DE10200713B4 - Hook for pressing parts against a building surface - Google Patents

Abstract

The invention is based on the object of proposing a hook for pressing parts against a building surface, which can be safely and stably anchored and used in the masonry in the entire area of the building surface and whose clamping jaws can be moved and locked over a large area. For this purpose, a building bore 14 is made in the masonry 13, the diameter of which is the same as or slightly larger than the diameter of the mandrel 9. The mandrel 9 is screwed or pushed into the structure bore 14. Then the mandrel sleeve 2 is pushed in the direction of the masonry until the movable pressure plate 6 on z. B. a board gauge 15 is applied. By turning the clamping screw 5, the pressure washer 6 is shifted until both the board gauge 15 and the mandrel sleeve 2 are fixed. The mandrel sleeve 2 is fixed on the mandrel 9 by a tilting movement in that the elevations, which are preferably arranged at at least one end of the mandrel bore 8, enter into a form-fitting connection with the mandrel thread 11 of the mandrel 9. After the work has been completed, the connection is released by loosening the clamping screw 5 and removing the hook from the masonry 13.

Description

The invention relates to a tool for use in the construction trade, with which the cost of pressing parts on walls or ceilings of buildings can be significantly reduced.

State of the art

In the construction industry, it is customary to simplify certain work by the use of gauges. It is known to attach so-called Bretterhren (plaster boards) as Putzbegrenzungen on the outer corners or on opening reveals to get sharp edges when processing the plaster on the masonry. These bretzhren are attached with cleaning hooks. These cleaning hooks consist of a forged mandrel, which is guided through an opening in sliding jaws. To attach the bretterhre the mandrel is driven into the masonry. Subsequently, the jaws is pushed over the aligned Bräthrenhre and moved by means of a hammer on the mandrel so far until both the oven and the jaws are fixed. After work, the connection is released by the cleaning hook is loosened in the masonry and removed.

This connection system, which has been used for many years, has some disadvantages:
If the mandrel is not driven in a sufficiently large distance to the outside corner or the opening reveal, there is a risk that parts of the masonry or - especially in the renovation of old buildings - break out of the existing plaster. This creates an additional workload due to the need to repair these damages. As a result of the distance to be maintained by the outside corner or the opening reveal the plastering gauges used are to be made correspondingly wide and thick.

Even with a sufficiently large distance from the outer corner or the opening reveal not every attempt. Often the driving of the Borns must be repeated several times until it has a tight fit to fasten the plaster can. The jaws of the cleaning hook can only be moved and locked over a limited area. The further the jaw is moved outward, the greater the risk that the mandrel inadvertently loosens when fixing the element to be fastened. Therefore, the thickness of the elements to be fastened is limited.

In the DE 297 05 331 U1 is a tensioning device ( 11 to 14 ) similar to the known tension clamp described its force rail 11 by means of clamping screw 21 and holding body 20 to attach to a chopping block is. Task here is the longer-term attachment of a clamping device to a wooden body. That's why a standard wood screw 21 (here with gag 22 ) can be used, which is easily screwed into the wood body and has a firm hold in the wood. This wood screw 21 is also loaded perpendicular to the screw axis, whereby the clamping forces of the ferrule are safely absorbed. This construction is only suitable for wooden carrier bodies.

In the BE 1010202 A3 and FR 2 615 888 A1 hooks are disclosed, which are known to be secured by wrapping in the masonry. The disadvantages of these solutions have already been described above. In addition, these have at the end of the movable jaw a threaded receptacle for a threaded spindle. With the spindle with handwheel, the clamping of parts can obviously be better dosed than with hammer blows. Except for one embodiment, the threaded spindle is arranged perpendicular to the mandrel axis. The clamping force thus acts laterally on the mandrel, so that it can not be easily pulled out of the masonry. In the 3 of the BE 1010202 A3 The axes run parallel. Here there is a risk that when pulling the mandrel tip is pulled out of the masonry.

According to the EP 325 128 A2 is a screw 42 in a hole 41 placed in a masonry. The screw 42 Shall move the frame here 16 prevent it is guided by this. It is a solution for a permanent fixation and a load on train is not available. The bracket supports the frame with the threaded spindle and serves for local fixation. The screw 42 is attached after fixation and remains in the frame / masonry. This training is thus used only for a few applications for fastening.

Object of the invention

The invention has for its object to provide a hook for pressing parts of a building surface, which is anchored and usable in the entire area of the building surface safe and stable in the masonry and the jaws are displaced over a large area and locked.

This problem is solved by a hook according to claim 1.

• a) Der Dorn 9 kann mit geringem Abstand zur Außenecke oder zur Öffnungslaibung befestigt werden, ohne daß die Gefahr besteht, daß Teile des Mauerwerkes 13 oder – insbesondere bei der Altbausanierung – des vorhandenen Putzes ausbrechen.
• b) infolge des geringen Abstandes von der Außenecke oder der Öffnungslaibung können die verwendeten Putzlehren entsprechend schmal und/oder dünn gehalten werden.
• c) Es gelingt praktisch jeder Versuch, den Dorn 9 im Mauerwerk zu befestigen.
• d) Die Dornhülse 2 des Hakens ist praktisch über den gesamten freien Bereich des Dorns 9 verschieb- und arretierbar. Auch bei maximaler Verschiebung der Dornhülse 2 besteht nicht die Gefahr, daß sich der Dorn 9 aus dem Mauerwerk löst. Die Dicke der zu befestigenden Elemente ist daher nur durch die Verschiebbarkeit der Dornhülse 2 begrenzt.
• e) Stahleckzargen sowie Stahlumfassungszargen, die sehr dünn und biegsam sind, können leicht wandseitig ausgerichtet uns anschließend arretiert werden. Gerade bei den dünnen und sehr flachen Stahlzargen, bei denen die Bekleidung sehr schmal ist, ist es vorteilhaft, daß der Dorn 9 sehr dicht an der Laibung verankert werden kann.

Compared with the conventional hooks, the following advantages are associated with the use of the hook according to the invention:

• a) The thorn 9 Can be fixed with a small distance to the outside corner or the opening reveal, without the risk that parts of the masonry 13 or - especially in the Altbausanierung - erupt the existing plaster.
• b) due to the small distance from the outer corner or the opening reveal the used cleaning gauges can be kept correspondingly narrow and / or thin.
• c) Virtually every attempt succeeds, the thorn 9 to be fixed in the masonry.
• d) The mandrel sleeve 2 The hook is practically over the entire free area of the spine 9 movable and lockable. Even with maximum displacement of the mandrel sleeve 2 there is no danger that the thorn 9 released from the masonry. The thickness of the elements to be fastened is therefore only by the displaceability of the mandrel sleeve 2 limited.
• e) Steel corner frames and steel surround frames, which are very thin and flexible, can easily be aligned on the wall and then locked. Especially with the thin and very flat steel frames, where the clothing is very narrow, it is advantageous that the thorn 9 can be anchored very close to the soffit.

Further expedient embodiments are specified in the three subclaims.

Examples

Hereinafter, the invention will be explained with reference to Ausführunsbeispielen.

1 shows a hook according to the invention in side view.

2 shows detail A in section.

3 shows a further variant of the detail a in section.

4 shows the hook during use.

5 shows another variant of the use of the hook.

The in 1 illustrated hook according to the invention consists of the clamping screw sleeve 1 and mandrel sleeve 2 , which by means of a connecting element 3 connected to each other. The clamping screw sleeve 1 has a threaded hole inside 4 in which a clamping screw 5 is guided. The clamping screw 5 has at its lower end a movable pressure plate 6 and at its upper end a Spannschraubenheft 7 ,

The mandrel sleeve 2 has a spike hole inside 8th ( 2 and 3 ), in which a thorn 9 is guided. The diameter of the mandrel bore 8th is greater than the diameter of the mandrel 9 (Clearance), so that the thorn 9 in the spine hole 8th can be moved easily. The upper end of the spine 9 stuck in a thorn book 10 , Over the entire free length is the thorn 9 with a thorn thread 11 Mistake. The thorn thread 11 is preferably designed as a self-tapping thread. In the spine hole 8th the mandrel sleeve 2 Elevations are arranged, which are designed so that they with the threads of the mandrel thread 11 can make a positive connection. It has proven to be advantageous, these elevations as internal thread ( 2 and 3 ). The spine sleeve thread 12 can over the entire length of the mandrel bore 8th walk ( 2 ) or at least at one end of the mandrel bore 8th to be appropriate ( 3 ).

4 shows the application of the hook according to the invention:
This is done by means of an existing on each construction site drill in the masonry 13 a building bore 14 introduced, whose diameter is equal to or slightly larger than the diameter of the mandrel 9 is. Into the building bore 14 becomes the thorn 9 screwed in or inserted. Subsequently, the mandrel sleeve 2 in the direction of masonry pushed so far until the movable pressure plate 6 at the aligned oven 15 is applied. By turning the clamping screw 5 becomes the pressure plate 6 until postponed until both the bretzhrehre 15 as well as the mandrel sleeve 2 are fixed. The mandrel sleeve 2 is caused by a tilting movement on the mandrel 9 fixed by the preferably at least one end of the mandrel bore 8th arranged elevations with the mandrel thread 11 of the thorn 9 make a positive connection. After work, the connection is released by the clamping screw 5 loosened and the hook from the masonry 13 is taken out.

The use of the hook according to the invention is not limited to the use in plaster work. The hook can be used anywhere where an element can be temporarily fixed to a structure into which a hole can be inserted.

The hook according to the invention can also be used in the assembly of fixtures, which must be aligned and fixed before final assembly. Door frames or steel corner frames as well as steel frame frames can be easily aligned and fixed with the aid of the hook. 5 shows how a steel frame 16 fixed after aligning with filler or construction foam 17 to be backfilled.

Even with the overhead mounting of the hook according to the invention can be used. The substructure for ceiling panels can be easily aligned and fixed.
