摘   要： 增加结构保温一体化墙体免拆模板的保温层厚度可实现更高的节能目标 ，然而增加保温层厚度，现有连接件不能很好满足锚固要求 。本文提出适用于较厚保温层免拆模板的连接件，对其连接性能进行分析，以实际工程为研究案例 ，通过ANSYS 将增厚墙体中的连接件替换成改良连接件，对一体化墙体 、加厚免拆模板  的整体性和改良连接件自身受力及变形情况进行分析 。经计算结果分析 ，一体化墙体整体锚固与改良前相比效果明显，免拆模板与现浇墙体协调变形 ，改良连接件改进部位符合受力规律 ，穿出免拆模板背面产生的应力集  中不会对模板造成破坏 ，风压增高的情况下锚固效果优于普通连接件 。结构保温一体化墙体加厚免拆模板连接性能较好。

Abstract:Increasing the thickness of the insulation layer of the structural insulation integrated wall removable template can realize higher energy saving targets, however, after increasing the thickness of the insulation layer, the existing connectors can not well meet the anchoring requirements.This paper proposes the connectors applicable to the thicker insulation layer free template, analyzes its connection performance, takes the actual project as a research case, replaces the connectors in the thickened wall with the improved connectors through ANSYS, and analyzes the integrated wall, the integrality of the thickened free template, and the improved connectors' own force and deformation.After calculating the results of the analysis, the integrated wall overall anchorage compared with the improvement of the former effect is obvious, no demolition template and cast-in-place wall coordinated deformation, improved connectors to improve the part in line with the law of force, wear out the back of the demolition-free template stress concentration will not cause damage to the template,   the wind pressure increases in the case of the anchoring effect is better than the ordinary connectors.The connection performance of the structural thermal insulation integrated wall thickening and non-removal formwork is better.

Keywords：structural insulation integration ; connection performance ; wind load ; stress concentration
