墙体线槽防裂体系及其施工方法
摘要：
本发明公开了一种墙体线槽防裂体系及其施工方法，所述的防裂体系由快速填缝材料、耐碱玻纤网格布和柔性抗裂胶泥组成，所述的快速填缝材料包括以下重量份数的原料：特种水泥35‑50 份，石英砂40‑60 份，纤维素醚0.3‑0.5 份，淀粉醚0‑0.2 份，缓凝剂0.2‑0.5 份，可再分散乳胶粉1‑5份；所述的柔性抗裂胶泥包括液料组分和粉料组分。其施工方法：填缝修补；柔性抗裂胶泥的制备；柔性抗裂胶泥的批刮：待快速填缝材料硬化后即可进行柔性抗裂胶泥和耐碱玻纤网格布的施工，将搅拌好的柔性抗裂胶泥直接批刮于线槽处表面并压入耐碱玻纤网格布即可。本发明防裂效果良好，施工工艺简单，施工速度快，大大节约了施工成本。
摘要（英）：

The invention discloses a wall line slot crack prevention system and a construction method thereof. The crack prevention system is formed by a quick gap filling material, alkali resistant glass fiber gridding cloth and flexible anti-crack daub, wherein the quick gap filling material contains the following raw materials in parts by weight: 35-50 parts of special cement, 40-60 parts of quartz sand, 0.3-0.5 part of cellulose ether, 0-0.2 part of starch ether, 0.2-0.5 part of a retarder and 1-5 parts of re-dispersible latex powder; and the flexible anti-crack daub contains a liquid component and a powder component. The construction method comprises the following steps: performing gap filling repair; preparing the flexible anti-crack daub; performing batch scraping on the flexible anti-crack daub, namely performing construction on the flexible anti-crack daub and the alkali resistant glass fiber gridding cloth after the quick gap filling material is hardened, directly performing batch scraping on the stirred flexible anti-crack daub on the surface of the line slots, and pressing into the alkali resistant glass fiber gridding cloth. The crack prevention effect is excellent, the construction process is simple, the construction speed is high, and the construction cost is greatly saved.
