Description

Technical Field

[0001] This utility model relates to the field of floor heating structure technology, specifically an elevated floor heating structure. Background Technology

[0002] Underfloor heating uses hot water at a temperature not exceeding 60℃ as a heat source, circulating within a coil system buried under the floor to heat the entire floor and radiate heat evenly into the room. Currently, underfloor heating systems require laying the heating coil system on the floor and then backfilling it with concrete or cement. This type of underfloor heating system has a long construction period, high construction costs, and is inconvenient for later maintenance.

[0003] The utility model application with application number 201721366139.3 discloses a modular quick-installation heating floor structure, including a structural base layer and a decorative layer on the structural base layer. Between the structural base layer and the decorative layer, from top to bottom, are a heat dissipation layer, a floor heating layer, and a raised layer. A pipeline system is laid in the raised layer. The raised layer includes a wooden joist frame located between the floor heating layer and the structural base layer, and height-adjustable footing components. The wooden joist frame is located at the angle between the structural base layer and the wall. The floor heating layer includes several separate floor heating modules and heating pipes laid on the floor heating modules. The floor heating modules are separated by footing components to form gaps, which are filled with expanding foam. The upper surface of the floor heating modules has serpentine floor heating grooves for laying heating pipes. It has the advantages of quick installation, short installation time, and high installation efficiency.

[0004] In existing elevated floor heating structures, self-tapping screws are typically used to fix the support plate modules to the keel frame during installation. However, when the support plate modules are disassembled and replaced, the self-tapping screws used to fix the support plate modules will be drilled into the same screw hole. This can easily cause the self-tapping screws to strip, resulting in unstable fixation of the support plate modules. If the drilling position of the self-tapping screws is changed every time the support plate modules are disassembled and replaced, there will be too many screw holes on the keel frame, which will affect the strength of the keel frame.

[0022] 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.

[0023] Example: Figure 1-8 As shown, this utility model provides an elevated floor heating structure, including a frame 1, a support plate module 2, a thermal insulation board 3, a reflective film 4, and a mounting plate 5. The support plate module 2 is detachably mounted on the frame 1. Positioning rods 9 are fixedly installed at the four corners of the lower surface of the support plate module 2. The upper surface of the frame 1 has multiple positioning slots 101 arranged in an array, and the positioning rods 9 can be inserted into the corresponding positioning slots 101. Each of the four positioning rods 9 is equipped with a limit component 10, and each of the four limit components 10 includes a lead screw 1001, which is rotatably mounted on the corresponding positioning slot. Inside the rod 9, the lead screw 1001 is inserted through and inserted into the support plate module 2. Each of the four positioning rods 9 has a slider 1002 slidably installed inside, and the lead screw 1001 is threaded into the corresponding slider 1002. A gear 1005 is fixedly installed at the bottom end of each of the four lead screws 1001. Two mirror-distributed toothed rods 1003 are slidably installed inside each of the four positioning rods 9, and the toothed rods 1003 mesh with the corresponding gears 1005. Multiple positioning slots 101 each have two mirror-distributed limiting slots 102, and one end of the toothed rod 1003 can be inserted into the corresponding limiting slot 102. The four lead screws 1001... The top of each of the 001 components is fixedly equipped with an internal hexagonal knob 1004. The elevated floor heating structure consists of a keel frame 1, multiple support plate modules 2, thermal insulation boards 3, reflective film 4, and mounting plates 5. During installation, firstly, using a level or similar tool, the keel frame 1 is elevated and installed on the wall of the room using expansion bolts. Next, the support plate modules 2 are installed on the keel frame 1, so that the positioning rods 9 on the support plate modules 2 are inserted into the corresponding positioning slots 101 on the keel frame 1. Then, using an internal hexagonal wrench, the internal hexagonal knob 1004 is turned, which drives the lead screw 1001 to rotate. 001 drives gear 1005 to rotate, and gear 1005 drives the two corresponding racks 1003 to slide away from each other, so that one end of rack 1003 is inserted into the corresponding limiting groove 102 in positioning groove 101, thereby limiting and fixing the support plate module 2. At the same time, lead screw 1001 drives slider 1002 to slide down in positioning rod 9. Since lead screw 1001 and slider 1002 have self-locking characteristics, the stability of rack 1003 can be improved. By setting limiting component 10, the support plate module 2 can be repeatedly installed and disassembled, thereby facilitating the maintenance or replacement of support plate module 2.

[0024] The thermal insulation board 3 is installed on the upper surface of the support plate module 2. The reflective film 4 is laid on the upper surface of the thermal insulation board 3. The mounting plate 5 is installed on the upper surface of the reflective film 4. The mounting plate 5 has a pipe groove 501. There are mounting holes 502 at the four corners of the mounting plate 5. Bolts 6 are inserted through the four mounting holes 502 and are inserted through the thermal insulation board 3 and the reflective film 4. Nuts matching the bolts 6 are embedded at the four corners of the upper surface of the support plate module 2. The bottom end of the bolts 6 can be threaded into the corresponding nuts. Protective pads 7 are placed in the four mounting holes 502. 6. Use nuts to install and fix the mounting plate 5, reflective film 4, and thermal insulation board 3 onto the support plate module 2. The heating pipes can be laid in the pipe groove 501 on the mounting plate 5. After installation, there is no need to backfill with concrete or cement. The floor tiles or flooring can be directly leveled on the mounting plate 5 and installed horizontally on the upper surface of the mounting plate 5. The protective pad 7 can prevent the installation materials of the floor tiles or base plate from falling into the mounting hole 502, which would affect the disassembly of the bolts 6 later, thus facilitating the disassembly and replacement of the mounting plate 5. The thermal insulation board 3 can achieve thermal insulation, and the reflective film 4 is used to reflect heat upwards and reduce downward heat loss.

[0025] Multiple support components 8 are arranged in an array on the lower surface of the support plate module 2. Each support component 8 includes a sleeve 801, which is fixedly installed on the lower surface of the support plate module 2. Threaded rods 803 are rotatably installed inside each sleeve 801. Each threaded rod 803 has an internal hexagonal groove 804 at its top. Support legs 802 are slidably inserted into each sleeve 801, with the threaded rods 803 threaded into their corresponding support legs 802. The tops of the threaded rods 803 and the internal hexagonal knobs 1004 are flush with the upper surface of the support plate module 2. Depending on the flatness of the ground, an internal hexagonal wrench can be inserted into the internal hexagonal groove 804 at the top of the threaded rod 803 to turn it. The threaded rods 803 drive the support legs 802 to slide and descend within the sleeves 801, causing the bottom of the support legs 802 to contact the ground. Thus, the support components 8, in conjunction with the support plate module 2, can achieve the purpose of load-bearing.

[0026] Working principle: When using this utility model, firstly, the keel frame 1 is installed on the wall of the room using an expansion screw and a level. Then, the support plate module 2 is installed on the keel frame 1, so that the positioning rod 9 on the support plate module 2 is inserted into the corresponding positioning groove 101 on the keel frame 1. Then, the Allen wrench is used to turn the Allen knob 1004, which drives the lead screw 1001 to rotate. The lead screw 1001 drives the gear 1005 to rotate, and the gear 1005 drives the two corresponding gears 1003 to slide away from each other, so that one end of the gear 1003 is inserted into the corresponding limiting groove 102 in the positioning groove 101 to limit and fix the support plate module 2. At the same time, the lead screw 1001 drives the slider 1002 to slide down in the positioning rod 9. Since the lead screw 1001 and the slider 1002 have a self-locking characteristic, the stability of the gear 1003 can be improved.

[0027] Next, depending on the flatness of the ground, use an Allen wrench to insert into the Allen groove 804 at the top of the threaded rod 803 and turn the threaded rod 803. The threaded rod 803 drives the support leg 802 to slide down in the sleeve 801, so that the bottom end of the support leg 802 contacts the ground. Thus, the support component 8 can be used in conjunction with the support plate module 2 to achieve the purpose of bearing the load.

[0028] Then, using bolts 6 and nuts, the mounting plate 5, reflective film 4, and thermal insulation board 3 are installed and fixed on the support plate module 2. The heating pipes can be laid in the pipe groove 501 on the mounting plate 5. The thermal insulation board 3 can achieve thermal insulation, and the reflective film 4 is used to reflect heat upwards and reduce downward heat loss.

[0029] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
