我们在长春市永春路商贸城营业大厅的施工中,为了便于残疾人也能直接进入大厅购物,特意在位于门厅的出入口处设计坡道并安上防滑条。可是由于原设计的防滑条间距较大,施工防滑条时已到初冬时节,气温低,操作困难,再按原设计施工已无法保证工程质量。因此,根据现场施工条件我们把防滑条的做法由原设计铁屑混凝土改为14螺纹钢筋,原设计间距300mm改为150mm。 具体做法是:做水磨石地面面层时,应设防滑条的位置先预埋一根宽度等于14螺纹钢筋直径的木条(木条埋入深度12mm左右),待水磨石
In the construction of the business hall of Yongchun Road Trade City in Changchun City, we are able to directly enter the hall to facilitate shopping for disabled people. We specially design ramps and anti-slip strips at the entrance and exit of the entrance hall. However, due to the large spacing of the original design of anti-slip strips, construction of anti-slip strips has reached the early winter season, the temperature is low, operation difficulties, and then according to the original design and construction can not guarantee the quality of the project. Therefore, according to the on-site construction conditions, we changed the design of the anti-slip bar from the original design iron chip concrete to 14-thread steel bar, and the original design spacing was changed from 300mm to 150mm. The specific approach is: When making terrazzo floor surface, the location of the anti-slip strips should be pre-embedded with a wooden strip with a width equal to the diameter of the 14-bar rebar (the depth of the wood strip is about 12mm) until the terrazzo
