At present, the common dust-raising shelter for construction sites mainly comprises two types, namely a fixed structure, a shed body which is usually covered by a steel frame supporting framework and dustproof mesh cloth and needs to be fixed on the ground through bolt anchoring or welding, the stable shielding can be provided, the whole dust-raising shelter cannot be moved, the dust-raising shelter can be disassembled completely and then reassembled during site replacement, and a movable structure, such as a shed body with a pulley, a block-type dustproof plate and a foldable support arranged at the bottom, wherein the shed body can realize displacement through push-pull or sectional conveying.
The defects of the prior art are:
The fixed dust shielding shed is immovable due to the structure, and the shed must be thoroughly detached and re-erected during field replacement, so that construction interruption time is long, component loss is easily caused by repeated disassembly and assembly, and material and labor cost are remarkably increased. The problem is improved to a certain extent by the partially movable or modularized shielding shed, but the shielding shed still depends on multi-component splicing and manual carrying, and particularly for a large shielding shed, the shielding shed needs a plurality of persons to cooperatively operate, the labor cost is relatively high, and the requirements of construction operation on cost reduction and synergy are difficult to meet.
