Construction joint refers to the concrete pouring process, design or construction needs due to pouring the earlier section, after the pouring of concrete joints formed between. Construction joint is not a real problem of "joint", it is only after the pouring of concrete for more than the initial setting time, and the first one between the pouring of concrete joint surface, called the combination of the surface of the construction joint.
Concrete pouring for the formation of the joint surface successively prone to various hazards and quality problems, therefore, different structural works on the construction joint of the address have to be doubly cautious.
1, what is a construction joint?
Construction Joints: construction organization needs for construction of units in each district located between the left seam. Construction joint is not a real problem of "joint", it is only after the pouring of concrete for more than the initial setting time, and the first one between the pouring of concrete joint surface, called the

施工縫指的是在混凝土澆筑過程中，因設(shè)計要求或施工需要分段澆筑而在先、后澆筑的混凝土之間所形成的接縫。 施工縫并不是一種真實存在的“縫”，它只是因后澆筑混凝土超過初凝時間，而與先澆筑的混凝土之間存在一個結(jié)合面，該結(jié)合面就稱之為施工縫。
　　因混凝土先后澆注形成的結(jié)合面容易出現(xiàn)各種隱患及質(zhì)量問題，因此，不同的結(jié)構(gòu)工程對施工縫的處理都需要慎之又慎。
1、什么叫施工縫？
　　施工縫：因施工組織需要而在各施工單元分區(qū)間留設(shè)的縫。施工縫并不是一種真實存在的“縫”，它只是因后澆注混凝土超過初凝時間，而與先澆注的混凝土之間存在一個結(jié)合面，該結(jié)合面就稱之為施工縫。
