Description

Technical Field

[0001] This utility model relates to the field of prefabricated composite slab technology, and in particular to a novel prefabricated thin single-upper-chord double-lower-chord single-web-stirred 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, double-lower-chord, single-web-stirred composite panel. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of assembled damping felt sound insulation, sound absorption, heat insulation and heat insulation thin single upper chord double lower chord single web bar composite plate, which can solve the technical problems mentioned in the background.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel prefabricated sound-absorbing, heat-insulating, and sound-damping felt thin single-upper-chord, double-lower-chord, single-web-stirred composite slab, including a truss, with fine stone concrete below the truss, a composite carbon fiber mesh below the fine stone concrete, a nano-aerogel bonding coating below the composite carbon fiber mesh, a damping sound insulation felt below the nano-aerogel bonding coating, a second nano-aerogel bonding coating below the damping sound insulation felt, an inorganic infiltrated molded polystyrene board below the second nano-aerogel bonding coating, a second composite carbon fiber mesh below the inorganic infiltrated molded polystyrene board, a connecting and fixing stud below the second composite carbon fiber mesh, and a nano-aerogel-modified perlite crack-resistant bonding mortar below the connecting and fixing stud.

[0006] The truss includes an upper chord, a lower chord is provided below the upper chord, a web member is provided on one side of the lower chord, and the upper chord and the lower chord are fixedly connected by the web member. Both sides of the web member are provided with 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 flared foot is fixedly connected to the web reinforcement, and each truss has two web reinforcements and two lower chords inside, with the flared foot tilted downward at 15 degrees.

[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. It also has sound insulation, sound absorption and heat preservation functions, with excellent sound insulation effect, effectively ensuring its sound insulation effect during use. Through the development of new prefabricated floor slabs with tight splicing and four-sided reinforcement, new structural components such as high-efficiency combination columns, beams and shear walls of steel and reinforced concrete, new integrated external wall system, and digital production, installation and testing technologies of prefabricated components, a new prefabricated composite structure and supporting technology system has been formed.
