DE7107224U - DOUBLE REINFORCEMENT SPACERS MADE OF WIRE, IN PARTICULAR FOR VERTICAL DOUBLE STRUCTURAL STEEL MATS - Google Patents

Description

The pattern concerns a D; pe I reinforcement spacers made of wire, in particular for vertical Doppei-Laustar.lmailen, consisting of a piece of wire with a Middle section and two end sections, one of which is hook-shaped and on the one welded wire mesh or the like. hookable is bent back and the other is either also hook-shaped and on the other welded wire mesh or the like. bent back to attach or only to the bend on the welded wire mesh or the like. is provided.

Such double mat spacers made of wire are known. They are used to to keep two vertical mats at a mutual distance. In order to keep the mats at a certain distance from an outer formwork hold, special spacers are used.

In order to reduce this effort, double mat spacers with a comparable effect were created from a sheet metal strip, at the ends of each

three adjacent tabs are punched out, two of which as

The mat hooks are bent back and act as a spacer.

an outer reinforcement extends further. This design requires a different I

relatively large width of the sheet metal strip. This has the disadvantage that '

If installed horizontally, there is a risk of a moderately wide double mat spacer unfilled cavities in the reton form.

The pattern is based on the task of creating a double reinforcement spacer that has the advantages of the aforementioned double I mat spacer made of sheet metal, namely the additional function as a spacer!

holder between at least one of the Bäusrah! matt G.dg !, and a form, but the drawback mentioned the danger of cavitation avoids υ nd it easy and material-saving manufacture and easy dismantling, installation is * bar. I j

To solve this problem, the aforementioned double mat - ¹

Spacer made of wire assumed that it is the same in all directions has a small wire cross-section, so that it is independent of whether it is connected to vertical or horizontal bars of the welded wire mesh;

can be enclosed equally well by concrete. Based on this ). ·

Design, the pattern is characterized in that at least one of the mentioned End sections behind his mat hook is bent back again to a again running approximately parallel to the middle section outwards Section which, in the manner known per se, acts as a spacer to an outer formwork to beyond the mat hook addition extends.

Such a repeated turn is easy to make and needs little additional materia !. The risk of hollow spaces under the spacer

create space is no longer available. The one to the outer formwork ei »Mccker.de Absic; r.dhwUereb; ehr: i; i Is just as strong and 'obus? «**? Mr Middle section of the whole spacer, while in the known sheet metal construction, the outer spacer is much weaker.

In a further significant improvement, the pattern is characterized by a movable locking part mounted at the end, which or the like after hanging on the welded wire mesh. is movable in the locked position and closes the mattress hook. Appropriately is such a. ^r folders like movable, preferably in locks by gravity. pbar.

In a preferred embodiment, the locking part is mounted on the bsrarvlhalterobschnitt. The standard double mat spacer is then connected to the two reinforcement mats, etc. in such a way that the spacer sections lie over the mat hooks, after which the metal locking flaps are folded down and the entire spacer is attached the welded wire mesh is locked. This is much faster than attaching the Ub-Üche with a thin wire.

Further details and advantages of the pattern emerge from the following Description of exemplary embodiments shown schematically in the drawing. Show in the drawing

Fig. 1 in perspective two different types of embodiment, ange

connected to two vertical wire meshes and 2 and 3 the two types of embodiment according to FIG. 1 in side view.

Sr. Fig. 1, two welded wire meshes 1 and 2 are shown, which are perpendicular and stand parallel to one another at a distance and by means of spacers according to the pattern one below the other and on each side opposite an outer formwork turn held at a distance. The construction steel mats 1 and 2 consist of horizontal bars ^ and vertical bars 4.

Each spacer (Fig. 2 and 3) has a central section 5 and two Endobschnitte 6, each to one on a wooyiechien or perpendicular Rod 3 or 4 of the welded wire mesh 1 or 2 hooks 7 are bent back. The outer hook section runs, as the drawing .shows, a little bit parallel to the middle section S inwards and is then bent back again to a pattern that runs outwards again Section 8, which extends as a spacer to an outer formwork 9 or 10, indicated by dash-dotted lines in FIGS. 2 and 3, to beyond the mat hook 7. A plastic cap 11 is placed on its end in the usual way.

The second bend back forms an outwardly open hook 12. D'eser can be of a width that it also forms a mat hanging hook, the bottom of which to the bottom of the first mat hanging hook 7 in the direction of the Mittelobschnitts 5 is offset, so that different distances between the two welded wire mesh 1,2 can be set up with the same spacer, or it has such a small width that it prevents it from hanging on a reinforcement mat, so that the spacer inevitably only has its hook 7 on the reinforcement mats can be hung and inevitably only this one Distance between the two mats is established. With a wire loop the suspended position of the spacer is secured.

In the embodiment according to FIG. 3, a spacer section 8 is on Flap-like movable locking part 14 mounted, which in the exemplary embodiment consists of a metal tire with a bent bearing eye and is pushed onto the section 8 before the respective plastic cap 11 is placed.

This embodiment is hung on horizontal bars 3 of the reinforcement mat, in such a way that the spacer section 8 lies above the mat hook 7, as shown in FIGS. 1 and 3. After introducing the

710722 k Wed. 71

Stöbe 3, the locking part 14 is folded down as far as that shown in FIG. 1 or position indicated by dash-dotted lines in FIG. 3. So that's the Moth hook 7 closed. The second bend back holds the locking part 14 against slipping in the direction of the central section 5.

In the manner according to the pattern, only one end of the spacer can also be used be formed if only a ^ spacer section towards this side desired between the respective welded wire mesh and the outer formwork will. The other end can then only have a simple hanging hook 7 or around a corresponding one in the manner described at the beginning Piece should be extended straight, then only after attaching to the other Welded wire mesh is bent over.

The spacer age according to the pattern can of course also be used for other double reinforcements use, e.g. if a welded wire mesh is at a certain distance from other reinforcing bars and at the same time from an external formwork should be held. Furthermore, the spacer can also be used for horizontal double reinforcement, if in another way, e.g. by means of a trestle designed other spacers, it is ensured that the upper reinforcement is supported in a non-slip manner parallel to the level of the lower reinforcement. as However, the spacer according to the pattern has proven to be particularly advantageous in the case of vertical Double welded wire mesh reinforcement has been proven.
