Description
Invention field
The present invention relates to have the no welded linkage of moment of resistance performance, described device is used to use cancellated architectural design, engineering, manufacturing and the field erected all spectra of pipe member.
Background of invention
Net structure is generally by two kinds of basic building blocks, and the network of node and bar shaped connector constitutes.When strip member is made of cylindrical tube because the layout of bindiny mechanism, with being connected of node generally be that pin connects.Adopt the device of the continuous network that pin connects to be generally used for designing, engineering, manufacturing and numerous cancellated installation, comprise the application of dome, facade, tower, coliseum top, bridge and various truss, but be not limited to this.
Generally speaking, typical pin connection device adopts the spherical nodal that is connected with a plurality of tubular frameworks usually.Node has the part that holds coupling assembling such as the opening of bolt, and the end of tubular framework is welded on other part such as cone end face of coupling assembling.The end of tubular framework can be connecting so that simplify or strengthen of taper.By each spherical nodal being connected with a plurality of tubular frameworks, just can connect to the network of a large amount of nodes and framework mutually, thereby form various net structures with coupling assembling.The modification of many this common " pipe and spherical nodal devices " adopts the node that is connected with the plane coupling assembling, and the direct and coupling assembling of tubular framework welds.
A kind of pipe of specific type and spherical nodal device have adopted the spherical nodal that has a plurality of circular ports, and bolt or pin insert in this hole and be fixing therein.The infundibulate lining of the cylindrical base of concrete hollow is arranged between the cylindrical framework of spherical nodal and hollow.The end of framework die forging one-tenth rightly is consistent with the funnel shaped at lining top.The end of framework die forging is in the same place with the lining welded top.Bolt inserts in the framework, and stretches out from the lining pedestal, is connected and fixed by being threaded onto on the node.Be fixed to outer T-Ring on the bolt rotatably and be used for turnbuckle.In this way, each framework is connected with spherical nodal separately, thereby forms net structure.In these layouts, bolt has produced shearing force, tension force and pressure.In some cases, rim bearing is stressed.Usually bolt can bear tension force well, and just bearing of shearing force and pressure becomes problem.
The continuous network of pin connection device can be used for net structure in every way.The scope of using is from being additional to the aesthetic design of facade at first to conduct as bearing structure.The use of network structure indicates determines which type of pressure and tension force can act on device.Network design is become can bear the value that calculates on the direction of pressure and tension force.Effective design of this network need be developed the appropriate model of the pin connection device that is used for structure design.Preferably, model is simple as far as possible, but does not reduce the accuracy of manufacture.And when using cylindrical framework, the linkage of use should be optimized common pressure-bearing characteristic to pipe as far as possible.
There are some defectives in typical pipe and spherical nodal device, and these defectives become clearly in design, manufacturing and cancellated on-the-spot the installation.The tie point of each the member-node in the pipe of standard and the spherical nodal device all is fixed to by the hinge that is positioned at node usually, is represented as the elastic component and the three-piece device formed of pipe of the weak point of bolt.Because framework is often wedged and is welded on the infundibulate lining, and and then is connected with node, the three-piece type need be measured the moment of member-node tie point accurately.The three-piece type must obtain accuracy by the short elastic component and the combination of hinge.Because caused the complexity of net structure design, so the three-piece type is problematic.
Use the tie point of better simply pattern claimed structure between framework and node and have moment of resistance performance in fact, thereby can cancel the elastic component and/or the with gemel ring of the weak point of representing bolt.Yet because the wedging of present designing requirement framework lining, ring and bolt, pipe can not bear moment fully with the spherical nodal device in this is connected.Other hinge-type structure part has been introduced in the design that is reduced to of the framework cross sectional area of junction, has prevented the transmission of tie point moment especially.Like this, under the situation of carrying, pin connects fine rotation.And short elastic component does not just have the moment transmission.This has also prevented from load is put on the framework, therefore, loudspeaker, lamp assembly and other device must be connected on the node.And, when using cylindrical member, the cross sectional area of junction reduce to have reduced its pressure-bearing characteristic.
For being actually used in structure design, the element of linkage should be easy to make relatively.In pipe and spherical nodal device, it is often restricted to be difficult to manufacturing spherical nodal and size.Pipe and spherical nodal device are also restricted to the material type that can use.Though polymer, plastics, aluminium and multiple synthetic may have the desirable necessary strength of the net structure of being used for, cost and aesthetic design characteristic, these materials are not easy to welding usually.In cancellated manufacturing, use welding cost high and consuming time.It needs quality control method, uses raw material and needs the experienced operator.In pipe and spherical nodal device, use welding to reduce the permissible stress that some material can bear, and in special use, can not pay attention to.
At last, because many cancellated complex characteristics, install at the scene and assembling is all very difficult and expense is high.The installation process of these structures is very strict, and cancellated installation is often carried out like this, promptly, the a series of assemblings of two nodes that are not connected with framework as yet by in advance connect to firmly fix and put in place, like this, between two nodes that are fixed, connect framework and need remove node by force with tube connector.This is just very consuming time and can damage structure.
Like this, just wishing has a kind of linkage, and it can be fixed to the elongate articles that is fastenedly connected with node simply, and need not hinge and/or short elastic component carry out the transmission of the power at tie point place.A kind of linkage is developed in same hope, and its allows to use cylindrical member, and need not significantly reduce its cross sectional area at the tie point place.And wishing has a kind of linkage, and it does not need to be welded to connect framework and node, and between the node prepsetting gap is being arranged so that insert framework between two fixed points.There is also a desire for a kind of linkage design, wherein Zhuan Zhi element is easy to make, and the type of Available Material is wider, and shape is not limit.Also wish to avoid the shearing force and the pressure of bearing bolt in addition.

Detailed Description Of The Invention
As shown in Figure 1, the spherical net structure 9 that is placed on the base 10 uses at least one co-axial joint system 11 as shown in Figures 2 and 3.The preferred embodiment of the co-axial joint system 11 that has assembled comprises a plurality of co-axial joint system connectors 12.Each connector 12 all is made of the coupling assembling 16 of three-dimensional locking connector 14, framework 15 and framework-locking connector.In fact, framework 15 is connected on the locking connector 14 by the coupling assembling 16 of member-locking connector, and locking connector 14 plays the node effect.
With reference to Fig. 4, the coupling assembling 16 of the framework-locking connector that uses in co-axial joint system has used has framework 15 to insert wherein gland 18, can connect the end cap 19 of framework 15 and gland 18 and end cap 19 is fixed to whole bindiny mechanisms of 20 that are labeled as of locking connector 14.End cap and gland comprise inside and outside connector respectively half, and tension force is carried and the gland bearing pressure in bindiny mechanism.End cap is free to slide in bindiny mechanism, and framework, end cap, gland and bindiny mechanism form coaxial layout.
Present embodiment has external diameter (O.D.) or has attacked externally threaded framework connector.End cap 19 is cup-shaped column, and there is perforate 22 its bottom, and to hold bindiny mechanism 20, bindiny mechanism 20 is preferably turnbuckle.End cap 19 has the inner chamber 23 that leads to the end cap open top.Turnbuckle inserts the inner chamber and the perforate in the end cap base 22 of end cap, and is screwed in the locking connector with the predetermined degree of depth.Like this, end cap just is limited on its depth location that can take out from locking connector.Pulling force buttless thread 34 is positioned at the inner surface of end cap and pressure buttless thread 36 is positioned at the external surface of end cap.Two groups of screw threads are all extending with being connected on the vertical direction in surface of locking connector.
End cap can be connected with locking connector at the scene or in the factory.Because can avoid assembling bolt at the construction field (site) fully, thus preferably connect end cap in factory, thus reduced the time at the construction field (site).In addition, turnbuckle can desired depth be arranged in the locking connector to simplify the size Control of this structure.
The pedestal 24 of end cap be arranged in parallel with locking connector and can evenly be arranged on flat being connected on the surface 28 of locking connector ream, or can move along turnbuckle, till the packing ring 30 that touches on the turnbuckle that is arranged between bolt head 32 and the end cap base.Like this, just having limited end cap can be from node, i.e. the distance removed of locking connector.Connect the circular shrinkage hole that surface 28 comprises that locking connector is interior.Being designed and sized to of shrinkage pool diameter can be held the gland external diameter.Like this, the connection between locking connector shrinkage pool and the gland has just produced shearing force.
The cylindrical framework 15 that has near-end and far-end with respect to locking connector can be connected with the surface of internal cavity of end cap.Framework has saw-tooth thread 40, and saw-tooth thread 40 is positioned on the external surface of its at least one end, thereby has formed terminal coupling part.Pulling force buttless thread 34 complementations on screw thread 40 and the end cap inner surface.Like this, produced tensioning load by turnbuckle, end cap and framework.The tension force path is from the locking connector to the turnbuckle, from turnbuckle through being pressed in packing ring between turnbuckle and the end cap to end cap, then from end cap by being threaded 34,40 to framework between end cap and the framework.The pulling force buttless thread provides very little pressure support relatively.And because end cap is free to slide to locking connector on bolt, bolt can not bearing pressure.
Therefore, the cylindrical gland 18 of hollow just is provided.Gland has enough big diameter to hold cylindrical framework and end cap.Gland is as length adjustment piece work, and the active length that its allows framework is greater than its physical length and can slide with respect to framework.Can both enter the inner chamber of gland from top that lining is opened and the bottom of opening.The inner surface of gland 18 have with the end cap external surface on the buttless thread 38 of pressure buttless thread 36 complementations.End cap plays the gland between fastening framework and the locking connector.Like this, produced pressure loading by gland, end cap and framework.Pressure-path is from the locking connector to the gland, is threaded onto end cap from gland between gland and end cap, and the framework end of placing through end cap annular shoulder 44 from end cap 42 is to framework then.So shoulder has formed the thrust bearing of exerting pressure.
Strengthen the pressure buttless thread in case the not-go-end lid is pressed into gland.Hold out against the supporting that connection does not provide tensioning load between gland and the locking connector.Yet, whole coupling assembling provides and the engaging fully of tension force, pressure and shearing force, these power are produced by the element that can bear each power best, and since framework with there not being swedged coupling assembling to be connected on the locking connector, moment of resistance connection has just produced.
To Fig. 8, the pedestal 24 that the embodiment of the external diameter framework of co-axial joint system passes end cap 19 by the turnbuckle 20 that will be equipped with packing ring 30 tightens in the locking connector 14 and assembles, and movably end cap is connected on the locking connector with reference to Fig. 5.Then, cylindrical framework 15 is inserted cylindrical gland, and framework is location like this, that is, aligns with end cap between two locking connectors at the screw thread on the framework outer face.Therefore, framework, gland, end cap and turnbuckle are coaxial.The length of framework leaves gap 46 between the turnbuckle of framework and every end, to be convenient to inserting framework between two locking connectors.
The remainder of an assembly only end of the frame of reference is illustrated.End cap moves to framework with packing ring in the inner chamber of end cap and part turnbuckle, shown in arrow among Fig. 8 48.Buttless thread on the end cap inner surface is screwed into the buttless thread on the cylindrical framework external surface and tightens, the shoulder 44 of being close to end cap up to the end 42 of framework, at this place, packing ring 30 should and constitute good bond between the pedestal end face of end cap 19 of inner chamber 23 bottoms at bolt head 32.In Fig. 2 to 8 and device shown in Figure 9, each turnbuckle 20 can not have screw thread and is not round preferably in the bar portion of contiguous its head 32, for example is the hexagon that can make turnbuckle engage and rotate with spanner.Like this, turnbuckle can be loaded on locking connector earlier, and bolt head is enough far away apart from locking connector, can move along turnbuckle to guarantee end cap, reaches docking of desirable its shoulder 42 and framework 15 ends.Be present between bolt head and the packing ring 30 on the one hand, be present in any gap of end cap recess pedestal or loosening on the other hand, can both eliminate by bolt is pulled in the locking connector, the described packing ring 30 desirable fluid-tight engagement of having set up between bolt head and the end cap of pulling, and prestretched bolt if desired.
Then, gland 18 moves to end cap along framework, and the buttless thread on the cylindrical gland inner surface is screwed onto on the buttless thread on the end cap external surface and tightens, so that the surface 28 of locking connector is close in the lower end of gland 18.In case this is linked and packed, this connection can be fixing by dog screw 21, and dog screw 21 is contact end cap screw thread closely.
The length of framework is determined by structure Design constraints.Yet, in case designated length, just must be with very little fit tolerance manufacturing to guarantee and the correct assembling of end cap and the good alignment of gland far-end 50 and end cap.
Can enough long handle spanners with end cap pull into being threaded of framework, and with gland pull into end cap be connected and with the docking of locking connector surface 28.The long handle spanner has the elongated handle at band bending top and the projection of extending to handle from top end.According to embodiment, gland, end cap and framework have opening 45 (Fig. 2) to hold the projection of long handle spanner.In the connector 12 of well assembling, end cap shoulder 44 engages framework end 42, packing ring 30 is fixed between bolt head 32 and the end cap 19, being close to surface 28 the level of being adjacent to gland is fully, and these group members have all kept being in contact with one another in whole thermal expansion that coupling assembling will stand and contraction scope.Shown in locking connector 14 be hexagon, but in fact be not limited to this shape, and when being used for space frame and other similar structures, can be three-dimensional.Locking connector should be designed to be able to hold a plurality of frameworks that must be attached thereto.Except that this design was considered, locking connector itself can be a virtually any size, shape or configuration.If to the specific requirement of spherical nodal, co-axial joint system can not be more suitable for being used for space frame and make more efficiently.Similarly, framework is preferably strip and columniform, but in fact in the co-axial joint system framework do not rotate.So framework is not limited to the sort of shape.Framework can be virtually any size, shape or configuration, comprises pipe crooked or distortion and the prismatic pipe that forms octagonal cross-section, as long as the framework end can be connected with cylindrical end cap.Therefore the coupling assembling of special framework-locking connector is connected framework with locking connector, and need not handle or rotate framework, allows to adopt non-cylindrical, non-strip, or or even twines the framework of shape.
Because co-axial joint system is made up of the element that links together at rigidity (stiffness) node, so co-axial joint system has many good qualities.The elimination of taper connection point allows the moment of torsion transmission, and disappears except when during net structure that the model manufacturing has proposed, require to use the hinge of hypothesis, thus the simplified structure design.The moment of resistance performance of co-axial joint system also allows co-axial joint system to use in flexible frame and triangular truss.And framework can be handled as beam.Like this, load can be added on the framework, no matter so loudspeaker, lamp and miscellaneous equipment can be connected to node.Still on the position of the most convenient of framework.
Because co-axial joint system adopts the framework that directly is connected with locking connector in moment of resistance set mode, therefore so co-axial joint system can utilize the load performance of cylindrical framework more, and the supporting capacity of device is increased to the twice of the pipe and the spherical nodal device of standard.Therefore, co-axial joint system can adopt or the pipe of a semidiameter or double length, but still can keep the supporting capacity identical with the spherical nodal device with the pipe of similar size and carrying.
By having eliminated the necessity with framework and coupling assembling welding, co-axial joint system also makes is all having very wide scope on the selection type and on the site assembly of structure.Various material with weldability difference of ideal tensile strength, price, aesthetic requirement and other characteristic all can be used for co-axial joint system and the destruction to material that needn't worry to cause because of welding, and reduces their supporting capacity thus.The cancellation welding can also reach quick assembling, reduce cost, reduces procedure of processing and material consumption, and can make the site assembly of structure more flexible., just no longer be problem particularly so between two fixing locking connectors, insert framework because co-axial joint system provides prepsetting gap for framework.Different with the spherical nodal device with some pipe, co-axial joint system can make the installation of two frameworks between the fixing node or replacing become and be easy to.Because gland has compensated some length between two locking connectors, and gland is overlapping with framework fully before connecting, so this possibility is arranged.
Almost any solid material all can be used for co-axial joint system.The material of weld strength properties difference need not weld during particularly because of the co-axial joint system assembling, so all can adopt as aluminium or composite material, and needn't worry to reduce the strength of materials, ductility or other performance.
Second embodiment with co-axial joint system that framework internal diameter (internal thread) connects is shown in Figure 9, has wherein provided the corresponding label of suffix A that adds to show difference with the element components identical that has illustrated.End cap 19A fixes by full thread double-screw bolt 80, two locking nuts 82 and packing ring 30A and locking connector 14A.The maximum spacing that this layout allows end cap to be left locking connector carries out scene adjustment, thereby obtains the desired fastening assembling of framework between two locking connectors.
End cap is columniform, and has inner chamber that can lead to the end cap open top and the internal diameter that is preferably steady state value on the height of whole inner chamber.End cap excircle dimension difference, the cylindrical at end cap top 52 is less than the cylindrical of end cap bottom 54.The top has external broach buttless thread 34A, and with the interior buttless thread 40A threads engage of framework 15A, and the bottom has external pressure buttless thread 36A, with the interior buttless thread 38A threads engage on the gland 18A.The framework that can be connected with the externally threaded top 52 of having of end cap has buttless thread 40A being positioned at its terminal inner surface.The pedestal of end cap also is parallel to the connection surface 28A of locking connector, and can evenly be placed on the connection surface of locking connector.The tensioning double-screw bolt passes the pedestal of end cap and stretches in the body of locking connector.In fact locking nut 82 and end cap base 24A are separated by packing ring 30A.Like this, the tensioning double-screw bolt has been screwed into locking connector.
Hollow cylindrical gland 18A has enough big diameter to comprise cylindrical framework 15A and end cap 19A.Gland is as length adjustment piece work, and can slide with respect to framework.Can enter the inner chamber of cylindrical gland from top that lining is opened and the bottom of opening.The surface of internal cavity of gland be with the end cap bottom outer surface on the buttless thread 38A of buttless thread 36A complementation.End cap plays the gland between fastening framework and the locking connector.Like this, gland between end cap and locking connector 14A, play a part prevention from or put on the moment of framework.
The embodiment of this co-axial joint system internal thread framework is similar to previous embodiment, be to assemble like this, that is, the tensioning double-screw bolt that is equipped with packing ring and locking nut is passed end cap base be screwed into locking connector, and movably end cap is connected on the locking connector.Then, framework inserts cylindrical gland, and framework is such location, that is, the screw thread that is positioned on the framework inner face aligns with end cap.The part tensioning double-screw bolt of end cap in packing ring and end cap inner chamber moves to framework.Buttless thread on the end cap outer surface of cupular part is screwed on the buttless thread of cylindrical framework inner surface, and tightens with for example long handle spanner.The outer shoulder 42A that framework lower end 44A clip end covers, and packing ring 30A is close between end cap base and the locking nut.Then, the buttless thread on the cylindrical gland inner surface is screwed on the buttless thread on the end cap bottom outer surface, and tightens with for example long handle spanner, thereby makes the gland lower end be close to locking connector surface 28A.
Be used for framework is connected to end cap and gland is connected to the commutative hand of spiral of buttless thread of the complementation on the end cap, so that be easier to assembling.By the exchange hand of spiral, for example, the operator can be screwed to end cap on the framework, next gland is screwed on the end cap and need not turns original being threaded between end cap and the framework.Hand of spiral both can be also can be counterclockwise clockwise, as long as they at two tie points, exchange between end cap and framework and end cap and the gland.In addition, though present embodiment has adopted complementary saw-tooth thread to be connected the method for optimizing that is connected with end cap with gland with end cap as framework, other method of attachment also can be used for co-axial joint system, comprises welding, although it is out of favour.
In an alternate embodiment, as shown in figure 10, turnbuckle 60 is axial hollow, and has the central passage 64 of opening 62 to allow rope W to pass bolt.In addition, as previously mentioned, the shape of locking connector and layout are not limited to this pass and execute the shape shown in the example.Locking connector can be an Any shape, as long as this shape can make framework-locking connector assembly 16 securely framework 15 is close to locking connector 14 location.In another alternate embodiment shown in Figure 11 and Figure 11 A, locking connector 70 also is a hollow, and each opening 72 that connects on the surface 74 leads to center cavity 76 to be suitable for using rope in net structure.Locking connector also has a window 78 so that rope penetrates.
Although the framework of having described has inner chamber, it also can have the packed space of different range, and needn't be hollow basically.The volume filling extent of framework depends on desired supporting capacity and other design consideration.
Though the embodiment of shown co-axial joint system generally adopts turnbuckle that end cap is connected with locking connector, yet must know, co-axial joint system also can adopt other linkage, as the full thread double-screw bolt.
And co-axial joint system can be furnished with threaded sleeve pipe, and as shown in figure 12, described sleeve pipe is used to connect the pipe of different-diameter.Sleeve pipe 79 allows the tubular framework 80 of different size and identical locking connector connection.
In addition, according to locking connector 14A, ream plano-concave mouth 28A, gland 18A, the intrinsic design flexibility of end cap 24A, device size can be designed to connect the tubular framework 80 of various different-diameters on identical node, and need not use sleeve pipe 79.
