Steel H beam UC254x254x89 is been erected and leveled and grouted.
Step 1. Clean area were you need to grout well.
Step 2. Put a timber covering around the area.. lets say 50mm bigger
Step 3. lift the H beam and put it on the bolts/ anchore rods and check if it fits.
Step 4.. once your sure on it.. keep the beam on a side bit far from the work area.. lets say about 2 meters, so that you can have space for mixing the grout and other preprations.
Step 5. Mix the non shrink grouting with water untill it mix well.. im not gonna post a pic of brand or packet.. no advertising 😋
Step 6. Pour the mix on top of the prepared area
Step 7. Put the steel H beam on top. But before that make sure to put a bitumen sheet on top.
Step 8. Observe with level instrument for this case they used a Sprite level.
9. Than tight the nuts until level shows its buble is to level.
Tip; if you look at the above vedio, you will notice that they have put a steel packing or steel sim or steel packer under the H beam steel column. This is that when the grouting set it may squeez the whole grout out.. and it will make it easy to level.
Above represents the mechanical door that open it self without power from any electric or disel motor... once the car gets on the platform the weight of the car lowers the ramp and which will pull the connection rod down which will make the cross door open.
below is cad drawing which illustrate the design.
white lines show how it will be open when the car go on top of the yellow lines, yellow lines represents the ramp which the car will pass over. the green line shows the tension rod which will pull the pink lines making it white lines.
