In an unusual way


The construction of a sports complex in Simferopol may be of considerable interest to specialists. A huge hexagonal roof weighing 1,100 tons and an area of two football fields, assembled on the ground with the help of six hydraulic installations, was lifted and installed at the design mark. The roof now rests on six 24 m high metal columns. Then 30 main columns will be installed under it. The entire lifting operation took only 15 days.


At first, it took the installers of the Azovstalkonstruktsiya trust 12 hours to raise the roof by 15 cm, and after measuring the horizontal markings, vertical columns and checking all welded joints, the speed was increased to 120-150 cm per day. It would seem that it is not much, but this speed is 10 times faster than the rate of roof construction in the traditional way. In addition, there is no need for special scaffolding and load-bearing structures. The new lifting technology has saved five months of work.

New information about the brick


The possibilities of changes in brick manufacturing technology are far from exhausted, and this is confirmed by the activities of the Tashkent Scientific Research and Design Institute of Building Materials. For example, low-temperature brick firing technology has been developed here. If a temperature of more than 1000 ° C is required for roasting raw materials, Uzbek specialists have reduced it by 250-300 ° C. This saves fuel and increases the service life of furnaces and equipment.


A lot has been done to expand the color range of the bricks. It is already possible to obtain bricks of fawn, blue, brown, and white colors. This will make a significant contribution to the decor of brick buildings, making them much more attractive.


The production of so-called effective and face bricks, characterized by increased seismic resistance, has been mastered. The former, in addition, require 20-25% less raw materials, while the latter can be used without plaster.


The institute's specialists are looking for new ways to apply glaze to raw brick beams.

Lazdinaya's Pride — monoliths


Vilnius is home to hundreds of unique historical and architectural monuments in the city center and modern structures that successfully compete with classical era ensembles. For example, the residential neighborhood of Lazdinai has become a modern landmark. 17-storey towers, built in a monolithic way, have become the high-rise dominants here. Vilnius builders have seen the advantages of the new method in practice. Compared to panel houses, monoliths require half as much money for the organization of a construction production base. The expanded clay wall material used to fill the formwork forms is made directly on the construction site, which significantly speeds up the process of building construction, eliminates the need to deliver ready-made building structures to the construction site and makes it possible to create new forms.


Residents of monolithic towers are satisfied: the external attractiveness of the buildings is combined with good heat and sound insulation.
