Rafter Frame Tent

The best way to explain what to look for during an inspection is to understand the installation process that a tent rental company should follow using the Manufacturer’s Installation Guidelines. Our video describes this process, and so we shall begin with a show and tell installation setup for a rafter type frame. Using your mouse pointer click on the arrow inside the circle and view the video.

Let’s put the popcorn down and begin by comparing the video instruction to the next photo.

Rafter Frame Tent

In this slide our illustration of a frame inspection begins by comparing the video installation with the Frame Tent photo. Do you notice the flaws in the picture? One noticeable defect is the middle side poles are missing adequate anchorage. You cannot even say it is securely anchored because there is nothing there. The display may have caused the anchoring problem, but if you reverse the same photo, the middle side poles are not attached to an anchor rope or webbing. Is it secure? Yes, after you lower the wind load number to 15 mph. The fix is to add a cable connected to a stake driven into the ground or a concrete block for ballasting that is sufficient to maintain wind load stress on the center and side poles.

Center Support Frame Tent

In our next video, we have a center support frame tent, also referred to as a high peak frame tent. First view the video. As with the rafter frame tent, we are going to use the video as a reference and look for any flaws in the installation….

OK are Milk Duds are finished we begin with comparing the video Center Frame Support instruction to the next photo.

Center Support Frame Tents - High Peak Frame

Our example has two Center Frame Tents. The first photo demonstrates ballasting and the second photo shows anchoring with stakes. Comparing the two photos and the video demonstration where do you see infractions and how can we fix the violations? The first photo on the left is missing ballasting on all of the side poles. The solution is to add more ballasting or set a lower wind speed for evacuation. In the photo on the right, we finally have a frame tent that is staked according to the Manufacturers Installation Guidelines, and it appears the rest of the installation is good to go….

Track Frame Tent

Branded with various manufacturers names a track frame ranges in sizes between 20 and 50 feet wide. The Track frame tent and a clear span both use a track railing system and Keder style tops and side walls, but the Track Frame anchorage solution still utilizes webs and ratchets that are attached to stakes or concrete blocks.  OK, let’s set the popcorn down and move on to the next slide. We will begin our feature attraction with the Track Frame system video installation.

Enough is enough with the movie stuff we begin by comparing the video Center Support Frame Tent instruction to the next photo.

Track Frame Tents

Frequently Track frame systems are engineered frame tent structures that provide exceptional performance in both short-term and seasonal applications. The major tent companies certify the Track Frame System and follow the guidelines of ASCE 7-02 included with their engineering documentation. For longer-term installation, it is imperative that you follow the manufacturers engineering guidelines. Replacing pins with bolts and crisscrossing cabling between bays are examples of long-term installations. Site layout, anchoring, and squaring carry the same value and integrity in all of our frame tent examples.

Frame Tent Quiz

But hold on before we continue with our Inspection Course we are going to take a short quiz. Move your mouse pointer and click on the “Pop Quiz” image.
However, before we close out our inspection, we need to look at a significant aspect, which is how is our tent attached to Mother Earth.
