CLASS 47 a: 3 INT. CLASS F 06 b PATENT PERIOD FROM 23 MAY 1958 RELEASED 9 AUGUST 1962 PUBLISHED 30 OCTOBER 1962 Ans. 4964/1958 of 23/5 1958Hdrtill a drawing N G A BLOMQVIST, NACKA Profdfiirband jamte of beams by means of such joints constructed construction The present invention relates to joints of two flanged beams with slits made in either beam or flanges for receiving the flange of the other beam.

Uppfinningen kannetecknas huvudsaldigen av en klamforbindning, som bestar av ett L-format lasj am, i vars ena skankel ett hal dr upptaget, genom vilket en skruv eller bult ãr frigaende ford, varvid bultens ganga in-griper med ett gangat hal i den med slitsar fOrsedda balken, och det gangade halet är sa placerat i forhallande till slitsarna, att namnda lasjarnsskankel griper Over den andra balken, varigenom vid bultens atdragning balkarna fastklammas mid varandra. The invention is mainly characterized by a clamping connection, which consists of an L-shaped lasjam, in one of its shackles a halo of which is received, through which a screw or bolt is released, the thread of the bolt engaging with a threaded halo in it with slots the provided beam, and the threaded tail is so placed in relation to the slits, that said laser iron shank grips over the other beam, whereby when the bolt is tightened the beams are clamped together.

En utforingsform av uppfinningen skall liar narmare beskrivas i anslutning till bifogade ritning, dar fig. 1 visar balkfarbandet i perspektiv och fig. 2 en ay staende och liggande balkar medelst sadana fOrband uppbyggd stomme till hylla med ett flertal hyllplan. An embodiment of the invention will be described in more detail in connection with the accompanying drawing, in which Fig. 1 shows the beam conveyor belt in perspective and Fig. 2 a standing and horizontal beams by means of such joints constructed frame to shelf with a plurality of shelves.

En som stolpe tjanande U-balk 1 uppbar genom friktion en barbalk 2, som medelst en i ett L-format la.sjarn 3 i den likaledes U-formade barhalkens liv eller ryggparti ingangad butt 4 halles fastklamd i en barbalkens hada flansar genomgaende, mot barbalkens langdrikining vinkelrat slits 5. Bultens gangade ande 6 synes i fig. 2 sticka fram i det gangade halet i balken 2, men kan dar alternativt vara forsedd med ett huvud i stallet for ganga, i vilket fall bultens huvud 7 utbytes mot en mutter eller bulten ingangas i delen 3. A U-beam 1 serving as a post received by friction a bar beam 2, which by means of a butt 4 inserted in an L-shaped bar 3 in the like U-shaped bar ridge life or back portion is held clamped in a bar beam's hot flanges throughout, against the longitudinal groove of the bar beam is perpendicularly worn 5. The threaded spirit 6 of the bolt appears in Fig. 2 to protrude into the threaded tail of the beam 2, but may alternatively be provided with a head instead of a thread, in which case the bolt head 7 is replaced by a nut or the bolt is entered in part 3.

Slitsens 5 inre del, som lampligen upptar storre delen av dess djup, bar ha en sadan bredd obetydligt overstigande den ingaende flansens tjocklek, att god styrning mellan balkarna erhalles. Langst ut bar alminstone ett air hornen vara avfasat for underlattande av flansens inforande i slitsen. lVfellan skruvens inuti balken 2 belagna del och lasjarnet 3 bar heist finnas en distansdel for erhallande av tillrackligt presstryck frail jarnets motsatta ande till balken 1. Denna del kan astadkommas genom bojning i rat vinkel ay lasjarnets 3 inre ande. The inner part of the slot 5, which suitably occupies most of its depth, should have such a width insignificantly exceeding the thickness of the impregnating flange that good guidance between the beams is obtained. At the far end, at least one air horn should be chamfered to facilitate the insertion of the flange into the slot. In the case of the screw part inside the beam 2 and the welding iron 3 bar heist there is a spacer part for obtaining sufficient pressing pressure from the opposite spirit of the beam to the beam 1. This part can be achieved by bending at right angles to the inner spirit of the welding iron 3.

Claims

Patent claim:

A joint of two flanged beams with a slit made in either beam of the beam or flanges for receiving the flange of the other beam, marked with a clamping connection, which consists of an L-shaped laser iron (3), in March one shank is accommodated a hollow, through which a screw or bolt (4) is released, the thread of the screw engaging with a threaded hollow in the beam (2) provided with slots (5), and the threaded hollow is so placed in relation to the slits, that the lasjarnskankel grips Over the other beam (1), whereby mid the tightening of the bolt the beams are clamped together.

Joint according to claim 1, characterized in that the slot (5) is wedge-shaped and extended towards the mouth to facilitate the insertion of the flange into the slot, whereby the flange inserted into the slot (5) during the fastening will be wedged.

Bandage according to claim 1 or 2, characterized in that the inner spirit of the laser yarn (3) is bent approximately at right angles and arranged to hold the stand of the laser yarn at a distance from the inner spirit of the bolt (4) at a tight angle of the beams (1 and 2), whereby sufficient compressive pressure from the opposite spirit of the laser yarn (3) to the beam (1) is applied.

4. Constructed from beams by means of joints according to any of the preceding patent claims. Request publications: Patent writings from Sweden 125 498; France 1 139 090. Stockholm 1962. Kungl. Boktr. P. A. Norstedt & Seiner. 020089 Fig .1 GENERAL STAFF
