反面、コストが高くなる問題があった。2. Description of the Related Art Conventionally, as a fireproof coating of a steel frame material, there are a method of spraying wet rock wool mortar, a method of attaching a calcium silicate molding plate, and a method of mixing rock wool and cement slurry and spraying the mixture. In the method of spraying rock wool mortar or the method of spraying a mixture of rock wool and cement slurry, there is a problem that dust is easily scattered and the work place becomes dirty, and when a molded plate is used, installation work is troublesome. ing. There is also a method of coating a steel frame with a formed plate obtained by appropriately cutting a blanket made of rock wool in a band shape.However, since the fire resistance of the rock wool formed plate alone is poor, the surface must be covered to cover it. It is necessary to use a protective material, and the workability is good, but there is a problem that the cost is high.

被覆が得られるようになる。According to the present invention, since the cement slurry impregnated in the formed rock wool plate is solidified, the fire resistance is improved as compared with the case where only rock wool is used. Also, when coating around the steel frame material, firstly the rock wool molded plate is temporarily fixed by a post-fixing pin, and the cement slurry is spread in the rock wool molded plate by impregnating with the cement slurry, and this is solidified. Coating with a rock wool molded plate with improved fire resistance can be obtained.

が得られる。Next, the present invention will be described in detail with reference to an embodiment shown in FIG. The illustrated example shows a case where the steel beam 1 is covered. First, a plurality of weld pins 2 are implanted in the steel beam 1 by welding. The rock wool forming plate 3 is wound around the steel beam 1 while the weld pin 2 is pierced, and the rock wool forming plate 3
The rock wool molding plate 3 is temporarily fixed by bending the weld pin 2 while using the washer 4 on the outer surface side of the plate. Rock wool molded plate 3 temporarily fixed in this way
, A cement slurry fed by a suitable pumping means is applied to an injector 6 which is made to blow out from a plurality of injection needles 5, and the injection needle 5 is inserted into the rock wool molding plate 3 to inject the cement slurry. And impregnated. Thereafter, the impregnated cement slurry is allowed to solidify naturally. Thus, a coating composed of the rock wool molded plate 3 in which the impregnated cement slurry has solidified is obtained around the steel beam.

のである。As described above, according to the structure of the present invention, since the periphery of the steel frame is covered with the rock wool formed plate obtained by impregnating and solidifying the cement slurry, only the rock wool formed plate is covered. As a result, a refractory structure having much better fire resistance can be obtained. Further, since a rock wool forming plate is attached to the steel frame material through a plurality of retrofitting pins implanted in the steel frame material, the rock wool forming plate is impregnated with cement slurry and solidified.
Dust scattering does not occur as in the case of spraying conventional rock wool mortar or rock wool cement slurry.Since the construction work is simple, it is easy to form a refractory coating, and a surface protective material or cement powder It is possible to use a low-cost coating material without the need to mix in any of them, and to achieve an effect that is extremely excellent in practicality.
