The invention discloses a preparation method for intelligent PVB laminated glass. The intelligent PVB laminated glass comprises a first PVB layer, a second sound-insulation layer and a third PVB layer which are successively connected. The preparation method comprises the following steps: (1) adding nanometer vanadium dioxide powder into alcohol for dissolving so as to obtain a VO2 solution, blending the VO2 solution with resin powder so as to obtain a master batch for the second sound-insulation layer and processing the master batch for the second sound-insulation layer so as to obtain the second sound-insulation layer containing a three-dimensional channel structure function layer; and (2) blending the second sound-insulation layer and PVB resin powder and carrying out co-extrusion or roll forming so as to obtain an intelligent heat-insulation sound-insulation PVB film. According to the invention, automatic temperature control and heat insulation are realized by using different light transmission and reflection properties of VO2 at different temperatures; sound insulation effect is realized via a three-dimensional channel structure and asymmetric damping; the sound insulation effect and the heat insulation effect are integrated on the PVB film so as to form the novel PVB sandwich film with heat insulation and sound insulation functions; so the functionality of the PVB film is improved, and security of the laminated glass is guaranteed.

The fiber cement board production device is reasonable in structure, simple in operation and low in cost, and the produced fiber cement board has the advantages of fire prevention, insulation, water prevention, damp prevention, heat and noise insulation, light weight, high strength, simple construction, economy, attractiveness and the like.

The invention discloses a manufacturing method of a heat and sound insulation particle board, aims to realize manufacturing of a high-strength sound and heat insulation particle board and solving of difficult formation of a closed vacuum environment by such wood composite materials as particle boards, aims to the problem that the particle boards cannot achieve better heat and sound insulation effect in the prior art, and proposes the manufacturing method of the heat and sound insulation particle board. The manufacturing method comprises the steps of: (S1) material preparation; (S2) raw material pretreatment; (S3) adhesive adding; and (S4) layered pavement: wood raw materials added with adhesive are divided into multiple parts; one part is taken out to uniformly pave in a mold; then, vacuum pipes prepared beforehand are paved in an oriented manner; another part of wood raw materials added with the adhesive is taken out to pave on the vacuum pipes paved in the oriented manner; and a plate blank is obtained by prepressing; (S5) hot-press forming; and (S6) later machining. The manufacturing method has the following beneficial effects: the closed vacuum environment is formed in the particle board, so that the particle board has part characteristics of a vacuum material, and the heat and sound insulating performance of the particle board is promoted.

The invention provides a cast-in-situ non-dismantling module combined wall integrated construction method. The cast-in-situ non-dismantling module combined wall integrated construction method comprises the following steps of (1) excavating a foundation according to the traditional construction method and arranging stand column steel bars; (2) manufacturing different sizes of building modules according to different building structures; (3) integrally connecting the different sizes of the building modules with the foundation and the stand column steel bars according to the storey height of a building; (4) pouring mixed concrete to cavities of the building modules and conducting vibrating compaction respectively; (5) conducting concrete seamless filling on an inner cavity of a whole wall module in an integral bundling and riveting mode that a cross-beam-free structure is mounted on planted bars and stand columns in an inner cavity of the whole wall module; and (6) repeating the steps (3)-(5) to complete pouring on all floors of the building in sequence. Through the cast-in-situ non-dismantling module combined wall integrated construction method, integral pouring forming is carried outthrough non-dismantled formwork concrete structures; the building modules and a main structure are constructed together, the construction procedures are reduced, the construction period is shortened,and the labor intensity of labor force is relieved. The cast-in-situ non-dismantling module combined wall integrated construction method is extensively suitable for compatible application of buildingconstruction.

The invention discloses a light-weight sound-insulating industrial building steel building and a roof. It consists of a main beam made of channel steel or H-shaped steel, two parallel main beams connected at intervals, and a secondary beam made of profiled steel. Acoustic insulation. The floor of the present invention has the characteristics of light weight, high strength, heat and sound insulation, non-toxic, environmental protection, fireproof, moisture-proof, and waterproof; one floor is a unit, which can be bulk-packed at the construction site or industrially produced in batches in the factory. The site installation speed is fast, the cost is low, and the housing cost is reduced; when the floor is constructed, the labor intensity of the workers is reduced, and the environmental pollution during construction and future demolition is greatly reduced. At the same time, the steel after demolition can also be recycled. The floor can be used in fields such as low-rise, multi-storey and high-rise industrial and civil buildings.
