Description

The invention relates to a construction clamp made of metal, in particular steel, for lightning protection on metal or steel constructions or similar building or structural parts for fastening metallic conductors on or along steel structural parts, consisting of an approximately U-shaped molded part, in particular stamped and bent part a trained in the legs of the molding, directed transversely to the U-shape of the molding, U-shaped mouth for receiving the metallic conductors, wherein the base of the U-shaped molding forms the first leg of the U-shaped mouth and is penetrated by a clamping screw , By means of which arranged in the mouth metallic conductors are acted upon by a arranged at the end of the clamping screw clamp body with pressure or applied and thus clamped or clamped against the second leg of the U-shaped mouth.

Such metal structural clamps are known in the prior art and serve to protect against damage to buildings or parts of buildings by lightning currents. The construction clamps are fixed to steel structures of the building by means of clamping screws and connected with appropriate arresters of lightning protection system, which may consist of, for example, round conductors or flat conductors, in order to divert the lightning currents through these conductors into the ground can.

For this purpose, various design clamps are known in the prior art. For example, from the DE 200 11 615 U1 a construction clamp of a similar type is known, in which a molding on an edge of a metal structural part attachable and attachable, which also has elsewhere in the molding a hole that can accommodate a connected to a conductor clamp body.

In this case, the lightning currents to be derived are taken up at a first point of the molded part, then passed through the molded part and discharged through the conductor connected to the molded part, for example, into the ground.

Based on this prior art, the present invention seeks to provide a construction clamp of the type mentioned, in which the metallic conductors are adjacent to each other and thus contact each other, which allows both the connection of the second round conductor and a circular conductor and a flat conductor which also allows both a parallel arrangement of the contacting conductors as well as an orthogonal arrangement of the contacting conductors, which is inexpensive and easy to manufacture and has a long service life.

To solve this problem, the invention proposes that the clamping body is formed part-circular and from a first position in which the clamping body is guided at least partially between the legs of the U-shaped molding, in a further position in which the clamping body transversely to the first Position is arranged and guided along the base of the U-shaped mouth, is adjustable or adjusted.

In such a construction clamp, both two round metallic conductors arranged in parallel with each other as well as a round metallic conductor and a flat metallic conductor can be clamped together. In this case, the metallic conductors contact each other directly so that the lightning current to be dissipated does not have to be routed first through parts of the design clamp to be dissipated by a separate metallic conductor, but through direct contact with the second metallic conductor connected to the earth conductor End conductor forms, can be removed.

In addition, such a construction clamp allows both the parallel arrangement of two metallic conductors to be clamped to one another and the orthogonal arrangement of two metallic conductors. Thus, for example, a first conductor consist of a part of a reinforcing mat in concrete, which can be connected to each other in a quick and simple manner by means of a construction clamp according to the invention with a leading into the ground second metal arrester by jamming.

For example, conditions imposed by a Lightning Protection Ordinance, which may require a connection of building structures made of metal with earth conductors at a distance of not more than 2 m, can thus be met in a quick and simple manner.

In addition, such a construction clamp according to the invention is inexpensive and easy to manufacture and has a long service life. Also, such a construction clamp is extremely easy to handle and requires the jamming of two metallic conductors only, for example, a commercial wrench and thus no expensive special tool, and can be mounted within a very short time.

It can be particularly preferably provided that the length of the part-circular clamping body is greater than the width.

Furthermore, it can be particularly preferred that the base of the U-shaped mouth has a groove-like recess arranged at or close to the second limb of the U-shaped mouth, within which parts of the part-circular clamping body move from the first position to the second position during adjustment back from the second position to the first position, are arranged.

As a result, the clamping body in the region of the groove-like recess, which is formed in the base of the U-shaped mouth, rotatable, so that can be adapted by the partial circular formation of the clamping body to each clamped metallic conductor. In particular, the use of only one construction clamp for both the parallel Aneinanderklemmung of metallic conductors and for the orthogonal Aneinanderklemmung metallic conductors is hereby also usable. For this purpose, only the part-circular clamping body in the region of the groove-like recess must be rotated by about 90 °, so that the clamping body from the position in which two metallic conductors are clamped parallel to each other in the position in which two metallic conductors are clamped together in an orthogonal position , is displaced.

Thus, this also reduces the number of different parts to be kept by the installer for jamming to only one part both in a parallel position and in an orthogonal position of second metallic conductors.

In addition, it can be particularly preferably provided that in the second legs of the U-shaped mouth, a further groove-like recess is formed.

By arranging a further groove-like recess in the second legs of the U-shaped mouth, for example, there inserted and clamped to round leader in a quick and easy way prepositioned.

In addition, the groove-like recess in the base of the U-shaped jaw in addition to the possibility of adjusting the clamp body also form a Vorfixierung or pre-positioning for there placed on the second leg of the U-shaped mouth flat metallic conductor. Also, this is thereby pre-positioned in the correct position in a quick and simple manner and can then be clamped by tightening the clamping screw, which presses the clamp body against the second metallic conductor.

An embodiment of the invention is illustrated in the drawings and described in more detail below.

It shows:

6 a further application example of a construction clamp according to the invention with flat conductor and thus parallel jammed round conductor;

7 a further application example of the construction clamp according to the invention with two mutually parallel, jammed round conductors;

8th a further application example of the construction clamp according to the invention with two orthogonally arranged, jammed round conductors.

In the figures, a construction clamp made of metal, in the embodiment of steel, for lightning protection on metal or steel structures or similar building or construction parts is shown. The construction clamp is used for fastening metallic conductors 2 . 2a . 3 on or along steel structure parts, in particular on reinforcing mats in concrete construction.

The construction clamp consists of an approximately U-shaped molding 1 , which is produced in the embodiment as a stamped and bent part. In the thighs 4 . 5 of the molding 1 is an approximately transverse to the U-shape of the molding 1 directed, U-shaped mouth 6 for receiving the metallic conductors 2 . 2a . 3 educated. This forms the basis 7 of the U-shaped molding 1 the first leg of the U-shaped mouth 6 and is from a clamping screw 8th penetrated. By tightening the clamping screw 8th is one at the free end of the clamping screw 8th arranged clamp body 9 pressurized or applied in the assembly target position, so that in the U-shaped mouth 6 arranged metallic conductors 2 . 2a . 3 through the clamp body 9 against the second leg 11 of the U-shaped mouth 6 are held clamped or clamped.

According to the invention, the clamping body 9 partially circular and formed from a first position such as in 1 and 2 shown in which the clamp body 9 at least partially between the thighs 4 . 5 of the U-shaped molding 1 is led into another position, such as in the 3 and 4 shown in which the clamp body 9 is arranged transversely to the first position and along the base 10 of the U-shaped mouth 6 is guided, adjustable or adjusted.

This makes it possible with only one construction clamp, both parallel metallic conductors 2 . 2a . 3 to clamp together and two mutually orthogonal arranged metallic conductors 2 . 2a . 3 to clamp together, so that for the discharge of lightning currents, the clamped together metallic conductors 2 . 2a . 3 Having direct contact, so that a flow of current through the construction terminal through is avoided, since the dissipated lightning current directly into a second metallic conductor 2 . 2a . 3 which can form an end conductor flows.

In addition, with such a construction clamp in a particularly quick and easy way without the aid of special tools or expertise two round metallic conductors 2 . 2a or a round metallic ladder 2 . 2a and a flat metallic conductor 3 be clamped together. In this case, the metallic conductors 2 . 2a . 3 depending on the situation on site in a parallel position or be arranged in a mutually orthogonal position.

As can be seen from the figures, the length of the part-circular clamping body 9 larger than the width. This ensures that when adjusting the clamping screw 8th that the clamp body 9 on the clamped to each other metallic conductors 2 . 2a . 3 moved, the clamp body 9 either between the thighs 4 . 5 , such as off 1 and 2 visible, guided or in the offset by 90 ° position, for example, in the 3 and 4 is shown along the base 10 of the U-shaped mouth 6 is guided. Thus, the movable at the free end of the clamping screw 8th arranged clamp body 9 always at least partially surround the respective metallic conductor with its inner lateral surface. Due to the part-circular design of the clamp body 9 is also the Aneinanderklemmen of metallic conductors, in particular round conductors also possible with different diameters.

In this case, the adjustment of the part-circular clamping body 9 each about 90 ° within the range of a groove-like recess 12 those in the base 10 of the U-shaped mouth 6 is arranged. Depending on the desired position of the clamp body 9 this is without jamming metallic conductor by adjusting the clamping screw 8th in the region of the groove-like recess 12 adjusted to be rotated there in the offset by 90 ° each position. Subsequently, the clamping screw 8th again adjusted in the release direction and the clamp body 9 will now depending on its location along the base 10 of the U-shaped mouth 6 ( 3 and 4 ) or between the thighs 4 and 5 of the molding 1 , like from the 1 and 2 can be seen.

This is when tightening the clamping screw 8th clamped metal conductor for clamping on each other 2 and 2a or 2 and 3 the movement of the clamping body 9 reduced to a necessary minimum and as soon as the clamp body 9 the leader to be jammed 2 . 2a . 3 contacted, fixes the clamp body 9 in the desired clamping position.

Moreover, in the second thighs 11 of the U-shaped mouth 6 another groove-like recess 13 trained, in particular, like 7 can be seen, for pre-positioning a round metallic conductor 2a can serve.

The groove-like recess 12 at the base 10 of the U-shaped mouth 6 can also be used as an additional function to pre-position inserted flat metallic conductors 3 , in particular from 6 can be seen.

The invention thus provides an improved construction clamp of the type mentioned above, which makes it possible to quickly and easily, in particular to parts of the reinforcement in concrete construction, such as grid-like reinforcing mats, corresponding metallic conductors 2 . 2a . 3 to disconnect lightning currents. This is done in a particularly simple and fast manner without the aid of specialized tools. In addition, such a construction clamp is a particularly durable solution there.

The invention is not limited to the embodiment, but in the context of the disclosure often variable.

All disclosed in the description and / or drawing single and combination features are considered essential to the invention.
