| 一、外墙内保温构造特点 I. Characteristics of Insulation Structure in External Wall 不同于外墙外保温，外墙内保温体系是将保温材料设置在墙体内侧表面的，常用的材料有水泥珍珠岩板、聚苯乙稀板、充气石膏板、岩棉板或者保温砂桨等，在今天最常用的做法是先内抹一层保温砂柴，然后贴上硅质保温板，从而达到整个墙体的保温的目的。 Unlike the external wall insulation, the internal insulation system of the external wall is to set the insulation material on the inner and outer surface of the wall. The commonly used materials are cement perlite board, polyphenylene ethylene dilute board, inflatable gypsum board, rock wool board or thermal insulation paddle, etc. Today, the most commonly used method is to apply a layer of thermal insulation Sandwood first, and then paste a silica thermal insulation board. So as to achieve the purpose of insulation of the whole wall. 二、外墙内保温硅质板优缺点 2. Advantages and disadvantages of silica board for external wall and internal insulation 这种体系的优点是价格便宜，施工起来也很简单,但是也有一些不利的地方。由于是贴在墙体内侧,很多地方不能包裹得到,比如楼板、抗震柱、隔墙等,这些部位不能保温,便会产生热桥,还会出现结露、墙体生长霉斑等现象,很大程度影响美观；而且，由于整个节能保温材料覆盖于墙体的外表面，当外界温差过大时，节能材料容易温差过大而导致结露的状态，使整个墙体发生开裂。墙体受到外界的日夜温差影响，导致反复的热胀冷缩现象，这种现象的反复出现使得保温材料位于动态的状态，极易造成保温材料的损坏。 The advantage of this system is that it is cheap and easy to construct, but there are also some disadvantages. Because it is affixed to the inside of the wall, many places can not be wrapped, such as floors, seismic columns, partitions, etc., these parts can not be insulated, they will produce thermal bridges, condensation, wall mold growth and other phenomena, greatly affecting the beauty; moreover, because the entire energy-saving thermal insulation materials cover the outer surface of the wall, when the outside temperature. When the difference is too large, the energy-saving materials are prone to dew due to the excessive temperature difference, which makes the whole wall crack. The wall is affected by the temperature difference between day and night, which leads to the phenomenon of repeated thermal expansion and contraction. This phenomenon makes the thermal insulation materials in a dynamic state, and easily causes the damage of thermal insulation materials. |
