Abstract
A thermal retardation nail can prevent the inner cold quantity in a building with a light steel roof thermal retardation which adopts a mechanical fixing system to be massively lost. The present invention is composed of a thermal retardation protective sleeve, a thermal retardation expansion sleeve, a thermal retardation expansion core, a metal pressing sheet and a metal screw. The thermal retardation nail minifies the metal sheet to 20 percent of the commonly used metal sheet by utilizing the design characteristic that the metal pressing sheet and the thermal retardation expansion sleeve base seat structure are mutually meshed. The thermal retardation nail can reach stronger thermal retardation effect by utilizing the thermal retardation expansion sleeve and the thermal retardation expansion core to effectively separate the metal screw from the indoor objects, and simultaneously the advantage that the area of the metal pressing sheet is smaller than the commonly used metal pressing sheet by 80 percent reaches better thermal retardation effect. The thermal retardation nail locks and fixes the metal thin plate between the big and the small convex rings through a protective sleeve, and is suitable for the wavy metal thin plates with the thickness of more than 0.35 mm, and the thickness of the wavy metal thin plate required by the screw fixing method is more than 0.75 mm, therefore the adaptability is strong.
Description
Affiliated technical field
The present invention relates to a kind of fastening piece of environmental protection and energy saving, can prevent that especially light-steel roofing from adopting the fastening piece of a large amount of losses of interior of building cold of mechanical fixation water-proof heat-insulation layer.
Background technique
Shown in Fig. 7 " metallic screw directly fixedly mounts schematic representation ", at present, the waterproof thermal-insulated mechanical fixation system of the light-steel roofing of Gong Rening directly is fixed on waterproof roll (14) and warming plate (17) on the Wavy metal thin plate (13) with metallic screw (5) and metal sheeting (4).Because warming plate compressive strength is lower, in order to compress waterproof roll, metal sheeting must strengthen seal face, has increased the metallic screw hot area in the middle of this is invisible.
Shown in Fig. 8 " metallic screw directly fixedly heat conduction figure ", because Wavy metal thin plate heat diffusion area is big, its wave mode structure is equivalent to a large-scale radiator, thereby the Wavy metal thin plate increased the metallic screw heat diffusion area, and the very fast quilt of heat that imports into through metallic screw dissipates and makes that the indoor end temperature of metallic screw is lower; And outdoor because metal sheeting has big hot area, metal sheeting is passed to metallic screw with a large amount of heats, makes a large amount of heat accumulations of the outdoor end of metallic screw cause temperature higher like this.
Otherwise if do not have heat absorption of metal sheeting large size and the heat radiation of Wavy metal thin plate large size, the temperature difference at metallic screw two ends is less.In sum, because mechanical fixation system structure defective itself causes metallic screw two ends high temperature difference, according to the transmission of heat formula, the heat of same object conduction is directly proportional with the object two ends temperature difference, and the temperature difference is high more, and the heat of conduction is just many more.Therefore, outdoor heat by mechanical fixation system conduction is directly to conduct tens times of heat by the metallic screw that corresponding no metal sheeting links to each other with the Wavy metal thin plate, and the fastening piece that every square metre of roofing is made up of metallic screw and metal sheeting tens covers is fixed on the Wavy metal thin plate, like this in the chamber, internal-external temperature difference increased by about 17% energy consumption when being 5 ℃.Because the temperature difference is big more, the energy consumption curve rate is high more, so in the chamber, internal-external temperature difference increased by about 46% energy consumption when being 10 ℃.
Shown in Fig. 9 " no jacket expansion pipe schematic representation ", Wavy metal thin plate (13) is generally formed by the compacting of 0.4mm-1mm sheetmetal, and the sidewall of boring back perforate in the above is equivalent to a sharp sword.The expansion tube made from nonmetallic material (18) is being squeezed by metallic screw (4) that the surface can be scratched by sheetmetal in the inflation process, is isolating and produce damage surface (19), serious causes expansion tube to be broken to cause mechanical fixation to lose efficacy.Moreover metallic screw is passed to heat indoor by inflation openings gap (20).
Summary of the invention
In order to overcome the weakness of the waterproof thermal-insulated mechanical fixation system heat insulating ability of existing light-steel roofing difference, the invention provides a kind of bar for line, this bar for line can not only be stopped substantially by metallic screw conduction heat, and can increase the intensity and the withdrawal resistance of mechanical fixation system.Adopt the fastening piece of this bar for line, can reduce by about 16.5% energy consumption in the chamber, when internal-external temperature difference is 5 ℃, when the indoor and outdoor temperature difference is 10 ℃, can reduce by about 45% energy consumption as the waterproof thermal-insulated mechanical fixation system of light-steel roofing.
The technical solution adopted for the present invention to solve the technical problems is:
