Reinforced concrete slabs are used today in construction everywhere. Their strength is due to the presence of a frame, for the manufacture of which a special fixture is used.
Purpose of the lock
This is a consumable, which is aA special stand used to create concrete structures. Made of high-strength plastic, it acts as a protective barrier when it is required to prevent the output of reinforcing bars on the surface. This can disrupt the integrity of the surface and increase the risk of corrosion from external factors. Therefore, under adverse environmental conditions, the protective layer should be thicker, more durable and uniform throughout the product's surface. When manufacturing a concrete screed it is very important that the metal grid is located strictly in the center of the plate.
To provide these conditions and to hold the frame, carrying out the role of the spacer, the fixators for the reinforcement help. They can have a different design, and accordingly, and scope.
Types of clamps
In general, they are divided into vertical andhorizontal. The first are a small plastic tube or a tripod with holes in the upper part, intended for fixing the bars of the armature. Place each lock under the reinforcement bar approximately one meter apart.
Horizontal fixation in the form of profile ringsUsed in the creation of vertical concrete structures. The concrete layer should not cover the metal grill by less than 4 cm. The reinforcement bar prevents the clamping of the frame to the formwork, which ensures high quality of the reinforced concrete structure.
Advantages of fixatives
This material is considered expendable and remainsinside a concrete product that will serve for more than a decade, so one of the advantages of fixators is their resistance to temperature changes. They are not afraid of environmental influences, various chemicals, do not lend themselves to deformation, which allows them to be used in any conditions. Among other advantages, the environmental friendliness of the material from which the fixatives are made is of no small importance.
The retainer of the protective layer of the reinforcement providesthe creation of a solid and safe construction, significantly accelerating the construction process. With its help, you can easily fix the rods in the right position, without compromising on quality. This is a universal product, suitable for various fittings, available in the construction market.
Clamp "high chair"
It is considered the most popular of all types of fixatives, being a fairly reliable component material. It is used mainly for horizontal reinforcement.
The special structure of the fixer "stool" allows notonly to connect a large amount of reinforcement, but also to ensure the high strength of the structure being created. In this case, the use of this printer gives an additional economy of finance.
Fixing armature "star"
It is no less in demand in the construction marketa retainer of a different kind - an "asterisk", so named for its shape resembling this figure. Apply it in those cases where it is necessary to fix the reinforcement in a vertical surface. Such a clamp makes it possible to create a protective layer 10-50 mm thick (in large hydraulic structures it can be up to 120 mm). The construction market offers today a large selection of these materials, different in size and price.
Triangle lock
Features of the design of the fixator of this kindallow it to be used to strengthen the formwork systems and to create a protective barrier in the horizontal planes. Due to its characteristics, the location of the holes and their size, it is suitable for creating protection from materials with different diameters, which makes it universal.
The fixture of the "triangle" armature also hasa number of other advantages that guarantee the strength and safety of any connection. This type of components can be used to create any protective layers in a concrete structure. These fixatives are made of the same materials as other types, so they are not inferior to them in strength and resistance to aggressive environmental influences. More often than not, they find application in factories that produce various reinforced concrete products, but they can also be used in other jobs.
Fixing technology
Qualitatively executed works on creation of anyreinforced concrete products guarantee their durability and safety. Correctly installed reinforcement fixator plays in this business not the last role. First of all, it is required to carry out a careful marking of the place where the reinforcing mesh will be located and the placement of the clamps determining the thickness of the protective layer. Depending on it, calculate a step that can be from 80 to 100 centimeters.
When double reinforcement is required, the locks are set perpendicular to the plane of the mesh or frame. The step is aged in this case a little more - from 1.5 to 2 meters.
