Definitions

  • the invention relates to a connecting fitting for connecting two components on two flat connecting surfaces facing one another.
  • the joint is used in building construction to anchor a vertically oriented face of a horizontally oriented timber beam to a planar joint surface of another structural member oriented parallel to the face.
  • the generic construction is exemplified by the DE 202 18 592 U1 explained.
  • the connecting surfaces of the two components to be connected are vertical, parallel to one another and facing one another.
  • the connection fitting comprises two flat fitting parts and screws which run through a flat fitting part into one of the components to be connected in order to rigidly anchor the respective flat fitting part to the respective component.
  • the two flat fitting parts are held together by a so-called dovetail connection.
  • the first flat fitting part has a groove running parallel to its plane, which is open in the longitudinal direction towards a side edge of the surface of the fitting part and whose cross-sectional width is greater at the bottom of the groove than at the groove opening.
  • the second planar fitting part has an elongate raised projection parallel to its plane, the cross-sectional width of which is less at the base of the projection than at the region remote from the base.
  • the width of the raised portion of the cross-sectional area of the protrusion is greater than the width of the cross-sectional area of the groove at the groove opening.
  • the flat fitting part having the groove is fixed to the stationary component in such a way that the open end face of the groove is at the top and the opening surface of the groove is facing away from the stationary component.
  • the second flat fitting part is mounted on the component that can still be moved in such a way that the raised, elongated projection faces away from the component that can still be moved.
  • the still movable component is then lowered along the stationary component in such a way that the projection on the second flat component slides into the groove on the first flat component until the lower end face of the projection rests against the lower end face of the groove.
  • the complementary assembly method can also be realized without disadvantages, in which the fitting part having the groove is mounted on the movable component with the end face of the groove open towards the bottom and the fitting part having the projection is mounted on the stationary component.
  • the EP 2093 334 B1 also shows a generic design.
  • the two flat components are fixed to one another in addition to the dovetail connection by a screw, which extends in a screw channel that runs parallel to the longitudinal directions of the groove and projection, with a portion of the length of the screw channel in the flat part having the groove Component runs and in the longitudinal direction of the screw channel subsequent further section in the projection having flat component.
  • the EP 1 764 447 A2 shows a connecting fitting for connecting two components to two flat connecting surfaces facing one another, the connecting fitting comprising two profile parts, each of which has a hook-shaped curved profile wall, and a number of screws.
  • the two profile parts are attached to one of the components to be connected by means of screws that pass through the profile parts anchored running perpendicular to their profile direction, and the hook-shaped curved profile walls are mutually hooked.
  • the interlocking is fixed by a screw, which runs parallel to the profile direction of both profile parts in the volume area encompassed by both hook-shaped profile walls and bears against both hook-shaped profile walls.
  • the relatively low static load capacity of the connection fitting is problematic.
  • a component is a horizontally arranged beam made of wood and one end face thereof is a connecting surface, to align the required screws at an angle relative to the longitudinal direction of the beam.
  • a disadvantage of the construction described is that the respective pairs of fittings either only fit well for a precisely determined cross-sectional height of the beam, or that a number of relatively small pairs of fittings are required for a single component connection must be used, which must be mounted on the connecting surfaces at intervals one above the other. This leads to a loss of effective connection surface and difficult to meet accuracy requirements when positioning the fittings and often difficult to perform maneuvers when mounting the beam.
  • the object on which the invention is based is to improve the described construction in such a way that it can be better adapted to connecting surfaces of different heights and still allows simple and statically correct assembly.
  • the connecting fitting to be arranged between the mutually parallel and vertically aligned connecting surfaces has two mutually complementary fitting parts, namely a groove fitting and a tongue fitting, each of which is rigidly anchored to the respective connecting surface of one of the components to be connected, the groove fitting having a groove which is only open on one end face and whose flanks (lateral Boundary surfaces of the groove) have an overhanging surface area and the tongue fitting has an elongated projection also referred to as a "tongue", the two lateral flank surfaces of which also each have an overhanging surface area, with the longitudinal directions of the tongue and groove parallel to one another (usually vertical) in the installed position are aligned and wherein the tongue is pushed into the groove in the longitudinal direction and protrudes with its two lateral flank surfaces into the area covered by the overhanging flank surfaces of the groove.
  • overhanging surface area means that the groove has a cross-sectional area in which the groove depth increases as the width of the groove increases.
  • overhanging surface area means that the cross-sectional area of the profile-like elongate projection constituting the tongue has a region in which its width increases with increasing distance from the root region of the protrusion. So in these uses of the word “overhanging” it doesn't matter how the tongue or groove is actually arranged in space.
  • both the groove fitting and the tongue fitting can be assembled very easily as a straight line of fitting members, with a larger or smaller number of fitting members being used as required.
  • the fitting members are aligned with one another in such a way that the screw channel extends in a straight line through all the fitting members.
  • a space-saving design is possible because several similar fitting elements can be mounted directly adjacent to one another on a connecting surface of a component, and the precise alignment of the fitting elements to one another is simple.
  • the common contact surfaces of fitting elements of the same type to be arranged on one another are preferably not simply formed flat, but rather they have surface structures which are complementary to one another, so that they only rest snugly on one another when they are in the optimal relative position. This means that the fitting elements can be easily brought into the optimal position relative to one another, as in the case of a snap-in or plug-in connection, without additional aids during assembly, since they have stop surfaces against one another in at least one direction for each degree of freedom of movement to prevent unwanted displacement.
  • two of those screw channels are provided for each pair of groove fitting and spring fitting, the outer surface of which is formed by surface areas of both fittings. More preferably, these two screw channels are each located on a flank surface of the groove and tongue.
  • a first component 1 and a second component 2 are connected by means of a connecting fitting 3 according to the invention, the connecting fitting being arranged between two mutually parallel flat surfaces of the components 1, 2 and lying against these two surfaces.
  • connection fitting 3 includes a groove fitting 4, a spring fitting 5 and various screws or threaded bolts. Sometimes screws or threaded bolts are only shown symbolically, namely by dash-dotted lines.
  • the slot fitting 4 is secured by screws 6, which run through screw through-holes in it and into the component 1. rigidly fixed to component 1.
  • the spring fitting 5 is rigidly fixed to the component 2 by screws 7 which run through screw passage bores in it and into the component 2 .
  • the groove fitting 4 has a groove 8 with overhanging flanks.
  • the spring fitting 5 has a tongue 9 - ie a profile-like projection - which is inserted into the groove 8 and which protrudes with cross-sectional areas in both cross-sectional areas of the groove 8 covered by the overhanging flank areas of the groove.
  • a surface area of the groove fitting 4 and a surface area of the tongue fitting 5 jointly delimit two screw channels 10 such that the boundary lines between the two surface areas run parallel to the longitudinal direction of the screw channels 10 .
  • a threaded bolt 11 is screwed into each of the screw channels 10 .
  • the external thread of the threaded bolt 11 is designed as a self-cutting or self-tapping thread, i.e. by screwing the threaded bolt into the screw channel 10, the matching nut thread is formed in this.
  • the line of intersection of the lateral surface of the screw channel 10 with a plane normal to the axis of the screw channel 10 runs in some areas over a surface of the spring fitting 5 and over a surface of the groove fitting 4.
  • the individual threads of the threaded bolt 11 thus each run in a nut thread, which in some areas is in the spring fitting 5 runs and in some areas in the groove fitting 4.
  • the threaded bolts 11 thus transmit forces between the spring fitting 5 and the groove fitting 4 with each thread, which are aligned parallel to the axis of the threaded bolt 11. This means that the derivation of the weight force from one of the components 1, 2 to be connected to the other of these components is not only on the closed end of the groove 8 of the groove fitting 4, but over the entire height of the groove fitting 4 and tongue fitting 5. This avoids local stress peaks and the load-bearing capacity is significantly increased.
  • the groove fitting 4 can be formed from a series of fitting members 12, 13, which are lined up in the longitudinal direction of the groove 8 butting against one another.
  • the fitting members 12 are equal to each other.
  • the specially designed end fitting member 13 is arranged only at one end of the groove fitting 4 .
  • the groove 8 On the end fitting member 13, the groove 8 has a closed end on the face side—and thus a stop surface against the sliding of the spring 9 of the spring fitting 5 out of the groove 8.
  • the cross-sectional area of the groove 8 in the region of the end fitting 13 tapers continuously toward the front end of the groove 8 .
  • the purpose of this - in 2 clearly visible taper 14 is to force the cross-sectional area of the tongue of the spring fitting, which is slightly smaller than the cross-sectional area of the groove 8 in its non-tapered area, into a precisely defined position with respect to the cross-sectional area of the groove 8 and to keep it there while the threaded bolts 11 are screwed into the screw channels 10.
  • the groove 8 in the end fitting 13 tapers to a cross-sectional area into which the cross-sectional area of the tongue 9 fits without play.
  • the spring fitting 5 also consists of a series of fitting members 15, which can all be exactly the same as each other and which are lined up in the longitudinal direction of the spring 9 butting against one another.
  • connection fitting 3 makes it very easy to adjust this by selecting the number of fitting elements 12, 15 to be lined up to the height of the existing connection surfaces between the components 1, 2 to be connected and thus (indirectly) also to the size of the parts to be transferred tune load.
  • the assembly of the components 1, 2 provided with halves of the connecting fitting 3 is always carried out in the same simple manner, in that one component is moved linearly and straight parallel to the alignment of the groove 8 and tongue 9 along the other component, so that the tongue 9 fits into the groove 8 is threaded.
  • groove fitting 4 and tongue fitting 5 are made of aluminum.
