High spacing lightgage steel joist furred ceiling systems stabilisation
Technical field
The present invention relates to technical field of building construction, especially surpass 1.5 meters technical field of construction to decorating the furred ceiling absolute altitude at the bottom of the building structure floor in the 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), wherein the upper end of vertical steel frame all has been welded to connect a fixedly shaped steel, each fixedly shaped steel all be connected on the structure top by expansion bolt; Described two oblique steel frame one ends are symmetrically welded and are connected on the vertical steel frame (support angle should between 30 ~ 45 degree), the other end has been welded to connect a fixedly shaped steel, each fixedly shaped steel all be connected on the structure top by expansion bolt, weld with the channel system bottom of vertical steel frame.This apparatus structure manufacturing cost and construction cost height, 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, is connected with several vertical suspension rods between keel furred ceiling and building structure top, and described 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 described round steel two ends and steel sleeve welding are fixing, get rid of tightly with turnbuckle at the intersection point place of described round steel; Adjacent round steel intersection point spacing is 3-4 suspension rod spacing.
Preferably, described suspension rod upper end is connected in the building structure top by expansion tube, and described suspension rod lower end is connected in the keel ceiling system by hanging piece.
Preferably, described suspension rod is that diameter is the stack shell screw thread suspension rod of 8mm.
Preferably, described steel sleeve diameter is 12.7mm, and wall thickness is 0.6mm.
Preferably, described round steel diameter is more than or equal to 10mm.
Preferably, described turnbuckle is enclosed 00 type screw-button.
Advantage of the present invention is:
The present invention makes the lightgage steel joist ceiling system form firm structure, thereby guarantees the stability of whole lightgage steel joist ceiling system framework, prevents that furred ceiling from rocking in air pressure change or flexural deformation, causes 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 drawings and Examples the present invention is further described:
Fig. 1 is the high spacing lightgage steel joist of the 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
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit the scope of the invention for explanation 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, is connected with several vertical suspension rods 3 between keel furred ceiling 2 and building structure top 1, and described 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 described round steel 5 two ends and steel sleeve 4 welding are fixing, get rid of tightly with turnbuckle at intersection point 6 places of described round steel; Adjacent round steel intersection point 6 spacings are 3-4 suspension rod spacing.
In the preferred embodiment of the present invention, described suspension rod 3 upper ends are connected in building structure top 1 by expansion tube, and described suspension rod 3 lower ends are connected in keel ceiling system 2 by hanging piece.
In the preferred embodiment of the present invention, described suspension rod 3 is the stack shell screw thread suspension rod of 8mm for diameter.
In the preferred embodiment of the present invention, described steel sleeve 4 diameters are 12.7mm, and wall thickness is 0.6mm.
In the preferred embodiment of the present invention, described round steel 6 diameters are more than or equal to 10mm.
In the preferred embodiment of the present invention, described turnbuckle is enclosed 00 type screw-button.
More than show and 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 above-described embodiment and the manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.
