蚌埠市建筑安装工业公司大搞墙体改革,利用预制厂的生产条件,自己动手生产混凝土空心砌块,在蚌埠市已推广了近万平米的空心砌块建筑(右图示用顶升式成型机生产空心砌块)为了提高砌块建筑的抗震性能,采取了下列措施:①基础顶设置现浇钢筋混凝土圈梁一道,最下面一皮砌块所有孔洞内填100号素混凝土与地基梁紧密锚固以加强房屋整体刚度。②在纵横墙接头转角等处的砌块圆孔内,从基础至屋面加配2φ12钢筋并用150号混凝土灌实。③每层设置200号钢筋混凝土圈梁一道。④砌块与砖墙交接处均应在砌块水平缝内设置钢筋网片连接。⑤搁置大梁的砌块,孔洞内配筋加固并用200号混凝土填实。
Handan City Construction & Installation Industrial Co., Ltd. has been engaged in wall reforms, and has used its production conditions to produce concrete hollow blocks by itself. In Handan, it has promoted nearly 10,000 square meters of hollow block building (the right figure shows jacking molding. Machine-producing Hollow Blocks In order to improve the seismic performance of block buildings, the following measures have been taken: 1 In-situ reinforced concrete ring beams are installed at the base of the foundation, and all the holes in the lowest surface block are filled with 100-element plain concrete and foundation beams. Anchor to strengthen the overall stiffness of the house. 2 Add 2φ12 steel reinforcements from the foundation to the roof and fill them with No. 150 concrete in the round holes of the blocks at the corners of the vertical and horizontal wall joints. 3 Set 200# reinforced concrete ring beams in each floor. 4 The connection between the block and the brick wall shall be provided with a reinforced mesh connection within the horizontal seam of the block. 5 Shelf of shelving beams shall be placed. The holes shall be reinforced and reinforced with No. 200 concrete.
