轻质复合墙板分复合墙板内、复合墙板外墙两种，目前以生产内墙为主，内墙厚有50mm、75mm、100mm 120mm 150mm五种规格。我们的墙板长度有2440mm、3000mm两种规格，宽度统一为610mm。厚度为50mm墙板主要用于商铺，75mm墙板主要用于写字楼及商住两用楼，100mm墙板主要用于各种建筑的分户墙。厚度为75mm内墙与传统120mm墙体加抹灰相比较,每建12沿长米墙体可增加1平方米实用面积。房间整体面积增加率为4—6%。也就是说100平方米住宅就可增加4.26平方米的使用面积。

Light composite wallboard can be divided into composite wallboard inner wall and composite wallboard outer wall. At present, the production of inner wall is mainly used. The thickness of inner wall has five specifications: 50mm, 75mm, 100mm, 120mm and 150mm. Our wallboard has two specifications: 2440mm and 3000mm in length and 610mm in width. 50mm thick wallboard is mainly used for shops, 75mm wallboard is mainly used for office buildings and commercial and residential buildings, and 100mm wallboard is mainly used for household walls of various buildings. Compared with the traditional 120mm wall with plastering, the 75mm thick inner wall can increase the practical area of 1 square meter for each 12 meter long wall. The increase rate of the overall area of the room is 4-6%. In other words, 100 square meters of residence can increase the use area of 4.26 square meters.

由于复合墙板的水灰比较大，后期的失水干缩也较大。这会造成两种现浇工程质量事故。一种是，当采用纤维水泥面板时，会因为后期浆体的硬化干缩，使泡沫混凝土与面板分离，出现墙体空鼓，敲击时墙体发空。

Due to the large water cement ratio of composite wallboard, the water loss and drying shrinkage in the later stage are also large. This will cause two kinds of quality accidents of cast-in-situ engineering. One is that when the fiber cement panel is used, the foam concrete will be separated from the panel due to the hardening and shrinkage of the slurry in the later stage, and the wall will be hollowed and the wall will be empty when knocking.

二种是，当不使用纤维水泥面板而采用模板浇注时，模板拆除后，复合墙板会随着泡沫混凝土的干缩而逐渐出现开裂。近年，有不少企业因上述质量问题而被罚款或返工。目前，我们已在工程实践中总结经验，通过技术创新解决了空鼓、干缩 问题。

The two is that when the fiber cement panel is not used and the template is poured, the composite wallboard will gradually crack with the drying shrinkage of the foam concrete after the template is removed. In recent years, many enterprises have been fined or reworked for the above quality problems. At present, we have summed up experience in engineering practice and solved the problems of hollowing and drying shrinkage through technological innovation.

必须确保其符合玻纤含量。玻纤在商品中的效果与钢筋在钢筋混凝土中的效果是相同的，缺乏像缺乏相同的钢筋玻璃的内容，不能达到增强的效果。如果不添加玻璃纤维，拉伸和水泥基产品的抗弯强度小于2兆帕，抗弯强度和商品脚玻璃含量可达6MPa。商品修建装修构件在使用进程中至少接受5种荷载(自重、风，地震，温度应力，干湿变型应力和其他外荷载)效应，如果达不到强度目标，将是非常不安全的。

It must be ensured that it meets the glass fiber content. The effect of glass fiber in commodity is the same as that of steel bar in reinforced concrete. Without the same content of steel bar and glass, the effect of reinforcement cannot be achieved. If glass fiber is not added, the flexural strength of tensile and cement-based products is less than 2 MPa, and the flexural strength and commercial foot glass content can reach 6 MPa. The commercial construction and decoration components will accept at least five kinds of load effects (self weight, wind, earthquake, temperature stress, dry and wet deformation stress and other external loads) in the process of use. If the strength target is not reached, it will be very unsafe.

复合墙板节省使用面积。安装隔墙板后，整个房屋的使用面积将会有所减少，因此我们在选择隔墙板时好优先考虑那些厚度小，强度高的板材，将使用面积的减少降低到低程度。例如在近几年济南旧房改造工程中，济南墙板市场上轻质夹芯隔墙板就被经常采用。复合墙板有较高的强度。墙板强度高，抗冲击，不易破损是隔墙材料的重要指标。这一点，石膏板就存在明显的不足，凡是石膏板隔墙，时间一久没有不出现破损的，无法作为长久性隔墙使用。

Composite wallboard saves use area. After installing the partition board, the use area of the whole house will be reduced. Therefore, when selecting the partition board, we should give priority to those plates with small thickness and high strength, so as to reduce the use area to a low degree. For example, in the reconstruction of old houses in Jinan in recent years, light sandwich partition boards are often used in Jinan wallboard Market. Composite wallboard has high strength. Wallboard has high strength, impact resistance and is not easy to be damaged. It is an important index of partition material. In this regard, gypsum board has obvious shortcomings. All gypsum board partitions that have not been damaged for a long time cannot be used as long-term partitions.

复合墙板在原有隔墙板价格基础上要稍贵些许，因为新型复合隔墙板表面的硅酸钙板不仅具有其他隔墙板产品不具备的良好隔声功能，同时还具有十分优越的防火隔热性能，1000摄氏度高温下，耐火极限超过3小时，而且不会散发任何有毒有害物质。在选用复合墙板前，深入各板材生产企业进行考察，了解其生产工艺、质量体系、材料临时堆放场地、企业生产能力，以板材各项指标都符合标准、有足够的板材晾晒时间、材料的干燥。要求板材生产企业在生产过程中采用专用的水性隔离剂而不要采用废机油。

The composite wallboard is slightly more expensive than the original partition board price, because the calcium silicate board on the surface of the new composite partition board not only has the good sound insulation function that other partition board products do not have, but also has very superior fire and heat insulation performance. Under the high temperature of 1000 ℃, the fire resistance limit exceeds 3 hours, and will not emit any toxic and harmful substances. Before selecting composite wallboard, go deep into each plate production enterprise to investigate its production process, quality system, temporary material stacking site and enterprise production capacity, so as to ensure that all indexes of the plate meet the standards, have sufficient plate drying time and material drying. Plate manufacturers are required to use special water-based isolating agent instead of waste engine oil in the production process.

基于实例总结轻质隔墙板防开裂做法1、结构和反坎阶段线管出地面位置需定位并固定，防止偏位。2、复合墙板工厂内直接完成管线、底盒预埋，避免后期开凿，墙板预留槽大小线管接头顺畅。3、采用顶部坐浆法，避免梁底拼接缝塞填不实导致开裂。4、复合墙板安装时需用激光扫平仪控制底盒标高。5、阴阳榫增大墙板间接触面。6、结构面和墙板面均预留50X3mm压槽，挂玻纤网缓和裂缝发展。7、墙板拼接面均双面涂刷界面剂，确保基层清洁。8、结构打凿必须在墙板安装前完成的。9、定期抽芯检测。

Summarize the anti cracking methods of light partition board based on examples. 1. In the stage of structure and anti sill, the line pipe out of the ground shall be positioned and fixed to prevent deviation. 2. The embedding of pipelines and bottom boxes shall be directly completed in the composite wallboard factory to avoid later excavation. The size of the reserved groove of the wallboard shall be smooth. 3. The top grouting method is adopted to avoid cracking caused by improper filling of the splicing joint at the beam bottom. 4. During the installation of composite wallboard, the elevation of bottom box shall be controlled by laser broom. 5. The yin-yang tenon increases the indirect contact surface of the wallboard. 6. 50x3mm pressure groove shall be reserved on the structural surface and wallboard surface, and glass fiber mesh shall be hung to ease the development of cracks. 7.
