文章发布: 发表时间:2017-07-18 10:23:27

据了解,跟着对节约能源与维护环境的请求的不断提高,修建维护构造的保温技能也在日益加强,尤其是外墙保温技能得到了长足的开展,并变成我国一项首要的修建节能技能,不容忽视。

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.
现在,在济南彩钢板房中常运用的外墙保温首要有内保温、外保温、表里混合保温等办法,可是,在不一样的保温办法施工过程中,也呈现了各种各样的质量问题,这篇文章意在经过对上述三种保温办法发生的问题进行剖析,然后对工程中的质量问题起到防止的效果。
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.
外墙内保温
Exterior wall insulation
外墙内保温即是外墙的内侧运用苯板、保温砂浆等保温材料 ,然后使修建到达保温节能效果的施工办法。该施工办法具有施工便利,对修建外墙笔直度请求不高,施工进度快等长处。这些年,在工程上也常常的被选用。可是,外墙内保温所带来的质量问题也随之而来。
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.
外墙内保温的一个显着的缺点即是:构造冷(热)桥的存在使有些温差过大致使发生结露景象。因为内保温维护的方位只是在修建的内墙及梁内侧,内墙及板对应的外墙有些得不到保温材料的维护,因而,在此有些构成冷(热)桥,冬天室内的墙体温度与室内墙角(保温墙体与不保温板交角处)温度差约在10℃左右,与室内的温度差可到达15℃以上,一旦室内的湿度条件合适,在此处即可构成结露景象。而结露珠的浸渍或冻融及易形成保温隔热墙面发霉、开裂。
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,室内温度随日夜和时节的改变起伏一般不大(约10℃左右),这种温度改变导致修建物内墙和楼板的线性变形和体积改变也不大。可是,外墙和屋面受室外温度和太阳辐射热的效果而导致的温度改变起伏较大。当室外温度低于室内温度时,外墙缩短的起伏比内保温隔热系统的速度快,当室外温度高于室内气温时,外墙胀大的速度高于内保温隔热系统,这种反复形变使内保温隔热系统一直处于一种不稳定的墙体基础上,在这种形变应力反复效果下不仅是外墙易遭受温差应力的破坏也易形成内保温隔热系统的空鼓开裂。
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.
表里混合保温,是在济南彩钢板房 http://www.jnjinrun.com/ 的施工中,外保温施工操作便利的部位选用外保温,外保温施工操作不便利的部位作内保温,然后对修建保温的施工办法。
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.
从施工操作上看,混合保温可以提高施工速度,对外墙内保温不能维护到的内墙、板同外墙交接处的冷(热)桥有些进行有用的维护,然后使修建处于保温中。可是,混合保温对修建构造却存在着严重的危害。外保温做法部位使修建物的构造墙体首要受室内温度的影响,温度改变相对较小,因而墙体处于相对稳定的温度场内,发生的温差变形应力也相对较小;内保温做法部位使修建物的构造墙体首要受室外环境温度的影响,室外温度动摇较大,因而墙体处于相对不稳定的温度场内,发生的温差变形应力相对较大。有些外保温、有些内保温混合运用的保温方式,使全部修建物外墙主体的不一样部位发生不一样的形变速度和形变尺度,修建构造处于愈加不稳定的环境中,经年温差构造形变发生裂缝,然后缩短全部修建的寿命。
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.
济南彩钢板房保温做法中选用表里保温混合运用的做法是不合理的,比作内保温的危害更大。
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.
外墙外保温
Exterior wall insulation
外墙外保温,是将保温隔热系统置于外墙外侧,使修建到达保温的施工办法。因为外保温是将保温隔热系统置于外墙外侧,然后使主体构造所受温差效果大起伏降低,温度变形减小,对构造墙体起到维护效果并可有用阻断冷(热)桥,有利于构造寿数的延长。因而从有利于构造稳定性方面来说,外保温隔热具有显着的优势,在可选择的情况下应首选外保温隔热。
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,因为外保温隔热系统被置于外墙外侧,直接承受来自自然界的各种因素影响,因而对外墙外保温系统提出了更高的请求。就太阳辐射及环境温度改变对其影响来说,至于保温层之上的抗裂防护层只要3mm~20mm,且保温材料 具有较大的热阻,因而在的热量相同的情况下,外保温抗裂维护层温度改变速度比无保温情况下主体外倾温度改变速度提高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,抗裂防护层的柔韧性和耐候性对外保温系统的抗裂功能起着要害的效果,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.
