Construction gun and its application

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 substrates for various fasteners. You just need to pull the trigger so that the nail enters the thickness of the material.

Features and scope

The construction gun is designed for clogging dowel-nails in concrete, reinforced concrete, brick, stone, steel and other hard surfaces.

In appearance, the tool is similar to an ordinary gun or a small sized jackhammer. It is used for the installation of electrical and ventilation equipment, various pipelines, for roofing, sanitary and many other construction and installation works. The principle of its operation is based on the use of special cartridges, the sleeves of which are colored in different colors, indicating the level of charge.

The construction gun for dowels is quite simple to use. Due to its maneuverability (it does not need a source of energy), it provides installation of fasteners in the most inaccessible places, regardless of any weather conditions.

Operating principle

All manipulations with the use of this tool are performed using direct editing technology. The construction pistol for dowels works very simply: you just need to pull the trigger, and after a couple of seconds you will get the desired result - the dowel shoots to the base reliably and very firmly. This is due to the fact that during the shot, passing through the "trunk" of the gun, the dowel is very hot due to the propellant mass in the cartridge.

Advantages and disadvantages

Working with this gun in some cases is dangerous and difficult, for example, if it is performed at high altitude or in time-consuming processes. And in any case requires the presence of physical strength and skill.

But these moments do not detract from the merits of a construction gun:

• Strength and reliability of fasteners;
• High productivity of works;
• The possibility of mounting in hard-to-reach places.

A significant disadvantage is the high cost of the instrument. But once you have purchased it, you can use it for many years.

Types of construction guns

Depending on which energy source is used, the gun is divided into three types:

• pneumatic;
• gas;
• Powder.

Each of these types has a lock, protecting from an accidental shot. This reduces the risk of injury by ensuring safe use of the tool.

Pneumatic construction gun is referred to the most popular kind of these tools. For its operation, compressed air is required, which is supplied from a central compressor or cylinders. Using this tool, clamps can be clogged during installation of sound and waterproofing of the roof, installation of tension ceilings, as well as during the fastening of various sheet and roll materials, fiberboard and chipboard.

A gas construction gun refers to no-dust tools. It is equipped with a chamber where butane-propane gases burn. As a result of this process, an explosive wave arises, due to which the dowel is pushed out and penetrates into the mounting surface. The difference between these tools is that they are suitable for working with any bases.

Pistol building powder is a device, loaded with special cartridges. Their design is arranged in such a way that a blow to the dowel produces a firing pin driven by the energy of the powder charge.

Most often these pistols are used in works with brick, concrete and reinforced concrete surfaces.

Powder Tool Features

This gun refers 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, the through lumbago of the base is completely eliminated, since the head of the dowel stops moving when the striker stops.

The powder gun has several advantages over other types:

• Use of a large range of nails;
• The possibility to work with dowels of large size;
• The creation of a shot of great power;
• Providing high-strength fastening of the fasteners to the base;
• Absence of additional equipment;
• Compactness and relatively small weight of the instrument itself.

Observance of the operating rules

To any of the types of construction guns is attached instruction for use. Before work it is required to study in detail and strictly observe all points. The main ones relate to the stringent requirements for ensuring tight contact between the "trunk" of the instrument and the mounting surface, as well as accurate selection of cartridges. After all, in most cases it is impossible to shoot without pressure on the fastener part, and the depth of penetration of the dowel depends directly on the strength of the powder charge of the selected cartridge.

Precautionary measures

Using a construction gun for nails, you need to use personal protective equipment:

• construction helmet;
• Safety glasses or flap;
• Special noisy headphones (group A);
• Gloves.

Preventive measures

The pistol under the construction cartridge is not a children's toy. Therefore, instructions for its operation, storage and prevention must be strictly followed. This will ensure not only safe and long work, but also will make it possible to avoid the breakdown of an expensive tool.

The main preventive measures are as follows:

• Use only branded cartridges factory-made;
• Storage of cartridges separately from the gun itself and the consumable dowels;
• Periodic inspection of the store in order to detect foreign objects that can get there when changing the clip or charging nails;
• Periodic disassembly and cleaning of the internal parts of the gun after the number of shots specified in the instruction.

Construction guns for different types of work

In addition to mounting guns designed for clogging dowels-nails, there are still various types of these tools, with which you can carry out a wide range of construction works.

These include guns, with which they apply a sealant, glue or grout joints.

The construction gun for sealant is a tool that squeezes out of the cartridges a composition designed to seal something. His 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 sheet and frame, and the latter are the most popular. They well hold the containers with sealant.

Depending on the method of extrusion of the composition, these tools can be:

• Batteries, whose worth is autonomy;
• Electric, which function from the network and are designed to work with different cartridges;
• Pneumatic.

In the latter version, the material is squeezed out by the action of air when the handle is pressed. Typically, these pistols have an ergonomic design and various devices for regulating and limiting the yield of sealant, due to which it is very convenient to work with them.

The construction gun for glue has a very simple principle of operation: a rod with adhesive composition is placed in a metal chamber where it is heated by means of a thermoelement connected to the network, and after pressing the trigger, the molten glue is squeezed out through the nozzle.

With this gun, you can glue surfaces of plastic, glass, metal, wood or leather, make docking of linoleum strips or sheets of fiberboard, repair shoes or collect broken porcelain, perform sealing, decorating or modeling something.

The construction gun for grouting joints is an indispensable tool for embroidering masonry, clinker and other types of ceramic tiles. It makes it possible to reduce material losses, keep the surface clean and accurately fill the seams without voids and air bubbles.

Using separate types of data guns, you can not only facilitate the execution of various construction and installation works, but also implement them quickly and efficiently.
