difference is small, the hot water supply temperature can be set low.

Since the wood flooring material used for floor heating responds to deterioration due to high temperature, a wood flooring material dedicated to floor heating is used. According to this invention, it can be used at a low temperature of hot water supply. It is possible to use general wood flooring materials that are not exclusively used for heating.

Further, since the floor heating panel can fix the wooden flooring material by using nails and an adhesive together, it prevents floor squeal and enables reliable construction using ordinary floor construction methods and conventional construction methods.
