Often in the construction and repair there is a need to attach any materials to the building foundations. An excellent replacement for manual installation is the mounting gun. It is customary to distinguish between mounting guns powder, gas and pneumatic (staple guns, for example, a construction stapler).
The powder gun functions thanks to the energy of expanding powder gases. With it, a dowel-nail is driven into a metal, concrete, expanded clay concrete and brick foundation. For stationary fixation, nails with a classic hat are used. For installation of structures to be dismantled - dowels-screws. Such a
construction gun does not need electricity and therefore stands out from other tools.
With its help it is possible to carry out installation work away from electricity, for example, in a house under construction, on the street, etc. Energy is produced due to non-remote cartridges with charges of different capacities. The strength of each charge depends on the type of building base. Cartridges, depending on power, are divided into seven groups, and each group is painted in a separate color. To have such an assembly gun, you need the appropriate permission. Caring for it comes down to cleaning off powder deposits, but it needs to be done quite often. The fragility of the pistol and piston, as well as the difficult selection of charge power are serious disadvantages of this type of tool.
The gas mounting gun has a simple principle of operation. A gas mixture (propane-butane) is supplied from the cylinder to the combustion chamber. There, with the help of an electric fan, an air-gas explosive mixture is formed. The battery produces a spark that sets it on fire, and a mini-explosion occurs.
The kinetic energy resulting from this explosion pushes the piston with the force necessary to drive a nail. In this case, the surface density practically does not play a role. However, the strength of fastening depends on it. So, in a wooden base the nail will sit less firmly than in a metal one. The advantage of such an apparatus, undoubtedly, is that with its help it is possible to carry out sighting to steel. Consumables in the gas mounting gun are small-caliber nails that have undergone special heat treatment. Also, for each individual type of material, nails are selected in a certain series. It’s easy to take care of a gas pistol: you only need to clean and lubricate 30 thousand rounds of it once. Such pistols of various modifications are produced, which allows them to be widely used for electrical installation, for roofing and
carpentry, for shooting drywall guides.
The assembly gun is produced in a wide assortment by various companies. Among them are Ramset, BeA, Hilti, SPIT, Bosch, Skil, Paslode, Tula Arms Plant OJSC and others. Model prices vary depending on the functional purpose and type of tool and range from 2 thousand rubles (staple-proof household) to 30 thousand rubles (gas gun for electricians). Therefore, it is important to determine exactly before which purchase an assembly gun is purchased and by whom it will be used.
