[0001] This utility model relates to the field of prefabricated composite slab technology, and in particular to a novel prefabricated thin single-upper-chord single-lower-chord single-web-stirrer composite slab with damping felt for sound insulation, sound absorption, heat insulation and thermal insulation. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slab are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] However, existing prefabricated composite panels do not have sound insulation properties and are even quite heavy, affecting their handling and processing. To address this, we propose a new type of prefabricated damping felt sound insulation, sound absorption, heat insulation, thin single-upper-chord, single-lower-chord, single-web-stirred composite panel.

Both sides of the web member are provided with flared ends, and a reinforcing rib is provided above the flared ends.

[0007] Preferably, multiple damping sound insulation felts are provided, and a nano-aerogel bonding coating is attached between every two damping sound insulation felts.

[0008] Preferably, the reinforcing rib is fixedly connected to the flared foot, and the flared foot is fixedly connected to the web rib.

[0009] Preferably, the thickness of the fine aggregate concrete is 15-60mm, and the nano-aerogel modified perlite crack-resistant bonding mortar includes, but is not limited to, high-performance concrete, self-compacting concrete, high-strength concrete, ultra-high performance concrete (UHPC), and high-ductility concrete.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0011] This utility model is lighter and easier to transport and construct, reducing installation and usage costs.
