The technology of monolithic construction of buildings is a promising direction in construction. It has undoubted advantages. The main ones are:

• the speed of the construction of objects;
• a variety of architectural solutions;
• comparatively low cost.

Types of formwork

Proper formwork creation is an integral part of the qualitative implementation of monolithic construction. There are two main types of formwork for monolithic construction:

• removable;
• non-removable.

The construction of houses from non-removable formwork does not provide for its additional processing. The formwork is based on polystyrene foaming. This makes it possible to create structures of various configurations: longitudinal, angular, superframe, submap, etc. The non-removable formwork is the main element in the monolithic erection of cottages and houses in the private sector. The application of this technology allows you to implement two operations at once:

• build walls;
• war down a house.

The main area of \u200b\u200bremovable formwork is the construction of multi-storey buildings. Its manufacturer is made of wood, plastic, aluminum and steel. It is processed by a special solution before use. It makes it easy to remove the formwork upon completion of work. For removable formwork, characteristic are:

• versatility and practicality (used up to 300 times for the construction of various types of objects);
• reliability (withstand large loads);
• efficiency (cost savings due to the multiple use).

The effectiveness of the use of sliding formwork

One of the designs is removable sliding formwork. It has to be mobile, constantly moving up in the construction of high-rise buildings. The method of sliding formwork will significantly reduce the time and cost of the construction work. Especially the use will be effective in the construction of the sliding formwork when:

• erected several buildings near;
• it occurs construction of single buildings exceeding 25 m in height;
• it carried out the construction of "skyscrapers" having the minimum number of embedded elements and parts, door and window openings.

The main difference between the sliding shuttering technology of reinforced concrete structures is the lack of joints. Due to this improved many operational characteristics of the building, including soundproofing and insulation.

Who will not be difficult to make the sliding formwork by hand. Its constituent elements are:

• two rows of panels, which are identical in size;
• beams, which are arranged at the inner and outer side shields;
• jacking frame located around the perimeter of the casing in the upper part;
• jacking rods (or tubes), a length of 6 m and a diameter of 25-28 mm.

Brick in the photo and the reality of large-panel and can be small-panel. Despite the complexity of installation work, the most universal is a small-panel design. Shields may be formed of any configuration (curved, flat, etc.), which makes it possible to erect buildings with different architectural forms.

In most cases, as the materials used to fabricate the formwork, act metal and wood. Beams and floorings made of wood, and the other elements - of metal. For example, the best decision at the casing inner surface of the formwork boards will use the steel sheet.

There are some basic work with the use of sliding formwork:

• strengthening door and window openings;
• reinforcement structure;
• capacity jacking rods;
• mounting base constructions;
• pouring concrete mortar.

Nuances of creating formwork and of work

The principle of device and formwork is as follows. The beams are powered by the jar of metal. In turn, the frame affects the rods that the bearing capacity of which should exceed all existing loads. The attachment of the jack rods is carried out to the reinforcement, which is located at the top of the foundation of the building. For this use electric welding. Gradually occurs the extension of rods in height, and the joint is on the thread.

On the frames install jacks (electrical or hydraulic), with the help of which the formwork is lifted by rods. Load capacity of jacks is 6-10 tons, weight 16-21 kg. The horizontal sliding formwork flooring is carried out on the upper beam row and frames. This design is designed to locate workers and tools.

In this case, there are also the requirements that should be observed in the device of monolithic construction. These include:

• preparation of high quality concrete solution;
• continuity of mounting of reinforcement and pouring concrete mix;
• strictly vertical formwork movement;
• timely delivery of the solution;
• the wall thickness of concrete structures should be 12-25 cm.

The initial stage of concreting in the sliding formwork involves laying a solution with a height of 70-80 cm throughout the perimeter of the structure. After that, a 30-centimeter layer of concrete is gradually added. At the same time, we seal the entire mass with the help of a building vibrator. It is recommended to pour a concrete solution to produce immediately throughout the perimeter of the structure. The laying of each subsequent layer occurs before setting the previous one.
