Description of drawings
In order to help to understand essence of the present invention better, the preferred embodiment of metal decking and manufacture method thereof is only described by the mode of example with reference to the accompanying drawings.In the accompanying drawing:
Fig. 1 is the sectional view according to an embodiment of metal decking of the present invention;
Fig. 2 is the phantom drawing according to another embodiment of metal decking of the present invention;
Fig. 3 is the sectional view of the alternative fastener of metal decking.
The specific embodiment
As shown in Figure 1, metal decking 10 comprises: a pair of metal decking spare 12 and 14 adjacent, that sidepiece links to each other.Metal decking 10 is designed to be embedded into or be coated in the cement board, thereby forms roof or floor.
Have identical long and narrow cross sectional shape and C cross-sectional profiles as 12 with 14 adjacent metal paving element.This C shape cross section metal decking spare 12 comprises web 16 and a pair of relative flange 18 and 20.Metal decking as 12 has C shape cross-sectional profiles, and wherein, each flange 18 and 20 free edge part 22 and 24 are curved inwardly.In addition, each in the free edge part 22 and 24 comprises that separately lip is curved 26 and 28, and they arrange to such an extent that be parallel to corresponding flange 18 and 20 usually.So the metal decking spare as 12 and 14 has the cross sectional shape that substantial symmetry is arranged.
As shown in Figure 2, the web 16 of metal decking spare 12 is by longitudinally to the inboard prebuckling of metal decking spare 12.This metal decking spare 12 is the types shown in Fig. 1, but does not have the rib of longitudinal extension.This metal decking spare is embedded in the cement board (not shown) generally speaking, therefore can stride across longer not supported distance.In this example, the prebuckling of web 16 is as the vertical misalignment of web from the maximum of the plane survey of substantially flat, and the length of web 16 approximately is 0.6% with the form statement of percentage relatively.The web 16 that should be understood that vertical prebuckling is offset to flat surfaces under the effect of the effective weight of cement board at least in part.Advantageously, this vertical prebuckling provides minimum skew for the metal decking spare 12 of crossing over bigger distance.In this embodiment, metal decking spare 12 can be crossed over and reach about 5 meters not supported distance, and comprises the vertical prebuckling corresponding to about 30mm of 0.6%.This embodiment of the present invention can have 5 meters not supported span, and by contrast, the span with the conventional metals paving of vertical prebuckling is not 3 meters.
As shown in Figure 1, the web 16 of metal decking spare 12 in cross-sectional profiles on also inwardly prebuckling.In this example, the horizontal prebuckling of web 16 is as the skew of web from the maximum of the plane survey of substantially flat, and the width of web 16 is explained with the form of percentage relatively, approximately is 2%.In this example, the width of metal decking spare 12 approximately is 300mm, and is formed by the sheet metal rolling that thickness is approximately 1.2mm.
Flange 18 and 20 comprises the rib 30 and 32 of longitudinal extension respectively. Rib 30 and 32 rollings are formed in the lower part of each flange 18 and 20 contiguous webs 16.Rib 30 forms inside projection, and the shape of another rib 32 and relative rib 30 complementations, but points to the outside of paving element 12.This longitudinal rib 30 and 32 is aimed at,, can be connected together each other so that make adjacent rib 32 and 34 such as adjacent paving element 12 and 14.Therefore, the rib that connects together, as 32 and 34, constraint paving element 12 and 14 moving both vertically each other, and help the aligning of adjacent paving element 12 and 14.
By making 16 one-tenth corrugated of web, the vertical prebuckling in the web 16 of formation metal decking spare 12.This ripple (not shown) is by located lateral, and ground, the width top extension of crossing web 16.By cold rolling transverse wave is formed in the web 16, and enough " gently " providing reaches about 2% preferred vertically prebuckling.In case paving element forms C shape cross-sectional profiles, ripple can be formed in the smooth band or web 16 in.Perhaps, can form the ripple of web 16 with traditional cold rolling generation type by the corrugation rolls (not shown).
The adjacent metal paving element 12 of this embodiment and 14 securing members by a series of as 36 bolt form tighten together, and described securing member for example 18 and 20 is bonded together the adjacency of adjacent paving element 12 and 14 or adjacent flange.Securing member as 36 is longitudinally separated along the paving element as 12 and 14.Fig. 3 shows the fastening devices that the adjacent ribs in order to adjacent paving element of another kind of form is fixed together.In this alternative example, fastening devices is the form of elastic clip 38, and it with the adjacent free edge part of adjacent paving element 12 and 14, is bonded together as 22 and 24 releasedly.This elastic clip 38 is used as the replacement scheme as the securing member of bolt 36.The profile of elastic clip 38 and the free edge part 22 of arranging back-to-back and 24 is similar, and constructs to such an extent that make its inside bias voltage, links together to force adjacent ribs 18 and 20.Therefore, this elastic clip 38 becomes C shape profile substantially, and its free edge part outwards opens, to be easy to clamp respectively or install the free edge part 22 and 24 of adjacent ribs 18 and 20.
The conventional metals paving element is dissymmetrical structure normally, and wherein, relative flange is by respectively inwardly and outwardly-bent.So adjacent flange forms traditional metal decking by superposeing.The conventional metals paving has the trend that lost efficacy when standing load, and wherein, the flange of adjacent stack subsides or rotates to the web of one of them paving element.The adjacent flanges that should be understood that the adjacent metal paving element of this embodiment of the present invention is difficult for losing efficacy in this manner.
Those skilled in the art should be appreciated that the present invention described herein can have various changes and modifications except the embodiment that specifies.For example, the C shape cross-sectional profiles of paving element can vertically and/or laterally be changed to the inner prebuckling of metal decking according to metal decking spare.Metal decking spare in the alternative can be buied in Australia, trade mark is the type of BONDEK, and the type has the rib of one or more upright and longitudinal extensions.Variation that all are such and modification should be considered to be in by above stated specification to be determined within the scope of the present invention of its essence.
In aforementioned summary of the present invention, except because the required literal of language performance and necessary implication, it is identical with the implication of " comprising " that word " comprises ", that is, specifically feature can be associated with the further feature among the various embodiment of the present invention.
