Arched design with all other conditions being equal, will always be stronger, safer and cheaper structures of other types — especially when the arc itself consists of rods, working only on tension and compression. At the time, it was appreciated by the famous mechanic Kulibin, who created a scale model of the arch bridge, which was supposed to connect the banks of the Neva. The original arch design, suitable for the creation of greenhouses, conservatories, sheds, garages and other structures, have managed to create a reader of our magazine from Novgorod S. Y. Makurin. The module of such a set represents a Central design consisting of 240 wooden rods (rails) with cross-section 20×50 mm and a length of from 0.5 to 1 meter (volume of the material is 0.2 cubic meters). The module area is 15 square meters. Docking these modules, you can get the arch structures of any size and different configuration.
