Step 1, location unwrapping wire: referenced drawing is determined the coverage of plenum chamber, determines its axial location, determines the box height of plenum chamber according to designing requirement, according to the absolute altitude at the bottom of air output and wind speed requirement adjustment plenum chamber.The first floor is in order to realize plenum chamber construction and to avoid the expansion bolt in later stage to destroy pre-stress floor, at suspension-center pre-embedded on first floor prestressed hollow slab during structure construction, and the suspension centre of the first floor is carried out unwrapping wire, verifies the pre-buried quality of suspension centre, the top layer of suspension-center pre-embedded is cleared up.Two layers of steel work layer in order to make full use of the girder steel of having constructed, the installation accuracy that guarantees the horizontal main joist of plenum chamber simultaneously, increase steelframe conversion layer between girder steel, emit accurately position line.
Step 2, material is prepared: comprise the preparation of spine material and the preparation of cabinet panel material, as the scale of Sandwich glass steel composite board is made, the galvanizing processing of spine material etc., erosion for fear of the condensed water producing in plenum chamber to plenum chamber inside keel, all keel all adopt galvanizing to process, comprise flange screw, the octahedral sealing of FRIM warming plate Shi factory, glass silk flosssilk wadding is all wrapped in to the inside, the inside forms cavity, moisture cannot enter, reach good heat-insulating property, avoid on-site cutting to destroy sealing effectiveness, after materials arrival, first to carry out the specification of sheet material, intensity field test, material all should have product certificate, the intensity report of associated materials and the report of burning grade, and do in accordance with regulations the relevant checking of marching into the arena.
Step 3, welding suspension rod 8: built-in fitting 17 in the top of 50 * 3 angle steel suspension rods and floor is carried out to two-sided welding.
Step 4, weld horizontal main joist 42: at the horizontal main joist of the bottom of suspension rod 8 vertical welding, by some parallel single horizontal main joists, form main joist frame; Wherein, with the concrete operation method that channel-section steel arranges horizontal main joist 42, be:
A, be welded into a horizontal main joist by two 5# channel-section steels are back-to-back, notch is towards the right and left;
B, at the horizontal main joist of the bottom of suspension rod vertical welding, form parallel horizontal main joist support body, two-sided welding is carried out with the top of horizontal main joist channel-section steel in the bottom of suspension rod, bearing of trend at horizontal main joist, comply with stepped requirement, between adjacent two horizontal main joists, by segmented node, be welded to connect;
C, there iing on the marginal position body of wall of side wall anchoring receive limit channel-section steel 13: with expansion bolt, single channel-section steel is anchored on side wall,, height adapts with the most contiguous horizontal main joist height the notch of channel-section steel outwardly;
D, the channel-section steel 14 that binds is set on the floor of the marginal position without side wall: with expansion bolt, single channel-section steel is anchored on the soffit of top, edge, channel-section steel notch down, for intercalation side panel.
Step 5, installation bottom panel 4 and side panel 7: the edge, both sides of Sandwich glass steel composite board is embedded respectively in the notch of the horizontal main joist 42 in both sides, between adjacent two panels, adopt flange 8 to be connected to form bottom surface lath 41 in the horizontal; The bottom of side panel 7 is carried out flange with the bottom surface lath 41 of bottom panel 4 edges and is connected, and the top of side panel 7 is connected with floor 2.
Step 6, joint seal are processed: in the connecting sewing of chimeric gap, plenum chamber edge and the side wall of cabinet panel and channel-section steel or flange, filling with sealant material seals as neutral weather-resistant glue, simultaneously for guaranteeing the sealing of flange connections, in the middle of flange, establish fire seal, make plenum chamber integral sealing tight.
Step 7, weld longitudinal secondary joist 43: on the bottom surface of horizontal main joist channel-section steel, weld the longitudinal secondary joist of 30 * 3 angle steel, longitudinally secondary joist and the horizontal orthogonal formation groined type of main joist face frame.
Rustproof paint is cleared up and brushed to step 8, solder joint: all solder joints are removed to welding slag, at solder joint brushing at two sides rustproof paint; For improving plenum chamber fire endurance, to on the horizontal main joist exposing and longitudinal secondary joist, carry out brushing fireproof paint, simultaneously, for avoiding horizontal main joist channel-section steel place to occur cold bridge phenomenon generation dewfall, between the upper surface of horizontal main joist, suspension rod, cover the composite glass fiber reinforced anti-condensation cover plate of sandwich, the width of anti-condensation cover plate equates with horizontal main joist width.
Step 9, light leak test: illuminate all sites in plenum chamber at night with lamp, access door light is sheltered from, keep all light outside plenum chamber to close, check the light leak situation of plenum chamber seam, if there is light leak to overhaul in time.
Step 10, access door shutoff: after complete liquidation inside plenum chamber is clean, use the sheet material of same material, with sealing sizing material, access door is carried out to shutoff, sealant sealing is used in gap, outside again, is convenient to like this secondary maintenance and uses.
Step 11, air-supply detect: after plenum chamber and interior decoration all complete, start air-conditioning unit, for under-seat, air quantity detector detects wind speed size, so far, constructs complete.
