保温装饰板出现裂缝的原因有哪些
来源:/ 日期:2018-10-20 发布人:admin

面对目前国内外常使用的保温材料墙面产生裂缝的原因作出分析:

This paper analyzes the causes of cracks on the walls of insulation materials commonly used at home and abroad.

1.内保温板缝造成裂缝

1. internal insulation cracks caused cracks

不少施工单位为减少湿作业,选用粘贴预制板作法,但这种贴板法在施工若干月至一年后,多数面层都出现了不同程度的开裂,板接缝尤为明显,其原因

In order to reduce wet operation, many construction units choose sticking prefabricated board method. But after several months to one year of construction, most of the surface layers have cracked to different degrees, especially the joint of the board, and the reasons are obvious.

是外墙结构暴露在大气中受温度差变化影响结构整体外形尺寸发生变化,而附在外墙内侧的保温板都单独地收缩和膨胀,由此产生墙体与保温块材体型变化的应力方

It is the stress side of the wall and the insulation block that the overall shape and size of the structure change when the external wall structure is exposed to the atmosphere and affected by the temperature difference, and the insulation plate attached to the inside of the external wall shrinks and expands separately.

A1级防火保温材料

向和大小不同,各部分的这种变化随温度升降而轮回出现,因此容易造成裂缝。

The direction and size of the different parts of this change with temperature rise and fall and recurrence, so easy to cause cracks.

2.内保温浆料面层抗裂材料不配套造成的裂缝

2. crack of internal thermal insulation slurry without surface crack resistant material.

由于浆体保温材料施工方式是现场抹灰,它随建筑物形状而成型,可满足曲线弧线和不规则混凝土墙面的施工,可减少其层的剔补量,方便施工操作,是建筑业大量选用的材料。

Because the construction method of slurry insulation material is plastering on the spot, it is shaped with the shape of the building, can satisfy the construction of curved curve and irregular concrete wall, can reduce the amount of its layer, convenient construction operation, is a large number of materials selected by the construction industry.
