Description

Combined dry floor heating module

technical field

The utility model relates to a ground radiation heating floor heating, in particular to a combined dry floor heating module which uses low-temperature hot water as a heat medium and quickly transfers heat to an integrated module through a heating pipe embedded in a combined floor heating module. .

Background technique

At present, the known ground radiation construction method is above the floor layer, firstly: laying a thermal insulation layer (EPS foam board-thickness 20mm, density 20, non-flame retardant or foam cement 30-40mm), secondly: laying and fixing heating Pipes (PEX with a diameter of 20mm, PE-RT PB and other pipes), again: filling layer (bean stone concrete with a thickness of 40mm-site mixing construction), and finally: leveling layer (cement mortar grinding surface with a thickness of 10-20mm-site Mixing construction) and other structural processes.

This wet ground radiant heating construction method has the following defects:

1. Cross-construction, Chengbao failed.

The best time to start the floor heating project is when the main body of the building is capped, and the sub-projects such as interior wall painting, integrated wiring, plumbing pipes, and toilet waterproofing are completed. However, the reality is that cross-construction has to be done. In order to deliver the houses on time, some developers will inevitably rush the progress. In this way, the result is: on the one hand, floor heating construction companies that enter the site ahead of time often delay work because the civil engineering party cannot provide work on schedule, which increases management costs; on the other hand, It also increases the coordination difficulty and management cost of the civil engineering party; thirdly, the floor heating company hastily constructs, and before the initial setting period of the concrete passes, it carries out the construction of other processes, causing the base layer before laying the insulation board to be uneven, resulting in hollowing and empty paving. ; Some pipes are exposed, workers step on them, the wall thickness of the pipes is thinned, and even cracks and leaks; the water in the cushion has not evaporated, so ceramic tiles, marble and wooden floors are started. Once the heat is supplied, the hot air will go up. If the ground cracks and bulges, its heating effect and service life will be greatly reduced.

2. It does not occupy an area, but grabs space.

According to the requirements of the "Regulations", the thickness of the bean stone concrete backfill is at least 30mm on the heating pipe, that is, the cushion layer is not less than 50mm thick, and the insulation layer is at least 20mm thick, then only the total thickness of the structural layer of the floor heating project Has reached 70mm ~ 90mm. This thickness is undoubtedly a large number compared to residential buildings. If the median value of 80mm or 0.08m is taken as the calculation basis, a high-rise building with about 30 floors can almost have an extra floor area.

3. Increase the load and double the investment.

The density of pea stone concrete is 2500/m ³ , and the thickness of the floor heating backfill layer is calculated according to the most conservative 50mm-60mm, so the weight is 120-150kg/m ² . For a residential area of 100,000 m ² , the weight of the ground heating backfill layer alone is 12,000 tons, and the direct cost increase is not less than 3 million yuan. If the direct costs of earthwork, cement, steel bars, etc. and matching costs increased are included, the total cost of a floor heating project is actually equivalent to twice the direct cost of the floor heating project, which is an astonishing figure for an investor in a real estate project. .

4. Large heat loss and large water consumption.

Check the JGJ142-2004 "Technical Regulations for Ground Radiant Heating" appendix "A.1 Heat dissipation and downward heat transfer loss per unit floor area", it can be seen that the heat loss of floor heating accounts for about 28% of the heat dissipation, which means that nearly 30% of the heat is doing useless work. Usually, the flow rate of water in a De20*1.9mm heating tube is about 300kh/h, and the water consumption is relatively large.

5. On-site assembly, high randomness.

Floor heating is an on-site assembly project. Manufacturers need to transport large and small materials such as heating pipes, water separators, insulation boards, aluminum foil, staples, and steel wire mesh to the construction site for assembly. Due to the differences in on-site supervision and workers' quality, the spacing between pipes and the thickness of insulation boards are different. The increase of many uncertain factors such as the height of concrete, that is, the increase of uncertain factors of project quality. At the same time, it will inevitably cause the mixing, vibration, dust, noise and pollution of a large amount of construction waste on the construction site.

6. The solid period of concrete is long, and decoration is troublesome.

The final setting period of pea stone concrete is 28 days. In the case of poor ventilation and drying, the drying and curing time will be longer. The laying of decorative surface materials (wooden floors, ceramic tiles, marble, etc.) must be carried out after the concrete is completely dry, otherwise it will cause cracking, swelling or water stains on the surface materials, which will seriously affect the appearance and use effect. Many construction sites rush to lay surface materials before the concrete is completely dry in order to meet the construction deadline. Objectively speaking, it is unrealistic to wait until the concrete is completely dry before proceeding with the construction of other processes. In the same way, during the renovation period, damage to the heating pipe due to nailing, cutting materials, etc. is almost inevitable.

7. Uneven expansion and cracks on the ground.

One side of the floor heating pipe is in soft contact with the insulation board, and the other three sides are hard-wrapped by concrete. When the heating pipe is heated or expands under pressure, the space for expansion and contraction of its linear displacement must be very limited. Because the stress produced by the heating pipe after heating with hot water is greater than the tensile strength of the concrete, the surface of the concrete cushion is prone to cracks, and in severe cases, the decorative surface material can be cracked. In addition, the heating pipe is directly in contact with the pea-stone concrete. During the backfilling process, scratches are easily generated, causing leakage, and burying hidden dangers for future use.

8. Once formed, maintenance is difficult.

Floor heating is a kind of on-site assembly, one-time molding, and a concealed system engineering that is almost impossible to repair. Once the heating pipe leaks, it will cause trouble during the maintenance period. No matter what method is used to find the leak, the decorative surface must be damaged. It is very difficult to find a material with the same design, color and pattern as the original surface layer material after the leak point is connected, and customer complaints are inevitable. In addition, no matter what connection method is used (usually there are direct mechanical connections such as copper and electric fusion connections), there is a hidden danger of secondary leakage.
