复合材料组合板架,是以加气粉煤灰块和钢筋混凝土格栅体系的肋板为上弦,以角钢和钢管为腹杆及下弦,通过节点板和二次浇混凝土连接而成的一种新型结构。它除具有空间网架的一般特点外尚有下列特点:以复合板代替网架钢上弦,板架合一共同工作,比钢网架节省钢材,利用加气粉煤灰块作填充料不仅减轻了自重(比一般板架重量轻),同时具有良好的保温隔热性能。利用火力发电厂的废料粉煤灰,可变废为利,同时能对清除环境污染起一定作用。结合工程需要,我们设计应用了以此种复合板架为主的三项工程。本文对该设计和计算进行了扼要的介绍。同时对此种结构,进行了模型试验,结果表明,此种板架受力性能良好,整体性和刚度好,安全储备大,实测数据与理论计算值基本一致。说明此种新结构可适用于一般中、小型工业与民用建筑的屋面和楼面工程。
The composite material composite plate frame is a kind of ribs made of aerated fly ash blocks and reinforced concrete grid systems. The angles are steel and steel pipes are the web members and the lower strings. The connection between the gusset plate and the secondary pouring concrete New structure. In addition to the general features of the space grid, it still has the following features: the steel plate is replaced by a composite plate to replace the grid steel, and the plate frames work together to save steel materials compared to the steel grid frame. The use of aerated fly ash blocks as filler material not only reduces The self-weight (lighter weight than the general plate), while having good thermal insulation properties. Using waste fly ash from thermal power plants, variable waste is beneficial, and it can also play a role in removing environmental pollution. In combination with the needs of the project, we designed and applied three projects based on this kind of composite plate frame. This article gives a brief introduction to the design and calculation. At the same time, a model test was carried out on this kind of structure. The results show that this kind of plate frame has good stress performance, good integrity and rigidity, large safety reserves, and the actual measured data are basically consistent with the theoretically calculated values. It shows that this new structure can be applied to the roofing and floor projects of general and small-scale industrial and civil buildings.
