一般对于变形缝装置的质量考究，可以从它的极限状态来看。所谓的极限状态是指对应于结构或结构构件达到正常使用或耐久性能的某项规定限值。当变形缝装置出现下列状态之一时，应认为超过了正常使用极限状态。
The quality of the general deformation joint device for fastidious, can from the perspective of the limit state of it. The limit state refers to the corresponding to the structure or structures to normal use or durability of a limit. When there is one of the following state of deformation joint device, should think over the serviceability limit state.
(1)影响正常使用或外观的变形；
(1) of the look of the normal use or deformation;
(2)影响正常使用或耐久性能的局部损坏(包括裂缝)；
(2) affect the normal use or durable performance of local damage (including crack);
(3)影响正常使用的振动；
(3) influence the vibration of the normal use;
(4)影响正常使用的其他特定状态。
(4) affect the normal use of other specific condition.
为了保证工程结构具有规定的可靠度，应对变形缝装置结构设计所依据的条件进行相应的控制。根据变形缝装置结构的安全等级划分相应的控制等级。
In order to guarantee the reliability of engineering structure with prescribed, a response to deformation joint device structure design based on the conditions of the corresponding control.
According to the deformation joint device structure safety hierarchy corresponding control level.
当确保变形缝装置没有问题时，在施工中也要注意相应的施工要求与规范。一般建筑施工要求是达到统一可靠度设计，它是指设计的基本原则和方法就是使设计符合技术先进、经济合理、安全适用，确保质量的要求。
When there is no problem to ensure deformation joint device, also should pay attention to in the construction of the corresponding construction requirements and specifications.
General construction requirements are to achieve unified reliability design, it refers to the basic principle and design method is to make the design in line with the advanced technology, reasonable economy, safety, to ensure the quality requirements.
在施工后期，也呀做好建筑结构的监管质量控制工作：
In the late construction, also to do a good job of supervision quality control structure:
(1)勘察与设计的质量控制；
(1) survey and design quality control;
(2)材料和制品的质量控制；
(2) the quality control of materials and products;
(3)施工的质量控制；
(3) the construction of quality control;
(4)使用和维护的质量控制。
(4) the use and maintenance of quality control.
变形缝装置质量与性能检测工作如何才能做好
核心提示：一般对于变形缝装置的质量考究，可以从它的极限状态来看。所谓的极限状态是指对应于结构或结构构件达到正常使用或耐久性能的某项
