further, support comprises that two relative sides by gripper shoe extend upward respectively two side plates that form and the connecting plate that connects the upper end of two side plates.
preferably, the longitudinal section of the connecting plate of the support of plastics heat conduction frame is arc.
further, support is to comprise that longitudinal section is the arch support that string is positioned at the arc of below, and arch support thereunder has an opening corresponding to the position of the string on arc section, and gripper shoe covers on this opening.
preferably, plastics heat conduction frame also comprises two radiating wings that the width along the winding displacement groove stretches out and forms from the winding displacement notch by gripper shoe.Radiating wing can be played a supporting role on the one hand, also heat can be transmitted further to the floor of groove both sides on the other hand.
preferably, the longitudinal section of winding displacement groove is arc or rectangle.The set-up mode of winding displacement groove can be adjusted according to processing mode, as long as easy to process, be applicable to the placement of heat conduction frame and the layout of Electrothermic wire and get final product.
more preferably, the winding displacement groove is two or more, and two or more winding displacement grooves are arranged along the width of plate.The number of winding displacement groove can be adjusted according to width and the thickness of plate, can reach good heat transfer effect and get final product on the basis that guarantees floor intensity.
preferably, in the winding displacement groove, Electrothermic wire is positioned on a top of the trellis of plastics heat conduction frame.More preferably, the height of support is approximately 1/2 of groove depth, and like this, Electrothermic wire is positioned on a top of the trellis and namely substantially is positioned at the middle position of groove, and heat distributes more even.
compared with prior art, the present invention has following advantages: the invention provides a kind of heating floor, offer the winding displacement groove on the bottom on this floor, be provided with Electrothermic wire and plastics heat conduction frame in the winding displacement groove, this kind of plastics heat conduction frame made by high temperature resistant PPR material, has good heat transmission and processing characteristics, and intensity is large, good toughness, safety and environmental protection.Heating floor processing of the present invention is easy, and heating is fast.Plastics heat conduction frame is better than metal material electrical insulation capability, thereby safer.PPR plastics heat conduction frame high-strength light with arch support and radiating wing, good toughness can play reinforcement effect to the intensity on floor when the heat rapidly Electrothermic wire sent passes to floor, and environmental protection more.

The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention are easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made and more removed clear and definite defining.
consult accompanying drawing, heating floor of the present invention, offer along its length at least one winding displacement groove on bottom, be furnished with Electrothermic wire at least one winding displacement groove, Electrothermic wire passes the winding displacement groove and is electrically connected with power supply, in at least one winding displacement groove also the length direction along groove be provided with plastics heat conduction frame, plastics heat conduction frame conducts to floor for the heat that Electrothermic wire is sent, plastics heat conduction frame comprises gripper shoe and is arranged on the support on gripper shoe, support and gripper shoe form the hollow cavity of both ends open, support snaps in the winding displacement groove, and the space that existence can be placed Electrothermic wire between support and cell wall, gripper shoe be positioned at the winding displacement groove to lower opening and seal this opening, Electrothermic wire is positioned at space or is arranged in the hollow cavity of plastics heat conduction frame.
particularly, consult Fig. 1-Fig. 2, heating floor according to first embodiment of the invention, it comprises flaggy, and intermediate layer and lower flaggy offer two winding displacement grooves 1 in the bottom of plate, two winding displacement grooves 1 are arranged along the width of plate, the number of groove is according to integral width and the thickness setting of plate, plate is wider need to arrange a plurality of winding displacement grooves by the heat Transmit evenly to plate, a plurality of winding displacement grooves preferably evenly are spaced apart and arranged in the plate bottom.Be furnished with Electrothermic wire 2 in winding displacement groove 1, Electrothermic wire 2 passes winding displacement groove 1 and is electrically connected with power supply, to generate heat after energising and heat dispersed to surrounding, in winding displacement groove 1 also the length direction along groove be provided with plastics heat conduction frame, plastics heat conduction frame 3 comprises gripper shoe 31 and is arranged on the support 32 on gripper shoe 31, support 32 and gripper shoe 31 form the hollow cavity of both ends open, and support 32 comprises that two relative sides by gripper shoe 31 extend upward respectively two side plates that form and the connecting plate that connects the upper end of two side plates.The longitudinal section of connecting plate is arc.Support 32 snaps in winding displacement groove 1, two side plates contact with two sidewalls corresponding in the winding displacement groove respectively, gripper shoe 31 be positioned at winding displacement groove 1 to lower opening and seal this opening, have the space can place Electrothermic wire 2 between support 32 and cell wall, Electrothermic wire 2 is positioned at space.Fig. 2 has showed the structure of the plastics heat conduction frame 3 of the present embodiment.
