Description

Plate for driving into masonry

The invention relates to a plate for driving into masonry, comprising a substantially plate-shaped base body, and a system for driving a plate into masonry.

The invention further relates to a method for driving a plate into masonry.

From the prior art, for example from the documents HU 185162B, DE 29723068 U1 and AT 401248B, panels of the type mentioned at the beginning are known, which are used for drying walls. Here, a plate is driven essentially horizontally into a bearing joint in a masonry, for example made of bricks, and then serves as a barrier layer between an upper part and a lower part of the masonry, so that rising moisture can no longer reach the lower part into the upper part of the masonry can.

Usually, several plates made of corrugated material, for example steel, which are rectangular in plan view, are arranged next to each other in a horizontal joint in order to form a continuous barrier layer. The panels are usually driven into the joint using driving machines.

However, the disadvantage of the known plates is that high forces are required when driving the plate into the joint, which on the one hand requires appropriate driving devices and on the other hand leads to a lot of noise and dust. Furthermore, the panels are only connected to the masonry in a force-fitting manner, with the upper part of the wall pressing on the panel and holding it in the desired position. In addition, it has been shown that when a slab is driven into masonry, damage is often caused to the masonry.

It is therefore an object of the invention to provide a plate of the type mentioned at the outset, which allows easier driving into masonry, in particular a joint in masonry. Furthermore, a better connection of the driven slab with the masonry should be made possible. According to the invention, in a plate of the type mentioned at the outset, at least two projections are arranged on at least a first side of the base body, which extend essentially in the same plane as the base body. The projections are not directly connected to one another, but are each connected to the base body.

The base body forms a plate plane and has a small strength or thickness compared to the extent in the plate plane, i.e. in the width and length directions. The projections are arranged on a side wall defining the thickness of the base body and also extend essentially in the plane of the plate, the thickness of the projections being small compared to the extent in the width and length directions. The projections and the base body preferably have essentially the same thickness. The base body is preferably essentially rectangular in plan view, but can also have a different shape if it is necessary or useful for the application.

The base body can be flat. This is the usual application for inserting the plate into a wall with dividing planes, which are formed, for example, by upper edges of bricks and layers of mortar arranged on them.

However, it can also be advantageous to design the base body in such a way that it extends in several levels, whereby the individual levels can be connected by jumps. The jumps can be normal to the planes, so that a corresponding base body can be formed, for example, by a correspondingly bent sheet metal. Such a plate can also be referred to as a stepped plate.

It is preferably provided that the projections have a tip on the side facing away from the base body, the side edges of which enclose, for example, an acute angle or an angle of 90° to 150°. This tip makes it easier to drive the panels into the joints in the masonry. The projections can also have leg-like boundaries, in particular trapezoidal or teardrop-shaped projections, in order to enable particularly easy driving, in particular due to a wedge effect. Furthermore, during use, the tips can be inserted into engagement openings, in particular holes, arranged in the masonry before the remaining plate, in particular the rest of the projections and the base body, are driven into the masonry. In addition, the projections can be used as a grid for marking the access openings in the masonry. Through such intervention openings or holes, undesirable damage to the wall can also be easily avoided. The inventor recognized that without appropriate openings, a so-called congestion effect can occur, which causes the masonry to be displaced in the direction in which the plate is driven in, so that the wall would then have a curvature. This is avoided by using appropriate engagement openings, since debris can then escape into these engagement openings.

Particularly preferably, it is provided that the projections are each designed in plan view with tapering side edges or legs, in particular trapezoidal, oval or essentially triangular, with one side of the triangle being arranged on the base body. This creates a crown shape in which, for example, the tips of the triangles are arranged on the side facing away from the base body. Due to the tapered side edges, a wedge effect is achieved, which enables the plate to be driven in easily.

Alternatively, the projections can also be trapezoidal or teardrop-shaped, for example.

Furthermore, it is preferably provided that at least two further projections are arranged on a second side of the base body, the second side preferably being opposite the first side. The first and second sides are particularly preferably essentially parallel to one another. This arrangement increases the flexibility of the use of the plate, and in particular when the plate is driven into the masonry, the projections on the first and second sides can be bent relative to the base body in order to achieve a better connection of the plate to the masonry and thus a more stable arrangement create.

A particularly simple form of production is possible if the first side and the second side have an identical contour, for example points or serrations. The base body can then be manufactured particularly easily, for example Cutting or punching, whereby several base bodies can be produced from a sheet of corresponding width without any waste. A cut with which a contour of a second side of a first base body is produced simultaneously forms a contour of a first side of a subsequent second base body, so that the contour of the second side is, so to speak, complementary to the contour of the first side.

It is therefore preferably provided that the projections on the second side are complementary to the projections on the first side.

Preferably, at least three, preferably at least four, particularly preferably at least five projections are provided on the first side and/or the second side.

In order to enable a better connection of several plates to one another, it is preferably provided that the base body has a tab along a third side. The tab is preferably formed by a doubly curved end region of the base body, with a first curved section directly adjoining the base body in cross section, and a second second section adjoining the first section and bent in the other direction. The first section and the second section preferably each have an angle of 30°-60°, preferably 40°-50°, particularly preferably approximately 45° relative to the base body. Furthermore, the first section and the second section preferably enclose an angle of 70° to 110°, preferably approximately 90°. Preferably, the tab extends substantially along the entire length of the third side.

In order to enable a plate to be connected on both sides, it is preferably provided that the base body has a tab along a fourth side. The third side and the fourth side are preferably essentially parallel to one another. The tab on the fourth side is preferably designed essentially the same as the tab on the third side. Particularly preferably, the tab on the third side and the tab on the fourth side are arranged essentially in opposite directions, with the first section of the tab arranged on the third side extending in a first direction and the first section on the fourth side in a second direction, and the second section has a substantially equal angle to the base body. This enables a The second sections of two panels lie on top of each other, creating a good and tight connection between two panels arranged next to each other in the masonry.

In order to further improve the connection of the plate to the masonry, it is preferably provided that at least one of the projections has a connecting means, for example a connecting opening. All projections on a plate preferably have a corresponding connecting means. A connection opening can, for example, be designed as a hole and be used to firmly connect the projection (and thus the plate) to the masonry using screws or nails.

Furthermore, it is preferably provided that a material weakening, in particular a material taper such as a groove or a perforation, is provided in the area between the base body and at least one projection. This material taper enables or facilitates the bending of the projection relative to the base body. The material taper can be designed on one or both sides. Furthermore, the material taper can be continuous or change longitudinally, for example in the form of a perforation. It is particularly preferred that the material taper is designed to form a stop between the projection and the base body. This makes it possible to bend the projection up to a predefined angle, for example approximately 90°, relative to the base body.

The base body and the projections are preferably formed in one piece. Furthermore, the base body and the projections preferably consist of the same material, for example stainless steel. The thickness of the plate is preferably essentially the same in all areas. The width of the plate can be, for example, 100 mm to 1100 mm, the length, for example, 50 mm to 800 mm and the thickness, for example, 0.2 mm to 15 mm, in particular 1 mm to 10 mm.

According to the invention, a system for driving a plate into masonry is further provided, comprising a plate according to the invention and at least one guide element for guiding the plate. The guide element serves to make it easier to drive the plate into masonry in the desired position and at the desired angle. The guide element preferably comprises one or two rails into which the Side areas of the plate engage and are guided in this way. The rail or rails preferably comprise a groove in which a side region of the plate can be arranged in order to effectively prevent undesirable deflection of the plate. Two rails are preferably provided, which are connected to one another via a web, preferably rigidly. The plate can be guided stably on both sides. In order to be able to accommodate any tab that may be present, a cavity is preferably formed on the side of the groove facing away from the plate, which has a larger cross section than the groove and is suitable for receiving the tab.

In order to make it easier to drive the plate into the masonry, it is preferably provided that a drive element is provided for moving the plate relative to the guide element. The drive element can be, for example, a drill, which acts on the plate via a corresponding gear in order to drive it translationally into the masonry. Furthermore, the drive element can be, for example, a hammer drill or a hammer drill, which provide a translational movement. In order to transmit the translational movement of the drive element to the plate, an adapter is preferably provided which provides a connection between the drive element and the plate. This adapter can, for example, be a receptacle with a stop into which a movable element of the drive element can be inserted. The adapter holds the drive element in the desired position relative to the plate, so that optimal force transmission from the drive element to the plate is achieved. In order to hold the plate on the other side, the gear or the adapter preferably has a groove into which the plate can be partially inserted and held in the groove. This prevents the plate from buckling or buckling during the driving process. The provision of a gear or an adapter makes it possible, in particular, to first drill engagement openings in the masonry using a drive element and then to use this drive element to drive the plate into the masonry.

Alternatively, the plate can also be driven into the masonry manually, for example with a hammer or other aid.

Furthermore, according to the invention there is a method for driving in an inventive

Plate provided in a masonry, with engagement openings in a first step the masonry is incorporated, the distance between two adjacent engagement openings essentially corresponding to the distance between two adjacent projections of the plate, in a second step the projections of the plate are each at least partially inserted into an engagement opening and in a third step the plate is driven into the masonry. The first step takes place first, then the second step and finally the third step. The distance between two projections of the plate arranged next to one another is understood to mean the distance between the frontmost areas, i.e. those furthest away from the base body, of two projections arranged next to one another. In particular, this distance corresponds to the distance between the tips of two projections arranged next to one another.

In addition, one or more further engagement openings can be provided between the engagement openings into which the tips can engage.

These engagement openings arranged between the tips can be used in particular to accommodate waste in order to make it easier to drive in the plate.

For example, a further engagement opening or a bore for receiving waste can always be arranged centrally between two engagement openings corresponding to tips. A distance between the holes then corresponds to half of a distance between the tips.

The access openings are arranged in the masonry, preferably in a joint in the masonry. To mark the engagement openings, the plate can preferably be brought to the desired location and easily driven into the masonry, for example a few millimeters, so that the position of the engagement openings is marked. The engagement openings can then be made, for example using a drill. It is preferably provided that overburden openings are provided between the engagement openings. The overburden openings are, for example, designed like the engagement openings and serve to provide a space for receiving the masonry material displaced by the projections, in particular the joint. When the plate is driven into a joint, the material breaks out due to the wedge effect of the projections between the engagement openings and is distributed evenly in the joint due to the overburden openings. In the third step, the plate is essentially driven into the masonry in a translational manner, for example using a drive element, until the plate is in the desired position. The plate is preferably driven into the masonry until the base body is essentially completely covered by the masonry in plan view and only the projections protrude at least partially from the masonry.

In order to improve the connection between the plate and the masonry, it is preferably provided that in a fourth step at least one projection is bent relative to the base body. The fourth step occurs after the third step, when the plate is already placed in the desired location in the masonry. It is preferably provided that one projection in each case is bent in one direction, for example upwards, and the adjacent projection(s) is bent downwards, so that a particularly good connection with the masonry is achieved. After the fourth step, the bent projections preferably have an angle of approximately 90° to the base body or to the plate plane.

Furthermore, it is preferably provided that in a fifth step the projection(s) are connected to the masonry using connecting means, for example connection openings, and fixing means, for example screws.

The invention is explained in more detail below using an exemplary embodiment shown schematically in the drawing. 1 shows a schematic representation of a plate according to the invention before being driven into masonry, Fig. 2 shows a schematic representation of two plates according to the invention before being driven into masonry, Fig. 3 shows a detailed view of a tab of a plate according to the invention, Fig. 4 a view of a plate according to the invention together with guide means before driving into masonry, Fig. 5 a detailed view of the connection of a plate according to the invention with a drive element and Fig. 6 another plate.

1 shows a plate 1 which has a base body 2 which is essentially rectangular in plan view and a plurality of projections 3 arranged on a first side of the plate 1. The projections 3 are each essentially triangular and lie essentially in the same plane as the base body 2 and have tips that form an acute angle. The tips of the projections 3 are arranged in the direction of a joint 4 of a masonry 5, with each projection 3 being assigned an engagement opening 6 arranged in the joint 4. Overburden openings 7 are arranged between the engagement openings 6. The engagement openings 6 and the waste openings 7 are each the same and designed as bores. The base body 2 of the plate 1 further has further projections 3 on a second side essentially opposite the first side (FIG. 2). Furthermore, a tab 8 is arranged in the area of a third and a fourth side of the base body 2.

In Fig. 2 two plates 1 are shown, which are essentially the same and are to be arranged next to each other in the joint 4 of the masonry 5. In order to create a good connection between the two plates 1, the tabs 8 of the two plates 1 are connected to one another. This makes it easier to drive in the plates 1 and enables a tight connection between the two plates 1 in the masonry 4. Furthermore, the projections 3 are shown on the second side, which essentially correspond to the projections arranged on the first side of the plates 1 facing the masonry 5 3 are arranged opposite each other.

3 shows a detailed view of a connection between two tabs 8 in cross section. The tabs 8 each have a first section 9 and a second section 10, the first section 9 being bent in one direction relative to the base body 2. The second section 10 adjoins the first section 9 and is bent in the other direction. The angle of the first section 9 and the second section 10 to the base body 2 is approximately 45° in each case. The angle included by the first section 9 and the second section 10 is approximately 90°. Since the two tabs 8 are designed to be opposite to each other, the connection shown is made possible, in which the second sections 10 lie on top of each other.

4 shows a system comprising a plate 1 according to the invention and a guide element 11. The guide element 11 comprises two rails 12, each of which has a groove 13 for receiving the plate 1. The two rails 12 are connected to one another via a web 14. In this view, plate 1 is in Guide element 11 arranged, the plate 1 being guided in the grooves 13. In order not to damage the tabs 8, the grooves 13 on the side facing away from the plate 1 open into a cavity 15, in which the tabs 8 are arranged during guidance by the guide element 11. In order to drive the plate 1 in the direction of the arrow 16 towards the masonry 5, a drive element 17 designed as an impact drill is provided, which acts on the plate 1 via a corresponding adapter 18. The adapter 18 has a receptacle 19 into which the drive element 17 is partially inserted and held. In order to ensure the transmission of the movement of the drive element 17 to the plate 1, the plate 1, in particular the projections 3 arranged on the second side of the base body 2, is partially arranged in a groove 20 of the adapter 17. By partially arranging the plate 1 in the groove 20, the plate 1 is prevented from buckling or buckling during the driving process.

In Fig. 5, the connection between the plate 1 and the adapter 17, in particular the groove 20, is shown in an enlarged view.

Fig. 6 shows a plate 1 designed as a step plate for driving into masonry 5, which, in contrast to the plates 1 shown in FIGS. 1 to 5, extends in several levels. The individual planes of the plate 1, which are horizontal when used as intended, are coupled by a vertical jump or a vertical connecting element in the plate 1, so that this plate 1 can be formed simply, for example, by bending. This plate 1 can also be used to dry-wall a wall that does not have a continuous horizontal dividing plane or continuous horizontal layers of mortar, but instead has vertical joints in the masonry 5. A basic application of this plate 1 naturally corresponds to the use of the plates 1 shown in FIGS. 1 to 5.
