凡目睹小砌块建筑楼施工的观众都会有这么一个共同的感觉,即工人的砌筑速度比普通砖混快,但一到浇灌钢筋混凝土圈梁时,速度就马上慢了下来,普通砖混结构很快追赶上来,于是小砌块对于砌筑速度的优越性就显不出来.省内外一些建筑设计及施工单位都曾试图以预制槽形圈梁块(以下简称圈梁块)代圈梁模板浇灌钢筋混凝土圈梁,以达到节约模板,提高施工效率的目的.但由于圈梁块的型号规格繁多而又不统一,给生产安排造成困难,同时由于使用圈梁块后,建筑立面不易处理,给推广应用增加了不少阻力.有些工地甚至还出现过一层 The viewers who have witnessed the construction of the small block building will have such a common feeling that the masonry speed of the workers is faster than that of ordinary bricks, but once the reinforced concrete ring beam is poured, the speed will be slowed down immediately. The structure quickly catches up, so the superiority of the small blocks to the masonry speed is invisible. Some building design and construction units inside and outside the province have tried to ring beam with pre-groove ring beams (hereinafter referred to as ring beams). The formwork is watered with reinforced concrete ring beams to achieve the purpose of saving the formwork and improving the construction efficiency. However, due to the numerous and unconformable model specifications of the ring beams, it is difficult to arrange the production. At the same time, the building facade is not easy to use due to the use of ring beams. Processing, to increase the application of a lot of resistance. Some sites even appeared in a layer
