ATd withstands high reinforcement layers in concrete structures or the like

The invention "relates to a spacer which is used for elevated reinforcement inserts in concrete structures or the like and which consists of a more" be inigen wire frame, which is supported on this with its legs spread out towards the formwork
having defense deposits.

Legs on this and a support for the loading

The known spacers of the aforementioned type have the disadvantage that their legs are under greater load bend or spread excessively. This is especially the case when the reinforcement falls before or during the concrete pouring are committed by the construction workers, the spacers experience such a pressure that bending or spreading of the support legs or even: breaking off the legs, especially at the welding points, he follows. .-- ■. -. - ".-" - ■ -

Since for reasons of static security the constant Distance between the. Reinforcing iron and the formwork

. must be strictly adhered to, the object of the invention is to create a spacer "! even if the specified defects ^J do not occur and which is characterized by high! puncture reliability and stability. ■

The object is semäß solved with the invention in that the support legs of the ex withstanding he transit s _e: inen 'via inlet "' donating, directed parallel to the formwork clamp are fixed in position to a further feature of the invention is the clamping bracket from a.. One-piece wire formed and has essentially the shape of an equilateral polygon (triangle or square) with rounded. ''Corners, the free ends of the wire are bent in the plane of the bracket to opposite sides so that they together form the last corner of the polygon or the polygon. It is also provided that the free ends of the clamping bracket form - - Twisted, cross springy before pushing it over the spacer, whereby the support leg located at this point .being "caught" when the clamping bracket is pushed on, and the clamping bracket is secured against sliding off. This ensures that the required The distance between the formwork and the reinforcement inserts remains constant, even if the latter is subjected to additional stress.

Pig. 4 shows a modified embodiment of the clamping bracket on a reduced scale.

The in the I ¹ Ig. The spacer shown in 1 and 2 consists of the three-legged wire frame 4, which is supported with its legs 5, -6 and 7 on the formwork 8. The: Support legs 5 * 6 and 7 are supported by a push-over, ps.-. .Rallel to the formwork 8 directed clamping bracket 9 fixed in position. The clamping bracket 9 is formed from a one-piece wire 10 and essentially has the shape of an equilateral triangle with rounded corners. The free ends 12 * 13 of the wire 10 are bent in the plane of the bracket to opposite sides such that they together form the third angle 11 or close the triangle. Furthermore, the free ends 12, 13 of the wire 10 forming the clamping bracket 9 should cross resiliently before being pushed onto the wire frame 4 (Figure 3). The spring or no.

Clamping effect of the bracket 9 is achieved in that the
Angle legs 14, 15 are bent to less than 60 ° in their starting position. When the clamping bracket 9 is pushed onto the wire frame 4, which has an approximately frustoconical shape, the contact points 16, 17 and 18 slide on
along the support legs 5, 6 and 7 until the flexible ends of the free wire ends 12 and 13 unite to form a rounded angle 11. The clamping bracket 9 is now sitting parallel to the formwork 8 firmly on the wire frame 4 aufj whereby the; Support legs of the latter are held in place.
Since the entire spacer is made of corrugated. Wire (like
for welded wire mesh), the clamping bracket 9 cannot slide up. ·. ... '_ ■ \

While in the Pig. 1 to 3 a three-legged spacer is shown, shows]? ig »4 a clamping bracket 9 ″ for a four-legged spacer with the wire legs 14 'and 15' cross resiliently.
