Description

一种织物混凝土砌块及制备方法 技术领域
本发明属于土木建筑工程和装配结构领域，涉及建筑砌体材料，具体为一种织物混凝土砌块及制备方法。
背景技术
砌块是建筑物墙体的组成材料之一，具有制作、运输和砌筑优势。建筑物墙体一般需承受面内和面外荷载，具有保温、隔声、隔振、抗冻的功能，耐久实用。正常使用时不得出现裂缝，墙体应方便开设门窗洞口，敷设各类管线。
现有加气混凝土砌块和轻集料砌块具有保温隔声的功能，但由于内部封闭气孔较多，砌块强度较低，外观多有蜂窝麻面，搬运中易出现缺棱掉角，吸水率高、抗冻性差；表面抹灰易出现空鼓、掉灰、裂缝的通病，墙体极易开裂，严重影响使用。
发明内容
针对现有技术中存在的问题，本发明提供一种织物混凝土砌块及制备方法，砌块抗压强度高，无孔洞麻面，外观质量好，墙体附着能力强，能够抑制墙体裂缝，延长墙体寿命，使其与主体结构使用年限匹配。
本发明是通过以下技术方案来实现：
一种织物混凝土砌块，包括布置形成矩形筒棱角的四个L形角条，张紧缠绕固定在L形角条外部形成矩形筒状结构的织物外壳，以及填充在织物外壳内部的填料。
优选的，所述的织物外壳由帆布、有机纤维或无机纤维缠绕形成。
优选的，所述的填料呈空心设置。
进一步，所述的填料的空心部分呈圆柱状，且与矩形筒状结构同轴设置。
进一步，所述的填料的空心部分填充有保温材料。
优选的，所述的填料采用加气混凝土，轻集料混凝土或高性能混凝土。
一种织物混凝土砌块的制备方法，包括如下步骤，
步骤1，织物外壳制备；
步骤1.1，准备一个芯筒，芯筒横截面尺寸略小于砌块横截面尺寸，芯筒长度与砌块长度相同；
步骤1.2，在芯筒四个棱边固定L形角条，在L形角条外侧涂刷环氧树脂与固化剂混合物；
步骤1.3，将织物起始边粘贴于芯筒棱边的L形角条一个面，将织物张紧环绕芯筒一周后粘贴于同一棱边的L形角条的另一个面；待环氧固化后取出芯筒，完成织物外壳制备；
步骤2，织物外壳内部填料；
步骤2.1，将织物外壳放入钢模中，织物外壳用卡扣法临时固定在钢模底部以保持形状；钢模横截面内部尺寸等于织物外壳横截面外部尺寸，二者长度相同；
步骤2.2，在织物外壳内部浇筑填料；加压振捣密实，使得织物贴合钢模内壁；
步骤3，养护成型；养护至填料初凝，拆除钢模，继续养护至填料完全凝固，完成砌块制作。
进一步，步骤1.1中，在芯筒外包裹一层塑料薄膜。
进一步，步骤2.1中，钢模上开设若干小孔，用于织物外壳内填料的自由水外排。
进一步，步骤2.1中，在织物外壳中心放置圆管，在织物外壳内和圆管外浇筑填料，形成空心腔体。
与现有技术相比，本发明具有以下有益的技术效果：
本发明利用织物具有透水性好的特点，从而能够降低织物附近的水灰比， 增大混凝土密度，从而提高砌块强度，降低吸水率，提高抗冻性和保温性能。通过张紧环绕形成的织物外壳施加一定预应力，依靠织物自身张拉作用能够防止混凝土开裂，并提供环向约束，形成“环箍效应”，进一步提高砌块的抗压强度。并且由于织物本身为热惰性材料，具有保温隔热功能，配合填料进一步提升墙体热工性能。由于织物具有一定韧性，因此墙体具有减震隔振的功能，可以消减结构振动对用户的干扰，提升舒适性。织物具有抗拉能力，采用粘结力较强的砌筑材料时墙体具有良好的抗冲击和抗裂性能，从而彻底解决砌块墙体开裂问题。从而使得砌块具有水分呼吸功能，可用于调节室内湿度，改善舒适度。由于织物包裹，砌块外观质量良好，无蜂窝麻面，缺棱掉角，可以直接刷涂料使用，特别适用于装配式结构。织物砌块墙体整体性好，可以开线槽，铺设管线，可钻孔打眼，内贴外挂，便于使用。通过设置的L形角条，一方面作为织物外壳的骨架，另一方面能够对砌块的棱边进行定位和保护。
进一步的，织物与混凝土中的砂浆粘接性极好，吸附力墙，且能够吸水保水，可避免界面剂的使用，降低成本，简化施工；织物与混凝土/砂浆粘结力强，温度作用下同伸缩，有效避免温度裂缝。混凝土为不燃烧体，织物内浇筑混凝土后为难燃烧体，提高墙体的抗火性能。
进一步的，由于采用轻质填料，配合织物，或空心措施，砌块重量轻，有利于搬运和砌筑，同时减少地震作用惯性力，减轻震害，降低墙体外闪和塌落风险。
本发明所述的方法，通过织物从外围包裹内部填料，通过张紧环绕施加一定预应力，依靠织物自身张拉作用防止混凝土开裂，并提供环向约束，形成“环箍效应”，又进一步提高砌块的抗压强度。由于钢模成型，确保砌块尺寸精准，进而在砌筑过程中减少灰缝厚度，防止热桥形成，大幅改善墙体的保温隔热功能。取材方便，制作简单，成本低，效率高，性能优良，可工 厂预制现场砌筑，亦可现场预制现场砌筑。
