The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete better embodiment.
As shown in Figure 2, profiled sheet 2 comprises some fins 4 and the some bottom panels 5 of interlaced setting, and every fin 4 includes a top panel 8 and two sidewalls 9 that are arranged at top panel 8 both sides.
In the firm frame construction of large span, as end face, designer can adopt bi-curved pattern conventionally, then adopts the composite floor of profiled sheet 2.In structural configuration, all capital absolute altitudes all drop in the hyperboloid of roofing, and then according to these definite capital points, by several girder steels of just putting 1 of certain pitch arrangement, profiled sheet 2 is laid on these girder steels of just putting 1.Because the initial absolute altitude at girder steel 1 two ends is different, therefore cause the profiled sheet 2 of laying for tilting, along rib, to tilting profiled sheet 2, be connected with shelving of the girder steel 1 of just putting and by method of attachment of the present invention, be achieved just, specific as follows.
Tilting profiled sheet with just put the method for attachment of shelving of girder steel, comprise the following steps.
The first step, fin 4 joint-cuttings: as shown in Figure 1, when tilting profiled sheet 2 is when the direction of fin 4 is shelved on several girder steels of just putting 1, at the two ends of each girder steel 1 width, profiled sheet 2 respectively forms a tie point 11 by the two ends at each girder steel 1.At these tie point 11 places, all every fin 4 of profiled sheet 2 is carried out to joint-cutting processing along vertical ribs 4 directions, thereby make every fin 4 all be formed with several crest otch 10, now, the bottom of profiled sheet 2 is by the complete docile in the top with each girder steel 1.The degree of depth of each crest otch 10 preferably equates with the height of fin 4, makes profiled sheet 2 more complete with the docile of girder steel 1, is also convenient to the bending of follow-up profiled sheet 2 simultaneously.In this step, it should be noted that the every bottom panel 5 of profiled sheet 2 all can not have joint-cutting.
Second step, profiled sheet 2 bends and uses peg 3 fixing: the profiled sheet 2 that the first step completes, can manually relatively easily bend, after bending, with several pegs 3, profiled sheet 2 is fixed.Peg 3 preferred weld are fixed on the some bottom panels 5 of profiled sheet 2, like this, and fixation, and do not affect follow-up reinforcement operation.
The 3rd step, crest otch 10 reinforcement: each crest otch 10 of the profiled sheet in second step 2 is all carried out to reinforcement with at least one plate face stiffening plate 6, preferably with three plate face stiffening plates 6, carry out reinforcement, as shown in Figure 2, three 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.Like this, the joint-cutting of each crest otch 10 will all be hidden by plate face stiffening plate 6, and reinforcement is even.
Above-mentioned every plate face stiffening plate 6 is all fixed by several structure nails 7, is preferably 8, is evenly distributed on the both sides of every plate face stiffening plate 6.
The thickness of above-mentioned every plate face stiffening plate 6 equates with the thickness of profiled sheet 2.Like this, the intensity of the profiled sheet after reinforcement 2 is by unaffected.Certainly, also can, according to the actual needs that bear weight, select the plate face stiffening plate 6 of suitable thickness.
The 4th step, load test step: profiled sheet 2 tops that complete in the 3rd step, place weight and carry out load test.It is stupefied that between profiled sheet 2 and weight, advance expenditure has several wood.Like this, weight loads and will all drop on profiled sheet 2.According to actual needs, this step can not done yet.The application is through field trial, and when the width of every fin 4 is 75mm, when wall thickness is 1.2mm, weight is loaded into 250Kg/ square, and profiled sheet 2 is not distortion still, and intensity meets the requirements.
After the method that the present invention adopts above-mentioned " first cut out afterwards and stitch ", the complete docile of energy between tilting profiled sheet 2 and the girder steel 1 of just putting; The reinforcement of crest otch 10, makes the bearing capacity of the profiled sheet 2 after joint-cutting unaffected, makes it to meet the requirement of simulation curved surface state, thereby profiled sheet 2 can be applied in hyperboloid composite floor.
