为了提供适用于农村建房的楼面构件,我院与江苏省扬州建筑材料构件三厂协作,研制了水泥粉煤灰混凝土空心块拼合楼面,于1984年4月通过了技术鉴定。该拼合楼面构件已在小批量生产,经两幢房屋试用,获得用户好评。随着农村普遍建造二层楼房,这种楼面构件将逐步推广应用。一、拼合楼面结构简介该楼面由预应力混凝土倒T形梁与水泥粉煤灰混凝土拼合块拼合而成。倒T形梁与拼合块之间灌筑200号细石混凝土。面层做法与预应力多孔板相同。其结构示意见图1。
In order to provide floor components suitable for building houses in rural areas, our institute cooperated with Yangzhou Construction Material Factory No. 3 of Jiangsu Province to develop a cement fly ash concrete hollow block assembly floor and passed the technical appraisal in April 1984. The flat floor components have been produced in small batches and have been tried out by two houses, gaining praise from users. With the general construction of two-story buildings in rural areas, such floor components will be gradually applied. First, the introduction of the floor structure Introduction The floor is composed of prestressed concrete inverted T-shaped beams and cement fly ash concrete blocks. Between the inverted T-shaped beam and the split block, 200 fine stone concrete is poured. The surface layer is the same as the prestressed porous plate. Its structure is shown in Figure 1.
