Columns At Garage Building
posted in Car Insurance Savings |Columns at garage building more often have square cross-section cutset. However on planning decision there can be expedient an application of columns of rectangular section; at placing of columns between places of parking the width of section of a column, as a rule, remains to a constant on all floors. The round columns, which are receiving a positive estimation of drivers and not demanding substantial growth of expenses, are used successfully.
For the device of overlapping almost all systems applied in usual many-storied building, for example the plates reinforced in one direction or in crisscross manner, braced and ridge plates, flat overlapping with usual reinforcing are suitable. Only in exceptional cases at the big bays and small building height there can be expedient or necessary a preliminary pressure of beams.
In standard cases braced plates give quite economic decision and only at very small building height of designs it is necessary to prefer mushroom-shaped or flat overlapping. Comparative calculations repeatedly showed that the economy on a timbering of the flat overlapping, reached at application of modular designs, is blocked by expenses of concrete and a steel because of bigger thickness of modular elements for static reasons and the additional weight connected with it.
Necessity of application of special measures for processing of a surface of overlapping, for example, a vacuum method or the chemical means getting and hardening in the top concrete layer that raises its durability, blinding with hardening additives or drawings of a bitumen layer in many respects depends on loading on overlapping and interests of owners and users of garage,
which are compelled to reckon with increase in service life of overlapping at decrease in allocation of a dust.
Usually from influence of gasoline, oils and salts it is enough to apply concrete steady against unfreezing salts to protection of overlapping, to increase the thickness of overlapping found by static calculation, wearproof layer in the thickness 1 — 2 cm and to scour a surface without maintenance of its horizontal position.
On stages and strongly loaded overlapping in wearproof layer in the thickness of 2-5 cm are brought additives for increase of durability of a cloth. Besides, it is recommended to profile a surface of a cloth of stages furrows depth to 2 cm.
Staircases erect simultaneously with floors. In buildings in height not less than 15 m expediently application of a sliding timbering, and at height more than 20 m such way of building should be preferred for economic reasons.
Basically, all monolithic designs of a building can be carried out in a usual wooden timbering, however in certain cases for aesthetic reasons it is necessary to create a smooth concrete surface on a facade or to apply to elements of a parapet concrete with the bared stone skeleton or a structural timbering.
