Everyone understands what a cog is, but what is a tongue and groove?

We have known these famous cartoon characters since childhood - Vintik and Shpuntik. And their names seem to be simple and understandable. In fact, there are no mistakes with just the name of one hero. Everyone knows what a cog is. Many people make mistakes with tongue and groove. Although it’s not difficult to figure out what it is.

Everyone knows Vintik, but what is Shpuntik?

Erroneous name explanation

Most of us, hearing the name of our friend Vintik, imagine some kind of metal object. Most often people think of a nut. And they are even sure that this name was invented only because the cartoon character is male. And if the second main character of an animated film was a girl, she would probably be called “gadget.” That is why many people still imagine a tongue in the form of a nut or a similar iron object.

What is tongue and groove

what is tongue and groove

In fact, the name of the cartoon character is a diminutive form of the word “pile”. This is a certain type of fastening that is used in metal, wood or even plastic parts. But it in no way resembles a screw or a nut.

Wood detail element

The word "tongue" means protruding part on a wooden product, which is intended for fastening. It is inserted into the groove, securing the joints without the use of metal fasteners and additional equipment.

fastening

Reference. Dowel fastenings are used in wooden furniture or flooring.

The protruding part of the wooden product, located on one side of the future structure, fits into a groove or hole on the other side of the product. This way you get a solid piece that is tightly held together and lasts a long time without breaking. In some cases, you have to beat it with a mallet to make it fit tightly. In most modern materials, the protrusion easily fits into a pre-prepared groove and falls into its intended place.

Application

An example would be wooden stools made according to old designs. The legs and seat were held together by protruding small wooden “pins” on the legs of the chair. They were inserted into holes pre-made on the back of the seat. And they beat them with a mallet so that they would sit firmly.

application

A modern example of the use of steel floor coverings (floorboards, laminate) or PVC panels for finishing walls inside the house. They also have protrusions and are connected to each other using them without the use of any third-party fasteners made of metal or plastic.

Larsen metal tongue and groove

This mount is a metal “lock” that has good waterproofing properties..

Larsen tongue and groove

Reference. Larsen sheet piles are widely used in small and large-scale construction.

Larsen products come three types:

  • U-shaped;
  • Z-shaped;
  • S-shaped.

They represent metal profile with reliable Larsen locks on the edges. They are mounted in two available ways: using vibration immersion or using static indentation installations.

Peculiarity

Features of Larsen tongue and groove

Thanks to the additional use of various mastics, varnishes and other compounds with water-repellent properties, The joints are absolutely impermeable to moisture.

The uniqueness of these fastenings is possibility of their repeated use. Such profiles can be easily rented. And after carrying out the necessary measures, remove it and return it to the landlord. This does not affect their performance in the future and does not spoil their quality characteristics.

Thus, the cartoon shown to us in childhood is misleading and does not give a clear idea of ​​who Shpuntik is. Although the tongue itself is very popular among professionals.

Comments and feedback:

The author has a brain twist. This is a completely different tongue, used in the production of wooden barrels, and is a wooden nail, cork, plug.

The one who composed the fairy tale was apparently guided more by word formation than by naturalism of meaning.
Most likely he has a SHKANTIK on his tongue - this is a pin made of any material that has neither a point nor a cap. But the diminutive e from shkantik either did not occur to him or seemed silent. So he chose SHPUNTIK. Vintik and Shpuntik rhyme perfectly. unlike Vintik and Shkantik.

Somehow, from the very first moment of “acquaintance” with these characters, I decided that since Vintik and Shpuntik are jacks of all trades, then one of them should be a mechanic, and the second a joiner (or carpenter). Since Vintik’s “name” clearly hinted at a “metal worker,” I came to the conclusion that “tongue” is something from carpentry, carpentry—in general, “wooden” work.As it turned out later, I was not mistaken in my assumption.

Tongue in German is plug. And Tsigel is a brick. There's no need to straighten people's minds

The boards were fastened together along their length with “tongues” - small wooden cylinders. Something like this. Sincerely.

The tongue and groove had absolutely nothing to do with the wood in the cartoon, don’t fool anyone, he didn’t build anything tongue-and-groove there, and we didn’t use it much in wood in those days, simple planed boards were in short supply... The tongue-and-groove was used in engines, uh
electric, gasoline... To connect the shaft with the torque element... This is the so-called protruding part... Vitik and Shpuntik were engaged in mechanics and were not carpenters

author
Dmitriy

And the author did not have any verbal diarrhea... The crankshaft and generator on old engines were connected to transmit torque with a tongue..

The tongue is just the part that doesn’t protrude. The protruding part is called the ridge and the tongue is on the other side.

vinTIK and dowel..and vinTIK and dowel rhyme the same!! look at the identical endings!!!

To connect the shaft to the torque element... This part is called a KEY and it is a GIRL!

Also, so that the part does not fall off the shaft, during rotation, a cotter pin is inserted through the through hole. Then they straightened his mustache so that he wouldn’t fall out!

I once figured out how to make a disk for pressing in a cabbage tank. I cut a circle out of a wide board and attached a board on top.It is undesirable to use iron nails, screws, as I thought. I drilled 4 holes, cut out 4 chopsticks with a diameter of 10mm and hammered them in. By the way, nothing has fallen apart for more than 12 years. I didn’t know the decoding of the name Shpuntik, Thanks TS for the article Can they be called tongues? By the way, for oppression I use a hefty piece of rock, with an amethyst druse on top. Both beautiful and practical. Usually amethyst flaunts in the wall for the time being.

The tongue is also a plug for the barrel. (beer or wine).

Also, metal piles with a lock are called sheet piles. They protect the place where concrete is poured in the riverbed during the construction of a bridge.

For Barinov. In German, “plug” is Spund through D. And a small cylinder is a dowel. Before you get smart and write something, you need to know a little bit about the hardware.

for Alexey. You have confused a tongue and groove with a key. It is this that mechanically connects the shaft and the torque element.

author
Vladislav

for Dmitry. The crankshaft was connected to the generator mechanically using a KEY.

author
Vladislav

A dowel is the same screw, only without a head and is inserted into a groove instead of a dowel in sliding joints. Not to be confused with a pin that is firmly attached.
In long wooden joints, tongue and groove are called tongue and groove, and only one way and nothing else.

The most valuable thing in your comment is the cylinder... Can you guess what to teach???

Dmitriy Sergeevich

For Vladislav, “for Alexey. You have confused a tongue and groove with a key. It is this that mechanically connects the shaft and the torque element.” In my opinion, I wrote that the KEY transmits torque.
