The monolithic construction of multi-storey buildings: technology, requirements

Over the past few decades, monolithic construction of multi-storey buildings has become a real breakthrough for the whole construction sector. The design of such facilities contain the minimum number of supporting elements in the form of columns, bearing walls and pylons, which opens up opportunities for more rational practical application saved living space.

Reasons for the growing popularity of monolithic construction

Currently, the development of a wide range of new materials and development of innovative construction technologies greatly simplify the process of monolithic construction, making it faster and more cost effective.

Carrying out construction of monolithic houses with their own hands, the future owner understands that the premises of his imagination will be confined to the external walls of the building. It was during the construction of a private house according to monolithic technology may allocate sufficient space for the cozy and at the same time, wide enough kitchen space, creating spacious living areas, closets, interior design in the Studio.

The advantages of the implementation of projects on the monolithic housing construction know construction companies and professional realtors, as from year to year the number of people willing to live in the apartment or house of monolithic reinforced concrete only increases.

Construction of monolithic houses: technology and milestones

The construction of the home according to the technology of monolithic construction consists of the following stages of work:

• Strong Foundation;
• Mounting frame on the basis of rebar;
• Laying of concrete;
• Installation of the formwork;
• The Stripping or removal of formwork (in the case of removable stacking technology).

On construction sites for erection of monolithic buildings, the formwork is filled with concrete mixture with a high-power concrete pumps. If to speak about structural scheme of such structures, the main focus here is on a solid diaphragm and the core stiffness, which are usually formed in the field of Elevator and stair areas. These elements are responsible for the stability of the monolithic building.

The construction of the residential houses refers to the separation between flats and indoor spaces with mounting brick walls. In recent years, as an alternative to bricks for this purpose are increasingly used perlite and plasterboard partitions. This approach to space separation reduces the introduction of housing into operation since the Foundation more than 5 times. Furthermore, the division of living space in this way does not require the costs of the special forces on the trim surfaces because drywall can be applied directly to the Wallpaper or painting.

Materials

During the construction of capital construction according to monolithic technology apart from these mandatory components, such as concrete and metal rebar, most large companies emphasize the use of permanent formwork of polystyrene foam. Such elements of the design of the future monolithic building made in the form of a hollow inside of the polystyrene block, the components of which are two panels connected by bridges. Made panels and lintels of the same material or from a durable plastic. Polystyrene possesses truly negligible weight, therefore, facilitates easy, quick installation.

Construction

What is monolithic construction of high-rise buildings? The technology is simple enough, but at the same time has its own distinctive features. The main work, as in the case of any other building technology, beginning with laying the Foundation. From the quality and accurate will be the Foundation of the monolithic structure, will largely depend on the strength of the entire building.

Upon completion of all organizational activities after the required excavation is to install a specially prepared cage and cage items of the monolithic Foundation. Then when you have finished the Foundation and frame elements of the structure, including the improvement of drainage communications and waterproofing systems, the process of construction of floors with the use of reinforced concrete.

The Construction of houses made of monolithic foam concrete in the construction of columns, walls, lift shafts and pylons require the application of panel formwork, which is part of monolithic slabs. At the organization of floors, first of all, going to the formwork, which subsequently is mounted the frame of the armature.

One of the most important stages in the construction of capital monolithic construction is the development of accurate project location selection of the formwork. It addressed the issue through the use of experience qualified specialists and to attract personnel of surveying services.

The Process of concreting of monolithic structures

Concrete structures of buildings erected with the use of monolithic construction technology,made by thick uniform distribution of a pre-prepared concrete mixture in the formwork. For compaction of concrete poured into the formwork using high-powered pumps capable of serving to a considerable height, it uses special vibrating mechanisms.

The Construction of monolithic frame house in the winter season has its exceptional characteristics. To stacked concrete have gained strength and have hardened in time according to the developed project, “winter” the concrete mixture is formed with the use of antifreeze additives. While reinforcement frames the future of the monolithic structure equipped with special heating cables. The implementation of such measures during the execution of works in extreme cold greatly simplifies the construction of monolithic brick house.

Reliability

The Construction of monolithic buildings is primarily in the transfer of bearing loads on the columns are of reinforced concrete as well as reinforced floors for resistant to significant loads in-situ concrete. The application of this principle in practice is helping to build truly sustainable and extremely reliable frame high-rise buildings.

As for the barrier, monolithic buildings, they are of a purely formal nature and does not fix any of the loads. Acquiring housing in the monolithic house, you can easily unsubscribe from all partitions, having their own apartment in the spacious Studio with the most open space.

What determines the quality of construction of monolithic houses?

The Quality of performance of works on construction of monolithic structures depends primarily on the availability of flat ground structures, and also from tight control over the progress of all without exception events. The results of such monitoring must be recorded in a special log. In particular, the construction of monolithic brick house needs a thorough quality check mating cages of reinforcement, the determination of the accuracy of the positioning of the formwork, the inspection of concrete, starting from the time of his appointment and ending with the acquisition of the strength filled into the formwork of the concrete mass.

Issue Price

Currently, monolithic construction, technology of construction which have been described above, can significantly reduce the cost of finished housing. This happens due to the high speed of construction, which is caused by the possibility of using workflows with high adaptability. If you compare the price of housing in monolithic houses with the same cost in the buildings of prefabricated type, here the figure is lower by 10-15%.

The Advantages of monolithic construction

Why, today, is preferably of monolithic construction of high-rise buildings? The technology of construction of such buildings has the following advantages:

• Long service life of buildings;
• Unlimited opportunities-plan and interior of the premises;
• Higher speed of performance of construction works;
• An improved acoustic and thermal insulation characteristics due to the absence of joints, seams and voids surfaces;
• Reduced material consumption.

Disadvantages of monolithic construction

Despite the impressive number of obvious advantages, has a number of disadvantages of the monolithic construction of high-rise buildings. The technology is not without flaws, but they relate primarily to construction progress and do not belong to the quality of the finished structures. The main disadvantages of monolithic construction can be considered:

• The likelihood of serious delay for urgent implementation of the plan in adverse weather conditions that impede the filling of the formwork with concrete;
• The need for completion of all construction activities on open space, which creates certain difficulties and inconvenience to professionals of construction crews.

Conclusion

In the article we considered in detail the monolithic construction of multi-storey buildings. The technology of their construction gives an opportunity to introduce high-rise residential buildings into operation in the shortest possible time. This, in turn, is an obvious advantage not only for construction companies that need precise execution of their plan, but for future owners who purchase the housing before beginning work on the construction of an apartment building.

Using as the basis for a reliable formwork and durable metal fittings, it is much harder to prevent critical structural error or a marriage in the structure of buildings. Construction of monolithic multi-storey houses built according to latest standards, is that they have a higher seismic resistance. The wall, flooring and ceiling work as smooth surface, deprived of all kinds of seams and voids.

Only in the construction of monolithic structures residential purposes there are tremendous opportunities to implement a variety of volumetric and spatial solutions thatby itself enhances the performance characteristics of the building.

With regard to the level of environmental monolithic structures, which inherently represent only a concrete box original design, construction companies provides for setting up of brick veneer and partitions. It is the brick along with drywall and other common partitions has the highest level of environmental safety.
