Definitions

• the present invention relates to a teaching for edge adjustment of composite stones.
• the problem regularly arises that the composite stone paving must be brought up to a wall, a house wall or a curb.
• the composite stones have a shape that allows a positive connection of several stones to form a composite. Often the stones have seen side indentations and bulges in the floor plan, so that they can be strung together like a puzzle.
• composite stones with square, rectangular, trapezoidal and other geometric basic shapes as well as with combinations of these shapes are also common.
• Those starting stones are usually started along a first side of the pavement, which has a straight alignment. Then it is connected to these stones and the composite stone surface starvation continues in all directions away from this first escape.
• the other edges of the paving are now mostly given by walls, walls, curbs and the like. These limits rarely run exactly at right angles to the first flight, so it is inevitable to adjust the edge stones there.
• the paving is deliberately placed at an oblique angle to the boundary lines in order to achieve a special visual effect.
• each one has to be cut or cut individually. For this purpose, the gap to be filled is measured with the meter, whereby the distance from two fixed reference points on the stone penultimate to the boundary line to the boundary line itself is usually measured.
• This mass is then transferred to the stone to be used, after which the desired dividing line can be drawn as a connection between the two measuring points on the stone.
• the individual stone is then cut or cut along this dividing line.
• Milling machines with diamond milling blades are used for cutting, there are special devices for hewing, by means of which the stone with its part to be used is clamped in and then cut in half by two impact axes. These hatchets hit the stone simultaneously from both sides, i.e. from below and from above, which results in a defined break line along the dividing line.
• the more precise separation is undoubtedly achieved by milling. But the cleanest cut is of no use if the dividing line has been marked inaccurately.
• the problem is here in the measurement of the dividing line, which, as I said, has to be carried out again for each edge-closing stone and transferred to the stone, which not least means time-consuming work.
• the object of the present invention is therefore to create a means which facilitates the exact determination and designation of the required dividing line on the composite stone to be adapted and which at the same time makes it easier and faster than with the previous method.
• FIG. 1 shows a teaching according to the invention in a perspective top view
• Figure 2 shows the teaching of Figure 1 in a perspective view from below;
• Figure 3 shows the teaching of Figure 1 in the use position
• Figure 4 shows a teaching according to the invention with exchangeable support plate for the first stop bar.
• Figure 1 shows all the features of the teaching according to the invention. It has two stop bars 1, 2. these stop bars 1, 2 are indirectly connected to one another via two parallelogram legs 3, 4.
• the stop bar 2 is formed by an angle profile, one leg 10 of which forms the actual stop surface with its outside, while the parallelogram legs 3, 4 are articulated on its other leg 11.
• the parallelogram leg 4 is longitudinally adjustable by having a slot 5 through which a threaded bolt 6 with a locking screw 7 leads.
• the first stop bar 1 is attached to the underside of a base plate 8.
• the base plate 8 is provided with a handle 9 on its upper side.
• the same teaching is shown diagonally from below in FIG. 2, so that the first stop bar 1 can be seen.
• This is designed as a double bar and has a zigzag shape so that it can be attached to a corresponding composite stone with a positive fit.
• the teaching shown here is therefore designed for a very specific type of composite stone.
• One bar 14 of this double bar is intended to be struck on the penultimate stone of the edge finish, while the other bar 15 is designed to be struck on the edge finish stone to be adjusted.
• the teaching is held by means of the handle 9.
• the second stop bar 2 is then extended into the position shown, in which it strikes the wall which forms the boundary line 12.
• the distance from the stone 13 to the wall can be bridged and adjusted due to the pivotability of the stop bar 2 around the parallelogram leg 3, while the angle between the direction of escape of the wall and the first stop bar 1 can be adjusted by means of the adjustability of the length of the parallelogram leg 4.
• the locking screw 7 is tightened with the right hand, so that the second stop bar 2 is fixed in a firmly defined position with respect to the first 1.
• the locking screw 7 can be provided with a special handle, which facilitates its operation.
• any stone serving as a reference stone for the stone 13 and the stone to be adapted is placed under the second stop side 2 and then pushed from there against the first stop bar 1 or the stop bar 15 until he strikes it.
• the stop surface of the bar 15 is at a certain distance from that of the bar 14. This distance corresponds to the distance formed by the butt joint between the laid stones. After the stones have been laid, these butt joints are filled with a stand by wiping them in.
• a line can now be drawn with a pencil or a chalk along the second stop bar 2, which then designates the required dividing line. The separation of the stone along this The line then takes place as usual using a diamond milling saw or using a separating device with hammer axes.
• the first stop bar which must be shaped according to the type of stone to be laid, can be attached to a support plate 16 instead of on the underside of the base plate 8, as in FIG 4 is shown.
• the carrier plate 16 with the corresponding first stop bar 1 can then be plugged or pushed onto the base plate 8.
• Different support plates 16, each with differently shaped first stop strips 1, can then be used for the different types of stone to be laid, which can be plugged onto the base plate of the gauge as required.
• the teaching according to the invention allows a previously unattainable precision in the cutting of the edge stones of a composite stone paving. Thanks to its simple handling, it enables the required dividing line to be determined precisely on the stones to be adjusted. The teaching also saves a significant amount of time compared to the time required for the conventional determination and designation of the dividing lines. It therefore considerably facilitates the creation of the edge finishes of such paving.
