Description

Cell structure

Technical field

The present invention relates to the cell structure of a kind of particularly reinforcing bar grid or floor stationary grizzly, comprise a large amount of steel wire steel wire bar that constitute, that be arranged side by side and a large amount of bars that extend parallel to each other especially by the indentation bending, wherein the steel wire of each steel wire bar twines each bar with the ring form of sealing basically.

Background technology

Are known a kind of this type of cell structures for example by GB 191501422.In this structure, each bar of the ring guiding by each steel wire bar is substantially perpendicular to each plane that is made of each zigzag steel wire bar.Though this structure itself is described, that is before the filler of packing into, self-sustaining is constant in the document.But practice shows, though certain initial stability is guaranteed in the setting of bar in the ring of sealing basically, but each ring enlarges quickly again by the motion of cell structure, thereby no longer each bar enough is firmly held in the ring of each indentation steel wire bar.

Practice also shows, a kind of additional fixing welding or installation retaining clip etc. for example passed through, mean that during fabrication additional expense means additional cost then on the one hand, and on the other hand by these connection measures that replenishes, heating may weaken the material of bar and steel wire bar during owing to welding.Influence unfriendly by these additional fixation in addition or damage usually at the corrosion-resistant coating that is coated to before the grid manufacturing on steel wire and the bar again.

Summary of the invention

Therefore the objective of the invention is, improve the cell structure of described type, make it not have the cell structure that a kind of self-stabilization is set up in additional connection measure.

This purpose realizes that so promptly in order to be fixed on each steel wire bar, each bar is clamped in the ring of each steel wire bar, and in the ring that is clamped in each steel wire bar, each bar reverses or is provided with obliquely towards a direction at least with respect to each ring.

By constituting the ring of sealing basically, might be only by clamping being connected between formation steel wire bar and the bar.Because like this force closure that realizes connects being connected that the welding that can abandon bar and steel wire bar or other add.By bar reversing or tilt to realize the clamping of bar in the ring of steel wire bar with respect to the plane, hole of ring.Stop effect known in the prior art whereby, promptly clamp connection because the expansion of the hole width of ring may be loosened again.The cell structure of Shi Xianing is only owing to the clamping action of each steel wire bar and each bar remains unchanged thus.

Can realize the formation of the ring that seals basically by different measures.Can for example set like this, per two legs of each steel wire intersect in an intersection region, so as to constitute one of them, preferred whole ring, wherein, each leg of steel wire each other the minimum spacing in the intersection region less than three times of the steel wire rugosity, particularly less than the steel wire rugosity.But additional or replacements is also possible, and the steel wire by each steel wire bar is made a ring that seals basically repeatedly around the ring center spirality rotation of an imagination.This will realize like this that promptly in order to constitute the ring of sealing basically, the steel wire of steel wire bar is reeled more than 360 ° around this center.In this variation scheme, each spiral coil that constitutes by steel wire also advantageously closely reclines each other.

Preferably set each bar fixing in the ring of each steel wire bar based on additional each other the reclining of two adjacent rings.At this whether owing to other reason is installed additional jockey etc. with inessential, even as long as structure also still keeps self-stabilization by clamping action after removing these additional Connection Elements on each tie point between steel wire and the bar.Except that pinch effect, also can further improve stability of structure in case of necessity by the supporting each other that reclines mutually then of two adjacent rings.

Though the clamping of each bar in the ring of each steel wire bar is by reversing or tilt to become possible towards a direction, but preferred form of implementation is set, each bar reverses or is provided with obliquely towards both direction at least with respect to ring, so that be clamped in the ring of each steel wire bar.By inclined twice or reverse and cause a kind of strong especially clamping action.If the area of an endoporus of a ring is so big, so that the bar plane, hole that is substantially perpendicular to ring when it is provided with can move freely basically along the vertical direction of stretching of described bar, then can make such cell structure especially simply.

Cell structure not only can be used for concrete reinforcement but also be used as the floor stationary grizzly.

The specific embodiment

In pressing the cell structure of Fig. 1 to 10, steel wire bar 1,1 ' by each ring 3 around

bar

2,2 '.One on each bar 2 ' be arranged on go up plane 4 ' in.Each lower beam 2 is arranged in the lower plane 4.By the

plane

4 and 4 of bar 2 and 2 ' constitute ' between spacing 7 for bar 2,2 ' many times of maximum gauge, preferably at least ten times.Therefore realize a kind of structure of three-dimensional, this structure not only guarantees good stability or stabilisation as concrete reinforcement but also as stationary grizzly.Two adjacent legs 6 of steel wire bar 1 and 6 ' intersect, so as intersection region 5 in formation ring 3.Here two legs 6 and 6 ' mutually recline or only separate very little spacing each other.Minimum spacing in intersection region 5 at these three times, preferably less than the steel wire rugosity less than the steel wire rugosity.Primordial originally goes up ring 3 of sealing whereby.Therein by towards the clamping of two different directions, fixing described bar 2,2 ', as following also to describe in detail by Fig. 5 a-7c.

Each steel wire bar 1,1 ' on the meaning on plane basically, constitute, make each steel wire bar perpendicular to its vertical stretch 9 and perpendicular to its height of horizontal wide 10 less than steel wire bar 1,1 ' five times of steel wire rugosity, preferably less than three times.The position on the plane that is made of them is shown in the side view of cell structure by Fig. 2.On the accurate meaning of mathematics, by zero the steel wire rugosity of being similar to of the imagination, the plane that draws each steel wire bar.Can be clear that equally among Fig. 2, two be adjacent to be arranged on each bar 2,2 ' on steel wire bar 1,1 ' the interlocking mutually of each ring.This is favourable on the meaning of the simple manufacturability of cell structure especially.Though adjacent ring is interlocking mutually, only by the clamping of bar 2,2 ' in each ring 3, supports by the mutual supporting of adjacent ring 3 in case of necessity, and the enough intensity of cell structure still is provided.As can finding out on by the vertical view of Fig. 1 especially like that, steel wire bar 1,1 ' only be provided with in the direction, this direction its vertical stretch 9 perpendicular to bar 2,2 ' vertically stretch 11 extensions.Therefore do not need along bar 2,2 ' vertical stretch 11 directions or with its diagonally or along other directions be provided with additional

steel wire bar

1,1 '.Like this for each bar 2,2 ' too.Each bar shown in each embodiment in also only be provided with in parallel with each other.Therefore the

preferred bar

2,2 that does not extend transverse to direction 11 '.Even cell structure shown in steel wire bar 1,1 ' and bar 2,2 ' between orientation in also reached the intensity that needs.But this situation has also been simplified the manufacturability and the stackability of general construction.But the good stackability by the flase floor of the present invention that stacks has mutually not only dwindled stock's volume or transportation volume, but also has improved the stock and the transportation stability of cell structure, and this has not only brought the cost advantage but also has brought the quality advantage.

Bar 2,2 ' in the embodiment shown constitutes straight and has a circular cross section.This preferred settings, owing to do not need especially bar 2,2 ' carry out moulding, this has simplified the manufacturability of grid again.But in other form of implementation also might with bar 2,2 ' by the requirement of general construction constitute crooked or with its cross section constitute be different from circular.As requested and application purpose, can Different Plane 4,4 ' interior employing have the

bar

2,2 of identical moulding and identical tensile strength '.But also might Different Plane 4,4 ' interior employing by different materials and/or have different tensile strength and/or have the

different bar

2,2 of different-diameter '.When on two planes 4 and 4 ' when interior tensile load varied in size, this can be favourable at cell structure during as the application of concrete reinforcement especially.But in order to mate the tensile load of general construction, except that these measures, can also to the

adjacent bar

2 or 2 of respective planes 4,4 ' interior ' spacing mate.For high tensile load, can be for example plane 4,4 ' in be provided with less bar 2 or 2 ' spacing, then stretch 9 and obtain more a plurality of bars thus along vertical.So this obtains a less angle β (see figure 2).For little tensile load, can select corresponding bigger spacing or angle β.

Can also utilize in concrete construction especially in addition can be for the intermediate space 13 that freely uses for this reason, so that the object of for example packing pipeline, vacant duct into or having less density there.Object by less density then can be in the core of general construction saving in weight because do not need concrete here.If pipeline or vacant duct are packed in the free space 13, then this is a kind of simply and cleverly method, so as in concrete bodies water piping, electric wire or other supply line.

In pressing the embodiment shown in Fig. 1 to 10, steel wire bar 1,1 ' or its ring 3 by reversing or inclination and bar 2,2 ' be clamped together towards two different directions.Fig. 5 a-5c be used to illustrate by with respect to each bar 2,2 ' towards a first direction reverse steel wire bar 1,1 ' clamping.By Fig. 6 a-6c illustrate steel wire bar 1,1 ' with respect to each bar 2,2 ' towards a second direction the inclination that adds.Fig. 7 a-7c illustrates final result.

Fig. 5 b illustrates cell structure at first at bar 2 ' can freely be inserted into the basically vertical view of the position in the ring 3.The area of the endoporus of ring 3 is chosen to so big at this, the plane, hole 14 of so that bar 2,2 ' be substantially perpendicular to when it is provided with ring 3 is vertically stretched 11 directions and be can move freely basically in ring 3 along it.In this position, can be with bar 2 ' be inserted in the ring 3.In order to realize clamping, the steel wire bar by leg 6,6 ' expression is then towards rotating in the direction of arrow shown in Fig. 5 b, up to its in the vertical view shown in Fig. 5 c, be substantially perpendicular to bar 2,2 ' vertically stretch 11 settings with reversing.In this position, bar 2 ' by having reversed towards a first direction owing to clamping very firm remaining in the ring 3.In order to realize this point, plane, hole 14 with one be different from 0 ° angle with respect to steel wire bar vertical stretch 9 or with respect to steel wire bar 1,1 ' plane 12 be provided with.Angle between the plane 12 of plane, hole 14 and the steel wire bar spacing of size, steel wire rugosity and the

leg

6,6 of the area of the endoporus by ring 3 ' intersection region 5 in an illustrated embodiment is scheduled to.In order just to realize a kind of enough firm grip in this position, the corner α between 20 ° to 30 ° is favourable.In an illustrated embodiment, α is about 25 °.Advantageously, the angle between two

planes

12 and 14 equals desired corner α.Fig. 5 a be illustrated in by the bar 2 before beginning to reverse in the side view of Fig. 3 ' and steel wire bar 1 between the position, that is in the position shown in the vertical view of Fig. 5 b.

Except by the reversing of Fig. 5 a to 5c, steel wire bar 1,1 ' in an illustrated embodiment also in the side view of cell structure with respect to steel wire bar 1,1 ' vertically stretch 11 and be provided with obliquely with an angle β who departs from vertical line 8.Fig. 6 b be illustrated in paint in this figure into the side view of the state of the direction of arrow before tilting.Fig. 6 c shows and finishes later state.Angle of inclination beta advantageously is between 20 ° and 40 °, about in an illustrated embodiment 30 °.By the side view of Fig. 6 c is detail drawing from Fig. 2, wherein paints equally into angle of inclination beta.When making cell structure, at first in the position shown in Fig. 5 b with bar 2,2 ' be inserted in each ring 3.And then be torqued into position, that is reverse towards a first direction by Fig. 5 c.Then in another job step towards a second direction described angle β that tilts, this is created in the position shown in Fig. 6 c.Fig. 7 a, 7b and 7c show and are used to illustrate that this reverses and the detail drawing of the final result that tilts.Though advantageously by rotate or tilting procedure both cause bar 2,2 ' be clamped in steel wire bar 1,1 ' ring 3 in, then still possible, only by reversing or only fixing by tilting to produce.Be clear that in addition, when reversing and/or tilt, only depend on steel wire bar 1,1 ' and bar 2,2 ' between relative motion.Otherwise the therefore whether

steel wire bar

1,1 of bar 2,2 ' relatively ' reverse and/or tilt or be inessential.

The steel wire rugosity be generally less than bar 2,2 ' minimum diameter.On a kind of meaning of firm grip as far as possible advantageously, the steel wire rugosity be at most bar 2,2 ' half of minimum diameter.

Advantageously, steel wire bar 1,1 ' steel wire have the steel of steel wire rugosity between 1.6mm and 2.8mm, or constitute by a kind of such steel.According to the purpose requirement, be typically chosen in 400 and 600N/mm in the tensile strength of the material of this employing ²Between.Bar 2,2 ' generally has the tensile strength higher than steel wire, mostly 400 and 2500N/mm ²Between scope in.But bar 2,2 ' not only can be made of corresponding steel, and for example also can be made of plastics preferred high tensile and/or fibre-reinforced, or has this plastics.Also to consider corresponding tensile strength values here.

If select steel as be used for bar 2,2 ' or steel wire bar 1,1 ' the material of steel wire, then for anticorrosion, a coating that preferably is made of one or more zinc or zinc alloy layer can be set.This in a kind of cell structure of the present invention advantageously, at first be coated to bar 2,2 ' and steel wire bar 1,1 ' steel wire on coating can not be damaged owing to the manufacturing of structure or influence.Replace coating, also can select a kind of stainless steel of corresponding formation for anticorrosion naturally.When selecting material and coating, the technical staff can employ existing standard.These standards that are used for concrete arrangement of reinforcement are EN 10080.Also can select some materials else, they are known according to the EN 10223 that is used to make fence.In the EN 10264 of the manufacturing that relates generally to steel wire rope, the technical staff also can obtain corresponding material report.Also can use the EN10337 that is used for compressor wire and be used for concrete arrangement of reinforcement and prestressed EN 15630-1.Use EN 10244 when needing about being used for etch-proof coating.In EN 10088, obtain corresponding stainless steel.The selection of material also will consider, upper boom 2 ' with lower beam 2 whether by same material manufacturing with identical tensile strength, should accord with corresponding requirement all the time, so that guarantee to using the best coupling of purpose.

Fig. 8 a to 8d show

bent steel strand

2,2 how ' the different possibilities of end.But the bending of end is not necessarily essential.For this reason can by Fig. 8 a and 8b be provided with bar 2,2 ' the hook design of end, to hook such hook in adjacent plate of described structure etc.If save the overlap joint of intending abandoning two adjacent cell structures for material, the terminal of ring-type then can be set by Fig. 8 c and 8d.Might utilize an inserted link that is inserted in the ring to connect two plates or cell structure by this ring.If saving, material not necessarily is in critical role, then also can be simply by two plates of staggered realization of two adjacent plates or the connection between the cell structure.Particularly advantageously for this reason be, as shown in Fig. 1,3 and 4, cell structure is stretched a side of 9 steel wire bar 1 vertical and is ended up with a lower beam 2a, and at opposite side with a upper boom 2b ' ending.In this structure, in order to connect each plate, it is just enough that they are crisscross arranged simply.Fig. 9 a to 9c illustrate can how to constitute steel wire bar 1,1 ' the different variation scheme of steel cord end.

For the structure height of cell structure, that is plane 4 and 4 ' or bar 2,2 ' the center between spacing be 45mm, 75mm or 100mm, advantageously selecting diameter is the steel pull bar of 3.0mm.When structure height was 125mm, advantageously, shank diameter was 4.0mm mostly, and when structure height was 150mm, shank diameter was 5.0mm.The length of cell structure or plate, that is its extension along direction 11 is matched with needs and transportation possibility basically.Cell structure is being used as in the civil engineering of floor stationary grizzly, the plate length of about 3m usually is preferred.When using as concrete reinforcement, grid length can be according to the present-day standard structure length.For example be 3,4,5,6,8 and 12.50m.But can be with length and size manufacturing arbitrarily however, according to structure of the present invention.In the construction site also is possible by the length and the width blanking that are fit on the spot at any time.

Figure 10 shows a side view that is similar to Fig. 2, each ring 3 needn't direct neighbor or be arranged on against each other bar 2,2 ' on.By Figure 10 also can select per two adjacent steel wire bars 1,1 ' along bar 2,2 ' vertical 11 the bigger spacing of stretching, this causes material and weight to be saved.

But by the advantage that first embodiment of Fig. 1 to 4 has be, adjacent steel wire bar 1 and 1 ' ring 3 when high load capacity except that clamping can also the supporting mutually.

In pressing the embodiment of Fig. 1 to 10, in order to constitute one of them ring, per two

legs

6,6 of steel wire ' in an intersection region 5, intersect, each ring 3 constitutes sealing basically, wherein, the minimum spacing of leg 6,6 ' each other in intersection region 5 of steel wire is less than three times of the steel wire rugosity, particularly less than the steel wire rugosity.But this is not to produce unique possibility of closed ring basically.

Figure 11 a and 11b show a kind of variation scheme with the detail drawing that is similar to Fig. 7 b and 7c, and wherein, in order to constitute ring 3, steel wire is reeled more than 360 ° around the center of the imagination of ring 3.A kind of spiral setting that in the zone of ring 3, produces steel wire thus.This is external by also will additionally satisfying standard among the embodiment shown in Figure 11 a and the 11b, i.e. three times steel wire rugosity of leg 6 and 6 ' be not distal to away from each other in intersection region 5.But needn't necessarily set like this, because ring 3 seals basically by the spirality setting of steel wire.Each steel wire in the zone of ring 3 advantageously once more against each other.In this embodiment also can be with bar 2 or 2 ' reverse and tilt so that be clamped in the ring towards both direction.Similar as among Fig. 5 a to 6c for shown in first embodiment like that.But particularly in the spiral design of ring, in each ring 3 only tilt or only torque rod 2,2 ' usually be enough.

Difference at the 4th embodiment shown in Figure 12 a and the 12b is, leg 6 and 6 ' do not intersect.They reel more than 360 ° along direction of rotation.But improve stackability whereby.

Except that described difference in the formation of the ring that seals basically, can be similar to two embodiment shown in previous and implement third and fourth embodiment, thus can cancel to the diagram of whole cell structure and to other details explanation and consult explanation to other embodiment.

In a word, provide a kind of treat simple make but on its structure very stable cell structure.The

steel wire bar

1,1 that extends transverse to the supporting direction ' with bar 2,2 ' be pressed into or other additional being connected all is unnecessary because be exactly sufficiently stable originally based on the connection of clamping.Therefore also obviously reduced the manufacturing cost of cell structure.Also realize a kind of good especially clamping of filler during as the application of floor stationary grizzly at cell structure because upper boom and lower beam 2,2 ' between produced a kind of bar of steel wire closely diagonal angle and clamped.
