 房屋鉴定非常重要,当房屋出现地基下沉现象应及时委托专业的房屋结构安全检测鉴定部门对房屋的安全性进行房屋鉴定,为后续的安全使用及修复提供科学可靠的依据,为您分享如何判断地基是否下沉:

1、墙面、地板出现裂缝现象

地基沉降的主要信号是房屋及其墙面出现裂缝,地基下沉造成的裂缝通常呈对角线,比如:墙壁裂缝突然出现在房屋内部的石灰泥墙面或房屋外部的砌砖上,地基下沉产生的裂缝通常比发丝裂缝还要宽,这是由于结构的自然运动造成的,且裂缝的顶端通常较宽。

2、桩基和烟囱处裂缝

除墙面裂缝和地板裂缝外,裂缝也有可能出现在柱基和烟囱处。由于房屋沉降,烟囱有可能发生倾斜。

3、道路凹凸不平

房屋附近的道路沉降和街道路面沉降通常可看到地面坑洼,凹陷和凹凸不平。

4、门窗卡住

地基沉降的发生迹象在房屋的薄弱点,例如:门窗。由于房屋已经发生位移,即可发现门窗卡住现象,卡住的原因是因为地基发生沉降,通常是在房屋接缝处,地板和主结构的延伸处出现地基沉降现象,因此门窗卡住可能就意味着延伸在移动或者已经脱离了主结构。

Housing appraisal is very important. When the foundation sinks in the house, it is necessary to entrust the specialized housing structure safety inspection and appraisal department to carry out housing appraisal in a timely manner, so as to provide a scientific and reliable basis for the subsequent safe use and restoration. Share how to determine whether the foundation is sinking:
1, cracks in the wall, floor phenomenon
The main signal of foundation settlement is the cracks in the house and its walls. The cracks caused by the sinking of the foundation are usually diagonal. For example, wall cracks suddenly appear on the limestone walls inside the house or the masonry outside the house. The cracks generated by the sinking of the foundation are usually wider than the hairline cracks, which are caused by the natural movement of the structure, and the top of the crack is usually wider.
2, cracks in pile foundation and chimney
In addition to wall cracks and floor cracks, cracks may also appear in the base and chimney. Due to the settlement of the house, the chimney may tilt.
3, road uneven
Road subsidence and street road subsidence in the vicinity of houses are usually seen as potholes, depressions and uneven surfaces.
4, doors and Windows stuck
Signs of foundation subsidence occur at weak points in the house, such as doors and Windows. Because the house has been displaced, it can be found that the doors and windows are stuck. The reason for the jam is that the foundation has settled, usually at the seams of the house, and the ground and the extension of the main structure have ground settlement. Therefore, the jammed doors and Windows may mean that they are moving or have been detached from the main structure.
