DE3518334A1 - Advanced-working strap for web and channel sections - Google Patents

Abstract

The innovation of the advanced-working strap described, which is shown in the drawing, consists in the fact that the two strap halves are connected to one another hinge-like and can be frictionally attached with impact hooks to the respective support section. The advanced-working strap has no loose parts due to the special construction and by shaping in the enclosing area, but otherwise in the same mode of action, can be used for the support system of web sections as well as channel sections.

Description

description

~~~~ = ~~ The front bracket used in German mining for bridge and Rinpenprofile are usually by means of screws on the respective extension attached, so that the attachment and repositioning takes a lot of time, apart from the loss of individual bolts and nuts.

The stem bracket described below has no loose parts and can be attached very quickly to the extension profile provided by means of a hook and implemented.

In Fig. 1, the complete front bracket is shown in the view.

In Fig. 2, the complete front bracket is shown in the side view.

Figure 3 shows the shape of the surrounding claws (a) for expansion from the channel profile, with otherwise the same design of the entire front bracket.

The front stirrup is composed as follows: From the 4 identically shaped Enclosing claws (a), suitable for web or channel profiles, in pairs through cross straps (b) connected, which then also serve as a support for the stem cap (c). On the 4 identically shaped Surrounding claws (a) are head bolts (d) attached to a pair of surrounding claws for swiveling attachment of the hook (e), and for hooking on the other pair the hook (e) are used.

The surrounding claws connected in pairs by transverse straps (b) (a) can be folded together at the lower end by means of hinges (f) to form a unit tied together.

The hooks (e) are on; their outermost ends towards the inside of the Angled stem bracket that allows the two pairs of UmEassungsklauenpaars to unfold Allow only so far that the entire stem bracket can be reached when the hook is in the upright position (e) can comfortably run over the respective profile.

After folding up the front bracket, the two hooks fall (e) onto the shanks of the headed studs (d) and can be hit with a hammer on the angled Part are brought into the clamping position, as well as in the opposite direction be solved again.

The individual hook (e) is designed so that when it hits on the head bolt (d) against the play of the two halves of the bow Has to overcome the slope in order to then spring back into a rounded position in the end position.

Claims (1)

Protection claims Stem bracket to accommodate the pre-pledging cap (c) characterized in that the two stem bracket halves, consisting of parts (a) and (b), hingedly connected to form a unit by a hinge-like connection (f) is and therefore quickly attached to the respective one by unfolding or collapsing Extension profile can be attached and also removed. Front bracket for receiving the pre-pledging cap (c) characterized in that that this by the two hook (e) positively and quickly on the can be attached to the respective extension profile. Front bracket for receiving the pre-pledging cap (c) characterized in that that the two halves of the stem are bent through the angled hooks (e) Only let it unfold enough to comfortably cover the entire stem bar to be able to manage the respective expansion profile. Front bracket for receiving the pre-pledging cap (c) characterized in that that this with the same mode of action, only changed in the surround, for all web and gutter support profiles can be used.
