Guide to Hanging Fixtures on Lightweight Concrete Walls

Can autoclaved aerated concrete hang things on:

Autoclaved aerated concrete is a new construction material so few people have access to it. So many interesting questions are raised around this type of material. Among them, hanging things with hooks is of great interest. Some people believe that because AAC blocks and ALC wall panels have many air holes, they have a porous structure. It is impossible to catch a millet and if it does, it can only hang light items.

For that reason, HASS set up a small test to demonstrate the ability of this material to hang things.

Types of screws and sockets suitable for AAC materials:

Before starting the experiment, we will learn more about the general concepts when hanging heavy objects on the wall.

To hang hooks or nails, people often use screws and clamps to firmly fix them on the surface of a concrete brick wall. And for AAC tiles and ALC wall panels, you can completely choose between regular switches or specialized switches to use. However, please ask the supplier for advice so you can use the correct screws and specialized brackets to get the best results when choosing screws and brackets for hanging clothes.

Extraction force of screw screwed into AAC:

When a screw, clamp+screw or anchor bolt is driven into the wall material, it will adhere to the material through friction. (born from the expansion of sockets and bolts). To pull a screw out of the wall, you need a pull-out force.

Screw extraction force depends on the following factors:

a) Diameter and length of screw. The larger and longer the screw, the greater the extraction force

b) Shape of the millet

c) Compressive strength of AAC wall material. The higher the intensity level, the greater the extraction force

d) Construction techniques. If the hole diameter is larger than the plug diameter, the extraction force will be significantly reduced

Video of experiment on autoclaved aerated concrete brick wall hanging heavy objects:

Video 1: Installing switches on AAC blocks.

Fixing bricks onto AAC blocks shows that the tiny air holes do not affect the adhesion of bricks and the bricks are not as porous as rumored.

Video 2: Bearing test on 1 point of AAC blocks:

HASS used cement bags weighing nearly 50kg/bag placed on a pallet hanging on a pallet at one point. As you can see, even though you put up 4 bags equivalent to 200kg. The clamp has not yet come off and is still firmly attached to the hanging point.

Video 3: Load-bearing test using electric brackets on AAC blocks

Same experiment as before this time with 2 e ke racks along with 4 millet switches. The sturdiness of the stand is much improved. Although in the video HASS only tested with 4 bags of cement equivalent to 200kg, in reality with these 2 keel brackets, the brick wall can withstand about 800kg thanks to 4 clamping points.

In addition, HASS also tried wearing a 50 kg bag of cement to create a small anchor bolt. The result still succeeded all expectations when the hanger still maintained its shape without moving even after a long time.

Video 4: Not just used to hang things.

Because of such good bearing capacity, this will be another suggestion to apply the bearing capacity of ultra-AAC lightweight blocks. You won't be able to resist exercising when you have a crossbar in your home.

Conclusion:

With our tests, the ability of autoclaved aerated concrete to hang heavy objects has been clarified, removing all doubts. Not only is it compatible with many popular screws and sockets on the market, the strength of the ultra-AAC lightweight block has been shown to be amazing. With just a few simple steps, you can have an extremely convenient and sturdy hanger on your autoclaved aerated concrete brick wall. HASS hopes that after this article you will have more interesting knowledge about drilling and nailing to hang things on ALC panel walls to make your daily life more convenient.
