Architectural and construction solution.

Main purpose: production building.

- fire hazardous

- durable, fire-resistant

- by internal mode: heated

- by internal humidity mode, with normal humidity 55%

- for ventilation systems: plenum-exhaust

- for lighting systems: natural and artificial

- for internal lifting and transportation equipment: two overhead cranes with lifting capacity of 5t

- bathrooms equipped with water supply and sewerage

- internal drains

The hangar building is 121.4 m long and 60.4 meters wide. Consists of: five spans of 12 meters, 14.4 m high; span width - two by 60 m with a transverse deformation seam of 1 meter, in axes 6-7.

Reference to longitudinal layout axes is zero. The cross-axis reference is centered on the columns. End columns are displaced from laying axes inside the building by 200 mm relative to the column center.

The binding of the columns of the domestic building to the longitudinal layout axes is zero. To transverse - in the center of the columns.

Between the main building and the annex with domestic premises there is a deformation seam in the axes Zh-I with a width of 600 mm .

The total area of the hangar is divided into production areas, the explication of which is located in the drawing.

Two overhead cranes with a carrying capacity of 5 tons are provided in the spans.

Structural solution of the building.

The structural diagram of the building is frame.

Foundations for columns of railway, columnar type, two-stage. Depth of occurrence 2m. Foundations for fuselage columns - railway, columnar. Foundation beams with a length of 12 m.

The main load-bearing columns are metal, two-branch rectangular sections, height 14 .4 m, dimensions of columns in plan 1000 * 400 mm.

The scaffolding columns have a height of 12 m and the dimensions of the columns in plan 400 * 400 mm.

To ensure spatial rigidity, horizontal connections are established between the columns at a height of 6 m.

Rafter structures cover the span and directly support the flooring. The rafter truss has a height of 2.4m and a length of 60m. Substructure farm: height 2.4m and length 12m. Rafter and substructure truss series 1.460.314.

Crane beams have a T-section, and are attached to rafter trusses.

The coating consists of profiled steel flooring, steam insulation, 150mm insulation, underlying layer for membrane, and PVC membrane roof.

Internal drainage through water intake funnels.

To arrange the parapet along the perimeter of the hangar, columns are built up on the coating with fahverks and they are welded to the truss with a pitch of 12 m, wall panels are attached to the fahverks.

In a residential attached building, load-bearing columns with a height of 3 .6 m, a section of 300 * 300mm. Column grid 12 * 12m. The columns are connected by railway crossbars, along which the railway coating plates are laid. For arrangement of parapet along perimeter of coating with anchors in concrete fachworks are fixed. The roof arrangement is similar to the main body, only in place of the profiled steel sheet use a railway coating plate.

The walls of the main building and the auxiliary building are made of sandwichpanels 200 mm thick. All internal partitions are made of metal profile and giprok in two layers, and have thickness of 100mm.

All doors are blind, 2200 * 1000 mm, accepted according to the current GOST 1462484.

Tape glazing. Windows in OPS 1212V, 1210 * 1210mm, windows in OR 189A hangar, 910 * 1810mm are accepted according to the current GOST 1628986 and GOST 1121486.

In the household building there is an open gate 3000 * 2600mm.

In the hangar, the railway lifting and sectional gates 4900 * 5400mm with automatic control, series PR0556.

The main gate, rolling, consists of two parts 60.7 * 11.6 * 0, 8m each, between them a gap of 100mm. In the gate there are wickets 1000 * 2200mm. To avoid heat loss, the gate is equipped with soft insulators that fit tightly, but do not interfere with the movement of the gate. The gate has automatic control.

Floor coating and its composition: base - crushed stone layer, underlying concrete layer, waterproofing in two layers, interlayer - cement mortar of grade 300, coating from slabs of high-strength concrete 400 * 400 * 40mm.

Below, along the entire perimeter of the building there is an asphalt concrete pavement with a width of 600mm.

In the places where wall panels rest on the foundation beam, the seam with insulation is protected (galvanized cast is attached to the foundation beam by formates, the shaped element clings to the lower part of the cast and, with its upper part, by self-cuts, through 250mm, is attached to the wall panels. The use of silicone sealant is mandatory when mounting the bead.)

Fire fighting measures.

Development is carried out in accordance with the general plan.

The rooms are equipped with autonomous automatic fire detectors. Electrical equipment and lightning protection are designed in accordance with the requirements of PUE and RD 34.21.12287 .

Wooden elements of the building have fire protection (paints, impregnations, compositions, etc.).

The general plan provides for a fire station.

Engineering equipment.

The local water supply system is supplied from the central system, underground pipeline.

Pipelines, at intersections with walls and floors, are protected by corrugated plastic pipe.

Sewerage is central. Waste water coming from the premises is household and is treated biologically before discharge.

The water drain is internal.

Power supply from the external central network, from the underground cable located at a depth of 3 m. Voltage from the cable is supplied to the electrical panel. Mains voltage 380/220V.

Lighting - natural and artificial, incandescent lamps and daylight lamps.

Communication device - telephone network, security and fire alarms are carried out through the city telephone network. Alarm sensors are installed on windows and doors. Fire alarm sensors are installed in each room, the number depends on the area of ​ ​ the room.

Plenum ventilation.

Plumbing appliances: washbasins, showers, toilets, urinals installed in showers and toilet rooms.

Process description.

The repair fund, (aircraft to be repaired), are located at the parking areas of the repair fund MS. From the parking areas, the aircraft is started by the tractor into the hangar of the main building, in which disassembly and basic repair work with the aircraft, units and engines are carried out.

Repaired engines are tested in the engine test case and from there are supplied to the aircraft assembly compartment of the main body, where the aircraft is assembled.

The repaired aircraft is withdrawn by tractors from the main body and put on the MS of finished products, where ground tests of the aircraft are carried out. After that, he passes flight tests.

The tested aircraft is sent to a separate finishing and painting hull, which is located at the airfield, where the detected faults and defects during the tests are eliminated. Then it is finally completed. From the refinement hull, the aircraft comes out ready for operation.

The main body process is as follows:

Aircraft are repaired by the aggregate assembly method, in which the final assembly is carried out on assembly sections, stands, from finished and adjusted units and assemblies.

The aircraft received for repair in the disassembly compartment is disassembled into main units and units using overhead crane-beams and floor lifting and transportation equipment. Removed units and units are supplied for flushing and cleaning, after which they are disassembled for parts on special stands. After washing in washing machines, parts are delivered to the defect area. Instruments, electrical radio equipment, accumulators, after removal, go immediately to the corresponding compartments for repair.

Suitable parts are sent to the repair and assembly departments of the unit repair shop for configuration. Requiring repair - for restoration, and faulty - for disposal. Parts are restored in mechanical, thermal, galvanic, mednitskozhestyanitsky and other compartments.

In the repair shop of units from serviceable, restored and spare parts, units are assembled, tested, painted and supplied to the set section of the aircraft assembly compartment for subsequent installation on the aircraft.

Motors, electrical equipment and instruments in the respective compartments undergo the same cycle of operations, and are also then supplied to the picking area of ​ ​ the workshop.

The peculiarity of the organization of repair of engines - they are tested at a test station located in a separate building.

In this case, disassembly and assembly of the aircraft is performed on dead end post-stands, i.e. in one place without movement.
