When it comes to honeycomb structural panels, designers are familiar with them. But there are always various questions when you want to use it. Today, I combed this article on super dry goods for your reference.

01.

What is honeycomb panel?

Honeycomb plate refers to the plate made of two thin panels bonded and compounded with honeycomb core materials of different heights, also known as honeycomb sandwich structure.

Why honeycomb core？

Honeycomb panel is a high-strength new environmental protection building composite developed according to the principle of honeycomb structure bionics.

The honeycomb is composed of small hexagonal prism shaped front chambers arranged neatly. The bottom of each small front room is composed of three identical diamonds.

These structures are exactly the same as the obtuse angle of 109 ° 28 'and the acute angle of 70 ° 32' of the diamond accurately calculated by modern mathematicians.

The exquisite characteristics of honeycomb structure

High material utility：

The hexagonal unit of honeycomb has proved to be the structure that saves the most raw materials and creates the maximum space utilization.

High structural strength:

Excellent compression, bending and shear properties.

The strength of 25mm honeycomb plate is 15 times that of 3mm aluminum plate, and the stiffness is 128 times.

Sandwich structure (composite structure) can give full play to the tensile and compressive properties of inner and outer metal skins.

Light weight and strong structure:

Large plate surface：

The maximum size of honeycomb plate can reach 2500mm * 12000mm, which is 5 times that of conventional 3mm aluminum plate.

Surface flatness：

Surface materials can be compounded with different materials：

Such as aluminum alloy plate, stainless steel plate, pure copper plate, titanium zinc plate, pure titanium plate, natural stone, wood veneer, glass, etc.

It is easy to install and can be processed into special-shaped plate：

Generally, large installation equipment is not required, which is suitable for the installation of unit curtain wall. The material weight is light and the installation cost is reduced.

Application scope of honeycomb panel in construction field

Honeycomb panel can be used for building curtain wall and interior wall decoration, and can also be used for ceiling. The common honeycomb structural plates on the market are mainly divided into two categories: decorative honeycomb plate and functional honeycomb plate.

Its advantages include:

1、Meet the requirements of thermal expansion and cold contraction of metal curtain wall;

2、The plate surface does not need riveting, and there is no mechanical damage;

3、3mm flat joint, can be divided by large plate surface, and the building facade is more concise and beautiful;

4、EPDM dry sealing strip is used for sealing and waterproof design to ensure air tightness and water tightness and meet the four property requirements of curtain wall;

5、The installation is not affected by the season, so as to solve the problem that glue cannot be applied on the construction site in winter in the north.

It has been tested and certified by the national authority: the air tightness and water tightness have reached the highest level 4 and 5 respectively, the wind pressure resistance is level 8, and the in-plane deformation is level 3, which fully meets the requirements of the national standard of metal curtain wall.

「Application case」

Tianjin Binhai airport terminal

The curtain wall system installed on the back can complete the installation of honeycomb panels at the cornice without scaffold. It not only does not affect the construction progress of the working surface under the cornice, but also saves the cost of the scaffold.

Qingdao CTV animation City

The plug-in installation method is adopted, and the maximum specification of the honeycomb plate is nearly 10m long, and excellent flatness is maintained. At the corner of the exterior wall, an integrated seamless corner board is used to outline the three-dimensional and smooth outline of the building. It took only two months from the project order receiving to the completion of wall slab construction.

「Application as sunshade and line decoration」

Here we want to talk about the SC honeycomb structure sunshade, which is no longer used as plane decoration, but vertical and facade, opening a new trend of building sunshade and line decoration.

2、Built in aluminum alloy profile to ensure the wind load resistance and installation strength of the plate;

3、Compared with the fluorocarbon coating on the pre roll, it has excellent weather resistance and durability;

4、Compared with traditional extruded profiles and aluminum veneer components, it has more weight advantages and effectively reduces the building load;

5、The super large size brings more plasticity to the architectural decoration style.

「Application case」

China rice paper Museum

The honeycomb panels used in the project are not used for the facade decoration of the wall, but are hung outside the glass curtain wall and stacked horizontally to create an open rice paper shape. In order to avoid downward bending of large-size plates, profiles with a certain thickness are placed inside each plate to ensure that the plate can maintain excellent flatness and installation strength for a long time.

Woolworths global supermarket chain

In this project, sc50 honeycomb sunshade shutters of 31 different colors are used as sunshade and decoration materials to be installed on the facade of the supermarket, and the wind load resistance and installation strength of the board are increased by built-in aluminum alloy profiles. It also has excellent strength when used as shading and line decoration of high-rise buildings.

The surface coating adopts pre roll fluorocarbon baking paint process, which has excellent weather resistance and corrosion resistance, so that the plate has uniform and long-lasting color.
