Definitions
- the invention relates to a ladder for accessing manholes, in particular of sewage shafts, with two vertical, parallel to each other Spars and a variety of tread elements that are inseparable from the spars are attached, as well as with fasteners for attaching the ladder to the Shaft wall.
- brackets are known for example from DE 297 15 681 U1. adversely on these brackets is in particular the high required for the attachment Installation effort. For each bracket, two holes must be made to measure be brought into the shaft wall.
- the invention has for its object to provide a shaft ladder, which the Deposition of fibrous material prevents a comfortable and safe Inspection of the shaft enables and only a small assembly effort requires.
- the task is performed by a head of the aforementioned Type solved, in which the tread elements are U-shaped and of the protrude into the cross-section of the shaft against the uprights on the shaft wall.
- the decisive advantage of the shaft ladder according to the invention is that Avoiding intersection points lying in the shaft cross section between horizontal and vertical parts of the ladder and the resulting small number Possibility of fibrous deposits on the ladder. Should fibrous parts nevertheless deposit on the ladder, these are essentially of the linear unbranched contour of the conductor easy to remove.
- the individual tread elements of the ladder according to the invention can both be made of Pipe material, as well as solid material. Does the material have a sufficient strength, the use of pipe material is recommended, since this is easier to bend in the course of processing, the procurement is usually cheaper and handling due to the weight saving is simplified. When using non-corrosion resistant It is better to work with solid materials, especially with Presence of aggressive media which ensures strength.
- the ladder according to the invention made of V4a material manufacture. Additional corrosion protection is advantageously dispensed with.
- U-shaped tread elements have a round cross section. They should also be U-shaped trained tread elements be designed such that the two legs the U shape to the section between the legs from the by the of protrude the horizontal plane defined between the two legs and thus protection against lateral sliding off the tread elements form. Such a design of the tread elements wins especially in view to the mostly damp, friction-reducing environment in canals.
- the risk of a dangerous slipping off the ladder according to the invention is advantageously reduced in that the tread elements on their footprint are provided with surveys.
- These bumps can shape of spherical pimples, or expedient in the manner of a Tear plate can be formed.
- the execution of these projections should be both prevent sideways and frontal sliding off the tread elements.
- the manufacturing cost of a ladder according to the invention is reduced if the Tread elements consist essentially of bent tubes.
- the material used after the bend has insufficient strength properties have, is a design of the tread elements from pipe bends and straight pipe sections that are welded together are preferable.
- the conductor is provided with the reference number 1.
- the ladder 1 consists essentially of two vertical bars 2 and one Large number of individual welded to the two vertical bars 2 Step elements 3.
- the ladder 1 is at certain vertical intervals by means of fasteners 4 attached to the shaft wall 5.
- the tread elements 3 are U-shaped when viewed vertically, the section 6 between the two legs 7 of the U-shape so bent is that a lateral sliding from the tread elements 3 avoided becomes.
- the round cross section of the tread elements 3 enables a comfortable one Hold on during the inspection.
- the individual tread elements 3 are welded to the vertical bars 2. All components are rustproof due to their design in V4A material.
- the section 6 between the two legs 7 of the U-shape is used on the Top side as contact area 8 and is there with nub-like elevations 9 Mistake.
