Description
Technical Field
[0001] This utility model relates to the field of underfloor heating installation technology, and more specifically, to an easy-to-install thin, integrated polyurethane noise-reducing and heat-insulating underfloor heating board. Background Technology
[0002] Underfloor heating systems, as a comfortable and energy-efficient heating method, are widely used in various types of buildings. Traditional underfloor heating construction typically involves laying multiple layers of materials, including insulation, reflective, fixing, and pipe layers. This process is complex, time-consuming, and suffers from problems such as significant heat loss and noise transmission. Common insulation boards have limited insulation performance, and pipe fixing often relies on external clips or straps, which can easily damage the insulation layer and affect the overall insulation effect. Furthermore, traditional underfloor heating boards are simply spliced together, resulting in loose connections between boards, which can easily create thermal bridging and heat leakage, reducing system energy efficiency.
[0003] Although there have been attempts at integrated underfloor heating panels in the existing technology, there are still problems such as insecure pipe fixing, complicated installation, and poor treatment of panel joints.
[0004] Therefore, it is necessary to improve existing technologies. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, a thin, integrated polyurethane noise-reducing and heat-insulating floor heating board with reasonable structure, convenient construction, excellent thermal insulation and noise reduction performance, and reliable connection is provided.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An easy-to-install thin integrated polyurethane noise reduction and heat insulation floor heating board includes a board body and positioning protrusions located on the board body. The positioning protrusions are evenly arranged in multiple rows along a 45° direction, and four adjacent positioning protrusions are distributed in a rhombus shape. The positioning protrusion is a cylindrical structure with a chamfer at the upper end and an arc groove I at the lower end. An arc groove II is provided on the plate body. The radius of the arc groove I is the same as the radius of the arc groove II. The arc groove I and the arc groove II cooperate to form a positioning groove for accommodating the underfloor heating pipe. The board body is a polyurethane integrated foam board, and a heat insulation film is provided on the lower surface of the board body.
[0007] Preferably, the positioning protrusion includes a fixed rod and a positioning sleeve rotatably mounted on the fixed rod. The fixed rod is integrally formed with the plate body. An axial limiting rod is fixedly connected to one side of the fixed rod. The lower end of the positioning sleeve is provided with an installation hole that mates with the fixed rod. One side of the installation hole is provided with a side hole that mates with the axial limiting rod. The upper end of the installation hole is provided with a circular groove that mates with the axial limiting rod. The diameter of the circular groove is larger than the diameter of the installation hole.
[0008] Preferably, the positioning sleeve has a cross-section on one side, and the cross-section is on the same elevation as the quadrant point on the side of the arc groove I.
[0009] Preferably, a groove is provided in the middle of two adjacent sides of the plate body, and a protrusion that cooperates with the groove is provided in the middle of the other two sides of the plate body. One of the protrusions has the same length as the corresponding side of the plate body, and the other protrusion has a length ≤ the length of the corresponding side of the plate body minus the groove depth.
[0010] Preferably, two adjacent sides of the plate body are provided with protrusions, and two other adjacent sides of the plate body are provided with recesses that mate with the protrusions. The protrusions and recesses are inserted into each other, and semi-cylinders that mate with each other are provided on the protrusions and recesses. The two semi-cylinders form a positioning rod, and a positioning sleeve is fitted on the upper end of the positioning rod.
[0011] Preferably, the chamfer is a rounded chamfer.
[0012] Preferably, the heat insulation film is integrally formed with the board body.
[0013] The advantages of this utility model compared with the prior art are as follows: 1. The panel body is made of polyurethane integrated foam molding, which has an extremely low thermal conductivity, effectively blocking heat transfer downwards and improving the thermal efficiency of the underfloor heating system; at the same time, polyurethane material has good sound absorption properties, which can reduce the transmission of impact noise from the floor slab. Integrated polyurethane underfloor heating panels reduce the thickness of the overall floor insulation layer, increase the usable indoor height, and the integrated heat transfer and sound transmission coefficients are consistent, which greatly improves noise reduction and heat preservation effects.
[0014] 2. The positioning protrusions are arranged at 45° and distributed in a diamond shape, forming a stable pipe positioning groove together with the arc groove on the board body, ensuring that the underfloor heating pipes are laid neatly and with consistent spacing; the upper end of the positioning protrusion is provided with a rounded chamfer to facilitate the smooth insertion of the pipe and reduce installation resistance.
[0015] 3. Grooves and convex strips are provided on the sides of the sheet body to prevent gaps between adjacent sheet bodies. The dimensional fit between the grooves and convex strips ensures that there are no hollow parts after the sheet bodies are spliced, and the thermal conductivity and noise reduction performance are consistent throughout. At the same time, the mechanical strength and sealing of the connection between the sheets are enhanced by the interlocking of the protrusions and concave holes, and the use of semi-cylinders and positioning sleeves for locking, effectively reducing thermal bridging and heat leakage.
[0016] 4. The positioning protrusion adopts a combination structure of a fixed rod and a rotatable positioning sleeve. The floor heating pipe can be quickly locked or released by rotation, which not only avoids damage to the positioning structure during installation, but also further improves the reliability of pipe fixation.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1: like Figures 1 to 6 As shown, an easy-to-install thin integrated polyurethane noise-reducing and heat-insulating floor heating board includes a board body 1 and positioning protrusions 2 located on the board body 1. The board body 1 can be square or rectangular, and the entire floor can be laid by splicing multiple board bodies 1.
[0022] The positioning protrusion 2 is used to limit the underfloor heating pipe. The positioning protrusion 2 is evenly arranged in multiple rows along the 45° direction on the plate body 1, and four adjacent positioning protrusions 2 are distributed in a diamond shape.
[0023] The positioning protrusion 2 is a cylindrical structure, and a chamfer 21 is provided at the upper end of the positioning protrusion 2. Preferably, the chamfer 21 is a rounded chamfer to facilitate the insertion of the underfloor heating pipe. An arc groove I 22 is provided at the lower end of the positioning protrusion 2, and an arc groove II 11 is provided on the plate body 1. The radius of the arc groove I 22 is the same as the radius of the arc groove II 11. The arc groove II 11 and the arc grooves I 22 on the left and right sides cooperate to form a positioning groove for accommodating the underfloor heating pipe.
[0024] Preferably, the board body 1 is an integrated polyurethane foam board, and a heat insulation film 3 is provided on the lower surface of the board body 1. The heat insulation film 3 is integrally formed with the board body 1.
[0025] To ensure the connection between adjacent plate bodies 1 and to reduce heat leakage, a groove 12 is provided in the middle of two adjacent sides of the plate body 1, and a protrusion 13 that cooperates with the groove 12 is provided in the middle of the other two sides of the plate body 1. One of the protrusions 13 has the same length as the corresponding side of the plate body 1, and the other protrusion 13 has a length equal to or slightly less than the corresponding side of the plate body 1 minus the depth of the groove 12. Preferably, the length of the other protrusion 13 is equal to the corresponding side of the plate body 1 minus the depth of the groove 12, so that the material thickness is the same everywhere after the adjacent plate bodies 1 are connected.
[0026] To ensure the reliability of the connection between adjacent plate bodies 1, two adjacent sides of the plate body 1 are provided with protrusions 14, and the other two adjacent sides of the plate body 1 are provided with recesses 15 that cooperate with the protrusions 14. The protrusions 14 and recesses 15 are inserted into each other. The protrusions 14 and recesses 15 are provided with mutually cooperating semi-cylinders 16. The two semi-cylinders 16 form a positioning rod. The upper end of the positioning rod is fitted with a positioning sleeve 24. The positioning sleeve 24 locks the two semi-cylinders 16, thereby locking the adjacent plate bodies 1.
[0027] Example 2: like Figures 7 to 9 As shown, in order to reduce the impact of the underfloor heating pipe installation on the positioning protrusion 2 and further ensure the fixing effect of the underfloor heating pipe, based on embodiment 1, the positioning protrusion 2 includes a fixing rod 23 and a positioning sleeve 24 rotatably set on the fixing rod 23. By rotating the positioning sleeve 24, the underfloor heating pipe can be locked and unlocked.
[0028] Specifically, the fixing rod 23 is integrally formed with the plate body 1. An axial limiting rod 29 is fixedly connected to one side of the fixing rod 23. The lower end of the positioning sleeve 24 is provided with a mounting hole 25. The positioning sleeve 24 is sleeved on the fixing rod 23 through the mounting hole 25. A side hole 26 is provided on one side of the mounting hole 25 to cooperate with the axial limiting rod 29. A circular groove 27 is provided at the upper end of the mounting hole 25 to cooperate with the axial limiting rod 29. The diameter of the circular groove 27 is larger than the diameter of the mounting hole 25. During installation, the axial limiting rod 29 enters the circular groove 27 through the side hole 26. By rotating the positioning sleeve 24 at a certain angle, the axial limiting rod 29 interferes with the lower end of the circular groove 27, thereby achieving axial limiting.
[0029] The positioning sleeve 24 has a cross-section 28 on one side, and the cross-section 28 is on the same plane as the quadrant point on the side of the arc groove I 22. In the initial state, the cross-section 28 is located on the side facing the arc groove II 11. At this time, the underfloor heating pipe can enter the positioning groove without resistance and will not exert lateral force on the positioning sleeve 24. After the underfloor heating pipe is installed in place, the positioning sleeve 24 is rotated so that the upper side of the positioning sleeve 24 limits the underfloor heating pipe.
[0030] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
