Description

[Detailed description of the invention] The present invention relates to a heating floor panel, and more specifically, hot water pipes 2 arranged on the back side of a surface board 1 are fixed with pipe fixing tools 3. This relates to a floor panel for heating, in which a locking hook 4 is provided to project backward from the top, and a hot water pipe 2 and a locking hook 4 are buried in a heat insulating member 5 formed on the back surface of a top plate 1.

Conventionally, the heating floor panel C is as shown in Figs. 1 and 2, and a hot water pipe 2' is arranged in a meandering manner on the back side of a surface plate 1', and the straight part of this hot water pipe 2' is arranged in a meandering manner. 7' is fixed with a pipe fixing device 3' having an Ω-shaped cross section, and this hot water pipe 2' is inserted into a heat insulating member 5' formed by foaming on the back surface of the surface plate 1'. Since the member 5' is simply attached to the back surface of the surface plate 1' and the hot water pipe 2' is placed in contact with the surface plate 1', when hot water is passed through the hot water pipe 2', the hot water pipe There were disadvantages in that the heating floor panel C warped due to heat concentration at the portion 2', and in that when the heating floor panel C warped, the surface plate 1' was more likely to peel off than the heat insulating member 5'.

The present invention was devised in view of the drawbacks of the conventional example, and its purpose is to provide a heating floor panel that does not cause warping or separation of the surface plate and the heat insulating member.

The first embodiment of the present invention will be described below in Figures 3 and 4.
This will be explained in detail according to the diagram. The hot water pipe 2 is formed in a meandering manner, and has connecting portions 8 at both ends. The pipe fixing device 3 is a long one with L-shaped locking hooks 4 protruding from both sides of a main body 3a having an Ω-shaped cross section at a plurality of locations, and the hot water pipe 2 is arranged on the back surface of the surface plate 1. death,
The straight part 7 of the hot water pipe 2 is fitted into the main body part 3a of the pipe fixing tool 3 and fixed to the surface plate 1. Heat insulation member 5
is divided into a heat insulating board part 5a and a back plate 5b attached to the back surface of the heat insulating board part 5a, and the heat insulating board part 5a is made of a foaming agent such as foamed polyurethane resin. After fixing the hot water pipe 2 with a pipe fixing tool 3, a foaming agent is injected and foamed to form a heat insulating plate part 5a, and a locking hook 4 is installed inside the heat insulating plate part 5a.
and hot water pipe 2 are buried. Here, the locking hook 4 serves to fasten the top plate 1 to the heat insulating plate portion 5a. Two diagonal corners of the heat insulating member 5 and the surface plate 1 are cut off to form notches 9, from which the connecting portion 8 of the hot water pipe 2 protrudes. A large number of lever heating floor panels A are laid on the floor and the hot water pipes 2 are connected to each other, and then an auxiliary floor plate (not shown) is fitted into the notch 9 to form a heating floor. Next, hot water is flowed into the hot water pipe 2 to heat the floor surface. In this case, heat is conducted and diffused from the hot water pipe 2 to the pipe fixing device 3, and the entire surface of the surface plate 1 is evenly heated.

Next, a second embodiment of the heating floor panel B of the present invention will be described in detail with reference to FIGS. 5 and 6. In this case, the pipe fixing tool 3 has a flat plate shape, and has a large number of L-shaped locking hooks 4 protruding from appropriate places. It is fixed at At this time, as shown in FIG. 5, the tube fixing device 3 is attached to almost the entire surface of the surface plate 1.

As described above, the present invention consists of fixing the hot water pipes installed on the back side of the top plate with a pipe fixing tool, protruding from the pipe fixing tool to the back, and forming heat insulation on the back side of the top plate. Since hot water pipes and locking hooks are embedded within the component, hot water is passed through the hot water pipes, heat accumulates around the hot water pipes of the heating panel, and the surface plate that is close to the hot water pipes is heated locally. Even if the top plate tries to expand or contract locally due to heating, the locking hook embedded in the heat insulating member acts as an anchor, resisting the local expansion or contraction of the top plate, and prevents the top plate from warping. Furthermore, due to the local expansion and contraction of the surface plate, a force is applied to separate the surface plate and the heat insulating member, but as above, the locking hooks firmly adhere to the heat insulating member and serve as an anchor. It is possible to prevent the surface plate from peeling off from the heat insulating member, and since the locking hook is buried within the heat insulating member, the locking hook does not protrude outside, preventing heat bridges and improving heating efficiency. can be increased. That is, in the present invention, by embedding the locking hook protruding from the pipe fixing device in the heat insulating member, the anchor effect of the locking hook prevents local expansion and contraction of the surface plate and separation from the heat insulating member. At the same time, heat bridging due to the locking hook can be prevented and heating efficiency can be increased.
