Description
FLANGED JOINT ARRANGEMENT 2223077 The invention relates to a flanged joint
arrangement 5 and in particular, but not exclusively, to a flanged joint arrangement for beams of a lattice structure of a drilling rig.
In the prior art, beams and trusses of lattice structures are joined by providing the ends of the beams with flanges having through-holes for receiving connecting bolts. Lattice structures are used in the offshore construction industry, particularly for constructing drilling rigs which have to be rigidly, rapidly and reliably joined together in situ, i.e. at deep-sea locations. Such large structural components have manufacturing tolerances which have to-;be compensated for when the joint is being established.
The object of the invention is to provide a flanged joint, particularly of the type referred to above, which is suitable for absorbing high tensile and shearing forces, enables the flanged elements to be rigidly and rapidly joined and which can also compensate for deviations in dimensions of the elements in any direction relative to a nominal reference position.
According to the present invention there is provided a flanged joint arrangement comprising corresponding connection elements, each of which elements has a flange portion having apertures for receiving bolt means to thereby join the elements together, and a web portion, wherein the apertures comprise slotted holes, the longitudinal axes of aligned pairs of which are mutually disposed at an angle.
Preferably, the longitudinal axes are disposed at right angles.
Further, a flange portion may be provided on both sides of the web portion.
A secure screwed joint between two eccentrically located beams may thus be guaranteed by the cross-wise facing arrangement of slotted holes in the flange sections according to the invention.
The two connecting elements may be identical as regards the shape and arrangement of the slotted holes. Preferably, an oblique and parallel arrangement of, for example, the sides of a rectangular or quadrangular flanged section, with respect to each other, can is accommodate a simplified storage arrangement. Furthermore, with the slotted holes in these positions, it is possible to arrange a large number of screwed joints without adversly weakening the section of the flange.
The invention is described further hereinafter, by way of example only, with reference to the drawings in which:
Fig 1 is a partial 'section through a flanged joint embodying the present invention; 1 Fig 2 shows a partial plan view of the f langed joint in the direction X of f ig 1 without the screwed j oint; and Fig 3 shows a cut out Y of the flanged joint of fig 2 on an enlarged scale.
The flanged joint shown in Fig 1 comprises two 35 connecting elements, 1, la designed as welded flanges, 1 which are welded onto beams 2, 2a e.g. of a lattice. structure. Each connection element li la has a flange portion 3, having a smooth connecting surface 4, and a web 5 extending perpendicularly thereto. The wall thickness and contour of each web 5 corresponds to "the cross-section of the beam 2, 2a to be welded thereto.
The beam 2 shown in Fig 1 has a retangular shaped cross-section with a central axis 10r such as that of a square tube; as such the flange section extending on both sides of the web 5 comprises a retangular frame. The connecting element 1 is provided with a web 5, adapted according to the beam of the lattice. Thus, if the beam has a circular tubular cross-section, a Y-' shaped or other cross-section, the element 1 is shaped correspondingly.
The flange section 3 has slotted holes 7 on both sides of the web 5, for receiving screw or bolt connectors 6.
The longitudinal axes 8 of the slotted holes 7 are inclinded at an angle 45 0 to the sides 9 of the flange section 3.
The slotted holes 7, as viewed in the direction opposite to arrow xl are arranged at an angle opposite to that described above due to the reverse position of the connecting element 1 a for the beam 2a. Thus, the two longitudinal axes 8, 8a of the mutually facing slotted holes meet at an angle RP = 90 0. Consequently an identical design of the two connecting elements is possible. The longitudinal axes 8, 8a will intersect at the centre of adjacent slotted holes 7 if the central axes 10 of the two beams 2,.2a correspond and the beams 2, 2a are thus concentric. As illustrated by way of Fig. 3r it is possible to shift the slotted holes 7 in opposite relative directions by at least an amount E, so as to guarantee passage for the screw connector 6. The flanged joint of the invention will therefore make it possible to join the two beams 2, 2a even if they 5 are eccentric to a dimension E in all directiofis. Minimum eccentricities of E = 15 mm. at the joint should preferably be possible.
The connector 6 has an appropriate number of prestressed cap screws or bolts 11 with nuts 12 to absorb the tensile force.
A washer 13 is fitted between the bolt head and flange section 3 and /or between the nut 12 and flange section 3.
The washer comprises either a round or rectangular washer 13a with a round through-hole 14 for each bolt 11. Alternatively, it may comprise a frame-shaped plate 13b with through-holes 14 for the screws 11. The whole plate 13b has to be shifted depending on the position of the screws 11 in the slotted holes 7.
It is possible to insert shims 15 between the connecting surfaces 4 of the connecting elements 1, la, to provide. axial compensation when assembling the beams. The shims preferably consist of lmm thick sheets, so that e.g. a maximum construction tolerance of 15mm can be compensated with 15 shims.
The shape of the frame shaped shims 15 corresponds to the flange sectiony and each shim 15 has a plurality of holes for receiving respective ones of the connectors 6. The diameter of each hole corresponds to the longitudinal dimension of the slotted holes 7.
i 1 A different number of shims 15 can be inserted depending on the distance between the two connecting elements 1. la. prior to inserting the connectors 6.
Thus it is possible to align the sheets according to the position of the edges of onel or both or e.g. half the number of the two connecting elementst if the connecting elements are eccentrically positioned with respect to each other.
The connecting elements 11 la are constructed as castings and manufactured from cast steel. It is possible to compensate for any difference in elastic limits of the rolled material of the beam and the cast steel of the connecting elements by way of a step in thickness, wherein the thickness of the flanged section is greater that the wall thickness of the web; depending on the static load requirements. The thickness of the flange section is preferaby at least one and a half to twice that of the wall of the web.
