Description

Technical Field

[0001] This utility model relates to the field of prefabricated composite panel technology, and in particular to a novel prefabricated aerogel product sound insulation, sound absorption, heat insulation, and thermal insulation thin single top chord, single bottom chord, double web bar composite panel. 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 aerogel product: a thin single-upper-chord, single-lower-chord, double-web-stirred composite panel that provides sound insulation, sound absorption, heat insulation, and thermal insulation. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a novel assembled aerogel product sound insulation, sound absorption, heat insulation, thin single top chord, single bottom chord, double 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 aerogel product sound insulation, sound absorption, heat insulation, thin single-upper-chord, single-lower-chord, double-web reinforced composite slab, including a truss, fine stone concrete below the truss, composite carbon fiber mesh below the fine stone concrete, nano-aerogel bonding coating below the composite carbon fiber mesh, nanoporous aerogel composite insulation product below the nanoporous aerogel composite insulation product, nano-aerogel bonding coating two below the nano-aerogel bonding coating two, inorganic permeable molded polystyrene board below the inorganic permeable molded polystyrene board, composite carbon fiber mesh two below the inorganic permeable molded polystyrene board, connecting and fixing studs below the composite carbon fiber mesh two, and nano-aerogel modified perlite crack-resistant bonding mortar below the connecting and fixing studs;

[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 nanoporous aerogel composite insulation products are provided, and a nano-aerogel adhesive coating is applied between every two nanoporous aerogel composite insulation products.

[0008] Preferably, the flared leg is fixedly connected to the web reinforcement, and each truss has two web reinforcements inside.

[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.
