Abstract
The invention discloses a steel structure cold-bridge-preventing roof system. The system comprises a lower layer plate and an upper layer plate which are paved on a purline, and heat preservation cotton arranged between the upper layer plate and the lower layer plate, wherein an anti-compression bracket with a vertical supporting wall is also arranged between the upper layer plate and the lower layer plate, and the position of the anti-compression bracket corresponds to the position of the purline; the extension direction of the anti-compression bracket is consistent with that of the purline; and the width of the anti-compression bracket perpendicular to the purline is smaller than that of the upper layer plate perpendicular to the purline. The heat preservation cotton in the whole steel structure cold-bridge-preventing roof system is changed with the shape of a roof plate through the anti-compression bracket, and is uncompressed, so that the hidden danger of a cold bridge caused by the compression of the heat preservation cotton is eliminated.
Description
Technical field
The present invention relates to a kind of Roof system, relate in particular to the anti-cold bridge Roof system of a kind of steel work.
Background technology
Steel work be with economic steel profile member as bearing skeleton,, mainly be by the support frame system, go along with sb. to guard him shell system, lightweight body of wall, decorative exterior wall, roof and door and window and constitute as the building that space enclosing structure was constituted with light-weight walling material.Because advantages such as the structural steelwork construction speed is fast, industrialization degree is high, economic, suitable are used widely in building trade especially lightweight steel construction factory building; But from heat insulation effect; Reasons such as lightweight steel construction factory building insulation design of node defective and material self contraction have been destroyed the integrality of separated vapour layer and insulation layer in the space enclosing structure, hot gas by indoor to outdoor infiltration; Run into cold air and form condensed water, these positions are called " cold bridge ".Therefore need carry out structure design through node and handle, cut off the media conductor that produces " cold bridge ", the indoor and outdoor temperature difference can't effectively be transmitted reach heat insulation effect, thereby eliminate the generation of dewfall phenomenon with structure to the cold bridge position.
In the steel work containment system; Existing clad steel plank house (wall) face generally is made up of roofing top plate, heat-preservation cotton, roofing lower plywood matching and fixing seat and purlin; Its erection sequence is to lay earlier the roofing lower plywood, secondly be to lay heat-preservation cotton, again with the holder bolt on purlin; Last roofing top plate utilization lock seaming technology is connected with holder, realizes the fixed installation of clad steel plank house (wall) face.But in above-mentioned mounting means, the compression of heat-preservation cotton must occur in the junction of holder and purlin, cause here the heat insulating ability difference or almost have no heat-insulating property.Particularly when steel building is applied in north China, because winter temperature is cold, the lowest temperature is many at-5 ° below the C; So; Indoor/outdoor temperature-difference is bigger, and relative humidity is high, under this environment; Very easily produce large-area condensation and dewfall in heat-preservation cotton compression place, when serious fall short of success for lack of final effort in whole roof.
On the theory; The building interior surface temperature will produce condensed water so long as be lower than the place of dew point; The heat insulating material effective thickness at any position is lower than the thinnest numerical value in the insulation layer; Therefore interior surface temperature will be lower than dew point, wants to guarantee that building has good heat-insulating property and will farthest reduce the influence that holder and purlin push heat-preservation cotton.
For this reason; Chinese patent document CN2903227Y discloses the embedded anti-cold bridge insulation construction of a kind of metal die plank house face; It comprises the glass wool that is laid on the purlin and presses and put the metal crimp template on glass wool that support between metal crimp template and purlin and the insulation cushion block that is fixedly connected with support are embedded in the glass wool, is embedded in interior support of glass wool and support cushion block with supporting between metal crimp template and the purlin; The support of this prior art Rational Thickness and heat insulating block; Remedied the influence of support and purlin to a certain extent, but because the insulation cushion block is embedded in the glass wool, still there is the phenomenon that is extruded in the heat-preservation cotton between heat insulating block and the lower plywood to the heat-preservation cotton extruding; And if the insulation cushion block remedies the influence that support and purlin push heat-preservation cotton fully; The insulation cushion block need use extruded sheet in work progress, but extruded sheet is fireproof not as reproducing article of oil, and present country has forbidden extruded sheet is used for civilian construction; And its heat insulation effect of insulation cushion block of other material can not remedy the influence to the heat-preservation cotton extruding of support and purlin fully all not as good as the heat insulation effect of heat-preservation cotton.Therefore, the technology that adopts the document to put down in writing still can't be brought into play the maximum heat insulation effect of heat-preservation cotton.
Summary of the invention
The technical problem of solution according to the invention is the phenomenon that there is compression in heat-preservation cotton in the prior art; Therefore the invention provides a kind of heat-preservation cotton does not have the anti-cold bridge Roof system of steel work of compression; Thereby the Roof system heat-insulating property is reached unanimity, avoid cold bridge dewfall phenomenon because of heat-preservation cotton generation in uneven thickness.
