技术领域：Technical field:
本发明涉及建筑工程技术领域，具体涉及一种矩形钢管龙骨的预制无热桥保温外墙及其制作方法。The invention relates to the technical field of construction engineering, in particular to a prefabricated thermal bridge-free thermal insulation outer wall with a rectangular steel pipe keel and a manufacturing method thereof.
背景技术：Background technique:
随着城市高速发展，建筑能耗逐年増加，越来越多的装配式建筑及绿色施工方法被提上议程，作为国家可持续发展的重点产业，建筑节能行业是实现国家能源安全的重要途径。装配式被动房是一种以混凝土预制构件作为围护结构，保温隔热效果和气密性良好，室内舒适度高，不采用主动式采暖技术的新型房屋。无论是从房屋的施工周期和建筑质量，还是从建成后建筑的室内舒适度和能耗角度来看，都是十分符合当前我国建筑业发展方向的。With the rapid development of cities, building energy consumption is increasing year by year, and more and more prefabricated buildings and green construction methods have been put on the agenda. As a key industry for national sustainable development, the building energy-saving industry is an important way to achieve national energy security. The prefabricated passive house is a new type of house with prefabricated concrete components as the enclosure structure, good thermal insulation effect and air tightness, high indoor comfort, and does not use active heating technology. Whether it is from the construction period and construction quality of the house, or from the perspective of the indoor comfort and energy consumption of the completed building, it is very in line with the current development direction of my country's construction industry.
墙体在建筑中作为空间主要的分隔构件，而其保温隔热性又直接影响建筑物的采暖制冷能耗，因此墙体的保温效果对建筑整体的保温和节能是至关重要的。目前，我国传统的建筑保温是在建筑物主体建造完成后，在建筑物外立面粘贴外保温层，但这种保温墙体的施工方式具有拼缝多、易脱落、热桥大、整体性差等缺点，因此现有墙板难以满足低能耗、无热桥的设计需要，而且钢筋混凝土墙体刚性过强，在水平力作用下，墙板与墙板之间容易产生错缝，不利于气密性和防水性能的保证，随着我国建筑节能标准的不断提升，尤其是在德国被动房建筑的“无热桥”理念要求下，如何设计一种工厂预制、可多块组合装配、低能耗、无热桥、整体性好的装配式保温外墙成为有待解决技术问题。The wall is the main space separating component in the building, and its thermal insulation directly affects the heating and cooling energy consumption of the building. Therefore, the thermal insulation effect of the wall is crucial to the overall thermal insulation and energy saving of the building. At present, the traditional building insulation in China is to paste the external insulation layer on the facade of the building after the main body of the building is constructed. However, the construction method of this insulation wall has many joints, easy to fall off, large thermal bridges, and poor integrity. Therefore, the existing wall panels are difficult to meet the design requirements of low energy consumption and no thermal bridges, and the reinforced concrete walls are too rigid. The guarantee of tightness and waterproof performance, with the continuous improvement of China's building energy-saving standards, especially under the requirements of the "no thermal bridge" concept of German passive house buildings, how to design a factory prefabricated, multi-block assembly, low energy consumption , no thermal bridge, and good integrity of the prefabricated thermal insulation exterior wall has become a technical problem to be solved.
