在西安市草阳小区6万m~2住宅建设的试点工程中已形成经过改造的砖混建筑、竖向配筋空心砖建筑和内浇外砌大模建筑三个体系。具体做法:(1)发展成套建筑体系。三个体系设计基本做到:参数是优选的,构配件是通用定型的,构造节点做法是统一的,设计的组合是多样的;(2)进行墙体改革。目前西安地区主要推广应用定型的26圆孔KP_1承重空心砖,效果较好;(3)提高工业化水平。草阳小区砖混和空心砖体系的预制化程度已由40%提高到60%;(4)进行施工工艺改革;采用钢模生产清水构配件,减少湿作业;推行硬架支模新工艺:施工程序趋向合理,缩短工期:改进卫生设备,抓施工机具配套;(5)加强组织领导。
In the pilot project of the residential construction of 60,000 m2 in Caoyang Community of Xi’an City, three systems, namely the reformed brick-concrete building, vertical reinforced hollow brick building, and in-situ external brick building, have been formed. Specific approach: (1) Develop a complete set of building systems. The three system designs basically do the following: the parameters are preferred, the component parts are universally fixed, the construction node practices are uniform, the design combinations are diverse; and (2) the wall reform is performed. At present, Xi’an area mainly promotes the use of 26-hole KP_1 load-bearing hollow bricks with good shape, and the effect is better. (3) Increase the level of industrialization. The prefabrication degree of the brick-mixed hollow brick system in Caoyang District has been increased from 40% to 60%; (4) The construction process reform; the use of steel molds to produce clean water components to reduce wet work; and the implementation of a new hard-frame mold process: construction The procedures tend to be reasonable and the construction period is shortened: the improvement of sanitary equipment, and the construction of supporting equipment; (5) Strengthening the organization and leadership.
