DE29600244U1 - Boundary stone with central perforation - Google Patents

Description

1. After the boundary points have been marked out, they are spatially fixed using three so-called alignment rods. To do this, a alignment rod is placed on the ground and the tip of a marked cone is placed on it. The position of the rod is secured using two further rods in such a way that one rod is stuck into the ground at the rear end of the lying rod (the lying rod hits the upright rod).

A third rod is also inserted into the ground with a stop in the front area of the lying rod. The lying rod can now be put to one side and the necessary hole (depth approx. 70 cm, 15 cm drainage pipe + 50 cm stone + 5 cm to cover the drainage pipe) dug to set the half hollow brick or the cone (underground protection). After digging the hole, the set-aside alignment rod is put back in its original position. In order to transfer the adjusted point on the tip of the alignment rod lying on the ground into the hole in the ground, a so-called plumb line is used.

w. The boundary point is given additional underground protection. For this purpose, an upright drainage pipe or a plastic cone is placed at the point of the plumb line. The drainage pipe is tamped down and the position is checked by plumbing again. The markings are covered with some earth. The boundary stone must now be placed centrally over the drainage pipe if possible. The cross on the boundary stone must now point exactly at the offset tip of the lying alignment rod. In all cases, the stone must now be lifted and adjusted in a crouched position until it is vertical and the cross points exactly at the tip of the alignment rod.

problem

The problem with the workflow is the high amount of time required and an unhealthy posture.

JInvention

The aim of the innovation presented here is to significantly improve the complex work processes described above. The core of the invention is a new type of boundary stone with a hole in the center (2) (exactly in the middle of the stone, from top to bottom).

First, proceed as described under point 1. However, the depth of the hole only needs to be 55 cm if you are working with a plastic cone.

The existing device for setting perforated plates for support and securing points (1) (hereinafter referred to as the guide rod/utility model application dated 27.12.1995) is inserted with the tip into the mark made by plumbing and a small hole is pre-drilled. The guide rod is pulled out again and a plastic cone is placed on its specially shaped end. The plastic cone is pressed into the ground with the help of the guide rod. This work can be carried out in an upright position. The rod remains stuck. A layer of soil approx. 5 cm thick is applied. The stone (2) can now slide over the rod and reach its exact position. This work can be carried out in an upright position. There is no need to lift the stone again. The hole is filled with soil. Finally, the hole in the boundary stone is provided with a dowel mark (boundary point). This work can only be carried out by one person.

Claims (1)

Protection claims divided into following categories ^{: 5:} .. ^: Boundary marking object with perforation. The object is characterized by -that it is cast and has a hole in it -that it is designed in such a way that the boundary marking object slides over the guide rod (1), which has previously been brought into the precise horizontal and vertical position, and thus reaches the exact position
