Description

Covering

The present invention relates to covering, particularly, relate to the covering that connects side by side.

The present invention introduced is sheet material about interlocking, they are connected to each other to form the covering of roof system/ceiling by longitudinal edge, particularly form the roof system/ceiling covering that forms with sheet metal, but the present invention is not limited only to above-mentioned application, can also be used for beating wall equally, decorate and other occasion that need cover, they also can be made by the sheet material of plastics or other material.

Common sheet metal roof system covering is made up of with mutual topped being arranged side by side in its marginal portion the ripple sheet material element of one group of metal.These elements are typically secured to the spaced-apart batten of horizontal spreading, on purlin or other support member, and by nail, bolt or other securing member their are inserted in sheet material and with batten and are connected.

In a nearest period, a kind of " smooth " or " barring " covering have been developed again.These coverings have the web of the substantially flat that is referred to as " base plate " and usually along the edge of a wing of its each longitudinal edge projection, also can contain one or several longitudinal extension on the web usually and to the enhancing rib of upper process.

In roof structure, these coverings all are that the edge of the edge of the element element adjacent with another overlaps and discharging side by side.Usually a marginal portion of each element is a positive rib component form and another marginal portion is cloudy rib component form.In when assembling, positive rib member is with interlock fit form and cloudy rib component adaptation, with prevent element perpendicular to along the disengaging on this both direction longitudinally of described member.Securing member that the common nationality of these elements helps use always or buried clip are fastened on the batten.Buried clip also is attached on the batten and topped by element institute usually.These clips have the bead that protrudes upward with suitable with the bottom of element rib and engage.

Though the construction profile uniformity of buried clip does not have clumsy fastening end, exposed and be similar to the sort of inaesthetic surface of securing member commonly used in its bottom.At balcony, goods shed, freight depot, the warehouse, garden, it can be as roof system again as ceiling usually to require a kind of covering assembly in the construction of bicycle shed and other building structure.In these cases, batten, purlin and other supporting structure part just may be by in sight significantly.For this reason, also consider economic factor, just need under the uniformity prerequisite of considering as whole with the desired intensity of structure, put batten to such an extent that separate as far as possible.But this just means the middle section between two adjacent battens, can not get on the suitable segment length of covering supporting and thereby the inclination of sinking.Sink to be owing to surpassed between the adjacent batten or unsuitable length of span caused, in addition, for reducing cost, usually according to adopting the thinnest steel board to make covering under the essential structural strength.But lamella elements relatively moves sometimes, and as a whole covering deflection meeting causes permanent distortion between the batten that supports.In order to make the risk minimum that this thing happens, it is short that the length of span will keep, and short length of span also can make sagging risk reach minimum.In most of Application in Building distortion with sink because can clearly see, be can not be received, therefore just require to develop a kind of roof system/ceiling covering assembly structure obviously longer than the length of span of roof system covering commonly used.

Even, especially adopting the inclination that is limited in the element between the span that is connected to each other of longitudinally extending rib member between the adjacent covering, but have been found that, in the prior art, after the span length of coverings for example surpasses 3 meters, still can not provide suitable rigidity so that the tilt quantity on the span is limited on the acceptable level.

The purpose of this invention is to provide the covering after a kind of improve and the connector of covering, they can overcome or alleviate above-mentioned such-and-such shortcoming significantly.

According to the present invention, a kind of covering is provided, it can be used for the assembly of covering, described covering has web and longitudinally extending edge, wherein a lateral edges has the cloudy rib member that stretches upwards and the opposite side edge has the positive rib member that stretches upwards makes it to enter in the cloudy rib member of another covering, and after so entering, can connect covering side by side with locking, be characterized in after so assembling a kind of cross section of the common formation of interconnected rib member.

This closed circuit is preferably with the leg-of-mutton shape of a kind of inversion.Common this triangle is most equilateral triangle or isosceles triangle.

This closed circuit is preferably come closed by fixing device.Fixing device can stop covering horizontal moving at least in one direction.

Fixing device preferably adopts the form of tenon and channel member in addition.

Can be provided with longitudinally extending groove on sun rib or the cloudy rib member, then be provided with longitudinally extending tenon on the member of another rib and make it when assembling, can stretch into adaptedly or received and go down with this continuous adjacency by the groove of adjacent covering.In when assembling, tenon and groove make by interconnected positive rib member and cloudy rib loop that member forms, and fastened connector and make nappe horizontal mobile perpendicular on the direction on the nappe plane at least.

Described groove is preferably continuously along stretching on the length of covering.

Tenon preferably also is continuously along stretching on the length of covering, and still, in some embodiments, tenon also can be discontinuously along stretching on the length of covering.That is to say that for example tenon can be formed along the short tenon that separates regularly on the covering length by one group.In one embodiment of back, groove can be that the form along the one group of short groove that stretches discontinuously on the covering length forms, and each short groove also is to separate regularly with the standoff distance identical with short tenon, and short tenon can alignment thereof discharging location with short groove when assembling like this.

Best, groove is formed on the bottom of positive rib member, and tenon also is formed on the bottom of cloudy rib member, and groove is the same with tenon to have the identical distance that separates with the covering plane.

The present invention also provides a kind of assembly of covering, and it is made up of one group of covering above-mentioned according to the present invention, wherein covering all be by positive rib member overlapped by the cloudy rib member of adjacent covering and engage with locking and side by side discharging form.

The present invention also provides a kind of connector, and it is made up of a pair of covering above-mentioned according to the present invention, and its positive rib member is engaged and discharging formation side by side by the cloudy rib member overlapping and the locking ground of adjacent covering.

Roof system/ceiling element shown in Figure 1 can be a kind of coated steel plate, has longitudinally extending positive rib member 2 along having longitudinally extending cloudy rib member 3 on the longitudinal edge of plate on another longitudinal edge, therebetween by 1 interconnection of smooth web.Web 1 has smooth plate part between the longitudinal edge on described two, it is in minimum position as roof system/ceiling element the time, also have a pair of longitudinally extending little enhancing rib 4 that parallels and separate to upper process on the described flat so that smooth plate part is played humidification.

Overlay is to make with the steel plate of 0.42 millimeter base metal thickness (BMT).Overlay can form by format roll is rolling.Also can make with methods such as punching press or continuous punching presses.

In the example of being introduced, the offset rib that stretches upwards 4 on the web 1 is projection on web plane for example about 4 millimeters only, is roughly planar shape in order to keep web 1.Cloudy rib member 3 protrudes in about 45 millimeters of top, described plane, about 35 millimeters of the width of cloudy rib member 3, about 33 millimeters of the width of positive rib member 2, about 254 millimeters of the width of web 1.

Sun rib member 2 is made up of a rib that stretches upwards, rib outwards forms ramp portion 6 earlier, also form a groove 8 therein in conjunction with a vertical component 7 again, and then inside the stretching, extension forms parts 9 above web 1, outwards stretch the positive edge of a wing 10 of formation again, it has trailing edge 11 and the leading edge 12 of returning the lip formula to stretch inwards downwards.Give prominence to outside web 1 on the described positive edge of a wing 10.8 length along sheet material of groove stretch continuously.

Cloudy rib member 3 also is made up of a rib that stretches upwards, rib outwards forms ramp portion 13 earlier, again in conjunction with a ramp portion inwards 14 that is positioned at web 1 top, and also has trailing edge 16 and with the cloudy edge of a wing 15 of the outside stretching, extension of the leading edge 17 of the form of recurrence part that stretches inwards downwards and the antelabium 18 that outwards stretches again, also give prominence to outside web 1 on the described cloudy edge of a wing 15.Outside ramp portion 13 has just formed outwards outstanding tenon member 19 with combining of ramp portion 14 inwards.Tenon 19 stretches continuously along the length of sheet material, and certainly, in certain embodiments, tenon also can be discontinuously along stretching on its length.

Sun rib member 2 and cloudy rib member 3 have been formed can interconnected member, and wherein when assembling, the positive rib member 2 on sheet material can enter in the cloudy rib member 3 of adjacent similar sheet material, and sheet material is engaged.The leading edge 12 on the sun edge of a wing 10 has entered in the opening in the hole that is formed by the cloudy edge of a wing 15, and is directed on the trailing edge 16 on the cloudy edge of a wing 15, so the trailing edge 11 on the positive edge of a wing 10 is just adaptive and meshed fast with 17 of the leading edges on the cloudy edge of a wing 15.In order to make engagement fast, when the trailing edge 11 on the positive edge of a wing 10 was inserted in the opening in hole 20, the inside expandable part of the leading edge 17 on the cloudy edge of a wing 15 just flicked from the trailing edge 16 on the cloudy edge of a wing 15.In when assembling, the top on the positive edge of a wing 10 just contacts with the bottom on the cloudy edge of a wing 15 like this, and contact portion flatly is close to together mutually, and together fastening them by the quick adaptive member on the cloudy edge of a wing 15.This mode of intermeshing provides the interference engagement between positive rib member and

cloudy rib member

2,3.

The lip 18 of the outside stretching, extension on the cloudy edge of a wing 15 helps the leading edge 12 of the positive wing 10 to enter in the opening in hole 20, also helps manually to open when assembling the insertion of described opening with the trailing edge 11 that is convenient to the positive edge of a wing 10.In addition, when lip 18 moved, the setting of lip 18 also helped to strengthen the lock fit of connector.

As mentioned above, groove 8 is formed at the bottom of positive rib member 2, and tenon 19 also is formed at the bottom of cloudy rib member 3, and groove 8 and tenon 19 be the same to be shown same distance greatly with web 1 plane and separate.

Groove 8 has the bottom of relative mitigation inclination and the top of comparatively precipitous inclination.The size of the

rib member

2,3 that engages one another can enter in the groove 8 of adjacent sheet metal by tenon 19 so that sheet material can flick.Afterwards, by the elasticity of the rolling steel that form of format roll can guarantee tenon can be in groove 8 more precipitous limit below.

Like this, when the positive edge of a wing 10 engaged with the cloudy edge of a wing 15, the tenon 19 on the cloudy edge of a wing 3 was sprung in the interface that is formed by groove 8 and is against on the sidewall of groove 8 of positive rib member, and forms the closed circuit cross section between two

rib members

2,3.

In the finished product roof system, tenon 19 can also be as the additional quick adaptive member between positive rib member that engages and

cloudy rib member

2,3 with groove 8.

And under this situation, the shape of

rib member

2,3 bottoms can also make tenon and groove play the effect of fixing device, with commonly used structure by comparison, this structure makes connector have less deflection under the load effect, and the former since bottom rib member not do not engage, like this load with regard to integrally directly be added on the sheet material assembly rather than the rib member of independent a born load on.Can also make sheet material to make now compared with this situation with thinner material.Fixing device connector is provided when not only providing additional locking mechanism can also apply load on the direction perpendicular to web plane with the disengagement that prevents positive rib structure and cloudy rib member laterally moves to prevent it.

Thereby, the invention provides a kind of covering connector that demonstrates bigger rigidity than covering connector commonly used.

The present invention has also made up the common advantage of the basic configuration with the hollow link that prevents that comparatively effectively diastrophic cold working from forming in this respect.

As shown in Figure 4, connector between two adjacent sheet metals has a kind of form of element of construction or has the general crossbeam form of two parallel edges of a wing and a planar web, the wherein top edge of a wing is the form of the hollow link of closed loop of a kind of lengthening of being inverted the triangular-section of being formed by positive rib member and

cloudy rib member

2,3 interconnection backs, the bottom flange then is the part of web 1 of the adjacent covering sheet material of veneer thickness, and the cantilever diaphragm place then is made up of the double sheet metal thickness of positive rib member and cloudy rib member bottom.Such structure member has high flexible rigidity thereby provides covering assemblies to make as a whole high flexible rigidity in each junction of composite member.

With respect to the structure of the hollow link of other shape, this structure with the hollow link of closed loop of being inverted the triangular-section has the load capacity of obvious raising.

Thereby, make the flexible rigidity that closed hollow-core construction parts have been strengthened composite member in the junction of two adjacent coverings, the structure of fixing device has further been strengthened its flexible rigidity again, and the structure of the fixing device of tenon and channel member form has also strengthened the convenient ability of assembling fast of covering.The structure of being inverted the hollow link of closed loop of triangular-section has further been strengthened the flexible rigidity of composite member.

When on perpendicular to covering assembly in-plane, applying load, for inclination is limited in can receptible deviation range in and make minimum, covering of the present invention and covering connector thereof can make it be applied to have bigger span than connection covering commonly used easily, can also reduce the risk that connector is threaded off under this load simultaneously.

In fact, we can say the effect of having played with the tubulose truss of covering integral body at the parts of the hollow link of junction.Connecting elements of the present invention provides a kind of and has become one with it and by the sheet material of its supporting and hollow-core construction parts analogous covering assembly on the flexible rigidity of lengthening, thereby has alleviated the demand that the overall span of roof system/ceiling structure is reached 3 meters to 4 meters batten building structure.That is to say, in the intensity of junction composite member as a whole owing to the effect of these hollow-core construction parts is strengthened, so also make very effectively and can adopt minimum batten, purlin or other similar support member, batten or purlin in the middle of particularly not needing when the 3-4 rice for length of span.The covering composite member only needs in its end to support.Best its end is buried in the latent groove of a C tee section passage that is supported by the stud of building unit or other frame parts again.

Thereby, the invention provides the member of attachable covering, they vertically also can be connected between covering fast with very high rigidity is laterally all being arranged.

Another advantage according to preferred embodiment of the present invention covering composite member is that the covering bottom has profile attractive in appearance, and is desirable especially when covering is used as roof system and ceiling structure.

Above just the situation of an embodiment of invention made detailed introduction, but those skilled in the art should understand, under the situation that does not exceed spirit of the present invention and scope, can do various modifications or improvement to the present invention.For example the form in the junction closed loop also can be the shape of right triangular cross-sectional, and its hypotenuse can stretch on the web of a part of adjacent covering.

In addition, web also can have one or several main enhancing rib, particularly when the required wider width of web.Main enhancing rib for example its size and profile should be suitable with the vertical member at connector place on the cross section.The formation of tenon and groove will make tenon be adjacent to groove more to move so that cloudy rib only fastens it in one direction in addition.

Tenon can replace along interval or the regular fastener that separates on the covering length with one group with another variation of channel member.This class fastener can be a clamping part, and snap-button parts or other can make each positive rib and cloudy rib bottom be maintained fixed coupled fasteners.That is to say and can adopt any suitable fastener, like this on perpendicular to the covering in-plane during applied load to prevent along moving at junction rib member on the covering length direction.

Best, fastener does not insert in the covering and goes, and also injury protection coating complete not so also can reduce as much as possible to sew and get rusty.
