High spacing lightgage steel joist furred ceiling systems stabilisation
?
Technical field
the present invention relates to surpass 1.5 meters technical field of construction to decorating the furred ceiling absolute altitude at the bottom of the building structure floor in technical field of building construction, the especially decoration construction.
Background technology
high building floor height space.Traditional construction way of constructing has: be connected between building structure top and the channel system; Comprise a vertical steel frame (being generally the 4# angle steel) and two oblique steel frames (being generally the 4# angle steel); The upper end of wherein vertical steel frame all has been welded to connect a fixedly shaped steel, each fixedly shaped steel all be connected on the structure top through expansion bolt; Said two oblique steel frame one ends symmetry be connected on the vertical steel frame (support angle should 30 ~ 45 spend between); The other end has been welded to connect a fixedly shaped steel; Each fixedly shaped steel all be connected on the structure top through expansion bolt, weld with the channel system bottom of vertical steel frame.This apparatus structure manufacturing cost and construction cost are high, and steel frame system of whole load system load is big.
Summary of the invention
the present invention seeks to: provide a kind of system load little, lower-cost high spacing lightgage steel joist furred ceiling systems stabilisation.
Technical scheme of the present invention is:
a kind of high spacing lightgage steel joist furred ceiling systems stabilisation comprises the keel furred ceiling, it is characterized in that, between keel furred ceiling and building structure top, is connected with several vertical suspension rods, and said suspension rod outside is with a steel sleeve; The diagonal angle up and down of adjacent two steel sleeves is connected with round steel, and said round steel two ends and steel sleeve welding are fixing, get rid of tightly with turnbuckle at the intersection point place of said round steel; Adjacent round steel intersection point spacing is a 3-4 suspension rod spacing.
are preferred, and said suspension rod upper end is connected in the building structure top through expansion tube, and said suspension rod lower end is connected in the keel ceiling system through hanging piece.
are preferred, and said suspension rod is that diameter is the system body screw thread suspension rod of 8mm.
are preferred, and said firm casing diameter is 12.7mm, and wall thickness is 0.6mm.
are preferred, and said round steel diameter is more than or equal to 10mm.
are preferred, and said turnbuckle is enclosed 00 a type screw-button.
Advantage of the present invention is:
the present invention makes the lightgage steel joist ceiling system form firm structure; Thereby guarantee the stability of whole lightgage steel joist ceiling system framework; Prevent that furred ceiling from rocking or flexural deformation in air pressure change, cause the later stage Thistle board to be difficult for crack, cracking.This invention has reduced manufacturing cost, has lowered the whole system load.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is the high spacing lightgage steel joist of a present invention furred ceiling systems stabilisation structural representation.
wherein: 1, building structure top, 2, the keel furred ceiling, 3, suspension rod, 4, steel sleeve, 5, round steel, 6, the round steel intersection point, 7, expansion tube, 8, hanging piece.
The specific embodiment
further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the present invention is described and are not limited to limit scope of the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete engineering, and not marked implementation condition is generally the condition in the normal experiment.
a kind of high spacing lightgage steel joist furred ceiling systems stabilisation comprises keel furred ceiling 2, between keel furred ceiling 2 and building structure top 1, is connected with several vertical suspension rods 3, and said suspension rod 3 outsides are with a steel sleeve 4; The diagonal angle up and down of adjacent two steel sleeves 4 is connected with round steel 5, and said round steel 5 two ends and steel sleeve 4 welding are fixing, get rid of tightly with turnbuckle at intersection point 6 places of said round steel; Adjacent round steel intersection point 6 spacings are 3-4 suspension rod spacing.
In
preferred embodiment of the present invention, said suspension rod 3 upper ends are connected in building structure top 1 through expansion tube, and said suspension rod 3 lower ends are connected in keel ceiling system 2 through hanging piece.
In
preferred embodiment of the present invention, said suspension rod 3 is the system body screw thread suspension rod of 8mm for diameter.
In
preferred embodiment of the present invention, said firm sleeve pipe 4 diameters are 12.7mm, and wall thickness is 0.6mm.
In
preferred embodiment of the present invention, said round steel 6 diameters are more than or equal to 10mm.
In
preferred embodiment of the present invention, said turnbuckle is enclosed 00 a type screw-button.
above to be shown and has described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the manual just explains principle of the present invention; The present invention also has various changes and modifications under the prerequisite that does not break away from spirit and scope of the invention, and these variations and improvement all fall in the scope of the invention that requires protection.
