Product Description

aluminum geodesic dome roof design

 

The design of the aluminum geodesic dome roof has several geometric limitations. The first constraint is physical geometry. All beams of the dome roof are ideally the same length and all panels have the same size. This will make design, manufacture and construction simple. However, by making all beams the same length, the dome will not have any curvature. It will be a flat surface without too much (if any) structural strength. The best dome geometry is to maximize structural strength and minimize the number of different beam lengths and panel sizes.

 

However, this design has an obvious problem. The base ring is not concentric unless the dome is a complete hemisphere. Another geometric shape in which all rings in the dome are concentric is possible: this geometric shape is often used in aluminum geodesic dome roof d roofs. Concentric geometry has obvious advantages.

 

However, this design is structurally not as effective as the first design. Another geometric shape often used in aluminum geodesic dome roof d roofs is a combination of the two or more. In this design, there is a transition from the first geometric shape to a concentric base

Sounded throughout the dome or several rings of the dome.

 

This design is stiffer than the first design and has less variation in beam length. Due to other geometric constraints, the final geometric shape of the dome may be further modified. These constraints may determine the final geometry. The most common are:

1. Width of aluminum coil. The shortest height of the panel must be smaller than the coil width.

2. The light beams at the hub interfere. There must be enough space between adjacent beams

Connect at the hub.

3. Load and structural constraints.

 

The engineering problem of the final geometry of the aluminum geodesic dome is the same as many other engineering problems because it consists of various design constraints.

Dome components The aluminum geodesic dome is a relatively simple product, with only 3 main manufacturing components and a few secondary components. The main components account for most of the dome material and manufacturing costs. The secondary component is the components needed to complete the dome, but usually the total cost of these components does not exceed 20% of the total cost of the ball machine. The 3 main components on the dome are beams, connecting hubs and panels. Common secondary components are slats, brackets, hub covers, waterproof panels, ventilation holes, manholes, skylights, etc.

 

Beam or pillar

The dome beam is made of extruded aluminum alloy. Aluminum alloys have the same minimum strength characteristics. Aluminum alloy is a relatively new alloy. The main advantage is better completion, less sensitivity to the time frame and quenching after extrusion. In most cases, air quenching can be used instead of water quenching to size. Finally, its cost is a bit lower, mainly because it is easier to quench the extruder. The protruding part of the top of the beam must be milled or cut back so that the beam can be bolted to the connecting hub. This aluminum geodesic dome roof beam extrusion is typical. Note that the protrusions above are the best. The protrusions are attachments to the dome panels and slats. The slats hold the dome panels in place and connect the beams with ¼” trefoil screws in the center slot. The flange stiffeners at the end of each flange are a typical thin-walled beam extrusion. The flange stiffeners increase the allowable compression in the thin wall And the curved shape is about 20-25%. They also increase the weak axis moment of inertia, section modulus and radius of gyration without increasing the width of the beam. Thicker shapes do not need them.

 

Hub

 

The hub is the junction of the connecting beams. The hub is a circular plate with a punched center hole, which is used to place on the forming mold to press out the required angle of the plate. The center hole on the top hub is used to install the hub cover. There are four possible common. Aluminum materials that can be used for wheel hubs: extruded flat steel and hot-rolled plates.
