(57) Abstract Objective In the steel-frame component in construction ones of cage rotsukuuThe fire-resistant cladding material which consists of the blend of ru and the cement mortarIn the automatic blowing device which it blows applies, when starup blowingThe fire-resistant cladding material and blowing which you throw away in when ending and are blownScattering the dust which is generated in job process is prevented when alsoBy attaching with the device which is recovered, work environmentThe blowing equipment which can lose the loss of integrity and the fire-resistant cladding materialOffer the position. Constitution To self-propelled platform car 2, it is injected from blowing nozzle 4,It is the box booth which captures the scattering dust of the fire-resistant cladding material 10And others to install the dust scattering prevention device which becomes, on cartridge head of booth 10To provide the accumulating pit 11 of the scattering dust, on the other hand, aforementioned each blowingSending hose 20 of the rock fiber which is jointed to ke nozzle 4It provides bidirectional change-over valve 21, blowing port 21a on the one handTo nozzle 4, other port 21b made the recovery device communicateIt features that it constitutes.
