Description

一种预制断热桥复合保温条板及其制作方法
技术领域
本发明属于装配式建筑工程技术领域，特别是涉及一种预制断热桥复合保温条板及其制作方法。
背景技术
在建筑墙体中，填充墙是作为填充框架或剪力墙的洞口并承自重的墙体。传统方式是采用砌块砌筑方式，所使用的砌块一般为蒸压加气混凝土层砌块、烧结空心砌块、轻骨料混凝土小型空心砌块等，由工人逐块砌筑施工。
对于装配式建筑来说，通常采用预制条板作为填充墙的基层墙板，所使用的条板一般为蒸压加气混凝土条板、轻集料混凝土条板、玻纤增强水泥条板、硅镁加气水泥条板、粉煤灰泡沫水泥条板、聚苯颗粒水泥夹芯复合条板等，与传统的砌块墙体相比，预制轻质条板减少了现场湿作业，提高了施工效率。
随着建筑工业化要求的不断提升，装配式建筑外墙得到大量的应用，但材质单一的传统轻质条板外墙已经难以适应更高的节能标准，尤其是超低能耗和近零能耗建筑标准，这对墙体系统的保温隔热性能和断热桥性能提出了更高的要求。
为了提升墙体的保温隔热性能，在轻质条板安装后，仍然需要现场粘锚保温板，但由于轻质条板的容重较低，造成材质强度较低，导致保温板锚固的力学性能较差，目前国家标准要求锚栓的抗拉拔力仅为0.3～0.4kN，因此常造成保温板脱落问题。为解决此问题，申请号为202111076181.2的中国专利申请，公开了一种复合保温条板，该复合保温条板由加气混凝土层、保温板、钢丝网片和塑质锚钉组成，但是，该复合保温条板的制作仍采用后浇筑加气混凝土方式，因此不利于干法作业。
发明内容
针对现有技术存在的问题，本发明提供一种预制断热桥复合保温条板及其制作方法，该复合保温条板具有优异的断热桥性能和低传热性能，可采用干法施工，有效避免湿作业带来的污染，减少了施工现场粘锚保温板的环节，将保温板从传统的膨胀锚固方式转变为对拉螺栓的锚固方式，大大提高了保温板的锚固强度；由多块预制断热桥复合保温条板即可拼装成为一面填充墙体，大幅提升了现场施工效率；本发明的预制断热桥复合保温条板不但适用于新建建筑的填充墙，而且适用于既有建筑幕墙系统的节能改造。
为了实现上述目的，本发明采用如下技术方案：一种预制断热桥复合保温条板，包括保温板材、轻质条板、胶粘剂、断热桥螺栓及螺母；在所述轻质条板的室外侧表面设有胶粘剂，所述保温板材通过胶粘剂固定粘接在轻质条板的室外侧表面，在保温板材、胶粘剂及轻质条板上设有贯穿孔，所述断热桥螺栓的螺杆穿装在贯穿孔内，断热桥螺栓的锚盘与保温板材的室外侧表面紧密接触，断热桥螺栓的螺杆端部所对应的贯穿孔在轻质条板上设为扩径孔；所述螺母位于扩径孔内且与断热桥螺栓的螺杆端部螺接紧固配合；在所述扩径孔内充填有填孔砂浆。
