These are suggested for overhead applications. Can they be used for installing toilet flange to concrete sub floor?

Asked by Jb July 31, 2016
1
Answer

Yes, you can use these anchor in sub floor applications. With a drop-in anchor you will have to use a threaded rod and a nut that will protrude. Please use a 3/8" concrete drill bit and the right setting tool. Another option is using Tapcon concrete screw anchors. You don't need a setting tool to install Tapcons and they are removable. Please contact technical service at 800-899-7890 if you have additional questions.

I want to anchor down a portable Gazebo to my concrete patio. will this hold it down if we get high winds

Asked by chuck October 7, 2014
1
Answer

Without more design details on your Gazebo it is impossible to determine. A 100 MPH wind will press about 40 lbs/sqft on the projected area of the gazebo. If the vertical center of this projected area is as high as the gazebo is wide the pressure would be translated to uplift on the windward side. One half the weight of the gazebo would be subtracted from this uplift. You will then need two times enough anchors to counter the remaining uplift by 1.5 times for safety. I would suggest using 1/2 inch anchors evenly spaced around the gazebo. Redhead will have the design pullout strength of the anchors on there web site.

These were simple to install after drilling a 5/8 hole in the concrete. It is important to hammer the plunger straight down or the anchor will tilt making it difficult to screw in the threaded rod. There is also a special tool that is used to hammer the plunger so it spreads out the anchor.

Red Head products are always excellent. Drop-In anchors are excellent for threaded rod and make it possible to cut the rod at the length needed for each hole. Bolts are great when the project is repetitive; but, make it necessary to cut bolts off or add washers under the bolt if you do not get every hole drilled at the correct depth.
