Description

Technical Field

[0001] This utility model relates to the field of modular floor system technology, specifically to a prefabricated floor system including a heating system. Background Technology

[0002] Traditional underfloor heating systems typically employ a wet construction process, which involves laying an insulation layer and underfloor heating pipes on the structural floor slab, followed by pouring a concrete leveling layer, and finally laying a decorative surface layer. This construction method suffers from complex procedures, a long construction period, and the potential for pollution from wet materials. Furthermore, because the pipelines are embedded within the concrete layer, future maintenance is difficult, and the overall weight of the underfloor system places high demands on the building's structural load-bearing capacity.

[0003] In recent years, prefabricated raised floor systems have been increasingly adopted. These systems separate the decorative floor layer from the structural layer using supporting components, creating a cavity for pipework installation. However, existing raised floor systems still suffer from problems such as insufficient stability of the supporting structure, inconvenient leveling operations, and potential pipework conflicts. Some systems use a keel support method, which occupies a large space, affects floor height utilization, and makes precise leveling difficult. Furthermore, when traditional raised floors are combined with heating systems, they often suffer from low heat transfer efficiency and difficulty in ensuring floor flatness, affecting user comfort and durability. Therefore, there is an urgent need for a prefabricated floor solution that combines rapid installation, high stability, and efficient heating. Utility Model Content

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0035] In practical use, the prefabricated ground system with heating system described in this utility model includes a pipeline separation cavity layer 2, a through-hole foot assembly 3, a base layer suspended board 4, a thermal insulation structure layer 5, a floor heating pipe groove 6, a buffer balance plate 7, and a decorative panel 8.

[0036] A base layer slab 4 is leveled and connected above the structural floor deck 1 via a through-hole anchor assembly 3. A pipeline separation cavity layer 2 for laying pipelines is formed between the base layer slab 4 and the structural floor deck 1. An insulation structural layer 5 is installed above the base layer slab 4 using modified silicone sealant. Underfloor heating pipe grooves 6 for laying underfloor heating pipes are opened on the insulation structural layer 5.

[0037] In one embodiment, the decorative panel 8 is a ceramic tile, and the ceramic tile is connected to the buffer balance board 7 by ceramic tile adhesive; in another embodiment, the decorative panel 8 is a wooden floor, and a floor moisture-proof pad is provided between the wooden floor and the buffer balance board 7.

[0038] The through-hole anchor assembly 3 includes a bolt support rod and a rubber anchor. The rubber anchor is provided with a side insertion port 15.

A skirting board 11 is provided between the decorative panel 8 at the edge of the prefabricated floor system with heating system and the composite wall 10.

[0040] This is a prefabricated floor system with a heating system. Related specifications:

[0041] I. Includes through-hole foundation assembly 3, base raised board 4, thermal insulation structure layer 5, buffer balance board 7, and decorative panel 8;

[0042] 2. Several prefabricated holes 14 are pre-arranged on the base suspended slab 4. Each prefabricated hole 14 is provided with a through hole anchor component 3. The bottom surface of the through hole anchor component 3 is connected to the structural floor deck 1. The base suspended slab 4 is then suspended above the structural floor deck 1 through several through hole anchor components 3. The base suspended slab 4 is a high-load suspended ground fiber cement board.

[0043] 3. By increasing high-strength fibers and optimizing material ratios, the goal of achieving high strength, environmental protection, and convenient processing is achieved, thereby increasing the load-bearing capacity of the base layer suspended board 4 under concentrated loads without increasing the density of the board.

[0044] IV. Point support: The system is supported by the through-hole anchor bolts of the through-hole anchor component 3 of the ground system. The through-hole anchor bolts have no keel support and are small in size, ensuring that the support space is less than the number of the elevated floor / 1000. While ensuring the stress on the elevated ground, the anchor bolts are prevented from colliding with the pipelines set in the pipeline separation cavity layer 2, so as to achieve the purpose of pipeline separation in a simpler and more reasonable way.

[0045] V. Top Leveling: The front leveling method allows workers to stand on top of the base raised slab 4 to perform leveling, improving ground flatness and solving the space problem when adjusting the raised ground;

[0046] VI. Foaming and Rooting: The through-hole anchor component 3 and the structural floor deck 1 are bonded together using polyurethane adhesive through microcrystalline penetration. Because the groups in the polyurethane adhesive molecular chain can react with various functional groups containing active hydrogen to form interfacial chemical bonds, it has strong adhesion to various materials. After curing, it has high strength and a certain degree of elasticity, which can play a role in fixing and buffering. It also roots the base raised floor 4, the through-hole anchor component 3, and the structural floor deck 1 into one unit, and fixes the internal structure of the through-hole anchor bolts of the through-hole anchor component 3 to prevent the bolts of the through-hole anchor component 3 from recuring, ensuring that the raised floor system is free of abnormal noise during long-term use.

[0047] The relevant parameter requirements for this type of prefabricated floor system with heating system are as follows:

[0048] 1. The base slab 4 has pre-drilled holes 14 in the factory. The pre-drilled holes 14 are the bolt support points of the anchor components 3: 100mm≤ center distance of the pre-drilled holes 14≤400mm; 20mm≤ distance of the pre-drilled holes 14 from the edge of the base slab 4≤50mm.

[0049] 2. When laying the base slab, expansion joints must be reserved, with an expansion joint size of 5mm ≤ 20mm;

[0050] III. Fixing method: The base suspended slab 4 is distributed in units according to the slabs. Each unit is equipped with a through-hole anchor component 3 and fixed to the structural floor deck 1 by foaming and rooting process. Adjacent base suspended slabs 4 are not fixed to each other.

[0051] IV. Load requirements: The load on the three points of the through-hole anchor assembly on the base slab 4 is greater than 4000N (tested by a 20mm*20mm pressure head).

[0052] The following is an introduction to the installation of the ground-based overhead system:

[0053] Step 1: Clean the ground, removing any obstacles or dust that may affect the installation of the raised floor;

[0054] Step 2: Horizontal measurement. Use an infrared laser to find the high and low points of the room, calculate the average height, and make horizontal marks on the four walls to determine the correct height of the stilt.

[0055] Step 3: Assembly of the elevated modules. Leveling feet components will be installed on the prefabricated base slabs with holes processed in the factory to form the elevated modules.

[0056] Step 4: Install the overhead modules. Lay the overhead modules according to the layout diagram. Adjust the flatness by adjusting the top of the anchor components. At the same time, use an infrared laser to level the surface. After the flatness adjustment is completed, drip polyurethane foam from the top of the anchor components to ensure that the bottom of the anchor components is bonded to the structure and increase its stability.

[0057] Step 5: Install underfloor heating modules. Select XPS insulation modules with underfloor heating pipe grooves according to the design. Lay the underfloor heating pipes inside the grooves. If you choose not to install underfloor heating, this step is not required.

[0058] Step 6: Laying the balancing layer. Use 8mm OFC boards and lay them on the surface of the underfloor heating module. The boards need to be laid with staggered joints from the underfloor heating module or the overhead module. If there is no underfloor heating system, the boards can be laid directly on the overhead module.

[0059] Step 7: Finishing installation. In addition to wood flooring, you can also choose finishing materials such as ceramic tiles and SPC flooring.

[0060] The above is an introduction to the installation of prefabricated floor systems including heating systems.

[0061] In summary, by utilizing the above-mentioned technical solution of this utility model, through the optimized and improved design of the prefabricated ground system with heating system, point support and leveling on the board are achieved by using through-hole anchor components, combined with polyurethane adhesive foaming and rooting process, the support stability and construction convenience are improved; flexible pipeline layout is achieved through pipeline separation cavity layer; thus, the ground system has advantages such as reverse disassembly, green environmental protection, constant temperature and noise reduction, and achieves a comprehensive effect of high construction efficiency, convenient maintenance, energy saving and comfort.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
