Description
Technical Field
The utility model belongs to the technical field of novel building wall materials, and particularly relates to a plug-and-play phase change building block.
Background
Proper heat preservation and insulation materials are selected to be embedded into the building wall, so that the heat preservation and insulation capacity of the wall is improved, the heat stability of a building is improved, the energy consumption of a building heating air conditioner is reduced, and the aim of building energy conservation is achieved. The building block is a main material of masonry structure with wider application in industrial development of buildings in China, has the advantages of simple manufacturing equipment, high masonry speed, strong applicability and the like, and can be used as a main material of a bearing wall and a main material of a non-bearing wall. Compared with a reinforced concrete structure, the masonry structure can save cement and steel, and the masonry structure does not need templates and special technical equipment, is convenient to construct and is suitable for various building types. Integrating phase change material (PHASE CHANGE MATERIAL, PCM) into the block can increase the heat storage of the wall without requiring large amounts of material, as smaller amounts of PCM can absorb large amounts of heat during the phase change process. Therefore, for the building outer protective structure using the phase change block as a main material, it is possible to absorb and store most of heat transferred from a hot outdoor through a wall during the daytime and release the stored heat when the ambient temperature is lower than the melting temperature of the PCM. Based on the heat accumulating and releasing process of the PCM, the PCM wall body can reduce the indoor air temperature, transfer peak load and reduce indoor temperature fluctuation.
Along with the continuous promotion of the energy-saving aim of the construction in China, higher requirements are also provided for the thermal performance of the composite self-heat-insulation building block, and how to develop the concrete composite self-heat-insulation building block to meet the energy-saving design standard and market demands becomes a further challenge in the industry. Therefore, a phase change building block which is easy to manufacture and use is needed to meet the requirements of heat preservation and energy saving of the outer wall of a building.
Currently, there are several existing structures for integrating PCM into blocks:
(1) The PCM is directly immersed into the base material of the building block, but the leakage problem of the structure is serious, and chemical action can be generated between the PCM and the building block, so that the mechanical property of the base material of the building block is affected;
(2) CN201120340079.4 discloses a light heat-insulating building block containing microcapsule phase-change material, the PCM microcapsule is directly added into the base material of the building block, the PCM microcapsule can effectively prevent the leakage problem of PCM, but the PCM microcapsule is directly added into the base material of the building block, the following technical defects also exist: PCM leakage and a decrease in the compressive strength of the construction material due to the damage of the microcapsules during the construction mixing/processing; the design difficulty of the mixing proportion of the base material added with the PCM microcapsule is high, the building block is not easy to form, the hardening time is long, and the construction period can be prolonged in the actual construction process;
(3) CN201410660954.5 patent discloses a composite block filled with gypsum-based phase change material, which is prepared by mixing PCM, gypsum and other materials, and water, and is filled into rectangular blind holes of the block. Although the method can slow down the leakage problem of the direct impregnation method, the construction period of the blind holes is long. In addition, the problem of leakage of PCM due to permeation still cannot be avoided after long-term use.
To sum up, when the PCM is combined with the building block, the structure is simple, the applicability is high, the tolerance is strong, the phase change material is not easy to leak, the production is easy, the strength is high, and the use is convenient.
