Description

The invention relates to a holding body for anchoring or fastening an object to a solid wall in civil engineering, civil engineering, water and tunnel construction, comprising a fastening anchor fastened to the wall, wherein a continuous sealing film is arranged between the object to be anchored and the wall, which is connectable to a connected to the holding body film part.

Such a holding body is from the DE 10 2009 016 153 A1 known. This holding body is formed as a piece made of metal nozzle, which has two opposite blind holes. In the blind holes in each case a thread is inserted, in each of which a threaded bolt can be screwed. One of the two threaded bolts can be driven into a wall in a tunnel or inserted into a borehole let into the wall. On the opposite threaded bolt a fastening nut can be screwed, with which an object to be fastened can be attached to the threaded rod. Furthermore, a first plate is welded to the neck, to which a sealing film is applied. The sealing film is clamped between the first plate and a second also held by the mounting nut plate. To install the sealing foil, it must have a hole in order to be able to push the sealing foil onto the threaded bolt to bear against the first plate. The disadvantage is that urgent through the nozzle, for example, in a corrosion of the nozzle Water or other leaking from the wall optionally aggressive fluid can pass through the hole of the film. Thus, a permanently tight lining, for example, a tunnel completed from the tunnel can not be guaranteed.

The invention has for its object to provide a holding body for permanently tight anchoring of an object to a fixed hike in engineering, civil engineering, water and tunneling.

This object is achieved in that the holding body has a connectable to the film part the holding body penetrating separating body. In other words, the separating body divides the holding body into preferably two parts, which however still fulfill or ensure the holding function. The separator thus formed ensures that a permanently tight lining can be ensured with a sealing film, for example a tunnel, since no water or any other liquid can penetrate the separating body even in the case of, for example, conceivable corrosion of the holding body due to the separating layer. It should be noted that, for example, during the construction of a tunnel initially a tunnel is driven into, for example, a mountain. This tunnel is lined with a sealing film to prevent penetration of, for example, the mountain emerging water in the tunnels and the later tunnel. At the same time during the construction phase of the tunnel on the wall of the tunnel objects, such as an iron reinforcement, pipes, rails or lines to be attached, which can be removed except for the iron reinforcement in front of the lining of the tunnel with a concrete layer again. However, the holding bodies connected to the sealing film remain in the tunnel. The inventive design now a permanently tight lining of the finished tunnel is guaranteed. It is the Subject of the invention in all conceivable types of engineering, civil engineering, water and tunneling applicable.

In a further development of the invention, the holding body on two holding parts, each having at least one holding tooth, which are hooked without contact. By this configuration, the separating body, which will be discussed later, penetrate the holding body completely and without interruption by the separating body is arranged along the free space formed by the contact-free entanglement. The separating body is also guided on the outer circumference of the holding body at least up to a front end of the holding body or a holding part to be connected there directly or indirectly - as will be explained later - with the sealing film.

In a further embodiment of the invention, the holding part on a one-sided threaded channel, in which a thread is inserted. In the thread, for example, a fixing anchor can be screwed, which can be driven into the hike or inserted into a wall recessed bore hole. In the thread of the opposite holding part, for example, a threaded rod can be screwed to the example, temporarily an object, such as a pipe, a rail or a pipe, during the construction phase, for example, the tunnel can be attached. Instead of the threaded rod, for example, an eye having a bolt can be screwed into the thread of the second threaded channel, in which case the eye is used to attach the object. The article is usually removed prior to concreting the stud. The article may also be the said iron reinforcement, which must be secured in the tunnel before installing the formwork for casting the concrete pipe. As an alternative to the attachment using the threaded channel with the thread embedded, the fastening anchor, the threaded rod and / or the bolt can also be formed integrally with the respective holding part.

In a further development of the invention, the holding part is cylindrical and has on one side the at least one also a cylinder base shape having holding tooth on. The thus formed from two holding parts with inclusion of the separator body body builds very slim and can thus be easily used even in confined spaces.

In a further embodiment of the invention, the holding part has at least two holding teeth in the form of a respective one in the inner tooth and an outer tooth, which are arranged on opposite ends of the holding part. The holding body is formed by two so-formed holding parts are hooked without contact, wherein the at least one inner tooth of the first holding part in the at least one outer tooth of the second holding part and the at least one inner tooth of the second holding part are inserted into the at least one outer tooth of the first holding part , In order to keep the surface pressure of the enclosed separating body, which is also arranged here along the free space formed by the contact-free entanglement, small, it is provided according to the invention to arrange a plurality of juxtaposed inner teeth and outer teeth on a respective holding part. For example, a preferred embodiment of a holding part in each case has six inner teeth and six outer teeth.

In a further development of the invention, the at least one outer tooth is arranged on a threaded tube receiving the cylindrical tube section of the holding part. In yet another embodiment, the cylindrical pipe section merges into a pipe part forming a semicircle, wherein at least one internal tooth is arranged in the pipe part. In this case, the transition from the pipe section into the pipe part can be reinforced, for example, with struts. This embodiment has proven to be particularly advantageous and easy to produce. When the two holding parts for forming the holding body with the insertion of the separating body are joined together, the two cylindrical pipe sections of the two holding parts on a common center line, so that tensile forces acting in the holding body after installation in, for example, the studs are transmitted without generating transverse forces.

In a further embodiment of the invention, the inner tooth and the outer tooth are each formed semicircular. This embodiment ensures a good power transmission of the toothed holding parts and a low surface pressure of the inserted separating body. In the context of the invention, however, the pipe section, the pipe part, the internal tooth and the external tooth can also have almost any other coordinated shapes, for example a rectangular or a polygonal shape.

In a further development of the invention, the separating body is a molded between the hooked holding teeth of two holding parts or otherwise introduced plastic. As plastic is polyamide (PA), polyethylene (PE), polyvinyl chloride (PVC) or an alloy of various plastics in question. The plastic of the Trennköpers must harmonize only with the inclusion of a subsequently defined film plate (if present) and the film part ultimately with the plastic of the sealing film so that they permanently and reliably connected to each other, for example, glued or welded. The separating body preferably has such rigidity that it does not deform even when a tensile force of up to several tons is applied to the holding body of the separating body.

In a further development of the invention, the material of the holding part is a metallic material or optionally also a plastic material. Preferably, the holding part may be made of cast steel or VA cast. In a production of plastic, for example, polyamide or polyethylene or else an alloy of the two plastics mentioned or with at least one of the two plastics come into question.

In a further embodiment of the invention, the separating body is connected to an end of one of the two holding parts arranged on the film plate, which in turn is connectable to the film part or directly forms the film part. The film part is in turn connected to the sealing film, for example, welded using hot air. The film part is connected with the inclusion of the optional film plate with the separating body in the production of the holding body, while the film part is connected to the site with the sealing film, in particular glued. The film plate is preferably rigid and can be made of the same material as the separator and made simultaneously with this, while the film part is elastic, in order to allow trouble-free pressing against the sealing film during bonding, especially in a non-planar wall. The film part is preferably made of the same material as the sealing film.

In a further development of the invention, a holding disk is also pushed onto the holding plate with the inclusion of the film part in the manufacture of the holding body to the plant plate to the plant. This embodiment allows a tight connection of the film tray with the film part, which is particularly durable. In addition, the film part can be glued to the film plate and / or the retaining disk.

In a further development of the invention, a trained as a steel tube sleeve is placed on the interconnected holding parts. This embodiment is used in particular in the slender cylindrical holding body. This embodiment increases the transferable from the holding body lateral forces. The steel tube may also have a plate-shaped edge, which replaces or forms the retaining disk.

Further advantageous embodiments of the invention are described in the drawings, are described in more detail in the embodiments illustrated in the figures of the invention.

FIG. 1 shows a wall 1, which is for example a built into a mountain tunnel, which is to be expanded into a tunnel. However, the wall 1 can basically be any wall in civil engineering, civil engineering and / or hydraulic engineering.

However, the wall 1 of the stud is preferably formed by a rock of the mountain or a concrete layer that has been applied after the incorporation of the stud in the rock of the mountain on the rock, for example, has been sprayed. A concrete layer solidifies the rock and compensates for sharp-edged bumps in the tunnel. The wall 1 is after their Completion lined with a sealing film 2 by the sealing film 2 is fixed to the wall formed by the stone or the concrete layer 1, for example by means attached to the wall 1 Rondellen. The sealing film 2 consists of interconnected, for example glued, film webs that ensure reliable sealing of the tunnel against existing in the mountain water or other possibly aggressive fluids. The material of the sealing film 2 is a rot-resistant plastic, wherein the sealing film 2 has a thickness of preferably 2 to 3 mm.

To attach to the wall 1 any objects, such as an iron reinforcement, pipes, electrical installations or support, an inventive holding body 3 is provided. For example, the iron reinforcement is complained before retracting a formwork-carrying formwork carriage in the tunnel, wherein the then iron-insulated formwork space is filled with concrete. The holding body 3 is thus used, for example, for fastening the iron reinforcement to the wall 1 which is lined with the sealing film 2. After removing the formwork elements, the finished tunnel tube is formed in the mountain. In order to fasten the holding body 3 to the wall 1, the holding body 3 or a fixing anchor 4 holding the holding body 3 on the wall 1 must penetrate the sealing film 2. In conventionally designed holding bodies 3, a leak is thereby created, at least in the long term, through which water or any other possibly aggressive liquid can penetrate from the mountain into the tunnels or later into the finished tunnel.

The fastening anchor 4 is inserted into, for example, a hole 5 incorporated through the sealing film 2 into the wall 1, for example by gluing. On the thus secured in the wall 1 mounting anchor 4, the inventively designed holding body 3 is screwed. For this purpose, the holding body 3 or a holding part 6a of the holding body 3rd a one-sided threaded channel 7a (see FIG. 2 ), in which a thread 8a is inserted. In a connected to the first holding part 6a holding part 6b is also a threaded channel 7b is inserted, which also has a thread 8b. In this threaded channel 7b and the thread 8b, for example, an eye having a bolt 9 is screwed to which the iron reinforcement or the other object can be attached.

The holding part 6a is connected to the holding part 6b to include a separator body 10 penetrating the holding body 3. This will be detailed in the description of the FIG. 2 explained. The separating body 10 is connected to a one-sided holding part 6 a arranged film plate 11 which is connectable to a film part 12 or the film part 12 forms. The film part 12 is connected during assembly of the holding body 3 on the wall 1 with the sealing film 2, for example glued. Since the separating body 10 completely penetrates the holding body 3, it is thus ensured that a permanently sealed and continuous seal is produced along the wall 1. It should be noted that the sealing film 2 and the separator 10 are made with the inclusion of the film plate 11 and the film part 12 of a plastic that is permanently resistant to water or other potentially aggressive liquids. In this context, the material (usually cast iron) of the fastening anchor 4 and the at least first holding part 6a plays a minor role. This means that they do not necessarily have to be durable in relation to the water or the aggressive liquid, since the fastening anchor 4 and the at least first holding part 6a have no function after the completion of the concrete tube of the tunnel.

Evidently the FIG. 2 the holding body 3, the mentioned holding parts 6a, 6b, which are hooked together without contact. For this purpose, the first holding part 6a and the second holding part 6b respectively a number of holding teeth formed as inner teeth 13 and outer teeth 14 and disposed at opposite ends of the respective holding part 6a, 6b. Each inner tooth 13 and each outer tooth 14 is, which is also the perspective view FIG. 3 can be seen, formed semicircular. The inner teeth 13 are arranged on a threaded channel 7a, 7b receiving cylindrical tubular section 15 of the holding parts 6a, 6b. The pipe section 15 merges into a semicircle-forming pipe part 16, in which the inner teeth 13 are arranged. The transition from the pipe section 15 to the pipe member 16 may be reinforced with struts, for example. In the case of the retaining body 3 designed according to the invention, six inner teeth 13 and six outer teeth 14 are present in each case. However, any other number of internal teeth 13 and external teeth 14 may also be provided. The holding parts 6a, 6b are preferably made of a metallic material, in particular a cast iron.

The holding body 3 with the hooked together holding parts 6a, 6b is formed by a holding part 6a is joined to the other holding part 6b so that the inner teeth 13 of the first holding part 6a engage in the outer teeth 14 of the second holding part 6b for producing the non-contact connection and vice versa. Between the holding parts 6a, 6b so interlocked, the separating body 10, which preferably consists of a sprayable plastic, is preferably injected and is guided on the outer wall of the holding body 3 thus formed at least to an end face of the holder body 3. At the front end of the holder body 3, the separating body 10 is connected to a foil plate 11 or passes into this foil plate 11. The film plate 11 is in turn connected to the film part 12, which is finally adhered to the sealing film 2. The sealing film 2 is in the FIG. 2 to illustrate the functional interaction with the film part 12 without the wall 1 shown.

FIG. 3 shows a perspective view of the previously described holding body 3. Accordingly, the description of the FIG. 2 directed.

The holding body 3 according to FIG. 4 is different from that of FIG. 2 in that here the holding parts 6a, 6b each have only one holding tooth 17a, 17b, which are hooked together without contact. This holding body 3 is formed overall cylindrical, wherein the retaining teeth 17a, 17b have a cylindrical basic shape. Also in this embodiment, the separator 10 is the holding body 3 penetrating into the parting line formed by the retaining teeth 17 a, 17 b and injected or molded on the outer circumference of the holding body 3. In the illustrated embodiment, the film part 12 is attached to the outside of the film plate 11, for example, glued. To stiffen the holding body 3 thus formed, a sleeve 18 designed as a steel tube can be slid or pressed onto the holding body 3 thus formed.

The holding body 3 according to the FIG. 5 is largely similar to that of FIG. 4 educated. In this embodiment, essentially only the film plate 11 is formed differently and the film part 12 is pressed against the inside of the film plate 11 adjacent to an impressed on the outer periphery of the holding body 3 holding plate 19 close to the film plate 11 optionally with additional bonding. Also in this embodiment, designed as a steel tube sleeve 18 is pushed or pressed to stiffen the holding body 3 on this. The sleeve 18 may additionally adjacent to the film plate 11 have a plate-shaped edge, which forms the retaining disk 19 for pressing the film part 12 to the film plate 11 or replaced.

Finally, it should be noted that in the context of the invention of any features of the various embodiments can be combined with each other and with each other.
