Welded wire mesh

The invention concerns: welded wire mesh to concrete armouring from itself crossing staffs and/or Dr'ähren, with which in the boundary region alternating first sections, in which at least two staffs verlau£ende transverse to the edge are connected by Verbindnngsstäbe, are intended and second sections without Verbindnngsstäbe. Are become known to matte this kind by the German disclosure writing 1609808; at an edge of the well-known mat only distributor staffs are present in the intended coverage, that are connected in pairs by assembly connecting pieces. The assembly connecting pieces are installed on the other side like the carrying staffs onto the distributor staffs. One reaches Hiedurch that when covering two mats the carrying staffs of both mats remain in the same level. The Erf'mdung is the basis the task to create a welded wire mesh with which a cover under Beäbehaltung of the level is possible both the longitudinal bars and the transverse staffs, whereby the ends connecting Stabbzw. Pieces of wire in one of the two levels Längsbzw. Transverse staffs lie. In addition the erf'mdungsgemäße Banstahhnatte is to be simply into a Stützbewehmngsmatte convertible, which lends a shear check at the same time, whereby with the impact of two such mats the guarantee is to be likewise given that Längsund of transverse staffs of the pushed mats lie in each case in the same levels. With a Banstahlmatte of the kind introductory specified the task is solved according to invention thereby that within the intended coverages in each case the second sections without Verbindnngsstäbe around at least double Stabbzw. Wire thickness than first are larger. Opposite the Banstahhnatte in accordance with the German Offenlegungsschrfft 1609808 the welded wire mesh according to invention possesses the advantage that the ends connecting Stabbzw. Pieces of wire in one of the two levels Längsbzw. Transverse staffs lie. Hiedurch is substantially simplified the manufacturing, since for the pieces of staff the same electrodes and supply devices can be used as flir the remaining staffs of the mat. With the Ansführungs£orm after the German O££enlegungssehrfft 1609808 the assembly staff must --3-- compellingly in a third level lie, so that moving of the mats with cover is possible. Furthermore a mat from Swiss Fatentschrift Nr.463754 is bekauntgeworden, with that the pieces of staff --3 and/or 7-- in the same level as the longitudinal bars of the mat concerned are thereby arranged, so that the mat just like with the invention by welding a continuous longitudinal bar and following cutting out of pieces of staff be manufactured can, but is necessary hiebei the double number of cuts and by this additional expenditure universality eingeschränk a utilization as spacer owners according to Fig.4 of the Erf'mdung for additional armouring elements one excludes. Finally Patentschri£t Nr.449911 an insert is become known for strengthening a concrete element by Swiss, which does not exhibit any universality, but is suitable only to strengthening the upper range of a self-supporting concrete element like a concrete cover. The preference/advantage of the erf'mdungsgemäßen solution consists in contrast to this of the fact that it as Feldbewehmng, when supporting armouring is usable as shear reinforcement and that both in the even and in the bent condition of the Überlapptmgsbereich for adjustment at different widths and/or lengths of the total armouring within a certain amount is constantly changeable. By simply out bending of the boundary regions or a part of the boundary regions from the mat level behind the latter through-louse-end hand staff lets itself a stackable Baustahhnatte for a supporting armouring win, whose bent edges are usable as measuring rods. Since the bent staffs at the ends are in pairs connected by short Stabstüeke, also the possibility exists of taking up thrusts. The bent Banstahlmatten can be moved in such a way that the boundary regions overlap themselves, whereby all longitudinal bars and all transverse staffs remain in each case in the same levels. The overlap range can be constantly changed hiebei, whereby an adaptability at different widths and/or lengths is possible. An execution form is particularly favorable with that the staffs parallellau£enden to the bent edges equal far up to the bendings points does not extend, so that depending on how around the mats are pushed together, differently large cover widths are possible. For example one can, in order to achieve this goal, to leave to a side the last edge staff before the bending place of the boundary region been allotted. The invention is more near described by remark examples on the basis of seven designs. Show the Fig.1 and 2 two execution forms of welded wire meshes according to invention in a Drau£sicht, the Fig.3 and 4 in one siderespectably per two overlapped moved welded wire meshes, according to Fig.1 and the Ausflihrungsform of a Banstahlmatte according to invention further according to 2, their edges are bent, the Fig.5 and 6 in a Dran£sicht and a side view three overlapped moved welded wire meshes, the Fig.1 and 2, with bent edges and Fig.7. The Banstahlrnatte represented in Fig.1 --1-- consists of right-angled crossing staffs --2 and 3--, which are connected at the Kreuzungsstellen or a part of the Kreuzungsstellen in usual way. In the available case are also --2-- designated staffs Längsbzw. Carrying staffs and also --3-- designated staffs Querbzw. Verteihrstäbe of the mat. The mat is narrow, i.e. in form of a Mattenstrei£ens toward the longitudinal bars --2-- trained. The two opposite boundary regions --4 and 5-- are in each case into first sections --6--, in those at least two perpendicularly to the edge of mat staffs running --3-- by Stabbzw. Connecting pieces --7-- are connected, and into second sections --8-- subdivided, in which no connecting pieces are intended. In the intended coverage of the two edges, that in the available case maximally the ranges --9 and 10-- to correspond, is in each case the second section can --8-- at least around the double staff width more largely than the first section --6--. Hiedurch exists the possibility, the sections --6-- a neighbouring mat into the sections --8-- to push in, u.zw so far, until the continuous hand staffs --2-- lie side by side directly. The welded wire mesh represented in Fig.1 ends both above and down with a first section --6--. In order to be able to engage mats of the same descriptive Ausgestahung, would have this alternate around the width of the first section --6-- shifted to be arranged. This can be avoided by additional mats of the arrangement after Fig.2. The welded wire mesh --11-- after Fig.2 differs from the welded wire mesh --1-- after Fig.1 only thereby that both at the upper and at the lower end a second section --8-- is intended. Hiedurch exists the possibility, a mat --1-- and a mat --11-- without being able to engage mutual transverse shift. The same designations as selected with are in all other respects Fig.2. Those in the Fig.1 and 2 represented welded wire meshes leave themselves, there the connecting pieces --7-- in the same level as the longitudinal bars --2-- lie, extremely simply manufacture. The connecting pieces --6-- hiebei appropriately by the fact it is won that a continuous longitudinal bar is connected with the transverse staffs concerned and afterwards in the sections --8-- Pieces of staff to be cut out. The alternating distance of the Qnerstäbe does not cause any difficulties during the mat production. After Ausflihmngsformen the Fig.1 and 2 can be cut out of the same sequentially manufactured mat strip. Of course the mats can be manufactured also in detail, whereby in a case with a short, in the other case with a long transverse distance must be begun. In Fig.1 still two variation options are suggested. Both the first sections --6-- and the second sections --8-- can still additional staffs contain, also --3a and 3b-- are characteristic. The staffs --3a-- the first sections can hiebei with the connecting pieces --7-- connected its or not. In addition can in the boundary regions --4 and/or 5-- more than one connecting piece intended its. This possibility is in the designs by an additional connecting piece --7a-- suggested. Although the Banstahlrnatten already is usable in the even form represented in the Fig.1 and 2 and opens here the possibility of being able to change under Wahmng the prescribed cover width the distance of the longitudinal bars within a certain range the welded wire mesh according to invention is used particularly favourably in a form, with which from the two boundary regions of the mat behind the last passing edge staff approximately equal broad zones from the mat level are. Existing staffs --3a-- are not bent. In the Fig.1 and 2 by dash-dotted lines --12 and 13-- angedenteten bendings points are selected preferably in such a way that the bent ends of the transverse staffs --3-- as Abstandhaher r a Stützbewehmng are usable. Bending can sharpen right angle in or take place. In the Fig.3 and 4 are two welded wire meshes each moved with overlap --la and 1la-- represented, those by bending the boundary regions of the mat around 90° along the lines --12 and 13-- of in the Fig.1 and 2 represented welded wire meshes are made. For reasons of the better representation is the mat --la-- broken in each case drawn. With the Anorduung after Fig.3 is the Baustahhnatten --la and lla-- so adjacent that in each case the broad boundary region --5-- on the same side is. Hiedurch is made possible a Ineinanderschieben of the two mats from zero to a mesh width. Arbitrary intermediate positions are possible. In the represented case the two mats iiberdecken themselves approximately around half mesh width. The distance --14-- between the hand staffs of the neighbouring mats likewise about the half mesh width corresponds in this case. The armouring arrangement after Fig.4 differs from after Fig.3 thereby that the right mat --la-- around 180° turned, so that the two broad boundary regions --5-- meet. It is here an overlap up to two mesh widths possible. In this represented border line the continuous edge longitudinal bars lie --2-- the neighbouring mats directly next to each other. Mattenwie in Fig¢4 is represent-arranged, then the mats can be shifted within a range by two mesh widths mutually and be adapted to the requirements concerned. As evident from the Fig.3 and 4, both the longitudinal bars and the transverse staffs of the two mats lie in the same level, so that the static useful height can be used fully. The mats industries, since the bent edges determine the necessary distance from the training, to be only set up. The connecting pieces --7-- cause an anchorage of the bent ends of the transverse staffs, so that the bent ends can be used as Schubbewehmng. In all other respects the connecting pieces can --7-- so far arranged by the respective end of the Querstabes concerned its that they can serve at the same time as measuring rods for additional armouring elements which can be taken up. In Fig.4 is such additional Bewehmngselement in form of a staff --15-- suggested. In the Fig.5 and 6 an armouring arrangement built up from three armouring mats is represented in a plan view and a side view. The edges of the mats are only about around an angle of 70° from the mat level in this case. There is two mats ---la--- of the type of the Fig.1 and a mat ---11a--- of the type of the Fig.2 uses. In Fig.5 still two ModlBtkationen are represented. The mat ---11a--- possesses additional transverse staffs --3a--, those not with the connecting pieces --7-- are connected and when bending the edge in the mat level remain. In addition Fig.5 shows that not all first sections --6-- from the mat level to be must. In the designs is a first section --6-- the mat --la-- leave in the mat level. During with the Ausfühmngsformen the regulation according to invention described so far, in the boundary region the second sections --8-- at least around the double Stabbrcite more roughly than the first sections --6-- to make, by it is realised that in both boundary regions the first and/or second sections are assigned to the same staffs and/or wires in each case and the staffs with alternating distance run parallel to each other, is with the Ausfühmngsform after Fig.7 the first sections --6-- the second boundary region the second sections --8-- first and in reverse assigned, and run in each case to a second section --8-- boundary region of due staffs toward zn the respective first sections --6-- the other boundary region together. With other words this is called that the staffs a of the direction must be arranged alterräerend bent. In the available case there is the transverse staffs --3--. The advantage of this type of mat consists of that no two Ausführungs£ormen are necessary, in order to prevent a mutual transverse shifting of neighbouring mats. The mat lets itself manufacture in similar way as the descriptive mats and becomes preferably also along the bend lines --12 and 13-- turned. Similar armouring arrangements, as they are descriptive into the Fig.2 to 6, can be arranged.
