Description

Technical area

The invention relates to an arrangement consisting of a first component, a second component and a mounting part for temporarily holding and fixing the first component to the second component, in particular components of a mounting system, referred to in the preamble of claim 1. Art.

State of the art

In steel structures, individual components are connected to each other, for example by means of welding or riveting. These compounds are expensive to produce and a reconstruction of the construction is possible only with great effort. There are constructions known in which the individual components are releasably connected to each other by means of a screw connection.

To improve the flexibility of steel structures so-called mounting systems are used, in which z. B. a carrier is provided with openings at a predefined distance, in which further components of the steel structure can be fastened by means of a screw connection. If the carrier is a closed hollow profile or if the carrier is accessible only on one side, for example, press-in nuts are inserted into the openings and pressed with a special tool. These press-in nuts can have an internal thread into which a screw means for fastening a component to the carrier can engage.

A disadvantage of the known solution is that the openings in the carrier must be matched to the outer diameter of the press-fit nut, so that a rotation of the press-in nut is given to the carrier. Furthermore, the internal thread of the press-fit nut is smaller than the original size of the opening, which is why, for example, in an opening in the carrier with a diameter of 12 mm, only one female thread connection for an M8 screw can be produced. At high loads on the steel structure are for their load transfer large compound cross sections of the fasteners sought to limit the number of necessary fasteners to a minimum.

From the US 3,545,711 A is a clamping device for fixing a suspension hook on a perforated hardboard known. The clamping device comprises two flat parts which each have at one end of an abutment portion an insertion section spaced therefrom and at the opposite end portion of the abutment portion engageable openings for receiving the threaded free end of the suspension hook. The length of the connecting portion between the insertion portion and the abutting portion of the flat parts is formed slightly shorter than the thickness of the hardboard. After insertion of the two flat parts in two separate openings in the hardboard of the suspension hook is passed through the opening of a flat part and screwed into the opening of the second flat part. By means of a nut, the flat parts are brought into abutment with the surface of the hardboard, wherein the flat parts are braced and the suspension hook is held on the perforated hardboard.

Presentation of the invention

The present invention has for its object to provide an arrangement consisting of a first component, a second component and a mounting member for releasably securing a component to another component, which is also used in only one-sided accessible profiles and ensures a high rear grip and a security against rotation , wherein the maximum connection cross-section is made possible at the opening. It should be possible a simple installation without special tools.

The object is solved by the features of claim 1. According to the invention, a mounting part for temporarily holding and fixing a first component to at least one second component, in particular of components of a mounting system, comprises an insertion portion and a holding portion adjacent to the insertion portion. The insertion section has at least one receptacle for arranging a fastening means for fastening the first component to the second component. The receptacle has a collar.

Since the second component is a profile which has openings at a predefined distance on at least one of the outer walls, the receptacle for arranging the fastening means can be arranged on the insertion section such that the receptacle comes to lie at an opening of the second component when the mounting part is inserted in an opening of the second component. The fastening means can be inserted through the opening in the second component and through the receptacle in the mounting part and fixes the two components together. The holding portion prevents the inserted mounting part can fall into the only one-sided accessible component. Furthermore, the holding section can serve as a temporary mounting of the first component until it is fixed to the second component. Especially with mounting systems for heavy loads, eg. As in industrial constructions, the individual components have a large weight, so that the temporary support represents a significant ease of assembly.

The receptacle for the arrangement of a fastening means has a collar. This collar is preferably formed on the, the second component facing side of the mounting part at the insertion portion. With the collar a centering means is provided on the mounting part, since the outer dimensions of the collar are preferably formed smaller than the inside width of the openings in the second component. The collar has, for example, for facilitated centering on its outer surface on a funnel-shaped configuration. If the receptacle for arranging the fastening means has an internal thread, then this connecting thread is preferably formed in the collar. Thus, even with a low material thickness of the mounting part, a sufficient number of viable threads for the screw can be provided. If the centering of the mounting part is of little importance, the collar can also be formed on the side facing away from the second component of the mounting part at the insertion and serves only the local material reinforcement of the insertion to provide a sufficient number of viable threads on the mounting part for the screw.

It is thus provided a lever arm on the mounting part, which facilitates by aligning the holding portion aligning the recording of the mounting part on the position of an opening in the second component. The receptacle is preferably spaced from the setting direction end of the Einsteckabschnitts to provide a bearing surface. If a tensile force acts in the receptacle, this support surface prevents the receptacle from decorating or large moment forces act on the mounting part. The material thickness of the mounting part can be made smaller, which allows an economical design of the mounting part.

Preferably, the mounting member for aligning the, inserted in the profile mounting part, an actuating portion, wherein the actuating portion is arranged at the free end of the holding portion. With the operating portion, the receptacle of the mounting part on the inaccessible side of the outer wall can be pressed firmly against them until the fastener is inserted. The operating portion is aligned, for example, parallel to the plane formed by the male portion, so that the mounting portion has a Z-shaped configuration. The operating section additionally provides a hook-like receptacle on the mounting part inserted into the second component, on which the first component can be temporarily held until it is fixed in a preferred manner.

Preferably, the actuating portion has a greater width than the width of the insertion end. The width of the operating section is greater than the clear width of the opening in the profile. With this design of the actuating portion on the one hand prevents the inserted into the second component mounting part can accidentally fall into this and on the other hand, the handling of the mounting part is improved during setting and fastening process.

Advantageously, the actuating portion is angled relative to a plane formed by the male portion, preferably at an angle of 5 ° to 30 °. As a result, a contact pressure can be exerted on the non-accessible side of the outer wall of the second component, which prevents the mounting part from escaping during insertion of the fastening means. In addition, the mounting of a first component on the mounting part for temporarily mounting the component on the second component is simplified.

Preferably, the holding portion has a height which is at least the material thickness of the outer wall of the second component, for. B. corresponds to the outer wall of the profile. Jamming of the mounting part when inserted into the profile or when aligning the mounting part is largely excluded with this design of the mounting part.

Preferably, the at least one receptacle for arranging a fastening means comprises an internal thread and the fastening means comprises a screw means which can be brought into the internal thread. This creates a releasable attachment of the first component to the second component. Furthermore, the components of the entire steel structure connected in a first step and then the steel structure are directed. Once the steel structure is aligned, all connections are screwed together tightly, or tightened. In a variant of this, the receptacle may be formed as a bore and as a fastening means alternative to said screw means z. B. a blind rivets are arranged.

Preferably, at least two receptacles for the arrangement of at least two fastening means are arranged on the insertion section. Especially at high loads, as z. B. occur in constructions in the industry, the connecting cross section of only one fastener for the load transfer can not be sufficient. The insertion section has a length which extends at least from the opening into which the mounting part is inserted to the next but one opening, so that fastening means for fastening the first component to the second component can be inserted at two adjacent openings of the second component.

Advantageously, the insertion portion has at least two receptacles for receiving at least two fastening means and the holding portion of the mounting part is formed by a fastening means which is arranged in a, at least two receptacles. This embodiment is particularly advantageous if, for structural or aesthetic reasons, the mounting part should not be recognizable from the outside. With the fastening means, which is designed as a holding portion, the mounting part is secured against slipping into the second component and can be aligned via this fastening means in the second component for the arrangement of the at least one further fastening means.

In another, such embodiment of the mounting part, the actuating portion may be formed as a removable part of the mounting part. For this purpose, the actuating portion is releasably connected, for example via a rear handle or a clip with the male portion, or with the holding portion. Once the fasteners are set in the receptacles of the mounting part, the operating portion of the plug-in portion can be removed. The removable actuating portion is made of plastic, for example. Furthermore, the removable operating portion may be formed as a reusable part for mounting other mounting parts, wherein the removable operating portion is preferably also arranged during disassembly of the steel structure on the mounting part, so that the mounting part does not fall into the inaccessible second component after removing the fastening means can.

The mounting part is preferably made of metal as a stamped / bent part. Furthermore, the mounting part can be made of a suitable plastic.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

In the Figures 1 and 2 a first embodiment of a mounting part of the arrangement according to the invention is shown. Fig. 1 shows a perspective view of the mounting part es 1, the a plug-in portion 2, a holding portion 3 and an operating portion 4 includes. In the area of the setting direction end 5 of the insertion section 2, a receptacle 6 is formed with an internal thread 9, which has a collar 7. The collar 7 serves on the one hand as a centering aid and on the other hand, the collar 7 allows the arrangement of a sufficient number of threads of the, provided in the receptacle internal thread to create a viable screw, while lower material thickness t of the mounting part 1. The receptacle 6 is to the settlement end 5 spaced to provide a support portion 8.

The height H of the holding portion 3 corresponds at least to the thickness d of the outer wall of the profile 11 into which the mounting part 1 is inserted. The operating section 4 adjoins the holding section 3. The mounting part 1 has in longitudinal section a substantially Z-shaped configuration, wherein the actuating portion 4 at an angle α of 20 ° with respect to a plane which is formed by the insertion portion 2, angled. The operating portion 4 has a width B which is greater than the width P of the insertion portion 2. This prevents that used in a profile mounting part 1 can fall into the profile.

Fig. 2 illustrates a section through the used in a carrier, according to the first embodiment formed, mounting part. The carrier 11 is in this embodiment, a closed hollow profile. In this illustration, a section of an outer wall of the carrier 11 is shown, which is provided with a plurality of openings (here the openings 12 and 13) at a predefined distance. The openings 12 and 13 are formed as square holes and have a clear width of 13.5 mm. The formation of the openings 12 and 13 as square holes allows easy positioning of the mounting part 1 on the carrier 11 with respect to openings formed as holes, which provide no defined support surface for the mounting part 1. The axial distance A of the openings 12 and 13 is 50 mm in this example. The mounting part 1 is tuned in its dimensions to the dimensions present on the carrier 11. In this embodiment, for example, the width P of the insertion portion 2 is 13 mm and the width B of the operation portion 4 is 20 mm. The distance between the edge of the holding portion 3 to the axis of the receptacle 6 is matched to the distance A between the openings 12 and 13 and is in the illustrated embodiment about 45 mm.

The mounting part 1 is inserted with the insertion portion 2 in the carrier 11 and rests with the holding portion 3 on the lower edge 14 of the opening 12. At the operating portion 4, the component to be attached to the carrier 11, are suspended and is held temporarily until its fixation on the carrier. This is a simple one Assembly of the entire construction also possible with larger and thus heavier components.

With the operating portion 4, the mounting part 1 in the carrier 11 is aligned. When the receptacle 6 comes to lie in the opening 13, a screw 10 is inserted into the receptacle 6. So that the mounting part 1 during the setting process of the screw can not escape, the actuating portion 4 is pressed in the direction of the carrier 11, whereby the insertion portion 2 is pressed against the inner side 15 of the outer wall of the carrier 11. The support section 8 prevents that in a tensile load on the receptacle 6 on the insertion portion 2, a moment load occurs and / or that the arranged in the receptacle 6 internal thread warps due to the load.

In Fig. 3 is a plan view of a second embodiment of the mounting part shown. The mounting part 21 has a plug-in portion 22, a holding portion 23 and an actuating portion 24 and is formed in longitudinal section substantially the same as the mounting part 1. In contrast to the mounting part 1 21, two female threads 29 having and provided with collar 27 receptacles 25 and 26 are provided for two fasteners 10 on the insertion portion 22 of the mounting part. The distance E between the two receptacles 25 and 26 corresponds to the distance between two openings of the carrier, in which the mounting member 21 is used to provide a connection option. Due to the larger cross-section of the fasteners 21 higher loads can be removed with this embodiment of the mounting part, as it is with a single-ended connection according to the in Fig. 1 and 2 shown embodiment of the mounting part 1 is possible.

A perspective view of a third embodiment of the mounting part is in Fig. 4 shown. The mounting part 31 is constructed in two parts and comprises a plug-in section 32 at the ends of which a receptacle 33 or 34 is formed. The receptacles 33 and 34 each have an internal thread 39 and are each provided with a collar 37 for the local material reinforcement of the insertion portion 32. In the receptacle 34, a threaded rod portion 35 is used, which serves as a holding portion for mounting the mounting member 31.

The mounting member 31 is in the only one side accessible component (not shown here) used and aligned by means of the threaded rod portion 35 until the receptacle 33 comes to rest on the opening in only one side accessible component. Instead of a threaded portion 35, a screw with a, provided on the screw head, large washer can be arranged in the receptacle 34, with which the mounting member 31 is aligned on only one side accessible component. With another fastener is the to be connected component fixed on only one side accessible component. The component to be connected can be pushed over the externally accessible end of the threaded rod portion 35 for temporary support.

Instead of a threaded portion 35 can be arranged directly as a holding portion of the mounting member 31 in the receptacle 34 a screw. Preferably, in this variant of the mounting part on the insertion portion 32 a, detachably connected to the insertion portion 32 associated actuating portion (not shown here), which is removable after completion of the setting operation of the mounting member 31 thereof. These embodiments of a mounting part are particularly advantageous if the mounting part from the outside for structural reasons may not project beyond the outer wall of the carrier or should not be visible for aesthetic considerations.

In summary, it should be noted that an arrangement with a mounting member for releasably securing a component to another component has been created, which is also used in only one-sided accessible profiles and ensures a high rear grip and a security against rotation. It is a simple installation of a steel structure without special tools possible. In addition to the application of the mounting part in connections of steel structures, the mounting part can also be arranged in constructions that are made of other materials and have only one-sided accessible components to which other components are connected.
