How to use Luoyang construction fencing and how to safely construct construction fencing

1. Construction Measurement

During construction, the ground height difference of the enclosure line should be measured first, and the elevation of the enclosure foundation should be divided into sections according to the height difference. For leveling, unconditioned areas should also be kept as long as possible, and steps should be used to adjust the height difference caused by the ground. The verticality and straightness of the columns should be ensured. Use a theodolite to draw out the baseline according to the diagram in advance, and mark the center point of the columns with a ruler. During construction, first construct every fourth column or several control columns according to the situation, and check their elevation and line. position, and then hang the line to construct the middle column. It is necessary to wait until the strength of the foundation concrete reaches more than 70% before starting to hang the load-bearing baffle.

2. Enclosure form

The construction enclosure is made of blue lightweight sandwich color steel plates. The thickness of the color steel is 0.3mm, the height is 2 meters, and the top and bottom of the enclosure are set at 10cm each. The high steel channel top and steel channel support are equipped with steel columns anchored to the ground every 2.9 meters. The base of the column is a C25 concrete foundation of 50cm×50cm×50cm. The four corners of the steel column bottom plate are connected and fixed with the concrete foundation using expansion bolts. , which can not only reduce the area occupied, but also ensure that the fence is stable, neat and beautiful (see the fence installation diagram for details).

3. Fence decoration

Advertising cloth is used as a decorative material on the fence wall, and the advertising cloth reflects corporate culture or production safety slogans. The fence slogans mainly include: project name, names of participating units, complaint telephone announcements, safe and civilized construction terms, corporate culture terms, etc. The advertising posters are blue with white characters.

In addition to unified promotional text, no other advertisements (except public service advertisements), random pulling of wires, random hanging of objects, or graffiti are allowed on the retaining walls.
