Innovate Solution in Construction

One of the new and promising directions of GC "Elticon" is the development of high-tech factories of industrial housing, prefabrication structural systems efficiency (frame and wall), providing a flexible layout of the premises using modern ways of joining the building structures and technological added value for their production.

This approach improves the efficiency of the construction of mass housing through the introduction of technology assembly building at the construction site of the factory-made products without the use of welding processes, which reduces postroechnyh labor, time and cost of construction.

Factory production quality production of structural elements, control and periodic tests, confirming the parameters of prefabricated structures, can significantly reduce the safety factors in the design without compromising the reliability of buildings. The use of well-designed, optimized and validated tests of serial structural elements provides the necessary strength, thermal and other properties of the elements of the building at a minimum flow of materials. With the development of technology prefab building is constantly being developed and improved connection technology are changing the design of nodes and elements of the interface. Gone also are the ugly, constantly running and freezing through the joints of panels. Stitches modern prefabricated buildings are not striking, and effective insulation and waterproofing materials provide warmth and moisture protection uniformity exterior walls.

Development of methods of analysis and design of precast concrete structures possible to replace the usual Svjaseva member connected to the structure by means of welding and mortgages, special unifying reinforced seams and joints of precast elements. The elements themselves are now interconnected by screw, loop, and other types of anchor bezsvarnyh compounds. New methods of connecting structures can not only provide the reliability, consistency and stability of the building elements, but also effectively withstand various adverse effects, including progressive collapse and seismic activity. In the building design can be used various ways to connect prefabricated considering features and experience of construction companies in the region, as well as the wishes of the customer.

Building wall structure

For the construction of residential buildings of the simplest and most rational can be recognized by wall construction scheme with walls of reinforced concrete panels and slabs of hollow core slabs forming formless. The vertical walls are load-bearing structures of the building, the horizontal overlap. The strength and stability of the building is provided with teamwork horizontal overlaps and vertical disk walls, combined with modern special reinforcement and connection technologies into a single spatial system. Step-load-bearing walls can be up to 7.2 m in height of the section of floor slabs of 220 mm. This allows the design of non-load bearing walls inside the apartment, which provides flexibility intra layouts, the ability to change them at the request of the residents. Depending on the number of storeys of these buildings can be designed with journalled plates on the transverse or longitudinal wall. Bearing plates on exterior walls, can usually be done in buildings up to 10 floors and a height of at least 3m floor. This scheme is used when the device built premises on the ground floors of buildings, ensuring free volumes within a half-width of the building. When a beam is supported by transverse wall panels are erected buildings up to 25 floors. Retail premises with increased height performed on the first floor, with built-in flexibility of planning premises is limited to increments of transverse load-bearing walls. Buildings data types have the lowest cost, easy to assemble, may be implemented as sectioned and spot type. Plastic facades can be achieved using the speakers, and the volume of sinks, bay windows differently th form. The houses can be designed different types of ladders, balconies or hanging balconies.

Building frame structure

Residential building frame structure can solve almost any problem obemnoplanirovochnye as technically ensure their implementation. This structural system provides free space on all floors of the building, the different height of floors in the same building for the housing of any level of comfort, allows to build facilities for various purposes, as in the above-ground and the underground part of the building. Structural elements: columns, girders, diaphragms, as well as formless plate molding manufactured at the plant, provide an opportunity to build the most sought after and expensive today frame buildings on the same dates and for the same cost as the cost prefabricated homes. It is in the prefabrication frame houses reaches a minimum value of specific indicators of consumption of concrete and reinforcement per square meter. The vertical load-bearing structures of frame buildings are columns, horizontal - girders and slabs. The strength and stability of the building is provided with teamwork columns, horizontal overlaps and vertical drive diaphragm stiffness. Modern frame buildings have Svjaseva plates are mounted on the threads to melt journalled formless plates spinning on the crossbars. The special design allows the columns to the bearing beams of any of the four sides of the column, and, if necessary, at arbitrary angles. The use of precast concrete frames allows you to design a building height of 25 floors and more. Bearing capacity in high-rise buildings is achieved by using a larger cross section of reinforced concrete columns or steel-concrete columns.

In frame buildings girders are usually located along the exterior walls and in the central part of the building where, as a rule, are located hallways and utility rooms. In the case of structural beams need to drive in the living room, instead of reinforced concrete beams, using special hidden prefabricated reinforced concrete girders. Panel for the exterior walls do not have support and are set to overlap. Plastic facades, as well as in the homes of the wall structure can be secured using the speakers, and the volume of sinks, bay windows of different shapes. With a small number of floors in homes can be designed different types of ladders, balconies, high-rise buildings in the hanging balconies, spaced randomly on any parts of the facade. Frame house, as the house wall structure can be designed one, two or multi section.
