Temporary enclosure practice in urban areas

I, urban temporary enclosure practices recommended for reference:

1, according to the delineation of the urban housing construction project construction site enclosure shall use rigid materials and continuous setup, the urban area of the main section of the enclosure wall height shall not be less than 2.5 meters, the general section of the mobile enclosure wall height shall not be less than 1.8 meters.

2, the installation of mobile enclosure according to the pre-reporting and approval of the construction layout plan, the temporary enclosure for measurement and positioning, after the release of the line, please supervise and the owner to be confirmed, and the drawings do not match the part of the timely adjustment.

3, construction site temporary enclosure using the most materials is color steel plate. Color steel plate can be used to make flat foam sandwich panel enclosure, two sides of color steel plate in the middle of a layer of 5cm thick EPS foam as a fence board village material. Its width is generally 950mm; length with the height of the enclosure, if the height of the enclosure is 2 meters, then the height of the color steel plate is close to 2 meters.

4, construction temporary enclosure using 50mm thick white inside blue lightweight double-layer sandwich color steel plate, height 2.0m, column side length of 800mm, high 2m square steel pipe, steel pipe wall thickness of 1.2mm. enclosure top bottom beams using C-type galvanized pressure slot. Every 3m there is a steel column anchored to the ground, the bottom of the concrete pavement column and 90mm × 180mm × 1.5mm steel plate welding, steel plate using four 13mm φ10 expansion bolts anchored to the base surface, to ensure that the temporary enclosure is stable, neat and beautiful.

5, the top of the temporary enclosure to install solar-powered warning red lights, the same spacing and steel columns, set up reflective film signs on the outside of the enclosure in the adjacent lane. The outside of the enclosure adopts the background pattern specified by the company and is equipped with the publicity slogan approved by the company.

Temporary fence installation instructions:

1, temporary fence installation is usually before the civil construction has been formed to deliver the lower foundation of brick or concrete pouring, you can use mechanical expansion bolts, chemical screw inspection, etc., the column steel liner base plate is fixed in the center of the lower part of the foundation for straight line uniform.

2, such as temporary enclosure of the lower part of the foundation has not been formed, it is recommended that the column steel liner to increase the length of the wall directly embedded in the wall, to be wall maintenance period can be formally constructed; or prefabricated embedded parts laid in the wall plane after the column steel liner will be electrodynamic welding and embedded welded, the two ways are characterized by a more solid than the bolt connection, but the pre-setting of the straight line must pay attention to the level of line and line.

3, column steel liner spacing must be consistent with the design dimensions to ensure that the pre-assembled semi-finished products can be connected.
