About the caulking material of fireproof board construction. The caulking material used in the product should have certain flexibility and expansion performance to prevent the sheet from being pulled. This kind of caulking material is not allowed to prepare, and the cost is not high, so it is supplied or formulated by the plate manufacturer. The nails used to fix the plate must be derusted or stainless steel nails should be used. Some overseas countries directly stipulate that the nails used in the construction of GFRP must be stainless steel nails. Because there are chlorine salts in the glass magnesium fire-retardant board, the corrosion of chlorine salt to iron is well known in the world. After more than one year, rust spots appear on the surface of embedded nail heads in many projects using fire-retardant boards in China, and after a period of time, the rust spots will swell into a lump. However, the wetter the quality environment is, the earlier the problem will be exposed. To avoid the occurrence of this problem, it is necessary to ensure that the nails are not corroded.
               

　　質(zhì)量通?。褐鼾埞?、次龍骨縱橫方向線條不平直。原因分析：主龍骨、次龍骨受扭折，雖經(jīng)修整，仍不平直。掛鉛線或鍍鋅鐵絲的射燈位置不正確，拉牽力不均勻。未拉通線全面調(diào)整主龍骨、次龍骨的高低位置。測(cè)吊頂?shù)乃骄€有誤差，中間平面起拱度不符合規(guī)定。

　　Common quality problems: the vertical and horizontal lines of main keel and secondary keel are not straight. Cause analysis: the main keel and the secondary keel are twisted and broken, but they are still uneven and straight after trimming. The position of spotlight with lead wire or galvanized iron wire is not correct and the pulling force is uneven. The height position of main keel and secondary keel shall be fully adjusted without drawing through line. There is an error in the horizontal line of the ceiling, and the camber of the middle plane does not meet the requirements.

　　預(yù)防措施：凡是受扭折的主龍骨、次龍骨一律不宜采用。掛鉛線的釘位，應(yīng)按龍骨的走向每間1.2m射一支鋼釘。拉通線，逐條調(diào)整龍骨的高低位置和線條平直。四周墻面的水平線應(yīng)測(cè)量正確，中間按平面起拱度1/200～1/300。

　　Preventive measures: all twisted main keel and secondary keel should not be used. For the nail position with lead wire, one steel nail shall be shot at 1.2m per room according to the direction of keel. Pull through the line, adjust the height of the keel one by one and make the line straight. The horizontal line of the surrounding wall should be measured correctly, and the camber in the middle should be 1 / 200 ~ 1 / 300.

　　吊頂造型不對(duì)稱，罩面板布局不合理：原因分析未在房間四周拉十字線。未按設(shè)計(jì)要求布置主龍骨、次龍骨。鋪安罩面板流向不正確。預(yù)防措施：按吊頂設(shè)計(jì)標(biāo)高，在房間四周的水平線位置拉十字線。按設(shè)計(jì)要求布設(shè)主龍骨、次龍骨。中間部分先鋪整塊罩面板，余量應(yīng)平均分配在四周較外邊一塊。

　　The shape of the ceiling is asymmetric, and the layout of the cover panel is unreasonable: the cross center line is not drawn around the room. The main keel and secondary keel are not arranged according to the design requirements. The flow direction of the cover plate is not correct. Preventive measures: according to the design elevation of the ceiling, draw the cross center line at the horizontal line around the room. The main keel and secondary keel shall be arranged according to the design requirements. The middle part shall be paved with a whole cover plate first, and the surplus shall be evenly distributed around the outside.
