Specification, price and construction technology of grid ceiling

Aluminum grilleThe main and auxiliary keels are distributed vertically and horizontally, with distinct layers, strong three-dimensional sense, novel shape, fire and temperature resistance, good ventilation, and air-conditioning ports, exhaust ports, drop-grade, lamps and lanterns can be installed in the ceiling, which are widely used in large shopping malls, bars, waiting rooms, airports, subways and other stations, Long as new.
The standard of conventional aluminum grille (see smooth surface from bottom) is 10mm or 15mm, and the height is 40mm, 60mm, 80mm and 90mm.
Aluminum grid grid sizes are 150 X150mm, 200X 200mm 250x 250mm 300x 300mm to choose from.
      片状格栅常规格尺寸为（mm） ：10*10、15*15、25*25、30*30、 40*40、50*50、60*60 Aluminum grille的价格 间距越小 价格越高；Aluminum grille ceiling元/㎡ Aluminum grille吊顶 元/㎡ Aluminum grille ceiling 元/㎡Aluminum grille ceiling黑/白色烤漆 100*100*0.6 ㎜厚*42 ㎜高 58.00 黑/白色烤漆 100*100*0.4 ㎜厚*42 ㎜高 51.00 黑/白色烤漆 100*100*0.6 ㎜厚*35 ㎜高 52.00 黑/白色烤漆 100*100*0.4 ㎜厚*35 ㎜高 45.00 元/㎡Aluminum grille ceiling元/㎡Aluminum grille ceiling元/㎡Aluminum grille ceiling元/㎡Aluminum grille ceiling元/㎡ 。

 Aluminum grilleCeiling process and operation process
1. Determine the height and use ink to play the high horizontal line on the wall;
2. Fix the hanging rib on the top with an iron expansion bolt, and keep the light steel keel under the hanging rib level (if the grid span does not exceed 3 meters, the hanging rib is not needed);
3. Use cement nails to nail the aluminum corner line along the horizontal line;
4. Put the aluminum grille on the ground to complete the assembly;

5. Put the assembled grid ceiling on the aluminum angle iron, and tie the middle position directly on the light steel keel with thin iron wire;

⑴弹线 用水准仪在房间内每个墙（柱）角上抄出水平点（若墙体较长， 黑/白色烤漆 150*150*0.6 ㎜厚*42 ㎜高 55.00 黑/白色烤漆 150*150*0.4 ㎜厚*42 ㎜高 48.00 黑/白色烤漆 150*150*0.6 ㎜厚*35 ㎜高 50.00 黑/白色烤漆 150*150*0.4 ㎜厚*35 ㎜高 42.00 中间也应适当抄几个点） 弹出水准线 ， （水准线距地面一般为 500 ㎜） ， 从水准线量至吊顶设计高度，用粉线沿墙（柱）弹出水准线，即为吊 顶格栅的下皮线。同时，按吊顶平面图，在混凝土顶板弹出主龙骨的 位置。主龙骨应从吊顶中心向两边分，最大间距为 1000 ㎜，并标出 吊杆的固定点，吊杆的固定点间距 900 ㎜～1000 ㎜。如遇到梁和管 道固定点大于设计和规程要求，应增加吊杆的固定点。

 ⑵固定吊挂杆件 采用膨胀螺栓固定吊挂杆件。可以采用ф6 的吊杆。吊杆可以采 用冷拔钢筋和盘圆钢筋，但采用盘圆钢筋应采用机械将其拉直。吊杆 的一端同 L30*30*3 角码焊接， （角码的孔径应根据吊杆和膨胀螺栓的 直径确定）另一端可以用攻丝套出大于 100 ㎜的丝杆,也可以买成品 丝杆焊接。制作好的吊杆应做防锈处理，吊杆用膨胀螺栓固定在楼板 上，用冲击电锤打孔，孔径应稍大于膨胀螺栓的直径。 

⑶ Light steel keel installation Light steel keel shall be hung on the boom (if the ceiling is low, this process can be omitted and the next process can be carried out directly). Generally use 38 light steel keel, spacing 900 ㎜ ~ 1000 ㎜. The light steel keel shall be installed parallel to the long direction of the room, and shall be arched at the same time. The arching height shall be 1/200~1/300 of the room span. The cantilever section of light steel keel should not be greater than 300 ㎜, otherwise the boom should be added. The extension of the main keel shall be butted, and the butt joints of adjacent keels shall be staggered. The light steel keel shall be basically leveled after being hung. For the suspended ceiling with a span of more than 15m, a large keel shall be added on the main keel every 15m, and the vertical main keel shall be welded firmly.
⑷ Installation of spring sheet: connect the suspension rod with the light steel keel (if the ceiling is low, the spring sheet can be directly installed on the suspension rod to omit this process), with a spacing of 900 ㎜ ~ 1000 ㎜, and then clamp the spring sheet on the suspension rod.
(5) Assembly of the main and auxiliary bones of the grille The main and auxiliary bones of the grille are pre-installed below according to the requirements of the design drawings.

(6) Grille Installation The pre-installed grille ceiling is lifted through the main bone hole with a hook, and the whole grille ceiling is connected and adjusted to horizontal.
