Description

Thermal insulation floor

(1) Technical field

The invention relates to a floor building component, in particular to a heat-insulating floor.

(two), background technology

Existing floors are usually not insulated, or simply covered with insulation boards. The floor itself has no heat supply and heat storage capacity, so the thermal insulation performance of the floor is relatively poor, and the effect of temperature regulation and energy saving is not obvious. With the continuous improvement of my country's building energy-saving standards and the gradual implementation of household heating metering, people have higher and higher requirements for thermal insulation on the floor of the building. in a stable temperature environment.

(3) Contents of the invention

The invention provides a thermal insulation building floor, which solves the problems of poor thermal insulation performance, poor heat supply and heat storage capacity, and weak temperature adjustment performance of the existing building floor.

The technical scheme of the heat-insulating floor of the present invention: this heat-insulating floor, the floor from bottom to top is the floor, the insulation layer, the leveling layer, and the finishing layer. The heating pipe and the phase change pipe, the heating pipe is a connecting pipe, the heating hot water circulates in the pipe, the two ends of the phase change pipe are closed, and the phase change material is filled in the pipe.

The above-mentioned heating pipes and phase change pipes are laid parallel to each other at intervals.

The above-mentioned heating pipes and phase change pipes are laid together in parallel.

The upper tube wall of the above-mentioned phase change tube has a longitudinal groove, and the heating tube is arranged in the groove of the phase change tube.

The above-mentioned insulation layer is a molded polystyrene board, an extruded polystyrene board, a polyurethane board, a foam concrete board or a rubber powder polystyrene particle insulation slurry board.

The above-mentioned leveling layer is a common mortar layer or a lightweight mortar layer with a thickness of 10-20 mm, and a metal mesh is laid in the leveling layer close to the upper surface.

The above-mentioned finishing layer is floor tile, wooden floor or stone.

There is a waterproof layer below the above-mentioned finishing layer.

The phase change material in the phase change tube is one of sulfate, phosphate, nitrate, acetate, carbonate hydrate or paraffin, acetic acid, stearic acid or a combination of at least two of the above materials.

The phase change material in the above phase change tube is the hydrate of halide salt and sulfate, phosphate, nitrate, acetate, carbonate hydrate, or at least two materials with one of paraffin, acetic acid and stearic acid Compositions.

Beneficial effects: the invention improves the structure of the floor and provides a new heat-insulating floor, through which the floor

Heating pipes are laid inside, which can circulate water heated from boilers, water heaters, solar energy, and geothermal collection devices, give full play to the utilization rate of 9 heat energy, and increase the radiation in the entire room, which is more conducive to improving the heating effect of the entire room. In the heating process, clean energy such as solar energy and geothermal energy can be fully utilized to effectively reduce environmental pollution and save fuel consumption such as coal, electricity, and gas. Phase change material is a temperature-adjustable material that absorbs heat at high temperature and releases heat at low temperature. For example, the solid-liquid conversion of paraffin wax at 20-50 °C has a phase change endothermic and exothermic process. When the ambient temperature rises , Paraffin liquefaction absorbs heat, so that the temperature of the protected object will not increase significantly due to the increase of the ambient temperature. Reduced and significantly reduced, that is to say, through the phase change heat storage of paraffin, the floor has good thermal insulation performance, making it more suitable for building insulation in hot summer and cold winter regions. Laying phase-change tubes in the floor can store excess heat and release it when the temperature drops, which not only saves energy, but also reduces energy waste, and is also conducive to controlling the indoor temperature. The role of self-regulation. The metal mesh sheet is pressed into the light mortar leveling layer, which not only has a certain strength and plays the role of crack prevention, but also has a certain heat storage function, which can play an auxiliary role in controlling the temperature in the room. Can be used on floors or floors.
