Description

TECHNICAL FIELD

[0001] The application relates to the technical field of foundation fences, in particular to a foundation fence for building construction. BACKGROUND

[0002] During the building construction process, various foundation pits are dug. In order to isolate the foundation pit from the surrounding construction area during the construction period, a foundation fence is installed along the periphery of the foundation pit. The foundation fence can achieve the warning function, so that the construction personnel can bypass the foundation fence and avoid the phenomenon of personnel entering the foundation pit by mistake. The existing public technical number CN221957333U proposes a foundation fence. According to the shape of the foundation pit edge, the folding plate is bent, so that the fence body is adapted to the shape of the foundation pit edge. Then, the sleeve is rotated out of the storage groove. By rotating the sleeve ring, the screw rod is extended, and then the screw rod and the sleeve are adjusted to the appropriate length. Then, the fixing nail is used to fix the fixing block through the connecting hole, so that the fixing and adjustment of the fence body are completed. The device not only guarantees the protection effect, but also can adapt to the shape of the edge of different foundation pits, thereby improving the adaptability range. However, the foundation fence in the above-mentioned related technology still has the following defects: the foundation fence in the comparative document needs to be carried and installed, which requires a large amount of labor to carry out the carrying work. After installation, the height of the fence cannot be adjusted as needed. The foundation fence is directly placed on the periphery of the foundation pit, and the stability is not enough. After accidental falling and impact, the personnel can easily slip, which can cause the personnel to fall into the foundation pit. Therefore, the application provides a foundation fence for building construction. CONTENT OF THE UTILITY MODEL
