Energy-saving wall with functions of heat preservation and heating

Abstract

The invention relates to an energy-saving wall with the functions of heat preservation and heating. The energy-saving wall comprises a composite sandwich steel wire net frame heat-insulation plate, amain body layer formed by a cast-in-place reinforced concrete layer, and an outer protective layer formed by a concrete layer. An inner steel wire net piece and an outer steel wire net piece of the composite sandwich steel wire net frame heat-insulation plate are fixedly bonded in the main body layer and the outer protective layer. An inner heat-insulation layer, a heating bracket, an inner protective plate, a net cloth and a surface coating are arranged on the inner side of the main body layer in sequence. A heating pipeline is mounted in the heating bracket. A heat-insulating pad or a heat-insulating sleeve is arranged between a bracket connecting piece and the heating bracket. The inner protective plate is provided with a plurality of longitudinal through holes. At least part of longitudinal through holes is not shielded by the net cloth. According to the energy-saving wall, the heat-insulation effect of the wall is improved obviously, the heat bridge effect is reduced obviously, the proportion of heat dissipating of heating heat energy to a wall structure and an outdoor space is decreased obviously, the utilization ratio of the heating heat energy is increased obviously, and the good building energy-saving effect is obtained accordingly.

Problems solved by technology

Existing external wall insulation mainly adopts external thermal insulation system. An external thermal insulation layer is set on the outside of the concrete main wall and an external protective layer (protective layer) is set on the external side of the external thermal insulation layer. The external thermal insulation layer reduces internal and external heat exchange and minimizes summer The outdoor high temperature is transmitted to the room and the indoor heat is dissipated to the outside in winter. The setting of the external insulation layer is mainly to bond the external insulation board to the main wall after the main wall is completed, and to strengthen the insulation by setting the steel wire mesh connected with the main wall. The connection strength of the outer protective layer avoids and slows down the peeling and falling off of the outer protective layer. In order to improve the connection strength of the outer insulating layer and its outer protective layer and the main wall, people have also improved the setting mode of the outer insulating layer, for example, CN201443146U A composite sandwich steel wire grid insulation board wall structure is disclosed. The composite sandwich steel wire grid insulation board composed of insulation boards and outer protective layers is prefabricated. Steel wire mesh sheets are respectively arranged on the inner and outer sides of the insulation board and passed A number of abdominal wires passing through the insulation board connect the inner and outer steel wire mesh sheets to form a steel wire grid structure, and a prefabricated concrete layer is prefabricated on the outside of the insulation board as the outer protective layer, and the composite sandwich wire grid sandwich insulation board Concrete pouring of the main wall is performed as an external formwork, and the main wall and the insulation board are consolidated together, especially in the main wall where the inner steel wire mesh is consolidated, thereby significantly improving the firmness of the outer insulation layer and the outer protective layer However, because the insulation board is set outside the main wall, the relative temperature of the main wall is relatively high, and the abdominal wires as a guarantee of strength usually need to be densely distributed, forming a more obvious thermal bridge effect.

Existing indoor heating mainly has two heating methods: heating and floor heating. The heating area of ​​heating is small, which requires a higher heat medium temperature, and the overall heat energy utilization rate is low. Floor heating not only feels comfortable, but also requires a lower heat medium temperature , the overall heat energy utilization rate is higher than that of heating, which is a relatively energy-saving heating method. For example, CN204326454U discloses a kind of floor heating, which lays geothermal pipelines, mainly hot water pipelines, on the concrete ground substrate, fills and wipes them with concrete Flat, so that the geothermal pipelines are firmly buried in the surface concrete, and then the floor is laid on it. In order to reduce the heat dissipation from the geothermal pipelines to the concrete ground substrate, heat insulation boards and / or reflective films can be laid on the ground substrate first, and then the geothermal pipelines, but this geothermal structure still restricts the improvement of heat energy utilization rate, resulting in a certain waste of heat energy. The thermal conductivity of solid materials such as concrete is lower than that of solid materials such as concrete, and wood or similar floors also have relatively high thermal insulation capacity, so the heat energy lost through the ground matrix and wall structure is still relatively large, resulting in a certain amount of waste
