    PCT No. PCT/SE81/00269 Sec. 371 Date May 7, 1982 Sec. 102(e) Date May 7, 1982 PCT Filed Sep. 17, 1981 PCT Pub. No. WO82/01054 PCT Pub. Date Apr. 1, 1982.Arrangement for frames and the like which are composed of distance elements, for example in the form of tubular struts and holding devices which keep these together in the form of coupling nodes (1), each of which comprises an initial inner portion (7) which is arranged to be clamped in a cavity in one of the elements, and the second outer portion (6) which is arranged to hold a second element by clamping firmly around this by means of outer contact surfaces (16). The coupling nodes (1) consist of two components (2, 2) which are located on either side of a center plane and furthermore there are for example screw devices for displacing these components in relation to each other. By this means the said clamping can be obtained during which the contact surfaces (16) move towards each other. On either side the cavity in the first-mentioned element exhibits surfaces which face away from each other. The first portion (7) of the sections has contact surfaces (21) on the same side of the center plane as the said contact surfaces ( 16). When the sections are displaced and during movement of the first-mentioned contact surfaces (16) towards each other, the contact surfaces (21) of the first inner section (7) are also moved towards each other and thereby make contact with the contact surfaces in the cavity.

    The invention relates to a device for connecting tubular rods of composite frames. The device for this purpose includes spacers in the form of tubular elements and connecting assemblies which are inserted at the end of one tubular element for connecting it with another similar tubular element along its side at a right angle to its longitudinal axis and in some rotated positions. . The purpose of the invention is to increase the strength and reliability of the connection. FIG. 1 shows the connecting node, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 - three connecting nodes and three connecting pipe elements of a 1'1x element with a partial tearing; FIG. 5 shows three connecting nodes with four tubular elements attached; in fig. 6 and 7-- coupling unit, embodiment The device for connecting tubular rods (connecting node 1) includes the stitching of two identical (half) section 2 (in Fig. 1-3 one half is shown by continuous lines, and the other is dashed), screw 3 with internal hex socket and nut 4 (Fig. 5). Each half of the node has an outer 5 and inner 6 parts. The outer part 5 has a pattern. indented to the other half of the stitch surface 7. The tubular elements 8 consist of a thin-walled profile that can be inscribed in an imaginary square. The outer sides 9 of the profile run along the sides of the square, and in the center of the corners of the imaginary square there are grooves made by bending the walls of the bath in such a way that the lower parts of the respective grooves form a wall section 10 that forms an angle of 45 with the outer side walls 9. Side walls The grooves have sections 11 that connect the sections of the walls 9 and 10 and make an angle of 60 relative to the corresponding external side walls 9. Thus, the sections of the walls 9 together with the adjacent sections 1 1 1 form a section of Astka -palastochkina tail. Since the tubular elements must interact with the connecting nodes so that the inner parts of the latter 6 are inserted into the ends of the tubular elements and at the same time the external parts 5 must be able to connect along the tubular profiles as a result of the interaction between the surfaces at the connecting nodes and wall sections 9 and 10 on tubular profiles x, it is advisable that the latter have the same profile along its entire length. However, if other elements are to be connected at any other point, the tubular element has a configuration that differs from the profile shown in the central longitudinal section and prevents the connection. The outer part 5 of the two halves 2 must be clamped around the sections of the tubular element 8 having the outline of a dovetail and rest on two opposite surfaces 11. The outer part 5 is formed by a parallelepiped block having a wall 12, from which the inner part 6. extends. The protrusion 13 has a contact surface 14, which extends from the surface 15 and is directed to the inner surface 7, the surface deviating from the outer end 15. The latter is located at a right angle to the inner surface 7, and the contact surface 14 is uet angle 60 with the end surface 15. In general, the connector assembly opposed surfaces 14 of the two halves form the pinching portion with the profile of dovetail surfaces. In the outer part 5, angular chamfers 16 are made. In the center of the plane and through the outer part 5, there is a hole 17 for the screw 3, which ends with recesses 18 or for the round head of the screw 3, or for the hexagon nut 4. The inner parts are 6 halves, which are placed together in order to form a connecting unit, they are intended to be inserted into the end of the tubular element and at the same time clamped there when the surface 14 of the outer part clamps another tubular element. This means that the tubular element, in the ends of which the parts 6 are inserted, can be fixed at a right angle relative to the second
    3
    the tubular element, onto which the outer part of the connecting assembly can be clamped at any place along the length of the tubular element.
    The inner part 6 has four plank-shaped toothed protrusions 19. Each outer end of these protrusions forms a surface 20, which has the same direction as the inner surface /, but is laid at an angle to it. Surfaces 20 are located above surface 7. Part of each alternate protrusion 19, which projects above surface 7, and surface 20 face one elongated edge of half 2 of the stitch, and alternate protrusions face another side edge. The protrusion 19 also has bevelled chamfers 21, which are located on the opposite side (in the direction at right angles to the inner surface 7) of the protrusion with respect to the corresponding surface 20. The surfaces 21 are formed on small shoulders 22. The protrusions 19 are connected by means of the central part 23.
    The protrusions 19 are arranged one after the other in a zigzag manner relative to the longitudinal axis of the half node.
    The angle between the surfaces 20 of the projections 19 is equal to the angle of the wall. Beers of the preferred embodiment are equal to 120 I. The surfaces 21 on the hanger 22 preferably form an angle of 30 relative to the surface 20, but the differential surfaces are not intended to make any contact, but are free.
    FIG. 1-3, the half of the assembly is shown by continuous lines, and the dotted lines show how the second half of the node of identical shape can be placed in the center against the first half and form a connecting node with two inner surfaces 7 facing one
    other. .I
    As a result of the placement of the protrusions 19, when the halves of the assembly face each other, they fit together so that the respective surfaces face each other (right side, fig. 4). Moreover, the protrusions 19 are linked with each other to ensure an equal gap between them. The halves of the node are connected with the help of screw 3, y) of the lake: from through
    Version 17, its head is located in the recess 18 in one half of the node, and the nut 4 - in the recess 18 in the other half of the node. The pin 24 of pred5 is assigned to control the position of the connecting nodes during assembly, and it is preferable that the holes for the pin in the two halves of the assembly differ slightly in diameter 10 and the pin can be fixed in one. half of the node and passed with some clearance through the second half. However, with completely different halves of the knot, this can be achieved by using a pin with two consecutive diameters.
    Half of the site can be performed by casting, for example, under pressure (Fig. 6). They have the same contact surfaces 14, 20 and 21.
    When two tubular elements 8 are joined together, two halves of the assembly are taken and their internal parts 6 are inserted into one end of the tubular element. The surface 14 of the outer part 5 is bent with a hook over one of the parts having the outline of a dovetail on the second tubular element. These parts are made with the help of parts of walls 9 and 11. When tightening the screw 3, it is possible to clamp the surfaces 14 around the parts 11, as a result of which their angled parts and at the same time the surfaces 15 are pressed to the wall 9 to ensure the clamping density. At the same time, during clamping, the inner parts 6 of the two halves of the assembly are pressed against one another. At first, surfaces 40} on protruding hangers 22 are pressed against the inner walls of all four parts of wall 11. Surfaces 20 must have some gap with respect to parts of walls 11 opposite them, as the tightening continues, because the tubular profile has elasticity, surfaces 11 contact. place for both halves of the node and for
    0 two positions for each protrusion 19 and, thus, in general exceeds 16 positions. These points of contact (the result of the rotation of various protrusions, 19 relative to each other) are symmetrically distributed relative to the central plane.
    The outer parts 5 are pressed against the tubular profile by 5 surfaces 14 facing one another and clamped around the tubular element. Surfaces 21 are also reduced and as a result, they press on the outwardly facing inner surfaces of the tubular member. However, the surfaces 20 of the protrusion 19 are located on the other side of the central plane and are in chevron gearing relative to each other, as a result of which they are further separated when the half of the assembly comes together, and thus make contact with the inside to the central plane) by the surfaces inside the tubular element. Due to this, the annular tubular profile 41 gets a well-distributed contact. With a simple twist of the sleeve, rigid clamping of the tubular elements is achieved by means of connecting nodes, which are provided with dispersed distributed contact surfaces and a clip preventing movement of the components. The end of the tubular element can always be connected to an intersecting tubular element in any place along its length and in four directions that form right angles with each other. With the help of these connecting means it is possible to create an unlimited variety of designs.
