• the lighting systems 86 comprise in particular a luminaire 90 and a butt 92 carrying the luminaire 90.
• the buttock 92 is also hingedly mounted on an upright 82 of a side wall, in order to facilitate access to the luminaire 90.
• the passageway 74 also makes it possible to access pulleys 94 cooperating, for example, with tensioning cables of the sheets of tarpaulin, with the cables 32 pressing on the sheets of tarpaulin 30 to adjust the tension thereof, or with the cables 42 sections of covering tarpaulin 40.
• the ladder 96 extends from the ground to the passageway 74. It is arranged inside the building 16, the person going up or down the ladder 96 is thus protected from outside weather conditions.
• the scale 96 has a variable curvature along the beams 26.
• the different curvatures of the scale 96 are defined to reduce the size of the scale inside the building 16 and also to facilitate movement and movement of personnel inside the building 16.
• the scale thus consists of several successive parts whose curvature of each is adapted to the slope of the scale.
• the scale 96 comprises, from the ground towards the summit:
• a part 100 with a steep slope in the form of a conventional scale, which preferably comprises means for condemning its access;
• Scale 96 also includes side posts 112 and guardrails 114, to prevent the fall of the ascending or descending person from ladder 96.
• the length of the building 16 being relatively large, it will be understood that the building may have only one scale 96 as described above, which is mounted on a section 18, or several scales 96 which are distributed in the building 16, in several associated sections 18.
• each section 18 comprises a ridge 116 which is located above the upper ends of the panels 30 of tarpaulin.
• This ridge 116 makes it possible to cover the space between the ends vis-à-vis the panels 30 of tarpaulin, to complete the protection against the weather.
• the ridge 116 is also located at a distance from the tarpaulins 30, allowing natural ventilation of the building 16, thus limiting condensation.
• the building 16 comprises two end sections 18, each of which has a transverse closing wall 118, as can be seen in FIG.
• the closure wall 118 further comprises access doors 120 allowing persons to enter the building interior, as well as gates 122 allowing the passage of large vehicles.
• the gates 122 are slidably mounted transversely with respect to the closure wall 118.
• Access to the interior of the building 16 may also be allowed through side doors 124 arranged on certain sections and distributed over the entire length of the building, as can be seen for example in Figure 5.
• Transfer procedure of the building is mainly carried out according to the following steps.
• the building 16 is prepared for the separation of the sections 18.
• the covering sheet 40 covering the end beams 26 are disassembled, the electrical appliances such as the lighting 86 and the ventilation systems 88 are disconnected, the gates 84 of the corridor are closed and the ladder with crinoline 96 is doomed.
• the sections 18 are successively separated from each other.
• the locking means 60 are actuated to move the wedges 62 to their unlocking position, then the longitudinal rollers 52 and optionally the transverse rollers are coupled to propulsion units.
• Each section 18 is then moved from one location to another according to the steps described above, by selectively coupling the longitudinal rollers 52 and the transverse rollers 58 by actuating the jacks 54 with the longitudinal rails 46 and with the transverse rails 56, respectively .
• the cylinders 54 are actuated to move the longitudinal rollers 52 to their disengaged position and so that the section 18 rests on the longitudinal members 44 or the longitudinal rails 46.
• the section 18 is secured adjacent section 18 which has already been put in position by actuating the locking means 60 to move the wedge 62 to its locking position.
• the crinoline ladder 96 is put back into service, the gates 84 of the passageway are open, the cover sheet sections 40 which cover the end beams 26 are replaced, the electrical appliances such as the Lighting 86 and ventilation systems 88 are reconnected.
• no section 18 of the building is moved by its lifting by means of external handling devices.
