Description

Construction dust screen

Technical Field

The application relates to the field of building construction, in particular to a building construction dust screen.

Background

In the time of construction, there is dust to raise in the construction site and fly, in order to reduce the influence of dust to construction site surrounding environment, people can enclose around construction site and establish the dust screen usually.

The dust screen includes support and screen cloth, and the support is used for enclosing to establish outside treating the building of being under construction, is provided with a plurality of locking bolt on the support, and the screen cloth passes through locking bolt can dismantle the connection in the support one side that is close to the building. Usually before the construction, at first at the construction site periphery establish the support, then expand the screen cloth, fix the screen cloth relatively on the support is close to one side of building with locking bolt, dust can reduce the possibility that dust spreads around to the construction site during the construction this moment.

To the correlation technique among the above-mentioned, when wind blows, because the area of contact of locking bolt and screen cloth is less, the effort that consequently screen cloth received around locking bolt is big, and near the screen cloth of locking bolt damages easily this moment, finally leads to the screen cloth can drop from the support, and the steadiness of dust screen is lower.

SUMMERY OF THE UTILITY MODEL

In order to improve the steadiness of dust screen, this application provides a construction dust screen.

The application provides a construction dust screen adopts following technical scheme:

a building construction dust screen comprises a plurality of screen plates, wherein each screen plate comprises an outer frame and screen cloth, and the screen cloth is connected to one side of the outer frame; an inner rod is arranged on the outer frame and is abutted against one side of the mesh cloth, which is far away from the outer frame.

By adopting the technical scheme, when building construction is carried out, a plurality of screen plates are required to be installed outside a building at first, and at the moment, the plurality of screen plates are spliced with one another and surround the building; if windy blows, the screen cloth can shake along with wind, because the screen cloth clamp has increased the fixed area of screen cloth and outrigger between outrigger and interior pole this moment, and the screen cloth receives the average effort of wind with the junction of outrigger and can reduce this moment, and then makes the screen cloth be difficult to damage, reduces the possibility that the screen cloth drops from the outrigger, has reached the purpose that improves the dust screen steadiness.
