Hammer-in dowels: in the Union, the technology is bent. But now Europe makes money on it
Hello, friends.
A friend called me the other day. He's a monolith. We talked with him about fasteners. It turns out that they still attach the formwork to the concrete base with Soviet assembly guns of the PC-84 type. And such sadness, longing took me. Hasn't our science made one step forward over the decades?
If someone has not come across, a few words about the PC-84 powder assembly gun. At one time it was a cool thing. You load a steel plug with a cartridge. I pulled the trigger and the part was shot to a concrete, brick and even steel base. No electricity and tedious hammer drilling. And most importantly, reliably - you can't tear it off ..
In Soviet times, there was no price for this instrument. At all the objects where the electricity had not yet been supplied, only the clapping of this pistol was heard. In the garages, the men shot them all they could. The dowel from this pistol pierced a steel corner or channel and, like oil, entered a concrete wall.
This, of course, is all great, but time goes by. In the west, they came up with multi-charge pneumatic construction pistols. No need to reload ammo after every shot. Everything is powered by a compressed gas cylinder. The performance of pistols is 1,000 rounds per hour and this is not the limit.
For comparison, to make one attachment point to the Soviet PC-84, you need:
- insert dowel
- click it all the way with the ramrod
- open the gun
- load cartridge
- close the gun
- and only then shoot.
Friends, why did a seemingly good technology die in the bud in the Soviet Union? These PC-84 assembly pistols are still produced in almost the same form. Where is the progress?
I accidentally learned that this tool is still being used from a conversation with a friend. Usually on a construction site, if the fitters have already outgrown the hammer drill, they use an air gun. The single-shot powder pistol, in my opinion, is a relic of the past.
Or maybe I don't understand something in this life and the Soviet development is cooler than modern analogues? Let's say, like a Kalashnikov assault rifle, better than which it is difficult to invent something. At least a friend explained that there is simply no money for normal equipment. It all sounds sad - the builders have no money. Who has them then?
