Prefabricated monolithic structural systems are known in the Indian market. However, similar technologies currently existing in India do not allow the construction of high-rise houses due to the fact that a hinged connection is formed between the floor slabs and columns ( rectangular section columns and hollow floor slabs). While “KUB-2.5” is designed for such a height - up to 25 floors - (square section of columns and solid floor slabs) due to the rigid connection of the slab and column.

All reinforced concrete products are produced within the construction site with the organization concrete plant within walking distance. The GarantStroy company sends its specialists to assist in the organization, control and training of Indian specialists in the production of concrete products, since the KUB-2.5 technology is new for the Indian user.

Using the crossbar-less frame of the KUB-2.5 system

during the construction of residential and public buildings.

1. System capabilities:

This technology can be used in construction

- residential buildings;

- public buildings (schools, kindergartens and hospitals);

- administrative buildings;

- trade and warehouse complexes, as well as for complex development of military

and construction camps.

2. Advantages of the system.

As of today Russian market The structural system of the crossbarless frame "KUB-2.5" is the only one in which the crossbarless frame is fully prefabricated.

The frame of the building in the system of structural frameless frame is a spatial structure, such as a “shelf” of prefabricated monolithic design. Columns serve as frame supports, floor slabs serve as crossbars, and braces or diaphragms are used for stiffening elements. Stairs, ventilation units, and elevator shafts can be used in any manner mastered by manufacturing plants. Load capacity ceilings allows the use of the frame in buildings with load intensity up to 2000 kg/m2

The KUB-2.5 structural system is based on an original interface between two main elements - a panel and a column using an embedded part - a steel shell special design connected to reinforcement cages located in the body of the panel. The concrete in this unit operates under conditions of all-round compression, as a result of which it self-strengthens. This made it possible to avoid welding at the joint of the columns; only assembly seams are present in the assembly. Welding work required when installing an above-column panel, in a column-panel assembly, when welding four connecting parts that transfer installation forces from the panel to the frame reinforced concrete column. The connection of reinforcing bars between the frames of the upper and lower columns of the KUB-2.5 system is required only if there are tensile forces in the sections of the columns, or in the most loaded columns. In the vast majority of cases, this connection can be omitted.

The joints of the elements that make up the transomless frame as a whole are monolithic, forming a frame structural system, the crossbars of which are the floors.

3. Speed ​​and ease of installation

When developing the frame of the KUB system, solutions were used that significantly shortened the construction process of constructing the building frame:

• installation of vertical structures is carried out on several floors at once;
• the design of the column joint does not require welding of the load-bearing reinforcement;
• there is no need to install (and then repeatedly reinstall) formwork;
• the designs of the joints of columns and floor panels between each other do not require the installation of special formwork to embed the joint, which reduces construction labor intensity;
• ease of installation is also achieved due to self-fixing of elements and factory standards;
• KUB-2.5 slab products are stored in stacks of up to 10 pieces, which allows you to successfully work in a cramped construction site.

In addition, the installation of the frame can be carried out in any weather, and a small number of workers on the construction site reduces the likelihood of using unskilled labor

4. Required level of specialist training

Due to its simplicity, the KUB-2.5 crossbar-less frame system does not require special training from installers. The level of training of reinforcement workers and concrete workers at factories of reinforced concrete structures should not be higher than for the manufacture of the range of products that this plant has mastered.

5. The degree of factory readiness of frame elements and their quality

The factory technology used in the system for the production of building elements allows the maximum transfer of labor costs of builders to workshop conditions, thereby significantly reducing the risks of both natural and human factors on the construction site.

All elements are completely ready for installation after gaining the required strength in the factory. The quality of products of the KUB 2.5 system is controlled at all stages and undergoes double quality control:

1) at the factory of reinforced concrete structures

2) at the construction site, during acceptance and installation of the frame.

6. Reliability of the frame

The universal transomless frame (“CUB”) has been built for several decades.The strength of the KUB-2.5 frame structures is confirmed by technical calculations and numerous tests:

• KUB designs were reviewed by the Scientific and Technical Council of the State Committee for Architecture under the USSR State Construction Committee and recommended for use by letter No. IP-7-3691 dated September 19, 1986;
• TsNIISK them. Kucherenko of the USSR State Construction Committee, the KUB frame is recommended for use (conclusion dated March 15, 1990);
• Dynamic testing laboratory of TsNIIEP housing under the direction of G.N. Ashkinadze.

IN recent years More than a thousand objects have been built in Russia and abroad using the KUB-2.5 transomless frame.

7. Diversity and freedom of architectural solutions

Despite the modularity of the KUB-2.5 system panels, interfloor ceilings can take on a variety of shapes and heights, thereby allowing you to solve any architectural problems in the design of residential, public or industrial buildings. Support frame the building consists only of internal elements (columns, floors and, if necessary, connections or diaphragms). Almost any façade solutions can be used as external enclosing structures (walls): lightweight, thermally efficient, stone (including brick-lined), various curtain panels, ventilated facades and stained glass fences. All reinforced concrete structures KUB 2.5 systems allow you to design buildings of the 1st degree of fire resistance.

8. Amount of cast-in-place concrete during installation

Monolithic concrete required only for sealing seams between slabs and at the column-panel joint. Since there are no additional structural elements Apart from the KUB-2.5 elements, installation is not required, the amount of concrete is minimal.

9. Minimum weight of the frame of the KUB-2.5 system

External walls are not load-bearing, there is no need to build foundations under them, and they do not need to be designed as strong as is done in frameless buildings. The load on the base of the frame is 25% lower than in a monolithic version. Regardless of the ground conditions, the volume of foundations required to distribute forces to the foundation from the above-ground part of buildings made in the structures of the “KUB-2.5” system will always be minimal, because The dead weight of the frame is also minimal due to achieved optimization all sections. This is especially important in poor soils.

10. Number of required installers

A team of installers of 5 people and one tower crane operator can install 300 sq.m. per shift (8 hours). frame "KUB-2.5"

11. Economic justification

Reinforced concrete structures of the KUB-2.5 system are not only rational, but also optimal due to the solutions embedded in them. Rationality is expressed in reasonably substantiated, thoughtful constructive solutions, providing minimum quantity building materials(steel and concrete) and labor costs.

12. Saving materials:

• consumption of reinforced concrete in the frame (floor panels, columns, grouting joints) is: 0.179 m³ per 1 m² of floor area;
• steel consumption in reinforced concrete frame elements, incl. reinforcement and rolled, is: 14.3 kg per 1 m² of floor area.

Labor savings:

• construction labor costs - 0.51 people. hour per 1 m² of floor area;
• factory labor costs – 1.92 people. hour per 1 m² of floor area.

13. Construction of facilities in seismic areas.

Transomless frame structures are intended for use in different regions Russia, including in areas with seismicity of 7-9 points.

14. Conclusions:

The universal crossbar-less frame “CUBE -2.5” is:

- economic efficiency due to low labor costs for installation and high speed of frame construction,

- saving on energy resources and the use of fixed assets, due to the speed of frame construction and reducing the operating time of tower cranes,

- low consumption of reinforced concrete per 1 sq.m. frame floors,

- savings on arrangement of foundations for buildings and structures.

15. This technology is currently being used in India on the construction of a 15-storey residential complex with an area of ​​90,000 m2 "Summer Palms", located in Bahadurgarh, pcs. Haryana, Ahluwalia Contracts India Limited (ASIL); customer – Umang Rialtek (Umang).

DESCRIPTION OF THE INFORMATION SYSTEM NPO "KUB"

KUB-2.5 structures are designed for the construction of buildings up to 25 floors and higher in climatic regions I-IV both under normal conditions and under conditions of increased seismic activity up to 8 points. It is also possible to construct buildings up to 16 floors high and in areas with seismicity up to 9 points.
The frame is easy to manufacture and install. Simple frame products geometric shape and have a limited number of standard sizes, which greatly facilitates its development. The stock of forms is minimal; the forms themselves are simple and technologically advanced.
Elements of a transomless frame can be easily manufactured in newly developed areas, in the absence of an industrial base, as well as in places where the production of frames of existing series has not yet been established. A transomless frame has architectural, planning and structural advantages over traditional block frames.
In some cases, a smooth ceiling allows you to avoid expensive suspended ceilings necessary for hygienic, aesthetic or technical requirements.
The reduced construction dimensions of the floor make it possible to reduce the cubic capacity of the building by 5-8%. The presence of a cantilever part along the perimeter of the ceiling makes it possible to conveniently solve temperature-sedimentation joints, adjoining to other buildings, installing galleries and sun protection elements for the southern regions.

One of the advantages of the frame is the reduced consumption of steel and cement per 1 sq.m of flooring compared to frame systems used both domestically and abroad.
Another advantage is ease of installation.
The form-building capabilities of the frame have a wide range from single-story to multi-storey buildings with a complex architectural and spatial solution.
Experimental and theoretical studies conducted at the TsNIIEP Institute of Housing confirmed the rigidity and strength qualities of the structure, as well as the reliability of the calculation premises.

The frame without crossbars consists of columns square section and flat floor panels. The floor panels have plan dimensions of 2.98 x 2.98 m, so the gap between them is only 20 mm and this makes it possible to embed the seams without installing formwork. Panel thickness 160 mm. The system provides two-module panels obtained by combining two adjacent panels: 1. Supracolumnar and intercolumnar. 2. Intercolumnar and middle.

This allows you to speed up installation by half and save on sealing joints. Floor panels, depending on their location in plan, are divided into above-column, inter-column and insert panels. The division of the floor is designed in such a way that the joints of the panels are located in zones where the magnitude of the bending moments is zero. The spatial rigidity of the structure is ensured by the monolithic connection of elements (floors and columns) and, if necessary, by the inclusion of connections and diaphragms in the system.

After installing the reinforcement in the seams between the panels, the seams are grouted, and at the same time the joints of the above-column slabs with the columns are grouted throughout the entire floor at this level. The seams between the slabs are used to pass utility lines. Frame structures are designed for the construction of buildings using a frame or frame-braced design. The number of storeys according to the frame scheme is limited to 5 floors; according to the frame-braced scheme it is practically unlimited, provided that the strength properties of the columns are ensured by increasing the percentage of reinforcement for the introduction of rigid reinforcement. The joints of the frame elements are monolid, forming a frame structural system, the crossbars of which are the floors. Installation of multi-storey frame frames is carried out using simple devices. Mobile or tower cranes with a lifting capacity of 5 tons and above are used as lifting equipment. Installation of structures is carried out in next order: columns are mounted and embedded in foundation glasses, above-column panels are installed and welded to the column reinforcement, then inter-column panels and insert panels are mounted.
