Description

Upright fence post

Technical field

The present invention relates to the fence formed by the backplate that fixes on the ground by column.Especially but be not uniquely, the present invention relates to the fence of forming by the wire lath backplate that is supported by metal upright post.

Background technology

By the known a kind of metal upright post of FR2676488, two flanks are arranged, the montant that each flank can fixing metal net one end.In order to pass the wire lath cross bar that intersects with montant, each flank comprises some cross bar receiving channels, along the height distribution of column.

A problem of this mode is, can take off wire lath from column, for example by reducing the pulling force of wire lath, takes off montant from winglet.Like this, one has the people of bad attempt just can open fence.

Summary of the invention

Main purpose of the present invention promptly solves such problem.

For this reason, an object of the present invention is the column of a fence, its effect is to support backplate a position that is called the final position, and described backplate comprises a montant at the one end, is called sideline and some cross bars, and described column comprises:

-one fixed groove that is used for fixing described sideline,

-some grooves are called major trough, and its shape makes that in the time of in the sideline is fixed on described groove, the above cross bar can pass described major trough in the final position of described backplate,

-one barrier, its position and major trough equal height, and the cross bar that is in the final position constituted stop that come out from major trough to stop described cross bar, this barrier is called anti-infringement wall again.

Like this, by on column, increasing an anti-infringement wall,, also can stop and take out the sideline of inserting fixed groove even when the backplate of fence is not tight between two columns.In fact, described anti-infringement wall can form a block, resists the power of backplate being taken out from column in attempt.Be appreciated that described anti-infringement wall preferably forms a block that only withstands on the cross bar, be spot distribution along the height of column, and and the nonessential sideline that heads on, therefore, this anti-infringement wall just can not increase greatly wire lath is installed to complexity on the column.

Here point out that this anti-infringement wall is fixed on the column in permanent inactive mode.Therefore it is different from one wire lath is installed to the parts that add again after the final position on the column, and the shortcoming of such parts is that it is easy to be had the people of bad attempt to disassemble.Preferably, the remainder of described anti-infringement wall and column is one-body molded, or strikes up partnership by welding.

In addition, described anti-infringement wall applies a block to cross bar, stops the sideline to be left from fixed groove by blocking cross bar.Normally, described groove has a bottom surface, and described barrier is in the face of this bottom surface, and extends along the direction that is basically parallel to this bottom surface, purpose be with cross bar with eminence basically sideline " sealing " in described groove.

In general, described column is a metal.

Described column can comprise following one or more technical characterictic in addition:

-described column comprises other grooves, is called mounting groove, and is staggered with described major trough in the vertical direction, and defined a centre position for described cross bar, breaks away from anti-infringement wall at this position cross bar.Like this, in the time of in cross bar is received within mounting groove, they break away from described anti-infringement wall, that is to say, described anti-infringement wall does not form the block that heads on them.In other words, in the time of in cross bar is received within mounting groove, one of cross bar moves is possible, and particularly permission is inserted fixed groove or moving of therefrom taking out to the sideline, thereby has allowed its installation and removal.

-described mounting groove is the extension of described major trough.In other words, mounting groove can and be put (juxtapos é es) with major trough, be close to the major trough position thereon or its down, a part of girth of Ding Yi opening is stepped thus.

-described column is formed by a shell, is a hollow body basically, and described anti-infringement wall is formed by the part of this shell.

-described column is the I type haply, and described anti-infringement wall comprises some thin slices, perpendicular to the center framework of column extend to a sidewall of described fixed groove.The benefit that column is the I type is to be fixed on it on the ground by precast concrete plank.

Another object of the present invention is a method on the upright fence post that backplate is installed in above-mentioned definition, comprises following sequential steps:

-described fixed groove is inserted in the sideline,

-translation backplate vertically, make cross bar be positioned at and major trough with high,

-rotate backplate to the final position along the sideline.

Preferably, the step of inserting the sideline is finished by the combination of a translation and a rotation.

The specific embodiment

Fig. 1 has shown a part of fence.Described fence is by being used for safeguarding that the column 10 of fence protected apron and wire lath backplate 12 form.In the present embodiment, column 10 is a shape, at 16 places, upper end of described column protective cover (capot) has been installed.In addition, backplate 12 also is made of metal in the present embodiment.

Column 10 can make backplate 12 fix on the ground in a different manner, for example by imbedding the pin 14 of column underground, by at the inside of column 10 concrete perfusion and use fixed head, the pin 14 of column is linked to each other with parapet, or from the side column 10 is clamped by precast concrete plank, concrete slab 16 is as shown in Figure 1.

Show that as Fig. 1 and other accompanying drawing wire lath backplate 12 is equipped with montant 18 or perpendicular wire, they prolong the Z axle and extend perpendicular to the ground direction, and cross bar 20 or horizontal wire, and they prolong the direction that is parallel to ground and extend.For example, (X Z) extends two backplates, the 12 Yangjing faces among Fig. 1.In montant 18, be positioned at backplate 12 ends and be used for the montant that backplate and column 10 collude together is called sideline 22.In addition, in cross bar 20, some bars 24 can lateral alternate, forms on the plane of backplate 12 definition and protrudes, and makes backplate firmer.

Fig. 2 a and 2b have shown a kind of embodiment of column 10.In this example, column is formed by hollow body shell 30.Here, wire lath 12 comprises the cross bar 20 of crossing sideline 22.

Column 10 comprises the fixed groove 32 in a sideline 22, and its shape makes and sideline 22 can be fixed in the column 10 when the final position.In this example, groove 32 has a U type profile and comprises three plates that prolong vertical direction Z extension, is respectively two sidewall 32a and 32b and a diapire 32c.Wall 32c is solid, and that is to say does not have hollow out, and wall 32a and 32b are hollow outs, comprise the many places groove, and is as mentioned below.

Wall 32a comprises some grooves, is called major trough 34, and its shape makes that when backplate 12 was on the final position, cross bar 20 can pass, shown in the right half part of Fig. 2 a and 2b in described major trough.That is to say that when sideline 22 was fixed in the groove 32, cross bar 20 can pass from described major trough 34.Sidewall 32b comprises major trough 35 equally, and its shape makes, when backplate 12 during in the final position, cross bar 20 can pass at described major trough.

In addition, the side plate 32b of groove 32 also comprises some grooves 36, is known as mounting groove 36, is in staggered distribution with respect to major trough 34.Mounting groove 36 is extensions of major trough 34, and they are placed in the top and the adjacent groove 34 of groove 34 side by side.

Shell 30 also comprises a barrier 37, and (X Z) goes up extension, near plate 32b and vertical with it on the plane in the present embodiment.Described plate 37 is called anti-infringement wall.Should mainly distribute and major trough 34 same eminences by anti-infringement wall 37, be used on the final position, forming the block of cross bar 20, stop it from major trough 34, to break away from.That is to say that anti-infringement wall is a block that is used for stoping sideline 22 disengaging from admit groove 32.Described anti-infringement wall 37 forms in the plane parallel with slot opening, that is to say basic parallel with the diapire 32c of groove 32.Like this, shown in the right part of Fig. 2 a, described anti-infringement wall 37 has constituted the block of bar 20 ends on the Y direction, stops sideline 22 to be moved on opposite direction-Y.

Anti-infringement wall 37 prolongs by the limit (retour) 38 of returning on the shell, and (Y Z) goes up extension on the plane.

Describe now backplate 12 is installed in the process on the column 10 shown in Fig. 2 a.At first sideline 22 is inserted in the groove 32, will be about 90 ° in the present embodiment with backplate 12 with respect to α angle of X-axis inclination for this reason.Be not subjected to the obstruction of cross bar 20 in order to make sideline 22 can insert groove 32, need cross bar 20 is placed the height of mounting groove 36, make the end of cross bar 20 be placed in these mounting grooves 36.

In case sideline 22 is inserted in the groove 32, bar 20 also has been included in the groove 36, and carry out a small rotation this moment, and this rotation makes the wire lath 12 subsequently can translation on vertical direction Z.By reducing backplate 12 a little, make cross bar 20 be placed on the height of major trough 34,35.At last, backplate 12 22 is rotated along the sideline, makes it arrive final position with respect to column.In this position, the end of cross bar 20 is stopped by anti-infringement wall 37, perhaps can be stopped by it.

Can observe, can not from column, be extracted in case be positioned on the final position (as Fig. 2 a, shown in the right part of 2b) backplate 12, unless rotate to an angle with respect to column again and translation vertically it, make cross bar 20 pass mounting groove 36.

Can also observe in addition, backplate 12 in column 10 installation and bayonet lock (

) installation similar, all comprised the peaceful in-migration of rotation and guaranteed that it fixes.

Fig. 3 a, 3b have shown second kind of embodiment of column 10.Represent with same part number with similar parts in the prior figures.

In this embodiment, admit groove 32 ' to comprise wall 32 ' a, 32 ' b and 32 ' c, described groove 32 ' towards different with column 10 shown in Fig. 2 a.In fact, the diapire 32 ' c of described groove is substantially in that (Y Z) extends on the plane, perpendicular to the directions X of final position upper guard board 12.In the present embodiment, form in the cavity that groove 32 ' forms in shell 30.The cross section of described cavity 40 is mushroom-shaped substantially.The sidewall 32b ' of groove 32 ' is being supported at the end 42 of cavity.Mushroom part 40 is supporting barrier 37 ' in the part on groove 32 ' opposite, and described part is prolonged substantially in the plane that is parallel to diapire 32 ' c and to be extended, that is to say basically on the plane (Y, Z) in.

In addition, anti-infringement wall 37 ' comprises the staggered mounting groove 36 ' of some in the vertical directions and described major trough 34 '.In this example, these mounting grooves 36 ' are not the extensions of major trough 35, and 10 on column comprises a kind of major trough 34 '.

The mounting means of backplate 12 shown in Fig. 3 a, the 3b is described below.

With Fig. 2 a, the mounting means of 2b central post is similar, at first fixed groove 32 ' is inserted in sideline 22, simultaneously cross bar 20 is passed mounting groove 36 ' and angle [alpha] of backplate 12 inclinations, is about 90 ° in this embodiment.After placing sideline 22 within the groove 32 ', angle [alpha] of backplate 12 additional rotation greater than α ', make an end of cross bar 20 insert cavity 40 the insides, and it is broken away from mounting groove 36 '.In this position, mounting groove 36 ' is no longer from vertical direction constraint cross bar 20, therefore can in the vertical direction translation backplate 12, it is descended a little, so as cross bar 20 to be placed and major trough 34 ' with height.The 22 rotation backplates 12 along the sideline make backplate 12 reach the final position, shown in the right half part of Fig. 3 a, 3b then.

In this final position, can find that anti-infringement wall 37 ' constitutes the cross bar 20 that is in the final position and stop that the bottom surface 32 ' c that is in reverse to groove 32 ' is to its support force that applies on the directions Xs; Thereby, when be subjected to an intention sideline 22 from fixed groove 32 ', take out mobile the time, this stops and can stop cross bar 20 to leave from major trough 34 '.

Fig. 4 a has shown a column 10 by another kind of embodiment to 4f.This column is the I type haply, and a center framework 50 is arranged, and is connecting the shape (formes profil é es) 52,54 of two moulding.Described skeleton 50 and described section bar 52,54 delimited the boundary in a space 56 together, and described space 56 is used for holding concrete slab, with vertical columns 10.Described column 10 is axisymmetric about skeleton 50 haply.

The shape 52 of described moulding is the protuberance of a protrusion.

The shape that is used for fixing (forme de fixation) 54 comprises two identical parts 57, and each is used to admit a backplate 12.Each part 57 delimited the boundary that has the space 58,60 of hole on two profiles.The boundary in described space 58 extends (X by one, Z) bottom surface on the plane 62, extend (Y, Z) the described skeleton on the plane 50, one are parallel to the transverse wall 64 of skeleton 50 and one and extend that (X, the wall 66 of be parallel to described bottom surface 62 Z) on the plane, haply, being made up of thin slice 68 delimited.

Described space 60 is fixed grooves 60 that are used for fixing described sideline, the groove 32 among its effect and the preceding figure, and 32 ' is similar.This groove 60 has a discontinuous surface.Its boundary delimited jointly by following part: extend (X, Z) prolongation 70 of the thin slice on the plane 68 equally; A bottom surface 72 that is parallel to described sidewall 64 haply; And a sidewall 74 that is parallel to described prolongation 70 haply, form an interlayer (doublure) that constitutes by the flakelet 76 that extends out from sidewall 64 in this example.In this example, described surperficial 64,76,74,72,70 and 68 come from same integral body, as shown in the figure, and the upper right corner part of Fig. 4 c particularly.By wall 70,72,74 sections of having delimited the groove 60 of boundary are the U type haply, so that fix described sideline 22 on the directions X perpendicular to bottom surface 72, shown in Fig. 4 c.Here point out that in this example, thin slice 68 extends to a sidewall 70 of described fixed groove 60 perpendicular to described center framework 50 ground.

Described part 57 also comprises major trough 34 ", it is arranged so that when described backplate is on the final position and can be passed by cross bar 20, and is as shown in Figs. 4a and 4b.It comprises mounting groove 36 in addition ", with described major trough 34 " in the vertical direction staggered and, in this example, as the extension of described major trough, be close to the major trough position thereon or its down.In other words, as shown in the figure, mounting groove can and be put with major trough, and is stepped to form one.

Here point out that described flakelet 76 forms unhook place (d é crochement) 78 with described wall 64, to guarantee mounting groove 36 " passage unimpeded.

Each thin slice 68 comprises a upper end 69, constitutes an anti-infringement wall, its position and major trough 34 " with high, the cross bar formation that is in the final position is stopped.Particularly, the bottom of cross bar 20 rests on described surperficial 69, and when moving them in order to take out cross bar from described groove 60, this surface forms a prevention cross bar 20 from major trough 34 " the block that leaves.In addition, the upper end of described thin slice 69 does not arrive mounting groove 36 " height, that is to say when cross bar 20 to place groove 36 " time, they can prolong directions X and move, and can not be subjected to the constraint of the upper end of thin slice 68.

Fig. 4 a is described below to the process that shown in the 4f backplate 12 is installed on the column 10.

First step of this process is that described sideline 22 is inserted in the described fixed groove 60, by backplate 12 is tilted to directions X at an angle alpha ', configuration as shown in Fig. 4 e.In this example, described angle [alpha] ' be about 30 °.By cross bar 20 is placed groove 36 " height, described sideline 22 can be inserted in the described fixed groove 60, because at this height, cross bar 20 passes above the upper end 69 of thin slice 68, thereby can not be subjected to the constraint of the upper end of thin slice 68 just.

In case described sideline 22 is inserted into 60 li of grooves, just can be, makes backplate descend a bit, and make cross bar 20 be in groove 34 backplate 12 downward translations " height; After this step, shown in Fig. 4 f, 22 rotation backplates 12 make cross bar 20 insert major trough 34 to the final position along the sideline " lining.Shown in Fig. 4 a, 4b or 4f, on this backplate 12 final position with respect to column 10, cross bar 20 is positioned at the position in the face of the top 69 of thin slice 68, thereby make cross bar 20 backplates 12 not move along directions X, like this, even backplate 12 may cause a gap can taking out it in the column because certain profile (galbe) is arranged, can guarantee that also fence can not be opened.The upper end 69 that is appreciated that thin slice 68 constitutes a barrier that is parallel to groove 60 bottom surfaces 72.

Here point out mounting groove 36,36 ', 36 " defined a centre position for cross bar 20, hereinto between the position, cross bar 20 breaks away from anti-infringement wall 37,37 ', 69.

Fig. 5 has shown the variant of Fig. 4 a to the 4f central post.This column 10 has a similar structure, but materials still less.Particularly, bottom shape 54 ' only forms with parts, rather than is separated into two parts by center framework.

Column 10 can adopt other shape different with foregoing description.

Be appreciated that one of major advantage of the present invention is, the configuration of column 10 makes the installation mechanism of backplate 12 be similar to bayonet lock mechanism, and this anti-invasive to backplate 12 fixedly is effective especially.In fact, in case backplate 12 is fixed on two as between the column of column 10 time, it is not rotated some with respect to column and can not take off it from column.And when fence was in its position, such rotation was impossible.

In addition, in the column of Miao Shuing, the shape of Fig. 4 a and column shown in Figure 5 more helps being fixed on the ground by the concrete slab of clamping it from the side in the above.And, Fig. 4 a to another advantage of column shown in Figure 5 is, it can be used the wire lath backplate 12 that cross bar 20 is no more than the sideline, transportation to backplate 12 is favourable like this, because it can avoid installation personnel folding again this step in end that can flexible cross bar 20 in the transportation.

Above-mentioned various column can have no the support of assurance backplate 12 under various directed situations of difficulty, both can be alinement, two backplates 12 that form 180 ° of angles, also can make them form the angle of a reservation, to form the enclosure wall of arbitrary shape.

Similarly, the profile of above-mentioned column all is realization and firm especially easily, and its manufacturing cost also is very low.

In addition, because described column does not need to be used for fixing the interpolation part of backplate, can avoid especially opening fence by the dismounting fixture.And the installation of described column is easy especially.
