前言在农村房屋建设中,混凝土屋盖已为较多的建房户所采用,但由构件笨重给目前尚缺乏施工机械的农房建设带来一定的困难。为了使混凝土构件轻型化,我所与太原市北郊区工程队合作,在改进混凝土屋盖型式方面进行了尝试,对一种新型组合拱板屋盖进行了试验研究。这种组合拱板造价低,重量轻,轻便灵活,便于入力搬运和施工操作。(见表1,2) Foreword In the construction of rural houses, the concrete roof has been adopted by a large number of building houses, but it is difficult for the construction of rural houses that currently lacks construction machinery due to heavy components. In order to make the concrete components lightweight, we cooperated with the northern suburban engineering team of Taiyuan City and tried to improve the type of concrete roofs. A new type of composite arch roof was experimentally studied. This kind of combined arch plate has the advantages of low cost, light weight, light and flexible, and easy handling and construction operations. (See Table 1, 2)
