DE7824430U1 - RAILING BRACKET FOR BARRIER PURPOSES ON CONSTRUCTION SITES - Google Patents

Description

The invention relates to a detachable "eft handrail holder," in particular for building construction, Can be screwed into a built-in part provided with a nut thread and embedded in the (floor) floor.

Consists of a railing post and at least one to hold a plank or the like. Suitable hook and a screw-in pin.

In building construction, e.g. Sometimes also in civil engineering, it is necessary to secure the job-1 me to put in a makeshift railing. It mostly consists of a handrail holder with inlaid planks (see Dt PS 1181390). The railing brackets are here either attached to steel profiles, beams, etc. or in a recess in the floor Built-in part, such as an eye socket, anchoring sleeve system ROBUSTA or the like. screwed. The previous constructions had firmly welded hooks for receiving the planks, only for attaching the so-called floor board are attached to sleeves, hooks axially displaceable to the post known CDt AS 1233565).

Since in the versions to be screwed in, the nut or screw thread is their In each case, the first thread turn, as a rule, from railing holder to railing holder different position - otherwise you would have when attaching (welding) the threaded pin and when installing the eyelet sleeves strictly at the beginning of the 1st thread turn have to pay attention - the railing brackets could not be screwed frictionally will. A force-fit screw connection with the previous construction ^ n would have the consequence that the hooks from handrail holder to handrail holder in different Would show directions and inserting planks would be impossible. The previous Railing brackets received their anti-rotation lock from the plank composite from Railing holder to railing holder, - an unsatisfactory solution.

The invention was based on the object of frictionally screwable handrail holders to accomplish.

The object was achieved according to the invention in that the upwardly directed Hooks are mounted on a sleeve freely rotatable around the post.

This design has the advantage that the hooks are rotated into the desired position regardless of the screwing-in end position of the railing bracket

can.

In a further embodiment of the invention are either at the top of the post or at least two parallel to each other arranged above the screw-in pin Areas so that a wrench can be attached.

This enables the handrail holder to be mounted in a non-positive manner.

An exemplary embodiment is shown below in schematic drawings.

Fig. 6 corresponds to Fig. 5 with the special feature that the post (1 ^ς ) is centered and welded on via the centering collar.

Claims (4)

Protection claims: 1.) Detachable railing holder, especially for building construction and bridge construction, can be screwed in into a built-in part with a nut thread and embedded in the (floor) floor, consisting of a railing post and at least one, to accommodate a plank or de ^ gl. suitable hook and a screw-in spigot, characterized in that the upwardly directed hooks are mounted on a sleeve freely rotatable about the post. 2.) Railing holder according to claim 1, characterized in that the screw-in end a screw head, with at least two parallel surfaces, coaxial to the main axis of the railing bracket and a minimum distance equal to or is larger than the outside diameter of the post. 3.) Railing holder according to claim 1, characterized in that the screw-in end a cylinder-free or slightly tapered collar, its largest diameter is smaller than the inner diameter of the post. j 4.) Railing holder according to claim 1 and / or 2, ) characterized in that the post at its j upper end as a screw head, consisting of at least two parallel] Surfaces, is formed coaxially to the main axis of the railing holder; 7824430 01/25/79
