探索:濟南彩鋼板房外墻保溫采暖技術

文章發布: 發表時間:2017-07-18 10:23:27

據了解,跟著對節約能源與維護環境的請求的不斷提高,修建維護構造的保溫技能也在日益加強,尤其是外墻保溫技能得到了長足的開展,并變成我國一項首要的修建節能技能,不容忽視。

It is understood that follow to save energy and environmental protection request continues to improve, building maintenance structure heat preservation skills are also increasing, especially in exterior wall insulation skills have been developed rapidly, and become China's first energy-saving construction skills, can not be ignored.
現在,在濟南彩鋼板房中常運用的外墻保溫首要有內保溫、外保溫、表里混合保溫等辦法,可是,在不一樣的保溫辦法施工過程中,也呈現了各種各樣的質量問題,這篇文章意在經過對上述三種保溫辦法發生的問題進行剖析,然后對工程中的質量問題起到防止的效果。
Now, the exterior often used in Ji'nan in the first steel housing insulation insulation, thermal insulation, insulation and other exterior mixing way, but not the same way in the insulation construction process, also appeared all kinds of quality problems, this article is intended to pass on the three insulation measures occurred problem analysis, then, to prevent the effect on the quality problems in engineering.
外墻內保溫
Exterior wall insulation
外墻內保溫即是外墻的內側運用苯板、保溫砂漿等保溫材料 ,然后使修建到達保溫節能效果的施工辦法。該施工辦法具有施工便利,對修建外墻筆直度請求不高,施工進度快等長處。這些年,在工程上也常常的被選用。可是,外墻內保溫所帶來的質量問題也隨之而來。
Exterior wall insulation is the inside of the outer wall, the use of benzene board, insulation mortar and other insulation materials, and then built to achieve insulation, energy saving effect of construction methods. The construction method has the advantages of convenient construction, low request for building exterior wall straightness and fast construction speed. These years are often chosen in engineering. However, the quality of the interior insulation brought about.
外墻內保溫的一個顯著的缺點即是:構造冷(熱)橋的存在使有些溫差過大致使發生結露景象。因為內保溫維護的方位只是在修建的內墻及梁內側,內墻及板對應的外墻有些得不到保溫材料的維護,因而,在此有些構成冷(熱)橋,冬天室內的墻體溫度與室內墻角(保溫墻體與不保溫板交角處)溫度差約在10℃左右,與室內的溫度差可到達15℃以上,一旦室內的濕度條件合適,在此處即可構成結露景象。而結露珠的浸漬或凍融及易形成保溫隔熱墻面發霉、開裂。
One of the notable drawbacks of interior insulation is that the presence of a cold (hot) bridge results in a slight difference in temperature that results in condensation. Because the internal insulation maintenance range only in the inner wall and the inner wall beam construction, interior wall board and the corresponding bit is not preserved, so this insulation material, some form of cold (hot) bridge, winter indoor wall temperature and indoor wall (wall insulation and insulation board to corner temperature difference) at about 10 degrees Celsius, and the indoor temperature difference can reach more than 15 DEG C, if the indoor humidity conditions are right here to form the condensation scene. The dip of dew or freeze thaw and easy to form heat preservation and heat insulation, metope mildew and cracking.
另外,在冬天采暖、夏季制冷的修建中,室內溫度隨日夜和時節的改變起伏一般不大(約10℃左右),這種溫度改變導致修建物內墻和樓板的線性變形和體積改變也不大。可是,外墻和屋面受室外溫度和太陽輻射熱的效果而導致的溫度改變起伏較大。當室外溫度低于室內溫度時,外墻縮短的起伏比內保溫隔熱系統的速度快,當室外溫度高于室內氣溫時,外墻脹大的速度高于內保溫隔熱系統,這種反復形變使內保溫隔熱系統一直處于一種不穩定的墻體基礎上,在這種形變應力反復效果下不僅是外墻易遭受溫差應力的破壞也易形成內保溫隔熱系統的空鼓開裂。
In addition, in the winter heating and summer cooling construction, indoor temperature and seasonal fluctuation change with day and night is generally small (about 10 degrees Celsius), the temperature change causes the linear deformation and volume change of building wall and floor is small. However, the temperature changes caused by the effect of outdoor temperature and solar radiation on the exterior wall and roof are larger. When the outdoor temperature is lower than the indoor temperature, exterior wall thermal insulation system to shorten the Binet rolling speed, when the outdoor temperature is higher than room temperature, wall swell faster than in the insulation system, the repeated deformation of the inside thermal insulation system has been in an unstable wall on the basis of the deformation stress repeatedly under the effect of exterior wall is not only vulnerable to thermal stress damage is easily formed in the insulation system cracking.
表里混合保溫,是在濟南彩鋼板房 http://www.xtzisha.com/ 的施工中,外保溫施工操作便利的部位選用外保溫,外保溫施工操作不便利的部位作內保溫,然后對修建保溫的施工辦法。
In the hybrid insulation, is in the construction of Ji'nan steel housing, external insulation construction convenient operation of the site selection of external insulation, external insulation construction operation is not convenient for the parts in the insulation, and then on the way of building insulation construction.
從施工操作上看,混合保溫可以提高施工速度,對外墻內保溫不能維護到的內墻、板同外墻交接處的冷(熱)橋有些進行有用的維護,然后使修建處于保溫中。可是,混合保溫對修建構造卻存在著嚴重的危害。外保溫做法部位使修建物的構造墻體首要受室內溫度的影響,溫度改變相對較小,因而墻體處于相對穩定的溫度場內,發生的溫差變形應力也相對較小;內保溫做法部位使修建物的構造墻體首要受室外環境溫度的影響,室外溫度動搖較大,因而墻體處于相對不穩定的溫度場內,發生的溫差變形應力相對較大。有些外保溫、有些內保溫混合運用的保溫方式,使全部修建物外墻主體的不一樣部位發生不一樣的形變速度和形變尺度,修建構造處于愈加不穩定的環境中,經年溫差構造形變發生裂縫,然后縮短全部修建的壽命。
From the construction operation, hybrid insulation can improve the speed of construction of interior wall, exterior insulation plate can not maintain the same wall at the junction between the cold (hot) some useful for bridge maintenance, then built in thermal insulation. But, the mixed thermal insulation has serious harm to the construction. The practice of external thermal insulation parts make the building structure of the primary wall affected by the indoor temperature, the temperature change is relatively small, so the wall in the temperature field is relatively stable, the temperature stress and deformation is relatively small; insulation practices part of the building wall structure mainly by the outdoor environment temperature, outdoor temperature greatly shaken, so the wall in the temperature field is not stable, the temperature stress and deformation is relatively large. In some ways the mixed use of some thermal insulation thermal insulation, and all the buildings are not the same as the part of outer wall body deformation rate and deformation is not the same scale, building structures in an increasingly unstable environment, a temperature difference of tectonic deformation cracks, and shorten the life of all construction.
濟南彩鋼板房保溫做法中選用表里保溫混合運用的做法是不合理的,比作內保溫的危害更大。
Ji'nan color steel board room insulation practices, the choice of internal and external insulation, mixed use of the practice is unreasonable, compared to the internal insulation of greater harm.
外墻外保溫
Exterior wall insulation
外墻外保溫,是將保溫隔熱系統置于外墻外側,使修建到達保溫的施工辦法。因為外保溫是將保溫隔熱系統置于外墻外側,然后使主體構造所受溫差效果大起伏降低,溫度變形減小,對構造墻體起到維護效果并可有用阻斷冷(熱)橋,有利于構造壽數的延長。因而從有利于構造穩定性方面來說,外保溫隔熱具有顯著的優勢,在可選擇的情況下應首選外保溫隔熱。
External wall insulation is to heat insulation system placed in the outer wall, so that the construction to reach insulation construction methods. Because the external insulation is placed outside of the external wall insulation system, then the main structure of the temperature effect of large fluctuation is reduced, reducing temperature, to maintain the effect and can be useful to construct walls blocking the cold (hot) bridge, the structure is beneficial to prolong life. Therefore, for the benefit of structural stability, the external thermal insulation has a significant advantage, in the choice of circumstances should be preferred insulation.
可是,因為外保溫隔熱系統被置于外墻外側,直接承受來自自然界的各種因素影響,因而對外墻外保溫系統提出了更高的請求。就太陽輻射及環境溫度改變對其影響來說,至于保溫層之上的抗裂防護層只要3mm~20mm,且保溫材料 具有較大的熱阻,因而在的熱量相同的情況下,外保溫抗裂維護層溫度改變速度比無保溫情況下主體外傾溫度改變速度提高8~30倍。
However, because the exterior heat insulation system is placed outside the outer wall, it is directly affected by various factors from the natural world. Therefore, a higher request is put forward for the exterior wall insulation system. The solar radiation and environmental temperature change on its impact, as for the insulation crack protective layer layer as long as 3mm~20mm, and the heat insulating material has larger resistance, so in the heat under the same external thermal insulation layer maintenance temperature changes faster than body temperature without insulation extraverted change speed is increased by 8~30 times.
因而,抗裂防護層的柔韌性和耐候性對外保溫系統的抗裂功能起著要害的效果,值得探究。
Therefore, the flexibility and weather resistance of the anti cracking protective layer play a crucial role in the anti cracking function of the external thermal insulation system, which is worth exploring.
