Abstract
The invention discloses a kind of pure steel joist suspended ceiling, it comprises Die Ji moulding basic unit, gypsum plank and plaster line (4), main joist (2), Die Ji moulding basic unit comprises L-type keelson (1), rider keel (3), rider keel (3) forms the skeletal support of Die Ji moulding basic unit, and the inner corner trim of Die Ji moulding basic unit and/or external corner adopt elongated L-type keelson (1) to connect; The surface layer of Die Ji moulding basic unit covers gypsum plank and plaster line (4), forms overall furred ceiling; Rider keel (3) is connected with main joist (2).Main joist (2) is fixed to roof by screw mandrel (5).L-type keelson (1) and rider keel (3) are fixed by rivet.The present invention can ensure end face fire protection requirement, reduces the problems such as the content of formaldehyde that brought by plank base of end face, and cracking, distortion that plank base brings can be solved, be easily corroded, a row common quality defect such as to damage by worms.
Description
Technical field
The present invention relates to the steel joist suspended ceiling technology of modern architecture fitting-out work, especially relate to a kind of pure steel joist suspended ceiling.
Background technology
At present, domestic and international lightgage steel joist, plaster tablet suspended ceiling have the position of moulding, basic unit all adopts plank base (woodwork plate, veneer etc.), along with constantly not only developing of repairs profession, row common quality defects such as adopting in furred ceiling plank base to make the requirement that moulding cannot meet industry development gradually, the suspended ceiling modeling that plank base makes easily produces cracking, distortion, be easily corroded, damage by worms; Further, plank base also can bring the problem such as content of formaldehyde, fire prevention difficulty.
Summary of the invention
The object of the invention is: a kind of pure steel joist suspended ceiling is provided, end face fire protection requirement can be ensured, reduce the problems such as the content of formaldehyde that brought by plank base of end face, and cracking, distortion that plank base brings can be solved, be easily corroded, a row common quality defect such as to damage by worms.
Technical scheme of the present invention is: a kind of pure steel joist suspended ceiling, it comprises Die Ji moulding basic unit, gypsum plank and plaster line, main joist, described Die Ji moulding basic unit comprises L-type keelson, rider keel, described rider keel forms the skeletal support of Die Ji moulding basic unit, and the inner corner trim of Die Ji moulding basic unit and/or external corner adopt elongated L-type keelson to connect; The surface layer of described Die Ji moulding basic unit covers gypsum plank and plaster line, forms overall furred ceiling; Rider keel is connected with main joist.
Below technique scheme is further expalined:
Described main joist is fixed to roof by screw mandrel.
Described L-type keelson and rider keel are fixed by rivet.
Each support unit spacing 400mm of the skeletal support that described rider keel is formed.
Described screw mandrel and main joist connection end distance are not more than 300mm.
Described rider keel and main joist connection end size are not more than 200mm.
Advantage of the present invention is:
1, pure steel joist suspended ceiling of the present invention, pure lightgage steel joist is adopted to make, the plank base broken traditions makes the technique of end face moulding, achieve finishing furred ceiling and reach the fire protection requirement of A level, reduce the content of formaldehyde etc. that brought by plank base of end face, row common quality defects such as solving cracking, distortion that plank base brings, be easily corroded, damage by worms.
2, pure steel joist suspended ceiling can in back court batch machining, and job site is assembled after possessing mounting condition, effectively controls the construction period of furred ceiling operation.
3, adopt pure lightgage steel joist to make, effectively control plank base and use, meet the developing direction of current repairs profession green, environmental protection, low-carbon (LC).
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 be the specific embodiment of the invention fall a grade moulding base layer structure schematic diagram (oppositely);
Fig. 2 is the structural representation of the specific embodiment of the invention;
Fig. 3 is the mounting structure generalized section of the specific embodiment of the invention;
Wherein: 1 L-type keelson; 2 main joists; 3 rider keels; 4 gypsum planks and plaster line; 5 screw mandrels.
Detailed description of the invention
Embodiment: as shown in Figure 2 and Figure 3, a kind of pure steel joist suspended ceiling, it comprises Die Ji moulding basic unit, gypsum plank and plaster line 4, main joist 2, Die Ji moulding basic unit comprises L-type keelson 1, rider keel 3, rider keel 3 forms the skeletal support of Die Ji moulding basic unit, each support unit spacing 400mm of the skeletal support that rider keel 3 is formed; The yin, yang angle of Die Ji moulding basic unit adopts elongated L-type keelson 1 to connect.L-type keelson 1 and rider keel 3 are fixed by rivet.The surface layer of Die Ji moulding basic unit covers gypsum plank and plaster line 4, forms overall furred ceiling; Rider keel 3 is connected with main joist 2.Main joist 2 is fixed to roof by screw mandrel 5.
It is below the construction sequence of the present embodiment.
1, according to end face moulding node, adopt rider keel 3 to make to fall level, modeling skeleton supports, rider keel 3 spacing 400mm arranges, and falls level, the yin, yang angle of moulding all adopts elongated L-type keelson 1 to connect, adopt rivet to fix with rider keel 3.
2, in-site installation screw mandrel 5, main joist 2, screw mandrel 5 and main joist 2 connection end distance are not more than 300mm, and rider keel 3 and main joist 2 connection end size are not more than 200mm.End face falls level, moulding is connected with end face rider keel 3 in the pure lightgage steel joist making of being processed by back court, and yin, yang angle adopts L-type keelson 1, rivet is fixed, and surface layer covers gypsum plank and plaster line 4, forms overall furred ceiling.
The present invention replaces the plank base always adopted and makes the construction technology of falling level, moulding; Make it meet fire-protection rating and reach the requirement of A level, and can the problems such as a series of common faults brought by plank base be solved.
It should be pointed out that for the present invention through absolutely proving, also can have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment.Above-described embodiment is as just explanation of the present invention, instead of restriction.In a word, protection scope of the present invention should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
