"Aluminum trusses", steel-like structures used in lighting and speaker installations. Sound House has a large lineup of trusses in different shapes and sizes, which can be used for various purposes.
Most importantly, triangular trusses are not available at shops other than Sound House. Sharp looks make them different from square trusses, and are recommended for “objet”, event booths, and store displays.
The most common inquiry we get about such triangular trusses is:
"There is a variety of corner parts…which ones should I choose?!"
The flexibility to create a variety of shapes using corner parts is one forte of Sound House truss systems. However, when it comes to the corner parts for triangular trusses, there is an enormous number of parts, upward and downward, and right and left, and so on. Also, even if you contact us, it is difficult to advise orally or in text format alone. That's why in this article, I will explain how to select the right triangular truss corner parts!
This time, we will use the example of "triangular truss box set type".
In this set, two different parts are used for corners, theT"TRUSS3 / L31 (L31)" and the"TRUSS3 / L32 (L32)"
What is the difference between these two types? Can the set be assembled if I make the wrong choice? are the questions that will come up, and the answer is, "You can assemble the set using either the L31 or the L32 alone".
So what is the difference? "Pillar orientation" is different.
First, here is an image of the combination of L31 and L32. The red triangles indicate the orientation of the pillar.
You can see that the triangle bases are aligned on the wider front side of the structure.
The next image uses only the L31 for all four corners
The direction of the pillars varies from corner to corner. Of course, some people may prefer this, and there is almost no difference in structural strength.
If you change the corners where L31 and L32 are used, the result looks like this.
You can also align the base of the triangle to the short side of the box. Either way, you will need to use two corner parts, both the L31 and the L32, to align the orientation of the pillars.
It may not be a big problem just to construct a truss that is being used as an “objet” on its own. However, it’s easier to work with if the bottom is aligned when you want to display a tapestry or a signboard at an event booth. The same applies when using the set for a stage and hanging a backdrop.
Something like this.
If the bottom is aligned...
The backdrop can be hung like this, but if the bottom is not aligned…
…the backdrop will be slightly shifted to one side. This is not recommended if you want to bring the logo, band name, and so on exactly in the middle. If you are considering using it on a stage, we recommend combining the L31 and L32!
So this time, I introduced the different corner parts and how to choose them, using a very simple example. I hope that this article has eliminated any confusion!
