Sound-absorbing porous foam concrete composite board and preparation method thereof

PendingCN122358789AFoam concreteInsulation layer
This invention belongs to the field of building materials technology, specifically disclosing a sound-absorbing porous foamed concrete composite board and its preparation method. Using foamed concrete as the substrate of the composite board effectively solves the problem of poor environmental performance of traditional sound insulation materials. Compared with materials such as polystyrene and sound-absorbing rock wool, it does not require a large amount of energy for preparation and can utilize recycled raw materials. It does not produce toxic powder after aging, reducing harm to the air environment and human health, while also avoiding the flammability hazards of traditional materials. The closed-cell sound insulation layer's sealed pores can block direct sound wave penetration, achieving basic sound insulation. The sound-absorbing pores of the porous sound-absorbing layer, combined with the interconnected channels, introduce incident sound waves into the interior. Energy is dissipated through reflection and friction within the channels, forming a dual protection of "sound absorption and sound insulation." This solves the core problem of poor sound insulation performance of traditional concrete and compensates for the short lifespan of traditional sound insulation materials, extending the overall service life of the board.

A template-free ultra-thin high-performance laminated slab and a production process thereof

PendingCN122358810AComposite slabSupport plane
This invention relates to the field of composite slab technology, specifically to a formwork-free ultra-thin high-performance composite slab and its manufacturing process. The composite slab includes a cement base and a metal support frame installed on top of the cement base. The two sides of the cement base in the width direction are inclined structures, and the two inclined sides are parallel to each other. Each inclined side has a groove parallel to the length of the cement base. This formwork-free ultra-thin high-performance composite slab and its manufacturing process can form a seal when the two cement bases are joined by the inclined sides on the cement base. Even if there are gaps, there is no need to worry because most of the force of pouring cement is vertically downward, and the inclined structure can prevent cement penetration. Even when the gap is large, cement will not penetrate. Through the groove, a sealing strip can be inserted between the two cement bases to fill the gap between them and prevent cement from flowing downward.
