Background

With the continuous development of the building industry, the living space of human beings is improved, and the requirements on the comfort level, the quietness and the privacy density of the space are higher and higher. In the past, the public building spaces or special spaces such as movie theaters, multi-functional halls, conference rooms and the like are often subjected to acoustic treatment, but the sound insulation or noise elimination treatment is rarely performed on common rooms, the acoustic treatment of the former is different from the acoustic treatment of the latter, the former mainly aims at meeting the reverberation time in halls to obtain excellent acoustic effects, and the latter aims at isolating the influence of external noise as much as possible and avoiding the influence of the noise generated by the former on adjacent rooms.

In order to realize the internal partition of a building, the traditional internal partition wall is constructed by using an old brick wall or a block wall, and the process comprises a plurality of procedures of slurry mixing, brick laying, plastering and the like, so that the process is labor-consuming and time-consuming, poor in flatness, high in density, heavy in weight and insufficient in construction efficiency. To the problem of traditional interior partition wall, also comparatively frivolous partition wall has now appeared. For example, CN201220370621 discloses a rock wool partition board, which adopts a structure that fire-proof plates are bonded on two sides of a rock wool plate, and has the effects of heat preservation, heat insulation, fire prevention and sound insulation, and increases the use area of a building. However, in the actual decoration and finishing construction process, because the partition wall is internally provided with electric pipelines and the like, gaps or cavities inevitably occur, and the effects of sound insulation, heat preservation and the like are influenced. In addition, the existing indoor sound insulation structure is not attractive in structure and poor in sound insulation effect because the sound insulation material is directly attached to the wall body through the fastening piece, and the existing indoor sound insulation structure can additionally occupy indoor space and is difficult to adapt to occasions with high requirements on decoration.

Meanwhile, in order to realize the heat preservation function of the wall body, at present, researches are carried out to directly add phase-change substances into concrete mortar or other wall body raw materials, but the overall performance and the service life of the building wall body are influenced. Moreover, because the phase-change materials in the raw materials are difficult to replace, the heat-insulating effect of the wall body is also reduced along with the continuous attenuation of the phase-change energy storage performance of the phase-change materials along with the time.

Although the currently adopted field monitoring technologies including GPS, video camera and other technologies alleviate the workload of manual monitoring of the field to a certain extent and improve the efficiency, the identification and judgment of the monitoring state still mainly depends on the experience of the manager, the monitoring information is manually entered, and is transmitted and communicated in a paper file and oral form, which easily causes information retention, and the real-time and informatization of construction monitoring are difficult to realize, which needs to be continuously and deeply explored and improved in technologies and methods.
