Description
Technical field
The present invention relates to the metal roof structure.
Background technology
For super large space building, there is following several of main problems:
1, roof waterproof grade height in case seepage takes place, can cause huge political fallout and economic loss;
2, can produce impact sound to roof panel because rainwater drops on the roof panel, because wind action also may be created in the wind song on the roof, perhaps other outdoor noises all finally can pass to indoor by garret simultaneously;
3, in addition, as everyone knows, glass wool or rock wool are light because of its quality, performance is good, as the roofing/metope heat insulating material of modern architecture extensive use, if bad but the protection against the tide of containment system is handled, then indoor water vapour is easy to permeate in containment system for it, make heat-preservation cotton mouldy, rotten, thereby reduce heat-insulating property greatly.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of metal roof structure, improves the waterproof effect of metal Roof, and it is indoor to avoid outdoor noise to pass to simultaneously, also will improve the saturating vapour effect of heat-holding dampproof of metal Roof in addition.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of metal roof structure, the roof construction orlop is the interior lining panel of steel, the roof construction the superiors are the Al-Mg-Mn alloy roof panel, it is characterized in that: between Al-Mg-Mn alloy roof panel and interior lining panel, also be provided with supporting steel plate and plasterboard, wherein supporting steel plate is supported on the plasterboard bottom, be filled with superfine glass silk flosssilk wadding anti-noise layer between described Al-Mg-Mn alloy roof panel and the plasterboard, described supporting steel plate bottom is provided with the support purlin and supports, be equipped with the nonwoven dust layer on the described interior lining panel, described nonwoven dust layer is provided with the glass wool sound absorbing layer, be filled with heat-preservation cotton between described glass wool sound absorbing layer and the support purlin, between heat-preservation cotton and glass wool sound absorbing layer, be provided with every the vapour layer, between superfine glass silk flosssilk wadding anti-noise layer and plasterboard, be provided with the water-proof air-permeable layer.
Preferably, the thickness of described Al-Mg-Mn alloy roof panel is 0.9mm, and the thickness of described plasterboard is 12mm, and the thickness of described supporting steel plate is 0.4mm, and the thickness of described interior lining panel is 0.5mm.
Preferably, described support purlin is several shaped steel of cold bending thin wall.
Preferably, described every the vapour layer for the spy of Du Pont defends strong SD2 water-proof air-permeable film, described water-proof air-permeable layer is strong water-proof air-permeable film for the spy of Du Pont defends, model specification is Therma.
Preferably, by the thick 15mm that is densified to of 30mm, the unit weight of described superfine glass silk flosssilk wadding anti-noise layer is 12kg to described superfine glass silk flosssilk wadding anti-noise layer in construction.
Preferably, described heat-preservation cotton is two-layer structure, and the upper strata is heat preservation rock, and lower floor is glass wool.
Preferably, described glass wool sound absorbing layer, upper strata heat preservation rock and lower floor's glass wool are by the thick 30mm that is densified to of 50mm, and the unit weight of described glass wool sound absorbing layer is 12kg, and the unit weight of described upper strata heat preservation rock is 100kg, and the unit weight of described lower floor glass wool is 24kg.
Preferably, the surface density of described Al-Mg-Mn alloy roof panel is 3.4kg/ ㎡, the surface density of described supporting steel plate is 3.83kg/ ㎡, the surface density of described plasterboard is 9kg/ ㎡, the surface density of described interior lining panel is 4.7kg/ ㎡, the surface density of described superfine glass silk flosssilk wadding anti-noise layer, heat-preservation cotton and glass wool sound absorbing layer is 7.5kg/ ㎡, and the surface density of described support purlin is 5.6kg/ ㎡.
Preferably, described interior lining panel is surface spraying perforation profiled sheet, and perforated percentage is 21%, aperture 24mm.
Preferably, described water-proof air-permeable layer lap-joint adopts two-sided butyl rubber belt to bond continuously.
The present invention arranges the twice waterproof construction and carries out waterproof, namely below the Al-Mg-Mn alloy roof panel, be provided with the secondary waterproofing course, this secondary waterproofing course adopts highdensity spunbond polyethylene nonwoven water-proof air-permeable layer, the combination of rigid waterproof layer and lower floor's flexible waterproof layer like this can be satisfied waterproof and not hinder ventilative again.
In addition, secondary waterproofing course clinch adopts two-sided butyl rubber belt that lap belt is bondd continuously, has avoided the infiltration of secondary waterproofing course clinch.
Because multilayer sandwich sheet structure can be obtained better defening effect than individual layer sheet material, so the present invention is provided with four laminates.Except the Al-Mg-Mn alloy roof panel and undermost interior lining panel of top layer, also be provided with one supporting steel plate in the centre; Make the sound insulation thick gypsum plank of 12mm together.
The multi-layered board sound insulating structure is the same with individual layer sheet material, can produce coincidence effect equally, and critical frequency depends on the critical frequency of the lamina of forming multi-layered board.When the double-deck sound insulating structure that two identical individual layer sheet materials are combined into, because both critical frequencies are identical, this frequency has a large amount of acoustic energy and sees through, thereby makes the identical paddy of sound insulation descend the recessed intensification of sound insulation frequency curve greatly.Generally adopt the different lamina of thickness to form double-deck sound barrier equipment structure for commaterial, so that both coincidence frequencies stagger.So four set laminate materials of the present invention, every laminate material has different surface densities.The surface density of the superiors' aluminium alloy plate is 3.4kg/ ㎡, and the intermediate layer steel plate is 3.83kg/ ㎡, the about 9kg/ ㎡ of gypsum plank surface density, and lower floor is 4.7kg/ ㎡.
The present invention at first adopts solid-borne sound sound insulation measure, by increasing the damping action of plate, improve the sound insulation factor of coincidence frequency, thereby the paddy that coincide is shoaled, namely at the bottom of roof panel, lay the thick superfine glass cotton material of 30mm, then by in design and construction, glass wool being compressed to 15mm, thereby make not only to be adjacent between plate and the glass wool but also to have and form certain pressure, so just be equivalent to paste one deck damping material at the bottom of plate, by evidence, this kind way can effectively lower the solid-borne sound noise.
In addition, the present invention is in the punching of roof construction orlop interior lining panel, and perforation steel sole plate and heat-preservation cotton constitute the sound-absorbing structure jointly, and test detects proof, and sound-absorption coefficient surpasses 0.85, satisfies building to the requirement of roof sound absorption qualities.
To sum up, the present invention takes solid sound insulation at the roof skin, attracts structure and adopt at the roof internal layer, and final like this to have avoided outdoor noise to pass to indoor.
And because the present invention arranges moistureproof vapour-binding film below heat-preservation cotton, can stop indoor water vapour in enclosed structure, to permeate, thereby effectively guarantee thermal property and the durability of structures of heat-preservation cotton.And the moistureproof design characteristic of this engineering is, when every the vapour layer and as for the supporting use of water-proof air-permeable film above the insulation layer, can make roofing obtain the isolated effect of excellent steam, and its internal steam can be discharged smoothly, thereby perfectly solve moistureproof problem.
