Abstract
The invention discloses a construction method for a compound glass wool board air pipe, which adopts lining flange connection to successfully avoid cold-heat bridge cutoff easily caused at the joint of a traditional flange butting air pipe, and eliminates condensation and moldiness. Inner air pipe supports and lining flange connectors are trusses composed of flat steel and round steel with reinforcing ribs (grooves), and the strength problem of the compound glass wool board air pipe is conveniently solved, so that consumption of steel in connection of the air pipe is reduced, and accessory cost is reduced. Galvanized hanger rods are directly welded on the lining flange connectors, hanger cross arms are completely not needed, and reinforcement aluminum foils are directly pasted outside air pipe joints, so that the appearance of the air pipe is continuous, smooth, square, attractive and elegant, and various requirements of open installation, concealed installation and the like can be met.
Description
Technical field
The invention belongs to pipeline, relate in particular to a kind of construction method for compound glass wool board air pipe.
Background technology
From the mid-90, composite glass wool board air duct is promoted and is come gradually in China from heavy and light, advantage that cost is low with it.Traditional composite glass wool board air duct adopts angle steel enamel orchid or the blue joint of steel plate enamel, inner support adopts many single rod supporteds, outer hanging adopts angle steel or special type light steel cross-arm backing, reinforcing bar suspending way, exists cold-heat bridge dewfall, mouldy, outward appearance to be in disorderly not suitable for bright dress, can not adapt to the problems such as larger cross-section size.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of simple in structure, adopt lined flange to connect, the cold and hot bridge cut-off phenomenon of having avoided airduct easily to produce at connecting portion, has stopped dewfall, Signs of Mould.
The present invention is achieved by the following technical solutions:
A kind of construction method for compound glass wool board air pipe, comprises the following steps:
1) by bonding tight to airduct chine and closed line, without cracking gap, tube wall is without hole, and tight with aluminum foil and adhesive tape stickup, length of tube direction is without splicing seams with the wind;
2) when airduct width is greater than 1 meter while being less than 1.6 meters, every joint airduct is established 1 secondary inner support; In the time that airduct width is greater than 1.6 meters, every joint airduct is established 2 secondary inner supports, all perforation tight shutoff of sealant tape for seam on airduct tube wall;
3) end of airduct and lined flange connector overlap joint, overlapping part is tightly bonding with glue, between its inner side and lined flange connector, nails on firm compacting with plastic, thermal-insulation;
4) on lined flange connector framework, be welded with externally threaded steel circle, transversely welding in pairs;
5) flame-proof glass fibre glue is completely smeared in framework outside, composite glass wool board is pasted on framework, in the screw of airduct inner side insertion lined flange connector, penetrate composite glass wool board with awl, then bar for line is shot hole from the back side along hole, after 24 hours, reached intensity.
In the time that the maximum hem width degree of airduct is greater than 6000mm, longitudinally going up of four angles of liner of steel lined flange connector, adopts the light-duty angle bar of inequilateral of 40mm × 60mm to do longitudinal connection, joint welding; Wherein long limit 60mm is for facade, and minor face 40mm is for plane; In the time longitudinally having connected, every 600mm arranges a steel lined flange connector, forms integral lining framework, is inside lining with reinforcement convex surface inwardly.
When airduct wide or tall and big is during in 2950mm, to there is in the vertical a piece, between liner, adopt and longitudinally weld lead-in in the preceding paragraph steel, make to be lining with in piece steel in the vertical fixing, in piece, stick with glue and connect with the interior lead-in contact-making surface of longitudinal steel with airduct, add plastics self tapping bar for line again, then use aluminum foil and adhesive tape veneer, now joint face can be considered a leveling face.
Advantage of the present invention is: be that lined flange connects by traditional flange to air duct Innovation of Connection, the cold and hot bridge cut-off phenomenon of successfully having avoided conventional flange easily to produce at connecting portion air duct, has stopped dewfall, Signs of Mould.Band steel and the round steel composite roof truss of band reinforcement (groove) for airduct inner support and lined flange connector, conveniently solved the strength problem of composite glass wool board air duct, thereby reduced rolled steel dosage when airduct connects, and reduced auxiliary material cost.Zinc-plated suspension rod is directly welded on lined flange connector, does not need suspension bracket cross-arm completely, duct collar is outer directly pastes and adds reinforced aluminium foil, makes the outward appearance of airduct continuous, smooth-going, upright, elegant in appearance, can adapt to the various needs such as bright dress and concealed installation.
Detailed description of the invention
Embodiment: a kind of construction method for compound glass wool board air pipe, comprises the following steps:
1) by bonding tight to airduct chine and closed line, without cracking gap, tube wall is without hole, and tight with aluminum foil and adhesive tape stickup, length of tube direction is without splicing seams with the wind;
2) when airduct width is greater than 1 meter while being less than 1.6 meters, every joint airduct is established 1 secondary inner support; In the time that airduct width is greater than 1.6 meters, every joint airduct is established 2 secondary inner supports, all perforation tight shutoff of sealant tape for seam on airduct tube wall;
3) end of airduct and lined flange connector overlap joint, overlapping part is tightly bonding with glue, between its inner side and lined flange connector, nails on firm compacting with plastic, thermal-insulation;
4) on lined flange connector framework, be welded with externally threaded steel circle, transversely welding in pairs;
5) flame-proof glass fibre glue is completely smeared in framework outside, composite glass wool board is pasted on framework, in the screw of airduct inner side insertion lined flange connector, penetrate composite glass wool board with awl, then bar for line is shot hole from the back side along hole, after 24 hours, reached intensity.
In the time that the maximum hem width degree of airduct is greater than 6000mm, longitudinally going up of four angles of liner of steel lined flange connector, adopts the light-duty angle bar of inequilateral of 40mm × 60mm to do longitudinal connection, joint welding; Wherein long limit 60mm is for facade, and minor face 40mm is for plane; In the time longitudinally having connected, every 600mm arranges a steel lined flange connector, forms integral lining framework, is inside lining with reinforcement convex surface inwardly.
When airduct wide or tall and big is during in 2950mm, to there is in the vertical a piece, between liner, adopt and longitudinally weld lead-in in the preceding paragraph steel, make to be lining with in piece steel in the vertical fixing, in piece, stick with glue and connect with the interior lead-in contact-making surface of longitudinal steel with airduct, add plastics self tapping bar for line again, then use aluminum foil and adhesive tape veneer, now joint face can be considered a leveling face.
