Description

Technical Field

[0001] The invention belongs to the technical field of honeycomb aluminum panels, and in particular relates to a hyperbolic ultra-microporous honeycomb aluminum panel and a unitized ceiling installation process. Background Art

[0002] Hyperbolic ultra-microporous sound-absorbing honeycomb aluminum panel is a high-performance metal composite panel that combines the advantages of hyperbolic shape and ultra-microporous sound absorption technology. The panel uses an aluminum honeycomb core as the core layer, and is covered on both sides with specially punched aluminum panels and bottom plates. These micropores are usually less than 0.25mm and are arranged in regular dot patterns, which can effectively absorb and dissipate sound waves and achieve excellent sound absorption and noise reduction effects. At the same time, its hyperbolic design is not only beautiful and unique, but also provides better acoustic performance and spatial decoration effects. It is suitable for various places that require sound absorption and decorative functions, such as theaters, concert halls, conference rooms, etc.

[0003] In traditional large-area ceiling construction, due to the lack of accurate hyperbolic modeling technology, complex shapes often rely on manual experience for lofting, which is prone to dimensional deviation, seam misalignment and other problems, resulting in low installation efficiency and high material loss rate. On-site manual processing of hyperbolic aluminum plates not only takes a long time, but also makes it difficult to ensure the surface accuracy and acoustic performance, which can easily lead to defects such as insufficient sound absorption coefficient and substandard opening rate, and cannot meet the stringent requirements of the multi-functional hall for the acoustic environment. Existing processes mostly use heavy steel keels for on-site welding, which are bulky and have high risks for high-altitude operations. Hoisting relies on a single device, with poor synchronization, which can easily cause deformation of unit plates or uneven installation, affecting the overall aesthetics and durability. In addition, traditional ceiling construction lacks unit prefabrication and systematic hanger design, the on-site adjustment process is cumbersome, and the keel connection spot welding is not strong, which can easily cause safety hazards. Decentralized construction management is also difficult to ensure the overall coordination of large-span column-free space ceilings, which ultimately leads to unstable project quality, difficulty in balancing function and aesthetics, and restricts the efficient construction and use experience of complex spaces. . Summary of the invention

[0004] The purpose of the present invention is to provide a hyperbolic ultra-microporous honeycomb aluminum panel and a unitized ceiling installation process to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hyperbolic ultra-microporous honeycomb aluminum plate, comprising an aluminum plate main body, the middle part of which is bent upward to form a unidirectional arc surface, and the four corners of the aluminum plate main body protrude outward, and the four sides of the aluminum plate main body are symmetrically bent. Since this structure is a prior art product, it is not further described here; the aluminum plate main body comprises a micro-perforated aluminum plate and a main perforated aluminum plate placed outside, and an aluminum honeycomb core material is also arranged between the micro-perforated aluminum plate and the main perforated aluminum plate, a non-woven fabric 1 is arranged between the aluminum honeycomb core material and the micro-perforated aluminum plate, and a non-woven fabric 2 is arranged between the aluminum honeycomb core material and the main perforated aluminum plate; the acoustic performance is excellent, the measured sound absorption coefficient NRC reaches 0.84, and the opening rate exceeds the design requirement by ≥20%, providing a high-quality acoustic environment for the multi-function hall to meet the needs of multiple scenes such as conferences and exhibitions.

[0009] Step 1: Measure and lay out;

[0010] Step 2: Digital modeling and ordering: Use a total station to collect data on the hyperbolic sound-absorbing honeycomb aluminum ceiling, enter the data into the BIM 3D modeling software for reverse modeling, generate an accurate 3D digital model, and model each hyperbolic sound-absorbing honeycomb aluminum ceiling individually;

[0011] Step 3: Installation of the transfer layer. Construction is carried out according to the steel frame drawings. The dividing lines are laid out on the ground on site. The components of the transfer layer are processed in the factory and assembled on the ground on site. The overall lifting method is adopted to lift, install and fix them at one time.

[0012] Step 4: Install the keel and special hanging parts. Install the card-type main keel on the transfer layer. Insert the hanging parts into the corresponding hanging bolts according to the position of the dividing line and tighten the nuts. Install the connectors at the joints of the main keels. Adjust the elevation, arch and straightness with the wire. Install the special hanging parts of the honeycomb panel on the main keel, adjust the spacing, and insert the Z-shaped keel.

[0013] Step 5: The hyperbolic ultra-microporous sound-absorbing honeycomb aluminum panels are installed in units. The main body of the aluminum panels that make up a unit panel is pre-assembled according to the number, the large keel at the joint is cut, and a fixed-length curved 40*20*2 hot-dip galvanized square tube is added as the unit panel assembly fixed keel, and then a 40*20*2 hot-dip galvanized square tube is welded on the upper part as the hoisting keel. The hyperbolic ultra-microporous honeycomb aluminum panels, back-attached secondary keels, adjustable connectors, etc. are factory-formed in one piece, and the on-site lofting and positioning are carried out, and the unitized efficient installation requirements are achieved by using dual-machine synchronous jacking;

The factory prefabrication and unitized assembly mode effectively reduce the amount of on-site work and shorten the construction period. At the same time, through the lightweight and high-strength keel and special hanger system, the structural stability and the lightweight requirements of the ceiling are taken into account. During the construction process, double scissor trucks are used for synchronous lifting and straight arms The vehicle lifting technology not only ensures the safety of high-altitude operations, but also improves the installation efficiency of unit panels and adapts to the construction needs of large-span spaces. In addition, the hyperbolic ultra-microporous sound-absorbing honeycomb aluminum panels have excellent acoustic performance, with the measured sound absorption coefficient NRC reaching 0.84 and the opening rate exceeding the design requirements (≥20%), providing a high-quality acoustic environment for the multi-function hall and meeting the needs of multiple scenarios such as conferences and exhibitions.
