How to Reinforce Bookshelf

Have you ever noticed that when the shelf, or any furniture for that matter, gets old, it starts to sag in the middle and falls apart over time? Don’t worry, though, because there is an easy way to fix this problem! All you need are some screws and a drill! 

How to Reinforce Bookshelf

If your Bookshelf is sagging in the middle, then all you need to do is drill holes into the top of each board on either side of where they meet together with the point where it bows. Then take three screws, one for each hole, and screw them through the board.

This will make sure that your Bookshelf doesn’t fall apart anymore. You can also use nails, but they may not be as effective. So, this article is for you. You will learn how to reinforce Bookshelf with just one simple trick!

Step to Follow on How to Reinforce Bookshelf

Step One: Determine Bookshelf Type

There are several different types of bookshelves. However, each one needs to be reinforced for safety reasons if the books are heavy. They should all have some storage space built in them, whether it is big or small. They require some shelves, and the frames should all be metal.

Determine Bookshelf Type

Thin Bookshelves are the most common and are also the easiest to reinforce. They are usually small with one or two shelves but can hold an average load of books. These are perfect for offices, kids’ rooms, and they can even be placed in the kitchen. Medium Bookshelves are for larger areas that require more storage space or multiple surfaces.

Step Two: Remove the Shelf

Remove all the shelving carefully. This will keep the Bookshelf from falling apart when it is being reinforced. Set up one bookcase next to another for easier work. If the shelves are not removable, remove them with a crowbar or chisel by loosening them slowly and pulling them out bit by bit until they are all out.

Soak the shelves in water for an hour if they are too large to remove. This will help the wood expand and soften to make removal easier. Next, tilt the Bookshelf toward one end to loosen the shelves. If the Bookshelf is made of wood, use a crowbar to pry it off slowly. Be careful not to catch or rip the nails out of the frame.

Step Three: Reinforce a Thin Bookshelf.

For this type of shelf, use metal brackets and screws to reinforce each corner with two brackets on each shelf support. The brackets should be spaced on 24″ centers. Use screws with a head large enough to hold the bracket on tightly. Countersink each screw on the back of the shelf at least 1/8 of an inch deep.

Reinforce Each Corner With Two Brackets

Be sure not to drive them into or through any cross members by keeping them away from areas already damaged. Proceed by placing the new brackets on the support posts. If there are no cross members, use four screws per bracket.

Step Four: Reinforce a Medium Bookshelf.

If the Bookshelf is large, it will need more reinforcement than just two screw brackets. Choose an appropriate cross support beam to attach the shelf too. Use screws that are the correct size to be threaded through the shelf and screw into the beam.

Attach one support near each corner of the shelf. Screws should not penetrate more than 3/4 of an inch into the beam. Be sure there is enough space between each to not interfere with any other cross members or supports. This is especially crucial if the shelf will be holding a lot of weight.

Step Five: Replace the Shelf.

Choose either to attach new shelves or reuse old ones. Attach them with screws through the supports at each corner. Be sure to use an equal number of screws on each support so the shelf won’t fall apart. Press down hard on a corner to see if it will hold your weight before adding any books.

Step Six: Reattaching the Shelf

This can be tricky. If possible, choose a corner, to begin with so it is squared up properly once attached. Then, carefully place the shelf on the support beam and align all four corners equally before screwing into the supports.

Each corner must have an equal amount of screws, or they will not hold together properly. Use as many screws as is needed to hold the shelf together once it is fully loaded with books. If the old shelves have been soaked, allow them to dry completely before using, or they might crack or split from being wet and then being allowed to dry out again.

Step Seven: Enjoy Your New Bookshelf!

Now that the shelf is wholly reinforced, enjoy its sturdiness and strength! Be careful when loading it with any heavy items to avoid injuries. Your Bookshelf should be able to safely house many types of objects, depending on their size.

Enjoy Your New Bookshelf!

Do not overload it with too many large, heavy objects if it is a thin bookshelf. If you are using old shelves soaked, be careful to dry evenly so they do not crack or split. Please make sure each shelf is balanced and equally spaced apart before loading them up with many books.
