Description

"Device for fixing a drill stand

for a drill "

The present invention relates to a device for fastening a Bohrstän- for a drilling machine on a building or component with a clamping device and a support member, wherein the clamping device engages the building or component in the operating state, the support member in the operating state on the one hand contacted the building or component and on the other hand serves for fastening of the drill stand and wherein the clamping device and the support member are connected together in the operating state.

In the construction industry it often happens that a railing has to be installed on a balcony railing, that a fence including posts has to be erected on a wall base or also banisters, room dividers, cantilevers, casters and the like more on a building or on a building Component are to be attached. In such cases, drills are used, which can initiate a very high force in the building and larger holes from 6 mm up to 100 mm or more, especially for rebar connections can realize. Such drills, especially diamond dowel drills or diamond core drills, also pierce reinforcements within concrete and have high torque.

It will be understood that a single person is incapable of keeping such a powerful drill in an accurate position. Therefore, there are drill stands that hold the drill. A drill stand is usually dowelled by means of a stand on the building / component. That is, first holes must be drilled in the structure or the component, dowels are set so that the base is securely connected to the building / component and finally the drill stand has a secure footing and can support the drill.

If the actual hole drilled for the fence post or the like, of course, the base is removed and of course the other holes must be closed, in particular plastered. The building / component takes damage and loses optically in quality. In addition,

CONFIRMATION COPY It can also lead to building material corrosion, especially if cracks occur between the plaster or filler and the existing material.

The above problem does not occur when using a stand that does not require fixed dowelling. From the Internet presence of the company Cardi under "www.cardi.biz" concerning the leaflet there for the series "Three phase core drills -" Freccia rossa series "» is known a wall clamping device comprising a narrow support strip and a screw clamp. The support bar and the traverse of the screw form a T-shape and are firmly and permanently connected to each other. At the free end of the support bar a pressure clamp is provided, which should establish the strength at the opposite end of the screw. From the receiving bar protrudes a fastener for the drill stand.

Although the dowel problem does not occur, the known wall clamp does not have sufficient stability. The pressure exerted on the free end of the support bar is not secured. The moment the drilling starts, the support bar lifts up from the wall, interfering with the stability of the drill stand, and the well can no longer be accurately positioned. Another stability-reducing factor is the strip-like, narrow shape of the support bar. The drill stand is usually only partially resting on the support bar. Although it is fixed, but it can lead to an unbalanced attachment and thus to a tilt of the drill stand and finally the drill.

Based on the from the Internet presence of the company Cardi under "www.cardi.biz" concerning the leaflet there for the series "Three phase core drills -" Freccia rossa series "known wall clamp device the invention is based on the object, a device of to specify the type in question with improved stability.

The above object is solved by the features of claim 1. Thereafter, a device of the type in question is further developed in such a way that the support part consists of a frame construction and a receiving plate. is that a further clamping device is provided and that both clamping devices are connected in the operating state with the frame construction. Based on the from the Internet presence of the company Cardi under "www.cardi.biz" concerning the leaflet there for the series "Three phase core drills -" Freccia rossa series "known Mauerklemmeinrichtung has been recognized that these in terms of on the low stability at the opposite end of the screw terminal free end of the support member endangers the stability of the drill stand. In addition, it has been recognized that the narrow, strip-like shape of the support member additionally endangers the stability of the drill stand. Further, it has been recognized that it would be desirable if the device would provide high stability. According to the invention it has been recognized that the stability of the device can be improved if instead of a narrow, strip-shaped support member, a receiving plate is provided, which is not itself attached to the building, component, but is disposed within a frame, the two screw terminals on the building , Component is attached. In this way, the attachment to opposite ends of the frame construction is possible and the plate-like design of the support member ensures optimum attachment of the drill stand. Just the possibility of opposite attachment gives the entire device according to the invention strength and stability. According to a preferred embodiment, the frame construction of the device could comprise two opposite transverse parts and two opposite longitudinal parts. In general, the longitudinal parts will be longer than the cross members, since in this way the clamping devices move from the center of the action and form no obstacles. The frame construction could also be square. In practice, often come structures, components with rectangular surfaces, so that the longitudinal and transverse parts of the frame structure are arranged at right angles to each other. In each case, the longitudinal parts and the cross members are arranged parallel to each other. With regard to a simplified handling, the frame construction and the two clamping devices could be detachably connectable. Alternatively, of course, a welded joint could be realized. For the preferred releasable connection with the frame construction, each clamping device could comprise at least one fastening means.

According to a proven and functional embodiment of the invention, the clamping devices could be in the form of screw terminals. These have proven their worth especially with the use of diamond drills, as there are few vibrations due to cutting machining. As an alternative to screw terminals, lever handles or screws are possible.

The screw could now - as known from practice - include a traverse with two movably arranged carriers for jaws. In view of the fact that a building or component is to be overlapped and clamped between the clamping jaws, two clamping jaws spaced apart from each other and facing one another, are provided per clamping device. As a building, for example, the top surface of a wall or balcony balustrade come into consideration. But also components, such as trusses of a barn, cantilevers on buildings can be equipped with the device according to the invention.

The use of the known screw is also so advantageous because the traverse can have different dimensions and thus the attachment to wider dimensioned structures / components is possible. The fastening means are always to be arranged so that the connection to the frame component - over transverse and / or longitudinal part - can be produced. From the traverse, the fastener could protrude for releasable connection with the frame construction. This fastener could be connected in the operating state at least with the longitudinal part of the frame structure. Preferably, two fastening means are provided per screw clamp, which engage on both longitudinal parts of the frame construction. During the operating state, the respective traverse of the respective screw clamp could extend parallel to the transverse part of the frame construction and both perpendicular to the traverse and perpendicular to the jaw carrier.

In order to realize a high strength of the connection between the frame component and screw terminals, the fastening means could overlap wide areas of the longitudinal parts of the frame component and be fixed at at least two points. For example. could protrude threaded pins on the frame construction, pass through the through-holes on the fastening means of the screw terminal, and fixing the screw clamp and the frame construction by means of thumbscrews. Specifically, each screw could be assigned two fasteners, each with two holes. Likewise, four setscrews per fastening means could be provided on the screw terminal of the frame construction, which extend primarily to the longitudinal members or in the corner region of the frame construction.

As with the known device of the type in question could also protrude from the support part a threaded pin for fixing the drill stand.

According to a particularly preferred embodiment of the invention, the device could comprise an additional angle plate, which serves to attach the drill stand angled to the receiving plate. Such applications are required if, for example, handrails should not be fastened on the top surface of the parapet, but on the side surface of the parapet or a wall base or other structure / component. Also, the variation side surface, front surface - bottom is possible, which is the case, for example, in roof structures.

The angle plate could have a section with a recess for the threaded pin of the receiving plate and a section with its own connecting mandrel. The angle between the two sections of the angle plate could be approximately 90 ° in view of the structures / components usually rectangular shapes. In order for the angle plate to be stable enough for the drill stand and the drill, bores could be provided on the first section of the angle plate. be seen, which are tangible by grub screws of the receiving plate and can be locked with wing nuts. This would be an attachment over the top surface of the building / component realized, which is basically sufficient. In order to make a backup on the side surface of the building / component for additional support, could be provided on the second portion of the angle plate clamping members. These could either exert direct pressure on the side surface or else a board or another intermediate component could be arranged between the side surface and clamping components, so that the clamping effect is exerted indirectly, sparing the building / component.

Of particular advantage and essential to the invention is when the screw, the frame construction with the receiving plate and the optional angle plate are separate components of a kit.

It should be noted that the device can be used particularly advantageously in diamond drilling machines. The device according to the invention gives construction companies the opportunity to offer the diamond drilling services themselves, as they - as before - to deliver to specially specialized diamond drilling service.

The handling of the device according to the invention comprises the following steps:

First, the support part is connected to the clamping devices. This can be done while the support part is placed on the building / component or separately. At the latest in the assembled state, the device is positioned so that the clamping devices engage over the building / component. Then, the determination of the device via the clamping device on the building / component. Finally, the drill stand is attached to the support part. Now the drill can be inserted into the drill stand and fixed. In the event that the drilling angled to the top surface of the building / component is to be performed, after mounting the frame member with the receiving plate by means of the two clamping devices still mounted an angle plate to which then the drill stand is attached. The drill stand could then be optionally attached. There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the claims subordinate to claim 1, on the other hand to refer to the following explanation of an embodiment of the invention with reference to the drawing.
