Description

Device for connecting two components as well

modular carrier construction

The invention relates to a device for connecting two, in particular plate-shaped, components by means of a tongue and groove joint, wherein the components to be joined have a groove. Another object of the invention is a device for connecting two components by means of a tongue and groove Vexbindung, wherein the components to be connected comprise a spring. A third object of the invention relates to a modular support structure, in particular bridge, with side elements which are connected to one another via carriers, wherein support elements are arranged on the supports. The connecting device according to the invention can preferably be used in a modular support structure, such as a deployable bridge. The components of a deployable bridge are usually spent separately to a site. On site, the loose components of the bridge are then connected to each other.

Such a bridge is known for example from DE 197 1 300 A1. This bridge has plate-shaped side elements, which are interconnected via transverse elements. The plate-shaped cross members also represent the running surface of a traffic route. For reasons of stability, the transverse elements must be made massive, so that they have a high weight and are difficult to handle. The transverse elements lie loosely in the longitudinal direction. A tongue and groove connection of the cross elements will not be described.

Tongue and groove joints are commonly used in timber for joining plate-shaped components. As a rule, the components each have a groove on one connecting side. For the positive connection of the two components, a loose spring can be inserted into the grooves of the two components.

However, such groove-spring connections have the disadvantage that a large number of loose connecting elements is required for connecting the components.

The object of the invention is to specify a connection of components which makes it possible to connect the components in a simple manner. In a device for connecting two, in particular plate-shaped, components by means of a tongue and groove connection, wherein the components to be joined have a groove, this object is gel ö st, that on a component carrying the carrier, a connecting element is arranged, which having the spring.

Since the connecting element which connects the two components is arranged on a carrier which carries the two components, no loose connecting elements are required. The components can be inserted into the connecting element on the carrier during assembly and thus be connected to one another in a simple manner.

The connecting element is preferably formed as an integral part of the carrier. In a connecting element, which is arranged integrally on the carrier, in particular molded, is no further loose locking elements are required to connect the two components.

In a structural embodiment of the invention, the components are support elements which rest on the support. In particular, the components can form parts of a traffic route that runs above the carrier. As a component of a deployable bridge, the support elements can form a driving or walking surface. Alternatively, the components can rest on the carrier in such a way that they are arranged laterally of the carrier and / or below the carrier. In a further embodiment, the components close flush to each other. The components can be connected flush so that they rest against each other at least partially on the front side. Furthermore, a common surface can be formed by the outer contour of the respective components, which faces away from the carrier. The common surface of the flush-connected components le can form a usable area, in particular with a bridge a flat traffic route.

The connected, in particular plate-shaped components are shared by a further component - the carrier - worn. Advantageous embodiments of the invention with respect to this carrier will be discussed below:

In a preferred embodiment, the connecting element has a web which connects the spring to the carrier. The web can be firmly connected to the spring and / or the carrier. Furthermore, the web can be designed in the manner of a spacer, by means of which the spring can be fixed at a fixed distance from the surface of the carrier. The height of the web can be adapted to the material thickness of the components in the region of the groove.

In a further embodiment, the connecting element has a T-shaped cross section. The upper, horizontal leg of the T-shaped cross section can be formed by the spring. In the connected components, the horizontal leg of the connecting element can be positively connected to the grooves of the components. The lower, vertical leg of the T-shaped cross section may be formed by the web connecting the spring to the carrier. In the connected state, the vertical leg can be arranged in the region between the end faces of the components. Preferably, a movement of the components in the direction of the groove is limited by arranged on the carrier or on the connecting element side stops. By means of the side stops a lateral movement of the components can be inhibited. The side stops may each abut against a side surface of the connected components substantially perpendicular to the connected one Front side is arranged. By the side stops, a movement of the components in a direction transverse to the end faces on which the components abut each other, and thus in the direction in which the groove extends, be limited.

For side stops, which are arranged on the connecting element, it is particularly advantageous if the side stops are arranged on the end of the spring. The components can be connected to one another in the region of the spring and held in the region of the spring by means of the side stops arranged on the edge of the spring. Moreover, the side stops can be integrally connected to the spring, in particular be integrally formed on this.

In an advantageous embodiment of the invention, the carrier has a recess in which the connecting element is arranged. The recess may be formed in the manner of a recess with a support surface for supporting the components. The width of the recess can be adapted to the width of the components. Furthermore, the recess may be adapted to receive the components along its width. The components can be inserted for connection in the recess. In the region of the recess, the components can be inserted into the connecting element and thus connected to one another.

Particularly advantageous is an embodiment in which the recess is designed such that the components are flush with the carrier. The components can be introduced into the recess. By a flush completion of the components with the carrier, a uniform surface can be formed with the same height. The occurrence of cracks or furrows between the components and the carrier can be prevented. In a further embodiment of the invention, the depth of the recess corresponds to the thickness of the components. The recess can be adapted to the components in such a way that, in the case of connected components, a flat surface results in the transition region between the components and the carrier. As a result, a common planar surface can be formed by the components and the carrier, which can be used, for example, as a traffic route in the case of a bridge.

In a structural embodiment of the invention, the side walls of the recess form the side stops. For side walls of a recess that act as a side stop, no separate side stops need to be provided to limit lateral movement of the components. The side walls can touch the components. Moreover, when the components are introduced into the recess, the side walls can act as a guide for the components.

The components may have a groove whose depth is adapted substantially to half the width of the spring. In connected components, the spring can be arranged in half in the groove of the first component and half in the groove of the second component. In addition, the connected components can rest on a contact surface of the carrier, which extends over the entire width of the carrier. Each of the connected components can rest against the carrier on one half of the contact surface. Preferably, the support is wider than the width of the spring. With a contact surface that is wider than the spring, increased stability of the connection between the arms and / or between the components and the support can be achieved be enabled. The components may abut in the connected state with a region on the support which is larger than the region in which the groove extends. In the foregoing, advantageous embodiments of the carrier have been considered which, at the same time, fulfill both a supporting and a connecting function with regard to the two components. Hereinafter, preferred embodiments of the two components will be described. In this context, the side at which the two components are connected to each other, referred to as the front side. The respective side of the two components, which faces the carrier, is referred to as the carrier side. Components which bear against the carrier are thus connected to one another at the end side and connected to the carrier on the carrier side.

It is advantageous if a coupling element which has or forms the groove is arranged on the components in the region of the connection on the front side and / or on the carrier side. The coupling element may be integrally connected to the component. At the front side of the components, the coupling element may be formed as an extension of the component. In a carrier side arranged on the component coupling element, the coupling element may protrude in the manner of an essay on the surface of the component.

Preferably, the depth of the groove with respect to an upper side of the component is different from the depth of the groove with respect to an underside of the component opposite the upper side. The underside of the connected component may face the carrier and in particular rest on the carrier. By means of a groove with material protrusions of different lengths, it is possible on the upper side of the component to make a flush connection of the components. _ while at the bottom of the component in the area below the groove a clearance for the web can be kept.

In a carrier having a recess, the coupling element is preferably located in the recess. In the connected position, the components le frontally abut each other, while the coupling elements of the components are connected to each other in the recess of the carrier.

In a further embodiment, a plurality of coupling elements are arranged in parallel on both components. The coupling elements can be distributed over the front side of the components. Furthermore, guide elements can be provided between the parallel coupling elements, which effect a guidance of the components against each other. In an alternative embodiment, the groove extends over the entire width of the components. Such a groove may be in engagement with the spring over the entire width of the component. This allows a high strength of the connection against tilting of the components against each other.

Components which are connected to one another by means of a tongue and groove connection can, as described above, have a groove on the connection side. The required connecting element in this case has a spring which can be inserted into the grooves of the components. Without changing the principle of the tongue and groove connection, a spring can be arranged on the connection sides of the components in contrast to the above embodiments. In this case, a connecting element is required, which has a groove. In a device for connecting two, in particular plate-shaped, components by means of a tongue and groove connection, wherein the components to be joined have a spring, the above object is thus el ö st, that arranged on a component carrying the carrier, a connecting element is, which has the groove. Since the connecting element which connects the two components is arranged on a carrier which carries the two components, no loose connecting elements are required. The components can be inserted into the connecting element on the carrier during assembly and thus be connected to one another in a simple manner.

Moreover, the advantageous embodiments described above, which have been described in connection with the device in which the connecting element comprises a spring, are equally applicable to a device in which the connecting element has a groove.

The described devices for connecting two, in particular plate-shaped, components allow easy assembly of the components. The components can be easily inserted into the connecting element. By means of the component connection, a surface can be constructed from a plurality of, in particular plate-shaped, components. The devices can be used, for example, for fastening floor coverings or ceiling elements as well as for connecting the components of a support structure.

The carrier can also be formed by a surface, in particular a floor or ceiling surface. On the surface a plurality of connecting elements can be arranged, which are spaced apart from each other. The elements can be connected to the surface by a detachable connection, in particular a screw connection, or by a non-detachable connection. In the case of a carrier designed as a surface, the components can rest against the surface from below. Scaffolding, buildings, roofs, and bridge structures may be implemented as support structures having a plurality of interconnected structural members. In a support structure in the manner of a truss, the components are designed as rods, columns or frames. Furthermore, support structures are known which, in contrast to a framework, have flat, plate-shaped components, as described, for example, in the already mentioned DE 197 19 300 A1.

Regardless of the aforementioned differences in the design of the components, it is advantageous if the support structure is modular. A modular support structure has various types of components and connections in the manner of a modular system. The similar components of one type can be manufactured cost-effectively. Furthermore, the assembly of the support structure can be simplified by similar connections.

In the case of a modular support structure mentioned at the beginning, the abovementioned object is achieved by connecting the support elements as components in accordance with a component connection described above.

Since the connecting element, which connects the two on-laying elements, is arranged on a support which carries the two on position elements, no loose connection elements are required. The support elements can be plugged into the support during assembly into the connection element and thus be connected to one another in a simple manner.

A bridge, which is designed as a modular support structure, may have a plurality of spaced-apart support, which are oriented in the transverse direction of the bridge, ie transverse to the traffic route of the bridge. These transversal ger may wear support elements which are connected according to a component connection described above. The support elements can be made identical and in particular have a groove on two opposite sides. For identical support elements and / or identical carriers on the position elements or the carrier can be interchanged with each other as desired. Thus, during assembly a confusion of components can be excluded.

By means of the described component connection, the support elements can be connected together in the longitudinal direction of the bridge. In addition, the support elements can rest in the region of their end faces on the cross members of the bridge. Thus, the support elements can be connected both with each other and with the cross members. In particular, the end faces of the support elements can rest against each other.

By juxtaposing a plurality of spaced cross members, a traffic area in the longitudinal direction of the bridge can be formed. The spaced cross members may each have a connecting element, by means of which the applied support elements are connected. The component connection can be used as often as desired in series. Depending on the design of the bridge, the support elements can form lane panels or track carriers of the bridge.

In Fig. 1, a relocatable bridge 5 is shown, which is described in detail as an example of a modular support structure. The designed as a trough bridge bridge 5 has different types of supporting components 1, 2, 3, 20, 21, which are configured substantially plate-shaped. The components 1, 2, 3, 20, 21 are components of a modular system in which the components of one type are identical and can therefore be interchanged.

The modular bridge 5 can be used as a temporary bridge structure, which is spent in its components 1, 2, 3, 20, 21 disassembled to its place of use. At the site, the components 1, 2, 3, 20, 21 can then be connected to each other manually. The bridge 5 can be built in a simple manner due to their modularity and the design of the components 1, 2, 3, 20, 21. Further, the bridge 5 can be provided in any length as needed. As a result, in particular, rivers or trenches can be bridged by means of the bridge 5 in a short time. The bridge 5 provides a traffic route for crossing the bridge 5 in the longitudinal direction L, which can be used equally by vehicles and persons.

In the longitudinal direction L, the bridge 5 has as supporting components the side elements 2 which are connected in the longitudinal direction L, in the transverse direction Q are formed by carriers 1 which are spaced apart from one another and will be referred to below as cross members 1, see. Fig. 1. The cross member 1 are connected to the side members 2, 3 by means of a component connection 12, which will be described in more detail below. In the area of the longitudinal ends of the bridge 5, Q is used in the transverse direction as ram arranged 21 trained carriers that facilitate the vehicles and people access to the traffic area. These ramp elements 21 are connected to the side elements 2, 3 via a component connection 12 'and lie on the end-side cross members 1.

The traffic route extending in the longitudinal direction L is formed by the components 20 arranged on the cross beams 1, which are referred to below as supporting elements 20. The support elements 20 are connected to each other by means of the cross member 1 via a connecting device according to the invention, which will be described in more detail in the following text.

The support elements 20 are plate-shaped and can accommodate orthogonal to the forces exerted on the crossing of the bridge 1 forces. In addition, the support elements 20 can also be loaded by forces acting in their plane. The support elements 20 can thus stiffen the bridge against distortion in the manner of a wind union.

The support elements 20 are connected to the cross members 1 via devices described in the text below and form two in the longitudinal direction L of the bridge 5 continuous surfaces, which are particularly suitable as a driving surface for a vehicle, see. Fig. 4. The distance of the support elements 20 is adapted to the average track width of a road vehicle. In order to keep the weight of the bridge 5 low, the support elements 20 are spaced apart from each other in transverse direction, so that two tracks of the bridge 5 formed by the support elements 20 have a material-free gap, which can optionally be covered to allow a safe crossing of the bridge 5 also for pedestrians. The cover can be done for example by a grid. In order to further reduce the weight, the support elements adjoining one another in the longitudinal direction L are Furthermore, elements 20 are also spaced from the side elements 2, 3, cf. Fig. 1 and Fig. 4.

The modular bridge 5 can be assembled in a simple manner from the components 1, 2, 3, 20, 21, since the connecting means for connecting the components 1, 2, 3, 20, 21 fixed components of the respective components 1, 2, 3, 20, 21 are. Thus, no further, loose connection means for connecting the components 1, 2, 3, 20, 21 are required. The components 1, 2, 3, 20, 21 of the bridge 5 are also made of a fiber composite, whereby they have a low weight, in particular less than 25 kg. The components 1, 2, 3, 20, 21 can therefore be held by one person alone and mounted on the bridge 5. When mounting the bridge 5, it is advantageous if the bridge 5 is constructed in segments. A segment 53 of the bridge 5 has two opposite side elements 2, 3, a cross member 1 and two support elements 20, see. FIG. 5. A further segment 53 can be connected to the already constructed segments 53 of a bridge 5 by first connecting the side elements 2, 3 to the already constructed side elements 2, 3. In a further step, the cross member 1 is connected to the side elements 2, 3 of the segment 53 to be attached and locked. Finally, the support elements 20 are connected to form a traffic route m t-den-cross members 1- .J.o_Fjg._5, the cross member 1 is shown only schematically.

Alternatively, the segments 53 can also be prefabricated. For this purpose, the side members 2,3 are first connected to the cross member 1 and locked. In a second step, the rare elements 2, 3 of the prefabricated Segments 53 then connected to the side members 2, 3 of an already connected to the bridge 5 segment 53 and locked. The support elements 21 can be connected to the cross members 1 either before or after connecting the segments 53.

Further, in the assembly of the bridge 5, a clock shift method may be used, in which the segments 53 are prefabricated on one side of the obstacle and interconnected and locked. The built-up segments 53 are pushed in segments over the obstacle. In order to reduce the crimping moments which occur when the constructed segments 53 are moved over the obstacle, a frontal segment 53 is arranged on the foremost segment 53, which can support the constructed segments 53 upon reaching the other side of the obstacle. In the following, the different component connections between the components 1, 2, 3, 20, 21 will be discussed. First, the component connection 12, 12 'between the side members 2, 3 and the cross members 1 and the ramp members 21 will be described. Then the connection of the side elements 2, 3 in the longitudinal direction L is discussed. Finally, the connection according to the invention of the support elements 20 in the longitudinal direction L with each other and with the cross members 1 will be described.

The component connection 12 between the side elements 2, 3 and the cross members 1 will be described below with reference to FIGS. 6 to 9 and FIGS. 27 to 30 for explanation of the structure of the bridge 5. The component connection 12 'between the side elements 2, 3 and the ramp elements 21 takes place in an analogous manner. For the sake of clarity, a simplified embodiment of the invention will be described below for the description of the component connection 12 between the side elements 2, 3 and the cross members 1 Cross member 1 considered, which has no connection means for connection to the support elements 20. These connection means will be described below. The cross member 1 shown in FIGS. 6 to 8 is formed as an elongate, substantially plate-shaped component. The cross member 1 has a body 30, on whose opposite ends fastening elements 6 are arranged. The fastening elements 6 are connected by means of a gooseneck 29 with the body 30, so that a trough-shaped cross-section of the cross member 1 results, see. Fig. 6. At the connection-side ends of the cross member 1 two parallelly arranged fastening elements 6 are provided, which are separated by a groove 26, see. Fig. 7.

The plate-shaped side elements 2, 3 are designed to connect and lock with the cross members 1 about a longitudinal axis L extending, horizontal pivot axis S pivotally, see. Fig. 1. The side members 2, 3 can thus be pivoted individually or in conjunction with the respective adjacent side elements 2, 3 with respect to the cross members 1 and the ramp elements 21 by a pivot angle W, cf. Fig. 2. The pivot angle W is at least 30 °, in particular at least 45 °, preferably at least 60 °.

As shown in Fig. 9, the fastening element 6, 6 'opposite to a vertical direction ^ 7' are placed, which is arranged on the side member 2, 3. The support 7, 7 'on the side member 2, 3 has an inner rounding 33, concentric with the

Swivel axis S of the side member 2,3 extends. Furthermore, the contour of the fastening element 6, 6 'has an inner rounding 33, which is adapted to the inner rounding 33 of the support 7, 7'. The fastening element 6, 6 'is formed in accordance with FIG. 9 such that it engages behind the support 7, 7'. The fastening element 6, 6 'extends against the horizontal direction H via the support 7, 7' and buckles in the manner of a claw in the region of a curvature 31 of the support 7, T from. By Hintergreifung 34, a movement in the horizontal direction H can be blocked after placing the fastener 6, 6 'on the support 7, 7'.

As shown in FIG. 30, the support is designed as an inner section of a recess 10, 10 'on the side element 2, 3. The support 7, 7 'is located in the lower region of the recess 10, 10'. In the rear region, the recess 10, 10 'is bounded by a rear wall 54. Alternatively, the recess 10, 10 'have an opening in the rear region. In the upper region of the recess 10, 10 ', a locking element 8, 8' is provided with a round surface 25, by means of which the fastening element 6, 6 'with the support 7, 7' can be locked. The locking element 8, 8 'is formed as an inner portion 51 of the recess 10, 10'. The contour of the locking element 8, 8 'is adapted to the contour of the fastening element 6, 6' such that the locking element 8, 8 'can be pivoted into the region above the fastening element 6, 6'. For this purpose, the curvature of the circular surface 52 is concentric with the curvature of the outer rounding 32 of the fastening element 6, 6 ', cf. Fig. 9.

Femer-is-in-the Eig._24_dle_AusneJmun_g_10 'is shown. The recess 10 ', as well as the recess 10 on a side of the support 7, 7' arranged stop 9. The stop 9 is formed by a stop surface 37 designed as an inner portion of the recess 10, 10 '. By means of the stop 9, a movement of the transverse support 1 resting on the support 7, 7 'can be limited in a direction parallel to the pivot axis S. Since the supports 7, 7 'and the locking element 8, 8' are arranged integrally on the side element 2, 3, the connection and locking of the components 1, 2, 3, 21 can take place without loose parts. A method for connecting and locking the cross member 1 with the side member 2, 3 will be described below with reference to FIGS. 27 to 29. The method is equally suitable for connecting and locking the ramp element 21 with the side element 2, 3: For connecting the cross member 1 to the side element 2, 3, the fastening elements 6 of the cross member 1 are placed on the support 7 of the side element 2, 3 , In this case, the side member 2, 3 is in an open position in which it is pivoted relative to the vertical direction V by a pivot angle W, cf. Also Fig. 2. When placing the fastening elements 6 engage in the recess 10 a. At the same time engages arranged on the side member 2, 3 nose 10 in the groove 26 between the fastening elements 6 of the cross member 1 a. The nose 10 acts as a stop for the fastening elements 6. This allows a movement of the cross member 1 in the longitudinal direction L and in the transverse direction Q are limited. In addition, further elements can be arranged on the cross member 1, which limit a rotation and / or tilting of the cross member 1 in the horizontal plane formed from the longitudinal direction L and the transverse direction Q.

The connected state, in which the fastening elements 6 rest on the supports 7, is shown in FIG. The fastening elements 6 are located within the recesses 10. The locking elements 8 are located in a position pivoted relative to the cross member 1, laterally of the fastening elements 6. For locking the side members 2 and 3 with the cross member 1, the side members 2, 3 from the open position, see. Fig. 28, pivoted in a locking position in which they are oriented substantially parallel to the vertical direction V, cf. In this case, the locking element 8 is pivoted into the region above the fastening element 6, so that a movement of the fastening element 6 in the vertical direction V is limited. The components 1 and 2 and 3 are locked together in the region of the component connection 12, cf. Fig. 29. In order to block a pivoting movement of the side members 2, 3, the side members 2, 3 can be locked. For this purpose, a securing element 11 is arranged between the end-side side element 2, 3 and the respective ramp element 21 in the region of the ends of the bridge 5. A detailed illustration of this securing element 11 is shown in FIG. 26. The elongate securing element 11 has at its ends in each case a perpendicularly angled bolt 43, 44, wherein the bolts 43, 44 point in opposite directions. The bolt 44 is connected to a arranged on the ramp element 21 connecting element 36 which is formed in the manner of a sleeve, see. Fig. 25. The bolt 44 can be inserted in the longitudinal direction L in the connecting element 36.

At the other end, the securing element 11 is connected by means of the bolt 43 with a terminating element 22, which is coupled to the side element 2, 3 via a connecting element 41. For this purpose, the bolt 43 can be inserted into an opening in the closing element 22 in the longitudinal direction L. By means of this backup inadvertent pivoting of the side elements 2, 3 can be prevented. As will be shown in the further text, the side elements 2, 3 are also lockable in the longitudinal direction L. As a result, only one securing element 11 arranged at the end of the bridge 5 is required to lock the pivoting movement of the side elements 2, 3 which are locked with one another.

In the following, the connection of the side elements 2, 3 will be explained with reference to the illustration in FIG. 24:

In the longitudinal direction L of the bridge 5, the side elements 2, 3 are connected to each other via connectors 13. In the region of the lower chord of the side elements 2, 3, these each have a pin 14 on one end side and a sleeve 13 on the opposite side. Both the pin 14 and the sleeve 13 are arranged concentrically to the pivot axis S. The plugged into the sleeve 13 pin 14 can be rotated. The pin 14 is fixedly connected to the respective side member 2, 3. Thus, the connector 13, the pivot bearing for the side member 2, 3 form.
