The construction gun is an indispensable tool widely used in many construction and installation works. In fact, this is a convenient, and most importantly, a quick alternative to drilling holes in high-strength bases for various fasteners. All you have to do is pull the trigger to drive the nail into the material.
Features and scope
The gun is designed for driving dowel-nails into concrete, reinforced concrete, brick, stone, steel and other hard surfaces.
In appearance, the tool looks like an ordinary pistol or a small jackhammer. It is used in the installation of electrical and ventilation equipment, various pipelines, in roofing, plumbing and many other construction and installation works. Its principle of operation is based on the use of special cartridges, the sleeves of which are painted in a different color, indicating the level of charge.
The dowel gun is quite easy to use. Thanks towith its maneuverability (it does not need a power source), it allows installation of fasteners in the most inaccessible places, regardless of any weather conditions.
Operation principle
All manipulations using this tool are performed using direct mounting technology. The construction gun for dowels works very simply: you just need to pull the trigger, and in a couple of seconds you will get the desired result - the dowel is aimed at the base reliably and very firmly. This is due to the fact that during the shot, passing through the "barrel" of the gun, the dowel is very hot due to the powder mass in the cartridge.
Pros and cons
Working with this gun is dangerous and difficult in some cases, for example, if it is performed at high altitude or in labor-intensive processes. Moreover, in any case, physical strength and skill are required.
But these moments do not detract from the advantages that a construction pistol has:
- strength and reliability of fasteners;
- high work productivity;
- possibility of installation in hard-to-reach places.
A significant disadvantage is the high cost of the tool. But once you buy it, you can use it for years to come.
Types of construction guns
Depending on which energy source is used, the gun is divided into three types:
- pneumatic;
- gas;
- gunpowder.
Each of these species haslock to prevent accidental firing. This reduces the risk of injury and ensures safe use of the tool.
Air construction gun is one of the most popular types of these tools. Its operation requires compressed air, which is supplied from a central compressor or cylinders. Using this tool, you can drive staples during the installation of sound and waterproofing of the roof, the installation of stretch ceilings, as well as during the fastening of various sheet and roll materials, fiberboard and chipboard.
Gas construction pistol is a non-cartridged tool. It is equipped with a chamber where butane-propane gases are burned. As a result of this process, a blast wave is generated, due to which the dowel is pushed out and penetrates into the mounting surface. The difference between such tools is that they are suitable for working with any grounds.
A construction gunpowder gun is a device loaded with special cartridges. Their design is arranged in such a way that a blow to the dowel produces a striker set in motion by the energy of a powder charge.
Most often these guns are used in work with brick, concrete and reinforced concrete surfaces.
Features of the gunpowder tool
This gun belongs to automatic tools, so it is advisable to use it for a large amount of construction and installation work. Its design is reliable and convenient. Thanks to its device, a through chamber of the basecompletely eliminated, since the dowel head stops moving when the striker stops.
The gunpowder construction gun has a number of advantages over other types:
- using a wide variety of nails;
- possibility to work with large dowels;
- creating a high power shot;
- ensuring high-strength adhesion of fasteners to the base;
- lack of additional equipment;
- compact and relatively light weight of the tool itself.
Compliance with the rules of operation
Instructions for use are attached to any type of construction guns. Before work, it is required to study it in detail and strictly observe all points. The main ones relate to stringent requirements for ensuring tight contact between the “barrel” of the tool and the mounting surface, as well as accurate selection of cartridges. Indeed, in most cases it is impossible to fire a shot without pressure on the fastener part, and the penetration depth of the dowel directly depends on the strength of the powder charge of the selected cartridge.
Precautions
When using a nail gun, you need to use personal protective equipment:
- construction helmet;
- safety goggles or visor;
- special earmuffs (Group A);
- gloves.
Prevention measures
A pistol chambered for building cartridges is not a child's toy. Therefore, it is necessary to clearlyfollow the instructions for its operation, storage and prevention. This will ensure not only safe and long-term operation, but will also make it possible to avoid breakage of expensive tools.
The main preventive measures are as follows:
- use only branded factory-made cartridges;
- storage of cartridges separately from the pistol itself and consumable dowels;
- periodic inspection of the store to detect foreign objects that can get there when changing clips or loading nails;
- periodic disassembly and cleaning of the internal parts of the pistol after the number of shots indicated in the instructions.
Construction guns for different types of work
In addition to nail guns for driving dowels, there are also various types of these tools that can be used to carry out a wide range of construction work.
These include guns used to apply sealant, glue or grout.
A caulking gun is a tool that extrudes a compound designed to seal something out of cartridges. Its work is based on the movement of the piston, which, acting on the bottom of the cartridge, squeezes out a certain amount of sealant.
According to the type of compartments in which the cartridges are located, such pistols are leaf and frame, and it is the latter that are mostpopular. They hold sealant containers well.
Depending on the method of extrusion of the composition, these tools are:
- battery, the advantage of which is autonomy;
- electric, which operate from the network and are designed to work with different cartridges;
- pneumatic.
In the latter version, the material is extruded under the action of air when the handle is pressed. As a rule, these guns have an ergonomic design and various devices for controlling and limiting the output of sealant, due to which it is very convenient to work with them.
The construction glue gun has a very simple principle of operation: a stick with glue is placed in a metal chamber, where it is heated by a thermocouple connected to the mains, and after pressing the trigger, molten glue is squeezed out through the nozzle.
Using this gun you can glue plastic, glass, metal, wood or leather surfaces, join strips of linoleum or fiberboard sheets, fix shoes or assemble broken porcelain, seal, decorate or model anything.
The construction grout gun is an indispensable tool for grouting brickwork, clinker and other types of ceramic tiles. It reduces material wastage, maintains a clean work surface and accurately fills joints without voids or air bubbles.
Using separate viewsof these guns, you can not only facilitate the implementation of various construction and installation works, but also carry them out quickly and efficiently.
