The technical field

The invention relates to a method of alignment of the telescopic vertical pipe that has an outer tube and movable within the outer tube inner tube with top and/or base end side.

Such telescopic vertical pipes are used to set the binder ceiling, supporting scaffolding or platforms. Vertical pipes are also known as building supports and are used, for example, for formwork, as pipes for scaffolding as part of the so-called modular forests (spatial load-bearing structures) or as constituent parts of the vertical frame in frame designs for facades. Regardless of the purpose they should be adjustable in height, in the construction of frames often need to be adjusted to a vertical pipe or educated them vertical frame to form the basis - for example, to the inclined floor or stair steps. When installing a ceiling construction of the base must have a certain predetermined height. Therefore, the telescopic vertical pipes have an outer tube and an inner tube, which is to change the length or height of movable along the length of the external tube can be locked and thus is telescopic. This sets the height can be produced by step the th or stepless movement of the inner pipe, for example, with pins inserted into the through-hole or via screw threads.

To increase the area of support these vertical pipes are on the front side, on one or both free ends, a transverse plate or base. It serves to increase the area of support to less significant contact pressure was exerted on the mating surface such as floor, ceiling or wall. Without plate-base vertical pipe was pressed if the load into the ground or could occur sediment under the load.

Already installed telescopic construction of piers or vertical pipes often have to align in a vertical position. This is done, for example, when the binder of the ceiling, if construction support are already under the influence of a load, for example, by lying on the binder ceiling. Move construction bearing is under load, it is difficult, in particular, where the base often has a rough surface, such as raw concrete ceiling with small stones and sand, which increases the friction. The alignment in the vertical position requires the application of large forces, usually with the use of many aimed blows with a hammer on the area close to the top or base of the vertical pipe. This leads to undesired hair is a diversified damage. As a result of damage to the surfaces of the pipes in this area quickly corrode or change of geometrical parameters adversely affect the ability of the telescopic pull-out and/or on the carrying capacity. Therefore, it was proposed to provide the outer tube such supports shock resistant device. It takes the blows and prevents damage to the pipe. However, shock resistant devices require additional consumption of materials and labor required for their production, and because of their shock absorbing actions lead to the need for more powerful strikes from the user.

Disclosure of inventions

Therefore, the objective of this invention to provide improved alignment of the telescopic vertical pipe with the top and/or base end sides.

This problem is solved by a method of alignment of the telescopic vertical pipe with signs of paragraph 1 of the claims. Preferred embodiments of the invention are subject of the dependent claims.

According to the invention it is proposed to provide top or bottom on the edge of the slots to them, between the plate tops or bases and related surface, inserted a lever tool. Through linkage tool creates ratios are the HT gain, which allows you to move the vertical pipe along the mating surfaces even on very bad rolling basis. Unlike shock protective device according to the prior art notches on the edges is performed without additional consumption of raw materials and with little effort in the production of, for example, through a proven process operations used in the manufacture and attachment of the tops or bottoms. When the lever movement of the pipes can be carried out very strictly metered, without loading material and noise associated with the blows of the hammer. "Notches on the edges" here does not mean that they can only be on the edge. The notches, of course, can also occur inside. The most important is that the edge of the at least provides the opportunity to find suitable spots for the lever tool.

Under telescopic vertical pipe means it has an outer tube and an inner tube movable within the outer for height adjustment, and the inner pipe is made with stepwise or stepless be moved and fixed in different positions and thus is telescopic. This height adjustment and fixation can be accomplished by manual movement inside is her pipe - for example, with pins inserted into the through hole. It is also possible stepless height adjustment with locking, for example, due to the presence of inner tube outer thread, which is held with the possibility of screwing in a corresponding screw thread or nut and the screw thread or nut rests on the outer pipe. Therefore, the inner tube to freely slide in a vertical pipe and is connected with the other parts, for example, with base plate, having a thread. Vertical pipe can be embedded also in a horizontal position, for example, between walls, or the walls of the casing, which also falls under the scope of the inventive concept. In this case, under the concept of "vertical pipe" fall within any building support, in particular telescopic.

If the inner tube is used the rod, it may simply be freely inserted deep enough in the outer pipe, a vertical pipe perceived only the pressure force in the axial direction. Pressure forces are perceived screwed on the rod by a nut or, in its most General form, a screw thread, which in turn relies on the hole of the outer tube or, in General, on the outside of the pipe. Further, the stud and nut are such that even at maximum extent unscrewing the rod he held is it deep enough in the outer pipe. The nut preferably has a lamb for her without turning tool. The rod can be inserted in the upper or in the lower end of the vertical pipe and thus to form a rod-a rod or rod-based. This rod preferably includes a top or bottom, a pipe with a screw thread and nut rod. These threaded rods are inserted, for example, also in vertical racks modular scaffolding or in a vertical pipe exterior or load-bearing forests.

The notches in the plates preferably designed in such a way that, through the impact of the lever overcomes the static friction between the installation surface and related surface at the site and there is a sliding friction, which creates less resistance. Therefore, specialists choose the height and the depth of the recess so that it is possible to use conventional, used on-site linkage tools, for example, the puller, so that by influencing lever tool mating surface with a corresponding movement of the lever is sufficiently large lateral shear. If the groove is too flat, then lever the tool cannot be applied to or will create too small a force in the lateral direction. If the groove is too high, the degree of hcpa is istia lever is reduced. If the groove is too deep, that is too far inland, towards the pole, lever tool, under certain conditions, will be inserted too deeply and will create essentially only vertically directed force, and not the desired lateral force. If the groove is not deep enough, the impact lever will not create almost vertical efforts, and will happen - if it occurs at all - only a very short movement to the side. After that, staff will again be actuated lever tool, and quite often.

In the embodiment provided by this embodiment of dredging, under the action of the inserted them in lever tool separates tops or bases from the mating surface. As a result, the contact area is reduced, and installed between the site and the adjacent surface occurs sliding friction, for alignment requires less power.

Preferably both the above-mentioned force action of the lever, namely the separation of the tops or bases from the mating surface that reduces friction, and the application of shear forces acting in the lateral direction, are produced simultaneously, only the rotary movement of the lever. At the site of contact between the outer edge of the recess and the lever when the impacts is under the lever, a force, the vector which is directed from the mating surface to the vertical longitudinal axis of the pipe.

Named in the claims sizes recommended for vertical pipes to the tops or bases and for excavation showed themselves to be particularly suitable for the conditions of construction and convenient for the user.

Vertical pipe preferably is an integral part of the scaffold, such as pipes for scaffolding or as one of the vertical columns in the frame for forests. In Rama to the forest in two parallel spaced vertical pipes in the lower and in the upper regions of the outer tube are connected to each other by a horizontal carriers, forming a frame. The so-called modular forests are connected preferably by means of prefabricated system components and have appropriate opportunities for articulation. This can be, for example, a system with plates for joints in vertical pin-neck and V-heads on the struts and diagonals for hanging them on a plate. Alternatively, it may represent a system with prefabricated frames, which by means of struts and diagonals are fastened to each other and form a rigid connection.

The vertical pipe is used preferably for formwork or to supports, for example,as a building support. Pipe or bearing used in upside down position, so the concept of "above" and "below", "top" and "bottom" as appropriate interchangeable in meaning and are not restrictive.

A short comment to the figures of drawings

Further advantages can be seen from the following description and the accompanying drawing. Exactly the same characteristics mentioned above and below can be used according to the invention, respectively, individually or in any combinations with one another.

The mentioned types of exercise should not be seen as a complete list, and have the nature of examples. It is shown:

Figures 1A, 1b: telescopic vertical pipe in the axonometric image;

Figure 2: area of the legs of the vertical pipe according to the invention in axonometric image, and

Figure 3: an implementation option tops or bases without a piece of pipe in the form of technical drawing.

The implementation of the invention

Figure 1A shows a telescopic vertical pipe 1 with a round outer tube 2 and move it round the inner tube 3, which is made here in the form of a threaded rod. Thus, the rod 3 is inserted in the outer pipe 2, and the height adjustment is infinitely variable, in this thread operetten outer pipe at the top of the outer tube 2 by means of suitably formed concretely carved in the form of a nut 21, 5, rotated manually. That is, the outer tube 2 carries a nut 21 screwed with it the rod 3.

Terminal 3, which serves here only as an example of the internal pipe in the construction of the telescoping vertical tube has at its free end, in this case at the upper end 31 of the top 4, essentially square - here with 10 rounded corners. The same applies to the lower free end 41 of the outer tube 2. Tops or bases 4 are according to the invention accessories for alignment in the form of grooves 42, which are explained in more detail. The pipe 1 can be installed as back end, for example, as a support leg for forests and rough terrain.

Figure 1b shows another variant of the construction of a support 1, which differs from figa only the principle of its fastening 21. This adjustment in height is effected by manual movement of the inner tube with the fingers inserted in one straight line through holes in the inner tube and the outer tube. Thus is rough height adjustment. For fine adjustment is provided by a continuous movement by screw threads, as in figure 1A, which, however, occurs only here for a certain period, in order pokr is that they area between the two apertures. Here a screw thread is provided only on a short section of the outer tube 2, which is more economical and less time-consuming to manufacture.

In the figure 2 as an example of a detail showing the base 4 according to the invention, all of the comments, of course, also belong to the appropriate topping. At the lower end 21 of the outer tube 3 is attached to the base 4 according to the invention, which produces, as a rule, by inserting the end of the pipe 21 in the circular recess of the workpiece base 4, or by draping the end 21 of the pipe billet base 4 around this round cutting with subsequent welding spot welding or seam welding.

The base 4 by material and size corresponds to the commonly used bases. In all four side edges 43 a square or rectangular base made of notches 42. They are only in the middle pane edges 43, in order to be able to work in the field of notches 42 great efforts, without giving effect to the deformation of the base 4. The recess 42 is done by processing the base, for example, by stamping. However, preferably it is about the arcuate segment.

For reasons of stability of the treated area edge 43 is only 30 to 60%, preferably from 35 to 45% of the entire length of the edges.

Treated area, which forms the recess 42 is in terms of the Orme arc, and curved lines form with the outer edge 43 of the base 4, the angle is less than 65°, preferably less than 45°. This exercise promotes longevity and prevents gaps in the edges 43 of the recess 42.

The base may be round, passing around the circumference of the recess. Then the lever can be used at any place, and thus has the ability to produce a shift in any direction. Theoretically it would be enough and only three slots, distributed at intervals of 120°. Similarly, it is also possible, and a greater number of notches. However, it is preferred that four grooves, distributed with an interval of 90°, as they correspond to the usual representation in straight angles and provide high durability edge against her curl up. This is true regardless of the geometry of the base.

Finally, figure 3 is a technical drawing of the Foundation according to the invention with a fixed sample size in millimeters.
