                  摘要
                  新發布的《混凝土結構設計規范》(GB 50010-2002,以下簡稱混凝土規范)中,對鋼筋混凝土結構伸縮縫最大間距的要求比原規范嚴格了,規范用詞由“可”改為“宜”。這就要求在結構設計中,設計者必須認真對待由于超長給結構帶來的不利影響,當增大結構伸縮縫間距或者是不設置伸縮縫時,必須采取切實可行的措施,防止結構開裂。在適當增大伸縮縫最大間距的各項措施中,在結構施工階段采取防裂措施是國內外通用的減小混凝土收縮不利影響的有效方法,我國常用的做法是設置施工后澆帶。另外,當建筑物存在較大的高差,但是結構設計根據具體情況可不設置永久變形縫時,例如高層建筑主體和多層(或低層)裙房之間,也常常采用施工后澆帶來解決施工階段的差異沉降問題。這兩種施工后澆帶,前者可稱之為收縮后澆帶,后者稱為沉降后澆帶,本文就施工后澆帶的設計與施工,結合工程的實踐談談筆者的看法。

                  Abstract   
                  New releases in the "design of concrete structures" (GB 50010-2002. hereinafter referred concrete norms), the reinforced concrete structure of the largest joint spacing requirements than the strict norms, standardized wording from "may" to "desirable." This requires structural design, the designer must take it seriously as long structure to the adverse impact When the distance increases or structural joints is not set up joints, they must take practical Measures to prevent structural cracking. Increases in the appropriate spacing of the largest joint measures, Construction of the anti-crack stage to take measures at home and abroad is a common concrete shrinkage reducing the adverse effects of the effective methods My normal practice is the provision of construction after casting. In addition, when there is a big building height difference, but the structural design in accordance with the specific circumstances may function as a permanent, For example, high-level and multi-storey main building (or lower) between skirt, Construction is often used after pouring bring resolve differences in the construction phase of the settlement problem. Construction of the two after pouring belt, the former may be called contraction casting, which called the settlement belt, Construction on the paper after casting the design and construction of engineering practice talk about my views.
