Description

The clamper and the falling-proof safety device that are used for the annex on the falling-proof safety device

Technical field

The present invention relates to annex on the falling-proof safety device of the construction site of feature described in a kind of preorder as claimed in claim 1 is used, the clamper used of warning light particularly, also relate to a kind of falling-proof safety device that is suitable for this clamper.

Background technology

Disclose a kind of falling-proof safety device be used to build the road measures in building site in EP 1 388 612 B1, it is furnished with one and is positioned in two baffle plates between the plumb post, and this baffle plate is formed by a plastic blowing body of usefulness.The tenon of the projection that distributing on the full duration at falling-proof safety device on the grid body of upside at a homogeneous of this baffle plate is to be used for the plant of warning light.Its shortcoming be: because fixed grid body is, can not change the number of the warning light that can plant.In addition, in the scope of construction site, the upside of baffle plate can not be used as smooth handrail, and this is especially for those shortcomings of people Lai Shuoshi that must be hindered through the walking in falling proof device zone.

In DE 20 2,006 005 206 U1, disclose a kind of adapter, be used for warning light is planted on the baffle plate.Adapter is designed to T shape or L shaped, and has a cross member towards the tenon of upper process and a cover tubular to be used for fixing on the baffle plate or on the transverse arm of braking transverse slat.Sleeve forms a tubular body, and it has the depression of a longitudinal side, to be used for sleeve to baffle plate or transverse arm.At this, this sleeve forms the side jaw on both sides, and these two side jaws form one greater than 180 ° angle.Utilize a kind of like this adapter, warning light just can be arranged to by required number on the optional position on the total length of brake baffle.Except required design the resilient side jaw, for sleeve or adapter clip are remained on the baffle plate tightly, can dispose some set bolts, so as to adapter and baffle plate are coupled together.

Except some schemes of addressing previously, also have a series of other form of structure, it can be divided into four groups basically.At first the falling-proof safety device by the blow molding manufactured has the tenon that is shaped regularly thereon.When reversing the alarm signal lamp holder by brute force, the tenon on the baffle plate all can rupture usually, has been used thereby make falling-proof safety device can not be re-used as this device.

With regard to the form of structure of second group, alarm signal lamp holder and baffle plate are riveted, and perhaps use screw fixed on this baffle plate, so they permanently are connected with baffle plate.Have only and just get some fixing holes in the case of necessary.This falling-proof safety device is very restricted in flexibility.

In another group, the alarm signal lamp holder is all on top or the baffle plate of planting from the side or the baffle plate.For this reason, recess, groove or similar depression on falling-proof safety device, have been disposed, to be used to the mechanism of planting.Its shortcoming is: therefore handrail is not concordant.Its consequence is: the handrail position is to have interrupted in the place of being furnished with depression, and forms a weak spot of falling-proof safety device.

Also have a group at last, i.e. the alarm signal lamp holder that can screw in and screw out is as introducing in DE 20 2,006 005 206 U1.

Summary of the invention

Task of the present invention is to provide a kind of clamper, be used for annex, particularly warning light on the falling-proof safety device, this clamper can not cause the structure of falling-proof safety device to die down, be easy to mount and dismount, can not cause the disruption on the handrail, can realize the requirement of cost efficient simultaneously.

Above-mentioned task is to solve in the clamper with feature described in the claim 1.A kind of falling-proof safety device that is suitable for this clamper is the theme of claim 18.

The development that some of notion of the present invention are favourable is the theme of each dependent claims.

The clamper that the present invention proposes is characterised in that: this clamper on the one hand can be by on sleeve to a baffle plate, from rather than permanently link to each other with baffle plate regularly.On the other hand, clamper also has a foot, and this foot is furnished with two side jaws at regular intervals each other, and at this, these two side jaws can pass through at least one set bolt/or through bonding and link with baffle plate.At this, two side jaws should surround an angle that is 180 ° to the maximum at horizon, perhaps statement in another way, and promptly each surface normal of the contact surface that faces with each other of two side jaws must not surpass one 180 ° angle.Contact surface is the plane preferably.Under the situation of the contact surface of bending, surface normal relates to the tangent line or the secant of a part.Even in this case, the angle that is formed by described surface normal is also less than 180 °.That is to say, also can not cause the side of plate washer recessed.Do not having under the situation of set bolt, clamper can only need overcome gravity, promptly need not to overcome possible clamping force, just takes off from transverse arm.The side jaw of the clamper that the present invention proposes abuts on the outside of baffle plate, so the side jaw must not have depression or similar recess.Like this, the handrail of baffle plate can be designed to smooth.Relation according to this, the meaning of " smooth " refers to: handrail (being the upside of baffle plate) extends to the other end from an end of baffle plate and extends on its total length on a height, both do not had the position of projection, does not also have recessed position.Meanwhile, owing to avoided depression or recess, thus avoided the structural weak spot of falling-proof safety device.The number in the hole that set bolt is used is restricted on the little number, preferably is limited to 5 holes.Other hole is possible.If clamper was achieved by bonding with only being connected of baffle plate, just do not needed connecting hole.

A major advantage of the clamper that the present invention proposes is considered to be: its width of measuring transverse to baffle plate preferably is not more than the width of baffle plate.This is not to say, baffle plate must not have depression for clamper.Or rather, in the scope of baffle plate seamed edge on its fixed clamp device, have a process and keep equal widths along total length.Should go up width on seamed edge certainly less than the width of clamper, thereby make clamper on width, be no more than the Breadth Maximum of baffle plate in the bottom.Its advantage is: each baffle plate can be each other closely mutually side by side or also can be stacked on top of each other.Each baffle plate can not be hooked together each other, clamp or swipe in the clamper scope.The bulk density of being furnished with the falling-proof safety device of the clamper that the present invention proposes is very high, but the bulk density with the falling-proof safety device of tape gripper not is the same high at least.Within the scope of the invention, do not get rid of and to use the clamper of width of its width greater than its falling-proof safety device of carrying.

According to a favourable development, two side jaws of clamper have the contact surface that faces with each other, and the residing angle of these contact surfaces is preferably in 130 ° to the 150 ° scopes, particularly between 140 ° and 150 ° in 90 ° to 160 ° scope.At this, above-mentioned contact surface that face with each other, that tilt abuts on the supporting surface of baffle plate, and these supporting surfaces are in and above-mentioned contact surface angle same.Like this, the weight of the warning light after the installation is transferred on the supporting surface of baffle plate planarly, and can realize a kind of contact of gross area basically by configuration certain wedge shape or taper, thus make clamper and baffle plate wedge embedding mutually, and be fixed very safely.This wedge shape is not to finish up with the tip in the top of baffle plate.Or rather, flat relatively configuration is an advantage for the fork-shaped foot of clamper, thereby makes the connecting portion that is used for clamper, and promptly the top of baffle plate is trapezoidal basically on the cross section.Therefore done following setting: even the side jaw of clamper also can be joined to one another through a cross bar, this cross bar keeps certain distance ground, extends with paralleling with a cross tube of baffle plate in installment state.The side jaw that can guarantee clamper by the spacing of this cross bar and this cross tube always abuts on the supporting surface of baffle plate gross area.This cross tube extends between two side jaws, that is to say that the cross tube of baffle plate preferably flatly extends.It is also contemplated that: each cross bar is crooked curved, but still has certain intervals ground to extend.Like this, within the scope of the invention, even on falling-proof safety device, can provide a kind of at the upside handrail of rounding in addition.

Following way can certainly be thought favourable: cross tube flatly extends, because according to this configuration, a set bolt that extends between the side jaw can support on this cross tube from the inside with the linearity contact for fixed dam.Therefore, the hole that is used for fixing bolt can be arranged near the top edge of side jaw very much.This situation just makes might so settle the safety element that is used for fixing set bolt in the side jaw, thereby makes it is set bolt or safety element do not exceed clamper in installment state outline.

Be used for fixing the hole of bolt but also can be furnished with such inwall, this inwall forms a passage in baffle plate.This passage can so be made, and has a bolt to extend in the shaping die cavity exactly when injection molded.Also can dispose two opposed bolts, when opening die cavity, these two bolts can be separated from each other.Owing to be subjected to the restriction of method of manufacturing technology, between the end face of two bolts, or between the end face of a bolt and die cavity, leave slot, this slot is filled by plastics.Plastics overlap joint body must be removed, and the simplest mode is to realize this removing by boring.The inwall of passage can make bolt be supported on the much bigger area.This compressive load per unit area wants much little compared with the sort of bolt that only is supported on the boring area.Therefore, this bolt can not rupture at an easy rate.

When adopting bolt, safety element can be a threaded sections, and this threaded sections directly is formed on the clamper.But also can refer to a nut that is fixed on the clamper.If safety element is a screw element not necessarily.Under the situation that adopts set bolt, safety element also can be a kind of locking member that belongs to the bayonet coupling type, and at this, safety element has at least one stop protrusion, and the stop convex shoulder on this stop protrusion and the set bolt adapts.For example turn round 180 ° by set bolt around its longitudinal axis revolution, the clamper that the present invention proposes just can be fixed on the baffle plate fast and reliably.Set bolt preferably can not be connected with clamper with losing.

In order to prevent the stolen Insurance riders of warning light, can take following measure: set bolt can only be operated with a kind of special tool.

Difference as requested, set bolt can be made of a steel.Certainly, also can adopt plastic components.Say that in principle even under the situation of the falling-proof safety device that adopts the present invention to propose, also do not get rid of following phenomenon, promptly clamper is broken owing to destroy.Always also have following possibility in the case: since the side jaw gross area of clamper abut on the supporting surface, so its foot can be in addition bonding with falling-proof safety device.Like this, falling-proof safety device can overhaul in good time.

According to the present invention, can between side jaw and transverse arm, dispose bonding at the very start.For this reason, contact surface should be enough big.Used bonding adhesive can cause producing a kind of connection that can not unclamp between clamper and transverse arm.This situation just has when normally adopting suitable liquid adhesive.Being used for releasable bonding bonding adhesive may be a kind of material of toughness also, and at this, its surperficial bond properties has been cancelled by the tensile stress on bonding surface owing to being parallel to each other.Bondingly also can be designed to unclamp, for example use a kind of like this bonding adhesive, this adhesive placement is on a kind of carrier thin film.Can refer to a kind of two-sided adhesive tape in the case.

A bonding advantage is: can unload or even replacement bolt connection.Its another advantage is: even without other boring, attached clamper also can be installed on the falling-proof safety device.At this, its starting point is: only arranged a limited number of boring on transverse arm, for example 5 equidistant borings.Other boring also can be set certainly afterwards.The way that substitutes is exactly bonding.

The clamper that the present invention proposes is particularly useful for the baffle plate by the blow molding manufacturing, and at this, this baffle plate is because the former capital of creating conditions is to make with quite soft plastics.Following way can be thought favourable: clamper is made with a kind of like this material, and this material has bigger hardness than the material of baffle plate, thereby has bigger resistivity.This point is not got rid of falling-proof safety device and is had for example lateral stay of harder assembly, and it all is made of steel usually.

The clamper that the present invention proposes also has a kind of fixedly possibility that is used for annex, particularly warning light certainly.At this, preferably refer to a kind of tenon that protrudes upward from foot.This tenon can dispose at least one horizontal boring, so that also warning light can not can be fixed on this tenon with losing, thereby is fixed on clamper or the falling-proof safety device.Tenon certainly must not be wideer than foot, thereby also must not be wideer than baffle plate or falling-proof safety device, and the falling-proof safety device of the clamper of being furnished with the present invention's proposition can be arranged easily and closely each other side by side or one above the other.

Description of drawings

With reference to an embodiment who schematically shows in the accompanying drawings the present invention is elaborated below.Accompanying drawing is represented:

The sectional view that is installed in a clamper on the baffle plate that Fig. 1 the present invention proposes;

The lateral view of the clamper of installing shown in Fig. 2 Fig. 1;

The vertical view of clamper shown in Fig. 3 Fig. 1 and 2;

Another form of implementation of the clamper of Fig. 4 on a baffle plate is by sectional view shown in Figure 1;

The sectional view of another form of implementation of Fig. 5.

The specific embodiment

Fig. 1 represents how a clamper 1 is installed on the falling-proof safety device 2.To falling-proof safety device 2, the baffle plate made from plastics with blow molding method 3 only is shown, this baffle plate is furnished with a Top Crossbeam 4, and clamper 1 is fixed on this transverse arm with its foot 5.Transverse arm 4 has a constant cross section on its overall length, this cross section can be referred to as trapezoidal.Under any circumstance, transverse arm 4 all is diminishing from bottom to top.According to the present invention, transverse arm 4 forms the topmost of baffle plate 3.

Clamper 1 also comprises a tenon 6 to upper process except comprising its foot 5, this tenon is furnished with two cross-drilled holes 7,16 to be used for fixing the not detailed in the drawings warning light that shows.Tenon 6 is that design is cylindraceous.Foot 5 is divided into two

side jaws

8,9, and these two side jaws touch baffle plate 3.For this reason, the relative contact surface 10 that inclines towards each other of

side jaw

8,9 abuts on the supporting surface 11 of transverse arm 4.Surface normal N on the contact surface 10 on plane is in an angle W each other.This angle W is less than 180 °, and all is not more than 180 ° in any zone of contact surface.Even contact surface is crooked, the surface normal that is in the tangent line in knee can not surpass one 180 ° angle.

Opposed supporting surface 11 be in one with contact surface 10 angle same in.Like this,

side jaw

8,9 just reclines gross area.By this embodiment, foot 5 is almost clamped whole transverse arm 4, of course not encases this transverse arm, and is connected with this transverse arm through crossing the set bolt 12 of this transverse arm 4.Here refer to such bolt, its head is to be embedded to fully in the foot 5.By this embodiment, the width B of foot 5 is so selected, and makes that it must not be greater than the width B 1 of transverse arm 4.In a word, the Breadth Maximum of clamper 1 (comprising tenon 6 interior) can equate with the width of transverse arm 4, equates with the width of whole falling-proof safety device or rather.Certainly, within the scope of the present invention, do not get rid of the yet comparable falling-proof safety device broad of clamper.

In the present embodiment, angle W is 145 °, and wherein the upside of transverse arm 4 does not finish up with the tip, but flatly scabble.As can be seen, the contact surface 10 of

side jaw

8,9 neither meet each other with an acute angle degree, but is connected to each other through a crosspiece 13, this crosspiece shown in the installation site on be parallel to baffle plate 3 with a perpendicular separation a top rail 14 extend.Directly extend set bolt 12 below the top rail 14 of baffle plate, this set bolt is supported on the inboard of top rail 14 when stand under load.Like this, the boring on the supporting surface 11 of transverse arm 4 is being subjected to the power that is subjected under the pulling force loading condition less, and this is because set bolt 12 all is supported on the top rail 14 at periphery.Set bolt 12 itself is to be embedded to a nut 15 in the side jaw 9 and maintained through one.Nut 15 is represented the safety element of any form, and a kind of shape that this safety element can be implemented in set bolt 12 in the

side jaw

8,9 is sealed fixing, thereby is implemented in interior this fixing of outline of foot 5.An enhancing portion 17 is arranged below clamper 1, have a kind of reverse drawing form towards baffle plate 3 inside.

Fig. 2 represents the lateral view of clamper shown in Figure 11.As can be seen: on tenon 6, disposed one second cross-drilled hole 16.Also can obviously find out: clamper 1 is not clamped transverse arm 4 fully, and only is to be in basically in the first half of this transverse arm.The horizontal dotted line of being painted in the inferior segment of transverse arm 4 is represented the width position of transverse arm 4.Clamper 1 its foot 5 is not or rather clamped on this wideest position, is an angle of 180 ° to the maximum so

side jaw

8,9 forms at horizon.Below clamper 1, an enhancing portion 17 is arranged, it has the shape that a kind of circle is pressed into, in case since because of the additional load of warning light so strengthen that position of baffle plate 3.

Fig. 3 represents the vertical view of clamper 1.From the figure as can be seen: tenon 6 has a kind of geometrical configuration of circle, and the foot 5 of clamper 1 then is rectangular configuration basically.In the present embodiment, its vertical length of measuring along transverse arm 4 is slightly larger than the width of transversely measuring in the direction of transverse arm 4.

Fig. 4 represents the view identical with Fig. 1 of same clamper, and it has been installed on the falling-proof safety device 2.The difference of this form of implementation of this falling-proof safety device and falling-proof safety device shown in Figure 1 is in the design of the bonding pad between foot 5a and the transverse arm 4a.Difference is the interior another kind of structure of scope of set bolt 12a.Set bolt 12a passes a passage 18, the set bolt 12a shown in the inwall 19 of this passage surrounds.Therefore, set bolt 12a is different from form of implementation shown in Figure 1, is not to be supported on the side of existing boring of baffle plate 3, but is supported on the inwall 19 of passage 18.

The passage 18 that connects or not originally, promptly sealed originally.Owing to be subjected to the restriction of fabrication process condition, in the center crosspiece that dots 20 is arranged, this crosspiece is that boring is come out or punching press is come out, so set bolt 12a can be conducted through this passage 18.According to this form of implementation, only need a unique boring of arranging placed in the middle.The effect of passage 18 is the subsidiary baffle plate 3a that strengthens, and provides higher stability for baffle plate.Crosspiece passage 18 and that herein arrange between two parties 20 adjacent positions are designed slightly taperedly.This point is because of due to the model gradient of the shaping bolt that is used to make.Except the tapering of the boring 21 that is used for fixing bolt 12a and safety element 15a, clamper 1 is not different from clamper shown in Figure 1.This clamper is not to adapt to passage 18 with particular form, perhaps not be to adapt to aperture/depression among the baffle plate 3a with particular form, but on such meaning, promptly this clamper 1 is to embed among the baffle plate 3a.

Similar to Fig. 1, baffle plate 3a has a 17a of enhancing portion, and what this enhancing portion was different with form of implementation shown in Figure 1 is to have a less diameter, and directly be arranged in the below of transverse arm 4a.

Fig. 5 is illustrated in a kind of different form of implementation of foot 5b in the zone that is connected with transverse arm 4b.At this, passage 18a designs slightly taperedly.

Boring 21 on the foot 5b is not to design taperedly as shown in Fig. 1 and 4, but designs to such an extent that have a tubular at the edge of chamfered edge.With shown in Figure 4 different, that this point can realize is standardized, the use of the set bolt 12b of cylindrical.
