Abstract

A continuous, cold rolled metal section for forming an n-sided closed frame is divided along its length by transverse aligned cuts (1, 2, 3) in longitudinally spaced pairs at its opposite sides respectively, the cuts dividing the section into the number of sides (6, 7, 8, 9) of the frame which are foldable relative to one another to form a predetermined angle of the frame, in use. The two end sides (6, 9) of the section have in their respective sides, which overlap on assembly of the frame, holes (4, 5) respectively which, when said two end sides are at the correct angle to one another in the assembled frame, are spaced linearly apart by a predetermined distance. In this way the required frame geometry can easily be achieved, assembly requiring only a simple reference tool (11; 13).

Description

Structural detail and manufacturing thereof

The present invention relates to band and it is assembled into the method for framework/framework and plate.The invention still further relates to this plate and structural framing are assembled into used three-dimensional module in commercialization and the civil buildings industry.

Steel are a kind ofly to compare the construction material with many advantages with common materials such as brick, concrete cement and timber.These advantages comprise: non-flammable; Complete recuperability; Low waste in the construction; Point-device size; Low-down maintenance cost and extraordinary heat transfer and acoustic performance.But the application of steel is not restricted owing to the producer does not also have the process technology of fully developing this potential advantage with emulative price at present.In most of the cases, particularly in building industry, steel are still quite optionally expensive at present, and it mainly is used in its described advantage than in this expensive prior occasion.

One of potential advantage of steel is to shorten the delivery cycle of a building construction, and this is because many pre-assembled work are finished outside can be at the scene.Especially preassembled degree can be according to application and difference.This comprises from internal partition (not bearing load) is provided, to being provided at carrying plate and the construction module that links together on the scene.If desired, this mould certainly can be equipped with necessary decoration and interior arrangement fully, and places as a completed unit.

This plate is become by portion's section apparatus of one group of cold-press moulding usually with module, and portion's section of these cold-press mouldings is cut into certain length and links together (as by jam weld).In order to ensure these plates is that square and size are accurate, and they assemble on anchor clamps usually, and wherein these anchor clamps make each section location before fixing.For three-dimensional module, this anchor clamps are big and complicated.

One of major limitation of this steel frame system comes from the polytropy of design.This has caused the high cost of design and all has been the input of the costliness of special anchor clamps for each new design.These expenses have hindered the use of steel in many occasions, have seriously limited its potential market.

Therefore, can obtain very big advantage from a kind of production method that can greatly reduce required assembling hardware number.

To describe a kind of manufacture method of flexibility below, it makes the manufacturing of this plate and module not re-use the anchor clamps or the orientation tool of any complexity.For any specific plate design, required unique instrument no longer is special, and this has greatly reduced by a required input of design work in-process, and eliminates the delivery time relevant with its manufacturing.In addition, this method also will show as why not use anchor clamps and this plate is interconnected, and how can be with the very high complete three-dimensional structure of inherent strength assembling.

The key of simplifying is that modern portion section rolling equipment can finish punching and portion's section can be cut into certain-length with very high accuracy and repeatability.Like this, just may with in the utilizable certain geological information adding of assembling process portion section itself.These information can be the position of total length, punching of portion's section or position of required folding recess etc.

In a preferred embodiment, can make a kind of section, making does not need further step, only utilizes an angle or linear dimension to detect just can to allow the formation of the plate with prespecified geometric.(in fact, the number of required external parameter equals N and subtracts 3, and wherein N is the limit number of polygonal frame.Therefore, for rectangular frame commonly used in the building industry, only need one with reference to dimension.)

Generally speaking, sealing rectangular frame A as shown in Figure 1 can constitute with four independent part sections that are cut into certain-length.Each section all is inserted in the anchor clamps, and these anchor clamps are suitable for the particular design of plate to be produced.In when location, these sections are clamped in placely can to link together the end of these sections (welding, riveted joint).The effect of anchor clamps is to guarantee: 1) each section is located relative to one another to form the correct effective dimensions of framework, with 2) these sections contact with correct angle.

We know if having each section of precise length can accurately locate each other to form the pivot joint rectangular frame of a sealing, so only need to determine that an angle just can form the framework with accurate geometry shape.The invention describes and a kind ofly form the method for this framework in this mode, it has greatly simplified the process of building framework.This makes it possible to utilize modern portion section rolling equipment very accurately to cut punching in the operation of rolling.Therefore, in the process of rolling section, it is possible can embedding required whole necessary geological information of framework of formation with above-mentioned method.

These geological informations have two kinds of citation forms.At first, each continuous relative the other side of portion's section is accurately located, so that the linear dimension of framework is correct.The end of two planar portions sections linked together be not enough to accurately, firmly form the framework of required precision.

Provide the method for two kinds of location adjacent section below.First method is to make otch to the portion section, makes continuous portion's section with a joint connection that plays a part corresponding to the hinge on the summit of framework.The advantage of this method is that four continuous sections can be folded into a parallelogram with known circumferential length (like this, need wait to limit with the framework that forms a rectangle openend right angle) apace.A shortcoming of this method is that bigger framework is difficult to make the length of portion's section to equal the girth of framework.Second shortcoming is if the wider width of otch, articulate (thereby, framework) be coarse.The 3rd shortcoming is that for closed frame openend still needs some devices of accurately locating.

Second method is in the accurately punching of end near each single discrete section, makes these holes overlapping pinpoint the time.The advantage of this method is that each several part can be used for easily constructing big plate.The method in the hole that its shortcoming is need to use some pins to pass each corner connects to allow this parallelogram to next step of fixed angle.

Can form an accurate angle in two ways.At first be to use an angle template or anchor clamps.Next is if datum mark forms at distance corner known distance place, sets diagonal distance utilization between these datum marks so and colludes a strand law and determine angle.Use the shortcoming of template or anchor clamps need to be a big instrument to form an angle accurately.The advantage that femoral triangle shape is colluded in utilization is that datum mark can be the form in point-device hole of going out on portion's section in the operation of rolling.By moving this framework (its hole around joint or pin joint articulates), when matching with these holes, the linear tool of a known dimensions just can obtain a correct angle.Any error on the size of benchmark instrument all will become the error of drift angle.Degree of closeness between this sum of errors datum hole and drift angle is inversely proportional to.

The first method of location adjacent section is presented among Fig. 2, the continuous cold rolling portion section that one of them is single, and preferably metal has the length (having the small adjustment of stretching, extension possibility that is used for follow-up BENDING PROCESS) of the girth of the framework that equals to expect.The Duan Weisan of this bending in it to be formed leaves deposit and by being positioned at the relative both sides of slot part and extending to the paired

otch

1,2 and 3 of base portion.At least two reference positions are formed on the form in

hole

4,5 on the side of

section

6,7,8,9 separately, in addition on two

petiolarea ends

6 and 9 the side, rather than two adjacent sections.Utilize modern portion section rolling equipment, these otch and datum hole can very accurately be located.Therefore,, only need this section of bending as shown in Figure 3, make two datum marks separate with a certain absolute distance 10 in order to obtain required geometry.This can utilize, and the simplest reference tool 11 guarantees among Fig. 4, and this reference tool 11 has the pin 12 that separates with preset distance, and when section 6 during with 9 one-tenth 90 °, these two pins 12 are configured in the hole 4,5.Another kind of reference tool 13 can comprise angle and linear information, and as shown in Figure 5, it is used for the right angle corner of a framework.Certainly for other angles by instrument 11 or 13 settings, distance 10 no longer is by instrument and two hypotenuses that the leg of frame limits, and only is the 3rd limit.

The position of

datum hole

4,5 on portion's section can be a function of framework girth, no matter make which type of design, the final distance 10 that ask in these two holes all is constant.This can all use same linear reference instrument 11 in all plate designs, thereby has shortened newly-designed

delivery cycle.As hole

4 and 5, preferably form in (cold) operation of rolling with band formation portion's section or section (side), but this not necessarily in these reference positions, also can form in follow-up step.

Can change otch and be positioned at the design of bending part between section to hold many different interconnection techniques, portion's section shape and material thickness.The simplest design is the portion's section with flute profile or U-shaped cross section, cuts out otch at the either side of base portion, as shown in Figure 2.The size of otch should conscientiously be selected.If otch is too wide, then the position of bending is just indeterminate, but also will lose accuracy.If otch is too narrow, then bending is too tight, makes the groove side pile up, and can not obtain 90 ° turning.Also can design more satisfied otch.For example, the core of otch can be narrower with allow closely, accurate bending, and otch 14a can be angled in the zone of a side (Fig. 6), connects 14b to allow inclined-plane shown in Figure 7.This means that it is concordant connecting the surface, can provide good connection for various the application widely.But most of interconnection techniques need each section that certain lap is arranged, so the design of otch will be considered portion's section that material will form.For simple channel-shaped portion section, do not need to carry out any deposit and just can make folding the generation.But, if portion's section be " C " shape portion's section and have turned-back edge 15 (it has bigger load bearing capacity) in the groove both sides, then need to carry out the deposit shown in Fig. 8-10, the turned-back edge collision can not take place and carry out bending with permission portion section.

Can also be possible by the pressing lap line or along wanting the folded portions perforation to be beneficial to accurately also simple folding part section.But must be noted that, can not weaken this section, this will make the processing that forms the preceding element of a framework become difficult.

Influence the application of sheet material on plate for fear of the overlapping region that bending is turned, can make these zones 16 crooked so that they can be concordant with 12 as Figure 11.This can carry out on production line, also can carry out in an independent extrusion operation.

In the overlapping region of portion's section, can go out identical hole 17, when each section was bent into right angle (perhaps last section is exactly to straight), these holes were overlapping, shown in Figure 13 and 14.Except two overlapping holes, also can use the point of two printings or the hole of aiming at the point of a printing.So various suitable alignment devices can use.Have the plurality of optional method to fix the overlapping region, this selection depend on concrete application, required speed, expense and at the scene assembling still in factory-assembled.Possible interconnection technique comprises that welding (as the butt welding of mitered or the spot welding of lap), riveted joint are connected with the nail formula.In order to ensure the accuracy of maximum, the head of fastening means can conversion, makes in case one or more alignment pins that are positioned on the instrument pass two overlapping Kong Caike connects, and has also guaranteed the accuracy of single connection in addition.This tool assembly is extensible to make the function of reference that has linear and angle on its structure.When this assembly is used for connection procedure, record can be kept to an operation with being connected.Under an opposite extreme situations, the

hole

4 and 5 at interval linearly among Fig. 4 and Fig. 5 can be positioned to make this to be spaced apart zero, and the reference with same form shown in Figure 13 and 14 then is provided.Like this, in fact, reference tool is the hole that rather than two pins pass two alignings.For the rectangular frame of A for example, its reference position, promptly the otch that the

hole

4,5 on two adjacent section can be common with it makes distance 10 become the diagonal of framework fully at interval.Thereby

hole

4,5 and different hole 17 overlap, and can replace them like this, for both are on active service with the location division section and form an accurate angle.

In general, the distance 10 that datum hole is 4,5 is big more, and attainable accuracy is high more.If should distance 10 be reduced to zero, the hole is overlapping shown in Figure 13 and 14, still might obtain desired geometry and without any need for reference tool.But the shortcoming of saving witness mark fully is to exist and loses accuracy, this be because, compare than the same error in the restricted publication of international news and commentary entitled distance with one, above-mentioned overlapping little error will cause the out-of-proportion error on the expected angle.Therefore, when assembling frame, can adopt the

hole

4,5 of linear interval and the hole of aiming at 17.

Use the combination of automatic interconnection technique and auxiliary angle or linear reference, might use fully independently portion's section rather than the notion of this construction framework of folding band continuously.If need portion's section of dissimilar frameworks to be formed in using, this is very useful.But if remove arbitrary detent mechanism, material must be formed to reduce the free degree of system by a continuous band so.It should be noted that

linear datum hole

4,5 preferably is positioned at the both ends section, unless have with the hole of closed-loop overlapping (other setting).Otherwise last link position is uncertain.Use overlapping hole to allow to become the reference dimension of plate leading diagonal in sealing connects, giving has great accuracy.

The notion of utilizing known datum mark to locate the adjacent sections of same framework can be extended to interconnecting that adjacent frame asks.One group of single framework can be joined together to form bigger framework shown in Figure 15 or more complicated three-dimensional module as shown in figure 17.Bigger framework can utilize said method to make, but adopt many have than small frame be easy to handle and design flexible advantage, that is to say that the wide variation of big frame design can utilize simple less standard card cage storehouse to obtain.

Usually, big frame and module itself needs big and complicated anchor clamps to be used for accurate installation.But, the branch framework in 18 holes, known accurate benchmark position (with screw or automatically locating pin, welding etc.) and element are arranged in order to the location by utilization, can not use any anchor clamps just can make up big and complicated structure fully.For example, by aiming at the punching of known location, plate or framework can be adjacent portion's section and extremely accurately locate, shown in Figure 16 a and 16b.This means in the building site and can lower specification requirement, and a large amount of plates and framework can be assembled into module easily.

This plate or frame set are dressed up modular form and are allowed more structure to carry out in the controling environment an of production equipment, rather than carry out in the building site.This means and shortened the delivery time, improved product quality.

The simplest method is to use many identical wallboard spares or framework, is connected with the ceiling plate with suitable base plate plate, as shown in figure 17.In this design, there is potential bad load to shift between adjacent plate or the

framework

19,20 to stop the module distortion.This is a potential restriction in the design, because the distortion in the transport process between factory and scene can damage outside and inner configuration.

An improvement of this basic conception be to guarantee the plate on end face and ground or framework not with the plate or the frame alignment of wall, as shown in figure 18.This overlapping providing than the better structural intergrity of the design of front, because the effect of tiing a knot has been played in the end of each plate between the section of two plates, these two sections are connected in the end of this plate.Therefore, this prevents to twist plate.

But any given module both can make up (thereby, need be used for the anchor clamps of plate and these plates are assembled into the anchor clamps of module) by the conventional method of utilizing single section, or also can utilize to make and divide the embedded method of geometry of plate to make up.In fact, can further extend the assembling of the three-dimensional module that do not need to be beneficial to three-dimensional grips without the constructing technology of anchor clamps.By using reference opening or otch and the standard of facing that is connected plate, shown in Figure 16 a and 16b, guaranteed the accuracy of its position.If particularly use a mating holes and the instrument that is connected simultaneously, assembling process can be simplified more again.

Porose, otch, position folding and cutting can be the predefined function of whole module (or only being plate) size.To utilize as block length, highly, floor load (with the degree of depth of board section definitely) and horizontal Center Gap input parameters such as (, reducing the vertically distance between support) and the single design principle formulism that automatically produces all manufacturing parameters is possible in order to increase the stacking height of module.Thereby reduced the workload of required detailed design; Also reduced cost and delivery cycle in addition.

Another is extreme, greatly makes assembling process lower specification requirement owing to have, and it is possible that the module for the treatment of the complete form of assembling at the scene is provided.This complete form provides the portion's section that can assemble the composition plate easily and fast ready-madely and be assembled into the punching press in advance of module subsequently.One of restriction that portion's section is rolling is that often required than some the weak point portion section in the plate length of the minimum length of a cutting part section is long.Usually, manually cutting into shorter length by the length with standard portion section, to obtain the plate assembly be possible.This process is labor intensive and be easy to make mistakes very.But, in portion's section, insert accurate otch, it is possible making this section be separated into the length with preliminary dimension.Therefore, whole band has the length that is suitable for automatic cutting, but each section of portion's section can be cut off easily to form one group of single short section.Each section all dashes forming all essential geometry location holes of framework of expectation apace.If essential, mark in the operation of rolling, for each section, make each section after cutting off, have and can debate other production numbering, orientation etc.

Transport by this way, effectively supply can assemble fast in a large number as being useful module under disaster relief situation.The existing continuous portion section that is used to be folded into framework can be transported with little space, and the existing strip sections that is used to be cut into shorter length has also reduced the danger of losing or damaging to element.

Another complete form can be that advantageous embodiments is in the roof trusses supply side.A large amount of frameworks can portion's section form be placed on the rear portion of truck and keep flat packing on-the-spot folding and fixing to be used for.No matter be the simple spandrel frame 21a shown in Figure 19, or the double triangle framework 21b shown in Figure 20 with a middle part supporting strut, can suppose that predetermined articulated position just is enough to limit this geometry assembling by a single continuous portion section without reference tool.

Another example by the non-tetragonal framework that continuous portion section is made is a pentagon framework, and it is used for the assembling such as the small-scale structure in greenhouse etc., as shown in figure 21.Yet, need two reference dimensions as 22 and 23 to guarantee correct geometry.Use the asymmetric framework of the supply inclined roof panels as shown in figure 22 of four portion's sections, can only be had the similar results of a reference 24.

An asymmetric framework can embody the intrinsic advantage of this notion.Only data need be imported the computer of the rolling grinding machine of control part section (it can be that a whole automatic sales order process part is further to make other process streaming) in order to make the plate that has the minor variations size in a large number.The result is easily to hold complicated structure (as the top board that tilts gradually).

As mentioned above, this notion is used for single portion's section form, or for being easy to final assembling, it all is possible also can being used to utilize the band of a contiguous segmentation.With the combination of elements shown in Figure 23 and 24 also is possible, here, and the core heart that the band 25 of a contiguous segmentation connects as a grid beams structure together with two outer segments 26,27.In this embodiment, the hole of going out on the hole 28 that makes the segmentation band, the position that calculate the hole and single the section 29 is relevant.

Although metal is the preferred material in the said method, wooden section/portion's section also can be used as the knot parts.

How the computer-controlled program that utilizes modern portion section rolling equipment described above does not need change instrument and hardware to make the framework and the plate of wide region easily by changing software domain.Propose a kind of method, thereby the geological information that embeds the external reference framework traditionally is actually in manufacture process through engineering approaches in product itself.Therefore, the manufacturing expense of this product and corresponding delivery time reduce significantly.

Therefore, being used in colding pressing in framework and the plate structure, to form section be to be rolled into by the portion's section with intrinsic geometry relevant with the predetermined geometry of finally framework or plate.These sections usually can only form a framework with a dimension reference value (angle or linear value), and do not need outside anchor clamps or jig, just can form an accurate element.Like this, a large amount of different products can be made fast and accurately and not need complicated expensive hardware or fabrication tool.This section can form with complete form supplies with on-the-spot plate, or can not need anchor clamps just accurately to be assembled into module, and if desired, this module can be transported preceding assembling at the scene.
