the example of the completed project reconstruction of a historical building in Odessa, member of the Board of Directors of the Confederation of builders of Ukraine (CCU) - company TPK - demonstrates the benefits of using steel structures.
the Main cause of reconstruction overlap the critical combination of defects, damage and fatigue manifestations of the structural elements supporting or enclosing part of the ceiling, form the unsatisfactory level of the technical condition.
Among the factors that complicate the work often are: the uncertainty of the actual values of indicators of carrying capacity, the limited conditions of construction works (and associated technological limitations), cultural-historical and town planning restrictions.
this complex subject from the point of view of the current technical condition and evaluation of possibilities of reconstruction was building in Odessa on Pushkinskaya street, 12.
Technical condition of the house before the reconstruction:
- poor appearance (facades);
- unsatisfactory technical condition of the internal walls;
- unsatisfactory technical condition of the overlapping;
- poor condition of roof system;
- unsatisfactory technical condition of the roof;
the unsatisfactory condition of engineering networks;
- discrepancy to requirements of fire safety;
- low level of comfort and support processes of life.
Architectural and design solutions to improve the functional quality and the technical condition provide for the creation of a new structural system of the building interior.
the basis of the constructive solution is the construction of new, steel-concrete composite slabs using profiled decking sheets of TP-85 ACCORDING to TU U V. 2.6-28.7-30703438-001 in 2010.
Constructive solution to cease with the use of TP-85ПО
steel-concrete Composite slab is a composite structural elements for construction of objects composed of steel elements and concrete. In the composition of the composite structures overlap the perception of the compressive stress provided by concrete (concrete) and tensile stresses - the steel elements (letters or profiles) that perform the functions of the working reinforcement.
Application sheets profiled sheeting TP-85 allows it to be used as permanent formwork during the construction of slab as main reinforcement for the perception of combinations of loads for the operational phase of the composite steel-concrete floors.
the Rejection of the use of additional working reinforcement (reinforcing core elements) of the cross section of the slab and, accordingly, minimization of welding significantly reduced the consumption of building structures, duration and complexity of the construction process.
Technical condition of the house after reconstruction
Almost all of these shortcomings the technical condition is resolved through the implementation of innovative solutions.
Positive experience with sheets profiled sheeting TP-85, showed the fundamental possibility of the reconstruction of floor slabs. Device for the reinforced concrete slab can be viewed as a modern technological solution to the challenges of reconstruction and new construction.
