Attaching Wall Mounted Bookshelf/Cabinet

I'm planning a wall cabinet with shelving above my desk. My question is what size attachment hardware and how many. The wall it will be attached to is concrete filled hollow block. The cabinet will be 8" long 46" high x 12" deep. It will be three shelves with a center opening to hold a 32" TV. Construction will be 3/4" plywood wit a 1/2" plywood back, and of course solid face boards and moldings. This will take two sheets of the 3/4" ply and one sheet of 1/2" ply, plus the weight of the 3/4" face boards. It will also be supporting quite a few books. The largest shelf span will be 30"~ but with being attached to the back plywood and a front face board, sagging should not be an issue. I was thinking of lag shields but concerned how to hide the heads. Here, many drill holes and insert wood plug and just nail and glue. Other ideas on attachment hardware and how many?

Too bad the blocks are concrete filled as toggle bolts would be perfect.


There are numerous "expansion bolts for concrete" on the market. Most of these would be good. I would not use wood plugs. Granted that most of the load will be vertical, I still want something that is more mechanically tight in the hole.

Thanks George. If these blocks were made like in the US I would agree. However, here the blocks are somewhat soft and easily crumble. They are used more as a filler and are not load supporting. That is why they fill them with concrete.

Kitchen cabinets are hung from hooked brackets and these are supposed to hold a load of 150 kgs. Calculate the total weight to be supported. I would put a batten below the case to give further support. I used to do this anyway as it made working single handed more easy.
We had a bookcase put up by a company. I will see if I can post a pic sometime.

Then your best procedure is to use long bolts and drill into the solid concrete.

You can fasten French cleats to the wall- that will hide the heads.

The cabinet will be 8" long
Sounds rather small. I'm guessing you meant feet?

Use tapcons long enough to screw into the concrete-filled voids. I think a couple of those holding on cleats like this pic should be enough. Probably a cleat near the top and bottom of the cabinets. Maybe a screw every 16"? If it is 8' long then I think every 16" would be more than enough if not overkill. I don't know what the final weight limit will be.

phaelax,
Lol, yes 8' long. As for the weight with two sheets 3/4" plywood and 1/2" plywood and added trim boards that alone could weigh over 200 pounds. Then add books and some display "stuff" and I'm guessing the total weight could approach the 400 pound mark. Thanks much for your thoughts.

I used Tapcon screws to hold a shelf. They went into cinder block.

Well as you read above hooked bolts work but to be more safe expansions bolts can also help.

I would use something like this long enough to penetrate into the filled concrete:

Thanks Frank, That is one of the options I was considering if I can locate some long enough here. I have used shorter ones on other projects with great results. As of now the best I can find is long lag shields which I also have had good results. With the suggestions here I am now thinking of a batten under the shelf held in place with lag shields. I make a cover trim board to hide the bold heads. Additional lag shields will be placed on the upper inside spaced 16" apart and again some molding to hide the bolt heads. Thanks to everyone for all the suggestions.
