本发明涉及一种免拆高性能水泥砂浆模板保温再生混凝土T形柱及作法，属于结构工程技术领域。 The invention relates to a high-performance cement mortar formwork thermal insulation recycled concrete T-shaped column and a method thereof, which belong to the technical field of structural engineering.
背景技术 Background technique
我国是能耗大国，建筑能耗又占全国总能耗的很大一部分，单位建筑能耗比同气候条件下发达国家高出二十余倍，建筑能源在高消耗的过程中很容易对环境产生诸多不良影响。我国建筑能耗在总能耗中的比重已从1980年的13％上升到现在的35％左右，大力发展节能型建筑已经成为共识，伴随着对节约能源与保护环境要求的不断提高，建筑围护结构的保温技术也在日益加强，但是行业中现有的保温技术存在许多不足之处，最突出的一点就是保温材料的选择存在困难，保温材料要求密度低、导热系数小、如加气混凝土砌块、聚苯乙烯泡沫塑料板、轻骨料砂浆等。这类材料的特点和人们的要求存在矛盾：保温性能好的材料多是多孔的，阻水性差、强度低。因此找到一种有良好的保温性能且阻水性又好的材料就显得格外重要。 my country is a country with a large energy consumption, and building energy consumption accounts for a large part of the country's total energy consumption. The unit building energy consumption is more than 20 times higher than that of developed countries under the same climate conditions. Building energy is easy to damage the environment in the process of high consumption. produce many adverse effects. The proportion of my country's building energy consumption in the total energy consumption has risen from 13% in 1980 to about 35% now. It has become a consensus to vigorously develop energy-saving buildings. With the continuous improvement of requirements for energy conservation and environmental protection, building enclosures The insulation technology of the protective structure is also being strengthened day by day, but there are many deficiencies in the existing insulation technology in the industry. The most prominent point is the difficulty in the selection of insulation materials. Blocks, polystyrene foam boards, lightweight aggregate mortar, etc. The characteristics of this type of material are in contradiction with people's requirements: materials with good thermal insulation performance are mostly porous, poor water resistance and low strength. Therefore, it is very important to find a material with good thermal insulation performance and good water resistance.
近二、三十年，我国大规模的现代化建设，带来了建筑业的蓬勃发展，每天都有旧建筑物被拆除，新建筑物在兴建。这样，产生大量的建筑垃圾。我国建筑垃圾的数量已占到城市垃圾总量的35％左右，经过对砖混结构、全现浇结构和框架结构等建筑的施工材料损耗的粗略统计，在每万平方米建筑的施工过程中，仅建筑废渣就会产生500多吨。由此引发的资源、能源和环境问题也日益严重。因此对建筑废 弃物的再生利用，把城市建筑垃圾减量化和资源化处理是以后建筑行业的大趋势。 In the past 20 to 30 years, my country's large-scale modernization has brought about a vigorous development of the construction industry. Every day, old buildings are being demolished and new buildings are being built. Like this, produce a large amount of construction wastes. The amount of construction waste in my country has accounted for about 35% of the total amount of urban waste. After rough statistics on the loss of construction materials for buildings such as brick-concrete structures, full cast-in-place structures and frame structures, in the construction process of every 10,000 square meters of buildings , only construction waste will produce more than 500 tons. The resulting resource, energy and environmental problems are becoming more and more serious. Therefore, the recycling of construction waste and the reduction and recycling of urban construction waste will be the general trend of the construction industry in the future.
传统的钢筋混凝土柱保温性能较差，保温性能有待提高，且要用到大量的传统建筑原材料，然而传统的建筑原材料不是永远用不完的。基于此，本发明提出了一种简单，易于施工，用永久性免拆高性能水泥砂浆板代替传统模板，现浇掺和有一定量玻化微珠的再生混凝土组合承重柱，相比于传统的混凝土承重柱，其保温性能和承载力显著提高，再生混凝土的应用将城市建筑垃圾向减量化和资源化方向处理，再生骨料孔隙率大有消音和保温的优点。同时砂浆模板免拆，提高了结构的整体性和抗震性能，非常适用于低多层建筑的结构新体系。 The thermal insulation performance of traditional reinforced concrete columns is poor, and the thermal insulation performance needs to be improved, and a large amount of traditional building materials are used. However, traditional building materials are not inexhaustible. Based on this, the present invention proposes a simple and easy-to-construct recycled concrete composite load-bearing column that replaces the traditional template with a permanent non-demolition-free high-performance cement mortar board and mixes a certain amount of vitrified microbeads. Compared with the traditional Concrete load-bearing columns have significantly improved thermal insulation performance and bearing capacity. The application of recycled concrete can reduce and recycle urban construction waste. The porosity of recycled aggregates has the advantages of sound attenuation and thermal insulation. At the same time, the mortar formwork does not need to be disassembled, which improves the integrity and seismic performance of the structure, and is very suitable for the new structural system of low-rise buildings.
