The basis for determining a constructive solution of large-panel residential building is its structural diagram.
In practice, the design and construction of large-panel buildings used a significant amount of different design schemes, because of the large variety of space-planning decisions, different levels of development of building materials industry and production of precast products, security of construction sites lifting and transport equipment. The importance in the choice of structural schemes is their techno-economic evaluation. Depending on the constructive scheme of the building materials are defined and the nomenclature of assemblies, depend on it the methods of construction of buildings and technical-economic indicators of large-panel construction.
On the constructive scheme of the large buildings, divided into the frame, and frameless buildings with an incomplete skeleton.
Prefab large-panel houses main structure has a frame consisting of columns and beams. The columns of frame are available both at external, n internal walls; girders can be placed transversely or along the building. Continue reading
Underground tunnels which are found on all continents of the Earth. Riddle of man-made structures is still not solved by experts. For what purpose and who built their team are not known. [more]
Ancient tunnels under the ground
Jan Piek Polish researcher believes that the ancient tunnels are located all over the planet, including the oceans. These tunnels as if burned into the earth. The walls of the tunnels was hardened melt rocks, very similar to glass. Modern professionals are still unknown such tunneling technology. The age of the oldest tunnels about a million years, they were found in 1965, Juan Moritz ethnologist from Argentina. His expedition explored the province of Morona-Santiago in Ecuador, and struck a map of the tunnels located at a depth of 230 meters. The walls of these tunnels are very smooth, as if polished, the walls have ventilation pipe. The length of these tunnels hundreds of kilometers in different directions, one direction leads to the Pacific ocean. Still most of the tunnels are unexplored. Continue reading
