摘   要： 增加結(jié)構(gòu)保溫一體化墻體免拆模板的保溫層厚度可實(shí)現(xiàn)更高的節(jié)能目標(biāo) ，然而增加保溫層厚度，現(xiàn)有連接件不能很好滿足錨固要求 。本文提出適用于較厚保溫層免拆模板的連接件，對(duì)其連接性能進(jìn)行分析，以實(shí)際工程為研究案例 ，通過ANSYS 將增厚墻體中的連接件替換成改良連接件，對(duì)一體化墻體 、加厚免拆模板  的整體性和改良連接件自身受力及變形情況進(jìn)行分析 。經(jīng)計(jì)算結(jié)果分析 ，一體化墻體整體錨固與改良前相比效果明顯，免拆模板與現(xiàn)澆墻體協(xié)調(diào)變形 ，改良連接件改進(jìn)部位符合受力規(guī)律 ，穿出免拆模板背面產(chǎn)生的應(yīng)力集  中不會(huì)對(duì)模板造成破壞 ，風(fēng)壓增高的情況下錨固效果優(yōu)于普通連接件 。結(jié)構(gòu)保溫一體化墻體加厚免拆模板連接性能較好。

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
