That receives is neat and tidy.In the present embodiment, further included after the step of forming the second gypsum putty layer：It is greasy in the second gypsum
It is polished and is cleaned up with 400# sand paper after sublayer drying.When with sand paper the second gypsum putty layer of polishing, leakage mill is careful not to
It is or putty is worn out.In the present embodiment, the thickness of the second gypsum putty layer is no more than 2mm.
Step S150, the brushing paint layer 15 on gypsum putty layer 14 complete the construction of steel column decorative structure 1.According to not
Same decoration demand, in the external coating dope layer 15 of gypsum putty layer 14.For example, dope layer 15 can be the breast of different colours
Shellac varnish.In the present embodiment, dope layer 15 is fireproof emulsion paint, can increase the fire protecting performance of steel column 2, when improving fire endurance
Between.
In the present embodiment, the brushing gypsum putty on the second scrim layer 13, formed gypsum putty layer 14 the step of it
Before further include：Square staff is set at the column angle of steel column 2.Square staff is added, the protection to steel column decorative structure 1 can be strengthened.
The construction method of above-mentioned steel column decorative structure 1 forms the first boundary by way of using and brushing on the surface of steel column 2
Face oxidant layer 10, the first scrim layer 11, second contact surface oxidant layer 12, the second scrim layer 13, gypsum putty layer 14 and dope layer 15,
Decoration occupied area can be effectively saved, expands plane real area.Using the construction technology of brushing, filled compared to conventional cladding
For decorations, construction technology is saved, and it is fast and simple.In addition, 11 He of the first scrim layer is set in steel column decorative structure 1
Second scrim layer 13 effectively reduces the cracking degree of fireproof coating layer 20, adds the fire protecting performance of steel column 2, improve
Fire resistance period.In addition, the construction method of above-mentioned steel column decorative structure 1 is simple for process, engineering cost is advantageously reduced.

Method handles 20 rough surface of fireproof coating layer.
After fireproof coating layer 20, which is completed to smooth out, to be handled and cleaned, at the external coating interface of fireproof coating layer 20
Agent forms the first interface agent layer 10.In the present embodiment, the thickness of the first interface agent layer 10 is 3-5mm.
After the brushing of interfacial agents is completed, grid cloth is completely hung on the structure of steel column 2 together, forms the first scrim layer
11, the first scrim layer 11 connects the first interface agent layer 10 and second contact surface oxidant layer 12, good by the first scrim layer 11
Flexibility, can prevent the differential expansion between steel column decorative structure 1 and fireproof coating layer 20.In the present embodiment,
The lap of splice of grid cloth is not less than 100mm in one scrim layer 11.
When constructed the first scrim layer 11 after to steel column 2 carry out second of interfacial agents brushing, formed second contact surface agent
Layer 12.Second contact surface oxidant layer 12 is identical with the first interface agent layer 10, can play the role of closure, realizes to fireproof coating layer
20 closure and protection ensures the fire protecting performance of steel column decorative structure 1.In the present embodiment, the thickness of second contact surface oxidant layer 12
For 3-5mm.
Then, grid cloth second is completely hung in 2 structure of steel column, forms the second scrim layer 13, the second scrim layer 13
Second contact surface oxidant layer 12 and gypsum putty layer 14 are connected, strengthens the closure to original structure, and avoids the risk of cracking.In this implementation
In example, the lap of splice of grid cloth is not less than 100mm in the second scrim layer 13.
Then, batch gypsum putty on the second scrim layer 13, forms gypsum putty layer 14.In the present embodiment, gypsum
Putty layer 14 includes the first gypsum putty layer and the second gypsum putty layer, and the second gypsum putty layer covers the first gypsum putty layer.
Applied in two coats gypsum putty layer 14 can provide basis for subsequent decoration construction.In originally implementing, the first gypsum putty layer
It is no more than 2mm with the thickness of the second gypsum putty layer.
In the present embodiment, square staff is equipped at the column angle of steel column 2.Square staff can form straight flange on the crest line at column angle
The part of rupture or cracking, protection and reinforcement gypsum putty 14 layers of most fragile of layer is resisted, ensures the complete of steel column decorative structure 1
Property.
Finally, the brushing paint layer 15 on gypsum putty layer 14 completes the construction of steel column decorative structure 1.It is filled using brushing
The method of decorations sequentially forms the first interface agent layer 10, the first scrim layer 11, the second boundary on the fireproof coating layer 20 of steel column 2
Face oxidant layer 12, the second scrim layer 13, gypsum putty layer 14 and dope layer 15.Construction cost is reduced, shortens the construction period,
And constructing operation is easy.Meanwhile the fire protecting performance of steel construction is strengthened, space occupancy rate is reduced, effectively increases plane
Usable floor area.In addition, above-mentioned steel column decorative structure 1 reduces the use of construction material, the environment protecting of interior decoration is improved.
