浅析外墙保温系统的总体要求
来源: 日期:2018-08-23 发布人:admin

1、保温效果

1, insulation effect

保温效果是外墙外保温质量的一个关键性指标。所以应采用满足当地节能设计标准的保温材料,在施工过程中严格控制施工工艺,避免产生局部热桥现象。

The thermal insulation effect is a key index of the external thermal insulation quality of the external wall. Therefore, the insulation materials which meet the local energy-saving design standards should be used to strictly control the construction process in the construction process to avoid local thermal bridge phenomenon.

2、稳定性

2. Stability

与基层墙体牢固结合,是保证保温层稳定性的基本环节。对建筑物面层要仔细检查,如果面层存在空鼓、疏松情况,必须认真清理,以确保保温层与墙体紧密结合。外墙外保温体系应能抵抗当地最不利的温度与湿度条件下、承受风力、自重及正常碰撞等各种内外力相结合的负载,在如此严酷的条件下,保温层仍不与基底分离、脱落。

Solid combination with the base wall is the basic link to ensure the stability of the thermal insulation layer. The building surface should be carefully inspected, if the surface is empty and loose, it must be carefully cleaned to ensure that the insulation layer and the wall closely combined. Exterior wall insulation system should be able to withstand the most adverse local temperature and humidity conditions, withstand wind, gravity and normal collision and other internal and external forces combined with the load, in such a harsh condition, the insulation layer is still not separated from the base, fall off.

3、防火性能

3. Fire resistance

尽管保温层处于外墙外侧,防火处理仍不容忽视,在采用B级材料做外保温材料时,必须采用有阻燃性能的板材,应采用燃烧性能为A级的材料在每层设置水平防火隔离带。

Although the insulation layer is outside the wall, the fire prevention treatment can not be ignored. When using B-grade material as the external insulation material, it is necessary to use flame retardant sheets. A-grade material should be used in each layer to set a horizontal fire prevention isolation belt.

4、湿热性能

4. Hygrothermal performance

外保温墙体面层、接缝处、孔洞周边、门窗洞口周围等处,应采取严密的措施,使其具有良好的防水性能。

Strict measures should be taken to ensure good waterproofing performance in the surface layer, joints, periphery of holes, doors, windows and entrances of external insulation wall.

5、温度效应

5. Temperature effect

外墙外保温墙体应能耐受当地最严酷的气候及其变化。无论是高温还是严寒的气候,都不应使外墙外保温体系产生不可逆的损害或变形。为避免表面温度的变化产生的变形使表面出现裂纹,应设置伸缩缝。在门窗口、边角处、穿墙管等部位,为避免墙体变形及抹灰接缝处产生裂纹,应采取措施。

External wall insulation should be able to tolerate the most severe climate and changes in the area. No matter in high temperature or cold climate, it should not cause irreversible damage or deion of external wall insulation system. To avoid deion caused by the change of surface temperature, cracks should be set on the surface. In order to avoid wall deion and cracks at plastering joints, measures should be taken at doors, windows, corners and through-wall pipes.

6、耐撞击性能

6. Impact resistance

外墙外保温体系应能耐受正常的交通往来的人体及搬运物品产生的碰撞。在经受一般性偶然或者故意的碰撞时,不至对外墙外保温体系造成损害。在安装空调器时或用常规方法放置维修设施时,面层不至开裂或者穿孔。

The external thermal insulation system should be able to withstand the collision between normal traffic and the moving objects. When subjected to general accidental or intentional collisions, it does not cause damage to external insulation systems. When installing air conditioners or placing maintenance facilities by conventional methods, the surface will not crack or perforate.

7、抗变形能力

7, anti deion ability

受主体结构变形的影响,当主体结构产生正常变形时(收缩、徐变、膨胀等),外墙外保温体系应不至于产生裂纹或者开裂。

Influenced by the deion of the main structure, when the main structure produces normal deion (shrinkage, creep, expansion, etc.), the external wall insulation system should not produce cracks or cracks.

8、耐久性

8, durability

外墙外保温体系的各种组成材料,应该具有化学的与物理的稳定性。所有的材料具有的性能,应做到在结构正常的使用寿命条件下,由于干燥、潮湿、电化腐蚀,以及昆虫、真菌或藻类的生长、动物的破坏等侵袭,都不至造成损害。所有材料之间彼此相容。

Various components of external thermal insulation system should have chemical and physical stability. The properties of all materials should be kept in the normal service life of the structure conditions, due to dry, humid, electrochemical corrosion, as well as insects, fungi or algae growth, animal damage and other invasion, do not cause damage. All materials are compatible with each other.
