  • 房屋安全鉴定查勘的顺序
  • 本站编辑:浙江中赫工程检测有限公司发布日期:2020-01-08 19:34 浏览次数:

房屋鉴定也是按这样的顺序,先外部后内部、先上部后底部、先承重构件后非承重构件、先局部后整体、先表面后隐蔽。下面就一起去看看吧。

一、先外部后内部

1、外部:主要了解房屋的结构类型、结构外观损坏的情况、整体变形情况、房屋周边环境情况、地基基础情况等;

2、内部:主要了解房屋各类构件的工作状态及损伤情况。

二、先上部后底层

1、上部:主要了解房屋上部各楼层结构中不利结构的工作状态,检查鞭梢效应对结构的影响,尤其是温度应力及变形影响;

2、底层:底层是承重楼层中最重要的部分,各类作用力相对集中,当底层出现变形、裂缝等情况时,应重点查勘房屋内部结构中的承载构件.

三、先承重构件后非承重构件

1、承重构件:主要了解房屋结构承重构件工作状态及完损情况,判断其是否存在失效状态;

2、非承重结构:主要了解非承重构件的构造、连接、整体性、牢固性、完损等情况。

 四、先局部后整体

1、局部:主要了解房屋局部结构构件的完损状况,判断其是否属于孤立事件,是否对整体产生影响。

2、整体:主要了解房屋整体结构的完损状况,尤其对因房屋整体侧向位移、水平变形产生的构件裂缝进行重点排查,按照传力树概念对结构整体进行分析,及时发现存在的问题,并区别局部与整体之间是否存在着影响关系。

 五、先表面后隐蔽

1、表面:主要通过结构构件的表面完损状况进行查勘,当怀疑其内部存在缺陷时,应进行必要的深入检测。

2、隐蔽:主要通过结构构件的有规律的表面现象,或上部结构带有明显的因下部结构损坏导致的问题特征时,应对存在问题的隐蔽部位进行检查。


Building appraisal is also in this order, first external after the internal, first upper after the bottom, first load-bearing components after non-load-bearing components, first local after the overall, first surface after concealment. Let's take a look at it together. First, the external after the internal 1, External: The main understanding of the structure of the housing type, structural appearance damage, the overall deformation, housing surrounding environment, Foundation Conditions; 2, the internal: The main understanding of the housing components of the working state and damage. 2. First the upper part and then the bottom part 1. The upper part: The main purpose is to understand the working state of the unfavorable structure in the upper part of the building, and to check the influence of whipping effect on the structure, especially the influence of temperature stress and deformation; 2. Ground floor: The ground floor is the most important part of the load-bearing floor, all kinds of forces are relatively concentrated, when the ground floor deformation, cracks, etc. . 3. load-bearing member first and then non-load-bearing member 1. load-bearing member: to know the working state and damage condition of load-bearing member of building structure, and to judge whether there is failure state; 2, non-bearing structure: The main understanding of non-bearing components of the structure, connection, integrity, firmness, damage and so on. Part of the first part of the whole 1, part: The main part of the housing structure to understand the damage status, to determine whether it is an isolated event, whether the impact on the whole. 2. WHOLENESS: The main purpose of this paper is to find out the complete and damaged condition of the integral structure of the building, especially to check out the cracks of the members caused by the lateral displacement and horizontal deformation of the whole building, and to analyze the whole structure according to the concept of force transfer tree, find out the problems in time and distinguish whether there is an influence relationship between the part and the whole. 5. Surface first, then hidden 1. SURFACE: the surface of the structural components through the surface damage survey, when the internal defects are suspected, the necessary in-depth testing should be conducted. 2. CONCEALMENT: Inspection of the concealed part of the structure should be carried out mainly through the regular surface phenomena of the structural members or when the upper part of the structure has obvious characteristics of the problem caused by the damage of the lower part of the structure.
