Description
Technical field
The present invention relates to a kind of shock insulation construction method, particularly relate to the shock insulation of a kind of air conditioner equipment machine room
Construction method.
Background technology
Although house and window sealing effectiveness in the past are bad, enter cold wind winter, summer enters hot gas, but logical
Wind effect is fine, and natural ventilation i.e. can guarantee that the quality of room air.
Along with the development of modern architecture, the raising of country's building energy-saving standard, double glazing, exterior-wall heat insulation etc.
The application of technology and product, the airtight performance in house is more and more higher, house just like become airtight jar and
Block the approach of gravity-flow ventilation.
But, according to the use situation of top-grade building, people generally feel that indoor humidity is bigger than normal, air is inadequate
Pure and fresh, therefore it is the discharge of accelerating chamber internal contamination air, most effective direct method improves room air exactly
Circulation, with accelerate indoor pollution air discharge, accelerate outdoor fresh air injection.
At present, the use of VMC achieves the most effective ventilation, by ventilation reasonable in design substantially
Path, discharges the air of foul indoor and outdoor treated fresh air is sent into indoor, can reach
Rapidly, the effect of indoor pollution air is administered economically.
But, owing to people are more and more higher to the requirement of environment of living, relative to environmental noise and vibration
More sensitive, the most anti-vibration and noise of new Ventilator Room has just become the emphasis in construction now.
The generation of existing new Ventilator Room noise and vibration is typically due to produce noise when electromechanical equipment runs,
Including air-borne sound and solid-borne noise (vibration), simultaneously because the inertia force of rotary part and bias imbalance produce
The power of disturbing part of appliance can be caused to produce forced vibration, and by plant bottom case, the connection of pipeline and building
Partial vibration produces transmission solid-borne noise with the form of sound to surrounding space radiation.
Summary of the invention
Present invention is primarily targeted at, overcome deficiency of the prior art, it is provided that a kind of air conditioner equipment
The shock insulation construction method of machine room, be particularly well-suited to higher to air quality requirements, personnel activity is more, ventilation
The more need of number of times realize the place of air exchange and circulation, such as hospital, KTV, Internet bar, hotel, business
The buildings such as field, factory, office building, restaurant, bank, classroom, kindergarten.
The technical problem to be solved be to provide compact conformation, easy accessibility, construction easily, cost
The shock insulation construction method of relatively low, safe and reliable, practical air conditioner equipment machine room, not only vibration damping fall
Make an uproar, effect substantially, and effectively solves indoor air exchange, it is achieved the most effective ventilation, reaches
Rapidly, indoor pollution air is administered economically, hence it is evident that improve living environment, environmental-friendly and comfortable, and there is industry
On value.

Glass silk flosssilk wadding is laid afterwards along carrying main joist direction；Directly snap in clad can false keel by main joist grab, cover
The spacing of face false keel is 400mm, and joint area carries out staggered, and keep staggering distance >=60mm；
Step 5-3: carry out sealing plasterboard construction, start to install plasterboard from by side, corner, plasterboard
Long side direction is parallel to carry main joist, be perpendicular to clad can false keel；The plasterboard fissure of displacement install, be formed without logical
Seam；Being fixed by plasterboard with self-tapping screw, screw afterbody gos deep into plasterboard plate face 0.5mm, screw distance plate
Limit is more than 15mm more than 10mm, distance cutting edge；Plasterboard is carried out joint treatment；
Step 5-4: carry out pasting abatvoix construction, inhales from starting to install 600mm*600mm by side, corner
Soundboard, uses building adhesive to carry out the fissure of displacement and pastes installation, and corner is strengthened fixing with nailing.
Step 6: carry out end face abatvoix construction；
Step 6-1: snap the line setting-out, is as the criterion with indoor datum line absolute altitude, finds the design of furred ceiling on metope
Relief, along metope periphery snap the line setting-out；According to snap the line, install along keelson along metope periphery；
Step 6-2: hanger erection, with 1.2m for away from snap the line on floor, beats boom hole, loads expanding screw
Bolt, fixed derrick, on the basis of keelson height, determine screw thread length of boom with horizontal line；Carry out water again
Heibei provincial opera is whole, determines top cap nut position height with horizontal line on suspension rod, and the screw screwing suspension rod reaches to want
The height asked, it is ensured that the bottom surface horizontal line of end face keel is consistent with along keelson bottom line；
Step 6-3: install end face keel and baked keel, uses suspension rod to be fixed by end face keel, reaches to want
The height asked；Use connector to be fixed on end face keel by baked keel, reach height and the entirety of requirement
Levelness；
Step 6-4: carry out end face abatvoix and lay, is placed in baking vanish dragon by end face abatvoix from left to right order
On bone.
Step 7: sound insulated fire door is installed；
Use building adhesive that door abatvoix pastes the inner side of fire resistant doorsets, and stop, use are installed on ground
In protection door abatvoix.
