Independent claims are also included for (a) a support foot containing two or more of these fittings, and (b) constructions, especially halls with beams resting on supports on foundations, these optionally pre-fabricated concrete parts being joined together using the connection fitting or support foot.

Description

The invention relates to a device for connecting two components, for example a post on a foundation, wherein the device has a base with bore, in which a holding means engages and transmits forces and attack one or more load-bearing rods on the device or the base.

Such a device is known in the art:

The European patent application 952 265 and the priority of this application German patent application 198 17 832 describe a column shoe for fixing a concrete pile on a base. Again, here is a bottom plate provided with a bolt hole. Furthermore, a housing is provided which receives a plurality of reinforcing bars. The housing divides the bottom plate into several sections. The housing has a housing bottom on which front reinforcing rods (here called anchoring members) are attached. Furthermore, rear reinforcing bars are provided, which are arranged in the at least two sections formed by the housing.

From the publication WO 98/02625 Improvements of fasteners of concrete structures are known. In this document also concrete columns are described which have a base plate on one of the concrete parts to be joined, which has a centering pin. This centering pin is inserted into a correspondingly formed mounting plate of another concrete element such that a centering of the concrete part takes place through the pin.

From the publication EP 0 952 265 A2 is a column shoe for fixing a concrete pile on a substrate known. In the publication, a base for the column shoe is proposed, to which three-angularly arranged housing legs constructed at right angles to the base, carrying in particular at their end load bearing rods. Here, the housing leg surmounted the base.

The German patent application 195 14 685 describes a pile shoe for securing a concrete pile to a substrate, the pile shoe having a bottom plate with a bolt hole and reinforcing bars projecting vertically upwards on the bottom plate. A rigid angle steel construction is attached to the floor panel with the side planes of the angle steel construction being substantially perpendicular to the plane of the floor panel. The angle steel construction is intended to absorb compensating forces that are transverse to those of a force acting in the bolt hole bolts and the reinforcing bars absorbed forces act so that the balancing forces do not increase the required rated load capacity of the reinforcing bars used.

To capture this, the concrete pile under certain circumstances tearing transverse forces complex anchoring pieces are necessary.

It should be noted that when fixing a pile to a foundation at the pile corners, one pile shoe each, as described, is to be used. Typically, for example, four pile shoes are used here. Since the dimension of the pile shoe is variable, the introduction of the anchoring piece, which for example gives a cross connection between the individual pile shoes, only in the production of the pile shoe possible and it is of course risked that the installation of the anchoring piece is omitted. At the same time, the prior art proposal does not allow easy adaptation of the entire pile shoe to various different loads transmitted to the retaining means by the reinforcing bars or load receiving bars.

The present invention has set itself the task of improving a device, as described above, to the effect that the device is as simple as possible and in use does not tend to tear out of the finished concrete part or the precast concrete part, due to transverse forces occurring.

The object of the invention is achieved by a device for connecting two components, for example a post on a foundation, wherein the device has a base with bore, in which a holding means can be inserted and attack on the base a plurality of load-bearing rods, the It is characterized in that the base is divided into two areas, the connection area with the bore and the rigidly connected terminal area, the load receiving rods are fastened next to the connection area between connection area and connection area at the protruding end of the base and at least one further load-bearing rod in the connection area is provided, wherein the load-bearing rods are designed as reinforcing bars and are attached directly to the base. Such an embodiment is easily realizable in the production of precast concrete parts. The above-described device is installed, for example, as a mounting foot in precast concrete parts, wherein the provided on the device or the mounting foot base comes into contact with the precast concrete part. Thus, it is possible to effect the load dissipation in the component not only on the load receiving rods, but to use the component itself, in the same way, with the material or deposits, such as reinforcing bars and the like of the component in the same way on the device or supported on the base. The dimensioning is done here in a conventional manner, such that no resulting turning or tilting moments remain, whereby tilting of the base is excluded under load. In general, it should be noted that the load-bearing rod, designed for example as a reinforcing bar, not only on pressure, but also on train loadable, which is not possible with a normal precast concrete or a concrete component.

In one embodiment of the invention, a device is proposed in which the load-receiving rod is connected to the device by a screw connection. When planning a building in which the device described above is used for connecting two components, the load profile can be varied with appropriate planning become. The differing forces lead to different diameters for the reinforcing bars. Now, if the device allows quick replacement of the various load bearing rods on the device, it is possible to construct the device with a small set of components in a modular manner for a variety of different needs. It is also possible that load bearing rods are charged on a train and on the other to pressure. By appropriate planning, it is possible to take the forces to be picked up on the device so that there are no resulting tilting moments on the device. The load bearing rods are also used adjacent to different directions of force. The load bearing not only describes a unidirectional force absorption, but optionally also one in both directions. This variant therefore also achieves the object according to the invention.

Of course, it is also possible to provide in a variant according to the invention that, even with the use of a screw connection for the connection of the load-receiving rod to the device or to the base, there is a support of the component on the device or base.

Again, it should be noted that under the support of the component on the device or base, both a force acting from the device against the component, as well as the other way round, to understand.

Below is spoken by the device according to the invention often as a mounting foot, without limiting the invention to the application of a foot so in the lower part of a component to be connected.

The mounting foot is incorporated or embedded in the production of the first element, for example the support in this. Conveniently, the mounting foot has a base with a bore through which a retaining means, in particular a screw or a bolt, can be guided in order to connect the fastening foot with the second component, for example the foundation foot. The mounting foot acts together with corresponding threaded sleeves and the like, which are provided in the second element.

It should be noted that the mounting foot or the device is designed as an easily manufacturable component and at the same time is suitable to safely transfer the holding forces that are impressed on the mounting screw or mounting bolts on the base, in the element. It should also be noted that the mounting foot not only easy to manufacture, but also in a simple manner to the usually designed as precast concrete element fastened or installable. This is achieved in particular by the design of the base as a bending-resistant element, which is adapted to absorb the holding forces.

Conveniently, the end of the device designed as a reinforcing bars load bearing rods, which are embedded in the first component. It is provided that possibly only but also several reinforcing bars are connected to the mounting foot. The reinforcing bars are embedded in the prefabricated concrete element and transmit the tensile forces in the element. Since the retaining forces are transferred to another element via the mounting foot, it is advantageous to have the reinforcing bar connected to the mounting foot to conveniently direct the forces as directly as possible from the reinforcing bar of the first component, for example, in the armor or in the transport armature of the second component , The arrangement is made as possible, that as possible no offset forces arise at right angles to the alignment of the reinforcing bars, which would, for example, try to rotate or tilt the mounting foot relative to the element.

It is envisaged that the reinforcing bars are welded to the mounting foot or fastened screwed in a screw. At the mounting foot, for example at its base, for example, a screw sleeve is provided, which cooperates with the reinforcing rod. The screw is welded, for example, on the device or the base. The end of the reinforcing bar in this case has an external thread corresponding to the internal thread of the screwed sleeve and thus allows a very simple mounting of the fastening foot. It is possible to construct the mounting foot modular in principle by such an embodiment. According to the desired length of the load-bearing rods different lengths reinforcing rods are screwed into the sleeves. This assembly can be used when creating the precast concrete part. Depending on the required reinforcement, it is possible to screw one or more reinforcing bars in the screw holes provided in each case. By such an embodiment, the device is optimally adapted to the respective needs.

Alternatively, it is provided that the reinforcing bar on the mounting foot is welded. For the execution of the weld several variants are possible. On the one hand, for example, it is provided that the device has a housing consisting of one or more side surfaces. The load-bearing bar / reinforcing bar is connected, for example, by a fillet weld in a mechanically loadable manner with this side surface. Alternatively, it is possible to provide a bore for receiving the load-bearing rod in the base area and to weld the load-receiving rod to the back end with the end terminating the base area. However, such a concealed weld is difficult to control.

In a preferred embodiment of the mounting foot according to the invention it is provided that the mounting foot carries a housing formed from one or more side surfaces and the side surface is substantially perpendicular to the base and the housing divides the base into a connection area with the bore and a connection area. The now proposed housing optionally assumes several functions at the same time. On the one hand, it is provided that the housing is relatively thin-walled. As a rule, the fixing foot is embedded in concrete in a first precast concrete part. The housing acts in this case as a lost formwork element and leaves afterwards the bore through which the retaining bolt or the retaining screw or other retaining means is to be stuck, free of the incoming concrete. It is sufficient if the side surfaces are relatively thin-walled, as otherwise attack in this holding forces and so on.

Alternatively, it is also possible that the reinforcing rod in the connection region attached to the housing and / or the base surface is in particular welded. In the event that the reinforcing bar is attached to the housing, so the side surface, the holding forces of the reinforcing bar on the housing or the side surface on the base surface and then transferred via the retaining bolt in the other element. The side surface, ie the housing, is thereby mechanically stressed and not only forms a formwork against the penetration of concrete into the hole. In this case, it is favorable if the side surface is correspondingly mechanically more stable, if appropriate, designed as an angle-stable sheet metal or metal piece. Conveniently, the side surface or the housing is welded onto the base surface, whereby on the one hand there is a simple production and on the other hand also a mechanically good loadable connection.

The arrangement of the housing on the base is chosen so that, where appropriate, the connection area with the bore is dimensioned relatively narrow and just so much area that the holding means, for example, the screw in the hole fastened or can be tightened with a tool. Conveniently, namely, then in the connection region in which the reinforcing rods end, these mounted relatively close to the housing in order to achieve a straightforward force application from the reinforcing bars in the retaining bolt or the holding means. Moreover, results from such a configuration, a relatively space-saving construction of the mounting foot, which allows to use the mounting foot even with relatively small precast concrete elements or other elements.

It is favorable that the housing has a cover plate or surface which rests on the side surface. This creates a connection area which is protected on several sides before the entry of concrete during the manufacture of the precast concrete part. But it is also possible on the cover plate a reinforcing rod (for example screwed in a screw or welded) end, which is achieved by the holding forces are impressed by this reinforcing rod in the mounting foot, almost straight on the retaining bolts or the holding means which is in the bore, is transmitted.

When mounting the device to the first element is provided that in the device (with or without housing) a body is adjusted, which covers the bore. The body, which is designed, for example, as a polystyrene body, serves as a formwork element and avoids that the still liquid concrete runs in particular in the hole in the base and this closes and makes unusable. After the preparation of the element, the body is simply removed, whereby the cavity is formed in the region of the connection area and releases the bore.

The invention also relates to a column foot, which consists of two or more mounting feet, as described above. It is provided that the mounting foot this column foot is arranged in particular in the corner or angular region of the element or the support. Assuming, for example, a support with a substantially rectangular cross-section, as in each corner of this cross-section, a mounting, as described, arranged and achieved on the one hand as uniform as possible attachment and on the other hand, a homogeneous as possible passing the holding forces in the support or precast concrete reached , It is possible that the individual mounting feet are connected to each other, for example, by a common plate or struts or the reinforcing bars are mutually arranged so that arranged at their respective ends a mounting foot and so the column base, as described, result.

Furthermore, the invention also relates to a building, in particular a hall with ties resting on supports, wherein the supports are supported by foundations and in particular the components support, binder and / or foundation as a concrete part or precast concrete part are formed, and with the aid of the aforementioned column foot or the device, optionally also angle stiff, are connected to each other. The use of the invention is not limited to the connection of vertically stacked components, but may extend in the same way also to the connection of angularly abutting components, such as the resting of a binder on a support. Of course, it is also possible in the same way, with the inventive design of the device to realize a connection of horizontally oriented or otherwise angularly adjoining components. A great advantage of the invention is that they can also be fixed in an angle-rigid relationship to one another and thus, for example, result in a stiffening framework.

It should be noted that the device according to the invention is not limited to the field of application of concrete components, either as concrete elements manufactured from in-situ concrete or precast concrete parts, but that the device in the same way for joining components made of other materials such as wood, Steel and so on can be used.

The device of FIGS. 5a . 5b . 7, 8 and 10 is not according to the invention.

In the Fig. 1, 2 the different forces principles are shown. In Fig. 2 is the embodiment of the prior art, in particular according to the German Offenlegungsschrift 195 14 685 explained. The basic structure of the device results from a base plate 53, which has a bore 48 into which a holding means 4 can be inserted. At the in Fig. 2 shown embodiment extends at right angles on the base 53, a side surface 51 to which the two substantially identical reinforcing bars 32 are arranged as load-bearing rods 32. According to the aforementioned prior art, when the device is loaded, the following results: The load-bearing bars / reinforcing bars 32 are loaded in tension upward, according to the arrow 30. About the holding means 4, the fastening force and optionally the weight down, according to the arrow 40 ', derived. Due to the offset between the effective direction of the force 30 and the force 40 'creates a tilting moment in the clockwise direction. With 34, 35, the opposing forces are indicated that are necessary to compensate for this overturning moment. In this case, the counterforce 34 is arranged on the side surface 51 in the upper region and the counterforce 35 on the side surface 51 in the lower region.

In contrast, according to the inventive solution Fig. 1 indicated that substantially parallel to the longitudinal extent of the reinforcing bars 32, 32 'from the component, the otherwise not shown, a surface pressure 33 acts on the base 53 or optionally on the device. Due to the configuration, the formation of a tilting moment, as in Fig. 2 shown, avoided. The direction of the surface pressure of the surface force 33 is optionally also parallel to the clamping direction 40 of the holding means 4. It results according to the inventive solution Fig. 1 in that the use of a side face 51, which is necessary for compensating or absorbing the transverse forces 34, 35, in the embodiment according to Fig. 1 can be completely dispensed with. The side surface can actually be reduced to the function of a lost formwork part. In the design of the surface pressure 33, it should be noted that this is the compensation forces from the component which are directed counter to the prevailing forces. As a result, the base plate 53 is supported on the component via the end projecting beyond the rebar 32 'with the smaller diameter to the left. This end is located inside the component, the holding means 4 is easily accessible outside, in the edge or corner of the component. On the use of a proposed by the prior art complex anchoring piece can be completely dispensed with, the installation of the device according to the invention takes place reliably in any case, since no additional measures to protect against tilting must be taken.

In Fig. 3a, 3b is the after Fig. 1 shown in more detail inventive device shown in more detail. Fig. 3a shows a front, Fig. 3b a rear view. In contrast to the embodiment according to Fig. 1 has Fig. 3a, 3b at right angles to the base upstanding side surfaces 51, 51 'on. The side surfaces 51, 51 'with each other are also arranged approximately at right angles and each formed in one piece. They do not form a rigid construction. In the angular range, ie in the connection area between the two side surfaces 51, 51 ', the reinforcing bar 32' is arranged. According to the load applied to it, it is made thinner than the load bearing rods 32 carrying a larger load, which are arranged centrally upward with respect to the respective side surfaces 51, 51 '.

Without the reinforcing bar 32 ', a gap would remain between the two side surfaces 51, 51'. In the illustration selected here, the load-bearing rod 32 'is welded to both side surfaces 51, 51', which of course provides a good mechanical connection, but this is not structurally necessary; it is also sufficient to fasten the reinforcing rod 32 'provided in the angular range only on one side ,

In Fig. 7 is indicated that there is a gap 500 between the two side walls 51, 51 '. In contrast, in Fig. 8 a side surface 51 shown as part of the housing 57, which is integrally formed, L-like angled.

In the Fig. 4, 7 and 9 are presented different, alternatively usable screw.

At the solution after Fig. 4 in the device according to the invention in the base plate 53, a bore in the outer region 61 is provided. In this hole, a screw 502 is performed with screw head back, such that the threaded portion protrudes from the plane of the base 53 upwards. The reinforcing rod 32 has at its one end a sleeve 301 with internal thread, which cooperates with the thread of the screw 502. This makes it possible, in a simple manner, according to the calculated, or constructively predetermined loads different load-receiving rods 32, 32 'to attach to one and the same base 53.

In addition to this configuration is in Fig. 7 instead of the plugged Bolt 502 provided a bolt 503 with external thread, which engages in the screw sleeve 301. The bolt 503 is welded, for example, in the base. In Fig. 9 an inverse principle is proposed, wherein at an open end of the reinforcing bar 32, an external thread 300 is provided, which is screwed into a bore with internal thread 501 in the base 53.

The gap 500 is thereby dimensioned so that the infiltration of concrete, according to the toughness of the concrete, is omitted. Optionally, in the gap 500, a non-illustrated sealing body, for example made of polystyrene, are inserted.

In Fig. 10 is, similar to the construction Fig. 3 , a reinforcing bar 32 is secured to the side surface 51 by a fillet weld 56. The reinforcing rod 32 carries at its upper end a sleeve with internal thread, in which a further reinforcing rod 32 ", with external thread can be screwed.

In the solutions FIGS. 11 and 12 are still proposed different, in particular by welding connection realized solutions of the device according to the invention.

In Fig. 11 is particularly indicated that the housing 57 here from three, with each other arranged gap, each angled oriented side portions 51, 51 ', 51''is formed. Of course, it is possible, according to the calculated load, to provide a small number of reinforcing bars 32 here, due to the angled design of the side parts 51, 51 ', 51 "of each of the individual side parts 51, 51', 51". relative to each other, it is possible to design the connection area 60 as closely as possible and at the same time to make the housing relatively simple, since the use of a cylinder jacket bent Side part is relatively expensive. This makes it possible to arrange the reinforcing bars 32 as close to the bore 48 and thus to minimize the occurring eccentricity of the forces acting, whereby the cost of training the opposing forces is also reduced. As a result, this results in a simpler and smaller device according to the invention. The side parts 51, 51 ', 51 "abut each other at an angle of 45 °. It is also possible to arrange more than three side parts.

According to the invention it is provided that can be dispensed with the arrangement of a housing, or side walls which form such a housing, as for example in Fig. 12 is indicated. For the connection of the secondary reinforcing bars is here, similar to in Fig. 8 Another reinforcing bar is welded to the load-bearing bar arranged in the base plate 53. For covering the bore 48, a body not shown is provided.

It should be noted that the embodiments shown in the various figures are arbitrarily combinable with each other, that is, the various variants of arrangements of housing or side surfaces and the use of Schraubbeziehungsweise welded joints are arbitrarily interchangeable and also disclosed.

In Fig. 5 a, 5 b are shown in two views, an embodiment of the mounting foot. As described, the mounting foot is combined, for example, with other mounting feet together to form a column foot. Usually, the mounting foot 44 is in the corner region of an element, for example, the support of a precast concrete support.

The mounting foot 44 consists of a base 53 which is formed substantially flat, square, has rectangular or round cross-section and has a thickness which is formed so that the base surface as such is resistant to bending. It is usually made of metal, for example iron or steel or structural steel. On the base 53, erected substantially at right angles, side surfaces 51 are provided which form a housing 57. In this case, two side surfaces 51, 51 'are provided, which in turn abut each other at right angles and thus subdivide L-like the base surface 53 into two regions, namely the connection region 60 with the bore 48 and the connection region 61. For connecting the housing 57 with the base 53, a weld seam 49 is provided. This is arranged in the connection example 61 in the example shown here, but it can also be arranged on the other side of the side surface 51, in the connection region 60. However, it is more favorable to make the connecting region 60 relatively narrow and thereby bring the reinforcing rods as close as possible to the bore, which would then interfere with a weld seam 49 in the inner region, ie in the connection region 60.

Since, as described, the mounting foot 44 is arranged in the corner region of an element, a chamfer 58 is provided, which cooperates favorably with a phase at the edge of the precast concrete part. It follows, therefore, that the connecting portion 60 is located at the edge of the precast concrete part and thus the best possible accessibility of the bore 48 for screwing / securing a retaining means 4 (screw, bolts, bolts for welding and so on) allowed.

In the embodiment shown here, several, in particular four reinforcing bars 32 are indicated, which extend relative to the base 53 substantially at right angles to the top. The reinforcing rods 32 are welded in the connection region 61 by welds 56 on the side surfaces 51, 51 '. Depending on the load (size of the force to is transferred) here are a few or more reinforcing rods 32 to order. The reinforcing rods 32 are in this case connected in the connection region 61, whereby it is possible to form the connection region 60 relatively narrow. Alternatively, it is also possible to arrange the reinforcing rods 32, for example, in the connection region, in which case, of course, the screwing of the screw or of the holding means 4 into the bore 48 may be made more difficult. The relatively simple construction of the housing 57, as shown here, two side surfaces 51, allows a practical subdivision into the terminal area and in the connection area, with the selected arrangement, the reinforcing bars 32 are brought so close to the axis of the bore 48 that on additional means for absorbing any transverse forces (which exist due to the offset of the direction of force in the reinforcing bars 32 in relation to the arrangement of the holding means 4 in the bore 48) can be dispensed with. This results in a very simple embodiment of the mounting foot 44th

In a further development of the invention, it is also provided to arrange the reinforcing bars 32 on the side surface 51 and the housing 57, respectively, so that the force resulting from a plurality of reinforcing bars 32, which is transmitted, is aligned as far as possible with the axis of the bore 48, whereby a possible sliding or tilting force is avoided. In Fig. 5 a is shown that the housing 57 is formed of two mutually perpendicular abutting side surfaces 51, cube-shaped. In Fig. 3 c Alternatively, a portion of a lateral surface is shown, through which the reinforcing rods 32 can be positioned even closer to the bore 48.

In Fig. 6 is still shown that in addition to the weld 56 and screw sleeves 55 are provided, which are for example placed on the base 53, for example, welded, wherein the lower ends of the reinforcing bars 32 are provided with a thread 33 which engage in the internal threads of the screw sleeves 55. As a screw not only a patch on the base 53 sleeve is considered here, it is also possible to see a cut into the base 53 thread as a screw, in which case conveniently the base 53 has a sufficient thickness.

The volume, which is enclosed by the housing 57 in the connecting region 60, can also be covered with a body, not shown, when setting in the fastening foot in the precast concrete part, in order to ensure the free accessibility of the bore 48.

The advantages of the high variability of the use of a screw connection and the modular construction of a complete system of devices or mounting feet are also described with regard to a stand-alone protection of this disclosure.

This makes it possible, with a small set of components, according to the requirements, to realize any devices.
