When the bench method can use the steel or reinforced concrete forms the matrix, which is usually cheaper. Advantage of the concrete matrix is the ease with which its surface can be given a curved shape. Wood and wood-forms are used less frequently, with small production volumes. The disadvantage of the wooden forms is their low strength and large deformability, especially under the influence of steaming, resulting in items manufactured in the same form can differ from each other. Reinforcing products should be designed so that they can be manufactured in the form of plane frames and grids, welded to the multipoint automatic machines. Since multi-point welding machines weld mesh width of 3 m, it is advisable to several identical frames merge into one wide net, and then cut them.

Nets and cages should be designed so that the step and the diameter of the rods are constant multiples of the module and 100 mm with a variable step is necessary readjustment of the machine. If necessary, change the pitch or diameter of the rods in those areas that require additional reinforcement, it is recommended near the main attach additional frames or grids. Should use the ghosts-metal welded wire mesh. Shaping of curved elements to provide the necessary protective layer during the installation frames and use plastic nets or other fasteners. Sometimes it catches hold in the form of rebar hooks, pre- welded to the frame. Curved molding products can be done the same or similar mechanisms as molding plane products: can be applied screeds, sliding vibroshtampy, vibroprofilery, large vibroshtampy, vibrating tables.

I'm studying at the Faculty of ASOIiU. That is, without zaumstvovany for a software engineer. Computers began to get involved somewhere in the class of 7. I do not remember exactly. As he entered the Institute, the attraction has fallen, but no interest. In fact, raised this question because he remembered: at the end of the tenth grade in our school held a sort of elective courses in psychology.

As far as I remember there went 3 boys and 4 girls. Statistics big role essentially no role. So, on one of the such courses, it was necessary to write, who do you see yourself in the past, present and future. More precisely it was necessary to draw it. So, remember what I drew three computers. Small, mediocre and great. Explained easily – Word, user, the expert. Of course, the goals I had and still are a few others.

And the dream is weakly related to computers. It's not even that. The fact that at that moment, all three guys have painted the past, present and future (in one way or less) associated with the profession. All understandable, of course. All the guys think about the family, but especially important to them: the ability to provide for his family, do not let her in need of something. That is why both past and present, and future – one or other profession (except the last one guy). All of this was the background. Now we turn directly to that, what raised the issue.
