一种结构与节能一体化装配式预制外墙板及制备方法Structure and energy-saving integrated prefabricated prefabricated exterior wall panel and preparation method thereof 技术领域Technical field
本发明涉及一种建筑工程领域,具体涉及一种结构与节能一体化装配式预制外墙板及制备方法。The invention relates to the field of building engineering, in particular to a structural and energy-saving integrated prefabricated prefabricated exterior wall panel and a preparation method thereof.
背景技术Background technique
我国正处于工业化、城镇化加速发展的重要阶段,是环境约束与经济社会快速发展的矛盾突出阶段,节能减排形式严峻,传统建筑业存在耗能大、对环境扰动大等问题。因此,2013年以来,我国先后发布了《绿色建筑行动方案》、《关于推进建筑业发展和改革的若干意见》等文件,号召以绿色节能建筑为主旨,以预制装配式建筑为主要生产方式,走新型建筑工业化之路,实现建筑经济积极转型升级。China is in an important stage of accelerating industrialization and urbanization. It is a contradictory stage of environmental constraints and rapid economic and social development. The form of energy conservation and emission reduction is severe, and the traditional construction industry has problems such as high energy consumption and large disturbance to the environment. Therefore, since 2013, China has successively issued the “Green Building Action Plan” and “Several Opinions on Promoting the Development and Reform of the Construction Industry”, calling for green energy-saving buildings and prefabricated buildings as the main production methods. Take the road of industrialization of new buildings and realize the active transformation and upgrading of the construction economy.
建筑墙体是建筑物的重要组成部分,约占建筑总工程量的三分之一,实现建筑墙体由传统人工砌块转变为工业化墙板制造是实现建筑工业化发展的重要举措。其中,建筑外墙是与室外环境接触最多的外围护结构,也是最大的耗能构件,其保温隔热性能对建筑的能耗影响甚大,尤其在采暖能耗中所占的比例最大,约占总能耗的三分之一。此外,大量地震震害表明,传统建筑维护墙体在地震中损坏严重,大量出现变形、破坏、甚至倒塌,危及人身安全。因此,建筑外墙的保温节能性以及结构安全性至关重要。工信部2015年10月发布《促进绿色建材生产和应用行动方案》(工信部联原〔2015〕309号)[]提出:“重点发展本质安全和节能环保、轻质高强的墙体材料……。鼓励发展保温、隔热及防火性能良好、施工便利、使用寿命长的外墙保温材料,开发推广结构与保温装饰一体化外墙板”。Building wall is an important part of the building, accounting for about one-third of the total construction volume of the building. Realizing the transformation of the building wall from traditional artificial block to industrial wallboard is an important measure to realize the industrialization of the building. Among them, the external wall of the building is the outer protection structure with the most contact with the outdoor environment, and it is also the largest energy-consuming component. Its thermal insulation performance has a great influence on the energy consumption of the building, especially in the heating energy consumption. It accounts for one-third of the total energy consumption. In addition, a large number of earthquake damages indicate that the traditional building maintenance wall is seriously damaged during the earthquake, and a large number of deformations, damages, and even collapses endanger the personal safety. Therefore, the insulation and energy conservation of the building's exterior walls and structural safety are of paramount importance. In October 2015, the Ministry of Industry and Information Technology released the Action Plan for Promoting the Production and Application of Green Building Materials (Ministry of Industry and Information Technology, No. 309 [2015]) [] proposed to focus on the development of intrinsically safe and energy-saving, lightweight and high-strength wall materials. Develop external wall insulation materials with good insulation, heat insulation and fireproof performance, convenient construction and long service life, and develop and promote structural and thermal insulation and decorative exterior wall panels.
而现在传统的外墙保温做法有如下四个问题:1、《外墙外保温工程技术规定》JGJ144规定,外墙外保温工程的使用年限不应少于25年,故外墙外保温不能与建筑同寿命,后期围护、更换等问题暂无较好的解决方案。2、保温材料易燃,如09年央视大火,其外层才用是易燃的聚苯板,导致了火势的一发不可收,这次火灾造成直接经济损失上亿元。3、建筑保温二次施工,保温系统与主体结构分开施工,延长施工周期。4、现场仍存在湿作业,工业化程度低。Nowadays, the traditional external wall insulation practice has the following four problems: 1. The technical regulations for external thermal insulation engineering of the external wall JGJ144 stipulates that the service life of the external thermal insulation project should not be less than 25 years, so the external thermal insulation of the external wall cannot be There is no good solution for the problems of building life, late enclosing and replacement. 2, the insulation material is flammable, such as the CCTV fire in 2009, its outer layer is only flammable polystyrene board, resulting in a fire is not acceptable, this fire caused direct economic losses of hundreds of millions. 3. The second construction of building insulation, the insulation system and the main structure are constructed separately, and the construction period is extended. 4. There are still wet operations on site, and the degree of industrialization is low.
因此本发明提出了一种结构与节能一体化装配式预制外墙板及其生产方法,以绿色节能为宗旨,以解决传统建筑墙体保温体系的技术缺陷为目的,密切契合建筑工业化发展需求,达到保温与建筑同寿命,保温、围护、结构一体,墙体与保温同时工业化生产、施工,有利于建筑节能产业化推广。Therefore, the present invention proposes a structural and energy-saving integrated prefabricated prefabricated exterior wall panel and a production method thereof, aiming at green energy conservation, aiming at solving the technical defects of the traditional building wall insulation system, and closely conforming to the development requirements of the building industrialization. It achieves the same life span of insulation and construction, integrates heat preservation, enclosing and structure, and industrial production and construction of wall and heat preservation at the same time, which is conducive to the promotion of building energy-saving industrialization.
