Abstract
The invention relates to a frangible connector for clamping two plates together. The connector comprises a distal flange (4); a proximal flange (2); and a shaft (3) between the flanges (2, 4). In use, the connector is inserted into slots (S) in the plates in a first orientation until the distal flange (4) passes fully through the slots (S). The connector is rotatable to a second orientation in which the plates are clamped between the flanges (2, 4). The shaft (3) has deformable portions so that, as the connector is rotated, the deformable portions deform until it reaches the second orientation. Part of the connector is frangible so that, when subjected a load above a threshold value, the connector fails such that the clamping force between the flanges is lost.
Description
Technical field
The present invention relates to a kind of frangible link that two plates are clamped together of being used for.
Background technique
The present invention is directed against the design of the mating system of concrete floor.Yet the present invention can be applicable to following situation widely, that is, need two plates be clamped together Face to face temporarily, need under the load perpendicular to the plate face, make them away from each other then.
A kind of such mating system is known as disclosed Peikko TERA joining portion in EP-A-1123443.
This joining portion is used for the floor such as buildings such as warehouse and supermarkets.The floor is made up of many concrete slabs of cast in position.The joining portion defines the space of cast concrete in it.Each joining portion is provided with a pair of edge guide to each contiguous concrete slab, and each edge guide has a plurality of anchor portion in the concrete that is fixed to each side of joining portion.Along with concrete sclerosis, concrete shrinkage, and each guide rail drawn back each other, thus provide edge-protected for concrete.In transportation and casting process, it is aligned together that each guide rail must keep, and guarantee their easy operatings, but along with concrete shrinkage, they also must be able to separate.
For each guide rail is kept together, frangible bolt (for example, the frangible bolt of nylon) is used to connect each guide rail.Each bolt is fixed by nut and is surrounded by split sleeve, thereby for nylon bolt provides extra rigidity, and in transportation and installation process, keep correct alignment.For example, this configuration is disclosed in EP1867783.
Each link comprises three independent parts.For a link is installed, at first each plate is kept alignment, make respective connecting align.With the position that it is suitable that sleeve is beated in, then bolt is passed the hole and pull out, again nut is placed on the threaded end of bolt.Begin to use the electric screw driver tightening nut then with the finger tightening nut.This process repeats repeatedly along the length of guide rail.
Summary of the invention
The present invention provides a kind of manufacturing and more simple link is installed.
According to the present invention, a kind of frangible link that two plates are clamped together of being used for is provided, each plate has the slit of alignment, and said slit has extended configuration, and said link comprises:
The far-end and the near-end that separate along axis;
Be positioned at the engagement head of said near-end;
Far-end towards said far-end keeps flange;
The near-end terminal at said engagement head keeps flange; With
Bar portion between said distal end flange and proximal rim;
In use; Said link can be inserted in the slit of alignment of each plate along first orientation; Pass completely through said slit up to said distal end flange, and said link can be around said rotational to second orientation, in use; When second orientation, each plate is clamped between said distal end flange and the proximal rim;
The cross section of said bar portion has the shape of elongation, and in use, the longest dimension of said bar portion is corresponding with the shortest size of said slit; And but said bar portion has deflector; Make that in use along with said link turns to second orientation, but said deflector deflection reaches second orientation up to it; When second orientation, said longest dimension is set to closely be entrenched in the shortest size of said slit;
Said link a part of frangible makes that when in use receiving axial load, said link lost efficacy and the chucking power between said distal end flange and the proximal rim is disappeared.
The present invention provides a kind of basically and can axially be connected with the frangible twistlock of two plates of clamping transversely.Link is inserted in the slit of plate and turns round second orientation.Two functions have been realized like this.At first, far-end keeps flange with near-end maintenance flange each plate to be clamped together preventing to separate; Secondly, tight chimeric between the shortest size of bar portion and slit prevents not lining up between each plate.
Because link is frangible, thereby, when receiving Separating force, allow each plate separately when concrete shrinkage.Link is designed to be enough solid transportation and installation to bear plate, but under along with the load type that concrete shrinkage experienced, link is easy to lose efficacy, and the magnitude of this load is less than otherwise destroying concrete load usually.
Link is an element, and does not need sleeve or nut, makes it easily to make.In addition, owing to the quantity reason, simple twistlock process can improve the assembling speed of guide rail.
Though must be so in broad aspect, it is one-body molded that link itself extremely is fit to, injection molding member for example, thus allow cheaply and easily to make.
Each flange surface can be smooth to each face of bar portion.Yet, this means link must with point-device tolerance make with guarantee link can be when the second orientation gripping panel.Therefore, preferably, at least one flange in said each flange is provided with the parts that when it turns to second orientation, produce axial chucking power.These parts mean that in use, the manufacturing tolerances of link and slit is not so crucial, in link, can produce enough chucking powers, and link still can easily manually forward second orientation to.
Preferably, said parts adopt the proximal end face of distal end flange to have the form of camming surface, and when first orientation was rotated, said camming surface provided guiding face, thereby allows between said each flange, plate to be produced axial chucking power at said link.Selectively or extraly, said parts can be the grooves that is positioned on the distal face of said proximal rim, and it has realized identical functions.
But said deflector for example can be the insertion part of being processed less than the flexible material of the remaining part of link by elasticity.Yet preferably, in second orientation, they just lock said link to prevent to leave the rotation of second orientation but said deflector is constructed such that.Through preventing the reverse rotation of link, but deflector can prevent link from the appropriate location accidental removal.
A kind of mode that realizes above-mentioned configuration is; Spring section is a pair of diametrically opposite elastic protrusion part; The main body of each elastic protrusion part and said bar portion separates; Each elastic protrusion part is configured to along with said link rotates and by the main body deflection of said slit towards said bar portion to second orientation, and along with said link is got back to the reference azimuth fast near second orientation, the shortest size of said thus protuberance and said slit cooperate the reverse rotation that prevents said link.In a single day this link can easily be turned round second orientation, but is in second orientation, link prevents reverse rotation with regard to being locked.Protuberance can be integrally formed with the remaining part of link, perhaps can be by processing such as second kind of materials such as metals.
Said engagement head can be the handle that grasps, or with the head of hole, slit or the special shape (for example, Hexagon) that cooperate such as instruments such as screw-driver, sleeve pipe or spanners.Preferably, said handle has flat configuration, because the vision indication of the rotational orientation of link is provided like this.Preferably, the near-end of said handle does not have straight edge, if because have straight edge, will exist so along a plurality of straight edge of track alignment, thereby produce weak spot in the concrete around potentially.Handle can be provided with one or more through holes, thereby allows concrete to pour into handle.
It is frangible that one of bar portion and flange or the two can be designed to.Yet, at present preferably, said far-end keep flange to have precedence over said bar portion or said proximal rim frangible.Distal end flange has little shoulder naturally, and preferably, and on the outermost end plane of the longest dimension of bar portion, the cross section of these shoulders is designed such that the shoulder of proximal rim has precedence over any other and destroys mechanism shear takes place.

Embodiment
Link is injection molding, can be processed by various materials, comprises metal, composite material and polymer.Preferably, link is processed by polymeric material cheaply, so that produce and reduce cost per unit.If desired, injection molding member can utilize the structural elements such as plate such as metal or other materials to strengthen in inside or reinforcing.As known in the art is that in process of injection molding, this structural element can moulding in link.
Link is made up of four parts, that is, begin from near-end, and handle 1, proximal rim 2, bar portion 3 and distal end flange 4 will describe below in more detail.
Handle 1 has the planar structure, and it has the web 5 of the vertical enhancing of proximal rim of extending to 2.The near-end of handle 1 has curved configuration, to reduce the potential line of weakness in the concrete around.Handle 1 can also be provided with the through hole (not shown), to embed in the concrete.Handle 1 enough ambassadors its can the person of being used hand easily hold, therefore, it has length and the width of about 2～3cm.
The narrow dimension of the maximum transverse size X (see figure 7) in the cross section of bar portion 3 and the long slit S that embeds link is corresponding.The length of bar portion is generally 1～3cm by the thickness decision of two plates that will be held.Bar portion has a pair of elastic protrusion part 6 that is connected and separates with main body 7 elasticity of bar portion.As depicted in figs. 1 and 2, these protuberances 6 almost extend along the whole axial length of bar portion, and still the axial end portion at them is freely, thereby allow deflection.Bar portion 3 has a pair of smooth end face 8.Protuberance 6 has the corresponding end-faces 9 with each end face 8 coplane of main body 7.Each end face 8 carries out the transition to crooked shoulder 10.
Distal end flange 4 has taper 11 at its far-end, thereby helps to be inserted in the slit.The proximal end face of distal end flange is smooth substantially, but is provided with a pair of diametrically opposite camming surface 12, below with illustration.
Below will be concrete with reference to figure 7A～7G, the use of link is described.
Plate length along the guide rail that aligns is inserted a plurality of links.The guide rail of each alignment has a plurality of long slit S, and each aligns to long slit.In practice, slit extends along substantially horizontal in use, but link is gone up and can likewise work in any direction.
Under the assistance of the taper on the distal end flange 4 11, link is inserted in the slit of a pair of alignment, passes completely through slit up to distal end flange 4.Then, the work that need do is the 90 ° of rotations of axis around link, connects thereby accomplish.
This 90 ° of rotations have realized multiple function.At first, the camming surface 12 that is positioned on the proximal end face of distal end flange provides guiding face, and when rotating, guiding face is pulled in two plates together, makes distal end flange and proximal rim that two plates are clamped together.
Secondly, along with link rotates (seeing Fig. 7 B) along arrow Y direction, the narrow dimension of slit S causes protuberance 6 towards main body 7 deflections.Along with protuberance 6 to intrinsic deflection, bar portion can rotate in slit.In case through the narrow dimension of slit, each protuberance just freely rebounds under their elasticity in the end of protuberance 6.In this orientation (shown in Fig. 7 G), end face 9 alignment of end face of main body 8 and protuberance 6 and against the wall across narrow dimension of slit, thus gripping panel prevents the opposing vertical motion.On this position, protuberance 6 prevents the reverse rotation of link, and this is that each protuberance can not be returned towards main body 7 deflections of bar portion because when reverse rotation power is applied to link.
Distal end flange 4 has a pair of destruction face Z, and Fig. 1 shows one of them and destroys face Z, and Fig. 4 shows two and destroys face Z.On each position in these positions, the cross section of distal end flange 4 is less than the cross section of bar portion 3.Be applied between proximal rim 2 and the distal end flange 4 at the axial load on the link.Under this load, distal end flange 4 is destroyed face Z place at one or two shear is taken place, and the chucking power disappearance, thereby allows each plate to separate in the axial direction.Usually, each link is designed to have the rupture strength of 10～30KN, but as required, rupture strength also can be higher or lower.
Fig. 8～11 show second example of link.
Second example is identical with first example aspect most of, and identical reference character is used to indicate components identical.There are two main distinctions in second example and first example.At first, the handle 1 of first example is replaced by trepanning.In this case, trepanning is hexagonal so that accommodate the Hexagon instrument, but trepanning also can be and the corresponding any suitable shape of selected instrument.
In addition, secondly, be provided with a pair of diametrically opposite groove 21 (in each figure, only showing one of them groove) on the distal face of proximal rim 2.This plays supplementary function to camming surface 12, thereby, when link turns to locked position, chucking power is provided.In optional structure, groove 21 can be set replace camming surface 12.
