The specific embodiment
The first embodiment of the present invention is presented among Fig. 3.
To this embodiment, structure cover panels 10 comprises the roll forming elongate steel sheet 12 with top side 14 and bottom side 16.Cover panels 10 is section bars and comprises that top flange 40, base flange 42, interconnection web elements 44, side form part 46 that these parts make adjacent panel settle side by side in overlapping mode.
Use this embodiment of the present invention, girth member 20 is the cylindrical bars with circular cross section.But the girth member with shape of cross section of broad type can be used to be fit to specific manufacturing and designing requirement.
Use this embodiment of the present invention, girth member 20 is connected to the bottom side of described steel plate 12 and is placed in the chamber that top flange 40 middle ribs 48 by panel 10 are limited.Described layout makes that essence contacts between described steel plate 12 and the girth member 20.The essence contact helps to reinforce the intensity that the shearing force between described girth member 20 and the described steel plate 12 connects.In addition, described layout makes girth member 20 not contact with the concrete on the top that is cast to panel 10.This means the possible problem that reduces of the straight skidding resistance that does not have cover panels after hardening of concrete.In addition, girth member 20 does not disturb any common constructing operation of carrying out at the top of cover panels, for example settles girth member and casting and concrete is carried out compacting.
(not shown) in additional embodiments of the present invention, girth member 20 can be connected in the selected zone of top side 14 of described plate 12.
Girth member can be placed on the whole length of panel 12 on the short length in the selected zone continuously or alternatively, to improve economy and the passage interference of avoiding with vertical building service.
Two examples with panel of the position of part of girth member 20 and length are presented among Fig. 6,7 and 8 by signal.Fig. 6 is the viewgraph of cross-section of position of the web elements of explanation girth member relative panel 12.Girth member 20 partly extends along the length of described plate 12 and leaves.Fig. 7 has shown that the position of the girth member 20 of panel among Fig. 6 wherein is selected to be positioned at panel with supporting on 30.Fig. 8 shown the position (and length) of the girth member 20 of panel among Fig. 6 wherein selected with at panel with the layout between the support member 30.
Girth member 20 can be by the various material manufacturings that comprise steel or senior synthetic materials.
Girth member 20 can by comprise bonding, weld, be threaded, the distinct methods of stickfast and crimping is bonded on the described steel plate 12.
Preferably, girth member 20 can be soldered to or is bonded on the described steel plate 12 to produce needed connection.
Girth member 20 is connected to steel plate 12 can be taken place after the roll forming process that forms profile plate 12.Alternatively, plate 12 can be reinforced (by reinforcement by connection part 20) before to described plate roll forming.
As implied above, the bonding strength between girth member 20 and the described plate 12 is very important when cover panels is born the top load of wet concrete.Use aforesaid embodiment and other embodiment of the present invention, shearing force connects or the part shearing force connects and may reside on the critical cross-section fully.
" critical cross-section " is interpreted as that herein the design moment of deflection is maximum cross section to the ratio (perhaps when to the shearing design, design shear stress is to the ratio of design shearing force capacity) of design moment capacity to term.(this is the cross section that lost efficacy and will disperse.)
If critical cross-section may show when relatively low part shear stress connects that longitudinal shear destroys and can promptly be avoided by adjusting design load in the framework stage before hardening of concrete.Suppose that separately the moment capacity of the girth member 20 of effect compares with the moment capacity of the composite component of girth member 20 and described steel plate 12 hour, (this is such to the preferred embodiments of the present invention, then required shearing force connects degree appropriateness higher (approximately being 30% or higher) but to all other embodiment of the present invention but not necessarily).Otherwise girth member 20 can not be made significant contribution in the framework stage to the moment capacity of cover panels 10.
According to circumstances, it is so important that the bonding strength between girth member 20 and the described steel plate 12 is unlike in synthesis phase (promptly after concrete hardening and composite plate are formed).In this stage, usually bending stiffness and the ultimate strength that composite plate is provided become very important factor by cover panels 10 and the caused mechanical interlocking of hardened concrete (per unit length panel).Like this, the gummed that girth member 20 and described slab 12 are linked together disconnect or these parts between the forfeiture of the validity that connects of other form will not be a relevant problem.
Girth member 20 can be attached in any combination to the top side 14 of cover panels and the selected zone of bottom side 16.In case will keeping leaving concrete curing usually, girth member 20 promptly has zone (for example, having the web that is pressed into projection wherein) on the top side 14 of mechanical resistance of known, higher level.Importantly, the connection of the longitudinal shear power between girth member 20 and the described steel plate 12 must be able to make and avoid longitudinal shear to destroy in the framework stage.
Girth member 20 can be placed on the various discrete position of steel plate 12.The example of diverse location is presented among Fig. 4,5 and 6.
With reference to Fig. 5, girth member 20 is connected to the flange 40,42 of steel deck-plate with second moment of increase around the zone of main longitudinal axis, and increases the bending stiffness of cover panels to vertical load thus especially.
The moment capacity of critical zone also can cause the distribution of vertical bending compression stress of the early stage local buckling of cover plate flange and/or web to increase by change---and for example referring to Fig. 4, this is the situation that this cross section is in positive curve.
Asymmetric section bar around main horizontal axis can be reinforced with the compression of raising flange and the balance between the tensile capacities.An example of this situation is presented among Fig. 3, from wherein reinforcing balance between the cross section flange that narrower top flange increased top and wideer base flange 40,42 as can be seen.
Reinforcing web elements 44 also can improve shearing force (and crooked), and capacity---with reference to Fig. 6, this especially is very useful in internal support regions.
The profile shapes of wideer kind and girth member 20 can be used to reach specific designing requirement.Example is presented among Fig. 9,10 and 11.
Structural iron cover panels according to the present invention provides some or all following advantages.
● by settling the more effective structure design of girth member, this is its best effect.This has overcome a basic problem rolling steel plate---and the common thickness of described plate is constant around profile perimeter.
● longer cover plate span or thicker plate or beam or bigger working load.This has increased the scope of the application that the special cover plate of maximum thickness of slab wherein can be actually used.
● by they and more cheap are reinforced rod or the combined economy that improves the roll forming steel plate of plate such as hot rolling.
In order to prevent concrete contact girth member 20, parts can be contained in to be rolled than in the less additional rib in the steel deck-plate or the vertical bracing piece (for example referring to Fig. 3 and 9).Additional longitudinal rib can be of similar shape to assist their be connected (for example referring to Fig. 9) with girth member.
Feature of the present invention is that suitable structural iron cover panels can have or not have additional reinforcement and use.This uses additional reinforcement to increase economy when need allowing.The embodiment of shown reinforced closed rib cover panels has shown this point among Figure 10,11.
