Detailed description of the invention
The present invention is further detailed explanation with concrete better embodiment below in conjunction with the accompanying drawings.
As in figure 2 it is shown, profiled sheet 2 includes some fins 4 and some pieces of bottom panels 5, two sidewalls 9 that every fin 4 all includes one piece of top panel 8 and is arranged at top panel 8 both sides of interlaced setting.
In the firm frame structure of large span, such as end face, designer would generally use bi-curved pattern, then use the composite floor of profiled sheet 2.In structure is arranged, all of capital absolute altitude all falls within the hyperboloid of roofing, then according to these capital determined points, arranges that several girder steels 1 just put, profiled sheet 2 are laid on these girder steels 1 just put by certain spacing.Owing to the initial absolute altitude at girder steel 1 two ends is different, thus cause the profiled sheet 2 of laying for tilting, along rib shelving to be connected and be exactly based on the method for attachment of the present invention and be achieved to tilting profiled sheet 2 and the girder steel 1 just put, specific as follows.
A kind of tilting profiled sheet with just putting girder steel shelve method of attachment, comprise the following steps.
The first step, fin 4 joint-cutting: as it is shown in figure 1, when tilting profiled sheet 2 is shelved on several girder steels 1 just put along the direction of fin 4, at the two ends of each girder steel 1 width, the two ends at each girder steel 1 are respectively formed a junction point 11 by profiled sheet 2.At these junction points 11, all along vertical ribs 4 direction, every fin 4 of profiled sheet 2 being carried out joint-cutting process, so that every fin 4 is each formed with several crest otch 10, now, the bottom of profiled sheet 2 is by the complete docile in top with each girder steel 1.The degree of depth of each crest otch 10 is preferably equal with the height of fin 4, makes profiled sheet 2 more complete with the docile of girder steel 1, also allows for the bending of follow-up profiled sheet 2 simultaneously.In this step, it should be noted that every piece of bottom panel 5 of profiled sheet 2 all can not have joint-cutting.
Second step, profiled sheet 2 bends and uses peg 3 to fix: the profiled sheet 2 that the first step completes, and can the most relatively easily bend, after bending, is fixed by profiled sheet 2 with several pegs 3.Peg 3 preferred weld is fixed on some pieces of bottom panels 5 of profiled sheet 2, so, and fixation, and do not affect follow-up reinforcement operation.
3rd step, crest otch 10 reinforcement: each crest otch 10 of the profiled sheet 2 in second step is all carried out reinforcement with at least one piece of plate face stiffening plate 6, preferably carry out reinforcement with three pieces of plate face stiffening plates 6, as in figure 2 it is shown, three pieces of plate face stiffening plates 6 are separately fixed on the top panel 8 of every fin 4 and two sidewalls 9 of every fin 4.So, the joint-cutting of each crest otch 10 will all be hidden by plate face stiffening plate 6, and reinforcement is uniform.
Above-mentioned every piece of plate face stiffening plate 6 is all fixed by several structures nail 7, preferably 8, is evenly distributed on the both sides of every piece of plate face stiffening plate 6.
The thickness of above-mentioned every piece of plate face stiffening plate 6 is equal with the thickness of profiled sheet 2.So, the intensity of the profiled sheet 2 after reinforcement is by unaffected.It is of course also possible to according to the actual needs bearing weight, select the plate face stiffening plate 6 of suitable thickness.
4th step, load test step: profiled sheet 2 top completed in the 3rd step, place weight and carry out load test.Between profiled sheet 2 and weight, advance expenditure has several wood stupefied.So, weight loads and will fully fall on profiled sheet 2.According to actual needs, this step can not also be done.The application is through scene test, when the width of every fin 4 is 75mm, and when wall thickness is 1.2mm, weight is loaded into 250Kg/ square, and profiled sheet 2 does not the most deform, and intensity meets the requirements.
After the present invention uses the method for above-mentioned " first cut out and stitch afterwards ", can complete docile between tilting profiled sheet 2 and the girder steel 1 just put；The reinforcement of crest otch 10, the bearing capacity making the profiled sheet after joint-cutting 2 is unaffected, makes it to meet the requirement of simulation curved surface state, so that profiled sheet 2 can be able to popularization and application in hyperboloid composite floor.
