Formwork for monolithic construction of the Gamma brand

Formwork is a building form that defines the configuration and volume of a future building structure of a rigid form, obtained by casting specialized solutions or concrete mixtures. The purpose of this concreting is to create walls, elevator shafts, columns, floors, foundations and other parts of a building of various sizes and configurations, and the purpose of the formwork in this case is to strictly adhere to the size and shape of the required construction object.

The formwork system is produced by a Russian enterprise of Moscow origin under the Gamma brand, which indicates knowledge of the peculiarities of the climatic zone where these technologies are used, which, in turn, increases the quality and durability of building structures.

Production of Gamma formwork

The quality characteristics of a monolithic structure are influenced by the properties of the materials used from which the formwork is made. Different manufacturing companies may use different raw materials. As a rule, these are the following materials:

• aluminum;
• steel;
• iron;
• duralumin;
• plastic;
• laminated plywood.

The main material from which Gamma brand products are made is high-strength steel , iron; Some assortment is made of laminated plywood. In some cases, depending on its purpose, it is presented in the form of a structure made of modular panels or panels, the material of which is selected depending on the purpose of these structures. They are manufactured on an automated German production line, and their assembly is carried out automatically by robotic manipulators by welding.

Production

The best ones that have won for their quality, characteristics and cost are construction formworks from domestic manufacturers. Many years of experience allows us to produce reliable monolithic structures for work on objects of varying heights and complexity. Gamma formwork meets all requirements and standards, therefore it is of high quality. Steel is used as the main material. It is very durable. For lightweight options, laminated plywood is used. The range of goods is quite diverse. You can choose structures for floors, columns, bridge supports, for work in elevator shafts, and structures for construction at special-purpose facilities. Offers profitable purchases of such goods in Moscow.

What is Gamma formwork used for?

The purpose of formwork systems is very diverse, both in industrial construction and in private or civil construction, hence the large range of this type of Gamma product. Let's take a closer look at the purpose of the formwork, namely, to create:

• walls;
• columns;
• foundation;
• floors;
• many other monolithic structures of various configurations.

Gamma formwork, in particular, is used for the construction of columns of round section and large oval section, as well as ribbed surfaces with a ledge, V-shaped supports, oval crossbars of bridge supports.

The presented building elements, in addition to buildings (private houses, palaces, entire complexes for various purposes), are widely used in other construction areas, namely: subways, overpasses, bridges, tunnels, various transport interchanges. The specificity of Gamma products is that they not only comply with GOST R-52085−2003, which classifies them as the first class of formwork, but also with the European DIN standard.

The list of construction projects where Gamma technologies were used is very impressive. Here are just a small part of them:

1. Sochi tunnel complex (Krasnaya Polyana).
2. Thermal power plant in Adler.
3. Moscow Oceanarium (Poklonnaya Gora).
4. Several hotel complexes in Sochi.
5. Nuclear power plant in Volgodonsk.
6. Reconstruction of the Kremlin in Moscow.

Types of Gamma formwork

By combining panels of various heights of 1.5, 3 and 3.3 m in an assembly, you can create a finished formwork of any size and height. The wall formwork structure usually consists of the following elements:

• shields (linear, hinged, internal, external);
• corner (internal, external);
• universal lock;
• arc-forming element;
• bracket;
• crane grip (quick release mechanism for lifting up to 1.25 tons);
• tie kit (for connecting panels in the designed position);
• two-level strut (for leveling the panels in a vertical position).

Detailed instructions are offered for any design , so there will not be much difficulty in understanding the component parts, since they are displayed in it not only schematically, but also in separate drawings with explanations.

Linear boards are perfectly combined with curved boards of both horizontal and vertical placement, which can be elliptical and radial . Such manipulations are necessary for the construction of structures with curved walls. The cost of radius formwork ranges from 3,000 rubles to 7,000 rubles per 1 m².

Attention should be paid to the fact that the system used for casting construction sites can be removable or non-removable . In the case where the formwork structure is permanent:

• labor costs are saved;
• it is impossible to reuse the formwork;
• additional drainage or insulating effect (when using, for example, polystyrene foam).

Gamma formwork system

The Gamma formwork system is a well-known domestic brand in the construction industry market. The main purpose is concreting monolithic walls and foundations of industrial and residential buildings, but its versatility allows it to be used for the construction of objects of any complexity. The design meets the requirements of class 1 GOST 52085-2003 and is fully compatible with the Peri Trio system from the German manufacturer, in fact, it is its analogue.

The minimum number of elements simplifies the work; assembly and dismantling do not take much time and are accessible to any non-specialist. The distinctive features of the formwork are wear resistance, reliability and durability; the closed steel profile is reinforced with stiffeners and ensures maximum geometric accuracy of the panels. Even after several years of operation, the profile and deck retain their properties; used complexes are in no way inferior in quality to new ones.

Types of systems

The range offered by the Russian manufacturer includes formwork for walls and ceilings, radial structures, elevator shaft systems, columns, bridge supports, and specialized objects. The most popular kits are for vertical monolithic sections. Depending on the project, small- or large-panel formwork is used, and the possibility of constructing curved walls from concrete is provided. The shields are made of steel or plastic, all metal elements are powder coated and phosphated to protect against corrosion.

Depending on the withstand pressure of the concrete mixture, there are varieties: Gamma and Gamma-Cascade, with the same dimensional characteristics. In the first case, the structure can withstand loads of up to 90 kN/m2, as a more rigid modification. For less critical objects, it is better to use Gamma-Cascade large-panel formwork (maximum 80 kN/m2), with a birch plywood deck.

Depending on the height of the shields, the Gamma and Gamma 300 sets are distinguished (up to 3 and 3.3 m, respectively). Any elements are compatible both with each other and with components from the German manufacturer Peri. Both modifications are highly durable and reliable, but the Gamma Cascade is considered lightweight.

Performance characteristics

Important operating parameters include:

As can be seen from the table, the Gamma Cascade is practically in no way inferior to the standard modification. When choosing formwork sizes, it is important to take into account all the design features of the systems. Thus, to assemble standard panels up to 3 m high, you will need a set of two ties and locks, and to connect panels 3.3 m high - 2 and 3, respectively. If necessary, it is possible to install additional inserts with a width of 10 cm. In this case, the Gamma locking element simultaneously fixes, aligns and tightens the panels to each other. This design feature determines the high geometric accuracy of the fixed formwork.

The benefits of use also include:

1. Durability of the frame and profile; the manufacturer guarantees the reliability of the system for 5 years of continuous operation.

2. Compatibility of elements and components, combinations of panels with a height of 1.5, 3 and 3.3 m and a width of 0.3 to 1.2 allow you to create formwork of any required size.

3. The possibility of constructing objects with a round and radial cross-section, with a ribbed or even asymmetrical surface.

4. Light weight of the formwork, which facilitates the process of assembly or dismantling.

5. Affordable prices with time-tested quality; Gamma complexes are used throughout Russia.

6. Compliance with Russian building codes (first class of formwork) and the European DIN standard.

Price

For one-time work, it is economically feasible to rent or buy used formwork. On average, renting 1 m2 of a universal set costs 280 rubles per day, taking into account the cost of components. Deck for walls - 25 rubles per 1 m2 per day, floors - from 9, but in the latter case, racks, tripods and beams are selected and paid separately.

The price of used kits is at least 30% lower, which is economically beneficial; moreover, the significant resources of the formwork allow it to be used repeatedly. It is better to conclude a lease or purchase agreement for used products with official representatives of manufacturers; specialists from these companies monitor the quality and guarantee the absence of defects.

Design features of the Gamma formwork

1. Formwork panels are a solid-rolled profile of high-strength steel , which makes them very rigid and increases the durability of the structure in the most difficult operating conditions.
2. In order to connect three-meter shields, you will need two ties and the same number of locks, and if the height of the shield is 3.3 m, then two ties and three locks. This fact cannot be ignored, as it indicates great time savings and ease of assembly.
3. The “Gamma” galvanized universal “3 in 1” lock allows, when connecting panels, to align them, pull them as close as possible to each other, and, if necessary, use an additional insert 10 cm wide, which it clamps without an outer corner. Otherwise, we can say that this lock is a leveling bolt, since its body is a plane for pressing the ribs and profile of the formwork panels.
4. The formwork is powder coated and 100% phosphated (a special solution is applied to the metal, which creates a phosphate film on the surface). This gives it not only an attractive appearance, but also corrosion resistance.

Inexpensive frame floor formwork

using floor frame formwork . This system is a frame, which in turn can be constructed from vertical and horizontal parts, which are also fixed to each other with additional elements. The connections are crossbars and diagonal braces.

Floor frame formwork kit:

• The lower jack is the supporting element of the entire system, takes on the horizontal load and distributes it evenly.
• The upper jack is responsible for adjusting the formwork system.
• The shoe is a supporting part and acts as the base of the formwork system, responsible for its installation on the floor, which must be perfectly flat.
• The starting stand is the first part and is fixed to the jack.
• The additional stand adjusts the height of the table.
• The crossbar expands the racks, increasing the strength of the structure. The wedge assembly is the connecting link between the crossbar and the rack.
• The unifork secures the wood beam and is located on the upper jack.
• The insert connects the starting posts.
• A ladder is installed to simplify the movement of workers.

User reviews

In the spring, I had the opportunity to help my neighbor assemble a “construction set.” It turned out to be a set of Gamma formwork made of steel for casting a foundation. very easy to assemble , it didn’t even require careful study of the instructions. We must not forget to check the upper edge of the installed structure for level. The geometry of the finished foundation is simply amazing!

Victor Romanov. Novosibirsk city

I already have a house on the site, and I wanted to make something like a terrace. I didn’t want to be like everyone else. I came up with this move. I bought modular formwork “Gamma”: I selected modules of different configurations (some of the panels are straight, and some are curved). I connected it with fasteners in such a way that an asymmetrical shape of the walls was obtained. It turned out original.

Pyotr Ivanovich S. Moscow

I built a house for my family very quickly (about three weeks) and relatively inexpensively, using Gamma permanent formwork. There are many advantages in addition to what I previously listed: easy to assemble, build and plaster, excellent sound insulation , minimal heat loss, and in the summer, no matter the heat, the house is comfortable.
In my opinion, there is still a minus - the need for supply and exhaust ventilation with a heat exchanger. The microclimate inside a cast house differs from a non-cast one, although, in fairness, it should be said that other household members besides me do not share my opinion. Mark Stevenson
